Repair joint of photoelectric composite sea cable

Abstract

The invention discloses a photoelectric composite submarine cable repair joint, which comprises a cylinder and cover boards arranged on two ends of the cylinder, the submarine cable penetrates the cover boards and jointed in the cylinder, the cover board is provided with an airproof fixation piece, a set of electricity conductive drawbars electrically connected with the airproof fixation piece is arranged between the airproof fixation piece and the cylinder, the submarine cable in the cylinder is provided with two mutual assorted inner cylinders, a double components resin is arranged in the two inner cylinder, the outer surface of the cylinder is provided with an optic cable joint package, the optic cable is connected with the optic cable joint package through the cylinder, a double components resin is arranged in the optic cable joint package, the invention has the advantages that: due to the setting of the airproof fixation piece, two fault ends of the submarine cable is fixed, the cutting of the submarine cable in the joint position under an outside force action is avoided; the setting of the electricity conductive drawbars ensures the electric communication between the jacket steel wire of the two submarine cable fault ends; due to the setting of the optic cable joint package, the optic cable is connected with the optic cable joint package through the cylinder and ensures the electric communication of the optic cable; the setting of the double components resin plays the role of anti-corrosion, waterproof, and airproof.

Description

technical field

[0001] The invention relates to a joint, in particular to a repair joint of a photoelectric composite submarine cable. Background technique

[0002] 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 normal operation of the submarine cable, it is necessary to use joints to connect the submarine cable. At present, the connection of submarine cables often uses a soft However, the soft joint can only be connected with special tools at the production site, and the submarine cable connectio...
