Description

Technical Field

[0001] This utility model relates to the photovoltaic field, specifically a photovoltaic support structure. Background Technology

[0002] Photovoltaic equipment is a device that uses solar radiation to generate electricity. Since photovoltaic supports in centralized photovoltaic equipment are usually based on piles, existing photovoltaic supports typically use piles as a foundation to ensure the strength and lifespan of the photovoltaic supports. However, when installing photovoltaic equipment in mountainous areas, the uneven terrain requires workers to adjust the piles according to the height and then fix them by welding to ensure the strength of the photovoltaic supports. Due to the complex construction conditions in mountainous areas, fixing by welding seriously affects the installation efficiency of photovoltaic equipment. Utility Model Content

[0003] In view of this, this utility model provides a photovoltaic support bracket to solve the problem that when existing photovoltaic support brackets use piles as foundations, the installation efficiency of photovoltaic equipment is affected by workers fixing the photovoltaic support brackets by welding.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A photovoltaic support structure includes: a column, a pre-embedded pipe, and a casting component;

[0006] The lower end of the pre-embedded pipe is embedded in the casting component, and the upper end of the pre-embedded pipe is provided with a first fixing structure.

[0007] Along the axial direction of the column, the column is provided with multiple second fixing structures, which cooperate with the first fixing structure to connect the column and the pre-embedded pipe.

[0008] Preferably, the cast-in-place component is reinforced with main bars and stirrups;

[0009] The stirrups are fitted onto the main reinforcement bars.

[0010] Preferably, the stirrups are spiral structures.

[0011] Preferably, the spacing of the stirrups gradually increases from top to bottom.

[0012] Preferably, the upper end of the main reinforcing bar is welded to the lower end of the pre-embedded pipe.

[0013] Preferably, it also includes: through bolts and nuts;

[0014] The upper end of the pre-embedded pipe is radially provided with a first through hole for the through bolt to pass through, forming a first fixing structure;

[0015] The column has a second through hole in its radial direction for the through bolt to pass through, forming a second fixing structure;

[0016] The nut and the through bolt are threaded together.

[0017] Preferably, the inner diameter of the pre-embedded pipe is larger than the outer diameter of the column.

[0018] Preferably, it also includes: fixing bolts;

[0019] Multiple screw holes that mate with fixing bolts are provided along the circumference of the pre-embedded pipe.

[0020] Preferably, the outer wall of the embedded pipe is provided with an anti-corrosion layer.

[0021] Preferably, the outer wall of the embedded pipe is coated with anti-corrosion paint.

[0022] Based on the photovoltaic bracket provided by this utility model, the lower end of the pre-embedded pipe is embedded in the casting component, and a first fixing structure is provided at the upper end of the pre-embedded pipe. Along the axial direction of the column, the column is provided with multiple second fixing structures, which cooperate with the first fixing structure for connecting the column and the pre-embedded pipe. The photovoltaic bracket disclosed above, because it has multiple second fixing structures along the axial direction of the column that cooperate with the first fixing structure, allows for quick connection between the column and the pre-embedded pipe when installing photovoltaic equipment in uneven mountainous areas. This is achieved by first adjusting the column height according to the height of the photovoltaic equipment, and then using the cooperation of the first and second fixing structures. This improves the installation efficiency of the photovoltaic equipment. Compared with existing welding methods, this not only reduces the installation difficulty of the photovoltaic bracket but also effectively improves its installation efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model embodiment provides a photovoltaic bracket, see [link]. Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a photovoltaic support system, which includes: a column 1, a pre-embedded pipe 2, and a casting component 3;

[0030] The lower end of the pre-embedded pipe 2 is embedded in the casting component 3, and the upper end of the pre-embedded pipe 2 is provided with a first fixing structure.

[0031] Along the axial direction of column 1, column 1 is provided with multiple second fixing structures, wherein the second fixing structures cooperate with the first fixing structure for connecting column 1 and pre-embedded pipe 2.

[0032] It should be noted that the casting component 3 of this application is a component formed by concrete and steel reinforcement, which not only has good rigidity but is also corrosion resistant.

[0033] In this embodiment of the invention, the lower end of the pre-embedded pipe 2 is pre-embedded in the casting component 3, and a first fixing structure is provided at the upper end of the pre-embedded pipe 2. Along the axial direction of the column 1, the column 1 is provided with multiple second fixing structures, which cooperate with the first fixing structure to connect the column 1 and the pre-embedded pipe 2. The above describes a photovoltaic support system. Because multiple second fixing structures that cooperate with the first fixing structure are provided along the axial direction of the column 1, when installing photovoltaic equipment in uneven mountainous areas, the height of the column 1 is adjusted according to the height of the photovoltaic equipment. Then, through the cooperation of the first and second fixing structures, the connection between the column 1 and the pre-embedded pipe 2 can be quickly achieved, thereby improving the installation efficiency of the photovoltaic equipment. Compared with existing welding methods, this not only reduces the installation difficulty of the photovoltaic support system but also effectively improves the installation efficiency.

[0034] Specifically, the casting component 3 is equipped with main reinforcement bars 31 and stirrups 32;

[0035] Stirrup 32 is fitted onto main reinforcement 31.

[0036] It should be noted that by pre-embedding the main reinforcement 31 and stirrups 32 in the cast-in-place component 3, and by having the stirrups 32 fitted onto the main reinforcement 31, not only can the load-bearing capacity of the cast-in-place component 3 be improved, but the stability of the cast-in-place component 3 can also be guaranteed, effectively ensuring the service life of the photovoltaic support.

[0037] Furthermore, stirrup 32 has a spiral structure.

[0038] It should be noted that the stirrup 32 can be a spiral structure or a circular structure, and those skilled in the art can choose according to their needs.

[0039] It is worth noting that when the stirrup 32 is a circular structure, multiple stirrups 32 can be sequentially set along the length of the main reinforcement 31 to ensure the load-bearing capacity and stability of the cast-in-place component 3.

[0040] Specifically, the spacing of the stirrups 32 gradually increases from top to bottom.

[0041] It should be noted that setting the spacing of the stirrups 32 to gradually increase from top to bottom can save materials while ensuring the load-bearing capacity and stability of the cast part 3.

[0042] Specifically, the upper end of the main rib 31 is welded to the lower end of the pre-embedded pipe 2.

[0043] It should be noted that welding the upper end of the main rib 31 to the lower end of the pre-embedded pipe 2 ensures the connection strength between the main rib 31 and the pre-embedded pipe 2, and ensures the load-bearing capacity and stability of the photovoltaic support.

[0044] It should also be noted that the upper end of the main rib 31 of this application is welded to the lower end of the pre-embedded pipe 2. The main rib 31 can be welded to the pre-embedded pipe 2 before implantation, which can avoid the problem of difficult welding at high places and effectively ensure the installation efficiency of photovoltaic equipment.

[0045] Furthermore, the photovoltaic support also includes: through bolts 4 and nuts 5;

[0046] The upper end of the pre-embedded pipe 2 is radially provided with a first through hole for the through bolt 4 to pass through, forming a first fixing structure;

[0047] The column 1 has a second through hole in the radial direction for the through bolt 4 to pass through, forming a second fixing structure;

[0048] Nut 5 is threadedly fitted with through bolt 4.

[0049] It should be noted that this application connects the column 1 and the pre-embedded pipe 2 by using the through bolt 4 and nut 5, which not only makes installation convenient but also allows for adjustment according to the height of the photovoltaic equipment, effectively improving the installation efficiency of the photovoltaic equipment.

[0050] Preferably, column 1 is a cylindrical structure.

[0051] It should be noted that the column 1 can be a cylindrical structure or other types of structures (such as polygonal prisms), and those skilled in the art can choose according to their needs.

[0052] Preferably, the pre-embedded pipe 2 has a cylindrical structure.

[0053] It should be noted that the pre-embedded pipe 2 can be a cylindrical structure or other types of structures (such as polygonal prisms), and those skilled in the art can choose according to their needs.

[0054] Specifically, the inner diameter of the pre-embedded pipe 2 is larger than the outer diameter of the column 1.

[0055] It should be noted that the inner diameter of the pre-embedded pipe 2 is set to be larger than the outer diameter of the column 1. When the column 1 and the pre-embedded pipe 2 need to be fixedly connected, the lower end of the column 1 can be inserted into the pre-embedded pipe 2. Then, the height of the column 1 is adjusted according to the height required by the photovoltaic equipment. After the height of the column 1 is adjusted (the first through hole and the second through hole must be aligned), the through bolt 4 is inserted into one side of the first through hole in sequence, then inserted into the second through hole, and protrudes from the other side of the first through hole. Finally, the pre-embedded pipe 2 and the column 1 are fixed by the threaded engagement of the nut 5 and the through bolt 4.

[0056] It should also be noted that the inner diameter of the embedded pipe 2 can be set to be larger than the outer diameter of the column 1, or the inner diameter of the column 1 can be set to be larger than the outer diameter of the embedded pipe 2. When the inner diameter of the column 1 is set to be larger than the outer diameter of the embedded pipe 2, the lower end of the column 1 is fitted onto the embedded pipe 2 (i.e., the upper end of the embedded pipe 2 is inserted into the lower end of the column 1). Then, the height of the column 1 is adjusted according to the height required by the photovoltaic equipment. After the height of the column 1 is adjusted (the first through hole and the second through hole must be aligned), the through bolt 4 is inserted into one side of the second through hole in sequence, then inserted into the first through hole, and protrudes from the other side of the second through hole. Finally, the embedded pipe 2 and the column 1 are fixed by the threaded engagement of the nut 5 and the through bolt 4.

[0057] It is worth noting that the first through hole opened in the pre-embedded pipe 2 refers to two corresponding holes opened on the pipe wall of the pre-embedded pipe 2, and the two holes are symmetrical.

[0058] The second through hole opened in column 1 refers to two corresponding holes opened on the pipe wall of column 1. The two holes are symmetrical. Therefore, the symmetrical bolt can pass through the first through hole and the second through hole at the same time and cooperate with the nut 5 to realize the cooperation between column 1 and the pre-embedded pipe 2.

[0059] In this embodiment of the application, the lower end of the column 1 can also be set on one side of the pre-embedded pipe 2, and the column 1 and the pre-embedded pipe 2 can also be connected by passing the through bolt 4 through the first through hole and the second through hole in sequence and cooperating with the nut 5.

[0060] Preferably, the outer diameter of the column 1 is 3mm to 5mm smaller than the inner diameter of the pre-embedded pipe 2.

[0061] It should be noted that making the outer diameter of the column 1 3mm to 5mm smaller than the inner diameter of the pre-embedded pipe 2 not only makes it easier to insert the lower end of the column 1 into the pre-embedded pipe 2, but also avoids excessive shaking between the column 1 and the pre-embedded pipe 2 due to excessive gap.

[0062] Specifically, the photovoltaic support system also includes: 6 fixing bolts;

[0063] Multiple screw holes 21 that mate with fixing bolts 6 are provided along the circumference of the pre-embedded pipe 2.

[0064] It should be noted that multiple screw holes 21 are provided along the circumference of the pre-embedded pipe 2 to cooperate with the fixing bolts 6. After the pre-embedded pipe 2 is fixed to the column 1 by the through screw, the screws of multiple fixing bolts 6 simultaneously press against the column 1 through the cooperation of the fixing bolts 6 and the screw holes 21, so as to prevent the column 1 from shaking due to the gap between it and the pre-embedded pipe 2, and further improve the stability of the photovoltaic bracket.

[0065] Preferably, a nut that mates with the fixing bolt 6 is welded to the screw hole 21 position of the pre-embedded pipe 2.

[0066] It should be noted that, due to the limited wall thickness of the pre-embedded pipe 2, the external force applied when the fixing bolt 6 is engaged with the screw hole 21 is too large, which can easily cause stripping. Therefore, by welding a nut that engages with the fixing bolt 6 at the screw hole 21 position of the pre-embedded pipe 2, the problem of stripping between the fixing bolt 6 and the screw hole can be avoided, and the connection strength and stability between the column 1 and the pre-embedded pipe 2 can be further guaranteed.

[0067] Preferably, there are 3 fixing bolts 6 and 3 screw holes 21.

[0068] Specifically, the outer wall of the pre-embedded pipe 2 is provided with an anti-corrosion layer.

[0069] It should be noted that by providing an anti-corrosion layer on the outer wall of the pre-embedded pipe 2, the exposed part of the pre-embedded pipe 2 can be prevented from being corroded, thus further ensuring the service life of the photovoltaic bracket.

[0070] Specifically, the outer wall of the pre-embedded pipe 2 is coated with anti-corrosion paint.

[0071] It should be noted that the outer wall of the pre-embedded pipe 2 can be protected from corrosion by spraying anti-corrosion paint, by electroplating an anti-corrosion layer, or by wrapping other anti-corrosion materials. Those skilled in the art can choose according to their needs. However, in this utility model, spraying anti-corrosion paint is preferred as the anti-corrosion layer of the pre-embedded pipe 2.

[0072] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
