Description
Technical Field
[0001] This utility model relates to the technical field of connecting photovoltaic brackets and precast pipe piles, and particularly to a connection structure for photovoltaic brackets and precast pipe piles. Background Technology
[0002] In photovoltaic power generation systems, solar panels serve as the core carriers of energy conversion, and their installation efficiency and operational stability are highly dependent on the supporting photovoltaic support structure.
[0003] Single-row, single-slope support structures are one of the most common structural forms for ground-mounted fixed photovoltaic systems, widely used in integrated projects such as grass-solar hybrid, forest-solar hybrid, and fishery-solar hybrid. Among these, prestressed concrete pipe pile single-column supports have become one of the mainstream technical routes due to their high efficiency and economy. In this structural system, inclined beams are supported by columns and diagonal braces, thereby supporting the solar panels. The connection between the columns and diagonal braces and the precast concrete pipe pile foundation is usually achieved through clamps. Although clamp connections have the advantages of simplicity and efficiency, in practical engineering applications, insufficient circumferential tightening force can easily lead to relative slippage of components, causing the clamps to tilt on the precast concrete pipe piles, resulting in misalignment of the supporting components and thus structural instability.
[0004] Therefore, it is necessary to improve the existing connection structure between photovoltaic brackets and precast pipe piles to prevent the clamps from tilting on the precast pipe piles, thereby improving the stability of the photovoltaic brackets. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a connection structure between a photovoltaic support and a precast pipe pile, including a clamp, an inclined beam, two columns and two diagonal braces, a limiting member, and a precast pipe pile with a limiting hole for limiting the rotation of the limiting member in a vertical plane. The clamp surrounds the precast pipe pile, the limiting member is disposed in the limiting hole and both ends protrude from the outer surface of the precast pipe pile, the columns are arranged along the axial direction of the precast pipe pile, the two columns are respectively disposed on both sides of the precast pipe pile, and the columns are detachably fixedly connected to the clamp, the top of the column is detachably fixedly connected to the inclined beam, and the column is also detachably fixedly connected to the portion of the limiting member protruding from the outer surface of the precast pipe pile, the two diagonal braces are respectively located on both sides of the precast pipe pile, one end of the diagonal brace is detachably fixedly connected to the inclined beam, and the other end is detachably fixedly connected to the portion of the limiting member protruding from the outer surface of the precast pipe pile.
[0007] Optionally, the clamp, the limiting member, the inclined beam, the column, and the inclined brace are located in the same vertical plane.
[0008] Optionally, the limiting hole penetrates the precast pipe pile radially.
[0009] Optionally, the limiting member protrudes from both ends of the outer surface of the precast pipe pile and is symmetrically arranged about the axis of the precast pipe pile.
[0010] Optionally, during the production of the limiting component, a marking line is reserved at a distance of D / 2 from both sides of the axis of symmetry, where D is the outer diameter of the precast pipe pile.
[0011] Optionally, the shape of the limiting hole is adapted to the shape of the limiting member, the radial cross-sectional dimension of the limiting hole is larger than the cross-section of the limiting member, and an adhesive layer is filled between the limiting hole and the limiting member.
[0012] Optionally, the radial cross-section of the limiting hole is 2 mm larger than the cross-section of the limiting member.
[0013] Optionally, the limiting member is a flat steel, and the thickness of the limiting member is 5mm~7mm.
[0014] Optionally, the two diagonal braces are located on both sides of the precast pipe pile, with one end of the diagonal brace connected to the inclined beam and the other end connected to the portion of the limiting member protruding from the outer surface of the precast pipe pile.
[0015] Optionally, the clamp is positioned closer to the top of the precast pipe pile than the limiting member.
[0016] The connection structure between a photovoltaic support and a precast pipe pile provided by this utility model has the following beneficial effects:
[0017] Since the two columns are respectively set on both sides of the precast pipe pile, and the columns are detachably and fixedly connected to the clamps, and the top of the columns is detachably and fixedly connected to the inclined beam, the inclined beam and the precast pipe pile can be connected through the columns. Since the precast pipe pile has a limiting hole for restricting the rotation of the limiting member in the vertical plane, and the limiting member is set in the limiting hole with both ends protruding from the outer surface of the precast pipe pile, the limiting hole of the precast pipe pile can restrict the limiting member from tilting in the vertical plane. Since the columns are detachably and fixedly connected to the clamps and the portion of the limiting member protruding from the outer surface of the precast pipe pile, and the two diagonal braces are detachably and fixedly connected to the portion of the limiting member protruding from the outer surface of the precast pipe pile, the limiting member has the function of restricting the tilt of the columns and the two diagonal braces relative to the precast pipe pile in the vertical plane, that is, it can restrict the tilt of the inclined beam, improve the stability of the photovoltaic support, and thus improve the wind resistance.

Figure 4This is a partially enlarged schematic diagram from another perspective of the connection structure between the photovoltaic support and the precast pipe pile in this embodiment of the present invention. This embodiment provides a connection structure between the photovoltaic support and the precast pipe pile, including a limiting member 100, a clamp 200, an inclined beam 300, two columns 400, and a precast pipe pile 500 with limiting holes for restricting the rotation of the limiting member 100 in the vertical plane. The clamp 200 surrounds the precast pipe pile 500. The limiting member 100 is disposed within the limiting holes and both ends protrude from the outer surface of the precast pipe pile 500. The columns 400 are arranged along the axial direction of the precast pipe pile 500. Two columns 400 are respectively disposed on both sides of the precast pipe pile 500, and the columns 400 are detachably and fixedly connected to the clamp 200. The top of the columns 400 is detachably and fixedly connected to the inclined beam 300. The columns 400 are also detachably and fixedly connected to the portion of the limiting member 100 protruding from the outer surface of the precast pipe pile 500. Two diagonal braces 600 are respectively located on both sides of the precast pipe pile 500.

Therefore, the limiting hole of the precast pipe pile 500 can restrict the limiting member 100 from tilting or shifting in the vertical plane. Since the column 400 and the diagonal brace 600 are also detachably fixedly connected to the portion of the limiting member 100 protruding from the outer surface of the precast pipe pile 500, the limiting member 100 has the function of restricting the column 400 and the diagonal brace 600 from tilting relative to the precast pipe pile 500 in the vertical plane. That is, it can restrict the tilt of the inclined beam 300, which can improve the stability of the photovoltaic support and thus improve the wind resistance.

[0036] Preferably, the radial cross-sectional dimension of the limiting hole is larger than the cross-sectional dimension of the limiting member 100, and an adhesive layer is filled between the limiting hole and the limiting member 100. This facilitates the installation of the limiting member 100 and improves installation efficiency.

[0038] The thickness of the flat steel is 5mm to 7mm, preferably 6mm.
[0039] Marking lines are reserved on the surface of the flat steel component at a distance of D / 2 from both sides of the axis of symmetry during production. These lines are used for positioning when piercing the precast pipe pile 500. Here, D is the outer diameter of the precast pipe pile 500.

[0041] Preferably, the diagonal brace 600 can be a C-shaped steel.
[0042] Furthermore, the clamp 200 is positioned closer to the top of the precast pipe pile 500 than the limiting member 100, thus forming a reliable connection between the column 400 and the precast pipe pile 500.

[0045] The connection structure between the photovoltaic support and the precast pipe pile also includes a structural nut 710 and a structural bolt 720. The limiting member 100 protrudes from the outer surface of the precast pipe pile 500 and is provided with a connection hole. The column 400 is also provided with a through hole. The structural bolt 720 passes through the connection hole and the through hole and is threadedly connected to the structural nut 710. This facilitates the installation of the connection structure between the photovoltaic support and the precast pipe pile and improves the installation efficiency of the connection structure between the photovoltaic support and the precast pipe pile.
