長（ゆったりと張られていた。BACKGROUND OF THE INVENTION Most conventional floating breakwaters are moored with chains as shown in FIG. 3 in order to maintain their fixed position against the pushing force of waves. In the figure, (1) is a floating wave bank, (
2) is an anchor sunk to the seabed, and (3) is a floating wave bank (
The chain % (4) connecting 1) and anchor (2) is the floating wave bank (
1) is the wave that attacks. And in this case, the floating wave bank (
In order to prevent the chain (3) from breaking due to the movement caused by the wave (4) of 1), the chain (3) is generally large in diameter and is stretched fairly long (loosely stretched).
発明が解決しようとする問題点
しかしながら、このような従来構成によると、鎖（３）
の費用が浮消波堤（１）の設置費用に対して高い割合を
占めてしまうという問題があった。また、 ゛長い鎖
（３）を用いるため、専有面積がきわめて大きく、さら
に浮消波堤（１）の運動特性が変化しやすいので、最適
消波の設計が難しいという問題があった。Problems to be Solved by the Invention However, according to such a conventional configuration, the chain (3)
There was a problem in that the cost of this accounted for a high proportion of the cost of installing the floating breakwater (1). In addition, since the long chain (3) is used, the occupied area is extremely large, and the motion characteristics of the floating wave bank (1) are likely to change, making it difficult to design optimal wave dissipation.
本発明は上記問題点を解消した浮体の係留装置を提供す
ることを目的とする。An object of the present invention is to provide a mooring device for a floating body that solves the above problems.
問題点を解決するための手段
上記問題点を解決するため、本発明の浮体の係留装置は
、水上に浮く浮体を水底に係留する索体と、前記浮体の
周囲適所に波に対向して上下揺動自在に設けられ、波の

発生する翼とを有する構成とした。Means for Solving the Problems In order to solve the above-mentioned problems, the mooring device for a floating body of the present invention includes a mooring device for mooring a floating body floating on water to the bottom of the water, and a rope at appropriate places around the floating body up and down facing the waves. The structure includes wings that are swingable and generate propulsive force in a direction opposite to the direction of the waves due to the motion of the waves.
作 用
すなわち、翼によって浮消波堤を波の来襲方向と対向す
る方向に引っばるようにしたものであり、翼の質量等を
適当に選定することにより、浮消波堤を押す波の力の大
部分を相殺することが可能となるものである。In other words, the blades are used to pull the floating wavebank in the direction opposite to the direction in which the waves come, and by appropriately selecting the mass of the blades, the force of the waves pushing the floating wavebank can be reduced. This makes it possible to offset most of the
実施例 以下本発明の一実施例を図面に基づいて説明する。Example An embodiment of the present invention will be described below based on the drawings.
第１図において、（５）は海上に浮かして設けられた浮

定されている。（８）は浮消波堤（５）の波（９）来襲
側の面に波（９）に対向して上下揺動自在に設けられた
推進力発生用の翼、αＱ０は該翼（８）の両側と浮消波
堤（５）の両側とを連結する左右一対の連結棒７で。In Figure 1, (5) is a floating wave levee installed on the sea, (6) is an anchor sunk on the seabed, and (7) is a floating wave dyke (5) and an anchor (6). The chain (7) in this embodiment has a smaller diameter and considerably shorter length than the chain described in the conventional example, and is set to occupy a narrow area. (8) is a propulsive force generating blade provided on the wave (9) incoming side of the floating wave dyke (5) so as to be able to swing up and down facing the wave (9); αQ0 is the blade (8) ) and both sides of the floating wave bank (5) are connected by a pair of left and right connecting rods 7.

元の姿勢位置まで戻される。One end of each is connected to the floating wave bank (5) via a hinge, and the other end is connected to the wing (8) via a hinge with a rotating spring. Therefore, the wing (8) in the water has a connecting weight of 0 due to the attack of the wave (9).
It is rotatable in the vertical direction via the connecting rod α0
It can also swing up and down with respect to the surface. In addition, the hinge (to)
The rotary spring attached to the blade (8) is used to always maintain the wing (8) in a predetermined position (for example, horizontal position). α4 is an anchor sunk in the seabed directly below the wing (8), (to) is a rope connecting the anchor α4 and the hinge with rotation spring (to), and α is interposed in the middle of the rope (to). These springs function to always hold the connecting rod ao (6) in a predetermined position (eg, horizontal position). Therefore, the vertical rotation of the connecting rod αI (b) is restricted within a certain range, and the connecting rod α13 (11) is returned to its original position after the rotation.

能である。With this configuration, when a wave (9) approaches the floating wavebank (5), the wing (8) mainly swings up and down, causing the swing (
Vibration) Based on the principle of wing propulsion, a propulsion force is generated in the direction opposite to the direction of attack of the wave (9). Therefore, this propulsive force is transmitted through the connecting rod (to) ■ and pulls the floating wave bank (5), and most of the force of the wave (9) pushing the floating wave bank (5) is due to this. It will be canceled out. Hey,
The way the wing (8) swings can be freely changed by adjusting the mass of the wing (8) and the strength of the spring α and the rotating spring attached to the hinge (to). 5) The pulling force can be changed freely. Therefore, although in the above embodiment, the floating breakwater (5) and the anchor (6) are connected by the chain (7), it is theoretically possible to omit these.
次に、第２図に基づいて上記原理の説明を行う。Next, the above principle will be explained based on FIG.

である。これが揺動（振ｍ）翼推進力の原理である。That is, the present invention utilizes the thrust generated when the blade (8) swings (vibrates), and generates waves (9) as shown in the figure.
) has momentum in the vertical and horizontal directions, so the wings (8) are moved in the vertical direction by the energy in the vertical direction, creating a backward flow. In other words, the effect is the same as that of a fan. This is the principle of oscillating wing propulsion.

洋構造物に同構成が適用で握ることは明らかである。In addition, according to the above configuration, a connecting rod uO■ is attached to the hinge (2).
If a rotation spring is attached to keep the boat in a predetermined position, the anchor α, rope (end), spring αe, etc. can be omitted, and it can be used at great depths of water. Further, although the explanation has been given using the floating breakwater (5) as an example, it is clear that the same configuration can be applied to general marine structures.
発明の効果
以上本発明によれば、浮体の係留に用いる鎖の径が小さ
くできるとともに長さもかなり短くすることができる。Effects of the Invention According to the present invention, the diameter of the chain used for mooring a floating body can be made small, and the length can also be made considerably short.
したがって、経費削減右よび専有面積の削減を図ること
ができる。また、浮体の運動特性があまり変化しないの
で、最適消波等の設計が比較的容易に行うことができる
。Therefore, it is possible to reduce costs and exclusive area. Furthermore, since the motion characteristics of the floating body do not change much, it is possible to design optimal wave dissipation and the like relatively easily.
