Description

Technical Field

[0001] This invention relates to the technical field of transformer platform complete sets of equipment, specifically to a ventilation and heat dissipation device and heat dissipation method for a 10kV pole-mounted transformer platform complete set of equipment. Background Technology

[0002] The 10kV pole-mounted transformer is an outdoor power distribution device used in power systems to convert 10kV high-voltage electricity into low-voltage electricity (such as 400V / 230V). It features compactness, economy, and reliability, and is widely used in rural power grids, urban streets, industrial parks, and other scenarios. The 10kV pole-mounted transformer is a key node in the power distribution network.

[0003] Prior art 1 (Chinese patent CN211879968U, published on 2020-11-06) discloses a complete set of equipment for a 10KV pole-mounted transformer platform, including a column. A slide rail is connected to one outer wall of the column via screws. A first support plate is slidably connected to the inner wall of the bottom end of the slide rail, and a second support plate is slidably connected to the inner wall of the top end of the slide rail. A first rectangular groove is provided at the end of the slide rail near the first support plate, and a first fixing block is connected to the inner wall of the first rectangular groove via screws. A first fixing block is connected to one outer wall of one side via screws. The spring has a first limiting block connected to one side of its outer wall by screws. After maintenance, it slides up via a slide rail. The first support plate presses against the second limiting block, and the second support plate presses against the first limiting block. After rising to a certain height, the first and second limiting blocks reset to support the first and second support plates. The entire maintenance process is simple and quick, reducing the difficulty and labor intensity for maintenance workers. There is also a second existing technology (Chinese patent with announcement number CN222896582U and announcement date of 2025-05-23) for a complete set of equipment for a 10KV pole-mounted transformer platform. The technical solution includes: a column, a base block, a lower worktable, a transformer, a distribution box, an adjustment mechanism, and a positioning mechanism. Two sets of columns are symmetrically arranged, with a lower worktable and an upper worktable movably connected between them. A base block is fixedly connected below the columns, and a positioning mechanism is installed inside each column. A distribution box is installed on the lower worktable, and a transformer is installed on the upper worktable. An adjustment mechanism is provided between the lower and upper worktables. When the telescopic cylinder operates, it drives the connecting piece and the first swing tooth to move. The movement of the first swing tooth causes the second swing tooth on the rotating shaft to rotate as well. Through the swing of the second swing tooth, the second swing tooth cooperates with the grooves on both sides of the lower and upper worktables, ensuring the stability and accuracy of the suspension rope movement, while also guaranteeing the precise positioning and stable support of the worktable.

[0004] While existing technology ensures precise positioning and stable support of the workbench and makes maintenance simple and quick, a large amount of heat accumulates inside the equipment during operation. The equipment has poor heat dissipation efficiency, and when heat accumulates for a long time, it will affect the normal operation of the equipment and may even create certain safety hazards.

[0005] Therefore, we propose a ventilation and heat dissipation device and method for a complete set of 10kV pole-mounted transformer equipment to solve the problems mentioned above. Summary of the Invention

When the heat accumulates for a long time, it will affect the normal operation of the equipment and even create certain safety hazards.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ventilation and heat dissipation device and method for a 10kV pole-mounted transformer platform, comprising a platform mounted on a utility pole, a transformer body fixedly connected to the upper surface of the upper platform, and a distribution box fixedly connected to the upper surface of the lower platform. An outer rotating shaft is rotatably connected to the side of the upper surface of the upper platform, and a swing plate is fixedly connected to the outer side of the outer rotating shaft. A swing mechanism is provided between the outer side of the outer rotating shaft and the interior of the platform. The swing mechanism drives the swing plate to rotate synchronously through the rotation of its gear body to achieve ventilation and heat dissipation for the outside of the transformer body. A gas collection box is penetratingly connected to the lower surface of the platform. A connecting rod is slidably connected to the lower side of the gas collection box, and an adjustment mechanism is provided between the lower end of the connecting rod and the side wall of the distribution box. The adjustment mechanism improves the heat dissipation efficiency of the distribution box by moving the connecting rod.

[0008] Preferably, an air pump is provided through the lower surface of the placement platform, and an air supply hole connected to the transformer body housing is opened on the lower surface of the placement platform, and the interior of the placement platform is hollow.

[0009] Preferably, the swing mechanism includes an inner rotating shaft, which is rotatably connected inside the placement platform, and a fan is fixedly connected to the outside of the inner rotating shaft. The fan drives the inner rotating shaft to rotate under the action of the air force output by the air pump.

[0010] Preferably, a half gear is fixedly connected to the side of the inner rotating shaft, and a gear body that meshes with the half gear is fixedly connected to the outer side of the outer rotating shaft. A torsion spring is fixedly connected to the side of the gear body, and the gear body drives the outer rotating shaft to rotate through the torsion spring. The swing plates are distributed one by one at the four corners of the placement platform.

[0011] Preferably, the adjusting mechanism includes a movable plate, which is slidably connected inside the air collection box, and a first spring is fixedly connected between the lower surface of the movable plate and the air collection box. The upper end of the connecting rod is fixedly connected to the center of the lower surface of the movable plate.

[0012] Preferably, the distribution box has a heat dissipation slot for heat dissipation on the rear side, and a fixing plate is slidably connected inside the heat dissipation slot. The outer side of the fixing plate is fixedly connected to the lower end of the connecting rod. The distribution box also has a ventilation net for auxiliary heat dissipation on the rear side, and the ventilation net is located below the heat dissipation slot.

[0013] Preferably, the inner sides of the fixing plate are fixedly connected with support bars, and a baffle for blocking the ventilation net is fixedly connected between the two sets of support bars. Slider blocks are fixedly connected to the inner sides of both ends of the baffle. The inner wall of the distribution box is provided with a sliding groove, and the slider is slidably connected inside the sliding groove.

[0014] Preferably, a second magnetic block is fixedly connected to the inner side of the ventilation mesh, and a first magnetic block is fixedly connected to the side of the baffle near the ventilation mesh. The positions of the first magnetic block and the second magnetic block correspond one-to-one, and the magnetic poles of the first magnetic block and the second magnetic block are opposite.

[0015] A heat dissipation method for a ventilation and heat dissipation device of a 10kV pole-mounted transformer platform complete set of equipment, characterized by comprising the following steps:

[0016] S1. When the internal temperature sensor of the equipment detects that the temperature is too high, the system controls the start of the air supply pump. The gas enters the inside of the transformer body through the air supply hole of the placement platform to cool and ventilate. At the same time, the heat of the distribution box is discharged from the heat dissipation trough on the rear side to achieve initial heat dissipation.

[0017] S2. When the air pump outputs gas, the airflow blows the fan, which drives the inner rotating shaft and half gear to rotate. The half gear causes the gear body to deflect. When not meshing, the gear body is reset under the action of the torsion spring, realizing reciprocating oscillation. This oscillation drives the outer rotating shaft and oscillating plate to deflect back and forth, providing airflow to the outside of the transformer body. In conjunction with the air pump, it improves heat dissipation efficiency and prevents heat accumulation.

[0018] S3. When the air pump outputs gas, some gas fills the gas collection box, pushing the moving plate along the gas collection box. The moving plate drives the fixed plate to move down via the connecting rod, and the fixed plate then moves the baffle down via the support bar, removing the obstruction to the heat dissipation slots and allowing heat to be better discharged from the distribution box, improving the heat dissipation effect. When the baffle moves, it simultaneously drives the slider to move along the slide groove. The cooperation of the two improves the stability of the baffle movement and achieves more stable position adjustment. When the baffle obstructs the ventilation screen, the first magnetic block on it attracts the second magnetic block on the ventilation screen, and the ventilation screen moves towards the baffle. The movement of the baffle causes the two magnetic blocks to misalign, and the ventilation screen is no longer bound by the magnetic force, bounces outward to reset and shakes off the dust, ensuring normal heat discharge.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) When the internal temperature sensor of the equipment senses that the temperature is too high, the system controls the start of the air supply pump. The gas enters the inside of the transformer body through the air supply hole of the placement platform to cool and ventilate. At the same time, the heat of the distribution box is discharged from the heat dissipation trough on the rear side to achieve preliminary heat dissipation.

[0021] (2) When the gas pump outputs gas, the airflow blows the fan, which drives the inner rotating shaft and half gear to rotate. The half gear causes the gear body to deflect. When not meshing, the gear body is reset under the action of the torsion spring, realizing reciprocating swing. This swing is transmitted through the outer rotating shaft, causing the swing plate to deflect back and forth, fanning the outside of the transformer body. This works in conjunction with the air supply pump to improve heat dissipation efficiency and prevent heat accumulation.

[0022] (3) When the gas pump outputs gas, some gas fills the gas collection box, which pushes the moving plate to move along the gas collection box. The moving plate drives the fixed plate to move down through the connecting rod. The fixed plate then moves the baffle down through the support bar, which removes the obstruction of the heat dissipation slot, allowing the heat in the distribution box to be discharged better and improving the heat dissipation effect.

[0023] (4) When the baffle moves, it will simultaneously drive the slider to slide along a predetermined trajectory inside the groove. With the precise cooperation between the slider and the groove, the stability of the baffle movement process can be effectively enhanced, thereby achieving more stable and precise position adjustment.

[0024] (5) When the baffle blocks the ventilation net, the first magnetic block on the baffle and the second magnetic block on the ventilation net attract each other, causing the ventilation net to adhere to one side of the baffle. When the baffle moves, the first magnetic block and the second magnetic block are misaligned and separated, the ventilation net gets rid of the magnetic restraint, and bounces outward and resets under its own elasticity, while shaking off the dust attached to it, so as to ensure the normal discharge of heat and prevent dust accumulation from hindering heat dissipation.

[0035] 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.

[0036] Example 1: To improve the heat dissipation performance of the equipment, a preliminary heat dissipation function is provided. Through the cooperation of the air supply pump 5 and the heat dissipation tank 7, preliminary heat dissipation can be achieved for the equipment. Figure 1 , Figure 2 and Figure 3 The technical solution shown in the invention provides the following technical solution: a ventilation and heat dissipation device and heat dissipation method for a 10kV pole-mounted transformer platform complete set of equipment, which includes a platform 1 set on a utility pole, a transformer body 3 fixedly connected to the upper surface of the upper platform 1, and a distribution box 2 fixedly connected to the upper surface of the lower platform 1. An air supply pump 5 is provided through the lower surface of the platform 1, and an air supply hole 25 connected to the housing of the transformer body 3 is opened on the lower surface of the platform 1. The platform 1 has a hollow internal structure, and a heat dissipation groove 7 for heat dissipation treatment is opened on the rear side of the distribution box 2.

[0037] When the temperature sensor inside the equipment detects that the temperature is too high, the system controls the start of the air supply pump 5. At this time, the air supply pump 5 outputs gas and inputs the gas into the inside of the transformer body 3 through the air supply hole 25 opened on the upper surface of the placement platform 1. The gas supply cools the transformer body 3, realizes gas exchange, and thus heats it. At the same time, the heat inside the distribution box 2 can be discharged to the outside through the heat dissipation slot 7 opened on its rear side, thus performing preliminary heat dissipation treatment on the equipment.

[0038] Example 2: To improve the heat dissipation efficiency of the equipment, a swing mechanism is provided. This swing mechanism works in conjunction with the air supply pump 5 to achieve coordinated internal and external airflow, further ensuring efficient heat dissipation and preventing heat accumulation. Figure 4 , Figure 5 and Figure 6 The technical solution shown in the invention provides the following solution: a ventilation and heat dissipation device and method for a 10kV pole-mounted transformer platform, which discloses: an outer rotating shaft 14 is rotatably connected to the upper surface of the upper platform 1, and a swing plate 4 is fixedly connected to the outer side of the outer rotating shaft 14. A swing mechanism is provided between the outer side of the outer rotating shaft 14 and the interior of the platform 1. The swing mechanism drives the swing plate 4 to rotate synchronously through the rotation of its included gear body 15 to achieve fan-cooling treatment on the outside of the transformer body 3. The swing mechanism includes an inner rotating shaft 1. 3. The inner rotating shaft 13 is rotatably connected inside the placement platform 1, and a fan 17 is fixedly connected to the outer side of the inner rotating shaft 13. The fan 17 drives the inner rotating shaft 13 to rotate under the action of the air supply pump 5. A half gear 16 is fixedly connected to the side of the inner rotating shaft 13. A gear body 15 that meshes with the half gear 16 is fixedly connected to the outer side of the outer rotating shaft 14, and a torsion spring 18 is fixedly connected to the side of the gear body 15. The gear body 15 drives the outer rotating shaft 14 to rotate through the torsion spring 18. The swing plates 4 are distributed one by one at the four corners of the placement platform 1.

[0039] When the air pump 5 outputs gas, the flowing gas synchronously blows the fan 17, which in turn drives the inner shaft 13 to rotate. During the rotation of the inner shaft 13, the half gear 16 at its edge can be driven to rotate synchronously. At this time, the half gear 16 can drive the gear body 15 meshing with it to deflect. When the half gear 16 is not meshing with the gear body 15, the gear body 15 can be reset under the elastic force of the torsion spring 18, thereby realizing the reciprocating swing of the gear body 15. The reciprocating swing of the gear body 15 can drive the outer shaft 14 to rotate synchronously, thereby driving the swing plate 4 to reciprocate. At this time, the swing plate 4 can fan the outside of the transformer body 3. The output wind force and the output wind force of the air pump 5 work together to further improve the heat dissipation efficiency of the transformer body 3 and prevent heat from accumulating inside the transformer body 3 for a long time.

[0040] Example 3: An adjustment mechanism is provided. This mechanism allows for multiple heat dissipation channels when the equipment overheats, and also seals these channels when not in use to prevent dust from entering. Figure 7 , Figure 8 and Figure 9 The technical solution shown in the invention provides the following solution: a ventilation and heat dissipation device and method for a 10kV pole-mounted transformer platform, which discloses: a gas collecting box 6 is connected through the lower surface of the platform 1, a connecting rod 9 is slidably connected to the lower side of the gas collecting box 6, and an adjustment mechanism is provided between the lower end of the connecting rod 9 and the side wall of the distribution box 2. The adjustment mechanism improves the heat dissipation efficiency of the distribution box 2 by moving the connecting rod 9. The adjustment mechanism includes a moving plate 11, which is slidably connected inside the gas collecting box 6, and a first spring 10 is fixedly connected between the lower surface of the moving plate 11 and the gas collecting box 6. The upper end of the connecting rod 9 is fixedly connected to the center of the lower surface of the moving plate 11. A fixed plate 8 is slidably connected inside the heat dissipation groove 7, and the fixed plate 8... The outer side is fixedly connected to the lower end of the connecting rod 9. The rear side of the distribution box 2 is also provided with a ventilation net 12 for auxiliary heat dissipation, and the ventilation net 12 is located below the heat dissipation groove 7. The inner sides of the fixing plate 8 are fixedly connected with support bars 24, and the two sets of support bars 24 are fixedly connected with a baffle 19 for shielding the ventilation net 12. The inner sides of the two ends of the baffle 19 are fixedly connected with sliders 21. The inner wall of the distribution box 2 is provided with a sliding groove 20, and the slider 21 is slidably connected inside the sliding groove 20. The inner side of the ventilation net 12 is fixedly connected with a second magnetic block 23. The side of the baffle 19 near the ventilation net 12 is fixedly connected with a first magnetic block 22, and the positions of the first magnetic block 22 and the second magnetic block 23 correspond one-to-one, and the magnetic poles of the first magnetic block 22 and the second magnetic block 23 are opposite.

[0041] When the air pump 5 outputs gas, some gas gradually fills the air collection box 6, thus pushing the moving plate 11. The moving plate 11 moves along the inside of the air collection box 6. As the moving plate 11 moves, it simultaneously drives the fixed plate 8 downwards via the connecting rod 9. At this time, the fixed plate 8 simultaneously drives the baffle 19 downwards via the support bar 24. The lowered baffle 19 does not block the heat dissipation slot 7, allowing the heat accumulated inside the distribution box 2 to be better dissipated, improving the equipment's heat dissipation effect. During the movement of the baffle 19, it simultaneously drives the slider 21 to move along the inside of the slide groove 20. The slider 21 and the slide groove... The cooperation of 20 can improve the stability of the movement of the baffle 19, thereby making the position adjustment more stable. When the baffle 19 blocks the ventilation net 12, the first magnetic block 22 on the baffle 19 and the second magnetic block 23 on the ventilation net 12 attract each other. At this time, the ventilation net 12 will move closer to the baffle 19. When the baffle 19 moves, the first magnetic block 22 and the second magnetic block 23 will be misaligned synchronously. The ventilation net 12 is not affected by the elasticity at this time. The ventilation net 12 can bounce back to its original position and shake off the dust attached to it, thereby ensuring that heat can be discharged normally and avoiding the phenomenon that dust attachment affects heat discharge.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
