Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a recyclable photovoltaic component frame. Background Art

[0002] In today's society, sustainable development has become a global focus. As people's awareness of environmental protection continues to increase, the rational use of resources and the reduction of waste generation have become increasingly important.

[0003] With the booming photovoltaic industry, installed photovoltaic capacity has increased annually. Within the photovoltaic industry's circular economy, photovoltaic panel recycling is a crucial step in ensuring sustainable resource utilization. Module recycling is the final link in the photovoltaic industry chain and is considered the "last mile" of the entire green photovoltaic industry chain.

[0004] Currently, existing photovoltaic module frames typically consist of a long and short frame structure, which are connected at the vertices by connecting angle brackets. These existing connecting angle brackets have a cavity inside, with a smooth outer surface and serrated inner surfaces. The long and short frames are frictionally engaged with the serrated surface. Then, based on positioning requirements, positioning plugs are driven into the cavity of the connecting angle brackets, deforming the smooth surface of the connecting angle brackets to create an interference fit with the other surfaces of the long and short frames, thus completing the connection and assembly of the photovoltaic module frame.

[0005] For example, CN202321467473.3 discloses a photovoltaic module frame, including a frame body and a connecting angle code, a receiving groove for accommodating the connecting angle code is opened on the end face of the frame body, and the connecting angle code is inserted into the receiving groove of the frame body; the connecting angle code includes two connected connectors, the inner side surface of the connector is provided with a latch tooth, the outer side surface of the connector protrudes outward to form a deformation part, the connector has a cavity, a connecting rod is installed in the cavity, one end of the connecting rod is connected to the deformation part, and the connecting rod is located between the deformation part and the latch tooth, and a clamping part deflected toward the direction of the receiving groove is arranged on the side of the deformation part close to the notch of the receiving groove; through the design of the deformation part, the connecting rod and the clamping part, the precision required for the receiving groove of the connecting angle code and the frame body is reduced, the processing difficulty is reduced, and the connection can be firm and a self-locking structure can be achieved.

[0006] With the large-scale utilization of photovoltaic power generation, the recycling of retired and obsolete photovoltaic modules has become an increasingly prominent issue, while also creating significant new business opportunities for the industry. During assembly, the long and short frames and connecting brackets are positioned and fixed through friction and interference fit. During the assembly process, the cavities of the connecting brackets deform when the locating plugs are inserted, making disassembly difficult. This also makes it difficult to sort and recycle the module frame components at the end of a photovoltaic system's lifespan.

[0007] Therefore, it is necessary to further improve the design of the photovoltaic module frame to address this difficulty so that it is easy to disassemble and recycle. Utility Model Content

[0008] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the existing technology, the present invention provides a recyclable photovoltaic module frame which is flexible and efficient to assemble, quick and simple to disassemble, can effectively save time and labor costs, and improve resource recycling efficiency.

[0009] The technical solution adopted by the utility model to solve its technical problems is: a recyclable photovoltaic module frame, including a long frame, a short frame and a connecting angle code; the connecting angle code is installed at the connection position of the long frame and the short frame; the connecting angle code is an L-shaped structure, wherein one side of the L-shaped structure is a short side connecting section, and the other side is a long side connecting section; the inner surface of the short side connecting section has a plurality of serrations, and the outer surface is a smooth surface, and the short frame is respectively matched with the inner and outer surfaces of the short side connecting section; the inner and outer surfaces of the long side connecting section are both smooth surfaces, and a reserved bolt opening is provided on the inner surface of the long side connecting section, the outer surfaces of the long frame and the long side connecting section are matched with each other, and a frame bolt hole is provided at the position of the long frame corresponding to the reserved bolt opening, and the long frame and the long side connecting section are fixed by threaded mounting bolts that are threadedly connected to the reserved bolt opening and the frame bolt hole.

[0010] In the above scheme, compared with the traditional component frame connection structure, the serrations on the long side connection section of the connection angle code are eliminated, and a reserved bolt opening is opened on the long side connection section, while the long frame has corresponding reserved frame bolt holes of the same specifications, which are fixed by mounting bolt threads during the connection assembly of the long frame. For photovoltaic modules, the long frame is longer than the short frame, which makes it more difficult to disassemble and assemble during the disassembly operation. During maintenance, replacement, and disassembly operations, the long frame can be disassembled by spiral fitting, which can effectively improve the efficiency of disassembly and assembly of the long frame and save time and labor costs. At the same time, since both sides of the long frame connection section are smooth and there is no interference from serrations, in actual practice, it is possible to freely choose whether to install a frame on the long side connection section, thereby enhancing the adaptability of the overall recyclable photovoltaic module frame.

[0011] Furthermore, the short side connecting section is formed with a plurality of short side cavities, which can be driven with positioning plugs when necessary to deform the short side connecting section and achieve interference fit with the short frame.

[0012] Furthermore, the long side connecting section is provided with long side chambers at positions on both sides of the reserved bolt holes, wherein positioning plugs can be driven into the long side chambers when necessary to deform the long side connecting section and achieve interference fit with the long frame.

[0013] Furthermore, in order to facilitate the corresponding matching of the long frame and the short frame and improve the processing efficiency and assembly adaptability, the butt ends of the long frame and the short frame are set to be 45° beveled.

[0014] Furthermore, the surfaces of the long frame and the short frame have mounting grooves for the corresponding ends of the connecting angle codes to fit into, and the frame bolt holes are correspondingly opened on the groove surface of the long frame mounting groove close to the photovoltaic component side.

[0015] Furthermore, the installation groove is located at the beveled end of the long frame and the short frame and is located away from the outer end of the photovoltaic module, that is, the installation position of the connecting corner code is located at the outer four corners of the photovoltaic module frame.

[0016] Furthermore, in order to facilitate the long side connecting section and the short side connecting section to be pushed into and connected with their corresponding installation grooves, the long side connecting section and the short side connecting section of the connecting angle code are an integrated L-shaped structure, and the two ends of the L-shaped structure respectively have guiding inclined surfaces that cooperate with the two side groove surfaces of the installation groove.

[0017] Preferably, the connecting angle bracket is made of aluminum profile.

[0018] The beneficial effect of the present invention is that the present invention provides a recyclable photovoltaic module frame with a reasonable structural design. In the connection of long and difficult-to-handle long frames, the long side connecting sections of the connecting angle brackets are no longer serrated and bolted, which effectively simplifies the installation and disassembly process of the long frame, making the assembly of the photovoltaic panel more flexible and efficient. When maintenance or replacement of individual photovoltaic panels is required, the frame can be quickly disassembled for operation, saving time and labor costs. When the photovoltaic system reaches the end of its service life, the easily disassembled long frame is easier to classify and recycle, improving the resource recycling rate and meeting the requirements of sustainable development.

[0019] At the same time, the long side connection section adopts a smooth design, which allows you to flexibly choose whether to install a frame or replace frames of different specifications according to different installation scenarios and needs, thereby enhancing the adaptability of the system. If the photovoltaic system needs to be upgraded or modified in the future, the overall easy-to-remove frame can be adjusted and adapted more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0026] like Figure 1 The recyclable photovoltaic module frame shown is the optimal embodiment of the present utility model.

[0027] The recyclable photovoltaic module frame includes a long frame 2, a short frame 1 and connecting corner brackets.

[0028] The butt ends of the long frame 2 and the short frame 1 are arranged in a 45° bevel, which enables the long frame 2 and the short frame 1 to correspond with each other, thereby improving processing efficiency and assembly adaptability.

[0029] The connecting bracket is installed at the connection position between the long frame 2 and the short frame 1. The connecting bracket is made of aluminum profile and has an L-shaped structure. One side of the L-shaped structure is the short side connecting section 5, and the other side is the long side connecting section 4.

[0030] like Figure 1 As shown, the surfaces of the long and short frames 2 and 1 have mounting grooves for the corresponding ends of the connecting angle brackets to fit into. The mounting grooves are located at the chamfered ends of the long and short frames 2 and 1 and away from the outer ends of the photovoltaic module. In other words, the connecting angle brackets are installed at the four outer corners of the photovoltaic module frame. To facilitate the push-in connection of the long and short connecting segments 4 and 5 into their corresponding mounting grooves, the ends of the L-shaped structure of the connecting angle brackets have guiding slopes 10 that mate with the groove surfaces on both sides of the mounting groove.

[0031] In the connection installation of the long frame 2 and the short frame 1 and the connecting angle code, such as Figure 2 As shown, the inner surface of the short side connecting section 5 has a plurality of serrations 6 , and the outer surface is smooth. The short frame 1 is respectively connected to the inner and outer surfaces of the short side connecting section 5 .

[0032] like Figure 3As shown, the inner and outer surfaces of the long side connecting section 4 are both smooth, and a reserved bolt opening 8 is provided on the inner surface of the long side connecting section 4. The outer surfaces of the long frame 2 and the long side connecting section 4 are smooth and matched, and a frame bolt hole 11 is provided on the long frame 2 at the position corresponding to the reserved bolt opening 8. The long frame 2 and the long side connecting section 4 are threadedly fixed by mounting bolts 3 that are threadedly connected to the reserved bolt opening 8 and the frame bolt hole 11.

[0033] Compared to traditional component frame connection structures, this embodiment eliminates the serrations 6 on the long side connection segments 4 of the angle brackets. Instead, reserved bolt openings 8 are provided on the long side connection segments 4 of the angle brackets, while corresponding frame bolt holes 11 of the same size are reserved on the long frame 2. Mounting bolts 3 are used to thread the long frame 2 during assembly.

[0034] From the perspective of actual assembly, for photovoltaic modules, the long frame 2 is longer than the short frame 1, so there is a greater difficulty in disassembly during the disassembly operation. Compared with the traditional long frame 2 and short frame 1 that need to be disassembled separately with interference fit, this embodiment uses threaded fit to achieve disassembly of the long frame 2 at the assembly position of the long frame 2 that is difficult to install and disassemble. Disassembly and assembly only requires unscrewing or tightening the threads, effectively improving the disassembly and assembly efficiency of the long frame 2 and saving time and labor costs. At the same time, since both sides of the connecting section of the long frame 2 are smooth and there is no interference from the sawtooth 6, in actual practice, it is free to choose whether to install the frame on the long side connecting section 4, thereby enhancing the adaptability of the overall recyclable photovoltaic module frame.

[0035] In actual design, in order to further improve the scope of application of this embodiment, three short side chambers 7 are formed in the short side connecting section 5. Long side chambers 9 are respectively provided at positions on both sides of the long side connecting section 4 corresponding to the reserved bolt holes 8. When necessary, positioning plugs can be driven into the short side chambers 7 to deform the short side connecting section 5 and make an interference fit with the short frame 1. When necessary, positioning plugs can also be driven into the long side chambers 9 to deform the long side connecting section 4 and make an interference fit with the long frame 2. That is, on the basis of adopting threaded connection, the long side connecting section 4 also has a basic structure that can be interference fit with the corresponding long frame 2, which facilitates the use of interference fit to complete the assembly connection of the long side connecting section 4 and the long frame 2 when necessary.

[0036] The recyclable photovoltaic panel frame thus designed has a rational structure. When connecting the long, difficult-to-handle long frame 2, the serrations 6 of the long side connecting segments 4 connecting the corner brackets are eliminated, and bolts are used instead. This effectively simplifies the installation and removal of the long frame 2, making the assembly of the photovoltaic panel more flexible and efficient. When individual photovoltaic panels need to be maintained or replaced, the frame can be quickly disassembled for operation, saving time and labor costs.

[0037] From the perspective of recycling and reuse, when the photovoltaic system reaches the end of its service life, the long frame 2 that is easy to disassemble is easier to classify and recycle, which improves the resource recycling rate and meets the requirements of sustainable development.

[0038] From the perspective of adaptability and subsequent upgrades and modifications, the long side connecting section 4 adopts a smooth design, and can flexibly choose whether to install a frame or replace frames of different specifications according to different installation scenarios and needs, thereby enhancing the adaptability of the system. If the photovoltaic system needs to be upgraded or modified in the future, the overall easy-to-remove frame can be adjusted and adapted more conveniently.

[0039] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
