[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels (modules), controllers and inverters. The main components are composed of electronic components. Solar cells are connected in series and then packaged and protected to form large-area solar cell modules. Combined with components such as power controllers, photovoltaic power generation devices are formed.

[0003] In order to make the sunlight directly hit the photovoltaic array, thereby increasing the amount of solar radiation received by the photovoltaic array and improving the overall power generation of the solar photovoltaic power generation system, the solar photovoltaic array will be rotated to track the movement of the sun in real time. In this process, a photovoltaic bearing seat will be used to support and rotate the main shaft of the photovoltaic array.

[0004] As a key component supporting and rotating the main shaft of the photovoltaic array, the installation accuracy of the photovoltaic bearing seat directly affects the stability and power generation efficiency of the entire system. During the installation process of traditional bearing seats, especially the welding between the clamp on the outside of the bearing body and the bearing seat bracket, the welding quality is often inconsistent due to positioning difficulties, affecting the firmness of the overall structure. Therefore, a photovoltaic bearing seat that is easy to weld and position is proposed. Utility Model Content
