Description
Technical field
The present invention relates to a kind of infrasonic wave generating device, a kind of specifically high-power infrasonic wave generating device.
Background technology
The sound wave that frequency is lower than 20Hz (hertz) is called infrasound, and infrasound is that people's ear institute is unheard.Infrasound can be propagated with the speed of 1200km per hour in air, can propagate the concrete that penetrable 1.5m is thick with the speed of 6000km per hour in water.The intrinsic frequency of the many organs of human body in 2～16Hz scope, is 4～6Hz as internal organ all, and head is 8～12Hz etc.These intrinsic frequencies of human body just in time in infrasonic frequency range, when powerful infrasound acts on human body, will cause the resonance that human body is strong, thereby damage.Subaudio weapon is exactly that the infrasound and the human body that utilize frequency to be lower than 20Hz resonate, and makes that the organ of resonance or position are subjected to displacement, distortion or loss of function and cause injury of human so that dead.
Be the tolerant infrasound intensity of checking human body, people once used dog, monkey and the baboon close with the human body tolerance to do experiment.The result shows: dog significantly expiratory dyspnea occurs under the high-strength infrasonic sound effect of 172dB (decibel), have in addition stopped breathing; The respiration rate of monkey and baboon also obviously reduces; When intensity reached 185～195dB, in the not long time, tested animal was all dead.Through research repeatedly, scientists finds that infrasound intensity is about 140dB, even the short change that also can cause human viscera organ's function aspect action time; When rising to 150dB, then can cause the pathology of human organ; As follows sound intensity raises again, will cause death.
According to the stimulus to the sense organ classification, the infrasonic weapon of developing at present can be divided into two kinds.A kind of is the nervous system type infrasonic weapon, and it stimulates people's nerve by the infrasound of " alpha rhythm " of tranmitting frequency and human brain close (about 5Hz), makes the dizzy headache of people, amentia.Another kind is the organotypic infrasonic weapon, and quite (4～8Hz) infrasound makes the people symptoms such as n and V, stomachache, expiratory dyspnea occur by tranmitting frequency and human body viscera intrinsic frequency.
As far back as the sixties in last century, subaudio weapon is just competitively studied by developed country.A strong time acoustic generator is made in French national experimental center in 1972, and test first just makes 5 kilometers to come to harm with interior personnel.The eighties in last century, French scientist Jia Fuluo made a kind of " big zufolo " inferior acoustic generator, and sound pressure level is 160dB, can produce damage to human organ, and French at that time newspaper claims that it is " an infrasonic sound rifle ".
AUS weapon research department develops a kind of trumpet type sound big gun that may extend to 17 meters long, transmitting power reach 20kW (kilowatt).The seventies in last century, U.S. police have developed and the people " have been ossify " or hors de combat infrasonic weapon, control riot.It is said when the U.S. interferes Bosnai Hercegovinai'sCivil War, 1992-1995 that once these non-fatal infrasonic weapons of secret just made plug army position fall into general disorder only several seconds, the someone faints, and the someone keeps vomiting.
Weapon with respect to traditional concept, that subaudio weapon has is disguised strong, spread speed is fast, propagation distance is far away, penetration power is strong, free from environmental pollution and destroy characteristics such as facility, thereby be listed in the important member of new concept weapon family, certainly will become the weapon new lover on the future battlefield.
Producing infrasonic principle of device at present, mainly is to produce oscillating signal with oscillating circuit, after power amplification circuit amplifies, drive loudspeaker output infrasound, but this method circuit complexity, reliability is low, particularly is difficult to export thousands of watts high-power infrasonic wave.In addition,, utilize bomb blast also can produce high-strength infrasound, but bomb can only disposablely use by appropriate design, non-adjustable, uncontrollable, need drop a bomb, be unfavorable for hidden.
Summary of the invention
The object of the present invention is to provide a kind of high-power infrasonic wave generating device.This device has that power output is big, frequency adjustable, working stability, characteristics such as easy to maintenance, for the research of high-power infrasonic wave and lay the foundation in the application aspect the weapon.
For achieving the above object, the invention provides a kind of device that utilizes mechanically operated method to produce high-power infrasonic wave.This device partly is made of alignment circuit, buncher, cam or eccentric wheel, slide block, drive link and output loudspeaker etc.; Or partly constitute by diesel oil or petrol engine, gearbox, cam or eccentric wheel, slide block, drive link and output loudspeaker etc.Alignment circuit is with the rotating speed of buncher, perhaps diesel oil or petrolic transformation of speed are transferred to 1～20 revolutions per second by gearbox, motor shaft or output shaft of gear-box drive eccentric wheel and rotate, eccentric wheel is transferred to first connecting rod by bearing with kinetic energy, first connecting rod drives slide block by universal joint and do the linear reciprocation slip in chute, and the drive second connecting rod, drive the output loudspeaker by second connecting rod and move reciprocatingly, the output high-power infrasonic wave.
The output power range of this device is from several hectowatts to tens kilowatt, has that power output is big, frequency adjustable, working stability, characteristics such as easy to maintenance.
Described buncher is controlled rotating speed by alignment circuit, and changes the axle circular motion of motor into straight reciprocating motion by cam or eccentric wheel, slide block, drive link, and promotes the output loudspeaker, produces high-power infrasonic wave.
Described diesel oil or petrol engine change the axle circular motion of motor into straight reciprocating motion by cam or eccentric wheel, slide block, drive link, and promote the output loudspeaker, produce high-power infrasonic wave.
