[0002] Solar energy is a clean energy that conforms to the new concept of sustainable development. In recent years, the solar photovoltaic power generation industry has developed rapidly. Solar photovoltaic power generation technology is a technology that converts solar energy into electrical energy through photovoltaic panels. Photovoltaic panels usually use the photovoltaic effect principle of semiconductor devices for photoelectric conversion. Photovoltaic power generation systems are widely used, and currently there are mainly large-scale centralized grid-connected power generation systems and rooftop photovoltaic power generation systems.

[0003] During the installation process, a relatively simple bracket structure is generally used to fix the solar photovoltaic panel so that it can be set up on the roof or on the ground. As a result, the setting angle of the photovoltaic panel is fixed, so that it cannot play an efficient energy collection effect. Summary of the invention

Thus, when the sun is at its highest at noon, the two photovoltaic panels can be 180°, fully corresponding to the illumination route.

At the same time, multiple rollers are provided to support the bottom plate at the top of the bottom frame, avoiding the lifting and adjusting mechanism from pressing down and affecting the contact between the second roller and the hollow circular ring support frame, thereby ensuring the normal operation of the dust removal mechanism.
