[0051] The first protection box 10 and the second protection box 11 provide a mounting space for the moving mechanism 15, and the moving mechanism 15 is used to drive the cleaning scraper 14 to scrape on the top surface of the photovoltaic panel 3 to remove the dirt adhered to the surface.

[0052] As Figure 7 and Figure 9 As a specific technical solution, the moving mechanism 15 includes two first pulleys 1501 and a first transmission belt 1502; the first transmission belt 1502 is arranged around the two first pulleys 1501; the first pulleys 1501 are rotatably installed in the first protection box 10 and the second protection box 11; a connecting shaft 13 is rotatably installed between the first protection box 10 and the second protection box 11; the two ends of the connecting shaft 13 are fixedly connected with the first pulleys 1501 in the first protection box 10 and the first pulleys 1501 in the second protection box 11 respectively; the first transmission belt 1502 is connected with a sliding block 16; the first protection box 10 and the second protection box 11 are both provided with a sliding groove 12; the sliding block 16 is slidably connected with the sliding groove 12; and the sliding block 16 is connected with the end of the cleaning scraper 14.

[0053] As Figure 9 As a specific technical solution, a transmission mechanism 20 is arranged in the second protection box 11; the transmission mechanism 20 includes a second pulley 2002 and a third pulley 2003; the diameter of the third pulley 2003 is greater than that of the second pulley 2002; a second transmission belt 2001 is arranged around the second pulley 2002 and the third pulley 2003; and the second pulley 2002 is coaxially fixedly connected with a first pulley 1501 in the second protection box 11.

[0054] When the third belt wheel 2003 is driven to rotate about the second protection box 11, the second belt wheel 2002 is rotated through the belt drive provided by the second transmission belt 2001, the first belt wheel 1501 is rotated by the second belt wheel 2002, the first transmission belt 1502 is driven to move, the cleaning scraper 14 is driven to move on the photovoltaic panel 3 by the first transmission belt 1502 through the sliding block 16, and the cleaning is realized.

[0055] As shown in Figure 5 and Figure 11 , as a specific technical solution, the number of the support ropes 4 is two; the second adjusting mechanism 8 is installed to one of the support ropes 4, and a plurality of front seats 9 are fixedly installed on the other support rope 4 at equal intervals, the front seat 9 is rotationally installed with a rotating cylinder 17, the rotating cylinder 17 is fixedly connected with the second protection box 11; the circular shaft 18 extending into the rotating cylinder 17 is fixedly connected with the third belt wheel 2003, and the circular shaft 18 is rotationally connected with the second protection box 11, the circular shaft 18 is coaxially arranged with the rotating cylinder 17, and a 180° circular arc groove 1801 is formed on the end surface of the circular shaft 18; the fixed column 19 is fixedly connected with the front seat 9, and the fixed column 19 is inserted into the circular arc groove 1801; the clockwork spring is installed between the circular shaft 18 and the second protection box 11.

[0056] When the photovoltaic panel 3 is in a horizontal state, as shown in Figure 8 , the fixed column 19 is located at the middle of the circular arc groove 1801, after the photovoltaic panel 3 is driven to rotate clockwise to 90°, the fixed column 19 is relatively moved to one end of the circular arc groove 1801, the photovoltaic panel 3 is continuously driven to rotate clockwise, the circular shaft 18 cannot rotate with the photovoltaic panel 3 due to the block of the fixed column 19, the first protection box 10, the second protection box 11 and the structures inside them rotate with the photovoltaic panel 3, so that the circular shaft 18 relatively rotates about the structures and twists the clockwork spring, the first belt wheel 1501 is rotated through the transmission of the third belt wheel 2003, the second belt wheel 2002 and the second transmission belt 2001, the first transmission belt 1502 is driven to move, the cleaning scraper 14 is driven to move by the first transmission belt 1502 through the sliding block 16, and the cleaning of the photovoltaic panel 3 is realized.

The connecting strip 1602 is made of metal iron and can be magnetically attracted.

[0064] In the horizontal state of the photovoltaic panel 3, as shown in the figure, Figure 10 As shown in the figure, Figure 12As shown, at this time, the connecting strip 1602 is attracted by the magnetic block 23, keeps the stretching state of the spring 1603, and the cleaning scraper 14 is attached to the surface of the photovoltaic panel 3; when the photovoltaic panel 3 is cleaned, the sliding block 16 slides in the sliding groove 12, the connecting strip 1602 moves below the blocking strip 22, is blocked by the blocking strip 22, and cannot be moved upward by the elastic force of the spring 1603 until the cleaning is completed; the connecting strip 1602 moves to the end of the back-shaped sliding groove away from the magnetic block 23, loses the blocking of the blocking strip 22, and is moved to the side above the blocking strip 22 by the elastic force of the spring 1603, and the connecting strip 1602 drives the cleaning scraper 14 to separate from the photovoltaic panel 3; when the photovoltaic panel 3 is reset to the horizontal state, the cleaning scraper 14 is reset and moved, and in this process, the cleaning scraper 14 does not rub against the surface of the photovoltaic panel 3, reduces unnecessary abrasion, and the connecting strip 1602 moves above the blocking strip 22; after the resetting is completed, the connecting strip 1602 moves above the magnetic block 23, and is restored to the position of the spring 1603 by the magnetic attraction of the magnetic block 23.
