Abstract

A multifunctional globe comprises a globe body, a globe shaft, a rotary handle, a base, a morning and evening circle, a sun direct-emitting point and a support. The morning and evening circle is a thin circular ring and is arranged on a rotating handle which is arranged on a base, and a marking line is arranged at the bottom of the rotating handle and is in the same plane with the morning and evening circle. The base surface is provided with a month scale ring. One end of the bracket is arranged on the morning and evening circle, and the other end is provided with a direct solar radiation point. The utility model discloses the structure is succinct practical, the function is many, multiple natural phenomena such as demonstration revolution of the earth, rotation, formation round the clock and replacement can be audio-visual.

Description

Multifunctional globe

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, its advantage is, the annex that encloses morning and evening and install above all has excellent decoration, but shortcoming is that structure is complicated, annex is too much, has 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, is unfavorable for teaching.

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 multifunctional globe of teaching.

The purpose of this utility model reaches like this: the utility model includes geoid and earth axis, turning handle and base, morning and evening circle, subsolar point and support.The turning handle upper end is provided with the arc brace, and turning handle is contained on the base by rotating shaft, and turning handle can rotate around the axis.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 turning handle.Place, turning handle bottom is provided with one and indicates line, and this indicates line and enclose morning and evening 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, support shape and length are identical with the quadrant camber line that encloses fine circle morning and evening, support one end is contained in the horizontal diameter of circle in morning and evening and encloses the intersection point place morning and evening, and the other end is equipped with subsolar point.It is perpendicular that plane, support place and morning and evening are enclosed the plane.

In morning and evening circle and support connection place, be provided with a little joint, when support is opened, its position just in time with morning and evening circle vertical, when support is turned up can with enclose morning and evening parallel.Easy to carry and use.

Equatorial line also is one day twenty four hours time scale line simultaneously, with 24 warp intersections, indicates the twenty four hours time scale under the line.The high noon of Beijing time, ten two positions were in Dong Ba district central meridian and intersection, equator, and central meridian place, Dong Jiu district is ten one points, and central meridian place, seven districts, east is ten three points, and the like.

The utility model practicality simple for structure, easy to use, be easy to carry, diverse in function, can demonstrate earth rotation, revolution, formation round the clock and replacement, the variation of length round the clock intuitively, the recurrent mutation of polar day, polar night, subsolar point, the variation of the formation in season and replacement, solar noon sun height, five bands divide etc., and arbitrary place at a time is in round the clock position in changing 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 3 in earth axis 2, morning and evening, geoid 4, equatorial line 5, turning handle 6, month calibration loop 7, base 8, indicate line 9, support 10, joint 11, subsolar point 12, arc brace 13, rotating shaft

Indicating line 8 is colored indicators, directly is indicated in place, turning handle 5 bottoms.Turning handle 5 is contained on the base 7 by rotating shaft 13, and plane, support 9 place is the earth 's orbit plane.Enclosing 2 planes morning and evening overlaps with geoid 3 centre ofs sphere.Earth axis 1 becomes 66.5 degree angles with surface level (being the earth 's orbit face).

Subsolar point 11 is the time spent not, support 9 can be folded up, and encloses 2 and together morning and evening, convenient carrying.

Claims
