Preferably, described support comprises fixed frame (8), rotating frame (10) and bent axle (9), and described two reflective parabolic cylinderes (1,2) are fixed on fixed support (8), it is upper that fixed support (8) is fixed on bent axle (9), and bent axle (9) is connected on rotating frame (10).
Preferably, pitching motor and transmission system (11) are also housed on described rotating frame (10), the linear axis rotation of described fixed frame (8) and described reflective parabolic cylinder (1,2) flexing axle (9) under the drive of pitching motor and transmission system (11) mounted thereto.
Preferably, described rotating frame (10), bent axle (9), fixed frame (8) and described reflective parabolic cylinder (1,2) the integral body central axis (15) around rotating frame under the drive of azimuth-drive motor and transmission mechanism (14) rotates.
Preferably, on rotating frame (10) top, place energy receiving terminal (16).
Preferably, described two reflective parabolic cylinderes are connected and fixed formation " to mirror " in specific relative position mode, and the two relative position is fixed.
Preferably, the described geometry to the feature of two reflective parabolic cylinderes in mirror is expressed and is: in a three-dimensional cartesian coordinate system XYZ, the equation that makes one-level cylindrical mirror is Z=X^2/4f, the focal length that wherein f is this parabolic equation., according to definition, in Y=0 plane, the equation of the directrix S of one-level cylindrical mirror is also Z=X^2/4f, its focus be F1 (0,0, f); There is one through the normal P of plane X=0 of a F1.In the plane of X=0, take P as directrix, with a F2 (0,0, be f-2r) focus, having equation is the parabola T of Z=-Y^2/4r+f-r, wherein r is the summit of parabola T and the distance between normal P.Take T as directrix, take a straight line that is parallel to X-axis as bus slides along T, form secondary cylindrical mirror, its equation is Z=-Y^2/4r+f-r.“
Preferably, " to mirror " take one through focal point F 2 and the straight line that is parallel to the bus of one-level cylindrical mirror, be trunnion axis, under controller is controlled, automatic rotation is realized the following in elevation to the sun.The normal that " to mirror " and trunnion axis be take through the plane Z=0 of some F2 is that vertical pivot automatic rotation under controller is controlled is realized to be followed the tracks of the orientation of the sun.System is placed an energy receiving terminal in focal point F 2 places of " to mirror ".
Through light path vector analysis, author finds the process that directional light reflect and focuses on through the paraboloid of revolution, can be decomposed into the during focusing in latter two orthogonal vector direction of elder generation, and the process focusing on each direction vector therein only relates to parabolic cylinder.Therefore,, when light beam is after the successive reflex of two parabolic cylinderes, can be grouped together in a point.
So in fact these two parabolic cylinderes have formed a pair of minute surface, are called as " to mirror ".Each width " to mirror " has a focus, and is unique focus.The present invention has realized by the attitude of " to mirror " is controlled, and makes the running orbit of its sun-tracing, guarantees that sunlight focus point position maintains static, and rests on all the time on solar energy receiving terminal.
Of the present invention two large advantages are: one, without using the paraboloid of revolution, and only use parabolic cylinder, significantly reduced manufacturing cost; Two, focus point position is fixed, and has therefore exempted the motion burden of solar energy receiving terminal one end.
