[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments can be combined with each other. The described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] like Figures 1 to 3 As shown, the utility model provides a photovoltaic module dust cleaner, including a support plate 1, wherein a top plate 2 and a bottom plate 3 are respectively arranged at opposite ends of the support plate 1, and the top plate 2, the bottom plate 3 and the support plate 1 are integrally formed and arranged in a U-shaped structure; a water absorption structure is arranged on the top plate 2, and the water absorption structure is used to discharge dust and accumulated water on the photovoltaic module 10; a plurality of support points 4 are arranged on one side of the support plate 1 close to the top plate 2, and the support points 4 are used to support the photovoltaic module 10, and a drainage hole 5 is opened on the support plate 1.

[0024] A further optimized solution is that the water absorption structure includes a clamping plate 6, which is fixedly arranged at one end of the top plate 2 away from the support plate 1, and a water absorption port 7 is opened on the clamping plate 6, and the water absorption port 7 is arranged on a side of the clamping plate 6 that is attached to the photovoltaic component 10.

[0025] According to a further optimization scheme, a plurality of water leakage holes 8 are provided on the top plate 2 .

[0026] According to a further optimized solution, a plurality of drainage grooves 9 are provided on the top plate 2 .

[0027] According to a further optimized solution, the drainage hole 5 is a V-shaped structure, and the large diameter end of the drainage hole 5 is arranged close to the top plate 2.

[0028] According to a further optimized solution, the bottom plate 3 is an inverted V-shaped structure, and the middle portion of the bottom plate 3 is in contact with the frame 11 of the photovoltaic module 10 .

[0029] According to a further optimized solution, the number of the supporting points 4 is set to four, and the four supporting points 4 are arranged in a rectangular array.

[0030] According to a further optimization scheme, the width of the top plate 2 is adapted to the width of the frame 11 of the photovoltaic module 10 .

[0031] The photovoltaic module dust cleaner provided by the utility model, when in use, first, install the dust cleaner on the photovoltaic module 10 that needs maintenance, and the dust cleaner is set on the dust accumulation belt of the photovoltaic module 10, and the four support points 4 ensure the stability of the dust cleaner, so that it can withstand the influence of bad weather such as wind and rain, and effectively resist loosening or falling off caused by vibration or impact. When it rains, rainwater will flow down the photovoltaic module 10, and through the leakage hole 8 on the top plate 2, the rainwater can be directly discharged from the leakage hole 8. At the same time, the rainwater will form a siphon effect under the action of the water suction port 7 and the drainage groove 9. The power of rainwater is used to push the dust on the surface of the photovoltaic module 10 to the drainage hole 5, and the dust and accumulated water on the photovoltaic module 10 will eventually be discharged through the drainage hole 5, realizing the self-cleaning of the photovoltaic module 10. The specially designed large-size drainage hole 5 allows the water to flow unimpeded, and the maximum drainage volume can reach 900 grams / minute. Even in extreme weather conditions, it can maintain excellent drainage performance. Since there are no protruding grooves inside the cleaner except the supporting point 4, the internal structure is simple and smooth, and there are no unnecessary protrusions, so dust cannot accumulate here, which not only reduces the retention space of dust, but also slows down the erosion of moisture on the cleaner, greatly enhancing durability. This not only ensures the cleaning effect, but also extends the service life of the system.

[0032] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
