Abstract

A locking device of an umbilical connector comprises a socket and a plug. When the plug is plugged into the socket, a locking ball inside the socket falls into a groove in the plug and is limited by a locking hoop. The socket is in fixed connection with a socket panel. The locking hoop on the socket is in fixed connection with a movable plate. The plug is in fixed connection with a plug panel. The plug panel is rotatably connected with a rotating shaft. A part is arranged on the rotating shaft to push the movable plate to move. A fixing shaft is arranged on the plug panel and is provided with a notch which can be locked by a flange on the rotating shaft. The locking device is compact in structure, easy and convenient in operation, and high in reliability. The locking device has a self-locking function after a butt joint. Through operation of a diver or an underwater robot, a plurality of loops can be simultaneously engaged or disengaged, and thus the work efficiency is high. The locking device is used for rapid connection of umbilicals in a deep ocean, and can disengage umbilicals rapidly in an emergency. The locking device can also be used for rapid connection of an umbilical with an underwater Christmas tree SCM in a deep ocean.

Description

The locking device of umbilical cables connector

Technical field

The utility model relates to the umbilical cables of control system under water and the interconnection technique between the umbilical cables, particularly a kind of locking device of umbilical cables connector in the ocean deepwater petroleum drilling and mining field.

Background technology

In the prior art, the control system under water in ocean deepwater petroleum drilling and mining field often needs to interconnect between umbilical cables and the umbilical cables.Generally, umbilical cables is docked the normal weight of butt plate self that relies on and is guaranteed can not break away from automatically after the butt joint, but does not dock the back auto-lock function, so its reliability is not high.When operational environment is abominable, be subjected to external force such as extraneous vibration environmental impact, ocean current impact under water to do the time spent as system, the banjo fixing butt jointing in the butt plate can produce loosening phenomenon, easily causes the loop situations such as micro-leakage to occur, reduces the sealing property of system.Simultaneously, because the weight of butt plate self is bigger, butt joint or disengaging operation be difficulty, and operation process is had relatively high expectations to operating personnel or operating equipment, and butt joint and second cosmic velocity are very slow.
