Abstract

The invention discloses a manhole cover for a ship. The manhole cover comprises a base plate (2), a cover plate (4), a sealing part (3), a coaming (1), a plurality of locking bolts (11) and a hinge mechanism, wherein the cover plate (4), the sealing part (3), the coaming (1), the locking bolts (11) and the hinge mechanism are arranged on the base plate (2), the sealing part (3) is arranged between the base plate (2) and the cover plate (4), a through hole is formed in the base plate (2), the coaming (1) is arranged on the side surface, facing a enclosure bulkhead (12) of a cabin, of the base plate (2) and is arranged around the through hole, the cover plate (4) is connected with the base plate (2) through the locking bolts (11), and one side of the cover plate (4) is connected to the coaming (1) on the same side with the base plate (2) through the hinge mechanism. Through the hinge connecting mode of the cover plate and the base plate, not all nuts and locking bolts on the manhole cover need to be unscrewed, operation of the manhole cover is facilitated, and the work efficiency and the reliability are improved.

Description

technical field [0001] The invention relates to a manhole cover for ships. Background technique [0002] Ships are composed of many different types of cabins. These cabins have different purposes and functions, either to ensure the ship's anti-sinkability, or to load oil, water, or to load cargo. In order to be able to pass in and out of these cabins conveniently, manhole covers need to be set. [0003] Existing marine manhole covers all use bolts to press the cover plate on the seat plate, but all the nuts and locking bolts on the manhole cover need to be unscrewed during use, and then the cover plate can be opened to enter the cabin, so There are technical problems such as complicated operation and low work efficiency. Contents of the invention [0004] The present invention is proposed to overcome the above-mentioned defects in the prior art, and the technical problem to be solved is to provide a manhole cover for a ship, which facilitates the operation of the manhole...
