Abstract
The utility model relates to a teaching aid, in particular to a Coriolis force demonstration instrument. The Coriolis force demonstration instrument comprises a base, wherein a horizontal rotating disk is arranged on the base, a stand column is vertically arranged on the horizontal rotating disk, the top part of the stand column is provided with a vertical rotating disk, the periphery of the vertical rotating disk is evenly distributed and fixed with a plurality of vertical ropes, every two vertical ropes are connected through a transverse rope, a plurality of throwing beads are installed on the transverse ropes, and the bottom part of the base is provided with at least one sucking disk. The Coriolis force demonstration instrument is stable in structure and simple in operation, can demonstrate the action of the Coriolis force directly, and deepens the understanding of the knowledge point of students.
Description
Technical field
The utility model relates to teaching aid, particularly a kind of Coriolis force demonstration instrument.
Background technology
Coriolis force (Coriolis force) is to carrying out straight-line particle in rotating system due to a kind of description of inertia with respect to the straight-line skew of rotating system generation.It is the reason of a lot of geographical phenomenons, Mechanics Phenomenon.As the formation of trade wind, on the Northern Hemisphere, the phenomenon such as the Southern Hemisphere is different to the degradation degree of two sides along the mobile river river of warp, and falling bodies track is by east, so the effect of Coriolis force is seen everywhere.But because this theory is very abstract, student is beyond affordability, it is always a difficult point of classroom teaching.What first historically proof Coriolis force existed is famous foucault pendulum experiment, but this device volume is huge and will obtain experimental result and will wait for a long time, is not suitable for doing on theoretical classroom.If a pendulum length is the Foucault pendulum of 1 meter, swing one hour, the deflection of swinging plane is just more than 7 °, instrument is heavy, phenomenon is slow, and because parameter is non-adjustable, can only see the result of this noninertial system effect of the earth, how fast, demonstrate intuitively the existence of Coriolis force, and instrument is light and handy, Portable belt, it is puzzlement Physical Education Teacher's a problem always.
Utility model content
The purpose of this utility model is to provide a kind of instrument can ocular demonstration Coriolis force existing.
The purpose of this utility model is achieved through the following channels: a kind of Coriolis force demonstration instrument, it is that horizontal rotating disc is installed on base, column is vertically installed on horizontal rotating disc, described column top is provided with vertical rotary dish, the periphery of vertical rotary dish has been uniformly arranged and fixed some and has erected rope, between perpendicular rope, by one section of horizontal rope, connect, on horizontal rope, several are installed and get rid of pearl, described base bottom is provided with at least one sucker.
As the further optimization of scheme, described sucker is four, and Cheng Si angle is symmetrically distributed in base bottom.
The utility model Coriolis force demonstration instrument Stability Analysis of Structures, simple to operate, can demonstrate very intuitively the effect of Coriolis force, deepen the understanding of student Dui Gai knowledge point.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
In figure, base 1, horizontal rotating disc 2, column 3, vertical rotary dish 4, perpendicular rope 5, horizontal rope 6, get rid of pearl 7, sucker 8.
Embodiment
As shown in Figure 1, the utility model Coriolis force demonstration instrument, it is, on the base 1 of making at metal material, horizontal rotating disc 2 is installed, column 3 is vertically installed on horizontal rotating disc 2, described column 3 tops are provided with vertical rotary dish 4, the periphery of vertical rotary dish 4 has been uniformly arranged and fixed some and has erected rope 5, between perpendicular rope 5, by one section of horizontal rope 6 connection, on one section of horizontal rope 6,3 plastics is installed and gets rid of pearl 7; Described base 1 bottom is provided with four suckers 8, and Cheng Si angle is symmetrical, by setting up this sucker 8, demonstrator can not toppled over because knockout press is excessive in presentation process.
During demonstration, one holds the horizontal rotating disc 2 of base 1 top, make horizontal rotating disc 2 fixing, another hand-drive vertical rotary dish 4, vertical rotary dish 4 is rotated around the horizontal axis of rotation, the pearl 7 that gets rid of that can observe on vertical rotary dish 4 edges all circles in same perpendicular, is the shape of a flower.
Vertical rotary dish 4 is when the axis of rotation rotates, drive horizontal rotating disc 2 that vertical rotary dish 4 is rotated around horizontal rotating disc 2 bolsters, there is change in the shape that can observe the flower that gets rid of pearl 7 formations, getting rid of pearl 7 has produced to the skew in or beyond vertical rotational plane, a glance is looked, and the edge that gets rid of pearl 7 has seemed wave.
Getting rid of pearl 7 reason being offset occurs, is because be subject to the effect of Coriolis force.
