Description

Technical Field

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

[0002] Flexible photovoltaic (PV) mounting systems are systems used to install photovoltaic (PV) panels. Compared to traditional rigid PV mounting systems, flexible PV mounting systems are made of support frames and prestressed load-bearing steel cables, making them lighter, easier to carry, and easier to install. Flexible PV mounting systems are typically made of weather-resistant materials, allowing them to be used in various environmental conditions, and possess excellent corrosion resistance and UV resistance. Currently, in practical applications, flexible PV mounting systems are usually used in array configurations. After the solar panels are fixed in place, the steel cables have a certain deformation capacity. In strong winds, wind vibration can occur between the cables and the solar panels, causing the solar panels to sway. Excessive deformation can significantly affect the safe and reliable operation of the flexible PV mounting system and the stability of the PV modules, greatly limiting the use of flexible PV mounting systems.

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

One end of the first cable assembly and the second cable assembly are connected to the same support frame of the first or last row of flexible photovoltaic supports. The other ends of the first cable assembly and the second cable assembly are respectively connected to a fixed point. The first cable assembly and the second cable assembly are arranged in an inverted V shape in the vertical direction.

[0007] As a further improvement of the present invention, the first cable assembly includes two first cables. One end of the two first cables is connected to different endpoints of the support frame and is respectively connected to the main cable and the wind-resistant cable of the flexible photovoltaic bracket. The other end of the two first cables is connected to the same fixed point. The two first cables are arranged in a V-shape in the vertical direction.

[0008] As a further improvement of the present invention, the second cable assembly includes two second cables. One end of the two second cables is connected to different endpoints of the support frame and is respectively connected to the main cable and the wind-resistant cable of the flexible photovoltaic bracket. The other end of the two second cables is connected to the same fixed point. The two second cables are arranged in a V-shape in the vertical direction.

[0009] As a further improvement of the present invention, the first cable assembly and the second cable assembly are symmetrically arranged relative to the support frame, and the distance between the first cable assembly and the second cable assembly connected to one end of the support frame is less than the distance between the first cable assembly and the second cable assembly connected to the other end of the fixed point.

[0010] As a further improvement of the present invention, the first wind-resistant component includes a first tie rod, the two ends of the first tie rod are respectively connected to the corresponding support frame of the adjacent row of flexible photovoltaic brackets, and one end of the first tie rod is connected to the main cable of a flexible photovoltaic bracket, and the other end of the first tie rod is connected to the wind-resistant cable of another adjacent flexible photovoltaic bracket.

[0011] As a further improvement of the present invention, the number of the first tie rods is two, the support frame is a pyramidal structure and has at least four ends, one end of the two first tie rods is connected to the end of the support frame of the flexible photovoltaic bracket that is connected to the wind-resistant cable, and the other end of the two first tie rods is respectively connected to different ends of the support frame of adjacent rows of flexible photovoltaic brackets that are connected to the same main cable.

[0012] As a further improvement of the present invention, the support frame is a triangular pyramid structure, and the ends include a first end, a second end, a third end, and a fourth end. The first end is connected to the wind-resistant cable, the second end and the third end are connected to one of the main cables, and the fourth end is connected to the other main cable. Each pair of the first end, the second end, the third end, and the fourth end is connected to a support rod. One end of each of the two first tie rods is connected to the first end of one of the support frames, and the other ends of the two first tie rods are respectively connected to the second end and the third end of the adjacent support frames.

[0013] As a further improvement of the present invention, the first wind-resistant component further includes a second tie rod, the two ends of which are respectively connected to the corresponding support frame of the adjacent row of flexible photovoltaic brackets, one end of the second tie rod is connected to the fourth end of one of the support frames, the other end is connected to the first end of the adjacent support frame, and the second tie rod is located between two first tie rods;

[0014] The first wind-resistant component also includes a third cable, which connects the wind-resistant cables of the adjacent row of flexible photovoltaic supports and connects the first ends of the two support frames of the adjacent row of flexible photovoltaic supports.

[0015] As a further improvement of the present invention, the flexible photovoltaic array further includes a third wind-resistant component, which includes a crossbar and a stay cable. The crossbar is fixedly connected to two column components of the adjacent row of flexible photovoltaic supports, and the two ends of the stay cable are respectively connected to the two column components. The two stay cables are arranged in a cross configuration.

[0016] As a further improvement of the present invention, each of the flexible photovoltaic supports includes a side column and a beam. The beam is located at the upper end of the side column, and 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.

[0017] Compared to existing technologies, the advantages of this flexible photovoltaic array are as follows: The flexible photovoltaic array, through the first and second wind-resistant components, forms an integrated force-bearing system with multiple rows of flexible photovoltaic supports, enhancing the overall system's integrity and better resisting the impact of wind loads on the photovoltaic modules. The support frame connects the main cable and the wind-resistant cable, reducing the likelihood of photovoltaic module distortion and improving overall structural stability and wind resistance. The support frames of adjacent rows of flexible photovoltaic supports are connected by the first wind-resistant component, while the support frames of the first and last rows are connected to a fixed point through the second wind-resistant component, further enhancing wind resistance.

[0044] It should be understood that the terms "first," "second," and similar words used in the specification and claims of this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish the features. Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "before," "after," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation.

In this utility model, the word "several" means two or more.

[0045] Please see Figures 1 to 24 As shown, this embodiment discloses a flexible photovoltaic support, including a column assembly 2, a beam 3, and a cable 5. A foundation 1 is fixed to the ground, the lower end of the column assembly 2 is fixed to the foundation 1, the beam 3 is disposed at the upper end of the column assembly 2, and the cable 5 is connected to the beam 3 at both ends and used to support the photovoltaic module 100. In this embodiment, 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 fixed 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.

[0046] 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.

[0047] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the foundation 1 includes a first foundation 11 and a second foundation 12. The two second foundations 12 are located on both sides of the flexible photovoltaic support along the first direction, and multiple first foundations 11 are located between the two second foundations 12. The column assembly 2 is fixed to the first foundation 11 and includes two side columns 21. The flexible photovoltaic support also includes an anchor cable assembly 4, which connects the two ends 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.

[0048] Further, please refer to Figure 2 , Figure 6 and Figure 15As 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 fixing member. This fixing member can be directly installed on the ground, meaning the other ends of the first anchor cable 41 and the second anchor cable 42 are directly fixed to the ground by a fixing member.

[0049] In other embodiments, the anchor cable assembly 4 is provided with only one anchor cable. 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.

[0050] Please see Figures 1 to 6 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.

[0051] Please see Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the side columns 21 are inclined, and the first foundation 11 is coaxially and 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.

[0052] 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 24As 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.

[0053] Please see Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 23 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 coaxially fixed 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.

[0054] 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 uses 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.

[0055] Please see Figure 1 , Figure 3 As 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.

[0056] Please see Figure 3 , Figure 11 , Figure 12 , Figure 13 , Figure 16 and Figure 23 As shown, the overall frame of the support frame 6 is composed of multiple support rods 60, having at least four ends. Each main cable 51 and wind-resistant cable 52 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. Each of the four ends is connected to a support rod 60 in pairs and is respectively set to the cable 5 via a lifting ring 7. The two ends of the support rod 60 are provided with connecting portions 601, and the connecting portions 601 are provided with through holes 602. The through holes 602 of multiple connecting portions 601 located at the same end are axially aligned. The mounting portions 72 of the lifting rings 7 pass through these through holes 602 in sequence, and the corresponding cables 5 pass through the annular portions 71 of the lifting rings 7. 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.

[0057] Please see Figure 16 and Figure 21As 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.

[0058] 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 cable 5 to form a stable structure to resist wind force.

[0059] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 15 and Figure 22 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.

[0060] Please see Figure 10 , Figure 15 and Figure 22As 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 the 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.

[0061] This embodiment also discloses a flexible photovoltaic array, including at least two rows of flexible photovoltaic supports as described above, a first wind-resistant component, and a second wind-resistant component. The corresponding support frames 6 of adjacent rows of flexible photovoltaic supports are connected via the first wind-resistant component, and the support frames 6 of the first and last rows of flexible photovoltaic supports are respectively connected to different fixed points via the second wind-resistant component. This arrangement forms a unified force-bearing system across multiple rows of flexible photovoltaic supports, better resisting the impact of wind loads on the photovoltaic modules 100 and improving wind resistance. The fixed points can be pile foundations on the ground or the ground itself; that is, the second wind-resistant component can be directly fixed to the ground or fixed to the pile foundations on the ground using connectors such as eye bolts and U-bolts.

[0062] Please see Figure 5 , Figure 8 and Figure 17 As shown, in this embodiment of the flexible photovoltaic array, a first 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 photovoltaic supports and the flexible photovoltaic array as a whole. The first wind-resistant component includes a first tie rod 65 and a third cable 69. The two ends of the first tie rod 65 are respectively connected to the corresponding support frames 6 of adjacent rows of flexible photovoltaic supports, and one end of the first tie rod 65 is connected to the main cable 51 of a flexible photovoltaic support, and the other end of the first tie rod 65 is connected to the wind-resistant cable 52 of another adjacent flexible photovoltaic support. There are two first tie rods 65. The support frame 6 has at least four ends. One end of the two first tie rods 65 is connected to the end of the support frame 6 of a flexible photovoltaic support that is connected to the wind-resistant cable 52, and the other ends of the two first tie rods 65 are respectively connected to different ends of the support frames 6 of adjacent rows of flexible photovoltaic supports that are connected to the same main cable 51.

[0063] Specifically, in this embodiment, one end of each of the two first tie rods 65 is connected to the first end 61 of one of the support frames 6, and the other ends of the two first tie rods 65 are respectively connected to the second end 62 and the third end 63 of another support frame 6. The third cable 69 is connected to the wind-resistant cable 52 of the adjacent row of flexible photovoltaic supports and is connected to the first end 61 of the two support frames 6 of the adjacent row of flexible photovoltaic supports. Specifically, each end of the first tie rod 65 is provided with a connecting part 601, which is fixedly connected to the connecting part 601 of the end of the corresponding support frame 6. The connecting part 601 of the first tie rod 65 and the multiple connecting parts 601 of the corresponding end of the support frame 6 are fixed by a hanging ring 7. The two ends of the third cable 69 are connected by the hanging rings 7 of the first end 61 of the two support frames 6. With this configuration, two adjacent support frames 6 along the second direction are connected into a whole by the first wind-resistant component, and then multiple support frames 6 are connected to each other in sequence, which can jointly resist wind force and improve the wind resistance of the entire flexible photovoltaic array in the second direction.

[0064] Furthermore, the multiple support frames 6 corresponding to the multi-row photovoltaic brackets of the flexible photovoltaic array in the second direction are connected by a third cable 69. The third cable 69 passes through the lifting rings 7 at the first end 61 of the multiple support frames 6 in sequence, and both ends of the third cable 69 are fixed to the lifting rings 7 at the first end 61 of the support frames 6 of the outer two rows of photovoltaic brackets. In this embodiment, the third cable 69 is folded and fixed after passing through the lifting rings 7. The two ends of the first pull rod 65 are the same as those of the support rod 60, and slots 603 are provided for installing the connecting part 601. The connecting part 601 is partially inserted into the slot 603 of the first pull rod 65, and can be further strengthened by bonding or welding. The first pull rod 65 and the connecting part 601 are set separately, so that the first pull rod 65 can be used to connect the two support frames 6 more flexibly.

[0065] Please see Figures 18 to 20 As shown, in another embodiment, the flexible photovoltaic array further includes a second tie rod 66. Both ends of the second tie rod 66 are connected to the corresponding support frames 6 of adjacent rows of flexible photovoltaic supports. One end of the second tie rod 66 is connected to the main cable 51 of one flexible photovoltaic support, and the other end is connected to the wind-resistant cable 52 of another adjacent flexible photovoltaic support. There is one second tie rod 66. One end of the second tie rod 66 is connected to the fourth end 64 of one support frame 6, and the other end is connected to the first end 61 of another support frame 6. The second tie rod 66 is located between two first tie rods 65. This arrangement further enhances the connection stability of adjacent rows of flexible photovoltaic supports, thereby improving wind resistance.

[0066] Please see Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, the two rows of flexible photovoltaic supports on the outer side are equipped with second wind-resistant components to further enhance the overall stability and wind resistance of the flexible photovoltaic array. The second wind-resistant components include a first cable assembly and a second cable assembly. One end of each cable assembly is connected to the same support frame 6, and the other ends are each connected to a fixed point. The first and second cable assemblies are symmetrically arranged relative to the support frame 6, and they form an inverted V-shape in the vertical direction, meaning the distance between the ends of the first and second cable assemblies connected to the support frame 6 is less than the distance between the other ends connected to the fixed points. Furthermore, the foundation 1 also includes multiple third foundations 13 located on both sides of the flexible photovoltaic array in the second direction, connecting the lower ends of the first and second cable assemblies, thus acting as fixed points. This arrangement indirectly connects and fixes the support frame 6 and the first wind-resistant components to the ground along the second direction, and the first and second cable assemblies form a stable triangular structure with the ground, further improving the wind resistance of the entire flexible photovoltaic array in the second direction.

[0067] Specifically, please refer to Figure 7 , Figure 12 and Figure 13As shown, in this embodiment, the first cable assembly includes two first cables 67, and the second cable assembly includes two second cables 68. On one of the outer rows of flexible photovoltaic supports, the upper ends of the two first cables 67 are respectively connected to the first end 61 and the second end 62 of the support frame 6, that is, connecting the wind-resistant cable 52 and one of the main cables 51. The lower ends of the two first cables 67 are connected to the same fixed point, and the two first cables 67 are arranged in a V-shape in the vertical direction. The upper ends of the two second cables 68 are respectively connected to the first end 61 and the third end 63 of the support frame 6, that is, connecting the wind-resistant cable 52 and one of the main cables 51. The lower ends of the two second cables 68 are connected to the same fixed point, and the two second 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 first cables 67 are respectively connected to the first end 61 and the fourth end 64 of the support frame 6, that is, connecting the wind-resistant cable 52 and another main cable 51. The lower ends of the two first cables 67 are connected to a fixed point, and the two first cables 67 are also arranged in a V-shape in the vertical direction. The upper ends of two second cables 68 are respectively connected to the first end 61 and the fourth end 64 of the support frame 6, that is, connecting the wind-resistant cable 52 and another main cable 51. The lower ends of the two second cables 68 are connected to another fixed point, and the two second cables 68 are also arranged in a V-shape in the vertical direction. In this way, the first cables 67 and the second cables 68 are symmetrically arranged, and the two first cables 67 and the support frame 6 form a stable triangular structure. The two second cables 68 and the support frame 6 also form a stable triangular structure, and both the upper and lower ends of the support frame 6 are connected to the ground. This 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.

[0068] In other embodiments, the distance between the ends of the first cable 67 and the second cable 68 connected to the support frame 6 is greater than the distance between the other ends of the first cable 67 and the second cable 68 connected to the fixing point. Furthermore, the other ends of the first cable 67 and the second cable 68 are connected to the same fixing point. Thus, the first cable 67 and the second cable 68 are arranged in a V-shape, forming a stable triangular structure with the support frame 6, which also improves the stability and wind resistance of the flexible photovoltaic array. It should be noted that the fixing point mentioned above can be a third foundation 13 located on the ground, or it can be the ground itself. That is, the first cable assembly and the second cable assembly can be fixed to different third foundations 13, or they can be directly fixed to different positions on the ground using connectors such as eye bolts.

[0069] Please see Figure 5 , Figure 6 , Figure 14 and Figure 15As shown, in this embodiment of the flexible photovoltaic array, a third 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 third wind-resistant component includes a crossbar 23 and a stay cable 24. The crossbar 23 is fixedly connected to two side columns 21 or central columns 22 of adjacent rows of flexible photovoltaic supports. The two ends of the stay cable 24 are respectively connected to two adjacent side columns 21 or two adjacent 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 two adjacent side columns 21 or 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. Clamping connectors 25 are fixedly installed at the upper and lower parts of the side columns 21 or the middle columns 22. The clamping connectors 25 have mounting holes 251. The crossbars 23 and the inclined cables 24 are connected to two adjacent side columns 21 or two adjacent 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.

[0070] In summary, compared with the prior art, the flexible photovoltaic array of this utility model has the following advantages: the flexible photovoltaic array forms an overall force-bearing system through the first wind-resistant component and the second wind-resistant component, thereby enhancing the overall integrity of the system and better resisting the impact of wind load on the photovoltaic module 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 third 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 in the longitudinal direction, the support frames 6 are connected together by a first wind-resistant assembly, with both ends connected to the ground by a second 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 is both flexible and stable and can adapt to complex terrain, thus having high stability and wind resistance to ensure the continuous and stable operation of photovoltaic projects.
