Abstract

The invention relates to a full-simulating sun-moon-earth instrument which comprises a sun rotation and lighting device, an earth rotation device, an earth revolution device, a moon rotation device, a moon revolution device, an earth-moon rising and dropping device, and speed regulating and control circuits, wherein the earth-moon rising and dropping device is arranged at the external end of a long arm of the earth revolution device; the earth rotation device, the moon revolution device, the moon rotation device and the moon rising and dropping device are arranged on the earth-moon rising and dropping device; all the devices above run around the sun at the centre; and the full-simulating sun-moon-earth instrument is characterized in that the earth synchronously rises and drops during performing the revolution around the sun, and the moon synchronously rises and drops during performing the revolution around the earth; with the adoption of the composite motion, the due intersect angles can be formed between an earth revolution orbit plane and the sun equator plane and between a moon revolution orbit plane and the earth equator plane; the speed ratio of the sun to the moon to the earth under the rotation and the revolution can be similar to the actual speed ratio by carrying out electronic speed regulating; and the star image drawn on a transparent celestial sphere is similar to the actual star image, therefore, the running of the three balls can be comprehensively and really displayed in a three-dimensional and vivid way, and the running rules and resulting astronomical phenomena and the natural phenomena can be popularly and quickly indicated; and the practical significance is brought to popularization of the 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...
