うことができる。It is called [7]. As shown in Figure 6,
It can be seen that the water on the left side of node (6) passes through plane (A) and comes to the position shown in Figure 4. Therefore, it can be said that on the plane (A), the water particles are moving horizontally (8) as shown in FIG. As can be seen, by locating the pendulum plate (3) at the position of the surface (A), efficient absorption of wave energy becomes possible. By the way, since the wavelength of waves is always wide, and the back plate (2) is fixed, it is impossible to always align the node (6) with the pendulum plate (3). Therefore, in some cases, wave energy is absorbed inefficiently. An object of the present invention is to provide a wave power absorbing caisson that can always efficiently absorb wave energy regardless of the wavelength of the wave. In order to achieve the above object, the present invention provides a caisson whose front and rear surfaces and top surfaces are open, and in the waterway formed by this caisson, a pendulum plate for absorbing wave energy that is linked to a hydraulic pressure generator is disposed. A back plate whose distance can be changed with respect to the pendulum plate is provided behind the pendulum plate. With such a configuration, the node can always be aligned with the position of the pendulum plate by adjusting the distance of the back plate relative to the pendulum plate according to the incoming wavelength. Hereinafter, one embodiment of the present invention will be explained based on FIGS. 6 and 7. GO is a caisson with open front and rear surfaces and the top surface, and V is for the bottom wall) and V is from the left and right side walls. 114, with a waterway inside. A pendulum plate Q3) for absorbing wave energy is disposed at the front of this waterway, and the rotational axis t14) of this pendulum plate 03) is interlocked with a hydraulic pressure generator 115) K provided on the caisson 00. At the rear of the pendulum plate 03), a plurality of grooves (16A) (16
B) (16C) (16D) are formed in the vertical direction, and these 1m (16A016B) (16C') (16D)
Back plate (17A) that can be inserted and removed separately from VC and C top
X17B) (17C) (17D) are provided. Backboard(
For insertion and removal of 17AX17B) (170X17D), use the cylinder device it (18A) (18B) (18CX18D)
These cylinder devices (18A) (
18B) (18C) (18D) are written several times on the frame 09). When the incident wave (20) enters the waterway of the caisson aIj, if the wavelength is CIJ, the relationship with the distance [b] from the pendulum plate field to the back plate of *I/c1 is [τ = b')1. At this time, the water particles at the position of the pendulum plate 03) will perform a reciprocating horizontal movement. Therefore, the °C distance [b] is corrected according to the change in wavelength (1), but the correction is made by inserting all the back plates corresponding to the distance [b] mentioned above, and removing all the back plates in front of the relevant back plate. Just put it out. Detection of wavelength (1) is performed as follows. In other words, a row of hydraulic needles is installed on the seabed, and temporal changes in water depth are detected using electrical signals. This signal is the measurement line 1 that crawls on the ocean floor.
22 and is sent to the measurement meter on the ground. The measurement meter plots this data in the relationship between time and water level.
At the same time, the computer 1241VC transfers the data. At this time, the computer analyzes the water level data taking into account the standard water depth of the water pressure gauge υ and the characteristics of the shore, and calculates the wavelength C1 of the waves observed at the location of the water pressure gauge. calculate. Then, in the above-mentioned embodiment, back plates (17A) (17B) (
17CX17D) is inserted and removed using the cylinder device (18A) (1
8B) (18C] (18D), but this may also be done with a chain block, etc. Also, it may be configured such that the back plate is one piece and has four multi-movements in the direction of the waterway. 11. Measurement of W1 of length C1 may be performed by observing a wave and measuring the period of the wave with a stopwatch. According to the wave force absorption caisson of the present invention described above, the wavelength of the incoming wave At the same time, by adjusting the distance of the back plate to the pendulum plate, the nodes can be kept at one position on the pendulum plate.
1, and therefore, wave energy can always be absorbed efficiently no matter what the wavelength of the wave.
