Abstract
The invention relates to a power-driven sun, earth and moon movement demonstration instrument which especially can intuitively demonstrate the spatial state of the sun, the earth and the moon when the earth revolves around the sun and rotates and the moon rotates around the earth. The motor-driven sun, earth and moon movement demonstration instrument is characterized in that a moon model and a moon model strut are connected; an earth model and an earth model strut are connected; a rotation gear of the earth model is fixed on the earth model strut; a sun model gear is fixed on a sun model strut; the rotation gear of the earth model and the sun model gear are tightly combined; the sun model and the sun model strut are connected; a supporting rod, the earth model strut and the sun model strut are connected; in a shell, a driven gear is fixed on the sun model strut; a driving gear is fixed on a motor shaft of a direct-current motor; the driving gear and the driven gear are tightly combined; and a power box is arranged in the shell. Because of adoption of the technical scheme, the power-driven sun, earth and moon movement demonstration instrument has the advantages and the positive effects of simple and clear structure and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of electronic sun, the earth, moon motion demonstrator, can demonstrate intuitively especially that the earth revolves around the sun, the spatiality of rotation and the moon three balls when the earth rotates.
Background technology
At present, the common terrestrial globe of selling on the market can only react the characteristic in each geographic position on the earth statically, can't express dynamically intuitively comprehensively that the earth revolves around the sun, the spatiality of rotation and the moon three balls when the earth rotates.
Summary of the invention
The purpose of this invention is to provide a kind of electronic sun, the earth, moon motion demonstrator; Can not only demonstrate intuitively that the earth revolves around the sun, the spatiality of rotation and the moon three balls when the earth rotates, and can demonstrate the variation, sunshine of subsolar point under the different conditions variation in the light area of the earth and moonscape.
The objective of the invention is to realize like this: the present invention is made up of moon model, moon model pole, earth model, earth model pole, earth model rotating gear, solar model gear, solar model, solar model pole, pressure pin, shell, follower gear, power pack, motor shaft, driving gear and direct current generator; It is characterized in that: moon model links to each other with moon model pole; Earth model links to each other with earth model pole, and the earth model rotating gear is fixed on the earth model pole, and the solar model gear is fixed on the solar model pole; Earth model rotating gear and the close combination of solar model gear; Solar model links to each other with solar model pole, and pressure pin links to each other with earth model pole, solar model pole, in shell; Follower gear is fixed on the solar model pole; Driving gear is fixed on the motor shaft of direct current generator, the close combination of driving gear and follower gear, and power pack is in the enclosure.
Because adopt technique scheme, advantage and good effect that the present invention had are: simple in structure, come into plain view, cost is not high yet.
