Anti-sinking and anti-overturning safety device for ship

Abstract

The invention discloses an anti-sinking and anti-overturning safety device for a ship. The device comprises a ship inner cavity and a protective outer shell. A protective structure is fixedly connected to the bottom end of the ship inner cavity, the protective outer shell is arranged at the bottom end of the ship inner cavity, the protective outer shell and the ship inner cavity are fixedly connected through the protective structure, anti-sinking mechanisms are fixedly connected to the two sides of the protective outer shell, and buoyancy foam plates are fixedly connected to the bottom ends ofthe anti-sinking mechanisms. The protective structure is arranged at the bottom end of the inner cavity of the ship; when the ship body encounters a touch reef or other impacts, the protection effectcan be achieved and ship sinking caused by ship breakage is avoided; the protective structure plays a role in protection, the working principle of the protective structure is that elastic elements which are symmetrically distributed on the two sides of the protection plate body at equal intervals achieve the effect of protecting the inner cavity of the ship. When the ship is impacted by externalforce, the ship is damaged due to too large impact force instead of a particularly sharp object.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a safety device for preventing overturning of a ship. Background technique [0002] The ship anti-overturning safety device is a device that prevents the ship from capsizing during navigation. The weather at sea is changeable, and the ship will capsize due to wind and waves during navigation and cause casualties. However, an existing ship There are many problems or defects in the anti-overturn safety device: [0003] First, a traditional ship anti-overturning safety device adopts the method of installing liquid nitrogen inside the ship to prevent overturning. When the ship sinks and the water pressure rises to a certain standard, the sliding sheet is pressed and the thimble is pushed to break. The liquid nitrogen tank releases liquid nitrogen to freeze the seawater entering the cabin. As the seawater is frozen, the volume of the displaced water increases, and the ship can c...
