Abstract
The invention discloses a high-precision heliostat curved surface adjusting and correcting device. The high-precision heliostat curved surface adjusting and correcting device is used for detecting the angle of a sub mirror of a heliostat. The high-precision heliostat curved surface adjusting and correcting device is provided with at least one angle detector, an adjusting jaw and a control computer, wherein the adjusting jaw is used for adjusting the angle of the sub mirror of the heliostat. When the high-precision heliostat curved surface adjusting and correcting device works, the orthographic projection of the angle detector on the sub mirror of the heliostat is located at the geometric center of the sub mirror of the heliostat, the angle detector emits parallel laser beams to the geometric center of the sub mirror of the heliostat of which the angle is to be adjusted, receives laser beams reflected by the sub mirror and analyzes a light return angle, and then the angle of the reflecting surface of the sub mirror is obtained through the law of reflection. The control computer controls the adjusting jaw to adjust the angle of the sub mirror according to the angle of the reflecting surface of the sub mirror. The measurement precision is high, and system requirements can be completely met due to the fact that detection precision of the high-precision angle detector can reach +/- 0.005 degree.
Description
Technical field
The present invention relates to a kind of high-precision fixed solar eyepiece curved surface and adjust means for correcting.Relate to Patent classificating number F24 heat supply; Cooking stove; Ventilation F24J is not included in the heat generation in other classifications and utilizes the utilization of F24J2/00 solar heat, for example solar thermal collector F24J2/40 control device.
Background technology
In existing tower type solar photo-thermal power generation field, tens to hundreds of heliostats arrive tower top end by sunlight, and top of tower arranges corresponding heat dump, by transform light energy, is that heat energy further carries out electric transformation of energy again, realizes solar electrical energy generation.
Heliostat act as converge sunlight line in system, it is to consist of a series of sub-mirror, this a little mirror not only has the curvature of oneself, the array of sub-mirror, by tilt adjustments, forms again the curvature of heliostat simultaneously, and comparatively speaking, if the heliostat curvature deviation consisting of sub-mirror adjustment is large, can directly cause the deterioration of heliostat focused light spot, thereby the reduction of light gathering efficiency finally affects generating efficiency.How improving the precision of heliostat curvature, is the major issue that tower system faces.
The main method of heliostat curvature adjustment is at present by the monitoring to heliostat focused light spot, each the sub-mirror on heliostat to be adjusted under sunshine.In order to make focused light spot best, conventionally a fixing receiving area need to be set below heat dump, because this region distance heat dump is very near, can be defaulted as the focus that heliostat is assembled, what during adjustment, judge is minimum according to being that heliostat is focused at the hot spot at this place, assert that every sub-mirror all adjust to the right place.Mainly there is following problem in the method:
1, heliostat, only in light normal incidence situation, just there will be the minimum situation of focused light spot, and in reality every day may only have a few minutes to reach to approach normal incidence situation, or there will not be this situation always.When light oblique incidence, have larger inclined aberration, cause focused light spot to become a long and narrow distribution, if now still according to above-mentioned method of adjustment, except meeting, reduce to adjust precision, make outside system effectiveness reduces, irregular due to heliostat curvature, cause the heat flux distribution on heat dump surface also irregular, may cause heat dump hot-spot and the serious consequence damaged.
2, the method is in course of adjustment, and reflection ray is used will aim at region of acceptance, so heliostat, in a dynamic running, is adjusted in this case, easily occurs unnecessary security incident.
3, due to common heliostat with the distance of tower all 100 meters of left and right or farther, be difficult to observe focused light spot effect, cause alignment error increase.
4, this adjustment mode can only be carried out when having light, and regulated efficiency is low.
Except above-mentioned adjustment mode, also has at present a kind of method of adjustment, it is the adjustment of reflective picture target, its method is placed on heliostat the place ahead for making one as target, at CCD of set positions far away, by CCD, observe the picture as target of the surface reflection of heliostat, as corresponding every sub-mirror on target have oneself independently as, adjusting every sub-mirror makes to meet theoretical requirement at the picture of CCD place observation, although the method is a kind of problem of 1,2,4 of adjusting mode before having avoided, also brought some new problems:
1, in order to reach higher adjustment precision, conventionally CCD and heliostat apart from meeting more than 50m, picture target and heliostat distance are also more than 10m, cause and take up room greatly, the eyeglass at Jing Chang center is vulnerable to mutual the blocking of eyeglass of adjacent heliostat when adjusting, cause cannot adjust or regulated efficiency low.
2, the precision of adjusting needs human eye to judge by image, and subjectivity is strong, and error is large.
3, each different heliostat curvature needs to make corresponding picture target, and heliostat field may exist 10 kinds of above curvature conventionally, causes picture target quantity many, and cost increases.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of high-precision fixed solar eyepiece curved surface of development is adjusted means for correcting, for detection of settled date mirror mirror angle, has: at least one angle detector, the adjustment pawl that regulates settled date mirror mirror angle and control computer;
During work, angle detector is positioned at the geometric center of settled date mirror mirror in the orthographic projection of settled date mirror mirror; Angle detector, to the settled date mirror mirror geometric center transmitting parallel laser light beam of angle to be adjusted, receives the laser beam by described sub-mirror reflection, analyzes light echo angle, draws the angle of sub-mirror reflecting surface by reflection law; Described control computer, according to the angle of described sub-mirror reflecting surface, is controlled and is adjusted the angle that pawl regulates sub-mirror.
Also there is angle detector fixed mount, by described angle detector be fixed on settled date mirror mirror to be detected directly over; While guaranteeing work, angle detector is positioned at the geometric center of settled date mirror mirror in the orthographic projection of settled date mirror mirror.
Described angle detector fixed mount is a slide rail through the whole sub-mirrors of heliostat top, and in testing process, described angle detector moves on slide rail, pass through successively heliostat whole sub-mirrors directly over position.
