Specific embodiment mode: embodiment 1:

Optically focused partly is core content of the present utility model.Form by (1) (2), be fixed on the sphere shape metal framework (2) by designing requirement, form a huge sphere shape Fresnel spotlight with the sphere shape curved surface solar panel (1) of transparent plastic mold pressing or injection mo(u)lding.So arrange by processing, production, assembling, convenient transportation decision.Because a concentrator must have enough energy if make the domestic consumer satisfied, energy shortage, design is exquisite again, also will be eliminated by the user, and general home-use energy thermal power is at least between 2～10 kilowatts.The solar ray energy metric density of earth surface is low, measures according to the parties concerned, and every square metre thermal power has between 400～700 watts.Now with mean value calculation, the sunlight of 2～10kw thermal power connects light area.At least should be at 3.6～18m ²Between, diameter must be at the area of a circle of 2～5m.Like this big surface area, to the requirement not only harshness but also difficulty of plastic processing mould, expensive, transportation inconvenience is installed difficult.The way that solves is to resolve into several portions with connecing the photosphere face, connects the light area size according to designed concentrator, can be divided into different piece, for the concentrator of Φ 4m～Φ 5m diameter, processes by mode illustrated in Figure 2.Spherical caustic surface is divided into 25 parts, and the centre is the circular solar panel of a reduced size.(even so diminish, also getting large size plastic jetting-moulding device could produce).

With reference to the A among the figure 2, the trapezoidal curved surface solar panel of the sphere B at 12 homalographics of the outer rim of A splicing constitutes a ring-type sphere, splices the trapezoidal curved surface solar panel of the sphere C of 12 homalographics again in the outer rim of B, constitutes another ring-type sphere.A, B, C, three kinds of curved surface solar panels are spliced into a complete spherical crown surface shape collector lens, with reference to the accompanying drawings 3,4,5, accompanying drawing 4 is represented the A template, accompanying drawing 5 is represented the Type B plate, and accompanying drawing 6 is represented the C template, and accompanying drawing 3,4,5 all makes a farfetched comparison Fig. 2 and amplifies 1 times, be clear display, it is all exaggerative significantly than actual prism that each organizes prism.Its solar panel gross thickness has only 5～10 millimeters sizes on the lens sizes of Φ 4m～φ 5m.All 25 curved surface solar panels all are fixed on the sphere shape metal framework (2) in an orderly manner.Reference diagram is attached 6, and metal framework is bent, is welded by steel, aluminium, the plastic-steel material of rectangle.Do 3 circles earlier by size, make 24 circular-arc quarter butts again, weld by the figure connection, metal framework must be processed by designing requirement, meticulous prefabricated each member, especially spherical outside surface does not allow the out-of-size scope, each prefabricated curved surface solar panel edge will just in time be buckled on the framework, cements each solar panel with viscose glue earlier, thereafter at the punching of rectangular tube intersection of welding, threading, fix each piece solar panel with screw, constitute a complete huge spherical crown surface Fresnel collector lens thus with protruding pad.

Fig. 2 is a desirable spherical crown surface shape Fresnel collector lens, and lens are made by certain thickness plastic plate mold pressing or injection moulding.Its cylindrical is the spherical crown surface of a high accuracy, best bright finish, inner lens surfaces is the ladder plane of a series of concentric annular, each ladder plane is all parallel with the baseplane, each ladder height is the same, each outer rim present position, ladder plane requires to equate with centre of sphere distance, promptly require the outer rim on ladder plane equal, to guarantee being linked with enough mechanical strengths between solar panel prism and the prism to the distance (thickness) of lens spherical outside surface." cylinder " that each concentric ring plane and lens spherical outside surface and ladder height form will constitute the prism of a series of concentric annular, and the end of a prism is the head end of another prism, so extend, and be long-pending up to reaching the desired optical cross section of people.All light of each prism will all be refracted on the singular point that is called focus.It is worth noting to have the highest luminous energy refractive index for guaranteeing lens, the bottom surface of each annular prism height direction is not " cylinder " on the ordinary meaning, but a frustum cone side, its elongated surfaces constitutes a conical surface, and the summit just makes it on focus.Its cone angle of prism far away of healing from the lens centre is bigger, and the prism angle is also bigger, can illustrate with graphing method easily.

About the difference of concentrator prism of the present invention and traditional Fresnel prism with reference to the accompanying drawings 7.

Figure first among Fig. 7 is traditional Fresnel lens, and O is the lens centre axle, and by finding out among the figure, prism decentre axle is far away, and its cone angle to focus is bigger, obviously r ₂＞r ₁, the prism angle theta ₂＞θ ₁, require the bottom surface of each prism and focus to constitute a conical surface, in Fig. 7, the half-angle of this cone angle is represented at the α angle in the figure second.The mn plate is a public substrate of fixing all prisms, otherwise prism can't be determined its position, and this is injection molded into an integral body by designing requirement with it when mold pressing or injection moulding.Single prism rings is end to end successively will to form a curved surface solar panel.

Figure second among Fig. 7 is modified Fresnel spotlight schematic diagram of the present invention, similarly r ₂＞r ₁, θ ₂＞θ ₁On behalf of the prism bottom surface, α the angle prolong the half-angle of the cone angle that forms when overfocus, different is that solar panel outer surface of the present invention is a sphere shape, and all light by prism all focus on the singular point that is called focus, its focus be that other Fei Shi concentrator is impayable for a short time.As the figure first is a focused spot.These characteristics mean that focus of the present invention can obtain more much higher temperature, more wide purposes will be arranged, as Metal Cutting, welding, fusing, destructive distillation, purification, photochemical reaction or the like.

The sunlight heat absorption partly is an important component part of the present invention.Form by (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 concentrator, 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 heat absorption carrier of black nickel coating case again.According to heat energy application target difference, the heat 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, and as the salt-mixture of KNO3, NaNO3, the heat carrier that contains the heat absorption salt can be transferred to other and locate with heat.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 hose or the like.

It also is key component of the present invention that thermal power transfer is used part.Form by (14), (15), (16), (17).(16) be heat absorption mounting medium holder, also be the thermal power transfer container.Be safety, convenience, (14) have 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 heat carrier reaches serviceability temperature, is opened this valve and can be taken 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: concentrator luminous energy absorption plant must be installed on the focus of concentrator, 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, the utility model solar energy equipment as required, and two kinds of ways all can be used.

Part among Fig. 1 except that three parts of above narration all can be included into support section, comprises (3), (4), (5), (6), (7), (8), (9), (10).The feature of well-known 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 concentrator, making the feature of itself and condenser device 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 concentrator, make itself and condenser mirror be in relatively-stationary position, and can rotate with the condenser mirror tracks sunlight.The measure that the utility model 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 focusing arrangement of taper.This device rotates in tracks sunlight.Cone-channel condenser is by rod member (5) and broadwise rotating shaft (4) firm welding.(4) be installed on the U-shaped support, 90 degree rotations, thus realize the tracking of sunlight broadwise.The U-shaped support is installed on again on the warp-wise rotating shaft (7), and the warp-wise rotating shaft 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 movable be swung with ground, also can be by fang 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 rotating shaft 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 disequilibrium or produce broadwise vibration effect focusing quality in the influence of wind sand and the heat absorption device, measure of the present invention is that a cover brake gear is installed on broadwise rotating shaft and U-shaped support, with reference to (6) among the figure 2, concentrator is the time spent not, tight this device of can stopping.Loosen brake during use, but still keep certain brake weight, it can not be rotated arbitrarily, but under the effect of tracking signal, direction rotation on request.

Embodiment 5 (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 concentrator again, and automatic tracking problem is mainly narrated in this part.The automatic following function of the utility model concentrator realizes adopting two kinds of methods.Method 1, tracking technique requirement for middle-size and small-size concentrator, broadwise rotation 0～90 degree, warp-wise rotation 0～180 degree, this concentrator also can promptly respectively be installed a heat 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 heat sensor control warp-wise, the motion of upper and lower heat 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 concentrator is aimed at the sunlight that rises, rising with the sun, the focal spot of light is heated heat sensor off-focal, and expansion evaporates, promote piston, make the concentrator focal spot return the focal position again.So analogize, concentrator 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 check valve additional.Method 2 for the tracking technique requirement of large-scale concentrator, beyond decapacitation is manually controlled, is more wanted and can accurately be controlled automatically, can adopt the singlechip technology of temperature-sensitive signal of telecommunication control.The Single-chip Controlling servo electrical machinery system is realized control function automatically.This technology is not included in the present invention, so do not describe in detail.
