Description

Demonstrate terrestrial globe synchronously

The utility model relates to simulate a kind of demonstration equipment of the earth.Existing terrestrial globe normally is made of the earth, support, pedestal, and the earth is installed on the stand base by rotating shaft, and the moving spheroid of armrest is realized rotatablely moving.Its weak point is, can not simulate the working order of the earth truly.It can only manual activity.

The purpose of this utility model is to avoid weak point of the prior art, and provide a kind of can with earth synchronous operation, the terrestrial globe product of real simulation earth working order.

Can take following technical scheme to realize purpose.Except that the earth, rotating shaft, pedestal, it also has the Vidacare corp by the control of clock wheel module, and drive unit is installed in the pedestal, drives the rotation of the earth and the rotation of simulated solar plate respectively through reducing gear and clutch coupling, makes electronic synchronously globe.

Also can adopt the luffing of solar panel to replace the mode of the rotation of solar panel rotation to simulate the phenomenon that 1 year sun changes the earth sunshine.In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of demonstrating terrestrial globe synchronously.

Fig. 2 is the clutch coupling synoptic diagram.

Fig. 3 is an alternative plan structural representation of demonstrating terrestrial globe synchronously.

With reference to figure 1, because drive unit (12) is controlled by the clock wheel module, and 1 12 hours weeks of clock train revolution, be equipped with reducing gear (13), just can realize simulating being synchronized with the movement of earth rotation from West to East, cause in the specific constructive form of drive unit and then can select as one sees fit with the angular velocity in per 24 hours one weeks.

In the example, Vidacare corp (12) is main by the clock wheel module that is in transmission connection successively as shown in Figure 1, step motor, and reducing gear (13) is formed.Output terminal links through clutch coupling with the earth (17) and the axle sleeve (10) that drives solar panel respectively.Drive unit can adopt dry cell (15) or external power supply power supply.

For making the demonstration terrestrial globe possess manual function or do necessary adjustment, thus system design rolling-reset axial cone formula clutch coupling.Be provided with rotary handle (14) in (its structure as shown in Figure 2) mechanism, after the human hand is moved, pull line (30) makes the friction cover (21) of clutch coupling do the angle that turns clockwise, another friction cover (27) is done and is rotated counterclockwise an angle, because steel ball (24) is arranged at their bottom, its part is heavy to crouch in the groove of location-plate (25), the pressure that when friction cover (21) and (27) rotation, forces ball to go out groove and overcome spring (28) make friction cover (21) and friction axle (22) simultaneously (26) and (27) broken away from the friction fit face of axial cone, make them break away from swivel-chain, the ground spherical shell can freely be rotated, and solar panel can freely change by (22).Finished the manual adjustment function.

When synchronous operation is done by system, handle (14) (with reference to figure 1) can be resetted, make the clutch coupling combination.System's clock and watch train driven by stepper motors (12) drives the earth (17) to rotate with geosychronous angular velocity through the angular velocity that reducing gear (13) obtains per 24 hours one weeks.Meanwhile reducing gear (13) is also exported an axle sleeve (10) with the rotation of the angular velocity in 365.25 days 1 weeks, in order to drive the rotation of solar panel (6).Since the ground axial rake be 66 ° 34 ', so system design the bearing that tilt to rotate, the axis of its bearing outside become with the axis of bearing center 66 ° 34 ' intersect inclination.It is made up of with steel ball (18) and slip rotatable lamella (9) the oblique core of bearing (4) (fixedly connected with the earth's axis (5) (4)).When turning set (10) is driven around the earth's axis (5) when rotating, stir rotatable lamella (9) by its driving lever (the turning set axle head is provided with in the hole that driving lever and driving lever insert rotatable lamella (9)), the simulated solar plate (6) that is fixed on (9) and lighting bulb (7) etc. are done under the supporting of steel ball (18) around the oblique core of bearing (4) rotated.

Change at day, the moon, solar term, sunshine for the ease of showing, in the ground spherical shell, be provided with the pilot lamp (1) of display ball (2) and demonstration time.

Obtain power supply for making in the ground spherical shell, system is provided with sliding ball electric supply installation such as brush holder (3) and current collection ball.

The utility model also provides another kind of scheme to realize, as shown in Figure 3, this programme is the pitching swing that the circular motion of protosun plate is become solar panel, its amplitude is to be that the center is done and caused the tropic of Cancer with the equator, causing the tropic of Capricorn down comes simulated solar throughout the year to the earth variation at sunshine, be equivalent to the sun is that object of reference is observed the earth, structure Central Plains drives axle sleeve (42) end of solar panel rotation and makes angled end-face garden cylindricality, the inclination angle on inclined-plane equals the angle between the tropic of north and south, the inclined-plane circles, reciprocal inclination one-period then, be delivered on the plane (34) that connects solar panel by the variation of roller ball (33) on the inclined-plane the inclination angle, (the pitching center of oscillation of plane (3) is fixed on the column (37) by little axle (36)) axle sleeve (17) so whenever rotates a circle, solar panel is done a pitching hunting period, finished the sun at all seasons in to changing at sunshine of the earth.

System is in order to broaden one's vision, and the support of being convenient to observe former terrestrial globe removes, and the whole earth is showed the true colours of the earth by the center ground axle suspension with brand-new appearance and modeling.To reach the effect of synchronization simulation.

The relative prior art of the utility model has following advantage:

1. Can with earth synchronous operation, the working order of the real simulation earth, whole system Can intuitively reproduce daytime, the night of tellurian different regions, the time difference of different regions, the utmost point Daytime, polar night, sunrise, sunset time and 1 year natural phenomena such as 24 solar term variations at sunshine.

2. The utility model has removed the semi-circular support of existing tellurion in appearance and modeling, Therefore enlarge field of view, more truly reproduced the true colours of the earth.

3. system can be electronic, also can manual adjustment, and have multiple functions such as punctual clock, calendar, illumination, decoration, integrate science popularization, teaching, practicality, view and admire.
