In the embodiment of the present application, the upper surface 11 of the photovoltaic panel 10 refers to the surface of the side of the photovoltaic panel 10 facing the sun, that is, the surface of the photovoltaic panel 10 that absorbs light energy. In the embodiment of the present application, the photovoltaic panel 10 includes a first end and a second end arranged relatively to each other along a first direction, and in the direction of gravity, the first end of the photovoltaic panel 10 is higher than the second end of the photovoltaic panel 10. More specifically, the first end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is farther from the installation surface, and the second end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is closer to the installation surface. In the embodiment of the present application, the side surface 12 of the first end of the photovoltaic panel 10 refers to the surface where the first end of the photovoltaic panel 10 is connected to the upper surface 11 of the photovoltaic panel 10.

[0023] Please refer to Figures 1 to 4 The photovoltaic panel cleaning device provided in the embodiment of the present application is used to clean foreign objects from the photovoltaic panel 10. The photovoltaic panel 10 includes a first end and a second end opposite to each other along a first direction. In the direction of gravity, the first end of the photovoltaic panel 10 is higher than the second end of the photovoltaic panel 10. The photovoltaic panel cleaning device includes a first rolling assembly 100, a second rolling assembly 200 and a cleaning assembly 300. The first rolling assembly 100 is arranged at the first end of the photovoltaic panel 10, and the second rolling assembly 200 is arranged at the second end of the photovoltaic panel 10.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The cleaning assembly 300 includes a mounting frame 310, a chain 320, a first sprocket 330, a second sprocket 340 and a cleaning member 350; the first rolling assembly 100 and the second rolling assembly 200 are respectively fixed to opposite ends of the mounting frame 310; the first sprocket 330 is arranged on a side of the mounting frame 310 close to the first rolling assembly 100, and the second sprocket 340 is arranged on a side of the mounting frame 310 close to the second rolling assembly 200, the chain 320 is meshed with the first sprocket 330 and the second sprocket 340, and the cleaning member 350 is fixed to a side of the chain 320 facing the upper surface 11 of the photovoltaic panel 10; the first sprocket 330 and the second sprocket 340 can drive the chain 320 to rotate so that the cleaning member 350 can clean the upper surface 11 of the photovoltaic panel 10, and the rotation trajectory of the cleaning member 350 is parallel to the upper surface 11 of the photovoltaic panel 10.

[0025] refer to Figure 4 The mounting frame 310 is provided with dust exhaust ports 311 at both opposite ends along the first direction. The dust exhaust ports 311 extend out of the photovoltaic panel 10 along the first direction. The dust exhaust ports 311 face the photovoltaic panel 10 , and the rotation trajectory of the cleaning member 350 passes through the two dust exhaust ports 311 .

[0026] Please refer to Figure 2 and Figure 4 In the embodiment of the present application, the first sprocket 330 and the second sprocket 340 are both arranged parallel to and spaced from the upper surface 11 of the photovoltaic panel 10, that is, the rotation planes of the first sprocket 330 and the second sprocket 340 are both parallel to the upper surface 11 of the photovoltaic panel 10, and the chain 320 is meshed with the first sprocket 330 and the second sprocket 340, so the plane where the rotation track of the chain 320 is located is also parallel to the upper surface 11 of the photovoltaic panel 10. It can be understood by those skilled in the art that in the present application, the plane where the rotation track of the chain 320 is located is parallel to the upper surface 11 of the photovoltaic panel 10, but in practice, the chain 320 will have a certain deviation due to gravity or installation errors, that is, in practice, it will not be absolutely parallel.

[0027] In the embodiment of the present application, the cleaning member 350 is fixedly connected to the side of the chain 320 facing the upper surface 11 of the photovoltaic panel 10. Obviously, the side of the cleaning member 350 facing the upper surface 11 of the photovoltaic panel 10 should be in contact with the upper surface 11 of the photovoltaic panel 10, so that when the cleaning member 350 rotates with the chain 320, the cleaning member 350 can clean the dust, snow, etc. on the upper surface 11 of the photovoltaic panel 10. When the cleaning member 350 rotates with the chain 320 to clean the upper surface 11 of the photovoltaic panel 10, when the cleaning member 350 rotates to the dust exhaust port 311, since the dust exhaust port 311 extends beyond the photovoltaic panel 10 along the first direction, the dust cleaned by the cleaning member 350 will also be driven by the cleaning member 350 to a position beyond the photovoltaic panel 10 along the first direction. At this time, under the action of gravity, the dust or snow cleaned by the cleaning member 350 will fall from the dust exhaust port 311 to the ground, thereby preventing foreign objects such as dust and snow from being lifted up and falling on the photovoltaic panel 10 again, thereby improving the cleaning effect.

[0028] Those skilled in the art can also understand that there can be multiple cleaning members 350, and multiple cleaning members 350 are arranged at intervals on the chain 320. The specific number of cleaning members 350 can be set by those skilled in the art according to actual conditions, and the embodiment of the present application does not make any specific limitation.

[0029] Please refer to Figure 2 and Figure 3 In some embodiments, the mounting frame 310 includes a first support beam 312, a second support beam 313, a first fixing plate 314, and a second fixing plate 315; the first support beam 312 and the second support beam 313 are arranged in parallel and spaced apart, the opposite ends of the first support beam 312 extend out of the photovoltaic panel 10 along the first direction, and are fixedly connected to the first rolling assembly 100 and the second rolling assembly 200, and the opposite ends of the second support beam 313 extend out of the photovoltaic panel 10 along the first direction, and are fixedly connected to the first rolling assembly 1 00 and the second rolling assembly 200; the first fixing plate 314 is fixedly connected to the first support beam 312 and the second support beam 313, and the first fixing plate 314 is located on the side close to the first rolling assembly 100, and the first sprocket 330 is arranged on the side of the first fixing plate 314 facing the photovoltaic panel 10; the second fixing plate 315 is fixedly connected to the first support beam 312 and the second support beam 313, and the second fixing plate 315 is located on the side close to the second rolling assembly 200, and the second sprocket 340 is arranged on the side of the second fixing plate 315 facing the photovoltaic panel 10. The use of the first support beam 312 and the second support beam 313 can reduce the weight of the mounting frame 310, thereby preventing the cleaning equipment from damaging the photovoltaic panel 10 due to excessive weight.

[0030] Those skilled in the art can understand that the opposite ends of the first support beam 312 and the opposite ends of the second support beam 313 both extend out of the photovoltaic panel 10 along the first direction, and the gap between the first support beam 312 and the second support beam 313 extending out of the photovoltaic panel 10 forms a dust exhaust port 311.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the mounting frame 310 further includes a first track beam 316 and a second track beam 317, wherein the first track beam 316 is fixedly connected to the first support beam 312, and the second track beam 317 is fixedly connected to the second support beam 313; a first slideway 3161 is provided on the side of the first track beam 316 facing the photovoltaic panel 10, and the first slideway 3161 penetrates the first track beam 316 along the first direction; a second slideway 3171 is provided on the side of the second track beam 317 facing the photovoltaic panel 10, and the second slideway 3171 penetrates the second track beam 317 along the first direction; a part of the chain 320 is located in the first slideway 3161 and the second slideway 3171. In the embodiment of the present application, by providing the first slideway 3161 and the second slideway 3171, the running track of the chain 320 can be ensured to be stable, thereby ensuring the stable running of the cleaning member 350, thereby improving the cleaning effect.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the first slide 3161 and the second slide 3171 both include a receiving cavity 3162 and an avoidance cavity 3163 that are interconnected along the direction from the first support beam 312 to the photovoltaic panel 10. The chain 320 includes a first chain plate group 321 and a second chain plate group 322 that are relatively arranged, and a roller group 323 connected between the first chain plate group 321 and the second chain plate group 322. The first chain plate group 321 is located in the receiving cavity 3162, and the first chain plate group 321 contacts the bottom wall of the receiving cavity 3162 on one side close to the avoidance cavity 3163. The roller group 323 extends from the side of the avoidance cavity 3163 away from the receiving cavity 3162 and is connected to the second chain plate group 322. The cleaning member 350 is fixedly connected to the side of the second chain plate group 322 away from the first chain plate group 321. With such arrangement, the weight of the chain 320 and the cleaning member 350 can be borne by the bottom wall of the accommodating cavity 3162, thereby preventing the chain 320 and the cleaning member 350 from falling due to gravity. In this way, it can be ensured that the pressure applied by the cleaning member 350 to the upper surface 11 of the photovoltaic panel 10 is consistent, thereby avoiding damage to the photovoltaic panel 10 during the cleaning process and ensuring the service life of the photovoltaic panel 10.

[0033] Those skilled in the art can understand that the first chain plate group 321 and the second chain plate group 322 and the roller group 323 of the chain 320 can be easily disassembled and assembled. Therefore, in the process of installing the chain 320 to the first slide 3161, the first sprocket 330, the second slide 3171 and the second sprocket 340, the chain 320 can be disassembled first and then installed, which can facilitate the installation of the chain 320.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the cleaning assembly 300 further includes a connecting plate 360, and the cleaning member 350 is fixedly connected to the side of the second chain plate group 322 away from the first chain plate group 321 through the connecting plate 360. Fixing the cleaning member 350 by the connecting plate 360 ​​can facilitate the adjustment of the position of the cleaning member 350 and the installation of the cleaning member 350. It can be understood by those skilled in the art that the cleaning member 350 may include a brush and a soft plate, etc., and the brush and the soft plate may be arranged alternately and spaced on the side of the second chain plate group 322 away from the first chain plate group 321. The soft plate may be made of rubber. The brush can remove dust, and the soft plate can remove snow. The brush and the soft plate are simultaneously arranged on the second chain plate group 322, so that the cleaning device can take into account the removal of dust and snow.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the photovoltaic panel cleaning device further includes a reinforcing plate 370, and the reinforcing plate 370 is fixedly connected to the first support beam 312 and the second support beam 313; the first track beam 316 and the second track beam 317 are respectively fixedly connected to the side of the reinforcing plate 370 facing the photovoltaic panel 10. It can be understood by those skilled in the art that a plurality of reinforcing plates 370 can be provided, and the plurality of reinforcing plates 370 are arranged at intervals along the first direction. By providing the reinforcing plate 370, deformation of the first support beam 312 and the second support beam 313 can be avoided. In the embodiment of the present application, the first track beam 316 and the second track beam 317 can also be fixedly connected to the side of the reinforcing plate 370 facing the photovoltaic panel 10, so that the positions of the first track beam 316 and the second track beam 317 can be flexibly adjusted to adapt to the rotation trajectory of the chain 320, which is convenient for installation.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the photovoltaic panel cleaning device further includes a drive motor 380, which is fixed to the first fixed plate 314 and used to drive the first sprocket 330, or the drive motor 380 is fixed to the second fixed plate 315 and used to drive the second sprocket 340. It will be appreciated by those skilled in the art that hydraulic drive or pneumatic drive may also be used. In the embodiment of the present application, the drive motor 380 may be used to drive the first sprocket 330 or the second sprocket 340, which is not limited here. It will also be appreciated by those skilled in the art that the drive motor 380 may drive the chain 320 to rotate in a clockwise direction, such as Figure 4 As shown, the driving motor 380 can also drive the chain 320 to rotate counterclockwise, which is not specifically limited in the embodiment of the present application.

[0037] In some embodiments, the first rolling assembly 100 and the second rolling assembly 200 can move along the second direction on the upper surface 11 of the photovoltaic panel 10 to drive the cleaning assembly 300 to move along the second direction on the upper surface 11 of the photovoltaic panel 10, and the second direction is perpendicular to the first direction. It can be understood by those skilled in the art that, since the area of ​​the photovoltaic panel 10 is generally large, in the process of cleaning the upper surface 11 of the photovoltaic panel 10, the cleaning member 350 needs to move along the second direction, so as to ensure that the cleaning member 350 can completely clean the upper surface 11 of the photovoltaic panel 10. In the embodiment of the present application, the movement of the first rolling assembly 100 and the second rolling assembly 200 drives the movement of the cleaning assembly 300, so that the cleaning assembly 300 can fully clean the upper surface 11 of the photovoltaic panel 10, thereby improving the automation capability of the cleaning equipment.

[0039] The two side wheels 120 are respectively connected to the first mounting plate 110, and both side wheels 120 can roll on the side 12 of the first end of the photovoltaic panel 10. By providing two side wheels 120, the cleaning device can be hung on the photovoltaic panel 10 without adding additional supporting equipment, and the structure is simple and practical.

[0040] The first rolling assembly 100 also includes two first walking wheels 130, and the second rolling assembly 200 also includes two second walking wheels 220; the cleaning assembly 300 is fixedly connected to the second mounting plate 210 at one end away from the first mounting plate 110; the two first walking wheels 130 are both connected to the first mounting plate 110, and the two first walking wheels 130 can roll along the upper surface 11 of the first end of the photovoltaic panel 10; the two second walking wheels 220 are both connected to the second mounting plate 210, and the two second walking wheels 220 can roll along the upper surface 11 of the second end of the photovoltaic panel 10. Those skilled in the art can understand that, the two first walking wheels 130 are respectively located on both sides of the cleaning component 300, and the two second walking wheels 220 are also respectively located on both sides of the cleaning component 300. More specifically, the interval between the two first walking wheels 130 is equal to the interval between the two second walking wheels 220, and one end of the cleaning component 300 is fixed in the middle of the two first walking wheels 130, and the other end of the cleaning component 300 is fixed in the middle of the two second walking wheels 220.
