Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Figure 3 As shown, the middle portion of the bow rod 1-1 is used to connect with the load-bearing cable 3 of the photovoltaic module 2 of the flexible photovoltaic system, and the middle portion of the straight rod 1-2 is used to connect with the wind-resistant cable 5 of the ground anchor 4 of the flexible photovoltaic system;

[0040] The connecting rod 1-3 is connected between the middle portion of the bow rod 1-1 and the middle portion of the straight rod 1-2.

[0041] It should be noted that the structure of the bow rod 1-1 and the structure of the straight rod 1-2 can be referred to Figure 1 As shown, both ends of the bow rod 1-1 and both ends of the straight rod 1-2 are connected and fixed one by one through connecting components, and both ends of the connecting rod 1-3 are respectively connected and fixed with the middle part of the bow rod 1-1 and the middle part of the straight rod 1-2 through connecting components to form the bow-shaped wind-resistant bracket, and the bow-shaped wind-resistant bracket is located in the same plane, and does not appear three-dimensional like the existing wind-resistant bracket, so it can have certain wind-resistant performance. Of course, this bow-shaped wind-resistant bracket can be used in flexible photovoltaic systems with low requirements for wind resistance; and the bow-shaped wind-resistant bracket has a simple structure, low processing and manufacturing cost, and good economy. At the same time, the middle part of the bow rod 1-1 and the straight rod 1 -2 is connected with a connecting rod 1-3 between the middle parts, which can help improve the stability of the bow-shaped wind-resistant bracket; in addition, the bow-shaped wind-resistant bracket is small at the top and large at the bottom, that is, the upper part (bow rod 1-1) is small, and the lower part (straight rod 1-2) is large, and the upper part (bow rod 1-1) of the bow-shaped wind-resistant bracket is used to connect and fix with the load-bearing cable 3 of the photovoltaic component 2 of the flexible photovoltaic system, and plays the role of fixing the load-bearing cable 3 of the photovoltaic component 2, and the lower part (straight rod 1-2) is used to connect and fix with the wind-resistant cable 5 of the ground anchor 4 of the flexible photovoltaic system, and plays the role of tightening the lower part of the bow-shaped wind-resistant bracket. Of course, this also helps to improve the stability and wind resistance of the flexible photovoltaic system.

[0044] The first end of the first bending section 1-11 and the second end of the fourth bending section 1-15 are connected to the two ends of the straight rod 1-2 respectively.

[0057] like Figure 1 As shown, the second end of the connecting rod 1-3 and the middle part of the straight rod 1-2 can be connected by a second L-shaped connecting plate assembly 1-7; wherein, the second L-shaped connecting plate assembly 1-7 includes: a second connecting plate, a second L-shaped left connecting plate, a second L-shaped right connecting plate, a sixth bolt assembly, a seventh bolt assembly and an eighth bolt assembly; the second connecting plate can be set at the bottom of the middle part of the straight rod 1-2, the second L-shaped left connecting plate can be set between the top of the middle part of the straight rod 1-2 and the left part of the second end of the connecting rod 1-3, and the second L-shaped right connecting plate can be set at the straight rod 1-2 Between the top of the middle part and the right side part of the second end of the connecting rod 1-3, the sixth bolt assembly is used to connect the second connecting plate, the middle part of the straight rod 1-2 and the horizontal part of the second L-shaped left connecting plate in sequence, the seventh bolt assembly is used to connect the second connecting plate, the middle part of the straight rod 1-2 and the horizontal part of the second L-shaped right connecting plate in sequence, and the eighth bolt assembly is used to connect the vertical part of the second L-shaped left connecting plate, the second end of the connecting rod 1-3 and the vertical part of the second L-shaped right connecting plate in sequence; of course, the sixth bolt assembly, the seventh bolt assembly and the eighth bolt assembly can all include bolts and nuts.

[0058] That is, in the present bow-shaped wind-resistant support, adjacent rods are connected by bolt assemblies, or a connecting plate is first installed and then connected by bolt assemblies. This makes the structural connection of the bow-shaped wind-resistant support simpler, more stable, and more reliable, and also makes the assembly of the bow-shaped wind-resistant support easier, which to a certain extent helps to improve the wind resistance of the bow-shaped wind-resistant support. Of course, welding can also be used between the structural components of the bow-shaped wind-resistant support, which will not be described in detail here.

[0059] Furthermore, if Figure 3 As shown, the straight section 1-13 is provided with two load-bearing cable connection mechanisms, and is used to connect one to one with the two load-bearing cables 3 of the photovoltaic module 2;

[0060] Two wind-resistant cable connection mechanisms are provided in the middle part of the straight rod 1-2, and are used to be connected one by one with the first end hooks of the two wind-resistant cables 5 of the ground anchor 4; wherein, the two wind-resistant cable connection mechanisms are close to the two ends of the straight rod 1-2 one by one.

[0061] It should be noted that if Figure 1 As shown, the straight section 1-13 of the bow rod 1-1 is provided with two load-bearing cable connection mechanisms, that is, the middle straight section of the bow rod 1-1 is provided with two load-bearing cable connection mechanisms, which are used to connect and fix the two load-bearing cables 3 of the photovoltaic module 2 one by one, so as to fix the two load-bearing cables 3 of the photovoltaic module 2; Figure 1 As shown, two wind-resistant cable connection mechanisms are provided in the middle part of the straight rod 1-2, and are used to connect one by one with the first end hooks of the two wind-resistant cables 5 of the ground anchor 4 to tighten the straight rod 1-2 of the bow-shaped wind-resistant bracket; wherein, the two wind-resistant cable connection mechanisms are close to the two ends of the straight rod 1-2 one by one, that is, the distance between the two wind-resistant cable connection mechanisms is as large as possible, which facilitates the tightening of the entire straight rod 1-2 over a large span, and also makes the straight rod 1-2 more stable.

[0062] In this program, if Figure 1 As shown, the load-bearing cable connection mechanism includes a load-bearing cable clamping seat 1-8, which makes the connection and fixation of the load-bearing cable 3 more convenient; wherein, the load-bearing cable clamping seat 1-8 includes: a clamping seat, a U-shaped clamping strip and two nuts; the clamping seat can be set at the top of the straight section 1-13, the U-shaped clamping strip is used to pass through the clamping seat and the straight section 1-13 in sequence, and is used to cooperate with the clamping seat to clamp the load-bearing cable 3, and the two nuts are used to tighten the two parts of the U-shaped clamping strip passing through the bottom of the straight section 1-13 one by one, so that the U-shaped clamping strip clamps the load-bearing cable 3;

[0066] It should be noted that, in this embodiment, the first end of the first bent section 1-11 may be provided with the first connecting structure, or the first end of the straight rod 1-2 may be provided with the first connecting structure, or the first end of the first bent section 1-11 and the first end of the straight rod 1-2 may be provided with the first connecting structure. In this case, the connection between the first end of the support rod 6 and one side of the arched wind-resistant support can be made more secure.

[0067] Similarly, in this embodiment, the second end of the fourth bent section 1-15 may be provided with a second connecting structure, or the second end of the straight rod 1-2 may be provided with a second connecting structure, or the second end of the fourth bent section 1-15 and the second end of the straight rod 1-2 may both be provided with a second connecting structure.

This allows connections to be made between rows of photovoltaic modules in multiple rows. Of course, this also helps to connect the photovoltaic module array into a whole, enhance the stability and wind resistance of the flexible photovoltaic system, and ensure the stable operation of the photovoltaic module array. Of course, in the flexible photovoltaic system, the photovoltaic modules can be in a single row or in multiple rows, which makes it easier to form a photovoltaic module array; among them, Figure 4 As shown, there are three rows of photovoltaic panels.

[0069] Further, if Figure 1 As shown, the first connection structure includes a first connection through hole 1-111, which facilitates the connection of the first end of the support rod 6 of the adjacent rows of photovoltaic modules with the first connection through hole 1-111 of the first bent section 1-11 of the bow rod 1-1 through the bolt assembly, thereby making the connection between the first end of the support rod 6 of the adjacent rows of photovoltaic modules and one side of the bow-shaped wind-resistant support more convenient and stable;

[0070] The second connection structure includes a second connection through hole 1-151, which facilitates the connection of the second end of the support rod 6 of another adjacent row of photovoltaic modules with the second connection through hole 1-151 of the fourth bending section 1-15 of the bow rod 1-1 through the bolt assembly, thereby making the connection between the second end of the support rod 6 of another adjacent row of photovoltaic modules and the other side of the bow-shaped wind-resistant support more convenient and stable. Figure 3 As shown, the first end and the second end of the support rod 6 are both provided with connecting through holes. Figure 3As shown, the first end of the straight rod 1-2 may also be provided with a first connecting through hole 1-111, and the second end may also be provided with a second connecting through hole 1-151, so as to facilitate adjustment of the connection posture of the first end or the second end of the straight rod 1-2.

[0071] Furthermore, if Figure 1 As shown, the bow rod 1-1 is a bow-shaped square tube;

[0072] The straight rod 1-2 and the connecting rod 1-3 are both straight square tubes. This not only ensures the structural rigidity of the bow rod 1-1, the straight rod 1-2 and the connecting rod 1-3, but also facilitates the one-to-one overlap of the straight sections on both sides of the bow rod 1-1 with the two ends of the straight rod 1-2, thereby helping to improve the stability of the connection between the bow rod 1-1 and the straight rod 1-2.
