Abstract
The invention provides a magnetic-repulsion day-and-night globe structurally comprising an inner layer and an outer layer, wherein, a black and white background sphere is positioned in the inner layer; a transparent drawing sphere is positioned in the outer layer; the geographical map of the earth is produced on the surface of the transparent drawing sphere; the invention is characterized in that a magnet is mounted inside the black and white background sphere, and another magnet which is arranged outside the transparent drawing sphere drives the black and white background sphere to rotate in a non-contact manner by the interaction force generated by the two magnets; and the time scales of the local time corresponding to the longitudes in one day are marked on the outer surface of the black and white background sphere. The simple method of the invention solves the problem that the day-and-night state of the earth is difficult to be demonstrated by the ordinary globe, provides convenience for operations and expands the teaching functions of the globe, so that the day-and-night formation of the earth can be easily understood; and the globe of the invention constitutes a fully-featured and scientifically-significant globe for teaching and interior decoration.
Description
Technical field
The present invention relates to a kind of terrestrial globe, particularly relate to a kind of magnetic-repulsion day-and-night globe.
Background technology originally
Terrestrial globe is the instrument that shows earth geography situation, various countries and regional position distribution, often uses in teaching, scientific research, particularly the instruments used for education that must use in the teaching of middle and primary schools' Science Curriculum.Existing terrestrial globe is all fairly simple, and it comprises central rotating shaft fixing on base, support and the support, can simulate the spheroid of earth rotation on the central rotating shaft, by the geographic distribution drafting each countries and regions is arranged on the spheroid.Yet the earth is also done the revolution of 1 year one-period around the sun, and this has just formed spring, summer, autumn and winter that we experience year after year and the sunrise sunset of every day.Present terrestrial globe can reflect the rotation of the earth, but can not reflect earth rotation on the terrestrial globe time, owing to and the sun between the The diurnal distribution situation that forms of relation, be difficult for making the student to understand the earth and form the state that changes round the clock.Attempt to want on terrestrial globe, to embody the terrestrial globe of state round the clock and also have at present, yet all realize that by the interior mode such as light source of establishing effect is unsatisfactory.
Summary of the invention
The present invention provides a kind of magnetic-repulsion day-and-night globe for the state round the clock that solves in real time, simulated solar illumination on the spot forms the earth, is used to understand the situation round the clock of various places.
The present invention realizes by following measure: this magnetic-repulsion day-and-night globe comprises base, support, can be fixed on the disloyalty rotating shaft at support two ends, the black and white background spheroid that can rotate around positive heart rotating shaft, the transparent print face ball that can rotate around oblique heart rotating shaft; Support is installed on the base, and the disloyalty rotating shaft is installed in the support two ends, and black and white background spheroid is installed in the positive heart rotating shaft of disloyalty rotating shaft, on be coated with black and white half and half color, be in internal layer; The transparent print face ball is installed in the oblique heart rotating shaft of disloyalty rotating shaft, on the geographical pattern of the transparent earth is arranged, be in skin.It is characterized in that a magnet is installed in black and white background spheroid inside, another magnet rotates by the discontiguous drive black and white of the interaction force background spheroid between magnet outside the transparent print face ball.
Described black and white background outer surface of spheroid is marked with the pairing local time time scale of each longitude in a day.
Because the transparent print face ball and on geographical pattern be transparent, want the backrest scape to set off out pattern, the black and white background spheroid of the inside can set off out the black and white effect, transparent print face ball pattern under the white background is analysed bright clearly, representative is in the state on daytime, and the transparent print face ball pattern under the black background is intensely dark, represents the state at night, thereby show the state round the clock of the earth, and detect residing local time according to the time scale on the black and white background spheroid.Black and white background spheroid can rotate as required, and the user can forward black and white background spheroid to destination locations by outer magnet, thereby embody in good time earth state according to the imagination position relation of the earth and the sun.
The present invention has solved the state round the clock that common terrestrial globe is difficult for representing the earth with easy method, simple in structure, easy to operate, enlarged the instructional function of terrestrial globe, being easy to people and grasping the knowledge that the earth forms round the clock, is teaching and the interior decoration terrestrial globe that a kind of function is comprehensive more, have more scientific meaning.

Embodiment
The present invention will be further described below in conjunction with example and accompanying drawing:
As shown in Figure 1, be apparatus of the present invention structural representation.This black and white globe is made up of base 1, support 2, disloyalty rotating shaft 3, transparent print face ball 4, black and white background spheroid 5, support 2 is installed on the base 1, disloyalty rotating shaft 3 is installed on 21,22 corresponding apertures of support two ends by screw, black and white background spheroid 5 is installed in the positive heart rotating shaft of disloyalty rotating shaft 3, a magnet 56 is installed in the black and white background spheroid 5, magnet 57 can not promote black and white background spheroid 5 and rotates by not contacting with the effect of the magnetic force of magnet 56, and transparent print face ball 4 is installed in the oblique heart rotating shaft of disloyalty rotating shaft 3.
As shown in Figure 2, examples of implementation for disloyalty rotating shaft 3 of the present invention, disloyalty rotating shaft 3 has changed common terrestrial globe and has had only an axial central rotating shaft structure, has become to have two axial rotating shafts, that is: with the vertical positive heart rotating shaft and the oblique heart rotating shaft that becomes 66.5 degree angles with surface level of surface level.Be provided with the protruding 33,34 of location black and white background spheroid 5 above the disloyalty rotating shaft 3, location transparent print face ball 4 protruding 35,36 is used for this is fixed on hole 31,32 on the support.During installation, with on 21,22 pairs in the hole on hole in the disloyalty rotating shaft 3 31,32 and the support, load onto corresponding screw or latch, disloyalty rotating shaft 3 just can be fixed on the support 2.Disloyalty rotating shaft 3 can also can be adopted the method for sectional making according to the arts demand of making by once-forming, is formed by connecting after the branch plurality of sections is carried out, as long as enough firmly again.
