[0037] like Figure 1 As shown, this embodiment provides a photovoltaic system, which includes a photovoltaic panel 50, a photovoltaic bracket, and an angle adjustment device. The photovoltaic panel 50 is supported by the photovoltaic bracket, and the angle adjustment device is disposed between connectors in the photovoltaic bracket, allowing the angle between the two connectors to be adjusted, thereby improving the adaptability of the photovoltaic bracket and meeting the installation requirements of the photovoltaic panel 50.

[0038] See Figure 3-4 The angle adjustment device of this embodiment specifically includes a first gear 61, a second gear 62, and a limiting gear ring 63. The first gear 61 is fixedly connected to the first connecting member, and the second gear 62 is fixedly connected to the second connecting member. The first gear 61 and the second gear 62 are coaxially arranged in parallel. The limiting gear ring is sleeved on the outer circumference of the first gear 61 and the second gear 62, and the limiting gear ring 63 meshes with both the first gear 61 and the second gear 62 to limit relative rotation of the first gear 61 and the second gear 62.

[0039] When using the angle adjustment device of this embodiment to adjust the angle of the first and second connectors, the first gear 61 and / or the second gear 62 are first moved out of the limiting gear ring 63; secondly, the first gear 61 and the second gear 62 are controlled to rotate relative to each other so that the angle between the first and second connectors meets the requirements; finally, the limiting gear ring 63 is mounted on the outer periphery of the first and second gears 61 and 62, preventing the first and second gears 61 and 62 from rotating relative to each other, thereby ensuring that the angle between the first and second connectors remains fixed. This angle adjustment device has a simple structure and is easy to assemble and disassemble. It can quickly adjust the angle between the two connectors, making the photovoltaic bracket more adaptable.

[0040] The angle adjustment device of this embodiment also includes a limiting claw 64, which specifically includes a first claw portion 64a and a second claw portion 64b. The first claw portion 64a cooperates with the second claw portion 64b to clamp the first connecting member and the second connecting member to limit the first connecting member and the second connecting member from moving axially away from the limiting gear ring 63, thereby preventing the first gear 61 and the second gear 62 from axially disengaging from the limiting gear ring 63.

[0041] In this embodiment, the first claw portion 64a and the second claw portion 64b form a U-shape. A connecting sleeve 64c is provided on the first claw portion 64a so that the first claw portion 64a is fixed to the first connecting member, and the second claw portion 64b abuts against the side wall of the second connecting member away from the first connecting member. The structure of the limiting claw 64 is simple and easy to assemble.

[0048] The detachable connection mode of this embodiment can be selected as follows Figure 4The illustrated boss 75 and groove 65 are configured as a mosaic structure, for example, with bosses 75 provided on the corresponding sleeve and grooves 65 provided on the corresponding gear. Both bosses 75 and grooves 65 are non-rotating in shape to restrict relative rotation. Some embodiments may also utilize bolts or snaps for detachable connection, which is not described in detail in this embodiment.

[0049] See Figure 5 In this embodiment, the cross-section of the longitudinal beam 40 is preferably I-shaped. Both sides of the longitudinal beam 40 have a groove structure to accommodate the edges of the photovoltaic panel 50, ensuring that the photovoltaic panel 50 can be stably installed between two adjacent longitudinal beams 40. A connecting assembly is preferably provided between the longitudinal beam 40 and the support rod 30. The connecting assembly includes an upper connecting member 80, a lower connecting member 81, and a supporting member 82. The upper connecting member 80 and the lower connecting member 81 are both channel-shaped. The opening of the upper connecting member 80 faces upward, while the opening of the lower connecting member 81 faces downward. The bottom of the upper connecting member 80 and the top of the lower connecting member 81 are connected by bolts for easy assembly. The number of bolts is preferably one, so that the upper connecting member 80 can rotate relative to the lower connecting member 81 at an appropriate angle with the bolt as the central axis. The support member 82 is disposed in the opening of the upper connector 80, and bolts are passed through the support member 82 to connect to the two side walls of the upper connector 80 for easy assembly. The number of bolts at this location is preferably one, which can adjust the support member 82 to a suitable swing angle relative to the upper connector 80 in a plane parallel to the two side walls.

[0050] The tenon structure 83 formed on the top of the support member 82 of this embodiment is combined with the mortise structure formed on the bottom of the longitudinal beam 40 for easy assembly. The tenon structure 83 is preferably designed as a T-shape, so that the support member 82 and the longitudinal beam 40 have a large contact area to ensure a firm connection between the two.

[0051] In the photovoltaic system of this embodiment, the photovoltaic support specifically includes two pipe piles 10, a total of eight diagonal rods 20 on the two pipe piles 10, a total of eight support rods 30 connecting the diagonal rods 20, and five parallel longitudinal beams 40. Four longitudinal rows of photovoltaic panels 50 can be set between adjacent longitudinal beams 40. The corresponding angles between the pipe piles 10 and the diagonal rods 20, between the intersecting diagonal rods 20, and between the diagonal rods 20 and the support rods 30 can all be adjusted by an angle adjustment device; the relative positions between the support rods 30 and the longitudinal beams 40 are adjusted by a connecting assembly. On the one hand, this photovoltaic support can support a large number of photovoltaic panels 50 with a simple structure, eliminating the welding process, facilitating disassembly and assembly, and reducing costs. On the other hand, the various connecting parts can be flexibly adjusted, making the photovoltaic support more adaptable to meet the various installation requirements of the photovoltaic panels 50.

[0052] See Figure 6 In particular, for at least two groups of photovoltaic brackets installed in parallel, two adjacent groups of photovoltaic brackets can share a single longitudinal beam 40. Specifically, from left to right, the fifth longitudinal beam 40 of the first group of photovoltaic brackets can be shared with the first longitudinal beam 40 of the second group of photovoltaic brackets, further reducing the material used in the photovoltaic brackets and saving costs.
