)(1) A hydraulic pressure generator (6) provided on the caisson (1) is actuated by a lever (5) interlocked with the lever (5). (7) shows a stopper, and (8) shows a wave. The pressure receiving plate (3) rotates and oscillates around the rotating shaft (4) in response to wave force, but at this time, due to the limitations of the O oil pressure generator (6), the pressure plate (3) rotates within a very limited range. Limited to agitation.

エネルギーの吸収効率を向上し得る。In order to achieve the above object, in the present invention, levers are connected to each other from a pair of front and rear shafts, a frame is attached between the lower ends of these levers so as to be relatively swingable, and a pressure receiving plate is hung from this frame, The present invention provides a wave energy absorbing device including a hydraulic pressure generating device interlocked with the intermediate portion of the lever. According to this configuration, the pressure receiving plate performs a near-horizontal motion that is compatible with shallow sea waves, so it can move sufficiently even when the wave height is small. In addition, as long as the wave height is not too large, there will be no restriction on hydraulic pressure (2) as long as the generator is made long enough.
If a stopper is required, it can also be installed above the water. In other words, energy absorption efficiency can be improved.
以下、本発明の一実施例を第２図〜第４図に基ついて説

当な位置に据え付けるものである。An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. An icehouse is installed in a caisson QO on the coast and installed at an appropriate location.

明は、この点を考えた機構となっている。If this caisson 01 does not have to serve as a wave break, it can be used in a waterway instead of an icehouse. Figure 3 (a) ~)
As can be seen in the figure, the trajectories of water particles in ocean waves are circular in the deep sea, and rapidly attenuate with increasing depth. However, as the water particles approach shallow water, they lose their elliptical orbit, and when we consider waves with long wavelengths on the coast like in this example, they move back and forth almost horizontally. Therefore, if the pressure-receiving plate 0]) that receives wave pressure moves horizontally, it will adapt to the trajectory of the water particles and absorb energy more efficiently. The present invention has a mechanism that takes this point into consideration.

Supported and fixed. In addition, the lever (1t9 (17

ルギーを吸収できることになる。Now, when a wave (E) enters the caisson icehouse or waterway, the pressure receiving plate 0υ moves due to the force of this wave, but in this mechanism, the pressure receiving plate 0υ reciprocates almost horizontally due to the link action of the lever QflQη. It turns out. In other words, the wave force acts on the frame (1) from the pressure receiving plate Oη, and the lever Q·0η swings left and right as a double pendulum as shown by the imaginary line in FIG. Here, since the axis uaa3 is fixed in position, the pressure plate 0])
Although it will move up and down somewhat, basically it will move horizontally. Therefore, the hydraulic pressure generating device W (b) is also moved horizontally with a slight relief, generating hydraulic pressure, which is extracted into the hydraulic motor via the hydraulic pipe (c). Hydraulic pipe @(c) Since the mechanism for converting this energy into air or heat can be constructed using any existing technology, the details thereof will be omitted. All of the above structures will be constructed on land, so there will be no underwater construction. Furthermore, if the water channel and the lever Qf9αη are made sufficiently long and the axle is positioned upward, the pressure receiving plate 0υ can be allowed to move considerably, and energy can be absorbed more efficiently.

In addition, it can be automatically controlled according to the tidal difference, and when abnormally large waves are expected, it can be raised in advance to avoid the risk of destruction.

In this case, when a very high wave suddenly hits, the hydraulic generator (

Therefore, energy absorption efficiency can be improved. Also, as long as the wave height does not become too large υ, as long as the hydraulic pressure generator is made long enough, there will be no restriction.
The pressure plate can move over a wide range. Furthermore, if a stopper is required, the entire device can be assembled on the water.
All underwater work can be eliminated.
