Description

Technical Field

[0001] The present invention relates to the technical field of intelligent temperature-controlled dry-type transformer equipment, and specifically relates to an intelligent temperature-controlled dry-type transformer and its usage method. Background Art

[0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, CNC machinery equipment, etc. Simply put, a dry-type transformer refers to a transformer in which the iron core and windings are not immersed in insulating oil. A temperature-controlled dry-type transformer can automatically control the turning on of the cooling fan according to the internal temperature of the substation box, use the cooling fan to blow air inside the substation box for heat dissipation, and the cooling fan is assembled inside the air box, and the air box can be conveniently disassembled from the substation box to facilitate the maintenance of the cooling fan.

[0003] Among them, when dissipating heat by blowing air, the fan blades will come into contact with most of the dust in the air. After long-term use, a large amount of dust will accumulate on the outer wall of the fan blades, which will reduce the heat dissipation effect of the transformer and affect the rotation efficiency of the fan blades. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an intelligent temperature-controlled dry-type transformer, including a base, a filter cylinder one fixedly connected to the side wall of the base, a hollow hole plate fixedly connected to the side wall of the filter cylinder one, a fixing rod fixedly connected to the side wall of the hollow hole plate, and a support frame fixedly connected to the other end of the fixing rod;

[0005] A driving mechanism, the driving mechanism includes a motor fixedly connected to the inner wall of the support frame, a sliding cross rod slidably connected to the output shaft of the motor, a first threaded rod slidably connected to the outer wall of the sliding cross rod, and a control component rotatably connected to the outer wall of the first threaded rod;

[0006] Cooling mechanism, the cooling mechanism includes a rotating box fixedly connected to the other end of the first threaded rod. A collecting wheel is rotatably connected to the inner wall of the rotating box. Five fan blades are fixedly connected to the outer wall of the rotating box. A counterweight block is slidably connected to the outer walls of the five fan blades. A pulling wire is fixedly connected to the side wall of the counterweight block. A return spring is fixedly connected to the side wall of the collecting wheel. A driving component is fixedly connected to the side wall of the rotating box. Aiming at the problem that there will be more impurities remaining outside the fan blades after the equipment operates, a driving mechanism and a cooling mechanism are arranged inside the equipment. Before use, the base is installed on the side wall of the transformer, and then the power supply of the motor is turned on. The motor drives the first threaded rod and the rotating box to rotate through the sliding cross rod. The rotating box drives the surrounding fan blades to rotate to cool the inside of the transformer. During this process, as the rotation speed of the fan blades increases, the centrifugal force generated by the fan blades increases, forcing the counterweight block to slide outward along the outer wall of the fan blade to clean the outer wall of the fan blade. And after stopping operation, the return spring releases mechanical power to force the multiple counterweight blocks to reset, and at the same time, the outer wall of the fan blade is cleaned again.

[0007] Preferably, the control component includes a first threaded cylinder threadedly connected to the outer wall of the first threaded rod. A second threaded cylinder is fixedly connected to the outer wall of the first threaded cylinder. A third threaded cylinder is threadedly connected to the outer wall of the second threaded cylinder. The outer wall of the third threaded cylinder is rotatably connected to the outer wall of the support frame. A pulling wire is arranged inside the equipment. When the rotating box rotates, the multiple counterweight blocks will move outward along the corresponding fan blades, and the fan blades drive the same collecting wheel to rotate at an angle through the corresponding pulling wires. By the angular rotation of the return spring, the length of the multiple pulling wires extending outward is controlled indirectly, and the specific position of the counterweight block on the corresponding fan blade is controlled. Through the application of the above components, it is avoided that the fan blades are vertically installed. When the fan blades rotate, the upper and lower counterweight blocks are at different positions on the corresponding fan blades, resulting in the rotation center of gravity of the fan blades and the rotating box shifting, affecting the cooling efficiency of the fan blades.

[0008] Preferably, the control component further includes a hollow rod rotatably connected to the outer wall of the rotating box. A sliding rod is slidably connected to the inner wall of the hollow rod. The other end of the sliding rod is fixedly connected to a fixing frame. A telescopic frame is slidably connected to the outer wall of the fixing frame. Utilizing the characteristic that the first threaded rod drives the rotating box to rotate, a control component is arranged inside the equipment, such as Figure 6 shown. When the first threaded rod rotates clockwise, the first threaded rod will first perform threaded rotation along the inner wall of the first threaded cylinder, and the first threaded rod will gradually move horizontally towards the direction of the motor. After the first threaded rod completely enters the inside of the first threaded cylinder, the clockwise rotation force of the first threaded rod will drive the second threaded cylinder to move horizontally along the inner wall of the third threaded cylinder towards the direction of the rotating box through the first threaded cylinder, forcing the first threaded rod, the first threaded cylinder, and the second threaded cylinder to move horizontally along the inner wall of the third threaded cylinder towards the direction of the rotating box. At the same time, the first threaded rod drives the hollow rod to push the fixing frame to move horizontally through the rotating box, forcing the telescopic frame to deform, presenting as Figure 2The state of the telescopic frame, the fan blades drive air to spray outwards through the gaps of the telescopic frame to achieve the cold air process. Through the application of the above components, the fan blades drive external air to spray outwards through the gaps between the telescopic frames. While increasing the air flow rate, the single air flow is transformed into multiple dispersed air flows, improving the cooling efficiency of the transformer.

[0009] Preferably, the other end of the return spring is fixedly connected to the inner wall of the rotating box, the other end of the pulling wire is fixedly connected to the inner wall of the collecting wheel, and the other end of the return spring is fixedly connected to the inner wall of the rotating box.

[0010] Preferably, the driving component includes a rotating ring rotatably connected to the side wall of the rotating box, a fixed ring rotatably connected to the side wall of the support frame, and three hydraulic telescopic rods I fixedly connected to the side wall of the fixed ring.

[0011] Preferably, the driving component further includes a transmission pipe connected through the side wall of the hydraulic telescopic rod I. A rotating orifice plate is rotatably connected to the inner wall of the hollow orifice plate, and a filter cylinder II is rotatably connected to the inner wall of the filter cylinder I. Taking advantage of the characteristic that the counterweight block cleans the outer wall of the fan blade, when the fan blade rotates in the early stage and forces the counterweight block to slide along the outer wall of the fan blade for cleaning, the counterweight block will scrape off the impurities on the outer wall of the fan blade. During this process, the first threaded rod also moves along the inner wall of the first threaded cylinder towards the motor direction. The first threaded rod drives the rotating box to move synchronously. At the same time, the rotating box moves synchronously along the outer wall of the sliding rod through the hollow rod, so that the telescopic frame is in a closed state, presenting a state as shown in Figure 5 . The closed telescopic frame will hinder air circulation, and the inner arc-shaped wall of the telescopic frame will force the air flow to flow towards the motor along the inner wall of the telescopic frame. Through the application of the above components, it is ensured that the impurities scraped off by the counterweight block from the fan blade for the first time will flow outwards in the direction of the motor along with the air flow, and finally be discharged through the gaps between the holes of the hollow orifice plate and the rotating orifice plate, avoiding the direct entry of impurities into the transformer in the early stage and causing an increase in the internal dust of the transformer.

[0012] Preferably, the driving component further includes a driving plate fixedly connected to the side wall of the second filter cylinder. A fixed square plate is fixedly connected to the side wall of the hollow hole plate. A second hydraulic telescopic rod is fixedly connected to the side wall of the fixed square plate. The other end of the second hydraulic telescopic rod is fixedly connected to the side wall of the driving plate. The other end of the transmission pipe is connected to the outer wall of the second hydraulic telescopic rod in a penetrating manner. By utilizing the characteristic that the distance between the rotating box and the support frame decreases when the above equipment operates, a first hydraulic telescopic rod is arranged inside the equipment. When the rotating box approaches the support frame, the rotating box will squeeze the first hydraulic telescopic rod, forcing the liquid inside the first hydraulic telescopic rod to be transmitted through the transmission pipe into the second hydraulic telescopic rod. At the same time, it forces the second hydraulic telescopic rod to generate movement. The second hydraulic telescopic rod will cause the second filter cylinder and the rotating hole plate to change angles, making the holes of the rotating hole plate misaligned with the holes of the hollow hole plate, so that the above two components form a sealed state. The angular deviation of the second filter cylinder will force the holes of the second filter cylinder to coincide with the holes of the first filter cylinder, forming an air inlet hole, enabling external air to enter the equipment through the above air inlet hole for the cooling process. By changing the air inlet in the above manner, when the equipment operates, the amount of dust entering the equipment can be reduced through the second filter cylinder and the first filter cylinder.

[0013] A method for using an intelligent temperature-controlled dry-type transformer includes the following steps:

[0014] S1: Install the equipment;

[0015] S2: Connect the power supply;

[0016] S3: Start cooling.

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

[0018] (1) In view of the problem that a large amount of impurities will remain outside the fan blades after the device operates, a driving mechanism and a cooling mechanism are provided inside the device. Before use, the base is installed on the side wall of the transformer, and then the motor power is turned on. The motor drives the first threaded rod and the rotating box to rotate through the sliding cross rod. The rotating box drives the surrounding fan blades to rotate to cool the inside of the transformer. During this process, as the rotation speed of the fan blades increases, the centrifugal force generated by the fan blades increases, forcing the counterweight blocks to slide outward along the outer wall of the fan blades to clean the outer wall of the fan blades. After stopping operation, the reset spring releases mechanical power to force the multiple counterweight blocks to reset. At the same time, the outer wall of the fan blades is cleaned again. In addition, a pulling wire is provided inside the device. When the rotating box rotates, the multiple counterweight blocks will move outward along the corresponding fan blades. The fan blades drive the same collecting wheel to rotate at an angle through the corresponding pulling wires. By the angular rotation of the reset spring, the length of the multiple pulling wires extending outward is controlled indirectly, and the specific position of the counterweight blocks on the corresponding fan blades is controlled. Through the application of the above components, it is avoided that the fan blades are vertically installed. When the fan blades rotate, the upper and lower counterweight blocks are at different positions on the corresponding fan blades, resulting in the deviation of the rotation center of the fan blades and the rotating box, affecting the cooling efficiency of the fan blades.

[0019] (2) Utilizing the characteristic that the first threaded rod drives the rotating box to rotate, a control component is provided inside the device. As Figure 6 shown, when the first threaded rod rotates clockwise, the first threaded rod will first rotate along the inner wall of the first threaded cylinder in a threaded manner, and the first threaded rod will gradually move horizontally towards the motor. After the first threaded rod completely enters the first threaded cylinder, the clockwise rotation force of the first threaded rod will drive the second threaded cylinder to move horizontally along the inner wall of the third threaded cylinder towards the rotating box through the first threaded cylinder, forcing the first threaded rod, the first threaded cylinder, and the second threaded cylinder to move horizontally along the inner wall of the third threaded cylinder towards the rotating box. At the same time, the first threaded rod drives the hollow rod through the rotating box to push the fixed frame to move horizontally, forcing the telescopic frame to deform, presenting the state of the telescopic frame as in Figure 2 . The fan blades drive the air to spray outwards through the gaps of the telescopic frame to achieve the cold air process. Through the application of the above components, the fan blades drive the external air to spray outwards through the gaps between the telescopic frames, increasing the air flow rate while converting a single air flow into multiple dispersed air flows, improving the cooling efficiency of the transformer.

[0020] (3) Utilizing the characteristic that the counterweight blocks clean the outer wall of the fan blades, when the fan blades rotate in the early stage and force the counterweight blocks to slide along the outer wall of the fan blades for cleaning, the counterweight blocks will scrape off the impurities on the outer wall of the fan blades. During this process, the first threaded rod also moves towards the motor along the inner wall of the first threaded cylinder. The first threaded rod drives the rotating box to move synchronously. At the same time, the rotating box moves synchronously along the outer wall of the sliding rod through the hollow rod, making the telescopic frame in a closed state, presenting as in Figure 5In the open state of the telescopic frame, air circulation is unobstructed. When the telescopic frame is closed, it will hinder air circulation. The inner arc-shaped wall of the telescopic frame will force the air flow to flow along the inner wall of the telescopic frame towards the motor. Through the application of the above components, it is ensured that the impurities scraped off the fan blades by the counterweight block will flow outwards in the direction of the air flow towards the motor, and finally be discharged through the gap between the holes of the hollow hole plate and the rotating hole plate, avoiding the direct entry of impurities into the transformer in the early stage and causing an increase in internal dust of the transformer.

[0021] (4) Taking advantage of the characteristic that the distance between the rotating box and the support frame decreases during the operation of the above equipment, a first hydraulic telescopic rod is arranged inside the equipment. When the rotating box approaches the support frame, the rotating box will squeeze the first hydraulic telescopic rod, forcing the liquid inside the first hydraulic telescopic rod to be transmitted through the transmission pipe into the second hydraulic telescopic rod. At the same time, it forces the second hydraulic telescopic rod to move, and the second hydraulic telescopic rod will cause the filter cylinder 2 and the rotating hole plate to change their angles, making the holes of the rotating hole plate misaligned with the holes of the hollow hole plate, so that the above two components form a closed state. The angular deviation of the filter cylinder 2 will force the holes of the filter cylinder 2 to coincide with the holes of the filter cylinder 1, forming an air inlet hole, enabling external air to enter the equipment through the above air inlet hole for the cooling process. By changing the air inlet method as described above, when the equipment is operating, the amount of dust entering the equipment can be reduced through the filter cylinder 2 and the filter cylinder 1.

[0037] Cooling mechanism 3, the cooling mechanism 3 includes a rotating box 31 fixedly connected to the other end of the first threaded rod 23. A collecting wheel 32 is rotatably connected to the inner wall of the rotating box 31. Five fan blades 33 are fixedly connected to the outer wall of the rotating box 31. A counterweight 34 is slidably connected to the outer walls of the five fan blades 33. A pulling wire 35 is fixedly connected to the side wall of the counterweight 34. A return spring 36 is fixedly connected to the side wall of the collecting wheel 32. A driving assembly 5 is fixedly connected to the side wall of the rotating box 31. Aiming at the problem that a large amount of impurities will remain outside the fan blades 33 after the equipment runs, a driving mechanism 2 and a cooling mechanism 3 are arranged inside the equipment. Before use, the base 1 is installed on the side wall of the transformer, and then the power supply of the motor 21 is turned on. The motor 21 drives the first threaded rod 23 and the rotating box 31 to rotate through the sliding cross bar 22, and the rotating box 31 drives the surrounding fan blades 33 to rotate to cool the inside of the transformer. In this process, as the rotation speed of the fan blades 33 increases, the centrifugal force generated by the fan blades 33 increases, forcing the counterweight 34 to slide outward along the outer wall of the fan blades 33 to clean the outer wall of the fan blades 33. And after stopping the operation, the return spring 36 releases mechanical power to force the plurality of counterweights 34 to reset. At the same time, the outer wall of the fan blades 33 is cleaned again.

[0038] Embodiment 2, please refer to Figure 5 - Figure 9 , the present invention is an intelligent temperature-controlled dry-type transformer. On the basis of Embodiment 1, the control component 4 includes a first threaded cylinder 41 threadedly connected to the outer wall of the first threaded rod 23. A second threaded cylinder 42 is fixedly connected to the outer wall of the first threaded cylinder 41. A third threaded cylinder 43 is threadedly connected to the outer wall of the second threaded cylinder 42. The outer wall of the third threaded cylinder 43 is rotatably connected to the outer wall of the support frame 14. A pulling wire 35 is arranged inside the equipment. When the rotating box 31 rotates, the plurality of counterweights 34 will move outward along the corresponding fan blades 33, and the fan blades 33 drive the same collecting wheel 32 to rotate at an angle through the corresponding pulling wires 35. By the angular rotation of the return spring 36, the length of the plurality of pulling wires 35 extending outward is controlled, indirectly controlling the specific position of the counterweight 34 on the corresponding fan blade 33. Through the application of the above components, it is avoided that the fan blades 33 are vertically installed. When the fan blades 33 rotate, the upper and lower counterweights 34 are at different positions on the corresponding fan blades 33, resulting in the rotation center of gravity of the fan blades 33 and the rotating box 31 shifting, affecting the cooling efficiency of the fan blades 33.

[0039] The control component 4 further includes a hollow rod 44 rotatably connected to the outer wall of the rotating box 31. A sliding rod 45 is slidably connected to the inner wall of the hollow rod 44. The other end of the sliding rod 45 is fixedly connected to a fixed frame 46. A telescopic frame 47 is slidably connected to the outer wall of the fixed frame 46. Taking advantage of the characteristic that the above-mentioned first threaded rod 23 drives the rotating box 31 to rotate, a control component 4 is arranged inside the equipment, such as Figure 6As shown, when the first threaded rod 23 rotates clockwise, the first threaded rod 23 will first perform threaded rotation along the inner wall of the first threaded cylinder 41, and the first threaded rod 23 will gradually move horizontally towards the direction of the motor 21. After the first threaded rod 23 completely enters the inside of the first threaded cylinder 41, the force of the clockwise rotation of the first threaded rod 23 will drive the second threaded cylinder 42 to move horizontally along the inner wall of the third threaded cylinder 43 towards the rotation box 31 through the first threaded cylinder 41, forcing the first threaded rod 23, the first threaded cylinder 41, and the second threaded cylinder 42 to move horizontally along the inner wall of the third threaded cylinder 43 towards the rotation box 31. At the same time, the first threaded rod 23 drives the hollow rod 44 through the rotation box 31 to push the fixed frame 46 to move horizontally, forcing the telescopic frame 47 to deform, presenting as Figure 2 In the state of the telescopic frame 47 in, the fan blade 33 drives air to spray outwards through the gaps of the telescopic frame 47 to achieve the cold air process. Through the application of the above components, the fan blade 33 drives external air to spray outwards through the gaps between the telescopic frames 47. While increasing the air flow rate, the single air flow is transformed into multiple dispersed air flows, improving the cooling efficiency of the transformer.

[0040] The other end of the return spring 36 is fixedly connected to the inner wall of the rotation box 31, the other end of the pulling wire 35 is fixedly connected to the inner wall of the collecting wheel 32, and the other end of the return spring 36 is fixedly connected to the inner wall of the rotation box 31.

[0041] The driving assembly 5 includes a rotating ring 51 rotatably connected to the side wall of the rotation box 31, a fixed ring 52 rotatably connected to the side wall of the support frame 14, and three first hydraulic telescopic rods 53 fixedly connected to the side wall of the fixed ring 52.

[0042] The driving assembly 5 further includes a transmission pipe 54 penetrating and connected to the side wall of the first hydraulic telescopic rod 53, a rotating orifice plate 55 rotatably connected to the inner wall of the hollow orifice plate 12, and a second filter cylinder 56 rotatably connected to the inner wall of the first filter cylinder 11. Utilizing the characteristic of the counterweight block 34 to clean the outer wall of the fan blade 33, when the fan blade 33 rotates in the early stage and forces the counterweight block 34 to slide along the outer wall of the fan blade 33 for cleaning, the counterweight block 34 will scrape off the impurities on the outer wall of the fan blade 33. During this process, the first threaded rod 23 also moves towards the motor 21 along the inner wall of the first threaded cylinder 41. The first threaded rod 23 drives the rotation box 31 to move synchronously. At the same time, the rotation box 31 moves synchronously along the outer wall of the sliding rod 45 through the hollow rod 44, making the telescopic frame 47 in a closed state, presenting as Figure 5 In the state of, the closed telescopic frame 47 will hinder the air circulation, and the inner arc-shaped wall of the telescopic frame 47 will force the air flow to flow towards the motor 21 along the inner wall of the telescopic frame 47. Through the application of the above components, it is ensured that the impurities scraped off by the counterweight block 34 from the fan blade 33 for the first time will flow outwards towards the motor 21 along with the air flow, and finally be discharged through the gaps between the holes of the hollow orifice plate 12 and the rotating orifice plate 55, avoiding the direct entry of impurities into the transformer in the early stage and causing an increase in the internal dust of the transformer.

[0043] The driving assembly 5 further includes a driving plate 57 fixedly connected to the side wall of the second filter cylinder 56. A fixed square plate 59 is fixedly connected to the side wall of the hollow hole plate 12. A second hydraulic telescopic rod 58 is fixedly connected to the side wall of the fixed square plate 59. The other end of the second hydraulic telescopic rod 58 is fixedly connected to the side wall of the driving plate 57. The other end of the transmission pipe 54 is connected to the outer wall of the second hydraulic telescopic rod 58 in a penetrating manner. Utilizing the characteristic that the distance between the rotating box 31 and the support frame 14 decreases when the above equipment operates, a first hydraulic telescopic rod 53 is arranged inside the equipment. When the rotating box 31 approaches the support frame 14, the rotating box 31 will squeeze the first hydraulic telescopic rod 53, forcing the liquid inside the first hydraulic telescopic rod 53 to be transmitted through the transmission pipe 54 into the inside of the second hydraulic telescopic rod 58. At the same time, forcing the second hydraulic telescopic rod 58 to generate movement along, along which the second hydraulic telescopic rod 58 will cause the second filter cylinder 56 and the rotating hole plate 55 to change their angles, so that the holes of the rotating hole plate 55 are misaligned with the holes of the hollow hole plate 12, making the above two components form a sealed state. And the angular deviation of the second filter cylinder 56 will force the holes of the second filter cylinder 56 to coincide with the holes of the first filter cylinder 11, forming an air inlet hole, enabling external air to enter the equipment through the above air inlet hole for the cooling process. By changing the air inlet method in the above way, when the equipment operates, the amount of dust entering the equipment can be reduced through the second filter cylinder 56 and the first filter cylinder 11.

[0044] The usage method of the intelligent temperature-controlled dry-type transformer includes the following steps:

[0045] S1: Install the equipment;

[0046] S2: Connect the power supply;

[0047] S3: Start cooling down.

[0048] A specific application of this embodiment is as follows: Before use, the base 1 is installed on the side wall of the transformer. Subsequently, the power supply of the motor 21 is turned on. The motor 21 drives the first threaded rod 23 and the rotating box 31 to rotate through the sliding cross rod 22. The rotating box 31 drives the surrounding fan blades 33 to rotate, cooling the inside of the transformer. During this process, as the rotation speed of the fan blades 33 increases, the centrifugal force generated by the fan blades 33 increases, forcing the counterweight blocks 34 to slide outward along the outer wall of the fan blades 33 to clean the outer wall of the fan blades 33. After stopping operation, the return spring 36 releases mechanical power to force the multiple counterweight blocks 34 to reset. At the same time, the outer wall of the fan blades 33 is cleaned again. In addition, a pulling wire 35 is provided inside the device. When the rotating box 31 rotates, the multiple counterweight blocks 34 will move outward along the corresponding fan blades 33. The fan blades 33 drive the same collecting wheel 32 to rotate at an angle through the corresponding pulling wires 35. By the angular rotation of the return spring 36, the length of the multiple pulling wires 35 extending outward is controlled, indirectly controlling the specific position of the counterweight blocks 34 on the corresponding fan blades 33. Through the application of the above components, it is avoided that the fan blades 33 are vertically installed. When the fan blades 33 rotate, the upper and lower counterweight blocks 34 are at different positions on the corresponding fan blades 33, resulting in the deviation of the rotation center of gravity of the fan blades 33 and the rotating box 31, affecting the cooling efficiency of the fan blades 33.

[0049] Taking advantage of the characteristic that the first threaded rod 23 drives the rotating box 31 to rotate, a control component 4 is provided inside the device, as Figure 6 shown. When the first threaded rod 23 rotates clockwise, the first threaded rod 23 will first perform a threaded rotation along the inner wall of the first threaded cylinder 41, and the first threaded rod 23 will gradually move horizontally in the direction of the motor 21. After the first threaded rod 23 completely enters the first threaded cylinder 41, the clockwise rotation force of the first threaded rod 23 will drive the second threaded cylinder 42 to move horizontally along the inner wall of the third threaded cylinder 43 in the direction of the rotating box 31 through the first threaded cylinder 41, forcing the first threaded rod 23, the first threaded cylinder 41, and the second threaded cylinder 42 to move horizontally along the inner wall of the third threaded cylinder 43 in the direction of the rotating box 31. At the same time, the first threaded rod 23 drives the hollow rod 44 through the rotating box 31 to push the fixed frame 46 to move horizontally, forcing the telescopic frame 47 to deform, presenting the state of the telescopic frame 47 as shown in Figure 2 . The fan blades 33 drive the air to spray outwards through the gaps of the telescopic frame 47 to achieve the cold air process. Through the application of the above components, the fan blades 33 drive the external air to spray outwards through the gaps between the telescopic frames 47. While increasing the air flow rate, the single air flow is transformed into multiple dispersed air flows, improving the cooling efficiency of the transformer.

[0050] Taking advantage of the feature that the outer wall of the fan blade 33 is cleaned by the counterweight 34, when the fan blade 33 rotates in the early stage, forcing the counterweight 34 to slide along the outer wall of the fan blade 33 for cleaning, the counterweight 34 will scrape off the impurities on the outer wall of the fan blade 33. During this process, the first threaded rod 23 also moves along the inner wall of the first threaded cylinder 41 towards the motor 21. The first threaded rod 23 drives the rotating box 31 to move synchronously. At the same time, the rotating box 31 moves synchronously along the outer wall of the sliding rod 45 through the hollow rod 44, causing the telescopic frame 47 to be in a closed state, presenting a state as shown in Figure 5 In this state, the closed telescopic frame 47 will hinder air circulation. The inner arc wall of the telescopic frame 47 will force the air flow to flow towards the motor 21 along the inner wall of the telescopic frame 47. Through the application of the above components, it is ensured that the impurities scraped off the fan blade 33 by the counterweight 34 for the first time will flow outwards in the direction of the motor 21 along with the air flow, and finally be discharged outwards through the gap between the holes of the hollow hole plate 12 and the rotating hole plate 55, avoiding the direct entry of impurities in the early stage into the transformer interior and causing an increase in dust inside the transformer. Taking advantage of the feature that the distance between the rotating box 31 and the support frame 14 decreases during the operation of the above equipment, a first hydraulic telescopic rod 53 is provided inside the equipment. When the rotating box 31 approaches the support frame 14, the rotating box 31 will squeeze the first hydraulic telescopic rod 53, forcing the liquid inside the first hydraulic telescopic rod 53 to be transmitted through the transmission pipe 54 into the second hydraulic telescopic rod 58. At the same time, it forces the second hydraulic telescopic rod 58 to generate movement. The second hydraulic telescopic rod 58 will cause the filter cartridge two 56 and the rotating hole plate 55 to change angles, making the holes of the rotating hole plate 55 misaligned with the holes of the hollow hole plate 12, causing the above two components to form a sealed state. The angular deviation of the filter cartridge two 56 will force the holes of the filter cartridge two 56 to coincide with the holes of the filter cartridge one 11, forming an air inlet hole, enabling external air to enter the equipment interior through the above air inlet hole for the cooling process. By changing the air inlet method as described above, when the equipment is operating, the amount of dust entering the equipment can be reduced through the filter cartridge two 56 and the filter cartridge one 11.
