Description

Technical Field

[0001] The utility model belongs to the technical field of submarine cable detection, and specifically refers to a submarine cable fault detection and positioning device. Background Art

[0002] Submarine cables, also known as submarine optical cables, are optical fiber cables laid on the seabed, primarily used to connect international waters and enable cross-border communications. With the rapid development of global communications networks, submarine cables, as crucial infrastructure for international communications, are receiving increasing attention for their safety and stability. However, due to the complex and ever-changing submarine environment, submarine cables are prone to failures such as breakage, short circuits, and bending over long periods of use. If these failures are not promptly detected, located, and repaired, they can severely impact international communications.

[0003] At present, although the submarine cable fault detection and positioning equipment on the market can meet the detection needs to a certain extent, it still has many shortcomings. For example, the existing detection equipment lacks stability when clamping the submarine cable, which can easily cause damage to the submarine cable during the detection process. The detection method is single, and it is difficult to comprehensively and accurately determine the type and location of the submarine cable fault. The mobility is limited in complex seabed terrain, making it difficult to cover all detection areas. Utility Model Content
