Description
Technical field
The utility model relates to terrestrial globe, especially relates to can determine the day-night length in somewhere one day and reflect Changing Pattern throughout the year a kind of and presents circle and the printing opacity terrestrial globe of subsolar point in morning and evening.
Background technology
Because earth rotation plane (equatorial plane) and revolution of earth plane (ecliptic plan) are 23 ° of 26 ' angles, therefore in earth ring revolves around the sun the process of a week (360 °), subsolar point (point of sun vertical irradiation is accepted on earth's surface) once comes and goes movement taking tropic year an as cycle between the earth north and south tropic (and be ± 23 ° of 26 ' angles of equatorial plane).
The earth is an opaque spheroid, and sunray can only illuminate the half (be daytime towards the hemisphere of the sun, downsun hemisphere is night) of earth surface, and daytime, the separatrix of hemisphere and night hemisphere was circle in morning and evening.Vertical with sunray (containing subsolar point light) owing to enclosing morning and evening, therefore morning and evening, circle was also to come and go mobile with the cycle in a tropic year apart from carrying out one between ° 26 ' angle of the earth's axis ± 23.
Earth surface is accepted varying in accordance with the time and the place of solar radiation energy, and this variation can embody by the variation of the variation of day-night length and height of the sun at noon.Day-night length has reflected the length of sunshine-duration, and height of the sun at noon has reflected the power of solar radiation.The two combines, and can express qualitatively one day somewhere and accept the number of solar radiation energy.Owing to enclosing the variation of position and the variation of the sun altitude mobile positive correlation with subsolar point morning and evening, therefore the north and south of subsolar point comes and goes to move and makes solar radiation energy distribution at the earth's surface have cyclical variation rule, and Zhe Yeshidi club presents the reason changing throughout the year.
Existing terrestrial globe is the earth model that a kind of people of being convenient to intuitively understand earth looks and geographic distribution, it only can embody the locus of somewhere on sphere, can not present the position of enclosing position and subsolar point morning and evening one day, more cannot determine somewhere day-night length and reflect Changing Pattern throughout the year one day.Therefore, people, in the geographic significance of cognitive earth movements, are difficult to obtain sufficient information and explanation from existing terrestrial globe, especially in the teaching of middle school geography.
Summary of the invention
The purpose of this utility model aims to provide can determine the day-night length in somewhere one day and reflect Changing Pattern throughout the year a kind of and presents circle and the printing opacity terrestrial globe of subsolar point in morning and evening.
The utility model is provided with base, C type support, model geoid, blanking disc, blanking disc pedestal, blanking disc support, segment rotating disk, turntable shaft and twenty-four solar terms index dial;
Described base, C type support and model geoid and existing terrestrial globe are same or similar; Described model geoid is formed by stacking by the Northern Hemisphere and the Southern Hemisphere; The upper supporting column of described C type support is provided with an axis hole and upper supporting column securing member, and the lower supporting rod of C type support is provided with a through hole and lower supporting rod securing member; Described blanking disc is the opaque disk that a diameter is slightly less than model geoid internal diameter, is provided with annular lamp holder in the front of blanking disc, is provided with LED lamp on annular lamp holder; Described blanking disc pedestal is positioned at blanking disc circle centre position, and blanking disc pedestal dead ahead is to being provided with a red laser transmitter, and is being provided with a pedestal rotating shaft with blanking disc parallel direction; Described blanking disc support is L-type, and blanking disc cantilever tip is provided with an axle sleeve coordinating with pedestal rotating shaft, and blanking disc support end is offered a through hole that can embed lower supporting rod; Described segment rotating disk be external diameter be slightly less than model geoid internal diameter and central angle be slightly larger than 46 ° 52 ' global shell, offer a rectangular through-hole in segment center of turntable position, a spacing nail that turns of fork-shaped is being set apart from 26 ' angle, 23 ° of segment center of turntable positions, be located at the spacing open slot nailing on that turns of fork-shaped and can embed blanking disc edge, fork-shaped is spacing to be turned that nail can be free to slide at blanking disc edge and freely rotates around self rotating shaft; Described turntable shaft is one and upper supporting column shaft hole matching cylinder, and turntable shaft lower end is provided with the rectangle axle head and the axle head securing member that coordinate with rectangular through-hole, and turntable shaft upper end connects with knob; On the face of described twenty-four solar terms index dial, be uniform-distribution with 24 scales and mark corresponding solar term title and date, twenty-four solar terms index dial is fixed on the upper end of upper supporting column; Described C type props up and is placed on base top, model geoid is hinged by upper supporting column and the lower supporting rod of upper supporting column securing member and lower supporting rod securing member and C type support, blanking disc is by blanking disc pedestal with to hide disc carrier hinged and be fixed on the end of the lower supporting rod of C type support, and segment rotating disk is hinged by the upper supporting column of turntable shaft and C type support.
On annular lamp holder, can evenly be provided with at least 2 LED lamps.
The just dead ahead to C type support of winter solstice on described twenty-four solar terms dial face.
External power supply can enter in model geoid by the through hole of the lower supporting rod of C type support.
The utility model, when use, according to forwarding knob mark to correspondence position exact date (or solar term day), (solar term day is just to solar term scale, non-solar term day adopts method of interpolation), after switching on power, the part that LED lamp group illuminates is hemisphere in daytime (part is night hemisphere in addition), and the separatrix of its light and shade both sides is the particular location this moment enclosing morning and evening.By enclosing morning and evening, can determine sun set/raise time and the day-night length in somewhere one day, and this day polar regions polar day scope at polar night.In addition, the luminous point that the red laser beam vertical with blanking disc presents at sphere is the particular location of this day subsolar point, and by subsolar point position and somewhere, the latitude value on model geoid can be extrapolated the height of the sun at noon on this ground of this day indirectly.
The utility model has increased on the basis of existing terrestrial globe describes effect and the demo function of the geographic significance of earth movements, and can double as indoor illumination.
The utility model uses the principle of relative motion, dexterously the rotation of the earth and the earth that causes of revolution are changed throughout the year and be converted into circle and the recurrent mutation of subsolar point in morning and evening, the position of morning and evening one day circle and subsolar point be can on terrestrial globe, directly present, thereby sun set/raise time, day-night length, height of the sun at noon and this day polar regions polar day scope at polar night in somewhere one day determined; In addition, in presentation process, can from terrestrial globe, reflect fast earth Changing Pattern throughout the year.Above-mentioned effect, contributes to understanding and the grasp of people to existence general knowledge and geographical knowledge.The utility model is on the basis of existing terrestrial globe, effect and the demo function of describing the geographic significance of earth movements are increased, and have the effect of room lighting and decoration concurrently, there is simple and reliable for structure, the advantage such as intuitive is strong, multiple functional, easy to operate, one-object-many-purposes, be particluarly suitable for applying in teenager's activity to popularize scientific knowledge, geographical teaching of primary and middle school.
