Abstract

The invention relates to a low-frequency sound wave fire extinguisher. The low-frequency sound wave fire extinguisher comprises a power supply, a waveform generator, a power amplifier and a speaker; the power supply is used for supplying electric power for a whole system; the waveform generator is used for generating low-frequency sound wave simulation electric signals; the power amplifier is used for amplifying the low-frequency sound wave simulation electric signals; a sound cavity is mounted at a speaking end of the speaker; the speaker converts the amplified low-frequency sound wave simulation electric signals to sound waves for playing; and the sound cavity is used for directionally gathering the sound waves played by the speaker. The low-frequency sound wave fire extinguisher can use the sound wave energy for extinguishing fire without generating other adverse effects on peripheral objects in various special places.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a low-frequency sound wave fire extinguisher. Background technique [0002] The rapid development of human beings brings not only social progress, but also various hazards that affect the safety of human life and property. Fire is one of them. There are many kinds of traditional fire extinguishing methods, but the various fire extinguishing scenarios that firefighters have to face require far more fire extinguishing methods than the existing methods. For a series of special places such as electrical equipment places, special methods are required for fire extinguishing. For example, the use of gas fire extinguishing systems such as Halon series, carbon dioxide, etc. are often used in such places. However, the gas fire extinguishing system has some disadvantages: the misoperation of the gas fire extinguishing system in the confined space will threaten...
