Abstract

The utility model relates to a morning and night apparatus teaching apparatus which is composed of a movable plate 6 at the front and a static plate 18 at the back, wherein the movable plate and the static plate are correspondingly attracted together by a magnetic shaft center; the movable plate is made of an organic thin plate in a circular shape with a right square support, and an intersecting line of a right semicircle and a left semicircle is labeled as a morning and night line; the right semicircle is a transparent semicircle 4, and a circular metal plate 3 is arranged at the circle center of the right semicircle; a plurality of sun light rays are drawn from right to left on the right square support, and an arc-shaped metal plate 19 is stuck to the back side of the right square support. The static plate is made of a square organic thin plate, wherein an earth pattern which has the same size with the circle of the movable plate is drawn on the thin plate; a south frigid zone, a south temperate zone, a tropic of Capricorn, a tropical zone, a tropic of Cancer, a north temperate zone and a north frigid zone are labeled in the earth pattern; a circular magnet 10 is arranged at the center of the earth pattern; a summer solstice corresponding point 7, a vernal equinox and autumn equinox corresponding point 8 and a solstice corresponding point 9 are labeled at the right side of the earth pattern; a circular magnet 20 is arranged at the left of the vernal equinox and autumn equinox corresponding point. The utility model has the advantages of low cost, simple operation and easy study and understanding.

Description

A kind of Instrument for surveying solar time and azimuth instruments used for education

Technical field

The utility model relates to a kind of teaching aid.

Background technology

When at present middle school student take lessons in geography, lack instruments used for education, have only by figure static on the textbook and understand, particularly indigestion especially when demonstration morning and evening, study sun altitude.

Summary of the invention

The purpose of this utility model is exactly that a kind of make simple, cost Instrument for surveying solar time and azimuth instruments used for education low, easy to learn are provided in order to overcome the above problems.

The technical solution of the utility model is achieved like this: a kind of Instrument for surveying solar time and azimuth instruments used for education are characterized in: it is made of the moving plate 6 of front and the quiet plate 18 of back, and moving plate leans on the corresponding suction in magnetic axle center together with quiet plate; Described moving plate 6 is made by organic thin plate, roundedly adds right-hand holder, and left and right sides semicircle intersection is labeled as terminator 1, right semi-circle is transparent semicircle 4, circle centre position is equipped with circular metal plate 3, is decorated with many sunrays in right-hand holder from right to left, posts arc metal plate 19 at the right-hand holder back side; Described quiet plate 18 is made by square organic thin plate, on thin plate, be decorated with the pattern of the earth onesize with the circle of moving plate 6, be marked with the south frigid zone, the south temperate zone, the tropic of Capricorn, the torrid zone, the tropic of Cancer, north temperate zone, the north frigid zone at the pattern of the earth subscript, circular magnet 10 is housed in the centre of pattern of the earth, at the right side of pattern of the earth mark corresponding point 7 in the Summer Solstice, the Autumnal Equinox in Spring Equinox corresponding point 8, Winter Solstice corresponding point 9 are arranged, the Autumnal Equinox in the Spring Equinox corresponding point 8 the left side circular magnet 20 is housed.

The utility model cost is low, simple to operate, easily-learned easily mastered.

Embodiment

From Fig. 3 as seen, the utility model is made of the moving plate 6 of front and the quiet plate 18 of back, circular magnet 10 is equipped with at place, axle center at quiet plate, circular metal plate 3 is equipped with at place, axle center at moving plate, moving plate leans on the corresponding suction in magnetic axle center together with quiet plate, and staff can make template die intend sunray and return the track rotation by the sun.

Fig. 1 is the plate synoptic diagram.From Fig. 1 as seen, moving plate 6 is made by organic thin plate, roundedly add right-hand holder, left semicircle is opaque semicircle 2, and is also transparent, and right semi-circle is transparent semicircle 4, transparent semicircle 4 also can be and hollows out semicircle, left and right sides semicircle intersection is labeled as terminator 1, and circle centre position is equipped with circular metal plate 3, is decorated with many sunrays in right-hand holder from right to left.Post arc metal plate 19 at the right-hand holder back side.

Fig. 2 is a quiet plate synoptic diagram of the present utility model.From Fig. 2 as seen, quiet plate 18 is made by square organic thin plate, on thin plate, be decorated with the pattern of the earth onesize with the circle of moving plate 6, be marked with the south frigid zone 11, the south temperate zone 12, the tropic of Capricorn 13, the torrid zone 14, the tropic of Cancer 15, north temperate zone 16, the north frigid zone 17 etc. at the pattern of the earth subscript, circular magnet 10 is housed in the centre of pattern of the earth, corresponding point 7 in the Summer Solstice, the Autumnal Equinox in Spring Equinox corresponding point 8, Winter Solstice corresponding point 9 is arranged at the right side of pattern of the earth mark.The Autumnal Equinox in the Spring Equinox corresponding point 8 the left side circular magnet 20 is housed.

Because the earth is not luminous, an opaque spheroid, in the same time, the sun can only illuminate half of earth surface, hemisphere towards the sun is daytime, downsun hemisphere is night, daytime hemisphere and night hemisphere the boundary coil be called terminator or morning and evening coil, the residing state round the clock in arbitrary time earth various places can be expressed with altitude of the sun.Altitude of the sun is the abbreviation of sun altitude, various places on daytime hemisphere, altitude of the sun is always greater than 0 °, be the sun on the local horizon, the various places altitude of the sun on terminator equals 0 °, promptly the sun just is positioned on the local horizon, various places on night hemisphere, altitude of the sun is always less than 0 °, and promptly the sun is positioned under the local horizon, because the earth ceaselessly moves and also constantly replacing round the clock.Since the recurrent mutation of subsolar point, earth surface formed two minutes two to, occurred that the days are long and the nights short, the variation in the four seasons and five bands are divided.During as the sunshine direct projection tropic of Cancer should be the Summer Solstice of the arctic, and polar day has appearred in the arctic, and Northern Hemisphere daytime is greater than night.The utility model is the above-mentioned phenomenon of dynamic demonstration well.
