[0002] As a green renewable energy, photovoltaic energy plays an important role in energy revolution. Dust, dirt, bird droppings and other pollutants on the surface of photovoltaic panels can block sunlight and reduce the light energy absorbed by photovoltaic panels. For example, when there is a thin layer of dust on the surface of photovoltaic panels, it may cause a 10%-30% reduction in power generation efficiency. If not cleaned regularly, in areas with more dust, the power generation efficiency may even be reduced by more than 50%. This is because photovoltaic panels rely on absorbing photons in sunlight to generate electricity, and pollutants will reflect or absorb some photons, reducing the number of photons reaching the photovoltaic panel cells. Therefore, it is necessary to regularly clean the dust on the photovoltaic panels.

DETAILED DESCRIPTION

[0024] To make the purpose, technical scheme and advantages of the utility model clearer, the following will combine the specific embodiments of the utility model and the corresponding drawings to clearly and completely describe the technical scheme of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0025] The following will combine the drawings to specifically describe the technical scheme provided by each embodiment of the utility model.

[0026] Referring to Figures 1 to 5 The utility model embodiment provides a dustproof device for photovoltaic cleaning robot, including telescopic end's mounting rod 1, can adjust the distance between dust cleaning structure 2 and photovoltaic panel as required, the bottom of mounting rod 1 is equipped with connecting frame 11, and mounting rod 1 is rotatably connected between connecting frame 11;Connecting frame 11 is installed with two dust cleaning structures 2 that clean photovoltaic panel, and each dust cleaning structure 2 includes mounting shell 21 and cleaning rotating part 22 arranged on connecting frame 11, cleaning rotating part 22 is rotatably connected on mounting shell 21, and the outer wall of mounting shell 21 is equipped with detachable protective cover 3.

[0027] In the process of using, dust cleaning structure 2 can be installed on photovoltaic cleaning robot through mounting rod 1, and the dust on photovoltaic panel is cleaned through the working of photovoltaic cleaning robot, and the position of dust cleaning structure 2 can also be moved back and forth on photovoltaic panel through handheld mounting rod 1 to clean the dust on photovoltaic panel;

[0028] And the protective cover 3 can prevent the splash of cleaning water caused by the rotation of the dust cleaning structure 2 during the cleaning process from falling on the cleaned photovoltaic panel. During the cleaning of the photovoltaic panel, the photovoltaic panel is inclined downward, and the cleaning water flows downward along the inclination.

[0029] Specifically, the cleaning rotating member 22 includes a pneumatic motor 221, a rotating disc 222, and a plurality of cleaning soft strips 223. The pneumatic motor 221 is vertically arranged in the mounting shell 21. The rotating disc 222 is arranged on the rotating end of the pneumatic motor 221. The plurality of cleaning soft strips 223 are rotatably connected to the bottom of the rotating disc 222 at equal intervals. The cleaning soft strips 223 are detachably connected to the rotating disc 222. The rotating disc 222 is provided with two water outlets 226.

[0030] During the cleaning of the dust on the photovoltaic panel, the two water outlets 226 discharge cleaning water outward. Then, the pneumatic motor 221 works to drive the rotating disc 222 to rotate. The rotating disc 222 rotates to drive the plurality of cleaning soft strips 223 to rotate, thereby cleaning the dust on the photovoltaic panel. The cleaning water also quickly cleans and washes the photovoltaic panel during the rotation, which can better dissolve or flush away the dust, dirt, and other pollutants. The water spray can play a lubricating role to reduce the friction coefficient between the cleaning soft strips 223 and the surface of the photovoltaic panel.

[0031] During the cleaning process, if the cleaning soft strips 223 encounter some hard particles, such as sand particles, attached to the surface of the photovoltaic panel, the photovoltaic panel can be easily scratched in a dry state. Water spray can move these particles with the water flow, reducing the direct contact between the particles and the surface of the photovoltaic panel and the cleaning soft strips 223. At the same time, water can make the surface of the photovoltaic panel smoother, and the cleaning soft strips 223 can pass through more smoothly during rotation, thereby reducing the risk of scratching the photovoltaic panel.

[0032] Specifically, the top of each cleaning soft strip 223 is provided with a plug-in rod 224. The bottom of the rotating disc 222 is provided with a plug-in hole matched with the plug-in rod 224. The rotating disc 222 is provided with a locking screw 227 connected by threads. The plug-in rod 224 is provided with a threaded hole connected with the locking screw 227 by threads. The locking screw 227 and the plug-in rod 224 are arranged vertically.

[0033] If one or more of the cleaning soft strips 223 is broken during the cleaning process and needs to be replaced, the corresponding locking screw 227 can be loosened, the insertion rod 224 can be removed from the insertion hole, and then a new cleaning soft strip 223 can be inserted into the insertion hole, and the locking screw 227 can be tightened to connect the cleaning soft strip 223 to the rotating disc 222, thereby realizing the replacement of the cleaning soft strip 223, which is convenient and easy to operate.

[0034] Specifically, the protective cover 3 is provided with four connecting rods 31, and the protective cover 3 is inserted into the bottom of the mounting shell 21 through the four connecting rods 31. The protective cover 3 is provided with four screws for fixing to the protective cover 3. The four screws are used to disassemble and assemble the protective cover 3 from the mounting shell 21, and the four connecting rods 31 are used for positioning when the protective cover 3 is installed.

[0035] The bottom of the protective cover 3 is also provided with a rubber ring, which will not damage the photovoltaic panel during movement on the photovoltaic panel.

[0036] The arrangement of the protective cover 3 ensures that the cleaning water will not splash around during the cleaning process, and the cleaning water will not splash onto the cleaned photovoltaic panel due to the effect of centripetal force, which will affect the cleaning effect of the photovoltaic panel.

[0037] Specifically, the inner wall of the protective cover 3 is provided with a plurality of equally spaced scraping strips 32; the scraping strips 32 are made of rubber material.

[0038] During the cleaning process of the photovoltaic panel by the rotating disc 222, the cleaning soft strips 223 will also contact the rubber scraping strips 32 in the protective cover 3, and mutual friction will occur between them, which will scrape off the dirt adhered to the cleaning soft strips 223, prevent the dirt from adhering and wrapping around the cleaning soft strips 223 after a long period of use, and also prevent the damage to the photovoltaic panel caused by the friction of the cleaning soft strips 223.

[0039] Specifically, the middle position of the rotating disc 222 is provided with a connecting plate 4, and the connecting plate 4 is provided with a scraping strip 41 matched with the insertion. The scraping strip 41 is made of natural rubber material and can be pulled out of the connecting plate 4 for replacement after use.

[0040] The connecting plate 4 will also rotate during the rotation of the rotating disc 222, and the rotation of the connecting plate 4 will drive the position of the scraping strip 41 to rotate, which will scrape off the dust on the photovoltaic panel, so that the cleaning of the photovoltaic panel is more thorough and cleaner.

[0041] The above merely describes the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
