A rotary underwater wet-plug photoelectric composite connector

Abstract

The invention discloses a rotary type underwater wet plugging photoelectric composite connector, which comprises a socket and a plug cooperated with the socket, wherein a plug body is a plug inner cavity, and a plug photoelectric insertion core penetrates through the inner part of the plug body; a socket body is a socket middle sleeve and forms a socket inner cavity with a socket end surface and asocket rubber clapboard, and a socket photoelectric insertion core penetrates through the inner part of the socket body; the plug and the socket are cooperated with a spiral groove on the surface ofa central shaft in the plug through a bulge in the round pipe of the end surface of the socket; and linear motion between the plug and the socket is converted into the common rotary motion of two endsurfaces, and a channel for insertion between insertion needles is left for realizing connection. The connector is provided with a rubber bag with variable volume as a pressure balance device, and waterproof sealing performance is fully considered. The connector integrates optical signals with power transmission, so that a structure is simple, an insertion process is simple, and the reliable connection of a deep water environment can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a rotary underwater wet-plug photoelectric composite connector, which is suitable for underwater environments, especially deep-sea environments. Background technique [0002] With the continuous deepening of people's exploration in the marine environment, offshore oil and gas development, marine exploration, underwater offensive and defensive combat systems, etc. continue to develop in the deep sea field. These marine engineering fields require a large number of underwater operations, and different working modules need to transmit power and optical signals through connectors. Most of the existing underwater connectors are dry-swappable connectors without a pressure balance structure. It is difficult to achieve a good seal in a deep-water environment. The equipment needs to be taken out above the water surface for plug-in operations, maintenance, and updates...

AI Technical Summary

Problems solved by technology

Most of the existing underwater connectors are dry-swappable connectors without a pressure balance structure. It is difficult to achieve a good seal in a deep-water environment. The equipment needs to be taken out above the water surface during plugging operations, maintenance, and updates. The operation is complicated and the cost is too high. Therefore, there is an urgent need for a connector that can adapt to underwater high-pressure, high-corrosion environments, and can realize multiple plugging and unplugging operations underwater
