Description
Technical field
The utility model relates to a kind of fire extinguisher, particularly relates to a kind of low-frequency sound wave fire extinguisher.
Background technology
Present technology of acoustic wave is very ripe, and is widely applied to a lot of aspect, and as ultrasound diagnosis medically, military radar fix, comprises acoustic toothbrush, shaver and industry cleaning link etc. in life.Current research finds: because fire extinguisher traditional in airtight, the microgravity and agravic environment of airship and lunar base is large because of weight, fire-fighting efficiency is low and can not put out a fire lastingly, very easily cause the shortcomings such as significant damage cannot find application in space fire casualty, and traditional fire extinguisher can adopt extinguishing chemical mostly, any extinguishing chemical will inevitably pollute airship or lunar base and destroy, in addition, in the weightless situation of space, extinguishing chemical can disperse everywhere, does not have fire extinguishing function.Therefore, market there is a kind of ultrasonic wave fire extinguisher being applicable to China Aerospace engineering, it is made up of telescoping handle, fire-resistant outer cover, supersonic generator, battery, conversion electric power, hand generator etc., although this ultrasonic wave fire extinguisher changes the drawback that conventional fire extinguisher must use extinguishing chemical, but it uses high frequency sound wave, facts have proved, high frequency sound wave can only make flare vibrate, and extinguishing effect is not good.2012, ARPA (DARPA) successfully to go out fire with two huge sound wave launching tubes, but equipment is heavy, operation inconvenience.
As can be seen here, prior art awaits further improving.
Utility model content
The utility model is the weak point avoiding above-mentioned prior art to exist, and provides that a kind of volume is little, lightweight, low-frequency sound wave fire extinguisher rapidly of putting out a fire.
The technical scheme that the utility model adopts is:
Low-frequency sound wave fire extinguisher, comprise the sonic generator, power amplifier, loudspeaker and the pointing instrumentation that are connected successively, sonic generator launches the sinusoidal sound wave of 30Hz ~ 60Hz, sinusoidal sound wave transfers to loudspeaker after power amplifier amplifies, pointing instrumentation comprises cylindrical shell, cylindrical shell is provided with sound wave inlet port and sound wave spreads out of mouth, the diameter of cylindrical shell passes exit and successively decreases gradually from sound wave inlet port to sound wave.
Described sonic generator comprises for generation of the single chip control module of sinusoidal sound wave, for controlling and selecting the keyboard of sinusoidal sound wave frequency and pass the LED display of the sound pressure level in exit for showing current frequency of sound wave and pointing instrumentation sound wave.
The resonant frequency of described loudspeaker is less than 35Hz.
The taper pipe of described cylindrical shell to be tapering be 1:3.
Described pointing instrumentation also comprises interface disc, and one end of interface disc is connected with loudspeaker, the other end is connected with cylindrical shell, and interface disc central authorities offer through hole.
Described cylindrical shell comprises shell, and the outer wall of shell is made up of cardboard, and the inwall of shell is made up of stainless steel.
Owing to have employed technique scheme, the beneficial effect acquired by the utility model is:
1, the utility model adopts sonic generator to produce low-frequency sound wave, well can be few, and cost is low, and volume is little, lightweight, and reliability is high, universal flexible.
2, the utility model adopts the low-frequency sound wave of 30Hz ~ 60Hz, and rapidly, noise is little, can be applied well in space fire casualty in fire extinguishing.
3, the utility model adopts in cardboard cylinder and pastes stainless steel as pointing instrumentation, and guidance quality is good, lightweight, receives, be conducive to sound wave and be delivered to burning things which may cause a fire disaster place in time, accurately, improve fire-fighting efficiency wave absorption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pointing instrumentation in the utility model.
Wherein,
1, sonic generator 2, power amplifier 3, loudspeaker 4, pointing instrumentation 41, interface disc 42, cylindrical shell 42.1, outer wall 42.2, inwall 42.3, sound wave spread out of mouth
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail, but the utility model is not limited to these embodiments.
When sound wave is propagated in atmosphere, the molecule in air can be made to vibrate back and forth near equilbrium position, from macroscopically, the just air stream of a series of density interphase, when sound wave frequency is to a certain extent low, namely, when the wavelength long enough of sound wave and sound pressure level reach some strength, the isolated time of flame and air just can be made to grow to and to make it extinguish.
As depicted in figs. 1 and 2, low-frequency sound wave fire extinguisher, comprise the sonic generator 1, power amplifier 2, loudspeaker 3 and the pointing instrumentation 4 that are connected successively, sonic generator 1 produces sinusoidal sound wave, this sinusoidal sound wave amplifies rear drive loudspeaker 3 through power amplifier 2 and works, and the sound wave that loudspeaker 3 exports is aimed at burning things which may cause a fire disaster by pointing instrumentation 4 and put out a fire.
Wherein, sonic generator 1 comprises single chip control module, keyboard and LED display, single chip control module is for generation of the sinusoidal sound wave of 30Hz ~ 60Hz, single chip control module comprises STC89C52 single-chip microcomputer, sonic generator 1 with this single-chip microcomputer for core, constitute a SCM Based sound signal generator, keyboard is for controlling and selecting the frequency of sinusoidal sound wave, power amplifier 2 amplifies for the sinusoidal sound wave produced single-chip microcomputer, and by regulating multiplication factor to regulate acoustical power, sinusoidal sound wave through amplifying is transferred to loudspeaker 3, loudspeaker 3 need possess good low frequency performance, the resonant frequency of loudspeaker 3 will at below 35Hz, pointing instrumentation 4 comprises cylindrical shell 42 and interface disc 41, one end of interface disc 41 is connected with loudspeaker 3, the other end is connected with cylindrical shell 42, interface disc 41 central authorities offer through hole, cylindrical shell 42 comprises shell, the outer wall 42.1 of shell is made up of cardboard, Main Function prevents pointing instrumentation 4 from operationally resonating, the inwall 42.3 of shell is made up of stainless steel, Main Function is the absorption reducing pointing instrumentation 4 pairs of sound waves, cylindrical shell 42 is provided with sound wave inlet port and sound wave spreads out of mouth 42.3, described cylindrical shell 42 is taperings is 1:3, length is the taper pipe of 33cm, that is the diameter of cylindrical shell 42 passes exit 42.3 and successively decreases gradually from sound wave inlet port to sound wave, the Main Function of pointing instrumentation 4 allows sound wave concentrate in a particular direction so that fire extinguishing, described LED display spreads out of the sound pressure level at mouth 42.3 place for showing current frequency of sound wave and pointing instrumentation 4 sound wave.
