Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a single-axis full-drive tracking photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a green energy that utilizes solar energy resources. It is a new industry that the country is currently vigorously promoting, and it is also a clean energy technology with broad prospects and potential. It converts light energy into electrical energy through solar panels to power our lives.

[0003] 1. Fixed-angle photovoltaic bracket adopts a single-column or double-column structure. According to the local solar operation law, the optimal incident angle between the sun and the photovoltaic module is determined. It has a simple structure, stable performance and low cost. However, the utilization rate of solar light is low, the power generation is average, and other protective measures cannot be taken for the photovoltaic modules in extreme weather (strong wind, heavy snow).

[0004] 2. The adjustable photovoltaic bracket adopts a single-column single-axis structure and a single-column dual-axis structure. The single-column single-axis structure is divided into manual and automatic forms; the single-column dual-axis structure is a fully automatic light-chasing system; the manual form of the single-column single-axis structure manually adjusts the component angle according to different seasons through the bracket adjustment mechanism; its structure is simple and can increase some light radiation; but the labor is huge (each centralized photovoltaic power plant has thousands of photovoltaic arrays), the labor cost is high, the increased power generation is limited, and the cost performance is not high; the automatic form of the single-column single-axis structure currently has manufacturers using wire ropes, fan gears and hydraulic telescopic tubes, etc. Driven by large electric motors, the angle can be automatically adjusted according to the sunshine or season. It can significantly increase the amount of light radiation and significantly improve the power generation. In extreme weather (strong wind, heavy snow), the photovoltaic modules can take automatic protection measures. However, the bracket system is huge, the failure rate is high, the accident has a large impact, and it is not convenient for debugging and maintenance. The single-column dual-axis automatic tracking structure is the bracket structure with the highest power generation efficiency. It uses two small motors to automatically track the light according to the sunshine, thereby adjusting the angle of the module. However, due to the physical properties of the bracket steel, only a few photovoltaic modules can be installed in each string of the array. The high cost and high failure rate are not conducive to large-scale promotion.

[0005] To this end, we propose a single-axis full-drive tracking photovoltaic bracket. Utility Model Content
