Description
Technical field
The utility model relates to a kind of geographical teaching apparatus for demonstrating, specifically a kind of earth rotation and revolution demonstration teaching aid.
Background technology
In geographical teaching, often relate to the autobiography of the earth and the problem that revolves round the sun around the sun, mostly being the classroom in the teaching tells about, no teaching aid demonstration, and about nature celestial body sidereal day and solar day, it is intricate that earth rotation, revolution etc. are calculated, cause the study of this part content uninteresting, theory loses contact with reality very serious, has influenced student's results of learning.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and providing a kind of can be familiar with to student image, the earth rotation of improving the quality of teaching and revolution demonstration teaching aid.
The technical solution of the utility model realizes in the following manner, earth rotation and revolution demonstration teaching aid, comprise framework, solar model, slow speed motor one, pivot arm, circular guideway, slow speed motor two, earth model, support, battery and switch, it is characterized in that: circular guideway is installed in the framework, its circle centre position fixedly installs slow speed motor one, above the slow speed motor one solar model is set, its line shaft connects pivot arm, the other end of pivot arm arranges slow speed motor two, slow speed motor two is slidingly connected with circular guideway, earth model is set on it, and the framework lower left corner arranges battery and switch, and framework bottom is provided with support.
Described slow speed motor one driven rotary arm rotates, and allows earth model center on the solar model revolution, and described slow speed motor two drives the earth model rotation.
Described framework bottom is provided with support, is used for support frame.
Described battery is connected with slow speed motor one, slow speed motor two by lead with switch.
The utility model has the advantages that: this device can be simulated the rotation of the earth, circumsolar revolution automatically, is convenient to the student and understands, and improves student's learning efficiency.
Description of drawings
