Description
The utility model relates to a kind of Astronomical clock, is clock and star globe combination are the device of one.
Star globe becomes important tool as the astronomical phenomena model already at teaching, astronomical fixation, the earth survey field.But present existing star globe will lean on computation of table lookup when celestial navigation is located, want armrest to move globe when determining celestial body coordinate or identification celestial body, and their precision and automaticity far can not satisfy the needs of current scientific technological advance.
Often need in practice a kind of can with in the universe between celestial body the characteristics of motion and temporal regularity simulate the instrument that reflects simultaneously.Technology that Chinese patent CN85205339U discloses a " day n-body simulation n timing clock ", it is to add terrestrial globe on common desk clock, lunar globe and universe galaxy simulation drawing cover, along with normally walking about of clock, the earth, the moon are just being demonstrated the spontaneous phenomenon of relative motion between celestial body by the hour hand axle transmission.This patented technology has following deficiency: one, in fact its celestial body model configuration part partly is separately independently with clock, and perfect inadequately on geometry, volume fails rationally to dwindle; Two, it is a spontaneous phenomenon of having simulated celestial bodies motion, but often need instrument can reproduce apparent motion (people the feel movement of heavenly bodies) rule of celestial body in using, therefore its inconvenient user, and it lack solar attachment, galaxy figure cover is fixed, the simulation astronomical phenomena are not exclusively true.
The purpose of this utility model is: overcome the deficiency of prior art, the Astronomical clock that a kind of apparent motion rule that can reflect celestial body, the sun, a certain actual astronomical phenomena of the moment of the moon again can instruction time is provided.
The utility model is realized like this: be made of celestial sphere, the earth, the sun, a crystal clock, a drive force source and celestial sphere, the moon and sun reduction gear, clock body support frame and pedestal separately, its design feature is: celestial sphere is a hyaloplasmic sphere housing, two ends are supported by the sky pole axis that links to each other with the clock body support frame, are marked with constellation and celestial equator, ecliptic and right ascension, latitude circle at its sphere; Have an opaque terrestrial globe housing to be fixed on day pole axis in the celestial sphere center, it is intracardiac that quartz clock movement is loaded on the earth, and the time display disc places earth front or pedestal front; The sun, the moon place in day global shell, with celestial sphere is to pass through reduction gear transmission separately by same power source, their speed brake setting in the ecliptic pole place of celestial sphere, they can rotate around the sky pole axis from the east orientation west synchronously with celestial sphere, reduction gear drives the sun and moves, drives the moon along the ecliptic track from West to East relative to celestial sphere and move from West to East relative to the sun simultaneously.
In such scheme as can be seen: clock is installed in the transparent celestial sphere, the two is combined as a whole; Simulating the relative motion of celestial body according to the apparent motion rule, allowing the earth fix and allow the sun, the moon and even other constellation rotate according to people's visual sense rule.Power source in the scheme can differ in size according to the astronomical phenomena model of different purposes and adopt motor or quartz clock movement respectively, small-sized Astronomical clock also can one quartz clock movement not only instruction time but also drive the astronomical phenomena model rotation.Reduction gear is to be made of driving gear set or worm gear, worm structure, and its ratio of gear designs according to astronomical phenomena rule or application need.Indicating mode as for clock can adopt pointer-type also can adopt digital display type, and it refers to that (showing) show that dish places the front or the pedestal front of the earth.
For such scheme, can adopt quartz analog clock movement, earth front can be opened a list index axis hole, pointer make with the ground sphere with the arcuation of curvature, time scale be marked on one be embedded in earth front, be on the annulus in the center of circle with the pointer axis hole.Like this, timing topology is blocked the pattern on the terrestrial globe hardly.
Can do following design for each several part reduction gear in the utility model in order to simulate between celestial body the characteristics of motion truly: make the power source transmission gear rotate a week in per 24 hours, and universe starry sky is relative to per 24 hours " rotation " 366/365 weeks of the earth, and therefore getting celestial sphere is 365/366 with respect to the ratio of gear that power source rotates; " change " week because the moon and be around the earth 29.5 round the clock (moon month) promptly be equivalent to power source and changeed for 29.5 weeks, therefore getting the moon is 29.5 with respect to the ratio of gear of power source; The sun " change " around the earth week be 365.24 round the clock (calendar year) promptly be equivalent to power source and changeed for 365.24 weeks, therefore getting the sun is 365.24 with respect to the ratio of gear of power source.On this programme basis, can indicate 1 year date lattice of the Gregorian calendar on the ecliptic with the celestial sphere surface, along with the moving of solar attachment, just can indicate the Gregorian calendar date on the same day like this; Also can be on the same plane of ecliptic be with the solar attachment eventually, initial point adorns an annulus that is changeed by the solar attachment band, this ring is divided into 29.5 lattices and corresponding indicates per medio of the lunar calendar thereon, because the moon is to rotate a week from West to East relative to the sun in per 29.5 days in apparent motion, so, just can indicate the lunar date on the same day along with moving of lunar globe.
The utility model has the advantages that:
1. can be used as the timing commodity, have practicality, decoration and manufacturability characteristics in one.
2. can be used as the specific purpose tool of astronomical fixation, because it organically is combined as a whole motion between the celestial body of universe with temporal regularity, and can high precision, full-automatic apparent motion rule between the true reappearance celestial body, therefore can replace existing various star globe or astronomic clock fully and come into operation.
3. can be made into teaching aid, as long as its reduction gear is adjusted in proportion, just can on the classroom, show the celestial body apparent motion scene of universe required time or a year.
4. can be installed in various public places as the tendentious striking mechanism of a kind of knowledge.
