Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panels, and in particular to a spliced ​​photovoltaic panel structure. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that uses semiconductor materials (such as silicon) to convert sunlight into direct current (DC). The panel mainly consists of a laminate, an aluminum alloy frame, and a junction box. The laminate includes tempered glass, EVA film, silicon-based solar cells, and a backsheet, achieving both light transmission protection and photoelectric conversion. Common PV panels are typically fixedly mounted on brackets for outdoor installation. In practice, PV panels require manual splicing and installation, and electrical connections between panels must be made before and after splicing, resulting in low installation efficiency. Therefore, we designed a splicing PV panel structure. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a splicing photovoltaic panel structure, which can effectively solve the problem that existing photovoltaic panels are usually fixedly installed on brackets for outdoor use. In the actual installation process, photovoltaic panels need to be manually spliced ​​and laid, and the wires between photovoltaic panels need to be electrically connected before and after splicing, resulting in low installation efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A modular photovoltaic panel structure includes a photovoltaic panel body, with a terminal block elastically connected to one outer wall of the photovoltaic panel body, and an overlap groove opened on the other side of the photovoltaic panel body. The terminal block and the overlap groove are inserted into each other. Overlap strips are symmetrically installed on the rear wall of the photovoltaic panel body. The structure also includes a through groove through the rear wall of the photovoltaic panel body, in which a mounting bracket is inserted. A fixing buckle is engaged on the mounting bracket to fix the positions of the two overlapping strips that are in contact.

[0006] Preferably, the photovoltaic panel body has an installation groove on the outer wall near the terminal block, the terminal block is elastically connected to the installation groove by a spring, and the outer wall of the terminal block and the installation groove are in sliding fit.

[0007] Preferably, the terminal block is electrically connected to the photovoltaic panel body, and a metal ring electrically connected to the photovoltaic panel body is laid on the inner wall of the overlapping groove. When the terminal block is inserted into the overlapping groove, the terminal block and the metal ring in the overlapping groove are overlapped, and at this time, two adjacent photovoltaic panels are electrically connected.

[0008] Preferably, a sealing plug is fitted on the outer wall of the terminal block, and the sealing plug is interference-fitted with the lap groove.

[0009] Preferably, the outer wall of the mounting bracket is provided with a plurality of mounting holes evenly distributed, and the outer wall of the fixing buckle is fixedly installed with a positioning post, and the positioning post is inserted into the mounting hole.

[0010] Preferably, the outer wall of the fixing buckle is provided with a first inclined surface, and the outer wall of the overlapping strip is provided with a second inclined surface. When the positioning post on the fixing buckle is inserted into the mounting hole, the first inclined surface and the second inclined surface are in close contact.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention enables a stable electrical connection between two adjacent photovoltaic panels through the plug-in connection between the terminal block and the splicing groove. Furthermore, the sliding connection between the through groove and the mounting frame allows for the rapid splicing of photovoltaic panels.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] Example: Refer to Appendix Figure 1 - Appendix Figure 5As shown, a splicing photovoltaic panel structure includes a photovoltaic panel body 100. A terminal post 110 is elastically connected to one outer wall of the photovoltaic panel body 100. An overlap groove 103 is provided on the other side of the photovoltaic panel body 100. The terminal post 110 and the overlap groove 103 are inserted into each other. The structure also includes a through groove 101 that is opened through the rear wall of the photovoltaic panel body 100. A mounting frame 200 is inserted into the through groove 101. Specifically, in this application, during the actual splicing process, the photovoltaic panel body 100 is slidably installed along the mounting frame 200 and pushed to a predetermined position by the through groove 101 opened on the rear wall of the photovoltaic panel body 100 and the sliding fit between the mounting frame 200 and the through groove 101. During the actual installation process, the photovoltaic panel body 100 is pushed to a predetermined position by sliding along the mounting frame 200. After the photovoltaic panel body 100 is pushed to a fixed position on the mounting frame 200, the photovoltaic panel body 100 is installed again in the above manner to achieve rapid installation between photovoltaic panel bodies 100.

[0028] Specifically, to ensure the fixation of the position of the first photovoltaic panel body 100 installed on the mounting frame 200, as one embodiment, a protrusion can be provided on the mounting frame 200. This protrusion can fix the position of the photovoltaic panel body 100. The mounting frame 200 mentioned in this application is fixed to the ground by a bracket. As mentioned above, when the second photovoltaic panel body 100 is installed, it is also slidably installed along the mounting frame 200. Regarding the stable electrical connection between two adjacent photovoltaic panel bodies 100, in this application, the photovoltaic panel body 100... A terminal 110 is elastically connected to the outer wall of one side of the photovoltaic panel 100. When two photovoltaic panel bodies 100 come into contact, the corresponding terminal 110 is inserted into the overlapping groove 103 opened on the outer wall of the adjacent photovoltaic panel body 100, and the terminal 110 and the photovoltaic panel body 100 are electrically connected. A metal ring that is electrically connected to the photovoltaic panel body 100 is laid on the inner wall of the overlapping groove 103. When the terminal 110 is inserted into the overlapping groove 103, the terminal 110 and the metal ring in the overlapping groove 103 are overlapped. At this time, the two adjacent photovoltaic panel bodies 100 are electrically connected.

[0029] Furthermore, a mounting groove 102 is formed on the outer wall of the photovoltaic panel body 100 near the terminal post 110. The terminal post 110 is elastically connected to the mounting groove 102 by a spring 111, and the outer wall of the terminal post 110 slides in fit with the mounting groove 102. When two adjacent photovoltaic panel bodies 100 are in stable contact, the end of the corresponding terminal post 110 is located inside the overlapping groove 103. In conjunction with the elastic connection between the terminal post 110 and the mounting groove 102 through the spring 111, stable contact between the terminal post 110 and the metal ring laid on the inner wall of the overlapping groove 103 can be ensured, thereby achieving a stable electrical connection between two adjacent photovoltaic panel bodies 100.

[0030] Specifically, to ensure the safety of the circuit connection points of the photovoltaic panel body 100 and avoid the risk of leakage during rainy weather, in this application, a sealing plug 120 is fitted on the outer wall of the terminal 110, and the sealing plug 120 is interference-fitted with the overlapping groove 103. During actual installation, when the terminal 110 is inserted into the overlapping groove 103, the sealing plug 120 fitted on the outer wall of the terminal 110 will also be inside the overlapping groove 103 and close to the outside. At this time, the sealing plug 120 will be at the connection position of two adjacent photovoltaic panel bodies 100, effectively sealing the electrical connection position of the photovoltaic panel body 100 and effectively reducing the risk of leakage caused by moisture in the external environment.

[0031] Furthermore, to improve the relative fixation of the photovoltaic panel bodies 100 after splicing, in this application, overlapping strips 130 are symmetrically fixedly installed on the rear wall of the photovoltaic panel bodies 100, and fixing buckles 300 are snapped onto the mounting frame 200. The fixing buckles 300 are used to fix the positions of the two overlapping strips 130 that are in contact. Multiple mounting holes 201 are evenly provided on the outer wall of the mounting frame 200, and positioning posts 310 are fixedly installed on the outer wall of the fixing buckles 300. The positioning posts 310 are inserted into the mounting holes 201. After the installation of two adjacent photovoltaic panel bodies 100 is completed, the fixing buckles 300 can snap and fix the overlapping strips 130 on the rear wall, i.e., the bottom outer wall, of the two adjacent photovoltaic panel bodies 100. The fixing buckles 300 have a U-shaped structure, which improves the snapping effect of the overlapping strips 130 and ensures the fixation of the relative positions of the two adjacent photovoltaic panel bodies 100 after splicing.

[0032] Furthermore, a first inclined surface 301 is provided on the outer wall of the fixing buckle 300, and a second inclined surface 131 is provided on the outer wall of the overlapping strip 130. When the positioning post 310 on the fixing buckle 300 is inserted into the mounting hole 201, the first inclined surface 301 and the second inclined surface 131 are in close contact. After the two adjacent photovoltaic panel bodies 100 are installed, the fixing buckle 300 is snapped onto the outside of the two overlapping strips 130 that are in contact. With the insertion and engagement relationship between the positioning post 310 and the mounting hole 201, the fixing buckle 300 and the mounting frame 200 can be fixedly connected. During the snapping process, the first inclined surface 301 will contact and press against the second inclined surface 131, achieving stable contact between the two photovoltaic panel bodies 100 and ensuring a stable electrical connection between the two adjacent photovoltaic panel bodies 100.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
