The switching drive unit 380 starts to work and drives the two rotating connecting parts 360 to move horizontally relative to the adjusting box body 310. The moving rotating connecting part 360 acts on the corresponding bottom of the telescopic cleaning component 400 and makes the telescopic cleaning component 400 rotate around the connection between it and the support toward the side away from the insulator body 200. The telescopic cleaning component 400 gradually rotates to a horizontal state, so when passing through the cable, it will not interfere with the cable. At the same time, the switching drive unit 380 also winds up the retractable traction rope 330, and the retractable traction rope 330 pulls the top of the telescopic cleaning component 400, so that The telescopic cleaning component 400 is retracted; when the telescopic cleaning component 400 is rotated to a horizontal state, it is prevented from colliding with other equipment due to its increased lateral length; but after each telescopic cleaning component 400 passes through the cable, the switching drive part 380 drives the two rotating connecting parts 360 to move back and makes the retractable pulling rope 330 in a relaxed state, and the rotating connecting part 360 drives the corresponding bottom of the telescopic cleaning component 400 and makes the telescopic cleaning component 400 rotate to a vertical state. Since the retractable pulling rope 330 is relaxed, the telescopic cleaning component 400 automatically extends to facilitate cleaning of the subsequent outer wall of the insulator body 200.
