[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] like Figure 5 As shown, an embodiment of the present application discloses a flexible photovoltaic system wind-resistant support, including a base 10, a main rod unit, a first support rod unit and a second support rod unit.

[0054] Among them, the base 10 is made of sheet metal parts that are bent as a whole. Compared with the prior art in which the base 10 is formed by welding multiple parts, the integrated structure makes the base 10 have better strength, durability and stability, and the assembly is simpler, saving time and effort, and reducing the difficulty of assembly. The main rod unit includes two main rods 20 that are relatively inclined. The main rod 20 is a V-shaped structure as a whole and is made of a square tube that is bent as a whole. The two main rods 20 are detachably connected to the base 10 to form a quadrangular pyramid structure, and it is an inverted structure, and the quadrilateral bottom surface of the quadrangular pyramid structure is arranged upward. The main rod 20 is made of a square tube that is bent as a whole. Compared with the prior art in which multiple rods are welded, the integrated structure makes the main rod 20 have better strength and durability, and the assembly is simpler, saving time and effort, and reducing the difficulty of assembly. It should be noted that the main rod 20 and the base 10 can be connected by bolts and nuts, or other connection methods, and the detachable connection method is convenient for disassembly and assembly.

[0055] The first support rod unit includes two first support rods 30, which are made of square tubes that are bent into one piece. The one-piece structure makes the first support rods 30 have better strength and durability, and is easier to assemble. One of the first support rods 30 connects the first ends of the two main rods 20, and the other first support rod 30 connects the second ends of the two main rods 20. The first support rod 30 is detachably connected to the main rod 20, and can be connected by bolts and nuts, or by a clamp. The bolt and nut connection is preferred. The detachable connection method is convenient for disassembly and assembly, and is also convenient for transportation.

[0056] The second support rod unit includes two second support rods 40, which are square tubes, one of which is connected to both ends of one of the main rods 20, and the other is connected to both ends of the other main rod 20. The second support rod 40 is detachably connected to the main rod 20 and the first support rod 30, and can be connected by bolts and nuts or by a clamp, preferably by bolts and nuts.

[0057] The first support rod 30 is provided with a main cable connector 50 for connecting the main cable 100. The extension direction of the main cable 100 is parallel to the extension direction of the second support rod 40. Figure 2 As shown, the main cable 100 includes at least two parallel arrangements, and the photovoltaic assembly is arranged on the top of the main cable 100.

This arrangement can further enhance the wind resistance of the main cable 100. It should be noted that the material of the main rod 20, the first support rod 30 and the second support rod 40 is preferably carbon steel.

[0058] The flexible photovoltaic system wind-resistant support disclosed in the embodiment of the present application adopts a base 10, a main rod 20, a first support rod 30 and a second support rod 40 to form a quadrangular pyramid structure, which is arranged at the bottom of the photovoltaic module, and can enhance the stability and wind resistance of the flexible photovoltaic system, reduce the risk of hidden cracks and overturning of the photovoltaic module, and at the same time, the flexible photovoltaic system wind-resistant support can ensure the stable operation of the photovoltaic module array. The main rod 20, the first support rod 30 and the second support rod 40 are all connected in a detachable manner, which is convenient for disassembly and assembly, simple to assemble, and easy to transport. The base 10, the main rod 20 and the first support rod 30 are all integrated structures, and the integrated structure can improve the rigidity and durability of the structure, and can further enhance the stability of the flexible photovoltaic system wind-resistant support structure.

[0059] like Figure 4 and Figure 13-14 As shown, in some specific embodiments, the first support rod 30 is connected to the main rod 20 and the second support rod 40 through a rod connector 110. The rod connector 110 includes a sleeve portion 111 and an ear plate 112 connected to the sleeve portion 111. The sleeve portion 111 can be made of a square tube, and the ear plate 112 and the sleeve portion 111 can be connected by welding.

The arrangement of the rod connector 110 facilitates the connection of the first support rod 30 , the main rod 20 and the second support rod 40 , and makes assembly and disassembly more convenient.

[0060] Based on the above embodiments, Figure 4 As shown, the first support rod 30 includes a second middle support portion 32' and second end support portions 31' located at both ends of the second middle support portion 32'. The second end support portions 31' are arranged obliquely relative to the second middle support portion 32'.

In order to reduce the occurrence of stress concentration and avoid sharp angles, the bottom plate 11 and the rod connecting portion 12 adopt an arc surface transition. The main rod 20 and the rod connecting portion 12 are detachably connected to facilitate disassembly and assembly. In order to further enhance the stability of the structure of the base 10, in some specific embodiments, bending parts 14 are relatively arranged on both sides of the bottom plate 10 (here refers to the direction parallel to the extension direction of the second support rod 30).

[0063] In order to further enhance the wind resistance of the wind-resistant bracket of the flexible photovoltaic system, in some specific embodiments, a stabilizing cable connector 80 is provided on the bottom plate 11, and the stabilizing cable connector 80 is used to connect the stabilizing cable, and the two ends of the stabilizing cable are respectively connected to the end brackets, and the middle is sequentially connected to the adjacent wind-resistant brackets of the flexible photovoltaic system.

The main rod 20 and the rod connecting portion 12 are provided with corresponding mounting holes. In order to prevent the fastening bolt 60 from loosening, a bending connector 90 is provided between the fastening bolt 60 and the main rod 20. The bending connector 90 is coated on the surface of the main rod 20 to provide a buffering effect, so that the fastening bolt 60 can be more tightly fixed on the main rod 20 and the rod connecting portion 12, and is not easy to loosen. The setting of the bending connector 90 can also play a certain protective role on the main rod 20. In order to further enhance the firmness of the connection, a gasket is provided between the fastening bolt 60 and the bending connector 90.
