Bracket type pneumatic fire-extinguishing cannon

Abstract

The invention discloses a hand extinguishing device, for solving the defects of present technique of air-powered fire-extinguishing cannon which only can be supported with should and has complex structure, small pressure and limited application area. The invention provides a trestle type air-powered fire extinguishing cannon comprising: a barrel; a firing mechanism mounted in the center of barrel; a high-pressure tank connected to the inner cavity of barrel; a cannon lens and a angle-measuring instrument mounted on the barrel; a exhaust valve mounted on the lower part of barrel; a barbette with a pestle; and a device formed by adjustable trestle and connected to the barrel to support the barrel. The invention utilizes the compressed gas as power, while it has the advantages as safety, reliability, simple structure, high working pressure, long shoot range, wide application range, flexible operation and high hit ratio.

Description

technical field [0001] The invention relates to fire-fighting equipment, which is a manual fire-extinguishing device with a compressed gas cylinder. Background technique [0002] With the rapid development of the national economy, fire protection work is more important, especially the rapid construction of high-rise buildings and large-scale industrial, commercial, cultural and sports facilities, which put forward higher requirements for fire protection equipment. Traditional fire hydrants and fire extinguishing equipment are suitable for short-distance fire extinguishing. For farther and higher fire areas, and fire areas where dangerous goods may explode, it is difficult for firefighters to approach, which requires long-distance fire-fighting equipment and fire extinguishing cannons. So came into being. CN2183551Y discloses a fire-fighting device of a "rocket fire extinguishing bomb". Although it has a long range of action and can fly to a far higher fire zone, its rocket ...

Problems solved by technology

CN2183551Y discloses a fire-fighting device of a "rocket fire extinguishing bomb". Although it has a long range of action and can fly to a far higher fire zone, its rocket motor needs gunpowder as power, which belongs to "fire products". There are high requirements for transportation and launch, not only the hidden danger of recurring danger, but also expensive

Although it is flexible and has a long launch distance, it still has the following disadvantages: 1. It can only be carried by the shoulders, and it is inconvenient to erect; 2. In order to reduce the recoil force on the human body, it is necessary to add a retreat cylinder containing multi-stage buffer springs. , so that the structure is more complicated; 3. Due to the limitation of human body capacity, the working pressure cannot be too large, so the scope of application is limited
