[0036] This embodiment provides a flexible photovoltaic support with relatively high structural stability, which can reduce the losses caused by uneven settlement of tailings slag, has a relatively high wind load resistance ability, improves the installation stability of photovoltaic modules, and moreover, has relatively low construction difficulty and construction cost.

[0037] Specifically, as Figures 1-3 shown, the flexible photovoltaic support includes a concrete spread foundation 100, flexible cables 200, and flexible support cables 300.

[0038] Among them, the concrete spread foundation 100 is in an X shape. End concrete columns 110 and a middle concrete column 120 are respectively provided at the four ends and the middle intersection of the concrete spread foundation 100. A flexible cable 200 is connected between the middle concrete column 120 and each end concrete column 110. A plurality of flexible support cables 300 are provided between every two adjacent flexible cables 200. All the flexible support cables 300 and all the flexible cables 200 form a support cable network, and the support cable network is used to fix the photovoltaic module 10.

[0039] The flexible photovoltaic support provided in this embodiment jointly forms a support fixing system through the end concrete columns 110, the middle concrete column 120, and the X-shaped concrete spread foundation 100. Compared with the ground piles or pipe piles in the prior art, this support fixing system has relatively high stability, has a relatively strong ability to resist deformation when uneven settlement occurs in the tailings slag, reduces the risk of deformation of the support cable network for fixing the photovoltaic module 10 above the support fixing system, and further reduces the risk of hidden cracks in the photovoltaic module 10, with relatively low accident losses.

[0040] Moreover, the concrete spread foundation 100, the end concrete columns 110, and the middle concrete column 120 are formed into an integral body by means of concrete pouring, further improving the structural stability, and having relatively low construction difficulty and construction cost. In addition, setting the concrete spread foundation 100 in an X shape can make full use of the site space and improve the space utilization rate.

[0041] A support cable network is formed by multiple flexible support cables 300 and multiple flexible cables 200, and the photovoltaic module 10 is fixed by the support cable network, which improves the vertical stiffness of the flexible photovoltaic module 10, reduces the vibration amplitude of the photovoltaic module 10 under wind load, thereby improving the wind resistance of the flexible photovoltaic support and extending the service life of the flexible photovoltaic support, with high practicability.

[0042] Optionally, continue to refer to Figure 1 , in this embodiment, the concrete spread foundation 100 is formed by symmetrically and cross-arranging a transverse concrete foundation 101 and a longitudinal concrete foundation 102, which is convenient for construction. The widths of the transverse concrete foundation 101 and the longitudinal concrete foundation 102 can be adjusted according to the bearing capacity of the foundation.

[0043] Optionally, both the flexible cable 200 and the flexible support cable 300 can be made of steel strands. Steel strands have the advantages of good flexibility, high tensile strength, good corrosion resistance and light texture.

[0044] Furthermore, continue to refer to Figure 1 , the support cable network is inclined. Specifically, the inclination angle of the support cable network can be adjusted by adjusting the heights of the end concrete columns 110 and the middle concrete columns 120, so that the photovoltaic module 10 can fully receive sunlight.

[0045] Furthermore, continue to refer to Figure 2 and Figure 3 , a middle cable fixing member 121 is embedded at the top of the middle concrete column 120, and an end cable fixing member 111 is embedded at the top of the end concrete column 110. One end of each flexible cable 200 is connected to the middle cable fixing member 121, and the other end is connected to the corresponding end cable fixing member 111. By embedding the middle cable fixing member 121 at the top of the middle concrete column 120 during the casting of the middle concrete column 120 to fix the middle cable fixing member 121, the construction is convenient, and the connection strength between the middle cable fixing member 121 and the middle concrete column 120 is relatively high, improving the reliability of the connection between the flexible cable 200 and the middle concrete column 120. By embedding the end cable fixing member 111 at the top of the end concrete column 110 during the casting of the end concrete column 110 to fix the end cable fixing member 111, the construction is convenient, and the connection strength between the end cable fixing member 111 and the end concrete column 110 is relatively high, improving the reliability of the connection between the flexible cable 200 and the end concrete column 110.

[0046] Preferably, continue to refer to Figure 2, in a possible embodiment, the end of the flexible cable 200 is connected to the end cable fixture 111 through a NUT clamp 400. The NUT clamp 400 can adjust the locking degree of the flexible cable 200. Therefore, the requirement for the processing precision of the length of the flexible cable 200 can be reduced. Moreover, after long-term use, the flexible cable 200 may become longer due to long-term tensile force. The NUT clamp 400 can also tighten the lengthened flexible cable 200 again without replacing the new flexible cable 200, reducing the maintenance difficulty and maintenance cost.

[0047] It should be noted that the structure of the NUT clamp 400 is prior art. Therefore, its specific structure will not be described in detail herein.

[0048] Preferably, referring further to Figure 3 , in another possible embodiment, the end of the flexible cable 200 can also be connected to the middle cable fixture 121 through a NUT clamp 400.

[0049] In this embodiment, the end of the flexible cable 200 is connected to the middle cable fixture 121 through a NUT clamp 400, and the end of the flexible cable 200 is also connected to the end cable fixture 111 through a NUT clamp 400. With such an arrangement, the adjustment range of the flexible cable 200 can be improved.

[0050] Furthermore, referring further to Figure 2 , in this embodiment, a plurality of support cable fixtures 700 are provided on the flexible cable 200. The flexible support cables 300 on both sides of the flexible cable 200 are arranged in one-to-one correspondence. One end of each pair of corresponding flexible support cables 300 is connected to the same support cable fixture 700 through a NUT clamp 400. The connection between the flexible support cable 300 and the flexible cable 200 is realized through the support cable fixture 700. The structure is simple, the connection reliability is relatively high, and one support cable fixture 700 can fix two flexible support cables 300, reducing the use of parts, which is beneficial to reducing the part cost and facilitating the assembly of the flexible photovoltaic bracket. Moreover, the flexible support cable 300 is connected to the support cable fixture 700 through a NUT clamp 400, which can realize the adjustment of the length of the flexible support cable 300. Therefore, the requirement for the processing precision of the length of the flexible support cable 300 can be reduced. In addition, after long-term use, the flexible support cable 300 may become longer due to long-term tensile force. The NUT clamp 400 can also tighten the lengthened flexible support cable 300 again without replacing the new flexible support cable 300, reducing the maintenance difficulty and maintenance cost. In addition, the structural stability of the flexible photovoltaic bracket can also be improved.

[0051] Furthermore, referring further to Figure 1, a plurality of flexible support cables 300 between adjacent two flexible cables 200 are arranged in parallel at intervals, and a plurality of photovoltaic modules 10 are laid on adjacent two flexible support cables 300. With such an arrangement, the photovoltaic modules 10 can be reliably fixed, the installation is relatively convenient, and the number of photovoltaic modules 10 that can be fixed is also relatively large.

[0053] Furthermore, as Figure 4 and Figure 5 shown, among a plurality of photovoltaic modules 10 laid on the same two flexible support cables 300, the sides of adjacent two photovoltaic modules 10 are connected to the flexible support cable 300 through the same middle clamp 500, and the sides of the two photovoltaic modules 10 at both ends are connected to the flexible support cable 300 through the edge clamps 600. Setting adjacent two photovoltaic modules 10 to share the middle clamp 500 can simplify the structure of the flexible photovoltaic support, is beneficial to reducing the part cost, and improving the assembly efficiency.

[0054] Furthermore, continue to refer to Figure 4 , in this embodiment, the middle clamp 500 includes a middle fixing block 510 arranged on the flexible support cable 300 and a middle pressing block 520 detachably connected to the middle fixing block 510. The middle pressing block 520 includes two symmetrically arranged middle pressing ears 521, and the two middle pressing ears 521 are used to press the connected two sides against the flexible support cable 300. When installing the middle clamp 500, first fix the middle fixing block 510 on the flexible support cable 300, then place the photovoltaic module 10, and finally make the two middle pressing ears 521 of the middle pressing block 520 correspond to the two sides to be fixed, and connect the middle pressing block 520 to the middle fixing block 510. The middle clamp 500 has a simple structure, is convenient to install, and has a better effect of fixing the photovoltaic module 10.

[0055] Optionally, the middle fixing block 510 can be connected to the middle pressing block 520 by means of bolt connection.

Moreover, the threaded connection method is also convenient for adjusting the pressing force of the middle pressing ears 521 on the photovoltaic module 10 to ensure the reliability of the middle clamp 500 in fixing the photovoltaic module 10.

[0056] Furthermore, continue to refer to Figure 5, in this embodiment, the edge fixture 600 includes an edge fixing block 610 disposed on the flexible support cable 300 and an edge pressing block 620 detachably connected to the edge fixing block 610. The edge pressing block 620 includes an edge pressing ear 621, and the edge pressing ear 621 is used to press the side edge at the end against the flexible support cable 300. When installing the edge fixture 600, first fix the edge fixing block 610 on the flexible support cable 300, then place the photovoltaic module 10, and finally align the edge pressing ear 621 of the edge pressing block 620 with the side edge to be fixed and connect the edge pressing block 620 to the edge fixing block 610. The edge fixture 600 has a simple structure, is convenient to install, and has a better effect of fixing the photovoltaic module 10.

[0057] Optionally, the edge fixing block 610 can be connected to the edge pressing block 620 by means of bolt connection. The bolt connection structure is simple, convenient for installation and disassembly, and has a relatively high connection strength. Moreover, the threaded connection method is also convenient for adjusting the pressing force of the edge pressing ear 621 on the photovoltaic module 10 to ensure the reliability of the edge fixture 600 in fixing the photovoltaic module 10.
