Fire-fighting boat with sound wave fire-extinguishing function

Abstract

The invention relates to the technical field of fire-fighting boats, in particular to a fire-fighting boat with a sound wave fire-extinguishing function. The fire-fighting boat comprises a hull, the outer surface of the hull is provided with a boat body, the top end of the boat body is provided with a cab, the outer surface of the boat body is fixedly provided with a sound wave fire extinguisher,the right side of the sound wave fire extinguisher is provided with a control mechanism, a rotating base is arranged at the top end of the control mechanism, the sound wave fire extinguisher comprisesa buckling base, and the buckling base is fixedly installed on the upper surface of the boat body. According to the fire-fighting boat, through arrangement of an audio frequency emitter, a handle, anamplifier and a concentration pipe, when a fire source needs to be extinguished, the device can emit low-frequency sound waves of 30-60 Hz through work of the audio frequency emitter and the amplifier, and combustibles and oxygen can be isolated during sound wave propagation in air only by aligning a pipe opening to the fire source and through pressure waves of the low-frequency sound waves, therefore, no-damage fire extinguishing is achieved, and the practicability of the fire-fighting boat is higher.

Description

technical field [0001] The invention relates to the technical field of fire fighting boats, in particular to a fire fighting boat with sound wave fire extinguishing function. Background technique [0002] Sound is produced by the vibration of objects. In the vibrating medium, a particle vibrates back and forth along the middle axis, and drives the surrounding particles to vibrate, and gradually expands to all directions. This is the sound wave, and the propagation of sound waves is not the direct displacement of the medium molecules. , but the expansion of energy in the form of fluctuations. The energy of the sound wave is gradually consumed with the distance of expansion, and finally the sound disappears. The continuous vibration of the tuning fork makes the surrounding air molecules form a continuous waveform of dense and alternating. The sound wave propagating in the air is a longitudinal wave , in a longitudinal wave, the vibration direction of the medium molecules is pa...
