Description

Technical Field

[0001] The present invention relates to the technical field related to photovoltaic power generation equipment, and more precisely to a photovoltaic module installation structure. Background Art

[0002] To mount photovoltaic modules on brackets, existing technology typically uses a combination of clamps and bolts, with the clamps and bolts installed at the four corners of the module. This method requires two to three people to install, and a large number of clamps and bolts are required. This makes installation cumbersome, labor-intensive, and material-intensive.

[0003] To solve the above problems, the field also uses a T-bolt with a retaining nut, or a T-nut with a hexagon socket head bolt for installation and fixation. This installation method does not require a pressure block to fix the component. However, after installation, the T-bolt or T-nut has a small contact area with the C-side of the guide rail frame and a high pressure per unit area. When the component encounters extreme weather on site, the guide rail frame is subjected to a large force, and the C-side will undergo plastic deformation and be easily damaged, causing the component to fall off the bracket, resulting in losses and safety hazards. It can be seen that although the above method can eliminate the need for a pressure block, the contact area between the fixed connector and the guide rail frame is small and is easily damaged in extreme situations.

[0004] In summary, there is a need in the art for a photovoltaic module installation solution that is easy to install and not prone to damage. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, a photovoltaic module mounting structure in the present application is used to mount a photovoltaic module 1. The photovoltaic module 1 is a rectangular plate and includes two brackets 2 and a frame assembly 3. The frame assembly 3 is mounted on the side of the photovoltaic module 1. The frame assembly 3 includes two long frames 31 mounted on the longer sides of the photovoltaic module 1 and two short frames 32 mounted on the shorter sides of the photovoltaic module 1. The long frames 31 are respectively connected to the two brackets 2. Specifically, the bracket 2 has a guide groove 21 coaxial with the bracket 2, and the bottom of the guide groove 21 has a ridge 22 extending along the direction of the guide groove 21. The long frame 31 is arranged inside the guide groove 21, and the bottom of the long frame 31 is engaged with the ridge 22. The bracket 2 has a short side groove 23 at a position corresponding to the short frame 32. The short side groove 23 extends perpendicular to the guide groove 21. The protrusion 22 is interrupted by the short side groove 23. The two ends of the short frame 32 are respectively located in the two short side grooves 23. The short side grooves 23 limit the short frame 32 to prevent the frame assembly 3 from sliding. The short side grooves 23 also leave installation space for the angle brackets used to connect the photovoltaic module 1. The photovoltaic module mounting structure adopts a crimping connection method, which uses fewer parts, is simple and quick to install, requires less labor, and has higher installation efficiency. The connection structure of the photovoltaic module mounting structure is stable and not easily damaged in extreme conditions, and has a longer service life.

[0023] like Figure 4As shown, the bracket 2 is provided with multiple short side grooves 23, which divide the protrusion 22 into multiple segments. The bottom of the long side frame 31 engages with each of the multiple protrusions 22. The segmented protrusion structure has a smaller contact surface during installation, resulting in less resistance during installation. Furthermore, due to the length of the bracket 2, it has a certain degree of twisting and bending after processing, making the segmented protrusion structure more convenient for installation.

[0024] See also Figure 5 、 Figure 7 and Figure 8 The top of the long frame 31 has a component mounting portion 311, which is clamped onto the longer side of the photovoltaic module 1. The bottom of the long frame 31 has two side strips 312 and 314, and the bottoms of the two side strips have protrusions 313 and 315, respectively. The two protrusions are arranged opposite each other and protrude in opposite directions. The top of the protrusion 22 has a boss 221. When the two side strips 312 and 314 are inserted into the guide groove 21, the two side strips 312 and 314 are located on both sides of the protrusion 22, and the two protrusions 313 and 315 are located at the bottom of the boss 211. Both bosses are engaged with the boss 211, realizing the engagement between the long frame 31 and the bracket 1.

[0025] It is worth noting that there is a gap between the two side strips 312 , 314 and the side wall of the guide groove 21 to ensure that the two side strips 312 , 314 have enough space to undergo elastic deformation during the crimping installation process.

[0026] See also Figure 2 and Figure 6 For larger photovoltaic modules 1, the photovoltaic module mounting structure further includes several bracket fastening bolts 24. The bracket fastening bolts 24 penetrate the bracket 2 and extend into the guide groove 21. The bracket fastening bolts 24 also penetrate one of the two side bars. The bracket fastening bolts 25 further improve the reliability, stability, and safety of the connection between the long frame 31 and the bracket 1.

[0027] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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 limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
