らずしも蛇腹状でなくともよい。 In Figures 1 and 2, 1 is a floating body;
On the outer surfaces of a pair of side walls of this floating body 1 that are parallel to each other and orthogonal to the direction of wave propagation (arrow direction in Figure 1),
Fixed plates 2 and 3 are fixed. At the lower ends of these fixed plates 2, 3, there are rotating shafts 4, 5 along the horizontal direction.
Bearings 6 and 7 are fixedly supported to rotatably support the movable plates 8 and 9, and lower ends of movable plates 8 and 9 are fixed to the rotation shafts 4 and 5, respectively. the fixed plates 2, 3 and the movable plate 8,
9 are connected by bellows-shaped first bags 10 and 11, and springs 12 and 13 are interposed between the upper ends. A bellows-shaped second bag body 14 is provided on the inner surface of the side wall of the floating body 1, and communicates with the first bag body 10, 11 through the side wall and holes (not shown) in the fixing plates 2, 3. One end of the second bag body 14, 15 is fixed, and the other end of the second bag body 14, 15 is fixed to the closure plate 16, 1.
It is blocked by 7. The first and second bags 10, 11, 14, 15 are made of rubber or soft synthetic resin, and are filled with a fluid such as water or air.
has a smaller cross-sectional area than the first bags 10 and 11.
Reference numeral 18 denotes a fluid handling device installed in the floating body 1, and cylindrical parts 18a and 18b protrude from both sides thereof, and are fitted into the cylindrical parts 18a and 18b in a watertight and slidable manner. The tips of the pistons 19 and 20 are fixed to the closing plates 16 and 17.
The fluid operating device 18 is equipped with a hydraulic fluid circuit having a switching valve and a check valve, and transmits the movement of one of the pistons 19, 20 to the other. The water surface without waves is shown in phantom lines in Figure 1. Note that instead of using the springs 12 and 13, small floating bodies may be attached to the movable plates 8 and 9.
Furthermore, the movable plates 8 and 9 may be rotated about their upper ends, or the upper and lower ends may be connected to the fixed plates 2 and 3 by springs without using the rotation shafts 4 and 5. Furthermore, the bags 10, 11, 14, and 15 do not necessarily have to be bellows-shaped.

できる。 Due to the waves in the direction of the arrow (FIG. 1), one of the movable plates 8 receives wave pressure, and one of the first bags 10 expands and contracts. Since the first bag body 10 and the second bag body 14 are in communication with each other, the second bag body 14 expands and contracts in accordance with the expansion and contraction of the first bag body 10. Piston 19 is pushed or pulled. The movement of this one piston 19 is transmitted to the other piston 20 by the fluid operating device 18, whereby the other second and first bags 15 and 11 expand and contract, and the other movable plate 9 moves to create waves. do. In other words, one movable plate 8
Using the wave energy received by the other movable plate 9
By creating waves, the floating body 1 is not subjected to wave forcing, and therefore the wave influence can be significantly reduced.

である。 In addition, the above method is mainly carried out when the floating body 1 is stationary, and during navigation, the movable plate 8,
Although it is desirable to be able to store the 9 out of the way, this can also be done while underway.
また浮体1の代わりに水中の固定構造物に適用
