Underwater balance type barrel cover opening system and using method thereof

Abstract

The invention provides an underwater balance type barrel cover opening system and a using method thereof. The problems of gravity and buoyancy balance, buoyancy loss and the like of a barrel cover before and after cover opening can be effectively solved. In the barrel cover opening system, a barrel cover assembly in a zero-buoyancy state covers a top opening of a barrel body opening part and is used for sealing the top opening of the barrel body opening part; a pressure equalizing subsystem is used for realizing pressure equalizing inside and outside the barrel body opening part before the barrel cover assembly is opened; an auxiliary cover jacking subsystem and a cover jacking and screwing subsystem are fixed to the two opposite sides of the outer circumference of the barrel body opening part correspondingly; the cover jacking and screwing subsystem comprises a hydraulic cover jacking assembly and a hydraulic cover screwing assembly; the hydraulic cover jacking assembly and the auxiliary cover jacking system respectively eject or pull down the barrel cover assembly from two sides through a hydraulic oil cylinder; the hydraulic cover screwing assembly is used for driving the barrel cover assembly to horizontally rotate for opening or closing; a detection subsystem is used for detecting in-place of cover jacking, in-place of cover closing and a rotation angle; and a hydraulic subsystem controls the auxiliary cover jacking system and the cover jacking and screwing system to act according to an instruction of a barrel cover controller.

Description

technical field [0001] The invention relates to a cylinder cover opening system and its use method, in particular to an underwater balanced cylinder cover opening system and its use method, belonging to the technical field of underwater equipment. Background technique [0002] The canopy cover opening device is an important part of the underwater platform, which is mainly used to realize the opening and closing functions of the canopy cover before and after the payload inside the underwater platform enters the external seawater. For underwater platforms, openings are often the weak link for pressure and sealing. In order to ensure the pressure resistance performance, it is required that the cylinder cover must ensure sufficient structural strength, resulting in the weight of the cylinder cover is often relatively large. During the opening process of the canister cover, the center of gravity and the center of buoyancy of the canister cover are constantly changing, which will...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the existing lid opening mechanism in the prior art and provide an underwater balanced lid opening system, which can effectively solve the problems of gravity and buoyancy balance and buoyancy loss of the lid before and after opening the lid. Not only suitable for large underwater platforms that need to be opened, but especially suitable for small underwater platforms that require high stability and balance
