The invention discloses a locking piece type underwater rapid locking device. The locking piece type underwater rapid locking device comprises a connecting cover plate and a locking piece control mechanism. According to the structure of the locking piece control mechanism, a remotely operated vehicle (ROV) handle is arranged in an operating mounting hole of an ROV panel; a fixed sleeve is disposed inside the connecting cover plate, and locking pieces are correspondingly arranged in multiple lock holes in the outer wall of the fixed sleeve; the outer wall of the fixed sleeve is sleeved with a floating sleeve, and handle lock holes are formed in the wall of the floating sleeve; a bush is arranged on the surface of an inner cavity of the fixed sleeve, and a round through hole is formed both in the wall of the fixed sleeve and the wall of the bush; an inner cavity of the bush is provided with a locking shaft, and a semi-cylindrical lock groove is formed in the upper portion of the outer wall of the locking shaft; at least one round-angle trapezoidal groove is formed in the lower portion of the outer wall of the locking shaft, and the position of each round-angle trapezoidal groove corresponds to that of the corresponding locking piece; a guiding shaft is disposed at the upper end of the locking shaft, and a spring is arranged between the outer wall of the guiding shaft and a blind hole of the axis of the locking shaft in a sleeving mode. The locking piece type underwater rapid locking device is simple in structure and can work reliably.
Description
technical field [0001] The invention belongs to the technical field of offshore oil and gas production equipment, and relates to a locking block type underwater quick locking device. Background technique [0002] At present, the underwater throttle valve, underwater chemical injection valve, underwater control module and other unit equipment in the marine underwater oil and gas production system require regular recovery and maintenance and reinstallation during use, and the existing technology cannot meet the requirements. The fast locking and unlocking operation requirements for offshore oil and gas production equipment under deep water conditions require a fast locking and unlocking device for underwater hoisting. Fast locking and unlocking operations. Contents of the invention [0003] The purpose of the present invention is to provide a locking block type underwater quick locking device, which solves the problem that the lowering and recovery tools in the prior art ca...
