AUTOMATIC SOLAR COLLECTOR WITH FIXED RADIATION RECEIVER Russian patent published in 2013 - IPC F24J2/54 

FIELD: power engineering.

SUBSTANCE: solar collector comprises a drive 1, for instance, a clock mechanism, a gear 2, an annular circuit 3, a lever 4, a concentrator 5 with an axis of rotation 6, a base 7 and a radiation receiver 8. The gear 2, rigidly fixed on the shaft of the drive 1, may move along the outer and inner arcs of the circuit 3 in forward and return directions. This provides for rotation of the concentrator 5 via a sliding joint of the drive 1 with the lever 4, the other end of which is rigidly connected to the concentrator 5, the axis of which 6 is fixed on the base 7. Time of gear 2 movement along the quarter of the circle of the outer arc of the circuit 3 makes 12 hours. For this time the concentrator 5 rotates by 90°. It makes it possible during daytime to continuously forwarded sun rays reflected with the concentrator 5 to a fixed receiver of radiation 8. Circuit configuration is designed so that in case of forward and return travel of the gear 2 the number of rotations is identical, which provides for automatic operation of the solar collector.

EFFECT: simplified design and expanded functional capabilities due to provision of forward and return travel of a concentrator according to a single-stage circuit.
