Description
Technical field:
The present invention relates to technical field of solar utilization technique, exactly it is a kind of plastics transparent type solar energy condenser.
Background technology:
The energy is the requisite material of human lives, and the kind of the energy is a lot, as: oil, coal, rock gas, nuclear energy etc.But oil, coal, this class natural energy resources of rock gas always have exhausted that day, though nuclear energy efficient height, service time is long, needs huge investment, in case very harmful to the mankind of having an accident.Sun power is a kind of inexhaustible, nexhaustible energy, and environmentally friendly, is subjected to various countries scientist's attention in recent years.
Human use's sun power has history remote, as: burning plant, coal, oil, rock gas etc., that is an indirect utilization sun power.Directly utilized modern age the technology of sun power that photoelectric cell, solar water heater, solar cooker, solar turbine power station etc. are arranged.But because the energy density of sunshine is low, temporal intermittence stores difficulty or the like significant problem and is not effectively solved, and people utilize the situation of sun power not form as yet on a large scale.Wherein main cause is that solar cell power is too little, and cost is too high, still can not popularize civilian.In recent years solar water heater has obtained significant progress, and technology reaches its maturity, and has formed the industry of considerable scale gradually.But the shortcoming of solar water heater is to produce hot water, can not produce boiling water and steam, and it is used future and has a greatly reduced quality, and not fully up to expectations regretting arranged.Solar cooker is in the low state of development especially.Once had solar cooker heat both at home and abroad the end of the seventies beginning of the eighties, and people did a large amount of trial experiment, and the solar cooker of being reported is most to be that reflection type mirror condenser, its fatal weakness are that to connect light area little, and the heat of generation can not satisfy people's daily demand.In addition, solar cooker can only be operated in the open, and wind, sand, low temperature make the thermal efficiency of solar cooker lower.Once more, solar cooker is following, and the luminous energy absorption plant is pedaled and climbed down last, and operation is extremely inconvenient, and the sunshine tracking problem is also outstanding more.In fact, the solar cooker of existing structure by people is negated.
Once report dull and stereotyped transmission-type Fresnel spotlight the eighties, not a whoop and a holler as mirror reflection condenser, analyze its reason, may cost an arm and a leg for light transmissive material at that time, dull and stereotyped Fei Shi condenser rigidity is not enough, easily causes scattering, complex structure, handle inconvenience, so that do not have bigger substantial progress.China Patent No.: 96242005 disclose the utility model patent that a kind of name is called " indoor multifunctional solar stove ", China Patent No.: 99228183 disclose the utility model patent that a kind of name is called " glass vacuum solar collector tubes condenser ", and their structure all is traditional forms.Patent 99211497.7 umbrella shape transparent type solar energy kitchen range optically focused principles also are the Fresnel prism refraction principles, but its statement is unclear, its prism bottom surface is expressed as the cylinder with the minute surface parallel axes, rather than allow the conical surface of all refracted rays by focus, thereby reduce light gathering efficiency more than at least 7%, its structure has difficulties on the implementation, and practicality need be explored.
Summary of the invention:
The purpose of this invention is to provide a kind of transparent type solar energy condenser, in order to big-power solar to be provided.Its optically focused principle comes down to a kind of improvement of dull and stereotyped Fresnel spotlight.What at first, it utilized is a series of prism refraction principle.The prism plane of incidence and plane of refraction angle are bigger, the refraction angle is bigger, in a plane, the corner dimension of prism is relevant with its present position in the plane, and principle is that the light of prism its refraction of optional position in the plane makes on its focus that projects this level crossing all the time.Focal length is also relevant with the prism angle, and the angle of the prism of same position is bigger in the plane, and focal length is shorter.Designing requirement is with the transmittance height in a word, and handiness is a main idea.Secondly, transmission-type condenser main points of the present invention are to have utilized sphere optically focused principle.Its plane of incidence of each prism is the sphere shape or the cylinder shape of same curvature, its plane of refraction is a planar shaped, the sunlight that is reflected will converge on the singular point that is called as focus, can obtain the maximum ratio that focuses on, and this is the inaccessiable focusing index of classic flat-plate Fresnel spotlight.Utilize condenser of the present invention, focus temp surpasses thousand degree, can be used for cutting, welding, melt various metals, does various scientific experiments.Once more, why transmission-type condenser of the present invention selects sphere shape or cylinder shape concentration structure to be because this structure has the highest rigidity of structure, and the starting material consumption of economizing most makes caustic have minimum scattering, thereby improves the sunlight energy that converges to focus.The 4th, the used light transmissive material of condenser of the present invention is not traditional glass.But replace with transparent plastic, the transparent plastic kind is more and more at present, and price is more and more lower, and this is the progress in epoch, also is the material base that the present invention can be successful.Plastics are inexpensive, are easy to machine-shaping, light weight, and flexible is easy to bonding reparation.Transparent plastic sheet places mould to add thermal deformation and makes it simultaneously become local bright and clean sphere shape (or cylinder shape) another side to be molded into a series of concentric rings (or straight line plane), each concentric ring all is pressed into planar shaped, each concentric ring and spherical outside surface constitute the prism of a series of different angles, the sunlight of all prismatic refractions all converges on the focus of this sphere, and contemplated curved surface solar panel is promptly accused and finished.Also can achieve the above object with the injection moulding way equally.One mold can mold pressing go out ten million transparent plastic curved surface solar panel.Little toy for children, the teaching appliance of arriving of size that condenser of the present invention is related arrives volleyball court, basketball court big scale like that greatly, even installs the series, parallel use like tens hot houses, forms genuine sun power field.Each large-scale beam condensing unit is equivalent to a miniature boiler.The 5th, the processing of condenser condenser mirror of the present invention has been adopted and has been cut apart the block method, no matter how huge condenser mirror, and its optically focused principle is identical, has only and could produce large-scale at an easy rate or the ultra-large type condenser mirror with machine tool with cutting apart the block method.This is another theoretical foundation of the present invention.
Concrete structure of the present invention is as follows:
With reference to the accompanying drawings 1, it comprises condenser mirror, support, absorption installation of heat energy, energy conversion device and tracking means.Condenser mirror all is sphere shape or a cylinder shape with diameter to sunlight one side, the focusing one side all is the planar shaped of a series of concentric annular or the planar shaped of straight line, condenser mirror (1) is to be combined by polylith, be installed on the sphere shape support frame (2), sphere shape framework (2) is fixed on the truss (3), truss (3) is installed on the condenser broadwise tracking axis (4), condenser broadwise tracking axis (4) is installed on the warp-wise turning axle (7) by U-shaped support (8), warp-wise turning axle (7) is installed in condenser support (9), (10) on, in truss (3) bottom luminous energy absorption plant and heat-absorbing medium (12) are housed, are connected on the thermal energy conversion device (16) by heat-absorbing medium conduit (13).Condenser mirror (1) is made for transparent material.Be connected with pitman shaft (5) between truss (3) and the condenser broadwise tracking axis (4).Warp-wise tracking axis (7) is equipped with in U-shaped support (8) below, and warp-wise tracking axis (7) is contained in warp-wise and follows the tracks of on the bearing assembly (10).Luminous energy absorption plant (12) outside surface is equipped with muff (11).Safety valve (14), alarm (15) and hydrothermal solution valve (17) are installed on the thermal energy conversion device (16).
Advantage of the present invention is of many uses: the plastics transparent type solar energy condenser thermal power of a diameter of phi 3m-Φ 5m can satisfy the average family energy fully between 4-12kw, as heat up water, cook, warm oneself, generate electricity, freeze, dry or the like purposes.Another advantage be condenser last, the luminous energy absorption plant can be made into the in-house operation formula down, has overcome the drawback of the open-air operation of reflection type mirror solar cooker.No matter be that the reflective type solar kitchen range all can't be comparable with these plastics transparent type solar energy condenser from power, on the cost, in the operation.The solar energy metric density is low, this is an objective fact, in order to obtain enough solar energies, must increase the light area that connects of condenser as far as possible, but excessive area will be unfavorable for the mould manufacturing, transportation is installed also inconvenient, at this problem, the present invention utilizes minute surface block split plot design that the condenser minute surface is resolved into several portions, and each part promptly is named as the curved surface solar panel, relevant curved surface solar panel is spliced on the steel spherical frame successively by designing requirement, finish the condenser mirror assembling.The steel spherical frame is connect by the metal boom mutually with the luminous energy absorption plant that places focus, constitutes relatively-stationary optically focused one thermal absorption device.This device is connected with the support that ground is fixed by bearing or universal joint, makes it carry out two dimension easily and rotates, and is used to follow the tracks of sunshine.

(b). " sunlight thermal absorption part ": be important component part of the present invention.Form by figure number (11), (12), (13).(12) be that a luminous energy absorbs container, comprise intensions such as photo-thermal conversion and thermal energy storage medium, the heat absorption container is placed on the focus of condenser, can adopt traditional adiabatic black matrix absorption techniques to the sunlight one side, as adopt vacuum insulation, black nickel coating heat absorption, change luminous energy into heat energy.Heat energy passes to and the contacted thermal absorption carrier of black nickel coating case again.According to heat energy application target difference, the thermal absorption carrier can be divided into several situations.1 kind is to make heat transfer medium with light water, as boiling water, cooks, heating, producing steam, can use water as heat transfer medium; 2 kinds of situations can select for use oils to do heat transfer medium if will wish to obtain in cooking, the baking etc. warm target, do the temperature that medium can obtain 300 ℃ as castor oil.3 kinds of situations if will wish to obtain higher serviceability temperature, can select for use the metal of low temperature fusing point or salt to do heat transfer medium, as KNO
3, NaNO
3Salt-mixture, the thermal barrier that contains the heat absorption salt can be transferred to other with heat place., can realize that with Thermo Isolation Technique quick heat release reaches people with slow heat release and uses hot purpose.(11) be the heat insulation sheath of luminous energy absorption plant, its effect is the hot transmission loss that as far as possible reduces the photo-thermal absorption plant.The present invention adopts foaming asbestos putty or glass fibre to make insulation material, and the insulation material outside is a protective metal shell, prevents insulation material fragmentation, contaminated environment.(13) be the heat transfer carrier conduit, different according to serviceability temperature with pressure, can select different materials for use, as: with plastic tube, rubber tube or metal tube etc.
(c). " thermal power transfer use part ": also be key component of the present invention.By figure number (14), (15), (16), (17) are formed.(16) be heat absorption mounting medium reservoir, also be the thermal power transfer container.For safety, the convenient application, code name (14) has been installed on thermal energy conversion device, the heat-storing device safety valve when container inner pressure transfinites, plays the safeguard protection effect.Device (15), the heat-storing device alarm, the signal that gives the alarm when temperature surpasses serviceability temperature correctly uses in order to people.(17) hydrothermal solution bleeder.When thermal barrier reaches serviceability temperature, open this valve and can take out hot liquid easily, as hot water or boiling water or high-temperature steam.About the reasons are as follows that thermal energy conversion device uses: condenser luminous energy absorption plant must be installed on the focus of condenser, and this focus constantly changes to give with the sunlight position uses heat energy to make troubles.As heat up water, cook, cooking direct direct control on the luminous energy absorption plant just.Must place a fixed position.By the heat transfer pipeline thermophore is introduced in the thermal energy conversion device.Thermal energy conversion device can have two kinds of conversion methods.A kind of is direct conversion, promptly directly uses from heat transfer pipeline defeated next hot water, boiling water, steam.A kind of indirect conversion of crying promptly enters in the coil pipe that is provided with the thermal energy conversion device from the defeated thermophore that comes of heat transfer pipeline, adds heat absorption carrier in the thermoconverter by coil pipe, solar energy equipment of the present invention as required, and two kinds of ways all can be used.
(d). " support section "
Part among Fig. 1 except that three parts of above narration all can be included into support section, comprises figure number (3), (4), (5), (6), (7), (8), (9), (10).As everyone knows, the feature of solar concentrator is only just can obtain high temperature heat at focus point, and the track of the sun is that the west falls by the east rise forever, condenser mirror has only vertical plane could obtain maximum photo-thermal to sunlight to accept efficient, so luminous energy absorption plant, must be placed on the focus of condenser, make itself and condenser mirror be in relatively-stationary position, and can rotate with the condenser mirror tracks sunlight.The measure that the present invention adopts is that the metal rod with hollow is welded into a kind of truss, shown in (3) among Fig. 1, with collector lens with place the luminous energy absorption plant of focus to link up, form a kind of fixed relationship, because of the collector lens diameter big, luminous energy absorption plant diameter is little, and this fixed relationship just forms a kind of sunlight focalizer of taper.This device rotates in tracks sunlight.Cone-channel condenser is by rod member code name (5) and broadwise turning axle code name (4) firm welding.(4) be installed on the U-shaped support, can rotate by 90 degree, thereby realize the tracking of sunlight broadwise.The U-shaped support is installed on again on the warp-wise turning axle (7), and the warp-wise turning axle links to each other with warp-wise swivel bearing assembly (10).Warp-wise swivel bearing assembly connects with fixed support (9) mutually by lead screw.Fixed support (9) can be put with ground in activity, also can be by foundation bolt and ground fixed in position, should adopt to fixedly install season at wind sand and be advisable, for guaranteeing that cone-channel condenser has a stable focus point, unlikelyly focus is rocked because of wind sand influence, the warp-wise turning axle should be tried one's best and be considered that toward adding length direction secondly warp-wise swivel bearing (7) can be provided with the major diameter steel ball thrust bearing through particular design.Compress with spring and nut between axle and the bearing and make its unlikely teeter.Simultaneously, because the variation of medium amount also will make cone-channel condenser broadwise out of trim or produce broadwise vibration effect focusing quality in the influence of wind sand and the thermal absorption device, measure of the present invention is that a cover brake gear is installed on broadwise turning axle and U-shaped support, with reference to (6) among the figure 2.The warp-wise rotation is followed the tracks of corresponding brake gear equally also is housed, and condenser is the time spent not, tight this device of can stopping.Loosen brake during use, but still keep certain braking force, it can not be rotated arbitrarily, but under the effect of tracking signal, direction rotation on request.
(e) " tracking section ":
Aforesaid broadwise rotation, warp-wise rotation and braking mechanism had both belonged to support section, had prepared condition for the sunshine tracking function of condenser again, and automatic tracking problem is mainly narrated in this part.The automatic following function of condenser of the present invention realizes adopting two kinds of methods.Method 1, tracking technique requirement for middle-size and small-size condenser, broadwise rotation 0～90 degree, warp-wise rotation 0～180 degree, this condenser also can promptly respectively be installed a thermal sensor at the edge, upper and lower, left and right of luminous energy absorption plant from motion tracking except that can manually following the tracks of, the motion of left and right thermal sensor control warp-wise, the motion of upper and lower thermal sensor control broadwise.In volatile liquid is housed, link by pipeline and the small-sized hydraulic piston of control broadwise rotation with the warp-wise rotation, the morning condenser is aimed at the sunlight that rises, rising with the sun, the focal spot of light is heated thermal sensor off-focal, and expansion evaporates, promote piston, make the condenser focal spot return the focal position again.So analogize, condenser will be followed to the sun always and be set.Be the control piston movement position, on the piston feed line, install non-return valve additional, with non-return piston retraction.For replenishing the hydraulic pressure oil mass, can on pipeline, install the additional lubricating cup of band retaining valve additional.Method 2 for the tracking technique requirement of large-scale condenser, beyond decapacitation is manually controlled, is more wanted and can accurately be controlled automatically, can adopt the singlechip technology of temperature-sensitive electric signal control.The Single-chip Controlling servo electrical machinery system is realized automatic control function.This technology is not included in the present invention, so do not describe in detail.
Fig. 8 is the linear focus solar concentrator synoptic diagram that utilizes curved surface solar panel of the present invention design, and the burnt condenser of big molded lines can be made and fixedly also can make tracking mode.Code name among Fig. 8 (1) is a linear focus solar panel, and (2) are absorption installation of heat energy, and (3) are the thermal cross over device.Because solar panel is a stationary installation, thermal energy conversion device (2) then must be made the function with energy tracks sunlight focus.
