PREFERRED EMBODIMENT

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] like Figures 1-4 As shown, a photovoltaic support structure for a large-span grain silo includes a supporting steel frame installed on the top of the grain silo. The supporting steel frame provides stable fixing points for the entire photovoltaic support structure, ensuring the structural stability of the photovoltaic support structure.

[0030] A support frame 1 is provided on the support steel frame. Two sets of fixing modules for fixing photovoltaic panels 3 are slidably provided on the upper end surface of the support frame 1. Two sets of support modules connected to the support steel frame are slidably provided on the lower end of the support frame 1.

[0031] The support module includes a first height frame 9 slidably mounted on the lower end of the support frame 1, a second height frame 10 movably fitted to one side of the first height frame 9, both the first height frame 9 and the second height frame 10 being L-shaped, several sets of spaced limiting slots 11 opened on the side of the first height frame 9 near the second height frame 10, several sets of spaced limiting protrusions 12 set on the side of the second height frame 10 and interlocking with the limiting slots 11, a waist-shaped groove 13 penetrating between the first height frame 9 and the second height frame 10, and a fixing component 14 movably mounted inside the waist-shaped groove 13 for fixing the second height frame 10 and the limiting slots 11. The fixing component 14 includes bolts and nuts. When installing photovoltaic supports on the roof of a large-span grain silo, workers can adjust the first height frame. The staggered engagement length between height frame 9 and height frame 10 adjusts the support height, with a smaller range of adjustment spacing, which can accommodate slight slope or height difference changes. This is to better adapt to the needs of photovoltaic bracket installation on large-span grain silos. Furthermore, since the limiting slot 11 is opened on the surface of height frame 9 and does not penetrate it, height frame 9 has high strength, preventing deformation. The interlocking structure of multiple sets of limiting slots 11 and limiting protrusions 12 improves the stability of the connection between height frame 9 and height frame 10. Then, the clamping and fixing formed between the two by the fastener 14 allows them to be more tightly engaged, thereby further improving the stability of the connection between height frame 9 and height frame 10.

[0032] Provides fixed points for height adjustment to ensure the stability of the photovoltaic panel at different heights and to ensure the stability of the adjusted height position.

[0033] In this embodiment, specifically, the fixing module includes a moving seat 2 slidingly arranged on the upper end surface of the erecting frame body 1, and a limiting clamping plate 4 for fixing the photovoltaic panel 3 is arranged on the top of the moving seat 2. Through the sliding design of the moving seat 2, the photovoltaic panel 3 of different sizes can be adapted, the flexible installation and adjustment of the photovoltaic panel are realized, and the installation efficiency is improved.

[0034] In this embodiment, specifically, the inside of the erecting frame body 1 is provided with a partition plate 5, so that the erecting frame body 1 is divided into two parts. Limiting sliding grooves 6 for the movement of the fixing module and the supporting module are arranged on the upper and lower end surfaces of the erecting frame body 1. The design of the partition plate 5 and the limiting sliding grooves 6 ensures the independent movement of the fixing module and the supporting module, and improves the flexibility and stability of the structure.

[0035] In this embodiment, specifically, a first inner plate 7 is slidingly arranged at the inner bottom of the erecting frame body 1, and the first inner plate 7 is located between the erecting frame body 1 and the partition plate 5. A first screw rod 8 penetrating through the limiting sliding groove 6 arranged on the lower end surface of the erecting frame body 1 is arranged on the bottom of the first inner plate 7, and the first screw rod 8 is movably connected with a first height frame 9. The first inner plate 7 and the first screw rod 8 provide a flexible adjustment function. The staff can pull the first inner plate 7 according to the actual construction needs, so as to adjust the fixed position of the first height frame 9. A nut can be arranged on the first screw rod 8, so as to stably fix the first height frame 9 on the lower end surface of the erecting frame body 1.

[0036] In this embodiment, specifically, a limiting clamping groove 11 is arranged on the upper end surface of the erecting frame body 1, and a fixing hole 15 for fixing the supporting steel frame is arranged on the limiting clamping groove 11.

[0037] In this embodiment, specifically, a first clamping plate 16 and a second clamping plate 17 are arranged on the inner top of the erecting frame body 1 from top to bottom. A first rib plate 18 is arranged on the top of the end of the first clamping plate 16 close to each other, and the first rib plate 18 is connected with the top wall of the erecting frame body 1. A second rib plate 19 is arranged on the bottom of the end of the second clamping plate 17 close to each other, and the second rib plate 19 is connected with the top of the partition plate 5. The inside of the erecting frame body 1 is hollow. Since the limiting sliding grooves 6 are arranged on the upper and lower end surfaces of the erecting frame body 1, the overall strength of the erecting frame body 1 is weak. The first rib plate 18 arranged on the first clamping plate 16 supports the top wall of the erecting frame body 1, forming a I-shaped structure. The second rib plate 19, the second clamping plate 17 and the partition plate 5 also form a I-shaped structure, thereby further improving the overall strength and load capacity of the erecting frame body 1.

[0038] In this embodiment, specifically, a second inner plate 20 is slidingly arranged between the first clamping plate 16 and the second clamping plate 17. A second screw rod 21 penetrating through the limiting sliding groove 6 arranged on the upper end surface of the erecting frame body 1 is arranged on the top of the second inner plate 20, and the second screw rod 21 is movably connected with the moving seat 2. A nut can be arranged on the second screw rod 21, so as to stably fix the moving seat 2 on the upper end surface of the erecting frame body 1.

[0039] In this embodiment, specifically, a plurality of groups of positioning screw grooves 22 are symmetrically arranged on both sides of the frame body 1, the positioning screw grooves 22 are internally threadedly connected with positioning bolts 23 for extruding the second inner plate 20, further ensuring that the second inner plate 20 is not easy to deviate after being adjusted to a proper position, avoiding deviation when limiting the photovoltaic panel 3.

[0040] The above only discloses several specific embodiments of the present application, but the embodiments of the present application are not limited to this, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present application.
