Description

Technical Field

[0001] The utility model relates to a connecting component and a three-cable flexible bracket, belonging to the technical field of photovoltaic brackets. Background Art

[0002] The prestressed steel cable flexible support system is a support system that fixes the components on the tensioned steel cables. The entire support system consists of terminal columns, intermediate columns, stabilizing (wind-resistant) cables, and inter-column stabilization systems. Each span can carry half a string to one string of photovoltaic modules. It is widely used in various scenarios such as large mountain power stations, fishery-photovoltaic complementary power stations, pastoral-photovoltaic complementary power stations, sewage treatment plants, etc., effectively improving the comprehensive land utilization rate and the installed capacity of power stations.

[0003] At present, most manufacturers use an inverted arch structure with three cables. The windproof cables at the bottom of this structure cannot resist the pull when the photovoltaic modules are sucked by the wind, which will cause damage to the system in extreme weather. In order to solve the above problem, some manufacturers use triangular supports to reinforce single-row photovoltaic brackets. However, in actual use, it is found that the windproof system with a single row as the overall structure is less effective in the face of strong winds and has poor seismic performance.

[0004] In order to solve the above problems, the present application proposes a connecting member and a three-cable flexible bracket. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a connecting component and a three-cable flexible bracket, which has smaller wind vibration when facing strong winds, can better play the role of wind resistance and strong wind protection, improve the structural strength and load capacity of the overall flexible photovoltaic bracket, and can effectively solve the problems in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A connecting member includes a triangular support system consisting of a first support rod, a second support rod, and a first connecting rod. Adjacent triangular support systems are fixedly connected by a first connecting member, a second connecting member, a second connecting rod, a third connecting rod, and a horizontal connecting rod.

[0010] As a further improvement of the present utility model, both the first connecting block and the second connecting block are composed of a vertical plate, a bottom plate, and an ear plate. The bottom plate is fixedly connected to the bottoms of the ear plate and the vertical plate, and two ear plates are provided and fixedly connected to the vertical plate.

[0011] As a further improvement of the present utility model, one ends of the first support rod, the second support rod, the horizontal connecting rod, and the third connecting rod are all fixedly connected to the second connecting member.

[0016] As a further improvement of the present utility model, a ground anchor pile is arranged between the intermediate column and the terminal column, and both ends of the connecting member are fixedly connected to the ground anchor pile through steel strands.

[0017] The beneficial effects of the present utility model: A connecting member and a three-cable flexible support form a connecting member by combining and connecting the triangular support systems on multiple rows of flexible photovoltaic supports. The connecting member combines multiple rows of flexible photovoltaic supports into an integral structure, and finally connects both ends of the connecting member to the ground anchor pile through steel strands to form a stable flexible support anti-wind system.

[0030] Embodiment 1

[0031] As Figures 1-7 shown, a connecting member is mainly used to combine and connect the triangular support systems for connecting the load-bearing cable 19 and the stabilizing cable 20 on a single-row flexible photovoltaic support. Multiple rows of flexible photovoltaic supports form an integral structure through the connecting member 23, including a triangular support system composed of a first support rod 1, a second support rod 2, and a first connecting rod 3. Adjacent triangular support systems are fixedly connected through a first connecting piece 7, a second connecting piece 8, a second connecting rod 5, a third connecting rod 6, and a horizontal connecting rod 4. A plurality of triangular support systems are combined and connected to form the connecting member 23. The first connecting piece 7 is located above the second connecting piece 8. The multiple rows of flexible photovoltaic supports are combined into an integral structure through the connecting member 23, with less wind vibration when facing strong winds, and can better play the role of wind resistance and strong wind protection, improving the structural strength of the overall flexible photovoltaic support.

[0032] In some alternative embodiments, the first connecting piece 7 is composed of a U-shaped block 9 and an upper cover plate 10. The upper cover plate 10 is fixedly connected to the top of the U-shaped block 9 by bolts, and a wire passing hole for the steel strand to pass through is also provided between the U-shaped block 9 and the upper cover plate 10.

[0033] In some optional embodiments, the second connecting member 8 is composed of a first connecting block 11 and a second connecting block 12. The first connecting block 11 and the second connecting block 12 are fixedly connected by bolts. A wire threading hole is also provided between the first connecting block 11 and the second connecting block 12 for the steel strand to pass through.

[0034] Optionally, the first connecting block 11 and the second connecting block 12 are both composed of a vertical plate 13, a bottom plate 15, and an ear plate 14, the bottom plate 15 is fixedly connected to the ear plate 14 and the bottom of the vertical plate 13, and the ear plate 14 is provided in two pieces and fixedly connected to the vertical plate 13.

[0035] Specifically, the horizontal connecting rod 4 is fixedly connected to the base plate 15 by bolts, and the second connecting rod 5 and the third connecting rod 6 are connected to the ear plate 14 by bolts. The spacing between the ear plates 14 is greater than the minimum distance between any two points on the outer circle of the bolt head and less than the maximum distance, so that the rotation of the bolt can be limited when the bolt is passed through the base plate 15, which facilitates the installation of the base plate 15 and the horizontal connecting rod 4.

[0036] Furthermore, the load-bearing rope 19 and the stabilizing rope 20 are both configured as steel wire ropes, and arc-shaped clamping portions 16 are provided on the U-shaped block 9, the upper cover plate 10, and the vertical plate 13. After the U-shaped block 9 and the upper cover plate 10 are installed by bolts, the clamping portion 16 forms a threading hole for the load-bearing rope 19 to pass through. After the first connecting block 11 and the second connecting block 12 are connected by bolts to form the second connecting member 8, the clamping portion 16 on the vertical plate 13 forms a threading hole for the stabilizing rope 20 to pass through.

[0037] In some optional embodiments, one end of the first support rod 1 , the second support rod 2 , the horizontal connecting rod 4 , and the third connecting rod 6 are all fixedly connected to the second connecting member 8 .

[0038] In some optional embodiments, the first support rod 1, the second support rod 2, the first connecting rod 3, the horizontal connecting rod 4, the second connecting rod 5, and the third connecting rod 6 are all configured as round tubes, and the ends of the first support rod 1, the second support rod 2, the first connecting rod 3, the horizontal connecting rod 4, the second connecting rod 5, and the third connecting rod 6 are all flattened.

[0039] Example 2

[0040] like Figure 8 As shown, a three-cable flexible bracket includes the above-mentioned connecting member 23, and also includes an intermediate column 17 and a terminal column 18. The intermediate column 17 is arranged between the terminal columns 18. A load-bearing cable 19 is also fixedly connected between the terminal columns 18, and a photovoltaic component 21 is fixedly installed on the top of the load-bearing cable 19.

[0041] In some alternative embodiments, a stabilizing cable 20 is provided between the terminal column 18 and the intermediate column 17. The stabilizing cable 20 is in a suspended state under normal conditions, and the load-bearing cable 19 is in a tensioned state under normal conditions. Under high-wind conditions, the stabilizing cable 20 deforms under force to bear the load, improving the structural strength of the single-row flexible support.

[0042] In some alternative embodiments, the connecting member 23 is connected to the load-bearing cable 19 through a first connecting piece 7, and the connecting member 23 is connected to the stabilizing cable 20 through a second connecting piece 8.

[0043] In some alternative embodiments, an anchor pile 22 is provided between the intermediate column 17 and the terminal column 18. Both ends of the connecting member 23 are fixedly connected to the anchor pile 22 through steel strands.

[0044] By combining and connecting the triangular support systems on multiple rows of flexible photovoltaic supports to form the connecting member 23, the connecting member 23 combines multiple rows of flexible photovoltaic supports into an integral structure. Finally, both ends of the connecting member 23 are connected to the anchor pile 22 through steel strands to form a stable flexible support wind-resistant system. When facing strong winds, the wind vibration is smaller, which can better play the role of wind resistance and strong wind protection, and improve the structural strength of the overall flexible photovoltaic support.
