Seabed shearing salvaging device for undersea cable

Abstract

The invention discloses a seabed shearing salvaging device for an undersea cable and belongs to the fields such as mechanical control, hydraulic control, automatic control, and the like. The seabed shearing salvaging device comprises a shearing mechanism, a holding mechanism, an electronic cabin, a hydraulic system and two capturing cable plates which are mounted on a device frame, wherein a tip anchor palm is used for introducing a fault undersea cable into the shearing mechanism and the holding mechanism; the undersea cable is sheared by the shearing mechanism; two broken ends of the undersea cable are tightly held by the holding mechanism; the holding mechanism is connected to cables in the capturing cable plates, thereby being capable of salvaging the two broken ends of the undersea cable out of the water and maintaining by releasing the holding mechanism; and the electronic cabin is connected to the hydraulic system and is used for sending a control instruction to the hydraulic system, thereby controlling the holding mechanism and the shearing mechanism to operate by the hydraulic system. The seabed shearing salvaging device for the undersea cable has the advantages that the seabed shearing salvaging device is suitable for operations under deep water; the seabed shearing salvaging device can automatically shear the undersea cable, hold the broken ends and connect the lifted cable at 2 kilometers deep-sea bottom; the manufacturing cost is low and the operation is simple; and the problem of repeatedly salvaging the broken ends during a process of salvaging the undersea cable is solved.

Description

technical field [0001] The invention relates to the fields of machinery, hydraulic pressure, automatic control and the like, and specifically relates to a deep-sea optical cable submarine shearing and fishing device. Background technique [0002] In deep-sea optical cable maintenance operations, in order to solve the problem that the submarine cable cannot be directly lifted to the water surface, it is necessary to use a shearing and salvage device to cut the submarine cable first and then salvage it. The "deep-sea optical cable submarine shearing and fishing device" is a special equipment for deep-sea optical cable cutting and salvage, which is suitable for all submarine cables, optical cables and steel cables with a diameter of 19-45mm. [0003] In the entire deep-sea optical cable maintenance project, the most difficult operation should be the salvage of the submarine cable. Even with modern submarine cable ships and supporting equipment, sometimes it takes one or two mo...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing deep-sea optical cable salvage and shearing equipment is only a single underwater shearing, or grasping a broken end after cutting, there is a problem of finding the broken end again and salvaging again, and the difficulty and workload of follow-up operations are still very large
