Technical Field

[0001] This utility model relates to the field of photovoltaic brackets, and in particular to a mid-span triangular brace for a three-cable flexible photovoltaic bracket. Background Technology

[0002] For large-span (over 35m) cable structures of photovoltaic flexible supports, in addition to the two main cables, a third stabilizing cable is required to ensure the safety of the cable structure (stability of the support under wind pressure, snow pressure, and wind vibration). This is called a three-cable system, which means that a load-bearing stabilizing cable of equal or higher strength is set below the two main cables.

[0003] To achieve stability of the third cable, it is necessary to closely connect the third cable with the two main cables to achieve a uniform distribution of force among the three cables.

[0004] Currently, the third cable support scheme using a square pyramid is available on the market, but it is costly, complex to construct, and has high construction requirements. Utility Model Content

Two rods connected to the load-bearing cable fixing component are located on both sides of the partition plate. The partition plate has a through hole 1 that mates with bolts, and each of the two rods has a through hole 2 corresponding to the through hole. The two rods are fixed to the partition plate by bolts.

[0011] Preferably, the load-bearing cable fixing component further includes at least one cable fixing block installed on the lower side of the cross plate, and the cable fixing block has a groove that mates with the load-bearing cable.

[0012] Preferably, the cable fixing block is fixedly connected to the underside of the cross plate by bolts.

Detailed Implementation

[0026] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0027] Example 1

[0028] like Figures 1 to 4 As shown in the figure, the present invention provides a three-cable mid-span triangular brace for flexible photovoltaic support. The triangular brace includes three fixedly connected rods 1 and a three-cable fixing assembly installed on the triangular brace. The three-cable fixing assembly includes a load-bearing cable fixing member 3 and two main cable fixing members 2.

[0029] In this embodiment, member 1 can be made of angle steel;

[0030] In this embodiment, the triangular brace is an inverted triangle, with the top (uppermost) member 1 being inclined. Two main cable fixing members 2 are installed on the member 1, and the load-bearing cable fixing members 3 are installed at the connection of the other two members 1.

[0031] The main cable fixing component 2 includes a U-shaped cable clamp 21 and a main cable fixing nut 22. The rod 1 has two through holes that mate with the U-shaped cable clamp 21. The U-shaped cable clamp 21 has threads that mate with the main cable fixing nut 22. During installation, the main cable is first passed through the U-shaped cable clamp 21, and then a part of the U-shaped cable clamp 21 is passed through the through hole and fixed by the main cable fixing nut 22. The main cable is confined within the area between the U-shaped cable clamp 21 and the rod 1.

[0032] The load-bearing cable fixing component 3 of this embodiment includes a horizontal plate 31 and a partition plate 32, and at least one cable fixing block 33 installed on the lower side of the horizontal plate 31. The horizontal plate 31 is perpendicular to the triangular brace. The cable fixing block 33 is provided with a limiting groove 34 that cooperates with the load-bearing cable. The cable fixing block 33 is fixed to the horizontal plate 31 by bolts 6.

[0033] In addition, the two rods 1 connected to the load-bearing cable fixing member 3 are located on both sides of the partition plate 32. The partition plate 32 is provided with a through hole 4 that cooperates with the bolt 6. The two rods 1 are provided with a through hole 5 corresponding to the through hole. The two rods 1 are fixed to the partition plate 32 by bolt 6.

[0034] The load-bearing cable fixing component 3 can fix the load-bearing cable (i.e., the third cable), which solves the problem of relative slippage along the cable direction when the triangular brace is subjected to eccentric force;

[0035] The triangular brace structure in this embodiment is more economical than the existing square pyramid support, with a significant cost advantage, and is easy to manufacture, as it can be made using conventional angle iron.

[0036] In addition, the weight of the triangular brace is lower than that of the square pyramid support, which greatly reduces the burden on the flexible photovoltaic support system and improves the overall stability of the flexible photovoltaic support.

[0037] Example 2

[0038] like Figure 5 As shown, this embodiment, based on the flexible photovoltaic support three-cable mid-span triangular brace of embodiment one, also includes a connecting component for connecting two adjacent triangular braces. The connecting component includes at least one connecting rod 7. This embodiment takes three connecting rods 7 as an example.

[0039] One of the connecting rods 7 connects to the load-bearing cable fixing parts 3 of two adjacent triangular supports. The other two connecting rods 7 are staggered, with one end connected to the connecting rod located on the upper side and the other end connected to the horizontal plate 31 or partition plate 32 of the load-bearing cable fixing part 3.

[0040] Specifically, two rods 1 connected to the load-bearing cable fixing member 3 are fixedly connected to another rod 1. Both ends of the other rod 1 are provided with mounting holes 8 for installing connecting rods 7. The load-bearing cable fixing member 3 is also provided with mounting holes 8 for installing connecting rods 7, so that two adjacent load-bearing cable fixing members 3 can be connected by connecting rods 7.

[0041] This connecting component allows two adjacent triangular supports to be connected, forming a more stable structure.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
