Description

Building outer wall fire control cooling fire extinguishing device based on roof water storage facility Technical Field The invention relates to the technical field of building fire protection, in particular to fire protection equipment for realizing cooling and fire extinguishing of building outer wall fire by adding a special water spraying and wetting device by using the existing water storage facilities on the roof as a water source. Background Along with the acceleration of the urban process, the number of high-rise buildings is increased, and the external wall fire disaster becomes a great difficulty in urban fire fighting due to the rapid spreading speed, high extinguishing difficulty and high safety risk. The existing high-rise building outer wall fire-fighting technology mainly has the defects that firstly, a special fire-fighting device needs to independently construct a water storage facility and a water supply network, a base, a water tank and a traction mechanism are additionally arranged on the high-rise auxiliary fire-fighting device disclosed by CN113813525A, the construction cost is high, the occupied space is large, secondly, external rescue equipment such as a fire-fighting lifting vehicle is depended on, the high-rise building is obviously limited by the height of the building, effective coverage is difficult to realize for an ultra-high-rise building, the response time is long, thirdly, a part of the existing outer wall fire-fighting device such as CN220213771U adopts a fixed water diversion pipeline design, the suitability is poor, fire spread in different areas cannot be flexibly dealt with, and fourthly, high-end equipment such as an intelligent fire-fighting robot, such as a wall climbing and window-drilling fire-fighting robot, is complex in structure, the maintenance cost is high, and popularization and application in common buildings are difficult.
