Abstract
The utility model a moon operation demonstration instrument, which includes a base, a connecting arm, a terrestrial globe and a moon, wherein the connecting arm is assembled on the base, the terrestrial globe and moon are connected to the connecting arm through uprights, the uprights are respectively connected by gear set, and a handle is provided on one side of the connecting arm. The moon operation demonstration instrument livingly depicts the moon variation of the moon, the synchronous rotation of the moon and the appear and dispappear time of the moon, and the like natural phenomenon, to overcome the abstraction teaching, and deepen the visual understanding of students to control celestial body operation variation.
Description
Technical field
The utility model relates to a kind of moon operation demonstrator.
Background technology
Celestial operating rule in the daily teaching process in default of the instrument of ocular demonstration, it is abstract uninteresting that feasible teaching becomes, the student is difficult to be given full play to astronomical enthusiasm and enthusiasm, directly influenced teaching efficiency, therefore be badly in need of wanting a kind of object teaching instrument that can simulate celestial body relative motion rule, so that overcome abstract teaching, deepen the intuitivism apprehension of student to the motion of celestial body Changing Pattern.
Summary of the invention
The purpose of this utility model is to provide a kind of moon operation demonstrator that can simulate moon moving law.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows: a kind of moon operation demonstrator, it comprises base, linking arm, terrestrial globe and the moon, described linking arm is assembled on the base, the described terrestrial globe and the moon link to each other with linking arm by vertical rod respectively, described vertical rod links to each other by gear set respectively, and linking arm one side is provided with handle.
The utility model moon operation demonstrator compared with prior art has following beneficial effect: can simulate the motion state of the moon intuitively, the consequent various spontaneous phenomenons of scientific explarnation.
Description of drawings:
Fig. 1 is a stereographic map of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
Please refer to shown in Figure 1, a kind of moon operation of the utility model demonstrator, it comprises base 1, linking arm 2, terrestrial globe 41 and the moon 51, described linking arm 2 is assembled on the base 1, the described terrestrial globe 41 and the moon 51 link to each other with linking arm 2 by vertical rod 4 and 5 respectively, described vertical rod 4 and 5 links to each other by gear set respectively, and linking arm one side is provided with handle 3.Described gear set comprises driving wheel 43,53 and engaged wheel 42,52, and described adjacent driving wheel links to each other by bearing.
Need reverse driving handle during use, make the moon around revolution of earth, the observer can see that moon visible face gets the light and shade looks and takes place continuously to change.In the process of the demonstration phases of the moon, the observer can also see the synchronous rotation of the moon, promptly centers on the rotation of revolution of earth, that is the rotation period equals the phenomenon of the period of revolution.
