Ship broadside floating-assisting air bag

The utility model relates to the technical field of ships, in particular to a ship broadside floating-assisting air bag which comprises a ship body, a plurality of installation frames are fixedly installed at the two ends of the ship body through bolts, fixing frames are movably installed on the outer sides of the installation frames, and air bag bodies are arranged on the inner sides of the fixing frames. By arranging the water wetting switch, when the ship encounters large external force and generates a large inclination angle in the sailing process, water enters the water inlet in the inclined side of the ship body, after the water wets the water wetting switch, the water wetting switch controls the electric control valve to be started immediately, and after the electric control valve is started, an internal channel is opened; when the ship body is inclined, carbon dioxide gas can be quickly sprayed out from the gas nozzles, enters the telescopic pipeline along the inner pipeline and then inflates the airb
