Sunflower-shaped automatic open-close type solar photovoltaic panel

Abstract

The invention relates to a sunflower-shaped automatic open-close type solar photovoltaic panel. The solar photovoltaic panel comprises a controller, a central shaft, multiple circular bins orderly installed on the central shaft in a rotatable way, an unfolding motor fixedly installed at the upper end of the central shaft and used for driving the circular bins to rotate, and an installation plate fixedly installed at the lower end of the central shaft and used for connecting with the bracket; the unfolding motor is connected with a controller circuit; each circular bin is fixedly connected with a photovoltaic panel; the number of the circuit bin is eight, an internal tooth track is arranged at the front side of each circular bin, and a stopper is arranged at the end part of the internal tooth track; an output shaft of the unfolding motor is connected with a gear plate, and the gear plate is engaged with the inner tooth track of the first circular bin. Compared with the prior art, the unfolded photovoltaic panel is arranged in a sunflower way, and the opening process is a sector type opening; the photovoltaic panel can be folded in advance according to a weather forecast condition in the face of extreme weather, and the damage probability of the photovoltaic panel caused by severe weather is greatly lowered.

Description

technical field [0001] The invention relates to a solar photovoltaic panel, in particular to a sunflower-shaped automatic opening and closing solar photovoltaic panel. Background technique [0002] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. At present, in order to facilitate the transfer of photovoltaic panels and cope with extreme weather such as strong winds, heavy snow, hail, or sandstorms, some solar photovoltaic panels are set to be foldable. When using such photovoltaic panels, unfold them and expose them to places with better lighting. Photovoltaic panels ensure sufficient lighting area. When encountering extreme weather, put it away, so as to avoid damage to photovoltaic panels caused by bad weather. [0003] However, the existing photovoltaic panels have the following technical defects i...

Problems solved by technology

[0003] However, the existing photovoltaic panels have the following technical defects in the process of use: ① after the photovoltaic panels are unfolded, they are mostly arranged in a rectangular or square large area. The panel is damaged; ②The rectangular or square arrangement makes the driving structure for unfolding and retracting the photovoltaic panel complex, which increases the processing and manufacturing costs; ③Since the solar photovoltaic panel is exposed to the outdoor unshaded environment for a long time, , the surface of the photovoltaic
