AI Technical Summary
In traditional photovoltaic brackets, the flat steel clamps and precast pipe piles are prone to loosening, resulting in uneven stress between the end steel plate and the end face of the precast pipe pile, which is especially prone to instability when strong winds blow.
Multiple strips of flat iron are distributed around the side wall of the pile using clamp units, and fixed to the clamps by the top plate. This increases the force and frictional resistance between the clamps and the pile, ensuring a tight fit and stabilizing the load on the support column.
The tighter connection between the clamp and the pile body is enhanced, improving stress stability, preventing loosening and swaying, and ensuring that the support column remains stable under wind force.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support. Background Technology
[0002] Traditional photovoltaic (PV) systems typically use precast reinforced concrete pipe piles as the supporting foundation. For example, Chinese utility model patent CN217881937U specifically discloses a grounding device for a solar-fishery hybrid PV power station. This is based on the disclosed content and appendices... Figure 2-5 It is known that the pipe pile support is fixed to the outer wall of the precast pipe pile using grounding flat steel clamps and fixing flat steel clamps. However, this installation method has some problems: because the flat steel clamps (including grounding flat steel clamps and fixing flat steel clamps) are formed in two separate halves, when fixing the pipe pile support to the outer wall of the precast pipe pile, the pipe diameter of the pipe pile support is large and larger than the thickness of the flat steel clamps. This results in a large gap between the two halves, and the flat steel clamps and the precast pipe pile are prone to loosening. The force and frictional resistance do not meet the requirements (the welding of the end steel plate to the flat steel clamp results in a gap between the flat steel clamp and the precast pipe pile, which limits the force and frictional resistance between the flat steel clamp and the precast pipe pile). Especially when strong winds blow, the force between the end steel plate and the end face of the precast pipe pile becomes unstable (unstable). Utility Model Content
[0003] In order to overcome the defects of the existing technology, this utility model provides a photovoltaic bracket to solve the problem that the flat steel clamp is easy to loosen with the precast pipe pile, resulting in unstable force between the end steel plate and the end face of the precast pipe pile.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a photovoltaic bracket, including a plurality of support columns, a plurality of piles, and an mounting frame for installing photovoltaic panels. The top end of the support column is fixedly connected to the mounting frame, and the bottom end of the support column is fixedly connected to the pile through a clamp unit. The clamp unit includes a top plate fixed to the bottom end face of the support column, a plurality of strip-shaped flat irons, and at least two clamps. The top plate is placed on the top end face of the pile. The plurality of strip-shaped flat irons are distributed around the side wall of the pile, and the top ends of the plurality of strip-shaped flat irons are fixedly connected to the edge of the top plate. At least two clamps fix the plurality of strip-shaped flat irons to the side wall of the pile. In the radial direction of the pile, the strip-shaped flat irons are located between the pile and the clamps.
[0005] As a further embodiment, at least two of the clamps are spaced apart, with the bottom clamp fixed to the bottom end of the plurality of strip-shaped flat irons.
[0006] As a further solution, multiple stiffening ribs are fixed between the bottom end of the support column and the top plate.
[0007] As a further embodiment, the cross-section of the pile is polygonal, and the multiple strip-shaped flat irons correspond to multiple sides of the pile.
[0008] As a further embodiment, the polygon is octagonal, and the number of strip-shaped flat irons is eight.
[0009] As a further embodiment, the diameter of the pile gradually decreases from the end closer to the support column to the end farther away from the support column, and the bottom end of the pile has a conical tip.
[0010] As a further option, the pile body is made of concrete and contains multiple steel bars.
[0011] As a further embodiment, the mounting frame includes a crossbeam and multiple purlins. The crossbeam is fixedly connected to the multiple purlins via purlin brackets, and the crossbeam and purlins are arranged intersecting each other. The top of the support column is fixedly connected to the crossbeam.
[0012] The beneficial effects of this utility model are as follows: This utility model fixes the top plate to the bottom end face of the support column, and fixes the top ends of multiple strip-shaped flat irons to the edge of the top plate. Then, it fixes the multiple strip-shaped flat irons to the side wall of the pile body through at least two clamps. In this way, the multiple strip-shaped flat irons tighten the clamps and the pile body, increasing the force and frictional resistance between the clamps and the pile body, making it less prone to loosening. Furthermore, it makes the top plate fit tightly against the top end face of the pile body, so that it is subjected to stable force and does not shake, thereby stabilizing the support column.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] As attached Figure 1 As shown, this embodiment provides a photovoltaic support frame, including several support columns 1, several piles 5, and a mounting frame 2 for installing photovoltaic panels 4. The mounting frame 2 is used to install photovoltaic panels 4. Specifically, the mounting frame 2 includes a crossbeam 21 and multiple purlins 22. The crossbeam 21 is fixedly connected to the multiple purlins 22 through purlin brackets 23, and the crossbeam 21 and the purlins 22 are arranged intersectingly. The multiple purlins 22 are connected into a single mounting frame 2 by the crossbeam 21, and then the photovoltaic panels 4 are installed on the multiple purlins 22.
[0021] The top of support column 1 is fixedly connected to mounting bracket 2, as detailed in the attached document. Figure 1 As shown, the top of the support column 1 is fixedly connected to the crossbeam 21, thus serving to support the mounting frame 2. The support column 1 and the crossbeam 21 can be made of steel.
[0022] As attached Figure 1-2 As shown, the bottom end of the support column 1 is fixedly connected to the pile body 5 via a clamp unit 3. The clamp unit 3 includes a top plate 31 welded and fixed to the bottom end face of the support column 1 (as an improvement, see attached). Figure 4 As shown, multiple stiffening ribs 32 (which act as reinforcing ribs) can be fixed between the bottom end of the support column 1 and the top plate 31 by welding. Multiple strip flat irons 33 and at least two clamps 34 are also fixed. The top plate 31 is placed on the top end face of the pile body 5. The multiple strip flat irons 33 are distributed around the side wall of the pile body 5, and the top ends of the multiple strip flat irons 33 are fixedly connected to the edge of the top plate 31 by welding. At least two clamps 34 fix the multiple strip flat irons 33 to the side wall of the pile body 5. In the radial direction of the pile body 5, the strip flat irons 33 are located between the pile body 5 and the clamps 34.
[0023] This invention fixes a top plate 31 to the bottom end face of the support column 1, and fixes the top ends of multiple strip-shaped flat irons 33 to the edge of the top plate 31. Then, it fixes the multiple strip-shaped flat irons 33 to the side wall of the pile body 5 through at least two clamps 34. In this way, the multiple strip-shaped flat irons 33 tighten the clamps 34 and the pile body 5, increasing the force and frictional resistance between the clamps 34 and the pile body 5, making it less prone to loosening. Furthermore, it makes the top plate 31 fit tightly against the top end face of the pile body 5, so that it is subjected to stable force and does not shake, thereby stabilizing the support column 1.
[0024] Furthermore, at least two clamps 34 are spaced apart, with the bottom clamp 34 fixed to the bottom end of multiple strip-shaped flat irons 33. (See attached image) Figure 2 As shown, when two clamps 34 are used, one clamp 34 is fixed to the middle of the strip flat iron 33 and the other clamp 34 is fixed to the bottom of the strip flat iron 33, so that the whole is subjected to uniform force and the overall stress stability is increased.
[0025] In one embodiment, the pile body 5 has a polygonal cross-section, with multiple strip-shaped flat irons 33 corresponding to multiple sides of the pile body 5. This allows the strip-shaped flat irons 33 to fit more closely to the sides of the pile body 5, further increasing the force and frictional resistance between the clamp 34 and the pile body 5. (See attached...) Figure 5 As shown, in some embodiments, the polygon is octagonal, and the number of strip flat irons 33 is eight.
[0026] As an improvement, see attached Figure 1 As shown, the diameter of the pile body 5 gradually decreases from the end closer to the support column 1 to the end farther away from the support column 1. When the clamp 34 fixes multiple strip flat irons 33 to the side wall of the pile body 5, it will form a downward pulling force on the multiple strip flat irons 33 and the top plate 31, so that the top plate 31 fits more tightly against the top end face of the pile body 5, making it stable under force, and thus able to stabilize the support column 1.
[0027] In addition, the bottom end of the pile 5 is tapered, which facilitates its insertion into the ground. Furthermore, the pile 5 is made of concrete and contains multiple reinforcing bars, thereby enhancing its load-bearing capacity and durability.
[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
