Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0016] like Figure 1-9 As shown, an embodiment of the present invention provides a removable multi-partition high-voltage cabinet, including a cabinet body 1, an instrument installation compartment 2 is provided on the top of the cabinet body 1, and a busbar installation compartment 3, a circuit breaker installation compartment 4 and an incoming and outgoing cable installation compartment 5 are provided in sequence from top to bottom inside the cabinet body 1. The instrument installation compartment 2, the busbar installation compartment 3, the circuit breaker installation compartment 4 and the incoming and outgoing cable installation compartment 5 are all prior art (application number 202410226814.0), and will not be described in detail here. The interior thereof is used to install corresponding electrical equipment (not shown in this application); A guide rail 6 is fixedly connected to the rear wall of the circuit breaker installation compartment 4. A movable groove 7 is provided inside the guide rail 6. A sliding hole 8 is provided on the front side wall of the guide rail 6. A roller 9 is provided inside the movable groove 7. The roller 9 is rotatably connected to the rotating shaft 10 through a bearing. The arrangement of the guide rail 6, movable groove 7, sliding hole 8, roller 9 and rotating shaft 10 facilitates the movement of the frame 11. The front end of the rotating shaft 10 is fixedly connected to the frame 11. A baffle 12 is fixedly connected to the left side wall of the frame 11. A handle 13 is fixedly connected to the left side wall of the baffle 12. A first conduit 14 is fixedly connected to the top of the guide rail 6, and an upper through hole 15 is provided between the first conduit 14 and the guide rail 6. A second conduit 16 is fixedly connected to the bottom of the guide rail 6, and a lower through hole 17 is provided between the second conduit 16 and the guide rail 6. A piston cylinder 18 is fixedly connected to the rear wall of the cabinet 1, and a piston plate 19 is slidably connected to the inner wall of the piston cylinder 18. A pull rod 20 is fixedly connected to the left side wall of the piston plate 19. A piston-type sliding connection is adopted between the pull rod 20 and the piston cylinder 18 to ensure the sealing of the piston cylinder 18. A pull block 21 is fixedly connected to the left end of the pull rod 20, and a connecting rod 22 is fixedly connected between the pull block 21 and the baffle 12. The arrangement of the pull rod 20, the pull block 21, and the connecting rod 22 facilitates the movement of the piston plate 19 with the frame 11. The piston plate 19 divides the interior of the piston cylinder 18 into two independent chambers. When the piston plate 19 moves with the frame 11, the volumes of the two chambers change, thereby realizing simultaneous suction and blowing. A first gas exhaust mechanism 23 and a second gas exhaust mechanism 24 are fixedly connected to the rear wall of the cabinet 1 . The first gas exhaust mechanism 23 is disposed correspondingly to the first conduit 14 , and the second gas exhaust mechanism 24 is disposed correspondingly to the second conduit 16 .

[0017] The first gas extraction mechanism 23 includes a filter box 231, a slot 232, a filter plate 233, a first connecting pipe 234, an outlet check valve 235, a second connecting pipe 236, an inlet check valve 237, a delivery pipe 238, a sealing plate 239, a handle 2310, and a third connecting pipe 2311. The outlet check valve 235 is configured to allow gas inside the filter box 231 to enter the delivery pipe 238 only through the outlet check valve 235, while gas inside the delivery pipe 238 cannot enter the filter box 231 through the outlet check valve 235. The inlet check valve 237 is configured to allow gas inside the delivery pipe 238 to enter the filter box 231 only through the inlet check valve 237, while gas inside the filter box 231 cannot enter the delivery pipe 238 through the inlet check valve 237. This structural design prevents collected dust from being blown out again. After the filter box 231 has been used for a period of time, the filter plate 233 needs to be removed for dust cleaning. The filter box 231 is fixedly connected to the rear wall of the cabinet 1, and the bottom of the filter box 231 is fixedly connected to the third connecting pipe 2311, the bottom end of the third connecting pipe 2311 is connected to the piston cylinder 18, and a slot 232 is provided on the inner wall of the filter box 231, and the inner wall of the slot 232 is slidably connected to the filter plate 233, and a sealing plate 239 is fixedly connected to the rear wall of the filter plate 233, and a handle 2310 is fixedly connected to the rear wall of the sealing plate 239. The top of the filter box 231 is fixedly connected to the second connecting pipe 236, and the second connecting pipe 236 is provided with an air intake check valve 237. The side wall of the filter box 231 is fixedly connected to the first The connecting pipe 234 is provided with an air outlet check valve 235. The first connecting pipe 234 is located below the filter plate 233. The first connecting pipe 234 and the second connecting pipe 236 are fixedly connected to the delivery pipe 238 through a three-way pipe fitting. The top of the delivery pipe 238 is connected to the first conduit 14. A sealing gasket is provided between the filter plate 233 and the slot 232. A sealing ring is provided between the sealing plate 239 and the filter box 231 to prevent air leakage. It should be noted that a locking structure (not shown in the figure) needs to be provided between the sealing plate 239 and the filter box 231 to prevent the sealing plate 239 from opening automatically. The working principles of the first gas pumping mechanism 23 and the second gas pumping mechanism 24 are as follows: When the vehicle frame 11 moves out, the piston plate 19 moves to the left. At this time, the chamber on the left side of the piston plate 19 becomes smaller and starts to blow air. The gas in the filter box 231 (left side) on the second gas extraction mechanism 24 is transported to the delivery pipe 238 through the first connecting pipe 234, and finally transported to the second guide tube 16, blowing up the dust inside the movable groove 7. At the same time, the chamber on the right side of the piston plate 19 becomes larger and starts to inhale air. The delivery pipe 238 on the first gas extraction mechanism 23 transports the gas to the second connecting pipe 236, and the gas enters the filter box 231 (right side). At this time, the filter plate 233 in the filter box 231 filters the dust in the gas. When the frame 11 is pushed in and the piston plate 19 moves to the right, the chamber on the right side of the piston plate 19 becomes smaller and starts to blow air. The gas in the filter box 231 (right side) on the first gas extraction mechanism 23 is transported to the delivery pipe 238 through the first connecting pipe 234 and finally to the first guide tube 14, blowing up the dust inside the movable groove 7. At the same time, the chamber on the left side of the piston plate 19 becomes larger and starts to inhale air. The delivery pipe 238 on the second gas extraction mechanism 24 transports the gas to the second connecting pipe 236, and the gas enters the filter box 231 (left side). At this time, the filter plate 233 in the filter box 231 filters the dust in the gas. The two movement modes of the frame 11 can achieve the simultaneous blowing and absorption of dust in the guide rail 6, thereby preventing the accumulation of dust from affecting the friction of the roller 9 during movement or causing it to become stuck. In addition, this structural design can not only achieve automatic dust cleaning, but also prevent the blown dust from being adsorbed on the electrical equipment inside the high-voltage cabinet. The second gas pumping mechanism 24 has the same structure as the first gas pumping mechanism 23 and is symmetrically arranged on the left and right sides of the piston cylinder 18; A cabinet door 25 is connected to the front side wall of the cabinet body 1 by means of a hinge, and a touch controller 29 is provided on the cabinet door 25. A wire entry hole 26 is provided on the right wall of the incoming and outgoing cable installation compartment 5. A wire trough 27 is provided on the inner wall of the cabinet body 1, and the wire trough 27 passes through the busbar installation compartment 3, the circuit breaker installation compartment 4 and the incoming and outgoing cable installation compartment 5. A connecting hole 28 is provided at the bottom of the instrument installation compartment 2. The design of the wire entry hole 26, the wire trough 27 and the connecting hole 28 facilitates the passage of the wires.
