The distributed photovoltaic power generation can give full play to solar energy resources according to local conditions, has higher economic efficiency and investment value, and is developed vigorously in China at present. However, under the condition that high-quality land resources are increasingly tense, the traditional photovoltaic support is limited in construction and development due to the reasons of large occupied area, high requirement on field flatness, incapability of secondary utilization of land and the like. And the flexible photovoltaic support only occupies the land area by the supporting structure, has low requirement on the field area, and can be widely applied to various complex terrains. Meanwhile, the flexible photovoltaic support is relatively low in manufacturing cost, and space resources and solar resources can be fully utilized, so that the flexible photovoltaic support has good economic benefits.

The solar photovoltaic flexible support is formed by mounting photovoltaic panels on steel cables in rows to form a large-span array system. Under the action of wind load, the photovoltaic modules swing along with the wind load, in order to enable the photovoltaic modules of all the spans to be stressed cooperatively and reduce the influence caused by large-amplitude swing, cross brace rod devices are required to be arranged among the spans, and therefore the flexible support array forms an integral system.

The prior art cross brace devices are typically in the form of two round steel tubes with no connections. The device can form a system by the flexible support array, but cannot restrict the deformation of the flexible support array, and has weak capability of eliminating the deformation under wind load.

In addition, the cross brace rod device in the prior art also has two channel steel connected through screws, and the device can restrain deformation under wind load, but restrain too strong, and the cooperation ability between systems is weak, and is unfavorable for material durability.
