Description

Speculum

Technical field

The application relates to technical field of solar utilization technique, particularly a kind of solar energy reflection mirror.

Background technology

China is that energy-consuming big country is atmosphere pollution big country simultaneously, has been very urgent major issue so greatly develop green energy resource such as solar energy, but since at present the solar facilities cost higher, cause the solar energy utilization to popularize slowly.As the glass that uses the valency of holding concurrently substitute metal such as stainless steel as the solar energy reflection mirror, will greatly reduce the cost of solar facilities, but because the solar energy reflection mirror generally is installed in the field that does not block, sometimes be installed in densely populated residential building roof, simple glass is corrosion-resistant but frangible, when running into destructive wind-force, when particularly running into violent typhoon, carrying sand etc. in the high wind secretly, making the glass reflector fragmentation easily, even hurt sb.'s feelings; Even so must make glass reinforced or the glass fragmentation, its fragment still sticks on the interlayer of speculum, reduce injury to the people.Teacher's application numbers such as Zhang Yaoming are that 200510039114.8 Chinese patent discloses a kind of heliostat device, propose to use double-deck simple glass therebetween PVB glued membrane as heliostat, its design is fine, but with simple glass as the mechanical strength of former common laminated glass and resistance to heat shocks not as strengthening laminated glass.

Summary of the invention

It is the safety durable speculum of double valency again that the technical problem that the application will solve provides a kind of; And the effective reflecting surface of spread reflection mirror as far as possible; And thereby safety glass framework when strengthening laminated glass connects eyeglass by the damping seal and protects reflecting layer and adhesive in the interlayer.

For solving the problems of the technologies described above, the described speculum of the application is by framework, reflecting layer, and framework connects the safety glass eyeglass and forms.Said safety glass eyeglass is to plate the reflecting layer or paste the glassware that reflects paster in the surface on the sunny side in safety glass the surface of safety glass sunny slope or interlayer, hereinafter to be referred as eyeglass, it mainly acts on is to flash back the sunlight, and safety glass mainly to act on be the support fixation reflecting layer; Said framework is to play the parts that are connected and fixed the eyeglass effect, and framework is by fixedly connected or flexible connection fixing len.Be and solve that above-mentioned to provide a kind of be that hold concurrently the again technical problem, the technical scheme that is adopted of speculum of valency of safety durable is: the original sheet glass of the valency of will holding concurrently is processed into the safety glass of safety durable, plating or be stained with the reflecting layer again becomes the safety glass eyeglass, is connected into the safety glass speculum by framework.It mainly acts on: the sunlight reflected of incidence reflection mirror to extinction body, is transformed into heat energy or electric energy by extinction body with luminous energy; Be the incidence reflection mirror sunlight by the reflecting layer on the safety glass or by the reflective layer reflects on safety glass and the framework to extinction body.The safety glass speculum can be a kind of solar energy reflection mirror by sheet materials such as the alternative stainless steels of safety glass, to be the utilization reflection law with the sunray of parallel incident be reflected into said solar energy reflection mirror focuses on or reflection ray, the light of parallel or optically focused reflexes to extinction body and makes its absorption be converted into other energy, the speculum that solar energy is utilized; Can be speculums such as solar cooker, flute profile parabolic mirror, dish-shaped parabolic reflector, hemisphere face speculum, flat reflective mirror, compound parabolic mirror, composite mirrors, linear Fresnel.

Said framework can be fonts such as mouth, day, order, field, also can be in-line, ㄈ shape, can also be netted, promptly speculum can be made up of an eyeglass, also can be made up of the polylith eyeglass; Framework can be square, also can be circle etc.; Framework can be made the plane, also can make curved surface with speculum, promptly can make the framework of various solar energy reflection mirrors.Framework can be fixedlyed connected, also can flexibly connect with eyeglass; Said fixedly connected be meant two or more objects by with screw, bolt, welding, riveted joint, snapping, bonding etc. make the motionless connection of relative fixed between them; Fixedly connected can be to have groove on the framework cross section, elastic shock attenuation seal or elastomeric damper member such as rubber strip is housed in the groove, is connected and fixed eyeglass by damping seal or shock absorber part; Shock absorber part only plays cushioning effect, and the damping seal uses during for laminated glass at eyeglass, it can make moisture and oxygen not enter in the interlayer, thus reflecting layer and adhesive in the protection interlayer, and promptly the damping seal plays sealing and cushioning effect; Also can be with screw, bolt, welding, riveted joint etc. stop bit spares such as compressing tablet, briquetting, clip to be fixed on the framework, stop bit spare be fixed on eyeglass by damping seal or shock absorber part the surface or the opaco on the sunny side of framework; As framework is that hardness such as plastics, plastic cement are not very high materials, then above two kinds of connections can be without damping seal or shock absorber part, be that framework directly connects eyeglass, certainly because the thermal coefficient of expansion of framework and eyeglass is different, this directly the activity of being connected to be connected; Can also be with sticks such as adhesive sticker eyeglass is sticked in the groove in framework cross section on the seam or stick on framework surface on the sunny side or opaco, reinforce in case eyeglass comes off and hurts sb.'s feelings with stop bit spare again, different owing to the thermal coefficient of expansion of framework and eyeglass, require stick that certain elasticity should be arranged.Flexible connection connects eyeglass for framework by exhauster, and said exhauster can be to decide power exhauster or damping exhauster; Decide the power exhauster and be a kind of framework by unload the wind device connect eyeglass or framework by unload the wind device, connector connects eyeglass, makes eyeglass decide power and opens, slowly closes the device that puts in place, it is characterized in that framework is by unloading wind device connection eyeglass; The damping exhauster is that a kind of framework connects eyeglass by damper or framework connects eyeglass by damper, connector, makes eyeglass decide power and opens, slowly closes the device that puts in place; It is characterized in that framework connects eyeglass by damper; The difference of two kinds of devices be unload the wind device unload that the wind function is better than damper unload the wind function.Can be that the part eyeglass rotates with respect to framework in exhauster, promptly a part of eyeglass be connected with frame fixation, a part of eyeglass and framework flexibly connect, and promptly rotates with respect to framework.Details such as the principle of exhauster can be applied for reference to me, application number is: 200710027364.9 Chinese patent.Eyeglass can be direct or indirect with being connected of other parts, directly is after holing on eyeglass, connects other parts with securing member; Being that eyeglass connects other parts by middleware indirectly, can be that eyeglass is fixed with picture frame or fixed with picture frame by damping seal or shock absorber part, and its middleware---picture frame is connected with other parts again.

Said speculum sunny slope is whole all to have the reflecting layer for reflecting surface is meant the eyeglass and the framework of composition speculum sunny slope, or stop bit spare such as the contained compressing tablet of the contained picture frame of eyeglass and eyeglass and framework and framework and stay bolt spare all have the reflecting layer.Said framework can be connected or stay bolt spare connects by support member, from framework opaco connecting frame be called support member, from the stay bolt spare that is called of framework sunny slope connecting frame, support member connects ground by support or pedestal, stay bolt spare connects ground by support.Since stay bolt spare usually and frame fixation connect as one, so stay bolt spare, framework can be referred to as framework; Stay bolt spare can be tabular, also can be strip, it is fixed on the symmetrical two ends of speculum, and in fixed and uniaxiality tracking formula speculum, tabular stay bolt spare sun face is greater than strip stay bolt spare, therefore the application advocates to adopt strip stay bolt spare, to reduce sun face and wind surface.The cross section of framework can be square, I-shaped etc., so that it has broad and smooth surface on the sunny side, the reflecting layer can be plated or be stained with in its surface that faces south.Framework face south normal to a surface must with the normal keeping parallelism of its eyeglass that is connected and fixed because sunray is parallel incident ray, also must be parallel as both normal parallels, its reflected ray, thereby enlarged the effective reflecting surface of speculum.In like manner: stop bit spares such as picture frame or compressing tablet also should have broad and smooth surface on the sunny side, its normal should with the normal parallel of eyeglass, the reflecting layer can be plated or be stained with in its surface that faces south.Fixed in this way or uniaxiality tracking formula speculum also can be at the mirror surface of stay bolt spare, be that stay bolt spare connects on that side of speculum plating or is stained with the reflecting layer, and this side should be smooth; Because fixed or uniaxiality tracking formula speculum, always its incidence angle is not equal to zero for some time, the stay bolt spare one that be fixed on the speculum both sides this moment will be subjected to solar radiation, another shading, therefore the reflecting layer on the one stay bolt spare reflexes to incident ray on the eyeglass, light is reflexed on the photoreceptor by eyeglass again, thereby has enlarged the effective reflecting surface of speculum.The light that the above method is reflected in single speculum is few, but as be applied in the large-engineering such as solar electrical energy generation, that the effective reflecting surface of speculum is enlarged is many, the effective reflecting surface of the said mirror of spread reflection is as far as possible promptly realized by above method in the present techniques problem.

Said safety glass is meant through intensive treatment or compound with other material, has higher mechanical strength and resistance to heat shocks energy, and the glassware of security; Can be tempered glass or laminated glass or wire glass.Said safety glass eyeglass is by tempered glass or strengthens laminated glass or wire glass plating or be stained with the reflecting layer and form.Its characteristics are that mechanical strength is higher, are not easy fragmentation, even the glass fragmentation also becomes blunt fractionlet or the fragment of circle still to stick on diaphragm or the woven wire unlikely hurting sb.'s feelings.Said tempered glass claims safety glass again: through intensive treatment, have favorable mechanical performance and resistance to heat shocks can the general designation of glassware.Even its characteristics are the glass fragmentation, also become the blunt fractionlet of circle, unlikely hurting sb.'s feelings; Its technology has been lacked bonding process than strengthening laminated glass, and is simple relatively, but after also having lacked the glass fragmentation, the blunt fractionlet of circle still sticks to the function on the diaphragm.Glass reinforced processing mode has physical strengthening and chemical enhanced; Physical strengthening: comprise that wind quenching, oil hardening and fused salt quench; Quench as wind: glass when control is heated near softening point, shifts out in stove rapidly in heating furnace, makes with the high speed quenching face of drying; Because safety glass is a prior art, does not describe in detail so its technology is not done.Chemical enhanced: surface ion exchange, surface crystallization, acid treatment, coating, sulfur bloomization and thermal neutron irradiation etc.; With physical strengthening glassy phase ratio, has higher bending strength, anti-mechanical impact strength and heat-resisting shake intensity; Because compressive stress layer that its surface produces is thin and little with the internal stress of compression balance, even thereby outside slight crack reach inner, the also unlikely glass that causes is broken comprehensively.Said laminated glass has the laminated glass of reinforcement and common laminated glass, said reinforcement laminated glass is opaque or transparent plastic film or the lucite of embedding folder between two or the multi-disc tempered glass, is bonded into composite glass product flat or bending through heating, pressurization etc.; Promptly strengthening laminated glass is that former and common laminated glass are to be former laminated glass with simple glass with tempered glass; Transparent plastic diaphragm commonly used is a polyvinyl butyral resin; Because the mechanical strength of common laminated glass and resistance to heat shocks and security are not as strengthening laminated glass, so the application does not use common laminated glass.The shock resistance mechanical strength of reinforcement laminated glass exceeds several times than the simple glass of same thickness; Its characteristics are that mechanical strength is higher, are not easy fragmentation, even the glass fragmentation also becomes the blunt fractionlet of circle still to stick on the diaphragm unlikely hurting sb.'s feelings; Acquiring a certain degree, can make reinforcement interlayer bulletproof glass as its thickness, is the highest kind of intensity in the safety glass, so on densely populated residential building, should use and strengthen laminated glass as the speculum eyeglass.Said wire glass is the glassware that inside is embedded with wire or net.Be characterized in: when glass breakage, fragment still is bonded on the woven wire, unlikely hurting sb.'s feelings; The strength and stiffness of its interlayer wire or net are than diaphragm height.Wire glass is generally used the continuous calendering manufactured: when glass metal is flowed through in the middle of two pressure rollers of calender, above glass or below send into continuously through pretreated wire or net, make its drawing direction, and embed in the glass plate abreast along with glass.Because safety glass can not carry out processing such as machine cuts, boring, so just carry out intensive treatment after needing the eyeglass of processing to need boring earlier, cutting etc. to process.Eyeglass be bend glass, generally be with after the plate glass thermoplastic, with heavy bending method of groove or die pressing processing,, can attack from both sides into goods such as bend in one direction, compound bending and spherical curve according to the curved surface requirement.The quenching strengthening bend glass generally is to quench after the bending machining, with energy savings in this way at once; The interlayer bend glass can be with two of monoblocks or multi-disc glass bending machining together, and strengthening the interlayer bend glass can be that two of monoblocks or multi-disc glass are carried out intensive treatment respectively after the bending machining together, to guarantee the unanimity of each sheet glass curvature.

Said reflecting layer has been the metal level of light reflex; Can be with technologies such as sputter, coating, evaporations, with the coating of metal-plated such as aluminium, silver on safety glass or framework, also can be that sheet metals such as aluminium, silver are bonded at the safety glass paster on surface on the sunny side; Its effect is to flash back the sunlight; Reflecting layer plating or be bonded at safety glass surface on the sunny side can be operation plating in the end or be stained with the reflecting layer, promptly just plates or be stained with metallic reflective coating after operations such as bending, interlayer are finished, and is not subjected to scratch to guarantee the reflecting layer in process; As in interlayer, plating the reflecting layer, can be that to be plated in sunny slope first sheet glass be the bottom of surface glass, the i.e. opaco of first sheet glass, to shorten the stroke of light in glass, reduce energy loss, should select the low glass of iron-holder for use for its first; Just can carry out the interlayer operation behind the plated film.The reflecting layer is plated in the interlayer can protect plated film, prolongs the life-span of plated film, but sunlight sees through glass and causes energy loss; Be plated in lens surface, the reflectivity height does not have the loss of light transmission glass, but is difficult for the protection plated film, and the life-span is short; The characteristics of paster are can change after the impaired or oxidation in reflecting layer.Eyeglass can be made: speculum eyeglasses such as solar cooker, flute profile parabolic mirror, dish-shaped parabolic reflector, hemisphere face speculum, flat reflective mirror, compound parabolic mirror, composite mirrors, linear Fresnel.Because that glass is water-fast is corrosion-resistant, do not resemble non-ferrous metal and the easy oxidation of steel plate, not resemble fiberglass and plastic products aging easily, and the safety glass speculum has higher mechanical strength and resistance to heat shocks, is not easy fragmentation, so long service life; Because the safety glass eyeglass is not easy fragmentation, even broken, also become blunt fractionlet or the fragment of circle still to stick on diaphragm or the woven wire, so unlikely hurting sb.'s feelings is safe in utilization; Because the crooked and quenching of glass can use solar energy to heat fully, details can be applied for reference to me, application number is: 200610035987.6 Chinese patent, therefore can reduce the cost of safety glass speculum, because the raw material of glass is easy to get, so be one of sheet material of the most double valency in the market, as use solar energy to melt manufacturing glass, the glass price will further drop, this shows that the safety glass speculum is is hold concurrently the again speculum of valency of safety durable, promptly solved the application's problem of valency of should safety durable holding concurrently again.Therefore safety glass can substitute sheet materials such as stainless steel, can greatly reduce the cost of solar energy reflection mirror, reduces the consumption of metal, is beneficial to universal that solar energy utilizes.

The specific embodiment

Below in conjunction with embodiment the application is described further.

To be framework connect the safety glass eyeglass and form and have the two-way embodiment that unloads wind function speculum by unloading the wind device present embodiment.Fig. 1 is a tower type solar boiler heliostat scheme of installation.Fig. 2 is a heliostat installation side view.Heliostat is the flat reflective mirror, the tower type solar boiler is by flat reflective mirror 8, boiler and biography, storage, form with hot equipment, following flat reflective mirror 8 is called for short speculums 8, and it is reflexed to solar radiation on the boiler, absorbed and be converted into heat energy by boiler by a plurality of speculums 8 of different azimuth and different angle.The rotating shaft 7 that each fixedly connected multi-cavity bidirectional blade of the symmetrical two ends of speculum 8 unloads wind device 6, the multi-cavity bidirectional blade unloads wind device 6 to be called for short in the present embodiment and to unload wind device 6, two are unloaded the two ends that wind device 6 is welded in framework 9 respectively, two rotating shaft 7 same axis that unload wind device 6; The opaco center of framework 9 connects column 1 by spherical bearing 3, east-west direction and North and South direction are respectively installed a tracking means---and screw rod ratchet row 2 are on column 1, screw rod 4 terminations of screw rod ratchet row 2 are hingedly mounted on the slide block in the sliding tray 5, slide block can slide in sliding tray 5, and two sliding trays 5 are fixedly connected on respectively on the opaco of speculum 8 and framework 9; Stretching motion up and down by screw rod 4 makes speculum 8 around the swing of spherical bearing 3 centers, realizes that thus speculum 8 four corners of the world four directions precisely follow the tracks of the sun; Details such as its following principle can be applied for reference to me, application number is: 200620167990.9 Chinese patent.Framework 9 manufactures the framework that hollow has inner chamber for ㄈ shape by square steel, and promptly framework 9 is the different shell container of sealing simultaneously; Framework 9 connects speculums 8 and forms and decide the power exhauster by unloading wind device 6.

Fig. 3 is safety glass lens structure figure.Speculum 8 fixedly is made of by damping seal 12 usefulness picture frames 11 all around the safety glass eyeglass; Picture frame 11 compacting grooving shapes are strengthened its rigidity, play the support fixation eyeglass and enlarge the effect of contact-making surface, have avoided being connected hard firmly of eyeglass and rotating shaft 7 by damping seal 12 simultaneously; The sunny slope of picture frame 11 is pasted reflecting layer 10, makes speculum 8 sunny slopes whole for reflecting surface, plays the effect of spread reflection mirror 8 effective reflecting surfaces; Damping seal 12 can not enter in the interlayer moisture and oxygen, thereby reflecting layer 10 and adhesive in the protection interlayer play sealing and cushioning effect.The safety glass eyeglass by sunny slope tempered glass sheet, be called for short surface glass 13 and be plated in the reflecting layer 10 of surface glass 13 bottoms and plastic film 14, and opaco tempered glass sheet, be called for short end glass 15 and be bonded through heating, pressurization etc.; The safety glass eyeglass is hereinafter to be referred as eyeglass, and reflecting layer 10 is plated in the bottom of surface glass 13, with the protection plated film, prolongs the life-span of plated film, and the effect in reflecting layer 10 is that sunlight reflected with incident is to boiler; Surface glass 13 is selected the low glass of iron-holder for use, to reduce the absorption of glass to sunlight, the main effect of surface glass 13 and end glass 15 is support fixation and protection reflecting layer 10, they be through intensive treatment, have favorable mechanical performance and resistance to heat shocks can tempered glass, its characteristics are that glass is not easy fragmentation, even broken, also become the blunt fractionlet of circle, unlikely hurting sb.'s feelings promptly has security function; Its fractionlet still sticked to the effect on the plastic film 14 after plastic film 14 played bonding original sheet glass and makes the glass fragmentation, and promptly plastic film 14 is bonded into reinforcement laminated glass with surface glass 13 and end glass 15; All belong to prior art owing to strengthen laminated glass and reflecting layer, so do not describe in detail.

Because destructive power all reached maximum when wind was blown by speculum 8 normal both forward and reverse directions, just can make speculum exempt from destruction so must adopt two-way rotation to unload wind.Running into destructive wind-force when speculum 8 sunny slopes blow, because speculum 8 is that rotating shaft 7 axis are asymmetric installation, promptly wind area is big on one side, another side is little with respect to rotation, learn it is that the big left side of wind area, the right wind area is little by Fig. 2, produce a moment of torsion that turns clockwise thus; When torsion greatly to can overcome the pretension internal force that unloads wind device 6 time, rotating shaft 7 drives speculums 8 rotations diminishes the wind area perpendicular to wind direction, even speculum 8 suffered wind-force reduce, thereby avoids high wind destruction speculum 8; When wind-force is after external force reduces, rotating shaft 7 drives speculums 8 and slowly or first quick and back slow is rotated counterclockwise and sets back.When wind-force blew from speculum 8 opacos, its principle was identical, direction of rotation is opposite, so do not repeat.The details such as principle of unloading wind device 6 can be applied for reference to me, application number is: 200710027364.9 Chinese patent.

Since original sheet glass through intensive treatment, and use the damping of damping seal, so eyeglass is not easy fragmentation; Because that glass is water-fast is corrosion-resistant, be difficult for oxidation, be difficult for agingly, present embodiment uses the damping seal that moisture and oxygen can not be entered in the interlayer simultaneously, and in the reflecting layer plating interlayer, makes plated film do not drawn together wound, so the long service life of eyeglass; Because eyeglass is not easy fragmentation, even broken, also become the blunt fractionlet of circle still to stick to plastic film, so unlikely hurting sb.'s feelings is safe in utilization; Glass is one of sheet material of the most double valency in the market, this shows the speculum 8 valency safety durable again of promptly holding concurrently.And its sunny slope integral body is reflecting surface, has enlarged effective reflecting surface.
