AI Technical Summary
The existing heliostat main beam structure requires welding, which is costly and complex, and cannot address the defect of non-parallel trusses.
The new type of solar thermal heliostat support main beam structure, which does not require welding, includes columns, main beam, tilt adjustment rotary assembly and purlins. The angle of the main beam is adjusted by a motor-driven rotary reducer. The connection is made by clamps and diagonal braces, which simplifies the processing procedures and enables calibration adjustment during installation.
It reduces processing costs, simplifies the process flow, enables parallelism adjustment of the main beam truss, facilitates installation, avoids positioning processing on special machine tools, and improves efficiency.
