Description
Technical Field
The utility model relates to a fire-extinguishing apparatus technical field, concretely relates to sound wave extinguishing device.
Background
The conventional fire extinguisher contains foam, dry powder, alkyl halide or carbon dioxide, and even if the fire extinguisher is incombustible, the fire extinguisher can expand and burst after being baked, fragments of a tank body are dangerous, and the gas extinguishment is easy to cause suffocation, so that the use of a closed space is dangerous. Sound propagates in the air as longitudinal waves, thereby changing the density of the air medium. If it is considered that substances such as oxygen and carbon dioxide in the air are uniformly distributed in a certain area, the oxygen in the area is also distributed sparsely and densely under the influence of sound waves of a certain frequency, and the oxygen content is thin, so that the oxidation effect is not convenient to generate and the combustion phenomenon is generated.
Acoustic waves propagate in all directions through various media. The acoustic wave is generally a longitudinal wave and also a transverse wave, and a particle where the acoustic wave arrives vibrates near an equilibrium position along a propagation direction, and the propagation of the acoustic wave is substantially energy transfer in a medium. The wavelength of the ultrasonic wave is shorter than that of the general sound wave, and the ultrasonic wave has better directivity.
Based on the principle, the sound wave fire extinguisher is generated, for example, a low-frequency sound wave fire extinguisher disclosed in the Chinese patent with the publication number of CN204932657U in the prior art comprises a sound wave generator, a power amplifier, a loudspeaker and a sighting device which are sequentially connected, wherein the sound wave generator emits sinusoidal sound waves of 30Hz-60Hz, the sinusoidal sound waves are amplified by the power amplifier and then transmitted to the loudspeaker, the sighting device comprises a cylinder body, a sound wave inlet and a sound wave outlet are formed in the cylinder body, and the diameter of the cylinder body is gradually reduced from the sound wave inlet to the sound wave outlet. Compared with an ultrasonic fire extinguisher, the high-frequency sound wave fire extinguisher uses the low-frequency sound wave, solves the problem that the fire extinguishing effect is poor because the high-frequency sound wave only enables the fire to oscillate, but because the directivity of the 30Hz-60Hz sinusoidal sound wave is poor, the patent needs to arrange a sighting device to improve the directivity of the 30Hz-60Hz sinusoidal sound wave, meanwhile, the 30Hz-60Hz sinusoidal sound wave is in the audible sound wave frequency range of human ears (20Hz-20KHz), the sound wave energy for fire extinguishing is high, and large-range noise pollution can be generated.
