Abstract

The present invention relates to a quasi-uniaxial solar trajectory tracking transit system including a canopy, a case, a first positioning ring, a second positioning ring and a positioning pole. The canopy is a transparent hemisphere marked with a graduation line indicating elevation angles. The first positioning ring is a hollow body for receiving the second positioning ring. The two sides of the positioning ring have an axle respectively to connect with the case. The second positioning ring is a hollow fan-shape body for receiving the positioning pole. The second positioning ring has an axle perpendicular to the two sides of the axles of the first positioning ring for connecting to the first positioning ring thereby. The flange of the second positioning ring has a groove, and the central of the second positioning ring has an axle. A partial of positioning pole is hollow as a hollow pole and the other partial of the positioning pole is solid as a solid pole. A through hole is formed at the upper flange of the hollow pole and a sight is set at the lower flange thereof. The solid pole is axially connected to the axle of the second positioning ring.

Claims

1. A quasi-uniaxial solar trajectory tracking transit system comprising:

a case, having an opening at an upper flange thereof;

a canopy, having a transparent hemisphere marked with a graduation line indicating elevation angles, and a bottom flange covering said upper flange of said case;

a first positioning ring, including a hollow body having a smaller dimension than said opening of said case, having axles respectively on two sides to join to said case;

a second positioning ring, comprising a hollow fan-shape body having a smaller dimension than said first positioning ring, and an axle positioning perpendicular to two sides of said axles of said first positioning ring for connecting to said first positioning ring;

wherein a flange of said second positioning ring comprises a groove, and a central of said second positioning ring comprises an axle; and

a pole, having a part thereof being hollow as a thorough hole and another part thereof being a solid pole connected to said axle of said second positioning ring, and a through hole is formed at the upper flange of the hollow pole and a sight is set at the lower flange thereof;

wherein said first positioning ring is received in said opening of said case, said second positioning ring is positioned in said hollow portion of said first positioning ring, and said pole is positioned in said fan-shape hollow portion of said second positioning ring.

2. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein said opening of said case comprises a circular groove around said flange for receiving said canopy, and said case has graduation marks of azimuth around an outer surface in said canopy.

3. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein said two sides of said case are connected to said axle of said first positioning ring having graduation marks of latitude.

4. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein said first positioning ring comprises a regulator hand at said axle for adjusting angles according to a local latitude.

5. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein said two sides of said outer flange of said first positioning ring connected to said axle of said second positioning ring comprises graduation marks of time.

6. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein said axle of said second positioning ring comprises a regulator hand for adjusting time.

7. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein a periphery of said groove of said second positioning ring comprises a graduation for said pole to set dates.

8. A quasi-uniaxial solar trajectory tracking transit system according to claim 1, wherein a laser indicator pen is installed in said through hole or on said sight.

9. A quasi-uniaxial solar trajectory tracking transit system according to claim 8, wherein said laser indicator pen is inlaid or screwed to an inner side of said through hole or on said sight.

10. A quasi-uniaxial solar trajectory tracking transit system comprising:

a case, having an opening at an upper flange thereof;

a canopy, comprising a transparent hemisphere marked with a graduation line indicating elevation angles, and a bottom flange covering said upper flange of said case;

a first positioning ring, comprising a hollow body having smaller dimension than said opening of said case, having axles respectively on two sides to join to said case; and

a second positioning ring, comprising a solid body having a smaller dimension than said first positioning ring, and an axle positioned perpendicular to two sides of said axles of said first positioning ring for connecting to said first positioning ring;

wherein a flange of said second positioning ring comprises a through hole extending to a center of said second positioning ring with a sight therein.
