Utility model content

The purpose of this utility model is to provide a kind of distribution mode of light-concentrating solar heat-collection device, and it has the efficient sun The advantage of energy utilization rate.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of distribution mode of light-concentrating solar heat-collection device, including spherical concentrating collector and Fresnel lens optically focused collection Hot device, the spherical concentrating collector and Fresnel lens concentrating collector linear laid out in parallel successively, the spherical It is provided with for receiving the receiver of heat at concentrating collector and Fresnel lens concentrating collector center optically focused, and is mutually communicated Connection.

It is arranged such, in identical arrangement distance, by addition arrangement Fresnel lens light and heat collection in original gap Device, by spherical concentrating collector and Fresnel lens concentrating collector, successively linear laid out in parallel can be to the full extent Utilization solar energy, even if due to the problem of sun angular cause spherical concentrating collector can block a part Fresnel Lens light gathering heat collector, but it remains to be changed in the middle of one day more solar energy into heat energy so that it is identical to account for the subsurface sun Energy utilization rate is higher, receiver is provided with the zonule that its directional light is converged, for receiving the heat of solar energy, by interior The heat-conducting medium in portion is transferred heat away from, and both are connected side by side, and receiver is identical for conducting heat.

Further arrange：The spherical concentrating collector is provided with tracking whirligig.

It is arranged such, the angle of sunshine is followed the trail of by photosensitive sensor, enables sunshine direct projection all the time spherical Face concentrating collector surface.

Further arrange：The receiver is cavity type receiver.

It is arranged such, cavity type receiver is cavity type receiver, it is empty by using cavity made by exotic material Chamber outside is equipped with the good resistant to elevated temperatures quartz glass of printing opacity, and inside is provided with wire netting to increase heat absorption and heating surface area, while in chamber Black matrix is provided with, heat absorption capacity is good, the sunshine of convergence produces higher temperature through quartz glass in chamber, and heat transfer medium is logical Cross in chamber and be heated to higher temperature output.

Further arrange：The spherical concentrating collector both sides are provided with X-type support, and receiver is in X-type support The heart is rotatably connected.

It is arranged such, receiver is rotatably connected by X-type support, while multiple spherical concentrating collectors can be caused It is connected side by side in alignment, and X-type support then plays a part of support, when whole spherical concentrating collector is rotated When, receiver can't be rotated in the middle of X-type support with overall, i.e., receiver is integrally fixed at all the time in relative position, And rotated by spherical concentrating collector.

Further arrange：The Fresnel lens concentrating collector support bar is highly the height at optically focused center to heat collector Degree.

It is arranged such, so can at utmost reduces the height of support bar, it is to avoid spherical concentrating collector is caused to hide Gear.

Further arrange：The Fresnel lens concentrating collector whole height is less than spherical concentrating collector spherical The height of bottom side.

Be arranged such, it is to avoid Fresnel lens concentrating collector on spherical concentrating collector by shade, so as to affect Heat energy is converted into spherical concentrating collector to solar energy to impact.

In sum, the utility model has the advantages that：Under identical floor space, the arrangement mode has Preferably solar energy utilization ratio, make use of to the full extent space, more solar radiant energies to be converted into heat energy.

Specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1：A kind of distribution mode of light-concentrating solar heat-collection device, as shown in figure 1, including spherical concentrating collector 1 and Fresnel lens concentrating collector 2, both linear laid out in parallel successively, the insertion of receiver 3 is connected, while in spherical Concentrating collector 1 is provided with tracking whirligig 4 so as to rotation can be tracked according to sunshine, while in spherical optically focused It is equipped with the receiver 3 for receiving heat at heat collector 1 and the center optically focused of Fresnel lens concentrating collector 2, and for cavity Type receiver 3, the marginal end of spherical concentrating collector 1 is additionally provided with X-type support 5, and receiver 3 is solid through the central rotation of X-type support 5 Fixed connection, and Fresnel lens concentrating collector 2 is then supported by support bar 6, and height extremely collects for optically focused center The height of hot device, but the not higher than height of the spherical bottom side of spherical concentrating collector 1.

Its main operational principle is as follows, saturating by spherical concentrating collector 1 and Fresnel under equal floor space The mode of mirror concentrating collector 2 both linear laid out in parallel successively can utilize to the full extent solar energy, when sun photograph When penetrating, spherical concentrating collector 1 can make sunlight direct projection all the time on surface according to whirligig 4 is followed the trail of, and Fresnel Lens light gathering heat collector 2 is divided into the lens of flat board the annulus of many, and each annulus is keeping the minute surface curve at respective radius Try one's best down thinner so as to wider optically focused scope, while heat build-up temperature is also at 300 degree to 1000 degree, in time at certain Time period is blocked by spherical concentrating collector 1, but because its larger optically focused scope also can be to carry out heat build-up, while Still there is the time being irradiated in other times section in the middle of whole one day, two kinds of heat collectors carry out conversion thermal energy by receiver 3, Receiver 3 is that, using cavity made by exotic material, cavity outside is equipped with the good resistant to elevated temperatures quartz glass of printing opacity, and inside is provided with , to increase heat absorption and heating surface area, while being provided with black matrix in chamber, heat absorption capacity is good for wire netting, and the sunshine of convergence is through quartzy glass Glass produces higher temperature in chamber, and higher temperature output is heated in heat transfer medium transit chamber, is finally reached too Sun can be converted to heat energy.The X-type support 5 of the both sides of spherical concentrating collector 1 can fix receiver 3, and receiver 3 can run through The center of X-type support 5 is fixed, while receiver 3 can also carry out straight line when multiple solar thermal collectors are discharged side by side Formula is fixed, and Fresnel lens concentrating collector 2 is then supported by the support bar 6 at two ends, therefore takes up an area face in identical Under product, identical time, this arrangement mode can preferably utilize solar energy, heat energy is translated into, so as to reach raising Solar energy utilization ratio.

The above embodiments are only that it is not to restriction of the present utility model, ability to explanation of the present utility model Field technique personnel can make as needed the modification without creative contribution after this specification is read to the present embodiment, but As long as all being protected by Patent Law in right of the present utility model.
