Description

[0001] The invention belongs to the technical field of marine engineering equipment, and in particular relates to a hook-and-loop acoustic releaser with a multiplier. Background Art

[0002] With the gradual deepening of ocean development, the rapid development of deep-sea technology and equipment has been greatly promoted. The number of various bottom-mounted marine equipment and mobile observation equipment has increased sharply.

The acoustic releaser is used to recover underwater equipment deployed by anchors. In the field of marine engineering, the acoustic releaser is a key equipment for the recovery of marine observation systems. However, due to the long working deployment time of underwater equipment and the harsh and complex underwater environment, structural damage and failure of acoustic releasers due to corrosion and erosion by marine organisms often occur.
