CN2135178Y - Demonstrator for moving of the earth or the moon - Google Patents

Abstract

The utility model relates to a demonstrator for the moving of the earth or the moon, using a light source with a spherical surface as the sun and being driven by a motor or a clock. The utility model is characterized in that the demonstrator simulates actual motions according to the relation of the visual angle and the speed ratio and can demonstrate natural phenomena, such as time difference, month difference and year difference, the sunrise and the sunset, the round and the non-round lunar images, the solar and the lunar eclipses, the changes of the four seasons, etc. The utility model has the advantages that the revolution and the rotation has accurate moving speed ratio; the demonstrator as a scientific instrument driven by the clock can be synchronous with the actual motions, and the error of each hundred years is less than one day; the demonstrator as a teaching instrument driven by the motor can demonstrate with a fast and slow speeds; the demonstrator matched with beautiful pictures printed with Monkey Sun and Goddess in the moon can be a decoration, an intelligent toy and a large-sized game device.

Description

Demonstrator for moving of the earth or the moon

The utility model is a kind of instrument of demonstrating ground month operation.

The natural science of large, medium and small, geography class, astrophysics class is being told about when moving relevant spontaneous phenomenon and length velocity relation with day ground, Jing Mi apparatus for demonstrating for want of, student's indigestion and imagination.Several structures of propositions such as patent announcement CN2100008U.CN2100007U also can only be demonstrated the part spontaneous phenomenon, and the speed ratio relation is inaccurate.

The utility model purpose is to provide a kind of simple in structure, and speed ratio is month running instrument accurately, comprehensive simulated real motion, demonstration and the ground month relevant a series of spontaneous phenomenons of operation realistically.

Principal character of the present utility model is to serve as the sun with the sphere light source, and precision interval clock or speed control motor-driven gear link mechanism are finished the ground operation of the moon.

Center beam barrel (3) is fixed on the center that the edge indicates the chassis (13) of zodiacal circle star chart, and an end of long-armed (1) is enclosed within the bottom of beam barrel (3), can rotate around (3), and the other end is equipped with gear drive and earth-moon apparatus; Clock or motor (5) are controlled the gear coaxial with (10) (11) and (23) by sprocket wheel (4) and (10) that chain connects, it was rotated around precession of the earth axle (24) counterclockwise with the constant cycle, gear (23) makes terrestrial globe rotation on the earth's axis (27) by gear (25), whenever circling with respect to long-armed (1) is a solar day, whenever circling in relative chassis is a sidereal day, can observe and calculate the time difference; Gear (11) then rotates counterclockwise around 6 moon hollow shafts (22) of spending that tilt by gear (17) and (20), whenever circling with respect to long-armed (1) is a lunar month lunation, whenever circling in relative chassis is a sidereal month, round scarce variation of demonstration month picture under the irradiation of sphere light source (12), and press predetermined period, the of that month heart, the earth's core, a day heart eclipse will occur when being positioned at a straight line, and lunar globe is fixed on the axle (28), make it maintain the fact that one side is carried the earth forever; Clockwise rotate by gear (8) (7) (9) (6) difference driven wheel (18) and (16) with the gear (19) of gear (21) with wheel, make moon hollow shaft (22) precession that links with gear (18), can observe and calculate the cycle of the displacement and day lunar eclipse of yellowish-white road lifting intersection point; Gear (16) makes precession of the earth axle (24) drive be installed in earth's axis (27) the slowly precession clockwise of upper end rake; Axle (24) bottom sprocket wheel (15) is connected by chain with beam barrel (3) bottom fixed chain wheels (2), force long-armed (1) around beam barrel (3) revolution counterclockwise, whenever circle long-armed (1), the projection of earth's axis (27) on chassis (13) has the central lines with long-armed (1) twice, the expression Summer Solstice and Winter Solstice, the earth's core is with the orbital motion of ellipse garden, the aphelion is the Summer Solstice, perihelion is Winter Solstice, have twice and vertically represent the Spring Equinox and the Autumnal Equinox, sprocket wheel (15) edge 24 solar term scales of institute's target are used for accurately indicating seasonal variations, if the Spring Equinox, scale was day in the Spring Equinox over against long-armed (1) end pointer (14), corresponding point on the zodiacal circle of chassis (13) are the first point of Aries at this moment, because of the slow precession of axle (24), will slowly move on zodiacal circle the first point of Aries with the demonstration precession phenomenon, whenever circling in long-armed (1) relative chassis is a sidereal year, whenever circling the first point of Aries relatively is a tropic year, the axis of rotation (27), (28) also be provided with on and realize sky and tour the heavens, The Goddess Chang'e flew to the moon ornament.

Rotating speed by control sprocket wheel (10) can be demonstrated at a slow speed soon, and accurately control (10) made circle just in its per 24 hours, and then the utility model will be synchronous less than one day precision and real motion with every century-old error.

By above feature, the utlity model has and truly demonstrate effect intuitively, can make teaching appliance, ornament, puzzle and large-scale Game device.

Accompanying drawing is the utility model structural drawing.
