Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a wind-resistant triangular truss connection node for flexible photovoltaic supports. Background Technology

[0002] Conventional photovoltaic (PV) brackets are structural systems used to fix and support PV modules, designed to ensure the stable and reliable operation of solar panels. PV brackets are usually made of materials such as steel, aluminum alloy, or stainless steel, and have good corrosion resistance and wind pressure resistance, enabling them to adapt to different environmental conditions. According to the installation method, PV brackets can be divided into fixed brackets, flexible brackets, tracking brackets, etc. Among them, flexible brackets can use relatively flexible ropes to connect multiple PV modules to form a PV array, allowing for the installation of PV modules over a large area at a low cost.

[0003] Traditional photovoltaic support structures often deform or are damaged when faced with strong winds or other external forces due to inadequate structural design. This is especially true when installing large or heavy photovoltaic modules, where the stability of the support structure is crucial. If the support system is not stable enough, it may cause the entire photovoltaic power generation system to tilt, break, or even damage the equipment, thereby affecting the operating efficiency and safety of the entire photovoltaic power generation system.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-2An embodiment of this utility model provides a wind-resistant triangular truss connection node for a flexible photovoltaic support, comprising: a first U-shaped plate 1.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the outer wall of the first U-shaped plate 1 is symmetrically hinged with two first connecting rods 3 by bolts 9. The ends of the two first connecting rods 3 away from the first U-shaped plate 1 are each hinged with a second U-shaped plate 2 by bolts 9. The first U-shaped plate 1 is hinged to the two first connecting rods 3 by bolts 9 to form a triangular support structure. In addition, the outer wall of the first U-shaped plate 1 is hinged with a second connecting rod 6 by bolts 9. One end of the bolt 9 is threaded with a second nut 10. When multiple flexible photovoltaic bracket wind-resistant triangular truss connection nodes are installed, the second connecting rod 6 can be hinged to other nodes.

[0020] Among them, such as Figures 1-3 As shown, U-shaped rope clips 4 are threaded through both the first U-shaped plate 1 and the second U-shaped plate 2. Both ends of the U-shaped rope clips 4 are threaded with first nuts 8, which fix the U-shaped rope clips 4 to the first U-shaped plate 1 and the second U-shaped plate 2. The second U-shaped plate 2 has a supporting square tube 7 inside, and the U-shaped rope clips 4 on the second U-shaped plate 2 pass through the supporting square tube 7. The supporting square tube 7 inside the second U-shaped plate 2 ensures that the triangular structure between the first U-shaped plate 1 and the second U-shaped plate 2 is a fixed supporting structure, effectively preventing the triangular structure from deforming and enabling it to withstand external forces in different directions.

[0021] Furthermore, the photovoltaic module cable 12 is passed through the U-shaped rope clip 4 located on the second U-shaped plate 2, and the photovoltaic module 5 is installed on the photovoltaic module cable 12. The U-shaped rope clip 4 not only facilitates the connection between the photovoltaic module cable 12 and the photovoltaic module 5, but also facilitates splicing with other pillars or support nodes.

[0022] like Figure 2 and Figure 3 As shown, a limiting block 11 is welded to the outer wall of the U-shaped rope clip 4. The limiting block 11 is located at the top of the supporting square tube 7 and can limit the position of the U-shaped rope clip 4 on the supporting square tube 7.

[0023] Based on the above technical solution, the working steps of this solution are summarized as follows: In this utility model, the first U-shaped plate 1 is hinged to two first connecting rods 3 by bolts 9, and the far ends of the two first connecting rods 3 are hinged to the second U-shaped plate 2 to form a triangular support structure. Furthermore, the second U-shaped plate 2 is provided with a supporting square tube 7 inside. This structure ensures that the triangular structure between the first U-shaped plate 1 and the second U-shaped plate 2 is a fixed support structure, effectively preventing the deformation of the triangular structure. It can withstand external forces in different directions, achieve excellent wind resistance, and thus improve the wind resistance stability of the overall support.

[0024] In addition, U-shaped rope clips 4 are respectively inserted through the first U-shaped plate 1 and the second U-shaped plate 2. The U-shaped rope clips 4 not only facilitate the connection of photovoltaic module cable 12 and photovoltaic module 5, but also facilitate splicing with other pillars or support nodes, thus improving the expandability of the photovoltaic support.

[0025] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
