Hatch door mechanism of ship

Abstract

The invention relates to a hatch cover device, in particular to a hatch door mechanism of a ship, which is easy to open and close. The hatch door mechanism comprises a hatch door, a hatch door frame and a hydraulic mechanism, wherein the hatch door is a plate-shaped structural member; the hatch door frame is used for supporting the hatch door, and is provided with an entrance and exit through which the hatch door is closed; the hydraulic mechanism is arranged between the hatch door and the hatch door frame; the hydraulic mechanism comprises a hydraulic cylinder and a piston rod which moves relative to the hydraulic cylinder, wherein an elastic protuberance is arranged on the piston rod, and the popping-up degree of the elastic protuberance is protruded out of the outer wall of the hydraulic cylinder; the middle part of the hatch door is made from flexible materials, and the area of the flexible materials is 60-70% of the total area of the hatch door. The invention provides the hatch door mechanism of the ship. The opening and the closing of the hatch door mechanism are completely mechanized, so that human resources are saved, and besides, the hatch door mechanism is safe; the flexible materials are used, so that when accidents occur and the hatch door falls down, screaks can be avoided, and ship crew or tourists cannot be injured.

Description

technical field [0001] The invention relates to a hatch cover device, in particular to a hatch mechanism of a ship which is easy to open and close. Background technique [0002] Generally speaking, the hatch is the general designation of the hatch and the manhole of the ship, especially for loading and unloading cargo or for people to come in and out on the open through portion on the deck. The size of the hatch should depend on the purpose of use. In order to ensure the strength and safety of the hull, the hatch should be as small as possible, but in order to improve the loading and unloading capacity, the larger the better. [0003] In order to prevent seawater from flowing into the ship, a hatch coaming of sufficient height is set around the hatch and the hatch covering the top is called a hatch cover. [0004] In the hatch covers of the prior art, it is easy to hit the crew or tourists when the hatch cover falls in danger, and it is inconvenient to open. The hatch cover...

AI Technical Summary

Problems solved by technology

[0004] In the hatch covers of the prior art, it is easy to hit the crew or tourists when the hatch cover falls in danger, and it is inconvenient to open. The hatch cover is opened and closed manually by people, and the hatch cover is usually set at Therefore, it is very inconvenient to open and close with the help of a ladder or a long pole

[0005] In addition, due to the heavy weight of the metal hatch cover, it is easy to cause a pinch accident when it is opened, and it will hurt people when it falls
