[0002] Linear towed deep-sea hydrophones are important equipment in marine geophysical surveys, capable of receiving acoustic reflection signals from the seabed. However, existing deep-sea hydrophones lack automatic retraction and winding functions, which can cause long cables to become tangled and coiled during winding, affecting their performance.

The mounting frame and base are fixedly connected. The storage component is mounted on the mounting frame, and the transmission component is mounted on the base. The transmission component is configured to work with the hydrophone component, which is mounted on the storage component. This easy-to-retract deep-sea hydrophone, through its integrated design, enables automatic cable retraction and deployment, reducing manual labor and improving cable winding efficiency, preventing cable tangling. Furthermore, the design removes seawater from the cable during winding, preventing residual seawater from corroding the cable and the retraction / deployment device, thus improving performance.

This could easily corrode the components and affect their lifespan. Therefore, an easy-to-retract deep-sea microphone was designed to solve this problem. Utility Model Content
