PROBLEM TO BE SOLVED: To provide a quasi-uniaxial solar trajectory tracking theodolite which accurately can observe and simulate amplitude, elevation angle and trajectory of the sun. SOLUTION: The theodolite includes a box 2 with an aperture 21 on its upper edge; a semi-spherical cover 1 covering rim of the aperture 21 on the box 2; the first locating ring 3 which is hollow and provided with a pivot axis 31 connected to the box 2 on both sides; and the second locating ring 4 which is sector hollow and provided with a pivot axis 41 connected to the first locating ring 3 on both sides perpendicular to the pivot axis 31 of the first locating ring 3 provided with a recessed groove 42 on the rim and a central axis 43 in center. Furthermore, a hollow cylinder 52 is prepared on one end, while a solid-core cylinder 54, rotatably-mounted on the central axis 43 of the second locating ring 4, is prepared on the other end. The hollow cylinder 52 includes a positioning column 5 with a through-hole 51 on upper edge and a reference center 53 on lower edge. COPYRIGHT: (C)2011,JPO&INPIT |
