AI Technical Summary

Technical Problem

The existing heliostat main beam assembly has a complex and costly manufacturing process, and is susceptible to corrosion in outdoor environments, affecting structural strength and service life.

Method used

The base material is steel columns or hollow steel pipes with a yield strength of 275-620 MPa. The outer surface is covered with an anti-corrosion coating and an anti-corrosion paint layer. Only the anti-corrosion paint layer is sprayed on the connection area to avoid overall hot-dip galvanizing treatment. It combines a double layer of protection with a zinc-aluminum-magnesium coating and a zinc-rich primer layer.

Benefits of technology

Simplify manufacturing processes, reduce production costs, improve corrosion resistance and structural stability, extend service life, and reduce maintenance difficulty and costs.

Abstract

This invention provides a main beam assembly for a heliostat, a heliostat, and a method for manufacturing the main beam assembly. The main beam assembly for the heliostat includes a main beam structure and a connecting structure. The main beam structure includes a main beam substrate, an anti-corrosion coating, and an anti-corrosion paint layer. The outer surface of the main beam substrate has a coating area and a connecting area, with the coating area covered by the anti-corrosion coating. The main beam substrate is a steel column or hollow steel pipe with a yield strength greater than or equal to 275 MPa and less than or equal to 620 MPa. The connecting structure is directly or indirectly installed in the connecting area and includes multiple connectors. The connecting area includes multiple sub-regions, each sub-region having at least one connector installed. The surface of the area in each sub-region not occupied by connectors is covered with an anti-corrosion paint layer. This method maintains the geometric and assembly accuracy of the main beam assembly, eliminating the need for secondary processing or correction, simplifying the manufacturing process, and reducing production costs.
