[0002] Solar power generation is a clean and environmentally friendly energy source. It is simple, feasible, safe, reliable, and sustainable, requiring no fuel or rotating mechanical parts. Therefore, it is welcomed worldwide. Solar power systems, with their stable and reliable power supply and convenient installation, are increasingly widely used, gradually becoming a supplement and alternative to conventional electricity. Driven by the booming international photovoltaic market and guided by national policies, my country's photovoltaic industry has developed rapidly in recent years. Photovoltaic technology has improved significantly, gradually overcoming the obstacle of high power generation costs. It has been promoted and applied in building engineering and, as an important component of building-integrated solar power (BISP), has achieved significant benefits in energy-saving projects.

[0003] Solar photovoltaic (PV) power generation is a method of providing electricity by installing solar photovoltaic (PV) cell modules on specific supports to form PV arrays and utilizing PV grid-connected power generation technology. The cell array receives sunlight and generates direct current (DC). The current is output to a combiner box and connected in parallel with a current-limiting device. Then, multiple combiner boxes output the current to an inverter. Finally, the inverter converts the DC power into alternating current (AC) and transmits it to the grid or, after being boosted, connects it to the grid.

[0004] In high-altitude and cold regions, radiation is intense, there is abundant sunshine, large diurnal temperature range, and frequent strong winds. Traditional solar photovoltaic brackets are simply anchored to the ground or other flat surfaces, which is unsuitable for high-altitude and cold regions and is prone to tipping over in strong winds, resulting in damage to the solar photovoltaic panels.

[0035] Please see Figures 1 to 3 One embodiment of the solar photovoltaic mounting bracket includes a pile foundation 10, a bracket foundation 20, a column 30, and a bracket body 40.

[0036] The pile foundation 10 is anchored in the soil, and the top of the pile foundation 10 extends a certain distance above the ground. The pile foundation 10 is provided with a casting cavity 11, the opening of which penetrates the top of the pile foundation 10. During the construction process, a circular formwork can be inserted into the poured concrete to form the casting cavity 11.

[0037] The support foundation 20 is installed at the top of the pile foundation 10. The base 23 of the support foundation 20 is located outside the opening of the pouring cavity 11, and the anchoring cylinder 21 of the support foundation 20 extends into the pouring cavity 11 through the opening. Anchoring steel bars 22 are installed inside the anchoring cylinder 21, extending through the anchoring cylinder 21 into the pouring cavity 11. Then, concrete grout is poured into the pouring cavity 11, filling the anchoring cylinder 21. After the concrete solidifies, the anchoring steel bars 22 connect the pile foundation 10 and the support foundation 20, ensuring the anchoring strength of the support foundation 20. The base 23 has a certain distance from the top of the pile foundation 10 to allow for concrete filling, ensuring the bonding strength between the support foundation 20 and the pile foundation 10.

[0038] In one embodiment, the end of the anchoring rebar 22 located within the anchoring cylinder 21 is provided with a first extension structure 221, which is perpendicular to the axial direction of the pile foundation 10. The end of the anchoring rebar 22 located within the casting cavity 11 is provided with a second extension structure 222, which is also perpendicular to the axial direction of the pile foundation 10. The first extension structure 221 and the extension structures can increase the pull-out resistance of the support foundation 20, preventing the column 30 above the support foundation 20 from tilting. Specifically, the first extension structure 221 can be formed by perpendicularly connecting the rebar and the anchoring rebar 22, and the second extension structure 222 can be formed by bending the anchoring rebar 22.

[0039] The bottom end of the column 30 is fixed to the support base 20. In one embodiment, the base 23 of the support base 20 is provided with mounting holes 232, and the bottom end of the column 30 is provided with a flange 31, which fits into the base 23. The flange 31 has fixing holes 312 corresponding to the mounting holes 232, and screws 32 pass through the fixing holes 312 and are fixed in the mounting holes 232. The column 30 and the support base 20 are detachably connected by screws 32, which facilitates the maintenance and replacement of the solar photovoltaic panel 50 and the column 30. Specifically, the number of mounting holes 232 and fixing holes 312 is the same and there are multiple mounting holes 232 and fixing holes 312, which are evenly distributed along the circumferential direction.

[0040] In one embodiment, to prevent rainwater from corroding the screw 32 and causing it to become unscrewable, the solar photovoltaic mounting bracket also includes a waterproof cover 33. The waterproof cover 33 is installed on the column 30 and covers the screw 32, preventing rainwater from wetting the screw 32 and causing it to corrode. This improves the lifespan of the bracket and facilitates the replacement of the column 30.

[0041] Specifically, the waterproof cover 33 is made of rubber and includes a first half-shell 331 and a second half-shell 332. The first half-shell 331 and the second half-shell 332 are assembled to form a complete waterproof cover 33, which is easy to install onto the column 30. The gaps between the first half-shell 331 and the second half-shell 332 after assembly are heat-fused together. The column 30 has a grouted concrete structure, making it a reinforced concrete structure, which ensures the strength and rigidity of the column 30 while reducing the amount of material used.

[0042] A support body 40 is mounted on the top of the column 30 and is used to support the solar photovoltaic panel 50. In one embodiment, the support body 40 includes a support rod 41, a top rod 42, two connecting rods 43, and a support frame 44. The support rod 41 is mounted on the top of the column 30, and both ends of the support rod 41 pass through the sides of the column 30. The two connecting rods 43 are respectively hinged to the two ends of the support rod 41, and both connecting rods 43 are hinged to the support frame 44, which is used to support the solar photovoltaic panel 50. The top rod 42 is mounted on the top of the column 30, located between the two connecting rods 43, and connected to the middle of the support frame 44 to lift the support frame 44. The support frame 44 is located between the two columns 30, and the tops of the two columns 30 support the two ends of the support frame 44 respectively through the aforementioned connecting rods 43 and top rod 42.

[0043] Please refer to the following: Figure 4 and Figure 5 In one embodiment, the support frame 44 includes a front crossbeam 441, a rear crossbeam 442, and connecting beams 443. The front crossbeam 441 and the rear crossbeam 442 are arranged parallel to each other at intervals, and two connecting beams 443 respectively connect the two ends of the front crossbeam 441 and the rear crossbeam 442. Fixing blocks 444 for mounting solar photovoltaic panels 50 are installed on the front crossbeam 441 and the rear crossbeam 442.

[0044] Please refer to the following: Figure 6 Specifically, the fixing block 444 is L-shaped, and the bottom surface of the solar photovoltaic panel 50 is provided with a bearing ring 52. The bearing ring 52 is installed on the front crossbeam 441 or the rear crossbeam 442 by bolts, and the bearing ring 52 is also connected to the side of the fixing block 444 by bolts, which can ensure the installation strength of the bearing ring 52.

[0045] In one embodiment, a plurality of fixing blocks 444 are spaced apart on the front crossbeam 441 and the rear crossbeam 442. The two adjacent fixing blocks 444 face opposite directions. The opposite orientation of the fixing blocks 444 can make the two adjacent bearing rings 52 of the solar photovoltaic panel 50 move away from each other, which facilitates the installation of the bearing rings 52 and avoids mutual interference between the bearing rings 52. At the same time, it can provide enough space for the bolt connection between the solar photovoltaic panel 50 and the bearing ring 52.

[0046] The aforementioned solar photovoltaic mounting bracket has a pouring cavity 11 for the pile foundation 10. After the bracket foundation 20 is installed at the top of the pile foundation 10, the anchoring cylinder 21 of the bracket foundation 20 extends into the pouring cavity 11. Then, anchoring steel bars 22 are installed in the pouring cavity 11, passing through the anchoring cylinder 21 and extending into the pouring cavity 11. After grouting in the pouring cavity 11, the concrete grout poured in the pouring cavity 11 fills the anchoring cylinder 21, thus connecting the pile foundation 10 and the bracket foundation 20 with the anchoring steel bars 22. This ensures the anchoring strength of the bracket foundation 20, preventing the column 30 from tilting or even overturning in high-altitude and cold regions with strong winds, thus avoiding the overturning of the solar photovoltaic panel 50 and ensuring the safety of the solar photovoltaic panel 50.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
