[0017] Please refer to the attached Figure 1, the prestress adjusting device for the flexible support steel strand 1 of a photovoltaic power station, comprising a fixing device, a guiding device, the steel strand 1, and a tensioning and adjusting device. The fixing device and the tensioning and adjusting device are respectively fixed at both ends of the steel strand 1, the guiding device is arranged on the steel strand 1, and the guiding device is located at the middle position between the fixing device and the tensioning and adjusting device;

[0018] The tensioning and adjusting device includes a jack 2, a piston 3, a wedge grip 4 and a fixture 5. The piston 3 is arranged inside the cylinder body of the jack 2. The steel strand 1 passes through the jack 2 and the wedge grip 4. A number of through holes are opened on the wedge grip 4, the steel strand 1 passes through the through holes, and the fixture 5 fixes the steel strand 1 on the wedge grip 4. The piston 3 is connected to the wedge grip 4.

[0019] Adopting the above technical solution, the steel strand 1 is the core part of the entire adjusting device. It passes through the fixing device, the guiding device, the jack 2 and the wedge grip 4. The tension of the steel strand 1 directly affects the stability of the photovoltaic support. The purpose of the fixing device is to fix one end of the steel strand 1 on the beam body. The function of the guiding device is to guide the steel strand 1 to move along a predetermined path and prevent the steel strand 1 from deviating during the tensioning process. The tensioning and adjusting device is the key part for adjusting the tension of the steel strand 1. The piston 3 is arranged inside the cylinder body of the jack 2. The steel strand 1 passes through the jack 2 and the wedge grip 4. The function of the fixture 5 is to fix the steel strand 1 on the wedge grip 4, and the piston 3 is connected to the wedge grip 4. By moving the piston 3, the tension of the steel strand 1 can be adjusted. By operating the jack 2, the piston 3 can be pushed to move inside the cylinder body, thereby stretching or compressing the steel strand 1. When the piston 3 moves outwards, the steel strand 1 is stretched, increasing its tension; when the piston 3 moves inwards, the steel strand 1 is relaxed, reducing its tension. A number of through holes are opened on the wedge grip 4, and these through holes allow the steel strand 1 to pass through. At the same time, the fixture 5 fixes the steel strand 1 on the wedge grip 4 to ensure that the steel strand 1 will not slip during the tensioning process. In this application, the tension of the steel strand 1 is controlled by the tensioning and adjusting device, and the position and direction of the steel strand 1 are ensured by the fixing device and the guiding device, finally realizing the stable support of the flexible support of the photovoltaic power station. Through real-time monitoring and adjustment, it can be ensured that the photovoltaic support can maintain the best state under various environmental conditions.

[0020] In some embodiments, the guiding device includes a guide wheel 6, and the steel strand 1 bypasses the guide wheel 6 to ensure its smooth movement.

[0021] In some embodiments, the fixing device includes a fixing plate 7 and fixing bolts 8. The steel strand 1 is fixed on the fixing plate 7, and the fixing bolts 8 fix the fixing plate 7 on the beam body. The number of the fixing bolts 8 is at least two.

[0022] With the above technical solution, the steel strand 1 passes through the hole of the fixing plate 7, and then the fixing plate 7 is fastened to the beam body using the fixing bolts 8. The number of the fixing bolts 8 is at least two to ensure sufficient stability and tensile resistance.

[0023] In some embodiments, a force sensor 9 is provided at a position on the steel strand 1 close to the jack 2. The force sensor 9 is used to monitor the tension of the steel strand 1 in real time. By reading the data of the force sensor 9, the tension of the steel strand 1 can be controlled and adjusted more precisely to ensure that it is within a safe range.
