[0002] In the rainy and snowy weather in winter, there is usually a certain amount of snow accumulated on the surface of the photovoltaic panel. This snow will produce a hot plate effect and seriously affect the photovoltaic panel's photoelectric conversion efficiency, so cleaning the snow on the photovoltaic panel is indispensable.

[0040] like Figure 1 As shown, this embodiment provides a photovoltaic panel array 100, and a cleaning robot 200 is placed on the surface of the photovoltaic panel array 100. The cleaning robot 200 works on the photovoltaic panel, has good grip, and can move on an inclined plane. At the same time, the cleaning robot 200 is located at the starting position. When the cleaning robot 200 moves, the cleaning robot 200 can move in the horizontal direction, so that its cleaning device can cover the entire photovoltaic panel array 100 during the moving process.

[0041] like Figure 1 , Figure 2 as well as Figure 3As shown, this embodiment also provides a traction device 300, which specifically includes four traction shafts 301, each of which is located at a corner of the photovoltaic panel array 100. The traction device 300 also includes two traction ropes 302, which divide the four traction shafts 301 into two groups according to the direction of travel of the cleaning robot 200, and each traction rope 302 is sleeved on the outer surface of a group of traction shafts 301. Each traction shaft 301 can rotate at the same speed and direction, so that any section of the traction rope 302 can move horizontally. Each traction rope 302 is connected to the cleaning robot 200 through a connection end 201 located on both sides of the cleaning robot 200, so that the traction rope 302 and the cleaning robot 200 can be displaced synchronously. The function of the traction device 300 is that the traction device 300 can indirectly provide power to the cleaning robot 200 through the power provided by the traction shaft 301, thereby assisting the movement of the cleaning robot 200. At the same time, the pulling force of the traction rope 302 on the cleaning robot 200 enables the cleaning robot 200 to move on the preset travel track, and the traction device 300 can prevent the cleaning robot 200 from deviating from the preset travel track.

[0042] like Figure 1 as well as Figure 4 As shown, the cleaning robot 200 includes a body 1, which includes a substrate 11, two oppositely arranged baffles 12 and two oppositely arranged boxes 13.

The transmission direction of the crawler 23 forms an angle with the cleaning plate 24 , and the angle ranges from 60 to 90 degrees. In this embodiment, 90 degrees is preferred. The cleaning plate 24 is vertically connected to the outer surface of the crawler 23 .

[0044] When the cleaning robot 200 is working on the surface of the photovoltaic panel, the rotating wheel motor 21 of the first cleaning device 2 drives the rotating wheel 22 to rotate, so that the track 23 can rotate continuously, so that the track 23 can drive the cleaning board 24 to continuously scrape the snow on the photovoltaic panel, so that the snow on the photovoltaic panel can be pushed down from both sides of the photovoltaic panel by the cleaning board 24, so that the cleaning robot 200 can clear the accumulated snow on the photovoltaic panel, thereby improving the user experience.

[0045] like Figure 1 , Figure 4 , Figure 6 as well as Figure 7 As shown, the cleaning robot 200 also includes a traveling device 3, each of which is arranged at the bottom of the vehicle body 1. The traveling device 3 includes two first wheels 31, a wheel motor 32 and a transmission device 36 at one end of the cleaning robot 200. The vehicle body 1 also includes a first fixed frame 14, the first fixed frame 14 is fixedly connected to the base plate 11, and is fixedly connected to the two baffles 12. The first fixed frame 14 is located at one end of the lower side of the base plate 11 and is located between the two baffles 12. One side of the first fixed frame 14 is arranged opposite to the surface of one side of a box 13 facing the other box 13. Each first wheel 31 includes a first wheel axle 311, one end of each first wheel axle 311 passes through a side wall of a box 13 and extends to the inside of the box 13, and the other end of each first wheel axle 311 is rotatably connected to the first fixed frame 14. The wheel motor 32 is mounted on one side of the housing 13 facing the other housing 13, and includes a power output shaft, so that the power output shaft 321 of the wheel motor 32 passes through a side wall of the housing 13 and extends into the interior of the housing 13. The first wheel 31 is connected to the wheel motor 32 through a transmission device 36.

[0046] The transmission device 36 includes two first gears 312, a second gear 322 and a transmission belt 34.

The second gear 322 is disposed inside the housing 13, and the second gear 322 is connected to the power output shaft 321 of the wheel motor 32. The transmission belt 34 is sleeved on the outer surfaces of the first gear 312 and the second gear 322, and a toothed ring is disposed on the inner wall of the transmission belt 34, which meshes with the first gear 312 and the second gear 322.

[0047] The first fixing frame 14 is used to fix a pair of baffles 12 to enhance the stability and rigidity of the vehicle body 1, and to enable the first wheel axle 311 to be rotatably mounted to the first fixing frame 14, so that the first wheel 31 can stably move on the edge of the photovoltaic panel. At the same time, the outer surface of the first wheel 31 is tangent to the outer surface of the photovoltaic panel, so that when the first wheel 31 is driven to rotate, the cleaning robot 200 can move on the surface of the photovoltaic panel.

[0048] The traveling device 3 includes at least one second wheel 33, at least one third gear 332 and at least one fourth gear 333. Each second wheel 33 includes a second wheel axle 331, one end of each second wheel axle 331 passes through the bottom of a box 13 and extends into the box 13. The traveling direction of each second wheel 33 is perpendicular to the extending direction of the base plate 11, and the extending direction of each second wheel axle 331 is perpendicular to the extending direction of the base plate 11. Each third gear 332 is arranged inside the box 13, each third gear 332 is sleeved on the outer surface of the first wheel axle 311, and rotates coaxially with the first wheel axle 311. Each fourth gear 333 is arranged inside the box 13, each fourth gear 333 is sleeved on the outer surface of the second wheel axle 331, and rotates coaxially with the second wheel axle 331. Each fourth gear 333 is meshed with a third gear 332. When the cleaning robot 200 is working, the outer surface of each second wheel 33 is tangent to the frame of the photovoltaic panel, and the second wheel 33 rotates synchronously with the first wheel 31 through the third gear 332 and the fourth gear 333. When the second wheel 33 is driven by the first wheel 31, the second wheel 33 can move along the frame of the photovoltaic panel, fix the travel route of the cleaning robot 200, and prevent the cleaning robot 200 from sliding off the photovoltaic panel.

[0049] like Figure 1 , Figure 4 , Figure 6 , Figure 8 as well as Fig. 9As shown, the traveling device 3 includes two first wheels 31, a wheel motor 32 and a transmission device 36 at the other end of the cleaning robot 200, and the transmission device 36 includes two first gears 312, a second gear 322 and a transmission belt 34. The vehicle body 1 also includes a second fixing frame 15, which is fixedly connected to the base plate 11 and fixedly connected to the two baffles 12. The second fixing frame 15 is located in the middle of the lower side of the base plate 11 and between the two baffles 12. One side of the second fixing frame 15 is arranged opposite to the surface of one side of a box 13 facing the other box 13. Each first wheel 31 includes a first wheel axle 311, one end of each first wheel axle 311 passes through a side wall of a box 13 and extends to the inside of the box 13, and the other end of each first wheel axle 311 is rotatably connected to the second fixing frame 15. The installation method of the wheel motor 32, the two first gears 312, the second gear 322 and the transmission belt 34 is the same as the former.

[0050] The second fixing frame 15 is used to fix a pair of baffles 12 to enhance the stability and rigidity of the vehicle body 1, and enables the first wheel axle 311 to be rotatably mounted to the second fixing frame 15, so that the first wheel 31 can stably move on the edge of the photovoltaic panel. At the same time, the first wheel axle 311 is also connected to the third wheel 35 through the second fixing frame 15, so that the third wheel 35 can also rotate coaxially with the first wheel axle 311. When the first wheel axle 311 rotates, the first wheel 31 and the third wheel 35 can move along the surface of the photovoltaic panel to prevent the cleaning robot 200 from slipping off the photovoltaic panel.

[0051] The traveling device 3 includes two third wheels 35 , each of which is sleeved on the outer surface of a first axle 311 , so that each of the third wheels 35 is located between one end of the first axle 311 and the second fixing frame 15 , and each of the third wheels 35 rotates coaxially with a first axle 311 .

[0052] like Figure 1 , Figure 4 as well as Figure 6As shown, the cleaning robot 200 also includes a second cleaning device 4, which includes a rotating shaft 41, a fifth gear 42 and a roller brush 43. One end of the rotating shaft 41 passes through a side wall of a box 13 and extends to the inside of the box 13, and the other end of the rotating shaft 41 is rotatably connected to the second fixing frame 15. The fifth gear 42 is arranged inside the box 13, and the fifth gear 42 is meshed with the transmission belt 34. The roller brush 43 is sleeved on the outer surface of the rotating shaft 41. When the cleaning plate 24 continues to scrape the snow on the photovoltaic panel, so that the snow on the photovoltaic panel can be pushed down from both sides of the photovoltaic panel by the cleaning plate 24, the roller brush 43 can also perform secondary cleaning on the photovoltaic panel. The function of the roller brush 43 is that when the first cleaning device 2 sweeps the large pieces of snow from the photovoltaic panel, there are still small pieces of snow remaining on the surface of the photovoltaic panel. At this time, a cleaning tool such as a roller brush 43 that can fully fit the photovoltaic panel is needed to clean the small snow to complete the full cleaning of the photovoltaic panel.

[0053] like Figures 1 to 9 As shown, in an actual situation, when the cleaning robot 200 works on the surface of the photovoltaic panel, the wheel motor 32 starts to work, and the power output shaft 321 of the wheel motor 32 drives the second gear 322 to rotate. Since each second gear 322 rotates synchronously with the two first gears 312 and a fifth gear 42 through the transmission belt 34, the wheel motor 32 can drive the first wheel 31 and the roller brush 43 of the first cleaning device 2 to rotate. At the same time, since each second wheel 33 rotates synchronously with a first wheel 31 through the third gear 332 and the fourth gear 333, and each third wheel 35 is sleeved on the outer surface of a first wheel shaft 311, the wheel motor 32 can synchronously drive the second wheel 33 and the third wheel 35 to rotate, so that the cleaning robot 200 can travel on the photovoltaic panel array 100.

[0054] When the cleaning robot 200 moves on the surface of the photovoltaic panel, the rotating wheel motor 21 of the first cleaning device 2 drives the rotating wheel 22 to rotate, so that the track 23 can rotate continuously, so that the track 23 can drive the cleaning board 24 to continuously scrape the snow on the photovoltaic panel, so that the snow on the photovoltaic panel can be pushed down from both sides of the photovoltaic panel by the cleaning board 24, so that the cleaning robot 200 can clear the accumulated snow on the photovoltaic panel.

[0055] The advantage of this embodiment is that it provides a cleaning robot, which includes a traveling device and a first cleaning device, and the first cleaning device is connected to one side of the vehicle body's own traveling direction. When the cleaning robot works on the surface of the photovoltaic panel, the rotating wheel motor of the first cleaning device drives the rotating wheel to rotate, so that the track can continue to rotate, so that the track can drive the cleaning plate to continuously scrape the snow on the photovoltaic panel, so that the snow on the photovoltaic panel can be pushed off from both sides of the photovoltaic panel by the cleaning plate, so that the cleaning robot can clear the snow on the photovoltaic panel, thereby improving the user experience.

[0056] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work.
