Description

Device for manufacturing heliostat mirror surface curvature
Technical Field
The utility model relates to a heliostat processing tool, in particular to a device for manufacturing the mirror surface curvature of a heliostat.
Background
The tower type photo-thermal technology utilizes thousands of heliostats to focus sunlight on a heat absorber arranged at the top of a heat absorption tower, heats a heat transfer medium and converts solar energy into available high-grade heat energy. The sun tracking and focusing of the heliostat become one of key technologies of tower type photo-thermal utilization, the heliostat can reflect sunlight to a specific position on the heat absorber through real-time sun tracking, and the shape and the size of reflection light spots greatly influence the distribution of the light spots on the heat absorber and the cutting efficiency of the heat absorber.
With the high parameter and large capacity of the tower type photo-thermal commercial project, the field area of heliostats and the arrangement height of heat absorbers are greatly increased, and taking a 100MW photo-thermal power generation project as an example, the horizontal distance from the furthest heliostat to the heat absorber tower is more than 1000 meters, the central height of the heat absorber is 210 meters, and the distance from the heliostat to the central position of the heat absorber is more than 1020 meters. Because the sun rays actually have a certain cone angle, the light spots reflected by the planar heliostat are spread in long distance and then are dispersed into light spots with larger areas, and if the light spot areas are larger than the sections of the light receiving surfaces of the heat absorbers, certain energy loss can be generated, so that the cutting efficiency of the heat absorbers is reduced.
When the concave heliostat is adopted in the heliostat field, the curvature radius of the heliostat can be determined according to the position of the heliostat away from the heat absorber, sunlight is focused on the heat absorber, the size of reflection light spots of the heliostat is reduced, and the cutting efficiency of the heat absorber is improved. Thus, there is a need to produce heliostats with a certain curvature. The existing heliostat production process is flat mirror type, the production cost of the concave mirror is high, and the design and production requirements of a large-scale heliostat field cannot be met. There is a need for a convenient and efficient device for manufacturing concave heliostats that addresses the shortcomings of the prior art.
