Abstract

The utility model relates to an earth season demonstration apparatus, and the demonstration apparatus mainly consists of a sun model, an earth model, and a moon model. A rotating arm on a supporting frame is provided with the earth model which can spin, a rotating disk on the rotating arm is fixed and provided with the moon model which can revolve around the earth model through an arc rod, the earth model is respectively provided with electric light sources in four colors of red, yellow, blue, and green on the southern hemisphere and the northern hemisphere, a subround four season display board is arranged on the supporting frame under the rotating arm, and the on and off of the electric light sources of the earth model is controlled by a switch. Through four season display rings, and the illumination changes of different colors of the four seasons of the northern hemisphere and the southern hemisphere of the earth model, the four season changes of the earth revolving around the sun for a year are visually demonstrated, thereby helping students understand the regulation and the formation reason of the four season changes of the southern hemisphere and the northern hemisphere in a year.

Description

Earth four seasons demonstrator

Affiliated technical field

The utility model relates to a kind of earth demonstrator.

Background technology

At present, the three-globe instrument that school uses, the relative motion of the demonstration earth, the moon, the sun, since directly perceived inadequately to the change demonstration that the earth moves round the sun throughout the year, be unfavorable for that the student understands the reason that forms throughout the year.

Summary of the invention

The purpose of this utility model provides a kind of earth four seasons demonstrator, is used for ocular demonstration the earth moves round the sun track, and earth change in location throughout the year, helps the student to understand the reason that forms throughout the year.

The technical scheme that the utility model technical solution problem is taked is: the main solar model of earth four seasons demonstrator, earth model, moon model are formed.In red solar model that has electric light source of support design, solar model has one perpendicular to the support and the pivoted arm that can rotate around support on the support, pivoted arm is provided with the One Earth One Family model, the rotating shaft of earth model and the angle of pivoted arm are 66.5 degree angles, earth model is rotation around the shaft, rotating shaft is provided with rotating disk movingly, rotating disk is fixed with a moon model by a bow, moon model can rotate around earth model, the plane of rotating disk and the angle of pivoted arm are 5 degree, the central horizontal face of earth model and the central horizontal face of solar model are on same surface level, earth model is respectively equipped with redness respectively at the Southern Hemisphere and the Northern Hemisphere, yellow, blue, the electric light source of green four kinds of colors, redness is represented the Summer Solstice, yellow is represented the Autumnal Equinox, blueness is represented Winter Solstice, and green is represented the Spring Equinox.Rotund four seasons display board is arranged on the support under the pivoted arm, display board has two rotund four seasons to show ring, article one, the four seasons that are the Northern Hemisphere show ring, by etc. equal green, redness, yellow, blue four sections camber lines be linked to be according to green, red, yellow, blue order, show the seasonal variations in Northern Hemisphere spring, summer, autumn, winter respectively; Another is four seasons in the Southern Hemisphere to show ring, by etc. equal yellow, blueness, green, red four sections camber lines be linked to be according to yellow, blue, green, red order, show the seasonal variations in the Southern Hemisphere autumn, winter, spring, summer respectively; Pivoted arm is provided with control enclosure, and control enclosure is provided with manual or automatic switch, with the switch control earth model Northern Hemisphere and the Southern Hemisphere green, redness, yellow, blue electric light source puts out and go out.During use, with hand spherical model movably, when earth model forwards green (or yellow) four seasons to when showing ring position, by switch, connect the electric light source of Northern Hemisphere green, and the electric light source of connecting the Southern Hemisphere yellow, this moment, the Northern Hemisphere showed green, the Southern Hemisphere shows yellow, and the expression Northern Hemisphere forwards spring to, and the Southern Hemisphere forwards autumn to simultaneously; Earth model rotates 90 and spends red (or blue) four seasons when showing ring position, pass through switch, connect the electric light source of Northern Hemisphere redness, and the electric light source of connecting the Southern Hemisphere blueness, this moment, the Northern Hemisphere showed red, the Southern Hemisphere shows blue, and the expression Northern Hemisphere forwards summer to, and the Southern Hemisphere forwards winter to simultaneously; Earth model rotates 90 again and spends yellow (or green) four seasons when showing ring position, pass through switch, connect the electric light source of Northern Hemisphere yellow, and the electric light source of connecting the Southern Hemisphere green, this moment, the Northern Hemisphere showed yellow, the Southern Hemisphere shows green, and the expression Northern Hemisphere forwards autumn to, and the Southern Hemisphere forwards spring to simultaneously; Earth model rotates 90 again and spends blue (or red) four seasons when showing ring position, pass through switch, connect the electric light source of Northern Hemisphere blueness, and the electric light source of connecting the Southern Hemisphere redness, this moment, the Northern Hemisphere showed blue, the Southern Hemisphere shows red, and the expression Northern Hemisphere forwards winter to, and the Southern Hemisphere forwards summer to simultaneously.

The beneficial effects of the utility model are: show the variation that ring and the earth model Northern Hemisphere, the Southern Hemisphere luminous variation of four seasons different colours comes ocular demonstration the earth moves round the sun throughout the year by the four seasons, help the student to understand the rule that southern hemisphere and northern hemisphere changes throughout the year and the reason of formation.
