Photoelectric composite sea cable repairing joint

Abstract

The present invention discloses a mending joint of photoelectric complex of submarine cable, which comprises a barrel and cover plates arranged on two ends of barrel. The submarine cable passes through the cover plates and is jointed in the barrel. Each cover plate is provided with a sealing fixing piece. A group of conductive tension rods which is electrically connected with the sealing fixing piece is installed between the sealing fixing piece and the barrel. The submarine cable in the barrel is provided with two inner barrels which cooperate with each other. A two-component resin is provided in the two inner barrels. The external surface of barrel is provided with an optical cable joint package. The optical cable is connected with the optical cable joint package through the barrel. The two-component resin is provided in the optical cable joint package. The mending joint according to the invention has the advantage that two ends of submarine cable are fixed as the sealing fixing piece is installed. The disconnection of joint of submarine cable under external force function is prevented. The electric connection between the armoured steel wires at two ends of submarine cable is ensured through the installation of conductive tension rod. As an optical cable joint package is provided, the optical fiber is connected with the joint package through the barrel and guarantees the electric connection of optical cable. The installation of double-component resin has the functions of corrosion prevention and waterproof sealing.

Description

[0001] This application is a divisional application of the original application number 200710156467.5 for a patent application for invention, the filing date of which is October 31, 2007, and the title of the invention is "a repair joint for a photoelectric composite submarine cable". technical field [0002] The invention relates to a joint, in particular to a repair joint of a photoelectric composite submarine cable. Background technique [0003] With the rapid development of economy and construction, many offshore islands and marine facilities such as offshore oil and natural gas work platforms have demands for various resources such as electricity, communications, fresh water, oil, and gas, and various seabeds have to be deployed separately. A large number of pipelines such as optical cables and submarine power cables. Submarine optical cables or submarine power cables often fail due to various reasons during the long-term use of the submarine. In order to ensure the nor...

AI Technical Summary

Problems solved by technology

Submarine optical cables or submarine power cables often fail due to various reasons during the long-term use of the submarine. In order to ensure the normal operation of the submarine cable, it is necessary to use joints to connect the submarine cable at the fault point. At present, the connection of the submarine cable often uses a soft But the soft joint can only be spliced ​​with special tools at the production site, and it cannot be spliced ​​at sea
