The high-lift jet fire engine has the phenomenon of high limitation in extinguishment of the outer facade of the high-rise building. The highest elevation jet fire truck designed at present has a height of 62 meters, and for fires above this height, effective fire suppression cannot be achieved.
The unmanned helicopter is lifted off by taking the fire-fighting water pipe, and can spray water or foam to the fire wall to extinguish the fire. Since the weight of the fire hose suspended by the unmanned helicopter increases with the increase of the height, the lifting height is also limited.
The top of the high-rise building is provided with a similar indoor spraying fire extinguishing device, and a spray head is arranged on the outer side of the top of the building, so that the spray head is opposite to the wall surface. After the spraying system is started, water sprayed out by the spray head flows downwards along the wall surface, and plays a role in controlling the fire on the outer vertical surface of the building to spread upwards to a certain extent. Because the water quantity of the spraying system is smaller, the alignment of the fire position is not easy, and the effect of extinguishing the fire cannot be achieved in many times.
