Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic bracket. Background Art
[0002] In photovoltaic power station projects, pipe piles and upper columns together form the supporting structure of photovoltaic modules to meet the needs of overall stability of photovoltaic brackets during and after assembly while adapting to the terrain. In the prior art, a suitable gap needs to be retained between the upper column and the pipe pile selected for general pipe pile photovoltaic brackets, and there is a certain range of selection standards. Usually, after the pipe pile specifications are fixed, the corresponding upper column specifications are selected, or the corresponding pipe pile specifications are made according to the selected upper column specifications, and then fixedly connected to the pipe pile by bolting or welding, so as to achieve the function of bracket stability.
[0003] In some project sites, the pipe piles may be larger in size, while the corresponding upper columns may be smaller in size to meet the load-bearing requirements of the photovoltaic bracket. In this case, larger columns are usually used to match the larger pipe piles, resulting in material waste and increased costs. If smaller columns are used, it is easy to cause problems with the positioning of the columns and pipe piles during installation, resulting in the columns and pipe piles being non-concentric, which in turn causes the center of gravity of the photovoltaic bracket to shift, affecting the safety and service life of the photovoltaic bracket.
[0004] Therefore, it is necessary to provide a new photovoltaic bracket to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a photovoltaic support with a constraint plate, so as to solve the problem of misalignment caused by shaking or swaying of a small-sized upper column and a larger-sized pipe pile during and after assembly.

[0010] As a further improved technical solution of the utility model, the outer diameter of the constraint plate is equal to the outer diameter of the pipe pile.
[0011] As a further improved technical solution of the utility model, the outer diameter of the constraint plate is greater than the outer diameter of the pipe pile.
[0012] As a further improved technical solution of the utility model, the diameter of the through hole is not less than the outer diameter of the upper column.
[0013] As a further improved technical solution of the utility model, the through hole is circular, rectangular, waist-shaped or elliptical, and there is a clearance fit between the through hole and the upper column.
[0014] As a further improved technical solution of the utility model, the connecting member includes at least one group of abutment bolts, which pass through the pipe pile from the outside and abut the outer wall of the upper column. Each group of the abutment bolts is arranged at the same horizontal height and is evenly distributed, and the extension line of each group of the abutment bolts intersects on the central axis of the pipe pile.

[0026] See also Figures 1 to 4As shown, this embodiment discloses a photovoltaic support, including a pipe pile 1 and an upper column 2, wherein the upper column 2 is at least partially located inside the pipe pile 1 and at least partially located above the pipe pile 1, and the upper end of the upper column 2 is used to support the photovoltaic module. A constraint plate 3 is provided at the end of the pipe pile 1, and the upper column 2 is fixed to the pipe pile 1 through a connector after passing through the constraint plate 3. The photovoltaic support reduces the installation gap between the upper column 2 and the pipe pile 1, and well solves the problems of the upper column 2 being skewed and the upper column 2 being non-concentric with the pipe pile 1.
[0027] It should be noted that the pipe pile 1 and the upper column 2 in the present invention are both slender objects, and their lengths are omitted in some drawings.
[0028] The pipe pile 1 adopts a steel structure, and the size, length and layout of the pipe pile 1 are determined according to the geological conditions of the installation site. The influence of natural factors such as wind load, snow load, earthquake, etc. needs to be considered during design to ensure that the pipe pile 1 can remain stable under various extreme weather conditions.
[0029] See also Figure 1 and Figure 3 As shown, the constraint plate 3 is provided with a through hole 31, and the through hole 31 is arranged at the center of the constraint plate 3. The through hole 31 is adapted to the outer peripheral contour of the upper column 2, and the hole axis of the through hole 31, the central axis of the pipe pile 1, and the central axis of the upper column 2 coincide with each other. The upper column 2 is penetrated by the through hole 31, and the through hole 31 limits the upper column 2. There is a clearance fit between the through hole 31 and the upper column 2. The setting of the constraint plate 3 reduces the clearance between the upper column 2 and the pipe pile 1.
[0030] In this embodiment, the upper column 2 is a round tube, and the through hole 31 is correspondingly set as a round hole. In other embodiments, the upper column 2 can be a square tube or an H-shaped tube, and the through hole 31 is correspondingly set as a rectangular hole. In other embodiments, the through hole 31 can also be a waist-shaped hole or an elliptical hole, as long as it can ensure that the upper column 2 can pass normally and provide a limit for the upper column 2.
[0031] Furthermore, the restraining plate 3 is made of metal and is welded to the top of the pipe pile 1. In this embodiment, the restraining plate 3 is specifically a steel plate.
[0032] In this embodiment, the outer contour of the constraint plate 3 is the same as the outer contour of the pipe pile 1, both of which are circular, which is more convenient for welding and more beautiful; the present application does not limit the outer contour of the constraint plate 3, which can be circular, square or other shapes. Furthermore, the outer diameter of the constraint plate 3 is larger than the outer diameter of the pipe pile 1 to facilitate welding.
[0033] In other embodiments, the outer diameter of the constraint plate 3 is equal to the outer diameter of the pipe pile 1. It should be noted that the outer diameter of the constraint plate 3 must be set to be equal to the outer diameter of the pipe pile 1 at a minimum to prevent the constraint plate 3 from falling into the pipe pile 1 during welding, or the constraint plate 3 from tilting to affect the installation of the upper column 2 and the limiting effect on the upper column 2.
[0034] The aperture of the through hole 31 of the constraint plate 3 is not less than the outer diameter of the upper column 2. In this embodiment, the aperture of the through hole 31 is larger than the outer diameter of the upper column 2. Specifically, the aperture of the through hole 31 is slightly larger than the outer diameter of the upper column 2. There is a gap between the outer edge of the through hole 31 and the outer wall of the upper column 2, and the gap is equal everywhere. In this way, the through hole 31 reduces the installation gap between the upper column 2 and the pipe pile 1, limits the upper column 2, and solves the problems of the upper column 2 being skewed and the upper column 2 being not concentric with the pipe pile 1, and is not easy to cause damage to the upper column 2. In other embodiments, the aperture of the through hole 31 can also be equal to the outer diameter of the upper column 2 to completely limit the upper column 2.
[0035] The restraining plate 3 of this embodiment is easy to manufacture and can be designed according to the shape and size of the pipe pile 1 and the upper column 2 in actual application. It has strong interchangeability and can adapt to different installation requirements. The restraining plate 3 and the pipe pile 1 are connected in a rigid connection manner, and do not need to be assembled separately on the construction site.
[0036] See also Figures 1 to 4 As shown, the connecting member includes at least one group of abutment bolts 4, which pass through the pipe pile 1 from the outside and abut the outer wall of the upper column 2 to fix the upper column 2 to the pipe pile 1. Further, each group of abutment bolts 4 is arranged at the same horizontal height and is evenly distributed, and the extension line of each group of abutment bolts 4 intersects with the central axis of the pipe pile 1, that is, intersects with the central axis of the upper column 2, so that the force applied by the abutment bolts 4 to the pipe pile 1 and the upper column 2 can be evenly distributed, so as to achieve a better fixing effect and high stability.
[0037] See also Figures 1 to 4 As shown, the connecting member further includes at least one through bolt 5, one end of which passes through the pipe pile 1 and the upper column 2 from one side and passes out from the other side of the pipe pile 1 to strengthen the connection and fixation between the upper column 2 and the pipe pile 1. Further, the through bolt 5 is at least partially located on the central axis of the pipe pile 1, that is, on the central axis of the upper column 2, and the through bolt 5 passes through the pipe pile 1 and the upper column 2 horizontally to better play the effect of strengthening the connection and fixation.
[0038] For further information, see Figure 1 , Figure 2 and Figure 4As shown, the connector also includes a gasket 6, which is disposed between the through bolt 5 and the pipe pile 1 to improve the connection firmness between the through bolt 5 and the upper column 2 and the pipe pile 1. Further, the two sides of the gasket 6 abut against the outer wall of the through bolt 5 and the pipe pile 1, respectively, and the gasket 6 is disposed on both sides of the pipe pile 1.
[0039] In some embodiments, two groups of abutment bolts 4 are provided, and at least one through bolt 5 is located between the two groups of abutment bolts 4 so that the connection stress between the abutment bolts 4 and the through bolts 5 on the upper column 2 and the pipe pile 1 is symmetrically distributed.
[0040] In this embodiment, the photovoltaic bracket is provided with two groups of abutment bolts 4, which are parallelly distributed up and down, and each group includes three abutment bolts 4, which are evenly distributed at intervals, that is, they are evenly distributed at an angle difference of 120° on the outer periphery of the pipe pile 1 and pass through the pipe pile 1 and abut against the outer wall of the upper column 2; a through bolt 5 is provided, which is located between the upper and lower groups of abutment bolts 4, and one end of the through bolt 5 passes through the pipe pile 1 and the upper column 2, and the other end is left on one side of the pipe pile 1. The abutment bolt 4 and the through bolt 5 cooperate to connect and fix the upper column 2 and the pipe pile 1.
[0041] In summary, compared with the prior art, the photovoltaic support of the utility model has the following advantages: by fixing the constraint plate 3 on the top of the pipe pile 1, the problem of shaking or swaying of the small-sized upper column 2 and the larger-sized pipe pile 1 during and after assembly when there is a large gap between the upper column 2 and the pipe pile 1 is solved, so as to achieve the effect of satisfying product stability even if the gap is large; the constraint plate 3 is simple to produce and has strong interchangeability, can adapt to different installation requirements, and can also disperse the concentrated stress of the pipe pile 1, thereby extending the service life of the pipe pile 1. While ensuring structural strength and stability, the photovoltaic support can shorten the production cycle, reduce material consumption, reduce material, transportation, installation, labor and other costs, and improve production efficiency.
