Spring type automatic locking device for underwater control module

Abstract

The invention provides a spring type automatic locking device for an underwater control module. The spring type automatic locking device mainly comprises a ring, a guide sleeve, a center shaft, a support column, an inner locking sleeve, a fixed cover, a lock core, a sliding block, a locking spring, a return spring an outer locking sleeve and a guide head and is used for butt joint, locking and unlocking of an upper connection disc and a lower connection disc of the underwater control module. After butt joint, the ring is released, automatic locking is achieved under the action of the locking spring and the return spring, and thus breakover of the underwater control module with electric and liquid functional elements and the like of underwater production equipment in an inserting-connecting mode is achieved, and the positions of all the functional elements are kept fixed. When the underwater control module needs maintenance and replacement, automatic unlocking can be achieved by pulling the ring directly through a manipulator on an ROV. The difficult technical problems of too long consumed time and difficult locking of the operation process when locking and unlocking are conducted by a torque tool through the ROV. The spring type automatic locking device is compact in inner structure and suitable for operation in a deepwater environment, and the butt joint, locking and unlocking efficiency is improved significantly.

Description

technical field [0001] The invention relates to an automatic locking device, in particular to a spring-type automatic locking device for an underwater control module, which belongs to the technical field of marine engineering. Background technique [0002] The underwater control module is the key equipment of deep sea oil production, and the study of the underwater control module is of great significance to the development of deep sea oil production in my country and the guarantee of oil safety in my country. The main function of the underwater control module is to control the various valves of the underwater production system, monitor the status of the underwater production system, and timely feed back the information of the submarine equipment to the equipment on the sea surface, and at the same time coordinate the functions of the various parts of the surface production platform and the underwater production system . The locking device of the subsea control module is an ...

AI Technical Summary

Problems solved by technology

When the underwater control module needs to be repaired or replaced, it can be automatically unlocked by directly pulling the hoisting mechanism through the manipulator on the ROV, which effectively solves the traditional method of using torque tools to lock and unlock through the ROV. The operation process takes too long , a difficult technical problem in locking
