Background
At present, the fire extinguishing modes of ships mainly comprise the following two modes: 1. a carbon dioxide fire extinguishing system: the carbon dioxide gas cylinder, the pipeline and the valve which are mutually connected are arranged on the ship, and when a fire breaks out, the valve is opened to release carbon dioxide to the cabin or the storage battery cabin to extinguish the fire; 2. pressure water smoke fire extinguishing systems: the ship is provided with a pressure water tank, a pump set, a pipeline and valve pieces which are connected with each other, when a fire breaks out, the valve pieces are opened, and the fire can be extinguished by manually or automatically spraying.
However, the specific gravity of the carbon dioxide is high, the carbon dioxide gas cylinder is heavy, the navigation speed of the ship is influenced, and the carbon dioxide is easy to sink to the bottom of the cabin during fire extinguishing, so that the top of the cabin cannot be completely extinguished; the pressure water mist fire extinguishing system is complex in structure, heavy in weight, high in cost and large in occupied space, influences the ship speed, and is used for extinguishing fire in the storage battery compartment to cause the storage battery to be scrapped completely. A fire extinguishing system for ships that extinguishes fire using carbon dioxide or water mist is proposed in the prior publication No. CN211097167U, but the fire extinguishing range of carbon dioxide is small, and the water mist extinguishes fire, which results in the rejection of storage batteries, and the reliability is low. If a ship fire extinguishing system which is simple in structure, small in weight, small in occupied space, wide in fire extinguishing range and capable of avoiding scrapping of a storage battery can be designed, the problem can be well solved.
