Abstract
The invention relates to a system for turning focused sunlight spots into parallel light capable of being transmitted at high density in any direction. At present, solar energy is mainly utilized in two modes, namely focusing sunlight and directly focusing heat, and utilizes solar panels to convert into electric energy. A solar cooker technology is an ideal technological case for focusing sunlight, but has lower power and can only work close to a focus so that the utilization of the solar energy and the development of a solar energy utilization enterprise in a focusing mode are limited. Sunlight at the focus in the solar cooker technology can be transferred to an indoor point for indoor watering and cooking, and the process can be repeated to transfer sunlight in other places to the point so as to multiply the power until limitless multiplication, therefore, sunlight transfer at the solar cooker focus turns to be a key. A half of a revolving paraboloid (namely a concave light-transferring head) solves an initial problem of transferring the sunlight at the focus and converts the focused sunlight at the focus into parallel light rays which can be parallel to a principal axis and can randomly change directions, and afterwards, a flat mirror is utilized to reflect the parallel light rays into the point. The focusing mode collects high energy and finally realizes solar power generation.
Description
Technical field:
Sun power, the energy, Conversion of energy
Background technology:
The utilization of present sun power in the world is mainly to adopt solar panel.So because it costs an arm and a leg and the low slower development of conversion ratio.And the solar cooker technology is not walked with difficulty in its 50 years of development history because its technology content is high yet.The present invention then utilizes the original optically focused technology of solar cooker dexterously, and the optically focused focus of solar cooker is transferred to any one indoor position, can not only open kitchen range and several times of tens times of liftings of power indoor, can make full use of sun power and heat up water, heating, refrigeration, generating.Is electric energy without cell panel with conversion of solar energy, starts to transfer sun power to heat energy, heat energy and transfer the beginning that mechanical energy, mechanical energy transfer electric energy to.Used technology then is the optically focused principle and the direct reflection principle of the paraboloid of revolution.
Summary of the invention:
Imagination: the roof (as Fig. 1 Fig. 2) that present solar cooker (to call optically focused rotation parabolic lens in the following text) on the market is fixed in urban building with support.(the present invention is called 1/2nd parabolic lens concave surfaces changes shaven head at the focus place of parabolic lens (being the sunlight junction) a light conversion head to be installed, be called for short concave surface and change shaven head), to become diameter by the directive that the passes through focus light-ray condensing from all directions that minute surface is assembled less than 2 centimetres of parallel lines light beams, in short distance, changeing shaven head by 90 degree directional lights turns to downstairs, arrive the position that is fit to and change bare headed that beam steering is indoor with 90 degree directional lights again, change shaven head with 90 degree again in indoor suitable position light beam is turned around upwards, this light beam is exactly the blank of indoor solar cooker.Therefore this power is because of through reflection repeatedly with propagated a segment distance in air, and energy consumes to some extent, requires the reflectivity of reflective head will reach more than 95%, and ideal is more than 99%.Present technology can reach this point.In the transmission of air medium and long distance, consume luminous energy, so the vacuum available reflective tube replaces the aerial transmission of light.So how, improve the power of this indoor " solar cooker "? principle is very simple, we return the roof of urban building again, settle 3-5 optically focused rotation parabolic lens (being traditional solar cooker) with power, each is poly-respectively to " optical collector " after parabolic lens changes shaven head to change into directional light, there is optical collector to assemble and commentaries on classics light 90 degree (vertical duction gets final product) downstairs, light transmits in the vacuum reflective tube then, reaches in the resident family, and the power of this moment has reached 3000 watts-5000 watts power.Can regulate collection area at any time as required.Thereby the power behind the adjustment optically focused.
Because the raising of power, this " solar cooker " just can do any cooking.All the other times then feed light photo absorption performance preferably in the boiler, can water is boiled, drinkable, have a bath, warm oneself, freeze, can replace popular solar vacuum heat-collecting pipe water heater at present so fully, " solar cooker " cause of finishing is by the transformation of rural area to the city.
This is the first step of invention, on this basis, following content has just been arranged:
Boiler (or claim solar boiler): built-in photo absorption performance is the light absorption pipe made by alloy of multilayer multiaspect (face is coarse) or the plate of interior sky preferably, light is upwards injected by lower opening, reflect, scatter to the tube inner chamber from multiple angles, in the hope of reaching the abundant and fast Absorption of light.
This described boiler arrangement is fixed on the wall, because of it has the function of heating up water, so claim " wall-hung boiler ".
The solar-powered high-pressure steam boiler:
The design boiler is the many wall types of multilayer, promptly increase the number of plies of boiler wall, enough big space (subpattern of similar chest casing) is arranged between every layer, every layer can both be born 5 air pressure above (bearing pressure capability is the bigger the better), between layer and the layer pressure valve is arranged, outermost layer adds one deck vacuum layer again, and inwall does the reflection horizon with minute surface, in the hope of insulation.The inner most steam of boiler breaks through behind the pressure valve following one deck (the being balance layer) inner accumulated at it.The balance layer pressure inside constantly raises, reach that pressure valve that steam behind the certain pressure breaks through balance layer rushes at next balance layer again and in layer inner accumulated, class is urged successively, because have " balance layer " to come the high pressure of one deck in the balance between layer and the layer, so when layer 5 reaches 5 air pressure, innermost layer has reached 25 air pressure, and temperature is very high.This is branch mailbox layer-stepping pressure heat insulating container just, just the solar-powered high-pressure steam boiler of our requirement.Because it has had heat-insulating property, therefore can be described as the storage of solar energy system.
Solar generator:
The above is when energy each layer inner accumulated in high-pressure boiler of sun power.When needing generating, open the valve of outer one deck step by step, because all have pressure differential between each layer, one deck steam sprays to skin fast in making, revolving wormgear is installed at the spout place, and the gas of Pen Sheing just can promote the turbine rotation like this, and the turbine rotation drives the magnetic pole rotation, this duration one lead is in inside, magnetic field, and lead just has voltage power output.The blank of Here it is solar generator.Steam sprays between case and case, can improve energy transformation ratio and recycle number of times.

Embodiment
Crucial part of the present invention is that the sunshine that will assemble " leads " place of arriving our needs.The first step is the most key to be that " solar cooker " focus place sunlight is become directional light.Directional light then can change light walking along the street footpath with flat mirror reflects.
The characteristics of known rotation parabolic minute surface: the parallel rays that is parallel to paraboloid of revolution axis of symmetry is gathered in a bit after direct reflection.It is focus.Otherwise, after paraboloid of revolution reflection, become the parallel rays that is parallel to axle through the light of overfocus.That original solar cooker is used is the former, and we mainly emphasize the latter.In a bit, the latter then becomes directional light to light again solar ray collecting for the former.So " concave surface changes shaven head " also is rotation parabolic minute surface.Just size, the curvilinear equation of it and the optically focused paraboloid of revolution are different, but focus that must two paraboloids of revolution overlaps at the practical application position.Illustrate: 2 square metres of design collection area, 1.6 meters of diameters, focus is to the optically focused parabolic lens of 1 meter of the distance of initial point, then the curvilinear equation of trying to achieve it with mathematical method for " X square equal 4Y " (Fig. 6), if the concave surface that designs above it changes shaven head commentaries on classics light beam diameter afterwards less than 2 centimetres, focus is to 0.5 centimetre of the distance of initial point, then tries to achieve concave surface with mathematical method and changes bare headed curvilinear equation and be: " X square equal 2Y " (accompanying drawing Fig. 6 demonstration).If the design beam diameter is littler, then the accuracy requirement of concave surface commentaries on classics shaven head and optically focused parabolic lens is higher.Changeing the bare headed directional light that changes into through concave surface can be through flat mirror reflects to any old place.Also this directional light can be reassembled by other optically focused rotation parabolic lens and level crossing as light source.
Optically focused rotation parabolic lens: the concave surface that para-curve Rotate 180 degree obtains is made minute surface, in promptly traditional " solar cooker " " optically focused pot "
Concave surface changes shaven head: also claim 1/2nd rotation parabolic lens, have para-curve to revolve to turn 90 degrees to obtain profile that concave surface is made minute surface.
Optical collector a: length of side is equaled 6 centimetres of alloy sheets curve 3 rectangular blocks that 120 sizes of spending angles are equal to, plate reflectorized material above or stick reflective membrane, reflecting rate is reached more than 99%.A support is welded at the back side.Can follow the tracks of the sun synchronization rotation.(Fig. 3)
The vacuum reflective tube receives the light beam that come by the optical collector reflection, with light ray propagation to requiring the position.When processing (simple and easy vacuum tube can omit).
90 degree change shaven head and light beam are sent into indoor.It becomes miter angle with the high level crossing of reflecting rate (reaching more than 99%) with vertical direction.
Light beam feeds extinction, and boiler insulation, high voltage bearing is when the rising of water tank internal cause temperature reaches several atmospheric pressure, open pressure valve and blow the turbine rotation, drive the magnetic pole rotation, its inside conductor then has electric current output, this just easy solar generator, the front is existing to be introduced.
Above-described key is outside the focus of optically focused rotation parabolic minute surface concave surface to be installed to change shaven head, is able to transfer the light at focus place to parallel beam.In fact also have another kind of commentaries on classics shaven head, rotate the parabolic lens convex surface exactly and change shaven head, the installation site that it and concave surface change bare headed is different, and concave surface changes shaven head and is installed on outside the focus of optically focused parabolic lens, and concave surface changes shaven head and then is installed in (Fig. 7) within the focus.Utilize its convex surface (convex surface is made minute surface to be installed between optically focused rotation parabolic lens focus and the initial point) reflection to reflect and next light by the optically focused parabolic lens, the focus of two parabolic lens is overlapped, be parallel at sunray under the prerequisite of axis of symmetry, then its folded light beam is the axis of symmetry of the optically focused paraboloid of revolution just.Dig at its initial point place an aperture then light beam appear.Next connect a vacuum reflective tube, change the light device, make light beam parallel to the ground, light beam is delivered to desired location by one degree of freedom.
Convex surface changes shaven head: the convex surface of the paraboloid of revolution is coated with reflector layer, is installed in optically focused rotation parabolic lens focus between the initial point.(Fig. 7)
Degree of freedom is changeed shaven head: fix a plane minute surface with helical mount, regulate the bolt height, make minute surface become 0-90 degree angle (just enough in the general miter angle) with level angle
Regardless of what mode,, more complicated in the practical application if off-axis focuses on the meeting of calculating according to the parallel relation of the on-site latitude of user and parabolic axis of symmetry of time adjustment optically focused and sunshine.But must guarantee the synchronous rotation relationship of optically focused rotation parabolic lens, commentaries on classics shaven head and the optical collector three and the sun.Can design an integrated chip controls.
