Technical Problem

[0003]现有的翼展式光伏储能装置通常采用将光伏板相互转接为一体的结构设计，在实际使用过程中，通过两个伸缩支架的伸展作用将光伏板向外展开，从而实现装置的展开功能，然而，这种将光伏板连接为一体的设计方式在起风环境下存在明显缺陷，由于光伏板整体受风面积过大，使得装置在风力作用下容易产生较大的振动，尤其是在阵风或强风环境中，这种振动会显著降低光伏板的结构稳定性，此外，集中受风还会导致光伏板承受更大的风压载荷，增加装置整体的机械应力，从而引发疲劳损伤或安全隐患

Benefits of technology

[0015]Compared with the prior art, the present invention has the following advantages: 1. The present invention groups photovoltaic panels and distributes them in a modular manner, with gaps between each group of photovoltaic panels to optimize the flow path of external airflow, thereby effectively reducing the force of airflow on photovoltaic panels and improving the structural stability of the device in windy environments. In addition, each group of photovoltaic panels adopts a counter-folding method, which allows impurities on them to fall off by gravity during recycling, reducing the frequency of maintenance of photovoltaic panels by staff.

Abstract

The application discloses a stable span type photovoltaic energy storage device and belongs to the technical field of solar energy industry. The device comprises an energy storage base, two symmetrical expansion supports arranged on the energy storage base, a driving module arranged on the energy storage base, a plurality of rotating sleeves rotatably connected to the expansion supports, and two symmetrical photovoltaic panels rotatably connected to the rotating sleeves. In the expanded state of the expansion supports, the distance between two adjacent rotating sleeves is greater than the sum of the widths of the two photovoltaic panels. A tensioning assembly is arranged on the energy storage base and used for driving all the photovoltaic panels to deflect along the adjacent rotating sleeves. The photovoltaic panels are grouped and modularly distributed, and gaps are arranged between each group of photovoltaic panels, so that the flow path of external wind flow is optimized, the force of wind flow on the photovoltaic panels is effectively reduced, and the structural stability of the device in a windy environment is improved.
