Abstract
The utility model relates to a projection space-time globe which can provide space-time transformation information in the rotation and the revolution of the earth. The projection space-time globe has the structure that a driving mechanism and a light projection mechanism are arranged in a globe. The driving mechanism is driven by a gear to drive the globe and the light projection mechanism to rotate, and the light projection mechanism makes the surface of the globe ddisplay a black hemisphere and a white hemisphere that are divided vertically and a light spot. In operation, the rotation of the globe and the revolution of the surface projection thereof reflect the space-time information, sich as days, nights, dates, worldwide times, terminator lines, subsolar projecting points, etc. The projection space-time globe is not only appropriate for teaching natural geography, but also can be used as a worldwide clock and an ornamental art ware.
Description
The utility model is a kind of space-time globe that adopts light projection's reflection earth in rotation and revolution space-time transformation in service.It can provide space-time transformation relevant multiple information intuitively: daytime, night, terminator, date, zebra time and subsolar point etc.
At present the product of this technical field is a globe traditionally, and it can only reflect geographic(al) spatial information.Have only when when a luminophor (sun) revolves round the sun, could reflect multiple space time information in conjunction with itself rotation.
The purpose of this utility model is on the basis of globe traditionally, increases the light projection of reflection revolution situation, combines the space time information that the reflection earth moves with the rotation of terrestrial globe itself.
The utility model technical scheme for achieving the above object is, in terrestrial globe interior arrangement driving mechanism and mechanism of light projection, drive mechanism terrestrial globe and mechanism of light projection rotate, light projection makes globe surface be rendered as two hemisphere of black and white and a luminous point of vertical separation, the revolution of terrestrial globe rotation in service and its surface projection realizes and the reflection space-time transformation.
Owing to adopt technique scheme, the reflection space time information is truly directly perceived, and form is easy to be accepted by people to globe is similar traditionally.
The utility model has following accompanying drawing:
Accompanying drawing 1. space-time globe structural representations
Accompanying drawing 2. projection lamp synoptic diagram
1. bases, the 2. day moon in season index dial, 3. frameworks, 4. graduated time rings, 5. terrestrial globes, 6. axis of rotation, 7. projection lamps, 8. hollow shafts, 9. needle bearings, 10. gear trains, 11. driving mechanisms, 12. horizontal bearing pin 13. optically focused lampshades among the figure
The utility model has following three kinds of embodiment:
1 plain edition; 2 power types; 3 clock-types;
Below in conjunction with accompanying drawing, describe its structural principle in detail:
The axis of rotation (6) is 66.5 degree angles with the surface level of base (1), and terrestrial globe (5) is fixed together with the axis of rotation (6) and carries out rotation, and corresponding graduated time ring (4) can obtain the time at that time of same longitude region; Hollow shaft (8) and the axis of rotation (6) coaxial cable; Framework (3) is fixed together with hollow shaft (8) and revolves round the sun; Projection lamp (7) links to each other with hollow shaft (8) by two bearing pins (12), projection lamp (7) can be rotated around bearing pin (12), the center of gravity of utilizing projection lamp (7) on the lower side, the black and white projection interphase of projection lamp under action of gravity (7) therefore can be converted into rotatablely moving of hollow shaft (8) revolution motion that axis and level are 90 degree all the time perpendicular to surface level; Projection lamp (7) causes the black and white projection and the direct projection luminous point of band zone of transition by optically focused lampshade (13).Pointer on the framework (3), Ji Yue, the date position of corresponding Ji Yueri index dial (2) indication revolution.Driving mechanism (11) drives the axis of rotation (6) simultaneously by gear train (10) and hollow shaft (8) is realized operation automatically.In order to reduce rotational resistance, each all is furnished with needle bearing (9) supporting.
Plain edition of the present utility model adopts manual operation.There are not driving mechanism (11) and gear train (10).Rotating frame (3) at first during operation makes pointer refer to date position on the same day, and rotate the globe then (5) aim at somewhere time scale at that time with the warp in somewhere, finish above-mentioned adjustment, and this terrestrial globe just is in space-time position at that time on the same day.Just can obtain following information very intuitively: the time at that time all over the world; Any place was daytime or night or dawn and dusk at that time; The direct projection place of the sun and latitude etc.
Claims (2)
1. terrestrial globe, the rotation axis is horizontal by 66.5 degree, it is characterized in that: a cover is housed in terrestrial globe inside can be according to the mechanism of light projection of the two axis rotations that intersect vertically, its center of gravity is lower than the transverse bolt axis, this mechanism rotates according to the rotation axis, and two hemisphere of black and white and the luminous point that are projected in the vertical separation of globe surface revolve round the sun according to Z-axis.
2. terrestrial globe according to claim 1 is that the rotation of globe and light projection revolution drivingly realizes space-time transformation simultaneously through a tooth difference gear by a cover driving mechanism.
