Self-repairing underwater cables

Abstract

The invention relates to the field of electric power technologies, and discloses a self-repair underwater cable which comprises an underwater cable body. The underwater cable body is provided with fragile points and repair material bags, the repair material bags are positioned at the fragile points and comprise welding materials and wrapping layers, and the fragile points, the welding materials and the wrapping layers are sequentially arranged at fragile point setting positions in the radial direction of the underwater cable body from the inside to the outside; the welding materials can be melted and connected with the fragile points when the fragile points are broken. The self-repair underwater cable has the advantages that the fragile points are arranged on the traditional underwater cable body, the repair material bags are arranged at the fragile points, resistance of the fragile points is increased after the fragile points are broken, heat can be generated owing to increase of the resistance, accordingly, the welding materials can be melted, and the fragile points can be connected with the welding materials and can be repaired; cooling effects can be realized by water, accordingly, a melting and then shaping mode is applicable to the underwater cable, the self-repair underwater cable can be prevented from being broken, electric power supply or signal communication can be maintained, and the work stability of the traditional underwater cable can be improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an underwater cable. Background technique [0002] After the underwater cable is laid, it will inevitably be pulled and broken due to terrain changes or other external forces. [0003] Traditional underwater cables cannot achieve self-healing, and once broken, they cannot maintain power supply or signal communication. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a self-healing underwater cable to solve the technical problem that the traditional underwater cable cannot realize self-repairing. [0005] The technical problem solved by the present invention can be realized by the following technical solutions: [0006] A self-repairing underwater cable includes an underwater cable body, the underwater cable body is provided with a breakable point, and the self-repairing underwater cable is further provided with a repair material pac...
