Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module installation, and in particular to a photovoltaic module installation structure, and further to a photovoltaic module. Background Art

[0002] Photovoltaic modules (also called solar panels) are the core and most important part of a solar power generation system.

[0003] Photovoltaic modules use solar energy to generate electricity. They have the advantages of advanced technology but low cost, long-term reliability, safety and cleanliness, and no geographical restrictions. With the continuous growth of global demand for clean energy, the application and promotion of photovoltaic power generation systems are becoming more and more extensive. As a sustainable energy option, photovoltaic power generation is of great significance to environmental protection and energy transformation.

[0004] The photovoltaic modules are installed on the bracket of the photovoltaic power generation system, specifically on the crossbeam of the bracket. The crossbeam is the keel of the photovoltaic power generation system. For the photovoltaic modules arranged at the edge of the bracket, they need to be fixed with the help of edge pressure blocks. The edge pressure blocks fix the photovoltaic modules on the crossbeam. For example, an existing patent with announcement number CN206268187U, entitled "Mounting Clips for Photovoltaic Modules and Photovoltaic Modules", uses edge pressure blocks in conjunction with mounting clips to fix the photovoltaic modules arranged at the edge of the bracket on the crossbeam. In actual applications, the thickness specifications of photovoltaic modules (i.e. photovoltaic panels) are inconsistent, and the single edge pressure block of the prior art model is difficult to match the installation and use of photovoltaic modules of various thickness specifications, and has the defect of poor applicability.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present embodiment discloses a photovoltaic module mounting structure, which is applied in the field of mounting photovoltaic modules arranged at the edge of a bracket. The structure can change the specifications and models according to the thickness specifications of different photovoltaic modules, so as to match the installation and use of photovoltaic modules of various thickness specifications, and has good applicability and a wide range of applications.

[0036] Reference Figure 1 and Figure 2 The photovoltaic module installation structure includes an edge pressure block 1 and a cross beam 2. The edge pressure block 1 includes a main vertical plate 11 and a photovoltaic gusset plate 12 and a fixing plate 13 respectively arranged at both ends of the main vertical plate 11. The photovoltaic gusset plate 12 and the main vertical plate 11, as well as the fixing plate 13 and the main vertical plate 11 are all integrated structures, and the photovoltaic gusset plate 12 and the fixing plate 13 extend in opposite directions on the main vertical plate 11. The edge pressure block 1 is similar to a Z shape as a whole. During installation and application, the main vertical plate 11 is attached to the side of the frame 10 of the photovoltaic panel 9, the photovoltaic gusset plate 12 is attached to the top surface of the frame 10 of the photovoltaic panel 9, and the fixing plate 13 is attached to the top surface of the cross beam 2. Specifically, a fixing hole 131 is provided on the fixing plate 13, and a fastener 4 is passed through the fixing hole 131 from top to bottom. The fastener 4 can be a bolt, and a spring washer 7 is sleeved on the bolt. A guide rail groove 21 is provided above the middle of the interior of the beam 2, and the top of the beam 2 has an opening structure 22 connected to the guide rail groove 21, and the opening width of the opening structure 22 is smaller than the groove width of the guide rail groove 21. The fastener 4 passes through the opening structure 22 and extends into the guide rail groove 21. A sliding buckle 3 is adapted to be provided in the guide rail groove 21, and the sliding buckle 3 is movable in the guide rail groove 21. A fastening hole 31 is provided on the sliding buckle 3, and the fastener 4 is threadedly connected with the fastening hole 31 on the sliding buckle 3. Therefore, once the fastener 4 is tightened, the side pressure block 1 and the beam 2 can be fixed. At this time, the photovoltaic buckle plate 12 is pressed against the top surface of the frame 10 of the photovoltaic panel 9, so the photovoltaic panel 9 is fixed on the beam 2.

The inner buckle 8 can be attached to the opening edge of the frame 10 of the photovoltaic panel 9, so that the photovoltaic module can be limited in the direction of the cross beam 2, and the chamfer structure 81 makes a gap between the inner buckle 8 and the photovoltaic panel 9 to avoid the inner buckle 8 pressing on the photovoltaic panel 9 and causing damage to the photovoltaic panel 9. On the other hand, the side of the photovoltaic buckle plate 12 facing the main vertical plate 11 is provided with a serrated surface 121, and the serrated surface 121 is distributed along the length direction of the photovoltaic buckle plate 12, that is, distributed along the direction perpendicular to the cross beam 2. The serrated surface 121 is adapted to engage with the serrated groove 101 on the top surface of the frame 10 of the photovoltaic panel 9, so that the photovoltaic module can be limited in the direction perpendicular to the cross beam 2. As described above, in combination with the inner buckle portion 8 and the serrated surface 121 and the serrated groove 101, the photovoltaic component can be limited. Therefore, even if the fastener 4 becomes loose, the photovoltaic component will not easily fall off the beam 2, thereby improving the installation stability of the photovoltaic component.

Specifically, the vertical plate adjustment component 5 includes a half-wall-thickness convex plate 1 51 and a half-wall-thickness convex plate 2 52.

In order to prevent the upper vertical plate 111 and the lower vertical plate 112 from detaching from each other, a dovetail groove 512 is opened in the middle part of the half-wall-thick convex plate 1 51, and the dovetail groove 512 is arranged along the height direction. A dovetail slider 522 is arranged on the half-wall-thick convex plate 2 52. The dovetail slider 522 and the half-wall-thick convex plate 2 52 are an integrated structure. The dovetail slider 522 is slidably arranged in the dovetail groove 512.
