[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. With the continuous improvement of photovoltaic power generation technology, solar photovoltaic power generation devices are increasingly used in people's production and life. Compared with conventional energy, the use of solar power generation does not pollute the environment, does not require the transportation of raw materials, can be developed locally, can solve the electricity demand in remote areas, and can alleviate the power shortage in cities. However, due to the rotation of the earth and other reasons, it is difficult to ensure that the photovoltaic panels installed with a fixed structure will directly shine on the photovoltaic panel surface for a long time. When the sunlight shines obliquely on the photovoltaic panel, the energy density of the solar energy is low, which affects the solar energy conversion efficiency of the photovoltaic panel.

[0003] In the prior art, the utility model with application number 202320951597.2 discloses an adjustable bracket for photovoltaic power generation. Although the angle of the photovoltaic panel can be adjusted by rotating the second bevel gear through the rotation and engagement of the first bevel gear, and cooperating with the rotation of the guide threaded slide rod, the angle direction adjustment of the photovoltaic panel is relatively simple, and it is difficult to adjust in real time following the changes in the sunlight. Therefore, the present application provides a photovoltaic power generation device that can actively track the sun to meet the needs. Utility Model Content
