AI Technical Summary

Technical Problem

The existing purlin device has a poor fixing effect when fixing the solar panels in the horizontal direction, and is prone to displacement, which affects the assembly effect of the solar panels.

Method used

The hexagonal screw sleeve and transverse positioning block are designed inside the main body of the sandalwood bar. The transverse positioning block is pushed into the tooth groove through the frustum end of the fixing bolt to achieve transverse positioning. The arc-shaped inclined surface and arc-shaped vertical surface are used to improve the smoothness and stability of the screwing, and the elastic ring structure is combined to achieve reset adjustment.

Benefits of technology

It effectively avoids the lateral displacement of the solar panel, improves the fixing effect, ensures a smooth and stable screwing process, and supports flexible adjustment needs.

Abstract

The utility model discloses a novel purline device for a photovoltaic power generation project, relates to the technical field of photovoltaic power generation, and aims to solve the technical problems that the conventional purline device is poor in transverse fixing effect and easy to displace, and comprises a purline main body. Through the designed structures such as the tooth grooves, the transverse positioning blocks and the circular truncated cone end heads, when the fixing bolts penetrate through the solar cell panel and are connected with the hexagonal thread sleeve in a screwing manner, the circular truncated cone end heads at the bottom ends of the fixing bolts push the two groups of transverse positioning blocks to move oppositely along with the penetration of the fixing bolts into the hexagonal thread sleeve; at the moment, a triangular positioning strip of the transverse positioning block can be directly clamped into a corresponding tooth groove in a wingceltis strip main body, so that transverse positioning of the hexagonal thread sleeve is realized, the hexagonal thread sleeve cannot move transversely, and the fixing effect of a fixing bolt and the hexagonal thread sleeve on the solar cell panel is greatly ensured; therefore, the situation of transverse displacement after the solar cell panel is installed and fixed can be effectively avoided.
