Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a flexible photovoltaic support and a flexible photovoltaic system. Background Technology

[0002] Flexible photovoltaic brackets are a solar module support system based on a tension structure design. They use flexible materials such as prestressed steel strands and cable trusses to replace traditional rigid brackets, and feature large spans, high clearance, and long row spacing.

[0003] For efficiency, photovoltaic panels need to track and face the sun. In current photovoltaic support methods, each support requires a separate motor to drive the panel to follow the sun. This is difficult to maintain and requires high investment. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides a flexible photovoltaic support and a flexible photovoltaic system. This flexible photovoltaic system uses four adjusting ropes to adjust the height of the four corners of the photovoltaic panel, thereby adjusting the orientation of the photovoltaic panel. Furthermore, the rollers on the support rods in the same column or row of the flexible photovoltaic system are driven by the same motor, ensuring uniform orientation of the photovoltaic panels throughout the entire system and reducing the number of motors required.

[0006] The above technical solution uses at least four adjusting ropes connected to the four corners of the photovoltaic panel. The orientation of the photovoltaic panel is controlled by changing the length of the adjusting ropes. The structure is simple and easy to install.

[0007] Furthermore, the upper end of the support rod is provided with a notch, and the rod walls on both sides of the notch are provided with opposing first connecting holes, and the fixed pulley is fixed between the two first connecting holes.

[0009] The above technical solution protects the adjustment rope inside the support rod, preventing the adjustment rope from being affected by external objects, thereby avoiding affecting the adjustment angle of the photovoltaic panel.

[0010] Furthermore, it also includes a limiting cable, one end of which is connected and fixed to the geometric center of the photovoltaic panel, and the other end of which is fixed to the support surface. The limiting cable can eliminate the impact of wind on the photovoltaic panel.

[0011] Furthermore, a damper is provided on the limiting cable.

[0025] Example: This example discloses a flexible photovoltaic system, such as... Figure 1 As shown, the flexible photovoltaic system includes multiple photovoltaic panels supported by flexible photovoltaic brackets, wherein the flexible photovoltaic brackets include: Four support rods arranged in a rectangular pattern, such as Figure 2 As shown, the photovoltaic panel 5 is square, and four support rods are respectively installed on the four sides of the photovoltaic panel 5. These are the first support rod, the second support rod, the third support rod, and the fourth support rod. In this application, the support rod is a support pipe 1. The lower end of the support pipe 1 is fixed to the ground by expansion bolts. Figure 3 As shown, the upper end of the support tube 1 is open and has a notch 11. The notch 11 extends downward from the opening, and the tube walls on both sides of the notch 11 are provided with opposing first connecting holes 12.

[0026] A fixed pulley 2 is connected between the two first connecting holes 12 on the support tube 1.

[0027] A second connecting hole is provided on the support tube 1 and below the fixed pulley 2. The second connecting hole intersects with the inner cavity of the support tube 1 and penetrates the support tube 1 radially.

[0028] A bearing is installed in the second connecting hole, and the inner wall of the bearing abuts against the scroll 3, meaning that the scroll 3 can rotate within the second connecting hole. One end of the scroll 3 is connected to a motor 31, which drives the scroll 3 to rotate clockwise or counterclockwise.

[0029] like Figure 4As shown, an adjusting rope 4 is fixed on the reel 3, and mounting holes are provided at the four corners of the photovoltaic panel 5. The end of the adjusting rope 4 facing away from the reel 3 passes over the fixed pulley 2 and is then connected and fixed to the mounting holes on the photovoltaic panel 5 via a wire buckle. Specifically, the adjusting ropes 4 on the four support tubes 1 are respectively connected and fixed to the mounting holes at the four corners of the photovoltaic panel 5.

[0030] A mounting hole is provided at the geometric center of the lower side of the photovoltaic panel 5. A limiting cable 6 is fixedly connected to the mounting hole, and the end of the limiting cable 6 facing away from the photovoltaic panel 5 is fixed to the ground with bolts. A damper 61 is provided on the limiting cable 6. The limiting cable 6, together with the damper 61, can eliminate the influence of wind on the photovoltaic panel 5 and prevent the photovoltaic panel 5 from rotating due to wind.

[0031] In some feasible embodiments, the adjusting rope 4 and the limiting cable 6 are steel cables.

[0032] With the above technical solution, the flexible photovoltaic bracket uses four adjusting ropes 4 to be connected to the four corners of the photovoltaic panel 5 respectively.

[0033] like Figure 1 As shown, multiple flexible photovoltaic supports in the flexible photovoltaic system are arranged in a matrix. The first support rod, second support rod, third support rod, and fourth support rod are respectively located on the front, right, rear, and left sides of the photovoltaic panel 5.

The connecting shaft and the reel 3 are connected by a universal coupling 71. The universal coupling 71 can achieve continuous rotation of the two connected shafts even when there is an angle between the axes, and reliably transmit torque and motion. Using the universal coupling 71 can eliminate the influence of terrain elevation on the connecting shaft 7.

[0034] Meanwhile, the reel 3 on the first support rod in the same row is driven by the same motor 31; the reel 3 on the second support rod in the same column is driven by the same motor 31; the reel 3 on the third support rod in the same row is driven by the same motor 31; and the reel on the fourth support rod in the same column is driven by the same motor 31.

[0035] The flexible photovoltaic system also includes a controller, and each of the motors is connected to the controller. The controller is used to control the motors to drive the rollers connected to the motors to rotate, thereby changing the length of the adjusting rope 4 to adjust the orientation of the photovoltaic panel 5.

[0036] Through the above technical solution, the rollers 3 on the same type of support rod in the same row or column are driven by the same motor 31, thereby reducing the number of motors required for the entire flexible photovoltaic system, reducing costs, and facilitating maintenance.
