Abstract

The utility model relates to educational apparatus, and is a multifunctional globe. The existing globe is single in function, which is unable to satisfy teaching requirement. The multifunctional globe of the utility model comprises a globe body 1, a bracket 2, a pedestal 3, an hour circle 4, an ecliptic plane 5, a dawn-dusk ring 6, a midnight ring 7, a rotary disc 8, a central axle 9 and a 24 solar terms disk 10. Compared with prior art, the multifunctional globe increases functions, and can demonstrate the astronomical phenomena of the replacement of day and night, time change, the cause of four seasons, polar day, polar night, etc.

Description

Multifunctional globe

The utility model relates to instruments used for education, is a kind of multifunctional globe.

Existing terrestrial globe is a spheroid that is marked with map and energy rotation at its epidermis.Similarly instrument also has time zone terrestrial globe, transit and astronomical globe etc.These instrumental functions are single, can not satisfy the teaching requirement.

The purpose of this utility model is to provide a kind of chronometer phenomenon multifunctional globes such as demonstration time zone division, time conversion and the four seasons origin cause of formation that can melt intuitively.

The purpose of this utility model is achieved in that

Multifunctional globe, comprise spheroid (1), support (2) and base (3), the equator of spheroid is marked with 24 time zones, and be with the hour circle (4), spheroid is with a morning and evening cover concentric with spheroid outward, and it is formed by connecting by ecliptic plane (5), circle in morning and evening (6) and period of the day from 11 p.m. to 1 a.m circle (7), and is installed in the top of base axis (9) by rotating disk (8), be fixed on this top and overlap below the rotating disk, also have 24 solar term dishes (10).

Institute's target longitude is with consistent with institute's target on the spheroid to the district on the hour circle (4), and the hour circle is divided inside and outside two circles, and inner ring is the longitude time zone ring, is fixed on the spheroid equator, and the outer ring is 24 hour circles, can rotate.

Ecliptic plane (5) is garden, the plane circle that constitutes 26 fens angles of 23 degree with the equatorial plane of spheroid (1), giving the hour circle (7) is half garden circle, circle in morning and evening (5) is whole garden circle, they intersect 90 degree, all vertically pass ecliptic plane (5), intersect at rotating disk (8), with period of the day from 11 p.m. to 1 a.m circle and the corresponding ecliptic plane of ecliptic plane intersection point on, a subsolar point (12) is arranged.

One end of support (2) is fixed on the axis (9) of base, and the other end is connected with the axis of rotation (11) of spheroid, and axis (9) constitutes 26 minutes angle of 25 degree with the axis of rotation (11).

Rotating disk (8) drives cover rotation in morning and evening, and its rotating shaft is exactly the axis (9) of base, and rotating disk is carved with cue mark on (8), and the subsolar point of this mark and ecliptic plane is used to indicate a certain solar term of 24 solar term in same vertical plane.

Advantage of the present utility model and good effect are that mainly it has multiple function, can demonstrate day and night change, length, time conversion and time zone are divided round the clock, chronometer phenomenons such as move in the north and south that can also demonstrate subsolar point, the four seasons origin cause of formation and polar day polar night.

Be described further below in conjunction with drawings and Examples:

Fig. 1 is the multifunctional globe structural representation.

Among the figure, 1 is spheroid, and 2 is support, and 3 is base, and 4 is the hour circle, and 5 is ecliptic plane, and 6 are the circle in morning and evening, and 7 is period of the day from 11 p.m. to 1 a.m circle, and 8 is rotating disk, and 9 is axis, and 10 is 24 solar term dishes, and 11 is the axis of rotation, and 12 is subsolar point.

What embodiment provided is the multifunctional globe of a teaching usefulness, comprise spheroid (1), support (2) and base (3), the equator of spheroid is marked with 24 time zones, and be with the hour circle (4), spheroid is with a morning and evening cover concentric with spheroid outward, and it is formed by connecting by ecliptic plane (5), morning and evening enclosing (6) and give the hour circle (7), and is installed in the top of base axis (9) by rotating disk (8), be fixed on this top and overlap below the rotating disk, also have 24 solar term dishes (10).Institute's target longitude is consistent with institute's target on the spheroid with the time zone on the hour circle (4), and the hour circle is divided inside and outside two circles, and inner ring is the longitude time zone ring, is fixed on the spheroid equator, and the outer ring is 24 hour circles, can rotate.Ecliptic plane (5) is garden, the plane circle that constitutes 26 fens angles of 23 degree with the equatorial plane of spheroid (1), giving the hour circle (7) is half garden circle, circle in morning and evening (6) is whole garden circle, they intersect 90 degree, all vertically pass ecliptic plane (5), intersect at rotating disk (8), with period of the day from 11 p.m. to 1 a.m circle and the corresponding ecliptic plane of ecliptic plane intersection point on, a subsolar point (12) is arranged.One end of support (2) is fixed on the axis (9) of base, and the other end is connected with the axis of rotation (11) of spheroid, and axis (9) constitutes 26 minutes angle of 23 degree with the axis of rotation (11).Rotating disk (8) drives cover rotation in morning and evening, and its rotating shaft is exactly the axis (9) of base, and rotating disk is carved with cue mark on (8), and the subsolar point of this mark and ecliptic plane is used to indicate a certain solar term of 24 solar term in same vertical plane.

This terrestrial globe has multiple function.Rotating sphere can be demonstrated day and night change, length and will change the principle on date when the day line round the clock; Rotate 24 hour circles of the hour circle, can demonstrate time change and conversion; Rotate the circle in morning and evening, can demonstrate that subsolar point north and south is moved, the divisions of four seasons conversion and polar day phenomenon at polar night and five bands.In addition, the angle of cut of the ecliptic plane and the equatorial plane also shows very clearly.
