A lifting type seabed door device for ships

Abstract

The invention discloses a lift-type seabed door device for a ship, which relates to the technical field of ship engineering. The lift-type seabed door device for a ship includes a seawater tank, which is provided with a first blocking plate and a second blocking plate; a hull seawater suction pipe, Located between the first blocking plate and the second blocking plate, the hull seawater suction pipe is connected to the seawater main pipe; the lifting cylinder is connected to the inner top wall of the seawater tank through the first driving mechanism, and the side wall of the lifting cylinder is pierced with a seawater suction pipe. The seawater suction pipe and the seawater suction pipe; the bottom of the seawater tank is provided with a through hole; when the lifting cylinder extends out of the seawater tank, the seawater suction pipe is connected to the seawater suction pipe of the hull, and the seawater suction pipe is blocked by the second blocking plate; When the cylinder is retracted into the seawater tank, the seawater suction pipe is blocked by the first blocking plate, and the seawater suction pipe is docked and connected with the hull seawater suction pipe. The present invention avoids marine organisms, dirt and crushed ice during the process of extracting seawater, not only has a higher cleanliness of the extracted seawater, but also has a good water inflow effect.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to a ship lifting type seabed door device. Background technique [0002] Since all the equipment of the ship that needs seawater cooling, as well as the cooling fresh water of the main engine of the ship, seawater needs to be drawn from the seabed door for cooling, so as to ensure the normal operation of the equipment and the normal operation of the ship. Therefore, the seabed door is an important part of the ship. In order to extract seawater for cooling, all ships are equipped with more than two seabed doors on the bottom plate at present. The seabed door is fixedly installed on the hull, and a grille is installed at the bottom, so that the seawater main pipe can draw seawater through the seabed door. [0003] After the existing seabed door works for a long time, more sea organisms and dirt will be attached, and various sea organisms and dirt will also be attached to the...

AI Technical Summary

Problems solved by technology

[0003] After the existing seabed door works for a long time, more sea organisms and dirt will be attached, and various sea organisms and dirt will also be attached to the surface of the hull plate around the seabed door, which not only makes the inhaled seawater cleanliness It is not high, which will affect the effect of water intake, and sea creatures may enter the filter of the seawater main pipe with the seawater, making it difficult to clean the bottom grille and filter of the seabed door

Therefore, the crew needs to check the seabed door regularly, and the maintenance workload is relatively large

In addition, when the ship sails in the polar sea area with crushed ice, the crushed ice may block the seabed door along the outer plate of the hull, thereby affecting the effect of water ingress
