[0036] Example 1:

[0037] Please refer to Figures 1 to 11 As shown, this utility model discloses a flexible photovoltaic system, including a flexible support array 100 with a wind-damping mechanism and photovoltaic modules 200. The flexible support array 100 with the wind-damping mechanism includes at least two rows of flexible photovoltaic supports 1 and wind-damping mechanisms 2. The wind-damping mechanisms 2 are connected to adjacent rows of flexible photovoltaic supports 1, playing a role in wind resistance and reducing the risk of photovoltaic modules 200 flipping. In this embodiment, the flexible photovoltaic support 1 is a flexible photovoltaic tracking support.

[0038] Please refer to Figure 1 and Figure 2 As shown, each row of flexible photovoltaic support 1 includes multiple spaced columns 11, a crossbeam 15 at the top of each column 11, a cable structure 12 connecting two crossbeams 15, a support frame 13 connecting the cable structure 12, and a drive device 14. Please refer to... Figure 5 As shown, photovoltaic modules 200 are mounted on cable structures 12 of each row of flexible photovoltaic brackets 1 via clamps 18. A drive device 14 drives the crossbeam 15 to rotate, thereby rotating the photovoltaic modules 200 mounted on the cable structures 12, adjusting the light-receiving angle of the photovoltaic modules 200 to allow them to receive more irradiance and improve power generation efficiency. Multiple columns 11 are spaced apart along the second direction LL. The columns 11 are set on a base surface (not shown in the figure), which can be a building roof, plain, hill, mountain, lake, desert, Gobi, etc. This invention does not limit the base surface.

[0039] Please refer to Figure 1As shown, at least two rows of flexible photovoltaic supports 1 include a first flexible photovoltaic support 1a and a second flexible photovoltaic support 1b that are adjacent to each other. The first flexible photovoltaic support 1a and the second flexible photovoltaic support 1b are spaced apart along a first direction WW, and the first direction WW is perpendicular to the second direction LL.

[0040] Please refer to Figure 2 As shown, a base 16 is provided on the top of the column 11, and a crossbeam 15 is pivotally mounted on the base 16. Each base 16 is equipped with a drive device 14, which is located between the crossbeam 15 and the base 16. The drive device 14 includes a power output component connected to the crossbeam 15. The drive device 14 drives the crossbeam 15 to rotate, thereby driving the cable structure 12 and the photovoltaic module 200 mounted on the cable structure 12 to rotate. In this embodiment, the drive device 14 is a combination of a motor and a rotary drive mechanism. The rotary drive mechanism includes a housing and a worm gear structure disposed within the housing. The housing is fixedly connected to the base 16, and the motor is driven by the worm gear in the worm gear mechanism. The worm gear is connected to the crossbeam through the aforementioned power output component.

[0041] Please refer to Figure 4 As shown, the cable structure 12 includes a module cable 121 and a stabilizing cable 122. The stabilizing cable 122 is located below the module cable 121, and the module cable 121 is used for fixed connection with the photovoltaic module 200. The end of the module cable 121 is fixed to the crossbeam 15, and the end of the stabilizing cable 122 is also fixed to the crossbeam 15. Please refer to... Figure 5 As shown, component cable 121 includes a first component cable 1211 and a second component cable 1212 arranged in the left-right direction, and stabilizing cable 122 includes a first stabilizing cable 1221 and a second stabilizing cable 1222 arranged in the left-right direction. The first component cable 1211 and the second component cable 1212 are fixed to the first and second fixing points of the top support rod of the support frame 13 by clamps. The first stabilizing cable 1221 and the second stabilizing cable 1222 are respectively fixed to the third and fourth fixing points of the bottom support rod of the support frame 13 by clamps. The first, second, third, and fourth fixing points form the four corner points of a trapezoid. Here, the up-down direction refers to the vertical direction perpendicular to the ground when the flexible photovoltaic support is fixed to the ground. The left-right direction refers to the left-right direction when looking from one side column to the other side column when the flexible photovoltaic support is fixed to the ground.

[0042] In this embodiment, the first stabilizing cable 1221 and the second stabilizing cable 1222 in the cable structure are curved upwards. When the module cable rotates under the drive of the drive device 14, the prestress of the bottommost stabilizing cable (such as the first stabilizing cable 1221) can generate an upward supporting force. The torque formed by the supporting force around the center of gravity of the photovoltaic module can overcome or offset the torque formed when the center of gravity of the photovoltaic module is not at the center of rotation. If this torque is not overcome, after a period of use, it will cause the photovoltaic module to twist, making the photovoltaic modules in the middle position and those near the foundation structure not on the same plane, affecting the power generation. The technical solution of this patent application can ensure that all photovoltaic modules are on the same plane. The stabilizing cable on the other side (such as the second stabilizing cable 1222) can generate a force to resist the wind applied to the front of the module and support the photovoltaic module upwards to overcome its gravity, improving wind resistance. Please refer to Figure 7 As shown, the support frame 13 includes a first support rod 131, a second support rod 132 parallel to the first support rod 131, and several diagonal braces 133. The first support rod 131 is the bottom support rod, and the second support rod 132 is the top support rod. The several diagonal braces 133 connect the first support rod 131 and the second support rod 132. Please refer to... Figure 11 As shown, a first cable buckle 134 for the stabilizing cable 122 to pass through is installed on the first support rod 131. A second cable buckle 135 for the component cable 121 to pass through is installed on the second support rod 132.

[0043] The cross-section of the first support rod 131 is U-shaped. For details, please refer to... Figure 11 As shown, the first support rod 131 includes a first sidewall portion 1311, a second sidewall portion 1312 opposite to the first sidewall portion 1311, and a bottom wall portion 1313 connecting the first sidewall portion 1311 and the second sidewall portion 1312. The space enclosed by the first sidewall portion 1311, the second sidewall portion 1312, and the bottom wall portion 1313 forms a mounting groove 130. A notch 1314 is provided in the area of ​​the bottom wall portion 1313 opposite to the first connecting portion 2121 or the third connecting portion 2221. The end of the diagonal brace 133 is provided in the mounting groove 130 and is fixedly connected to the first sidewall portion 1311 and the second sidewall portion 1312 by a fastening assembly. Here, the fastening assembly is a bolt and nut structure.

[0044] Please refer to Figure 1 and Figure 2 As shown, the flexible photovoltaic support 1 also includes a stay cable 17, one end of which is connected to the base 16, and the other end of which is connected to the pile foundation. By setting the stay cable 17, the overall tensile strength of the flexible photovoltaic support 1 is enhanced.

[0045] In some implementation methods, please refer to Figure 3 and Figure 6As shown, the wind-resistant damping mechanism 2 includes a first damper 21, a second damper 22, and a connecting rod 23 connecting the first damper 21 and the second damper 22. The end of the first damper 21 furthest from the connecting rod 23 is rotatably connected to the support frame 13 of the first flexible photovoltaic support 1a, and the end of the second damper 22 furthest from the connecting rod 23 is rotatably connected to the support frame 13 of the second flexible photovoltaic support 1b. This allows the wind-resistant damping mechanism 2 to move freely within the tracking angle along with the flexible photovoltaic support 1. When the damper moves and extends slowly, the damper 22 has no damping force and does not affect tracking. When the damper moves and extends rapidly, the damper 22 generates a large damping force, which is beneficial for resisting strong winds.

[0046] Specifically, the first damper 21 and the second damper 22 are connected to the first support rod 131 of the two support frames 13. That is, during the design process, there is no need to set up an additional damper mounting structure; they can simply be connected to the existing support frame 13.

[0047] The first damper 21 and / or the second damper 22 are length-extendable structures. During the rotation of the flexible photovoltaic support 1, the length of the wind-resistant damping mechanism 2 is adaptively adjusted according to the rotation angle of the flexible photovoltaic support 1, enabling the wind-resistant damping mechanism 2 to track the movement of the flexible photovoltaic support 1 in real time, thus making it suitable for steep terrain. The damping coefficient and stroke of the first damper 21 and / or the second damper 22, as well as the length of the connecting rod 23, are all set according to the spacing between two adjacent rows of flexible photovoltaic supports 1, but it is not necessary to precisely determine the spacing between the two rows of flexible photovoltaic supports 1, because each damper has a relatively telescopic rod. In the embodiment illustrated in this utility model, both the first damper 21 and the second damper 22 are length-extendable structures. Of course, in other embodiments, one of the first damper 21 and the second damper 22 is a telescopic structure.

[0048] In another embodiment, the wind-resistant damping mechanism 2 includes a first damper 21 and a second damper 22. The second damper 22 is connected to the first damper 21 end-to-end or back-to-back. End-to-end connection means the telescopic rod of the first damper 21 is connected to the body of the second damper 22, the body of the first damper 21 is connected to the first flexible photovoltaic support 1a, and the telescopic rod of the second damper 22 is connected to the second flexible photovoltaic support 1b; or the body of the first damper 21 is connected to the telescopic rod of the second damper 22, with the telescopic rod of the first damper 21 connected to the first flexible photovoltaic support 1a and the body of the second damper 22 connected to the second flexible photovoltaic support 1b. Back-to-back connection means the body of the first damper 21 is connected to the body of the second damper 22, the telescopic rod of the first damper 21 is connected to the first flexible photovoltaic support 1a, and the telescopic rod of the second damper 22 is connected to the second flexible photovoltaic support 1b. Both the first damper 21 and the second damper 22 are telescopic structures. The first flexible photovoltaic support 1a is connected to the second flexible photovoltaic support 1b through the first damper 21 and the second damper 22.

[0049] In another embodiment, the wind-resistant damping mechanism 2 includes only a first damper 21. The body of the first damper 21 is connected to the first photovoltaic flexible support 1a, and the telescopic rod is connected to the second photovoltaic flexible support 1b. The first damper 21 is a length-extendable structure.

[0050] Please refer to Figure 7 As shown, the first damper 21 includes a first outer tube 211 and a first inner tube 212 movably disposed within the first outer tube 211. The first inner tube 212 is rotatably connected to the first support rod 131 of the support frame 13 by a first bolt 10. The first outer tube 211 is fixedly connected to the connecting rod 23 by a second bolt 20. For details, please refer to... Figure 9 and Figure 10 As shown, the first inner tube 212 includes a first connecting portion 2121, which is cylindrical in shape and has a first hole 2120. The first connecting portion 2121 is located in the mounting groove 130 of the first support rod 131, and a first bolt 10 passes through the groove wall hole of the mounting groove 130 and the first hole 2120 of the first connecting portion 2121. Specifically, the first bolt 10 passes through the hole in the first side wall portion 1311, the hole in the second side wall portion 1312, and the first hole 2120 of the first connecting portion 2121. There is a gap between the first bolt 10 and the hole wall of the first hole 2120, that is, the first connecting portion 2121 and the first bolt 10 are not fixed, and the first connecting portion 2121 can rotate around the first bolt 10.

[0051] Please refer to Figure 10As shown, the first outer tube 211 includes a second connecting portion 2111, which is rectangular in shape and has a second hole 2110. The connecting rod 23 is a round tube with a cavity 230 and a first connecting hole 231 at one end. The second connecting portion 2111 is located in the cavity 230, and a second bolt 20 passes through the first connecting hole 231 of the connecting rod 23 and the second hole 2110 of the second connecting portion 2111, thereby achieving a fixed connection between the first outer tube 211 and the connecting rod 23.

[0052] Please refer to Figure 7 and Figure 8 As shown, the second damper 22 includes a second outer tube 221 and a second inner tube 222 movably disposed within the second outer tube 221. The second inner tube 222 is rotatably connected to the first support rod 131 of the support frame 13 by a third bolt 30. The second outer tube 221 is fixedly connected to the connecting rod 23 by a fourth bolt 40. The first inner tube 212 and the second inner tube 222 of the same wind-damping mechanism 2 are respectively connected to the support frames 13 of adjacent rows. Since the flexible photovoltaic support 1 can be arranged in two or more rows, the two ends of the support frame 13 are respectively used to connect the first inner tube 212 of one wind-damping mechanism 2 and the second inner tube 222 of another wind-damping mechanism 2.

[0053] For details, please refer to Figure 9 and Figure 10 As shown, the second inner tube 222 includes a third connecting portion 2221, which is cylindrical and has a third hole 2220. The third connecting portion 2221 is located in the mounting groove 130 of the first support rod 131. A third bolt 30 passes through the groove wall hole of the mounting groove 130 and the third hole 2220 of the third connecting portion 2221. Specifically, the third bolt 30 passes through the hole in the first side wall portion 1311, the hole in the second side wall portion 1312, and the third hole 2220 of the third connecting portion 2221. There is a gap between the third bolt 30 and the wall of the third hole 2220. That is, the third connecting portion 2221 and the third bolt 30 are not fixed, and the third connecting portion 2221 can rotate around the third bolt 30.

[0054] Please refer to Figure 10 As shown, the second outer tube 221 includes a fourth connecting part 2211, which has a fourth hole 2210. The other end of the connecting rod 23 has a second connecting hole 232. The fourth connecting part 2211 is located in the cavity 230, and the fourth bolt 40 passes through the second connecting hole 232 of the connecting rod 23 and the fourth hole 2210 of the fourth connecting part 2211, thereby achieving a fixed connection between the second outer tube 221 and the connecting rod 23.

[0055] Please refer to Figure 11As shown, in order to enable the wind-damping mechanism 2 to achieve a larger rotation angle relative to the support frame 13, a section is cut off at both ends of the bottom wall portion 1313 of the first support rod 131, forming a notch 1314 in the cut-off area. The two notches 1314 of the same first support rod 131 are respectively opposite to the first connecting portion 2121 and the third connecting portion 2221 of different wind-damping mechanisms 2. The notches 1314 avoid the rotation of the wind-damping mechanism 2, enabling the wind-damping mechanism 2 to achieve a larger rotation angle, which is beneficial for adapting to steep terrain.

[0056] Example 2:

[0057] The difference between this and Embodiment 1 is that the flexible photovoltaic support is a flexible fixed support, that is, it does not have a drive device 14 and a base 16. The crossbeam 15 and the column 11 are relatively non-rotatable. By setting a wind-resistant damping mechanism between the two rows of flexible photovoltaic supports, the wind-resistant damping mechanism includes a first damper. The first damper is a length-extendable structure with high versatility and flexible and efficient installation.
