Background After sinking the detector into the set water depth, releasing the detector to acquire profile data in the floating process, which is a key step for acquiring high-quality hydrologic data in marine scientific investigation. Currently, achieving this function relies mainly on two dominant techniques, electromagnetic release and acoustic release. The electromagnetic release technology mainly utilizes the strong attraction of the permanent magnet to firmly adsorb the locking piece at a fixed position, so that the whole mechanical structure is locked, when the electromagnetic release technology is in release action, current is introduced into the electromagnetic coil to generate a magnetic field opposite to the magnetic field of the permanent magnet, the original magnetic force is counteracted, the locking piece is reset under the action of a spring or other mechanisms, and the mechanical structure which is originally locked is immediately unlocked. The acoustic release technology generally adopts a mechanical structure to restrain a load, for example, a hook and loop system, a rotating pin, a connecting rod and other mechanical mechanisms are used for locking the load, in addition, in order to reduce the load borne by a motor, a multiplier is usually required to be arranged or a lever ratio design is carried out, when the load is released, a release instruction is received through an underwater acoustic transducer, an internal motor is activated, the motor rotates to drive key parts to displace, the interlocking state of the original mechanical structure is damaged, and a hook is disconnected.
