Description

technical field [0001] The invention belongs to the technical field of marine instruments and equipment, and in particular relates to an underwater magnetic release and docking device. Background technique [0002] In the field of marine research, various sensing devices are usually deployed underwater. These sensing devices are installed on various mooring structures, connected with the mooring weights through release devices, and anchored to the seabed. When the mooring structure equipped with sensing equipment needs to be recovered, the release device at the bottom of the mooring structure is decoupled from the mooring weight, and the mooring structure can float out of the sea under the action of positive buoyancy. [0003] At present, the commonly used release device is an acoustic response release device, which is divided into a control part on the water surface, a response part under the water surface and a release part. The control part on the surface of the water se...

AI Technical Summary

Problems solved by technology

The acoustic response release device can only realize the function of releasing and unhooking. Once the mechanical release hook is disengaged, it can only be reset manually on the shore, and cannot be reconnected underwater.
