Abstract
The invention relates to a method for tracking and catching sunlight. The method comprises the steps: calculating out a solar altitude h and a solar azimuth r, rotating a center axle of a condensing lens to form the angle h with a vertical direction and form the angle r with a horizontal direction; detecting whether a rendezvous point formed by sunlight which irradiates on the condensing lens is overlapped with a focus of the condensing lens or not; if yes, accounting for that the sunlight is accurately tracked and caught; if not, rotating the rendezvous point to the direction of the focus; and carrying out detection and adjustment again. According to the method for tracking and catching the sunlight, the condensing lens is enabled to accurately track the sunlight in a real time, after the focus of the condensing lens is coupled with an optical fiber end face, sunlight after focusing can be enabled to completely pass through an optical fiber with diameter of 1mm, and use efficiency of the sunlight is effectively improved.
Description
Technical field
The present invention relates to a kind of method of following the tracks of sunshine when utilizing solar heat.
Background technology
Along with the sternness increasingly of world energy sources situation, solar water, photovoltaic and photothermal generating, solar light collection and conduction, solar cooker etc. as a kind of important fossil energy alternative, have been subject to the favor of countries in the world governments.Particularly in sun power high-end applications field---sunlight collecting transmission system! Through developed country's five more than ten years development tests such as English, U.S., days, entered practical engineering field and precision agriculture research, military and national defense, large-scale recovery centre, sunbath, the daily illumination and sterilization of family, basement, underground garage lighting, large supermarket, hotel, large conference room, commercial office building etc. lighting field on daytime now.
But the sunlight collecting transmission system of using at present all can not realize trace trap sunshine accurately, thereby can't utilize efficiently sunlight heat.
Summary of the invention
The present invention aim to provide a kind of can real-time high-precision the method for ground trace trap sunshine.
The method of trace trap sunshine of the present invention comprises:.
⑴ determine the number of days n of time in 1 year of trace trap, and hourage T(was in 24 hours) and the geographic latitude φ of trace trap point.
⑵ calculate solar hour angle t
t?＝(T-12)×15°；。
⑶ calculate solar declination δ
δ?=23.45?sin(360?×?(284+n)/365)。
⑷ calculate sun altitude h
sin?h＝sinφ?sinδ＋cosφ?cosδcos?t；。
Calculate solar azimuth γ
cosγ?=(sin?h?sinφ?-?sinδ)/cos?h?cosφ；。
⑷ turn to the central shaft of collector lens and become the h angle with vertical direction, from the horizontal by the γ angle;
⑸ whether the convergent point that detect the sunshine formation that shines on collector lens overlaps with the focus of collector lens;
⑹ if overlap, accurate trace trap sunshine is described;
⑺ if do not overlap, rotate to focus direction;
⑻ whether the convergent point that again detect the sunshine formation that shines on collector lens overlaps with the focus of collector lens, if overlap, accurate trace trap sunshine is described; If do not overlap, repeating step ⑺;
⑼ repeating step ⑸, ⑹, ⑺ are until accurate trace trap sunshine.
Preferably, when rotating to focus direction, the vertical angle of rotation and horizontal angle are 0.00002 degree.
The present invention can make collector lens accurately and follow the tracks of in real time the sun, after collector lens focus and fiber end face coupling, can make the sunshine after focusing pass through the optical fiber of diameter 1mm fully, effectively improves the utilization factor of sunshine.
Embodiment
The below elaborates to the present invention, and the explanation of the invention is not limited.The present invention specifically implements according to the following steps:.

⑵ calculate solar hour angle t
t?＝(T-12)×15°；
If for example the mornings 9 point, t=(9-12) * 15 °=-45 °
If afternoons 3 point, t=(15-12) * 15 °=45 °.
⑶ calculate solar declination δ
δ?=23.45?sin(360?×(284+n)/365)。
⑷ calculate sun altitude h
sin?h＝sinφ?sinδ＋cosφ?cosδcos?t；。
Calculate solar azimuth γ
cosγ?=(sin?h?sinφ?-?sinδ)/cos?h?cosφ；。
⑸ turn to the central shaft of collector lens and become the h angle with vertical direction, from the horizontal by the γ angle;
Whether the convergent point that detection shines the sunshine formation on collector lens overlaps with the focus of collector lens;
⑹ if overlap, accurate trace trap sunshine is described;
⑺ if do not overlap, rotate to focus direction;
⑻ whether the convergent point that again detect the sunshine formation that shines on collector lens overlaps with the focus of collector lens, if overlap, accurate trace trap sunshine is described; If do not overlap, repeating step ⑺;
⑼ repeating step ⑸, ⑹, ⑺ are until accurate trace trap sunshine.
