【作用】請求項１記載の本発明によれば、波の静かな時
は重錘を消波板の回動の支点位置におき、消波板を海中
で水平に位置させる。よって、この状態ではその上を船
舶が自由に航行できる。According to the present invention, when the wave is quiet, the weight is placed at the fulcrum position of the rotation of the wave-eliminating plate, and the wave-eliminating plate is positioned horizontally in the sea. Therefore, in this state, the ship can freely sail on it.
【０００７】波浪のある場合は、重錘を回動の支点位置
からずらせば、消波板が傾斜しその一端が海上に出現す

組んだものである。Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a front view showing a first embodiment of a wave breaking device of the present invention, in which a foundation 1 consisting of a rubble mound 2 and a concrete foundation 3 is provided on the seabed, and a pedestal 4 is installed on the foundation 1. The pedestal 4 is formed by assembling the inclined legs 6 on the support legs 5 in a mountain shape.

めのストッパーである。Reference numeral 7 in the drawing denotes a wave-dissipating plate installed on the inclined leg 5, and the center of the wave-dissipating plate 7 is a mountain-shaped apex 6a of the inclined leg 6.
A pin 10 is attached to the shaft so that it can rotate in the vertical direction. Thus, the weight 8 is slidably provided on the upper surface of the wave-dissipating plate 7 rotatably attached to the inclined leg 6 like a seesaw with the apex 6a as a fulcrum. Reference numeral 9 is a stopper for preventing the weight 8 from falling when tilting.

が海中にあり、海面は消波板７の上方に位置し、消波板
７の上方を船舶が自由に航行できる。The operation will now be described. When the wave is quiet, the weight 8 is positioned at the apex 6a at the center of the wave-eliminating plate 7, that is, at the fulcrum of rotation, and the wave-eliminating plate 7 is inclined. It is balanced at the apex 6a and held in a horizontal state (chain line position in FIG. 1). Therefore, the wave-dissipating plate 7 is entirely in the sea in this horizontal state, the sea surface is located above the wave-dissipating plate 7, and the ship can freely navigate above the wave-dissipating plate 7.

の側が上昇して傾斜する（図１の実線位置）。When a wave occurs, the weight 8 is slid on the wave-eliminating plate 7 to be positioned at one end, and the center of gravity of the wave-eliminating plate 7 is moved to one side. As a result, the wave-eliminating plate 7 has the apex 6a.
With the fulcrum as a fulcrum, the side on which the weight 8 is located descends and the other side rises and inclines (solid line position in FIG. 1).
【００１４】その結果、上昇した側の消波板７の端が海
上に突出し、波が生じる位置に障害物として存在し、波
の進行を阻害し、波を砕波して消波作用をなす。As a result, the end of the wave-dissipating plate 7 on the ascending side protrudes above the sea and exists as an obstacle at the position where the wave is generated, which obstructs the progress of the wave and breaks the wave to perform a wave-dissipating action.

の注水量を制御し浮力を調整するようにした。In the first embodiment, the weight 8 is used as the means for inclining the wave-eliminating plate 7, but in the second embodiment shown in FIG. 2, the weight 8 is rotated to the other end of the wave-eliminating plate. A pouring / draining chamber 11 is provided for this purpose, and the buoyancy is adjusted by controlling the amount of pouring water into the pouring / draining chamber 11 by a pump or the like (not shown).

全部を海中に位置させる。As a result, when the wave is quiet, the pouring / draining chamber 11
As shown by the chain line position in FIG. 2 by reducing the amount of water, the wave-dissipating plate 7 is balanced at the apex 6a and held in a horizontal state, and all of them are positioned in the sea.
【００１７】波浪が生じたときは、注排水室11の水量を

点として下降し、他端が上昇し海面上に突出する。When waves occur, the amount of water in the pouring / draining chamber 11 is increased to reduce the buoyancy on the side where the pouring / draining chamber 11 is provided. As a result, the water discharge and drainage chamber 11 side of the wave-eliminating plate 7 descends with the apex 6a as a fulcrum, and the other end rises and projects above the sea surface.
【００１８】なお、第１、第２実施例ともに海上に突出
