Abstract
The utility model belongs to the technical field of teaching equipments and particularly relates to an earth rotation and revolution demonstrating device for geographical teaching. The earth rotation and revolution demonstrating device comprises a pedestal, a bracket, an oval-shaped orbit, a motor, an earth model and a power line, wherein one end of the bracket is fixed on the pedestal, a sun model is fixed at the other end of the bracket, and a plurality of bracket arms are arranged on the bracket; the oval-shaped orbit is horizontally arranged and fixed at the top of the bracket arms, a pulley is arranged on the oval-shaped orbit, and a fixed rod is arranged on the pulley; the motor is arranged at the end part of the fixed rod; and the earth model is fixedly connected to a rotating shaft of the motor. When the earth rotation and revolution demonstrating device for the geographical teaching is used, the power line is connected to a power supply, the pulley can move around the oval-shaped orbit, the earth model connected with the pulley can move around the oval-shaped orbit along the pulley, and meanwhile, the motor can drive the earth model to rotate around the rotating shaft of the motor to demonstrate the revolution of the earth around the sun and the earth rotation; and when the revolution of the earth around the sun and the earth rotation are demonstrated for students in class, the students can intuitively and visually understand the earth rotation and revolution, the classroom climate is enhanced, and the classroom efficiency is improved.
Description
Technical field
The utility model belongs to the teaching equipment technical field, relates in particular to a kind of geography teaching revolutions device for demonstrating revolution.
Background technology
Geographical teaching is various spontaneous phenomenons and humane phenomenon in the geographical environment of professor's student relevant earth surface, and a branch of instruction in school of the subject of mutual relationship between them.
The rotation of the earth and revolution are a kind of common knowledge in the geographical teaching, the earth around axis of rotation rotation from West to East simultaneously, also rotate around the sun by certain track, geographical teacher tends to do demonstration in the teaching of blackboard picture and to the student, it is not vivid to explain like this, can not allow student's lively study directly perceived, classroom efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of geography teaching revolutions device for demonstrating revolution, and the spontaneous phenomenon of demonstration earth rotation revolution that can not visual pattern when being intended to solve the revolution of explanation earth rotation causes the low problem of classroom efficiency.
The utility model is achieved in that a kind of geography teaching revolutions device for demonstrating revolution, and described geography teaching revolutions device for demonstrating revolution comprises: base; Support, an end of described support is fixed on the described base, and the other end of described support is fixed with solar model, and described support is provided with some support arms; Be fixed on the horizontally disposed elliptical orbit in described support arm top, described elliptical orbit is provided with coaster, and described coaster is provided with fixed bar; The end of described fixed bar is provided with motor; The rotating shaft of described motor is fixedly connected with earth model; And power lead.
As a kind of improvement, the rotating shaft of described motor be set to and surface level between angle be 66 ° of 34', the axis of described rotating shaft is by the centre of sphere of earth model.
As further improvement, described solar model is the rear luminous spheroid of energising.
Geography teaching revolutions device for demonstrating revolution comprises: base; Support, an end of described support is fixed on the described base, and the other end of described support is fixed with solar model, and described support is provided with some support arms; Be fixed on the horizontally disposed elliptical orbit in described support arm top, described elliptical orbit is provided with coaster, and described coaster is provided with fixed bar; The end of described fixed bar is provided with motor; The rotating shaft of described motor is fixedly connected with earth model; And power lead; When described geography teaching revolutions device for demonstrating revolution uses, power lead is received on the power supply, can move around elliptical orbit after the coaster energising, the earth model that is connected with coaster can move around elliptical orbit with coaster, motor can drive earth model around the rotating shaft rotation of motor simultaneously, when revolving around the sun, also demonstrated the demonstration earth rotation of the earth, say like this and demonstrate to the student class hour, make the rotation-revolution of understanding the earth of student's visual pattern, strengthen classroom atmosphere, improved classroom efficiency.
