Description

Fire extinguishing method and system based on outboard motor Technical Field The invention relates to the technical field of ship fire control, in particular to a fire extinguishing method and system based on an outboard engine. Background The outboard engine is a common portable propulsion power device for ships, has the characteristics of small volume, high power density and flexible deployment, and is usually only used as propulsion power for ship navigation. In the field of ship fire control, the portable fire extinguishing device for small ships (such as a yacht and a fishing boat) has two typical configurations, namely an independent power type fire pump, which needs to be provided with fuel oil/electric power, has the defects of heavy volume and insufficient power, and a multiplexing ship engine power type fire extinguishing device, wherein the engine power of an outboard ship engine is directly used as the only power source of the fire pump. The existing fire extinguishing device based on the outboard engine generally follows the flow of 'single power driving, water source pressurization and jet fire extinguishing', but has the following core problems in practical application that (1) the power is dependent on singleization, if the engine fails due to faults such as corrosion and insufficient fuel, the fire extinguishing system is directly paralyzed, (2) the power-water source adaptability is poor, the outboard engine is fixed in power and cannot dynamically match the pressure and flow of fire water flow according to the fire source scale (such as small fire/large fire scene), the situation of 'pressure surplus waste power' or 'pressure insufficient fire extinguishing inefficiency' is easy to occur, and (3) the non-power redundancy design is that a standby power position supplementing mechanism is lacked, and the reliability in emergency fire extinguishing is difficult to guarantee. The key of the problems is that the existing scheme directly multiplexes the power of the outboard motor into the fire extinguishing power, and a power enhancement and redundancy mechanism is not designed aiming at the fire scene, which is basically excessive dependence on a single power source, and is similar to the problem of single power deviation in the field of ship fire control.
