The invention discloses a solar energy trough-type light-gathering device for fixing focus lines, and relates to a solar energy trough-type light-gathering device, comprising a reflection mirror plane, a reflection mirror plane frame, support rods and a base seat, wherein, the support rod is connected with a stepped motor. The light-gathering device is characterized in that the reflection mirror plane is fixed with the reflection mirror frame in a welding manner or in a riveting manner; the two ends of the reflection mirror plane and the middle part thereof are provided with the support rods; the support rod in the middle is connected with the base seat through a bearing and a rotating valve to form a rotary shaft of the reflection mirror plane; and the focus line, namely the rotary shaft of the reflection mirror plane is provided with a heat collecting pipe which penetrates through the support rod in the middle part and the bearing. In the invention, the characteristics of parabolic reflection mirror plane are utilized to lead the water heater to be placed on the focus line of the reflection mirror plane, thus the heat collecting pipe keeps not to move no matter how the plane to rotate along with the movement of the sun; and in addition, a mould pressing technique is adopted to lead the whole mirror plane to become a continuous whole, thus the mechanical properties of a paraboloid can be utilized to simplify the support structure of the reflection mirror plane, thereby greatly lightening the weight of the light gathering device.
Description
Technical field
The present invention relates to the solar groove type beam condensing unit, specifically is a kind of solar groove type beam condensing unit of fixed-focus line.
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 is owing to exist the cosine losses of sunshine, makes its photo-thermal conversion efficiency, and the lifting of generating efficiency is restricted, 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, and the optically focused ratio is usually below 100, but this enough satisfies the needs of solar energy thermal-power-generating.The groove type solar system, the parabolic condenser processing that is used for focusing sunlight is simple, and manufacturing cost is lower, realizes standardization easily, is fit to produce in batches, 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 structure to simplify relatively, and the overall control of being convenient to computer realizes real-time solar tracking.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of solar groove type beam condensing unit of fixed-focus line, comprise mirror surface, the mirror surface framework, support bar and pedestal, described support bar is connected with stepper motor, it is characterized in that: described mirror surface passes through welding or riveted joint mode and mirror surface frame fixation together, described mirror surface two ends and centre are connected with support bar, middle support bar links to each other with pedestal by bearing and rotary valve plate, form the turning cylinder of mirror surface, on the focal line (being turning cylinder) of mirror surface, be provided with thermal-collecting tube, support bar and bearing in the middle of thermal-collecting tube passes.
Described mirror surface adopts mould once to suppress and forms, and its cross section is a parabola.
Heat carriers such as oil or salt are housed in the described thermal-collecting tube.
Described mirror surface edge is provided with the edge ear.
Described mirror surface framework two ends are provided with balancer.
Described pedestal adopts the bridge pier type structure.
Entire emission minute surface of the present invention adopts mould once to suppress and forms, make the entire emission minute surface form an integral body like this, such mirror surface can carry certain external force, and external force is transferred on the support frame at minute surface two ends, and then guarantees the stressed of whole minute surface; 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, and in addition, support bar is connected with stepper motor, can follow the tracks of the variation of sun altitude with assurance device.
Beneficial effect of the present invention: the present invention has made full use of the characteristics of reflective minute surface, heat collector is positioned on the focal line (also being the turning cylinder of minute surface simultaneously) of mirror surface, no matter minute surface is along with how solar motion rotates, it is motionless that thermal-collecting tube all keeps.In addition, adopt compression molding techniques to make whole minute surface become a continuous integral body, can make full use of the supporting construction that paraboloidal mechanical property has been simplified mirror surface like this, thereby alleviate the weight of beam condensing unit greatly.
