[0025] By setting the traction wheel 27 and the second motor 28, the steel rope 15 can be stably driven, so that the cleaning component is driven by the steel rope 15 to move.

[0026] As shown in Figures 1-5 , the cleaning component includes the cleaning roller shell 17, the ball head seat 16 is fixedly connected at both ends of the cleaning roller shell 17, the steel rope 15 passes through the end of the ball head seat 16, the fastening screw 29 for fixing the steel rope 15 is threadedly connected at the end of the ball head seat 16, the guide sleeve 13 is open on one side and allows the ball head seat 16 to pass through, the guide sleeve 13 is expanded at both ends in a trumpet shape, a group of guide wheels 14 are rotatably connected at the inner side of the bending of the guide sleeve 13, and the guide wheels 14 can be in rolling contact with the steel rope 15 and the ball head seat 16.
