Description
Affiliated technical field
The present invention relates to technical field of solar utilization technique, specifically a kind of heat collector of collecting solar energy and being used for high temperature heating, hot water engineering and generating.
Background technology
Traditional solar energy luminous energy gatherer generally uses the monomer parabolic concentrator as concentrator, and follows the tracks of the sun by control system, makes the incident direction of sunshine parallel with the minute surface primary optical axis, and the focus of condenser moves along with the motion of condenser.Because receiver is at the focus place, therefore will be along with the motion of focus same moved further.This will produce four big unsurmountable shortcomings.One, receiver can not be excessive, and receiver has blocked the effective area of condenser reception sunlight, influences collection efficiency.In order to reduce the area that keeps the sun off, certainly will to limit the volume of receiver.Its two because the reason of receiver own wt, must strengthen the power that condenser drives.Because lever principle, the driving power that bears receiver weight will become geometric growth along with the height of focal length.They are three years old, traditional solar receiver is in outdoor daylighting, and owing to its focus is along with moving of time changes, so it is not a fixing point, so can't be by the method for conduction, the energy that concentrator is obtained passes to indoor or has the place of certain distance to use.Its four because the position of traditional senior middle school's temperature solar cooker receiver moves, so solar attachment can't adopt the array combining structure, also just can not be used for industrialized utilization or use solar electrical energy generation.Just, above-mentioned unsurmountable reason is restricted owing to making the solar energy utilization.
In order to overcome above-mentioned shortcoming, some experts of China have obtained breakthrough through for many years effort.As number of patent application is the patent application of 200510200037.X and 200610048636.9, has all surmounted prior art in design, but also still can not reach practical purpose.As the patent application of 200510200037.X, receive solar energy in order to reach high accuracy, adopt summer and winter two condensers, adopt the manual adjustments elevation angle simultaneously.But this technology is annual must change condenser twice, but also the condenser deposit of some must be arranged, and has not only increased cost, has also strengthened the management intensity and the difficulty of equipment.In fact, no matter be electricity generation system or hot water engineering system, all there are every year many beam condensing units to need to change, store, its workload and the time of delaying will be difficult to accept.Thus, the practical value of this invention is worth discussion.
Again such as, 200610048636.9 application for a patent for invention, though adopted the design of condenser fixed-focus, but whole condenser but will turn round round focus, and this needs powerful driving force, complex structure, energy consumption is big, floor space is big, and wind loading rating is poor, is difficult to enter the stage of actual exploitation utilization.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this invention is to provide and a kind of condenser has been followed the tracks of a day photomovement rotation around the earth's axis, can the adjusted in concert condenser curvature and the elevation angle, make the light irradiation form the arrangement for synchronously adjusting curvature of fixed-focus and the solar focus-fixing receiving at the elevation angle.
The present invention along with seasonal variations changes this reality, can high accuracy focuses the purpose of reception in order to realize condenser according to the height of the sun, must adjust the curvature and the elevation angle of condenser along with changes of seasons.Studies have shown that, adapt to the sunshine seasonal variations, condenser curvature excursion is also little.The variation at the sun elevation angle only was 1/2nd of a declination angle excursion in 1 year, promptly 23.5 ° (33.25 ° that deduct winter 56.75 of summer is exactly 23.5 °).Spring, day in the Autumnal Equinox, the declination angle was a zero degree, and the condenser inclination angle is 45 degree, and condenser tilt adjustment scope is 45 ° ± 11.725 ° in 1 year.Therefore, the annual amount of adjusting of condenser is smaller, adjusts once just passable every 5～7 days.Key is to find one can change the stress point that condenser curvature is regulated, and just can reach the adjusted in concert to curvature mirror when adjusting the condenser elevation angle.
Simultaneously, the present invention also will use solar energy different latitude of living in to design support according to different regions.Because the user in each latitude area uses the support of condenser, it highly is different.Realize the adjusted in concert of the condenser elevation angle and curvature, corresponding adjustable for height condenser support just must be arranged.
The technical solution adopted for the present invention to solve the technical problems is: the solar focus-fixing receiving at this arrangement for synchronously adjusting curvature and the elevation angle, comprise support, condenser, with a day mechanism, be that mainly said support is by rack sleeve be arranged on the elevating lever that is used to regulate the condenser latitude in the rack sleeve and form; Said condenser is by elevation angle rotating shaft and the hour angle rotating shaft active link that is arranged in the rotating shaft sleeve pipe, the rotating shaft sleeve pipe is connected with the elevating lever of support by rotation angle modulation axle, on condenser, be provided with curvature mirror and regulate anchor point, between hour angle rotating shaft and condenser, be provided with according to curvature mirror and regulate the adjusting rod that anchor point is regulated the curvature mirror and the elevation angle, be provided with elevation angle set screw at the adjusting rod tail end, between the elevating lever of rotating shaft sleeve pipe and support, be provided with latitude angle fixed head; On the extended line of condenser hour angle rotating shaft longitudinal centre line, the optically focused focus is arranged; Describedly be made up of controller, hour angle screw rod, stepper motor, chain, driven sprocket with a day mechanism, stepper motor is connected with the hour angle screw rod, and driven sprocket is meshed with gear on the hour angle rotating shaft by chain; Between condenser lower end and hour angle rotating shaft, be provided with and regulate curvature mirror and the auxiliary adjustment bar at the elevation angle, the set screw of tail end and the connecting rod that is connected with the auxiliary adjustment bar.
The present invention can also be designed to horizontal type structure except vertical structure.
The invention has the beneficial effects as follows:
The one and since with condenser with the position of daily motion and focus on same ground axis, therefore only need to adopt day method of tracking that the luminous energy of condenser is radiated on the energy receiver of focus area all the time.Because energy receiver is fixed, so array is convenient in the present invention, the industrialization energy collecting is used.
The 2nd, condenser has adopted the adjustment mode of variable curvature, greatly reduces cost of manufacture and management cost, has improved practicality, has widened the high-temperature heat-gathering range of application of solar energy.Both can be used as the middle high temperature heat source of family, and be used for hot water, cook, heating; Can be used as hot water, the high-temperature steam of hot water engineering again, be used for processing, oven dry, heating and the generating of industrial and agricultural production.Expanded the field of solar energy high-temperature heat collection as the industrialization utilization.
The 3rd, drive unit has adopted most economical chain sprocket structure and screw rod to be used, and makes condenser follow daily motion to oversimplify, but also has auto-lock function, has improved the wind loading rating of device.And the solar array thermal-arrest is become a reality, reduced production cost effectively.
The 4th, adopted segmental timbering, its base can be regulated length, and increasing stability, and its mobile jib adopts suit lifting syndeton, and the user that can adapt to any latitude uses, and is being convenient to the processing of accomplishing scale production.
