For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0039] Reference below Figures 1-9A support structure 100 for a photovoltaic flexible support according to an embodiment of the present application is described.

[0040] like Figures 1-9 As shown, the support structure 100 for the photovoltaic flexible bracket according to the embodiment of the present application includes: a support rod 10 and a connecting structure 20. The connecting structure 20 can be set on the support rod 10, and the connecting structure 20 can be connected to the cable 200 to support the cable 200.

[0041] The connecting structure 20 may include a support ear 21 and a roller 22. The support ear 21 may be arranged on the support rod 10, and the roller 22 may be rotatably arranged between the support rod 10 and the support ear 21. The cable 200 may pass through the roller 22, and the cable 200 may be supported between the roller 22 and the support ear 21. On the one hand, based on ensuring that the cable 200 is in contact with the roller 22 and moves normally, the cable 200 may be limited to prevent the cable 200 from being separated from the roller 22, thereby improving the reliability of the support for the cable 200. On the other hand, the cable 200 may be prevented from interfering with the support ear 21, thereby preventing the cable 200 from being scratched and damaged by the support ear 21 during movement, thereby improving the service life of the cable 200.

[0042] It can be understood that the movement of the cable 200 can drive the roller 22 to rotate. Compared with the solution in which the cable 200 is locked to the support rod 10 through a connecting structure 20 such as a wire rope clamp or a sheet metal lock, on the basis of ensuring the support effect of the cable 200, the friction between the cable 200 and the connecting structure 20 can be reduced, that is, the form of the friction between the cable 200 and the connecting structure 20 is converted from static friction or sliding friction to rolling friction, thereby reducing the friction between the cable 200 and the support structure 100.

[0043] On the one hand, the front and rear tensions of the cable 200 at the connecting structure 20 can be kept consistent, which can reduce the local stress difference of the cable 200 when subjected to external loads, thereby reducing the tension loss of the cable 200 and improving the utilization efficiency of the cable 200. On the other hand, the force exerted by the cable 200 on the supporting structure 100 when subjected to external loads can be reduced, that is, the force on the supporting structure 100 can be reduced, which can increase the service life of the supporting structure 100, and compared with the solution of increasing the cross-section of the supporting structure 100 (for example, the support rod 10) to increase the force limit of the supporting structure 100, it can reduce costs.

[0044] According to the support structure 100 for a photovoltaic flexible bracket according to an embodiment of the present application, a support ear 21 and a roller 22 are provided on the support rod 10, and the cable 200 passes through the roller 22 and is supported between the roller 22 and the support ear 21, so that the movement of the cable 200 can drive the roller 22 to rotate, which can reduce the friction between the cable 200 and the support rod 10, so that the front and rear tension of the cable 200 at the roller 22 can be kept consistent, which can reduce the local stress difference of the cable 200 when subjected to external loads, reduce the tension loss of the cable 200, and improve the utilization efficiency of the cable 200. At the same time, it can reduce the force of the cable 200 on the support structure 100 when subjected to external loads, which can improve the service life of the support structure 100 and reduce costs.

[0045] like Figure 2-Figure 6 As shown, according to some embodiments of the present application, the roller 22 can be set between the support rod 10 and the support ear 21 through the rotating shaft 50. For example, the rotating shaft 50 can be rotatably set between the support rod 10 and the support ear 21, and the roller 22 can be set on the rotating shaft 50; or, the rotating shaft 50 can be set between the support rod 10 and the support ear 21, and the roller 22 can be rotatably set on the rotating shaft 50, which can realize support for the roller 22 and ensure the normal rotation of the roller 22.

[0046] The support rod 10 and the support ear 21 may have an axial hole 2122, and the rotating shaft 50 may be sequentially passed through the axial hole 2122 on the support ear 21 and the axial hole on the support rod 10, that is, the end of the rotating shaft 50 (such as Figure 5 The left and right ends shown in the figure can be rotatably connected to the axial hole on the support rod 10 and the axial hole 2122 on the support ear 21 respectively, and the roller 22 can be set on the rotating shaft 50. The movement of the cable 200 can drive the roller 22 and the rotating shaft 50 to rotate together, which can improve the smoothness of the rotation of the roller 22 and reduce the friction between the cable 200 and the connecting structure 20.

[0047] Alternatively, the end of the rotating shaft 50 (such as Figure 5 The left and right ends shown in the figure can be fastened to the support rod 10 and the support ear 21 respectively, and the roller 22 is rotatably set on the rotating shaft 50. The movement of the cable 200 can drive the roller 22 to rotate relative to the rotating shaft 50, which can improve the support effect of the roller 22 and the stability of the rotation of the roller 22, thereby improving the stability of the movement of the cable 200.

[0048] like Figure 3 and Figure 5As shown, in some embodiments, the support structure 100 for the photovoltaic flexible bracket further includes: two gaskets 30, the two gaskets 30 can be set on the rotating shaft 50, one gasket 30 can be located between the support rod 10 and the roller 22, and the gasket 30 can contact the support rod 10 and the roller 22 respectively, so as to fill the gap between the roller 22 and the support rod 10 and prevent the roller 22 from moving closer to the support rod 10 when rotating (such as Figure 3 The other gasket 30 can be located between the support ear 21 and the roller 22, and the gasket 30 can contact the support ear 21 and the roller 22 respectively, so as to fill the gap between the roller 22 and the support ear 21 and prevent the roller 22 from moving closer to the support ear 21 (as shown in the right to left direction) during rotation. Figure 3 from left to right as shown).

[0049] Thus, the roller 22 can be prevented from rotating along the axial direction of the rotating shaft 50 (such as Figure 5 It can be understood that the gasket 30 can be a thrust bearing (for example, a thrust roller bearing), which can reduce the resistance to the rotation of the roller 22 on the basis of preventing the roller 22 from shifting during rotation, thereby improving the smoothness of the rotation of the roller 22.

[0050] like Figure 5 As shown, in some embodiments, the support structure 100 for the photovoltaic flexible bracket further includes: a reinforcement block 40, which can be set on the inner wall of the support rod 10, and the end of the shaft 50 (such as Figure 5 The left end shown in the figure can be connected to the support rod 10, so that the end of the rotating shaft 50 can extend into the support rod 10, and the part of the rotating shaft 50 extending into the support rod 10 can be connected to the reinforcing block 40, that is, the reinforcing block 40, the support rod 10 and the supporting ear 21 can cooperate with each other, which can improve the supporting effect of the rotating shaft 50.

[0051] Moreover, by providing the reinforcing block 40, the structural strength of the connection between the support rod 10 and the rotating shaft 50 can be improved, and the support rod 10 can be prevented from bending or breaking when the cable 200 is subjected to an external load, the service life of the support rod 10 can be increased, and compared with the solution of increasing or optimizing the cross-section of the support rod 10 to increase the force limit of the support rod 10, the cost can be reduced; it can be understood that the rotating shaft 50 can rotate relative to the reinforcing block 40, and on the basis of improving the support effect on the rotating shaft 50, the normal rotation of the rotating shaft 50 can be guaranteed, which is conducive to improving the smoothness of the rotation of the roller 22.

[0052] like Figure 3 and Figure 5As shown, according to some embodiments of the present application, the outer periphery of the roller 22 may have a roller groove 221, and the cable 200 may be supported on the inner wall of the roller groove 221, so as to limit the cable 200 and prevent the cable 200 from being separated from the roller 22 during movement, thereby improving the stability of the cable 200 movement and improving the support effect on the cable 200.

[0053] like Figure 3 and Figure 6 As shown, according to some embodiments of the present application, the support ear 21 includes: a support segment 212 and two connecting segments 211, the two connecting segments 211 are arranged at intervals, and the two connecting segments 211 are respectively connected to the opposite sides of the support rod 10 (such as Figure 3 The front and rear sides shown in the figure are connected to improve the connection effect between the support ear 21 and the support rod 10. The support segment 212 can be set between the two connecting segments 211, and the opposite sides of the support segment 212 (such as Figure 6 The front and rear sides shown in the figure can be connected to the two connecting sections 211 respectively, that is, the support ear 21 can be a bent part, which is easy to process and install while ensuring the structural strength of the support ear 21.

[0054] The support section 212 can be arranged at intervals from the support rod 10, and space can be reserved for the installation of the roller 22 and the rotating shaft 50. The support section 212 can have an axial hole 2122, so that the roller 22 can be rotatably set between the support rod 10 and the support section 212, so that the support rod 10 and the support section 212 cooperate to support the two ends of the rotating shaft 50, which can improve the supporting effect of the rotating shaft 50 and the roller 22, and is conducive to improving the stability of the rotation of the roller 22.

[0055] It can be understood that by providing the connecting section 211, the contact area between the support ear 21 and the support rod 10 can be increased, which is beneficial to improving the connection effect between the support ear 21 and the support rod 10, wherein the support ear 21 can be welded to the support rod 10 through the connecting section 211 to improve the connection effect between the support ear 21 and the support rod 10, or the connecting section 211 can be connected to the support rod 10 by fasteners such as screws or bolts, which is convenient for disassembly and assembly.

[0056] like Figure 3 and Figure 6 As shown, in some embodiments, the connecting section 211 is in the extension direction of the support rod 10 (such as Figure 6 On one side (as shown in the up and down direction) Figure 6The upper side shown in the figure has an avoidance groove 2111, that is, the avoidance groove 2111 can be set on the upper edge of the connecting section 211, so that the cable 200 can pass through the avoidance groove 2111 when it is active, thereby avoiding the cable 200, preventing the cable 200 from interfering with the connecting section 211 when subjected to external loads, and preventing the cable 200 from being scratched and damaged by the connecting section 211 when it is active, thereby improving the reliability of the support for the cable 200 and increasing the service life of the cable 200.

[0057] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, according to some embodiments of the present application, the support ear 21 further includes: a limiting plate 23, the limiting plate 23 can be connected to the support section 212 and the support rod 10 respectively, and a limiting cavity is defined between the limiting plate 23 and the support ear 21, and a portion of the roller 22 can be located in the limiting cavity, that is, a portion of the roller 22 can be located in the extension direction of the support ear 21 in the support rod 10 (such as Figure 2 On one side (as shown in the up and down direction) Figure 3 The cable 200 can pass through the limiting cavity, and the cable 200 can be supported on the roller 22. On the basis of ensuring that the cable 200 is in contact with the roller 22 and moves normally, the cable 200 can be limited to prevent the cable 200 from being separated from the roller 22, thereby improving the reliability of the support for the cable 200.

[0058] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments, the limiting plate 23 includes: a fixed section 231, a positioning section 232 and a limiting section 233. The fixed section 231 can be connected to the support rod 10, the positioning section 232 can be connected to the support section 212, the limiting section 233 can be arranged between the fixed section 231 and the positioning section 232, and the limiting section 233 can be connected to the fixed section 231 and the positioning section 232 respectively, that is, the limiting plate 23 can be a bent part, which is easy to process based on ensuring the structural strength of the limiting plate 23.

[0059] The limiting section 233 may be located in the extension direction of the support ear 21 in the support rod 10 (eg Figure 3 On one side (as shown in the up and down direction) Figure 3 The upper side shown in the figure) can limit the cable 200 in the limiting cavity, prevent the cable 200 from being separated from the roller 22, and improve the reliability of supporting the cable 200. The positioning section 232 can be parallel to the fixing section 231, which is based on ensuring that the limiting plate 23 can be connected to the support rod 10 and the support section 212 respectively, which is conducive to saving space and is easy to install.

[0060] like Figure 3 and Figure 7 As shown, in some embodiments, the fixing section 231 may have a socket 2311, and the socket 2311 may be penetrated by a fastener, that is, the fixing section 231 may be connected to the support rod 10 by a fastener such as a screw or a bolt, which is convenient for disassembly and assembly, and convenient for adjusting the position of the limit plate 23. One side of the positioning section 232 (such as Figure 7 The lower side) edge shown in the figure can have a positioning notch 2321, and the rotating shaft 50 can be plugged into the positioning notch 2321 to realize the positioning of the installation of the limit plate 23, facilitate the installation of the limit plate 23, and facilitate the connection between the positioning section 232 and the support section 212.

[0061] It can be understood that the rotating shaft 50 can be a fastener (for example, a bolt). Before the operator tightens the nut on the bolt, the positioning notch 2321 of the positioning section 232 can first be plugged into and matched with the rotating shaft 50, so as to realize the positioning of the limit plate 23, so as to facilitate the alignment of the socket 2311 of the fixed section 231 with the socket of the support rod 10. After the fixed section 231 is connected to the support rod 10 through the fastener, the operator can tighten the nut, which can realize the installation of the limit plate 23 and improve the stability of the installation of the limit plate 23.

[0062] like Figure 1 、 Figure 8 and Figure 9 As shown, the photovoltaic flexible bracket 1000 according to the embodiment of the present application includes a support structure 100 for the photovoltaic flexible bracket. By adopting the above-mentioned support structure 100, the tension loss of the cable 200 can be reduced, the utilization efficiency of the cable 200 can be improved, and at the same time, the force exerted by the cable 200 on the support structure 100 when subjected to external loads can be reduced, the service life of the photovoltaic flexible bracket 1000 can be improved, and the cost can be reduced.

[0063] In addition, by adopting the above-mentioned support structure 100, the photovoltaic flexible bracket 1000 can adapt to flexible bracket solutions with a large number of spans, longer cables 200 and a large number of connection points, and can improve the mechanical advantages of the photovoltaic flexible bracket 1000 and improve the economic advantages of the photovoltaic flexible bracket 1000.
