Description

Technical Field

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

[0002] A photovoltaic (PV) mounting system is a support structure used to install and secure solar photovoltaic (PV) modules (such as solar panels). It plays a crucial role in a solar PV power generation system, ensuring that the PV modules are securely mounted on the ground, roof, or other building structures. It also determines the optimal tilt angle and orientation of the PV modules to maximize sunlight capture and improve power generation efficiency.

[0003] Patent CN220067275U discloses a photovoltaic (PV) support system, comprising a column, a main shaft, purlins, and PV modules. The column is mounted on a base surface. The main shaft is positioned on the column, with its extension forming an angle with the base surface. Purlins are mounted on the main shaft, with multiple purlins spaced apart along its extension direction. The PV modules are mounted on the purlins and include a first-area module and a second-area module. The first-area modules are arranged in two rows along the transverse direction of the main shaft, while the second-area modules are arranged in a single row. This configuration improves the load-bearing capacity of the PV support system, enhancing system stability while ensuring power generation.

[0004] However, the above-mentioned photovoltaic support system still has the following problems in actual use:

[0005] Solar panels are mostly installed in remote locations, which means that when moving the solar panels to the installation site, it is often necessary to use trucks or other tools. Since the columns of solar panels are usually quite long, even longer trucks are needed for transportation. If the number of solar panels being transported is not large, the space above the truck will be wasted. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a folding structure and photovoltaic support bracket, which allows the columns to be folded and stored when only a small number of brackets need to be transported, reducing their length and enabling the use of smaller trucks or other means of transportation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a folding structure comprising eight columns, four long and four short, with the four long columns divided into two groups and the four short columns divided into two other groups. A first folding component is connected between two columns in the same group, and a second folding component is connected to the other end of the first folding component. A third folding component is connected to the other end of the second folding component. Two third folding components between the two groups of long columns are simultaneously connected to E-shaped blocks, and two third folding components between the two groups of short columns are simultaneously connected to another E-shaped block.

[0008] Furthermore, the first folding assembly includes a first U-shaped block and two extension blocks. The inner wall of one side of the first U-shaped block is rotatably connected to one end of the two columns in the same group. The two ends of the other side of the first U-shaped block are respectively fixedly connected to one end of the two extension blocks. Both extension blocks are connected to the second folding assembly.

[0009] Furthermore, the second folding component includes an elliptical block and a second U-shaped block. One end of the elliptical block is rotatably connected to two extension blocks, and the other end of the elliptical block is rotatably connected to the inner wall of one side of the second U-shaped block. The other side of the second U-shaped block is connected to the third folding component.

[0010] Furthermore, the third folding assembly includes two connecting rods and two connecting blocks. The same end of each connecting rod is fixedly connected to the side of the second U-shaped block away from the elliptical block. The other ends of each connecting rod are fixedly connected to one end of each connecting block. The other ends of each connecting block are rotatably connected to the inner wall of the E-shaped block.

[0011] Furthermore, the rotation axes of the column and the first U-shaped block, the two extension blocks and the elliptical block, the elliptical block and the second U-shaped block, and the two connecting blocks and the E-shaped block are all fastened together by bolts and screws.

[0012] A photovoltaic support includes two inclined beams and two crossbeams mounted on the two inclined beams, and also includes the aforementioned folding structure, with four columns at the upper end respectively fastened to the two inclined beams by bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This folding structure and photovoltaic bracket, through a four-long-four-short column grouping design, combined with the multi-stage folding structure of No. 1, No. 2 and No. 3 folding components, can be folded in three stages to reduce the overall length of the column. This effectively solves the problem of traditional photovoltaic brackets taking up a lot of space during transportation due to the excessive length of the columns. It supports the use of smaller trucks or transportation vehicles to complete the transfer, and is especially suitable for the transportation needs of a small number of photovoltaic panels installed on the roof of rural houses.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-5 A folding structure includes eight pillars 1, four long and four short. The four long pillars 1 are divided into two groups, and the four short pillars 1 are divided into two other groups. A first folding component is connected between two pillars 1 in the same group. The other end of the first folding component is connected to a second folding component. The other end of the second folding component is connected to a third folding component. Two third folding components between the two groups of long pillars 1 are simultaneously connected to E-shaped blocks 9. Two third folding components between the two groups of short pillars 1 are simultaneously connected to another E-shaped block 9.

[0023] The folding structure and photovoltaic bracket in this utility model are similar to existing photovoltaic bracket structures, such as the photovoltaic bracket disclosed in patent publication number CN220067275U. Figures 1 to 5 As shown, in this utility model, when transporting the folding structure and photovoltaic bracket, if there are only a few brackets (for example, only a small number of photovoltaic panels are installed on the roof of a rural house), in order to avoid the situation where the transport truck (or other transport vehicle) is not long enough due to the brackets being too long, only eight columns 1 ( Four long columns 1 together, four short columns 1 Together, as Figure 1 and Figure 2Fold as shown;

[0024] Specifically, first fold the four long columns 1 (or four short columns 1) together to the same side using the first folding assembly (e.g., Figure 3 After folding, fold the four long columns 1 (or four short columns 1) to the other side via folding component number three (e.g., Figure 4 Finally, the four long columns 1 (or four short columns 1) are folded again using the second folding assembly (e.g., Figure 5 This allows for adjustments to the overall length of the support structure, facilitating transportation.

[0025] As a preferred embodiment of this utility model, the first folding component includes a first U-shaped block 4 and two extension blocks 10. The inner wall of one side of the first U-shaped block 4 is rotatably connected to one end of the two columns 1 in the same group. The two ends of the other side of the first U-shaped block 4 are respectively fixedly connected to one end of the two extension blocks 10. Both extension blocks 10 are connected to the second folding component.

[0026] More specifically, when the four long pillars 1 (or four short pillars 1) need to be folded for the first time, simply rotate pillar 1. Pillar 1 will rotate inside the first U-shaped block 4, and the two pillars 1 inside the same first U-shaped block 4 will merge and align, thereby reducing the overall length.

[0027] As a preferred embodiment of this utility model, the second folding component includes an elliptical block 5 and a second U-shaped block 6. One end of the elliptical block 5 is rotatably connected to two extension blocks 10, and the other end of the elliptical block 5 is rotatably connected to the inner wall of one side of the second U-shaped block 6. The other side of the second U-shaped block 6 is connected to the third folding component.

[0028] More specifically, when it is necessary to fold the four long pillars 1 (or the four short pillars 1) for the third time, simply rotate the pillars 1. The pillars 1, along with the first U-shaped block 4 and the two extension blocks 10, will rotate together, thereby reducing the overall length again.

[0029] As a preferred embodiment of this utility model, the No. 3 folding assembly includes two connecting rods 7 and two connecting blocks 8. The same end of the two connecting rods 7 is fixedly connected to the side of the No. 2 U-shaped block 6 away from the elliptical block 5. The other end of the two connecting rods 7 is fixedly connected to one end of the two connecting blocks 8 respectively. The other end of the two connecting blocks 8 is rotatably connected to the inner wall of the E-shaped block 9.

[0030] More specifically, when the four long pillars 1 (or four short pillars 1) need to be folded a second time, the pillars 1 are rotated. At this time, the pillars 1, the first U-shaped block 4, the two extension blocks 10, the elliptical block 5, the second U-shaped block 6, the two connecting rods 7 and the two connecting blocks 8 rotate together inside the E-shaped block 9, thereby reducing the overall length.

[0031] As a preferred embodiment of this utility model, the rotation axis of the column 1 and the first U-shaped block 4, the rotation axis of the two extension blocks 10 and the elliptical block 5, the rotation axis of the elliptical block 5 and the second U-shaped block 6, and the rotation axis of the two connecting blocks 8 and the E-shaped block 9 are all fastened together by bolts and screws.

[0032] More specifically, by using bolts and screws to fasten the above components, firstly, the components can be folded when the bolts and screws are loosened; secondly, during actual use, they can be directly fastened using bolts and screws, eliminating the need for purchasing corresponding bolts and screws, which is convenient and quick; finally, the bolts and screws prevent the components from loosening and separating during transportation.

[0033] A photovoltaic support includes two inclined beams 2 and two crossbeams 3 mounted on the two inclined beams 2, and also includes the aforementioned folding structure, wherein four columns 1 located at the upper end are respectively fastened to the two inclined beams 2 by bolts.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
