Description

Technical Field

[0001] This utility model relates to the field of photovoltaic brackets, and specifically refers to a novel flexible photovoltaic bracket system. Background Technology

[0002] Common flexible photovoltaic support systems are single-layer suspension structures or cable-column structures.

[0003] Single-layer cable-stayed structures typically consist of a main steel frame made up of beams and columns, cable stays, and cables. The cables are two parallel cables parallel to the plane of the components. They employ a fully flexible system with a single stress mode, resulting in weak overall structural stiffness. Under wind pressure or suction, they are prone to significant deformation, making it difficult to achieve larger spans.

[0004] The cable-and-column configuration connects cables directly or indirectly to columns, typically employing a layout with more columns and fewer beams. The tension of the cables is transferred to the supporting structure through the steel columns. However, due to the increased number of foundations, the requirements for foundation design and construction are higher. In situations with overly complex or irregular terrain, the cable-and-column configuration can be limited.

[0005] Therefore, this utility model proposes a novel flexible photovoltaic support system. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of flexible photovoltaic support system, which solves the problems of weak overall structural rigidity and high requirements for foundation design and construction of existing flexible photovoltaic supports.

[0007] The technical solution to achieve the above objectives is:

[0008] This utility model provides a novel flexible photovoltaic support system, comprising: two end supports arranged opposite to each other; at least one middle support supported between the two end supports, wherein when there are two or more middle supports, they are spaced apart between the two end supports; a plurality of upper load-bearing cables spaced apart between the two end supports, with both ends connected to the corresponding end supports and the middle connected to the top of the corresponding middle support, and corresponding two upper load-bearing cables forming a group, with photovoltaic modules installed on the same group of upper load-bearing cables; and a plurality of lower load-bearing cable mechanisms arranged between adjacent end supports and middle supports, wherein when there are two or more middle supports, a lower load-bearing cable mechanism is also arranged between adjacent two middle supports, and the lower load-bearing cable mechanism is connected to the corresponding upper load-bearing cable, and also connected to the corresponding end supports and middle supports.

[0009] Furthermore, both end supports are equipped with cable-stayed mechanisms, which are located on the side away from the middle support, with one end connected to the end support and the other end connected to the ground.

[0010] Furthermore, the cable-stayed structure includes: a plurality of ground anchor piles, which are buried at intervals in the ground; and a plurality of cable bodies, one end of which is connected to the corresponding ground anchor pile, and the other end of which is connected to the end support.

[0011] Furthermore, each lower load-bearing cable mechanism includes: several lower load-bearing cable bodies, with both ends connected to corresponding end supports and middle supports respectively, and distributed at intervals between each other; several spaced-out connecting frames, spaced between the upper load-bearing cables and the lower load-bearing cable bodies, and perpendicular to the several upper load-bearing cables.

[0012] Furthermore, the dimensions of several connecting frames decrease sequentially from the center to both sides, and the lower load-bearing cable body is arc-shaped.

[0013] Furthermore, each connecting frame includes several triangular supports. The upper end of each triangular support is connected to two upper load-bearing cables in the same group, and the lower end is connected to the corresponding lower load-bearing cable body. Two connecting rods are provided between each pair of adjacent triangular supports. The two connecting rods are distributed crosswise and their ends are connected to the corresponding triangular supports.

[0014] Furthermore, the central support is provided with several support frames, and each set of upper load-bearing cables is connected to the support frame.

[0015] Furthermore, the support frame includes: a vertical rod supported on the central support; a support rod at the top of the vertical rod; two stabilizing rods respectively located at both ends of the support rod and connected to the central support; and three rope clamps located on the support rod.

[0016] Furthermore, the support rod is inclined, and the two upper load-bearing cables in each group are at different heights, so that the photovoltaic modules installed on the upper load-bearing cables are inclined.

[0017] Furthermore, it also includes several windproof cables, one end of which is connected to the lower load-bearing cable mechanism, and the other end is connected to the ground.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By setting up a lower load-bearing cable mechanism, which is connected between the end support and the middle support and connected to the upper load-bearing cable, part of the cable force of the upper load-bearing cable is distributed, thereby increasing the rigidity of the overall structure.

[0020] By installing windproof cables to pull the lower load-bearing cable mechanism, the photovoltaic modules are prevented from swaying due to factors such as wind force or the weight of snow accumulation, thus avoiding the impact of swaying on the stability of the structure and further ensuring the overall stability of the structure.
