[0030] In one embodiment, as Figures 1 to 5As shown, the embodiment of the present application provides a tracking flexible photovoltaic support 1, which can specifically include a support assembly 100 and an angle adjustment assembly 200, wherein the support assembly 100 mainly includes two oppositely arranged load-bearing main ropes 110 and a plurality of mounting beams 120, the plurality of mounting beams 120 are arranged at equal intervals along the extension direction of the load-bearing main rope 110, and the two ends of each mounting beam 120 are rotatably connected with a load-bearing main rope 110 respectively, the mounting beam 120 is used for mounting a photovoltaic assembly, and the photovoltaic assembly includes a plurality of photovoltaic panels arranged in sequence along the length direction of the mounting beam 120. The angle adjustment assembly 200 mainly includes a plurality of linkage structures 210, a linkage rope 220 and a power module 230 for driving the linkage rope 220 to move back and forth in the extension direction of the load-bearing main rope 110, the plurality of linkage structures 210 are arranged in one-to-one correspondence with the plurality of mounting beams 120, and each linkage structure 210 is arranged in linkage between the linkage rope 220 and the corresponding mounting beam 120, so as to be driven by the linkage rope 220 to move back and forth to drive the corresponding mounting beam 120 to rotate clockwise or counterclockwise.

[0031] It can be understood that the tracking flexible photovoltaic support 1 of the embodiment of the present application is mainly used for supporting and fixing a single-row multi-group photovoltaic assembly, that is, each mounting beam 120 mentioned above can be used for supporting and fixing a group of photovoltaic assemblies. The specific number of photovoltaic panels in each group of photovoltaic assemblies can be adjusted arbitrarily according to actual needs, and the tracking flexible photovoltaic support 1 only needs to provide mounting beams 120 with corresponding lengths. Generally, the mounting beam 120 mentioned above can be arranged in a round rod structure or a square rod structure according to actual needs, and is preferably arranged in a round rod structure to better meet the mounting and fixing needs of the plurality of photovoltaic panels.

[0032] In work, the tracking flexible photovoltaic support 1 can drive the linkage rope 220 to move back and forth in the extension direction of the load-bearing main rope 110 through the power module 230, so that each mounting beam 120 rotates clockwise or counterclockwise under the linkage of the corresponding linkage structure 210, thereby driving the corresponding photovoltaic assembly (i.e. a plurality of photovoltaic panels) to adjust the same irradiation angle, so that the irradiation angle is always kept at the best position to obtain the maximum solar radiation energy.

[0033] In this way, in the embodiment of the present application, through the above structure, the single power module 230 can synchronously realize the rotary driving of the single-row multi-group photovoltaic assembly (or the multi-row photovoltaic panel), so that it rotates along the movement track of the sun at any time, that is, through the single angle adjustment assembly 200, the irradiation angle adjustment of the single-row multi-group photovoltaic assembly (or the multi-row photovoltaic panel) can be realized synchronously, so that the tracking flexible photovoltaic support 1 can make the whole photovoltaic system simple in structure, energy-saving and environment-friendly, and strong in economy.

[0034] In some examples, asFigures 3 to 5 As shown, the linkage structure 210 comprises a slide rail 211 and a sliding connector 212 in sliding cooperation with the slide rail 211, the slide rail 211 is arranged on the corresponding mounting beam 120 and extends along the radial direction of the mounting beam 120. The sliding connector 212 is arranged on the linkage cable 220 to move back and forth along the corresponding slide rail 211 under the driving of the back and forth movement of the linkage cable 220, thereby driving the corresponding mounting beam 120 to rotate clockwise or counterclockwise through the corresponding slide rail 211. In this way, through the above structural arrangement, when the linkage cable 220 moves to the right as shown in Figure 3 under the driving of the power module 230, the slide rail 211 drives the corresponding mounting beam 120 to rotate counterclockwise through the sliding cooperation between the sliding connector 212 and the slide rail 211. Conversely, when the linkage cable 220 moves to the left as shown in Figure 3 under the driving of the power module 230, the slide rail 211 drives the corresponding mounting beam 120 to rotate clockwise through the sliding cooperation between the sliding connector 212 and the slide rail 211.

[0035] In some examples, as shown in Figures 3 to 5 , the mounting beam 120 comprises a beam body 121 and a slide rail 211 seat 122, the two ends of the beam body 121 are respectively rotationally connected with a load-bearing main cable 110, one end of the slide rail 211 seat 122 is fixedly arranged at the middle of the beam body 121, the other end of the slide rail 211 seat 122 extends along the radial direction of the beam body 121, and the slide rail 211 is a hole structure arranged on the slide rail 211 seat 122 and extending along the length direction of the slide rail 211 seat 122. In this way, through the above structural arrangement, the slide rail 211 can be better arranged on the corresponding mounting beam 120 while the slide rail 211 extends along the radial direction of the mounting beam 120, thereby when the sliding connector 212 moves back and forth along the corresponding slide rail 211 under the driving of the back and forth movement of the linkage cable 220, the corresponding slide rail 211 can better give the corresponding mounting beam 120 a pulling force to drive the corresponding mounting beam 120 to rotate clockwise or counterclockwise.

[0036] It can be understood that the beam body 121 in the present example can be arranged in a round rod structure or a square rod structure according to actual needs, and is preferably arranged in a round rod structure to better meet the installation and fixing needs of multiple photovoltaic panels. The slide rail 211 seat 122 in the present example can be arranged in any regular or irregular shape according to actual needs, as long as the main body thereof extends along the radial direction of the beam body 121.

[0037] In some examples, as shown in Figures 3 to 5As shown, the sliding connector 212 comprises a sliding part and a connecting part, one side of the connecting part is fastened to the linkage cable 220 through at least one hoop structure, the other side of the connecting part is fixed with the sliding part, and the end of the sliding part away from the connecting part is slidingly clamped in the hole structure of the corresponding slide rail 211. In this way, through the above structural arrangement, the sliding connector 212 can be more firmly fastened to the linkage cable 220, so that the linkage cable 220 can more stably drive each sliding connector 212 to move.

[0038] It can be understood that in the present example, each connecting part can be fastened to the linkage cable 220 through two hoop structures to ensure that the connection between each connecting part and the linkage cable 220 is more firm and stable. The hoop structure in the present example can be a conventional hoop structure, i.e., each hoop structure can be composed of at least one U-shaped connector and two screw structures, so that after the U-shaped connector is wound around the linkage cable 220 and the corresponding connecting part is inserted, the connection between the two is locked by the two screw structures.

[0039] In some examples, as shown in Figure 1 , Figure 3 and Figure 4 , the power module 230 comprises a driving wheel 231, a driven wheel 232, and a motor structure (not shown) for driving the driving wheel 231 to rotate, the driving wheel 231 and the driven wheel 232 are oppositely arranged in the extension direction of the load main cable 110, and the linkage cable 220 is wound around the driving wheel 231 and the driven wheel 232. In this way, through the above structural arrangement, under the action of the motor structure driving the driving wheel 231 to rotate, the linkage cable 220 is driven to move back and forth along the extension direction of the load main cable 110 through the combined cooperation of the driving wheel 231 and the driven wheel 232. Further, the support assembly 100 further comprises a driving wheel 231 stand 130 and a driven wheel 232 stand 140, the driving wheel 231 stand 130 and the driven wheel 232 stand 140 are oppositely arranged in the extension direction of the load main cable 110, the driving wheel 231 is arranged at the top end of the driving wheel 231 stand 130, the motor structure is arranged on the driving wheel 231 stand 130 and is drivingly connected with the driving wheel 231, and the driven wheel 232 is arranged at the top end of the driven wheel 232 stand 140. In this way, through the above structural arrangement, it can be ensured that the entire power module 230 is well installed and fixed. Further, the rotation direction of the driving wheel 231 is the circumferential direction of the driving wheel 231 stand 130, and the rotation direction of the driven wheel 232 is the circumferential direction of the driven wheel 232 stand 140. In this way, through the above structural arrangement, the driving wheel 231 is more convenient to rotate and is arranged at the top end of the driving wheel 231 stand 130, and the driven wheel 232 is more convenient to rotate and is arranged at the top end of the driven wheel 232 stand 140, while the circulation direction of the entire linkage cable 220 is located on the same horizontal plane, so as to ensure that the linkage cable 220 moves back and forth more stably.

[0040] It can be understood that the motor structure in the example can specifically include a power motor and a speed reduction motor, so as to more stably drive the driving wheel 231 to rotate through cooperation between the two. Figure 3 Thus, the maximum movement distance of the linkage cable to the right or to the left can be limited by regulating the number of rotations of the power motor, and the linkage cable is ensured to stop when it moves to the maximum distance, thereby avoiding interference between the linkage cable and the photovoltaic assembly due to excessive rotation angle of the photovoltaic assembly.

[0041] In some examples, as shown in Figure 1 , Figure 2 both ends of the mounting beam 120 are rotatably connected to a bearing main cable 110 through a bearing structure 300. Thus, each end of the mounting beam 120 can be rotatably connected to the corresponding bearing main cable 110 through the above structure. Further, the bearing structure 300 includes a bearing member 310 and a mounting seat 320, one side of the mounting seat 320 is fastened to the corresponding bearing main cable 110 through at least one hoop structure, and the other side of the mounting seat 320 is rotatably connected to the corresponding end of the corresponding mounting beam 120 through the bearing member 310. Thus, the bearing structure 300 can be more firmly fastened to the bearing main cable 110 through the above structure, so that the corresponding end of the corresponding mounting beam 120 can be more stably rotatably connected to the bearing main cable 110 through the bearing structure 300.

[0042] It can be understood that each mounting seat 320 in the example can be fastened to the bearing main cable 110 through two hoop structures to ensure that the connection between each mounting seat 320 and the bearing main cable 110 is more firm and stable. The hoop structure in the example can be a conventional hoop structure, that is, each hoop structure can be composed of at least one U-shaped connecting piece and two screw structures, so that the U-shaped connecting piece is wrapped around the bearing main cable 110 and passes through the corresponding mounting seat 320, and the connection between the two is locked through the two screw structures. In addition, the bearing member 310 described above is fastened to the other side of the mounting seat 320 on the outer periphery side, and is fixed to the corresponding end of the corresponding mounting beam 120 on the inner periphery side. Thus, the corresponding end of the corresponding mounting beam 120 can be more stably rotatably connected to the bearing main cable 110 through the rotation cooperation between the inner periphery side and the outer periphery side in the bearing member 310.

[0043] In some examples, as shown in Figure 1 , Figure 3 and Figure 4As shown, the support assembly 100 further comprises at least four end supports 150, which are distributed in a rectangular shape, and two ends of one load-bearing main cable 110 are fixedly arranged at the top of two end supports 150, and two ends of another load-bearing main cable 110 are fixedly arranged at the top of the other two end supports 150. In this way, the support and fixation of the two load-bearing main cables 110 can be achieved through the above structure.

[0044] It can be understood that the end supports 150 in the present example preferably adopt the A-shaped architecture shown in the figure to ensure that they have better stable support, thereby ensuring the structural stability and reliability of the entire photovoltaic system.

[0045] The above merely describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the inventive concept of the present application is included in the patent protection scope of the present application.
