本発明は、船舶の航行時における船体のＷＡＩＡれを軽
減するための装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for reducing WAIA drift of a ship during navigation.
船舶の航行時における船体の横揺れ軽減装置としては、
船体の両側に船体横揺れ抑制用フィンを回動可能にそな
えるようにしたもの（フィンスタビライザー）が、従来
から用いられており、船体の航走に伴いフィンに沿う外
水の流れにより同フィンに揚力が生じるのを利用して、
船体の横揺れを軽減することが行なわれている。As a device to reduce the rolling motion of a ship while sailing,
Fin stabilizers have been used in the past, with rotatable fins on both sides of the hull for suppressing hull roll. Taking advantage of the lift generated,
Efforts are being made to reduce the rolling motion of the ship.
ところで、このような従来の船体横揺れ軽減装置の場合
、船舶の低速航行時にはフィンのまわりの流速が小さい
ので、フィンの揚力が不足して、船体の横揺れを十分に
軽減できなくなるという問題点がある。By the way, in the case of such conventional ship roll reduction devices, when the ship is traveling at low speed, the flow velocity around the fins is low, so the lift of the fins is insufficient, making it impossible to sufficiently reduce the ship roll. There is.
しかしながら海洋硬究船等は観測作業時には、低速航行
する場合が多く、作業能率や安全上の問題から低速航行
中の横揺れ軽減は是非とも必要である。However, oceanographic research vessels often navigate at low speeds during observation work, and it is absolutely necessary to reduce rolling during low-speed navigation due to work efficiency and safety issues.
そこで、低速航行時においてもフィンによる効果を十分
に得られるようにするため、フィン翼の面積を増加させ
ることなどが考えられるが、この場合、フィンが大型化
し、高中速での通常航行時の船体抵抗の増加を招くこと
になる。Therefore, in order to obtain the full effect of the fins even during low-speed navigation, it is possible to increase the area of the fin blades, but in this case, the fins will become larger and the This will lead to an increase in hull resistance.
本発明は、上述の酩点に鑑みて、通常航行時のフィンに
よろ船体抵抗の増加を招くことなく、船舶の高中速航行
時のみならず、その低速航行時においても、船舶の横揺
れを十分に軽減できるようにした船体ｍ揺れ軽減装置を
提供することを目的とする。In view of the above-mentioned problems, the present invention prevents the ship from rolling not only when the ship is traveling at high and medium speeds but also when the ship is traveling at low speeds without causing an increase in hull resistance due to the fins during normal navigation. It is an object of the present invention to provide a ship body sway reducing device capable of sufficiently reducing the sway.

付けられろとともに、同台板を回転駆動する台板回転駆
動機構が設けられたことを特徴としている。For this reason, the ship body roll reduction device of the present invention is provided with rotatable fins for reducing ship body roll on both sides of the ship body under the water surface, and a fin rotation drive lj! which rotationally drives the rotating wheel of the fin. The fins are mounted on a bed plate mounted inside the ship, and the bed plate is rotatably mounted on the ship's hull so that the fins can be rotated so that the wing tips of the fins are retracted during high-speed sailing. It is characterized by being provided with a base plate rotation drive mechanism that rotationally drives the base plate.

力、高中速での通常航行時には、フィンの翼端を後退さ
せて、フィンの鉛体抵抗を軽減させる。In the above-mentioned hull WA sway reduction device of the present invention, the fins are rotated together with the plywood by the plywood rotation drive mechanism, so during low-speed cruising, the fins are arranged perpendicular to the hull centerline to sufficiently reduce the sway of the hull. In order to ensure a large fin area, during normal navigation at high and medium speeds, the wing tips of the fins are moved back to reduce the lead resistance of the fins.
