Abstract

PURPOSE: To safely perform the self-sinking operation of a buoy by energizing the stopper provided to a buoy with an electric signal.
CONSTITUTION: A hole 13 is provided in a wall surface 11 of a buoy 1, allowing the inside and the outside to communicate with each other. Said hole 13 has a recess 14 of large diameter, into which an O-ring 15 is fitted, and a stopper 16 is inserted and fitted in the hole 13. The stopper 16 has an actuating shaft 22 combined with an actuating piece 21 to be attracted by an electromagnet 20. When the instruction signal from a remote place is received, a relay 31 is energized. Consequently, a contact 32 is closed to actuate the electromagnet 20 to attract the actuating piece 21 in the direction of an arrow A, causing the stopper 16 to be pushed outward. Thereby, the hole 13 is opened, so that seawater flows into the buoy 1. Consequently, the buoy 1 loses buoyancy and sinks under the water.
