Hydraulic sliding type watertight door for ship

Abstract

The invention relates to a hydraulic sliding type watertight door for a ship, comprising a door frame and a door leaf, wherein the door frame comprises a main door frame around which an auxiliary door frame is arranged; the door leaf is positioned on the inner side of the main door frame and comprises an edge frame in which a door plate is arranged. A sealing strip is arranged between the main door frame and the edge frame; the upper part and the bottom of the main door frame are provided with guide rails adapting to the length of the lower edge of the main door frame, the guide rails are fixedly connected with the main door frame, and the upper part and the bottom of the door leaf are provided with rollers which are movably matched with the guide rails; and the upper part of the guide rail at the upper part and the lower part of the guide rail at the lower part are provided with hydraulic oil cylinders, one ends of the hydraulic oil cylinders are articulated with one end of the guide rails, and the other ends are articulated with the upper and lower edges of the door leaf. The hydraulic sliding type watertight door is characterized in that fireproofing plates are arranged on the exposed face of the main door frame and the inner and outer faces of the door plate, and fireproofing strips are arranged between the periphery of the door plate and the main door frame. The watertight door has the advantages of watertight performance, fireproofing performance and no limitation on the using range and is suitable for the ship and bulkhead openings of and various ocean engineering equipment.

Description

technical field [0001] The invention relates to a watertight door. Specifically, it is a watertight door with fire protection function. Suitable for bulkhead openings of ships and various marine engineering equipment. Background technique [0002] It is well known in the shipbuilding and various ocean engineering equipment manufacturing industries that in order to solve the watertight problems of ships and various ocean engineering equipment, watertight doors need to be installed on the bulkhead openings of ships and various ocean engineering equipment. A traditional watertight door includes a door frame and a door leaf. The door frame includes a main door frame, and there are auxiliary door frames around the main door frame. The main door frame and the auxiliary door frames are connected together in a sealed shape. There is a door leaf on the inner side of the main door frame, the door leaf contains a frame, and there is a door panel inside the frame, and the periphery of...

AI Technical Summary

Problems solved by technology

This kind of watertight door has only watertight performance, no fireproof performance, and few functions. It is difficult to meet the needs of both watertight and fireproof ships and marine engineering equipment, and the scope of use is limited.
