Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer. Background Technology

[0002] A transformer is a type of explosion-proof mobile substation used in mines. It is a device used for power transformation in mines. Transformers include explosion-proof dry-type transformers, explosion-proof high-voltage load switch boxes, and explosion-proof low-voltage feeder switch boxes. Explosion-proof dry-type transformers are a type of transformer that does not require liquid insulation media. Instead, they use dry insulation materials to isolate the windings and the casing. Therefore, the transformer is easier to install and maintain, and it is also more environmentally friendly.

[0003] To facilitate heat dissipation, heat dissipation fins are typically installed on both sides of the transformer casing. These fins are arranged at equal intervals on both sides of the casing. However, since transformers operate in mining environments where dust is easily generated, dust easily accumulates on the heat dissipation fins during use. If the dust on the surface of the heat dissipation fins is not cleaned in time, it will affect the heat dissipation effect of the fins, thus hindering the heat dissipation of the transformer. Summary of the Invention

[0014] As an optional embodiment of the transformer described in this invention, an air storage groove is provided below the second hydraulic oil groove, and an air vent is provided between the air storage groove and the second hydraulic oil groove. A third piston plate is slidably arranged inside the air storage groove, and a fourth spring is fixed between one side of the third piston plate and the inner wall of the air storage groove.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this transformer, during dust removal from the heat dissipation convex plate, a servo motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel, in turn, drives a reciprocating screw to rotate, causing a moving seat to move on the reciprocating screw. The moving seat then moves a cleaning cylinder, which in turn moves a first brush along the surface of the heat dissipation convex plate. This allows the first brush to clean and remove dust from the surface of the heat dissipation convex plate, thus reducing the impact of dust on its heat dissipation effect. Simultaneously, as the moving seat moves the cleaning cylinder, the meshing of gears and gear plates causes the gears to drive a rotating shaft to rotate. This rotation causes the first brush to rotate, increasing the cleaning effect and further improving the dust removal capability as it moves up and down along the surface of the heat dissipation convex plate.

[0017] 2. In this transformer, when the cleaning cylinder moves downward, it first moves from the top receiving slot into the heat dissipation groove. During this process, the cleaning cylinder drives the core rod to move, and the core rod drives the sliding protrusion to slide inside the guide groove, thereby driving the core rod to move. The movement of the core rod drives the slider to slide inside the sliding groove, allowing the second brush to extend from inside the cleaning cylinder and fit against the top surface of the heat dissipation protrusion. At the same time, in conjunction with the rotation of the cleaning cylinder, the second brush can clean the top surface of the heat dissipation protrusion, thereby improving the thoroughness of dust removal from the heat dissipation protrusion and further enhancing the dust removal effect.

[0018] 3. In this transformer, when the sliding protrusion moves downward along the guide groove, it contacts the horizontal plate when it reaches the horizontal plate. This causes the horizontal plate to move downward, which in turn causes the push rod and the first piston plate to move downward. This allows the hydraulic oil in the first hydraulic oil tank to be pumped into the second hydraulic oil tank through the oil delivery groove, thereby pushing the second piston plate to move. The movement of the second piston plate compresses the gas into the gas storage tank. When the first trapezoidal block contacts the second trapezoidal block, the sealing plate moves, opening the air blowing port and blowing the gas in the gas storage tank out through the air blowing port. This facilitates the removal of dust that has fallen into the bottom collection tank. At the same time, the kinetic energy generated by the fourth spring pushing the third piston plate to reset and the instantaneous release of the compressed gas helps to increase the force of the gas blowing out of the air blowing port, thereby further improving the dust removal effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1-9 A transformer includes a transformer body 1. Several sets of heat dissipation protrusions 2 are provided on both outer surfaces of the transformer body 1. A heat dissipation groove 3 is provided between two adjacent sets of heat dissipation protrusions 2. A cleaning cylinder 4 is slidably arranged in the heat dissipation groove 3. A first brush 5 for removing dust from the surface of the heat dissipation protrusions 2 is provided on the outer surface of the cleaning cylinder 4. A servo motor 6 is fixed on the outer surface of the transformer body 1. A worm gear 7 is fixed at the output end of the servo motor 6. A reciprocating screw 8 is rotatably arranged inside the heat dissipation groove 3. A worm wheel 9 is fixed at the top of the reciprocating screw 8. The worm wheel 9 meshes with the worm gear 7. Both the worm gear 7 and the worm wheel 9 are rotatably arranged inside the transformer body 1. A movable seat 10 is threadedly connected to the circumference of the reciprocating screw 8. The movable seat 10 is slidably arranged in the heat dissipation groove 3. A rotating shaft 11 is rotatably arranged on the movable seat 10. One end of the cleaning cylinder 4 is fixedly connected to the rotating shaft 11. The top and bottom of the heat dissipation plate 2 are provided with storage slots 12 for accommodating the cleaning cylinder 4; A toothed plate 13 is fixed on the inner wall of the heat dissipation groove 3, and a gear 14 is fixed on the circumference of the rotating shaft 11. The gear 14 meshes with the toothed plate 13.

[0031] In this technical solution, several sets of cleaning cylinders 4 are set between two adjacent sets of heat dissipation protrusions 2, and the several sets of cleaning cylinders 4 move synchronously. When it is necessary to remove dust from the heat dissipation protrusions 2 on both sides of the transformer body 1, the servo motor 6 first drives the worm gear 7 to rotate, the worm gear 7 drives the worm wheel 9 to rotate, the worm wheel 9 drives the reciprocating screw 8 to rotate, and the reciprocating screw 8 drives the moving seat 10 to slide inside the heat dissipation groove 3. The two sides of the moving seat 10 are engaged in the heat dissipation groove 3, which can limit the moving seat 10, so that when the reciprocating screw 8 rotates, it can only drive the moving seat 10 to move up and down, and will not cause the moving seat 10 to deflect. When the moving seat 10 slides down along the heat dissipation groove 3, the moving seat 10 drives the rotating shaft 11 to move down, the rotating shaft 11 drives the cleaning cylinder 4 to move down, and the cleaning cylinder 4 drives the first brush 5 to move down, so that the first brush 5 can perform dust removal treatment on both sides of the heat dissipation protrusion 2. Simultaneously, through the gear 14 and toothed plate 13, when the rotating shaft 11 moves downward, it drives the gear 14 to move downward. Through the meshing action of the gear 14 and toothed plate 13, the gear 14 rotates. The rotation of the gear 14 drives the rotating shaft 11 to rotate, which in turn drives the cleaning cylinder 4 to rotate. The rotation of the cleaning cylinder 4 drives the first brush 5 to rotate, so that the first brush 5 can rotate on its own when moving up and down, thereby improving the dust removal effect on both sides of the heat dissipation convex plate 2. Moreover, the first brush 5 is closely distributed on the circumference of the cleaning cylinder 4, which can reduce the cleaning dead corners on both sides of the heat dissipation convex plate 2 and increase the thoroughness of dust removal.

[0032] In Example 2, when cleaning the heat dissipation protrusion 2, the first brush 5 can only clean the two sides of the heat dissipation protrusion 2, leaving the top surface uncleaned. This reduces the dust removal effect of the heat dissipation protrusion 2 and affects its heat dissipation performance. To address this issue, this example is an improvement based on Example 1. For details, please refer to Example 2. Figures 1-9 The cleaning cylinder 4 has a sliding groove 15 inside, and a slider 16 is slidably arranged inside the sliding groove 15. One end of the slider 16 is rotatably connected to a core rod 17. A slide rail 18 is provided on the inner wall of the heat dissipation groove 3. The core rod 17 passes through the rotating shaft 11 and the moving seat 10, and the end of the core rod 17 is slidably arranged in the slide rail 18. A second brush 19 is slidably arranged inside the cleaning cylinder 4. The second brush 19 extends out from inside the cleaning cylinder 4 by sliding inside the sliding groove 15 via the slider 16. The transformer body 1 has a guide groove 20 that communicates with the slide rail 18 inside. The end of the core rod 17 is fixed with a sliding protrusion 21. The sliding protrusion 21 is slidably disposed in the guide groove 20. The guide groove 20 includes an inclined part 201 and a vertical part 202 that are connected to each other. The cleaning cylinder 4 has an internal movable groove 22, and a base plate 23 is slidably disposed inside the movable groove 22. The end of the second brush 19 is fixedly disposed on the base plate 23. A connecting rod 24 is fixedly disposed on the surface of the base plate 23. A limiting ball 25 is fixedly disposed at the end of the connecting rod 24. A limiting groove 26 is provided inside the slider 16 for the limiting ball 25 to slide.

[0033] In this technical solution, when the cleaning cylinder 4 moves from the top storage groove 12 to the bottom storage groove 12, the cleaning cylinder 4 first drives the core rod 17 to move downward. The core rod 17 slides inside the slide rail 18, and at the same time drives the sliding protrusion 21 to slide inside the guide groove 20. Figure 6 As shown, when the sliding protrusion 21 slides downward along the inclined portion 201, the sliding protrusion 21 drives the core rod 17 to move to the right. The movement of the core rod 17 to the right drives the slider 16 to move to the right within the sliding groove 15, as shown. Figure 4 As shown, taking the second brush 19 above as an example, when the slider 16 moves to the right, due to the contact between the limiting ball 25 and the limiting groove 26, the limiting ball 25 moves upward along the limiting groove 26. The slider 16 is provided with a moving groove 48 for the connecting rod 24 to slide. The limiting groove 26 is opened on the inner wall of the moving groove 48. The upward movement of the limiting ball 25 drives the connecting rod 24 to move upward, and at the same time, the connecting rod 24 slides inside the moving groove 48. The connecting rod 24 drives the base plate 23 to move upward, and the base plate 23 drives the second brush 19 to move upward, pushing the second brush 19 out of the cleaning cylinder 4. At this time, the pushed-out second brush 19 contacts the top surface of the heat dissipation convex plate 2. Then, the sliding convex post 21 slides along the vertical part 202, causing the cleaning cylinder 4 to move downward. At this time, the cleaning cylinder 4 moves downward and rotates, thereby driving the second brush 19 to rotate, so that the second brush 19 removes dust from the top surface of the heat dissipation convex plate 2, further increasing the thoroughness of dust removal. In this technical solution, when the cleaning cylinder 4 slides from the top storage groove 12 into the heat dissipation groove 3, the sliding protrusion 21 slides from the inclined part 201 to the vertical part 202, so that when the cleaning cylinder 4 slides into the heat dissipation groove 3, the second brush 19 extends completely from the inside of the cleaning cylinder 4, so that when the first brush 5 cleans the two sides of the heat dissipation protrusion 2, the second brush 19 cleans the top surface of the heat dissipation protrusion 2. like Figure 9As shown, the second brush 19 in this application is provided in eight groups, which are evenly distributed on the circumference of the cleaning cylinder 4. Each group of second brushes 19 is arranged in a cluster. When the cleaning cylinder 4 is located in the storage groove 12 at the top, the second brushes 19 are stored inside the cleaning cylinder 4. This can reduce the space occupied by the exposed second brushes 19 and protect the second brushes 19 from damage caused by long-term exposure. In addition, the length of the second brushes 19 extending out of the cleaning cylinder 4 is half of the top surface of the heat dissipation convex plate 2. The two groups of second brushes 19 work together to complete the overall cleaning of the top surface of the heat dissipation convex plate 2.

[0034] In Example 3, when the first brush 5 cleans the dust from both sides of the heat dissipation convex plate 2, a small amount of dust falls into the bottom collection groove 12. This dust is inconvenient to clean with the brush, leading to dust accumulation and affecting the dust removal effect. To address this issue, this example is an improvement based on Example 2. For details, please refer to [link / reference]. Figures 1-9 The transformer body 1 has a first hydraulic oil tank 27 and a second hydraulic oil tank 28 inside. A first piston plate 29 is slidably arranged inside the first hydraulic oil tank 27. A push rod 30 is fixed on the upper surface of the first piston plate 29. The end of the push rod 30 is elastically arranged at the bottom of the guide groove 20. An oil delivery groove 31 is arranged between the first hydraulic oil tank 27 and the second hydraulic oil tank 28. A second piston plate 32 is elastically arranged inside the second hydraulic oil tank 28. An air blowing port 33 is arranged between one side of the second hydraulic oil tank 28 and the bottom receiving groove 12. A spring groove 34 is provided on one side of the guide groove 20. A horizontal plate 35 is fixed to the end of the push rod 30. One end of the horizontal plate 35 is slidably disposed in the spring groove 34. A first spring 36 is fixed between the top of the spring groove 34 and the horizontal plate 35. A second spring 37 is fixed between the surface of the second piston plate 32 and the inner wall of the second hydraulic oil groove 28. A sealing plate 38 is slidably disposed on the air outlet 33. A cavity 39 is opened inside the transformer body 1 for the sealing plate 38 to slide. A force plate 40 is fixed on the top of the sealing plate 38. The force plate 40 is slidably disposed in the cavity 39. A third spring 41 is fixed between the top of the cavity 39 and the force plate 40. A first trapezoidal block 42 is fixed on the outer surface of the sealing plate 38. A second trapezoidal block 43 for abutting against the first trapezoidal block 42 is fixed on the surface of the second piston plate 32. An air storage groove 44 is provided below the second hydraulic oil groove 28. An air vent 45 is provided between the air storage groove 44 and the second hydraulic oil groove 28. A third piston plate 46 is slidably arranged inside the air storage groove 44. A fourth spring 47 is fixed between one side of the third piston plate 46 and the inner wall of the air storage groove 44.

[0035] In this technical solution, when the cleaning cylinder 4 moves downward, causing the core rod 17 to move downward, the core rod 17 drives the sliding protrusion 21 to slide downward along the vertical part 202. When the sliding protrusion 21 is about to slide to the bottom end of the vertical part 202, as... Figure 7 As shown, the sliding protrusion 21 continues to slide downwards. At this time, the sliding protrusion 21 touches the horizontal plate 35 downwards, causing the horizontal plate 35 to drive the push rod 30 to move downwards. The downward movement of the horizontal plate 35 stretches the first spring 36, causing the first spring 36 to store force. The downward movement of the push rod 30 drives the first piston plate 29 to move downwards. The first piston plate 29 fills the hydraulic oil inside the first hydraulic oil tank 27 into the second hydraulic oil tank 28 through the oil delivery tank 31. After the second hydraulic oil tank 28 is filled with hydraulic oil, it pushes the second piston plate 32 to move to the right, causing the second piston plate 32 to fill the air on the right side into the air storage tank 44 through the vent 45. At this time, the second spring 37 and the third spring 41 are compressed and stored force. When the sliding protrusion 21 continues to slide downwards to the bottom of the vertical part 202, the first brush 5 and the second brush 19 complete the overall dust removal of the heat dissipation protrusion 2. The hydraulic oil continues to fill into the second hydraulic oil tank 28, and the second piston plate 32 continues to move to the right, and the gas is compressed to Inside the air storage tank 44, the second piston plate 32 drives the second trapezoidal block 43 to contact the first trapezoidal block 42, causing the first trapezoidal block 42 to move upward. The upward movement of the first trapezoidal block 42 drives the sealing plate 38 to move upward. The upward movement of the sealing plate 38 drives the force plate 40 to move upward inside the cavity 39. The upward movement of the force plate 40 compresses the fourth spring 47, causing the fourth spring 47 to store force. The sealing plate 38 moves upward, causing the sealing plate 38 to open the air outlet 33. At this time, the third spring 41 releases force, pushing the third piston plate 46 to reset, so that the third piston plate 46 instantly discharges the gas inside the air storage tank 44 through the air vent 45 from the air outlet 33. The instantaneously blown gas blows away the dust inside the bottom collection tank 12. Compared with directly blowing the gas out of the air outlet 33 through the second piston plate 32, the force of the gas blowing out is increased, which is conducive to increasing the dust blowing effect and making it easier to blow away the dust on the bottom collection tank 12. In this technical solution, an air inlet communicating with the outside is provided on one side of the air storage tank 44. A one-way valve (not shown in the figure) is installed in the air inlet, so that air can only enter the air storage tank 44 from the outside and cannot exit from the air inlet to the outside. Therefore, when blowing air, the one-way valve is closed, and the compressed gas in the air storage tank 44 will not be blown out through the air inlet, but will be blown out through the air vent 45 and the air blowing port 33. When the second piston plate 32 moves to the left to reset, the sliding protrusion 21 moves upward along the vertical part 202 first, the horizontal plate 35 loses the resistance of the sliding protrusion 21, the first spring 36 is released, and the push rod 30 moves upward. The upward movement of the push rod 30 drives the first piston plate 29 to move upward, drawing the hydraulic oil in the second hydraulic oil tank 28 back to the first hydraulic oil tank 27 through the oil delivery tank 31. The second spring 37 is released. The force causes the second piston plate 32 to move to the left and reset. When the second piston plate 32 resets, it drives the second trapezoidal block 43 to move to the left. The first trapezoidal block 42 loses the resistance of the second trapezoidal block 43, and the third spring 41 releases the force, causing the force plate 40 to move downward in the cavity 39. The force plate 40 drives the sealing plate 38 to move downward, so that the sealing plate 38 blocks the air outlet 33. During this process, the second piston plate 32 moves to the left and resets. Before the air outlet 33 is completely blocked, gas can enter the right space of the second piston plate 32 from the air outlet 33. When the air outlet 33 is completely blocked, the second piston plate 32 continues to move to the left and reset. At this time, the one-way valve opens, and the gas enters the gas storage tank 44 through the air inlet and then enters the right space of the second piston plate 32 through the air outlet 45 until the second piston plate 32 completes the reset.
