The invention discloses a large-range fire extinguishing bomb carried by an unmanned aerial vehicle and a using method thereof, the large-range fire extinguishing bomb comprises an unmanned aerial vehicle and a fire extinguishing bomb device, and the top of the fire extinguishing bomb comprises a filling valve, a heating device, a liquid storage tank, a sealing gasket, a constant-pressure shearing piece and a release pipe. When the unmanned aerial vehicle arrives at a designated position, the heating device is used for generating heat, liquid carbon dioxide is instantly vaporized, the volume is expanded by about 600 times, the pressure is sharply increased, and when the pressure in the pipe reaches the ultimate strength of the constant-pressure shear blade, high-pressure gas breaks through the constant-pressure shear blade and is released from the release pipe, so that the purpose of extinguishing fire is achieved. The method is easy and convenient to operate, high in safety coefficient and large in fire extinguishing range.
本发明公开了一种无人机搭载的大范围灭火弹及其使用方法,包括无人机和灭火弹装置,所述灭火弹顶部包括充装阀、加热装置、储液罐、密封垫、定压剪切片、释放管。当无人机到达指定位置时,利用加热装置产生热量,使液态二氧化碳瞬间汽化,体积膨胀约600倍,压力急剧升高,当管内压力达到定压剪切片极限强度时,高压气体冲破定压剪切片从释放管释放,从而达到灭火的目的。该方法操作简便,安全系数高,且灭火范围较大。
