Description
Technical field
The utility model relates to field of solar thermal power generation, particularly a kind of shape-adjusting device of unit reflecting mirror.
Background technology
Solar energy generation technology is to have the sun power of application prospect to utilize one of mode most, and it is converted to heat energy with sun power, and then is converted to electric energy by focusing, thermal-arrest.For example, tower type thermal generation is to gather sunlight by heliostat, and heliostat mainly plays a part to focus on and reflected sunlight in this electrification structure.
Existing heliostat great majority be by a plurality of catoptrons according to certain being arranged in a combination, the heliostat of the catoptron that adopts monolithic is also arranged.No matter be the heliostat that adopts the polylith or the catoptron of monolithic to form, each catoptron wherein all needs to be adjusted to certain curvature, pitching and orientation angles, light can be reflexed on the heat absorption mouth of setting to guarantee the heliostat through adjusting.
The name of Himin?Solar Co., Ltd.'s application is called: a kind of supporting and shape-adjusting device for reflecting mirror of heliostat, application number is: 200910159996.X, publication number is: the Chinese invention patent of CN101661153, disclose a kind of at least four of mirror back surface that are arranged on and transferred the shape assembly, come the supporting reflex mirror by at least three accent shape assemblies that are arranged on the catoptron periphery, i.e. supported at three point at least, and transfer the shape assembly catoptron that stretches by being arranged on one of catoptron central authorities, more promptly stretch, thereby the glass micro-arc curved surface of accommodation reflex mirror is to guarantee the spotlight effect of catoptron.Use by reality, the catoptron more than 90% can both have reasonable focusing effect.
In realizing process of the present utility model, the inventor finds that there is following problem at least in prior art:
Because above-mentioned supporting and shape-adjusting device exists processing and installation errors, make in the said structure that the height of three strong points at least is inconsistent, cause the flatness of mirror mirror to reduce, and then make that the mirror curvature of each several part is inconsistent on the every mirror, cause the hot spot deleterious after the reflection.And at present only be difficult to judge at least three strong points that or that several strong points existing problems according to the effect of hot spot, so difficulty relatively when adjusting can only be adjusted the height of each strong point, the increase of adjustment time gropingly.At present, the adjustment time of each strong point nearly needed about 10 minutes, and final adjustment effect is undesirable.Owing to can not accurately locate the height of adjusting catoptron, promptly catoptron can not keep smooth before regulating curvature, therefore be in course of adjustment and adjust after be easy to form internal stress, cause the breakage of catoptron.By statistics, the breakage rate of adjusted catoptron is installed at present up to about 25%.
In addition, be subjected to the structural limitations of this above-mentioned supporting and shape-adjusting device, when adjusting mirror curvature, need under reasonable weather, carry out, catoptron is placed in the actual installation position differs place, utilize the light of sunshine to adjust then less than 5 meters.This mode is very directly perceived, and the speed of adjustment is also very fast, and adjusting every mirror approximately needs 1-2 minute.But, if run into rainy weather, just can not carry out adjustment work, cause easily and slow down.
At the problems referred to above, the seminar of Himin?Solar Co., Ltd. also once bought the position scanner, by high-accuracy equipment, the relative position of 10-50 point above the test mirror mirror, analyze by computer software, compare with desirable curvature, find out the in-problem strong point, the in-problem strong point is adjusted, and then scan, analyze once more and compare, with structure desired curvature as much as possible, by the method, can not be subjected to the adjustment mirror curvature of weather restriction.But employing the method need repeatedly be adjusted test repeatedly to every catoptron, and the adjustment time of a catoptron needs 1 hour at least, so there is long shortcoming of adjustment time.In addition, this apparatus expensive approximately needs 300,000 Renminbi, because this equipment is precision optical machinery, mounting condition is also very harsh, is unfavorable for carrying, and inconvenience is used in each engineering.
Summary of the invention
Be subjected to the restriction of weather conditions in order to solve supporting and shape-adjusting device of the prior art, the overcast and rainy problem that can't adjust, and this structure exists and adjusts difficulty, long problem of adjustment time, the utility model embodiment provides a kind of shape-adjusting device of unit reflecting mirror.Described technical scheme is as follows:
A kind of shape-adjusting device of unit reflecting mirror, comprise the accent shape parts that are arranged on the described unit reflecting mirror back side, described accent shape parts comprise that at least four are transferred the shape assembly, wherein have at least one to transfer the shape assembly to be arranged on refuting of described unit reflecting mirror central authorities to connect on the pawl center, remaining transfers the shape assembly to be arranged on the periphery of described unit reflecting mirror, and connect the pawl sway brace by refuting separately respectively and be connected described refuting and connect on the pawl center, described accent shape assembly comprises sucker and adjustable fastener, described shape-adjusting device also comprises at least four adjustable bolts that are arranged on described unit reflecting mirror front, the position of described adjustable bolt is corresponding one by one with the position of described accent shape assembly, described adjustable bolt is connected on the support, and contacts with described unit reflecting mirror by described support.
