Abstract
The utility model discloses a day and night alternation demonstrating instrument consisting of a pedestal 1, a tellurion sphere body 2 and a support rack 3, wherein a light shielding body 4 having a hemisphere-shaped structure is arranged in the tellurion sphere body 2, the outer wall of the light shielding body 4 is painted in black, a universal wheel 6 is arranged between the light shielding body 4 and the inner wall of the tellurion sphere body 2, the universal wheel 6 is fixedly connected on the outer wall of the light shielding body 4, the universal wheel 6 consists of a connecting body 7 and a rolling ball 8, the middle part of the support rack 3 is provided with a permanent magnet block A5, the inner wall of the light shielding body 4 is provided with a permanent magnet block B9, the tellurion sphere body 2 is rotated, the light shielding body 4 and the universal wheel 6 move on the inner wall of the tellurion sphere body 2 under mutual attraction of the permanent magnet block A5 and the permanent magnet block B9, one half of the tellurion sphere body 2 is clear in map display while the other half is unclear in map display, and therefore day and night alternation demonstrating effects are exerted. Through use of the day and night alternation demonstrating instrument, learning enthusiasm of students can be triggered, and the students can be helped to well grasp knowledge.
Description
Technical field
The utility model relates to a kind of teaching aid, the concrete day and night change demonstrator of a kind of geographical teacher in the time of the didactics dried rhizome of rehmannia revolutions phenomenon knowledge that produces that day alternates with night that relate to.
Background technology
The earth is not luminous opaque spheroid again, and same sunlight in a flash can only illuminate ball half, and half earth being illuminated by sunlight is daytime, and half earth not illuminated by sunlight is night.Due to ceaselessly rotation from West to East of the earth, on the earth, carry out from east to west that day alternates with night, the cycle that day alternates with night is 24 hours.Day alternates with night has not only regulated the atmospheric temperature of earth surface, is also very favourable for the survival and development of organic sphere on the earth.Geographical teacher, in the time of the didactics dried rhizome of rehmannia revolutions phenomenon knowledge that produces that day alternates with night, explains textbook content by school wall map often, and this method is too abstract, and student understands difficult.Application number is 2012200203943 one demonstrating globe utility model patent round the clock, although a solution is provided, need to have the support of power supply to demonstrate.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing in order to solve prior art, and a kind of day and night change demonstrator is provided.
The utility model solves the technical scheme that its technical matters adopts: a kind of day and night change demonstrator, by base 1, globe sphere 2 and support 3 form, it is characterized in that: the interior occulter 4 that arranges of globe sphere 2, occulter 4 is hemisphere shell-like structure, the outer wall coating black of occulter 4, between occulter 4 and globe sphere 2 inwalls, universal wheel 6 is set, universal wheel 6 is fixed on the outer wall of occulter 4, universal wheel 6 is made up of connector 7 and roller ball 8, support 3 middle parts arrange permanent-magnet block A5, occulter 4 inwalls arrange permanent-magnet block B9, connector 7 and roller ball 8 use insulating material are made, globe sphere 2 adopts translucent material to make, universal wheel 6 arranges more than three groups, permanent-magnet block B9 is arranged on occulter 4 inwall centers.
The beneficial effects of the utility model are: geographical teacher, in the time that the revolutions of the didactics dried rhizome of rehmannia produce day alternates with night phenomenon knowledge, can excite the enthusiasm of Students ' Learning, help student to grasp better knowledge.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is structural representation of the present utility model;
In accompanying drawing 1: 1. base, 2. spheroid, 3. support, 4. occulter, 5. permanent-magnet block A, 6. universal wheel, 7. connector, 8. roller ball, 9. permanent-magnet block B.
Embodiment
A kind of day and night change demonstrator, by base 1, globe sphere 2 and support 3 form, it is characterized in that: the interior occulter 4 that arranges of globe sphere 2, occulter 4 is hemisphere shell-like structure, the outer wall coating black of occulter 4, between occulter 4 and globe sphere 2 inwalls, universal wheel 6 is set, universal wheel 6 is fixed on the outer wall of occulter 4, universal wheel 6 is made up of connector 7 and roller ball 8, support 3 middle parts arrange permanent-magnet block A5, occulter 4 inwalls arrange permanent-magnet block B9, connector 7 and roller ball 8 use insulating material are made, globe sphere 2 adopts translucent material to make, universal wheel 6 arranges more than three groups, permanent-magnet block B9 is arranged on occulter 4 inwall centers.
Spheroid 2 rotates the globe, under the effect attracting each other at permanent-magnet block A5 and permanent-magnet block B9, occulter 4 moves on globe sphere 2 inwalls together with universal wheel 6, globe sphere 2 one hemisphere maps show obviously, second half spheroid map demonstration is not obvious, thereby reach the effect of day and night change demonstration.
Use the utility model can excite the enthusiasm of Students ' Learning, help student to grasp better knowledge.
