Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structures for serving new energy, and particularly relates to a cleaning device with adjustable force applied to a solar panel. Background Art

[0002] With the global warming and the increasing awareness of environmental protection, replacing traditional energy with clean energy has become a major emerging trend. In recent years, photovoltaic power generation has played an increasingly important role. However, at the same time, the power generation efficiency of large-scale solar panels has decreased significantly due to the serious influence of dust accumulation, bird droppings, etc., and the problem of solar panel cleaning management needs to be solved urgently.

[0003] Dust pollution on the surface of the power generation board of a solar panel assembly will significantly reduce its power generation efficiency and service life. Due to the differences in installation locations and the characteristics of dust types, solar panel cleaning robots should have different modes to adapt to different application scenarios. However, currently, the solar panel cleaning robots on the market generally adopt a single force mode for cleaning, and this design method cannot be adapted to a variety of complex environmental conditions.

[0004] Specifically, when the cleaning force is small, the robot will not be able to effectively remove the stubborn dirt on the surface of the solar panel, thus affecting the power generation efficiency of the solar panel, with low cleaning efficiency and increased time cost. On the contrary, if the cleaning force is too strong, it will not only cause the coating or material on the surface of the solar panel to be worn, but even damage the photovoltaic glass, reducing the service life while increasing the maintenance cost. In addition, excessive cleaning force will also cause unnecessary energy waste, which runs counter to the original intention of energy conservation and emission reduction.

[0005] Currently, the photovoltaic cleaning robots on the market generally use a rotary brush at a fixed position to clean the surface of solar panels. For example, in the Chinese utility model patent with the publication number CN219899274U, a design of a solar panel cleaning brush is shown. Through the coordinated work of components such as a motor, a driving gear, a driven gear, a rotating rod, and a placement plate, the simultaneous cleaning of the dust on the outer surfaces of multiple solar panels is achieved. Through the delicate cooperation of components such as a movable groove, a stress spring, a movable block, a connecting plate, a limiting slide rail, and a pulley, the close fit between the rotary brush and the surface of the solar panel is ensured, improving the cleaning effect. However, this fixed cleaning method has significant defects, that is, it ignores the problems of equipment wear and energy waste caused by excessive cleaning force. In practical applications, the pollution degrees of different solar panels vary greatly, so the fixed cleaning force often cannot meet the actual needs. In summary, there is a need to invent a cleaning device with adjustable cleaning force. Summary of the Utility Model

[0006] In view of the above technical problem that the existing cleaning equipment cannot adopt different cleaning intensities according to the pollution degree, a cleaning device with adjustable intensity applied to solar panels is provided. By controlling the degree of fitting between the rotary brush and the solar panel, the cleaning robot of the present utility model can adjust the cleaning intensity, thereby improving the cleaning performance of the present utility model. This efficient cleaning method can improve the cleaning efficiency and avoid the decline in power generation efficiency and potential safety hazards caused by incomplete cleaning.

As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

The cleaning force adjustment device is respectively connected to the rotary brush 3 and the scraper 4. The water tank is connected to the nozzle, and a cleaning liquid or water is arranged in the water tank.

[0037] The cleaning intensity adjustment device includes a horizontal bevel gear 5 arranged in the middle of the vehicle body 1. The horizontal bevel gear 5 is horizontally placed and connected to the driving end of a motor 6. The motor 6 is arranged below the horizontal bevel gear 5. The upper left and right ends of the horizontal bevel gear 5 are respectively engaged with a first bevel gear 7 and a second bevel gear 8. The first bevel gear 7 and the second bevel gear 8 are vertically arranged, and the conical surfaces of the first bevel gear 7 and the second bevel gear 8 are arranged opposite to each other. The plane of the first bevel gear 7 is connected to one end of a first rigid coupling 9, and the plane of the second bevel gear 8 is connected to one end of a second rigid coupling 10. The other end of the first rigid coupling 9 is connected to a first threaded rod 11, and the other end of the second rigid coupling 10 is connected to a second threaded rod 12. A first universal joint 23 is arranged between the first rigid coupling 9 and the first threaded rod 11, and a second universal joint 24 is arranged between the second rigid coupling 10 and the second threaded rod 12. The first rigid coupling 9 and the first universal joint 23 are connected through a first connecting block 25, and the second rigid coupling 10 and the second universal joint 24 are connected through a second connecting block 26. The first connecting block 25 and the second connecting block 26 are fixed on the bottom plate 27 of the vehicle body 1 through a motor support frame 22. The other end of the first threaded rod 11 is connected to a first rotatable base 13, and the other end of the second threaded rod 12 is connected to a second rotatable base 14. The two ends of the first rotatable base 13 are symmetrically provided with first special-shaped force transmission beams 15 and are connected to the tops of the first special-shaped force transmission beams 15. The two ends of the second rotatable base 14 are symmetrically provided with second special-shaped force transmission beams 16 and are connected to the tops of the second special-shaped force transmission beams 16. The bottom of the first special-shaped force transmission beam 15 is connected to a first transmission shaft 17, and the bottom of the second special-shaped force transmission beam 16 is connected to a second transmission shaft 18;

[0038] Both ends of the first transmission shaft 17 are respectively connected to a first vertical connecting rod 19. One end of the first vertical connecting rod 19 is connected to the vehicle body 1, and the other end of the first connecting rod is connected to a transverse connecting rod 20. The lower part of the transverse connecting rod 20 is connected to a rotary brush 3;

[0039] Both ends of the second transmission shaft 18 are respectively connected to a second vertical connecting rod 21. One end of the second vertical connecting rod 21 is connected to the vehicle body 1, and the other end of the second connecting rod is connected to a scraper 4. The motor 6 is arranged on the motor support frame 22, and the motor support frame 22 is arranged on the bottom plate 27 of the vehicle body 1.

[0040] When cleaning the dust accumulated on the photovoltaic module power generation panel, the nozzle sprays water or cleaning liquid from the water tank onto the surface of the solar panel. The external operator sends a corresponding duration signal to the motor 6 according to the cleaning intensity desired. The motor 6 receives the duration signal and controls the rotation time of the motor 6 according to the duration signal. The stronger the cleaning intensity desired by the external operator, the longer the power-on time and the rotation time of the motor 6, so as to further make the crawler 2 and the rotary brush 3 fit better with the solar panel. The motor 6 drives the horizontal bevel gear 5 to rotate, and then can drive the threaded rod to rotate through a rigid coupling, so that the rotatable base starts to rotate. The rotatable base drives the special-shaped force transmission beam to rotate, and the special-shaped force transmission beam drives the transmission shaft to be stressed, so as to achieve the effect of changing the fitting degree between the rotary brush 3 and the scraper 4 and the solar panel. The rotary brush 3 contacts the cleaning liquid or water to clean the solar panel, and the dirty water after cleaning is scraped off by the scraper.

[0041] According to the above working process, it can be seen that when the rotation speed of the motor 6 is increased, the rotation angle of the transmission shaft becomes larger, and at the same time, the rotatable base in the assembly part is forced to press down, and through the transmission device, the rotary brush 2 and the scraper 3 are pressed tightly against the solar panel, so that they can work powerfully, avoiding the decline of the power generation efficiency of the power generation panel and potential safety hazards caused by incomplete cleaning; when the rotation speed of the motor 6 is decreased, the rotation angle of the transmission shaft becomes smaller, and at the same time, the degree of the rotatable base in the assembly part being forced to press down is reduced, and through the transmission device, the fitting degree between the rotary brush and the solar panel is reduced, so as to improve the cleaning efficiency and reduce energy consumption.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
