DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Example

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention provides a technical solution for a self-cleaning photovoltaic power generation device: a solar panel 11 is installed on the upper part of the photovoltaic module housing 1, and the solar panel 11 is used to receive sunlight and convert it into electrical energy. A cleaning mechanism is arranged above the solar panel 11, and the cleaning mechanism includes a housing 3, a bottom plate 31 is installed in the housing 3, and a motor 32 is fixed on the bottom plate 31. The output end of the motor 32 is connected to a main sprocket 33, and rotating sprockets 36 are respectively arranged on both sides of the main sprocket 33, and the rotating sprocket 36 is connected to the main sprocket 33 through a chain 37. A connecting column 39 is installed in the shaft hole of the rotating sprocket 36, and a cleaning brush disc 38 is fixed at the bottom of the connecting column 39, and the cleaning brush disc 38 is used to remove pollutants on the surface of the solar panel 11. A moving mechanism is arranged on the photovoltaic module housing 1, and the moving mechanism includes two groups of mounting frames 21, and two groups of parallel guide rods 22 are installed on the mounting frames 21, and reinforcement blocks 23 are connected to both ends of the guide rods 22. A translation plate 24 is arranged between the guide rods 22, the housing 3 and the bottom plate 31 are mounted on the translation plate 24, a rotation hole 241 is penetrated on the translation plate 24, and a connecting column 39 penetrates the rotation hole 241 and is rotationally connected thereto. A moving frame 25 is installed at the edge of the bottom surface of the translation plate 24, and a plurality of groups of moving wheels 26 are arranged on the moving frame 25, and the moving wheels 26 are rollingly matched with the guide rods 22, and one group of the moving wheels 26 is driven by a travel drive motor 27. A tensioning sprocket 1 34 and a tensioning sprocket 2 35 are arranged on the inner side of the chain 37, and the tensioning sprocket 1 34 and the tensioning sprocket 2 35 are connected to the bottom plate 31, and are used to keep the tension state of the chain 37.

[0026] Through the above structure, the cleaning mechanism can perform translational and rotational movements on the surface of the solar panel 11, thereby achieving comprehensive cleaning of the surface of the solar panel 11. The setting of the moving mechanism enables the cleaning mechanism to cover the entire area of ​​the solar panel 11, ensuring cleaning without dead corners. The use of the travel drive motor 27 allows the cleaning mechanism to automatically move on the surface of the solar panel 11, greatly reducing the demand and cost of manual cleaning. In addition, the rotational movement of the cleaning brush disc 38 can effectively remove pollutants such as dust and bird droppings attached to the surface of the solar panel 11, ensuring the cleanliness and power generation efficiency of the solar panel 11.

[0027] In this embodiment, when cleaning is required, the travel drive motor 27 is started, and the moving wheel 26 is driven to roll along the guide rod 22, so that the cleaning mechanism moves in translation along the surface of the solar panel 11. At the same time, the motor 32 is started, and the connecting column 39 is driven to rotate through the main sprocket 33 and the rotating sprocket 36, thereby rotating the cleaning brush disc 38. While the cleaning brush disc 38 is rotating, the translation plate 24 moves, so that the surface of the solar panel 11 can be effectively cleaned.

[0028] Since the tensioning sprocket 1 34 and the tensioning sprocket 2 35 are arranged inside the chain 37, the chain 37 maintains an appropriate tension, ensuring that the chain will not loosen or fall off during the movement of the cleaning mechanism, thereby ensuring the stable operation of the cleaning mechanism.

[0029] The self-cleaning photovoltaic power generation device of the present invention not only improves power generation efficiency and reduces maintenance costs, but also takes environmental adaptability into consideration in its design, so that the device can operate stably under various climatic conditions. For example, in dusty areas, the frequency of the cleaning mechanism can be set higher to cope with the rapid accumulation of dust. In rainy areas, the frequency of use of the water spray system can be reduced to avoid unnecessary waste of water resources during the cleaning process.

[0030] In summary, the self-cleaning photovoltaic power generation device of the present invention not only solves the cleaning and maintenance problems of traditional photovoltaic power generation devices through its unique design, but also improves the overall performance and economic benefits of the device. Its innovative self-cleaning function enables the photovoltaic power generation device to maintain efficient and stable power generation capacity for a long time, providing new possibilities for the widespread application of solar energy.
