Abstract

The invention specifically relates to an anti-sinking system for a ship. The anti-sinking system for the ship comprises a buoyancy device arranged in a watertight compartment under a deck and is characterized in that the buoyancy device is formed by filling the watertight compartment by using flame-retardant polyurethane foam; the density of the flame-retardant polyurethane foam is less than that of the water; and the buoyancy generated by the flame-retardant polyurethane foam in the watertight compartment in the water is larger than the total weight of the ship. The anti-sinking system for the ship further comprises anti-collision structures arranged on ship sides of the ship; and the anti-collision structures comprise composite clamping plates which are used for manufacturing the ship sides, wherein the composite clamping plates comprise steel plates, which are arranged on two sides outside the clamping plates, and flame-retardant polyurethane foams, which are filled between the two steel plates. The invention aims at providing the anti-sinking system for the ship; and by using the anti-sinking system for the ship, the ship navigating safety is enhanced.

Description

technical field [0001] The invention relates to the field of ship manufacturing, in particular to a ship anti-sinking system. Background technique [0002] Ship is a kind of means of transportation at this stage, especially in the freight industry, because it can carry a large amount of goods, it is widely used in maritime transportation. At present, the basic structure of ships at home and abroad is to set the main part of the lower part and the superstructure part. The main part generally refers to the hollow body with a specific shape surrounded by the hull and the upper deck below the deck. A critical part of buoyancy, seakeeping performance and hull strength. [0003] Therefore, ship design mainly focuses on its safety performance, usually by enhancing the strength of the hull and reducing its quality to improve the safety performance of the ship. However, if there is an exception for the hull to enter the water, it will cause immeasurable damage. Therefore, how to a...
