Full-simulating sun-moon-earth instrument

Abstract

The invention relates to a fully simulated three-sphere instrument, which is composed of a heliospheric rotation and light-emitting device, an earth and moon rotation and revolution device, an earth-moon upgrade device, and a speed regulation and control circuit. The outer end of the long arm of the earth revolution device is a ground The lunar lifting device is equipped with the earth's rotation and the moon's revolution, rotation and lifting devices. These devices revolve around the heliosphere in the center. It is characterized in that the earth revolves around the sun and the moon revolves around the earth. The movement makes the earth's revolution orbital plane and the sun's equatorial plane, the moon's orbital orbital plane and the earth's equatorial plane form the due intersection angle; the electronic speed regulation makes the rotation and revolution speed ratio of the three spheres similar to the actual one; The astrology is similar to the real astrology. It can demonstrate the operation of the three spheres in a comprehensive, real, three-dimensional and vivid way, and reveal its operation law and the resulting celestial phenomena and natural phenomena in a simple and fast way. It has practical significance for popularizing astronomical knowledge.

Description

technical field [0001] The invention belongs to a three-sphere demonstration teaching aid for the heliosphere, the earth and the moon, and particularly relates to a fully simulated three-sphere instrument. Background technique [0002] At present, there are many kinds of domestic three-sphere products and patented technologies, but none of them can fully simulate and demonstrate the operation of the three-sphere of the sun, earth and moon. The education sector needs a more comprehensive three-sphere instrument to assist teaching, and the market needs higher technical performance. product upgrades. At present, the deficiencies in the three-ball instrument products and patented technologies mainly include: 1. They use the ecliptic coordinate system, among which large-scale three-ball instruments such as: the flying saucer three-ball instrument of Suzhou Yulong Science and Education Equipment Co., Ltd., Zhejiang Kangbei The luxurious three-sphere spheres of Science and Educati...

AI Technical Summary

Problems solved by technology

3. The stars and constellations are not drawn on the hemispherical transparent celestial sphere, and only the constellations of the zodiac are drawn on the fixed flat disc under the three spheres. When the earth revolves, it can only indicate that the heliosphere and the earth turn to a certain zodiac sign The orientation of a constellation, but it cannot indicate to a certain zodiac constellation on the celestial sphere, and the demonstration is not in place, such as: the multi-functional three-ball instrument of Nanjing Nanda Tianzun Electronics Co., Ltd., and the three-ball instrument of Wuhan Jindi Electronic Technology Co., Ltd. Instruments, etc. These products and technologies cannot demonstrate the seasonal changes of the starry sky and other astrological phenomena. Originally, the transparent celestial sphere painted with astrology images can be used for more functional demonstrations. Because it does not draw astrology images, the transparent celestial sphere is useless or has little effect

4. The moon can revolve but not rotate, let alone demonstrate that the moon always faces the earth when it rotates and revolves

5. The heliosphere can emit light but not rotate, and the demonstration function is lacking

6. The transmission mechanisms of the earth and the moon are exposed in the transparent celestial sphere, which affects the perception

7. There are few control functions, and it is not possible to control any one of the three balls to rotate or revolve independently, which is not convenient for a special demonstration

8. Only one kind of power supply can be used, and the conditions and environment of use are limited

In short, these products and patented technologies cannot completely simulate the three-ball operation due to their design concept and their own structure, or the degree of simulation is poor.
