Summary of the invention:
Too simple in order to overcome traditional three-globe instrument structure, accurately do not demonstrate out day,, the deficiency of month three ball kinematic relations, the utility model provides a kind of demonstrator according to the internationally recognized uranology data reproduction earth, moon operation, the true generation that embodies day and night change, four seasons formation, month phase change, solar eclipse and lunar eclipse intuitively, and 24 solar term residing diverse location of the earth when changing, thereby allow people understand the sun. the reason of the chronometer phenomenon formation that the earth, this three big celestial body of the moon are taken place after owing to the mutual change in location of motion.
The technical scheme that its technical matters that solves the utility model adopts is: the earth, the base of moon operation demonstrator is a transmission gear box, transmission gear box is by motor-driven, its output shaft is central shaft and the tubular shaft that is sleeved on differential rotation together, pivoted arm has been fixedly connected on the tubular shaft, end at pivoted arm, the mandrel and the gear that drive earth's axis rotation are housed, mandrel has had sleeve outward, fixing ground mounting cup and movable moon rotation seat are arranged on the empty sleeve, central shaft passes through gear, sprocket wheel, gear drive drives the terrestrial globe rotation on the earth's axis, when earth rotation 365.25 changes, pivoted arm on the tubular shaft rotates a circle around the sun, is exactly 1 year.Duplicate gear on the earth's axis drives the rotation of moon rotation seat by the level Four gear drive, and when earth rotation 29.53 was changeed, the moon that is fixed on the moon rotation seat rotated a week around the earth, is January.Described moon rotation seat surface and surface level have 5 ° 9 ' the pitch angle, the described earth's axis for the slanted angle on revolution orbit plane be 66 ° 30 '.Earth's axis movable set is on the gear shaft of ground mounting cup, the ground mounting cup is fixed on the sky sleeve, empty sleeve lower end is connected with sprocket wheel, links to each other with fixed chain wheels on the transmission gear box bearing seat by chain, thereby guarantees that the earth's axis is invariable in the sensing in space in the advancing of revolution of earth.The location rotating disk is equipped with in described transmission gear box output center axle upper end, can stop at an arbitrary position as required in presentation process, and can manually rotate demonstrator.
Described drive motor can be used its rotating speed of Frequency Converter Control, and the demonstrator travelling speed is stepless adjustable.
Be fixed with a sign dish on the described transmission gear box, the various chronometer phenomenons such as position of the variation of replacement, month elephant that can intuitively indicate four seasons earth during with 24 solar term variations.
The beneficial effects of the utility model are: the moving law that has reproduced the earth, the moon, ocular demonstration day,, month three ball kinematic relations and mutual alignment change the chronometer phenomenon that the back is taken place, can be used as the view on teaching and scientific research model, high-grade indoor appreciation ornament and public leisure place or square, popularize the propaganda astronomic knowledge, the utility model good looking appearance, the rotation precision height.
