[0002] Flexible photovoltaic (PV) mounting systems consist of PV modules mounted on steel cables, with both ends of the cables fixed to crossbeams at the top of columns.

The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

[0039] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention.

[0040] Please refer to Figures 1 to 11This utility model discloses a flexible photovoltaic support array 10. The flexible photovoltaic support array 10 includes at least two rows of flexible photovoltaic supports 1 and a wind-resistant mechanism 2. Each row of flexible photovoltaic supports 1 includes a plurality of columns 11 spaced apart, a crossbeam 12 disposed on the top of each column 11, a cable structure 13 connecting two crossbeams 12, and a support frame 14 connected to the cable structure 13.

The support frame 14 includes a first support frame 14A disposed on the first flexible photovoltaic support 1A and a second support frame 14B disposed on the second flexible photovoltaic support 1B. The wind-resistant mechanism 2 includes a telescopic rod 21 and a damper 22. The telescopic rod 21 includes a first rod 211 and a second rod 212 that slide along the telescopic direction of the rod 21. The first rod 211 is pivotally connected to the first flexible photovoltaic support 1A, and the second rod 212 is pivotally connected to the second flexible photovoltaic support 1B. One end of the damper 22 is pivotally connected to the first flexible photovoltaic support 1A, and the other end is pivotally connected to either the first rod 211 or the second rod 212. This allows the wind-resistant mechanism 2 to provide resistance when the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B move relative to each other, reducing the swaying, flipping, or twisting of each row of flexible photovoltaic supports 1 and improving the wind resistance performance of the flexible photovoltaic supports 1. In a first embodiment, both the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B are flexible fixed supports. The angle between the crossbeams 12 on the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B and the ground is a fixed value. By setting the wind-resistant mechanism 2, the wind resistance performance between the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B is improved.

[0041] Please refer to Figures 2 to 8 The pivot connection point of the first rod 211 and the first flexible photovoltaic support 1A, one end of the damper 22 and the pivot connection point of the first flexible photovoltaic support 1A, and the other end of the damper 22 and the pivot connection point of the first rod 211 or the second rod 212 form the three corner points of a triangle. The overall structure of the wind-resistant mechanism 2 is more stable, so as to improve the wind resistance performance of two adjacent rows of flexible photovoltaic supports 1 in a strong wind environment.

[0042] Specifically, the first rod 211 is pivotally connected to the cable structure 13 of the first support frame 14A or the first flexible photovoltaic bracket 1A, and the second rod 212 is pivotally connected to the cable structure 13 of the second support frame 14B or the second flexible photovoltaic bracket 1B. One end of the damper 22 is pivotally connected to the cable structure 13 of the first support frame 14A or the first flexible photovoltaic bracket 1A, and the other end of the damper 22 is pivotally connected to the first rod 211 or the second rod 212.

[0043] Please refer to Figures 5 to 8The first rod 211 includes a first body 2111 and a first connector 2112. One end of the first connector 2112 is connected to the first body 2111, and the other end of the first connector 2112 is pivotally connected to the first support frame 14A. The second rod 212 includes a second body 2121 and a second connector 2122. One end of the second connector 2122 is connected to the second body 2121, and the other end of the second connector 2122 is pivotally connected to the second support frame 14B. Preferably, the second body 2121 is fitted inside the first body 2111, and the second body 2121 is telescopically movable within the first body 2111. In other embodiments, one of the first body 2111 and the second body 2121 is a sliding groove, and the other of the first body 2111 and the second body 2121 is a slider. The sliding groove and the slider slide together, allowing relative movement between the first body 2111 and the second body 2121. Alternatively, the first body 2111 and the second body 2121 may have other structures so that the first body 2111 and the second body 2121 can move relative to each other.

[0044] Please refer to Figures 5 to 8 The other end of the first connecting member 2112 is connected to the first support frame 14A via a pin, allowing the first body 2111 to pivot relative to the first support frame 14A. The other end of the second connecting member 2122 is connected to the second support frame 14B, allowing the second body 2121 to rotate relative to the second support frame 14B. Preferably, adjacent first support frames 14A and second support frames 14B are laterally oriented and have the same structural dimensions. The two ends of the telescopic rod 21 are set at the same height, meaning the two ends of the telescopic rod 21 are connected to the same height positions of the first support frame 14A and the second support frame 14B. Alternatively, the two ends of the telescopic rod 21 are inclined, meaning the two ends of the telescopic rod 21 are connected to different height positions of the first support frame 14A and the second support frame 14B. By rotatably connecting the first connecting member 2112 to the first support frame 14A and the second connecting member 2122 to the second support frame 14B, the height difference between the first support frame 14A and the second support frame 14B can be accommodated, improving wind resistance while also facilitating assembly. In other embodiments, the first connector 2112 is connected to the cable structure 13 in the same row as the first support frame 14A, and the second connector 2122 is connected to the cable structure 13 in the same row as the second support frame 14B.

[0045] Please refer to Figure 5 , Figure 8 as well as Figure 10The wind-resistant mechanism 2 also includes a rotating seat 23 disposed on the first body 2111. The damper 22 includes a damper body 221 and a damper telescopic rod 222 that extend and retract from each other. One end of the damper body 221 is rotatably connected to the rotating seat 23, and one end of the damper telescopic rod 222 is rotatably connected to the first support frame 14A. In this embodiment, the damper body 221 extends and retracts within the damper telescopic rod 222. Specifically, the rotating seat 23 includes two opposing support plates 231 and a first pivot shaft 232 connecting the two support plates 231. One end of the damper body 221 is disposed on the first pivot shaft 232 via a fisheye bearing 24. The first support frame 14A includes a polygon formed by multiple struts. One strut includes two opposing fixed plates and a second pivot shaft 141 connecting the two fixed plates. One end of the damper telescopic rod 222 is disposed on the second pivot shaft 141 via a fisheye bearing 24. In this embodiment, the strut is the component cable strut 142 described below, thus enabling universal connection by providing the fisheye bearing 24. When the first support frame 14A and the second support frame 14B of the two rows of flexible photovoltaic brackets 1 connected by the wind-resistant mechanism 2 are vertically or laterally misaligned, the fisheye bearing 24 allows the telescopic rod 21 and the damper 22 to adaptively adjust their angles, avoiding friction.

[0046] The cable structure 13 includes a component cable 131 and a stabilizing cable 132. The stabilizing cable 132 is located below the component cable 131. The component cable 131 is used for fixed connection of the photovoltaic module 20. The component cable 131 includes a first component cable 1311 and a second component cable 1312 arranged in the left-right direction. The stabilizing cable 132 includes a first stabilizing cable 1321 and a second stabilizing cable 1322 arranged in the left-right direction. The first component cable 1311 and the first stabilizing cable 1321 are arranged vertically correspondingly, and the second component cable 1312 and the second stabilizing cable 1322 are also arranged vertically correspondingly. The first component cable 1311 and the first stabilizing cable 1321 pass through one end of the crossbeam 12 together, and the second component cable 1312 and the second stabilizing cable 1322 pass through the other end of the crossbeam 12 together. In this embodiment, the first connector 2112 is connected to the first stabilizing cable 1321 in the same row as the first flexible photovoltaic support 1A via a fisheye bearing 24, the second connector 2122 is connected to the second stabilizing cable 1322 in the same row as the second flexible photovoltaic support 1B via a fisheye bearing 24, and the damper telescopic rod 222 is connected to the first component cable 1311 in the same row as the first flexible photovoltaic support 1A via a fisheye bearing 24. This arrangement can also improve the wind resistance performance of the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B.

[0047] Please refer to Figures 5 to 9The first support frame 14A and the second support frame 14B have the same structure. The specific structure of the first support frame 14A is described below. The first support frame 14A includes a component cable support rod 142, a stabilizing cable support rod 143 disposed relative to the component cable support rod 142, and a plurality of side support rods 144 connecting the component cable support rod 142 and the stabilizing cable support rod 143. Preferably, the side support rods 144 include a first side support rod 1441 and a second side support rod 1442. The length of the component cable support rod 142 is less than the length of the stabilizing cable support rod 143. The same end of the first side support rod 1441 and the second side support rod 1442 are respectively fixedly connected to both ends of the component cable support rod 142 by bolts, and the other same end of the first side support rod 1441 and the second side support rod 1442 are respectively fixedly connected to both ends of the stabilizing cable support rod 143 by bolts. Furthermore, the first side support rod 1441 and the second side support rod 1442 extend outwards in the left-right direction. This allows the first support frame 14A to form a trapezoidal structure. In other embodiments, the length of the component cable strut 142 is greater than the length of the stabilizing cable strut 143. The first component cable 1311 and the second component cable 1312 are fixed to the first and second fixing points of the component cable strut 142 by clamps 15. The first stabilizing cable 1321 and the second stabilizing cable 1322 are fixed to the third and fourth fixing points of the stabilizing cable strut 143 by clamps 15. The first, second, third, and fourth fixing points form the four corner points of a trapezoid to improve the wind resistance of the cable structure 13.

[0048] The side support rod 144 also includes a third side support rod 1443 and a fourth side support rod 1444. The third side support rod 1443 and the fourth side support rod 1444 are respectively connected between the component cable support rod 142 and the stabilizing cable support rod 143, and the third side support rod 1443 and the fourth side support rod 1444 are located between the first side support rod 1441 and the second side support rod 1442. Preferably, one end of the third side support rod 1443 is fixedly connected to the component cable support rod 142 by bolts at the connection point near the first side support rod 1441 and the component cable support rod 142, and the other end of the third side support rod 1443 is fixedly connected to the center of the stabilizing cable support rod 143 by bolts. The first side support rod 1441, the third side support rod 1443, and the stabilizing cable support rod 143 form a triangular structure. One end of the fourth side support rod 1444 is fixedly connected to the component cable support rod 142 near the connection point of the second side support rod 1442 and the component cable support rod 142 by bolts. The other end of the fourth side support rod 1444 is fixedly connected to the center of the stabilizing cable support rod 143 by bolts. The second side support rod 1442, the fourth side support rod 1444, and the stabilizing cable support rod 143 form a triangular structure. This further improves the overall stability of the first support frame 14A, thereby improving the overall wind resistance of the cable structure 13.

[0049] Please refer to Figures 5 to 6 , Figures 8 to 9The component cable support rod 142 and the stabilizing cable support rod 143 are provided with reinforcing rods 16 near their ends. A triangle is formed between the reinforcing rod 16, the adjacent side support rod 144, and either the component cable support rod 142 or the stabilizing cable support rod 143. In this embodiment, the reinforcing rod 16 is disposed on the side of the first support frame 14A facing the telescopic rod 21 and the damper 22. Furthermore, the reinforcing members of the first support frame 14A and the second support frame 14B are arranged face-to-face. Specifically, the reinforcing rod 16 includes a first reinforcing rod 161 and a second reinforcing rod 162. The first reinforcing rod 161 is integrally disposed with the component cable support rod 142, extending laterally outward from the end of the component cable support rod 142, such that the free end of the first reinforcing rod 161 is vertically aligned with the stabilizing cable support rod 143. The two ends of the second reinforcing rod 162 are respectively fixedly connected to the ends of the first reinforcing rod 161 and the stabilizing cable support rod 143 by bolts. In this way, a triangular structure is formed between the first reinforcing rod 161, the second reinforcing rod 162 and the stabilizing cable support rod 143, which further improves the structural strength between the first support frame 14A, the damper 22 and the telescopic rod 21, and further improves the wind resistance performance.

[0050] Please refer to Figure 10 In this embodiment, one end of the first rod 211 of the telescopic rod 21 is pivotally connected to the end of the stabilizing cable support rod 143 of the first support frame 14A via a fisheye bearing 24, and one end of the second rod 212 is pivotally connected to the end of the stabilizing cable support rod 143 of the second support frame 14B via a fisheye bearing 24. One end of the damper 22 is pivotally connected to the end of the first reinforcing rod 161 or the second reinforcing rod 162 via a fisheye bearing 24. This allows the wind-resistant mechanism 2 to provide resistance when the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B move relative to each other, reducing the swaying, flipping, or twisting of each row of flexible photovoltaic supports 1 and improving the wind resistance performance of the flexible photovoltaic supports 1. When the flexible photovoltaic support array 10 consists of multiple rows of flexible photovoltaic supports 1, the telescopic rod 21 and the damper 22 of the wind-resistant mechanism 2 can adapt to its attitude changes, meeting the real-time angle requirements of the flexible photovoltaic supports 1, exhibiting high versatility. Furthermore, the damper 22 can provide damping for adjacent rows of flexible photovoltaic supports 1, especially in strong wind environments, significantly improving its wind resistance performance.

[0051] Please refer to Figure 5Multiple first support frames 14A are spaced apart along the extension direction of the cable structure 13. Each first support frame 14A includes a first central support frame 14A1 located in the middle of the cable structure 13 and multiple first side support frames 14A2 located on both sides of the first central support frame 14A1 along the extension direction of the cable structure 13. The first central support frame 14A1 is connected to the first component cable 1311, the second component cable 1312, the first stabilizing cable 1321, and the second stabilizing cable 1322 to form a first set of four corner points. The first side support frames 14A2 are connected to the first component cable 1311, the second component cable 1312, the first stabilizing cable 1321, and the second stabilizing cable 1322 to form a second set of four corner points. The area of ​​the quadrilateral formed by the first set of four corner points is larger than the area of ​​the quadrilateral formed by the second set of four corner points, causing the first stabilizing cable 1321 and the second stabilizing cable 1322 to be concave upwards, thereby improving the wind resistance performance of the flexible photovoltaic support 1.

[0052] Please refer to Figures 1 to 2 as well as Figure 11 In the second embodiment, the flexible photovoltaic support array 10 is a flexible photovoltaic tracking support array. When the flexible photovoltaic support array 10 is composed of multiple rows of flexible tracking photovoltaic supports, the telescopic rod 21 and damper 22 of the wind-resistant mechanism 2 can adapt to its attitude changes, meet the requirements of real-time angle changes of the flexible photovoltaic tracking support, and have high versatility. Furthermore, the damper 22 can provide damping for adjacent rows of flexible photovoltaic supports 1, especially in windy conditions, which can significantly improve its wind resistance performance. During slow-speed movement and extension, the damper 22 has no damping force and does not affect tracking. During rapid movement and extension, the damper 22 generates a large damping force, which is beneficial for resisting strong winds.

[0053] Each row of flexible photovoltaic support brackets 1 also includes a base 17 disposed on the top of each column 11 and a drive device 18 mounted on the base 17. A crossbeam 12 is rotatably disposed on the base 17. The drive device 18 is disposed between the crossbeam 12 and the base 17. The drive device 18 includes a power output component connected to the crossbeam 12. The drive device 18 is used to drive the crossbeam 12 to rotate, thereby driving the cable structure 13 and the photovoltaic modules 20 mounted on the cable structure 13 to rotate. In this way, by setting a wind-resistant mechanism 2 between two adjacent rows of flexible photovoltaic tracking brackets, the wind-resistant mechanism 2 can provide resistance when the first row of flexible photovoltaic tracking brackets and the second row of flexible photovoltaic tracking brackets move relative to each other, reducing the swaying, flipping or twisting of each row of flexible photovoltaic tracking brackets and improving the wind resistance performance of the flexible photovoltaic tracking brackets. When the flexible photovoltaic support array 10 is a multi-row flexible photovoltaic tracking support, the telescopic rod 21 and damper 22 of the wind-resistant mechanism 2 can adapt to its attitude changes and meet the real-time angle requirements of the flexible photovoltaic tracking support. It has high versatility, and the damper 22 can provide damping for two adjacent rows of flexible photovoltaic tracking supports. Especially in windy environments, it can greatly improve its wind resistance performance.

[0054] In this embodiment, the first stabilizing cable 1321 and the second stabilizing cable 1322 in the cable structure 13 are curved upwards. When the component cable 131 rotates under the drive of the drive device 18, the prestress of the bottommost stabilizing cable (such as the first stabilizing cable 1321) can generate an upward supporting force. The torque formed by the supporting force around the center of gravity of the photovoltaic module 20 can overcome or offset the torque formed when the center of gravity of the photovoltaic module 20 is not at the center of rotation. If this torque is not overcome, after a period of use, it will cause the photovoltaic module 20 to twist, so that the photovoltaic modules 20 in the middle position and the position close to the foundation structure are not on the same plane, which affects the power generation. The technical solution of this patent application can ensure that all photovoltaic modules 20 are on the same plane. The stabilizing cable on the other side (such as the second stabilizing cable 1322) can generate a force to resist the wind applied to the front of the module and support the photovoltaic module 20 upwards to overcome its gravity, thereby improving wind resistance.

[0055] This utility model also discloses a flexible photovoltaic system, which includes a flexible photovoltaic support array 10, a cable structure 13 installed on each row of flexible photovoltaic supports 1, and photovoltaic modules 20. The photovoltaic modules 20 are installed on the cable structure 13 via clamps 210. This ensures the stability of the photovoltaic modules 20, improves their wind resistance, reduces the likelihood of swaying, flipping, or twisting of the photovoltaic modules 20 on the flexible photovoltaic supports 1, and lowers maintenance costs. The flexible photovoltaic support 1 can be a flexible photovoltaic tracking support or a flexible photovoltaic fixed support.

[0056] In summary, the flexible photovoltaic support array 10 of this utility model includes at least two rows of flexible photovoltaic supports 1 and a wind-resistant mechanism 2. The wind-resistant mechanism 2 includes a telescopic rod 21 and a damper 22. The telescopic rod 21 includes a first rod 211 and a second rod 212 that slide along the telescopic direction of the telescopic rod 21. The first rod 211 is pivotally connected to the first flexible photovoltaic support 1A, and the second rod 212 is pivotally connected to the adjacent second flexible photovoltaic support 1B. One end of the damper 22 is connected to the first flexible photovoltaic support 1A, and the other end is pivotally connected to the first rod 211 or the second rod 212. This allows the wind-resistant mechanism 2 to provide resistance when the first flexible photovoltaic support 1A and the second flexible photovoltaic support 1B move relative to each other, reducing the swaying, flipping, or twisting of each row of flexible photovoltaic supports 1 and improving the wind resistance performance of the flexible photovoltaic supports 1.

[0057] When the flexible photovoltaic support array 10 is a multi-row flexible photovoltaic tracking support, the telescopic rod 21 and damper 22 of the wind-resistant mechanism 2 can adapt to its attitude changes, meet the requirements of real-time angle tracking of the flexible photovoltaic tracking support, have high versatility, and the damper 22 can provide damping for two adjacent rows of flexible photovoltaic tracking supports, especially in windy environments, which can greatly improve its wind resistance performance.
