Radiant energy collecting apparatus

The present invention relates to a kind of radiant energy collecting apparatus, particularly relate to solar energy collecting equipment in every respect, be convenient to this kind equipment aim at the device of the sun, under adverse weather condition this kind equipment of protection device and make the device of this kind equipment stable operation.

Utilize solar heating or generating, sunlight need be put together usually, so that improve the temperature of accumulation of energy and delivery of energy medium.

Various methods sunlight to have been put together.One of them method is to utilize the round mirror in parabola cross section, and the center line of mirror disk points to the sun.This parabolic mirror must be installed proper, makes it follow the circular motion that the sun moves all the time aloft.

In addition, because the drift angle of the sun changing from the Summer Solstice to Winter Solstice, thereby circle mirror its situation of circular arc when aiming at the sun and aloft moving also will and then change every day.Satisfy these and require just to need complicated mechanism.

In the said method, solar energy is to focus on the single very little focus, and suitable heat absorber is equipped with at the focus place, is difficult to solar energy is sent to the place of applied solar energy like this.

Also have another kind of system that the parallel reflective groove in some parabola cross sections is aimed at the sun.This system concentrates sunlight on the focal line of the direction that is parallel to the feeder aligning sun.This reflective groove is formed by a slice parabolic mirror or by a series of eyeglasses.From focusing on and the viewpoint of efficient, the important point is under two kinds of situations, single or multiple eyeglasses be supported, and makes their unlikely positions of departing from alignment configurations at each optical collector at parabolic wire casing focal line place.For this reason, need the accurately large scale structure of manufacturing usually.

The light harvesting groove can north and south orientation, and install to such an extent that make the stroke that self can follow sun operation on daytime.Meet this requirement and also need complicated mechanism.

Therefore, solar energy is collected in the pipe that suitable heat absorption liquid is housed usually, and pipe is installed on the focal line of parabola reflection groove.

In this light harvesting tank systems, each groove also can the thing orientation be installed, and so just need once a day each groove be aimed at the camber line of the sun, makes it can adapt to the variation of sun drift angle.Control this alignment procedures and also require complicated mechanism.

When the parabola reflection groove is installed, no matter be north and south orientation or thing orientation, each groove all need be adjusted to such an extent that make its focus all the time facing to the sun, and method is that each groove is installed on the axis that is parallel to reflective groove focal line rotationally, and this needs a plurality of rolling bearings and relevant mounting structure usually.

In addition, also the reflecting surface of solar energy collecting equipment need be disposed to such an extent that make them avoid the destruction that the foeign element such as hail may cause usually.This often just need adopt the safety glass of high-quality thereby high price to reach this purpose when making each speculum.In addition, for the purpose of protection, often each reflective surface need be deviated from the direction that hail attacks.

Figure 13 is raft and the lens systems partial plan together with the impeller assembly of Figure 12;

Figure 14 a-c be respectively one of them floating plate shown in Figure 10 end-view, fall planar view and side view.

Referring to accompanying drawing, and at first referring to Fig. 1 to 3.There is shown the solar energy collecting equipment 10 of the preferential form of recommending of the present invention, this equipment has a water receptacle or storage tank 11, this storage tank can for example comprise pond or dam or special container, the outer wall 12 of storage tank round with hold the water of dressing in container 11.Platform 13 is installed in the container 11 swims on the water of containing in container 14, water is in water level 15.Platform 13 can be made by the easily floating material such as foamed plastics, also can be installed on the thin layer that this class material makes.Not so platform 13 also can be made with the storage tank that sealing air is arranged, or outfit makes it floating with other device.

Ring 16 is fixed on the platform 13 or with platform 13 and forms an integral body, thereby centers on the total fluid-tight lateral margin of formation of external diameter of platform 13, and ring 16 extends in the bottom side of platform 13.

From Fig. 2 and 3, can see, be formed with groove 17 on the base 18 of container 11, usually continuously round container 11, thus the annular of formation.The external diameter of groove 17 is less than ring 16 diameter, thereby is formed with land face 19, encircles 16 when water is extracted and will rest on the land face 19 from container 11.

Internal diameter around chamber wall 12 is equipped with some deflector rolls 20, is pressed on the ring 16, thus the relative position of maintenance platform 13.One or more deflector roll 20 can be made it easy to drive platform 13 and be rotated by Motor Drive, thereby control solar energy collecting equipment 10 is to aim at the sun.

One or more outlet 21 couples together with suitable pump valve assembly 22, makes water can be under platform 13 be pumped into platform 13 tops or be pumped into the auxiliary tank (not shown) through pipeline 23 through footpath flow export 24.Water velocity and direction can be by 22 controls of pump valve assembly.The base 18 of container 11 also is equipped with groove 25, is communicated with pump valve assembly 22 through pipeline 26.

A plurality of sunlight concentrators 27 are supported on the platform 13 as shown in Figure 1 and row arrangement.Can be clear that from Figure 4 and 5 each concentrator is made up of series of parallel eyeglass 28, eyeglass 28 can be a curved surface, also can be the plane, and shape has a certain degree, thereby forms large-scale elongated parabolic mirror, brings into play the effect of this cylindrical mirror.These eyeglasses 28 dispose to such an extent that it is focused on sunlight on the top solar collector pipe 29 (for example clarinet), and collecting pipe 29 is contained on the leg-of-mutton suitable shelf 30 in eyeglass 28 tops.Each collecting pipe 29 suitably links together, and makes it collect heat energy by known mode, is applied with the known any way of the industry then, for example as the energy in the power station of Steam Turbine Driven.For this reason, collecting pipe 29 can be equipped with heat absorption or the energy-absorbing medium that resembles heat absorption oil and so on.The collecting pipe 29 of each concentrator 27 can for example link together by manifold, and the warmed-up medium that pipeline 29 is carried is then for the usefulness of producing steam.Not so the medium that also can make each collecting pipe carry circulates in closed-circuit system, and extracts heat energy with heat exchanger from medium.

Aim at the slight error that produces in the sun process for compensation condenser 28, above collecting pipe 29, settle an arc-shaped reflecting mirror 31, be made into to such an extent that make it play a not imaging concentrator.

Can stop the effect that the element that shines directly into the radiant energy beyond the condenser 28 is collected heat energy for improving from other of each element of shelf 30 and structure, have reflective or reflecting surface 32 (see figure 6)s on these elements, or making these surfaces form the part of these elements, surface 32 disposes to such an extent that make its focal line with eyeglass 28 become 90 degree basically.The radiant energy of the sun is reflexed on the eyeglass 28, again on eyeglass 28 condenser tube ferrules 29 or reflector 31, shown in each arrow among Fig. 6 from surface 32.

Platform 13 is preferably made by the pliable and tough easily floating material of thin foamed plastics that resembles light weight and so on.Like this, platform 13 because pliable and tough and comply with its unsteady place liquid flat surfaces thereby can keep flat state when floating.So each condenser 28 will keep correct focus state or focus state basically with respect to its relevant collecting pipe.Any athletic meeting that platform produces because of for example fluctuating makes collecting pipe 29 do corresponding motion, thereby collecting pipe 29 is kept or remains essentially on the focus of the eyeglass relevant with it 29.Platform 13 adopts the pliable and tough easily floating material of light weights to greatly reduce the cost of system, guarantees that simultaneously each eyeglass aims at its gatherer all the time.

Said above that rotate for making platform, wherein one or more deflector rolls 20 can be by Motor Drive.For this reason, one of them deflector roll 20 ' can be connected with driven roller 34 by

belt

33,34 of driven rollers are by servomotor or 35 drivings of other drive unit.The driving of servomotor 35 is for example adopted the tracking means of phototransistor or other light-sensitive element and projection means by tracking means 36 control of any known form, projection means according to the situation of self aiming at the sun at the next shade of light-sensitive element upslide.Certainly can also adopt other systems to come according to sun's motion with the motion of control platform 13 or impel platform 13 motions.

During use, when the sun comes up in the east, tracking means 36 can rotate by servomotor or other drive unit 35, drive pulley 34, belt 33 and deflector roll 20 ' drive transportation by driving platform 13, makes its longitudinal axis point to the vertical meridian of the sun on horizontal line thereby drive concentrator 27.Like this, the longitudinal axis of concentrator 27 is on the vertical plane that stops sunlight.The sun is from this head of its curved path when moving on to the other end, it is followed the tracks of at the vertical meridianal concentrator 27 of changing into of horizontal line, at this moment platform 13 swims on the liquid 14 in container 11, carrying

concentrator

27,27 of concentrators are driven by its drive system, thereby make its longitudinal axis aim at the sun all the time.Like this, during The sun came up, collecting device 10 is exposed to the greatest irradiation of the sun all the time and can descends, thereby makes the collection of solar energy reach optimum efficiency.Owing to adopted floating platform 13, thereby equipment 10 can move easily and easily, and makes concentrator 27 aim at the sun all the time.

If it seems that the risk of hail or similar destructive weather phenomenon are coming, at this moment just start pump 22, significantly water is pumped into cistern from water receptacle 11, platform 13 is descended.So lateral margin or encircle 16 bottom and contact with the base land face 19 of container 11 produces general sealing function.Then, the pressure under the whole platform slightly descends, and at this moment just impels water to flow out, and flows to the position of platform 13 tops by pipeline 24.Step-downs under the platform 13 should be kept to such an extent that make it be enough to prevent platform 13 emersions in pipeline 24 on the water surface in the pumping, thereby make water logging not have platform 13 and relevant concentrator 27, prevent that they are impaired.

Not so also can not rely on step-downs under the platform 13 to keep platform 13 to be in the water and adopt mechanical device to reach this purpose.For example, can make the steady pin that is installed on container 11 inwalls 12 or member after platform is under water, inwardly stretch out, make in the sunlight concentrator 27 immersion water and make the reflecting surface of concentrator 27 or eyeglass 28 be in shielded state.Platform 13 is emerged again, can extract steady pin or member out.Not so also can be equipped with one or more air chambers or storage tank, platform is sunk, just can make the platform come-up toward wherein filling air toward wherein pouring water to platform.

With water by water being sent back in the container 11 in pipeline 26 lead-ingrooves 25.In view of the flexibility to a certain degree of platform 13 tools, water is introduced in the groove 25 of centers under the platform 13 that the platform centre is slightly raised, thereby need be made concentrator 27 see that again the solar time guarantees draining fast and effectively.

The unsteady support system of platform when Fig. 7 and 8 shows platform 13 and is configured in such as lake, bay, river etc. immense waterborne.The same concentrator 27 that a plurality of and row arrangement are arranged of platform 13 and front only fully shows one of them concentrator among the figure.Platform 13 in the present embodiment is equipped with the lateral margin 37 of setting around its periphery, its upper limb to one unsteady member place or also can arrive the termination of a series of unsteady members 38 places.In an illustrated embodiment, member 38 and can be equipped with around the edge 37 foamed plastics that fully extend ringwise.Other unsteady members 39 can be connected with each parabola concentrator 27, are placed in the core that concentrator 27 covers usually.Member 39 preferably is contained on the rod member 40, is spaced a distance with each condenser 28.Member 39 preferably is made of the foamed plastics elongate articles, is being supported securely by rod member 40.Rod member 40 also can be made of short wire or other pliable and tough attachment.

Want to make platform 13 for example sinking as shown in Figure 8 under the harsh climate condition, as long as water pump is delivered on the table top surface with proper device (for example common pump).Be equipped with one or more the sort of water supply and sewage assemblies 41 as shown in Figure 8 perhaps also can for platform 13.Each assembly has one to pass platform 13 and extend to the hole 42 that the ring edge under the platform 43 aligns.Impeller 44 is connected with drive motor 45, is configured in the edge 43 and is immersed in the liquid in the edge 43, and 45 tops at platform 13 of drive motor are being supported by for example trestle 16 in any suitable manner.When motor 45 was pressed the first direction driving, water will be forced into platform 13 top sides by edge 43 and hole 42 under platform 13.When wanting to drain water on the platform 13, drives impeller 44 is rotated in the other direction, so water is just gone out by hole 42 pumpings.

Pump is kept on the platform by lateral margin 37 to the water on the platform 13, so platform 13 begins to sink.If each limit of platform 13 will sink earlier, the limit member 38 that then floats will support them.So water can continue to be pumped into concentrator 27 is immersed in the water, till reaching a stable dynamic balancing, at this moment the position of platform 13 between lateral margin 37 supported by unsteady member 39.After the water that edge 37 is preserved was drained, platform 13 just was raised on the water surface once more, thereby concentrator 27 is exposed in the sunlight.

Referring now to Fig. 9,, there is shown the plane of the another kind of form of the present invention, a kind of form that this is made up of a typical raft, a plurality of special-purpose speculum wherein and top solar collector system and their support all do not draw, and these elements have been shown among Figure 10.Be formed with a plurality of grooves or plate 53 with different angles in the buoyant raft 52 as we can see from the figure, also have a plurality of eyeglasses 54 on the buoyant raft 52.These eyeglasses 54 and groove closely-related with it focus on the solar collector pipe 56 its ray that can keep radiant energy (being generally sunlight) 55 by certain angle configurations.In addition, if the alignment case of eyeglass 64 has deviation slightly, sunlight 55 will shine on the radiation shield 57, shines on the solar collector pipe 56 again.

Solar collector pipe 56 and radiation shield 57 are installed on the

suitable shelf

58, and 58 on shelf directly is attached on the raft 52.Also can be attached to shelf 58 indirectly on the raft 58, for example shelf 58 is attached on the floating block 59, floating block 59 then directly is attached on the raft 52 itself.

During operate as normal, raft 52 can float in the storage tank, and relative water level is as numbering shown in 61.Certainly, storage tank can be the water of any suitable vastness, can be artificial pond, natural bay, river mouth or dam.

Should protect each eyeglass 54 to make it avoid may attacking of hail if weather condition shows, then take adequate measures water to be pumped into the top surface of buoyant raft 52 from storage tank.

The little wall that the external diameter of raft 52 (if not or circular configuration then be the outer rim of raft) is defined with the floating block 59 that is made of suitable easily floating medium (for example foamed polystyrene), a part that perhaps should little wall formation raft 52.Also be equiped with the vertical floating block 60 of other on its length direction of raft 52 upper edges, and be fixed on firmly on the raft 52.The lower surface of these floating blocks 60 (seeing the most clearly from Figure 14 a-c) has some otch or aperture 63 (also referring to Figure 11).

In addition, though it itself can be all-in-one-piece it should be understood that raft 52, the long raft structure of some parallel special uses is combined the large-scale raft 52 of formation also belong to scope of the present invention, this long raft structure can be fixed together by any suitable mode, shown in the numbering 64 among Figure 10 for example.

Being provided with

impeller

65 and 66 in the general position of raft 52 passes platform 52 and is fixed on this position, the aperture 70 of adjoining each topped arranged spaced, be installed on the driving shaft 67, driving shaft 67 then properly is attached on the raft 52 by for example carriage shown in the figure 69 itself (sees Figure 12 and 13).Its spiral corner of blade of last impeller 65 and following impeller 66 is preferably opposite each other, and its purpose is about to explanation after a while.

Aperture 70 is positioned on the pedestal of raft 52, make water can the beneath of raft 52 and above between directly the circulation.In most preferred embodiment shown in Figure 12, raft 52 itself is made by fully easily floating material, thereby can support entire equipment, and eyeglass 54 is surfaced.Therefore, that works as shown in the figure in aperture 70 opens wide.

On the other hand, if raft 52 needs extra buoyancy to make eyeglass 52 keep surfacing in normal work period, then can make raft 52 and resemble the ship that an outward flange is holding, the displacement of its volume is enough to make the unlikely edge top (like this, even eyeglass 54 is in and is lower than around the raft water surface of water level and also can not be buried by water) that rises to of the water around the raft.In this another kind of embodiment, each aperture is preferably closed in normal work period.This can realize by the valve that can suitably be controlled is set, open or close this valve so during operation on demand.

For water can be flowed by certain direction, also can be equipped with pipeline or cover cap 71 in addition, be installed in the middle part of impeller 65 and 66.Adjoin one or more impellers place and preferably be equipped with another pipe-line system 72, suitably installing makes it vertical current can be guided to impeller 66, and is transformed into the current of bottom horizontal flow sheet by this impeller, thereby controls the motion of raft 52.To control like this, the single pipe-line system 72 that can be controlled selectively can be set, perhaps also can be provided with the system of a plurality of impellers 66, each impeller is controlled by different modes, at this moment as long as the selected impeller of control can be controlled the motion of raft 52.

Certainly, be equipped with the scope that external driver device also belongs at least one aspect of the present invention for raft 52.For example, raft 52 is placed in a pond and can adjoins pool side reliably when settling, and can make it follow sun's motion, shown in the foregoing description of for example Fig. 2 and Fig. 3 with the motion that is located at the suitable driving device controls valve that pool side engages with raft.

The course of work of the above-mentioned most preferred embodiment of present device is as follows.

During operate as normal, when eyeglass 54 was exposed in the sunlight, the relative water level between the storage tank at raft 52 and its unsteady place was shown in inclined to one side number 61.As mentioned above, can suitably control the orientation of raft 52 according to the situation of the sun by means of pipeline 72.

If weather condition shows that eyeglass 54 may go to pot because of the factor as hail and so on, at this moment the water in the storage tank is pressed onto the surface of raft 52 by aperture 70 with regard to actuating motor 68.

At this moment water naturally and understandably can focus on each indivedual position, and raft 52 70 position is immersed in the water significantly in the aperture, and eyeglass 54 still is subjected to the prestige association of weather effect at other higher position simultaneously.Yet floating

block

59,60 is made cone wide at the top and narrow at the bottom, and this inverted cone-shaped structure makes the water that focuses on any indivedual positions be diffused into the whole surface of raft, thereby the degree of depth of guaranteeing the water that shields on all eyeglasses 54 is even.Like this, water is just protected all eyeglasses 54 reliably with the water level shown in numbering 62 among Figure 10.In fact, the pyramidal structure of floating

block

59,60 has been guaranteed water the degree of depth has been consistently, evenly in its whole overbank process.(in addition, the aperture 63 of

incision floating block

59,60 bottoms does not have the process of whole raft to play a driving role to water logging yet, and promptly aperture 63 can be pumped on the raft 52 water, and it is circulated in whole raft 52).

But it should be understood that floating

block

59,60 also can not be made into continuous cone or only make it tapered on one side and make step, makes it that desired stagewise buoyancy is provided.But in this structure, the horizontal sectional area of floating block is preferably in apart from raft 52 any specified distance and must be equal to each other.

Be in the whole process of risk at eyeglass 54, motor 68 should keep with suitable rotation speed operation, and the water that top impeller 65 can be made shield floods the whole eyeglass 54 of lid all the time.

Eyeglass 54 is tided over after the risk, motor 68 can be cut off.Raft 52 is subjected to the natural buoyancy function of water, thereby water can oppositely flow by aperture 70 when cutting off impeller 65, thereby raft 52 itself is emerged at last again, and eyeglass 54 comes out, thereby can be with solar energy reflection in collecting pipe 56.In addition; in most preferred embodiment; why on raft 52, enclose (as numbering shown in 64) particular normally in order to make water also can spill (but obviously this class is sewed and should fully be made it as far as possible little, makes impeller 65 make water remain on desired water level 62) during the weather that eyeglass 54 needs protection by these parts.Certainly, it should be understood that effect that floating

block

59,60 keeps whole raft surface water level to preventing that ponding on the raft 52 from being further facilitation, thereby the operating efficiency that has hindered equipment.

Certainly,, can make motor 68 counter-rotatings, make impeller 65 force water to pass through aperture 70 toward dirty for adding the piece floating-upward process.Above-mentioned another embodiment of the present invention (being about to the embodiment that raft is configured to the canoe form) also can adopt this mode of operation, and at this moment impeller 65 plays the ponding blowdown pump, and water is got rid of from raft.

During impeller 65 work, water up fails to be convened for lack of a quorum by aperture 70 and makes raft local under water at the position of adjoining aperture 70 and impeller 65.Yet another impeller 66 helical angles of rotating on same driving shaft 67 are opposite, produce equilibrant force upwards, hinder the carrying out of this operation.Suitably select the relative spiral angle and the blade area of

relevant impeller

65,66, although, can keep raft 52 and make it remain level existing because of water pump being delivered to the power that produces on the raft during the bad weather.

Certainly, if after bad weather, from the process that raft 52 dewaters, want to make

impeller

65,66 counter-rotatings, then two

impeller

65,66 vertical forces that produced are reverse, so at this moment the impeller 66 of bottom produces and prevents the equilibrant force (this configuration mode tends to make the water on the raft 52 to focus on the low-lying position of departing from aperture 70, and this is that we are undesirable) that raft 52 rises in the position in aperture 70.

Certainly, because the effect of

coaxial impeller

65,66 is opposite, thereby additional pipeline 71 can rotate the opposite liquid flow point of direction that be produced with them when preferably working and opens.

Therefore it is not too high and can improve the solar energy collecting equipment of the efficient of collecting solar energy to greatest extent to the invention provides a kind of cost.This equipment can be made with material cheap and that be easy to obtain, and can make main equipment to cooperate the purpose of industrial generation.Equipment of the present invention also goes for single family.Although the sunlight concentrator of introducing so far generally all is to be horizontal basically, they and horizontal line are tilted, but when using still perpendicular to the vertical plane that stops sunlight.

In addition, though it should be understood that the suitable especially solar thermal energy of collecting of equipment of the present invention, it also can collect the radiant energy that other form can add collection.

Support platform preferably is contained in the storage tank its liquid that can float, but this liquid can comprise any other big quantity of fluid, for example river, seawater or be contained in water in other tank.

Therefore, although top explanation is to illustrate what the mode of the embodiment of the invention was carried out by way of example, but those skilled in the art that scholar knows, the modifications and changes that the foregoing description is done all should be considered as belonging to the broad range of this specification appended claims.
