Sound wave fire extinguishing device capable of automatically adjusting power

Abstract

The invention provides a sound wave fire extinguishing device capable of automatically adjusting power. The sound wave fire extinguishing device is characterized by comprising a main control module, apower amplification module, a loudspeaker, an acoustic cavity, a mechanical arm module, a steering engine driving module, a far infrared flame sensor, an angular displacement sensor and a distance measuring module, wherein the main control module is used for generating sine wave analog electric signals with specific frequency and amplitude; the power amplification module is used for amplifying the sine wave analog electric signal to generate a heavy-current low-frequency sound wave electric signal to drive a loudspeaker; the loudspeaker is used for playing the low-frequency sound wave electric signal; the acoustic cavity is used for gathering low-frequency sound waves; the mechanical arm module is used for realizing three-dimensional rotation of the acoustic cavity; the steering engine driving module is used for driving each joint of the mechanical arm to move; the far infrared flame sensor is used for detecting the fire behavior; the angular displacement sensor is used for monitoringthe displacement and the angle of a mechanical arm; and the distance measuring module is used for detecting the distance between a combustible material and the acoustic cavity. According to the soundwave fire extinguishing device, aiming at the defects that in the prior art, three-dimensional rotation cannot be performed in any direction, power cannot be automatically adjusted, and a fire sourcecannot be directionally aimed at for effective fire extinguishing, the output power is automatically adjusted according to the fire situation, and flame is aimed at for effective fire extinguishing.

Description

Technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a sound wave fire extinguishing device with automatic power adjustment. Background technique [0002] With the continuous progress of human civilization, the incidence of fire remains high every year. According to incomplete statistics, more than 10,000 fires occur every day in the world, causing hundreds of deaths. In recent years, there have been about 40,000 fires in my country each year, with more than 2,000 deaths and 3,000-4,000 disabled people. The annual direct property loss caused by fires is as high as more than 2 billion yuan, of which the death toll from family fires accounts for the total death toll. More than 60%, the main reason is that most households are not equipped with fire extinguishing equipment, or the fire fighting methods are wrong, so that the combustion can not be suppressed in the early stage, which leads to large-scale fires.

Problems solved by technology

[0011] Aiming at the deficiencies existing in the prior art, such as the inability to perform three-dimensional rotation in any direction, the inability to automatically adjust the power, and the inability to orientate and aim at the fire source for effective fire extinguishing, the present invention provides a sonic fire extinguishing device with automatic power adjustment. According to the situation, use the data collected by the far-infrared flame sensor to judge the range of the data value to know the size of the fire, automatically output the corresponding power in three levels of low 30W, medium 40W, and high 60W, and aim at the flame to effectively extinguish the fire
