The invention discloses a device for preventing a hull deck manhole from falling and relates to the field of marine equipment. The device comprises a pipeline and an anti-falling device, wherein an upper surface of the pipeline is rotationally connected with a manhole cover, a steel plate is fixedly installed on a lower surface of the pipeline, and an auxiliary device is arranged on an upper surface of the steel plate; one end of the anti-falling device is provided with an anti-stumbling device, the anti-falling device comprises a clamping block, an inner wall of the clamping block is rotatably connected with a rotating rod, one end of the rotating rod is rotatably connected with a sliding block, a surface of the sliding block is slidably connected with a base, an inner wall of the base is provided with a buffering device, and a surface of the sliding block is provided with a limiting groove. According to the device for preventing the hull deck manhole from falling, by arranging the anti-falling device, when the manhole moves in the direction close to a steel plate under the action of gravity, a clamping block is driven to move in the same direction, meanwhile, a rotating rod rotates in the direction close to a pipeline, and meanwhile, a sliding block slides in the direction away from the pipeline and abuts against a buffering device.
Description
technical field [0001] The invention relates to the field of marine equipment, in particular to a device for preventing a manhole on a deck of a ship from falling. Background technique [0002] The manhole is a safety emergency ventilation device installed on the top of the storage tank. It is usually used in conjunction with a fire extinguisher and a mechanical breathing valve. It has the function of safety fire resistance and is a safety device to protect storage tanks, especially suitable for vaulted atmospheric pressure tanks whose storage materials are capped with nitrogen. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safety and reliability, etc. [0003] At present, most of the existing manholes are too heavy, which is easy to cause them to fall directly, endangering the lives of people inside the manhole, so it needs to be improved.
