AI Technical Summary

Technical Problem

The existing photovoltaic module support system requires the production of two different sizes of purlins, which results in high production costs. Furthermore, when the connection length is long, the top of the purlin is unstable, affecting the ease of installation.

Method used

A purlin structure for a photovoltaic module support is designed, which achieves adjustable splicing and enhanced strength of the purlins through the movable insertion of the filling end and the plug end, combined with the threaded connection of the side hole and the bottom hole.

Benefits of technology

It enables flexible adaptation of the purlin structure to different photovoltaic module sizes, has good stability during combined extension, avoids instability at the top of the purlin, improves connection strength, and facilitates installation.

Abstract

The utility model discloses a purline structure of a photovoltaic module support, which comprises a purline, one end of the purline is provided with a filling end, the other end of the purline is provided with an inserting end, the inserting end of the purline is movably inserted into the top end of the filling end of the other purline, the bottom end of the inserting end is provided with a bottom groove, and the top end of the inserting end is provided with a bottom groove. And the filling ends are movably clamped into the bottom groove. According to the utility model, the insertion end is inserted into the top end of the surface filling end of another purline, so that a plurality of purlines are combined and connected with one another, the device can be adapted to photovoltaic modules with different sizes to be spliced and combined for use, and meanwhile, the device can be conveniently combined and extended; the surface of the top end of the purline is not higher or lower during combined extension, and the fixing table can be mounted in the bottom holes at different positions according to the position of the main beam, so that the device can adapt to the mounting positions of the fixing table at different positions of the main beam, and the device is convenient to use.
