IMPROVED ROBOT COLLECTOR FOR LARGE LENS SOLAR CONCENTRATORS

摘要

A large composite lens(1) formed of smaller lens segments(2) assembled on supports (11) having pillars(12) refracts concentrated solar rays onto heating coil(3) fitted atop radial arm(4)moving on track (27). High temperature boiling oil in heating coil(3 ) gets heated, flows to insulated hot tank(5) via insulated tubes and then the secondary exchanger(6) for steam, air heating, air-cooling, desalination etc in the same device. Cooled oil goes to cool oil tank (7) for recirculation to heating coil (3). Pumps (19,20) maintain the oil circulation Electronic controls (17)with sun and thermal sensors (18), monitors the system temperature, working, both pumps and cleaning. A top arm (13) with a dust blowing air holes(15) and a motorized rollable cover(14) protects the lens (1) in dust and nights. The radial arm's motor 26 rolls it's wheel 29 on the circular track (27) around central pivot 8 capturing continuous concentrated solar energy efficiently with negligible sun tracking losses. Many lenses form a solar farm.
