Description
Technical field
The present invention relates to a kind of High-precision heliostat curved surface and adjust correcting unit.Relate to Patent classificating number F24 to supply
Heat；Cooking stove；The heat that ventilation F24J is not included in other classifications produces and utilizes F24J2/00 solar heat
Utilization, such as solar thermal collector F24J2/40 controls device.
Background technology
In existing tower type solar photo-thermal power generation field, sunlight is arrived by tens to hundreds of heliostats
Tower top end, top of tower arranges corresponding heat extractor, converts light energy into heat energy and is further carried out turning of electric energy
Change, it is achieved solar electrical energy generation.
Heliostat in systems act as assemble sunray, it is to be made up of a series of sub-mirror, these
Sub-mirror not only has the curvature of oneself, and the array of the most sub-mirror passes through tilt adjustments, forms again the curvature of heliostat,
And comparatively speaking, if adjusting the heliostat curvature deviation of composition greatly by sub-mirror, heliostat can be directly resulted in
The deterioration of focused light spot, thus the reduction of light gathering efficiency, finally affect generating efficiency.How to improve heliostat
The precision of curvature, is a major issue facing of tower system.
The main method that heliostat curvature adjusts at present is, by heliostat focused light spot under sunlight
Monitoring, is adjusted each sub-mirror on heliostat.In order to make focused light spot optimal, it usually needs inhaling
One fixing receiving area is set below hot device, owing to this region distance heat extractor is close, can be defaulted as
The focus that heliostat is assembled, the foundation judged during adjustment is the hot spot minimum that heliostat assembles in this place, assert
Every sub-mirror is all adjusted in place.The method is primarily present problems with:
1, heliostat is only in the case of light normal incidence, just there will be the situation that focused light spot is minimum, and real
In border, every day may only have a few minutes can reach close to normal incidence situation, or do not have this feelings always
Condition.When Ray obliquity incidence, have bigger inclined aberration, cause focused light spot to become long and narrow dividing
Cloth, if now remained unchanged according to above-mentioned method of adjustment, except reducing Adjustment precision, makes system effectiveness drop
Outside low, irregular due to heliostat curvature, the heat flux distribution causing heat extractor surface is the most irregular, may
The serious consequence that can cause heat extractor hot-spot and damage.
2, the method is in course of adjustment, and reflection light uses acceptance region to be directed at, so heliostat is in
One dynamic running, in this case adjusts and unnecessary security incident easily occurs.
3, due to usual heliostat and the distance of tower all at about 100 meters or farther, it is difficult to observation focused light spot
Effect, causes alignment error to increase.
4, this adjustment mode can only be carried out having light when, and regulated efficiency is low.
In addition to above-mentioned adjustment mode, also having a kind of method of adjustment at present, the most reflective picture target adjusts, its side
Method is placed on heliostat front for making one as target, sets a CCD in remote position, passes through CCD
The picture of the picture target of the surface reflection of observation heliostat, as every sub-mirror corresponding on target has oneself independent picture,
Adjust that every sub-mirror makes to observe CCD at requires, although this method avoid previous as coincidence theory
Kind the 1 of adjustment mode, 2, the problem of 4, but also bring some new problems:
1, in order to reach higher Adjustment precision, usual CCD and heliostat distance can at more than 50m, as
Target and heliostat distance, also at more than 10m, cause and take up room greatly, and the eyeglass at Jing Chang center is when adjusting
It is vulnerable to mutual the blocking of eyeglass of adjacent heliostat, causes cannot adjust or regulated efficiency is low.
2, the precision adjusted needs human eye to be judged by image, and subjectivity is strong, and error is big.
3, each different heliostat curvature is required for making corresponding picture target, and usual heliostat field there may be
The curvature of more than 10 kinds, causes as target quantity is many, and cost increases.
Summary of the invention
The present invention is directed to the proposition of problem above, and a kind of High-precision heliostat curved surface developed adjusts correction dress
Put, be used for detecting settled date mirror mirror angle, have: at least one angle detector, regulation settled date mirror mirror

Point is fixed with the angle detector described in.
The described pawl that adjusts is the multiple electric cylinders being arranged in the shade described of settled date mirror mirror, with described
Control compunication to connect, by regulating the extension elongation of one or more electric cylinder push rods, adjust the settled date
The angle of mirror mirror.
Owing to have employed technique scheme, a kind of High-precision heliostat curved surface that the present invention provides adjusts correction
Device, compared with prior art, the invention have the advantages that certainty of measurement is high, due to high-precision angle
Degree detector detection precision can reach ± 0.005 °, fully meets system requirements；Equipment occupation space is little, if
Generally within 1m, both in heliostat position, it can be adjusted school for heliostat distance
Just, do not limited by place；The efficiency measured and adjust is high, owing to directly being outputed angle number by display screen
Value, adjustment personnel can directly be adjusted according to numerical value at any time, until the position that meets the requirements；Cost is relatively low,
As long as the sub-mirror distributed architecture of heliostat is identical, can realize sharing, not affected by Curvature varying.Generally
Heliostat field only has the sub-mirror of a kind of form to be distributed, and i.e. has only to a set of.High-precision angle detector
Cost is the highest, and buys easily.
