Abstract
Description
Technical Field
[0001] This invention relates to the field of wind turbine technology, and more particularly to a transformer protection device. Background Technology
[0002] Transformers are important devices used to convert the electrical energy generated by wind turbines into voltage levels suitable for transmission to the power grid. Transformers are generally located in high-altitude areas, where winds are usually stronger. This is because the increased altitude leads to a decrease in atmospheric density and a greater air velocity, which in turn strengthens the wind. Strong winds in high-altitude areas can contribute to wind power generation to some extent, as higher wind speeds can improve the power generation efficiency of wind turbines.
[0003] However, strong winds at high altitudes are often accompanied by sand and gravel. This sand and gravel can directly impact the transformer, damaging its casing and, consequently, its heat dissipation fins, affecting the normal operation of the cooling system and causing equipment damage. Currently, protective covers or shields are installed around the transformer to reduce the direct entry of sand and gravel into the transformer. However, installing protective covers can affect the transformer's contact with the outside air, reducing the equipment's operating efficiency. Summary of the Invention
[0004] In view of the problems existing in the above-mentioned transformers, the present invention is proposed.

[0011] As a preferred embodiment of the transformer protection device of the present invention, the mating component includes a limiting block disposed on a rack, and a roller is rotatably disposed on the limiting block.

[0016] The beneficial effects of this invention are as follows: When there is wind, the protective components and the triggering components work together to cause some of the baffles to rotate and close, specifically blocking winds from different directions, preventing sand and gravel in the wind from damaging the transformer coating and avoiding damage to the transformer's heat dissipation fins.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.
[0027] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0028] Example 1, referring to Figures 1-3 The first embodiment of the present invention provides a transformer protection device, which includes a transformer body 100, a protection component 200 disposed on the transformer body 100, a triggering component 300 and a reset component 400 disposed on the protection component 200;
[0029] The protective component 200 includes a housing 201 disposed on the transformer body 100. The protective component 200 blocks wind from different directions to prevent sand and gravel from damaging the heat dissipation fins on the transformer body 100. The baffle 202 disposed on the housing 201 is rotated. The initial state of the baffle 202 is open, so as not to affect the contact between the transformer body 100 and the outside air.
[0030] The triggering component 300 includes a top shaft 301 disposed on the top of the housing 201, a wind plate 302 disposed on the top shaft 301, a drive assembly 303 disposed on the bottom of the top shaft 301, an adjustment assembly 304 disposed on the housing 201, and a mating assembly 305 disposed on the housing 201. When wind blows the wind plate 302 from different directions, the wind plate 302 is blown and rotates. The wind plate 302 rotates synchronously with the top shaft 301. The drive assembly 303 on the top shaft 301 drives the mating assembly 305 to work. The mating assembly 305 drives the corresponding baffle 202 to rotate and close, which specifically blocks the wind. The remaining baffles 202 always remain in the open state and will not affect the contact between the transformer body 100 and the outside air.
[0031] Furthermore, the reset component 400 includes a mounting base 401 disposed on the drive assembly 303, a fan blade 402 disposed on the mounting base 401, a release component 403 disposed on the housing 201, and a synchronization component 404 disposed on the housing 201. When the wind stops, the fan blade 402 stops rotating. The fan blade 402, in conjunction with the release component 403 and the synchronization component 404, drives the closed baffle 202 to return to the open state, so that when there is no wind, all the baffles 202 on the housing 201 remain in the open state.
[0032] During use, when wind blows from different directions, the wind vane 302 is blown and rotated. The wind vane 302 rotates synchronously with the top shaft 301. The drive component 303 on the top shaft 301 drives the cooperating component 305 to work. The cooperating component 305 drives the corresponding baffle 202 to rotate and close, specifically blocking the wind. The remaining baffles 202 remain in the open state, which does not affect the contact between the transformer body 100 and the outside air. When the wind stops, the fan blade 402 stops rotating. The fan blade 402, in conjunction with the release component 403 and the synchronization component 404, drives the closed baffle 202 to return to the open state. Thus, when there is no wind, all the baffles 202 on the outer casing 201 remain in the open state.
[0033] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the driving component 303 includes a connecting plate 303a disposed on the top shaft 301, a sliding groove 303b disposed in the connecting plate 303a, a slidable actuating plate 303c disposed on the sliding groove 303b, and a spring 303d disposed on the corresponding surface of the actuating plate 303c and the sliding groove 303b. The elasticity of the spring 303d drives the actuating plate 303c to reset. When the top shaft 301 rotates, the top shaft 301 drives the connecting plate 303a to rotate, and the actuating plate 303c on the connecting plate 303a drives the cooperating component 305 to work, so that the baffle 202 can specifically block the wind from different directions.
[0034] Furthermore, the connecting plate 303a is slidably disposed on the top of the housing 201, and the housing 201 is configured as a hollow shape. The hollow shape of the housing 201 reduces the weight of the housing 201 and does not affect the normal operation of the transformer body 100.
[0035] Furthermore, the adjustment assembly 304 includes a rotating shaft 304a rotatably mounted on the housing 201, a baffle 202 mounted on the rotating shaft 304a, a gear 304b mounted on the rotating shaft 304a, and a rack 304c slidably mounted on the housing 201. The gear 304b and rack 304c mesh with each other, and a torsion spring 304d is connected to the corresponding surface of the gear 304b and the housing 201. When the actuating plate 303c rotates and presses the rack 304c, the rack 304c slides and engages with the gear 304b, driving the gear 304b to rotate. The gear 304b drives the rotating shaft 304a to rotate synchronously, and the rotating shaft 304a drives the baffle 202 to rotate and close. When the actuating plate 303c does not engage with the rack 304c, the elasticity of the torsion spring 304d drives the rotating shaft 304a to reset, causing the baffle 202 to rotate and unfold.
[0036] Furthermore, multiple baffles 202 are provided, and the multiple baffles 202 are distributed in a circumferential array on the outer shell 201. The outer shell 201 is provided with rectangular grooves 203 that cooperate with the baffles 202. The rectangular grooves 203 provide conditions for the rotation of the baffles 202, and the circumferential array arrangement allows the baffles 202 to specifically block wind from different directions.
[0037] Furthermore, the mating component 305 includes a limiting block 305a disposed on the rack 304c, and a roller 305b rotatably disposed on the limiting block 305a. When the actuating plate 303c rotates, it will press against the roller 305b, thereby reducing the friction of the actuating plate 303c. The limiting block 305a limits the gear 304b and prevents the rack 304c from slipping.
[0038] Furthermore, the mating component 305 also includes a guide groove 305c disposed on the housing 201. The rack 304c and the bottom of the limiting block 305a are connected to a guide block 305d. The guide block 305d is slidably disposed in the guide groove 305c and guides the rack 304c through the guide groove 305c. When the rack 304c slides, the guide block 305d will slide along the guide groove 305c. When it slides to the bottom of the sliding groove 303b, the limiting block 305a limits the gear 304b.
[0039] The remaining structure is the same as that in Example 1.
[0040] During use, when the top shaft 301 rotates, it drives the connecting plate 303a to rotate. The jacking plate 303c on the connecting plate 303a presses the roller 305b. The roller 305b drives the limiting block 305a and the rack 304c to slide synchronously along the guide groove 305c. The rack 304c slides and drives the gear 304b to rotate. The gear 304b drives the rotating shaft 304a to rotate. The rotating shaft 304a drives the baffle 202 to rotate and close, which specifically blocks the wind from different directions. All the baffles 202 located in the jacking area of the jacking plate 303c are closed.
[0041] Example 3, referring to Figures 1-6 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the release component 403 includes a drive shaft 403a rotatably mounted on a mounting base 401. The mounting base 401 is mounted on a connecting plate 303a. The fan blade 402 is mounted on the drive shaft 403a. A second torsion spring 403b is mounted on the outside of the drive shaft 403a. The two ends of the second torsion spring 403b are respectively connected to the corresponding surfaces of the fan blade 402 and the mounting base 401. When there is wind, the fan blade 402 rotates, and the drive shaft 403a on the fan blade 402 rotates synchronously. The second torsion spring 403b on the fan blade 402 stores energy.
[0042] Furthermore, the mounting base 401 is fan-shaped, and a receiving cavity is provided inside the mounting base 401. The fan blade 402 does not contact the receiving cavity. By setting the mounting base 401 to a fan shape, the wind on one side of the fan blade 402 is blocked, so that the fan blade 402 can only rotate in one direction.
[0043] Furthermore, the synchronization component 404 includes an inlet / outlet hole 404a provided on the mounting base 401, an arc-shaped groove 404b provided on the connecting plate 303a, the arc-shaped groove 404b communicating with the inlet / outlet hole 404a, a release roller 404c provided on the drive shaft 403a, a rope 404d wound on the release roller 404c, the other end of the rope 404d being connected to the actuating plate 303c, and the rope 404d slidingly disposed on the inlet / outlet hole 404a and the arc-shaped groove 404b, so that when there is wind... When the fan blade 402 rotates, it drives the torsion spring 403b to store energy. The transmission shaft 403a rotates synchronously with the fan blade 402, and the release roller 404c on the transmission shaft 403a rotates synchronously. The release roller 404c releases the rope 404d, so that the rope 404d does not pull the top plate 303c. Then, the spring 303d squeezes the top plate 303c, driving the top plate 303c to be in an unfolded state. The unfolded state of the top plate 303c can drive the rack 304c to slide.
[0044] The remaining structure is the same as that in Example 2.
[0045] Working principle
[0046] In use, when wind blows from different directions, the wind vane 302 is blown and rotates. The wind vane 302 rotates synchronously with the top shaft 301, and the connecting plate 303a on the top shaft 301 rotates synchronously. The pushing plate 303c on the connecting plate 303a presses the roller 305b, causing the limiting block 305a and the rack 304c to slide synchronously along the guide groove 305c. The rack 304c slides and drives the gear 304b to rotate. The gear 304b drives the rotating shaft 304a to rotate, and the rotating shaft 304a drives the baffle 202 to rotate and close, specifically blocking wind from different directions. Only the baffle 202 corresponding to the area pressed by the pushing plate 303c closes. At the same time, the wind drives the fan blade 402 to rotate, and the fan blade 402 drives the torsion spring 403b to store power. The transmission shaft 403a rotates synchronously with the fan blade 402, and the release roller 404c on the transmission shaft 403a rotates synchronously, releasing... The release roller 404c releases the rope 404d, preventing the rope 404d from pulling the top plate 303c. The spring 303d then compresses the top plate 303c, causing it to be in an unfolded state. When there is no wind, the fan plate 302 and the fan blade 402 stop rotating. The elasticity of the second torsion spring 403b drives the release roller 404c to rewind, pulling the rope 404d. The rope 404d pulls the top plate 303c, causing it to slide along the sliding groove 303b, closing the top plate 303c and preventing it from contacting the roller 305b. The elasticity of the first torsion spring 304d then resets the rotating shaft 304a, causing the closed baffle 202 to rotate and unfold. Thus, when there is no wind, all the baffles 202 are in an unfolded state, without affecting the contact between the transformer body 100 and the outside air.
