Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to an installation reinforcement block for an open frame of a solar photovoltaic component. Background Art

[0002] At present, the connection between the aluminum frame of solar photovoltaic modules and the photovoltaic support system is installed by bolts, nuts, flat washers, and spring washers. This installation method requires two-handed operation, and the operation process is cumbersome and inefficient. There is also a risk of missing parts (flat washers / spring washers). In addition, the bolts and nuts may not be effectively locked or fall off during the installation process, further affecting the installation quality and efficiency.

[0003] Photovoltaic modules are used outdoors and need to withstand loads such as wind and snow. According to the IEC61215 standard, the load test of photovoltaic modules needs to meet the requirements of 2400pa wind load on the back and 5400pa wind load and snow load on the front. If the connection between the photovoltaic module frame and the photovoltaic support system is not supported enough and the installation is not firm, the photovoltaic module will fall off during outdoor use, causing serious economic losses and safety hazards. The current traditional installation method is to install M8 nuts and flat washers on the inner side of the C side of the frame (see Fig.11 ), this method is prone to leaking flat gaskets, which poses a long-term safety hazard, and requires two-handed operation, which makes the construction and installation efficiency low. In order to overcome the above problems, it is necessary to seek a more stable, reliable and quick-to-install connection method. Summary of the invention

[0004] The purpose of the utility model is to provide a mounting reinforcement block for an open frame of a photovoltaic module to solve the problems raised in the above-mentioned background technology.

[0005] For the above purpose, the utility model provides the following technical solutions: a mounting reinforcement block for an open-type frame of a photovoltaic module, comprising a reinforcement block body, including a mounting portion, a connecting portion, a supporting portion and a disassembly portion, wherein a threaded hole is opened on the mounting portion, the connecting portion and the disassembly portion are respectively connected to two ends of the mounting portion, and the supporting portion is fixed to the upper end of the connecting portion, and its supporting surface is parallel to the mounting portion.

[0006] Preferably, the connecting portion is a U-shaped connecting portion, comprising a first reinforcement segment, a second reinforcement segment and a third reinforcement segment connected in sequence, and the second reinforcement segment is perpendicular to the mounting portion.

[0007] Preferably, the support portion is L-shaped, the transverse portion thereof is a support surface parallel to the mounting portion, and the longitudinal portion thereof forms an angle of 30-50° with the transverse portion.

[0008] Preferably, the disassembly portion comprises a disassembly portion body, and an upper protrusion, a groove and a lower protrusion are provided at one end of the disassembly portion body away from the mounting portion.

[0009] Preferably, the connection between the connecting portion and the mounting portion and the supporting portion, the connection between the second reinforcement segment and the first reinforcement segment and the third reinforcement segment, and the connection between the transverse portion and the longitudinal portion of the supporting portion are all provided with rounded corners.

[0010] Preferably, an oblique angle structure is provided at the bottom of the first reinforcement section of the connecting portion and the bottom of the lower protrusion.

[0011] Technical effects and advantages of the utility model:

[0012] 1. This structure has the functions of both component bolt hole installation and local reinforcement of component frame, which can greatly increase the force-bearing area of ​​the C surface of the frame, and the installation locking area is larger, more firm and reliable. The long-term outdoor load performance of photovoltaic components is better, and it can be quickly installed and matched with the photovoltaic component frame. When installing the photovoltaic component, it can be rotated and inserted into the frame cavity, and can be operated with a single-handed electric tool. The installation process prevents parts from being missed (flat gaskets), which greatly saves construction manpower and time.

[0013] 2. Quick disassembly buckle design. If disassembly is required, force is applied upward along the upper protrusion, and the elastic deformation of the aluminum material is utilized. Combined with the bevel design at the bottom, the bolt installation reinforcement can be removed from the frame section.

[0014] 3. The design of the support part increases the support strength of the installation reinforcement block. The support surface parallel to the installation part ensures that the photovoltaic module is evenly supported. The L-shaped support part design, with its transverse part as the support surface, is parallel to the installation part, providing a stable support effect; the longitudinal part and the transverse part are at an angle of 30-50°, which helps to adjust the angle and positioning during installation.

[0015] 4. The design of the U-shaped connection part is perpendicular to the reinforcement section of the installation part, which enhances the connection stability between the installation part and the support part and improves the torsion and bending resistance of the entire installation reinforcement block.

[0016] 5. Rounded corners are provided at the connection between the connecting part and the mounting part, the connection between the supporting part and the connection between the supporting part itself, which helps to reduce stress concentration and improve the strength and durability of the structure.

[0017] 6. Easy to install and disassemble, the design of the bevel structure, at the bottom of the first reinforcement section of the connecting part and the bottom of the lower protrusion, helps to guide the positioning during the installation process, reduces the difficulty of installation, and also saves the use of aluminum materials.
