Fig. 2 a is the schematic diagram of accumulation unit according to an embodiment of the invention.As shown in the figure, applicant points out, in order to realize gathering solar energy, in the most basic embodiment, the spoke wheel structure of often seeing in solar energy collecting equipment utilization life of the present invention, for example bicycle and electric motor car wheel, as the main support structure of accumulation unit, accumulation unit consists essentially of the spoke wheel 201 that two subtends are placed, the oblique tension part 106-1 of two parallel fixing multiple the first connectors 106 of width wheel is interfixed and tiltedly connected, the allotment support member 106-2 of the first connector 106 interfixes and is supported in the wheel rim of two spoke wheels 201, make the spoke wheel 201 and the first connector 106 that are arranged in parallel form tubular construction, overall construction intensity is greatly improved.Between two width wheels 201, be also provided with solar concentrator 204 and receiver 205, solar concentrator 204 and receiver 205 are parallel to each other.The speculum of solar concentrator 204 can be lens pillar or Fresnel Lenses or parabola groove speculum or Fresnel array mirror, can take various focusing curved surfaces, by solar light focusing in receiver 205 places.Width wheel 201 with and between solar concentrator 204 and receiver 205 can around the central support shaft 217 of spoke wheel 201 central axis positions, (this figure indicate, and b) rotates referring to Fig. 2.
Applicant particularly points out, and the first connector 106, the second connector 107, the 3rd connector 108 can be such as the high strength flexible connecting devices such as steel wire or high-intensity fine steel tube jockey.
In an example, there is a flower-drum 211 at the spoke wheel center that is positioned at this spoke wheel 201 of support, multipair spoke link wheel rim 201 and flower-drum 211, thereby the overall structure of formation spoke wheel 201.
In another example, a bascule 209, be for example means for equalising or counter weight device, arrange symmetrically with respect to axle center and the described solar concentrator 204 of described spoke wheel 201, the moment of torsion producing because of rotation for solar concentrator described in balance 204.In the time that drive unit (not shown) moves, can order about bascule 209, solar concentrator 204 and spoke wheel 201 and rotate around the central support shaft 217 through spoke wheel 201 center flower-drum together.Due to bascule 209 and solar concentrator 204 balances, can be safer and stably move so can make drive unit save power and solar energy collecting equipment.Be counter balance torque at the equipping rules of following bascule, minimize under the prerequisite of the rate of being in the light, solar concentrator and bascule are arranged symmetrically, make solar energy collecting equipment reach balance, reduce the energy loss of drive unit.Described solar concentrator 204 is arranged between two spoke wheels 201.Distance (or length of focusing unit) between the length dimension of this solar concentrator 204 spoke wheel 201 adjacent with two is corresponding.Described solar concentrator 204 can rotate and lock around the central support shaft of described spoke wheel 201 217.Solar concentrator 204 has the focal line of certain length, and the line in this focal line and the axle center of adjacent spoke wheel 201 is consistent or be positioned at the upper part of spoke wheel.Arrange that on the opposite of solar concentrator 204 bascule 209 is to reach mechanical balance, thereby it is more stable and smooth and easy to contribute to solar concentrator 204 to move.
Fig. 2 b has illustrated the corresponding relation of the adjacent width wheel between the accumulation unit of two series connection.Left width wheel and right width wheel 201 belong to respectively adjacent but different focusing units.A base carrier 102 is between two width wheels 201.The spacing of two spoke wheels 201 is greater than the width of base carrier 102.The central axes of spoke wheel 201.The spoke wheel central shaft that central support shaft 217 is passed separately, is supported by base carrier 102, and central support shaft 217 can be rotated or fix relative to base carrier 102.Thus, two width wheels 201 are stablized to be placed on platform, for example ground.
Although become an array with solar energy collecting equipment shown in Fig. 2 b with three serial arranged in form of series connection at accompanying drawing 2a, but, applicant particularly points out, in practice, solar energy collecting equipment of the present invention can be arranged to more series connection series, and can pass through the first connector 106, the second connector 107, the 3rd connector 108 between this more series connection series, such as steel wire or other high-strength flexible jockey are arranged to solar energy collecting equipment array, and the spoke wheel axle center of the spoke wheel bracing or strutting arrangement of each serial array is coaxial.Certainly, the first connector 106, the second connector 107, the 3rd connector 108 can also be taked other type of attachment, or adopt other material to make.Fix because spoke wheel adopts the high strength flexible connecting member tensioning such as steel wire cheaply each other, thereby can strengthen the mechanical strength of whole solar energy collecting equipment or its array.Spoke wheel brings the serious problem that is in the light can to solar energy collecting equipment simultaneously, needn't consider anti-blown sand pollution problem, greatly reduces materials'use, reduces costs.
Fig. 3 has illustrated tubular construction and corresponding relation between two focusing units in parallel.Between these two accumulation units, interfix by the oblique tension part 106-1 of the first connector 106 tiltedly connect, the allotment support member 106-2 of the first connector 106 interfixes supports, formation tubular construction; By the allotment support member 107-2 of the second connector 107 interfix support, by the oblique tension part 107-1 of the second connector 107 tension that interfixes, or for example, fix tension with basis (ground), form horizontal connection group string, strengthen lateral stability.For the object of signal, many parts are omitted, such as solar concentrator.
Can find out in conjunction with upper figure, in each series connection series, the axis parallel of receiver and spoke wheel 201, and its two ends are arranged on the circumference of wheel rim of spoke wheel 201.Receiver 205 is positioned on the focal line of solar concentrator 204, for absorbing the sunshine being reflected by described solar concentrator 204.Drive unit (all not marking in figure) is arranged in the ad-hoc location of described spoke wheel 201, can be toothed belt transmission or line synchro transmission, impels described solar concentrator 204 to rotate around the central support shaft 217 through spoke wheel central shaft.Under the effect of drive unit, solar concentrator 204 is followed the tracks of the change in location of the sun and sunshine is reflexed to described focal line.
