Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a flexible photovoltaic support. Background Technology

[0002] Currently, traditional photovoltaic (PV) supports are difficult to adapt to complex terrain environments, and flexible PV supports are being used more and more widely. However, because steel cables have a certain deformation capacity, in strong wind environments, the force of the wind causes wind vibration between the steel cables and the solar panels, causing the solar panels to sway. If the deformation is too large, it will greatly affect the safe and reliable operation of the flexible PV support and the stability of the PV modules, which greatly limits the use of flexible PV supports.

[0003] Therefore, it is necessary to provide a new flexible photovoltaic support system to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible photovoltaic support with a large span and strong wind resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible photovoltaic support structure includes:

[0007] A column assembly, comprising two side columns spaced apart along a first direction, the side columns being inclined along the first direction, and the distance between the upper ends of the two side columns being greater than the distance between the lower ends of the two side columns;

[0008] A beam is provided at the upper end of each of the aforementioned side columns;

[0009] An anchor cable assembly, comprising a first anchor cable and a second anchor cable, wherein one end of the first anchor cable and one end of the second anchor cable are symmetrically connected to the beam, and the other end of the first anchor cable and the other end of the second anchor cable are connected to the same fixed point, and the first anchor cable, the second anchor cable and the beam cooperate to form a triangular structure;

[0010] The cable includes two parallel main cables that connect adjacent beams and are used for fixed connection with photovoltaic modules.

[0011] As a further improvement of the present invention, the flexible photovoltaic support also includes a foundation, which is fixed to the ground and includes a first foundation and a second foundation. Two second foundations are arranged on both sides of the flexible photovoltaic support along the first direction, and multiple first foundations are arranged between two second foundations. The cable extends along the first direction, and the first anchor cable and the second anchor cable are connected to the same second foundation through a connecting structure.

[0012] As a further improvement of the present invention, the lower end of the side column is rotatably connected to the first foundation through a rotating support. The rotating support includes a first support and a second support. The first support is fixed to the lower end of the side column, and the second support is fixed to the upper end of the first foundation. The first support and the second support are rotatably connected by a rotating pin.

[0013] As a further improvement of this utility model, the connection structure includes a first U-bolt, a first limiting plate, a second U-bolt, a second limiting plate, and a lifting eye bolt. The lifting eye bolt is fixed to the upper surface of the second foundation. One end of the first anchor cable passes through the first limiting plate and is locked by a locking sleeve. One end of the second anchor cable passes through the second limiting plate and is locked by a locking sleeve. The first U-bolt passes through the lifting eye portion at the end of the lifting eye bolt and is fixedly connected to the first limiting plate. The second U-bolt passes through the lifting eye portion at the end of the lifting eye bolt and is fixedly connected to the second limiting plate.

[0014] As a further improvement of the present invention, the column assembly further includes a central column, which is disposed between the two side columns. The central column is perpendicular to the ground and connected to the first foundation. The beam on the central column is provided with a lifting ring, which is fixed above the beam. The two main cables are respectively threaded through the two lifting rings.

[0015] As a further improvement of the present invention, the cable also includes at least one wind-resistant cable located below the main cable. The wind-resistant cable connects the beams on the two side columns. The cross-section of the beam is circular or annular. One end of the wind-resistant cable is wrapped around the outer circumference of the beam and then fixed by fasteners.

[0016] As a further improvement of the present invention, the flexible optical support also includes a support frame, and a plurality of the support frames are spaced apart on the cable along a first direction. The support frame has at least four ends, and the number of the ends of the support frame connected to the main cable is not less than the number of the ends of the support frame connected to the wind-resistant cable.

[0017] As a further improvement of the present invention, the support frame includes a first end, a second end, a third end, and a fourth end.

[0018] As a further improvement of this utility model, the beam is inclinedly disposed at the upper end of the column assembly, and the two main cables are set at an angle to the horizontal plane, so as to make the photovoltaic module inclined.

[0019] As a further improvement of this utility model, the included angle between the side post and the main cable is equal to the included angle between the side post and the anchor cable assembly.

[0020] Compared to existing technologies, the advantages of this flexible photovoltaic support system are as follows: by tilting the end columns, the end columns simultaneously generate upward and lateral support forces, thereby improving the stability and wind resistance of the flexible photovoltaic support system and enabling it to adapt to large-span projects. V-shaped anchor cable assemblies are installed at both ends to connect to the beam, forming a stable triangular structure with the beam, further enhancing stability and wind resistance. This flexible photovoltaic support system can adapt to complex terrain, ensure the continuous and stable operation of photovoltaic projects, and has advantages such as large span, strong wind resistance, and low cost.

[0046] Please see Figures 1 to 22 As shown, this embodiment discloses a flexible photovoltaic support system, including a column assembly 2, a beam 3, and a cable 5. The beam 3 is disposed at the upper end of the column assembly 2, and the two ends of the cable 5 are connected to the beam 3 and used to support the photovoltaic module 100. In this embodiment, the flexible photovoltaic support system also includes a foundation 1, which is fixed to the ground, and the column assembly 2 is connected to the foundation 1. The foundation 1 can be a pile foundation structure fixed to the ground, such as a precast pile or a cast-in-place pile, and one end of the column assembly 2 is connected to the foundation 1; in other embodiments, the foundation 1 can be omitted, and one end of the column assembly 2 can be directly buried underground.

[0047] To facilitate the description of the embodiments of this utility model, a first direction and a second direction are used for auxiliary explanation. The first direction and the second direction are perpendicular to each other, wherein D1 in the figure represents the first direction and D2 represents the second direction.

[0048] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 16 and Figure 17 As shown, foundation 1 includes a first foundation 11 and a second foundation 12. Two second foundations 12 are positioned on both sides of the flexible photovoltaic support along a first direction, and multiple first foundations 11 are positioned between the two second foundations 12. The column assembly 2 includes two side columns 21 spaced apart along the first direction, with the side columns 21 positioned on the first foundation 11. The flexible photovoltaic support also includes an anchor cable assembly 4, which connects the two sides of the beam 3 on the side columns 21 to the second foundation 12. The anchor cable assembly 4 and the beam 3 cooperate to form a triangular structure to improve the stability and wind resistance of the flexible photovoltaic support.

[0049] Further, please refer to Figure 2 , Figure 7 and Figure 17 As shown, the anchor cable assembly 4 includes a first anchor cable 41 and a second anchor cable 42. One end of the first anchor cable 41 and one end of the second anchor cable 42 are symmetrically connected to the beam 3. The other ends of the first anchor cable 41 and the second anchor cable 42 are connected to the same second foundation 12. The first anchor cable 41, the second anchor cable 42, and the beam 3 together form a triangular structure. With this configuration, the first anchor cable 41 and the second anchor cable 42 share a single second foundation 12, saving on pile foundations and reducing costs. Simultaneously, a stable triangular structure is formed between the anchor cable assembly 4, the side column 21, and the ground, improving the overall stability of the flexible photovoltaic support structure. In other embodiments, the second foundation 12 can be omitted, and the other ends of the first anchor cable 41 and the second anchor cable 42 can be connected to the same fastener. This fastener can be directly installed on the ground; that is, the other ends of the first anchor cable 41 and the second anchor cable 42 are directly fixed to the ground by a fastener, such as a lifting eye bolt.

[0050] Please see Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the first anchor cable 41 and the second anchor cable 42 are connected to the same second foundation 12 via a connecting structure 43. Specifically, the connecting structure 43 includes a first U-bolt 431, a first limiting plate 432, a second U-bolt 433, a second limiting plate 434, and a lifting eye bolt 435. The lifting eye bolt 435 is fixed to the second foundation 12, and the lifting eye portion 4351 of the lifting eye bolt 435 is at least partially exposed on the upper surface of the second foundation 12. One end of the first anchor cable 41 passes through the first limiting plate 432 and is locked by the locking sleeve 436. One end of the second anchor cable 42 passes through the second limiting plate 434 and is locked by the locking sleeve 436. The first U-bolt 431 passes through the eye bolt 4351 and is fixedly connected to the first limiting plate 432. The second U-bolt 433 passes through the eye bolt 4351 and is fixedly connected to the second limiting plate 434. Both the first U-bolt 431 and the second U-bolt 433 pass through the eye bolt 435 at the end of the eye bolt 435. Furthermore, the first anchor cable 41 and the first U-bolt 431 are inserted from both sides of the first limiting plate 432, so that the first anchor cable 41 and the first U-bolt 431 exert opposite tensions on the first limiting plate 432. The second anchor cable 42 and the second U-bolt 433 are inserted from both sides of the second limiting plate 434, so that the second anchor cable 42 and the second U-bolt 433 exert opposite tensions on the second limiting plate 434. With this configuration, the first anchor cable 41 and the second anchor cable 42 are connected to the same second foundation 12 through the connecting structure 43, and the first anchor cable 41 and the second anchor cable 42 form a V-shaped structure. This connecting structure 43 is simple to connect and easy to install.

[0051] In other embodiments, only one anchor cable assembly 4 is provided. In this case, the two ends of the anchor cable assembly 4 are symmetrically connected to the beam 3, and the middle end of the anchor cable assembly 4 is connected to the second foundation 12. The anchor cable assembly 4 and the beam 3 cooperate to form a triangular structure.

[0052] Please see Figures 1 to 7 As shown, cable 5 extends along a first direction and includes two main cables 51 arranged parallel to each other along a second direction and a wind-resistant cable 52 arranged below the main cables 51. The main cables 51 connect to adjacent beams 3, and the wind-resistant cable 52 connects to the beams 3 on the two side columns 21. The main cables 51 are used for fixed connection with the photovoltaic module 100.

[0053] Please see Figure 2 , Figure 7 , Figure 10 and Figure 11As shown, the side columns 21 are inclined. The first foundation 11 is coaxially fixedly connected to the side columns 21, meaning the first foundation 11 connecting the side columns 21 is also inclined. Furthermore, the distance between the upper ends of the two side columns 21 of the flexible photovoltaic support is greater than the distance between the lower ends of the two side columns 21, and the side columns 21 are inclined upwards along a first direction towards both ends of the flexible photovoltaic support. With this configuration, the side columns 21 provide support to the flexible photovoltaic support from below, diagonally upwards, while simultaneously generating upward and outward forces at both ends, thereby improving the stability and wind resistance of the entire flexible photovoltaic support and adapting to large-span scenarios.

[0054] Furthermore, the angle between the side post 21 and the main cable 51 is the same as the angle between the side post 21 and the anchor cable assembly 4. (See also...) Figure 22 As shown, F1 is the tension force of the main cable 51 on the side column 21, F2 is the tension force of the anchor cable assembly 4 on the side column 21, F is the resultant force of F1 and F2, δ1 is the angle between the main cable 51 and the side column 21, and δ2 is the angle between the anchor cable assembly 4 and the side column 21. When δ1=δ2, the direction of the resultant force F coincides with the axis of the side column. That is, when δ1=δ2, the side column 21 is an axially compressed member and is not affected by horizontal shear force, which can realize the design of the side column 21 without horizontal shear force. Other flexible photovoltaic brackets have a design of inclined anchor cables and vertical columns at both ends, which have a large horizontal shear force, resulting in a large diameter of the pull-out pile and increasing the cost. The shear force-free design of this embodiment can avoid the risk of vertical column damage caused by the horizontal displacement of the foundation due to excessive horizontal force and reduce costs.

[0055] Please see Figure 1 , Figure 4 , Figure 6 , Figure 10 As shown, the support column assembly 2 also includes a central support column 22, positioned between the two side supports 21. The central support column 22 is perpendicular to the ground and connected to the first foundation 11, meaning the first foundation 11 connecting the central support column 22 is also vertically positioned. Further, the beam 3 on the central support column 22 is equipped with lifting rings 7, which are fixed above the beam 3. Two main cables 51 pass through the two lifting rings 7 respectively. This arrangement allows the flexible photovoltaic support to have a large span, and the middle of the main cables 51 is unrestrained and can slide freely in the first direction, reducing the torsion of the central support column 22 when the flexible photovoltaic support is exposed to wind, enhancing stability and saving materials. Specifically, the lifting ring 7 includes an annular portion 71 and a mounting portion 72. The mounting portion 72 is inserted into and fixed in a mounting groove on the upper surface of the beam 3, and the main cables 51 pass through the annular portion 71.

[0056] In this embodiment, a beam 3 is supported by a side column 21 or a central column 22. The central support of the beam 3 is located at the upper end of the side column 21 or the central column 22. This reduces the number of column assemblies 2 compared to the existing structure where a column is placed at each end of the beam 3, simplifying the structure of the flexible photovoltaic support and lowering production and installation costs. In this embodiment, the column assembly 2 is a circular tube column, and the beam 3 is a circular tube steel beam. The column assembly 2 and the beam 3 are integrally welded, which not only provides good stress distribution but also saves materials. Furthermore, the inclined placement of the side column 21 ensures a more reasonable and stable stress distribution for large-span projects. To save costs, the beam 3 is a hollow circular tube steel beam structure, meaning the cross-section of the beam 3 is circular. In other embodiments, to increase the support strength of the beam 3, it can also be a solid structure, meaning the cross-section of the beam 3 is circular. Additionally, in other embodiments, the column assembly 2 and / or the beam 3 can be made of H-beams, C-beams, or L-beams, etc.

[0057] Furthermore, beam 3 is inclinedly positioned at the upper end of column assembly 2, and the two main cables 51 are angled to the horizontal plane to tilt the photovoltaic module 100. This arrangement allows the photovoltaic module 100 to better adapt to the incident angle of sunlight, thereby achieving greater power generation.

[0058] Please see Figures 10 to 12 As shown, the lower end of the side column 21 is rotatably connected to the first foundation 11 via a rotating support 14. Specifically, the rotating support 14 includes a first support 141 and a second support 142. The first support 141 is fixed to the lower end of the side column 21, and the second support 142 is fixed to the upper end of the first foundation 11. The first support 141 and the second support 142 are rotatably connected, which can be achieved by a rotating pin (not shown in the figure), so that the side column 21 and the first foundation 11 are rotatably connected. Furthermore, the side column 21 can rotate vertically relative to the first foundation 11. With this configuration, setting the side column 21 and the first foundation 11 as a rotatable connection, the side column 21 is not subject to bending, improving its service life. Moreover, the upper part of the side column 21 is tightened by the cable 5 and the anchor cable assembly 4, which does not affect the structural stability.

[0059] Please see Figure 1 , Figure 3As shown, the flexible photovoltaic support in this embodiment also includes a support frame 6, which is connected to the cable 5. Multiple support frames 6 are spaced apart along a first direction on the cable 5, and each support frame 6 has at least two triangular structures connecting two main cables 51 and one wind-resistant cable 52. Specifically, the support frame 6 is a triangular pyramid, square pyramid, pentagonal pyramid, or other polygonal pyramid structure; in some embodiments, when the number of wind-resistant cables 52 is two, the support frame 6 can be set as a trapezoidal structure; in this embodiment, the support frame 6 is a triangular pyramid. With this configuration, the support frame 6 adopts a spatially stable triangular pyramid form, which is a stable structure in all directions of space, improving the stability and wind resistance of the cable 5, effectively supporting the cable 5 and the photovoltaic module 100, preventing the photovoltaic module 100 from sagging and twisting, further improving the overall structural stability.

[0060] Please see Figure 3 , Figure 13 , Figure 14 , Figure 15 As shown, the overall frame of the support frame 6 is composed of multiple support rods 60, having at least four ends. Each cable 5 is connected to at least one end, and the number of ends connected to the main cable 51 is not less than the number of ends connected to the wind-resistant cable 52. In this embodiment, the support frame 6 includes a first end 61, a second end 62, a third end 63, and a fourth end 64, with support rods 60 connected to each pair of the four ends. Specifically, the first end 61 is connected to the wind-resistant cable 52, the second end 62 and the third end 63 are connected to one of the main cables 51, and the fourth end 64 is connected to another main cable 51. That is, the entire support frame 6 is in the shape of an inverted triangular cone on the cable 5, with two triangular structures connecting the two main cables 51 and one wind-resistant cable 52, one triangular structure connecting the two main cables 51, and one triangular structure connecting one of the main cables 51 and the wind-resistant cable 52. The cooperation between the support frame 6 and the cable 5 can improve the overall structural stability. At the same time, the multiple connections between the support frame 6 and the cable 5 make the connection between the two more stable, and the support frame 6 is not easy to sway on the cable 5.

[0061] Please see Figure 20 and Figure 21 As shown, slots 603 are provided at both ends of the support rod 60 for mounting the connecting part 601. The thickness of the slot 603 is adapted to the thickness of the connecting part 601, and the connecting part 601 is partially inserted into the slot 603, which can be further strengthened by bonding or welding. In this way, by separating the support rod 60 and the connecting part 601, the support frame 6 can be assembled more flexibly.

[0062] Furthermore, the support rod 60 is connected to the ends of the main cable 51, namely the second end 62, the third end 63, and the fourth end 64. The lifting ring 7 is sequentially threaded through multiple connecting parts 601 at the same end from top to bottom, and the annular part 71 of the lifting ring 7 is positioned above the mounting part 72. The support rod 60 is connected to the end of the wind-resistant cable 52, namely the first end 61. The lifting ring 7 is sequentially threaded through multiple connecting parts 601 from bottom to top, and the annular part 71 of the lifting ring 7 is positioned below the mounting part 72. In this way, the support frame 6 is set up as a whole between the main cable 51 and the wind-resistant cable 52, so that the support frame 6 can better cooperate with the stabilizing cable 5 to form a stable structure to resist wind force.

[0063] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 17 and Figure 19 As shown, the ends of the main cable 51 and the wind-resistant cable 52 are both fixed to the beam 3 on the side column 21, and both the main cable 51 and the wind-resistant cable 52 have tension towards their respective ends. Specifically, the end of the main cable 51 is fixed to the beam 3 on the side column 21 by an anchor 53. The two ends of the main cable 51 pass through the two beams 3 respectively along the first direction. The anchor 53 is set on the side of the two beams 3 that is far away from each other. The anchor 53 includes a locking sleeve 531 and a fixing block 532. One side of the fixing block 532 fits in close contact with a part of the surface of the beam 3, that is, the arc surface. The locking sleeve 531 locks and fixes the cable 5 and abuts against the other side of the fixing block 532. The main cable 51 is at least partially exposed on the side of the locking sleeve 531 that is far away from the fixing block 532. The anchor 53 is used to fix the end of the main cable 51, which facilitates the application and maintenance of outward tension at both ends of the main cable 51 during installation. This ensures that the main cable 51 is tensioned and that each end of the main cable 51 has tension, thereby improving the stability of the main cable 51 and its support for the photovoltaic module 100. The beam 3 has a circular or annular cross-section. The two ends of the wind-resistant cable 52 are respectively wrapped around the outer circumference of the beam 3 on the side column 21, folded over, and fixed with fasteners. This arrangement ensures that the force exerted by the wind-resistant cable 52 on the beam 3 is uniform, improving the stability of the beam 3. Specifically, the fasteners can be the anchor 53 or other known cable-locking structures, as long as they can achieve the tensioning and fixing of the wind-resistant cable 52, which will not be elaborated further here.

[0064] Please see Figure 11 , Figure 17 and Figure 19As shown, the upper ends of the first anchor cable 41 and the second anchor cable 42 are fixed to the beam 3 on the side column 21 by anchor 53. The first anchor cable 41 and the second anchor cable 42 pass through the beam 3 along their respective extension directions. The anchor 53 is located on the side where the upper ends of the first anchor cable 41 and the second anchor cable 42 protrude from the beam 3. The upper ends of the first anchor cable 41 and the second anchor cable 42 are each fitted with a fixing block 532 and a locking sleeve 531. One side of the fixing block 532 fits snugly against a portion of the surface of the beam 3. The locking sleeve 531 locks the ends of the first anchor cable 41 and the second anchor cable 42 and abuts against the other side of the fixing block 532. At least part of the first anchor cable 41 and the second anchor cable 42 are exposed on the side of the locking sleeve 531 away from the fixing block 532. The anchor 53 is used to fix and connect the anchor cable assembly 4 to the beam 3, so that the anchor cable assembly 4 has tension, thereby generating a downward stable tension on the beam 3, strengthening the stable support for the beam 3 and the side column 21, and thus improving the stability of the cable 5.

[0065] This embodiment also discloses a flexible photovoltaic array, including at least two rows of flexible photovoltaic supports as described above.

[0066] Please see Figure 6 , Figure 7 , Figure 16 and Figure 17 As shown, in this embodiment of the flexible photovoltaic array, a first wind-resistant component is provided between two adjacent side columns 21 and / or central columns 22 in the second direction to enhance the wind resistance of the column assembly 2 and the flexible photovoltaic array as a whole. The first wind-resistant component includes a crossbar 23 and a stay cable 24. The crossbar 23 is fixedly connected to two side columns 21 or two central columns 22 of adjacent rows of flexible photovoltaic supports. The two ends of the stay cable 24 are respectively connected to the two side columns 21 or two central columns 22, and the two stay cables 24 are arranged in a crisscross pattern. Specifically, the two ends of the crossbar 23 are fixedly connected to the upper parts of the two side columns 21 or two central columns 22, one end of the stay cable 24 is connected to the upper part of one side column 21 or central column 22, and the other end is connected to the lower part of the other side column 21 or central column 22. The upper and lower parts of the side columns 21 and the middle columns 22 are fixedly equipped with clamp connectors 25. The clamp connectors 25 have mounting holes 251. The crossbars 23 and the inclined cables 24 are connected to the two side columns 21 or the two middle columns 22 through the mounting holes 251. This arrangement enhances the wind resistance and stability of the two adjacent rows of flexible photovoltaic supports.

[0067] Please see Figure 6 , Figure 9 and Figure 18As shown, in this embodiment of the flexible photovoltaic array, a second wind-resistant component is provided between two adjacent support frames 6 in the second direction to enhance the wind resistance between the support frames 6 of different rows of flexible photovoltaic supports and the flexible photovoltaic array as a whole. The second wind-resistant component includes a tie rod 65 and a first cable 66. One end of each tie rod 65 is connected to the first end 61 of one of the support frames 6, and the other ends of each tie rod 65 are connected to the second end 62 and the third end 63 of the other support frame 6, respectively. The first cable 66 connects the first ends 61 of the two support frames 6. With this arrangement, two adjacent support frames 6 in the second direction are connected into a whole by the second wind-resistant component, and multiple support frames 6 are sequentially connected to each other, which can jointly resist wind force and improve the wind resistance of the entire flexible photovoltaic array in the second direction.

[0068] Furthermore, the multiple rows of flexible photovoltaic brackets of the flexible photovoltaic array are connected by a first cable 66 in the second direction. The two ends of the first cable 66 are fixed to the first end 61 of the support frame 6 of the outer two rows of flexible photovoltaic brackets.

[0069] Please see Figure 6 , Figure 8 , Figure 10 , Figure 13 , Figure 14 and Figure 15 As shown, the two rows of flexible photovoltaic supports on the outer side are equipped with a third wind-resistant component to further enhance the overall stability and wind resistance of the flexible photovoltaic array. The third wind-resistant component includes a second cable assembly and a third cable assembly. One end of each of the second and third cable assemblies is connected to the same support frame 6, and the other ends are each connected to a fixed point. The second and third cable assemblies are symmetrically arranged relative to the support frame 6, and they are arranged in an inverted V-shape in the vertical direction, meaning the distance between the ends of the second and third cable assemblies connected to the support frame 6 is less than the distance between the other ends of the second and third cable assemblies connected to the two third bases 13. Furthermore, the base 1 also includes multiple third bases 13 located on both sides of the flexible photovoltaic array in the second direction, used to connect the lower ends of the second and third cable assemblies, thus serving as fixing points. With this configuration, the support frame 6 and the second wind-resistant component are indirectly connected and fixed to the ground along the second direction, and the second cable component, the third cable component and the ground form a stable triangular structure, which further improves the wind resistance of the entire flexible photovoltaic array in the second direction.

[0070] Specifically, please refer to Figure 8 , Figure 14 and Figure 15As shown, in this embodiment, the second cable assembly includes two second cables 67, and the third cable assembly includes two third cables 68. On one of the outermost rows of flexible photovoltaic supports, the upper ends of the two second cables 67 are respectively connected to the first end 61 and the second end 62 of the support frame 6, and the lower ends of the two second cables 67 are connected to a third foundation 13. The two second cables 67 are arranged in a V-shape in the vertical direction. The upper ends of the two third cables 68 are respectively connected to the first end 61 and the third end 63 of the support frame 6, and the lower ends of the two third cables 68 are connected to another third foundation 13. The two third cables 68 are arranged in a V-shape in the vertical direction. On another row of flexible photovoltaic supports located on the outer side, the upper ends of two second cables 67 are connected to the first end 61 and the fourth end 64 of the support frame 6, respectively, and the lower ends of the two second cables 67 are connected to a third foundation 13. The two second cables 67 are arranged in a V-shape in the vertical direction. The upper ends of two third cables 68 are connected to the first end 61 and the fourth end 64 of the support frame 6, respectively, and the lower ends of the two third cables 68 are connected to another third foundation 13. The two third cables 68 are also arranged in a V-shape in the vertical direction. In this way, the second cables 67 and the third cables 68 are symmetrically arranged, forming a stable triangular structure between the two second cables 67 and the support frame 6, and also forming a stable triangular structure between the two third cables 68 and the support frame 6. Both the upper and lower ends of the support frame 6 are connected to the ground, which can resist strong winds and provide effective support for the support frame 6 and the photovoltaic module 100, thereby enhancing the stability and wind resistance of the flexible photovoltaic array.

[0071] In this embodiment, the flexible photovoltaic array uses a first wind-resistant component, a second wind-resistant component, and a third wind-resistant component to form an overall force-bearing system with multiple rows of flexible photovoltaic supports, thereby enhancing the overall integrity of the system and better resisting the impact of wind loads on the photovoltaic modules 100. By tilting the side columns 21 and fixing both ends of the cable 5 to the side columns 21, the side columns 21 provide lateral (i.e., first direction) support for the cable 5, giving the cable 5 better lateral wind resistance. V-shaped anchor cables connect the beam 3 on the side columns 21 to the ground, forming a stable triangular structure and enhancing the stability of the beam 3, further improving the lateral wind resistance of the cable 5. The central column 22 is vertically positioned, and a hanging ring 7 passes through the middle of the main cable 51 above the central column 22, allowing the main cable 51 to be unrestrained laterally and reducing the stress on the central column 22. Adjacent column assemblies 2 in the longitudinal direction (i.e., second direction) are connected by a first wind-resistant assembly to improve the stability and wind resistance of the column assembly 2. Triangular pyramidal support frames 6 are spaced apart on the cable 5, and the support frames 6 are connected together in the longitudinal direction by a second wind-resistant assembly, with both ends connected to the ground by a third wind-resistant assembly, providing longitudinal support for the cable 5 and giving the cable 5 better longitudinal wind resistance. The entire flexible photovoltaic array is connected into a mesh-like wind-resistant system, which provides high stability and wind resistance to ensure the continuous and stable operation of the photovoltaic project.

[0072] In summary, compared with existing technologies, the flexible photovoltaic support system of this invention has the following advantages: By tilting the side columns 21 at both ends, the side columns 21 simultaneously generate upward and lateral supporting forces, thereby improving the stability and wind resistance of the flexible photovoltaic support system and enabling it to adapt to large-span projects. V-shaped anchor cable assemblies 4 are installed at both ends to connect to the beam 3, forming a stable triangular structure with the beam 3, further enhancing stability and wind resistance. This flexible photovoltaic support system can adapt to complex terrain, ensure the continuous and stable operation of photovoltaic projects, and has advantages such as large span, strong wind resistance, and low cost.
