This invention provides a claw-type electrochemical fusing separation mechanism, belonging to the technical field of fusing separation mechanisms. The claw-type electrochemical fusing separation mechanism includes: a separation load housing, a base, a pressure plate, claws, a reversing rod, a fuse, a fuse mounting post, a spring, and
cathode material. This invention utilizes the relative positions of the separation load housing, claws, and reversing rod to achieve locking and separation of the housing. A spring is installed between the pressure plate and the base; the pressure plate compresses the spring, and the fuse load achieves locking of the separation mechanism. The fuse,
cathode material, and
seawater form an electrochemical reaction circuit. The fuse melts due to
seawater corrosion, and the spring, freed from external force constraint, springs open the pressure plate. The movement of the pressure plate is converted into the contraction of the claws via the reversing rod, achieving fusing separation. This invention solves the problems of insufficient locking reliability, low fusing
time control accuracy, and weak adaptability to deep-sea environments in existing claw-type electrochemical fusing separation mechanisms.
