Description

Technical Field

[0001] This invention relates to the technical field of deep-sea exploration, and more specifically, to a non-powered cable release device. Background Technology

[0002] When conducting deep-sea exploration or underwater platform depth determination operations, it is necessary to deploy moorings in deep-sea areas. When deploying, the order is usually mooring first and then anchoring. The cables, moorings, and anchor blocks used for depth determination at several thousand meters are scattered on the aft deck of the ship before deployment.

[0003] However, in actual operation, due to the excessive length of the cable, knots are very likely to occur during the deployment of the buoy and anchor blocks, especially in rough sea conditions, posing a great safety hazard to the operation. Summary of the Invention
