Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "before," "after," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" covers the element following "comprising" or "including" and its equivalents, which does not exclude that the element preceding "comprising" or "including" may also include other elements.

[0029] Please refer to Figures 1 to 8 As shown, this utility model discloses a photovoltaic support including a column 10, a column top seat 20, a bearing seat 30, and a main shaft 40. The column top seat 20 is installed on the top of the column 10, the bearing seat 30 is installed on the top of the column top seat 20, and the main shaft 40 passes through the bearing seat 30.
[0030] Column 10 is made of H-beams, see [reference]. Figure 3 The column 10 includes a web 101 and two wing plates 102 vertically connected to both sides of the web 101. The web 101 is connected to the column top seat 20 via a first fastening assembly 50, thereby fixing the column top seat 20 to the top of the column 10. Specifically, the first fastening assembly 50 includes a first bolt 501 and a first nut 502, and the top of the web 101 is provided with a plurality of third mounting holes 1011 for the first bolt 501 to pass through.
[0031] Since the cross-sectional strength of column 10 is related to the net cross-sectional area, which is the cross-sectional area after deducting the mounting holes, the more mounting holes there are, the smaller the net cross-sectional area and the lower the cross-sectional strength. Since the wing plate 102 of column 10 rotates around the strong axis mainly for bending resistance, and the web plate 101 of column 10 rotates around the weak axis mainly for shear resistance, setting several third mounting holes 1011 in the web plate 101 can not only avoid opening holes in the wing plate 102, thus solving the problem of reduced bending strength of column 10, but also reduce the number of openings in the web plate 101, increasing the cross-sectional strength of column 10 and further enhancing the stability of column 10.
[0032] See Figures 1 to 5 The column top seat 20 includes a seat body 1 and a stop 2 connected to the seat body 1. The seat body 1 includes a mounting part 11, two connecting parts 12 connected to both sides of the mounting part 11, and two vertical parts 13 connected to the two connecting parts 12 and perpendicular to the mounting part 11. The bearing seat 30 is connected to the mounting part 11 through a second fastening assembly 60. In this embodiment, the two connecting parts 12 bend and extend from the mounting part 11 in a direction that approaches each other, so that the two vertical parts 13 approach each other and form a mounting gap 130. The web 101 of the column 10 is provided in the mounting gap 130 between the two vertical parts 13. In other words, the two vertical parts 13 clamp the web 101 of the column 10, so that the web 101 is subjected to uniform force on both sides and is not easily bent or deformed.
[0033] The mounting space 120, enclosed by the mounting part 11 and the two connecting parts 12, communicates with the mounting gap 130. This mounting space 120 is used to mount the second fastening assembly 60. (See also...) Figure 3 The second fastening assembly 60 includes a second bolt 601 and a second nut 602. During installation, the second bolt 601 is passed through the first mounting hole 110 of the mounting part 11 and the hole of the bearing seat 30 in sequence and connected to the second nut 602.
[0034] See Figure 4The mounting section 11 is provided with a plurality of first mounting holes 110, at least some of which are oblong holes. The vertical section 13 is provided with a plurality of second mounting holes 134 for the first bolt 501 to pass through, at least some of which are oblong holes. During on-site installation, the photovoltaic support pile foundation usually experiences deviations in height or horizontal direction, and the columns generally use profiles of uniform height. Therefore, the top of the column will have height or horizontal errors. By cooperating with the third mounting holes 1011 on the web plate 101, the position of the column top seat in the column height direction can be adjusted, thereby ensuring that the bearing seats on each column are at the same height, facilitating the subsequent installation of the main shaft. Through the oblong holes of the first mounting holes 110, the position of the bearing seats in the column horizontal direction can be adjusted, thereby ensuring that the bearing seats on each column are on the same axis, facilitating the installation of the main shaft. During installation, the first bolt 501 passes through the second mounting hole 134 of a vertical part 13, the third mounting hole 1011 of the web 101, and the second mounting hole 134 of another vertical part 13 in sequence, and is connected to the first nut 502.
[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, a plurality of second mounting holes 134 are arranged in two vertical rows, one row of which has oblong holes and the other row has round holes; a plurality of third mounting holes 1011 are also arranged in two vertical rows, one row of which has oblong holes and the other row has round holes. The round holes on the web 101 correspond to the oblong holes on the vertical portion 13, and vice versa. Through the cooperation of the oblong holes and round holes, the position of the photovoltaic bracket's top seat in the column height direction can be finely adjusted, thereby adjusting the height installation error. In other possible embodiments, both rows of second mounting holes 134 are oblong holes, and both rows of third mounting holes 1011 are round holes; or, both rows of second mounting holes 134 are round holes, and both rows of third mounting holes 1011 are oblong holes.
[0036] See Figures 4 to 6Each connecting portion 12 includes a first connecting portion 121 and a second connecting portion 122 connected to the first connecting portion 121. The two first connecting portions 121 are perpendicularly connected to both sides of the mounting portion 11, and the two second connecting portions 122 bend and extend from the first connecting portions 121 in a direction closer to each other. Specifically, there is a middle plane M between the two second connecting portions 122, and each second connecting portion 122 bends and extends from the first connecting portion 121 in a direction closer to the middle plane M. The vertical portion 13 is connected to the second connecting portion 122. In this invention, each connecting portion 12 extends a certain distance along the direction perpendicular to the mounting portion 11 before extending in a direction closer to each other, which increases the installation space 120 between the connecting portion 12 and the mounting portion 11, making it easier for installers to reach in and tighten bolts.
[0037] See Figure 6 The second connecting part 122 includes a first end 1221 and a second end 1222. The first end 1221 is connected to the first connecting part 121, and the second end 1222 is connected to the vertical part 13. The plane containing the first end 1221 and the second end 1222 forms an angle θ with the first connecting part 121.
[0038] In this embodiment, see Figure 6 The second connecting part 122 is a flat plate structure. The included angle θ formed between the second connecting part 122 and the first connecting part 121 is greater than 90° and less than 180°, that is, the second connecting part 122 is inclined relative to the first connecting part 121.
[0039] In another possible embodiment, the second connecting portion 122 is a flat plate structure, and the included angle θ formed between the second connecting portion 122 and the first connecting portion 121 is equal to 90°, that is, the second connecting portion 122 is perpendicular to the first connecting portion 121. In yet another possible embodiment, the second connecting portion 122 is an arc-shaped structure, and the included angle θ formed between the plane containing the first end 1221 and the second end 1222 and the first connecting portion 121 is greater than 90° and less than 180°.
[0040] See Figure 2 , Figure 4 and Figure 5Each vertical section 13 includes a main body 131 and two rolled edges 132 connected to both sides of the main body 131. Each rolled edge 132 extends from the main body 131 in a direction away from the installation space 130. The rolled edge 132 abuts against the inner side of the wing plate 102, which helps to improve the connection stability between the column top seat 20 and the column 10. During the manufacturing process, the two sides of the vertical section 13 are cut to form a piece, and then the piece is bent to form the rolled edge 132. During the cutting, a section is left uncut at the upper end of the vertical section 13, thereby forming two straight edges 133 on both sides of the main body 131. The straight edges 133 are closer to the connecting part 12 than the rolled edges 132. The straight edges 133 abut against the top of the wing plate 102, thereby improving the connection stability between the column top seat 20 and the column 10.
[0041] See Figure 5 and Figure 6 The base 1 is provided with reinforcing ribs 14, which are connected to the vertical part 13 and the connecting part 12. The reinforcing ribs 14 help to improve the structural strength of the base 1. In this embodiment, the reinforcing ribs 14 are fixed to the vertical part 13 and the connecting part 12 by welding.
[0042] The baffle 2 covers the opening of the mounting space 120 formed by the mounting part 11 and the two connecting parts 12, thus providing dust and rain protection. (See also...) Figure 5 The stop 2 includes a baffle 21 and an edge portion 22 connected to the baffle 21 and bent relative to the baffle 21. In some embodiments, the edge portion 22 of the stop 2 is fixedly connected to the base 1 by bolts for easy disassembly. In other possible embodiments, the edge portion 22 of the stop 2 is fixedly connected to the base 1 by welding.
