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

[0035] Please see Figures 1 to 8As shown, this embodiment discloses a flexible photovoltaic support array. In this embodiment, the flexible photovoltaic support array is a flexible photovoltaic fixed support array, including at least two rows of flexible photovoltaic supports. Each row of flexible photovoltaic supports includes at least two columns 2, beams 3, cable structures 5, and support frames 6. At least two columns 2 are disposed at both ends of the flexible photovoltaic support, beams 3 are disposed at the upper end of each column 2, and the cable structures 5 are connected to the beams 3 at both ends for mounting photovoltaic modules 100. The support frames 6 are disposed on the cable structures 5 and support the entire cable structures 5.

[0036] 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.

[0037] In this embodiment, a beam 3 is supported by a column 2, and the middle support of the beam 3 is located at the upper end of the column 2. In this way, compared with the existing structure in which a column 2 is set at each end of the beam 3, the number of columns 2 is reduced, the structure of the flexible photovoltaic bracket is simplified, and the production and installation costs are reduced.

[0038] Please see Figure 1 As shown, at least two rows of flexible photovoltaic (PV) supports are arranged along a first direction D1, and each row of flexible PV supports is arranged along a second direction D2. Two columns 2 are arranged at both ends of each row of flexible PV supports along the second direction D2. Further, the flexible PV support array in this embodiment also includes tie rods 7. The columns 2 are vertically arranged on the ground, and the tie rods 7 connect the columns 2 to the ground. The columns 2, tie rods 7, and the ground form a triangular structure to improve the wind resistance and stability of each row of flexible PV supports. In this embodiment, each column 2 is connected to two tie rods 7, and the two tie rods 7 are arranged on both sides of the column 2 along the second direction D2 to improve the wind resistance of the flexible PV supports in the second direction D2.

[0039] Please see Figures 1 to 3 As shown, the flexible photovoltaic support array in this embodiment also includes a wind-resistant component 1, which is disposed between two adjacent rows of flexible photovoltaic supports to improve the inter-row wind resistance performance of the flexible photovoltaic support array. Specifically, the wind-resistant component 1 includes pulleys 11, steel cables 12, and counterweights 13. Two pulleys 11 are respectively disposed along the first direction D1 on the support frame 6 of two adjacent rows of flexible photovoltaic supports. The steel cable 12 is wound around the two pulleys 11, and both ends of the steel cable 12 are at least partially hanging below the two adjacent rows of flexible photovoltaic supports. Two counterweights 13 are respectively disposed at both ends of the steel cable 12. With this arrangement, the counterweights 13 provide their own downward gravity, and can absorb vibration energy through vertical displacement when strong winds occur, thereby improving the wind resistance performance of the flexible photovoltaic support array in the first direction D1 and thus improving the overall structural stability of the flexible photovoltaic support array.

[0040] Please see Figure 1 and Figure 2 As shown, in another embodiment, the flexible photovoltaic support array is a flexible photovoltaic tracking support array. Based on the previous embodiment, each row of flexible photovoltaic supports further includes a drive device 4. The drive end of the drive device 4 is mounted on the beam 3. The drive device 4 drives the beam 3 to rotate, thereby causing the cable structure 5 to rotate. With this configuration, the photovoltaic modules 100 on the cable structure 5 can rotate and change their tilt angle according to the change in the solar azimuth angle, thereby increasing power generation. The connection structure between the drive device 4 and the beam 3 is existing technology and will not be described in detail here.

[0041] Please see Figure 3 and Figure 6 As shown, the wind-resistant component 1 also includes mounting bases 14. Two mounting bases 14 are fixedly connected to two support frames 6 of two adjacent rows of flexible photovoltaic brackets along a first direction D1, and pulleys 11 are rotatably disposed on the mounting bases 14. Specifically, in this embodiment, the mounting base 14 includes a first mounting plate 141 and a second mounting plate 142 perpendicularly connected to the first mounting plate 141. The two second mounting plates 142 are disposed at both ends of the first mounting plate 141 along a second direction D2. The first mounting plate 141 is fixedly connected to the support frame 6, and the pulleys 11 are at least partially located between the two second mounting plates 142. Further, the pulleys 11 are rotatably disposed between the two second mounting plates 142, and steel cables 12 are wound around the two pulleys 11. With this configuration, when the beam 3 drives the cable structure 5 to rotate or the cable structure 5 is rotated by the wind, the counterweight 13 can follow the support frame 6 on the cable structure 5 to move up and down and absorb vibration energy. The two counterweights 13 are connected by steel cables 12 and two pulleys 11, which makes the friction of the counterweights 13 smaller and the flexibility higher when they move up and down.

[0042] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the steel cable 12 is wound around two pulleys 11. The steel cable 12 is at least partially attached to the side of the pulleys 11 closest to the support frame 6, and at least partially attached to the opposite sides of the two pulleys 11. This arrangement ensures high stability of the wind-resistant component 1, achieves mutual balance and restraint between the two counterweights 13, and thus improves the wind resistance performance between rows of the flexible photovoltaic support array. Furthermore, a groove 111 is provided around the radial outer periphery of the pulley 11, and the width of the groove 111 is less than the thickness of the pulley 11. The portion of the steel cable 12 wound around the pulley 11 is located within the groove 111 to limit the position of the steel cable 12 on the pulley 11 and prevent the steel cable 12 from slipping out.

[0043] Please see Figure 1 and Figure 2As shown, the cable structure 5 extends along the second direction D2 and includes two component cables 51 arranged parallel to the first direction D1 and two stabilizing cables 52 disposed below the component cables 51. The two ends of the component cables 51 and the two ends of the stabilizing cables 52 are fixed to two beams 3. The component cables 51 are used for fixed connection to the photovoltaic module 100. The support frame 6 connects the two component cables 51 and the two stabilizing cables 52. Furthermore, both the component cables 51 and the stabilizing cables 52 have tension towards their respective ends to provide effective support for the photovoltaic module 100.

[0044] In this embodiment, the two component cables 51 include a first component cable 511 and a second component cable 512 arranged along the first direction D1, and the two stabilizing cables 52 include a first stabilizing cable 521 and a second stabilizing cable 522 arranged along the first direction D1. The first component cable 511 and the second component cable 512 are respectively fixed to the first fixed point and the second fixed point of the support frame 6 by clamps, and the first stabilizing cable 521 and the second stabilizing cable 522 are respectively fixed to the third fixed point and the fourth fixed point of the support frame 6 by clamps. The first fixed point, the second fixed point, the third fixed point, and the fourth fixed point form the four corner points of a trapezoid. In the first direction D1, the first component cable 511 and the second component cable 512 are at least partially located between the first stabilizing cable 521 and the second stabilizing cable 522. This arrangement can ensure that the cable structure 5 maintains good stability even within a large range of rotation, making the entire row of photovoltaic modules 100 less prone to twisting and ensuring power generation. At the connection between the cable structure 5 and the beam 3, the first stabilizing cable 521 and the second stabilizing cable 522 are located between the first component cable 511 and the second component cable 512, and the stabilizing cable 52 is at a similar height to the component cable 51. Correspondingly, at the installation location of the photovoltaic module 100 on the cable structure 5, the first component cable 511 and the second component cable 512 are located between the first stabilizing cable 521 and the second stabilizing cable 522. This arrangement allows for the simultaneous generation of upward supporting force and inward tightening force on the stabilizing cable 52, which is inclined upwards between the two beams 3, preventing the stabilizing cable 52 from easily expanding outwards due to its location on the outer side of the bend in the middle. This further improves the overall structural stability and the smoothness of rotation of the cable structure 5.

[0045] Please see Figures 2 to 4As shown, the support frame 6 includes a first horizontal bar 61, a second horizontal bar 62 disposed opposite to the first horizontal bar 61, and two side bars 63 connecting the first horizontal bar 61 and the second horizontal bar 62. The first horizontal bar 61 is parallel to the second horizontal bar 62, and the length of the first horizontal bar 61 is less than the length of the second horizontal bar 62. The first horizontal bar 61 connects two component cables 51, the second horizontal bar 62 connects two stabilizing cables 52, and the two side bars 63 connect the same-side ends of the first horizontal bar 61 and the second horizontal bar 62, respectively. Further, the quadrilateral formed by the first horizontal bar 61, the second horizontal bar 62, and the two side bars 63 is a trapezoid, and the included angles between the two side bars 63 and the second horizontal bar 62 are all less than 90°; in some embodiments, the included angles between the two side bars 63 and the second horizontal bar 62 are equal, that is, the trapezoid formed by the first horizontal bar 61, the second horizontal bar 62, and the two side bars 63 is an isosceles trapezoid. With this configuration, when the tilt angle of the component cable 51 on which the photovoltaic module 100 is installed is too large, the two side rods 63 can effectively support the component cable 51 and the photovoltaic module 100, and the photovoltaic module 100 will not sag in an arc and thus twist, thereby improving the stability of the flexible photovoltaic support structure.

[0046] Please see Figure 2 and Figure 3 As shown, the support frame 6 also includes reinforcing rods 64, which are disposed within the quadrilateral formed by the first horizontal bar 61, the second horizontal bar 62, and the two side bars 63, and are used to enhance the structural strength and stability of the support frame 6. In this embodiment, the reinforcing rods 64 connect the first horizontal bar 61 and the second horizontal bar 62. Specifically, the support frame 6 is provided with two reinforcing rods 64, the upper ends of which are far apart from each other and respectively connected to the two ends of the first horizontal bar 61, and the lower ends of which are close together and connected to the middle of the second horizontal bar 62. The two reinforcing rods 64 are symmetrically arranged. This arrangement divides the quadrilateral formed by the first horizontal bar 61, the second horizontal bar 62, and the two side bars 63 into three triangles, giving the support frame 6 higher structural strength. In other embodiments, one or more reinforcing rods 64 are provided. This application does not limit the number or arrangement of reinforcing rods 64, and they can be set according to specific actual conditions.

[0047] Please see Figure 2 , Figure 3 and Figure 6 As shown, the wind-resistant component 1 is disposed on the second crossbar 62, and the mounting base 14 is fixedly connected to the side of the second crossbar 62 away from the first crossbar 61. The mounting base 14 is located in the middle of the second crossbar 62, so that the line of the tension force from the counterweight 13 on the support frame 6 deviates less from the center of gravity of the support frame 6, thereby improving overall stability. In this embodiment, the first mounting plate 141 of the mounting base 14 is provided with mounting holes 1411 for bolt connection with the second crossbar 62.

[0048] Please see Figure 1 and Figure 2 As shown, each row of flexible photovoltaic support includes multiple support frames 6, which are spaced apart along the second direction D2 on the cable structure 5. Each support frame 6 includes a first support frame 601 located in the middle of the cable structure 5 and multiple second support frames 602 located on both sides of the first support frame 601 along the second direction D2. The first support frame 601 connects with the first component cable 511, the second component cable 512, the first stabilizing cable 521, and the second stabilizing cable 522 to form a first set of four corner points. The second support frame 602 connects with the first component cable 511, the second component cable 512, the first stabilizing cable 521, and the second stabilizing cable 522 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. This arrangement allows the first stabilizing cable 521 and the second stabilizing cable 522 to form an arc-shaped structure, improving the stability and wind resistance of the cable structure 5. The support frames 6 effectively support the cable structure 5 and the photovoltaic module 100, preventing the photovoltaic module 100 from sagging and twisting, thus improving the overall structural stability.

[0049] Furthermore, the plurality of second support frames 602 include two first sub-support frames 603 and two second sub-support frames 604. The two first sub-support frames 603 are located on both sides of the first support frame 601 and are symmetrical with respect to the first support frame 601; the two second sub-support frames 604 are located on both sides of the first support frame 601 and are symmetrical with respect to the first support frame 601, and the second sub-support frames 604 are positioned away from the first support frame 601 relative to the first sub-support frames 603. The first sub-support frames 603 are connected to the first component cable 511, the second component cable 512, the first stabilizing cable 521, and the second stabilizing cable 522 to form a third set of four corner points. The second sub-support frames 604 are connected to the first component cable 511, the second component cable 512, the first stabilizing cable 521, and the second stabilizing cable 522 to form a fourth set of four corner points. The area of ​​the quadrilateral formed by the third set of four corner points is larger than the area of ​​the quadrilateral formed by the fourth set of four corner points. In this embodiment, the maximum distance between the two stabilizing cables 52 in the first direction D1 is the distance between them at the first support frame 601. This configuration further enhances the support capacity of the support frame 6 to the cable structure 5 and the photovoltaic module 100.

[0050] Please see Figures 1 to 3 , Figure 5 As shown, the mounting base 14 of the wind-resistant component 1 is fixed to the first support frame 601, and the mounting base 14 is aligned with the column 2 in the second direction D2. With this arrangement, the force generated by the wind-resistant component 1 on the two adjacent rows of flexible photovoltaic supports is relatively balanced and can restrain each other, thereby effectively improving the stability and wind resistance performance of the flexible photovoltaic support array.

[0051] Please see Figure 4 , Figure 7 and Figure 8As shown, the support frame 6 is connected to the cable structure 5 via a connector 8. The connector 8 includes a buckle 81, a locking block 82, and a bolt 83. The buckle 81 and the locking block 82 are fixedly connected by the bolt 83, and the buckle 81 and the locking block 82 cooperate to form a through hole 84 for the component cable 51 and the stabilizing cable 52 to pass through. Specifically, the buckle 81 is a U-shaped buckle, including an upper arc portion 811 and two fixing portions 812 at both ends of the upper arc portion 811. The locking block 82 includes a lower arc portion 821 and two through holes 822 at both ends of the lower arc portion 821. The upper arc portion 811 and the lower arc portion 821 cooperate to form a through hole 84 for the component cable 51 and the stabilizing cable 52 to pass through. The fixing portion 812 passes through the through hole 822, and the bolt 83 is used to lock the locking portion 82 to the outer periphery of the fixing portion 812 on the other side and abut against the locking block 82, thereby realizing the fixation of the connector 8 and the connection between the support frame 6 and the cable structure 5. In this embodiment, a connector 8 is provided on the first crossbar 61 and the second crossbar 62. The through hole 84 of the connector 8 on the first crossbar 61 is located on the side of the first crossbar 61 that is relatively far away from the second crossbar 62, and the through hole 84 of the connector 8 on the second crossbar 62 is located on the side of the second crossbar 62 that is far away from the first crossbar 61. That is, in the thickness direction of the photovoltaic module 100, the support frame 6 is located between the module cable 51 and the stabilizing cable 52.

[0052] In summary, compared with existing technologies, the flexible photovoltaic support array of this utility model has the following advantages: By setting a wind-resistant component 1 between two adjacent rows of flexible photovoltaic supports, the torsional vibration between rows is reduced. The wind-resistant component 1 includes pulleys 11, steel cables 12, and counterweights 13. Two pulleys 11 are respectively set on the support frame 6 of two adjacent rows of flexible photovoltaic supports. The steel cables 12 are wound around the two pulleys 11, and two counterweights 13 are respectively set at both ends of the steel cables 12 to provide downward gravity. By using the pulleys 11 and counterweights 13, the tilt angle of the photovoltaic modules 100 is adjusted by the driving device 4, so that the flexible photovoltaic support can follow the change of the solar azimuth angle. At the same time, when strong winds occur, the vertical displacement of the counterweights 13 absorbs vibration energy, increasing structural safety and energy storage. This flexible photovoltaic support array has strong wind resistance and high overall stability, and can resist the torsional vibration of the photovoltaic modules under wind load, thereby reducing the risk of microcracks in the photovoltaic modules 100 and damage to the cable structure 5, achieving the effect of improving structural stability and extending the life of the entire flexible photovoltaic support array.
