Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable monitoring, in particular to a mobile submarine cable status monitoring device which can be quickly fixed. Background Art

[0002] Nearshore submarine cables are usually buried in the seabed through laying equipment, while in the open sea there are some submarine cables suspended in the seawater. The complex seabed environment can easily cause varying degrees of damage to submarine cables. In order to ensure the normal operation of submarine cables, detect problems in a timely manner and perform timely maintenance, it is necessary to monitor the status of submarine cables in a timely manner.

[0003] For example, the submarine cable disturbance monitoring device of Chinese patent CN220893249U monitors the disturbance of the submarine cable through a displacement sensor sealed in a casing, and limits the bending degree of the submarine cable through the casing and casing limit clamp to avoid excessive bending and damage of the submarine cable at the cable connection.

[0004] However, the surface of the submarine cable is worn to varying degrees due to the impact and biting of fish or the long-term erosion and friction of ocean currents. It is difficult to achieve comprehensive monitoring over long distances. At the same time, the submarine cable is driven to vibrate in the water by seabed currents or eddies, and overload vibration can cause fatigue damage to the submarine cable.

[0005] Based on this, the utility model designs a mobile submarine cable status monitoring device that can be quickly fixed to solve the above problems. Utility Model Content
