Aerodynamic fire monitor

Abstract

The invention discloses an aerodynamic fire monitor which comprises a monitor barrel, a support and a base, wherein the monitor barrel comprises an outer cylinder; an inner cylinder is arranged in the outer cylinder; both the inner cylinder and the outer cylinder are of cylindrical cavity structures; a sealed air chamber is arranged between the outer cylinder and the inner cylinder; a first air inlet for communicating the air chamber with the outside is formed in the rear end of the air chamber; a second air inlet for communicating the air chamber with the outside is formed in the front end of the air chamber; an annular piston around the inner cylinder is arranged in the air chamber; an air channel is arranged on the wall of the inner cylinder positioned between the first air inlet and the annular piston; a push plate is arranged in the inner cylinder; a fire bomb is arranged on the push plate; the front end of the bottom of the push plate and the annular piston are fixedly connected by a connecting rod; the connecting rod can freely move along a slideway at the lower end of the inner cylinder; a sealing cover is arranged at the rear end of the push plate; and a pneumatic valve which serves as an arming mechanism and communicates with the air chamber is arranged in the middle of the monitor barrel. According to the aerodynamic fire monitor disclosed by the invention, the loading, the arming and the unloading processes can be realized by using high-pressure and low-pressure gases; and the aerodynamic fire monitor is convenient for handling, simple in operation and suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a fire-fighting appliance, in particular to a pneumatic fire-fighting monitor specially aimed at fires in domestic medium and large high-rise buildings. Background technique [0002] Inexpensive fire extinguishers, as loyal guards to eliminate initial fires, have been widely used in our country, and they also play an important role in ensuring the fire safety of high-rise civil buildings. However, in dealing with high-rise large-scale fires, it is difficult for fire extinguishers to play their role. Due to high-rise fires and safety issues, it is difficult for firefighters to carry out fire-fighting work in the fire-fighting floor. In order to ensure safety, fire-fighting outside the floor is the key. At present, there are many fire extinguishing products on the market, which can be roughly divided into five categories: traditional fire extinguishers, fire extinguishing agents, fire blankets, high-pressure water guns, and fire ...
