Second limiting slideways 40 are symmetrically provided on both sides of the top of the support device 5.

[0028] The photovoltaic panel 1 is clamped to the center of the two end surfaces of the top of the supporting device 5 through the clamping grooves 8 at both ends, and the fastening screws 7 pass through the limiting cross frame 6 and are threadedly connected to the threaded holes 39, so that the photovoltaic panel 1 can be positioned on the top surface of the supporting device 5. The cleaning device 2 is slidably clamped with the first limiting slides 9 on both sides of the upper surface of the photovoltaic panel 1 through the L-shaped connecting blocks 15 at the bottom of both ends, thereby limiting the sliding of the two ends of the cleaning device 2 on the upper surface of the photovoltaic panel 1. The cleaning device 2 is in rolling contact with the upper surface of the photovoltaic panel 1 through the cleaning roller 12 on the bottom, so that the upper surface of the photovoltaic panel 1 can be rolled and cleaned, and the delivery cross pipe 10 is fixedly connected to the micro pump 35 through the delivery pipes 14 at both ends, so as to convey the clean water.

[0029] The two ends of the transmission shaft 31 are rotationally connected to the center of one side of the driving device 3 through the limiting sleeve 16, so as to play a supporting and limiting role on the two ends of the transmission shaft 31. The two ends of the transmission rod 24 are respectively rotationally connected to the limiting tripod 23 and the top of one side of the support frame 19, so as to play a supporting and limiting role on the two ends of the transmission rod 24.

[0030] The transmission shaft 31 is rotatably meshed with the first planetary gear 21 through the second planetary gear 30 at one end, and can synchronously drive the transmission shaft 31 to rotate when the drive motor 18 is running. The cleaning device 2 is fixedly connected to the upper surfaces of the first chain 27 and the second chain 33 through the L-shaped connecting blocks 15 at both ends, so that when the first chain 27 and the second chain 33 rotate, the cleaning device 2 can be synchronously driven to slide laterally. The winding directions of the connecting ropes 28 on the outer surfaces of the winding shafts 25 at both ends of the two sets of transmission rods 24 are opposite, thereby ensuring that the cleaning scraper 29 is synchronously driven to slide laterally.

[0031] The two ends of the cleaning scraper 29 are slidably engaged with the inner surface of the supporting device 5 on both sides through the second limiting slide 40, which can limit the two ends of the cleaning scraper 29. The connecting rope 28 is slidably overlapped on the outer surface of the limiting cross bar 34, which can ensure that the connecting rope 28 is horizontal inside the supporting device 5 to pull the cleaning scraper 29. The connecting ropes 28 on the outer surfaces of the transmission rods 24 at both ends of the transmission device 4 are respectively fixedly connected to the outer surfaces of the edges at both ends of the cleaning scraper 29, thereby pulling the cleaning scraper 29. The bottom surface of the cleaning scraper 29 is in close sliding contact with the upper surface of the inner center of the top of the supporting device 5, and the two sides of the cleaning scraper 29 are wedge-shaped, which can remove dust on the upper surface of the filter screen 38.

[0032] Working principle: After the photovoltaic panel 1 is used for a long time, a lot of dust will accumulate on the surface of the photovoltaic panel 1, which will affect the normal power generation of the photovoltaic panel 1. Therefore, it is necessary to clean the dust on the upper surface of the photovoltaic panel 1. When cleaning the upper surface of the photovoltaic panel 1, first start the drive motor 18 to drive the fan blades 22 on the top to rotate, so that the fan blades 22 dissipate heat to the bottom surface of the photovoltaic panel 1. At the same time, the fan blades 22 will drive the first planetary gear 21 at the bottom to rotate synchronously. When the first planetary gear 21 rotates, it will drive the second planetary gear 30 on the outer surface to rotate synchronously, and the second planetary gear 30 will drive the first sprocket 32 ​​to rotate synchronously through the transmission shaft 31. When the first sprocket 32 ​​rotates synchronously, it will drive the second chain 33 on the outer surface. The second chain 33 will rotate, and the transmission gears 26 on the inner surfaces of both ends will rotate synchronously. When the transmission gears 26 rotate, the transmission rods 24 on both ends of the transmission device 4 will rotate synchronously, and the transmission rods 24 will drive the first chain 27 to rotate synchronously through the transmission gears 26 at the other end. Therefore, when the first chain 27 and the second chain 33 rotate synchronously, the L-shaped connecting blocks 15 connecting the outer surfaces of the first chain 27 and the second chain 33 will slide synchronously, and the L-shaped connecting blocks 15 will drive the cleaning device 2 to slide horizontally on the upper surface of the photovoltaic panel 1. At the same time, the micro pump 35 needs to be started to extract the clean water inside the water collection tank 36, and transport it to the inside of the delivery cross pipe 10 through the delivery pipe 14, and enter the delivery cross pipe 10. The cleaning water inside will be sprayed on the upper surface of the photovoltaic panel 1 through the second cleaning nozzle 13, and the cleaning device 2 will drive the cleaning roller 12 on the bottom to clean the upper surface of the photovoltaic panel 1. As the cleaning device 2 moves on the upper surface of the photovoltaic panel 1, the dust on the upper surface of the photovoltaic panel 1 will be cleaned to one end edge of the photovoltaic panel 1. When the first chain 27 and the second chain 33 are connected to the L-shaped connecting block 15 and move to one end edge of the photovoltaic panel 1, the driving motor 18 will automatically rotate in the opposite direction, thereby driving the first chain 27 and the second chain 33 to synchronously reverse, and the first chain 27 and the second chain 33 will drive the cleaning device 2 through the L-shaped connecting block 15 to slide back and forth on the upper surface of the photovoltaic panel 1, thereby cleaning the upper surface of the photovoltaic panel 1 back and forth. The cleaning process is continued until the upper surface of the photovoltaic panel 1 is cleaned, wherein the cleaning water sprayed by the second cleaning nozzle 13 will drive the removed dust to flow to the outer edge of the photovoltaic panel 1, and finally drip into the interior of the supporting device 5 below, and fill the interior of the overflow groove 37, and the excess cleaning water will overflow the overflow groove 37 and pass through the filter screen 38 to enter the interior of the water collecting tank 36, so as to recycle the cleaning water, and the filter screen 38 will filter the cleaning water, wherein some of the dust inside the cleaning water will settle inside the overflow groove 37, and some of the dust will also accumulate on the upper surface of the filter screen 38, and while the first chain 27 and the second chain 33 are rotating, the outer surface of the winding shaft 25 will be driven by the transmission rod 24 to reel in and unwind the connecting rope 28,The winding directions of the connecting rope 28 on the outer surface of the winding shaft 25 at both ends of the two sets of transmission rods 24 are opposite, so the winding shaft 25 on the outer surface of the transmission rod 24 at one end of the transmission device 4 will unwind the connecting rope 28, and the winding shaft 25 on the outer surface of the transmission rod 24 at the other end of the transmission device 4 will synchronously rewind the connecting rope 28. In addition, the two ends of the cleaning scraper 29 are restricted inside the second limiting slide 40, so the cleaning scraper 29 will synchronously slide laterally according to the cleaning device 2, and the cleaning scraper 29 will scrape off the dust accumulated on the surface of the filter 38 to prevent the dust from clogging the filter 38. Therefore, by installing the cleaning device 2, the driving device 3, the transmission device 4 and the supporting device 5 on the outside of the photovoltaic panel 1, the outer surface of the photovoltaic panel 1 can be rotated and cleaned, and the bottom of the photovoltaic panel 1 can be cooled, and the clean water can be recycled.
