Folding type watertight door

Abstract

The invention relates to a folding type watertight door which comprises a door frame and a door leaf, wherein the door leaf comprises a left door leaf and a right door leaf, and the adjacent vertical edges of the left door leaf and the right door leaf are together articulated; the inner side surface of the right vertical frame of the door frame is provided with a first pin seat, a second pin seat and a third pin seat; a chain plate is positioned between the outer vertical edge of the right door leaf and the first pin seat; the inner side surface of the adjacent edge of the right door leaf is provided with a fourth pin seat and a fifth pin seat; a hydraulic cylinder is connected between the fourth pin seat and the second pin seat; a second connecting rod and a first connecting rod are positioned between the fifth pin seat and the third pin seat; one ends of the second connecting rod and the first connecting rod are respectively articulated with the fifth pin seat and the third pin seat, and the other ends of the second connecting rod and the first connecting rod are respectively together articulated; the inner side surface of the adjacent edge of the left door leaf is provided with a sixth pin seat; the connecting end of the second connecting rod and the third connecting rod is together articulated with one end of the third connecting rod; the other end of the third connecting rod is together articulated with the sixth pin seat; and in the door closing state, the adjacent edges of the left door leaf and the right door leaf are matched in a sealing way, and the door leaf and the right door leaf are matched with the door frame in a sealing way. With the adoption of the folding type watertight door, the utilization rate of a cabin can be improved, and the folding type watertight door is suitable for various ships.

Description

technical field [0001] The invention relates to a cabin door for a ship. Specifically, it is a folding cabin door with watertight performance that is used for navigators to board or disembark, and is applicable to various ships. Background technique [0002] It is well known in the shipbuilding industry that when a ship docks at the dock, a port navigator needs to board the ship with the help of a ladder to guide the ship's channel, and the length of the software in it should not exceed 9 meters according to the specifications. For ships with a low main deck, the soft ladder can be lowered directly from the main deck to the water surface. However, for ships with a higher main deck, the ladder must be lowered to the water surface through the watertight door on the side of the ship. And when the navigator boards the ship or when the pilot is not needed, the watertight door on the side of the ship needs to be closed again. At present, most of the watertight doors used to rel...

Problems solved by technology

At present, most of the watertight doors used to release the soft ladder for the navigator to get on and off the ship are translation watertight doors. When this kind of translation watertight door is opened, it needs to occupy the valuable space in the cabin, which makes the utilization rate of the cabin low, which is not conducive to other ships on board. equipment layout
