[0129] In addition, because the sliding platform needs to drive the robot 29 to slide on the sliding assembly, if the control signal and power supply are transmitted by electrical connection, the cables will be complicated and entangled. Therefore, a sliding contact assembly is provided in this embodiment, and the sliding contact assembly is arranged between the slide rail assembly 2 and the cleaning platform, such as Figure 7 and Fig.13 The sliding contact assembly includes a sliding contact line 21 and a current collector 34.

[0130] The busbar 21 is arranged along the slide rail, and the busbar 21 is fixedly connected to the slide rail assembly 2; the collector 34 is slidingly electrically connected to the busbar 21, the collector 34 is fixedly connected to the cleaning platform, and the collector 34 is electrically connected to the motor 27 and the cleaning device 3.

[0131] The control signal of the control box 28 can be transmitted to multiple components, such as the motor 27, the robot 29, the cleaning nozzle 30, the cleaning brush 31, etc., through the sliding contact component.

[0132] The control box 28 controls the motor 27 to provide driving force, and the gear 26 meshes with the rack to drive the cleaning platform to move linearly and accurately position. The dry ice cleaning machine 33 and the liquid storage tank 32 provide liquid carbon dioxide under high pressure, which is sprayed on the parts that need to be cleaned, and cooperates with the cleaning brush 31 at the mobile end of the robot 29 to complete the cleaning of the roof insulator. High-pressure liquid carbon dioxide cleaning replaces the original water cleaning method, avoiding the waste of water resources, and has high cleaning efficiency, low energy consumption, and high raw material utilization.
