Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a flexible photovoltaic support wind-resistant ground anchor structure. Background Technology

[0002] With the rapid development of photovoltaic power generation technology, flexible photovoltaic supports have been widely used in scenarios such as fishery-solar complementary projects and mountain photovoltaic projects due to their advantages such as large span, adaptability to complex terrain and convenient construction. However, the lightweight nature of flexible supports makes them prone to structural instability in strong wind environments, and the wind resistance performance of ground anchors has become a problem that restricts their safety.

[0003] Traditional flexible support anchors often use uniformly arranged pile foundations or single cable structures, which cannot effectively cope with the regional distribution of wind loads (such as concentrated wind pressure at the edges), resulting in insufficient pull-out resistance of the pile foundations or a high risk of cable breakage. In addition, existing anchor designs ignore the need for utilization of the space below, such as the pile foundation arrangement in the fishery-solar complementary scenario, which may obstruct the passage of fishing boats or affect the activities of aquatic organisms. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flexible photovoltaic support wind-resistant ground anchor structure, which aims to improve the problem that the existing technology of traditional flexible support ground anchors mostly adopts uniformly arranged pile foundations or single cable structures, which cannot effectively cope with the regional distribution of wind loads (such as concentrated wind pressure at the edges), resulting in insufficient pull-out resistance of pile foundations or high risk of cable breakage.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flexible photovoltaic support wind-resistant ground anchor structure includes:

[0007] The ground surface is used to fix the flexible photovoltaic support;

[0008] Multiple wind-resistant cable piles are fixedly connected to the top of the ground.

[0009] A horizontal connecting rod and multiple hinge blocks are provided, wherein the horizontal connecting rod is disposed on top of multiple wind-resistant cable piles, and the multiple hinge blocks are installed on both sides of the upper part of the horizontal connecting rod;

[0010] Multiple wind-resistant cables and two wind-resistant steel wire ropes are provided. One end of the multiple wind-resistant cables is installed on the top of the multiple wind-resistant cable piles, and the other end of the multiple wind-resistant cables is installed on the bottom of the horizontal connecting rod. One end of the two wind-resistant steel wire ropes is installed on the top of the wind-resistant cable piles on the left and right sides respectively, and the other end of the two wind-resistant steel wire ropes is installed on the outer sides of the horizontal connecting rod.

[0011] And a support component for supporting the photovoltaic panel.

[0012] Furthermore, the support assembly includes a first strut, which is rotatably connected inside the plurality of hinge blocks. A second strut is rotatably connected to the middle of each of the plurality of hinge blocks. A short diagonal tie rod is rotatably connected to the left side of each of the plurality of hinge blocks. A plurality of long diagonal tie rods are rotatably connected to the middle of the plurality of short diagonal tie rods. The plurality of long diagonal tie rods are rotatably connected inside the plurality of hinge blocks.

[0013] Furthermore, the wind-resistant cables are installed in one row at the edge of the photovoltaic array and in every other row in the inner area.

[0014] Furthermore, the plurality of first struts, the plurality of second struts, the plurality of long diagonal braces, and the plurality of short diagonal braces are connected by wind-resistant crossbeams.

[0015] Furthermore, the wind-resistant beam is connected to the wind-resistant cable piles by wind-resistant steel wire ropes to form a triangular tie structure.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, when wind force acts on the photovoltaic panel, the load is transmitted to the wind-resistant beam through the support, and then to the wind-resistant cable pile through the wind-resistant steel wire rope. Finally, it is dispersed to the ground by the spiral ground anchor or concrete foundation. The short diagonal tie rod, long diagonal tie rod, horizontal connecting rod and strut work together to convert the lateral load into axial force, forming multi-directional constraints, preventing stress concentration and improving the anti-overturning ability, and enhancing the bending resistance of the overall structure of the support.

[0018] 2. In this utility model, according to the regional distribution law of wind load on photovoltaic array, a ground anchor cable is set in each of the three rows at the edge where the wind load is large, and a ground anchor cable arrangement scheme of one every other in the inner area where the wind load is small is adopted. The ground anchor cables in the three rows around the perimeter ensure support in multiple directions, while the ground anchor cables in the inner area provide additional stability to prevent bending or deformation of the structure and ensure the stability of the support.

[0019] 3. In this utility model, the arrangement of the ground anchor cables with sparse outer layers and dense inner layers allows for a larger clearance in the middle area of ​​the photovoltaic array, ensuring unobstructed access in the lower area. This is conducive to the growth and activity of aquatic organisms and facilitates fishermen's operations. Through reasonable arrangement and spacing, the number of ground anchor cables is optimized, and the number of pile foundations is reduced, shortening the construction period and lowering construction costs. At the same time, it reduces the impact on the surrounding environment. Especially in ecologically sensitive areas, this design scheme is both economical and environmentally friendly.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a flexible photovoltaic support wind-resistant anchor structure, comprising: a ground 1 for fixing the flexible photovoltaic support; multiple wind-resistant cable piles 2 fixedly connected to the top of the ground 1; a horizontal connecting rod 5 and multiple hinge blocks 11, the horizontal connecting rod 5 being disposed on the top of the multiple wind-resistant cable piles 2, and the multiple hinge blocks 11 being installed on the upper sides of the horizontal connecting rod 5; multiple wind-resistant cables 4 and two wind-resistant steel wire ropes 3, one end of the multiple wind-resistant cables 4 being installed on the top of the multiple wind-resistant cable piles 2, and the other end of the multiple wind-resistant cables 4 being installed on the bottom of the horizontal connecting rod 5, one end of the two wind-resistant steel wire ropes 3 being respectively installed on the top of the left and right wind-resistant cable piles 2, and the other end of the two wind-resistant steel wire ropes 3 being installed on the outer sides of the horizontal connecting rod 5; and a support. The support assembly is used to support the photovoltaic panels. The support assembly includes a first support rod 9, which is rotatably connected to the interior of multiple hinge blocks 11. A second support rod 10 is rotatably connected to the middle of each of the multiple hinge blocks 11. A short diagonal tie rod 6 is rotatably connected to the left side of each of the multiple hinge blocks 11. A multiple long diagonal tie rod 7 is rotatably connected to the middle of the multiple short diagonal tie rods 6. The multiple long diagonal tie rods 7 are rotatably connected to the interior of the multiple hinge blocks 11. Wind-resistant cables 4 are installed in each row at the edge of the photovoltaic array and in every other row in the inner area. The multiple first support rods 9, multiple second support rods 10, multiple long diagonal tie rods 7 and multiple short diagonal tie rods 6 are connected to each other by a wind-resistant crossbeam 8. The wind-resistant crossbeam 8 is connected to the wind-resistant cable pile 2 by a wind-resistant steel wire rope 3 to form a triangular tie structure.

[0027] Specifically, when wind acts on the photovoltaic panel, it generates a wind load perpendicular to the panel surface. This load is transferred to the main beam of the support through the rigid connection nodes of the support, and further concentrated at the load-bearing nodes of the wind-resistant beam 8. The two ends of the wind-resistant beam 8 form a cable-stayed structure with the wind-resistant steel wire rope 3 and the wind-resistant cable pile 2. The high tensile strength of the steel wire rope is used to convert the horizontal wind load into a pull-out force on the pile foundation. The short diagonal tie rod 6 and the long diagonal tie rod 7 are connected to the horizontal connecting rod 5 and the first support rod 9 and the second support rod 10 at different inclination angles to form a spatial truss structure. The two work together to decompose the wind load into axial pressure, avoiding bending and torsional deformation of the support. The horizontal connecting rod 5, as a transverse connecting member, ensures the balanced distribution of load between adjacent first support rod 9 and second support rod 10, prevents local overload, and enhances the overall anti-overturning capacity. At the same time, the arrangement of the ground anchor cables with sparse outer layers and dense inner layers allows for a larger clearance in the middle area of ​​the photovoltaic array, ensuring unobstructed access in the lower area, which is conducive to the growth and activity of aquatic organisms and facilitates fishermen's operations.

[0028] Working principle: When wind force acts on the photovoltaic panel, the load is transferred to the wind-resistant beam 8 through the support; the wind-resistant beam 8 transfers the tension to the wind-resistant cable pile 2 through the wind-resistant steel wire rope 3, and the pile foundation distributes the load to the ground 1 through the spiral ground anchor or concrete gravity foundation; the short diagonal tie rod 6, the long diagonal tie rod 7, the horizontal connecting rod 5, and the first support rod 9 and the second support rod 10 work together to convert the lateral load into axial tension or compression, forming multi-directional constraints, avoiding local stress concentration, and enhancing the overall anti-overturning ability. At the same time, the height of the middle area of ​​the photovoltaic panel support is limited by the vertical position of the wind-resistant beam 8 and the length of the short diagonal tie rod 6 and the long diagonal tie rod 7, ensuring unobstructed space below and meeting the needs of fishery operations and ecological protection.
