Description
Technical field
The utility model relates to a kind of Doppler effect comprehensive test instrument, belongs to teaching and experiment equipment technical field.
Background technology
In daily life, we can have this experience: when one arranges the train of the steam whistle that rings through out-of-date, can find that train becomes from blast of whistle time far and closely to ring, tone comes to a point, and train dies down from blast of whistle time closely and far, tone step-down, this is because the height of tone is determined by the difference of acoustic vibration frequency, if frequency is high, tone sounds just high; Otherwise tone sounds just low, and this phenomenon is called Doppler effect.Doppler effect is pointed out, ripple receive frequency when wave source shifts to observer uprises, and at wave source away from receive frequency step-down during observer, Doppler effect has a wide range of applications in fields such as scientific research, engineering, traffic administration, medical diagnosis, measuring techniques, such as: radar system be exactly based on Doppler effect away from, be applied to the monitoring of the velocity to moving target such as guided missile, satellite, vehicle; The detection of ultrasound wave medically to human body viscera active situation and velocity of blood flow is all carry out according to the principle of Doppler effect, Doppler effect is an important content in college physics teaching, common Doppler effect experiment instrument arranges a dolly in orbit, dolly is arranged ultrasound wave receiving end, one end of track arranges ultrasonic generator, when dolly is along track quick sliding, ultrasonic frequency changes, and control enclosure is shown Doppler effect is described.The ultrasonic generator of existing Doppler's experiment instrument is in ceaselessly emission state, if many people are simultaneously a laboratory operation, impact between ultrasound wave is obvious, cannot test simultaneously, and the transmit direction of ultrasonic generator is unidirectional, incapability realize between moving target and recipient in opposite directions with the experiment of opposing two kinds of mode of motion, and in the process of demonstration DeGrain, the operating troubles of some can be produced, be not conducive to the study of student and the teaching of teacher.
Utility model content
The purpose of this utility model is: for the defect of prior art, propose a kind of Doppler effect comprehensive test instrument, this experiment instrument structure is simple, arrange rationally, can realize between moving target and recipient in opposite directions with the experiment of opposing two kinds of mode of motion, and demonstration process in successful, any operating troubles can not be produced, be conducive to the study of student and the teaching of teacher.
The technical scheme that the utility model adopts is: a kind of Doppler effect comprehensive test instrument, comprise guide rail, one end of guide rail is provided with infrared receiver bracket component, the other end is provided with horizontal sensor generator, adjacently with horizontal sensor generator be provided with horizontal trolley, on guide rail, dolly is provided with between infrared receiver bracket component and horizontal sensor generator, one end of dolly is provided with charging pile near infrared receiver bracket component, the other end of dolly is provided with stop support assembly near horizontal sensor generator, wherein on horizontal trolley, be provided with transport tape, one end of transport tape is connected with dolly through stop support assembly, the other end of transport tape is connected with counterweight.
In the utility model: be provided with photoelectricity door bracket assembly between one end of described dolly and stop support assembly, adjacent with photoelectricity door bracket assembly, guide rail lower carriage assembly is provided with between photoelectricity door bracket assembly and stop support assembly, between the other end and charging pile of dolly, be equally also provided with guide rail lower carriage assembly, two guide rail lower carriage assemblies are all positioned on guide rail.
In the utility model: described dolly is provided with sensing receiver assembly, sensing receiver assembly carries out corresponding setting with horizontal sensor generator.
After adopting technique scheme, the beneficial effects of the utility model are: the utility model structure is simple, rationally distributed, can realize between moving target and recipient in opposite directions with the experiment of opposing two kinds of mode of motion, and demonstration process in successful, any operating troubles can not be produced, be conducive to the study of student and the teaching of teacher.
