Abstract
The utility model discloses a device for demonstrating revolution of the sun. The device comprises a base, a central column fixed on the base, a sun model fixed on the top of the central column, an elliptical rail arranged around the central column and an earth model which is arranged on the elliptical rail and capable of rotating along the elliptical rail, wherein a plurality of inclined supporting rods are arranged between the elliptical rail and the central column; an indicating arrow is arranged at each of intersections between the elliptical rail and the long axis of the elliptical rail as well as between the elliptical rail and the short axis of the elliptical rail; and a nameplate is suspended below each indicating arrow. The utility model has the advantages that: (1) the device has a simple structure; (2) through the device, the whole revolution process of the earth around the sun can be intuitively demonstrated, so that students can understand the revolution theory of the earth deeply, and the learning interesting is enhanced; and (3) through the device, the positions of the earth on the elliptical rail at four solar terms, namely spring equinox, summer solstice, autumnal equinox and winter solstice are intuitively marked.
Description
Technical field
The utility model relates to a kind of geographical teaching apparatus, particularly a kind of sun revolution apparatus for demonstrating.
Background technology
At present, in geographical teaching practice, when lecturing the principle that the earth revolves around the sun, owing to there is not special apparatus for demonstrating, students is deep inadequately to the understanding of this principle, thereby not only influences teaching efficiency, and has reduced the interest of study.
Summary of the invention
The problem that the utility model will solve is: provide a kind of simple in structure, deepen the student to the understanding of revolution of earth principle and strengthen the interesting sun revolution apparatus for demonstrating of study.
In order to solve the problems of the technologies described above; The sun revolution apparatus for demonstrating of the utility model; Comprise base, be fixed on newel on the base, be fixed on the newel top solar model, be arranged on the elliptical orbit around the newel and be arranged on the elliptical orbit earth model that can rotate along elliptical orbit, be provided with some hounds between said elliptical orbit and the newel.
The earth residing position on elliptical orbit when indicating the Spring Equinox, the Summer Solstice, the Autumnal Equinox and Winter Solstice; The sun revolution apparatus for demonstrating of the utility model; The intersection point place of said elliptical orbit and elliptical orbit major axis and minor axis respectively is provided with an arrow, and the below of said arrow is hung with a nameplate.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) can demonstrate out the whole process that the earth revolves around the sun intuitively, deepen the understanding of student, strengthen the interest of study the revolution of earth principle; (3) indicate the Spring Equinox, the Summer Solstice, the Autumnal Equinox and Winter Solstice position of the earth on elliptical orbit during four solar term intuitively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, elliptical orbit, 2, solar model, 3, arrow, 4, nameplate, 5, earth model, 6, hound, 7, newel, 8, base.
Embodiment
As shown in Figure 1; The sun revolution apparatus for demonstrating of the utility model; Comprise base 8, be fixed on newel 7 on the base 8, be fixed on newel 7 tops solar model 2, be arranged on the elliptical orbit 1 around the newel 7 and be arranged on the elliptical orbit 1 earth model 5 that can rotate along elliptical orbit 1, be provided with some hounds 6 between said elliptical orbit 1 and the newel 7; Said elliptical orbit 1 respectively is provided with an arrow 3 with the intersection point place of elliptical orbit 1 major axis and minor axis, and the below of said arrow 3 is hung with a nameplate 4.
In the time of concrete the demonstration; On the nameplate 4 of four arrow 3 belows respectively with " Spring Equinox ", " Summer Solstice ", " Autumnal Equinox " and " Winter Solstice "; Earth model 5 rotates counterclockwise along elliptical orbit 1 from nameplate 4 beginnings with " Spring Equinox "; Pass through successively with the nameplate 4 in " Summer Solstice ", " Autumnal Equinox " and " Winter Solstice ", get back to nameplate 4 places at last, accomplish a period of revolution with " Spring Equinox ".
The sun revolution apparatus for demonstrating of the utility model can be demonstrated out the whole process that the earth revolves around the sun intuitively, deepens the understanding of student to the revolution of earth principle, strengthens the interest of study.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
