Abstract

The invention discloses a light-gathering aiming device for a tower-type solar thermal power generating system. The device comprises laser beam generators, a light-collecting projecting mechanism and a projection driving mechanism, wherein the laser beam generators are fixedly arranged on solar light collectors around a high tower, and are positioned at the rotation centers of reflecting mirrors of the solar light collectors; the laser beam generator on each solar light collector emits laser beams aiming at a high tower solar energy stove in turn; the light-collecting projecting mechanism and the projection driving mechanism are arranged near a laser beam light path; the light-collecting projecting mechanism is a projecting reflecting mirror or a refracting mirror; while the laser beam generators are emitting laser beams, the projection driving mechanism drives the light-collecting projecting mechanism to move onto the light path of the laser beams; and the laser beams are reflected or refracted onto a light detection screen through the light-collecting projecting mechanism.

Description

technical field [0001] The invention relates to a tower-type solar thermal power generation system, in particular to a light-concentrating aiming device of the tower-type solar thermal power generation system. Background technique [0002] The solar thermal power generation system does not consume fossil energy and emit no pollutants. It is a clean energy utilization system in harmony with the ecological environment. At present, trough, tower and dish solar thermal power generation systems are also valued by countries all over the world, and work is being carried out actively. The tower system has initially shown its advantages due to its large scale, small heat loss and high temperature. [0003] The tower solar thermal power generation system is mainly composed of four parts: concentrating system, absorption and heat exchange system, heat storage system and power generation system. The concentrating system includes reflector, supporting structure, transmission device and ...
