For details, please refer to Figure 1 and Figure 5 The rope 132 is used to connect the arm assembly 120 and the cleaning module 133, so that the cleaning module 133 can be suspended on the arm assembly 120, and the range of movement of the cleaning module 133 is controlled by the rope 132. The rope 132 is required to have high strength, high load-bearing capacity and excellent wear resistance to ensure that the cleaning module 133 can be safely suspended and operated. The second driving member 131 is used to drive the extension or retraction of the rope 132. By controlling the extension or retraction degree of the rope 132, the position and movement of the cleaning module 133 are adjusted.

As the second drum 134 rotates, the rope 132 can be gradually wound onto the second drum 134 or gradually unwound from the second drum 134. When the rope 132 is gradually wound onto the second drum 134, the rope 132 can drive the cleaning module 133 to rise upward or restrain the range of movement of the cleaning module 133 on the surface to be cleaned to gradually decrease; when the rope 132 is gradually unwound from the second drum 134, the cleaning module 133 can descend or move within a larger area of ​​the surface to be cleaned.

When the other end of the rope 132 is gradually wound around the second drum 134, the overall unfolded length of the rope 132 gradually shortens, so as to drive the cleaning module 133 to rise upward or restrain the range of movement of the cleaning module 133 on the surface to be cleaned to gradually decrease; when the other end of the rope 132 is gradually unfolded from the second drum 134, the overall unfolded length of the rope 132 gradually lengthens, and the cleaning module 133 can be lowered or move in a larger area of ​​the surface to be cleaned. In addition, by winding the rope 132 around the movable pulley of the cleaning module 133, the friction and tension of the rope 132 can be reduced, and the force required to stretch the rope 132 can be reduced, so as to easily support the movement of the rope 132 and reduce the wear of the rope 132.

The first telescopic arm 123a is configured to be a cantilever with a fixed end connected to the body 110, the first pulley 125a is connected to the fixed end of the first telescopic arm 123a, the second pulley 125b is connected to the free end of the first telescopic arm 123a, the third pulley 125c is connected to the second telescopic arm 123b and is close to the free end, the fourth pulley 125d is connected to the second telescopic arm 123b and is close to the fixed end, one end of the first rope 126a is connected to the second telescopic arm 123b, and the other end passes through the first pulley 125a and the second pulley 125b to connect the second telescopic arm 123b. 23b and is close to the fixed end, one end of the second rope 126b is connected to the second pulley 125b and is suitable for being wound around the second pulley 125b, and the other end passes around the third pulley 125c to be connected to the third telescopic arm 123c and is close to the fixed end of the third telescopic arm, one end of the third rope 126c is connected to the second telescopic arm 123b and is close to the free end, and the other end passes around the fourth pulley 125d to be connected to the third telescopic arm 123c, the winch drive mechanism 124 is connected to the first telescopic arm 123a, and is drivingly connected to the first rope 126a, for driving the boom 121 to extend and retract. When the arm 121 needs to be retracted, the winch driving mechanism 124 starts to rotate in the first direction under the drive of the motor, and a friction force is generated between the first rope 126a and the winch driving mechanism 124, and the first rope 126a is driven to move under the action of the friction force. One end of the first rope 126a passes around the first pulley 125a and the second pulley 125b, and the movement of the first rope 126a drives the first pulley 125a and the second pulley 125b to move. The second pulley 125b includes two symmetrically arranged pulleys, and a connecting shaft is provided between the two pulleys. The movement of the second pulley 125b drives the first rope 126a to wind around the second pulley 125b, thereby generating a pulling force on the other end of the first rope 126a, and the other end of the first rope 126a is connected to the fixed end of the second telescopic arm 123b. Under the action of the pulling force of the first rope 126a, the fixed end of the second telescopic arm 123b retracts toward the fixed end of the first telescopic arm 123a. One end of the second rope 126b is fixed on the connecting shaft of the second pulley 125b. When the second pulley 125b rotates, the second rope 126b can be wound around the connecting shaft of the second pulley 125b. The overall length of the second rope 126b becomes shorter and generates a certain pulling force on the third pulley 125c connected to the free end of the second telescopic arm 123b, thereby driving the free end of the second telescopic arm 123b to shrink toward the fixed end of the first telescopic arm 123a.The second telescopic arm 123b contracts toward the fixed end of the first telescopic arm 123a, and the fourth pulley 125d provided at the fixed end of the second telescopic arm 123b also moves toward the fixed end of the first telescopic arm 123a, generating a certain pulling force on the third rope 126c wound around the fourth pulley 125d, thereby driving the third telescopic arm 123c connected to the other end of the third rope 126c to also move toward the fixed end of the first telescopic arm 123a. The second telescopic arm 123b and the third telescopic arm 123c both move toward the fixed end of the first telescopic arm 123a, and the arm frame 121 gradually completes the contraction. On the contrary, when the boom 121 needs to be extended, the winch drive mechanism 124 starts to rotate in the second direction driven by the motor, and the second direction is opposite to the first direction. The second pulley 125b releases the first rope 126a wound on the symmetrical pulleys at both ends and the second rope 126b wound on the connecting shaft, and the second telescopic arm 123b and the third telescopic arm 123c move toward the fixed end away from the first telescopic arm 123a, and the boom 121 gradually completes the extension.
