[0023] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0024] like Figures 1-4As shown, the utility model provides a photovoltaic module cleaning device, including: a cleaning device body 100, where the cleaning device body 100 includes a roller brush frame 1, and the roller brush frame 1 is movably mounted on a track rod 2 of a photovoltaic frame (not shown), and a photovoltaic module 200 is mounted on the photovoltaic frame, where the track rod 2 is located above the photovoltaic module 200, thereby also making the roller brush frame 1 located above the photovoltaic module 200. Furthermore, a plurality of roller brush members 3 are mounted on the roller brush frame 1, and a water spray mechanism 4 is also mounted on the roller brush frame 1, so when the cleaning device body 100 is used, the roller brush frame 1 moves along the track rod 2, and then the water spray mechanism 4 on the roller brush frame 1 performs high-speed water spray cleaning on the photovoltaic module 200, thereby removing part of the dust on the surface of the module and softening highly adhesive pollutants, thereby facilitating the subsequent cleaning of the roller brush member 3. The cleaning device body 100 of the utility model has a simple structure, high cleaning efficiency, and low cost, and can be used for cleaning components of large photovoltaic power stations, thereby increasing the power generation of the components.

[0025] Furthermore, the photovoltaic assembly 200 includes multiple photovoltaic panels 201, and adjacent photovoltaic panels 201 are connected by fixing blocks 202. Therefore, the photovoltaic assembly 200 can be composed of multiple photovoltaic panels 201, thereby enabling the cleaning device body 100 to be used for cleaning components of large photovoltaic power stations, thereby increasing the power generation of the components.

[0026] Exemplary roller brush holder

[0027] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned roller brush rack 1, and the roller brush rack 1 of this structure includes a Y-shaped seat 11 and two rack rods 12. Specifically, one end of the Y-shaped seat 11 is movably mounted on the track rod 2, and the two rack rods 12 are respectively mounted on the other two ends of the Y-shaped seat 11, so that the two rack rods 12 are also located above the photovoltaic component 200. A plurality of roller brush members 3 are mounted on the rack rods 12, so that when the roller brush member 3 is started, the photovoltaic component 200 is cleaned, and the Y-shaped seat 11 moves on the track rod 2, and then the roller brush member 3 can also move, which facilitates the cleaning of the entire photovoltaic component 200, so that the cleaning device main body 100 is used to clean large-scale photovoltaic power station components, thereby improving the power generation of the components.

[0028] Furthermore, in some embodiments of the present invention, a power mechanism 13 is installed on the Y-shaped seat 11, and the power mechanism 13 drives the Y-shaped seat 11 to reciprocate on the track rod 2; specifically, the power mechanism 13 of this structure includes an outer shell 14, a built-in motor 15, and a power wheel 16. The outer shell 14 is installed on one end of the Y-shaped seat 11, the built-in motor 15 is installed in the outer shell 14, and the power wheel 16 is installed on the built-in motor 15 through a reduction member 17. When the built-in motor 15 is started, the built-in motor 15 drives the reduction member 17 to drive the power wheel 16, so that the power wheel 16 moves back and forth on the track rod 2, thereby driving the entire roller brush frame 1 to move above the photovoltaic component 200, and then the roller brush member 3 can perform roller brush cleaning on the photovoltaic component 200, greatly improving the cleaning efficiency.

[0029] It is understandable that the track rod 2 may have a plurality of first protruding teeth (not shown), and the power wheel 16 may have a plurality of second protruding teeth (not shown), and the second protruding teeth engage with the first protruding teeth, so that the power wheel 16 can move on the track rod 2.

[0030] In addition, two first limit sensors (not shown) can be installed on the track rod 2, and a corresponding second limit sensor (not shown) can be installed on the housing 14. Therefore, when the power mechanism 13 moves on the track rod 2, the detection between the first limit sensor and the second limit sensor can be used to avoid excessive movement of the power mechanism 13.

[0031] Furthermore, the above-mentioned roller brush component 3 includes a roller brush motor 31 and a roller brush plate 32, wherein the roller brush motor 31 is installed on the frame rod 12, and the roller brush plate 32 is installed on the motor shaft of the roller brush motor 31. There are roller brush bristles 33 on the roller brush plate 32, so after the roller brush motor 31 is started, it can drive the roller brush plate 32 to rotate, and then the roller brush bristles 33 on the roller brush plate 32 perform roller brush cleaning on the photovoltaic component 200, thereby greatly improving the cleaning efficiency.

[0032] Exemplary water spray mechanism

[0033] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned water spraying mechanism, in which two water spraying mechanisms 4 are provided and are respectively connected to the rack 12, and the water spraying mechanism 4 is located on one side of the rack 12. Specifically, the water spraying mechanism 4 includes a water spraying pipe 41 and multiple water spraying heads 42. Here, the water spraying pipe 41 is connected to the rack 12 through two support rods 411, and multiple water spraying heads 42 are installed on the water spraying pipe 41, and the two water spraying pipes 41 are connected to the water spraying hose 5. Therefore, after the water spraying hose 5 supplies water to the two water spraying pipes 41, water can be sprayed out from the water spraying head 42 at a high speed, thereby realizing water spraying and cleaning of the photovoltaic component 200. Here, the two water spraying mechanisms 4, one is to remove part of the dust on the surface of the photovoltaic component 200 through high-speed, high-pressure water flow; second, the water flow can soften highly adhesive pollutants, which is convenient for the subsequent rotation and cleaning of the roller brush 3; third, the infiltration effect of the water flow can avoid stirring up dust during the rotation of the roller brush 3, thereby preventing secondary pollution.

[0034] like Figure 5 As shown, further, there are two track rods 2, which are respectively located on the upper and lower sides of the photovoltaic component 200, and another Y-shaped seat 11 is installed on the lower track rod 2, and the two rack rods 12 are connected to the other Y-shaped seat 11, so the stability of the roller brush rack 1 is increased through the setting of the above structure.
