Description

Technical Field

[0001] The invention belongs to the technical field of automatic unhooking devices, in particular to an automatic unhooking device for underwater delivery of a large component. Background Art

[0002] When exploring the ocean, a lift is generally used to lift and lower a tow rope, thereby lifting and lowering large components, thereby placing the large components into the sea.

[0003] After a large component is placed in the sea, there are generally two ways to complete the placement of the large component and allow the towing rope to carry out subsequent work. One is that a worker needs to dive down to take the towing rope, so that the large component can be placed in the sea as a whole and will not affect subsequent work. The other is to use a machine to cut off part of the towing rope so that the large component can be placed. However, the above methods, firstly, are not conducive to manual diving due to the different seabed environments. Secondly, setting up a cutting machine will increase production costs and cause damage to the towing rope, making the towing rope unable to be reused, resulting in increased use costs.
