Tower light condensing system light condensing reflecting mirror arrangement structure and tracking method thereof

Abstract

The invention provides a tower light condensing system light condensing reflecting mirror arrangement structure and a tracking method thereof. The tower light condensing system light condensing reflecting mirror arrangement structure comprises a rotating device which is horizontally arranged around a receiving device and multiple reflecting components which are arranged on the rotating device, wherein the reflecting components move in a rotating way in the horizontal plane under driving of the rotating device with the vertical line of the central point of the receiving device acting as the axis so that all the reflecting components are enabled to track the azimuth of the sun in a unified way. Each reflecting component comprises a rotating shaft and a reflecting mirror fixedly connected with the rotating shaft, and the rotating shaft is arranged in an inclined way at a fixed angle with the horizontal plane and the vertical plane, wherein the rotating shaft drives the reflecting mirror to rotate so that the reflecting mirror is enabled to track the solar elevation angle and reflect the incident light of the sun to the receiving range of the receiving device. The complexity of a reflecting mirror tracking mechanism can be greatly simplified, the reliability can be enhanced and the cost can be reduced.

Description

technical field

[0001] The invention relates to an arrangement structure of a light-condensing reflector, in particular to an arrangement structure of a light-condensing reflector of a tower-type light-condensing system and a tracking method thereof. Background technique

[0002] The solar tower concentrator power station is generally composed of heliostats, high towers, receiving devices located on the high towers, heat transfer and heat storage systems, and generators. Due to its high concentration multiples, the receiving device can obtain higher The heat collection temperature is widely used.

[0003] Among them, the arrangement structure of the heliostats is generally to install multiple heliostats on a large-scale site, and the multiple heliostats are arranged to form a heliostat mirror field. Since the positions of the heliostats in the mirror field are different , and the spatial position of the sun moves and changes in the two dimensions of altitude and azimuth. In...
