Remote-control elevating stereoscopic fire-extinguishing device

Abstract

The invention discloses a remote-control elevating stereoscopic fire-extinguishing device. By taking a fire truck as a carrier, a combined elevating cantilever crane and a landing leg mechanism are arranged, wherein the top end, the middle part and the bottom part of the cantilever crane are respectively provided with a first fire monitor, a second fire monitor and a third fire monitor; the cantilever crane is provided with a delivery pipe used for delivering fire-extinguishing chemicals to the three fire monitors; lift power is provided for the cantilever crane by a hydraulic system on the fire truck; and the first fire monitor, the second fire monitor and the third monitor are remotely controlled by a remote-control device on the fire truck. According to the novel, remote-control elevating stereoscopic fire-extinguishing device disclosed by the invention, remote-control and close-range stereoscopic fire fighting can be realized, and at the early period of a fire, the fire behavior can be effectively controlled, the fire-extinguishing efficiency can be increased, the fire-extinguishing chemical loss can be reduced, and the safety of fire personnel can be effectively ensured. The novel remote-control elevating stereoscopic fire-extinguishing device can be used for specially putting out large fires caused by oil tank accidents, light dydrocarbon tank accidents, well blowout and chemical unit accidents.

Description

Technical field: [0001] The invention relates to a remote control lifting three-dimensional fire extinguishing device. Background technique: [0002] Petrochemical production equipment is tall and dense in a three-dimensional arrangement, and the pipelines are criss-crossed and closely connected. Petrochemical products have two different forms of gas and liquid. Petrochemical fires have extremely fast fire spread, three-dimensional high-temperature combustion, continuous explosion, and the diffusion of toxic and harmful gases. Wide range and other characteristics, this type of fire will cause chemical equipment to be damaged to varying degrees when it explodes, and the flammable medium will burn in the form of open or oblique spray at the damaged part. When the chemical oil flows out from the damaged part, It will form three-dimensional combustion on the ground (including trenches), low altitude and high altitude. The current firefighting method is to use guns (cannons) to ...

Problems solved by technology

In this way, the favorable fire extinguishing opportunity of low oil temperature in the early stage of the fire is lost, which makes it necessary to invest more manpower and material resources in the later stage of fire extinguishing. Taking the fire of an oil tank with a diameter of tens of meters as an example, it is necessary to invest dozens of vehicles or even hundreds of vehicles. Hundreds of fire-fighting vehicles require dozens of tons of fire-extinguishing agents, and the fire-fighting site is narrow and the economic investment is large; the second is to prolong the fire-fighting cycle, which also increases the economic loss of the fire

[0006] Existing fire-fighting vehicles cannot get close to the danger source and put out fires at close range when fighting large-scale petrochemical fires. According to the fire-fighting experiments of 50,000-square-meter oil tanks done in the past, spraying fire from 80 meters to 100 meters into a tank with a height of 20 meters Because the foam fire extinguishing agent is very light, under the action of wind and fire source, the foam fire extinguishing agent that enters the top of the tank to extinguish the open fire can reach 40% at most, and it is impossible to cool the combustion device at the same time on one device and cannot extinguish the ground. Flowing fire has little fire extinguishing efficiency, which is also the main reason why many chemical plant fires cannot be extinguished in time
