Description

Flexible photovoltaic support connecting device TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic devices, in particular to a flexible photovoltaic support connecting device. BACKGROUND

[0002] The flexible photovoltaic support is a structural system for installing photovoltaic modules, which has higher flexibility and adaptability compared with the traditional rigid support. The flexible photovoltaic support is widely used in harsh environments such as beaches, farming and animal husbandry, sewage treatment plants, fish ponds, complex mountainous areas and barren slopes, and has the characteristics of large span capacity and flexibility.

[0003] The load-bearing cable of the flexible photovoltaic support needs to be prestressed and tensioned to form a certain stiffness to lay the photovoltaic modules. The cable force of the tensioned steel strand will generate a large horizontal load on the support. The photovoltaic modules are connected to the load-bearing cable through a lock buckle. However, the size of the lock buckle is difficult to adapt to steel strands of different diameters, making it difficult to install on the steel strand. In addition, due to vibration or wind action, the connected photovoltaic modules may be offset. In practical use, the connecting lock buckle is generally fixed in a single point, which may cause uneven stress. When connecting the photovoltaic modules, bolts are usually used for connection, which may easily cause the phenomenon of falling off due to vibration, and the connection is unstable.
