Embodiment Construction

[0021] Such as figure 2 , image 3 and Figure 4 As shown, the water vortex principle demonstrator caused by the rotation of the earth includes a rotating base 1, a demonstrator 2, a transmission 3, and a driving motor 4. The demonstrator, the driving motor, and the transmission are fixed on the top surface of the rotating base. The demonstration surface of the demonstrator is There are at least three rectilinear motion areas on the top, and the three rectilinear motion areas realize horizontal motion in the same direction but at different speeds or in the same direction at the same speed through the drive motor and transmission;

[0022] Such as image 3 As shown, the rotating base is further described, the rotating base 1 is mainly composed of a base plate 101, a bearing 102 and a rotating plate 103, and the rotating plate can rotate horizontally on the plate surface of the base plate through the bearing;

[0023] Such as Figure 4 As shown, the demonstrator 2 includes ...

Abstract

A principle demonstrator for a water whirlpool caused by earth rotation comprises a rotatable base, a demonstrator device, a speed changer and a driving motor. The demonstrator device, the driving motor and the speed changer are fixed on the top surface of the rotatable base. The demonstrating surface of the demonstrator device is provided with at least three linear motion areas which are divided.Same-direction and different-speed horizontal movement or same-direction and same-speed horizontal movement of the three linear motion areas is realized through the driving motor and the speed changer. Through the movement speeds of the three linear motion areas, the forming principle of the water whirlpool and a movement principle of an equator and two pole points are demonstrated.

Description

technical field [0001] The invention relates to the field of popular science teaching aids, in particular to an instrument for demonstrating the principle of a water vortex caused by the rotation of the earth. Background technique [0002] The earth rotates from west to east, and there is a rotation bias in the movement of objects. Objects moving on the earth will be deflected to the right in the northern hemisphere, and to the left in the southern hemisphere. This phenomenon is a non-inertial system of Coriolis force in the earth's rotation. Inertial force performance, we call it geostrophic deflection force. The linear velocity of rotation in the equator region is the highest (about 462m / s). As the latitude increases, the linear velocity becomes smaller and smaller, and decreases to zero at the pole. The formation of the water vortex is related to the rotation of the earth. [0003] The angular velocity of the earth's rotation is constant, and the circular section perpend...
