Description

Technical Field

[0001] The present invention relates to the field of wind power transformers, and particularly to a wind power transformer with good waterproof performance. Background Art

[0002] As a key device in a wind power generation system, a wind power transformer is responsible for stepping up or stepping down the electric energy generated by a wind turbine to meet the requirements of grid connection and transmission. A wind power transformer is usually installed in an outdoor environment and directly exposed to various weather conditions. Especially when facing extreme weather such as heavy rain and typhoon, its operation stability and safety still need to be ensured.

[0003] For an external transformer, a suitable core diameter is selected for manufacturing products according to the costs of core silicon steel sheets and winding copper wires, and the cost is reduced on the premise of meeting technical parameters; high- and low-voltage switch cabinets can be arranged on the same horizontal plane as the transformer body and placed in a large housing, which is convenient for manufacturing, transportation, hoisting, on-site installation and future maintenance; the cooling method adopts AN / AF, and the fan is placed below the transformer body, with a simple cooling method, high cooling efficiency and low cost.

[0004] However, traditional wind power transformers have a certain degree of waterproof performance. However, in extreme weather with heavy precipitation such as heavy rain, traditional waterproof measures often fail to completely block the intrusion of a large amount of rainwater, resulting in rainwater invading the interior of the transformer, causing short circuits and corrosion of electrical components, affecting the performance of the wind power transformer. Moreover, rainwater may invade the interior of the transformer through the gaps between the doors, and impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in insulation resistance, and further reducing the insulation performance of the transformer, which may pose a safety hazard for subsequent workers to open the door for equipment maintenance or repair.

[0005] Therefore, we propose a wind power transformer with good waterproof performance. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve the problems that traditional waterproof measures often fail to completely block the intrusion of a large amount of rainwater and rainwater may invade the interior of the transformer through the gaps between the doors, a wind power transformer with good waterproof performance is proposed.

[0007] To achieve the above object, the present invention provides the following technical solution: a wind power transformer with good waterproof performance, including a wind power transformer main body, a transformer box top cover is arranged at the top of the wind power transformer main body, water receiving grooves are symmetrically opened on the surface of the transformer box top cover, water inlet grooves are opened at the bottom ends of the two water receiving grooves, a water flow groove is opened at the bottom end of the water inlet groove, a first water receiving square pipe is fixedly connected to the bottom end of the transformer box top cover, the water flow groove inside the transformer box top cover is communicated with the groove in the first water receiving square pipe, a base is fixedly connected to the bottom end of the first water receiving square pipe, and a closing component for closing the ventilation fan window is arranged on one side of the first water receiving square pipe;

[0008] The closing component includes a second water receiving square pipe fixedly connected to one side of the first water receiving square pipe, a water receiving groove is opened inside the second water receiving square pipe, a communication port is opened on the surface of one side of the first water receiving square pipe, the groove inside the first water receiving square pipe is communicated with the water receiving groove inside the second water receiving square pipe through the communication port, a piston is slidably connected to the outer wall of the water receiving groove, a sliding rod is fixedly connected to the top end of the piston, a limiting block is slidably connected to the outer wall of the sliding rod, a linkage block is arranged at the top end of the limiting block, the linkage block is fixedly connected to the outer wall of the sliding rod, a connecting rod is fixedly connected to one side of the linkage block, a first rack is fixedly connected to one side of the connecting rod, and a ventilation component is arranged on one side of the first rack; It avoids the problem that although the traditional wind power transformer has certain waterproof performance, in extreme weather, such as heavy rain or continuous heavy precipitation, its waterproof ability may be affected to a certain extent, resulting in rainwater invading the inside of the transformer, causing short circuits and rust of electrical components and affecting the performance of the wind power transformer. It improves the waterproof performance of the wind power transformer, reduces the invasion of rainwater into the inside of the transformer, and further improves the service life of electrical components, ensuring the normal operation of the wind power transformer in extreme weather with large precipitation such as heavy rain.

[0009] Preferably, the ventilation component includes a linkage rod fixedly connected to one side of the first rack, a second rack is fixedly connected to one side of the linkage rod, gears are evenly meshed with both the second rack and the first rack close to the wind power transformer main body, rain shields are fixedly connected to one ends of the gears, and a rain shielding component is arranged on one side of the first water receiving square pipe; Conducting both sides simultaneously helps to quickly protect the inside of the transformer in case of emergencies such as heavy rain.

[0010] Preferably, the rain shield assembly includes a chute rod disposed on one side of the first water receiving square pipe. A fixing block is fixedly connected to the top end of the chute rod. A motor is fixedly connected to the inner wall of the fixing block. A roller is fixedly connected to the outer wall of the output shaft of the motor. A rain shield is sleeved on the outer wall of the roller. A sliding rod is fixedly connected to the lower surface of the rain shield. Limiting rods are fixedly connected to both ends of the sliding rod; this avoids rainwater from invading the interior of the transformer through the gaps between the doors. Impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in the insulation resistance, and further reducing the insulation performance of the transformer, which may pose a safety hazard problem for subsequent staff to open the door for equipment maintenance or repair. It improves the waterproof performance of the wind power transformer, ensures the insulation performance of the equipment and the safety of the staff.

[0011] Preferably, a bent pipe is fixedly connected to the inner wall of the bottom end of the first water receiving square pipe. One end of the bent pipe passes through the base and extends to the bottom end of the base. The distance from the other end of the bent pipe to the top end of the base is less than the distance from the top end of the communication port to the top end of the base; this avoids the problem that when the rainwater in the first water receiving square pipe does not push the sliding rod, that is, the sliding rod does not drive the gear and the rain shield to rotate to block the ventilation opening, and the rainwater flows in and out at the same time, slowing down the start of the closing assembly, and thus affecting the waterproof ability of the device. It improves the reliability of the device. First, the rainwater flows in to start the closing assembly, and then it flows out, accelerating the start of the closing assembly and improving the waterproof performance of the wind power transformer.

[0012] Preferably, the cross-section of the water flow trough is set as an inclined plane; the flowing rainwater in the water flow trough is used for heat dissipation, reducing the increase in internal temperature caused by the blockage of the ventilation opening.

[0013] Preferably, a water outlet is opened on the side of the first water receiving square pipe away from the main body of the wind power transformer. The water outlet is opened at the top part of the first water receiving square pipe. The maximum length from one end of the water outlet to the top end of the first water receiving square pipe is greater than the minimum length from the surface of the bent pipe to the top end of the first water receiving square pipe; this avoids the problem that rainwater accumulates in the water flow trough, and the top cover of the transformer box body receives more gravity, resulting in increased wear of the top cover of the transformer box body. It improves the drainage efficiency and extends the service life of the equipment.

[0014] Preferably, a first chute is opened on the surface of the chute rod. A second chute is opened on one side of the first chute. The sliding rod is slidably connected to the outer wall of the first chute. The limiting rod is slidably connected to the outer wall of the second chute; this avoids the problem that the wind blows the rain shield, causing the rain shield to flutter and affecting the rain shielding ability of the rain shield. It improves the waterproof performance of the wind power transformer and effectively covers and protects the transformer from rain.

[0015] Preferably, the diameter of the inner groove of the first water receiving square pipe is larger than the diameter of the water receiving trough; this enables the rainwater in the water receiving trough to exert a greater thrust on the piston, improving the reliability of the device.

[0016] Preferably, the cross-section of the rain shield is set in a "Z" shape, the lengths extending from both sides of the rain shield are equal, and the maximum length between the upper and lower ends of the rain shield is twice the minimum length between the upper and lower ends of the rain shield; effectively blocking the intrusion of rainwater and improving the waterproof performance of the wind power transformer.

[0017] Preferably, a button is arranged above the sliding rod, and the button is arranged on the surface of the top cover of the transformer box body; while blocking the ventilation opening, the rain shield is lowered to prevent rainwater from invading the transformer interior through the gap between the doors, and this double protection greatly improves the waterproof performance of the transformer in extreme weather.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Through the provided closing assembly, when the wind power transformer is in extreme weather with large precipitation such as heavy rain, rainwater flows into the first water collecting square pipe, and then by using the principle of communicating vessels, the rainwater flows into the second water collecting square pipe to push the piston and the sliding rod to move upward. The sliding rod drives the first rack to move upward through the linkage block and the connecting rod. During the movement of the first rack, the gear and the rain shield are driven to rotate upward through meshing to block the ventilation opening. At the same time, the movement of the first rack drives the connecting rod to move, the movement of the connecting rod drives the second rack to move, and the second rack drives the rain shield on the other side to rotate and block the ventilation opening, avoiding the problem that although the traditional wind power transformer has certain waterproof performance, in extreme weather such as heavy rain or continuous heavy precipitation, its waterproof ability may be affected to a certain extent, resulting in rainwater invading the transformer interior, causing short circuits and corrosion of electrical components, and affecting the performance of the wind power transformer. It improves the waterproof performance of the wind power transformer, reduces the intrusion of rainwater into the transformer interior, and further improves the service life of electrical components, ensuring the normal operation of the wind power transformer in extreme weather with large precipitation such as heavy rain.

[0020] 2. Through the provided rain shielding assembly, when the wind power transformer is in extreme weather with large precipitation such as heavy rain and rainwater flows into the second water collecting square pipe to push the piston and the sliding rod to move upward, the sliding rod presses the button, and the button controls the motor to be powered on. The output shaft of the motor rotates to drive the roller to rotate, and the rotation of the roller causes the rain shield to rotate and extend. The sliding rod slides downward in the first chute by gravity and pulls the rain shield. After the motor rotates a set number of turns and stops, the sliding rod reaches the lowest point, avoiding the problem that rainwater may invade the transformer interior through the gap between the doors, and impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in insulation resistance, and further reducing the insulation performance of the transformer, which may pose a safety hazard problem for subsequent staff to open the door for equipment maintenance or repair. It improves the waterproof performance of the wind power transformer, ensures the insulation performance of the equipment and the safety of the staff.

[0021] 3. Through the provided elbow pipe, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain and rainwater flows into the first water-receiving square pipe, the height of the rainwater does not exceed the bending point of the elbow pipe, and the rainwater in the first water-receiving square pipe will not flow out. When the height of the rainwater exceeds the bending point of the elbow pipe, due to the siphon effect, the rainwater flows in from one end of the elbow pipe and flows out from the elbow pipe until the liquid level is lower than the end of the elbow pipe farther from the ground. This avoids the problem that when the rainwater in the first water-receiving square pipe flows in and out without pushing the sliding rod (i.e., the sliding rod does not drive the gear and the rainshield to rotate to block the ventilation opening), it slows down the startup of the closing component, thereby affecting the waterproof ability of the device, improving the reliability of the device. First, it flows in to start the closing component, and then it flows out, accelerating the startup of the closing component and improving the waterproof performance of the wind power transformer.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 9 , in the figure, a wind power transformer with good waterproof performance includes a main body 1 of the wind power transformer. A top cover 2 of the transformer box is provided at the top of the main body 1 of the wind power transformer. Water receiving troughs 3 are symmetrically opened on the surface of the top cover 2 of the transformer box. A water inlet trough 17 is opened at the bottom of the two water receiving troughs 3. A water flow trough 18 is opened at the bottom of the water inlet trough 17. A first water storage square pipe 4 is fixedly connected to the bottom of the top cover 2 of the transformer box. The water flow trough 18 inside the top cover 2 of the transformer box is communicated with the trough in the first water storage square pipe 4. A base 32 is fixedly connected to the bottom of the first water storage square pipe 4. A closing assembly for closing the ventilation fan window is provided on one side of the first water storage square pipe 4;

[0035] The closing assembly includes a second water storage square pipe 6 fixedly connected to one side of the first water storage square pipe 4. A water storage trough 10 is opened inside the second water storage square pipe 6. A communication port 5 is opened on the surface of one side of the first water storage square pipe 4. The trough inside the first water storage square pipe 4 is communicated with the water storage trough 10 inside the second water storage square pipe 6 through the communication port 5. A piston 7 is slidably connected to the outer wall of the water storage trough 10. A slide bar 8 is fixedly connected to the top of the piston 7. A limit block 9 is slidably connected to the outer wall of the slide bar 8. A linking block 31 is provided at the top of the limit block 9. The linking block 31 is fixedly connected to the outer wall of the slide bar 8. A connecting rod 11 is fixedly connected to one side of the linking block 31. A first rack 12 is fixedly connected to one side of the connecting rod 11. A ventilation assembly is provided on one side of the first rack 12.

[0036] In this embodiment: Through the provided closing component, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, rainwater flows into the first water collecting square pipe 4, and then, using the principle of communicating vessels, the rainwater flows into the second water collecting square pipe 6, pushing the piston 7 and the sliding rod 8 to move upward. The sliding rod 8 drives the first rack 12 to move upward through the linkage block 31 and the connecting rod 11. During the movement of the first rack 12, the gear 13 and the rain shield 14 are driven to rotate upward through meshing, blocking the ventilation opening. At the same time, the movement of the first rack 12 drives the linkage rod 15 to move, and the movement of the linkage rod 15 drives the second rack 16 to move. The second rack 16 drives the rain shield 14 on the other side to rotate and block the ventilation opening. This avoids the problem that although traditional wind power transformers have a certain waterproof performance, in extreme weather such as heavy rain or continuous heavy precipitation, their waterproof ability may be affected to a certain extent, resulting in rainwater invading the interior of the transformer, causing short circuits and corrosion of electrical components and affecting the performance of the wind power transformer. It improves the waterproof performance of the wind power transformer, reduces the intrusion of rainwater into the interior of the transformer, and thus extends the service life of electrical components, ensuring the normal operation of the wind power transformer in extreme weather with heavy precipitation such as heavy rain.

[0037] Please refer to Figure 3 and Figure 4 As shown in the figure, the ventilation component includes a linkage rod 15 fixedly connected to one side of the first rack 12. One side of the linkage rod 15 is fixedly connected to a second rack 16. The second rack 16 and the side of the first rack 12 close to the wind power transformer main body 1 are evenly meshed with gears 13. One end of each gear 13 is fixedly connected to a rain shield 14. A rain shielding component is provided on one side of the first water collecting square pipe 4.

[0038] In this embodiment: Through the provided ventilation component, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, the first rack 12 moves upward to drive the rain shield 14 to rotate. The first rack 12 then drives the second rack 16 to move through the linkage rod 15, and the second rack 16 drives the rain shield 14 on the other side to rotate, blocking both ventilation openings. Blocking both sides simultaneously helps to quickly protect the interior of the transformer in an emergency such as heavy rain.

[0039] Working principle: The wind power transformer is in extreme weather with heavy precipitation such as heavy rain;

[0040] Rainwater slides down from the top cover 2 of the transformer box body and falls into the water receiving troughs 3 on both sides. Then, it flows into the flowing trough 18 from the two water receiving troughs 3 through the water inlet trough 17 respectively. The rainwater entering from the water receiving trough 3 on the side far from the rain shield 24 flows through the flowing trough 18 which is inclined, moves to the side close to the rain shield 24, forms a rainwater confluence, and flows into the first water storage square pipe 4. The first water storage square pipe 4 and the second water storage square pipe 6 form a communicating vessel through the communication port 5, so that the water surface heights of the rainwater in the first water storage square pipe 4 and the second water storage square pipe 6 are the same. As the rainwater flows in, the rainwater in the second water storage square pipe 6 pushes the piston 7 to move upward. The piston 7 pushes the sliding rod 8 to move upward. The sliding rod 8 drives the linkage block 31 to move upward. The linkage block 31 drives the connecting rod 11 to move upward. The connecting rod 11 drives the first rack 12 to move upward. During the upward movement of the first rack 12, it drives the gear 13 to rotate through meshing. The rotation of the gear 13 drives the rain shield 14 to rotate upward. One end of the lower rain shield 14 rotates in cooperation with one end of the upper rain shield 14 to block the ventilation opening. The movement of the first rack 12 drives the linkage rod 15 to move. The movement of the linkage rod 15 drives the second rack 16 to move. Similarly, the second rack 16 drives the rain shield 14 on the other side to rotate and block the ventilation opening.

[0041] During the upward movement of the sliding rod 8, it presses the button 19. The button 19 controls the motor 20 to be powered on. The output shaft of the motor 20 rotates to drive the roller 23 to rotate. The rotation of the roller 23 causes the rain shield 24 to rotate and extend. The sliding rod 25 slides downward in the first chute 27 under the action of gravity and pulls the rain shield 24. After the motor 20 rotates a set number of turns, it stops. The sliding rod 25 reaches the lowest point, and the rain shield 24 prevents rainwater from entering the interior of the wind power transformer main body 1 through the gap between the doors.

[0042] During the process of rainwater flowing into the first water storage square pipe 4, when the height of the rainwater does not exceed the bending point of the elbow pipe 29, the rainwater in the first water storage square pipe 4 will not flow out. When the height of the rainwater exceeds the bending point of the elbow pipe 29, due to the siphon effect, the rainwater flows into one end of the elbow pipe 29 and flows out from the elbow pipe 29 until the liquid level is lower than the end of the elbow pipe 29 far from the ground.

[0043] When the heavy rain stops, the rainwater in the first water storage square pipe 4 flows out from the elbow pipe 29, and the water surfaces in the first water storage square pipe 4 and the second water storage square pipe 6 drop. Similarly, the piston 7 drives the sliding rod 8 to move downward. The sliding rod 8 drives the linkage block 31 to move downward. The linkage block 31 drives the connecting rod 11 to move downward. The connecting rod 11 drives the first rack 12 to move downward. During the downward movement of the first rack 12, it drives the gear 13 to rotate through meshing. The rotation of the gear 13 drives the rain shield 14 to rotate downward, reopening the ventilation opening. The movement of the first rack 12 drives the linkage rod 15 to move. The movement of the linkage rod 15 drives the second rack 16 to move. The second rack 16 drives the rain shield 14 on the other side to rotate and reopen the ventilation opening on the other side.

[0044] When the sliding rod 8 releases the button 19 during the downward movement, the button 19 controls the power-on of the motor 20. The output shaft of the motor 20 rotates to drive the drum 23 to rotate in the reverse direction. The rotation of the drum 23 causes the rain shield 24 to rotate and retract. The rain shield 24 pulls the sliding rod 25 upward, causing the sliding rod 25 to slide upward in the first chute 27. After the motor 20 rotates a set number of turns, it stops, and the drum 23 retracts the rain shield 24.

[0045] Embodiment 2

[0046] Please refer to Figure 4 and Figure 5 In this embodiment, for further illustration of Embodiment 1, in the figure, the rain shielding assembly includes a chute rod 22 disposed on one side of the first water storage square pipe 4. The top end of the chute rod 22 is fixedly connected with a fixed block 21. The inner wall of the fixed block 21 is fixedly connected with a motor 20. The outer wall of the output shaft of the motor 20 is fixedly connected with a drum 23. The outer wall of the drum 23 is sleeved with a rain shield 24. The surface of the lower end of the rain shield 24 is fixedly connected with a sliding rod 25. Both ends of the sliding rod 25 are fixedly connected with a limiting rod 26.

[0047] In this embodiment: Through the provided rain shielding assembly, when in extreme weather with heavy precipitation such as a rainstorm, and rainwater flows into the second water storage square pipe 6 and pushes the piston 7 and the sliding rod 8 upward, the sliding rod 8 presses the button 19, and the button 19 controls the power-on of the motor 20. The output shaft of the motor 20 rotates to drive the drum 23 to rotate. The rotation of the drum 23 causes the rain shield 24 to rotate and extend. The sliding rod 25 slides downward in the first chute 27 by gravity and pulls the rain shield 24. After the motor 20 rotates a set number of turns, it stops, and the sliding rod 25 reaches the lowest point, avoiding rainwater from invading the interior of the transformer through the gaps between the doors. Impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in the insulation resistance, and further reducing the insulation performance of the transformer, which may pose a potential safety hazard problem for subsequent workers to open the door for equipment maintenance or repair. It improves the waterproof performance of the wind power transformer and ensures the insulation performance of the equipment and the safety of the workers.

[0048] Please refer to Figure 5 and Figure 8 In the figure, the inner wall of the bottom end of the first water storage square pipe 4 is fixedly connected with an elbow pipe 29. One end of the elbow pipe 29 passes through the base 32 and extends to the bottom end of the base 32. The distance from the other end of the elbow pipe 29 to the top end of the base 32 is less than the distance from the top end of the communication port 5 to the top end of the base 32.

[0049] In this embodiment: Through the bent pipe 29 provided, when the wind power transformer is in extreme weather with heavy precipitation such as rainstorms, when rainwater flows into the first water-receiving square pipe 4, the height of the rainwater does not exceed the bending point of the bent pipe 29, and the rainwater in the first water-receiving square pipe 4 will not flow out. When the height of the rainwater exceeds the bending point of the bent pipe 29, due to the siphon effect, the rainwater flows in from one end of the bent pipe 29 and flows out from the bent pipe 29 until the liquid level is lower than the end of the bent pipe 29 farther from the ground. This avoids the problem that the rainwater in the first water-receiving square pipe 4 flows in and out while not pushing the sliding rod 8, that is, the sliding rod 8 does not drive the gear 13 and the rainshield 14 to rotate to block the ventilation opening, which slows down the startup of the closing component and thus affects the waterproof ability of the device, improving the reliability of the device. First, it flows in to start the closing component and then flows out, accelerating the startup of the closing component and improving the waterproof performance of the wind power transformer.

[0050] Please refer to Figure 2 , in the figure, the cross-section of the water chute 18 is set as an inclined plane; when the wind power transformer is in extreme weather with heavy precipitation such as rainstorms and the closing component blocks the ventilation opening, the rainwater slides down from the top cover 2 of the transformer box body and falls into the two water-receiving troughs 3 on both sides, and then flows into the water chute 18 from the two water-receiving troughs 3 through the water inlet trough 17 respectively. The rainwater entering from the water-receiving trough 3 on the side far from the rainshield 24 flows through the inclined setting of the water chute 18 and moves to the side close to the rainshield 24 to form the confluence of rainwater and flows into the first water-receiving square pipe 4, using the flow of rainwater in the water chute 18 for heat dissipation and reducing the increase in internal temperature due to the blockage of the ventilation opening.

[0051] Please refer to Figure 3 and Figure 6 , in the figure, a water outlet 30 is opened on the side of the first water-receiving square pipe 4 far from the main body 1 of the wind power transformer. The water outlet 30 is opened at the top part of the first water-receiving square pipe 4, and the maximum length from one end of the water outlet 30 to the top of the first water-receiving square pipe 4 is greater than the minimum length from the surface of the bent pipe 29 to the top of the first water-receiving square pipe 4.

[0052] In this embodiment: Through the bent pipe 29 provided, when the wind power transformer is in extreme weather with heavy precipitation such as rainstorms and the height of the rainwater exceeds the bending point of the bent pipe 29, due to the siphon effect, the rainwater flows in from one end of the bent pipe 29. When the outflow is less than the inflow, the rainwater will flow out from the water outlet 30, avoiding the problem that the rainwater accumulates in the water chute 18, the top cover 2 of the transformer box body receives more gravity, and the wear of the top cover 2 of the transformer box body is aggravated, improving the drainage efficiency and extending the service life of the equipment.

[0053] Embodiment 3

[0054] Please refer to Figure 4 and Figure 7, in the illustration, a first chute 27 is provided on the surface of the chute rod 22, a second chute 28 is provided on one side of the first chute 27, the sliding rod 25 is slidably connected to the outer wall of the first chute 27, and the limiting rod 26 is slidably connected to the outer wall of the second chute 28.

[0055] In this embodiment: through the provided first chute 27, when in extreme weather such as heavy rain for the wind power transformer, when rainwater flows into the second water receiving square pipe 6 and pushes the piston 7 and the sliding rod 8 to move upward, the output shaft of the motor 20 rotates to drive the roller 23 to rotate. The rotation of the roller 23 causes the rainproof film 24 to rotate and extend. The sliding rod 25 slides downward in the first chute 27 by gravity and pulls the rainproof film 24. When the sliding rod 25 slides to the lowest point, it prevents the wind from blowing the rainproof film 24 and causing the rainproof film 24 to flutter, which affects the rainproof ability of the rainproof film 24, improves the waterproof performance of the wind power transformer, and effectively covers and protects the transformer from rain.

[0056] Please refer to Figure 5 and Figure 8 , in the illustration, the diameter of the inner groove of the first water receiving square pipe 4 is larger than the diameter of the water receiving groove 10; when in extreme weather such as heavy rain for the wind power transformer, when the rainwater in the first water receiving square pipe 4 flows into the water receiving groove 10 in the second water receiving square pipe 6 through the communication port 5, the first water receiving square pipe 4 and the second water receiving square pipe 6 form a communicating vessel through the communication port 5, so that the rainwater in the water receiving groove 10 gives a greater thrust to the piston 7, improving the reliability of the device.

[0057] Please refer to Figure 6 and Figure 9 , in the illustration, the cross-section of the rainshield 14 is set in a "Z" shape, the lengths of the two sides of the rainshield 14 extending out are equal, and the maximum length between the upper and lower ends of the rainshield 14 is equal to twice the minimum length between the upper and lower ends of the rainshield 14.

[0058] In this embodiment: through the provided rainshield 14, when in extreme weather such as heavy rain for the wind power transformer, when the gear 13 rotates to drive the rainshield 14 to rotate upward, since one end of the lower rainshield 14 can be completely engaged with one end of the upper rainshield 14 during the rotation process, a tight sealing structure is formed, effectively blocking the intrusion of rainwater and improving the waterproof performance of the wind power transformer.

[0059] Please refer to Figure 3 and Figure 6 , in the illustration, a button 19 is provided above the sliding rod 8, the button 19 is provided on the surface of the top cover 2 of the transformer box body, the input end of the button 19 is connected to the output end of the internal power supply of the wind power transformer main body 1; the output end of the button 19 is connected to the input end of the motor 20, and the model of the motor 20 is YS7124.

[0060] In this embodiment: By means of the provided button 19, when the wind power transformer is in extreme weather with heavy precipitation such as rainstorms, and the piston 7 pushes the sliding rod 8 to move upward, the sliding rod 8 presses the button 19 during the upward movement. The button 19 controls the motor 20 to be powered on to lower the rainproof film 24. While blocking the ventilation opening, the rainproof film 24 is lowered to prevent rainwater from invading the transformer interior through the gaps between the doors. This dual protection greatly improves the waterproof performance of the transformer in extreme weather.
