[0013] A method for using a transformer oil tank with a protective structure comprises the following steps:

[0014] S1: When using this device, place the transformer and other necessary items inside the oil tank, and then install the oil tank in the designated position. When wind blows from the outside, it will compress the air and pass it into the fixed sleeve 1, so that the sliding joint is pushed to the right and contacts the joint. At this time, a passage is formed between the motor and the power supply and the motor rotates.

[0015] S2: After the motor is started, it will drive the gear rod 1 to rotate, so that the large opening formed between the upper heat conducting plate and the lower heat conducting plate will face the windward direction. When the adjustment plate moves to a certain distance, it will push the pressure rod 2 to move the sliding joint in the opposite direction, so that the sliding joint is separated from the joint, and the motor stops running;

[0016] S3: When the gear threaded rod 1 rotates, it drives the gear threaded rod 2 to rotate, and then drives the scraper to move to the left or right, which can scrape off the oil stains accumulated on the inner wall of the oil tank and discharge the scraped oil stains.

[0017] The present invention has the following beneficial effects:

[0018] (1) After the motor of the present invention is started, it will drive the gear rod 1 to rotate, and the gear rod 1 will drive the gear threaded rod 1 to rotate, thereby driving the adjustment plate to move to the left or right. When the adjustment plate moves to the right, it will push the right side of the upper heat conducting plate upward, push the right side of the lower heat conducting plate downward, and stretch the spring 1 on the right side, thereby making the large openings of the upper heat conducting plate and the lower heat conducting plate face the windward direction, and the other ends of the upper heat conducting plate and the lower heat conducting plate will be close to each other to form a small opening under the action of another spring 1. When the wind blows from the large opening into the air duct formed by the upper heat conducting plate, the lower heat conducting plate and the air shielding plate, it will blow out from the small opening. When the wind blows from the large opening to the small opening, the kinetic energy of the gas increases due to the increase in flow rate and the decrease in static pressure. The temperature drops and more heat can be taken away. When the adjusting plate moves to a certain distance, it will contact the pressure rod 2. As the adjusting plate continues to move, the pressure rod 2 will be pushed into the fixed sleeve 2, and then the air in the fixed sleeve 2 can be pushed into the air guide hose 2. The air guide hose 2 will pass the air into the fixed sleeve 1. The air passed into the fixed sleeve 1 will push the sliding joint in the opposite direction, thereby separating the sliding joint from the joint, and the motor stops running. This design forms a conical air duct by tilting the heat conductive sheet to allow the wind to take away more heat when blowing through the heat conductive sheet, thereby improving the overall heat dissipation effect of the device, reducing the failure rate of the equipment due to excessive temperature, and improving the reliability of the equipment.

[0019] (2) When the wind blows from the left to the right, the front and back windward plates of the present invention will be blown to the right, and the windward plates can freely rotate at a certain angle. This can keep the wind force on the windward plates stable when the wind direction changes within a small range. When the windward plates move to the right, the sliding base will move with them. When the right side of the sliding base contacts the left side of the pressure rod, as the sliding base continues to move to the right, the pressure rod will be pushed to the right and compress the reset spring. At the same time, it will also press the air inside the support column into the air guide tube, and the air guide tube will pass the air into the fixed sleeve. The air passed into the fixed sleeve will Push the sliding joint to the right and finally make contact with the joint. At this time, a passage is formed between the motor and the power supply and the motor rotates. Similarly, when the wind blows from the right to the left, the windward plate will be pushed to the left, thereby connecting the circuit on the left to reverse the motor. The same is true for other windward plates. At the same time, when the windward plate is rotated or moved by the wind, it can also drive away birds to prevent them from entering the bottom of the roof and falling on the high-voltage or low-voltage terminals, affecting the operation of the transformer. This design can control the direction of motor rotation according to the wind direction, so that the heat dissipation component of the device can be changed and adjusted according to the wind direction. At the same time, it can also drive away birds and protect the transformer terminals from being affected.

[0020] (3) A certain amount of insulating oil is generally added to the oil tank of the present invention. After the equipment is used for a long time, a large amount of oil stains will stick to the inner wall of the oil tank, forming an insulating layer or a heat-insulating layer, which hinders the heat dissipation effect of the oil tank to the external environment. The gear threaded rod 1 will drive the gear rod 2 to rotate while rotating. The gear rod 2 will drive the gear threaded rod 2 to rotate when rotating, and then drive the scraper to move to the left or right. The scraper will scrape and clean the oil stains accumulated on the inner wall of the oil tank during the movement. The scraped oil stains will fall onto the sealing plate 1 along the scraper. This design can clean the oil stains through the scraper. Cleaning the oil stains can restore the thermal conductivity of the oil tank surface, improve the heat dissipation efficiency, and thus reduce the operating temperature of the transformer.

[0021] (4) In the present invention, when the scraper drives the sealing plate 1 to move to contact the outer surface of the fixed box, the sealing plate 2 will also contact the scraper, and then a sealed space can be formed at the bottom of the scraper through the sealing plates 1, 2 and the scraper. As the scraper continues to move, it will push the sealing plate 2 and compress the spring 3. At the same time, the sealing plate 1 will not move due to the obstruction of the fixed box. The scraper will compress the spring 2 to continue to move. As the scraper moves, the closed space formed by the sealing plates 2, 1 and the scraper will gradually be compressed and reduced, and the sealing rod will be pushed and compressed by the extrusion force. At this time, the oil scale and a certain amount of insulating oil in the sealed space can enter the fixed box through the through hole exposed after the sealing rod is removed, and finally be discharged from the dirt discharge port of the device. The staff can collect the discharged materials at the bottom of the dirt discharge port for recycling. This design can discharge the scraped oil scale from the oil tank to prevent the accumulation of oil scale in the oil tank, which will affect the circulation and quality of the oil, and may accelerate the aging of the oil or contaminate the impurities in the oil.

[0039] The descaling component 3 includes a gear rod 2 301 rotatably connected to the inner wall of the oil tank 101, the gear rod 2 301 is meshedly connected with a gear threaded rod 2 302 on the side away from the gear threaded rod 1 203, and a scraper 303 is threadedly connected to the outer surface of the gear threaded rod 2 302.

[0040] The inner wall of the roof 103 is slidably connected to a sliding base 105, and the inner wall of the sliding base 105 is rotatably connected to a windward plate 104, and the inner wall of the support column 102 is slidably connected to a pressure rod 106, and the pressure rod 106 is fixedly connected to a return spring 1021 on the side close to the support column 102, and the return spring 1021 is fixedly connected to the inner wall of the support column 102 on the side away from the pressure rod 106. When there is wind blowing from the outside, if the wind blows from the left to the right, the front and back windward plates 104 will be blown to the right, and the windward plates 104 can rotate freely at a certain angle. This can keep the wind force on the windward plate 104 stable when the wind direction changes in a small range, and when the windward plate 104 moves to the right, it will drive the sliding base 105 to move together.

[0041] An air duct 107 is fixedly connected to the outer surface of the support column 102, and an extension shell 210 is fixedly connected to the air duct 107 at the end away from the support column 102. The extension shell 210 is fixedly connected to the outer wall of the oil tank 101 on the side close to the oil tank 101, and a fixed sleeve 108 is fixedly connected to the inner wall of the extension shell 210. When the right side of the sliding base 105 contacts the left side of the pressure rod 106, as the sliding base 105 continues to move to the right, the pressure rod 106 will be pushed to the right and compress the reset spring 1021, and at the same time, it will also press the air inside the support column 102 into the air duct 107, and the air duct 107 will pass the air into the fixed sleeve 108.

Similarly, when the wind blows from the right to the left, the windward plate 104 will be pushed to the left, thereby connecting the circuit on the left and reversing the motor. The same is true for other windward plates 104. At the same time, when the windward plate 104 is rotated or moved by the wind, it can also drive away birds to prevent them from entering the bottom of the roof 103 and falling on the high-voltage or low-voltage terminals, affecting the operation of the transformer.

When the motor 201 is started, it will drive the gear rod 202 to rotate, and the gear rod 202 will drive the gear threaded rod 203 to rotate, thereby driving the adjustment plate 204 to move to the left or right.

After the wind blows from the large mouth to the small mouth, the kinetic energy of the gas increases and the temperature drops due to the increase in flow rate and the decrease in static pressure, which can take away more heat. When the direction adjusting plate 204 moves to a certain distance, it will contact the pressure rod 113. As the direction adjusting plate 204 continues to move, the pressure rod 113 will be pushed into the fixed sleeve 112, and then the air in the fixed sleeve 112 can be pushed into the air guide hose 111.

[0046] The method for using the transformer oil tank with a protective structure includes the following steps:

[0047] S1: When using the device, place the transformer and other necessary items inside the oil tank 101, and then install the oil tank 101 at a designated location. When wind blows from the outside, it will compress the air and pass it into the fixed sleeve 108, so that the sliding joint 109 is pushed to the right and contacts the joint 110. At this time, a passage is formed between the motor 201 and the power source and the motor 201 rotates.

[0048] S2: After the motor 201 is started, it drives the gear rod 1 202 to rotate, so that the large opening formed between the upper heat conducting plate 206 and the lower heat conducting plate 207 faces the windward direction. When the direction adjustment plate 204 moves to a certain distance, it pushes the pressure rod 2 113 to move the sliding joint 109 in the opposite direction, so that the sliding joint 109 is separated from the joint 110, and the motor stops running;

[0049] S3: When the gear threaded rod 1 203 rotates, it drives the gear threaded rod 2 302 to rotate, and then drives the scraper 303 to move to the left or right, which can scrape off the oil stains accumulated on the inner wall of the oil tank 101 and discharge the scraped oil stains.

[0050] A specific application of this embodiment is:

[0051] When using the device, the transformer and other required items are placed inside the oil tank 101, and then the oil tank 101 is installed at a designated position. When there is wind blowing from the outside, if the wind blows from the left to the right, the front and back windward plates 104 will be blown to the right, and at the same time, the windward plates 104 can freely rotate at a certain angle, which can keep the wind force received by the windward plates 104 stable when the wind direction changes in a small range. When the windward plates 104 move to the right, the sliding base 105 will be driven to move together. When the right side of the sliding base 105 contacts the left side of the pressure rod 106, as the sliding base 105 continues to move to the right, the pressure rod 106 will be pushed to the right and compress the reset spring 1021, and at the same time, it will also press the air inside the support column 102 into the air guide pipe 107. The air guide pipe 10 7 will pass air into the fixed sleeve 108, and the air passed into the fixed sleeve 108 will push the sliding joint 109 to the right and finally contact with the joint 110. At this time, a passage is formed between the motor 201 and the power supply and the motor 201 rotates. Similarly, when the wind blows from the right to the left, the above-mentioned windward plate 104 will be pushed to the left, thereby connecting the circuit on the left to reverse the motor. The same is true for other windward plates 104. At the same time, when the windward plate 104 is rotated or moved by the wind, it can also drive away birds to prevent them from entering the bottom of the roof 103 and falling on the high-voltage or low-voltage terminals to affect the operation of the transformer. This design can control the direction of rotation of the motor 201 according to the wind direction, so that the heat dissipation component 2 of the device can be changed and adjusted according to the wind direction. At the same time, it can also drive away birds and protect the transformer terminals from being affected.

[0052] In the above process, after the motor 201 is started, it will drive the gear rod 202 to rotate, and the gear rod 202 will drive the gear threaded rod 203 to rotate, thereby driving the adjustment plate 204 to move to the left or right. When the adjustment plate 204 moves to the right, it will push the right side of the upper heat conducting plate 206 upward, push the right side of the lower heat conducting plate 207 downward, and stretch the spring 209 on the right side, thereby making the large openings of the upper heat conducting plate 206 and the lower heat conducting plate 207 face the windward direction, and the other ends of the upper heat conducting plate 206 and the lower heat conducting plate 207 will be close to each other to form a small opening under the action of another spring 209. When the wind blows from the large opening into the air duct formed by the upper heat conducting plate 206, the lower heat conducting plate 207 and the air shielding plate 208, it will be blown out from the small opening. When the wind blows from the large opening to the small opening, the air will be blown out from the small opening due to the increase in flow rate and the decrease in static pressure. The kinetic energy of the body increases and the temperature decreases, which can take away more heat. When the adjustment plate 204 moves to a certain distance, it will contact the second pressure rod 113. As the adjustment plate 204 continues to move, the second pressure rod 113 will be pushed into the second fixed sleeve 112, and then the air in the second fixed sleeve 112 can be pushed into the second air guide hose 111. The second air guide hose 111 will pass the air into the first fixed sleeve 108. The air passed into the first fixed sleeve 108 will push the sliding joint 109 in the opposite direction, so that the sliding joint 109 is separated from the joint 110, and the motor stops running. This design forms a conical air duct by tilting the heat conducting sheet, so that the wind can take away more heat when blowing through the heat conducting sheet, thereby improving the overall heat dissipation effect of the device, reducing the failure rate of the equipment caused by excessive temperature, and improving the reliability of the equipment;

[0053] A certain amount of insulating oil is generally added to the oil tank 101. After the equipment is used for a long time, a large amount of oil stains will stick to the inner wall of the oil tank 101, forming an insulating layer or a heat-insulating layer, which hinders the heat dissipation effect of the oil tank 101 to the external environment. In the above process, the gear threaded rod 1 203 will drive the gear rod 2 301 to rotate while rotating. The gear rod 2 301 will drive the gear threaded rod 2 302 to rotate when rotating, and then drive the scraper 303 to move to the left or right. The scraper 303 will scrape and clean the oil stains accumulated on the inner wall of the oil tank 101 during the movement. The scraped oil stains will fall on the sealing plate 1 304 along the scraper 303. This design can clean the oil stains through the scraper 303. Cleaning the oil stains can restore the thermal conductivity of the oil tank surface, improve the heat dissipation efficiency, and thus reduce the operating temperature of the transformer.

[0054] In the above process, when the scraper 303 drives the sealing plate 1 304 to move to contact the outer surface of the fixed box 306, the sealing plate 2 307 will also contact the scraper 303, and then a sealed space can be formed at the bottom of the scraper 303 through the sealing plate 1 304, the sealing plate 2 307 and the scraper 303. As the scraper 303 continues to move, it will push the sealing plate 2 307 and compress the spring 308. At the same time, the sealing plate 1 304 will not move due to the obstruction of the fixed box 306, and the scraper 303 will compress the spring 2 305 to continue to move. As the scraper 303 moves, the sealing plates 2 307, the sealing plates 1 307 and the spring 308 are pushed. The enclosed space formed by 04 and the scraper 303 will be gradually compressed and reduced, and the sealing rod 309 will be pushed and compressed by the extrusion force of the spring four 310. At this time, the grease and a certain amount of insulating oil in the sealed space can enter the fixed box 306 through the through hole exposed after the sealing rod 309 is removed, and finally be discharged from the device from the dirt discharge port 311. The staff can collect the discharged materials at the bottom of the dirt discharge port 311 for recycling. This design can discharge the scraped grease from the oil tank 101 to prevent the accumulation of grease in the oil tank 101, which will affect the circulation and quality of the oil, and may accelerate the aging of the oil or contaminate the impurities in the oil.
