[0002] Solar power generation is a beneficial supplement to traditional power generation. In view of its importance to environmental protection and economic development, all developed countries have made every effort to promote solar power generation, and small and medium-scale solar power generation has formed an industry. There are two ways of solar power generation: photovoltaic power generation and solar thermal power generation. Among them, photovoltaic power generation has the outstanding advantages of simple maintenance and variable power. It is widely used as a medium and small grid-connected power source. After searching, a Chinese patent with the authorization announcement number of CN210380723U discloses a distributed photovoltaic grid-connected power generation device that is easy to install, including a photovoltaic box and several photovoltaic panels installed inside it. The back of the photovoltaic box is connected with a pillar, and a circular ring platform is symmetrically welded on one side of the bottom end of the pillar. A pull rod is hinged between the two circular ring platforms. The outer end face of the pull rod is provided with a square inner cavity, and a stretch rod is inserted inside the inner cavity. The top of the stretch rod can also be connected with two protrusions. The utility model hinges a pillar on the back of the photovoltaic box and hinges a pulling rod on the bottom end of the pillar, thereby forming a triangle with the photovoltaic box, stably supporting the photovoltaic box, and making the installation convenient and stable; the inclination angle of the photovoltaic box is dynamically adjusted by adjusting the extended length of the stretching rod, so that light is fully absorbed.
