Description
Technical field
The utility model relates to a kind of Multifunction terrestrial globe, belongs to the culture and education field of tool.
Background technology
Terrestrial globe is the instrument that shows the distributing position in earth geography situation, various countries and area.Existing terrestrial globe is simple spheroid, on spheroid, draw world map is arranged, function ratio is more single, simple geographical bitmap display effect can only be provided, show the situation of earth rotation, can not demonstrate out the geographical phenomenons such as " day alternates with night for Various Seasonal, change when local time and district, international date change " that the earth revolves around the sun and produced in rotation, and this partial content is one of main contents in the geography teaching in middle school, also is the difficult point place.Carry out teaching explanation with reference to traditional terrestrial globe, lack the demonstration effect of visual pattern, often have only dependence teacher's oral explanation and student's imagination to understand, make this part geographical knowledge in the process of learning aid, be subjected to considerable restraint like this, be unfavorable for student's profound understanding and grasp.
The utility model content
The purpose of this utility model is for a kind of Multifunction terrestrial globe is provided, owing on this terrestrial globe, be provided with a slidably dark transparent hemispherical cover body, its terrestrial globe that covers part promptly can be considered night hemisphere, can demonstrate out the earth phenomenon and day alternates with night phenomenon round the clock so visual in imagely, help the interpretation of terminator; Because in the time that hemispherical cover body subscript has been annotated night hemisphere, make geographical concept of time on this terrestrial globe, realize specializing and visualize, help to discern all parts of the world local time and international date to change this phenomenon; This terrestrial globe can demonstrate out in the four seasons alternation procedure two minutes two to the time earth on each hemisphere situation of length and variation, altitude of the sun and subsolar point position round the clock; This terrestrial globe is simple in structure, reasonable in design, simple operation, easy to carry, production cost is low, can be widely used in geographical teaching, the scientific research field.
In order to achieve the above object, the utility model is realized by following technological means.
The Multifunction terrestrial globe, it includes base, support bar, axle, spheroid, bracing frame, the hemispherical caps body portion, it is characterized in that: the upper end at base is provided with support bar, the upper end of support bar is provided with bracing frame, the middle inside of bracing frame is provided with chute, the bracing frame both ends are provided with axle, spheroid is fixed on the bracing frame by axle, be provided with hemispherical cover body between spheroid and the bracing frame, the outer middle side part of hemispherical cover body is provided with projection, projection and chute tabling are on hemispherical cover body, following two ends are respectively arranged with otch, and hemispherical cover body subscript is known the local time dividing line.
Described hemispherical cover body is divided into 12 five equilibriums by 13 dividing lines, the line when dividing line at hemispherical cover body middle part is labeled as local time 0/24, line (from West to East) line when line, local time 6 when line, local time 5 when line, local time 4 when line, local time 3 when line, local time 2 when being labeled as local time 1 successively from left to right during local time 0/24, line right-to-left during local time 0/24 (from the east orientation west) line when line, local time 18 when line, local time 19 when line, local time 20 when line, local time 21 when line, local time 22 when being labeled as local time 23 successively.
Described hemispherical cover body adopts dark transparent material to make.
The arc length of the otch of described hemispherical cover body upper/lower terminal equals the arc length of spheroid arctic point to the arc length of the Arctic Circle, Geophysical South Pole to the Antarctic Circle respectively.
Described spheroid inside can be provided with an illuminating lamp, is used for strengthening the demonstration effect.
Using method:
The spheroid of terrestrial globe is represented night by the hemisphere that hemispherical cover body covers, spheroid is positioned at the external hemisphere of hemispherical caps and represents daytime, and the boundary line of hemispherical cover body is the circle in morning and evening, and 6 o'clock lines are the line in morning, 18 o'clock lines can be demonstrated out earth phenomenon round the clock like this for the dusk line visual in imagely; Spheroid freely rotates in hemispherical cover body, can demonstrate the earth phenomenon that day alternates with night visually.
When the local time judged all over the world, as long as according to the longitude on the spheroid of correspondence, the time of reading on the corresponding hemispherical cover body gets final product.
When the international date is changed this phenomenon on the needs demonstration earth, can read the longitude on the spheroid of 0/24 o'clock line correspondence of hemispherical caps body, 0/24 o'clock line with hemispherical cover body is the boundary, and (right side) to the international date line (180 degree warp) on the spheroid is new one day eastwards, i.e. today; This warp westwards (left side) international date line (180 degree warp) to the spheroid be old one day, i.e. yesterday, can calculate the ratio on new on the earth, old two day date with this, thereby having solved the identification world date changes this difficult problem.
When the projection of spheroid is positioned at the middle part of chute, circle in morning and evening on the hemispherical cover body overlaps (as shown in Figure 1) with the coils of spheroid, at this moment, the whole world equinox, electrodeless main electrod phenomenon at night, sun direct projection equator, the solar noon sun height successively decreases to the two poles of the earth, north and south from the equator, can demonstrate out on two fen day earth each hemisphere length and variation, altitude of the sun and subsolar point position round the clock.
When hemispherical cover body upwards slides along chute by projection, hemispherical cover body covers to the north of the spheroid Arctic Circle, the Arctic Circle is all at hemisphere backlight (as shown in Figure 2), at this moment, the sun direct projection tropic of Capricorn (23 ° 26 ' S), the Northern Hemisphere enters polar night, and the solar noon sun height is successively decreased to the two poles of the earth, north and south by the tropic of Capricorn, Northern Hemisphere night is the longest, daytime is the shortest, all parts of the world situation of length and variation, altitude of the sun and subsolar point position round the clock in the time of can demonstrating Winter Solstice (Dec 22) like this.
When hemispherical cover body by projection along chute to lower slider, hemispherical cover body covers on the south the spheroid Antarctic Circle, the Antarctic Circle is all at hemisphere backlight, at this moment, the sun direct projection tropic of Cancer (23 ° 26 ' N), the Southern Hemisphere enters polar night, and the solar noon sun height is successively decreased to the two poles of the earth, north and south by the tropic of Cancer, the Southern Hemisphere night is the longest, daytime is the shortest, all parts of the world situation of length and variation, altitude of the sun and subsolar point position round the clock in the time of can demonstrating the Summer Solstice (June 22) like this.
The utility model mainly has following beneficial effect:
1, this terrestrial globe can be demonstrated out the earth phenomenon and day alternates with night phenomenon round the clock visual in imagely, helps the interpretation of terminator;
2, this terrestrial globe makes geographical concept of time realize specializing on this terrestrial globe and visualize, helps to discern all parts of the world local time and international date to change this phenomenon;
3, this terrestrial globe can demonstrate out in the four seasons alternation procedure two minutes two to the time earth on each hemisphere situation of length and variation, altitude of the sun and subsolar point position round the clock;
4, simple in structure, reasonable in design, the simple operation of this terrestrial globe, easy to carry, production cost is low, can be widely used in geographical teaching, the scientific research field.
