Description

発明の詳細な説明Detailed Description of the Invention

本発明は、停泊時等における船舶の波による揺れを軽減させるものである。The present invention reduces the shaking caused by the waves of a ship at the time of berthing or the like.

従来の船舶の減揺装置では、水中に安定板を設けたり、錘や水を移動させて船舶を水平にバランスを保つ工夫か見受けられる。  In the conventional ship vibration reduction device, it can be seen that a stabilization plate is provided in the water or a weight or water is moved to keep the ship in a horizontal balance.

発明が解決しようとする課題Problems to be solved by the invention

単純な構造で船舶の大小にかかわらず効果的に波による揺れを軽減出来ようにする事。  A simple structure that can effectively reduce shaking caused by waves regardless of the size of the ship.

課題を解決するための手段Means for solving the problem

本発明は、前記課題を解決するために、次のような手段を採用した。貫通した筒を船から水中に沈める様に該筒の下側の開口部から水を入れながら垂直に降ろせるようにすると伴に降ろした該筒の上側部を前記船に固定して一体化させるようにしたことで該船の上下移動の縦揺時には一体となった前記筒の水中部分の中の水が自由に出入りするため抑制しないが前記筒が振り子の様な横揺れとなる横移動の場合には該筒が水を切る抵抗力と該筒の中に留まっている水自体の重量により横移動が抑制されることになり水上の前記船の横揺れも軽減させるようにしたことと該船が発進の際には前記筒を水中から引上げて進行出来るようにした技術手段を採用した。
次に、貫通した筒を船から水中に沈める様に該筒の下側の開口部から水を入れながら垂直に降ろした前記筒の上側開口部に開閉自在の蓋を設け該筒を水中に垂直に降ろした後に前記蓋を閉じて密閉出来るようにした事で前記筒内の水が下部の開口部から流失し難くなり波による上昇揚力に対しても該筒内の水の重量により抑制されることで水上での前記船の縦揺れも軽減する事か出来るようにした技術手段を採用した。The present invention employs the following means in order to solve the above problems. As the penetrating cylinder can be lowered vertically while putting water from the lower opening of the cylinder so as to be submerged in the water, the upper part of the lowered cylinder is fixed and integrated with the ship. As a result of this, when the ship moves up and down, water in the underwater part of the integrated cylinder freely enters and exits, so it is not suppressed, but the cylinder moves sideways like a pendulum. In that case, the lateral movement is suppressed by the resistance force that the cylinder cuts water and the weight of the water itself that remains in the cylinder, and the roll of the ship on the water is also reduced. And when the ship started, the technical means was adopted so that the cylinder could be lifted from the water and proceed.
Next, an openable / closable lid is provided at the upper opening of the cylinder, which is lowered vertically while pouring water from the lower opening of the cylinder so that the penetrating cylinder is submerged from the ship, and the cylinder is perpendicular to the water. Since the lid can be closed and sealed after being lowered, the water in the cylinder does not easily flow out from the lower opening, and the lift due to waves is suppressed by the weight of the water in the cylinder. Therefore, the technical means that can reduce the pitching of the ship on the water was adopted.

発明の実施の態様を実施例にもとづき図面を参照して説明する。
図１、図２、は本発明の筒（１）を船（Ａ）の中央部に設けたもので、図１は筒（１）をロープ（７）で船（Ａ）に引上げた実施図で、図２は逆に水中に降ろした実施図であるが筒（１）の中に内側筒（２）が設けてあり図２の様に水中で二段にて長く延ばして降ろすことが出来るため横揺れを更に抑制出来るようにしたものである。
図３、図４、は本発明の筒（１）を船（Ａ）の両横の前後の計４箇所に設けたもので、水中に降ろしている実施図であるが、更に筒（１）の上側開口部に蓋（３）をして筒（１）の上部を密封している為、筒（１）の中の水中部分の水が筒（１）内に留まり、その留まった水の重量により縦揺れも抑制することになり船（Ａ）への荷物の搬入等がスムーズに出来るようにしたものである。Embodiments of the present invention will be described based on examples with reference to the drawings.
FIGS. 1 and 2 show the case where the cylinder (1) of the present invention is provided at the center of the ship (A), and FIG. 1 shows an embodiment in which the cylinder (1) is pulled up to the ship (A) by a rope (7). FIG. 2 is an embodiment in which the tube is lowered into the water. However, the inner tube (2) is provided in the tube (1), and the tube can be extended in two steps in water as shown in FIG. Therefore, the roll can be further suppressed.
FIGS. 3 and 4 show the pipes (1) according to the present invention provided at a total of four locations on both sides of the ship (A), and are lowered into the water. Since the upper opening of the cylinder is covered with a lid (3) and the upper part of the cylinder (1) is sealed, the water in the water in the cylinder (1) stays in the cylinder (1), and the retained water The weight is also suppressed by the weight, so that it is possible to smoothly carry the cargo into the ship (A).
