Abstract

The invention relates to a watertight hatch cover, in particular to a quick open and close pressure proof watertight hatch cover and belongs to the technical field of ship outfitting. The quick open and close pressure proof watertight hatch cover comprises a coaming plate, a lower base plate, a lock catch device, an upper base plate, a watertight rubber strip, a cover plate, a hand wheel transmission mechanism, linkage compression devices, inclined wedges and a spring hinge device; the upper end of the lower base plate supports the upper base plate; the coaming plate is welded to the lower end of the lower base plate; the cover plate is welded to the upper end of the upper base plate; one sides of the lower base plate and the upper base plate are provided with the spring hinge device; the other sides of the lower base plate and the upper base plate are provided with the lock catch device; the hand wheel transmission mechanism is welded to the center of the cover plate. According to the quick open and close pressure proof watertight hatch cover, the hatch is quickly opened or closed through the central hand wheel transmission mechanism and the spring hinge device, the opening and closing are rapid and convenient, fixation of an insertion pin with a tongue is safe and reliable, the watertight experimental pressure achieves 0.5MPa, water is effectively obstructed from expanding to an engine room and other cabins at inlets and outlets, and accordingly normal operation of machines in the cabin is guaranteed and the safe escape of the personnel is guaranteed and the property loss is reduced.

Description

technical field [0001] The invention relates to a watertight hatch cover, in particular to a quick opening and closing pressure-resistant watertight hatch cover, which belongs to the technical field of ship outfitting. Background technique [0002] With the development of the ship industry, customers have higher and higher requirements for ship outfitting equipment. In the existing technology, the watertight hatch cover is mainly composed of a base, a clip device, a cover plate, a hinge device, a bevel, a handle, a lock, etc. Buckle device and other connection components. This kind of watertight hatch cover is opened or closed by multiple clip devices on the cover plate, and then opened and closed by hinge devices on the cover and frame. The maximum watertight test pressure of this kind of watertight hatch cover is 0.05MPa. Therefore, this hatch cover is loaded down with trivial details and slow to open, and watertight pressure is low, can not satisfy the needs of customer...
