In strong winds, the cable is also prone to large-amplitude vibrations. Under long-term vibrations, component microcracks are likely to occur, resulting in the failure of some solar cells, accelerating the aging of the components, and causing serious waste of resources. To solve the above problems, a damping structure for a flexible photovoltaic bracket is proposed. Content of the Utility Model

[0019] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0020] Refer to Figures 1-4As shown in the figure, a damping structure for a flexible photovoltaic support includes a box body 1. Through holes 2 are formed through both the left and right sides of the box body 1. The aperture of the through hole 2 is larger than the diameter of the steel cable, ensuring that when the steel cable is subjected to a large force, it can move within a certain range to reduce the shear force and avoid the steel cable from breaking. At both ends of the lower side inside the box body 1, fixing rods 4 are fixedly connected. On the upper side of the fixing rod 4, a lower arc-shaped clamping plate 5 is fixedly connected to fix the steel cable and limit it within a certain range to prevent excessive deflection. On the upper side of the lower arc-shaped clamping plate 5, a first protective pad 6 is fixedly connected to effectively protect the surface of the steel cable. At both ends of the upper side inside the box body 1, push rods 7 are fixedly installed. The output end of the push rod 7 is fixedly connected to an upper arc-shaped clamping plate 8 to fix the steel cable and limit it within a certain range to prevent excessive deflection. The upper arc-shaped clamping plate 8 is located directly above the lower arc-shaped clamping plate 5. On the lower side of the upper arc-shaped clamping plate 8, a second protective pad 9 is fixedly connected to effectively protect the surface of the steel cable.

[0021] Specifically, damping components 3 are arranged at the central positions on both sides of the upper side of the box body 1. The damping component 3 includes two fixing plates 301, which are fixedly connected to the surface of the box body 1. The two fixing plates 301 are symmetrically arranged in the front and back along the horizontal direction. A first fastening bolt 302 is threadedly connected to the front side of the front fixing plate 301. The end of the first fastening bolt 302 penetrates through the front side of the front fixing plate 301 and is threadedly connected to the front side of the rear fixing plate 301. A first rotating ring 303 is rotatably connected to the first fastening bolt 302. The front and back sides of the first rotating ring 303 are rotatably connected to the inner sides of the two fixing plates 301. One end of the first rotating ring 303 away from the box body 1 is fixedly connected to a first connecting rod 304. One end of the first connecting rod 304 away from the box body 1 is fixedly connected to a damper 305 to effectively perform a vibration damping function.

[0022] Specifically, one end of the damper 305 away from the box body 1 is fixedly connected to a second connecting rod 306. One end of the second connecting rod 306 away from the box body 1 is fixedly connected to a second rotating ring 307. The front and back sides of the second rotating ring 307 are rotatably connected to a rotating frame 308. A second fastening bolt 309 is threadedly connected to the front side of the rotating frame 308. The end of the second fastening bolt 309 penetrates through the front side of the rotating frame 308 and the inside of the second rotating ring 307 and is threadedly connected to the rear side inside the rotating frame 308. At the central position of one end of the rotating frame 308 away from the box body 1, a rigid connecting rod 310 is fixedly connected. An installation plate 311 is fixedly connected to the outside of the rigid connecting rod 310. Installation holes 312 are formed through the four corner positions on the upper side of the installation plate 311, which is convenient for connecting the installation plate 311 to rigid bodies at different angles and transmitting the vibration kinetic energy released by the damper 305 to the rigid body.

[0023] Working principle: Place the box body 1 at the mid-span position of the steel cable, so that the steel cable passes through the perforation 2. The lower side of the steel cable is placed on the first protective pad 6. The push rod 7 drives the upper arc-shaped clamping plate 8 to move downward, so that the second protective pad 9 abuts against the upper side of the steel cable. A tension sensor is installed on the steel cable. Rotate the damper 305 so that the mounting plates 311 at the upper and lower ends are connected to the rigid main body at different angles through the mounting holes 312. When the steel cable is in a strong wind environment and the steel cable is subjected to tension and is about to undergo deflection changes, the steel cable is fixed by the upper arc-shaped clamping plate 8 and the lower arc-shaped clamping plate 5, and the box body 1 is connected to the rigid main body through the damping assembly 3, and the steel cable will not undergo large deflection changes. When the tension on the steel cable is relatively large and the shear force on the steel cable at the perforation 2 position is relatively large, the push rod 7 will control the upper arc-shaped clamping plate 8 to move upward within a certain range, so that the steel cable can move within a certain range, reducing the shear force while not affecting the function of the steel cable structure. When the steel cable is vibrated, the vibration will be transmitted to the damper 305 through the box body 1. The damper 305 can effectively reduce vibration. Part of the vibration kinetic energy released by the damper 305 is absorbed and offset, and part is transmitted to the rigid main body through the rigid connecting rod 310 and the mounting plate 311, avoiding hidden cracks in the components.
