Abstract
The utility model relates to a time and space globe which comprises a globe body, a globe axis, a rotary handle, an outer rotary handle, a base, a morning and dusk ring, a time graduated loop and a viewing position point of direct solar radiation, wherein, the morning and dusk ring is a fine circular loop and is arranged on the outer rotary handle; the bottom of the outer rotary handle is provided with a reverse triangular mark which is on the same plane as the morning and dusk ring; the surface of the base is provided with a month graduated loop; the time graduated loop is an oblate loop with the size which is approximate to the size of the morning and dusk ring, and time graduations of twenty-four hours are marked on the time graduated loop which is arranged on the morning and dusk ring. The utility model has the advantages of concise and practical structure and many functions, and can visually demonstrate various natural phenomena, such as the revolution of the earth, the rotation of the earth, the forming course and the alternation of day and night, etc.
Description
The utility model relates to a kind of instruments used for education.
Existing Instrument for surveying solar time and azimuth will enclose and be designed to a broadband ring-type morning and evening, being mainly used in demonstration, tellurian day alternates with night etc., in order to demonstrate conveniently, many annexes also are installed on endless loop, though the annex that encloses morning and evening and install above all has excellent decoration, but shortcoming is that structure is complicated, annex has too much been strengthened the annex outside the earth main body, and the earth main body itself that weakened, use is easily misled to the pupil as instruments used for education, be unfavorable for teaching, also directly perceived inadequately to the demonstration of time zone and time.
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, the succinct more practicality of a kind of structure is provided, is more suitable in the space-time globe of teaching.
The purpose of this utility model reaches like this: the utility model includes geoid and earth axis, turning handle, outer turning handle and base, morning and evening circle, time scale ring and sun direct projection apparent place point.Turning handle upper end is provided with the arc brace, and turning handle is contained on the base by rotating shaft, and outer turning handle is set in the turning handle outside, and turning handle can rotate around the axis, and the outer turning handle handle that can rotate rotates.The earth is contained on the brace of turning handle upper end by earth axis.Earth axis and turning handle axle extensions intersect at geoid centre of sphere place.Morning and evening, circle was a fine circle, was loaded on the outer turning handle.Place, outer turning handle bottom is provided with a del mark, and this mark and morning and evening enclose in same plane.Seating plane is provided with month calibration loop, indicate above 12 month and the Spring Equinox, the Autumnal Equinox equinox and the Summer Solstice, Winter Solstice solstices, the time scale ring is and the close oblate ring of circle size in morning and evening, indicate the twenty four hours time scale above, the time scale ring is contained on the circle in morning and evening, and is positioned on the earth ecliptic plan; This ring is gone up time scale for increasing progressively from left to right, encloses joining in this ring and morning and evening and is denoted as at 6 o'clock and at ten eight o'clock, when zero and then laid respectively at double-edged middle position between these two points at ten two o'clock; Also indicate sun direct projection apparent place point at ten two o'clock places.
Indicating the hour hands mark near some time zone central meridian on the geoid, this mark and expression this time some important city names in this time zone when trivial corresponding, as Beijing, Tokyo, London etc., to represent Beijing time, Tokyo time etc.
The utility model practicality simple for structure, easy to use, be easy to carry, diverse in function can be demonstrated earth rotation, revolution, formation round the clock and replacement, the variation of length round the clock, the recurrent mutation of polar day, polar night, subsolar point intuitively, the variation of the formation in season and replacement, solar noon sun height, five bands divide etc., demonstrate twenty-four theory intuitively when trivial, and arbitrary place at a time is in position in changing round the clock on the earth, is more suitable for middle and primary schools' teaching and uses.
Do further narration below in conjunction with accompanying drawing:
Accompanying drawing is the utility model structural representation.
Among the figure: 1, enclose 2 morning and evening, geoid 3, earth axis 4, outer turning handle 5, base 6, month calibration loop 7, sun direct projection apparent place put 8, time scale ring 9, hour hands mark 10, del mark 11, rotating shaft 12, arc brace 13, turning handle
Hour hands mark 9, sun direct projection apparent place put 7 and del mark 10 be colored indicators, turning handle 13 is contained on the base 5 by rotating shaft 11, time scale ring 8 is the oblate ring of a horizontal positioned, its plane, place is the earth 's orbit plane, inboard thick, the outside of this horizontal circular ring approach, form a vision gradient, use with convenient.Enclosing 1 plane morning and evening overlaps with geoid 2 centre ofs sphere.Earth axis 3 becomes 66.5 degree angles with surface level (being the earth 's orbit face).
Claims (3)
1, a kind of space-time globe includes geoid and earth axis, turning handle and base, it is characterized in that also including circle in morning and evening, outer turning handle, time scale ring and big positive direct projection apparent place point; Morning and evening, circle was a fine circle, was loaded on the outer turning handle, and turning handle is loaded on the base by rotating shaft, and can rotate around the axis, outer turning handle is set in the turning handle outside, and the handle that can rotate rotates, place, outer turning handle bottom is provided with a del mark, and this mark and morning and evening enclose in same plane; Seating plane is provided with month calibration loop, indicate above 12 month and the Spring Equinox, the Autumnal Equinox equinox and the Summer Solstice, Winter Solstice solstices; The time scale ring is and encloses the close oblate ring of size morning and evening that indicate the twenty four hours time scale above, the time scale ring is contained on the circle in morning and evening, and is positioned on the earth ecliptic plan; This ring is gone up time scale for increasing progressively from left to right, encloses joining in this ring and morning and evening and is denoted as at 6 o'clock and at ten eight o'clock, when zero and then laid respectively at double-edged middle position between these two points at ten two o'clock; Also indicate sun direct projection apparent place point at ten two o'clock places.
