Abstract

The invention discloses a backflow-prevention drainage structure for a ship. The backflow-prevention drainage structure comprises water collecting tanks, drainage pipes and backflow-prevention devices, wherein the water collecting tanks are correspondingly arranged on the lower sides of decks, through holes are formed in the portions, corresponding to the water collecting tanks, of the decks, andthe drainage pipes are communicated with the water collecting tanks; the backflow-prevention devices are arranged in the water collecting tanks and correspond to the drainage pipes. By arranging the water collecting tanks on the lower sides of the decks of the ship and connecting the drainage pipes with the water collecting tanks, sewage, wastewater and the like on the ship can be easily uniformlycollected and discharged; secondly, the water collecting tanks can effectively protect the backflow-prevention devices, the backflow-prevention devices are prevented from being damaged by external acting force, and the situation that the backflow-prevention devices cannot work when a cabin is bilged is avoided; by arranging the backflow-prevention devices in the portions, corresponding to the drainage pipes, of the water collecting tanks, the situation that when the ship cabin is bilged, inflowing water flows backwards into other cabins through a drainage system can be effectively prevented,the problem that the drainage system affects the damaged stability is solved, the stability of the ship is effectively improved, and the safety of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of ship structures, in particular to a ship anti-drainage structure. Background technique [0002] The design of the existing ship drainage system is divided into the drainage system of the open deck and the drainage system of the cabin. The open-air drainage system is generally designed in the form of leaks; the cabin drainage system generally adopts a combination of leaks and pipes directly welded to the deck. [0003] However, the current ship drainage system design is generally an open system. The so-called open system means that the whole system is not an internally closed system. When a ship has a flooding accident, the water can enter other compartments through the drainage system, destroying the stability of the ship and failing to meet the specification requirements. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an anti-backflow and drai...
