Description

Technical Field

[0001] This utility model relates to a fixed flexible photovoltaic support structure, belonging to the field of photovoltaic support technology. Background Technology

[0002] Flexible photovoltaic (PV) brackets, as a novel type of PV support structure, have been widely used in PV power generation systems due to their flexible design, high material utilization, and convenient installation. Currently, the connection between flexible PV brackets and the ground is typically achieved through hinged connections. The advantage of this hinged connection method lies in its ability to effectively save steel, as its design releases the bending moment at the column base, reduces the internal forces at the column feet, and allows for smaller column base cross-sections and column foot nodes, thus reducing the overall material cost and processing difficulty. However, this design also has certain drawbacks in practical applications. When flexible PV brackets are subjected to external environmental forces such as strong winds, the flexibility of the hinged connection can easily cause the PV modules to sway significantly, resulting in uneven stress on the bracket structure or even overload, potentially leading to instability or collapse of the flexible bracket. This safety hazard not only affects the operational stability of the PV power station but may also lead to high maintenance costs and economic losses. Therefore, optimizing the wind resistance design of flexible PV brackets, especially suppressing the swaying of PV modules in strong winds, has become an important technical issue that urgently needs to be addressed. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a fixed flexible photovoltaic support structure to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is:

[0005] A fixed flexible photovoltaic support structure is provided, including a flexible support group. Each flexible support group includes two horizontal cables, several support frames, and two or more support frames. The support frames are arranged in a line, and the two horizontal cables are set on the support frames. The support frames are fixedly connected to the two horizontal cables.

[0006] The support frame includes a central column and a crossbeam. The middle part of the crossbeam is fixedly connected to the upper end of the central column, and the lower end of the central column is fixedly connected to the ground. Concrete is poured into the inner cavity of the lower part of the central column.

[0007] Furthermore, the support frame located at both ends of each set of flexible supports also includes an inner support rod, one end of which is connected to the top of the support frame, and the other end of which is connected to the ground located between the two ends of each set of flexible supports.

[0008] Furthermore, the inner strut is made of concrete.

[0009] The beneficial effects of this utility model are: compared with the prior art,

[0010] 1) This utility model directly fixes the central column to the ground. The central column is fixed to the ground, which can reduce the overall swaying of the flexible support. On the other hand, the concrete is poured into the central column, which not only improves the anti-sway performance of the flexible photovoltaic support, but also improves the bending performance of the central column, thus preventing the central column from breaking in strong winds.

[0011] 2) This utility model reduces land waste on both sides of the flexible photovoltaic support by replacing the traditional external cable-stayed cable with an internal support rod, thus saving land resources. At the same time, since the internal support structure is mainly pressure, the internal support rod can be made of concrete, thereby saving steel and reducing costs. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the end support frame of this utility model;

[0014] Figure 3 This is a schematic diagram of the cable structure of this utility model. Detailed Implementation

[0015] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0016] Implementation Example 1: Reference Figure 1-3 This embodiment adopts a fixed flexible photovoltaic support structure, including a flexible support group. Each flexible support group includes two horizontal cables, several support frames 3 and two or more support frames. The support frames are arranged in a line. The two horizontal cables are set on the support frames. The support frames 3 are fixedly connected to the two horizontal cables.

[0017] The support frame includes a central column 5-1 and a crossbeam 5-2. The crossbeam 5-2 is fixedly connected to the upper end of the central column 5-1 in the middle, and the lower end of the central column 5-1 is fixedly connected to the ground. Concrete 5-3 is poured into the inner cavity of the lower part of the central column 5-1.

[0018] By directly fixing the central column to the ground, the overall swaying of the flexible support structure can be reduced. On the other hand, pouring concrete into the central column not only improves the anti-sway performance of the flexible photovoltaic support structure, but also improves the bending performance of the central column, preventing the central column from breaking in strong winds.

[0019] Furthermore, the support frame located at both ends of each set of flexible supports also includes an inner support rod 7, one end of which is connected to the top of the support frame, and the other end of which is connected to the ground located between the two ends of each set of flexible supports.

[0020] By replacing the traditional external cable-stayed structure with an internal support strut, land waste on both sides of the flexible photovoltaic support is reduced, saving land resources. At the same time, since the internal support structure is mainly under pressure, the internal support strut 7 can be made of concrete, thereby saving steel and reducing costs.

[0021] Furthermore, the inner strut 7 is made of concrete.

[0022] Furthermore, the flexible support group includes one or more groups, and each group of flexible supports is parallel to each other in the length direction;

[0023] It also includes two sets of wind cables, each set consisting of two wind cables 2. The lower ends of the two wind cables 2 are fixedly connected to the ground below the support frame 3 by anchor bolts 5. The upper ends of the two wind cables 2 are fixedly connected to the left and right sides of the support frame 3 respectively. The wind cables 2 are in a tensioned state.

[0024] The left and right sides of the support frame are fixedly connected by wind cables, and a tension force is applied to the left and right sides of the photovoltaic bracket to prevent the photovoltaic bracket from moving in the opposite direction of the wind cable tension due to wind force, which would cause the photovoltaic bracket to deform and be damaged.

[0025] Furthermore, the wind cable group 2 includes one or more groups, with each support frame 3 corresponding to one group of wind cable 2.

[0026] Furthermore, it also includes a set of stabilizing cables 1, which consists of two stabilizing cables 1. The two stabilizing cables 1 are respectively set at the flexible support groups at the outermost edges on the left and right sides of the tension cable protection structure. One end of the stabilizing cable 1 is connected to the support frame 3 of the flexible support group on the corresponding side, and the other end of the stabilizing cable 1 is fixedly connected to the ground on the corresponding side through a stabilizing side pile 6. The end of the stabilizing cable 1 connected to the stabilizing side pile 6 is farther from the center of the tension cable protection structure than the end connected to the support frame 3.

[0027] By stabilizing cables, the support frame of the flexible support group is pulled on both sides, providing tensile constraints to both sides of the photovoltaic module, thereby improving the anti-sway performance of the flexible support when subjected to external wind forces.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the scope of protection of the present invention. The present invention relates to a fixed flexible photovoltaic support structure, belonging to the field of photovoltaic support technology.
