Micro-arc curved surface glass collecting mirror of solar heliostat

The present invention relates to a micro-arc curved surface glass collecting mirror, being an important component of a heliostat in a solar condenser system and composed of a micro-arc curved surface forming device and a micro-arc curved surface mirror inclination adjustment device. The micro-arc curved surface forming device is connected to a heliostat frame by the micro-arc curved surface mirror inclination adjustment device; The micro-arc curved surface forming device comprises a substrate, a backplane, a plurality of juxtaposed reflectors and overlappings; The micro-arc curved surface mirror inclination adjustment device comprises reinforcing patches, purlins, and connecting pieces. The angle of inclination of the micro-arc curved surface mirror, relative to the heliostat frame, can be adjusted conveniently according to needs in the invention so that each of the micro-arc curved surface mirror can be combined together to form a complete heliostat. Compared with the existing curved surface glass heliostat forming process, the device provided in the invention has a simple and reasonable structure design, realizes low cost, easy processing and production of a curved surface glass heliostat, being beneficial to the commercialization popularization of tower concentrating solar power generation..
