Problems solved by technology

[0004] To sum up the above, when the distance between the small watertight bead 23 and the door body support 22 reaches a critical value of 1.5m, the existing design method for small hinged watertight doors can no longer meet the requirements for watertight design of watertight doors. The watertight design characteristics of the type watertight door adopts a new watertight design method to meet the watertight design requirements

Abstract

The invention relates to the technical field of watertight doors, in particular to a large hinge type watertight door. The door comprises a door frame and a door body capable of sealing the door frame, a first rocker support is arranged at the center of the end face of the side, opposite to the door frame, of the door body, one end of a rocker is hinged to the first rocker support through a pin shaft, and the other end of the rocker is hinged to the driving end of a driving assembly through a pin shaft, a bending part is arranged on the rocker, a second rocker support is hinged to the position of the bending part through the pin shaft and arranged on the door frame. Reliable sealing of the door body and the door frame of the large hinge type watertight door is achieved in a rocker pushing mode, and effective sealing of the large hinge type watertight door is guaranteed; and a watertight pressing strip and a sealing rubber strip are matched to achieve effective sealing of the door body and the door frame.

Description

technical field [0001] The invention relates to the technical field of watertight doors, in particular to a large hinged watertight door. Background technique [0002] Watertight doors are most commonly used on ships, but of course there are also gates for reservoirs, rivers, ditches, etc. The opening and closing methods of watertight doors can be divided into: hinge type, translation type (sliding type, rolling type) and rolling type, etc. Among them, hinge type watertight door is the most common form of watertight door, which can be applied to various types of doors like household doors. occasion. Its biggest feature is simple and reliable. Generally, the door is small in size and light in weight, and the opening direction is perpendicular to the door frame. This requires that there must be a space to turn and open the door in the direction perpendicular to the door frame. Small hinged doors are generally operated manually. The opening and closing of the door can be comp...
