[0037] The base 12 is fixedly connected with an arc-shaped plate 11 on one side, and the arc-shaped plate 11 is provided with mounting holes on the two sides.

[0038] Specifically, the support rod three 10 and the arc-shaped plate 11 are attached to the outer wall of the wind power tower cylinder, then the bolts are passed through the mounting holes on the support rod three 10 and the arc-shaped plate 11 and screwed into the outer wall of the wind power tower cylinder, so that the support rod three 10 and the arc-shaped plate 11 are fixed on the outer wall of the wind power tower cylinder, the high-voltage connection column 2 is used for connecting the high-voltage side circuit of the transformer main body 1, the low-voltage connection column 3 is used for connecting the low-voltage side circuit of the transformer main body 1, and the installation work of the transformer main body 1 can be realized. Thus, the transformer main body 1 can be fixed again under the commonly used embedded fixing mode, the connection between the transformer main body 1 and the wind power tower cylinder is more firm, and the transformer main body 1 is not prone to loosening at the wind power tower cylinder.

[0039] In the embodiment, as shown in the figure, Figures 2-5 , Figure 7 , Figure 8 the side of the threaded block 14 is threadedly connected with a threaded rod 13, the two ends of the threaded rod 13 are rotatably arranged on the transformer main body 1, the side of the transformer main body 1 is fixedly connected with a motor two 18, and the output end of the motor two 18 is fixedly connected with one end of the threaded rod 13.

[0040] One end of each telescopic rod 15 is fixedly connected with a motor one 17, and the output end of the motor one 17 is fixedly connected with one end of the connecting plate 6.

[0041] The heat dissipation fin 5 is intermittently provided with a plurality of protrusions 30 on one side in the longitudinal direction, the receiving plate 7 is fixedly connected with a fixed column 29, the fixed column 29 is slidably connected with a reciprocating block 26, the reciprocating block 26 is rotatably provided with a connecting rod three 25 on both sides, and one end of the connecting rod three 25 is rotatably connected with one end of the push plate 22.

[0042] The fixed column 29 is sleeved with a spring two 28 on one side, one end of the spring two 28 is fixedly connected with the receiving plate 7, the other end is fixedly connected with the end of the fixed column 29, the reciprocating block 26 is fixedly connected with a transmission rod 31 on one side, and the transmission rod 31 is intermittently contacted with a plurality of protrusions 30 when moving longitudinally.

[0043] The lower end of the scraping strip 23 is fixedly connected with a spring one 27 on one side, and the end, away from the scraping strip 23, of the spring one 27 is fixedly connected with one side of the push plate 22.

[0044] Specifically, the existing transformer is used to dissipate heat from the transformer main body 1 by using the heat dissipation fin 5, but since the heat dissipation fin 5 is exposed, dust, particles and other impurities will adhere to the surface of the heat dissipation fin 5 after long-term work, which will form a layer of barrier on the surface of the heat dissipation fin 5, thereby hindering the dissipation of heat and affecting the heat dissipation effect of the transformer main body 1.

[0045] Therefore, in order to solve the above problems, in use, the collecting plate 7 in the initial state is located at the lower edge of the heat dissipation fin 5. When the transformer body 1 works for a period of time, the motor 2 18 drives the threaded rod 13 to rotate, and the threaded block 14 and the sliding block 16 slide upward. Since the scraper 23 is attached to the surface of the heat dissipation fin 5, when the scraper 23 rises, the impurities attached to the surface of the heat dissipation fin 5 will be scraped off, and the scraped impurities will fall on the surface of the collecting plate 7 until the scraper 23 moves to the upper edge of the heat dissipation fin 5, and then drives the scraper 23 to reset downward, thereby achieving the cleaning work of the impurities on the surface of the heat dissipation fin 5, thereby avoiding the situation that the impurities attached to the surface of the heat dissipation fin 5 and formed a layer of barrier on the surface of the heat dissipation fin 5, which hinders the heat dissipation and affects the heat dissipation effect of the transformer body 1. In addition, since some impurities have high hardness, such as stones and soil, such impurities may be mixed with soil and attached to the surface of the heat dissipation fin 5, and when the scraper 23 scrapes them off, they will fall downward. During the falling process, the kinetic potential energy of the impurities increases, and if the impurities are sharp and contact the surface of the heat dissipation fin 5 during the falling process, the surface of the heat dissipation fin 5 may be scratched, which not only easily causes the heat dissipation fin 5 to deform or break during subsequent use, affecting the use of the heat dissipation fin 5, but also the dust may accumulate in the scratch and cannot be easily scraped off by the scraper 23, affecting the heat dissipation performance of the heat dissipation fin 5. Therefore, in order to avoid this situation, the collecting plate 7 moves synchronously with the scraper 23, and the two always maintain a fixed distance, and the scraped impurities are collected by the collecting plate 7, thereby avoiding the situation that the impurities scraped off by the scraper 23 scratch the surface of the heat dissipation fin 5, which is beneficial to prolong the service life of the heat dissipation fin 5, and also avoids the situation that the dust accumulates in the scratch of the heat dissipation fin 5 and cannot be easily scraped off by the scraper 23, affecting the heat dissipation performance of the heat dissipation fin 5.

[0046] When the scraper 23 completes a scraping work, and the collecting plate 7 is lowered to a height where the end thereof is not attached to the surface of the transformer body 1, the motor 1 7 drives the connecting plate 6 to rotate, so that the collecting plate 7 is flipped, and the impurities on the surface of the collecting plate 7 fall off, thereby avoiding the situation that the subsequent collecting effect is affected due to too much impurities accumulated on the surface of the collecting plate 7;

[0047] Although the above-mentioned way can avoid the scratch of the fin 5 by the falling impurities, the impurities are easy to accumulate at the edge of the receiving plate 7 after sliding along the scraping strip 23, and if the volume of the impurities is too large or the number of the accumulated impurities is too much, the impurities are easy to be higher than the upper edge of the scraping strip 23, and the sharp end of the impurities can be in contact with the surface of the fin 5, at this time, if the receiving plate 7 continues to drive the impurities to rise, the sharp end of the impurities will still scratch the surface of the fin 5, so, in order to avoid this situation, the transmission rod 31 will be in intermittent contact with the plurality of protrusions 30 when the receiving plate 7 moves upward, and the transmission rod 31 will move away from the receiving plate 7 when the transmission rod 31 is in contact with the protrusions 30, at this time, the connecting rod three 25 drives the push plate 22 to slide on the limiting rod 24, and the two push plates 22 on the same receiving plate 7 move close to each other, and the impurities at the edge of the receiving plate 7 are pushed to the middle of the receiving plate 7, that is, the impurities are away from the surface of the fin 5, and the transmission rod 31 is reset under the action of the second spring 28 after passing through the protrusions 30, so that the push plate 22 pushes the impurities every time the receiving plate 7 moves a distance, thereby avoiding the situation that the impurities are accumulated at the edge of the receiving plate 7 after sliding along the scraping strip 23, the impurities are higher than the upper edge of the scraping strip 23, the sharp end of the impurities is in contact with the surface of the fin 5, the receiving plate 7 continues to drive the impurities to rise, and the sharp end of the impurities scratches the surface of the fin 5, resulting in the scratch of the surface of the fin 5, and the multiple movements of the push plate 22 are not driven by electricity, which is beneficial to save electric energy. In addition, the scraping strip 23 is always in contact with the surface of the fin 5 under the action of the first spring 27 when the push plate 22 moves to the middle of the receiving plate 7, and there will be no gap between the push plate 22 and the scraping strip 23 and the fin 5 due to the synchronous movement of the push plate 22 and the scraping strip 23 away from the inner wall of the fin 5, and the impurities will not enter the gap to affect the normal work of the push plate 22 and the scraping strip 23.

[0048] In the embodiment, as shown in the figure, Figure 6 the one side of the threaded block 14 is rotatably provided with the connecting rod one 20, one end of the connecting rod one 20 is rotatably provided with the connecting rod two 21, one end of the connecting rod two 21 is rotatably connected with one end of the telescopic rod 15, and the one side of the threaded block 14 is fixedly connected with the motor three 19, and the output end of the motor three 19 is fixedly connected with one end of the connecting rod one 20.

[0049] Specifically, when the receiving plate 7 falls by turning over to make the impurities on the surface thereof fall off, it is possible that the impurities are difficult to fall off due to strong adhesion, so, in order to avoid this situation, the connecting rod one 20 is driven to rotate by the motor three 19, and the telescopic rod 15 is driven to reciprocate under the action of the connecting rod two 21, so that the receiving plate 7 is vibrated, that is, the impurities are separated from the receiving plate 7 by vibration, thereby avoiding the situation that the subsequent use of the receiving plate 7 is affected due to the residual impurities on the surface thereof.

[0050] In the embodiment, as shown in the figure, Figure 1As shown, the upper end face of the transformer body 1 is provided with a solar panel 4.

[0051] Specifically, the solar panel 4 can convert solar energy into electric energy, and provide electric energy for the scratch-proof impurity removal assembly, so as to ensure stable and continuous operation of the scratch-proof impurity removal assembly.

[0052] Working principle: the support rod three 10 and arc plate 11 and wind power tower wall, then the bolt through the support rod three 10 and arc plate 11 on the mounting hole and spin in fixed in the wind power tower wall, namely the support rod three 10 and arc plate 11 fixed in the wind power tower wall, high voltage terminal 2 for connecting transformer main body 1 high voltage side circuit, low voltage terminal 3 for connecting transformer main body 1 low voltage side circuit, namely the installation work of transformer main body 1 is realized. Thus the transformer main body 1 in the commonly used embedded fixed mode can also be fixed, so that the transformer main body 1 and the connection of wind power tower is more firm, the transformer main body 1 is not prone to looseness in the wind power tower. The initial state of the receiving plate 7 is located at the lower edge of the fin 5. Whenever the transformer main body 1 works for a period of time, the motor two 18 drives the threaded rod 13 to rotate, so that the threaded block 14 and the sliding block 16 slide upward. Since the scraper 23 is attached to the surface of the fin 5, when the scraper 23 rises, the impurities attached to the surface of the fin 5 will be scraped off, and the scraped impurities will fall on the surface of the receiving plate 7. Until the scraper 23 moves to the upper edge of the fin 5, then drive the scraper 23 to reset downward, which can realize the cleaning work of the impurities on the surface of the fin 5, so as to avoid the situation that the impurities are attached to the surface of the fin 5 and form a layer of barrier on the surface of the fin 5, which hinders the heat dissipation and affects the heat dissipation effect of the transformer main body 1. In addition, because the hardness of some impurities is high, such as stone and soil, such impurities may be mixed with soil and attached to the surface of the fin 5. When the scraper 23 scrapes them off, they will fall down. During the falling process, the kinetic potential energy of the impurities increases continuously. If the impurities are sharp and contact the surface of the fin 5 during the falling process, it may scratch the surface of the fin 5. Not only is it easy to cause the fin 5 to deform or break in the subsequent use process, affecting the use of the fin 5, but also the dust may accumulate in the scratch, which cannot be easily scraped off by the scraper 23, affecting the heat dissipation performance of the fin 5. Therefore, in order to avoid this situation, the receiving plate 7 moves synchronously with the scraper 23, and the distance between them is always kept fixed. The scraped impurities will be received by the receiving plate 7, so as to avoid the situation that the impurities scraped off by the scraper 23 scratch the surface of the fin 5, which is conducive to prolonging the service life of the fin 5 and avoiding the situation that the dust accumulates in the scratch of the fin 5, which is difficult to be scraped off by the scraper 23, affecting the heat dissipation performance of the fin 5.When the scraper 23 completes a scraping work, and the receiving plate 7 is lowered to a height where the end thereof is not in close contact with the surface of the transformer main body 1, the motor 17 drives the connecting plate 6 to rotate, so that the receiving plate 7 is flipped, and the impurities on the surface of the receiving plate 7 fall off, thereby avoiding the case that the subsequent receiving effect is affected due to too many impurities accumulated on the surface of the receiving plate 7. Although the above-mentioned manner can avoid that the impurities scraped off scratch the fins 5, after the impurities slide along the scraper 23, the impurities are prone to accumulate at the edge of the receiving plate 7. If the volume of the impurities is too large or the number of the impurities accumulated is too much, the impurities are prone to be higher than the upper edge of the scraper 23, and the sharp end of the impurities can be in close contact with the surface of the fin 5. At this time, if the receiving plate 7 continues to drive the impurities to rise, the sharp end of the impurities will still scratch the surface of the fin 5, thereby causing the surface of the fin 5 to be scratched. Therefore, in order to avoid this case, when the receiving plate 7 moves upward, the transmission rod 31 will intermittently contact the plurality of protrusions 30. When the transmission rod 31 contacts the protrusions 30, the transmission rod 31 will move away from the receiving plate 7. At this time, the connecting rod three 25 drives the push plate 22 to slide on the limiting rod 24, so that the two push plates 22 on the same receiving plate 7 move close to each other, and the impurities at the edge of the receiving plate 7 are pushed to the middle of the receiving plate 7, that is, the impurities are away from the surface of the fin 5. After the transmission rod 31 passes through the protrusions 30, the transmission rod 31 is reset under the action of the spring two 28. Therefore, the push plate 22 pushes the impurities every time the receiving plate 7 moves a distance, thereby avoiding the case that the impurities slide along the scraper 23, the impurities accumulate at the edge of the receiving plate 7, the impurities are higher than the upper edge of the scraper 23, the sharp end of the impurities is in close contact with the surface of the fin 5, the sharp end of the impurities scratches the surface of the fin 5 when the receiving plate 7 continues to drive the impurities to rise, and the surface of the fin 5 is scratched. In addition, the multiple movements of the push plate 22 are not driven by electricity, which is conducive to saving electric energy. In addition, when the push plate 22 moves to the middle of the receiving plate 7, the scraper 23 is always in close contact with the surface of the fin 5 under the action of the spring one 27, and the gap between the push plate 22 and the scraper 23 and the fin 5 will not appear, the impurities will not enter the gap, and the normal work of the push plate 22 and the scraper 23 will not be affected. When the receiving plate 7 flips to make the impurities on the surface thereof fall off, the impurities may be difficult to fall off due to strong adhesion. Therefore, in order to avoid this case, the motor three 19 drives the connecting rod one 20 to rotate, and the telescopic rod 15 reciprocates under the action of the connecting rod two 21, so that the receiving plate 7 vibrates, thereby intensifying the impurities to separate from the receiving plate 7 by vibration, and avoiding the case that the subsequent use of the receiving plate 7 is affected due to the impurities remaining on the surface thereof. The solar panel 4 can convert solar energy into electric energy, and provide electric energy for the scratch-proof impurity removing assembly, thereby ensuring that the scratch-proof impurity removing assembly operates stably and continuously.
