    TECHNICAL FIELD The present invention relates to a device for removing snow and ice on power lines.
    Background of the invention During the winter months, there are problems in the northern parts of the world with snow and ice accumulating on power lines and weighing them down, which leads to loss of voltage and in the worst case to the lines breaking. Today, snow and ice are removed manually by blows with an insulating stick on the leads. This is very time consuming and expensive, as it is difficult to get to the lines because they are located in an often inaccessible terrain. Also exposes personnel who are to loosen the snow and ice to a great danger due to the risk of overturning from the power lines. The snow can also be removed by flying around the lines with a helicopter and letting the wind from the rotor blades blow away the snow. This too is a very time consuming and expensive method.
    SUMMARY OF THE INVENTION The object of the present invention is to provide a device for removing snow and ice from power lines which is simple, inexpensive and safe. Furthermore, the device should be easy to install and require some maintenance work.
    The device must also be able to be used for preventive maintenance of diversions to remove snow, ice and water from the pipelines at an early stage before more severe ice formation has formed.
    This is achieved according to the present invention by a device for removing snow and ice on power lines, which device comprises a rigid body comprising a first fastening portion and a second fastening portion, the first fastening portion vibrating rigidly supporting a vibrating motor and a post bracket for suspending the device on a post . The second mounting portion carries vibration damping a control unit which is arranged to communicate with the vibration motor.
    The term vibration rigid in this respect means that the vibrations generated by the vibration motor are allowed to propagate from the body to the post with as little energy loss as possible. This is to get an efficient removal of snow, ice or water from the pipes carried by the pole.
    The device according to the invention is simple and inexpensive to manufacture, since the frame can be made of, for example, a plate of steel which is then bent so that the two different fastening portions are formed. It can also be cut from a single-extruded profile. The device can be easily installed on a power line post and does not require much maintenance as the device can be fastened around a post via a post bracket which is clamped to the post. The device can be arranged to be activated if necessary, for example after snowfall or in connection with weather changes, when there is a risk of ice formation. The latter is an example of preventive maintenance. This does not make it necessary for a person to tread through difficult terrain to the power line and manually beat away snow and ice. This increases the safety of service personnel and saves costs for both personnel and transport to the power line. Furthermore, you can also avoid voltage drops and unnecessary stress on the power lines after the snow and ice do not weigh down the power lines for a long time.
    The first and the second fastening portion may be perpendicularly arranged in relation to each other. As a result, the vibrations generated from the vibration motor will mainly propagate in one direction and in this way the stress on the control means and above all the electronics in this control means can be reduced.
    The first fastening portion, when the device is mounted on a single post, may be arranged to extend parallel to the longitudinal axis of the post. This means that generated vibrations from the vibration motor are transmitted to the pole along its length and thus can further be transmitted to the power lines at the top of the pole so that snow and ice are shaken loose.
    The vibration motor can be rotatably attachable relative to the first attachment portion of the frame and the longitudinal axis of the post. In this way, the post can in vibration obtain a movement which can most closely be described as a vibrating and circulating movement which contributes to improved effect.
    The post bracket may have a first and a second, spaced apart brackets, which are intended to engage the post at two mutually different heights. As a result, the clamping force on the post will be less and the post attachment will be more stable compared to if you only have one attachment point. This can also be compared with if you had had more than two attachment points. When attaching at three different heights, for example, the stability of the attachment will be affected more by the cross section of the post and more unstable attachment compared to two attachments. The device according to the invention is particularly intended for round posts of round timber, which means that each post has a unique cross-section and dimension seen along its length. The post bracket according to the invention allows a very simple adaptation of the attachment to the individual post.
    In said device the vibrating motor can be fastened to the first fastening portion by means of a plurality of fastening means, at least one first of these plurality of fastening means, in mounted condition, being arranged at the same height as the first fastening and at least a second of these plurality of fastening means, in mounted condition, being arranged at the same height as the other bracket. As a result, the vibrations generated will propagate via the fastening means directly to the brackets and thus to the post. In this way a more efficient shaking of the power lines is obtained without unnecessary energy losses.
    In said device, furthermore, at least one damper can be arranged between the second fastening portion and the control unit. By arranging a single damper, for example an elastic damper in the form of a rubber ring, the intermediate control unit and the second fastening portion, the risk of vibrations being transmitted to the control unit and destroying the electronics therein is reduced.
    In said device, each of the brackets of the post bracket may comprise a first recessed portion which is arranged at the first fastening portion and which is arranged to abut against a first side of the post, and a second recessed portion which is arranged to abut against a second, relative to the first , opposite side of the post, and a clamping means arranged to pull the first and the second recessed portion in the direction of each other. Furthermore, it is easy to install and maintain the device on a pole.
    The control unit can be intended to be remotely controlled via mobile communication. In this way, the control unit can be activated by decision at a central location during a change in the weather or when a weather forecast warns of snow / rain. The remote control can also be triggered by local sensors that sense the thickness of snow or ice on the power line. An example of such a sensor is a solar cell that senses any snow cover. Because the device can be remotely controlled, it is possible to avoid having to remove ice and snow manually. This leads to increased safety and reduced costs when you do not have to get to the power line, ie. long distances in hard-to-reach terrain.
    According to another aspect, the invention relates to a use of the device according to the invention for removing snow and ice on power lines.
    In order to avoid unnecessary repetition, reference is made to the above discussion of the advantages of the device according to the invention.
    Brief Description of the Drawings The above features and advantages of the present invention will be explained by the following illustrative but non-limiting detailed description of an embodiment of the present invention with reference to the accompanying drawings.

    Fig. 2 shows the device according to Fig. 1 in mounted condition on a circular power line pole.
    Fig. 3 shows the device according to Fig. 1 seen from the side.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The invention will now be described in accordance with how the device is intended to be attached to a vertical, round power line post in accordance with Figure 2. The power line post may, for example, be a post of wood, composite or concrete. The device according to the invention is particularly intended for round posts of round timber, which means that each post has a unique cross-section and dimension seen along its length.
    In its simplest embodiment, the device comprises a frame 2, which is intended to be attached to a post 16 by means of a post bracket 8 and where the frame 2 supports a vibration motor 6 and a control unit 10.
    Referring now to Fig. 1, the body 2 comprises a first 4a and a second fastening portion 4b which are arranged perpendicularly relative to each other. The first fastening portion 4a carries a vibration motor 6 and a post bracket 8 for suspending the device on a post 16. The vibration motor 6 and the post bracket 8 are arranged on mutually opposite sides of the first fastening portion 4a.
    The second fastening portion 4b carries a control unit 10 which is intended to communicate with the vibration motor 6.
    The mounting portions 4a, 4b of the frame 2 form two legs. In accordance with fig. 1-3, the frame 2 is rigid and made in one piece of eg steel which has been bent to form the two mutually perpendicular fastening portions 4a, 4b. The frame can also be made of a cut extruded angle profile. for example, the frame 2 can be made of two different plates, one for each fastening portion 4a, 4b, which are then joined together by welding. These plates can be made of a material with the same self-damping ability or of two materials with different self-damping ability. The self-damping contributes to a vibration-rigid construction of the frame. It is understood that the frame can also be made of, for example, composite.
    As can be seen from the figures, the vibration motor 6 is fastened to the first fastening portion 4a on one side opposite the post bracket 8. The fastening is made by means of a plurality of fastening means 12, such as bolts.
    As can be seen from the figures, the vibration motor 6 will thus hang parallel to the plane of expansion of the second fastening portion 4b when the device is fixed around a post 16. The vibrating motor 6 has no direct contact with the second fastening portion 4b.
    The vibration motor 6 comprises an associated junction box 14 with a socket for eg 220V for power supply. The power can be taken from an external power source or directly from the power line.
    A post bracket 8 is mounted on the first mounting portion 4a opposite side of the vibration motor 6. The post bracket 8 is intended to be mounted on a round power line post 16 so that the plane of extension of the first mounting portion 4 extends parallel to the longitudinal axis of the post 16, as shown in Figure 2. propagate via the post 16 the power lines and shake off snow and ice in a satisfactory manner the post post bracket 8 is arranged around the upper part of the post 16, in the vicinity of the power lines. However, those skilled in the art will recognize that other attachment positions may be possible.
    The post bracket 8 comprises two brackets 18, 20 which are intended to fasten the circumferential post 16 at two mutually different heights. Respective bracket 18, 20 in this exemplary embodiment consists of two recessed portions 18a, 18b; 20a, 20b, which are intended to grip the post 16 on opposite sides thereof.
    The first recessed portions 18a, 20a are intended to be fastened to the first fastening portion 4a, i.e. on the opposite side the vibration motor 6. More specifically, the fastening means 12 of the vibrating motor 6 are advantageously arranged so that at least one first of the vibrating motor 6 fastening means 12 is arranged at the same height 18 also that at least one second of the fastening means 12 of the vibration motor 6 is arranged at the same height as the second bracket 20.
    Vibrations from the vibration motor 6 will thus be transmitted to the post bracket 8 directly and thus to the post 16 without unnecessary energy losses. This gives an even distribution of vibrations and thus shaking of the post compared to if the vibration motor 6 would be attached at a different height than the mounts 18, 20 of the post bracket 8.
    In the embodiment shown, the recessed portions 18a, 18b, 20a, 20b are designed as inclined legs which have a recess between them in order to be able to enclose the post 16. The recess can e.g. have the shape of a V, a U or a radius seen along the longitudinal axis of the post. The design of the legs In the embodiment shown, the recessed portions 18a, 18b, 20a, 20b consist of two identical V-shaped parts which have been mounted parallel to each other in the longitudinal direction of the post. These parts form a fastening for a clamping member 24. The two parts of the second recessed portion 18b, 20b have been joined together by means of a bracket 22 to obtain a stability.
    In the embodiment shown, the clamping member 24 comprises four tension bolts which extend between the recessed portions 18a, 18b; 20a, 20b of the brackets 18, 20. The clamping means 24 is arranged to pull the two recessed portions 18a, 18b, 20a, 20b towards each other for fastening the post bracket 8 around the post 16.
    It will be appreciated that the clamping member 24 may be formed in a variety of ways. In an embodiment not shown, the clamping means may comprise, for example, a hinge which holds together one side of the bracket 18, 20 while a tension bolt is arranged on the opposite side. In this way, the bracket 18, 20 can be folded around the post 16 and then pulled around the post 16 by means of the tension bolt.
    Referring to Fig. 4, an example is shown of how the first mounting portion 4a of the body 2 may be designed to allow different mounting positions for the pre-vibration motor 6. In the embodiment shown, the first mounting portion 4a is provided with four arcuate long holes 50 for passing the mounting means 12 used for mounting After the insertion of the fastening means 12 in the long holes 50, the vibration motor 6 is rotated relative to the fastening portion 4a to the desired inclination relative to the longitudinal axis of a post by the fastening means 12 being guided by the long holes 50. Thereafter the fastening means The longitudinal axis of the vibration motor 6 relative to the post of the post may, for example, be in the order of 5-20 degrees. Due to an inclination, the post can obtain movement that can almost be described as a vibrating and circulating movement, which contributes to improved effect.
    Now with new reference to Figures 1 and 3, a control unit 10 is attached to the second attachment portion 4b. According to the embodiment of Figure 1, the control unit 10 is mounted on the body 2 and more specifically on the side of the second fastening portion 4b which is turned away from the vibration motor 6.
    The control unit 10 is preferably vibration damping attached to the second mounting portion 4b. This can be achieved by arranging a damper 28 between the control unit 10 and the second fastening portion 4b, as can be seen from Fig. 3. The damper 28 can be made of an elastic material, e.g. rubber and have the shape of a rug or pillow. The damper 28 can also be constituted by a spring. The damping can also be achieved in that the second fastening portion 4b is made of a material with a different self-damping than the material of the first fastening portion 4a.
    The control unit 10 can be operated by means of rechargeable batteries, where the charging can take place by means of, for example, solar cells. The control unit 10 can also be operated by means of a power supply from the power line.
    The control unit 10 is intended to communicate and control the vibration motor 6 and can be remotely controlled by mobile communication. This communication may be using a GPRS, 3G or GPS modem 26. This modem 26 may be attached to the second mounting member 4b on the same side as the controller 10 to avoid vibration destroying the electronics.
    Sensors (not shown) may be connected to the control unit 10 for control when the control unit is to communicate with the vibration motor 6 and initial vibrations. An example of such a sensor is a solar cell which, when covered with snow or ice, gives a signal to the control unit 10 to start the vibration motor 6 so that vibrations are generated. Furthermore, a sensor on the power line could sense how much the line is being pushed down by snow and ice. If the depression exceeds a certain threshold value, the sensor sends a signal to the control unit 10. This is only an example of how sensors and those skilled in the art can be used that there are other possible solutions and the invention should not be limited to these examples.
    In the following, the function and thus the use of the device 1 according to the invention will be described. The example assumes that the device is intended to be remotely controlled via the mobile telephone network.
    From a central location, for example triggered by a weather forecast indicating snowfall, the control unit 10 is instructed via the mobile telephone network to start the vibration motor6. The vibration motor 6 starts and generates vibrations. The vibrations propagate through the vibration-rigid fastening portion 4a to the post bracket 8 via the fastening means 12, the vibrations spreading to the recessed portions 18a, 18b; 20a, 20b on each side of the post 16. The vibrations propagate to the post 16 which begins to vibrate, which in turn leads to the power line vibrating with the result that snow and ice are shaken off. The control unit 10 can be programmed to drive the vibration motor 6 for a limited period of time of eg 5-60 seconds. It is understood that this time period is an example and can be varied depending on the current situation. The control unit 10 can also be programmed to interval control the vibration motor 6 so that it is in operation for a first period of time and is then temporarily switched off and then restarted. This can be repeated in the desired number of repetitions.
    Those skilled in the art will appreciate that the described embodiment may be varied within the scope of the appended claims. For example, the device post attachment may have a different one than the embodiment shown. Furthermore, in order to obtain a cost-effective solution, the device can be attached to the second line post 16 or locally to the line posts 16 which are located in locations where a lot of snow and ice is formed or where there is very difficult terrain.
