Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to the revolution of earth apparatus for demonstrating that a kind of geographical teaching uses.
Background technology
At present, in middle and primary schools' Geography teaching, for revolution of earth, rotation feature, subsolar point along with the mobile Changing Pattern of revolution of earth, the generation of the north and south tropic and the four seasons formed, the knowledge point such as the revolution of the moon, because its content is more abstract, teacher normally by existing terrestrial globe and wall map for geography teaching be teaching aid explanation, student not easily understands, it is large to grasp difficulty, and therefore, the ocular demonstration of revolution of earth rule etc. is the difficult point of geographical teaching always.
Summary of the invention
For above-mentioned technical matters, it is simple that the utility model object is to provide a kind of structure, and demonstration is convenient, intuitively can show the revolution of earth apparatus for demonstrating of revolution of earth phenomenon and subsolar point movement law.
For achieving the above object, the technical solution adopted in the utility model is: revolution of earth apparatus for demonstrating, comprise solar model, terrestrial globe and order about the gear drive that described terrestrial globe revolves round the sun around solar model, solar model is arranged in a rotating shaft, rotating shaft is connected with an actuator, luminophor is provided with in solar model, described apparatus for demonstrating also comprises moon model, moon model is rotated around terrestrial globe by the gear drive be connected with terrestrial globe, rotating shaft is configured with solar panel, be installed on bottom rotating shaft on base, accumulator is provided with in base, described luminophor, solar panel is all connected with accumulator.
As the further restriction of technique scheme, described luminophor sends the ray light of optically focused point-like, to demonstrate the movement law of subsolar point in earth process of revolution intuitively.
As the further restriction of technique scheme, described terrestrial globe is arranged on bull stick, terrestrial globe can rotate bar rotation, bull stick axis is obliquely installed and makes the terrestrial globe equatorial plane and revolution orbit face form ecliptic obliquity, the light point of vertical that solar model sends gradually changes along with the revolution of the earth and rotation, the generation of convenient demonstration and the explanation north and south tropic and four seasons Formation rule.
Wherein, described actuator is micromachine, and micromachine is connected with accumulator, the electric energy work that micromachine utilizes solar panel to produce, and reduces the cost of manufacture of apparatus for demonstrating and energy-conserving and environment-protective.
Or described actuator is operating grip, and operating grip is fixedly connected with rotating shaft, adopts manual operation form to demonstrate, from the speed of Row sum-equal matrix gear drive, can conveniently observe the overall process of the sun, the earth, moon relative motion.
The beneficial effects of the utility model are according to known to describing of such scheme:
Above-mentioned revolution of earth apparatus for demonstrating utilizes simple mechanical principle, board design goes out revolution, the spinning motion rule of the earth, demonstrate the Changing Pattern of earth 's orbit subsolar point easily and intuitively, thus explain the spontaneous phenomenon such as formation, change round the clock in the four seasons; Meanwhile, this device is also equipped with moon model, is convenient to demonstration moon revolution and rotation rule, to explain the formation etc. of tide.Described apparatus for demonstrating structure is simple, easy to make, processing ease, is conducive to the relative motion law that learner understands quickly and grasps the sun, the earth, the moon, improves learning efficiency.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress.
