[0029] Example 1

[0030] See Figure 1 and Figure 2The buckling-resistant photovoltaic bracket disclosed in this utility model includes: a support part 1, a crossbeam 2, and a diagonal brace 3. The crossbeam 3 is connected to the top of the support part 1. The diagonal brace 3 includes a support rod core 31, filler material 32, and an outer sleeve 33. The support rod core 31 passes through the outer sleeve 33, and the filler material 32 fills the gap between the outer sleeve 33 and the support rod core 31. One end of the support rod core 31 is connected to the crossbeam 2, and the other end is connected to the support part 1. Regarding buckling resistance, the material of the diagonal brace 3 is changed from steel to a hybrid material structure. By increasing the stiffness of the diagonal brace 3, the buckling resistance of the photovoltaic bracket is improved. Specifically, setting the support rod core 31 is equivalent to internal reinforcement. The outer sleeve 33 is fitted over the support rod core 31, which is equivalent to using the outer sleeve 33 as a non-removable template. After the filler material 32 poured into the outer sleeve 33 solidifies, it increases the stiffness of the diagonal brace 3, thereby improving the buckling resistance of the diagonal brace 3.

[0031] See Figure 3 The upper end of the outer tube 33 is provided with an opening, and the lower end of the outer tube 33 is provided with a bottom wall 331. The purpose of this arrangement is that the outer tube 33 acts as a template that can be removed without disassembling. Therefore, the upper end of the outer tube 33 is provided with an opening to facilitate the filling material 32 to be poured in through this opening. The lower end of the outer tube 33 is provided with a bottom wall 331 to prevent the filling material 32 from flowing out from the lower end of the outer tube 33 before it has solidified.

[0032] See Figure 3 and Figure 4 The bottom wall 331 of the outer tube 33 has a hole 332. The two ends of the inner core 31 of the support rod have connecting ears 311. When assembling the diagonal brace 3, the inner core 31 of the support rod is placed into the outer tube 33, and then the connecting ears 311 are inserted through the hole 332 into the bottom wall 311. At this time, the connecting ears 311 also seal the hole 332 while passing through the hole 332. The advantage of this setting is that when the filler 32 is poured into the outer tube 33, the filler 32 can be prevented from leaking from the hole 332.

[0033] See Figure 2 and Figure 3 The outer surface of the inner core 31 of the support rod is provided with protrusions 312, so that after the filler 32 solidifies, it can fully engage with the protrusions 312 on the outer surface of the inner core 31 of the support rod. This setting serves two purposes: first, the protrusions 312 on the outer surface of the inner core 31 of the support rod acts as an anti-slip element, preventing the solidified filler 32 from sliding or rotating along the inner core of the support rod; second, when the inner core 31 of the support rod is subjected to axial pressure, the inner core 31 of the support rod can disperse and transfer this pressure to the filler 32 through the protrusions 312 distributed around its periphery, making full use of the more pressure-resistant characteristics of the filler 32, improving the compressive strength of the entire diagonal brace 3, and significantly increasing the critical value for buckling failure of the diagonal brace 3.

[0034] It should be noted that the outer tube 33 can be made of square tube, round tube or other materials that can serve as a template without disassembly; the main body of the inner core 31 of the support rod can be made of materials with good compressive strength such as shaped steel, angle steel or steel pipe, and the inner core 31 of the support rod is provided with connecting ears 311 at both ends. On this basis, it is even more preferable to use a rod with irregular protrusions on the periphery as the main body of the inner core 31 of the support rod; the filler 32 is made of non-shrink high-strength mortar or other polymer materials with good rigidity after solidification.

[0035] To further improve the buckling resistance of the photovoltaic support structure, the number of diagonal braces 3 is set to be greater than or equal to two, which can improve the wind resistance of the photovoltaic support structure in more directions and further improve the overall stability of the support structure.

[0036] It should be noted that the support component 1 includes a column 11 and a pile foundation 12, and the column 11 and the pile foundation 12 are connected by welding or clamps. The connecting lug 311 at one end of the diagonal brace 3 is connected to the crossbeam 2 by welding or bolts, the connecting lug 311 at the other end of the diagonal brace 3 is connected to the bottom of the column 11 by welding or bolts, and the top of the column 11 is connected to the crossbeam 2 by welding or bolts. This rigid connection method can ensure the connection stability between the various components of the support.

[0037] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
