Abstract
The present invention relates to a simulated terrestrial globe with an equatorial coordinate system, which comprises an earth model composed of two concentric spheres: one internal sphere and one external sphere, wherein the internal sphere rotates around the axis of the earth, the external sphere is a combination of two bicolor hemispheres and rotates around the dawn-and-dusk axis, and cursors on the surface of the external sphere are connected with a revolution driving arm; two hemispheres of a red sun model are connected by an orbital plate forming an intersection angle of 66.5 DEG with a pillar, two actuating units are respectively arranged in the center of the internal sphere and the center of the orbital plate. The present invention can simulate and demonstrate natural phenomena, such as the rotation and the revolution of the earth around the sun, the existence of a natural intersection angle between an ecliptic plane and an equatorial plane, spring equinox and autumn equinox, the perpendicular incidence and the oblique fire of sunlight, the division of five natural zones, etc., in the equatorial coordinate; besides, the present invention has the advantages of visual images and preferable effect of demonstration and teaching.
Description
Technical field
The present invention relates to the science and education instrument, a kind of specifically EquatorCoordinateSystem simulation loxocosm.
Background technology
The earth is around day operation, caused length round the clock changes, the four seasons form, sunlight point of vertical situation of movement, the division of five bands ... etc. spontaneous phenomenon, no matter teach in word or the Popular Science Education at geography, all be difficult to language, wall chart, general teaching aid etc. is told about clear, demonstrate the instrument of earth operation exactly, cooperate explanation, also owing to present these instruments also come with some shortcomings as three-globe instrument, loxocosm etc., fast again as the too little rotating speed of the terrestrial globe in the three-globe instrument, do not see Chu during demonstration; Earth operation influences overall image by big base support, and some relevant knowledge (as ecliptic obliquity, the direct projection of light, oblique fire ...) intuitive is strong etc. when telling about.
At present, at the earth on this problem of day operation, no matter be textbook, popular science books, wall chart, science and education instrument, and even terrestrial globe etc. all belong to the EclipticCoordinateSystem category, that is to say that they all are angle from EclipticCoordinateSystem rule and the caused various spontaneous phenomenon thereof of analytical table terrain ball around day operation that get on.
Summary of the invention
At above-mentioned situation, the object of the present invention is to provide a kind of brand-new EquatorCoordinateSystem simulation loxocosm, it be in a kind of coordinate under the line the analog demenstration earth around the instrument of day operation, can demonstrate the earth around day rotation and revolution, the existence of the ecliptic plane and the equatorial plane nature angle of cut, the Spring Equinox, the Autumnal Equinox, sunlight direct projection, oblique fire situation, spontaneous phenomenons such as five band divisions, visual in image, demonstration, teaching efficiency are preferably arranged.
The object of the present invention is achieved like this:
A kind of EquatorCoordinateSystem simulation loxocosm, it is that the analog demenstration earth is around the instrument of day operation in the coordinate system under the line, it is characterized in that: this instrument comprises
An earth model that constitutes by inside and outside two-layer homocentric ball, endosphere is around earth's axis rotation, press the equatorial coordinates operation, adorning power, the gearing of controlling rotation in the ball, ectosphere is hollow double-colored hemisphere assembly, and its water white transparency hemisphere is positioned at the sunside, light grey transparent hemisphere is positioned at the back of the body day face, ectosphere is pressed the operation of ecliptic coordinate around axle rotation in morning and evening, and its lip-deep cursor is connected with the revolution transmission arm;
A solar model that is made of two red hemisphere is equipped with the track plate with the pillar oblique between these two hemisphere, whole solar model by base, shore supports;
Described track plate ovalize, its sign that indicates 24 solar term all around, it is positioned at the actuating unit that sun ball middle body is equipped with the control revolution.
Purpose of the present invention can also realize by following measure:
Its middle orbit plate is made with yellow organic glass, and its major axis is 520cm, and its minor axis is 480cm, is similar elliptical shape, and this track plate is tiltedly worn the centre of sphere of solar model and is the angle of cut of α=66.5 ° with the instrument pillar.
The power, the gearing that wherein drive rotation and revolution comprise motor, button, switch, reduction gearing revolution transmission arm, are contained in respectively in earth model and the solar model.
Wherein earth model moves in the coordinate under the line, and this earth model center of gravity is positioned at lower position and can utilizes action of gravity to make the earth's axis keep up north and down south perpendicular to the ground.
The present invention has following actively useful effect:
1, the power of spherical model 13 rotations drivingly and revolution, gearing is contained in respectively in earth model 13 and the solar model 4, track plate 8 (being ecliptic plane) is made with yellow organic glass, be installed in two hemisphere 4A of solar model 4, in the middle of the 4B, the cursor 10 of earth model is connected with revolution transmission arm 7, earth model 13 pictures move around solar model 4 like unsettled when demonstrating like this, image is really true to life, described cursor 10 can be three vertical bars as shown in Figure 1, also can be circle cover (accompanying drawing does not show), this cursor shines the sunbeam of the earth except that representing, and plays bracing frame vacant lot globe.
2, ecliptic obliquity, the ecliptic plane (being orbital plane) and the equatorial plane (equatorial circumference) intersect 23.5 ° of angles, more abstract during this problem explanation, because the track plate (being ecliptic plane) of this instrument is made with yellow organic glass, equatorial circumference (being the equatorial plane) is near the operation of track plate, so no matter earth model 13 where run to can direct viewing to the existence of ecliptic obliquity, very directly perceived.
3, the Spring Equinox, the Autumnal Equinox, this instrument can direct viewing to being in simultaneously on the yellow red intersection when earth model 13 and solar model 4 (strictness say so their centre of sphere), at this moment cursor 10 refers to go up under the line, no matter the Northern Hemisphere or the Southern Hemisphere round the clock length equate, if earth model 13 is in from south orientation north (liter) operation, at this moment is the Autumnal Equinox, otherwise, if earth model 13 is in from north orientation south (falling) operation, at this moment is the Spring Equinox.
4, the elliptical orbit plate 8, and earth orbit is oval, and ellipticity is very little, sub-circular is wanted additional explanation when so not only explaining, and on science, also cause misunderstanding easily, the equatorial coordinates loxocosm is as instruments used for education, in order to give top priority to what is the most important, deepen understanding, not violating under the scientific prerequisite, track plate 8 is made overweening ellipse, major axis 520cm, minor axis 480cm, come into plain view to the people, staying earth 's orbit is oval deep impression.
5. this instrument is provided with organic glass system, the expression of thickness unanimity is mapped to the cursor 10 of earth model diverse location, be used for observing, analyzing because the geographic position difference is accepted the different situations of solar heat energy, make original abstract sunlight direct projection, oblique fire, the ground that is difficult for the clarifying situation of being heated, directly perceived, the imagerys of spontaneous phenomenon such as five band divisions are beneficial to explanation and acceptance.
6. the earth's axis of this instrument is upright (being up north and down south), and the map on the terrestrial globe is consistent with map direction on the general wall chart.
