Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of salvage anchor for submarine cable, especially relates to a salvage anchor for submarine cable. BACKGROUND
[0002] In deep-sea optical cable maintenance engineering, the salvage link is one of the operations with the most difficulty. Even if modern submarine cable ships and supporting equipment are used, one-time fault repair sometimes still needs one or two months, and most of the time is spent on submarine cable positioning and salvage operations. For submarine cable ships with small tonnage and no dynamic positioning system, the operation time will be longer. When the traditional shear anchor is operating, due to the limitations of its structure and operation mode, it needs to be adjusted in position and angle several times to accurately shear the submarine cable, resulting in long operation time. For example, in an actual maintenance, the use of traditional shear anchor for submarine cable salvage and shearing operation spent nearly a week on positioning and adjustment, and the whole maintenance process took more than a month. Moreover, the operation of the traditional shear anchor is complex, and the operator needs to have high skill level and rich experience, which increases the labor cost and operation risk. In addition, the existing equipment has insufficient adaptability to the diameter of the submarine cable, and when different diameter submarine cables are encountered, different shear anchors often need to be replaced, which not only increases the equipment cost, but also further prolongs the operation time. SUMMARY
