Description

[0002] With the rapid development of photovoltaic power station construction, the available land resources are becoming less and less, and it is necessary to explore undeveloped areas for the construction of photovoltaic power stations. Traditional photovoltaic brackets have high requirements for the installation environment and cannot be installed in harsh environments. Traditional photovoltaic brackets include pipe piles and steel frames. Pipe piles are used as the supporting structure of the steel frame, and steel strands are connected to the steel frame for installing photovoltaic panels. However, due to structural limitations, the pipe piles will be subjected to large horizontal forces from the steel strands, and the embedding conditions of the installation position of the pipe piles are poor, which will cause the pipe piles to be subjected to large bending moments. Under long-term use, multiple pipe piles will be deformed, and the pipe piles will have independent horizontal displacements, which will easily lead to damage to the pipe piles, resulting in poor structural stability of the photovoltaic bracket, thereby affecting the installation stability of the photovoltaic panel.

[0034] The utility model provides a photovoltaic bracket.

[0035] In one embodiment of the present invention, Figures 1 to 7 As shown, the photovoltaic support includes a pipe pile 10, a beam 11 and a steel frame structure 20; a plurality of pipe piles 10 are provided, and the plurality of pipe piles 10 are placed at intervals to form at least two columns of base groups, and each base group includes at least two pipe piles 10; a beam 11 is provided corresponding to a base group, and each beam 11 is connected to at least two pipe piles 10; the steel frame structure 20 is provided above any beam 11, and the steel frame structure 20 is connected to multiple beams 11, and the steel frame structure 20 is used to connect steel strands 30, and the steel strands 30 are used for photovoltaic panel installation.

[0036] Related technologies show that there are multiple pipe piles 10 in a traditional photovoltaic bracket. Some of the pipe piles 10 are inserted into the ground or in positions with poor embedding conditions, and some of the pipe piles 10 are connected by a crossbeam 11. There are height differences between the pipe piles 10, and the intervals between adjacent pipe piles 10 are relatively far. When the photovoltaic bracket is subjected to horizontal loads for a long time, the pipe piles 10 at different positions are subjected to different horizontal forces, resulting in different displacements and deformation degrees of each pipe pile 10, causing damage to the pipe piles 10, which will affect the stability of the steel frame structure 20 above the pipe piles 10, thereby causing the steel frame structure 20 to deform, causing the steel strands 30 connected to the steel frame structure 20 to loosen or tighten, which will affect the installation of the photovoltaic panels and reduce the installation stability of the photovoltaic panels.

[0037] In the technical solution of the utility model, a plurality of pipe piles 10 are provided to form at least two rows of base groups. The two rows of base groups can be arranged flush or at an angle. At least two pipe piles 10 are arranged in each base group. All the pipe piles 10 in each base group are connected to a cross beam 11. A steel frame structure 20 is provided on the cross beam 11. The steel frame structure 20 is connected to a plurality of cross beams 11. Both ends of the steel strand 30 are connected to the steel frame structure 20. With the support of the steel frame structure 20 on both sides, the photovoltaic panels can be installed on the steel strand 30. With such an arrangement, when the pipe pile 10 is displaced by a horizontal force, due to the action of the cross beam 11, all the pipe piles 10 in the base group will be displaced together, and the multiple pipe piles 10 will not be displaced relative to each other, so the horizontal force can be evenly distributed to the multiple pipe piles 10. The cross beam 11 here can not only transmit and coordinate the horizontal force on the pipe piles 10, but also bear part of the bending moment on the top of the pipe pile 10, so as to avoid a certain pipe pile 10 being displaced due to uneven horizontal force, and the cross beam 11 can help multiple pipe piles 10 share the bending moment they are subjected to, so as to prevent the pipe piles 10 from being deformed or damaged due to excessive bending moment, thereby improving the service life of the pipe piles 10, thereby increasing the overall structural stability of the photovoltaic bracket and the installation stability of the photovoltaic panel.

[0038] Furthermore, the number of base groups may be three, four, five or six but not limited thereto. Each time a base group is formed, a crossbeam 11 is required to connect all the pipe piles 10 in the base group together, wherein the crossbeam 11 may be an I-beam, an H-steel, a channel steel or other types of steel, etc. The length of the main rod body 21 is determined according to the installation position. The main rod body 21 may be a rod formed by welding multiple rod segments together, or it may be a complete rod. When the two base groups are arranged at an angle, the two base groups may be two rows of spaced base groups, or they may share a pipe pile 10 as the initial pipe pile 10, and then place other pipe piles 10 at two different angles of the initial pipe pile 10, so that the two base groups are arranged at an angle. In the embodiment in which a pipe pile 10 is shared as the initial pipe pile 10, the two base groups also share a main rod body 21.

[0039] In one embodiment, the steel frame structure 20 includes a plurality of main rod bodies 21. At least two main rod bodies 21 are provided on a cross beam 11, and the two main rod bodies 21 are respectively provided on the upper sides of the first and last pipe piles 10. One end of the two main rod bodies 21 is connected to the cross beam 11, and the other ends of the two main rod bodies 21 are connected. The main rod bodies 21 are used to connect the steel strands 30.

[0040] Specifically, the number of pipe piles 10 in a base group can be two, three, four or five but not limited thereto. In the present embodiment, the number of pipe piles 10 in a base group is three, and the three pipe piles 10 are placed in sequence. A main pole body 21 is provided on the first and third pipe piles 10, and the main pole body 21 is welded and connected to the cross beam 11 on the pipe pile 10. A metal structure is provided on the upper end of the pipe pile 10, and the pipe pile 10 is welded and connected to the cross beam 11. The cross beam 11 and the two main pole bodies 21 are triangular in shape. The two main pole bodies 21 are inclined, and the upper end of the main pole body 21 at the tail end is connected to the steel strand 30. Such an arrangement can meet the installation requirements of photovoltaic panels. The main pole body 21 is connected to the pipe pile 10 through the cross beam 11. The cross beam 11 can share the bending moment transmitted to the pipe pile 10, reduce the bending moment received by the pipe pile 10, increase the service life of the pipe pile 10, and enhance the structural stiffness of the photovoltaic bracket. In some other embodiments, the steel frame structure includes multiple main poles, one of which is provided in a base group, is welded to the crossbeam, and is vertically arranged on the upper side of the pipe pile, and is used to connect the steel strands.

[0041] In one embodiment, the steel frame structure 20 further includes a connecting rod 22 . The connecting rod 22 is disposed on one side of the steel frame structure 20 . Two ends of the connecting rod 22 are respectively connected to a main rod body 21 on two adjacent beams 11 .

[0042] Specifically, one of the main rod bodies 21 on the two cross beams 11 is connected together by a connecting rod 22, that is, two main rod bodies 21 connected with steel strands 30 are connected together. Such a setting can ensure that there will not be too much deviation between the two main rod bodies 21. The connecting rod 22 is used to connect the ends of the two main rod bodies 21 to ensure the normal installation of the two steel strands 30, thereby ensuring the installation stability of the photovoltaic panel. When one of the main rod bodies 21 is displaced to a certain extent, the other main rod body 21 can provide a certain pulling force to prevent the displacement from occurring, thereby further ensuring that the steel strands 30 will not spread out. In some other embodiments, the connecting rod is used to connect two adjacent cross beams.

[0043] In one embodiment, a plurality of connecting rods 22 are provided, and at least two connecting rods 22 are cross-arranged.

[0044] Specifically, in this embodiment, at least four connecting rods 22 are provided, two connecting rods 22 are cross-arranged, and a connecting rod 22 is provided at the upper end and the lower end of the two connecting rods 22, respectively. The two main rod bodies 21 are connected together by four connecting rods 22. Such an arrangement can cross-tighten the main rod bodies 21 at both ends, further avoiding deformation or displacement of the main rod bodies 21, thereby not causing the relative positions of the two steel strands 30 to change, and the installation stability of the steel strands 30 will also be improved, further ensuring the stable installation of the photovoltaic panel. In some other embodiments, multiple connecting rods are provided, and in the height direction, the multiple connecting rods are spaced apart from each other.

[0045] In one embodiment, the steel frame structure 20 further includes an intermediate rod 23 , and an intermediate rod 23 is provided corresponding to one cross beam 11 . On one cross beam 11 , one end of the intermediate rod 23 is connected to the cross beam 11 , and the other end is connected to the middle position of one of the main rod bodies 21 .

[0046] Specifically, an intermediate rod 23 is added on the upper side of the cross beam 11, and one intermediate rod 23 is provided for each cross beam 11. One end of the intermediate rod 23 is welded to the cross beam 11, and the other end is hinged or welded to the main rod body 21 connected to the steel strand 30. This arrangement can increase the support for the main rod body 21 and further ensure the overall structural stability of the photovoltaic bracket. In some other embodiments, one end of the intermediate rod is connected to the connection of the two main rod bodies, and the other end of the intermediate rod is connected to the cross beam.

[0047] In one embodiment, the steel frame structure 20 includes a plurality of tie rods 24 and struts 25. On a crossbeam 11, a plurality of tie rods 24 are spaced apart along the height direction, and the two ends of the tie rods 24 are respectively connected to the two main rod bodies 21. In the height direction, a strut 25 is provided between any two adjacent tie rods 24, and the two ends of the strut 25 are respectively connected to the two main rod bodies 21, and the tie rods 24 are arranged at an angle.

[0048] Specifically, at least two tie rods 24 are provided between the two main rod bodies 21. In this embodiment, the heights of the two main rod bodies 21 are different. One tie rod 24 is connected to the upper ends of the two main rod bodies 21, and the other tie rod 24 is connected to the lower end of one main rod body 21 and the other main rod body 21. The two tie rods 24 are arranged at intervals from each other, and both tie rods 24 are arranged obliquely relative to the main rod bodies 21. In the height direction, a support rod 25 is provided between the two tie rods 24. The support rod 25 is placed horizontally and is used to connect the two main rod bodies 21. The tie rod 24 and the support rod 25 are arranged horizontally and are used to connect the two main rod bodies 21. The main rod body 21 is welded or hinged. In this way, the tension is shared by the tie rod 24, and the pressure is shared by the support rod 25. This can not only increase the connection stability between the two main rod bodies 21, but also increase the rigidity of the steel frame structure 20, and can set the steel frame structure 20 at a higher position, so as to meet the installation of photovoltaic panels in a higher clearance environment, and prevent the two main rod bodies 21 from relative displacement; further, when multiple tie rods 24 are provided between the two main rod bodies 21, the support rod 25 can be provided between any two adjacent tie rods 24. In some other embodiments, the steel frame structure includes multiple tie rods and support rods. On a crossbeam 11, one main rod body is correspondingly provided with a tie rod, one end of the tie rod is connected to the upper end of the main rod body, and the other end is connected to the crossbeam. The upper end of the main rod body is used to connect the upper ends of the two main rod bodies, and the support rod is used to connect the two main rod bodies.

[0049] In one embodiment, a plurality of support rods 25 are provided. On a crossbeam 11 , the plurality of support rods 25 are spaced apart in the height direction, and a pull rod 24 is provided between any two support rods 25 .

[0050] Specifically, on a beam 11, a plurality of tie rods 24 are provided between two main pole bodies 21, and a strut 25 is provided between any two adjacent tie rods 24. With this arrangement, for a high clearance environment, the overall height of the steel frame structure 20 can be increased by lengthening the height of the main pole body 21 or adding more tie rods 24 and struts 25. In this way, there is no need to increase the size in the width direction, and the photovoltaic bracket can be erected in a smaller installation space. Compared with the form of extending the length of the main pole body 21, a plurality of tie rods 24 and struts 25 are provided and assembled in combination. This form can increase the rigidity of the steel frame structure 20, reduce the possibility of deformation of the main pole body 21, and increase the service life of the steel frame structure 20, making it less prone to damage.

[0051] In one embodiment, the steel frame structure 20 includes a plurality of support rods 26. On a crossbeam 11, both ends of at least one support rod 26 are respectively used to connect two main rod bodies 21. One end of at least two support rods 26 is connected to the crossbeam 11, and the other end is respectively connected to the two main rod bodies 21.

[0052] Specifically, at least three support rods 26 are arranged on a cross beam 11. In the embodiment where two main rod bodies 21 are connected together, the two ends of one support rod 26 are connected to the two main rod bodies 21, and the other two support rods 26 are respectively used to connect the two main rod bodies 21 and the cross beam 11 together. This arrangement can increase the support of the cross beam 11 to the main rod bodies 21, and can also strengthen the connection stability between the main rod bodies 21. The support rods 26 can also transmit and decompose the external force on the steel frame structure 20, thereby further improving the rigidity and stability of the steel frame structure 20. In some other embodiments, the steel frame structure includes multiple support rods, and the two ends of at least one support rod are respectively used to connect the pipe piles in two different base groups.

[0053] In one embodiment, on a crossbeam 11, three support rods 26 are sequentially connected end to end to form a triangle shape.

[0054] Specifically, the triangle has stability. In an embodiment where three support rods 26 are provided on a crossbeam 11, the three support rods 26 are connected to each other to form a triangle. Such an arrangement can improve the support for the main rod body 21, and the external force on the main rod body 21 can be transferred to the crossbeam 11 through the support rods 26 for sharing, which can ensure the stability and rigidity of the steel frame structure 20, thereby improving the installation stability of the photovoltaic panel. In some other embodiments, the three support rods are arranged horizontally and spaced apart from each other in the height direction.

[0055] In one embodiment, a connecting piece is provided at the upper end of the pipe pile 10 , and the cross beam 11 is connected to the connecting piece at the upper end of the pipe pile 10 .

[0056] Specifically, the connecting piece at the upper end of the pipe pile 10 is a metal sheet, which is integrally formed with the pipe pile 10, and the cross beam 11 is arranged above the pipe pile 10, and the cross beam 11 is welded to the metal sheet on the pipe pile 10.
