Air bag type anti-capsizing device for passenger ship

Abstract

The invention discloses an air bag type anti-capsizing device for a passenger ship. The air bag type anti-capsizing device comprises a trigger control unit. The trigger control unit comprises a MRU and a PLC, wherein real-time monitoring is conducted on the motion posture in the navigational state of the passenger ship through the MRU, and the PLC is used for acquiring monitoring data of the MRU in real time, conduct analysis and judgment whether the passenger ship has the capsizing risk or not on the monitoring data and controlling a gas generation device. Multiple driving devices are symmetrically distributed at the two sides of the passenger ship. Each driving device comprises a pneumatic cylinder, a rotating disc, an anti-capsizing rod and an safety air bag, wherein each pneumatic cylinder and the corresponding rotating disc are located in a driving groove in the side wall of the passenger ship, and each anti-capsizing rod and the corresponding safety air bag are located in an air bag groove in the side wall of the passenger ship. Each anti-capsizing rod is provided with a gas channel communicating with the corresponding safety air bag. The gas generation device comprises a chemical formula gas generation device and a CO<2> gas charging device. The gas outlet end of the chemical formula gas generation device and the gas outlet end of the CO<2> gas charging device are connected with the gas channels. By means of the air bag type anti-capsizing device, the anti-capsizing rods can be driven within a short time to inflate the safety air bags, so that the safety air bags expand; stability of the passenger ship is effectively resumed; and the capsizing risk of the passenger ship is avoided.

Description

technical field [0001] The invention relates to an airbag-type anti-overturning device for a passenger ship, in particular to an airbag-type anti-overturning device for a passenger ship. Background technique [0002] According to the relevant regulations of IMO, when the instantaneous inclination angle of a passenger ship exceeds 30°, or the average inclination angle within 3 minutes exceeds 20°, the ship is in a capsized state. [0003] With the development of my country's inland shipping and the gradual improvement of the ship transportation system, the passenger-roller transportation method has developed rapidly. Since 2010, the country has completed a total of 224 million waterway passenger trips, a year-on-year increase of 0.3%. However, due to the particularity of the structure of the ro-ro passenger ship, it is difficult to maintain the stability of the ship in severe weather. [0004] At present, in view of the problem of ship capsizing, the following measures are u...

AI Technical Summary

Problems solved by technology

The above devices and measures can improve the anti-rolling and anti-overturning performance of the ship to a certain extent, but there are the following defects: (1) The functions of each device are single and cannot be taken into account

(2) Each device has certain restrictions when exerting its respective performance

(3) The addition of the above devices will bring side effects to the normal navigation of the ship
