Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic component installation equipment, in particular to an aluminum alloy protective pressing piece of a photovoltaic component with a sealing function. Background Art

[0002] A photovoltaic module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). During the installation of the photovoltaic module, the photovoltaic module needs to be confined to a limit rod, and a pressure piece needs to be installed on the limit rod. The position of the photovoltaic module is limited by the pressure piece. In order to increase the stability of the limitation, an aluminum alloy protective pressure piece for photovoltaic modules with a sealing function has been developed.

[0003] In the existing aluminum alloy protective pressure pieces with sealing function for photovoltaic modules, when the pressure pieces extrude and limit the photovoltaic modules, fastening bolts are installed at the position of the pressure pieces. The fastening bolts drive the pressure pieces to move downward, and the extrusion force drives the pressure pieces to extrude and limit the photovoltaic modules. However, the pressure on the pressure pieces is provided by the fastening bolts. Meanwhile, the photovoltaic modules are exposed to the outdoors. The fastening screws are eroded by rainwater, and the stress generated during use may cause the fastening bolts to crack and be damaged. After the fastening bolts are damaged, the pressure pieces reduce the limitation, and at the same time, the pressure on the photovoltaic modules is reduced. The reduced pressure may cause the photovoltaic modules to slip and be damaged. Summary of the invention

At the same time, when the fastening bolt is damaged, the shrinkage sleeve and the limiting column can continue to be clamped and limited, thereby solving the problems raised in the above-mentioned background technology.
