Abstract
The utility model discloses an earth revolution demonstration instrument comprising a globe, wherein the globe is arranged on an elliptical track on a bottom plate, and the middle part of the elliptical track is provided with a sun simulator, on which a sun light simulator is crosswise arranged in a penetrating manner. The demonstration instrument is simple in structure, reasonable and scientific in design, and vivid in demonstration image, and impresses students, thus being convenient to understand.
Description
Technical field
The utility model belongs to the teaching aid technical field, particularly a kind of revolution of earth demonstrator.
Background technology
At present, in geographical course teaching, the teacher is many to explain geographical knowledge with wall chart, yet these wall charts can not reflect actual geographical phenomenon fully, need the teacher to explain more fully, geographical knowledge is understood, is received in the imagination thinking of mobilizing students.But some geographical phenomenon relative complex only can't be understood and be received fully with student's imagination space, and for example revolution of the earth and rotation phenomenon are depended merely on terrestrial globe and wall chart and can't be annotated it and truly include, and the student understands quite difficulty.
The utility model content
The purpose of this utility model provides a kind of simple in structure, revolution of earth demonstrator of being convenient to understand.
For achieving the above object, the technical solution of the utility model is: a kind of revolution of earth demonstrator, comprise terrestrial globe, and described terrestrial globe is located on the elliptical orbit on the base plate, the elliptical orbit middle part is provided with the solar simulation body, intersects on the solar simulation body to be equipped with the sunray analogue body.
Compared with prior art, the beneficial effects of the utility model are: terrestrial globe is along revolving round the sun around the solar simulation body on the elliptical orbit on the base plate, intersect on the solar simulation body and be equipped with the sunray analogue body, simple in structure, reasonable in design, science, the demonstration lifelike image makes a profound impression to the student, is convenient to understand.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Revolution of earth demonstrator as shown in Figure 1, its terrestrial globe 1, terrestrial globe 1 comprises spheroid 11, semi arch calibrating jig 12, base (not shown in the accompanying drawing) and is connected the vertical rack (not shown in the accompanying drawing) of semi arch calibrating jig 12 and base, spheroid 11 rotates and is arranged in the semi arch calibrating jig 12, and spheroid 11 rotates the simulation earth rotation in semi arch calibrating jig 12.Except above-mentioned terrestrial globe 1, the utility model also includes base plate 2, solar simulation body 3 and sunray analogue body 4, on base plate 2, be provided with elliptical orbit 5, solar simulation body 3 is located at the middle part of elliptical orbit 5, on solar simulation body 3, intersect and be equipped with sunray analogue body 4, the sunray analogue body 4 that passes solar simulation body 3 at grade, and direct projection is on the spheroid 11 of terrestrial globe 1.Terrestrial globe 1 rotates along elliptical orbit 5, finishes the revolution of earth demonstration.
