[0042] Please refer to Figures 1 to 16 As shown, the present invention discloses a photovoltaic flexible tracking bracket, comprising at least two columns 10, a driving device 20 and a flexible bracket cable structure, wherein at least two columns 10 are arranged at intervals. A rotating beam 30 is rotatably provided on the top of the column 10, and the flexible bracket cable structure is arranged between two adjacent rotating beams 30. The driving device 20 is used to drive the rotating beam 30 to rotate, so as to drive the photovoltaic panel 100 mounted on the flexible bracket cable structure to rotate, adjust the light receiving angle of the photovoltaic panel 100, so that it can receive more radiation and improve the power generation efficiency. A plurality of columns 10 are arranged at intervals along a first direction LL, and the columns 10 are arranged on a base surface (not marked in the figure), which can be a building top, plains, hills, mountains, lakes, deserts, Gobi and other places. The present invention does not limit the base surface.

[0043] See also Figure 5 The photovoltaic flexible tracking bracket includes a base 40, which is mounted on top of each column 10. A rotating beam 30 is pivotally mounted on the base 40. Each base 40 is mounted with a drive device 20, which includes a drive end connected to a corresponding rotating beam 30. Multiple drive devices 20 synchronously drive the corresponding rotating beams 30 to rotate.

[0044] See also Figure 1 The flexible support cable structure includes a first load-bearing cable 1 and a second load-bearing cable 2. The first load-bearing cable 1 and the second load-bearing cable 2 are arranged side by side and their ends are fixed to the rotating beam 30. The first load-bearing cable 1 and the second load-bearing cable 2 form a carrier that supports the photovoltaic panel 100.

[0045] See also Figure 3 and Figure 10The flexible support cable structure also includes a windproof cable 3, a support truss 4 and a roller assembly 5. The windproof cable 3 is located below the first load-bearing cable 1 and the second load-bearing cable 2 and is fixed at both ends. The support truss 4 includes an upper chord 41 and an arc rod 42, and the upper chord 41 connects the first load-bearing cable 1 and the second load-bearing cable 2. The arc rod 42 is located below the upper chord 41 and its two ends are fixedly connected to the two ends of the upper chord 41. The roller assembly 5 is movably connected to the arc rod 42, and the windproof cable 3 is connected to the roller assembly 5. Specifically, the roller assembly 5 rolls or slides along the arc rod 42 and is connected to the windproof cable 3 through the roller assembly 5. When the photovoltaic module is affected by wind, the roller assembly 5 can adaptively adjust its position on the arc rod 42 to reduce the force on the photovoltaic module, thereby reducing wind vibration and resisting negative wind.

[0046] The rotating beam 30 has a rotation center, which is located on the rotation centerline of the driving device 20. The center of the arc rod 42 is coaxial with the rotation center of the rotating beam 30. This coaxiality reduces shaking, allowing the arc rod 42 to slide or roll smoothly on the roller assembly 5.

[0047] In this embodiment, see Figure 11 The arc-shaped rod 42 includes a vertical portion 421 and an arc-shaped portion 422. The vertical portion 421 is fixed to the upper chord rod 41. Figure 6 The driving device 20 is arranged on one side of the rotating beam 30. The rotating beam 30 has a side wall 301 away from the flexible support cable structure. The driving end of the driving device 20 is connected to the side wall 301, and the connection between the driving end and the side wall 301 is the first connection. A support seat 302 is provided on the top of each rotating beam 30. The two ends of the first load-bearing cable 1 and the second load-bearing cable 2 are respectively fixedly connected to the corresponding support seat 302. The two ends of the first load-bearing cable 1 and the second load-bearing cable 2 are connected to the support seat 302 at the second connection and the third connection, respectively. The straight line where the second connection and the third connection are located is the reference line. The vertical distance between the first connection and the reference line is equal to the length of the vertical portion 421. Here, the vertical distance between the first connection and the reference line and the length of the vertical portion 421 are not required to be absolutely the same. Due to the existence of manufacturing and installation errors, when there is a certain error between the two, it should also be within the scope of protection of this patent application. Since there is a height difference between the load-bearing cable and the rotation center line of the driving device 20, the vertical portion 421 is provided to compensate for the height difference, so that the overall center of gravity of the supporting truss 4 moves downward and is concentric with the rotation center of the rotating beam 30, which is beneficial to improving the stability of the entire system.

[0048] See also Figure 14The roller assembly 5 includes a roller 51, a first U-shaped member 52, and a second U-shaped member 53. The roller 51 is rotatably connected to the first U-shaped member 52. A space is formed between the roller 51 and the bottom wall of the first U-shaped member 52, and the arc-shaped rod 42 is disposed in the space. The second U-shaped member 53 is fixed to the bottom surface of the first U-shaped member 52 and is connected to the windbreak cable 3 via a fixing assembly 6.

[0049] In some embodiments, see Figure 14 The fixing assembly 6 includes a U-bolt 61, a nut 62 adapted for the U-bolt 61, and a spacer 63 adapted for the U-bolt 61. A fixing cavity 64 is formed between the U-bolt 61 and the spacer 63. When the nut 62 is tightened, the spacer 63 moves, shrinking the cross-sectional area of ​​the fixing cavity 64 and ensuring the tension of the cable structure.

[0050] See also Figure 5 The ends of the windbreak cables 3 are connected with buckles 7, which are fixed at their ends. The support trusses 4 are distributed in the space enclosed by the first load-bearing cables 1, the second load-bearing cables 2, and the windbreak cables 3. The ends of the buckles 7 can be fixed to the columns 10 or to the base surface.

[0051] For details, see Figure 13 The cable buckle 7 comprises a columnar component 71, a third U-shaped component 72, and a spring 73. The third U-shaped component 72 has a connection hole 721, through which the columnar component 71 passes. One end of the columnar component 71 is provided with a stopper 711, and the other end of the columnar component 71 is connected to the windbreak cable 3. The spring 73 is sleeved over the columnar component 71, located between the stopper 711 and the panel surface where the connection hole 721 is located. The spring 73 acts as a buffer to mitigate installation errors.

[0052] In some embodiments, see Figure 13 The windbreak cable 3 is connected to a cable buckle 7 at both ends. The ends of the two cable buckles 7 are fixed to two adjacent columns 10. A clamp 50 is sleeved on the column 10. The clamp 50 is provided with a connecting portion 501. The third U-shaped component 72 is locked to the connecting portion 501 by bolts. The columnar component 71 is provided with a through hole. The end of the windbreak cable 3 passes through the through hole and is folded in half. The folded portion is locked with a U-shaped bolt and nut to achieve a fixed connection. In other embodiments, see Figure 15 and Figure 16 The end of the cable clasp 7 is fixed to the base surface. A cylindrical component 71 is externally threaded. A threaded barrel 74 is attached to the outer surface of the cylindrical component 71. This internal threaded barrel 74 is internally threaded. The external threads of the cylindrical component 71 connect with the internal threads of the barrel 74, allowing for fine-tuning of the length. The cable clasp 7 also includes a circular hook 75, which is connected to the windbreak cable 3. The lower end of the circular hook 75 is connected to the barrel 74. The other end of the third U-shaped component 72 is fixed to the connecting component of the base surface.

[0053] In this embodiment, the support truss 4 is connected to the first load-bearing cable 1, the second load-bearing cable 2, and the windbreak cable 3 via a fixing assembly comprising U-bolts, nuts, and spacers. Fastening the cables to the corners of the support truss 4 and using the spacers to further restrict their movement within the U-bolts reduces the risk of the support truss 4 slipping relative to the cables, thereby ensuring the tension of the cable structure and preventing cable slack.

[0054] In some embodiments, the flexible support cable structure further includes a stabilizing cable 8, and the support truss 4 further includes a lower chord 43. The ends of the lower chord 43 are connected to the arcuate rods 42, and the stabilizing cable 8 is connected to the lower chord 43. The upper chord 41 is arranged parallel to the lower chord 43, and two diagonal braces 44 are provided between the upper chord 41 and the lower chord 43 to provide stable support.

[0055] In this embodiment, the connection between the upper chord 41 and the diagonal strut 44, and the connection between the lower chord 42 and the diagonal strut 44 can be welded, riveted, or bolted. Bolt connection is the preferred choice, which is convenient for prefabrication, installation, disassembly and replacement; the two diagonal struts 44 improve the overall in-plane stability of the support truss 4, thereby enhancing the overall stability of the flexible support cable structure.

[0056] See also Figure 1 The flexible support cable structure further includes a support frame 9, which is distributed in the space surrounded by the first load-bearing cable 1, the second load-bearing cable 2 and the stabilizing cable 8, and the triangles of the support frame 9 are respectively connected to the first load-bearing cable 1, the second load-bearing cable 2 and the stabilizing cable 8. Figure 12 The support frame 9 includes a top rod 91 and two oblique rods 92 connected to the lower end of the top rod 91. The top rod 91 and the two oblique rods 92 form a triangular structure. The support frame 9 is arranged near the column 10 relative to the supporting truss 4.

[0057] The upper chord 41 and two diagonal braces 44 of the support truss 4 also form a triangular structure, and the triangular structure of the support frame 9 is smaller than the triangular structure of the support truss 4. Because the ends of the stabilizing cable 8 are at the same height as the ends of the load-bearing cable, the support frame 9 can gradually move the stabilizing cable 8 downward by moving the stabilizing cable 8 downward through the support truss 4.

[0058] In this embodiment, the first load-bearing cable 1, the second load-bearing cable 2, the windbreak cable 3, and the stabilizing cable 8 are preferably flexible steel cables with a long service life and strong load-bearing capacity. The first load-bearing cable 1 and the second load-bearing cable 2 are arranged in parallel; the first load-bearing cable 1 and the stabilizing cable 8 can also be arranged in parallel to facilitate tensioning.

[0059] In this embodiment, the number and spacing of the support trusses can be set according to the specific conditions of the photovoltaic flexible tracking bracket project site.

[0060] The arrangement of the first load-bearing cable 1, the second load-bearing cable 2 and the stabilizing cable 8 has a small cross-sectional height, which can improve the utilization rate of the lower space of the bracket, improve the ability of the structure to resist vibration, weaken the torsional effect of the cable structure, and reduce the risk of flipping and falling off of the photovoltaic panel.

[0061] In some embodiments, see Figure 6 and Figure 8 The base 40 includes a bottom plate 401, a first support plate 402 and a second support plate 403 vertically arranged on both sides of the bottom plate 401, the first support plate 402, the second support plate 403 and the bottom plate 401 form an accommodating cavity 404, the driving device 20 and the rotating beam 30 are arranged in the accommodating cavity 404, the driving device 20 is arranged close to the first support plate 402, and the rotating beam 30 is arranged close to the second support plate 403.

[0062] See also Figure 8 The driving device 20 includes a shell 201, a rotating body 202 arranged in the shell 201 and rotatable relative to the shell 201, and a motor installed on the shell 201. The motor is used to drive the rotating body 202 to rotate. The shell 201 is fixed on the first support plate 402, and the rotating body 202 is connected to the rotating beam 30.

[0063] In this embodiment, the driving device 20 and the rotating beam 30 are arranged in the fixed cavity 404, which has a compact structure, occupies a small space, has few components, is not easy to get stuck, is easy to install, and has low maintenance costs.

[0064] In this embodiment, the driving device 20 includes a rotary drive, which includes a housing 201 and a worm gear mechanism arranged in the housing 201. The worm gear mechanism includes a worm and a worm wheel engaged with the worm. The worm wheel is a rotating body 202, and the worm is connected to the driving end of the motor.

[0065] In this embodiment, see Figure 9 The driving device 20 adopts a worm gear type rotary drive. The housing 201 includes a first housing 2011 for accommodating the worm and a second housing 2012 for accommodating the worm gear. The rotating body 202 is arranged at one end of the second housing 2012 and is connected to the rotating beam 30. The other axial end of the second housing 2012 is fixed to the first support plate 402, which can improve the radial bearing capacity and axial bearing capacity of the driving device 20, and has a reverse self-locking function, which can withstand the lateral tension and vertical force transmitted by the flexible carrier.

[0066] In some embodiments, see Figure 8The first support plate 402, the second support plate 403 and the rotating beam 30 are respectively provided with corresponding through holes 601. A first bolt 602 is inserted from one side of the first support plate 402 into the through hole 601 of the first support plate 402, the driving device 20, the through hole 601 of the rotating beam 30 and the through hole 601 of the second support plate 403 and then locked, so that the first support plate 402 and the second support plate 403 are connected by the first bolt 602.

[0067] In this embodiment, the first support plate 402 is connected to the second support plate 403 via a first bolt 602, allowing the two support plates to jointly bear lateral tension, thereby improving the ability of the base 40 to resist lateral tension. The first bolt 602 passes through the through hole 601 of the first support plate 402, the drive device 20, the rotating beam 30, and the through hole 601 of the second support plate 403. This allows the force applied by the housing 201 of the drive device 20 to the first support plate 402 to be transmitted to the second support plate 403 via the first bolt 602. This allows the first support plate 402 and the second support plate 403 to bear the force together, thus avoiding local stress concentration on the base 40, minimizing deformation of the base 40, and facilitating improved bearing capacity of the base 40.

[0068] In some embodiments, see Figure 3 The photovoltaic flexible tracking bracket also includes a stay cable 70, one end of which is connected to the second support plate 403, and the other end of which is connected to the base surface. One end of the stay cable 70 is connected to the second support plate 403 and applies tension to the second support plate 403. The force applied to the second support plate 403 is partially transmitted to the first support plate 402 via the first bolt 602, so that the entire base 40 is subjected to the force, thereby preventing local stress concentration on the base 40 and improving the load-bearing capacity of the base 40.

[0069] In this embodiment, by providing the inclined cable 70, the overall tensile strength of the photovoltaic flexible tracking bracket is enhanced, the requirements for the bearing capacity of the column 10 and the base 40 can be reduced, materials are saved, and costs are reduced.

[0070] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of this specification should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention.
