AUTOMATIC DEVICE FOR CONCENTRATION OF SUN RAYS ON STATIONARY OBJECT Russian patent published in 2011 - IPC F24J2/54 

FIELD: machine building.

SUBSTANCE: device consists of clock mechanism, of bracket-base, of pair of gears connected with balancing arm, of roller, of lever and concentrator with their common rotation axis and of radiation detector. Rotation velocity of the concentrator should be 4 times slower, than that of an hour hand of clock mechanism to maintain constant reflection of rays on this object. The said condition is ensured with gears and position of axis of rotation of the lever and concentrator. The clock-mechanism is secured on the bracket-base. Rotation from axis of the hour hand is transmitted through a pair of gears at ratio 2:1. On one gear there is secured a roller in sliding engagement with the lever rigidly coupled with the concentrator and having the same rotation axis with it. This rotation axis is on trajectory of roller rotation. In the day time the roller uniformly rotates the concentrator through the lever in direct direction, while at night it interacts also with the bracket-base and with acceleration rotates the concentrator in a reverse direction via one gear, rotation axis of which is deviated with the balancing arm.

EFFECT: direct and reverse rotation of concentrator facilitating automatic many-days operation of device.
