[0001] The present invention relates to a system using the dynamic force of fluid in floating structure and wind powered vessel using the same. State of the art
[0002] As a wind power generation system, horizontal axis windmills are widely used on land. Countries with a mature windmill market have faced a shortage of suitable locations for installing windmills with sufficient wind energy. Consequently, in these countries, it is necessary to install windmills on the high seas where stable wind strength can be obtained and large areas are available. However, as now, windmills have been installed on the high seas only by a method in which, as in the case of those on land, a windmill is installed on a foundation into a seabed in a maritime area close to coastal strip with very low water depth of about 10 m.
[0003] Since there is an expectation to further increase the offshore installation in the future, development of a practical method for installing a floating structure windmill is required.
[0004] Since electrical energy is required on land, electrical energy needs to be provided on land through electrical wires. To reduce loss during transmission, windmills must be installed close to land, and must be installed in a shallow marine area. For fluctuation of a wind power generation type structure, which is expected as a next generation offshore windmill installation method, a primarily desired method which enables an economical installation in a shallow maritime area with a water depth of about 20 to 30 m.
[0005] When a windmill converts wind energy to rotational force, the mill receives a strong wind force. The strong force of the wind generates a moment which makes the windmill spin. The horizontal axis windmill, which is developed for use on land, receives the wind force at one point by a horizontal rod supported in a high position in the air. Therefore, a huge turning point is generated at the base of a vertical support column of the horizontal axis windmill. In the horizontal axis windmill, the windmill is fixed to rotate around the vicinity of an upper end of the windmill's support column, and the mill has to continue to change its orientation so that the windmill can always face the wind. Therefore, it is impossible to provide support cables to support the support column to receive the aforementioned enormous wind moment. In this way, the support column of the horizontal axis windmill has to be fixed to the ground as firmly as possible, and it is difficult to rotate the windmill together with the support column to change the direction of the windmill. If a turntable is provided on the ground level, the moment of the turnaround of the support column cannot be feared, unless the diameter of the turntable is excessively increased. For this reason, in general, the turntable of a horizontal axis windmill is provided immediately below a nacelle provided at an upper end of the support column. In the meantime, it provides functions necessary for the horizontal axis to generate wind energy, and it is necessary to provide devices, such as a horizontal shaft bearing support system, a reinforcement gear, a power generator, a brake, and a device. control of the throwing of the blade, around the axis of rotation of the windmill. These devices are desirably provided closer to the windmill than to the rotating part, to avoid fluctuation in the rotation torque and interference with the rotation of the rotating part.
[0006] Not only most of these devices, but also peripheral devices including a lubricating oil system, a control panel, or the like are provided in the airborne nacelle. Consequently, the center of gravity of the horizontal axis windmill is located at an extremely high position. In addition, when the horizontal axis windmill is firmly attached to a floating structure, the cylinder centered on the floating structure is enlarged at the upper end of the support column, and then an excessive lateral G force is generated. Therefore, it is disadvantageous that the devices arranged in a nacelle have to have strengths, lubrication systems, and the like to withstand said lateral force G.
[0007] Figure 17 schematically shows, as Comparative Example 1, a relationship between the moment of inclination and stability in a case where a horizontal axis windmill is placed on a floating structure.
[0008] In general, for a floating structure to have a moment of stability, the center of gravity needs to be in a lower position than the metacenter (the point of intersection between the buoyancy line and the centerline of the floating structure) located near the floating structure. In a horizontal axis windmill 200 configured as described above, heavy devices are all located in high positions in the air, and therefore the center of gravity G is therefore higher than the horizontal axis windmill 200 cannot have moment of stability. Suppose a case where the horizontal axis windmill 200 of a type of earth is installed by fixing it on a floating structure 201. In that case, even if the inclination of the floating structure 201 is light, the force of gravity F1 acts on the external side of the buoyancy F2 acting on the floating structure 201, because of a high center of gravity G as shown in Figure 17. Consequently, a force acts to further tilt the floating structure 201. Furthermore, the floating structure 201 receives moments of enormous oscillating twists, due to an F3 wind force received in a high position as shown in figure 17.
[0009] In other words, as long as the floating structure 201 does not have the need for a moment of stability, and receives a huge moment of oscillating twists because of the force of wind F3, there is a problem that said structure is impractical as a floating structure.
[00010] To solve these problems, it is necessary to provide most of all devices in low positions on the floating structure, so that the center of gravity G and the work areas for maintenance are as low as possible.
[00011] In the case of the horizontal axis windmill 200, the swivel must be arranged at an upper end of the windmill support column 202, unless the need for a firm fixation of the windmill support column wind 202 in the floating structure 201, as seen in the example of the onshore windmill can be eliminated earlier. Consequently, all of the above devices are placed in a nacelle 203 above the spinner, so it is difficult to reduce the center of gravity G.
[00012] Figure 18 schematically shows, as Comparative Example 2, a relationship between the slope and the moment of stability in a case, where the vertical axis windmill is placed on a floating structure, where part (a) shows a state with an increased inclination, and part (c) shows a state with an increased inclination.
[00013] In contrast to the horizontal axis windmill 200 of Comparative Example 1, the center of gravity G of a vertical axis windmill 300 as shown in figure 18 should be reduced to a large extent, because all heavy devices can be provided not high in the air but on a floating structure 301 as in the case of land where heavy devices are generally provided on a base. However, as seen in an example on the ground, in a case of a vertical axis windmill 300 in which the support column 302 by itself rotates with a rotor, it is difficult to fix the support column 302 in such a way that resists a turnaround moment due to the force of wind F3, and it is necessary to provide support cables (not shown) in the four directions to support an upper end of the support column 302. This requires a floating structure having a wide deck surface not less than a size required for a floating body. In addition, part of the problem of the support cables, the reduction of the force of gravity to this dimension causes the following problem. Specifically, when the slope of the buoyancy structure 301 due to the force of wind F3 or similar is less than shown in part (a) of figure 18, a moment of stability is exerted by the amount of lateral deviation from the buoyancy center C is greater than the amount of the lateral deviation of gravity G by slope. As the inclination still increases, as shown in part (b) of figure 18, the lateral deviation of the gravity scepter G eventually becomes equal to the lateral deviation of the center of buoyancy C, and the moment of stability is lost. With more inclination, a force causing more inclination acts as shown in part (c) of figure 18. To place it differently, there is a problem that the moment of stability is lost and the floating structure 301 is dropped when the angle of inclination exceed a certain value. This is a phenomenon that occurs because of the following reason. Specifically, when the center of gravity G is located above the floating structure 301, the center of gravity G is deflected laterally when the slope increases.
[00014] Here the float center C cannot be located on the outside of the floating structure, the lateral deviation from the center of gravity G exceeds the lateral deviation from the center of buoyancy C. This problem is inevitable, unless the center of gravity G is located not above the waterline of the floating structure 301.
[00015] Figure 19 schematically shows, as Comparative Example 3, a relationship between the slope and the moment of stability in a case where the vertical axis windmill is supported to be unable to tilt with respect to the floating structure, and a ballast is provided in the water.
[00016] For an ordinary yacht, a stability system has been achieved in which a ballast is provided in the water so that a moment of stability is exercised with any inclination. By applying such a yacht stability system, a vertical axis windmill 400 is conceivable in which, a support column 403 is supported to be unable to tilt with respect to a flotation structure 401, and a ballast 402 is provided in the water, as shown in figure 19. Vertical axis windmill 400 can be reached because the center of gravity G is lower than the center of rotation (center of fluctuation C) of the moment of inclination in the vicinity of the floating structure 401. However, in this way, an excessive tension is placed on a connection part 401a of the support column 403 for the floating structure 401. And then it is impracticable to support the support column 403 only by the connection part 401a. This shape can be achieved only when the cables (not shown) called the bow prop or the bow prop support the 403 support column are provided in three or four directions, as in the case of the vertical axis windmill support cables. In addition, when this occurrence is directly applied to the wind power generation system operated when anchored at sea, operators are exposed to the danger because the floating structure 401 is very inclined with the support column 403. In addition, the load on the monitoring system which is influenced by the inclination of the floating structure 401 excessively increases particularly in the shallow areas.
[00017] Several methods have been studied so far to overcome the insufficiency at the moment of instability of the said floating structure. Examples of proposed methods include a method in which multiple horizontal axis windmills are all arranged on a single large floating structure; a method in which multiple horizontal axis windmills are arranged and floating structures supporting the horizontal axis windmills, respectively, are rigidly linked together (see, for example, Patent Document 1); a method in which stability is obtained by using a floating structure, called a mast, having a cylindrical shape elongated in the longitudinal direction and extending deeply below the water. (see, for example, Patent Document 2), a method called TLP in which a buoyancy structure is stability being pulled towards the ocean floor by metal pipes called tendons or the like (see, for example, the Patent Document 3); and the like.
[00018] However, each method has a disadvantage in that the size of the floating structure is too large for the amount of energy captured by the system from the force of the wind, as well as construction costs and installation costs. too many, making the method economically impractical. However, each method is based on a conception in which a certain depth of water is required, considering the change in the design of the large structure due to agitation, the design of the vertically elongated structure, the range of geometric movement of the tendons pulling in the direction longitudinal, and similar. Consequently, these methods have the disadvantage that these methods are not suitable for installation close to the shallow areas close to the land where electrical energy is required as mentioned above.

[00022] PROBLEMS TO BE SOLVED BY THE INVENTION
[00023] The present invention has been developed taking into account the circumstances described above in order to provide a system for using the dynamic force of fluids in the floating structure that is capable of responding to the turnaround moment due to the dynamic force of fluids and suppressing the slope and to increase the size of a floating structure, and the vessel by wind propulsion using the system of using dynamic force in floating structure.
[00024] Means for solving problems
[00025] The present invention provides a system for using the dynamic force of fluids in the floating structure comprising the assembly for the extraction of energy from water or wind; a floating structure to support the assembly, the assembly includes a dynamic force receiving part of the fluid and a support column to support the force receiving part, and the assembly has a center of gravity set out below and is tilted at any angle direction with respect to the floating structure.
[00026] In accordance with the present invention, the center of gravity of the assembly is established below the water, and the assembly is tilted in any direction with respect to the floating structure. Consequently, the set is tilted in any direction under the receipt of a dynamic fluid force, while a force of gravity acts on the center of gravity present below the water generating a moment of stability which is centered on a supporting part of a tilt rod and which acts to correct the tilt. As the slope increases, the moment of stability increases, and it never loses. Thus, the set itself can handle the moment of the set's turn. For this reason, the floating structure does not need to divide the turnaround moment, and thus it is unnecessary to provide support cables, so that the size of the floating structure can be reduced. In addition, since the floating structure the set is supported inclinately with respect to the floating structure, the inclination of the set does not cause inclination of the floating structure.
[00027] Note that, it is possible for any of the sails, a fixed blade, and a horizontal or vertical windmill, which receives the wind, that the tidal flow forces the sail, a keel, a horizontal wheel or vertical water, which receives the force of the tidal flow, and the like is used as the receiving part of force.
[00028] In addition, the configuration can be used, in which the set is supported oscillatingly in relation to the floating structure with any of the connecting pins, a universal joint, a spherical ball-type bearing, and a body support mechanism elastic provided between them.
[00029] According to this configuration, a set having a heavy weight can be supported by a floating structure in a simple and reliable way, at the same time that it is allowed to swing.
[00030] In addition, a configuration can be used, in which the assembly is rotatably supported around a central axis of the support column with respect to the floating structure.
[00031] According to this configuration, when the force receiving part is of a type that has to rotate, the force receiving part is allowed to rotate, while the whole assembly is being fully assembled.
[00032] In addition, the configuration can be used in which at least the wind force is used as the energy of a fluid, the force receiving part includes a wind receiving part to receive the wind force in the air, and the support column includes an upper support column supporting the wind receiving part and a lower support column supporting a ballast fixed below the water.
[00033] According to this configuration, the force receiving part includes the wind receiving part to receive the wind force in the air, and the support column includes the upper support column supporting the wind and air receiving part. lower support column supporting a ballast fixed below water. Thus, while the receiving part of the wind and ballast are supported by the set of support columns, in order to penetrate through the floating structure, the whole set can be supported tilting and rotating in relation to the floating structure.
[00034] Note that, for example, when the wind receiving part is a fixed blade, it is necessary to change the direction of the force receiving part according to the wind direction. In this regard, if the ballast maintains balance in water, it has a cylindrical or spherical shape (a shape with rotation symmetry with respect to the axis of the rotation support column), the upper support column that holds the force receiving part in the air and the lower support column, holding the ballast in the water can be integrated with each other.
[00035] Additionally, a configuration can be used in which the upper support column and the lower support column are coaxially rotationally connected to each other in a state of rigidity with respect to a central axis of the support column with a bearing provided between them.
[00036] According to this configuration, the upper support column and the lower support column are connected to each other coaxially rotationally in relation to each other in a state of rigidity with respect to the central axis of the support column, with the bearing provided between them. Thus, the lower support column and ballast can be configured not to rotate even when the upper support column and the force receiving part are rotating. For this reason, for example, it is possible to prevent the lower support column and ballast from capturing floating objects. In addition, for example, too, when a fixed blade is provided on the surface of the water and a keel and ballast are provided below water, these can be maintained at optimal angles.
[00037] In addition, the force receiving part preferably includes a horizontal axis windmill or a vertical axis windmill.
[00038] According to the configuration, even when the force receiving part consists of a horizontal axis windmill or a vertical axis windmill, the center of gravity of the assembly is adjusted below water, and the whole set, including the windmill, is supported with inclinability in relation to the floating structure. Thus, the assembly can deal with the turning moment and repress the inclination and the increase of the floating structure.
[00039] In addition, a configuration can be used in which the receiving force includes a horizontal water axis wheel or a vertical axis water wheel, the horizontal water and axis wheel or the water wheel vertical axis is fixed below the water and acts as a ballast or part of a ballast.
[00040] According to this configuration, even when the force receiving part consists of a horizontal axis water wheel or a vertical axis water wheel, the center of gravity of the assembly is adjusted below water, and the whole set, including the water wheel, is tilted in relation to the floating structure. Therefore, the turnaround moment can be dealt with, and the tilt and rise of the floating structure can be suppressed.
[00041] Furthermore, since the horizontal-axis water wheel or the vertical-axis water wheel functions as a ballast or part of a ballast, it is not necessary to provide a separate ballast, and the structure can be simplified. In addition, it is possible to employ a configuration in which a windmill and the water wheel are provided in the upper portions and support column.
[00042] In addition, the configuration can be used in which the upper support column and the lower support column are connected together with a gear system provided between them, so as to rotate coaxially, maintaining a predetermined relative rotating relationship , and are supported in a rotating and oscillating manner with respect to the floating structure.
[00043] According to this configuration, the upper support column and the lower support column are connected to each other with the gear system provided between them. Thus, they rotate coaxially with each other, maintaining a predetermined relative rotational relationship. Therefore, it is possible to employ a configuration whereby, when the design of the current flow rate and the design of the wind speed are different from each other, the energy can be extracted from the windmill and the water wheel, which are rotated by the number of their twists in which the windmill and the water wheel are efficient.
[00044] For example, suppose that a case where a referred configuration is used in which the wind receiving part is a vertical axis windmill, the ballast part is a vertical axis water wheel, and the column upper support column and the lower support column are connected to each other with a system of planetary gears and bearings or a differential gear system provided between them, being rigid with respect to the axis, so that the upper support column and the part wind receiving units are rotated several times, during a single rotation supporting the lower column and the vertical axis water wheel. In such a case, energy can be efficiently extracted from both.
[00045] In addition, a configuration can be used in which the upper support column and the lower support column have a mechanism through which the rotation of one of the upper support columns and the lower support column is transmitted to the other under a predetermined condition, as long as the rotation of one of the upper support column and the lower support column is not transmitted to the other under another condition.
[00046] According to this configuration, by incorporating, for example, a gear wheel, a clutch, a viscous coupling, a torque limiter, or similar between the upper support column and the lower support column, the rotations they can be independent of each other, rotation can only be transmitted in one direction, excessive speed can be avoided, or relative rotation can be blocked.
[00047] In addition, the configuration can be employed in which the set includes a rotating energy extraction part for rotating rotation energy extraction from the force receiving part, the upper support column and lower support column are configured to rotate coaxially with each other in directions facing each other, and the rotation energy extraction part is defined in order to allow torques generated by the extraction of rotation energy from the upper support column and the lower support column to cancel each other out.
[00048] According to this configuration, the upper support column and lower support column are configured to rotate coaxially with each other in opposite directions, and the rotation energy extraction part is fixed in order to allow torques generated by means of the extraction of energies to cancel each other out. Thus, the rotation of the floating structure and the load on the anchoring system of the floating structure can be reduced.
[00049] More specifically, for example, when the energy is extracted from a means of rotation of the water wheel, for example, clockwise when viewed from above for the floating structure, a torque to rotate the floating structure clockwise is generated. Likewise, when the energy is extracted from a windmill with a vertical axis of rotation, a torque to rotate the floating structure of the assembly is generated. In these cases, the floating structure rotates, and its anchoring system is twisted. In some cases, the tension of the anchoring system increases because the anchoring system is wrapped around the side faces of the floating structure. The rotation of the floating structure does not stop until equilibrium is reached through the generation of a torque counter that is opposed to the torque. This causes excessive flexing, fatigue in the use of the components of the anchoring system. In this regard, as in the present invention, for example, the directions of travel of the windmill blades with vertical axis and the water vertical axis wheel are defined, or a system of rotating gears of the counter is provided between the column of upper support and lower support column, so that, for example, the lower support column provided with the water wheel and the upper support column provided with the windmill can always rotate in opposite directions. In such a case, the torques cancel each other out, and the problem can be resolved or reduced.
[00050] In addition, a configuration can be employed in which the rotating energy extraction part is an energy generator, including a rotor and a stator, the rotor is connected to any of the support columns and the upper support column lower support column while the stator is connected to the other, and the energy generator generates electrical energy based on the differential movement between the rotor and the stator.
[00051] According to this configuration, the rotor is connected to an upper support column and lower support column, while the stator is connected to the other, and electrical energy is generated based on the detection of differential movement. When the rotational energy is converted into electrical energy and extracted, this configuration makes it possible to cancel the torques with each other and use a smaller energy generator, because a relatively high number of revolutions can be achieved, so that, for example, the number of poles of the power generator can be reduced.
[00052] In addition, the configuration can be employed in which the force receiving part includes a windmill with vertical shaft of the elevator type and a water wheel with vertical axis of the dredge type, and the windmill with axis vertical is activated by the rotation of the vertical axis water wheel.
[00053] According to this configuration, an elevator-type vertical axis windmill, which is generally poor in self-parting property, can be activated by a dredge-type vertical axis water wheel which has relatively good starting property . In addition, since the vertical axis water wheel is provided below the water, the flow of wind blowing into the vertical axis windmill is not influenced, and the reduction in the efficiency of the windmill rotation can be suppressed.
[00054] More specifically, among vertical axis windmills, elevator type windmills typified by Darrieus windmills are generally efficient, and have an advantage that elevator type windmills do not require any adjustment in the wind that blows in any direction of the wind. However, lift-type windmills have a disadvantage where lift-type windmills cannot be started on their own, requiring rotation during startup. To overcome this disadvantage, a gyromill type windmill is developed that can be started by itself, adding a connection mechanism through which the angles of attack are varied between positions, such as a position against the wind and a downwind position. However, the gyromill windmill type requires an adjustment made according to the direction of the wind and the relationship between the speed of rotation and the speed of the wind. In addition, lift-type windmills have the disadvantage as the mechanism is mounted in a position out of reach and, therefore, maintenance of the device is difficult on the high seas. An approach has been put in place in which the insufficiency of self-starting force is complemented by the use of a Darrieus windmill as a main rotor, and in combination with a Savonius windmill, which has a low efficiency, but has a good starting characteristic, or similarly arranged inside the Darrieus windmill.
[00055] However, this approach has a disadvantage that the Savonius mill hinders the wind flow that blows into the Darrieus mill and decreases efficiency. In the present invention, for example, a Darrieus windmill is used, and the Darrieus windmill can be started by means of a Savonius water wheel for the tidal flow force under the water's surface. With this configuration, the Savonius water wheel does not hinder the flow of blowing fluid to the Darrieus windmill.
[00056] In addition, a configuration can be used in which the force receiving part includes a windmill with a vertical axis of the lift type and a water wheel with a vertical axis of the dredge type, the water of the vertical axis wheel is connected to the vertical axis mill with a step-up device provided between them, and the reinforcing device provided between them, and the reinforcing device transmits the rotation of the vertical-axis windmill when a windmill rotation speed with vertical axis after reinforcement is not greater than the rotation speed of the vertical axis water wheel but does not transmit the rotation of the vertical axis windmill to the water of the vertical axis wheel, when the rotation speed of the windmill of vertical axis after reinforcement is greater than the rotation speed of the vertical axis water wheel.
[00057] According to this configuration, the rotation of the vertical axis water wheel is transmitted to the vertical axis windmill, when the rotation speed of the vertical axis windmill after the reinforcement is not greater than the rotation speed of the vertical axis water wheel. Thus, the lift-type vertical axis windmill activation property can be improved. However, the rotation of the vertical axis windmill is not transmitted to the vertical axis water wheel, when the rotation speed of the vertical axis windmill after the intensification is greater than the rotation speed of the water wheel vertical axis. Thus, the vertical axis water wheel does not act as a resistance.
[00058] More specifically, in general, the design of the tidal flow velocity is much less than the design of the wind velocity. In addition, a Savonius rotor is efficient when the peripheral speed of a part with a maximum diameter of the rotor is approximately equal to the speed of the fluid, while a Darrieus rotor is efficient when the peripheral speed is about 4 to 6 times the speed of the wind. Thus, the axial rotation of the Savonius water wheel is preferably transmitted to the axial rotation of the Darrieus windmill after it has been intensified. However, when the wind speed increases, it is preferable that the axial rotation of the windmill is separated from the rotation transmission, so that the water wheel does not serve as a brake, or the transmission is conducted only in a single direction. Note that, since the tidal flow rate is generally very low, but the water has a specific weight of 800 times that of the air, a Darrieus windmill in the air can be started by placing a Savonius water wheel to start the water having a size approximately equal to that of a Savonius windmill for activation arranged in the air. This configuration is especially useful in marine areas, including sea areas near Japan, which have characteristics in which the flow of the tides has a low flow rate, but it is relatively frequent, that the wind speed is fast when a wind blows. , but the wind often vanishes, and that the wind direction is not constant, and so on.
[00059] In addition, a configuration can be used, in which the set has a buoyancy almost equal to the set's own weight and is supported vertically in a mobile way in relation to the floating structure, and a vertical movement of the energy extraction part is provided to extract energy from relatively vertical movements between the assembly and the floating structure.
[00060] According to this configuration, the set has a buoyancy almost equal to the weight of the set and is supported vertically in a mobile way with respect to the floating structure. Thus, when the buoyancy acts on the two, they float due to a wave, the two move vertically with respect to each other because of the difference in buoyancy of the floating structure, with respect to the two.
[00061] So, the vertical movement starts with energy extraction extracts energy (wave energy) from the vertical movement with respect to the floating structure and the set.
[00062] Note that the whole is subjected to a relatively small change in buoyancy due to the fluctuation design, and vertically travels over a long period, because its relatively large weight and the relatively small part of the water surface penetration. Meanwhile, the floating structure follows the waves well due to its relatively small weight and the penetration part of the water surface is large. Thus, the relative vertical movement is generated by the waves.
[00063] In addition, a configuration can be employed, in which the vertical movement of the energy extraction part is a linear generator that includes a translator and a stator, the translator is connected to any part of the assembly and the floating structure, while the stator is connected with the other, and the linear generator generates electrical energy based on the differential movement between the translator and the stator.
[00064] According to this configuration, the vertical movement of the energy extraction part is a linear generator that includes a translator and a stator, and, in the linear generator, in which the translator is connected to any one of the set and the structure floating, while the stator is connected to the other. Thus, electrical energy can be generated directly from the relative vertical movement between the assembly and the floating structure.
[00065] In addition, a configuration can be employed, in which the vertical movement of the energy extraction part includes a mechanism for converting the rotation force, including any ball screw, rack and pinion, a connecting rod mechanism. connecting crank, and a gyroscope.
[00066] According to this configuration, the mechanism for converting the rotation force, such as a ball screw, rack and pinion, a connecting rod-crank mechanism, or a gyroscope converts the vertical movement of rotation . Thus, the energy of vertical movement can be used to generate energy in a generator, more efficient, of energy of the rotation type.
[00067] In addition, a configuration can be employed in which the force receiving part includes at least any vertical axis windmill of the elevator type and water wheel of the vertical axis type of the elevator type, and is activated by rotation force obtained by the rotation force conversion mechanism.
[00068] According to this configuration, the rotation force, obtained by the rotation force conversion mechanism, can be transmitted to the Darrieus mill or a Darrieus water wheel, and used to start the Darrieus mill or the Darrieus water wheel . In addition, wind energy and tidal flow force energy can be integrated and used to generate energy in a rotation type energy generator.
[00069] In addition, the present invention provides a wind powered vessel comprising the above described system for using dynamic force fluid in the floating structure, in which the floating structure is a hull, the receiving force includes a receiving portion of wind to receive the wind force in the air, the support column includes an upper support column supporting the wind receiving part and a lower support column supporting a ballast fixed below the water, a wind propelled vessel includes a propeller that it is defined below the water and is rotated by the wind force received by the wind receiving part substantially around a horizontal axis.
[00070] According to this configuration, the hull can be propelled by the propeller rotated substantially around the horizontal axis, by the wind force received by the wind receiving part. Here, the assembly, including the wind receiving part, and the support column are configured to be tilting in relation to the hull, and the center of gravity of the assembly is fixed below water. Thus, even when a windmill having a large part of receiving enough force to obtain sufficient momentum is discarded, a safe wind-powered vessel having sufficient stability moment can be obtained, and the hull tilt and size increase can be suppressed.
[00071] Note that, during navigation, the assembly is preferably restricted to be tileable only in the direction of the hull roll by a restraining device to restrict the direction of the inclination of the assembly.
[00072] In addition, a configuration can be used in which the propeller of the vessel propelled by wind is arranged on the ballast.
[00073] According to this configuration, for example, the rotation of the windmill with vertical axis is reinforced and transmitted to a rod that penetrates inside the ballast towards the bottom, and converted to the horizontal rotation axis, by a gear cone provided inside the ballast. Then, the propeller can be rotated by propulsion by rotating the horizontal axis.
[00074] In addition, a configuration can be used, in which the ballast or the lower support column acts as an elevator-type keel.
[00075] According to this configuration, the ballast or the lower support column works, like an elevator type keel. Thus, the angle of attack of the keel can be adjusted by rotating the lower support column.
[00076] More specifically, when a vessel moved by receiving a large wind energy sails in a crosswind, the nageva vessel, as it slides downwind and is pushed by it. The same applies to a yacht. In the case of a high-performance yacht, a keel in the water has an angle of attack because of a combined speed of a side-skid speed and a straight forward speed, and balance is maintained because of an elevator to pushing the yacht into the wind is generated on the keel. However, balance is achieved only when lateral sliding occurs to a certain degree. Thus, increasing the resistance of the hull to lateral sliding is inevitable. In the present invention, the rotationally supported keel ballast system makes it possible to provide an angle of attack for the keel, so that an elevator to push against the wind can be generated on the keel even when no lateral slip occurs. Thus, the hull can sail forward, while facing the direction of travel, and the hull strength can be reduced.
[00077] In addition, the configuration can be employed in which the wind powered ship includes two sets, each of which is the set, established in front and rear of the hull, and the two fins rotate to have angles of attack in the same direction when sailing forward in a crosswind, while the keel at one front end and the keel at a rear end have angles of attack in opposite directions from each other during turning.
[00078] According to this configuration, the two keels rotate to have angles of attack in the same direction when sailing forward in a crosswind, while the keel at the front end and the keel at the rear end rotate to have angles of attack at opposite directions from each other during the turn. Thus, a vessel driven by high wind performance with low resistance can be achieved by eliminating a rudder. Effects of the Invention
[00079] As described above, in the system of using the dynamic force in floating structure of the present invention, the set has the center of gravity in the water and is tilted supported by the floating structure. Thus, the present invention can achieve such effects and can cope in times of upheavals, due to the enormous and dynamic and floating fluid force with which the floating structure is not inclined, even when the force receiving part in the air receives a great force and it is tilted, so that the moment of stability of the floating structure can always be maintained, and that safe access for inspection, and similar actions can be provided by an operator.
[00080] Furthermore, when the force receiving part in air or water is exposed to an excessive fluid velocity, the force receiving part spontaneously tilts to release the fluid dynamic force. In this case too, it is possible to achieve such an effect on the flotation structure that is not tilted and retains the moment of stability.
[00081] Furthermore, according to the present invention, since it is not necessary to have steel cables, the increase in the size of the floating structure can be supplied. In addition, whether the mill is of the horizontal axis type or the vertical axis type, most major devices, such as a gearbox, a rotating plate, and a power generator can be arranged on the floating structure. This facilitates inspection and maintenance, and in addition can reduce work at height using a crane required for installation and operating periods as much as possible.
[00082] In addition, since the system is self-supporting and stable even without anchoring it can be reached, the system can be pulled after having been mounted on a pier. Thus, installation costs can be greatly reduced. In addition, using this feature, the present invention can achieve a said effect in which a highly efficient and large wind-powered vessel can be achieved, which is provided with a receiving force facilitating the receipt of sufficient buoyancy to be the major part. of propulsion and which can sail forward and straight without a roll or side slip, even in a cross wind.

Ways to Conduct this Invention <First Configuration>
[000102] A system using dynamic force in floating structure 1 according to a first configuration includes, as shown in fig. 1, a set 12, including a wind receiving part 10, which is fixed in the air to receive the wind and a support column 11; and a floating structure 13 inclinably supporting the assembly. The set 12 includes a ballast 14 for fixing a center of gravity 15 of the set 12 under water. The ballast 14 is located in a part of the lower end of the support column 11. Note that the floating structure 13 is connected to anchors not shown with anchor lines 13a.
[000103] The support structure for tilting the assembly 12 over the floating structure 13 can be connecting pins, a universal joint, a spherical support, a support for the elastic body, or similar. In the following description, a case in which an elastic body of the support structure is made as an example is described with reference to Figs. 2 and 3.
[000104] As shown in fig. 2, the support column 11 includes an upper support column 11a supporting the wind receiving part 10, a lower support column 11b supporting the ballast 14, and a spherical part 17 provided between the upper support column 11a and a lower support column 11b. The support column 11 is arranged in the opening part 13b provided substantially in a center of the floating structure 13, in order to penetrate the floating structure 13. The opening part 13b is formed in a conical shape with an inner diameter that increases downwards . The support structure 20 for supporting the support column 11 is placed on the opening part 13b.
[000105] As shown in Figs. 2 and 3, the spherical part 17 is mounted on an elastic rubber support in the form of a screw 18 and connected to it by vulcanization. An elastic rubber support in the form of a screw 19 is also mounted on the spherical part 17 and connected to them by vulcanization. In addition, outer end portions of both elastic rubber supports 18 and 19 are linked by vulcanization in a spherical shape 20a of the inner surface of the support frame 20. The spherical inner surface 20a is formed in a concentric manner with the spherical part 17.
[000106] The elastic rubber supports 18 and 19 are, for example, members used for seismic-based insulation supports of buildings, and each includes rubber plates and metal plates stacked in one direction (a radial direction of the spherical part) 17) schematically shown in cross-sectional view of part (a) of fig. 3. The elastic rubber supports 18 and 19 have this characteristic that the elastic rubber supports 18 and 19 deform flexibly in response to shear force, but have high stiffness under compression. Thus, the vertical movement, the horizontal movement, and the like of the spherical part 17 are severely restricted because of the compression feature of the rubber in the form of a screw. However, the spherical part 17 is flexibly supported in relation to rotation around a center of rotation, which coincides with the center of the spherical part 17 and the inner spherical surface 20a, due to the shear deformation characteristic of the rubber thread-shaped. For this reason, as shown in part (b) of fig. 2, the assembly 12 can be tiltedly supported with respect to the floating structure 13.
[000107] As shown in fig. 2, the support structure 20 is connected to the floating structure 13 with helical springs 21 provided between them to support the flexible assembly 12, which otherwise slopes to a strip that exceeds the design of the slope range. Note that helical springs 21 are provided, only when necessary, and can be omitted. <Second Configuration>
[000108] A system using the dynamic fluid force in floating structure 1A according to a second configuration is different from the first configuration described above, mainly, in that a horizontal mill axis 30 is used as a part of receiving force and that the the upper support column 11 and that of the lower support column 11b are connected to each other in a relatively rotating manner.
[000109] In the following description, the differences from the first embodiment are described mainly, and the common elements are designated by the same reference numbers and are not described.
[000110] As shown in part (a) of fig. 4, a system assembly 12 using the dynamic fluid force in floating structure 1A has the horizontal axis of the windmill 30 at an upper end of the upper support column 11a. In addition, the upper support column 11a is pivotally connected to the lower support column 11b in a rigid state with respect to a central axis of the support column 11. In a part of the lower end of the lower support column 11b, a ballast 14 is provided for the creation of a center of gravity for the set 12 below the water. The assembly 12 is tiltedly supported with respect to a floating structure 13.
[000111] In relation to the system set 12 using the dynamic force of fluids in floating structure 1A, when the horizontal axis windmill 30 is exposed to an excessive wind speed, the set 12, including the upper support column 11a supporting the mill is inclined, while the floating structure 13 is horizontally stable, as shown in part (b) of fig. 4.
[000112] This slope has an effect of cutting off the wind and an effect of reducing the wind receiving part to a height when the wind speed is low. Thus, the wind force received by the horizontal axis windmill 30 can be greatly reduced. This can reduce the possibility that the horizontal axis windmill 30 will be damaged due to strong wind, and consequently achieve an effect that neither a clearance control system nor a braking system is necessarily required.
[000113] Furthermore, since the set 12 of the system uses dynamic fluid force in floating structure 1A itself, it has a moment of stability, it is not necessary to firmly support the upper support column 11a of the floating structure 13. Thus, as shown in parts (a) and (b) of fig. 5, the horizontal axis windmill 30 can be supported, in order to be able to rotate together with the upper support column 11a, with respect to the floating structure 13. For this reason, a turntable 31, is necessary for a mill horizontal axis wind turbines so that the windmill rotates with the wind direction can be provided not immediately below a nacelle 32 in the air, but close to an upper part of a floor of the floating structure 13 (at a part of the end upper part of the lower part of the support column 11b), as shown in parts (a) and (b) of fig. 6.
[000114] Note that when a windmill support column is rotated, it is generally necessary to maintain the support column, providing steel cables in all four directions as seen in a Darrieus vertical axis windmill on land , because the support column is difficult to correct in a lower extruded. However, in the system using dynamic fluid force in a floating structure according to the second configuration, in a moment of turning of the support column 11, the stability of the ballast 14 provided to penetrate the floating structure 13 is directly supported for a moment, and, consequently, the need to obtain a force contrary to the turning moment of the floating structure 13 is eliminated. Thus, this configuration becomes possible.
[000115] In addition, conventionally, a reinforcement gear, an energy generator, and the like (not shown), which are necessary to be arranged on the nacelle 32, it is desirable to add them in a position closer to the blades of the windmill. wind than the position of the turntable 31 is, can be provided immediately above the turntable 31, that is, in a quarter of machine 33 (see part (a) of fig. 6) near the top of the floating structure platform 13. In this case, the horizontal axis of rotation in the air can be converted into an axis of vertical rotation by bevel gears provided inside the nacelle 32 to rotate a transmission rod inside the upper support column, 11a and can be transmitted to the reinforcement gear and the generating energy in the machine room 33. According to this configuration, each of a spacing control system, a reinforcement gear and a lubricating oil system for them, a power generator, a a control panel for them, a braking system, and a turntable, which is provided in the nacelle 32 in the air in a typical horizontal axis windmill, can be provided on the platform near the floating structure 13 or it can be deleted. Therefore, this configuration achieves a great effect in improving center of gravity, as well as the effects, such as relaxation of marine conditions where maintenance can be performed, reduction of costs and risks associated with maintenance, relaxation of design conditions, such as forces sides on machines, and in the prevention of failures due to G-force or the like.
[000116] As shown in parts (a) and (b) of fig. 6, the engine room 33 and the insert rod part 34 are provided in a part of the lower end of the upper support column 11a. In addition, the rotating plate 31 is provided at the upper end part of the lower support column part 11b. An axle bore 35 is provided in the center of the turntable 31, and bearings 35a and 35a rotatably support the part of the insertion rod 34 are fixed at an upper end and a lower end of the axle bore 35. In addition, a spherical part 17 is provided integrally on an upper face of the lower part of the support column 11b. Thus, in assembly 12, the entire support column 11 is tilted with respect to the floating structure 13, and the upper support column 11 and the horizontal axis windmill 30 are rotatably supported in relation to the floating structure 13. < Third Configuration>
[000117] A system using dynamic fluid force in floating structure 1B according to a third configuration differs from the first and second configurations, mainly in the following three points: (1) a Darrieus 40 veto mill is used as a receiving part force; (2) a Savonius 50 water wheel is used as the ballast 14; and (3) the lower support column 11b is also configured to rotate with respect to the floating structure 13.
[000118] In the following description, the differences in relation to the first and second configurations are mainly described, and the common elements are designated by the same reference numbers and are not described.
[000119] As shown in parts (a) and (b) of fig. 7, 1B system using dynamic fluid force in floating structure according to the third configuration includes, as a part of receiving force, the Darrieus 40 windmill, which is one of the vertical axis windmills of the elevator type. The Darrieus 40 windmill includes an upper support column 11a that serves as a vertical axis, and three blades 41 provided around the upper support column 11a, at regular intervals. Upper end parts 41a and lower end 41b end parts of blades 41 are rotatably supported by an upper support 42 provided on a part of the upper end of the upper support column 11a and a lower support 43 provided on one side of the lower end of the support column. upper support 11a in a vertical direction.
[000120] Central parts 41c of blades 41 are configured in an articulation structure. In addition, the lower support 43 is configured to be able to slide in relation to the upper support column 11a. The blades 41 are configured in such a way that the rotation radius r of the blades 41 can be changed by sliding the lower support element 43 vertically to fold the central parts 41c of the blades 41.
[000121] The Savonius 50 water wheel also has a ballast function 14, and has an upper end part supported by the lower support of column 11b. As shown in part (c) of fig. 7, the Savonius 50 water wheel includes blades 51 and 51, having such shapes that a cylinder divided into two halves, in the axial direction. The two blades 51 and 51 are joined to each other along the divided plane in a way that they move from one another. The Savonius 50 water wheel rotates when a current stream passes through a 51a of the space surrounded by blades 51 and 51. The Savonius 50 water wheel according to the third configuration has a structure in which each of these two phases blades 51 and 51 are vertically placed on top of each other and adjusted so that their phases are displaced by 90 degrees.
[000122] For example, the configuration, dimension, mass, and the like, of the Savonius 50 water wheel are adjusted so that the product of the distance from the center of inclination of the support column 11 to the center of gravity of the Savonius 50 water wheel and the water weight of the Savonius 50 water wheel can be greater than the product of the distance from the tilting center of the support column 11 to the center of gravity of the Darrieus 40 windmill and the weight in the air of the Darrieus 40 windmill. Thus, the water wheel Savonius 50 also functions as the ballast 14, so that the center of gravity of the set 12 is below water, and a moment of stability can be obtained.
[000123] Next, a support structure of the assembly 12 in the third configuration is described with reference to parts (a) and (b) of fig. 8.
[000124] As shown in part (a) of fig. 8, the upper support of the column 11a, the lower support column 11b, and the spherical part 17 are connected to each other in a relatively rotating manner, in the third configuration.
[000125] A part of the lower end of the upper support column 11a is integrally joined to an upper part of a connecting component 11c, by means of a cone rod. The lower end of the connecting member 11c is inserted into the upper end part of the lower support column 11b and rotatably connected thereto. In addition, an upper end of the connecting member 11c is formed having a tapered shape with a diameter decreasing upwards, and inserted into a hole of the part 11a1 being formed in the lower end part of the upper support column 11 'having an inverted conical shape. A thread is formed at an upper end part 11c1 of the connecting member 11c .. Tightening the nut N causes the connecting member 11c to move the lower support column 11b to the upper support column 11a, and these are integrally joined together the others. Bearings B are arranged in suitable positions between the connecting element 11c and the lower support column 11b, and the connecting member 11c and the part of the lower supporting column 11b can rotate with each other. In addition, the spherical part 17 is adapted in another part outside the upper end part of the lower support column part 11b. A bearing of B is provided between the spherical part 17 and the lower supporting column part 11b, and the spherical part 17 and the lower supporting column part 11b can rotate with respect to each other. The spherical part 17 is inclinably supported by a support frame 20 with elastic rubber supports 18 and 19 provided between them. Thus, the upper support column 11a, the lower support column 11b, and the spherical part 17 can rotate with respect to each other, while being firmly connected to each other in a rigid state in the axial direction, and are tilting with respect to the structure float 13, as shown in part (b) of fig. 8.
[000126] A cylindrical part 11d having a cylindrical shape and an open upper part is formed in a part of the upper end of the lower part of the support of the column of 11b. In addition, a gear system 60 and a power generating device 70 are arranged between the cylindrical part 11d and 11c of the connecting component (i.e., between the upper support column and the lower support column da11b).
[000127] The gear system 60 includes, for example, a planetary gear system, and has a coaxial rotation function with respect to the upper support column 11a and the lower support column 11b in opposite directions from each other. The gear system 60 includes a sun gear 61 carved around the lycconnecting element 11c, a crown gear 62 connected to the cylindrical part 11d with a ratchet mechanism 64 described later and interposed between them, and several planetary gears 63 adapted between the solar gear 61 and the gear ring 62. The planetary gears 63 are connected to the spherical part 17 in an immovable manner by a conveyor not shown. Thus, for example, when the water wheel Savonius 50 and the lower support of the column 11b seen from above begin to rotate clockwise because of a current flow, the gear system 60 causes the upper support column 11 and the Darrieus 40 windmill seen from above start the rotation (it is activated) in a counterclockwise direction. This can improve an activation property of the Darrieus 40 windmill.
[000128] In addition, the gear system 60 also has the function of a reinforcing device to intensify the rotation of the lower support column 11b and transmit the reinforced rotation to the upper support column 11a. For example, by adjusting a gear ratio of the planetary gear system, an adjustment can be made, in which, when the Savonius 50 water wheel (ie, the sprocket 62) is turned once, the Darrieus 40 windmill (ie solar gear 61) can be rotated several times (for example, eight times). Thus, the rotation speed of the windmill design and the rotation speed of the water wheel design can be adjusted appropriately according to the wind speed and flow rate.
[000129] For example, a case where a project where a tidal flow rate during activation is 0.3 m / s and a wind speed during activation of 3 m / s is described. In order for the Darrieus 40 windmill to start spontaneous rotation, which is necessary to activate the Darrieus 40 windmill, so that the peripheral speed of the Darrieus 40 windmill is about three times the wind speed or higher , that is, about 9 m / s or higher. When the radius r of rotation of the Darrieus 40 windmill is 20 m, it is necessary to rotate the Darrieus 40 windmill at 4.3 rpm. On the other hand, the Savonius 50 water wheel rotates only at a peripheral speed approximately the same as the current flow. When the Savonius 50 water wheel has a radius of 5m, the peripheral speed is about 0.6 rpm.
[000130] Thus, the rotation speed of the Savonius 50 water wheel is intensified 8 times by the planetary gear system provided between the upper support column 11a, which is the axis of the windmill, and the part of the lower support column 11b , which is the water wheel axle, and the increased rotation is transmitted to the 40 Darrieus windmill. In this case, the fluid speed is reduced to 1/10 when compared to a case where the Savonius 50 water wheel is provided in the air. Thus, if the specific weights of the fluids are equal, the torque generated is 1/100, which is the square of 1/10, and the torque is further reduced to 1/8, due to the intensification. Therefore, the torque to activate the Darrieus 40 windmill is 1/800. However, since the specific gravity of the fluids increases by 800 times, in reality, the Darrieus 40 windmill can be activated by a Savonius 50 water wheel in a size approximately the same as that of an earth type.
[000131] The ratchet mechanism 64 has a function of not transmitting the rotation of the upper support column 11a to the part of the lower support column 11b under a predetermined condition. Specifically, when the Savonius 50 water wheel in a stopped state starts to rotate, the rotation of the Savonius 50 water wheel is transmitted to ring gear 62, via ratchet mechanism 64. With rotation of ring gear 62, the windmill Darrieus 40 connected to the solar gear 61 starts to rotate at a speed eight times faster than the water wheel Savonius 50 in the opposite direction. So, the rotation speed of the Darrieus 40 windmill reached a speed that is eight times that of the Savonius 50 or higher water wheel (i.e., the increased rotation speed of the Savonius 50 or higher water wheel) because of the wind force, the ring gear 62 is executed idly with respect to the ratchet mechanism 64. Thus, the rotation of the windmill Darrieus 40 is no longer transmitted to the water wheel Savonius 50. Thus, the water wheel Savonius 50 does not serve as a load (brake) Darrieus 40 windmill.
[000132] The power generating device 70 having a rotor 71 and a stator 72 is disposed inside the cylindrical part 11d and below the gear system 60. The rotor 71 is fixed to the connecting element 11c, and the stator 72 it is fixed to the cylindrical part 11d. Therefore, rotor 71 and stator 72 rotate in opposite directions, on the power generating device 70. Thus, the power generating device 70 can efficiently generate electrical energy from the speed difference between rotor 71 and the stator 72.
[000133] Here, a torque counter acts between rotor 71 and stator 72. However, rotor 71 and stator 72 are fixed, respectively on the upper support column 11 and on the lower support column 11b, which rotate in opposite directions. Thus, the torque counter is canceled. For this reason, an anchoring structure to prevent rotation of the floating structure 13 can be simplified and reduced in size.
[000134] Note that, in the third configuration, a ratchet 75 is also arranged between the cylindrical part 11d and the spherical part 17. Thus, even when, for example, there is no current flow, electrical energy can be generated without co-correction of the lower support column 11b with the upper support column 11a.
[000135] Next, a retractor mechanism of the Darrieus 40 windmill in the third configuration is described with reference to fig. 9.
[000136] As shown in fig. 9, the blades 41 of the Darrieus windmill 40 can be deformed in straight line shapes by sliding the lower support element 43 downwards in relation to the upper support column 11a. Thus, the radius r of rotation of the Darrieus 40 windmill can be made, substantially at zero, so that blades 41 can be prevented from being damaged by a strong wind, the turnaround moment can be reduced, reducing the area of rotation. receiving wind. <Fourth Configuration>
[000137] A system using dynamic fluid force in a floating structure 1C system according to a fourth configuration is different from those of the first and third configurations mainly in the fact that a set 80 has buoyancy by itself, that the electrical energy is generated based on the difference in vertical movement, due to the waves between the set 80 and a floating structure 13.
[000138] As shown in fig. 10, the floating structure 1C the system using dynamic fluid force according to the fourth configuration includes the assembly 80 having buoyancy, and the floating structure 13 supporting the assembly 80 tiltably, in a rotating manner, and in a vertically mobile manner.
[000139] The set 80 essentially includes, for example, a vertical-axis Darrieus water wheel 81 and a support column 82 that serves as an axis of rotation. The assembly 80 has sufficient buoyancy for the assembly 80 alone to float on a water surface by, for example, forming the support column 82 by a hollow member. The set 80 is formed in a vertically elongated shape, and therefore is less likely to be influenced by the vertical movement of the water surface, due to the waves. On the other hand, the floating structure 13 is more likely to be influenced by the vertical movement of the water surface, due to the waves than the set 80. For this reason, the set 80 and the floating structure 13 move vertically with respect to the another, depending on the difference between the speeds of response to the waves.
[000140] Set 80 is tiltable by floating structure 13. Therefore, even when a large current flow force is exerted, set 80 can be tilted to release the tidal flow force, as shown in part (b) of fig. 10. In addition, since the vertical axis water wheels 81 act as ballast, the assembly 80 can restore a vertical state.
[000141] Furthermore, since the set 80 is rotationally supported in relation to the floating structure 13, the tidal energy flow can be extracted when the power generation device 70 described later (see fig. 11) is rotated by the rotation of the set 80.
[000142] In addition, the assembly set 80 is vertically supported in a movable manner in relation to the floating structure, and includes a mechanism for converting the rotational force 88, to convert the vertical movement of the rotating force. Thus, the vertical movement relative to the set 80 can be converted into a rotation movement, and used as the activation force of the Darrieus 81 vertical axis water wheel.
[000143] Next, a support structure of the floating structure 1C system using dynamic fluid force according to the fourth configuration is described with reference to fig. 11.
[000144] As shown in part (a) of fig. 11, a spherical part 17 of the assembly 80 is inclinably supported by a support frame 20 with elastic rubber supports 18 and 19 provided between them, as in the case of the other configurations described above. An upper end 83 of the supporting column part 82 serves as a rotation rod of the vertical axis water wheel of rotation 81 is located in a central part of the spherical part 17 in a vertically penetrating manner.
[000145] A ball bushing 86, which is a linear motion bearing, is adapted at the upper end part 83 of the support column 82. Ball bushing 86 is movably arranged in the vertical direction (axial direction), with respect to the upper end part 83 of the support column 82. On the other hand, the ball liner bushing 86 is held by the spherical part 17 in an immovable vertical form. In addition, ball linear bushing 86 engages with a groove 86a notched in the upper end portion 83 of the support column 82, and therefore is configured to rotate with the support column 82. A rotor 71 of the generating device of energy 70 is fixed # 86, and a stator 72 is fixed to an internal peripheral surface of the spherical part 17. Thus, when the vertical axis water wheel Darrieus 81 rotates the rotor 71 it rotates together with the ball bushing 86 The stator 72 does not rotate because it is fixed to the spherical part 17. Thus, the electrical energy is generated based on the relative rotation between the rotor 71 and the stator 72. Note that a torque counter generated in the stator 72 is loaded on an anchoring system of the floating structure 13.
[000146] A screw valve 83a is sculpted in a part of the upper end part 83 of the support column 82 that extends beyond the spherical part 17 and a nut 84 is fixed on the part. Thus, the so-called ball-screw mechanism is formed. On the other hand, a retaining nut for the cylindrical part 17 is formed in an upper part of the spherical part 17 in a protruding manner, and keeps the nut 84 in a rotating direction in a vertical and immovable direction, with a ratchet mechanism 85 provided between them . Thread 83a, nut 84, ratchet mechanism 85, and part 17a constitute the rotation force conversion mechanism 88. This rotation force conversion mechanism 88 activates the vertical axis water wheel 81.
[000147] Specifically, for example, the ratchet mechanism 85 is provided so that the nut 84 seen from above can turn to the left (it becomes free with respect to the ratchet), but cannot rotate in the clockwise. In addition, the Darrieus 81 vertical-axis water wheel is provided for counterclockwise rotation. In addition, the thread of the screw 83a is sculpted so that when the support column 82 seen from above is rotated to the left in relation to the nut 84, the support column 82 moves downwards in relation to the nut 84 .
[000148] Then, when the assembly 80 moves upwards with respect to the nut 84 (the floating structure 13) with the vertical axis water wheel 81 being in a stopped state, the nut 84 rotates in the opposite direction, due to the screw thread direction 83a. Here, the ratchet mechanism 85 travels idle.
[000149] On the other hand, when the assembly 80 moves down in relation to the nut 84 with the vertical axis water wheel 81 being in a stopped state, the nut 84 tries to turn clockwise because of the direction of the thread 83a, but cannot rotate due to the restriction by the ratchet mechanism 85. For this reason,
[000150] vertical axis water wheel 81 rotates counterclockwise and moves downwards. Thus, the vertical axis water wheel 81 is activated.
[000151] After the vertical axis water wheel 81 is activated and starts to rotate to the left, the vertical axis water wheel 81 tries to move downwards in relation to nut 84. However, the water wheel of vertical axis 81 has buoyancy, and therefore is in a state where the vertical axis water wheel 81 can no longer move in the vertical direction after moving down to some degree. In this state, like the vertical axis water wheel 8, the nut 84 rotates in the opposite direction to maintain the relative position relationship with the vertical axis water wheel 81. Here, the ratchet mechanism 85 travels idle.
[000152] Thus, the vertical axis water wheel 81 rotates, and the power generating device 70 generates electrical energy.
[000153] Note that, although not illustrated, an auxiliary generation device including a linear generator (not shown) can be placed between the linear ball bushing 86 and the support column 82. In the linear generator, for example, a translator is connected to the ball bushing 86, and a stator is connected to the upper end part 83 of the support column 82. With this configuration, electrical energy can be generated using the vertical movement with respect to the ball bushing 86 and the support column 82.
[000154] In addition, in the fourth configuration, the ball-screw mechanism, including the screw thread 83a and nut 84, is used as a mechanism for converting the rotational force. However, a ratchet and pinion mechanism, a crank rod connection mechanism, a turning mechanism, or the like, can be employed instead of the ball-screw mechanism.
[000155] Next, a wind propelled vessel 100 according to a fifth system configuration using fluid dynamic force in floating structure is described with reference to fig. 12.
[000156] As shown in fig. 12, on the wind powered vessel 100 according to the fifth configuration then called a yacht, and includes a hull 101 that serves as a floating structure and a fixed blade 102 that serves as an assembly. The fixed blade 102 has a support column assembly 103 determined to penetrate hull 101. The support column 103 is tilted and rotatably supported by hull 101. In addition, the support column 103 includes an upper support column 103a on a upper side of a support mechanism 101a of hull 101 and a lower support column 103b on a lower side of the support mechanism. The bottom support column 103b is a part which is formed to be wide in the front-rear directions and functions like a keel. A ballast 104 is disposed in a part of the lower end of the lower support of the column 103b. Due to the ballast 104, the center of gravity of the fixed blade 102 is defined below the water. A damping device 105 for restricting the inclination of the support column 103 in the front-rear direction is disposed inside the hull 101. A base end of the damping device 105 is connected to the hull 101, and an end of the tip of the damping device 105 is connected to an upper part of the keel of the lower support column part 103b.
[000157] Note that the support mechanism 101a which tiltably supports the support column 103 is not particularly limited, and, for example, the support mechanisms described in the second to fourth configurations can be employed as appropriate.
[000158] When the wind powered vessel 100 sails in crosswind the keel of the lower support of column 103b is rotated to create an elevation angle, so that it slides sideways so that crosswind can be avoided. Then the wind powered vessel 100 can sail, with hull 101 facing forward. In addition, in relation to the ship moved by the wind 100, even when the fixed blade 102 receives a great force corresponding to the wind force and is tilted, the hull 101 does not rotate, and the lower supposition column 103b and the ballast 104 are inclined to provide a moment of stability. This can prevent loss of comfort due to hull tilt 101, increased hull strength, increased strength due to a check command required because the center of resistance is shifted in the transverse direction, which makes it possible to achieve an efficient yacht.
[000159] Note that when the upper support column 103a is rotatable, the support column is difficult to fix the lower end. Thus, in general, it is necessary to provide a bow prop and a side prop as seen on a conventional yacht and steel cables, as seen on the Darrieus vertical axis windmill on land. However, the wind powered vessel 100, the turnaround moment of the upper support column 103a is directly supported by the stability moment of the ballast 104 and the lower support column 103b provided to penetrate hull 101. Thus, hull 101 does not have to endure the moment, and therefore these can be omitted.
[000160] Next, a wind powered vessel 110 according to a sixth configuration is described with reference to Figs. 13 to 16 The ship propelled by wind 110 according to the sixth configuration is different from the ship propelled by wind 100 described above according to the fifth configuration mainly in that the wind receiving part includes windmills Darrieus 40 and where propellers 116 rotated by the rotation of the Darrieus 40 windmill are provided.
[000161] As shown in parts (a) and (b) of fig. 13, the wind powered vessel 110 includes two assemblies 112 and 112 at the front and at the rear of a hull 111. Each of the assemblies 112 is tilted and rotatable in relation to hull 111, with a support mechanism 111a provided between they. Each of the sets 112 mainly includes a support column 113 supporting a force receiving part of the Darrieus windmill 40 as a force receiving part. The structure of the Darrieus 40 windmill is the same as that of the third configuration and will not be described in detail.
[000162] The support column 113 includes an upper support column 113a and a lower support column 113b. The upper support column 113a is a part that functions as an axis of rotation for the Darrieus 40 windmill. The lower support column 113b is a part that is formed to be large in the front and rear direction and functions like a keel. A ballast 115 is arranged on a part of the lower end of the lower support column 113b. Ballast 115 has a propeller 116, which rotates with the rotation of the Darrieus 40 windmill. The support column 113 is configured to tilt only in one bearing direction by a restriction device 117. The restriction device 117 includes, for example, example, a shock absorber or similar.
[000163] As shown in parts (a) and (b) of fig. 14, assembly 112 is configured to tilt in relation to hull 111. As for wind powered vessel 110, even when assemblies 112 receive a large force corresponding to the force of the wind, and are inclined, hull 111 does not roll, and lower support columns 113b and ballasts 115 are inclined to create a moment of stability. This can prevent loss of comfort due to hull tilt 111, increased hull strength, and after increased strength due to a check command required because the center of resistance is launched in the transverse direction, which makes it possible to obtain of an efficient wind-powered vessel.
[000164] As shown in fig. 15, the support mechanism 111a includes a spherical part 113c formed in an upper end part of the part of the lower support column 113b, of elastic rubber supports 18 and 19 tiltingly supporting the spherical part 113c, and a support frame 20 supporting the elastic rubber support 18 and 19.
[000165] A cylindrical part 113d opened downwards is formed in a part of the lower end of the upper support column 113a. The cylindrical part 113d is rotatably secured by the spherical part 113c. A reinforcement device 120 is disposed within the cylindrical part 113d. Reinforcement device 120 includes a crown gear 121, planetary gears 122, and a solar gear 123. Ring gear 121 is connected to cylindrical part 113d with a ratchet 124 provided between them. The planetary gears 122 are connected to the spherical part 113c by a carrier not shown immovably. The solar gear 123 is notched on an outer peripheral surface of the rotation rod 131 described later. Thus, when the upper support column 113a rotates, the axis of rotation of the wheel 131 with a predetermined spacing ratio.
[000166] At the lower end part of the upper support column 113a, a rotation axis 131 is rotatably supported, suspended. The axis of rotation 131 penetrates the spherical part 113c and the lower support of the column 113b and reaches the ballast 115. A bevel gear 132 is provided on a lower end part of the axis of rotation 131. The bevel gear 132 engages with two bevel gears 116b provided at a front end of a horizontal axis 116a of the propeller 116. Thus, the rotation of the axis of rotation 131 is converted to the horizontal axis of rotation of the 116a horizontal axis, and the rotation of the propeller 116 generates propulsion.
[000167] A power generation device 70 is placed inside the spherical part 113c and below the reinforcement device 120. A rotor 71 of the power generation device 70 is fixed to an outer peripheral surface of the rotation rod 131, and a stator 72 of the power generating device 70 is attached to the spherical part 113c. The rotor 71 rotates with the rotation of the axis of rotation 131, so that the power generating device 70 generates electrical energy. At the anchor, the sets 112 are able to tilt about two axes in roll and spacing directions by releasing the restriction device 117 (see fig. 13), and the electrical energy is generated by the wind received by the Darrieus windmills 40.
[000168] Note that, during navigation, the power generation device 70 is configured to function as a motor to complete rotation force, obtained from the force of the wind.
[000169] When the wind powered vessel 110 sails forward in a crosswind, lower support columns 113b function as keels are tilted in parallel to each other, as shown in part (a) of fig. 16. Thus, keels made up of lower support columns 113b have elevation angles and an elevator to prevent lateral slippage from being generated.
[000170] Furthermore, when the wind powered vessel 110 returns, the lower support column 113b functions as keels and is tilted in opposite directions from each other, as shown in part (b) of fig. 16. Thus, the turning radius can be reduced.
[000171] The above configurations of the present invention are described in detail with reference to the drawings. However, the present invention is not limited to these forms of configuration, but can be changed, as the case may be, within a scope that does not deviate from the scope of the invention.
[000172] For example, the mechanism of vertical movement of the fourth configuration can be added to the mechanism of the system of use of dynamic force of fluids in floating structure system of use 1B according to the third configuration. With this configuration, the Darrieus 40 windmill of the system used dynamic fluid force in floating structure 1B can be activated by the vertical movement of the set 12 in relation to the floating structure 13. Likewise, the vertical movement mechanism of the structure can be added. fourth configuration to the support mechanisms 111a of the 110 wind propulsion vessel according to the sixth configuration.
[000173] Furthermore, in the third configuration, the gear system 60 and the ratchet mechanism 64 are arranged between the upper support column 11 of the lower support column 11b, as shown in parts (a) and (b) of fig . 8.
[000174] However, when it is not necessary to intensify the rotation of the part of the lower support column 11b, the gear system 60 can be omitted, and only the ratchet mechanism 64 can be defined between the upper support column 11 and the lower support column 11b. This configuration makes it possible to transmit the rotation in only one direction or to avoid excessive speed.
[000175] Furthermore, as shown in parts (a) and (b) of fig. 8, the upper support column 11 and the lower support column 11b are configured to rotate coaxially in opposite directions, providing the gear system 60 between the upper support column 11 and the lower support column 11b in the third configuration. However, when it is not necessary to activate the windmill by the water wheel, the gear system 60 can be omitted, defining the directions of the windmill blades and the water wheel so that the windmill and the water wheel water can rotate in opposite directions from each other.
[000176] In addition, on the wind powered vessel 110 according to the sixth configuration, each lower support column 113b functions as a keel and the ballast 115 is configured to rotate fully with each other in relation to hull 111. However , the present invention is not limited to this configuration. Only the bottom support columns 113b serve as keels can be configured to rotate.
[000177] Note that, as a reference example of the present invention, in a case where a set does not tilt in relation to a floating structure, it is described.
[000178] For example, in the configuration of the third configuration of the present invention, the Darrieus 40 windmill, which is a vertical axis windmill of the elevator type, is provided for the upper support column 11, and the water wheel Savonius 50, which is a water wheel with a vertical dredge-type axle, is provided on the lower support column 11b, as shown in the figure. 7. In addition, as shown in fig. 8, the support column 11 is tilted with respect to the floating structure 13. However, for example, when the Savonius 50 water wheel is large enough, it is possible to use such a configuration in which the support column 11 is supported for that is unable to tilt with respect to the floating structure 13. In other words, for example, in an area of the sea, with a great depth of water or the like, it is easy to sufficiently increase the size of the Savonius 50 water wheel. when the windmill Darrieus 40 receives the force of the wind, the turnaround moment, due to the force of the wind, can be sufficiently faced. Therefore, if it is not necessary to employ such a weight by defining that the slope occurs after receiving a wind force or excessive tidal flow force, in order to ward off excess wind force or tidal flow force, or the like , the support column 11 does not necessarily have to be supported tiltingly by the floating structure 13. In this case, it is sufficient to rotate the support column 11 in relation to the support frame 20. Thus, the support mechanism can be simplified by omission of the spherical part 17 and the supports of elastic rubbers 18 and 19.
[000179] In addition, in the configuration of the fourth configuration, only the water wheel is provided. Thus, if it is not necessary to use that weight defining for the inclination to occur after receiving an excessive tidal flow force, in order to remove the excessive tidal flow force, or something similar, the support column 11 does not have necessarily to be supported intentionally by the floating structure 13. In this case, it is possible to use said configuration for the support column 11 to be pivotally connected to the support structure 20 of the fourth configuration, and the spherical part 17 and the elastic rubber supports 18 and 19 are omitted.
