Naval vessel watertight door

Abstract

The invention discloses a naval vessel watertight door which comprises a door panel (1) and a door frame (2), wherein the door panel and the door frame are connected through a door hinge (3), a sealing rubber strip (4) is arranged on the periphery of the inner side of the door panel, a pressing knife (5) which can form sealing with the sealing rubber strip is arranged on the periphery of the outer side of the door frame, a pressing seat (6) which extends outwards is arranged on the periphery of the inner side of the door panel, a pressing lever (7) is arranged on the pressing seat, a sliding block (8) which can slide along the side direction of the door frame is arranged in the door frame, and a slope (9) is arranged on the sliding block. When the door is closed, the pressing lever is positioned at the bottom part of the slope, a positioning surface (10) is arranged at the top end of the slope, and an opening and closing maneuvering lever (11) which can drive the sliding block to slide and further move the pressing lever to the positioning surface along the slope is arranged on the door frame. The door panel and the door frame have the advantages of high strength, difficult deformation, good shock resistance, effort-saving and reliable opening and closing, good sealing property and very strong practicality and popularization value.

Description

technical field [0001] The invention belongs to the technical field of ship equipment, in particular to a ship watertight door. Background technique [0002] At present, warships serve in the harsh marine environment for a long time and will be corroded by salt spray, marine atmosphere and seawater. The effect of an alternating load, especially when attacked, makes the watertight door deformed by force and loses its airtightness. [0003] In recent years, with the continuous development of naval ships, all countries have begun to pay attention to the development of watertight doors, and put forward higher requirements for watertight doors. The existing domestic watertight doors are at a relatively backward level in terms of materials and structural design. They are mainly products designed in Russia in the 1940s and 1950s, which are several generations behind the advanced watertight doors of foreign navies. At present, there are still many problems in the application of wa...

AI Technical Summary

Problems solved by technology

At present, there are still many problems in the application of watertight doors. For example, the parts and grooves of watertight doors are prone to corrosion, and the maintenance workload on the ship is heavy; , resulting in difficulty in opening and closing the watertight door and poor sealing; the shock resistance of the door panel and door frame is poor
