摘要： Disclosed are a main beam and a use thereof and a photovoltaic tracking bracket, wherein the main beam includes a flat plate and an elliptical curved plate, each of both ends of the flat plate are respectively fixedly connected to a corresponding end of the elliptical curved plate to form a ring shape, and a plane where the flat plate is located is perpendicular to a long axis of an ellipse where the elliptical curved plate is located. Also provided is the use of the main beam in the photovoltaic tracking bracket. The photovoltaic tracking bracket includes the main beam; a stand column; and a bearing seat comprising a bearing ring, a Z-shaped support plate and a bottom plate connected sequentially from top to bottom, wherein the Z-shaped support plate has a Z-shaped cross section, the main beam is installed inside the bearing ring, the flat plate of the main beam faces a photovoltaic assembly, and the bottom plate is connected to the stand column. Under the premise of ensuring the same thickness, the main beam of the present invention improves the resistance moment of the lateral cross section and saves costs, and when applied to the photovoltaic tracking bracket, the main beam can slow down the hot spot effect of the double-sided photovoltaic assembly and prolong the service life of the same.
