Abstract

The utility model relates to a celestial globe used in teaching. The sphere is a transparent hollow sphere, the middle of the sphere is fixed with an earth model by a celestial axis, and both ends of the celestial axis are fixed at a scale semicircle ring. The earth model is movably connected with the horizontal circle by a short axis, and a plumb needle is fixed at the horizontal circle. The upper part of a pedestal is provided with a slot, and the scale semicircle ring is fixed in the slot of the pedestal by screws. The sphere is drawn with marks of an hour ring, a celestial equator, a latitude line, an ecliptic, a galactic equator and a celestial object.

Description

Celestial globe

The utility model is a kind of instruments used for education.

Lecturing astronomic knowledge in the teaching at present, do not have instruments used for education intuitively, generally all is the demonstration of drawing on blackboard, or replaces with terrestrial globe, brings difficulty to teaching.

The purpose of this utility model provides a kind of astronomical globe intuitively.

The purpose of this utility model is to realize like this.

The utility model is a kind of novel instruments used for education.Spheroid 1 is a transparent hollow spheroid, and ball center is fixed with earth model 3 by celestial axis 4, and the celestial axis two ends are fixed on the scale semicircular ring 6; Earth model is by minor axis 13 horizontal circle 2 that is rotationally connected; Vertical pin 5 is fixed on the horizontal circle; Base 7 top troughs of belt, the scale semicircular ring is fixed in the bottom tub by screw 8; Be decorated with the hour circle 9, celestial equator 10, declination 11, ecliptic 12 on the spheroid; Galactic equator 14; Ecliptic coordinate are right ascension 0 degree, declination 0 degree (first point of Aries 15), right ascension 90 degree, 23 27 minutes (summer solstices 16) of degree of declination and right ascension 180 degree, declination 0 degree (first point of Libra 17); Right ascension 270 degree, 27 fens coordinates of declination-23 degree on the ecliptic are firsts point of Capricornus 18; Galactic coordinates are right ascension 10 degree, declination 62 degree (being northern proximal pole point), right ascension 190 degree, declination-62 degree (being southern proximal pole point), right ascension 280 degree, declination 0 degree (being the galactic longitude starting point); Also have day body tag on the sphere because its spheroid is transparent, very visual pattern ground has shown celestial movement rule.Ecliptic is a sun orbit, and galactic equator is represented the milky way.The utility model can show variation throughout the year; The day row angular distance of the sun on celestial sphere; The constellation positions at every month place of the sun; Position on the ecliptic line at each solar term place; The being seen position of sun of different latitude on the earth; The operation of planet; The position of constellation etc.The utility model is simple in structure, is convenient to manufacture.Be the instruments used for education of systematic learning astronomic knowledge.
