AI Technical Summary

Technical Problem

Existing deep-sea release devices are prone to deformation and seal failure in deep-sea environments. The motor drive has difficulty driving the hook components, key moving parts are prone to corrosion and adhesion, and the transducer is easily damaged, resulting in the inability of the equipment to be recovered normally.

Method used

An acoustic release device was designed, which uses a tension rod to connect the transducer module and the release module to reduce the tensile load on the cabin. The tension rod and mounting ring are set inside the cabin to enhance the sealing performance and protect the transducer module. A motor assembly is used to drive the locking component to realize the automatic unlocking of the hook component and protect the transducer with the cage.

Benefits of technology

It effectively prevents cabin deformation, maintains airtightness, reduces motor drive force requirements, protects key components, and improves the reliability and lifespan of equipment in deep-sea environments.

Abstract

This utility model relates to the field of deep-sea operation equipment deployment and recovery, and provides an acoustic release device, including a transducer module, a housing, and a release module. The housing is a hollow cylindrical shape, with the transducer module located at the top of the housing and the release module located at the bottom. A tension rod is provided inside the housing, with its two ends fixedly connected to the transducer module and the release module, respectively. The rod body is spaced apart from the inner wall of the housing. The acoustic release device provided by this utility model has a housing that is not easily deformed under tension, which helps to maintain a tight seal inside the housing.
