Ship anti-flow-backward drainage system

Abstract

The invention discloses a ship anti-flow-backward drainage system. The system comprises a middle drainage pipe, an anti-wave valve arranged at the lower end of the middle drainage pipe and a self-closing water draining device arranged at the upper end of the middle drainage pipe, the middle drainage pipe is selectively communicated with the exterior of a cabin to be drained through the anti-wave valve, the end, away from the middle drainage pipe, of the self-closing water draining device is connected with an accumulated water deck of the cabin to be drained, the self-closing water draining device drains seawater from the cabin to be drained into the middle drainage pipe, and seawater inside the middle drainage pipe is isolated from the accumulated water deck. Seawater flow backward can beeffectively avoided, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship anti-drainage system. Background technique [0002] The ro-ro passenger ship is a kind of passenger ship, which can not only carry passengers, transport various vehicles, but also provide accommodation and entertainment places for passengers. Ro-passenger ships generally have one or more flat decks above the engine room as cargo decks to facilitate the placement of cargo units. In order to facilitate vehicle side passage, ramps or lifting platforms are provided between the cargo decks to communicate with each other. One or more decks are arranged above the cargo deck to arrange passenger living quarters or other passenger activity fields. [0003] Due to its unique hull structure and convenient and fast loading and unloading advantages, ro-ro passenger ships can bring convenient and fast services to people. With the development of logistics and tourism, ro-ro passenger ship...

AI Technical Summary

Problems solved by technology

[0004] At present, the drainage system of the garage compartment of the ro-ro passenger ship is unreasonably designed and has low reliability. When the ship collides or hits a rock and other accidents cause partial damage to the hull, the drainage system of the garage compartment is also destroyed, thereby increasing the safety of the passenger rovers.
