A solar panel fastening device

Abstract

The invention discloses a solar panel fastening device comprising a guide rail, a clamping piece, a bolt, a pressing plate and a spring. A clamping block containing groove is formed in the upper end of the guide rail, the upper portion of the clamping piece is a bolt connecting portion, the middle of the clamping piece is two connecting plates arranged symmetrically, a through groove is formed between the two connecting plates, the lower portion of the clamping piece is a clamping block portion, the clamping block portion is matched with the clamping block containing groove, and a spring installation hole is formed in the center of the bottom end of the clamping block portion. The bolt is connected with the bolt connecting portion in a screwing mode and extends into the through groove. The pressing plate is located above the clamping piece and connected with the clamping piece through the bolt. The upper section of the spring is fixedly connected in the spring installation hole. The solar panel fastening device can meet installation requirements of solar panels with different thicknesses, and the installation is easy and convenient.

Description

technical field [0001] The invention relates to a fastening device, in particular to a fastening device for fixing solar panels. Background technique [0002] As the core part of the solar power generation system, solar panels are used to convert the sun's radiant energy into electrical energy. Therefore, solar panels need to be installed outdoors, such as roofs, where they can fully receive sunlight. In order to receive more radiant energy, the surface area of ​​solar panels is large and mostly flat, which is greatly affected by wind, so its fixed installation structure needs to have strong positioning ability and structural strength. [0003] The Chinese patent No. ZL200820102376.3 (publication No. CN201197123Y) discloses a solar panel support structure, which includes a main beam and a block, the main beam has an accommodation space for the block to be inserted, and the block is provided with a The screw hole through which the bolt passes. When in use, the clamping bloc...

AI Technical Summary

Problems solved by technology

The problem with this is that, limited by the height of the accommodation space, the length of the bolts that can pass through the block is limited, so that the adjustable range of the bolts is small. When installing solar panels with different thicknesses, it is necessary to calculate the required bolt length and make corresponding selections. configuration, which is prone to adaptation problems and increased management costs

In addition, when assembling, it is necessary to use tools or fix the blocks by hand to lock the bolts. The installation is complicated and time-consuming.
