The fire suppression of ships is more difficult than the fire suppression of land, and has become a very important concern for fire departments in various countries around the world. Particularly, when a fire disaster occurs on a ship sailing on the sea, the fire extinguishing assistance of other ships is not easy to obtain, and even if the adjacent ships exist, the adjacent ships are difficult to approach due to the sudden wind and waves or the fire roasting. The fire disaster of the ship is difficult to spread due to narrow space, narrow passage, dense goods and difficult personnel dredging, so that the fire disaster of the ship is easy to cause extremely serious consequences, and serious casualties and property loss are caused.
The ship fire-fighting system is a protection facility designed and installed for preventing ship fire, and consists of fire extinguishing medium, medium supply equipment, medium transmission pipeline, control valve and terminal equipment.
At present, fire extinguishing media of ships are mainly seawater, and a large amount of water is needed in a short time when the ships are used for fire fighting, so that the fire fighting water taking mode of the ships is to directly absorb water from the ocean through a fire fighting water absorption pipe. The fire-fighting water suction pipe is usually designed below the sea surface, marine organisms are often attached to the fire-fighting water suction pipe below the sea surface for a long time, the marine organisms attach and grow in the fire-fighting water suction pipe, the effective diameter of the fire-fighting water suction pipe can be reduced, the fire-fighting water flow is reduced, the fire-extinguishing efficiency is reduced, and meanwhile, faults are easily caused to fire-fighting water suction equipment. Particularly, when the fire-fighting suction pipe absorbs water, the fire-fighting suction pipe is easy to be blocked, and the fire extinguishment of the ship is influenced, because the offshore and the inland are often polluted by garbage and the marine culture is greatly developed.
