[0002] High-voltage cabinets refer to power cabinets used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. They mainly include high-voltage circuit breakers, high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and disconnecting devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. The high-voltage cabinet manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] When existing high-voltage cabinets are dustproof, filters need to be used to cover the ventilation holes. Because the filters will accumulate a lot of dust during long-term use, they need to be disassembled, cleaned or replaced.

[0004] However, when installing the filter screen in the existing device, the bracket for holding the filter screen needs to be fixed in the high-voltage cabinet with bolts. This installation method takes a lot of time and also poses certain safety hazards when workers climb into the cabinet to disassemble and install.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0024] See also Figure 1-Figure 4 The utility model is a high-voltage frequency conversion cabinet with dustproof function, comprising two placement boxes 2 and a box body 1. The two placement boxes 2 are respectively located at the intersection of the inner bottom wall and the inner side wall of the box body 1. Two first springs 3 are fixedly connected to the inner wall of each placement box 2. The other end of each first spring 3 is fixedly connected to a push block 4. When the push block 4 is pushed, the push block 4 will slide horizontally along the corresponding placement box 2 and cause the corresponding first spring 3 to begin to compress. The outer surface of each push block 4 is slidably connected to the corresponding placement box 2. When no external force acts on the push block 4, the first spring 3 will reset the push block 4 under the action of its rebound force. The ends of the two push blocks 4 close to each other are fixedly connected to a rack 6, and all racks 6 are on the same horizontal plane.

[0025] In this embodiment, the ends of the two placement boxes 2 that are close to each other are fixedly connected to a connecting frame 10, which is installed on the corresponding placement box 2 and protects the rack 6. The outer surface of each rack 6 is slidably connected to the corresponding connecting frame 10. The push block 4 pushes the corresponding rack 6 to slide in the connecting frame 10 during the movement. The inner wall of each connecting frame 10 is rotatably connected to a gear 7, and the outer surface of each gear 7 is meshed with the corresponding rack 6. Specifically, the rotation of the gear 7 will drive the corresponding two racks 6 to move horizontally in opposite or reverse directions along the corresponding connecting frame 10, thereby pushing the corresponding push block 4 to slide horizontally.

[0026] In this embodiment, the upper surface of each gear 7 is fixedly connected to a first connecting rod 8, the outer surface of the first connecting rod 8 is rotatably connected to the corresponding connecting frame 10, the top of each first connecting rod 8 is fixedly connected to a first rotating wheel 9, and the bottom surface of each first rotating wheel 9 is rotatably connected to the corresponding connecting frame 10. By rotating the first rotating wheel 9, the first rotating wheel 9 will drive the corresponding first connecting rod 8 to rotate, and drive the corresponding gear 7 to rotate through the first connecting rod 8.

[0027] In this embodiment, the inner wall of the box body 1 is fixedly connected to the two placement boxes 2, and each push block 4 is fixedly connected to an insertion rod 11 at one end away from the corresponding first spring 3. The outer surface of each insertion rod 11 is slidably connected to the corresponding placement box 2. Specifically, the push block 4 will drive the corresponding insertion rod 11 to slide horizontally during the sliding process along the corresponding placement box 2.

[0028] See also Figure 2 Two brackets 12 are provided on the inner wall of the box body 1, and a filter 13 is inserted into the inner wall of each bracket 12. The filter 13 serves as the main dustproof mechanism. The filter 13 is arranged inside the corresponding bracket 12, and the outer surface of each insertion rod 11 is inserted into the corresponding bracket 12. Specifically, when the push block 4 drives the corresponding insertion rod 11 to enter the corresponding placement box 2, the bracket 12 is placed on both sides of the corresponding placement box 2. At this time, the first rotating wheel 9 is released, and the first spring 3 will push the corresponding insertion rod 11 under the action of its rebound force to reset it and insert it into the corresponding bracket 12. At this time, the bracket 12 can rotate around the corresponding insertion rod 11, thereby completing the quick disassembly and assembly of the filter 13.

[0029] In this embodiment, a plurality of ventilation holes 14 are provided on both sides of the box body 1, and a cooling fan 15 is fixedly installed on the inner wall of the box body 1. Specifically, the cooling fan 15 can be started to cool down the electrical components inside the box body 1, and the air flow rate inside the box body 1 can be increased by setting the ventilation holes 14.

[0030] In this embodiment, connecting boxes 18 are fixedly installed on both sides of the box body 1, and the inner walls of the two connecting boxes 18 are slidably connected with second connecting rods 16. The second connecting rods 16 pass through the box body 1 and can slide horizontally along the corresponding connecting boxes 18. The second connecting rods 16 are placed perpendicular to the box body 1, and the outer surface of each second connecting rod 16 is slidably connected to the box body 1. The ends of the two second connecting rods 16 that are close to each other are fixedly connected with a clamping plate 19. Specifically, the second connecting rod 16 is pushed, and the position of the corresponding clamping plate 19 in the box body 1 is changed through the second connecting rod 16, and the bracket 12 is fixed by the clamping connection between the clamping plate 19 and the corresponding bracket 12.

[0031] like Figure 4 As shown, the ends of the two second connecting rods 16 that are away from each other are fixedly connected to the second rotating wheel 17, and the outer surface of each second connecting rod 16 is rotatably connected to the limiting block 5. When the second rotating wheel 17 is rotated, the second rotating wheel 17 will drive the corresponding second connecting rod 16 to rotate, and at this time the limiting block 5 will rotate relatively on the second connecting rod 16.

[0032] In this embodiment, a second spring 20 is sleeved on the outer surface of each second connecting rod 16, one end of each second spring 20 is fixedly connected to the corresponding limit block 5, and the other end is fixedly connected to the box body 1. Specifically, when the second rotating wheel 17 is pushed, the second connecting rod 16 will squeeze the corresponding limit block 5. At this time, the second spring 20 begins to compress until the clamping plate 19 enters the corresponding bracket 12, and then the second rotating wheel 17 is rotated. The second rotating wheel 17 will drive the corresponding clamping plate 19 to fix the bracket 12, and the second rotating wheel 17 is rotated in the opposite direction. The clamping plate 19 is not affected by external force. At this time, the second spring 20 will reset the second connecting rod 16 under the action of its rebound force, thereby unlocking the fixation of the bracket 12.

For those skilled in the art, the present invention may have various modifications and variations.
