Abstract

The utility model discloses a rope wave and standing wave demonstrator mechanical and electrical device including a motor, a potentiometer, a battery holder, transmission machinery, a rope, a first support, a second support, and a third support. The motor, the potentiometer and the battery holder are in electrical connection and fixed on the first support. One end of the transmission machinery is connected onto the motor. The transmission machinery is fixed on the second support. One end of the rope is connected with the other end of the transmission machinery, and the other end of the rope is fixed on the third support. The rope wave and standing wave demonstrator mechanical and electrical device of the utility model can be used to intuitively demonstrate rope waves and standing waves, and the wavelength and frequency can be changed by regulating the potentiometer.

Description

Rope ripple, post ripple demonstration device machinery, electric device
Technical field
The utility model belongs to instruments used for education field, is specifically related to a kind of rope ripple, post ripple demonstration device machinery, electric device.
Background technology
The knowledge learning of high school physics mechanical wave one chapter, rope ripple is a special case in teaching material, never has for many years experiment teaching aid, all leans on teacher on blackboard, to use drawing with coloured chalk oscillogram.What the utility model experiment was observed is a real rope ripple sterogram, can not only observe rope wave propagation, and see the post ripple forming after reflection wave and incident wave stack simultaneously, has filled up a blank of Physical Experiment teaching aid.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of rope ripple, post ripple demonstration device machinery, electric device, can make up and there is no the sorry of corresponding experiment teaching aid all the time.
The utility model solves the problems of the technologies described above by following technological means: a kind of rope ripple, post ripple demonstration device machinery, electric device comprise motor, potentiometer, battery case, gearing, rope, the first support, the second support, the 3rd support, described motor, potentiometer and battery case are electrically connected to and are fixed on the first support, gearing one end is connected on motor, gearing is fixed on the second support, restrict one and be connected in the gearing other end, the other end of rope is fixed on the 3rd support.
Further, described rope ripple, post ripple demonstration device machinery, electric device also comprise switch.
The beneficial effects of the utility model: energy ocular demonstration rope ripple, post ripple, regulator potentiometer can change wavelength and frequency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of a kind of ripple of restricting of the utility model, post ripple demonstration device machinery, electric device;
Fig. 2 is the circuit diagram of a kind of ripple of restricting of the utility model, post ripple demonstration device machinery, electric device.
Embodiment
A kind of rope ripple, post ripple demonstration device machinery, electric device comprise motor 1, potentiometer 2, battery case 3, gearing 4, restrict the 5, first support 6, the second support 7, the 3rd support 8, described motor 1, potentiometer 2 and battery case 3 are electrically connected to and are fixed on the first support 6, gearing 4 one end are connected on motor 1, gearing 4 is fixed on the second support 7, restrict 5 one and be connected in gearing 4 other ends, the other end of rope 5 is fixed on the 3rd support 8, also comprises that switch is fixed on the first support 6.
Operation steps:
1, pack battery into power pack;
2, potentiometer is transferred to high order end;
3, open switch, slowly regulator potentiometer stops regulating after observing three all-waves, please classmates observe;
4, increase some output voltages, rope wave-wave length shortens, and it is large that frequency becomes, and can become four, five ... all-wave, continues classmates to observe;
5, increase output voltage, rope wave-wave length becomes shorter again, and frequency is higher, because an end points of restricting is fixed on motor, is connected mechanically, and it is equivalent to the oscillator of vibration source, and frequency, the wave frequency of oscillator equate.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
