Problems solved by technology

However, when the ship is in the polar low temperature environment, a large amount of floating ice is distributed around the hull. If no special measures are taken, the inlet of the seawater pump in the seabed door will be easily blocked by sea ice, and the seawater pump will not be able to suck in sufficient seawater, which will lead to a shortage of main engines. The cooling water supply overheated, causing the ship to stop

Abstract

The anti-icing sea chest device comprises a seawater tank, a water inlet grating, a cooling water reinjection pipe, a seawater pump suction pipe and a baffle, the seawater tank is divided into an ice collection area on the upper portion and a water inlet area and a water drainage area on the lower portion, and the baffle is fixedly arranged in the seawater tank. The baffle is used for separating a water inlet area and a water outlet area of the seawater tank, the water inlet grating is arranged on a ship body outer plate of the seawater tank water inlet area, an inlet of the seawater pump suction pipe is connected with the seawater tank water outlet area, and an outlet of the cooling water reinjection pipe is connected with the seawater tank ice collecting area. The sea chest device is simple in structure, floating ice at an inlet of a sea water pump can be effectively removed, and a pipeline system in a ship body is prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of polar navigation ships, in particular to an anti-ice seabed door device suitable for polar ships. Background technique [0002] In recent years, the global climate has gradually warmed, and the ice in the Arctic region has gradually melted, making the Arctic route gradually feasible. The development of polar sailing ships has gradually become a hot spot. Polar ships need to be specially designed for the ice environment in order to have Comprehensive anti-icing and anti-freezing ability. [0003] In the prior art, ships usually need to open holes in the hull plate and arrange seabed doors to inhale seawater for the cooling, ballasting and fire fighting systems of the main engine on board. Generally, the seawater pump suction port of a ship is directly arranged in the seabed door, and the seawater pump directly sucks seawater into the ballast, cooling and fire-fighting piping systems on the ship. However,...
