Underwater mini-type conductive pulling ring

Abstract

The invention relates to an underwater mini-type conductive pulling ring. A stator fixing body and a conductive stator are connected with the upper end of a shell body. The conductive stator is fixed to the middle of the stator fixing body through a fixing nut. A wire of the stator is connected with a watertight connector and fixed to the upper end of the stator fixing body. An upper pulling ring body and a connecting piece are fixed to the upper end of the stator fixing body through threads. An upper centripetal thrust bearing and a lower centripetal thrust bearing are arranged in the middle of the shell body. The upper centripetal thrust bearing and the lower centripetal thrust bearing are matched with a rotary shaft through adjusting nuts and lock washers. A conductive rotor is connected and fixed to the lower end of the rotary shaft through a multi-core cable and a watertight connector. A lower pulling ring body and a lower connecting piece are fixed to the lower end of the rotary shaft through threads. A pressure balancing sealing device is arranged on the lower portion of the shell body. An oiling port and an air exhaust port are formed in the shell body. The upper portion of the shell body is sealed through an O-shaped ring. The underwater mini-type conductive pulling ring enables field installation and construction to be convenient and has the low requirements for submarine cables.

Description

technical field [0001] The invention belongs to the field of marine technology, and relates to an underwater miniature conductive pull ring, which is a conductive pull ring for an underwater cable, and a plurality of pull rings can be connected in series on one submarine cable. Background technique [0002] Today's ocean observation and monitoring are gradually becoming real-time, networked, and informatized. In the past, the self-contained submersible mark storage sensor was used to collect data and then the ship went to the designated place to recover the submerged mark to obtain information, which could no longer meet the growing national marine undertakings. The premise of real-time and informatization is the reliable and stable transmission of a large amount of data in real time. This transmission method is easy to realize on land, but it becomes extremely difficult in the sea, especially underwater. The deeper the water depth, the greater the water pressure, and every...

AI Technical Summary

Problems solved by technology

Adopting the present invention can effectively solve the problem that the tension and torsion of the submarine cable cannot be released by itself caused by the ocean current and tide and the movement of underwater equipment. Under the premise of ensuring data communication, the torsion received by the cable can make the pull ring rotate freely and release the tension in the cable. torque, which in turn can ensure long-term stable and reliable transmission of data
