Workflow of the present invention is: when having the solar radiation light time, drive solar groove type light-condensing and heat-collecting device sun reflection complex (4) by the stepping rotary electric machine (2) of following the tracks of the sun, solar radiation light (7) is followed the tracks of rotation.Sun reflection complex (4), converges on the solar receiver (6) by the solar radiation light that the sun (8) sends by the reflection of parabolic minute surface.The solar radiation luminous energy energy density that is converged is strengthened greatly, goes up at solar receiver (6) and produces high temperature or high-energy, externally realizes effects such as high-temperature heat supply or concentrating photovoltaic power generation, effectively improves the solar energy utilization ratio.
The present invention compared with prior art has following advantage:
1, with monolithic glass by the deadweight direct forming on the paraboloidal sheet metal of optically focused (9), not only process easy, and accuracy height, the optically focused performance of its minute surface is good, reflection ray is easier to concentrate on the receiver.
2, sun reflection complex (4) back is a sheet metal, does easily and supports and transmission, and protect the thin glass-mirror of front easily.The sun reflection complex that is formed by thin glass-mirror of integral body and metallic plate has enough intensity and hardness in the actual motion process.
3, owing to adopt monolithic glass to be shaped, each several part links such as fabrication and installation technology, packed and transported, the examination and test of products have preferable performance.
4, the present invention can be widely used in fields such as solar thermal power generation, solar refrigeration and air-conditioning, solar seawater desalination.
