ROV-guided connection device and connection method thereof

Abstract

The invention discloses a ROV-guided connection device and a connection method thereof, relates to the technical field of marine rescue. The bottom of the housing of the connection device is providedwith an integrated connection board. The integrated connection board is provided with a plurality of connectors. The side wall of the housing is equipped with a tension locking mechanism, a bearing seat and a rotary driving device. An umbilical cord passes through the bearing seat to be connected to the connector of the integrated connection board. The housing is also equipped with an ROV storagedevice and an optical cable winch. The ROV storage device is provided therein with an ROV. The ROV is connected to the optical cable winch through a photoelectric composite cable. The bottom of the ROV is provided with a mating hole that matches the center guide post of the integrated connector socket. Channels of a plurality of different media are centrally installed on the integrated connectionboard, and a traditional multiple underwater connection operation is simplified into a single connection operation, thereby improving the efficiency of underwater connection. The umbilical cord is configured to carry out material replenishment and condition monitoring for deep sea equipment to avoid entanglement of various cables under water and reduce the safety risk of underwater connection.

Description

technical field [0001] The invention relates to the technical field of marine rescue, in particular to a plugging device guided by an ROV (Remote Operated Vehicle, remote unmanned submersible) and a plugging method thereof. Background technique [0002] With the promotion of my country's marine strategy, various deep-sea equipment such as HUV (manned submersible vehicle), UUV (unmanned submersible vehicle), deep-sea space station, underwater living cabin, and large-depth diving operation system are being developed or put into use. Due to the limited oxygen, resources, and energy carried by deep-sea equipment, the underwater working time is greatly limited. Before the self-sustaining time expires, it must return to the surface support platform to perform energy supply, data download, and task order re-issue. [0003] Since it takes a long time to deploy and recover deep-sea equipment each time, deep-sea equipment needs to frequently return to the water surface to support the ...

AI Technical Summary

Problems solved by technology

[0004] 1) The transmission of multi-media to deep-sea equipment requires multiple different channels. The integration of existing plug-in devices is not high, and divers or ROVs are required to perform underwater field operations. Multiple underwater plug-in operations are required, which reduces the underwater plug-in efficiency;

[0005] 2) The degree of automation and docking accuracy of existing plugging devices are low, and ROV, ADS (atmospheric pressure diving equipment) and divers' work preparation and underwater operations all take a long time, resulting in the efficiency of underwater plugging Low;

[0006] 3) There are many underwater cables during operation, and various cables are prone to entanglement under the action of ocean currents, which increases the safety risk of underwater plugging
