[0037] By adopting the above technical solution, when cleaning the photovoltaic panel 200, the cleaning assembly 100 moves along the photovoltaic support 300; during the movement, the motor drives the cleaning roller 10 to rotate, and the bristles on the outer surface of the cleaning roller 10 clean the surface of the photovoltaic panel 200. Since a water diversion row 6 is respectively provided on both sides of the cleaning roller 10, through the above arrangement, the photovoltaic panel 200 is first spray-cleaned, and then cleaned a second time using the cleaning roller 10; then the water diversion row 6 located on the rear side of the cleaning roller 10 rinses the photovoltaic panel 200 again.

[0040] A disc is provided on the outer side of the water adding nozzle 47. When the driving shell 146 floats up, the disc can be pushed upward, thereby lifting the water adding nozzle 47 and the water adding tank 41.

[0041] By adopting the above technical solution, when adding water to the water tank body 141, the water tank 41 moves downward so that the water adding nozzle 47 is aligned with the conical top cover 144, and the conical top cover 144 lifts the water blocking ball 48. When the water blocking ball 48 is separated from the conical mouth, the space around the water blocking ball 48 increases, and water flows from the outside of the water blocking ball 48 to the conical top cover 144 and then enters the water inlet pipe 142 through the through grooves around the conical top cover 144, and then enters the water tank body 141 through the through grooves around the water outlet bottom shell 143; When the water tank body 141 is filled with water, the floating plate 145 floats up, driving the driving shell 146 to float up, thereby lifting the water adding tank 41; making the water adding nozzle 47 separate from the conical top cover 144; under the elastic force of the spring 49, the water blocking ball 48 is blocked at the conical opening, so as to achieve the effect of blocking the water in the water adding tank 41.

[0042] In this embodiment, the water outlet bottom shell 143 is plastic welded inside the water tank body 141; the water inlet pipe 142, the water outlet bottom shell 143 and the conical top cover 144 are integrally injection molded, and a plurality of through grooves are arranged in an annular array on the upper surface of the conical top cover 144 and the upper surface of the water outlet bottom shell 143.

[0043] Specifically, the driving shell 146 is slidably connected to the water inlet of the water tank body 141; this can enable the driving shell 146 to slide straight up and down.

[0044] Please refer to the attached Figure 7 and Figure 8 In this embodiment, both ends of the cleaning roller 10 are installed in cooperation with the frame body 1 through pedestal bearings, and one end is also connected to the motor in cooperation; a protective shell 11 is also sleeved on the upper side of the cleaning roller 10, and both ends of the protective shell 11 are fixed to the frame body 1.

[0045] By adopting the above technical solution, the setting of the protective shell 11 can prevent the situation of muddy water splashing when the cleaning roller 10 cleans the photovoltaic panel 200.

[0046] In this embodiment, cross beams 3 fixed to the frame body 1 are also provided on both sides of the cleaning roller 10; the cross beams 3 are used for fixing the Z-shaped plate 9, and a plurality of L-shaped brackets 4 are fixed on the top of each cross beam 3; a solar panel 5 is fixed on the top of the plurality of L-shaped brackets 4; The solar panel 5 is electrically connected to a battery pack 13 arranged in the auxiliary frame 12 through a wire; the battery pack 13 is also electrically connected to a controller 19. A rain shield (not shown) is also provided above the battery pack 13.

[0047] By adopting the above technical solution, the electric energy converted by the solar panel 5 is stored in the battery pack 13, so as to facilitate the power consumption of the entire cleaning device.

[0048] In addition, it should be noted that, according to the laying length of the photovoltaic panel 200 and the power consumption of the entire cleaning device, a suitable storage capacity of the battery pack 13 is selected to ensure that the battery pack 13 has enough electric energy to clean the photovoltaic panel 200.

[0049] According to the rainfall or the number of sunny days in the actual photovoltaic panel installation area, it is reasonably selected whether to set up a charging component; to prevent the situation of insufficient electric energy in continuous rainy days.

[0050] Please see attached Figure 7 In this embodiment, the controller 19 is fixed on the inner side of the frame body 1, and a water pump 15 is provided on one side of the controller 19; the water inlet of the water pump 15 is connected to the water tank 14 through a pipeline, and the water outlet of the water pump 15 is connected to the water distribution drain 6 through a pipeline; the water pump 15 is also electrically connected to the battery pack 13.

[0051] By adopting the above technical solution, the battery pack 13 provides electrical energy for the water pump 15; the controller 19 controls the opening and closing of the water pump 15, thereby realizing the water supply of the water distribution row 6, and then the water distribution row 6 disperses the water into multiple water distribution pipes 7, and then sprays it out from the high-pressure nozzle 8, thereby realizing the flushing of the photovoltaic panel 200.

[0052] Please see attached Figure 7 , Figure 8 and Figure 15 In this embodiment, two driving assemblies 16 are symmetrically provided on the frame body 1, and a protective cover 17 is buckled on the outer side of the driving assembly 16; the driving assembly 16 includes a reduction gear unit 161 fixed to the frame body 1, and the reduction gear unit 161 is transmission-connected to a transmission shaft 162; the transmission shaft 162 is transmission-connected to a driving wheel 164 through a bevel gear unit 163.

[0053] To be more specific, the reduction gear unit 161 is composed of a motor and a reduction gear; the bevel gear unit 163 is composed of two bevel gears, one of which is mounted on the transmission shaft 162, and the other is coaxially arranged with the driving wheel 164 and fixed to the frame body 1 through a seat bearing; the lower end of the driving wheel 164 is attached to the upper surface of the photovoltaic panel 200.

[0054] By adopting the above technical solution, two of the four guide wheels 2 are grouped together and respectively engaged in the guide grooves on both sides of the photovoltaic bracket 300. The reduction gear unit 161 drives the transmission shaft 162 to rotate, and drives the driving wheel 164 to rotate with the cooperation of the bevel gear unit 163. Since the lower end of the driving wheel 164 is attached to the upper surface of the photovoltaic panel 200, the entire cleaning assembly 100 can move along the photovoltaic bracket 300 and clean the photovoltaic panel 200.

[0055] In this embodiment, the cleaning component 100 moves along the photovoltaic support 300 and cleans the photovoltaic panel 200 disposed on the photovoltaic support 300 ; a water adding mechanism 400 for adding water to the cleaning component 100 is also installed at one end of the photovoltaic support 300 .

[0056] Please see attached Figure 11 and Figure 12, in this embodiment, an L-shaped driving rod 45 is fixed to one side of the water adding tank 41 close to the guide rod 42. The bottom of the L-shaped driving rod 45 is inclined and is slidably connected to the top block assembly 46; The top block assembly 46 includes a wedge-shaped top block 461, and two sliding rods 462 are welded to one side of the wedge-shaped top block 461; the sliding rods 462 are slidably connected to the support 463; a return spring 464 is also sleeved on the sliding rods 462; the return spring 464 is located between the wedge-shaped top block 461 and the support 463.

[0057] Specifically, a top rod 18 is also fixed to one side of the frame body 1 close to the wedge-shaped top block 461; when the frame body 1 approaches the wedge-shaped top block 461, the top rod 18 pushes the wedge-shaped top block 461 to one side.

[0058] By adopting the above technical solution, after the cleaning assembly 100 finishes cleaning the photovoltaic panel 200 along the photovoltaic bracket 300, it needs to return for water addition; when the cleaning assembly 100 travels to the water adding mechanism 400, the top rod 18 on the outer side of the auxiliary frame 12 will push the wedge-shaped top block 461 to one side, forcing the wedge-shaped top block 461 to separate from the bottom of the L-shaped driving rod 45. The water tank body 141 slides down along the guide rod 42 under the action of gravity, so as to be accurately docked with the conical top cover 144, and start to add water into the water tank body 141.

[0059] After the water addition is completed, the driving shell 146 lifts the water adding tank 41 under the action of buoyancy. After the water adding nozzle 47 is separated from the conical top cover 144, the cleaning assembly 100 moves as a whole. At this time, the top rod 18 will lose the top force on the wedge-shaped top block 461; the wedge-shaped top block 461 resets under the elastic force of the return spring 464; the water adding tank 41 is supported again through the L-shaped driving rod 45; for the next water adding action.

[0060] It should be noted that since the water storage tank 14 in the cleaning assembly 100 is in a long-term active state, only replenishment water addition can be carried out; while the position of the water adding tank 41 is fixed, water can be added into the water adding tank 41 by means of the cooperation of a water level sensor and an electromagnetic valve. This water adding method is a mature technology, and its specific principle will not be elaborated here.

[0061] The working principle of the present invention is: when cleaning the photovoltaic panel 200, the cleaning assembly 100 moves along the photovoltaic bracket 300; during the movement, the motor drives the cleaning roller 10 to rotate, and the bristles on the outer surface of the cleaning roller 10 clean the surface of the photovoltaic panel 200; Since a water diversion row 6 is respectively provided on both sides of the cleaning roller 10, through the above arrangement, the photovoltaic panel 200 is first spray-cleaned, and then the cleaning roller 10 is used for secondary cleaning; then the water diversion row 6 located at the rear side of the cleaning roller 10 rinses the photovoltaic panel 200 again. This cleaning method can not only clean the dirt and bird droppings on the photovoltaic panel 200, but also avoid dust during the cleaning process; After the cleaning assembly 100 has finished cleaning the photovoltaic panel 200 along the photovoltaic bracket 300, it needs to return to add water; when the cleaning assembly 100 moves to the water adding mechanism 400, the top rod 18 on the outside of the auxiliary frame 12 will push the wedge-shaped top block 461 to one side, forcing the wedge-shaped top block 461 to separate from the bottom of the L-shaped driving rod 45, and the water tank body 141 slides downward along the guide rod 42 under the action of gravity, so as to accurately dock with the conical top cover 144, and the conical top cover 144 lifts the water blocking ball 48. When the water blocking ball 48 is separated from the conical mouth, the space around the water blocking ball 48 increases, and water flows from the outside of the water blocking ball 48 to the conical top cover 144 and then enters the water inlet pipe 142 from the through grooves around the conical top cover 144, and then enters the water tank body 141 through the through grooves around the water outlet bottom shell 143; When the water in the water tank body 141 is filled with water, the floating plate 145 floats up, driving the driving shell 146 to float up, thereby lifting the water tank 41; the water filling nozzle 47 is separated from the conical top cover 144; under the elastic force of the spring 49, the water blocking ball 48 is blocked at the conical mouth, thereby achieving the effect of blocking the water in the water tank 41; The cleaning assembly 100 moves as a whole, at which time the push rod 18 loses its push force on the wedge-shaped push block 461; the wedge-shaped push block 461 is reset under the elastic force of the reset spring 464; the water tank 41 is re-supported by the L-shaped drive rod 45; so as to facilitate the next water adding action.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
