Abstract
The utility model relates to a radio remote control earth movement demonstration and teaching instrument, particularly an electric teaching instrument for geography teaching, which is composed of an equator and ecliptic disk, a transverse rod, a globe, a frame which is provided with the globe, a micro motor, a synchronous motor, a worm, a gear, a fixing wheel, a rotary wheel, a red prefocus lamp representing the sun and a radio remote control switch. The utility model can incarnate that the earth revolution orbit is an elliptical orbit approximating to a normal circle, clearly explain obliquity of the ecliptic and changing rules of day and night and four seasons caused by the obliquity of the ecliptic, vividly and visually demonstrate the reciprocating movement phenomenon of the subsolar point between the tropic of capricorn and the tropic of cancer in the process of the earth revolution around the sun in a wireless remote control way.
Description
Technical field
The utility model relates to a kind of wireless remote control electronic teaching instrument of geographical teaching.
Background technology
The mankind own One Earth One Family together, and everybody likes my earth.The knowledge of relevant earth movements is important component parts of geographical teaching, its main teaching purpose is to disclose the regularity and the geographic significance thereof of earth rotation movement, revolution motion, make the student obtain the rudimentary knowledge of the earth and space environment, understand the principal character of human physical geographic environment of depending on for existence, and the mutual relationship between each key element of physical geographic environment, the meaning and the main path of understanding sustainable development, this is the mission of giving geographical educator the epoch.Therefore, manufacture and design the spontaneous phenomenon that a kind of energy is demonstrated the motion and the generation thereof of the earth visual in imagely, the novel geographical teaching instrument that the demonstration explanation day and night change and the four seasons form reason is beneficial to impart knowledge to students significant with social multi-faceted demand.
At present, " three-globe instrument " that generally adopt in geographical teaching is a kind of old product, and complex structure is difficult for adjusting, and earth's axis vergence direction changes easily, is not suitable for penetration and promotion.Another kind of commonly used instruments used for education " loxocosm " are though demo function is more, and its symbolistic sun represents with small-sized red ball that can not be luminous, tellurianly show that with white, black lining ball the sense of putting the cart before the horse is arranged round the clock, demonstrate not enough lifelike image.
Summary of the invention
Task of the present utility model is that to manufacture and design a kind of earth 's orbit that can embody be an approximate just round ellipse, be convenient to clarify ecliptic obliquity between ecliptic plan and the equatorial plane causes round the clock with the wireless remote control electronic teaching instrument of four seasons Changing Pattern.
Task of the present utility model is achieved in that terrestrial globe is arranged on the framework, rotates by micromotor, worm screw and gear driven terrestrial globe, as rotation.Rotate by gear driven one cross bar with a kind of synchronous motor in addition, the framework that terrestrial globe is housed is arranged on an end of cross bar, and framework rotates with cross bar, and terrestrial globe can be done revolution motion again.In order to make the earth's axis when the earth revolves around the sun, keep referring to aspect one, can add a fast pulley being arranged on the hollow vertical shaft that shows the ecliptic card, under the framework of device terrestrial globe, add a swiveling wheel and drive framework and rotate and get final product.The sun is represented with red spot light lamp bulb, is arranged on the top of hollow vertical shaft, passes through wire connecting power.Synchronous motor links to each other with radio remote control switch by lead, and radio remote control switch is by being connected to the plug energized that adds long lead.
The utility model is compared with " loxocosm " with above-mentioned " three-globe instrument ", have that to embody earth 's orbit be an approximate just round elliptical orbit, be convenient to illustrate ecliptic obliquity between ecliptic plan and the equatorial plane causes round the clock with four seasons Changing Pattern, by the projection of red spotlight on terrestrial globe, wireless remote control is demonstrated out the earth in the process of revolving around the sun, and subsolar point correspondingly comes and goes the phenomenon that moves between the tropic of north and south.
Description of drawings
Concrete structure of the present utility model can be given detailed introduction with reference to the embodiment accompanying drawing.
Accompanying drawing is the structural representation of the utility model embodiment
Among the figure, the 1st, terrestrial globe, the 2nd, the earth's axis, the 3rd, framework, the 4th, micromotor, the 5th, worm screw, the 6th, gear, the 7th, rotating shaft, the 8th, gear, the 9th, gear, the 10th, battery case, the 11st, switch, the 12nd, swiveling wheel, the 13rd, synchronous motor, the 14th, show the ecliptic dish, the 15th, base, the 16th, gear, the 17th, gear, the 18th, cross bar, the 19th, fast pulley, the 20th, hollow vertical shaft, the 21st, the red spot light lamp bulb of the expression sun, the 22nd, driving-belt, the 23rd, radio remote control switch, the 24th, be connected to the plug that adds long lead, the 25th, telepilot.
Embodiment
Micromotor 4 on framework 3 rotates, and by worm screw 5, gear 6, spinning motion is done in gear 8 driven wheels 9 and terrestrial globe 1 rotation.Synchronous motor 13 rotates, passes through gear 16, and gear 17 drives cross bars 18 and rotates, and cross bar 18 rotates and drives framework 3 rotations that device has terrestrial globe 1, makes terrestrial globe 1 do revolution motion.Constant for guaranteeing the earth's axis 2 directions, 3 times swiveling wheel 12 is housed at framework, framework 3 can rotate with swiveling wheel 12, links to each other with fast pulley 19 by driving-belt 22, the red spot light lamp bulb 21 of the expression sun is arranged on the top of hollow vertical shaft 20, passes through wire connecting power.Synchronous motor 13 links to each other with radio remote control switch 23 by lead, and radio remote control switch 23 is by being connected to plug 24 energized that add long lead.
