    SYSTEM FOR STORING AND GENERATING ELECTRIC ENERGY FOR AQUATIC AND SUBAQUATIC ENVIRONMENT
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a device for storing and producing energy in an aquatic environment, in particular underwater.
    STATE OF THE PRIOR ART
    The patent document WO2015114440 describes the prior art and proposes such a system comprising a floating platform on the surface of a body of water (lake or sea), provided with an elevator system for raising and lowering weights one by one, to store and generate electricity through an electric motor / generator. The weights are stored in the high position by being attached to one or more floats of which at least a portion is on the surface when said weights are stored in the high position. In the low position, the weights are deposited at the bottom of the body of water.
    Before and after being driven by or driving the elevator system, the weights can be hung and unhooked from the elevator system by the use of underwater robots equipped with an articulated arm.
    The platform and at least part of the floating component of the weights being positioned on the surface, they are subject to winds and surface currents which generates very high anchoring and stabilization costs, particularly if the system must be sized to withstand heavy storms and strong swell.
    When the sea is rough, the movements that the platform will undergo and to a lesser extent the weights stored in the high position, in particular the vertical oscillation movements, may have repercussions on the elevator system, in particular on the cable and disrupt the hooking and unhooking of the elevator system cable weights. The vertical oscillating movements of the weights hung on the elevator system, can also prevent the weight from being deposited gently on the bottom of the body of water and thus generate greater costs of said weights or reduce their lifespan.
    The present invention proposes, among other things, mitigating or eliminating the exposure to the wind and the surface current of the platform and the weights stored in the high position and of attenuating or suppressing the movements of the platform and their impact on the rigging, stalling and depositing of weights on the bottom of the water body.
    According to the invention, the weights in the high position of energy storage and the platform of the elevator are stabilized to a depth such that the effect of wind and currents are greatly reduced.
    SUMMARY OF THE INVENTION
    Firstly, a first object of the invention is to provide a storage system and electrical energy generation to cope with alternating power consumption peaks with low consumption.
    Another object of the invention is to provide a system for storing and generating electrical energy in large quantities.
    Yet another object of the invention is to provide an autonomous storage and power generation system that operates on demand as a function of consumption peaks.
    Another object of the invention is to provide a solution that uses the available space, in the most ecological way possible, and is protected from the weather.
    To do this, the invention provides a system for storing and generating electrical energy for the aquatic environment, comprising: a plurality of weights whose density is greater than that of water. - A lift-generator, arranged in cooperation with the weights and arranged to allow, in generator mode, the descent in the bottom zone said weight, and, in motor mode, to go up to the surface said weight; - A platform, adapted to support the upper portion of the elevator-generator when it is loaded or unloaded weight (135). This platform will be named PAG in the remainder of this description (generator lift platform). anchoring cables connecting the PAG platform to the bottom of the water body and exerting a force on the platform downwards to maintain the platform to a sufficient depth below the surface and to prevent it from rising 'at the surface. - floats attached to the PAG platform, exerting an upward force, opposite to the anchoring cables and allowing the platform to be maintained at the desired depth and to prevent it from sinking, particularly when the lift is loaded a weight. - A second platform to suspend the weights when they must be stored in the high position. This platform will be named PAP in the remainder of this description (platform for hooking weights). This PAP platform is located below the surface and maintained at a given depth near the platform of the PAG lift. - Anchoring cables connecting the PAP platform to the bottom of the body of water allow to maintain it to a sufficient depth below the surface of the body of water. floats attached to the platform PAP or included in said platform, allow it to prevent it from sinking especially when it is loaded with weights hanging on it. These floats may consist of a flexible gas tank or a rigid tank filled with water or gas. These floats are provided with orifices for injecting or discharging gas or water from a means such as a compressor, so that it is possible to modify the volume of gas that they contain and therefore their floating power. This characteristic makes it possible to permanently adapt the floating power of the PAP platform according to the number of weights hanging on it and thus reduce the thickness and the cost of the anchoring cables connecting the PAP platform to the seabed. - a reversible motor or a motor and an electric generator, cooperating with the elevator-generator and allowing, in generator mode, the production of electrical energy thanks to the action of the weights during their descent, and, in motor mode , the actuation of the elevator to perform a rise in weight.
    According to such an architecture, the invention proposes an on-demand solution that makes it possible to manage the peaks of electrical consumption as well as the slower periods.
    According to an advantageous embodiment, the system has a reversible motor or a motor and a generator, carried by the platform of the elevator (PAG), which cooperates with the upper portion of the elevator-generator.
    According to another advantageous embodiment, the elevator-generator is constituted by a set of pulleys operating a belt between the platform PAG and the bottom of the body of water.
    According to another advantageous embodiment, the set of pulleys comprises one or more pulleys close to the surface (203) carried by the platform PAG and one or more ground pulleys.
    According to another advantageous embodiment, the pulleys carried by the platform PAG, in particular the surface pulley (103), cooperate mechanically with the reversible motor via a transmission.

    Also advantageously, the weights are substantially elongated.
    Also advantageously, each of the floats of the PAP platform comprises a fluidic flow management control of the amount of air and water in fluidic cooperation with the inside of the tank and the outside of the platform. The invention also provides a method for storing and generating electrical energy for the aquatic environment, comprising the steps of: - in generator mode, ensuring the descent into the bottom zone of a plurality of weights using a elevator-generator connecting a platform PAG positioned substantially below the surface to a bottom area, so that the force exerted by the weights allows the elevator-generator to operate a generator in electric power generation mode; and - in motor mode, to go up to the surface, using the elevator said weight, the reversible motor then being in motor mode and ensuring the traction of the elevator-generator.
    According to one embodiment, the barge (floating platform) comprising the compressor can also be positioned several tens of meters below the surface of the water and be connected to the atmosphere by a pipe whose end is floating on the surface; or connected to an air reservoir that may be on the surface or below the surface.

    DETAILED DESCRIPTION OF THE INVENTION
    FIG. 1 illustrates a first embodiment of an electrical energy storage system for a marine and submarine environment according to the invention in which the potential energy is stored by means of a plurality of submerged weights (135) , which as they descend to the bottom of the body of water (126), operate a generator to produce electrical energy. This energy is advantageously produced during periods of high consumption of a main network connected to the system of the invention, in order to relieve the main network of energy production. Conversely, when an excess of electricity is available on the network, the system operates in engine mode by raising the weights (137) one by one from the bottom of the body of water to a height below the ground. area.
    The system advantageously comprises a large number of weights, thus making it possible to transform energy repeatedly (or continuously) in a sustainable manner.
    The illustrated system comprises a main platform PAG (101) comprising floats not shown in the drawing. This PAG platform is stabilized below the surface (125) by anchoring cables (106). The PAG platform is located at a depth of several tens of meters to minimize its exposure to surface currents. This platform comprises a generator lift system consisting of a cable (104) provided at each end with at least one hook (105) and passing through return pulleys (103) and driving pulleys. The drive pulleys are coupled to a motor and an electric generator via a torque reducer, a clutch system and a gearbox. The assembly (102) shown in FIG. 1 comprises the engine, the generator, the gearbox, the clutch, the gearbox and the driving pulleys.
    The motor can be reversible and operate in generator mode, in this case a generator is not needed. The engine and generator are connected by electrical cables (123) to a floating platform (120) at the surface (125). The electric current can then be converted to a different voltage level by a transformer or converted from AC direct current or vice versa by a converter. The transformer and the converter are shown by (122) in the figure. An electrical cable connects the platform (120) to the power grid via an underwater electrical cable (124).
    The system also includes a PAP hooking platform (131) for hanging the weights when stored in the up position. This platform is located near the platform of the generator lift, in particular, to allow the attachment of a weight to the generator lift before stalling said weights of the PAP platform in the power generation phase, and conversely in the storage phase. These operations for hanging or unhooking the weight of the PAP platform or elevator cable can advantageously be achieved by means of slings or a plurality of slings available for each weight.
    The gripping platform PAP comprises a plurality of floats (132) whose variable volume makes it possible to continuously adjust the floating power of said PAP platform to the number of weights attached to it. The floats can be filled (132) or emptied (133) with a gas via a set of compressed gas conduits connected to a compressor (121) located on the floating platform (120)
    The weights in the high position (135) are hooked to the PAP platform by means of a hook cable (134).
    The gripping platform PAP is stabilized and connected to the bottom of the body of water via anchoring cables (136).
    Figure 2 illustrates in more detail the weight hooking platform PAP. It shows winches (201) connected to the anchoring cables (136). These winches have the function of adapting the horizontal position of the PAP platform when needed, in particular to position itself precisely above the place of capture on the PAP attachment platform and the place of deposit of the weights.
    These winches also make it possible to adjust the depth of the PAP platform.
    At least one float duct (205) (132, 133) connects each float and a device (202) for selectively connecting said ducts to the main duct (127).
    Figure 2 also shows in detail the device for attaching weights. This includes the hook cable (134) on which floats (203) are positioned in order to reduce the relative weight of said cables and facilitate their handling as well as that of the hooks (204) by ROV-type underwater robots. or "Remotely Operated Vehicle", in French "unmanned vehicle" (207). A hooking device (206) can take the form of a ring to hook the weight (135) to the hook (204). Alternatively, slings not shown in Figure 2 may attach the weight (135) to the attachment device (206).
    Several slings and hooking device (206) can be attached to each weight (135). All slings may be provided with floats to reduce the relative weight of said slings and facilitate their handling by the ROVs (207). Several slings can also be attached between the hooks (105) and the elevator cable (104)
    FIG. 3 illustrates a variant of the attachment platform (PAP) presented in FIGS. 1 and 2. The floats are constituted by ballasts that can be filled (302) or emptied (301) by one volume of water per an orifice located in their lower part and connecting the inside of these ballasts to the outside of the system. The filling or emptying of these ballasts can advantageously be achieved by the injection of compressed gas through an orifice and a valve located in the upper part and connected via one or more conduits (205) to a compressor located on the surface in a manner similar to that presented in Figures 1 and 2.
    FIG. 4 illustrates a variant of the hooking platform (PAP) shown in FIGS. 1, 2 and 3. Each float is hooked directly to a weight by means of cables (401) passing through an orifice (404) passing through the platform from top to bottom. This port is equipped with a cable locking mechanism that can be controlled remotely, so that when a weight is lifted off the PAP platform, the cable (401) can be locked and secured to the platform at a point closer to the float. By being positioned at a greater depth and because of the greater pressure, the volume of the flexible float will be reduced (403) and it will exert a lower upward force to compensate for the lack of weight. The locking mechanism of the cable can advantageously be similar to conventional brakes used on elevators, hoists, cranes or cable cars. According to a non-exclusive embodiment, each of these mechanisms can be actuated selectively and with a variable amplitude and moved by an electromagnetic, hydraulic or pneumatic electric force conveyed by a circuit (406) connected to a distribution, control device and control (405).
    Figure 5 shows a variant of the system shown in Figure 4. The floats are made of ballasts whose volume of water they contain varies with the depth and therefore the external pressure. Depending on whether the weights will be hooked or unhooked from the PAP platform, the air volume included in these ballasts will be respectively large (502) or reduced (503). As a result, their floating power will drop when they are secured to the PAP platform at a greater depth.
    Figures 4 and 5 show variants for which the injection of a compressed gas via a compressor is not necessary. The invention comprises other variants that can simultaneously combine the variants presented in FIGS. 2, 3, 4 and 5.
    FIG. 6 illustrates a variant of the invention according to which the PAG generator lift platform (605) is secured to the PAP weight attachment platform (601) via a rail system (606) or any other means enabling the PAG lift platform to move on the PAP anchoring platform in one or two axes. Such means may include (but not limited to) systems similar to those used on hoists mounted on cranes, a carriage moved along a rack, or by winches.
    Mobile fins (603) and propeller thrusters (604) may be positioned around the PAP platform to facilitate stabilization thereof when said platform is located in an area affected by underwater currents.
    Figure 7 illustrates a variant of the system shown in Figure 6. Two platforms PAG lifts (701 and 702) equip a single platform attachment PAP. The invention also provides variants according to which a hooking platform (PAP) may comprise more than two PAG lifting platforms, or according to which, several PAP hooking platforms may be used for a single platform PAG elevator. The invention also provides variants according to which the PAP hooking platform is located on the surface with a PAG lift platform located beneath the surface or on the contrary an elevator platform PAG located on the surface and a PAP hooking platform located beneath the surface. area. In the case where the PAP hooking platform is located on the surface, at least a portion of the floating components of this assembly that it constitutes are located on the surface, as described in the patent document WO2015114440.
    FIG. 8 represents a cable guying cable device (801) making it possible to take up the downward pulling forces at different points of the PAP platform and thus reduce the bending forces in said platform and to balance the forces more advantageously anchoring cables with the forces exerted by the floats.
    Figure 9 illustrates a variant of the generator lift system. In this system, the cable (902) of the elevator is closed and passes through a return pulley (905) located near the bottom of the body of water. The cable is stretched with a weight (906) attached to the pulley. Two hooks (903, 904) fixed on the cable allow to hang the weights (137) which will be lowered one by one and then reassembled one by one from the bottom of the body of water.
    Winches (907) are located on the seabed in order to adapt the length of the anchoring cables and facilitate the movements of the platform of the PAG elevator.
    Propeller thrusters, not shown in the figure, may be attached to the platform of the PAG elevator or the weight (906) to make their positioning more accurate.
    Figure 10 shows a variant of the system shown in Figure 9. The return pulley (905) is attached to a movable frame (1001) mounted on driving wheels or tracks and improves the accuracy of the laying of weights (in phase of electricity production) or seizure of the weights (in phase of energy storage) of on the seabed.
    Figure 11 shows a side view, in more detail, the carriage and shows wheels (1102) for guiding the weight around the return pulley without coming into contact with said pulley. The wheels 1102 are advantageously coated on their surface with flexible and resistant materials. The figure shows a carriage mounted on wheels (1101). The invention also provides variants according to which the carriage is mounted on tracks or wheels placed on rails.
    The figure also shows fixed slings (1103) connecting the weight (135) to the hook (904). Such slings not shown in the other figures can be permanently attached to each of the weights included in the system.
    FIG. 12 shows the carriage in front view of the carriage illustrated in profile in FIG.
    Fig. 13 shows a mechanism for varying the length of the elevator cable between the PAG platform (101) and the idler pulley (905). This system makes it possible in particular to adapt the necessary length of cable when the platform PAG is not positioned vertically from the point of deposit and capture of the weights on the seabed, for example when submarine currents generate water. obliquity or curvature on the cable of the elevator or to compensate for the phenomenon of elongation or shrinkage experienced by the cable when respectively loaded or unloaded a weight. This system comprises in particular a winch (1304) connected to a pulley (1302) stretched by a weight (1301) arranged so that the elevator cable passes through all the driving pulleys (1306), by means of pulleys located on the platform PAG (1305) and by a return pulley (1302) located on the weight (1301).
    Figure 14 shows a mechanism for varying the cable length of an elevator according to a variant comprising a cable and two hoists (1401, 1402).
    FIG. 15 illustrates a variant according to which the hooks (105) are secured to the cable of the elevator (104) by means of a positioning unit (1502) and thrusters (1501) making it possible to orient the position of the hook to control its gyratory movements and horizontal translational movements. The positioning unit may include position control systems such as gyroscopes, compasses, cameras, depth meters and sonar, and power systems such as batteries or power supply cables (1504) connected to a distribution station electricity not shown in the figure and may be on the surface, below the surface or on the bottom of the water.
    FIG. 16 shows a variant of the system presented in FIG. 15, according to which the mechanism for controlling the gyratory movement is effected by fins (1601) during the ascending or descending phases. The invention may include a combination of the systems shown in Figs. 15 and 16.
    Figure 17 shows a variant according to which the hook (105) is carried by two hoists (1701,1702) positioned on either side of a beam (1703) around the axis of the hook.
    The hoists can be traversed by cables whose direction of wiring of the strands is reversed and thus reduce the global gyratory effect on the hook including on very important depths such as the oceanic depths (4000 meters).
    Figure 18 shows separate sets of pulleys (1801, 1802) for each of the two hoists shown in Figure 17. The sets of driving pulleys (1803 and 1804) can be coupled to the same gear, the same motor and the same electric generator .
    FIG. 19 illustrates a mechanism consisting of return pulleys (1902, 1903) and floats (1902) for transversely orienting the movement of the hooks of the elevator by stretching cables (1904) on either side of each hook.
    These cables make it possible to limit the rotary movements of the hooks and to partially compensate for the variation of the weight of the elevator cable portion on a hoist during the duration of an ascent or descent cycle and consequently to limit the variations of the ratio torque / power exerted on the motor and the electric generator.
