A monitoring module for monitoring the dirt on the surface of the photovoltaic panel body 11 is arranged on the inner side of the U-shaped slide 24. The monitoring module includes two monitoring cameras 212 and two side frames 213. The two side frames 213 are respectively fixed on both sides of the inner wall of the U-shaped slide 24, and the two monitoring cameras 212 are respectively fixed between the two sides of the two side frames 213. The control module 26 is used to receive the signal from the monitoring camera 212 to start and close the dual-axis motor 27, the electric push rod 25 and the pulley motor. Through the setting of the above-mentioned structure, the recessed frame 21 limits the position of the multiple floats 1, thereby avoiding the problem that the multiple floats 1 are caused by external forces to drive the corresponding photovoltaic panel bodies 11 to move, resulting in the inconvenience of the traditional cleaning device to clean the photovoltaic panel body 11. At the same time, the monitoring module controls the cleaning cotton board 210 to position and clean the dirt on the surface of the photovoltaic panel body 11, thereby improving the cleaning efficiency of the cleaning device 2 on the photovoltaic panel body 11.

[0018] The scraper 32 is provided with a scraping device 3 on both sides of the swing plate 29, and the scraper 32 includes a Z-shaped frame 31 and a scraper 32. One end of the Z-shaped frame 31 is fixed to the outer wall of the swing plate 29, and the scraper 32 is fixed to the end of the Z-shaped frame 31 away from the swing plate 29, and the bottom of the scraper 32 is in a horizontal state with the cleaning cotton plate 210. The scraper 32 is arranged in a triangular shape on the side away from the swing plate 29, and a semi-arc groove is provided on the top of the scraper 32. Through the arrangement of the above structure, the scraper 32 can effectively remove dust, bird droppings, scale and other dirt attached to the surface of the photovoltaic panel body 11, thereby helping to keep the photovoltaic panel body 11 clean. At the same time, the dirt scraped by the scraper 32 will fall into the semi-arc groove of the scraper 32, thereby avoiding the dirt scraped by the scraper 32 from passing over the scraper 32 and contacting the cleaning cotton plate 210, causing the cleaning cotton plate 210 to be contaminated, which is not conducive to the cleaning cotton plate 210 to clean the photovoltaic panel body 11.

[0019] The scraping device 3 also includes a rotating rod 33, a spiral blade 34, and a rubber wheel 35. The rubber wheel 35 is rotatably installed on one side of the scraper 32. The rotating rod 33 is fixed on the side of the rubber wheel 35 close to the center of the scraper 32. The spiral blade 34 is fixed on the outer wall of the rotating rod 33, and the spiral blade 34 is located inside the semi-arc groove of the scraper 32. Through the arrangement of the above structure, the rotating rod 33 drives the spiral blade 34 to rotate, and the spiral blade 34 pushes the dirt that falls into the semi-arc groove of the scraper 32 downward, thereby avoiding the problem of dirt remaining in the semi-arc groove of the scraper 32 and affecting the use of the scraper 32.

[0020] The scraping device 3 also includes an elastic telescopic rod 36, a plurality of knocking columns 37, a connecting rod 38, an L-shaped abutting rod 39, and an arc block wheel 310. The arc block wheel 310 is fixed to the outer wall of one side of the rotating rod 33, and a semi-arc block is fixed to the outer wall of the arc block wheel 310. The elastic telescopic rod 36 is fixed to the top of the scraper 32 near the swing plate 29. The connecting rod 38 is fixed to the top of the telescopic end of the elastic telescopic rod 36. A plurality of knocking columns 37 are evenly and equidistantly fixed to the bottom of the connecting rod 38, and the bottoms of the plurality of knocking columns 37 are in contact with the top of the scraper 32. The L-shaped resistance rod 39 is fixed on one side of the connecting rod 38, and the bottom of the L-shaped resistance rod 39 is set in a semicircular shape. The semicircular shape of the L-shaped resistance rod 39 is located on the semi-arc block movement trajectory of the arc block wheel 310. Through the setting of the above structure, the knocking column 37 rotates the scraper 32, and the scraper 32 vibrates, which is conducive to the downward discharge of dirt in the semi-arc groove of the scraper 32. At the same time, appropriate vibration can increase the friction between the scraper 32 and the dirt, thereby helping the scraper 32 to more effectively remove stubborn dirt on the photovoltaic panel body 11.

[0021] When in use, the dual-axis motor 27 is started, and the dual-axis motor 27 drives the gear 23 to rotate forward and backward. The toothed plate 22 drives the gear 23 to drive the U-shaped slide 24 to slide back and forth between the two notched frames 21. The U-shaped slide 24 drives the monitoring camera 212 to move along through the side frame 213. When the monitoring camera 212 detects that the surface of the photovoltaic panel body 11 is dirty, the monitoring camera 212 transmits a signal to the control module 26, and the control module 26 stops the dual-axis motor 27 first, and then the control module 26 starts the electric push rod 25, and the telescopic end of the electric push rod 25 pushes The T-shaped push rod 211 moves downward, the T-shaped push rod 211 slides along the inside of the U-shaped rod 28, and the T-shaped push rod 211 pushes the swing plate 29 to swing downward, the swing plate 29 drives the cleaning cotton plate 210 to contact the top surface of the photovoltaic panel body 11, and then the control module 26 starts the pulley motor, the pulley motor drives the screw rod 214 to rotate forward and reversely through the belt, the screw rod 214 drives the threaded block 215 to reciprocate along the outer wall of the U-shaped slide plate 24, and the threaded block 215 drives the swing plate 29 and the cleaning cotton plate 210 to reciprocate, so that the swing plate 29 drives the cleaning cotton plate 210 to move back and forth. The cleaning cotton board 210 cleans the surface of the photovoltaic panel body 11, and the positions of the multiple floats 1 are restricted by the notch frame 21, thereby avoiding the problem that the multiple floats 1 are caused by external forces to drive the corresponding photovoltaic panel body 11 to move, resulting in the inconvenience of the traditional cleaning device to clean the photovoltaic panel body 11. At the same time, the monitoring module controls the cleaning cotton board 210 to position and clean the dirt on the surface of the photovoltaic panel body 11, thereby improving the cleaning efficiency of the cleaning device 2 on the photovoltaic panel body 11. It is worth noting that the U-shaped slide 24 drives the monitoring module 213 to clean the surface of the photovoltaic panel body 11. During the reciprocating movement of the camera 212, the monitoring camera 212 will monitor the dirtiness of the surfaces of the corresponding photovoltaic panel bodies 11 on the multiple floats 1. When there is dirt on the surface of a photovoltaic panel body 11, the monitoring module will control the U-shaped slide plate 24 to drive the swing plate 29 and the cleaning cotton plate 210 to move to the top of the photovoltaic panel body 11. After each cleaning of the photovoltaic panel body 11 is completed, the control module 26 will drive the telescopic end of the electric push rod 25 to drive the T-shaped push rod 211 to move upward, and the T-shaped push rod 211 drives the swing plate 29 to swing upward through the U-shaped rod 28.

[0022] Each time the threaded block 215 drives the swing plate 29 and the cleaning cotton plate 210 to move back and forth, the swing plate 29 drives the scraper 32 to move along through the Z-shaped frame 31, and the scraper 32 shovels the dirt on the surface of the photovoltaic panel body 11. The scraper 32 can effectively remove dirt such as dust, bird droppings, and scale attached to the surface of the photovoltaic panel body 11, thereby helping to keep the photovoltaic panel body 11 clean. At the same time, the dirt scraped by the scraper 32 will fall into the semi-arc groove of the scraper 32, thereby avoiding the dirt scraped by the scraper 32. The dirt will pass over the scraper 32 and contact the cleaning cotton board 210, causing the cleaning cotton board 210 to be contaminated, which is not conducive to the cleaning cotton board 210 to clean the photovoltaic panel body 11; at the same time, the scraper 32 drives the rubber wheel 35 to contact the top surface of the photovoltaic panel body 11, and when the scraper 32 moves, it will drive the rubber wheel 35 to move with it. Under the friction between the rubber wheel 35 and the photovoltaic panel body 11, the photovoltaic panel body 11 will drive the rubber wheel 35 to rotate, and the rubber wheel 35 drives the rotating rod 33 to rotate. 33 drives the spiral blade 34 to rotate, and the spiral blade 34 pushes the dirt that falls into the semi-arc groove of the scraper 32 downward, thereby avoiding the problem that the dirt remains in the semi-arc groove of the scraper 32 and affects the use of the scraper 32; at the same time, the rotating rod 33 drives the arc block wheel 310 to rotate, and the semi-arc block of the arc block wheel 310 pushes the semicircular L-shaped resistance rod 39 to drive the connecting rod 38 to move away from the scraper 32, and the connecting rod 38 drives the telescopic end of the elastic telescopic rod 36 to stretch, and the connecting rod 38 drives the knocking column 37 away from the scraper 32. When the semi-arc block of the arc block wheel 310 no longer pushes the semicircle of the L-shaped resistance rod 39, under the elastic force of the elastic telescopic rod 36, the elastic telescopic rod 36 drives the knocking column 37 to reset through the connecting rod 38, and the knocking column 37 rotates the scraper 32, and the scraper 32 vibrates, which is conducive to the downward discharge of dirt in the semi-arc groove of the scraper 32. At the same time, appropriate vibration can increase the friction between the scraper 32 and the dirt, thereby helping the scraper 32 to more effectively remove stubborn dirt on the photovoltaic panel body 11.

[0023] See also Figure 1 - Fig.11 On the basis of the above embodiment, in another embodiment of the present invention, a spraying device 4 is provided on the top of the swing plate 29.

[0024] The spraying device 4 includes a water storage tank 41, two spraying pipes 42, an L-shaped pressing piece 43, a push rod 44, and a cam rod 45.

On the cam movement trajectory, a spring pump is provided between the L-shaped pressing piece 43 and the two spray pipes 42. The L-shaped pressing piece 43 is used to control the spring pump to extract water from the water tank 41 and transmit it to the two spray pipes 42 for spraying. Through the arrangement of the above structure, the L-shaped pressing piece 43 controls the spring pump to extract water from the water tank 41 and transmit it to the two spray pipes 42 for spraying. The water sprayed from the spray pipes 42 can wet the dirt, making it soft and reducing adhesion, thereby improving the effect of the scraper 32 in removing dirt.

[0025] An L-shaped extrusion plate 46 is fixed to the bottom of the top rod 44, and the L-shaped extrusion plate 46 is located below the cleaning cotton board 210. A groove for accommodating the L-shaped extrusion plate 46 is opened at the bottom of the cleaning cotton board 210. Through the arrangement of the above structure, the L-shaped extrusion plate 46 intermittently squeezes the middle part of the bottom surface of the cleaning cotton board 210. After the middle part of the cleaning cotton board 210 is subjected to force, the two sides of the cleaning cotton board 210 will deform downward, thereby increasing the contact pressure between the two sides of the cleaning cotton board 210 and the surface of the photovoltaic panel, thereby improving the cleaning effect of the cleaning cotton board 210 and helping to remove attached dirt and impurities. At the same time, the L-shaped extrusion plate 46 can intermittently squeeze out the sewage adsorbed by the cleaning cotton board 210.

[0026] When in use, when the rotating rod 33 rotates, the cam rod 45 is driven to rotate, and the cam of the cam rod 45 pushes the push rod 44 to move upward, and the push rod 44 squeezes the pressing end of the L-shaped pressing piece 43. The L-shaped pressing piece 43 controls the spring pump to extract water from the water storage tank 41 and transmits it to the two spray pipes 42 for spraying. The water sprayed from the spray pipes 42 can wet the dirt, make it soft, and reduce adhesion, thereby improving the effect of the scraper 32 in removing dirt; at the same time, when the push rod 44 moves upward, it will drive the L-shaped extrusion plate 46 to move upward, and the L-shaped extrusion plate 46 intermittently squeezes the middle part of the bottom surface of the cleaning cotton plate 210. After the middle part of the cleaning cotton plate 210 is subjected to force, the two sides of the cleaning cotton plate 210 will deform downward, thereby increasing the contact pressure between the two sides of the cleaning cotton plate 210 and the surface of the photovoltaic panel, thereby improving the cleaning effect of the cleaning cotton plate 210 and helping to remove attached dirt and impurities. At the same time, the L-shaped extrusion plate 46 can intermittently squeeze out the sewage adsorbed by the cleaning cotton plate 210.
