Teaching and science popularization celestial globe

Abstract

A teaching and science popularization celestial globe of the invention relates to the fields of education technology, astronomy and science, school education and teaching of earth and space science, urban and rural science popularization, and celestial space research, and aims to solve the problem that astronomy and geography teaching in universities, middle schools and primary schools lacks planet space teaching instruments as well as design schemes and technologies for celestial globe manufacturing and using. The teaching and science popularization celestial globe is composed of a four-color map globe (1), a transparent celestial globe (2), an equatorial longitude large disc (3), a double-lug bow-shaped latitude half disc (4), a celestial axis (5), two metal circular-hole plain cushions (6), two rubber sleeves (7), and a base (8). The teaching and science popularization celestial globe is used for demonstrating the Tropic of Cancer and the Tropic of Capricorn of a globe, the celestial equator, the ecliptic, the moon's path, the celestial equator dividing line and the longitude and latitude space model on a celestial globe, the 24 solar terms in geography, 88 constellations in the starry sky, the approximate locations of stars and planets of 28 constellations of Chinese asterism, and teaching and science popularization of natural phenomena in knowledge of the 88 constellations in astronomy and earth and space sciences.

Description

technical field [0001] The patent of the present invention relates to the field of astronomy knowledge teaching in universities, middle schools, and primary schools, and popularizes scientific knowledge to the general public in cities and rural areas, and especially involves guiding 1.3 billion people in our country to understand the 88 constellations in the sky discovered by ancient Greek astronomers and ancient Chinese astronomy. It is a kind of teaching and popular science celestial globe in the field of astronomy, earth, starry sky teaching and research, which discovers the astronomical scientific phenomena of the approximate positions of 28 stars in the sky, the law of natural science celestial body motion, and astronomy, the earth, and starry sky teaching and research. Background technique [0002] Over the past 35 years of reform and opening up, due to the infiltration and introduction of Western culture, among the vast number of students in the urban and rural areas o...

AI Technical Summary

Problems solved by technology

Making, testing and using the "Transparent Four-color Longitude and Latitude Celestial Globe", it was found that drilling 3 to 4 small holes on the spherical shell of the southern hemisphere and the large disk of equatorial longitude was too troublesome. Due to the limited thickness of the spherical shell of the globe, drilling It is easy to break through the spherical shell during the drilling process and damage the southern hemisphere, and after fixing the equatorial longitude disc on the southern hemisphere with small screws, the screws will loosen due to sudden cooling and heat changes in hot and cold weather, which will affect the demonstration effect

When the celestial axis is rotated, the latitude semi-disc is easily separated from the celestial axis and gets stuck in the celestial shell, which affects the celestial axis to drive the globe and the equatorial longitude disk to rotate. In particular, the celestial axis is made of a stainless steel cylinder, and drilling is extremely difficult. , whether it is to fix the latitude semi-disc on the celestial axis by welding metal pillars, or to drill holes on the latitude semi-disc and the celestial axis, and fix the latitude semi-disc to the celestial axis with screws, it is easy The latitude half-disk falls off from the position fixed on the celestial axis due to the gradual loosening of the screws, which affects the service life, product quality and demonstration effect of the transparent four-color latitude and longitude celestial sphere
