The invention discloses a lifesaving
system for a passenger ship. The lifesaving
system comprises compressed airbags, a central controller, an angle sensor and an alarming device, wherein the compressed airbags are stored in concave
airbag mounting grooves in freeboards of a ship body, are connected with the ship body through
airbag fixing surfaces and connecting mechanisms, are connected with
compressed air tanks through pipelines, and are provided with air vent valves; the angle sensor is mounted at the middle position of a navigation bridge; the central controller is connected with the angle sensor, the alarming device, the
compressed air tanks and the compressed airbags respectively, and is used for receiving a
signal from the alarming device, controlling the
compressed air tanks to be opened to supply air to the compressed air bags and discharging air of the compressed airbags for storage. The lifesaving
system for the passenger ship can automatically give an alarm and can be started under an extreme climatic condition, so that stability of the passenger ship is enhanced; the lifesaving system is easy to
mount and construct, has no special requirements on an existing
design standard, and can be conveniently additionally mounted on an existing passenger ship.
