The ability to influence the environment. Due to the great demand for heliostats in tower-type photothermal power stations, considering the weather resistance and mechanical strength of heliostats, it is of great significance to design a lens support structure with good quality and strength.
目前在用的定日镜镜片支撑结构,虽能满足一般项目的需求,但应用于大面积的定日镜上时,对定日镜聚光性能影响很大,因此仍有优化改进的空间。The heliostat lens support structure currently in use can meet the needs of general projects, but when applied to a large area heliostat, it has a great influence on the concentrating performance of the heliostat, so there is still room for optimization and improvement.
