WATER INLET STRUCTURE FOR SEA CHEST OF POLAR NAVIGATION SHIP

摘要

Disclosed is a water inlet structure for a sea chest of a polar navigation ship. The structure comprises a hull outer plate (1), wherein the hull outer plate (1) is provided with a seawater reservoir (2); the seawater reservoir (2) and the hull outer plate (1) form an integrally formed part; several grid-type slots (3) are provided, at a position corresponding to the seawater reservoir (2), in the hull outer plate (1); the seawater reservoir (2) is in communication with the outside of the hull outer plate (1) by means of the grid-type slots (3); and one end, away from the grid-type slots (3), of the seawater reservoir (2) is provided with a seawater outlet. Directly arranging the grid-type slots (3) in the hull outer plate (1) can not only ensure that debris and large marine organisms do not enter the sea chest, but also effectively prevent broken ice from entering the sea chest when seawater enters the seawater reservoir (2) of the sea chest structure through the grid-type slots (3).
