[0043] As shown in Figure 1 , the C-shaped steel column 4 extends into the embedded channel steel 2 and is clamped and fixed through locking holes 10 uniformly distributed on the embedded channel steel 2. Figure 1 (b) is Figure 1 (a) a sectional view. Specifically, as shown in Figure 1 (b), bolt holes are provided on the barrel wall of the embedded channel steel 2, bolts are arranged in the bolt holes, and the embedded channel steel 2 is clamped and fixed with the bolts on the three contact surfaces of the C-shaped steel column 4.

[0046] Figure 4 As shown in Figure 4 , the fixed holes 13 are distributed on both sides of the rectangular protrusions 12, for locking the clamping of the fixed plates 11 to the front and rear C-shaped steel columns 4. As can be seen, since the two rectangular protrusions 12 are evenly distributed on the fixed plates 11, the fixed holes 13 are also evenly distributed on the fixed plates 11, so that the two fixed plates 11 are tightly clamped. The distribution of the fixed holes 13 on both sides of the rectangular protrusions 12 can not only connect the front and rear diagonal supports 7, but also ensure the stability of the column and the diagonal support connecting piece 6, preventing it from loosening under stress. The cuboid cavity is used to accommodate the C-shaped steel column 4, and the size of the cuboid cavity should be adapted to the size of the C-shaped steel column 4. As shown in Figure 4 (a), the two long strip-shaped fixed plates 11 are long and short, and the longer one is provided with a connecting hole 14. The fixed bolt passes through the fixed hole 13, and the tightening of the fixed bolt helps to improve the clamping force. Figure 4 (b) is (a) the bottom view of the long fixed plate 11, as can be seen, the fixed holes 13 are also evenly distributed on the fixed plates 11, so that the two fixed plates 11 are tightly clamped.

The longer one of the two fixed plates 11 is provided with a connecting hole 14, and the connecting hole 14 is distributed at both ends of the strip-shaped plate, for connecting the front and rear diagonal supports 7.

[0048] Figure 6As shown, the C-shaped steel column 4 is provided with bolt holes away from the top of the pile foundation 1, and the C-shaped steel column 4 is connected with the inclined beam 8 through bolts. The included angle between the C-shaped steel column 4 and the inclined beam 8 can be adjusted. Figure 6 (b) is Figure 6 The left view of (a).

[0049] As Figure 7 shown, the front and rear inclined supports 7 are respectively connected to the two ends of the inclined beam 8 of the photovoltaic support, and the connection mode can be bolt connection or hinging. Figure 7 (b) is Figure 7 the cross-sectional view of (a). The unopened wide surface of the inclined beam 8 is provided with bolt holes for fixedly connecting the inclined beam 8 and the inclined support 7.

[0050] As Figure 8 shown, the inclined beam 8 of the photovoltaic support is connected with the purlin 9 through the angle steel purlin support, and the purlin 9 is used for connecting with the photovoltaic panel.

[0051] As Figure 9 shown, a double-C-shaped steel photovoltaic support which can be adjusted according to the terrain comprises two front and rear embedded channel steels 2 fixed in a pile foundation 1, a column-to-column support 5 connecting the front and rear C-shaped steel columns 4, the front and rear C-shaped steel columns 4, a column and inclined support connecting piece 6, and front and rear inclined supports 7 respectively connected to the two ends of the inclined beam 8 of the photovoltaic support. The lattice column system formed by the front and rear C-shaped steel columns 4 and the column-to-column support 5 has the ability to bear greater load and cope with more complex working conditions, while reducing the amount of steel used; significantly improves the overall stability of the photovoltaic support system, effectively reduces the negative impact of natural factors such as earthquakes, winds, snowfall, etc. on the support, and ensures the stable operation of the system. The cross section of the C-shaped steel is in the shape of a "C", which makes it have significant advantages in bearing capacity, stability and economy. From the perspective of mechanical properties, C-shaped steel has excellent bearing capacity. Its cross-sectional design allows it to provide a larger cross-sectional area under the same weight, thereby enhancing its bending and compression resistance. In addition, the structure of the C-shaped steel can effectively disperse stress, reducing the possibility of local overload and improving the overall stability of the structure.
