Description

A fast clamping structure for photovoltaic system

technical field

The invention relates to the technical field of installation of photovoltaic system components, in particular to a fast clamping structure in a photovoltaic system.

Background technique

When installing and fixing solar photovoltaic system components, in order to facilitate disassembly and assembly, increase the speed of installation, and simplify the installation process, many parts need to use snap-fit structures to achieve fixation between adjacent components.

The clamping structure is generally realized by a guide rail and a block that is compatible with the guide rail. For example, when installing a solar panel and a panel bracket, the solar panel is generally pressed onto the panel bracket by a pressing block system. One end of the briquetting structure is in contact with the solar panel, and the other end needs to be clamped on the guide rail on the battery panel support by a clamping structure.

The U.S. Patent Publication No. 20100269447A1 discloses a clamping structure. The clamping structure is mainly provided with internal clamping grooves inside the two side walls of the guide rail, and a convex edge adapted to the internal clamping grooves is provided on the clamping block. During the installation process, insert the convex edge on one side of the block into the corresponding slot, apply pressure to make the block stretch the side wall of the guide rail, and make the other side snap into the corresponding slot. This structure clamps the blocks through the elastic deformation of the two side walls of the guide rail. Although it can be installed quickly, it must be disassembled by prying the two side walls of the guide rail with other tools during the disassembly process. The disassembly process is very cumbersome. In view of the increasingly high labor cost at present, the photovoltaic system adopting this structure will undoubtedly increase the labor cost during the disassembly process.

At the same time, the application document also discloses a card slot on the card block, a card edge structure adapted to the card slot on the guide rail, and the card block is set on the guide rail to realize the card slot and the card edge of the guide rail. Pack. However, when installing this structure, the clamping block must be inserted from one end of the guide rail, and the clamping block must be slid to the installation position for installation. For a longer guide rail, the installation speed of this installation method is slower, so the same Increased installation costs.

Therefore, how to develop a photovoltaic system clamping structure capable of quick installation and disassembly to reduce the installation cost is a technical problem urgently needed to be solved by those skilled in the art.
