[0037] A control rope 1, which passes through a plurality of rope loops B7, a rope guide assembly 9 on one side, a plurality of rope loops A2, and a rope guide assembly 9 on the other side in sequence. Both ends of the control rope 1 are also connected to a tensioning assembly 8. The tensioning assembly 8 is used to fix both ends of the control rope 1 and keep the control rope 1 in a taut state. After the control rope 1 is in a taut state, the fixing member fixes the control rope 1;

[0040] like Figure 1 、 2, 4 and 5, as a preferred embodiment of the present invention, the two connecting ears 5 are respectively fixed on both sides of the middle part of the photovoltaic substrate 3, and the connecting ears 5 are connected to the U-shaped frame 6 with damping rotation to improve the overall stability and avoid shaking of the photovoltaic substrate 3.

[0041] The rope loops A2 and B7 are respectively fixed at the center of the ends of the photovoltaic substrate 3. The cross-sections of the rope loops A2 and B7 are circular, which reduces friction between the control rope 1 and the rope loops A2 and B7, thereby improving the smoothness of adjustment. In addition, balls (not shown) can be placed inside the rope loops A2 and B7 as needed to further improve reliability.

[0042] The control rope 1 is preferably a steel wire rope, which has the required strength and is stable and reliable.

[0043] The bottom support 11 adopts an inverted U-shaped structure, and the assembly frame 10 adopts a convex structure. The bottom support 11 is slidably connected to the middle of the assembly frame 10. Side fixing grooves 30 are opened on both sides of the middle of the assembly frame 10. Fastening bolts A12 are installed on both sides of the bottom support 11 to abut and fix with the side fixing grooves 30, thereby improving the locking reliability and preventing the bottom support 11 from shaking.

A support wheel 32 is fixed at each end of the wheel axle 33. When the support wheel 32 abuts against the inner bottom of the upper wheel groove 29, the fastening bolt A12 corresponds horizontally to the side fixing groove 30, which facilitates reliable movement and adjustment of the bottom support 11.

[0046] When the multiple bottom supports 11 are sequentially abutted together, a certain distance is spaced between two adjacent photovoltaic substrates 3 , specifically greater than 0.5 cm, so that the multiple photovoltaic substrates 3 do not affect each other and can ensure consistent stability of installation.

[0047] like Figure 3As shown, as a preferred embodiment of the present invention, the tensioning assembly 8 includes a tensioning plate 19, and an end support block 21 is fixed at each end of the tensioning plate 19, and a forward and reverse screw rod 17 is rotatably installed between the two end support blocks 21, and a rotating cylinder A18 is fixed in the middle of the forward and reverse screw rod 17. A fixed block 16 is threadedly connected on both sides of the forward and reverse screw rod 17. When the forward and reverse screw rod 17 rotates, the two fixed blocks 16 approach or move away from each other; a tensioning block 20 is fixed on one side of the fixed block 16, and the tensioning block 20 is also slidably connected to the tensioning plate 19. A movable block 15 is also provided on the side of the fixed block 16 away from the tensioning block 20, and a fastening bolt B14 is threadedly connected on both sides of the movable block 15, and the fastening bolt B14 is also rotatably connected to the fixed block 16. The movable block 15 and the fixed block 16 are used together to fix the control rope 1.

[0048] Preferably, an anti-slip groove is further provided in the middle of the side where the movable block 15 and the fixed block 16 are close to each other, and the anti-slip grooves of the movable block 15 and the fixed block 16 cooperate to fix the control rope 1.

[0049] During use, first tighten the two ends of the control rope 1, then rotate the fastening bolt B14, the movable block 15 abuts against the fixed block 16, thereby fixing the control rope 1, and then operate the rotating cylinder A18 to rotate the forward and reverse screw rods 17 to control the two fixed blocks 16 to move closer to or away from each other, thereby tightening the control rope 1, meeting the control rope 1's support requirements for the photovoltaic substrate 3 and ensuring its overall stability.

[0050] like Figure 4 and 6 As shown, as a preferred embodiment of the present invention, the rope guide assembly 9 includes a slider 24 that is anti-slip and slidingly connected to a lower sliding groove 31 opened on the lower side of the assembly frame 10, and the lower side of the slider 24 is also slidably connected to the bottom of the assembly frame 10. The lower side of the slider 24 is installed with a fastening bolt D27 for locking it on the assembly frame 10; the bottom of the slider 24 is fixed with a pipe support 26, and the inner side of the pipe support 26 is slidably provided with a guide tube 22, and the guide tube 22 is also fixed with an anti-torsion edge 23 that is slidably connected to the pipe support 26, and the pipe support 26 is also installed with a fastening bolt C25 for locking the guide tube 22.

[0051] Preferably, the guide tube 22 is arranged perpendicular to the assembly frame 10, so that the guide tube 22 conforms to the path through which the control rope 1 passes, and the overall structure is stable and reliable.

[0052] Preferably, the middle parts of both sides of the slider 24 are arc-shaped concave structures, forming a structure for preventing slippage and sliding with the lower sliding groove 31. A fastening bolt D27 is provided at each of the four lower corners of the slider 24 to ensure the stability of the adjustment lock.

[0053] Preferably, the two rope guiding assemblies 9 correspond to the middle of the photovoltaic substrate 3 at both ends respectively, so as to ensure the reliability of guiding the control rope 1.

[0054] During application, the position of the slider 24 can be adjusted as needed, that is, the position of the slider 24 can be flexibly adjusted according to the number of selected photovoltaic substrates 3; according to the adjustment angle, the fastening bolt C25 can also be loosened to adjust the position of the guide tube 22, so that the guide tube 22 is more adaptable and the force is reduced; the anti-twist edge 23 can prevent the guide tube 22 from twisting, so that the guide tube 22 can reliably guide the control rope 1, and at the same time enable the adjustment component 13 to stably drive the control rope 1 to move.

[0055] like Figure 6-8 As shown, as a preferred embodiment of the present invention, the adjustment assembly 13 includes a rotating cylinder B35 rotatably mounted on the end of the guide tube 22, and the inner side of the guide tube 22 is also provided with a threaded cylinder 40 fixedly connected to the rotating cylinder B35, and the inner side of the threaded cylinder 40 is threadedly connected to an adjustment block 39, the control rope 1 passes through the adjustment block 39, and the control rope 1 is fixedly connected to the adjustment block 39, and the inner side of the guide tube 22 is also fixed with an anti-torsion rod 38 slidingly connected to the adjustment block 39.

[0056] Preferably, the anti-torsion rod 38 adopts an L-shaped structure, one branch of the anti-torsion rod 38 is vertically fixedly connected to the inner wall of the guide tube 22, and the other branch of the anti-torsion rod 38 is parallel to the inner wall of the guide tube 22 and is slidingly connected to the anti-torsion rod 38. The length of the anti-torsion rod 38 can be arranged as needed to meet the requirements for anti-torsion support of the adjustment block 39.

[0057] Preferably, anti-slip ridges 36 are evenly distributed on the outer side of the rotating cylinder B35 to facilitate twisting of the rotating cylinder B35 and reliable operation.

[0058] Preferably, an auxiliary ring 41 is rotatably mounted on the end of the rotating drum B35 away from the rope guide assembly 9. This prevents the control rope 1 from being affected during rotation of the rotating drum B35, thereby improving operational reliability. Multiple guide wheels 37 are circumferentially mounted on the end of the guide tube 22 and on the inner side of the auxiliary ring 41 to guide the control rope 1, improving smoothness and preventing friction.

[0059] During use, after the control rope 1 is in a taut state and fixed by the fixing part, the threaded cylinder 40 is driven to rotate by rotating the rotating cylinder B35. The threaded connection characteristics of the threaded cylinder 40 and the adjustment block 39 are utilized to drive the control rope 1 to move. As a result, as the control rope 1 on one side of the assembly frame 10 contracts, the control rope 1 on the other side is released, thereby achieving the purpose of conveniently adjusting the angle of the photovoltaic substrate 3.

By cooperating with the fastening bolt E42 and the fastening plate, the control rope 1 can be firmly fixed to the inner wall of the guide tube 22 and the movement of the control rope 1 can be restricted.

[0061] The above embodiment of the present invention provides a convenient adjustable photovoltaic bracket, the working principle of which is as follows:

[0062] Multiple bottom supports 11 are supported by an assembly frame 10, and a U-shaped frame 6 is fixed on each bottom support 11. Two connecting ears 5 are rotatably installed in the middle of the U-shaped frame 6, and the photovoltaic substrate 3 is fixed across the two connecting ears 5 to achieve stable support for the photovoltaic panel 4.

[0063] The control rope 1 passes through the rope loops B7, the rope guide assembly 9 on one side, the rope loops A2, and the rope guide assembly 9 on the other side. The tensioning assembly 8 secures both ends of the control rope 1 and keeps it in a taut state. The fixing parts ensure the firmness of the control rope 1.

[0064] The rope guide assembly 9 includes components such as a slider 24, a tube support 26, and a guide tube 22, allowing the position to be flexibly adjusted as needed.

[0065] Adjustment assembly 13, through the coordination of rotating cylinder B35, threaded cylinder 40, adjustment block 39, and anti-twist rod 38, drives control rope 1 to move, thereby adjusting the angle of photovoltaic substrate 3. During adjustment, rotating cylinder B35 rotates threaded cylinder 40, which, utilizing the threaded connection, moves adjustment block 39, achieving the purpose of adjusting the tilt angle of photovoltaic substrate 3.

[0066] In summary, the present invention provides an integrated, highly flexible and conveniently adjustable photovoltaic bracket solution, which not only realizes the simultaneous and stable installation of multiple photovoltaic panels 4, but also can efficiently adjust the angle, thereby improving the reliability and operational convenience of the overall system.
