Abstract
PURPOSE: To reduce vibration and shaking motion or the like of a spar buoy placed in a violent tidal current, by providing in the spar buoy a resistant body equipped with water current and vibration resistant plates.
CONSTITUTION: A buoyant body 3 is provided on part of a sign pole 2 equipped with a lamp unit 1 at its top, then its bottom end is linked to a sinker 5 on the sea bottom by a mooring cable 4, thus the sign pole 2 is moored. A resistant body 6 is equipped at a position below the buoyant body 3 and constituted by a water current resistant plate 7 in the direction at a right angle with a water current and a vibration resistant plate 8 in the direction of the water current, here with a larger area of the water current resistant plate 7 than the vibration resistant plate 8. In short, the water current resistant plate 7 is formed in length l1 larger than length l2 of the vibration resistant plate 8, in this way, the resistant body 6 can hold a stable position in the stream of water to also reduce vibration and shaking motion or the like of a spar buoy due to a tidal current.
