Description
Technical field
This utility model relates to a kind of foucault pendulum experiment apparatus for demonstrating, specifically a kind of foucault pendulum experiment apparatus for demonstrating suitable in science and engineering colleges and universities and each middle school teaching.
Background technology
1851, French scientist Foucault illustrates the pendulum being only limited by under action of gravity to people, and its swinging plane can change, and unique reasonably explanation is exactly that earth rotation causes that pendulum angle is in change, thus confirming the existence of earth rotation phenomenon, this pendulum is referred to as Foucault pendulum. For the principle to student's explanation and displaying Foucault pendulum, Dynamic Announce swinging track, the Austria probing into pendulum is close, and people devise the teaching aid of a lot of pendulum, and what have loads fine sand in swing ball, constantly descended leakage to describe swinging track by fine sand, what have installs magnetic paintbrush on swing ball, and then describes swinging track on magnetic drawing, and this kind of device is relatively more suitable for team teaching demonstration, but at the conventional classroom teaching that number is more, it is difficult to there is everybody visible demonstrating effect.
Summary of the invention
For problem above, the purpose of this utility model is to provide a kind of applicable conventional classroom instruction demonstration, foucault pendulum experiment apparatus for demonstrating easy and simple to handle.
For achieving the above object, this utility model adopts a kind of foucault pendulum experiment apparatus for demonstrating, including base, USB camera, rotary apparatus and swing ball, described rotary apparatus includes column and the entablature being connected with column and sill, described entablature and sill each connect respectively through upper center firmware and lower center firmware, bottom the firmware of described upper center, centre position is connected to swing rope, the end of described swing rope installs swing ball, described swing ball lower end is provided with spine, the centre position of described lower center firmware is provided with centre bearing, the centre position of described base is provided with the central shaft of hollow, described rotary apparatus is coordinated with the central shaft on described base by the centre bearing of described lower center firmware and is rotatably connected, described central shaft cavity inner top arranges USB camera, USB connecting line it is connected to bottom described USB camera, described USB connecting line is connected with computer.
As preferably, the spine of described swing ball lower end is the mark that described USB camera follows the trail of the motion of described swing ball.
As preferably, described rotary apparatus is manually stirred rotation or drives rotation by motor.
During work, described rotary apparatus can simulate earth rotation, swing ball motion conditions described in described USB camera record, and by VB Programming with Pascal Language, shows movement locus calculating in real time on owner interface.
When this utility model uses, first swing ball is pulled to make it swing, then rotary apparatus is driven, it is made to simulate earth rotation effect, by VB Programming with Pascal Language, USB camera can automatically record and show swing ball movement locus, can show in real time on calculating owner interface, also can pass through multimedia equipment projection to show, simple and convenient, effect is obvious. This utility model is applicable to the Foucault pendulum related experiment of science and engineering colleges and universities and each middle school teaching, perfect in shape and function, and cost performance is high.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment.
Detailed description of the invention
As shown in Figure 1, specific embodiment of the utility model is a kind of foucault pendulum experiment apparatus for demonstrating, including base 10, USB camera 7, rotary apparatus and swing ball 4, described rotary apparatus includes column 6 and the entablature 1 being connected with column 6 and sill 8, described entablature 1 and sill 8 each connect respectively through upper center firmware 2 and lower center firmware 9, bottom described upper center firmware 2, centre position is connected to swing rope 3, the end of described swing rope 3 installs swing ball 4, described swing ball 4 lower end is provided with spine 5, the centre position of described lower center firmware 9 is provided with centre bearing, the centre position of described base 10 is provided with the central shaft of hollow, described rotary apparatus is coordinated with the central shaft on described base 10 by the centre bearing of described lower center firmware 9 and is rotatably connected, the cavity inner top of described central shaft arranges USB camera 7, it is connected to USB connecting line 11 bottom described USB camera 7, described USB connecting line 11 is connected with computer.
Wherein, the spine of described swing ball lower end is the mark that described USB camera follows the trail of the motion of described swing ball, and described rotary apparatus is manually stirred rotation or rotated by motor driving.
