[0002] Flexible photovoltaic (PV) support structures mainly consist of prestressed first and second prestressed cable components that directly support the PV modules, with stabilizing cables providing auxiliary support. Compared to rigid PV support structures, flexible PV support structures have disadvantages such as poor structural stability and poor wind resistance, which can easily lead to PV modules flipping over in strong winds.

[0003] In related technologies, a connecting rod structure is set between two adjacent rows of flexible photovoltaic supports to resist wind. However, the rigid structure of the connecting rod has poor flexibility, especially during installation, the length of the connecting rod needs to be controlled according to the distance between rows, and its poor versatility cannot meet the needs of flexible photovoltaic tracking supports.

[0042] Example 1:

[0043] Please refer to Figures 1 to 15 As shown, this utility model discloses a flexible photovoltaic system, including a cross-type wind-resistant flexible photovoltaic support array and photovoltaic modules 200. The cross-type wind-resistant flexible photovoltaic support array includes at least two rows of flexible photovoltaic supports 1 and a wind-resistant mechanism 2. The flexible photovoltaic supports 1 are used to support the photovoltaic modules 200. In this embodiment, the flexible photovoltaic supports 1 are flexible photovoltaic tracking supports.

[0044] Please refer to Figure 14 and Figure 15As 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 connected to the cable structure 12, and a drive device 14. Photovoltaic modules 200 are mounted on the cable structure 12 of each row of flexible photovoltaic support 1 via clamps. The drive device 14 drives the crossbeams 15 to rotate, thereby rotating the photovoltaic modules 200 mounted on the cable structure 12, adjusting the light-receiving angle of the photovoltaic modules 200 so that they can receive more irradiation and improve power generation efficiency.

[0045] Please refer to Figure 1 As shown, at least two rows of flexible photovoltaic supports 1 include first flexible photovoltaic supports 1a and second flexible photovoltaic supports 1b that are adjacent to each other. Support frames 13 include a first support frame 13a disposed on the first flexible photovoltaic supports 1a and a second support frame 13b disposed on the second flexible photovoltaic supports 1b. Wind-resistant mechanisms 2 include a first damper 21 and a second damper 22, both of which are rotatably connected to the first support frame 13a and the second support frame 13b.

[0046] Please refer to Figure 15 As shown, each row of flexible photovoltaic support 1 also includes a base 16 disposed on the top of each column 11 and a drive device 14 mounted on the base 16. A crossbeam 15 is rotatably disposed on the base 16. The drive device 14 is disposed 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 modules 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. The motor is connected to the worm gear in the worm gear mechanism via a transmission. The worm gear is connected to the crossbeam 15 through the aforementioned power output component. The structure of the drive device 14 is prior art and will not be described in detail here.

[0047] Please refer to Figure 1 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 14As 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 fixing point and the second fixing point 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. The first stabilizing cable 1221 and the second stabilizing cable 1222 are in an upwardly curved arc shape. When the component cable rotates under the drive of the drive device 14, the prestress of the bottom 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 in the center of rotation. If this torque is not overcome, after a period of use, it will cause the photovoltaic module to twist, so that the photovoltaic modules 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 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 upward to overcome its gravity, thereby improving the wind resistance performance. The vertical direction here refers to the vertical direction perpendicular to the ground when the flexible photovoltaic support is fixed to the ground. The horizontal direction here refers to the horizontal direction when looking from one side column to the other side column when the flexible photovoltaic support is fixed to the ground.

[0048] Please refer to Figure 2 and Figure 13 As shown, the first support frame 13a includes a first top support rod 131a, a first bottom support rod 132a parallel to the first top support rod 131a, and a plurality of first diagonal braces 133a. The plurality of first diagonal braces 133a connect the first top support rod 131a and the first bottom support rod 132a. The first support frame 13a includes a first top support 1312 disposed at the end of the first top support rod 131a and a first bottom support 1322 disposed at the end of the first bottom support rod 132a. Both the first top support 1312 and the first bottom support 1322 are used to connect the wind-resistant mechanism 2. Since the first flexible photovoltaic bracket 1a is usually provided with multiple first support frames 13a, the first support frame 13a used to connect the wind-resistant mechanism 2 among the multiple first support frames 13a is provided with a first top support 1312 and a first bottom support 1322. The first support frame 13a that is not connected to the wind-resistant mechanism 2 among the multiple first support frames 13a may not be provided with a first top support 1312 and a first bottom support 1322.

[0049] Please refer to Figure 2 and Figure 13As shown, the second support frame 13b includes a second top support rod 131b, a second bottom support rod 132b parallel to the second top support rod 131b, and a plurality of second diagonal braces 133b. The plurality of second diagonal braces 133b connect the second top support rod 131b and the second bottom support rod 132b. The second support frame 13b includes a second top support 1332 disposed at the end of the second top support rod 131b and a second bottom support 1342 disposed at the end of the second bottom support rod 132b. Both the second top support 1332 and the second bottom support 1342 are used to connect the wind-resistant mechanism 2. Since the second flexible photovoltaic bracket 1b is usually provided with multiple second support frames 13b, the second support frame 13b used to connect the wind-resistant mechanism 2 among the multiple second support frames 13b is provided with a second top support 1332 and a second bottom support 1342. The second support frame 13b not connected to the wind-resistant mechanism 2 among the multiple second support frames 13b may not be provided with a second top support 1332 and a second bottom support 1342.

[0050] The two ends of the first damper 21 are rotatably connected to the first top support rod 131a and the second bottom support rod 132b, respectively, and the two ends of the second damper 22 are rotatably connected to the first bottom support rod 132a and the second top support rod 131b, respectively. For details, please refer to... Figure 2 As shown, the two ends of the first damper 21 are rotatably connected to the first top support 1312 and the second bottom support 1342, respectively, and the two ends of the second damper 22 are rotatably connected to the first bottom support 1322 and the second top support 1332, respectively. Please refer to... Figure 6 As shown, the first top support 1312 and the first bottom support 1322 are offset in the width direction WW of the support frame 13, and the second top support 1332 and the second bottom support 1342 are also offset in the width direction WW of the support frame 13. This offset arrangement prevents interference between the first damper 21 and the second damper 22.

[0051] The first top support 1312 and the second bottom support 1342 are located on the first side of the support frame 13 in the width direction WW; the first bottom support 1322 and the second top support 1332 are located on the second side of the support frame 13 in the width direction WW; the projections of the first damper 21 and the second damper 22 in the second plane are parallel to each other; the second plane is a horizontal plane perpendicular to the first plane.

[0052] Please refer to Figure 7 and Figure 8As shown, the first top support 1312, the first bottom support 1322, the second top support 1332, and the second bottom support 1342 have the same structure, each including a fixed plate 13121, two support plates 13122 disposed on the fixed plate 13121, and a pin connecting the two support plates 13122. The two support plates 13122 and the fixed plate form a mounting groove 13120. Both ends of the first damper 21 and the second damper 22 have mounting portions, which are disposed within the mounting groove 13120 and pivoted on the pin. In some embodiments, the mounting portions pivot on the pin via a fisheye bearing, so that both ends of the first damper 21 and both ends of the second damper can move omnidirectionally relative to the support frame 13, improving installation efficiency.

[0053] In some embodiments, the first damper 21 and the second damper 22 are both telescopic structures with adjustable lengths, which can track the movement of the flexible photovoltaic support 1 in real time to provide wind resistance for at least two rows of flexible photovoltaic supports 1.

[0054] In some implementation methods, please refer to Figure 1 As shown, the projections of the first damper 21 and the second damper 22 in the first plane intersect each other, and the first plane is perpendicular to the length direction LL of the flexible photovoltaic support 1. By setting the first damper 21 and the second damper 22 to intersect, the torsional vibration of the photovoltaic module under wind load is resisted. Furthermore, the projections of the first damper 21 and the second damper 22 in the second plane are parallel to each other and have a gap. This arrangement can prevent the first damper 21 and the second damper 22 from interfering with each other during the movement following the flexible photovoltaic support 1.

[0055] Please refer to Figure 9 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. Please refer to... Figure 12 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 first outer tube 211 can rotate about the axis of the first inner tube 212, and the second outer tube 221 can rotate about the axis of the second inner tube 222. During slow-speed stretching, there is no damping force between the first outer tube 211 and the first inner tube 212, which does not affect tracking. During rapid stretching, a large damping force is generated between the first outer tube 211 and the first inner tube 212, which is beneficial for resisting strong winds.

[0056] Please refer to Figures 9 to 12As shown, both the first outer tube 211 and the first inner tube 212 have a first mounting portion 210 at their ends that are far apart from each other. Both the second outer tube 221 and the second inner tube 222 have a second mounting portion 220 at their ends that are far apart from each other. The first mounting portion 210 has a first channel 2101, and the second mounting portion 220 has a second channel 2201. A first pin passes through the first channel 2101 of one of the first mounting portions 210 of the first damper 21 and the hole in the support plate 13122 of the first top support 1312. A second pin passes through the first channel 2101 of the other first mounting portion 210 of the first damper 21 and the hole in the support plate 13122 of the second bottom support 1342, so that the first damper 21 can rotate up and down relative to the support frame 13 around the first pin and the second pin. A third pin passes through the second hole 2201 of a second mounting part 220 of the second damper 22 and the hole of the support plate 13122 of the first bottom support 1322. A fourth pin passes through the second hole 2201 of another second mounting part 220 of the second damper 22 and the hole of the support plate 13122 of the second top support 1332, so that the second damper 22 can rotate up and down relative to the support frame 13 around the third pin and the fourth pin.

[0057] The first damper 21 and the second damper 22 provided by this invention can both adjust their lengths in real time, allowing the flexible photovoltaic support 1 to maintain a tracking range of ±60° under normal wind speeds. Simultaneously, the first damper 21 and the second damper 22 can absorb vibration energy, increasing structural safety. The cross-arrangement of the first damper 21 and the second damper 22 helps resist the torsional vibration of the photovoltaic module under wind loads, thereby reducing the risk of microcracks in the photovoltaic module and damage to the flexible cable structure 12, improving structural stability, and extending the lifespan of the entire tracking system.

[0058] Example 2:

[0059] 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 driving device and a base. The crossbeam and the column are relatively non-rotatable. By setting a wind-resistant mechanism between the two rows of flexible photovoltaic supports, the wind-resistant mechanism includes a first damper and a second damper. The first damper and the second damper are length-extendable structures, which are highly versatile and have flexible and efficient installation.

[0060] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
