An impact pin-type cable severing mechanism consisting of a blade casing, a cable press plate, an ejection control casing, and a movable hook. Provided within the blade casing are a blade and a powerful compression spring below the blade. The ejection control casing is connected with the movable hook. A trigger piece and a blade latch are provided within the ejection control casing. In the impact pin-type cable severing mechanism, when the hook is taut, the blade latch within the ejection control casing is utilized to lock the blade, thus allowing the compression spring to remain in a compressed state, and when the hook is slack, the trigger piece is impacted by a rebound force to drive the blade latch into separating from the blade, and the compression spring is released to eject the blade to the cable press plate to sever a cable. Also disclosed is a use method for employing the cable severing mechanism in a seafloor observatory. The impact pin-type cable severing mechanism of the present invention is capable of effectively severing a cable in equipment when a relevant instruction is received, thus implementing equipment separation. |
