[0019] Example:

[0020] Please see Figure 1 - Figure 3This utility model provides a technical solution: a flexible photovoltaic support system on water, including two end beams 5 and a middle beam 11.

A number of wind-resistant trusses are arranged between the end beams 5 and the middle beam 11, and the number of wind-resistant trusses are arranged in parallel.

[0021] The wind-resistant truss includes a wind-resistant crossbeam 7, with wind-resistant diagonal braces 8 symmetrically connected to both ends of the wind-resistant crossbeam 7. The lower ends of the two wind-resistant diagonal braces 8 are connected together. Several component cables 1 are fixedly connected between the two end beams 5. The two ends of the wind-resistant crossbeam 7 are respectively connected to two adjacent component cables 1. Several load-bearing cables 2 are fixedly connected between the two end beams 5. The lower end of the wind-resistant diagonal brace 8 is connected to the load-bearing cable 2.

[0022] Several tie rods 6 are fixedly connected to the end beam 5. The end of the tie rod 6 away from the end beam 5 is connected to the ground. A wind-resistant diagonal tie rod 9 is provided between every two adjacent wind-resistant trusses. One end of the wind-resistant diagonal tie rod 9 is connected to the lower end of the wind-resistant diagonal brace 8, and the other end of the wind-resistant diagonal tie rod 9 is connected to the wind-resistant crossbeam 7 of another wind-resistant truss.

[0023] In this embodiment, component cable 1 and load-bearing cable 2 are connected by end pile 4 and middle pile 10. Component cable 1 and load-bearing cable 2 are connected together at the top of end pile 4 and are directly supported by tie rod 6. The lateral stability of end pile 4 is ensured by end beam 5. Component cable 1 and load-bearing cable 2 are connected by wind-resistant crossbeam 7 and wind-resistant diagonal brace 8 to form a stable triangular system. They are connected by wind-resistant diagonal tie rod 9. Component cable 1 and load-bearing cable 2 are connected together on middle beam 11. The lateral stability of middle pile 10 is ensured by setting middle beam 11.

[0024] In this embodiment, the wind-resistant truss also includes a reverse wind-resistant cable 3. One end of the reverse wind-resistant cable 3 is fixedly connected to the end pile 4, and the other end of the reverse wind-resistant cable 3 is connected to the lower end of the wind-resistant diagonal brace 8.
