The roller brush 11 is attached to the surface of the electrical components in the power distribution cabinet. A connecting plate 18 is connected between two adjacent brackets 10 located in the middle layer.

[0041] In this embodiment, roller brushes 11 are respectively arranged above and at the bottom of the electrical components. The roller brushes 11 are rotatably connected in the brackets 10. The brackets 10 are slidably connected to the cabinet body 1 through two groups of linear guide rails 9, and can peel off the dust attached to the surface of the electrical components. When driving the roller brushes 11, an elastic cord 17 is arranged on one side of the bracket 10. A traction cord 16 is connected to one end of the elastic cord 17. Pulling the traction cord 16 and the elastic cord 17 can drive the bracket 10 and the roller brushes 11 to move on the linear guide rails 9.

[0042] It should be noted that multiple groups of brackets 5 are arranged in the cabinet body 1, that is, multiple groups of electrical components are arranged horizontally. Except for the two groups of electrical components at the uppermost and lowermost positions, the brackets 10 on the upper and lower sides of the middle electrical components are all connected through the connecting plate 18, so that when the elastic cord 17 pulls the bracket 10, the two roller brushes 11 can move synchronously with the bracket 10, minimizing the use of mechanical structures and preventing the above structures from interfering with other facilities in the cabinet body 1.

[0043] A winding wheel 21 is arranged at the top of the cabinet body 1. A motor 22 is drivingly connected to the top of the winding wheel 21. A traction part is arranged between the winding wheel 21 and the roller brush 11. The traction part includes an elastic cord 17.
