Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology.
[0003] With the continuous development of renewable energy technology, bifacial photovoltaic modules have gradually become a research hotspot and application focus in the photovoltaic industry because they can receive solar energy from both sides at the same time, thereby significantly improving power generation efficiency. However, most traditional photovoltaic module mounting brackets are fixed and cannot adjust the angle of the photovoltaic module according to the position of the sun, resulting in the photovoltaic module being unable to fully receive solar energy, thereby reducing power generation efficiency. Therefore, a mounting bracket for bifacial photovoltaic modules is proposed. Utility Model Content

[0030] Working principle: When the double-sided photovoltaic panel 3 is installed, firstly, multiple mounting seats 1 are installed on the ground, and then the reducer 7 is installed on the top of the middle mounting seat 1, and the second motor 9 is installed together with the reducer 7, and then the rotating frame 8 is connected to the output shaft end of the reducer 7, and the support frame 6 is connected to the double-sided photovoltaic panel 3, and the support frame 6 is connected to the rotating frame 8. The controller is used to control the rotation of the output shaft of the second motor 9 to drive the input shaft of the reducer 7 to rotate, and the rotating frame 8 is driven to rotate by the output shaft of the reducer 7, so that the angle of the double-sided photovoltaic panel 3 changes, thereby increasing the power generation efficiency of the double-sided photovoltaic panel 3. Adjusting the angle of the double-sided photovoltaic panel 3 can ensure that the double-sided photovoltaic panel 3 can receive sunlight to the greatest extent during most of the day, which can not only improve the power generation efficiency of the front side of the double-sided photovoltaic panel 3, but also effectively utilize the light on the back side, thereby improving the power generation efficiency as a whole;
[0031] The worker regularly fills the liquid storage tank 56 with cleaning liquid through the filling pipe 4, and then tightens the rubber plug at one end of the filling pipe 4. At night when there is no sunlight, the controller controls the water pump 512 and the first motor 513 to start working. At this time, the water pump 512 extracts the cleaning liquid in the liquid storage tank 56, and the cleaning liquid is transported by the water pipe so that the cleaning liquid is sprayed onto the surface of the double-sided photovoltaic panel 3 through multiple water spray holes 58. When the cleaning liquid is sprayed onto the surface of the double-sided photovoltaic panel 3, the output shafts of the two first motors 513 respectively drive the first screw rod 57 and the second screw rod 511 to rotate. When the first screw rod 57 rotates, the first brush plate 54 moves up and down along the first slide column 55. The bristles on one side of the bottom of the first brush plate 54 brush off the dirt on the surface of the double-sided photovoltaic panel 3, and at the same time, when the second screw rod 511 rotates, the two second brush plates 59 move up and down along the second sliding column 510. When the first brush plate 54 and the second brush plate 59 clean the dirt on the surface of the double-sided photovoltaic panel 3, the cleaning liquid is preferentially sprayed onto the surface of the double-sided photovoltaic panel 3. After the surface of the double-sided photovoltaic panel 3 is cleaned, the first brush plate 54 and the second brush plate 59 on the upper side are located on the inner side of the limiting groove 52, and the second brush plate 59 on the lower side moves to the side of the rotating frame 8, so as to minimize the influence of the second brush plate 59 on the power generation efficiency of the double-sided photovoltaic panel 3.
[0032] The cleaning liquid in the liquid storage tank 56 is extracted by the water pump 512 and evenly sprayed onto the surface of the double-sided photovoltaic panel 3 through the water spray hole 58. The up and down movement of the first brush plate 54 and the second brush plate 59 can effectively remove the dirt on the surface of the double-sided photovoltaic panel 3, ensuring that the double-sided photovoltaic panel 3 can efficiently receive sunlight to generate electricity on the next day. During the cleaning process, the cleaning liquid is preferentially sprayed onto the surface of the double-sided photovoltaic panel 3, which can soften and decompose the dirt on the surface. Regular cleaning can maintain the cleanliness of the surface of the double-sided photovoltaic panel 3 and reduce the light loss caused by dirt blocking, thereby improving the power generation efficiency of the photovoltaic panel.
