It is mainly used for the distribution, control and protection of electric energy. It has specific structural and performance requirements to adapt to the complex and harsh working environment in the mine.

[0003] When the existing mine power supply system uses a high-voltage distribution cabinet in a mine environment, coal ash and other dust in the mine easily fall into the distribution cabinet, and the dust will cover the surface of the electrical components, resulting in serious dust accumulation inside the distribution cabinet. This not only affects the heat dissipation performance of the electrical components, but may also cause electrical failures, while increasing the difficulty and cost of equipment maintenance.

[0004] There are a lot of dangerous gases in the mine, such as methane, which may enter the inside of the distribution cabinet. When the electrical components in the distribution cabinet produce sparks, it is possible to detonate the dangerous gases, causing serious accidents such as explosions. In addition, when repairing and replacing components such as lamps in the existing distribution cabinet, workers need to enter the distribution cabinet to operate, which increases the risk of electric shock and mechanical injuries.

The staff can repair the lamp 104 without reaching into the power distribution cabinet body 1, which is convenient and quick.

[0083] The present invention also drives the first screw rod 505 and the first rotating wheel 513 to rotate as a whole through the output end of the dual-axis motor 504. Under the drive of the belt 515, the second screw rod 508 and the second rotating wheel 514 rotate as a whole, driving the first movable seat 507 and the second movable seat 510 to move synchronously, so that the connecting rods 511 on the front and rear sides rotate synchronously, which can realize driving the first buffer plate 502 and the second buffer plate 503 to rotate; by providing the first buffer plate 502 and the second buffer plate 503, the upper end of the distribution cabinet has better buffering performance, thereby increasing the firmness of the distribution cabinet. When sand, gravel, ore blocks and other falling objects fall from the top of the distribution cabinet and hit the top of the distribution cabinet, the anti-collision structure can reduce the impact force to avoid the distribution cabinet from being dented. If sand, gravel and ore blocks are accumulated on the first buffer plate 502 and the second buffer plate 503, they can also be kept tilted, so that the sand, gravel and ore blocks slide down;

[0084] Electrical components are usually installed inside the distribution cabinet body 1. The present invention adopts a square ring-shaped frame 401, and drives the second screw 402 to rotate through the output end of the driving motor 404, so that the moving block 405 slides back and forth along the outer surface of the second guide rod 403, and the cooling fans 406 inside and outside the moving block 405 can respectively blow off the surface of the electrical components and the inner wall of the distribution cabinet body 1; and the first screw 302 is driven to rotate through the output end of the stepper motor 304, so that the lifting block 305 slides back and forth up and down along the outer surface of the first guide rod 303. The lifting block 305 and the frame 401 are magnetically connected, thereby driving the frame 401 to move up and down, changing the height of the dust removal mechanism 4, and when the dust removal mechanism 4 is damaged, it can be directly removed from the lifting block 305, which is convenient and quick, and the cleaned dust slides through the inclined plate 106 and flows out from the dust outlet 107.
