Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of new structure, makes the high cup dolly formula heliostat whirligig of its fastness, reliability and tracking accuracy.
Technology contents of the present utility model is that a kind of cup dolly formula heliostat whirligig is characterized in that it comprises pedestal, cup dolly, vertical rotation axis transmission case, tripod, horizontal rotating shaft transmission case, rolling lead screw, rocking arm, horizontal rotating shaft and mirror holder; Cup dolly is installed on the pedestal, and the vertical rotation axis transmission case is installed on the pedestal of cup dolly lower end; The rotation of cup dolly has constituted azimuthal adjustment; Tripod is installed on the cup dolly, and horizontal rotating shaft is sleeved on the tripod by axle sleeve, and the horizontal rotating shaft transmission case is hinged on the tripod; rocking arm is fixed on the horizontal rotating shaft; the horizontal rotating shaft transmission case is connected with rocking arm by rolling lead screw, and the rotation of pulling horizontal rotating shaft has constituted the adjustment at the elevation angle.
For the tracking accuracy that improves cup dolly formula heliostat whirligig is direct-connected in the rotating shaft of cup dolly a photoelectric encoder arranged, one photoelectric encoder is installed on axle sleeve, the angle that horizontal rotating shaft and cup dolly rotate can both detect with photoelectric encoder, in order to closed-loop control.
The advantage that the utility model is compared with prior art had is:
1, fastness of the present utility model and reliable high.
2, transmission accuracy height of the present utility model and dirigibility are good.
3, tracking accuracy height of the present utility model.
Four, description of drawings
