[0046] Specific implementation steps: The starting motor 2 drives two rotating shafts 21 to rotate via two rotating gears 23. The rotation of the two rotating shafts 21 drives two rotating wheels 22 to rotate, causing the fixed box 11 to move on the track 1. The rotation of the rotating shafts 21 drives the rotating sleeve 15 to rotate via the belt drive assembly 24. The rotation of the rotating sleeve 15 drives the protective cover 16 to rotate, so that the protective cover 16 is in a rotating state. The rotation of the rotating gears 23 drives the cylindrical block 39 to rotate. The rotation of the cylindrical block 39 drives the strip ring 38, the U-shaped slide bar 36 and the rack 35 to reciprocate. The movement of the rack 35 drives the ring gear 310. The swing sleeve 3 and the swing rod 31 swing, which in turn drives the rotating rod 32, the arc-shaped suction pipe 33, and the brush 34 to swing, causing the brush 34 to clean the protective cover 16. The swing of the rotating rod 32 drives the fixed pipe 52 and the slider 51 to swing, which in turn drives the arc-shaped piston 53 to reciprocate inside the arc-shaped cylinder 54. When the arc-shaped piston 53 moves inward, it creates a negative pressure inside the arc-shaped cylinder 54, which draws air through the one-way air inlet pipe 55, the fixed pipe 52, and the arc-shaped suction pipe 33, thereby sucking the cleaned dust into the arc-shaped suction pipe 33. Inside, the air enters the fixed tube 52 through the air inlet 56. Under the action of the dustproof net 57, the dust falls to the bottom of the fixed tube 52. When the arc-shaped piston 53 moves outward, the gas in the arc-shaped cylinder 54 is introduced into another arc-shaped suction pipe 33 through the one-way air outlet pipe 59 and the jet head 510. Then, the air is sprayed out from the arc-shaped suction pipe 33 to blow and clean the brush bristles 34, thereby blowing the dust on the brush bristles 34 out of the mounting box 12 through the strip-shaped through hole. When the fixed tube 52 swings to the top of the dust discharge hole 58, the dust in the fixed tube 52 is discharged through the dust discharge hole 58. The rotating sleeve 15 rotates through the two conical teeth. Wheel 44 drives reciprocating screw 41 to rotate. The rotation of reciprocating screw 41 drives reciprocating bushing 42 to move back and forth. The movement of reciprocating bushing 42 drives fixed bar 45 and rotating block 46 to move. When rotating block 46 moves towards fixed plate 412, rotating block 46 squeezes fixed plate 412 and drives rotating rod 32 to rotate 90°. Rotating rod 32 drives arc-shaped suction pipe 33 to rotate, thereby automatically switching arc-shaped suction pipe 33, improving the cleaning effect on protective cover 16. With the cooperation of fixed post 48, pin 49 and compression spring 410, rotating rod 32 can be fixed.
