Embodiment; As Fig. 1, Fig. 2, shown in Figure 3, illumination pattern rail groove 1 is arranged on illumination pattern form 2 middle parts, and is fixed on illumination pattern support 14 left upper ends, and its upper right side is provided with gimbals rotation axis 13, its upper end connects gimbals 12 with gimbals rotational positioning knob 20, and supports the terrestrial globe structure; Altitude of the sun index dial support 25 is parallel with illumination pattern support 14 bottoms, is connected and fixed altitude of the sun by altitude of the sun index dial rotation axis 24, altitude of the sun index dial positioning knob 23 and props up plate 34, and support observation element in morning and evening.

As shown in Figure 1 and Figure 2, the terrestrial globe structure is rotated adjusting knob 10 and gimbals circular orbit rotation axis 11 heads in gimbals 12 upper ends by gimbals circular orbit 8 usefulness gimbals retainer springs 9, gimbals circular orbit, terrestrial globe annular period of the day from 11 p.m. to 1 a.m support 4, the terrestrial globe annular support period of the day from 11 a.m. to 1 p.m 19, constantly enclose 7 and gimbals circuit orbit groove 16 by Instrument for surveying solar time and azimuth posture adjustment handle 15 heads in gimbals circular orbit 8 upper ends; Constantly enclose middle part, 7 left side four seasons change lever 6 is set; Globe sphere 3 installs portion within it; The left half side of globe sphere 3 is translucent night hemisphere 5, the earth's axis 18 two ends down disposed thereon, and confused coil 30 and point of contact that coil 31 in ruddy morning, blue look are installed on the night hemisphere 5 indicate 17.

As Fig. 1, shown in Figure 3, observation element was arranged on altitude of the sun by sunray pointer rail groove 22 and propped up plate 34 middle parts morning and evening, altitude of the sun index dial 21 devices are at its left end, 2 translation wheel 29 devices are on translation wheel support 33, connect by translation wheel belt 26, and be in the same place with sunray pointer handle 27, sunray pointer 28 devices.

Embodiment 1: in use, 1, pull four seasons change lever 6, annular globe bracket 4 can slide in translucent night hemisphere rail groove, thus producing the four seasons changes.The semicircle of ring support is a purple period of the day from 11 p.m. to 1 a.m circle 4, and second half encloses 19 for peony the period of the day from 11 a.m. to 1 p.m.Transparent moment circle 7 is housed in this support, can looks into the local time of any warp.The confused coil 30 and point of contact 17 signs of coil 31 in ruddy morning, blue look are installed on the night hemisphere 5.See through illumination pattern form 2, can see the Instrument for surveying solar time and azimuth overall picture that is installed on the gimbals 12, pull posture adjustment handle 15, can adjust the attitude of Instrument for surveying solar time and azimuth arbitrarily, and can on the illumination pattern support, put into corresponding illumination pattern.
