Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component auxiliary parts, in particular to an adjustable photovoltaic component connecting part. Background Art

[0002] Currently, the scale of my country's photovoltaic industry continues to expand, and the industry is generally developing well. With the further development of my country's photovoltaic industry, it is expected that the market capacity of the photovoltaic industry will show an annual growth trend in the next few years.

[0003] Photovoltaic modules are usually fixedly installed in a support frame, which makes it easy to place the photovoltaic modules and absorb sunlight. However, when photovoltaic modules with poor performance need to be replaced, since the support frame is usually an integrated metal bracket with high hardness, it is easy for the support frame to scratch or rub the photovoltaic modules during installation and replacement, thereby causing damage to the equipment.

[0004] As disclosed in Chinese patent CN219576953U, a photovoltaic module support frame is proposed. The first side panel, the second side panel and a plurality of connecting parts are connected by the connecting parts, so that the connecting parts support the photovoltaic module, the first side panel and the second side panel clamp the photovoltaic module, and limit and fix the photovoltaic module. The length of the connecting parts can be adjusted, and then the spacing between the first side panel and the second side panel is adjusted, so that the support frame is suitable for photovoltaic modules of different sizes. When the photovoltaic module is replaced, the first side panel and the second side panel can be separated from the photovoltaic module to avoid friction or scratches on the photovoltaic module, thereby avoiding damage to the photovoltaic equipment. This solves the problem of existing integrated metal brackets that are prone to friction or scratches on the photovoltaic module when installing and replacing the photovoltaic module, thereby causing damage to the photovoltaic equipment.

[0005] However, the connection method between photovoltaic modules and the main cable used in existing technologies directly determines the reliability of photovoltaic power generation projects. If this connection point is not safe and reliable, an accident can cause significant economic losses. Traditional connection methods require customized connectors based on module specifications, resulting in long lead times and hindering project construction plans. Secondly, traditional connection methods also make the connectors unreliable and prone to slippage when connected to the main cable, which cannot fully guarantee the safety of the modules during their service life.

[0006] For this reason, we urgently need to provide an adjustable photovoltaic component connector. Utility Model Content

The traditional connection method requires the corresponding connector to be customized according to the specifications of the module, which has a long supply cycle and is not conducive to the construction plan of the project. Secondly, the traditional connection method is that the connection between the connector and the main lock is unreliable and prone to slipping, which cannot fully guarantee the safety of the module during its use cycle.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Example 1:

[0029] An adjustable photovoltaic component connector includes a photovoltaic panel 1, the outer surface of the photovoltaic panel 1 is connected to a flexible connection structure, the bottom of the flexible connection structure is provided with a pressing limit structure, and the bottom of the pressing limit structure is provided with a connection fixing structure.

[0030] The flexible connection structure includes a limiting unit and a disassembly unit. The disassembly unit is mounted on top of the limiting unit. The limiting unit includes a base plate 101, with an outer tooth plate 102 mounted near the middle of the top surface of the base plate 101. An upper plate 103 is provided on top of the base plate 101, and an inner tooth plate 104 is mounted near the middle of the bottom surface of the upper plate 103. The disassembly unit includes a nut 105, with a washer 106 mounted on the bottom of the nut 105, and the bottom surface of the washer 106 abuts the top of the upper plate 103.

[0031] The bottom end of the outer tooth plate 102 is fixedly connected to the top surface of the bottom plate 101 near the middle, and the top end of the inner tooth plate 104 is fixedly connected to the bottom surface of the upper plate 103 near the middle. The two inner tooth plates 104 are arranged between the two outer tooth plates 102.

[0032] By setting up a flexible connection structure, when the nut 105 is threadedly connected to the top of the U-bolt 301, the bottom plate 101 and the upper plate 103 squeeze and fix the photovoltaic panel 1 to complete the flexible connection of the photovoltaic panel. At the same time, the outer tooth plate 102 and the inner tooth plate 104 are used to protect the side of the photovoltaic panel 1 to prevent deformation caused by collision.

[0033] When the nut 105 is threadedly connected to the top of the U-bolt 301, the gasket 106 is abutted against the upper plate 103, thereby driving the upper plate 103 to be pressed downward, so that the upper plate 103 and the bottom plate 101 are abutted and clamped to fix the photovoltaic panel 1. At the same time, the installation of the outer tooth plate 102 and the inner tooth plate 104 can buffer the side of the photovoltaic panel 1 to prevent the edge of the photovoltaic panel 1 from colliding during the installation process, thereby causing deformation and other damage.

[0034] Example 2:

[0035] Based on the first embodiment, the press-limiting structure includes a pressing block 201. Limiting blocks 202 are fixedly mounted on the left and right ends of the front and back sides of the bottom surface of the pressing block 201. Sliding holes are opened in the middle of the top surface of the pressing block 201 near the left and right ends. The top surface of the pressing block 201 abuts against the bottom surface of the base plate 101 and the top surface of the pressing block 201.

[0036] The connecting and fixing structure includes a U-bolt 301, and the main cable 302 is installed at the bottom end of the outer surface of the U-bolt 301.

[0037] By setting up the pressing limiting structure and the connecting and fixing structure, the nut 105 is threadedly connected to the U-bolt 301, so that the main cable 302 is pressed and positioned by the pressing block 201, and the main cable 302 is limited by the limiting block 202, so that the connection is more stable.

[0038] When the nut 105 is threadedly connected with the U-bolt 301, and when the photovoltaic panel 1 is clamped and connected by the bottom plate 101 and the upper plate 103, the bottom plate 101 presses the pressure block 201 downward, so that the pressure block 201 is abutted against the main cable 302, and the main cable 302 is connected and positioned by using the arc at the bottom of the U-bolt 301 and the arc groove in the middle of the bottom surface of the pressure block 201, thereby completing a stable connection between the photovoltaic panel 1 and the main cable.
