Abstract

The invention provides a watertight locking device and an installation method thereof. The watertight locking device comprises a connecting rod, a door-penetrating seal kit, a back-surface rotary handle, a front-surface rotary handle, locking pivot levers and door surface pressing block rotary shafts. The locking pivot levers are connected to the upper end and the lower end of the connecting rod;each locking pivot lever is formed by two sections of levers forming an obtuse angle; one door surface pressing block rotary shaft is arranged at an intersection point part of each two sections of levers; the back-surface rotary handle comprises a back-surface rotary handle free end which is handheld during door opening and closing, and a back-surface rotary handle fixed end located at the other end of the back-surface rotary handle; the back-surface rotary handle fixed end is connected with the door-penetrating seal kit; and the front-surface rotary handle comprises a front-surface rotary handle free end, a pivot and a front-surface rotary handle fixed end. According to the locking device, a self-lubricating bearing is adopted on a relative rotation part, so that on one hand, the frictional force is greatly reduced, on the other hand, no lubricating oil needs to be filled, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sealing, and in particular relates to a sealing device on a ship or a submarine and an installation method thereof. Background technique [0002] The watertight door on the ship is arranged in the confined space of the ship or the entrance and exit position of the sealed space. For safety reasons, all watertight doors are normally locked. The locking device generally consists of a block, a lead screw and a handle installed on the door leaf. When opening or closing the waterproof airtight door, manual operation is required. Turn all the locking devices one by one to lock or open the waterproof airtight door. Most of the existing watertight doors of ships are translational. When the door is closed by this mechanism, the left and right sides are limited and locked to ensure that the door frame and door leaf are pressed tightly. Because the door body material is generally made of cast iron, the cast iron ...
