Description

Technical Field

[0001] The utility model belongs to the technical field of solar energy, and in particular relates to an assembled solar photovoltaic component short side support frame. Background Art

[0002] At present, solar photovoltaic modules generally include brackets and frames, on which photovoltaic panels are installed. The frames are connected to each other through angle brackets. The angle brackets are located inside the frame and are connected and fixed as a whole through built-in angle brackets at the four corners. The built-in angle brackets need to be fully pushed into the cavity of the frame. This operation process is usually complicated and requires precise alignment and appropriate force. This not only increases the difficulty of installation, but also makes the entire installation process time-consuming and laborious. Since the angle brackets are located inside the frame, the operating space is limited during installation, which makes it difficult to use installation tools, further increasing the difficulty of installation. The built-in angle brackets mainly play a connecting role, but their own bearing capacity is relatively weak. When photovoltaic modules are subjected to external forces such as wind and snow pressure for a long time, the angle bracket connection is prone to loosening or deformation, thereby affecting the structural stability and safety of the entire module. When photovoltaic modules are used outdoors, they need to withstand various complex external forces, including wind loads, snow loads, temperature changes, etc. These external forces will generate certain loads and pull-out forces on the modules. However, the current design of angle brackets often cannot meet these requirements, resulting in problems with the modules during long-term use. Summary of the invention

[0003] The purpose of the utility model is to provide an assembled solar photovoltaic assembly long side support frame to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled solar photovoltaic module short side support frame, comprising a photovoltaic open frame, the photovoltaic installation groove and the open corner code cavity, the open corner code cavity comprises an end plate, a back plate and a bottom plate surrounded by three sides, a lower bend is provided on the outer edge of the end plate, an upper bend is provided on the outer edge of the bottom plate, and a group of rivets are symmetrically provided on the inner walls of the lower bend and the upper bend;

[0005] The angle code includes an angle code body, which includes two long frame insertion parts and short frame insertion parts that are perpendicular to each other and are L-shaped. A plurality of parallel guide teeth are provided on the inner surfaces of the long frame insertion parts and the short frame insertion parts. The guide teeth are inclined in the direction of the connection between the long frame insertion parts and the short frame insertion parts. A plurality of weight-reducing through grooves are opened on the sides of the long frame insertion parts and the short frame insertion parts, and a supporting rib is provided between two adjacent weight-reducing through grooves. The position of the rivet block corresponds to the supporting rib.

[0006] Preferably, a plurality of reinforcing ribs are provided on the inner side of the back plate.

[0007] Preferably, guide structures are provided at the ends of both the long frame insertion portion and the short frame insertion portion.

[0008] Preferably, a space-avoiding groove is provided at the connection between the long frame insertion part and the short frame insertion part of the corner code, and the space-avoiding groove is opened on the short frame insertion part.

[0009] Preferably, an anti-mistake groove is provided on the outer side of the supporting rib of the short frame insertion portion.

[0010] Technical effects and advantages of the utility model:

[0011] 1. By setting the open angle code cavity and the guide teeth of the angle code, it can be ensured that the angle code can be easily and accurately inserted into the corresponding position of the photovoltaic open frame.

[0012] 2. The corresponding setting of rivet blocks and supporting ribs not only enhances the connection strength between the corner brackets and the photovoltaic open frame, but also ensures the structural stability of the entire short side support frame.

[0013] 3. The design of the weight-reducing through-slot can reduce the weight of the angle bracket while ensuring the structural strength, thereby increasing the lightweight degree of the entire frame. The setting of the reinforcing ribs increases the strength of the back panel and prevents the back panel from being deformed or damaged when subjected to external forces.

[0014] 4. The opening of the fool-proof groove, through the difference in shape or size, makes the angle code only be inserted in the correct direction, effectively preventing the occurrence of misoperation.

[0015] 5. The opening of the avoidance groove not only reduces the weight of the angle code, but also ensures that the angle code can smoothly avoid possible obstacles when inserted, thereby improving the smoothness of installation. BRIEF DESCRIPTION OF THE DRAWINGS
