Ejection fire extinguisher of jet motor

Abstract

The invention provides a powerful multifunctional jet engine ejection fire extinction device which mainly comprises a fire fighting carrier platform with an extinguishing agent, a rotating device, a lifting device, a pitch device, and a fire extinction device on which a jet engine and an ejector nozzle are mounted; and a vehicle or a boat can be taken as the carrier platform. The device is characterized in that the rotating device, the lifting device and the pitch device are arranged on the fire fighting carrier platform with the extinguishing agent; the pitch device is connected with the fire extinction device, on which the jet engine and the ejector nozzle are mounted; and a fire extinguisher agent spout and a fuel aerosol spout are arranged in the ejector nozzle of the fire extinction device on which the jet engine and the ejector nozzle are mounted. When the fire fighting carrier platform with the extinguishing agent is in operation, the nozzle outlet of the fire extinction device, on which the jet engine and the ejector nozzle are mounted, is accelerated backwards by reverse thrust; fire extinction can be achieved by using the high speed fuel gas ejected by the jet engine to eject and atomize water, foam, solid powder particles and other fire extinguisher agents; the lifting device is used for raising the height of the fire extinction device, on which the jet engine and the ejector nozzle are mounted, thereby further increasing the spraying height and the spraying range; and the fuel aerosol spout has the ability of producing a smoke barrier and a fog barrier, thereby facilitating interference disguise. Moreover, the invention has a plurality of other functions including washing and disinfecting, smoke discharging, cleaning, snow removing, deicing and the like.

Problems solved by technology

[0002] According to the statistics of the International Fire Protection Association, due to the defects of existing fire extinguishing equipment, 60% of fires in oil depots, chemical plants, aircraft, oil tankers, tunnels, nuclear power plants, etc. cannot be effectively controlled immediately, causing casualties and property losses

At present, the jet engine of human utility model is the internal combustion engine with the largest power and the highest unit power-to-weight ratio, which is much higher than other internal combustion engines such as gasoline engines and diesel engines. Therefore, using its huge power as a fire-fighting tool to extinguish large-scale fires has the advantages that traditional fire-extinguishing equipment does not have. At present, jet engines are also used as power sources at home and abroad to extinguish fires, but foreign countries generally use open air and water exchange methods without ejection nozzle constraints, and their disadvantages are: the rate of fire is 20-30m / s The water jet and the high-speed gas jet with a firing rate of 450-550m / s directly collide with the high-speed gas jet in the atmosphere without constraints for kinetic energy exchange. This energy impact exchange method without constraints makes the energy of the gas and water jets insufficient exchange

However, because there are too many nozzles in the pipe, the resistance is large, the interference is large, the flow rate of the gas jet is reduced, and the kinetic energy is reduced, which prevents the further improvement of the rate of fire of the ejected water in the pipe. Height restriction, spray distance is still limited
