Underground deep pit cable tunnel moving gas fire-extinguishing equipment

Abstract

The invention provides underground deep pit cable tunnel moving gas fire-extinguishing equipment which comprises two metal guide rails, a moving gas fire-extinguishing device and a driving power controller, wherein the moving gas fire-extinguishing device comprises a mounting platform, a gas fire-extinguishing mechanism, a reciprocating advance driving mechanism and a camera shooting mechanism; the gas fire-extinguishing mechanism is mounted on the mounting platform and is used for injecting a gaseous extinguishing agent to put out a fire; the reciprocating advance driving mechanism is used for driving the mounting platform to reciprocate on the metal guide rails; the camera shooting mechanism comprises a camera shooting component and a monitoring display; the camera shooting component isused for shooting cable operating images of a target area of two side walls of the tunnel and transmitting the images to the monitoring display; and the monitoring display is used for supplying powerto the camera shooting component and displaying images shot by the shooting component in real time. According to the equipment disclosed by the invention, the fire behavior occurring in the underground deep pit cable tunnel can be rapidly and effectively extinguished at the fixed point, lots of fire-extinguishing agents can be saved, and any dead angle does not exist in the fire-extinguishing process.

Description

technical field [0001] The invention relates to the technical field of fire protection and fire safety, in particular to a mobile gas fire extinguishing equipment for an underground deep pit cable tunnel. Background technique [0002] In recent years, my country's urban infrastructure has rapidly developed underground. In many cities, power supply cables are arranged in rows in deep underground tunnels with a depth of more than 50 to 60 meters. The length of these tunnels can reach several kilometers or even more than ten kilometers. Although A dry powder fire extinguishing device is arranged, but due to the harsh and high-humidity environment of the underground deep pit cable tunnel, the validity period of the fire extinguishing agent and the fire protection period of the fire extinguishing device replaced once are greatly shortened, and the fire extinguishing agent in the fire extinguishing device replaced once It will fail within 2 to 3 years or even in a shorter time. In o...

[0002] In recent years, my country's urban infrastructure has rapidly developed underground. In many cities, power supply cables are arranged in rows in deep underground tunnels with a depth of more than 50 to 60 meters. The length of these tunnels can reach several kilometers or even more than ten kilometers. Although A dry powder fire extinguishing device is arranged, but due to the harsh and high-humidity environment of the underground deep pit cable tunnel, the validity period of the fire extinguishing agent and the fire protection period of the fire extinguishing device replaced once are greatly shortened, and the fire extinguishing agent in the fire extinguishing device replaced once It will fail within 2 to 3 years or even in a shorter time. In order to achieve the purpose of effectively preventing the cables in the underground deep pit cable tunnel, it is necessary to frequently replace the new fire extinguishing agent storage tank, which not only increases the labor intensity of maintenance personnel, but also brings unnecessary economic costs. loss, and the dumping of invalid fire extinguishing agents causes environmental pollution, and the high humidity environment is also likely to cause serious corrosion of fire extinguishing devices
