Abstract
The utility model terrestrial globe in morning and evening, mainly comprise base, rotating shaft, terrestrial globe, hemisphere and half circle body, it is characterized in that, rotating shaft is fixed on base, rotating shaft is through the two poles of the earth, north and south of terrestrial globe, the two ends of rotating shaft are passed and are fixed wtih the holder of two panels sphere, and hemisphere and half circle body in sphere jacking, and hemisphere and half circle body link into an integrated entity.The upper and lower symmetric design of described hemisphere has U-shaped breach, and half circle body two ends are designed with U-shaped connector and link into an integrated entity, and U-shaped breach is identical with U-shaped connector length scale and equal or the spherical radius of north and south polar circle slightly larger than terrestrial globe.Described hemisphere is the hemispherical shell of painted black.Be connected with billet in the middle of half described circle body, billet is vertical with terrestrial globe sphere, and described billet paints redness.Described rotating shaft becomes 66 ° of 34 ' angle with base plane.
Description
Technical field
The present invention relates to a kind of teaching aid, particularly relate to the terrestrial globe in morning and evening demonstrating day-night change in a kind of geographical teaching.
Background technology
Terrestrial globe is the important teaching aid of middle and primary schools' geography course, utilizes existing terrestrial globe all fairly simple as teaching aid, generally can only show the director's thing distribution of earth Shangdi, revolutions in analog, but can not represent the geographical phenomenons such as day-night change.Chinese patent CN200910126570.4 introduces a kind of terrestrial globe that can show round the clock, by the black and white background spheroid display day and night change change of rotating, but it can not show various places the diurnal distribution, the change of 1 year day-night length and subsolar point and moves Changing Pattern.In teaching, particularly Senior Geography Teaching, subsolar point moves that to enclose mobile Changing Pattern with morning and evening comparatively abstract, student not easily understands, be a difficult point of Senior Geography Teaching, by existing globe teaching aid, it is clear that teacher is often difficult to demonstrate explanation to student.
Summary of the invention
The object of the invention is to solve in geographical teaching, utilize existing terrestrial globe teaching aid, be difficult to demonstration explanation and know that subsolar point moves the problem of enclosing mobile variation phenomenon with morning and evening, there is provided a kind of structure simple, demonstration is convenient, intuitively can show the terrestrial globe of earth day-night change and subsolar point movement law.
The present invention is realized by following measures: morning and evening of the present invention terrestrial globe, mainly comprise base, rotating shaft, terrestrial globe, hemisphere and half circle body, it is characterized in that, rotating shaft is fixed on base, rotating shaft is through the two poles of the earth, north and south of terrestrial globe, the two ends of rotating shaft are passed and are fixed wtih the holder of two panels sphere, and hemisphere and half circle body in sphere jacking, and hemisphere and half circle body link into an integrated entity.
The upper and lower symmetric design of described hemisphere has U-shaped breach, and half circle body two ends are designed with U-shaped connector and link into an integrated entity, and U-shaped breach is identical with U-shaped connector length scale and equal or the spherical radius of north and south polar circle slightly larger than terrestrial globe.
Described hemisphere is the hemispherical shell of painted black.
Be connected with billet in the middle of half described circle body, billet is vertical with terrestrial globe sphere, and described billet paints redness.
Described rotating shaft becomes 66 ° of 34 ' angle with base plane.
Morning and evening of the present invention terrestrial globe, terrestrial globe can tilt to rotate around the axis, and can work as commonly globe.Hemisphere and half circle body can move around around rotating shaft, and because U-shaped breach and U-shaped connector length scale are the spherical radius of the north and south polar circle of terrestrial globe, the billet in the middle of half circle body can move between the north and south tropic on terrestrial globe.
Dark hemisphere body shelters from half terrestrial globe, can demonstrate earth the diurnal distribution; Dark hemisphere body moves around around rotating shaft in breach, can demonstrate the earth hemisphere changes in distribution of a year round the clock, day-night length change in a year; Half billet in the middle of circle body can move between the north and south tropic on terrestrial globe, can demonstrate the movement law of subsolar point on the earth, also can embody subsolar point and morning and evening coil the inner link of mobile change.
The easy method of the present invention solves day-night change and the subsolar point mobile phenomenon at the earth's surface that commonly globe not easily represents the earth, its structure is simple, make easily, easy to operate, expand the instructional function of terrestrial globe, be easy to the knowledge of the movement law of subsolar point on student's understand and master earth day-night change and the earth.
Accompanying drawing explanation
Fig. 1 is the structural representation of terrestrial globe in morning and evening of the present invention.
embodiment:
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, morning and evening of the present invention terrestrial globe, mainly comprise base 1, rotating shaft 2, terrestrial globe 3, hemisphere 5 and half circle body 6, rotating shaft 2 is arranged on base 1, rotating shaft 2 becomes 66 ° of 34 ' angle with base 1 plane, rotating shaft 2 is through the two poles of the earth, north and south of terrestrial globe 3, and the two ends of rotating shaft 2 are passed and are fixed wtih two panels sphere holder 4, and sphere holder 4 heads on hemisphere 5 and half circle body 6.
Described hemisphere 5 is the hemispherical shell of painted black, and its upper and lower symmetric design has U-shaped breach, and half circle body 6 two ends are designed with U-shaped connector and link into an integrated entity, and U-shaped breach and U-shaped connector length are the spherical radius of the north and south polar circle of terrestrial globe 3.
Be connected with billet 7 in the middle of half described circle body 6, billet 7 is vertical with terrestrial globe 3 sphere, and described billet 7 paints redness.
When morning and evening of the present invention, terrestrial globe used, terrestrial globe 3 can tilt and 2 rotate around the shaft; Along with hemisphere 5 and half circle body 6 move around in rotating shaft 2, hemisphere 5 is made to shelter from the hemispherical portion of terrestrial globe 3, mobile change on the north and south polar circle of terrestrial globe 3, the billet 7 in the middle of half circle body 6 moves around change on the north and south tropic of terrestrial globe 3.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
