A passenger ship lifesaving system

Abstract

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.

Description

technical field [0001] The invention relates to a passenger ship lifesaving system, in particular to the arrangement of compressed air bags. Background technique [0002] Generally, ocean passenger ships have relatively high freeboard, and the safety requirements for anti-sinking, fire prevention, and lifesaving are also relatively strict. However, the climate at sea is complicated, and strong winds and waves often occur, which pose a threat to sailing passenger ships. The main structure of inland passenger ships is thin, and the superstructures usually extend to the bow and stern and protrude outboard to increase the passenger carrying area. Due to draft restrictions and contingency requirements of the voyage, inland river passenger ships have shallower drafts and lower freeboards, and their ability to resist wind and waves is poor. Therefore, encountering reasons such as relatively large wind and waves and improper human operation may cause passenger ships to capsize aft...

AI Technical Summary

Problems solved by technology

However, the above-mentioned airbag device has the disadvantages of slow emergency response, time-consuming inflation and low degree of automation. It cannot predict dangerous sea conditions in time and automatically activate the emergency device. When a sudden sea situation occurs, it cannot immediately avoid ship distress.
