Suspended type automatic fire extinguishing device for high-rise building

Abstract

The invention discloses a suspended type automatic fire extinguishing device for a high-rise building. The suspended type automatic fire extinguishing device comprises a fire control cabin, an ammunition feed system, a launching system and a plane self-balance device. The fire control cabin comprises an aluminum section frame, large universal wheels and a propulsion propeller. The ammunition feed system comprises a magazine, an ammunition drum, a support, an ammunition drum outer box, a groove wheel driving wheel, a groove wheel driven wheel and a servo motor. The launching system comprises a launching gun barrel, an air cylinder, a connecting rod, a first servo motor, a buckle, a plane cam, an impact pressing block, a propulsion seat, an energy storage spring, a linear guide rail and a lead screw nut. The plane self-balance device comprises a vertical transmission mechanism and a transverse transmission mechanism. The transverse transmission mechanism is composed of a balance block, a lead screw nut, a lead screw, a linear guide shaft, a center shaft and a second servo motor. The suspended type automatic fire extinguishing device is simple in structure, safe, reliable and high in automation degree, and the problem that the fire protection firing range of a ground fire extinguishing system to the high-rise building is insufficient is solved; and a mechanical launching device is adopted, so that safety is enhanced, and the fire protection bottleneck of the high-rise building is broken through.

Description

technical field [0001] The invention relates to the field of fire engineering, in particular to a suspension type automatic fire extinguishing device for high-rise buildings. Background technique [0002] With the continuous acceleration of the urbanization process, urban buildings are gradually developing towards high-rise buildings. However, the frequency of fire accidents in high-rise buildings is also increasing. Since the current climbing fire truck can only reach a maximum of 50m, it is difficult for the existing traditional ground fire fighting equipment such as fire trucks, aerial ladders and fire monitors to deal with fire accidents at higher floors. At present, ground long-distance pneumatic fire extinguishing guns have become a hot spot in the research of fire-fighting equipment. The latest domestic research achievement is the "missile fire extinguishing system" of the high-rise building fire extinguishing system of the Second Academy of Aerospace Science and Indu...

Problems solved by technology

In order to achieve a large range, the current methods of launching fire extinguishing bombs mostly use pneumatic or gunpowder chemical energy acceleration methods. However, in the case of close-range fire extinguishing at the fire scene, these two methods have shown their limitations in terms of safety.
