The ground pile 10, the first steel wire rope 13, the second steel wire rope 9 and the limiting piece jointly constitute a vibration reduction assembly 4.

[0026] The wind-resistant ground anchor structure currently used by the steel wire rope is straightened and connected to the ground pile 10. When the overall flexible photovoltaic support is subjected to wind force and moves upward, only the rigidity of the ground pile 10 can reduce the amplitude. When the wind force is too large, the steel wire rope is easily broken or the ground pile 10 is pulled out, causing structural failure.

[0027] Compared with the wind-resistant ground anchor structure in the prior art which is always in a tensioned state, the spring 12 with damping and buffering effect is fixedly connected to the bottom of the triangular support 6 in the present application, which reduces the instantaneous stress on the first steel wire rope 13 and the second steel wire rope 9, avoids the breakage of the first steel wire rope 13 and the second steel wire rope 9 due to instantaneous impact, and affects the safety of the overall flexible photovoltaic support. In addition, the resistance is increased by the counterweight 8, which provides multiple safeguards, effectively reduces the vibration amplitude of the flexible photovoltaic support, and improves the structural safety.

[0028] When the overall flexible photovoltaic support is subjected to wind force and moves upward, the spring 12 is first stretched, and the damping of the spring 12 is used for vibration reduction. While the spring 12 moves, the counterweight 8 is driven upward by the first steel wire rope 13, and the vibration and gravity of the counterweight 8 further consume wind vibration energy. Finally, the second steel wire rope 9 is straightened, the resistance to pull-out is provided by the ground pile 10, multiple safeguards are provided, the vibration amplitude of the flexible photovoltaic support is effectively reduced, and the structural safety is improved.

[0029] In some optional embodiments, the limiting piece is a rectangular frame 11, the top of the spring 12 penetrates the rectangular frame 11 to fixedly clamp the triangular support 6, and the top of the first steel wire rope 13 penetrates the rectangular frame 11 to connect the bottom of the spring 12.

[0030] Further, the height of the rectangular frame 11 is less than the limit stretching length of the spring 12.

[0032] Further, the total length of the limiting section 14 is less than the limit length of the spring 12.

[0033] In some optional embodiments, a connecting cable 5 is fixedly connected between the triangular supports 6, and the connecting cable 5 is fixedly connected at the bottom of the triangular support 6 by a U-shaped bolt.
