Abstract

The invention relates to a hydraulic watertight hatch cover device capable of opening and closing automatically. The hydraulic watertight hatch cover device comprises a hatch cover (2) and a door opening (13) which is formed in a deck (1), an opening/closing hydraulic cylinder (3), a locking hydraulic cylinder (4) and a wedging mechanism, wherein the hatch cover (2) is hinged to the inner side of the deck (1); the two ends of the opening/closing hydraulic cylinder (3) are respectively hinged to the inner side of the deck (1) and the hatch cover (2); the locking hydraulic cylinder (4) is arranged on the inner side of the deck (1); a sealing ring (14) is arranged on the peripheral wall of the hatch cover (2); and when the hatch cover (2) rotates to be in a closing state, the locking hydraulic cylinder (4) drives the wedging mechanism to act, and the wedging mechanism is supported at the bottom of the hatch cover (2) to press the sealing ring at the lower end of the door opening (13). Compared with the prior art, the hatch cover device has a high degree of automation, is convenient to operate and high in bearing capacity, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of ships, in particular to a hydraulic watertight hatch cover device capable of automatic opening and closing. Background technique [0002] For a long time, ship hatch covers have been used as closing devices for deck openings, and the structure and form mostly adopt the traditional method, that is, the cover plate is installed on the deck through hinges, and is locked and pressed tightly with a latch. When opening the cover plate, it is turned over by manpower, and it is placed flat on the deck. The cover plate is all positioned on the deck when it is opened and closed, which takes up space and affects the appearance. Moreover, at the sealing position, the deck surface has relatively large protrusions or depressions, and the load that the cover plate can bear is limited. The opening and closing of the deck, the locking of the pin shaft, and the sealing of the cover plate all need manual operation, and the degree of...
