Multifunctional liquid nitrogen extinguishment vehicle for alley way

Abstract

The invention discloses a multi-functional lane liquid nitrogen fire extinguishing vehicle, which is fire fighting equipment, consists of a track chassis provided with rail wheels or automobile wheels, a liquid nitrogen storage, a normal temperature carburetor, a vacuum insulation pipe, a gas spraying hose, a direct current spotlight, a respiratory oxygen supply device and so on, and has no power system. The fire extinguishing vehicle adopts a method that liquid nitrogen is carburated and then forms refrigerated nitrogen to submerge a coal layer to reduce the temperature of the coal layer and cause the oxygen deficiency of the coal layer and a lane to extinguish fire according to physicochemical properties that the liquid nitrogen has ultra-low temperature, nitrogen is incombustible, and the fire extinguishing by the nitrogen has no smoke and smell and does not generate ozone, and can deeply enter the inside of the lane for flexible mobile operation under the traction of a coal mine locomotive or the pushing of manpower, so the fire extinguishing vehicle has the characteristics of simplified structure, complete function, large gas supply amount, flexibility and convenience when entering the lane for fire extinguishing operation, environmental-friendly fire extinguishment, energy-saving fire extinguishment, instantly-effective fire extinguishment and so on, is applicable to the fire extinguishment of coal mine lanes, and is also applicable to the fire extinguishment of other lanes or large occasions.

Description

Technical field: [0001] The invention relates to fire fighting equipment, in particular to a fire extinguishing vehicle used for roadway fire fighting. Background technique: [0002] In coal mining, large-scale coal seam fire accidents caused by gas gas occur from time to time, and each mine fire accident has caused huge losses to national resources and people's lives and properties. Due to the particularity of the deep and long coal mine roadway, the existing vehicle-type fire extinguishing trucks are limited to go down the coal mine roadway because they contain combustible fuel or gas, and the chassis of the existing truck-type fire-fighting trucks are only equipped with gas tires, so it is difficult to get off. The coal mine roadway, which seems to be the same as the train track, plays a fire-extinguishing role; the existing fixed fire extinguishers cannot control the spread of large-area fires in the coal seam due to the limited storage of fire-extinguishing raw material...

AI Technical Summary

Problems solved by technology

Due to the particularity of the deep and long coal mine roadway, the existing vehicle-type fire extinguishing trucks are limited to go down the coal mine roadway because they contain combustible fuel or gas, and the chassis of the existing truck-type fire-fighting trucks are only equipped with gas tires, so it is difficult to get off. The coal mine roadway, which is similar to the train track, plays the role of fire extinguishing; the existing fixed fire extinguishers cannot control the spread of large-scale fire in the coal seam due to the limited storage of fire extinguishing materials

The patents of China's disclosed liquid nitrogen fire-fighting trucks have publication numbers CN2652437, CN1522773, CN2483034, etc. These fire-fighting trucks are not provided with rail wheels adapted to travel in the roadway, nor are lighting devices and breathing oxygen supply devices arranged. It does not have the function of fire extinguishing operation and safety guarantee function in the lower roadway; the fire extinguishing method commonly used at present is to close the roadway and let the coal seam burn naturally. Although the fire extinguishing method is effective, there are disadvantages such as long closed burning time, lifesaving in the closed area, burning a large amount of raw coal in the fire layer, burning out production facilities, and polluting the production environment.

In the actual combat of roadway fire fighting, unpredictable situations may occur at any time, such as roadway locomotive failure, track blockage, lighting interruption, casualties, rescue and rescue, especially in the case of casualties and survivors, it is impossible to close the roadway mouth to extinguish the fire. It is also impossible to choose. At this time, emergency rescue and lifesaving have become a pair of contradictions. Both of them are against the clock. The existing fire extinguishing equipment and technology are difficult to solve this pair of contradictions.
