Description
Technical field
The present invention relates to the solar groove type beam condensing unit, specifically is a kind of novel slot Salar light-gathering speculum and support.
Background technology
At present, the development of solar energy optical-thermal field is swift and violent, and sunshine is converged and make it to be converted into heat energy, and being used to promote steam engine or gas turbine power generation will be the important directions that following solar energy utilizes.
That the solar light-heat power-generation system mainly contains is tower, dish formula and three kinds of solar energy systems of slot type.Tower photo-thermal solar energy system makes the lifting of its photo-thermal conversion efficiency and generating efficiency be restricted owing to there is the cosine losses of sunshine, and the tower type solar system also is in an experiment stage at present, also fails to drop into commercial the application.Though cosine losses can be eliminated by regulating dish face direction by the disc type solar energy system, improve solar energy utilization rate, but common tracking mode can make also moving with the dish face of focus, this has just proposed higher requirement to the aperiodicity real-time tracking of tracking system, thus the application of the disc type solar energy system of restriction greatly.Comparatively speaking, the tank-type thermal power generation system is the most ripe, also is first kind and successfully realizes business-like solar heat power generation system.The groove type solar beam condensing unit is compared with the dish formula, though optically focused compares usually below 100, this enough satisfies the needs of solar energy thermal-power-generating.The groove type solar system is used for the parabolic condenser of focusing sunlight, and processing is simple, and manufacturing cost is lower, realizes standardization easily, be fit to produce in batches, and will be breach and the emphasis that worldwide advances the solar heat power generation system commercial applications in the recent period.Yet traditional groove type solar system does not make full use of the characteristics of parabolic minute surface, and the position of thermal-collecting tube is fixing, but along with minute surface is followed the tracks of sun's motion and rotated.In addition, though the technology that thermal-collecting tube is positioned on the fixed-focus line successfully is used in the linear Fresnel system, the light gathering efficiency of linear Fresnel system is lower than the slot type system.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and makes full use of paraboloidal optics and mechanics principle has been simplified the design of groove type solar beam condensing unit, and has alleviated the novel slot Salar light-gathering speculum and the support of beam condensing unit weight greatly.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of novel slot Salar light-gathering speculum and support, comprise mirror mirror, the mirror mirror framework, bracing frame and support bar, described mirror mirror is fixed together by welding or riveted joint mode and bracing frame, described mirror mirror framework is positioned at the two ends of mirror mirror, connect support bar in the middle of the described mirror mirror framework, support bar links to each other with pedestal by bearing, the junction of support bar and bearing is the focal line (being turning cylinder) of mirror mirror, which is provided with thermal-collecting tube, thermal-collecting tube passes support bar and bearing, described mirror mirror is columniform parabola, its cross section is a parabola, it is characterized in that: the described mirror mirror back side is provided with a backplate, and described backplate and mirror mirror intersection utilize the mirror mirror framework at mirror mirror two ends to fix; Be provided with latticed supporting construction between the described backplate and the mirror mirror back side, latticed supporting construction is provided with advanced composite material (ACM) as cushion with the surface that the backplate and the mirror mirror back side contact, and is provided with mat in the cushion;
The confocal point of the described mirror mirror back side and backplate, the cross section of described backplate and vertical section all are parabola, and the focal length at the paraboloidal focal distance ratio mirror mirror of the backplate back side is smaller;
Described mirror mirror edge is provided with the edge ear;
The support frame as described above two ends are provided with the adjustment device.
The whole device of the present invention has made full use of paraboloidal design feature, when front panel (being mirror mirror) is stressed, can be by the latticed supporting construction between two panels with the stressed backplate that is delivered to uniformly, the stressed of backplate passes to support bar by frame structure, and support bar links to each other with pedestal.Simultaneously the edge of each minute surface sets up the edge ear, has improved minute surface anti-recessed deformation ability when being subjected to local big pressure.In addition, for balance dish face departs from the gravitational moment that center of gravity is introduced in the every day rotary course because during rotation, designed on the bracing frame of two adjustable and balancing devices as for the minute surface two ends.
In addition, backplate is designed to a complete parabolic shape, that is to say that the cross section of backplate and vertical section all are parabola, in order further to strengthen the bearing capacity under the wind-force effect of backplate.
Beneficial effect of the present invention: the present invention has designed two confocal paraboloid surface plate structures, and front panel is as reflecting condenser mirror, and backplate is as supporting stressing device.Heat collector is positioned on the focal line (also being the turning cylinder of minute surface simultaneously) of parabolic minute surface, no matter minute surface is along with how solar motion rotates, it is motionless that thermal-collecting tube all keeps, the present invention makes full use of paraboloidal optics and mechanics principle has been simplified the slot light collection Design of device, and has alleviated the weight of beam condensing unit greatly.
