The invention discloses a device for preventing falling of a manhole on a hull deck. The invention relates to the field of marine equipment, including a pipeline and a fall prevention device. The upper surface of the pipeline is rotatably connected to a manhole cover, and the lower surface of the pipeline is fixedly installed with a steel plate. The upper surface of the steel plate is provided with an auxiliary device, one end of the anti-fall device is provided with an anti-stumbling device, the anti-fall device includes a clamping block, the inner wall of the clamping block is rotatably connected with a rotating rod, and one end of the rotating rod is rotatably connected with a slider, The surface of the slider is slidably connected with a base, the inner wall of the base is provided with a buffer device, and the surface of the slider is provided with a limiting groove. The device used to prevent the falling of the manhole on the hull deck is provided with the anti-falling device. When the manhole is displaced towards the steel plate by gravity, the clamping block is driven to move in the same direction, and at the same time the rotating rod rotates towards the direction of the pipeline. Simultaneously, the slide block slides in a direction away from the pipeline, and is opposed to the buffer 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.
