An inclined beam 4 is fixedly connected to the upper surface of the rod 10. Four horizontal purlins 6 are fixedly installed on the upper surface of each of the inclined beams 4. A photovoltaic panel 5 is fixedly installed on the upper surface of the four horizontal purlins 6. Front supports 7 and rear supports 8 are fixedly installed on the front and rear sides of the lower surface of the inclined beams 4, respectively. Front columns 12 and rear columns 11 are fixedly installed on the front and rear sides of the lower surface of the inclined beams 4, respectively.

A connecting column 313 is integrally formed between the opposite sides of the two semicircular blocks 311. The front and rear sides of the top semicircular block 311 are integrally formed with mounting plates 315 for easy installation. The mounting plates 315 facilitate the fixing of the rear column 11 and the front column 12. The precast pipe pile foundation 1 adopts a prestressed concrete pipe pile foundation with a diameter of 400mm and a pile length of 10m. The fixed inclination angle of the inclined beam 4 is 35°. The crossbeam purlin 6, the front support 7, and the rear support 8 are all Z-shaped. The front column 12, the rear column 11, the front support 7, the rear support 8, the inclined beam 4, and the crossbeam purlin 6 are made of cold-formed thin-walled steel of Q235B, Q355B, Q420B, S250GD, S350GD, and S450GD steel, respectively.

[0033] During the on-site installation of the photovoltaic support system, the precast pipe pile foundation 1 is installed on the water in the canal, with the pile body protruding about 3-5m above the water surface and extending 5m below the ground. The insert 9 is installed on the upper surface of the precast pipe pile foundation 1 using bolts. First, the front support 7, rear support 8, front column 12, and rear column 11 are installed on the lower surface of the inclined beam 4 using screws. Then, the crossbeam purlin 6 is installed and fixed to the inclined beam 4 using screws. Next, the photovoltaic panel 5 is installed on the upper surface of the crossbeam purlin 6 and fixed with screws. Finally, the left clamp 31 and right clamp 32 are fitted onto the left and right sides of the precast pipe pile foundation 1, so that the arc-shaped insert 314...

Both the front column 12 and the rear column 11 are L-shaped, which facilitates the installation of the inclined beam 4, the front column 12, and the rear column 11.

[0037] By setting four support points at the bottom of the inclined beam 4—front support 7, rear support 8, front column 12, and rear column 11—the deformation of the inclined beam 4 is smaller, stress concentration is avoided, and it is more convenient to use.

[0038] like Figure 4 , Figure 9As shown, the cross-section of the insert 9 is T-shaped, and a positioning groove 17 is provided on the lower surface of the inner cavity of the insert 9. A positioning block 14 is integrally formed on the lower surface of the insert rod 10. The outer side of the positioning block 14 is engaged with the inner cavity of the positioning groove 17. Both the positioning groove 17 and the positioning block 14 are stepped.

[0039] The positioning groove 17 and the positioning block 14 are engaged to position the insertion rod 10, thereby positioning and installing the photovoltaic bracket and ensuring the connection quality between the pipe pile foundation and the photovoltaic bracket.

[0040] like Figure 10 As shown, the outer surfaces of the left clamp 31 and the right clamp 32 are coated with an anti-corrosion layer 33, which is a hot-dip galvanized anti-corrosion layer with a thickness of ≥65μm.

[0041] By setting the anti-corrosion layer 33, the left clamp 31 and the right clamp 32 can be protected against corrosion, thus extending their service life.

[0042] like Figure 4 , Figure 10 As shown, slots 13 are provided on both the left and right sides of the upper surface of the protrusion 2, and an arc-shaped insert 314 is integrally formed on the lower surface of the bottom semicircular block 311. The outer side of the arc-shaped insert 314 is engaged with the inner cavity of the slot 13, and the cross section of the arc-shaped insert 314 is triangular.

[0043] The slot 13 and the arc-shaped insert 314 engage to position the bottom semicircular block 311, thereby assisting in the installation of the double clamp 3.

[0044] like Figures 1-12 As shown, connecting plates 312 are integrally formed on the front and rear sides of the bottom semicircular block 311, and the connecting plates 312 are L-shaped. A semicircular groove 316 is provided on the upper surface of the connecting plate 312, and the inner cavity of the semicircular groove 316 is inserted into the bottom end of the rear column 11.

[0045] The connecting plate 312 facilitates the installation of the front support 7 and the rear support 8, while the semi-circular groove 316 can limit the movement of the front column 12 and the rear column 11.

[0046] The working principle of this utility model is as follows: All structural components are prefabricated in the factory and installed on site. When installing the photovoltaic support on site, the prefabricated pipe pile foundation 1 is installed on the water in the canal, with the pile body protruding about 3-5m above the water surface and extending 5m below the ground. The insert 9 is installed on the upper surface of the prefabricated pipe pile foundation 1 with bolts. First, the front support 7, rear support 8, front column 12, and rear column 11 are installed on the lower surface of the inclined beam 4 with screws. Then, the positioning blocks 15 at the bottom of the four crossbeam purlins 6 are inserted into the positioning grooves 16 opened on the upper surface of the inclined beam 4. The crossbeam purlins 6 and the inclined beam 4 are installed and fixed with screws. Then, the photovoltaic panel 5 is installed on the upper surface of the crossbeam purlins 6 and fixed with screws. The positioning blocks 15 and positioning grooves 16 are used to assist in the positioning of the photovoltaic panel 5. Then, the left clamp 31 and right clamp 32 are put on the left and right sides of the prefabricated pipe pile foundation 1, so that the arc-shaped insert 314 is stuck on the top of the protrusion 2. The inner cavity of slot 13 is filled, and finally the insertion rod 10 at the bottom of the inclined beam 4 is inserted into the insertion cylinder 9, so that the positioning block 14 and the positioning groove 17 are engaged, which facilitates the positioning and installation of the photovoltaic bracket and ensures the connection quality between the pipe pile foundation and the photovoltaic bracket. The left clamp 31 and the right clamp 32 are fixed by bolts and nuts, and the front support 7, the rear support 8 and the two connecting plates 312 are fixed by screws. The on-site installation of the photovoltaic bracket can be completed. The components are assembled by fixing them with screws, which can reduce on-site welding, make the installation more convenient, and make the construction and installation faster and more convenient, shorten the construction period and improve the installation efficiency. Four support points are set at the bottom of the inclined beam 4: front support 7, rear support 8, front column 12 and rear column 11. The deformation of the inclined beam 4 is small, stress concentration is avoided, and it is more convenient to use. The anti-corrosion layer 33 can play a role in preventing corrosion of the left clamp 31 and the right clamp 32, extending their service life.

[0047] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
