DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings.

FIG. 1 shows a flotation wave device according to a first embodiment of the present invention.
A pair of wave-dissipating main bodies 1 which are formed of a connecting structure floating on the water surface W in a substantially inverted V shape and whose opposite ends are rotatably connected by a hinge H, and the wave-dissipating bodies connected to each other. Inside of the pair of wave-dissipating main bodies 1, and traction members 2 and 2 each having one end connected to a free-side end of the main body 1 and the other end connected to an anchor A installed on a water bottom B. And an auxiliary body 3 disposed in the.

The wave-dissipating main body 1 and the auxiliary body 3 are each made of a material that floats on the water surface W or a structure that floats on the water surface W. As shown in FIG. It is formed of a hollow box.

Further, the wave-dissipating main body 1 has a frame 4 inside thereof.
Has a plurality of chambers 6 partitioned and formed by partitioning plates 5 connected to each other. Inside each of the chambers 6, a synthetic resin pipe 7 having a different diameter, which is a buoyant body, is attached to impart buoyancy. There is.

The synthetic resin pipe 7 is made of an inexpensive synthetic resin material such as a vinyl chloride pipe and is formed into a pipe shape. The specific gravity of the synthetic resin material is assumed to be that which floats on water. Since the wave-dissipating main body 1 can be provided with sufficient buoyancy, and the chamber 6 has a pipe-like shape.
A large amount of air can be enclosed inside, and greater buoyancy can be given to the wave-dissipating body 1.

Furthermore, the synthetic resin pipe 7 is resistant to corrosion due to water immersion and is easy to replace. The above room 6
In order to fill the void generated by mounting the synthetic resin pipe 7 therein and to give a greater buoyancy to the wave-dissipating body 1, the void may be filled with the foamed resin material 8 as shown in FIG. it can.

Each wave-dissipating body 1 thus constructed has its opposite end rotatably connected by a hinge H, and the free end of each wave-dissipating body 1 has the other end anchored. Since one ends of the traction members 2 and 2 connected to A are connected and floated on the water surface W in a substantially inverted V shape, the traction members 2 and 2 can be extended substantially vertically. As a result, the installation width of the anchor A can be set to be as narrow as the fixed breakwater.

The auxiliary body 3 is used as an auxiliary when the buoyancy of the wave-dissipating main body 1 is insufficient, and is formed in a substantially triangular prism shape, and like the wave-dissipating main body 1, a material or structure that floats in water. It is configured by a body, and by forming a weight portion 3a at the lower end portion thereof, it is configured so as not to turn over at the water surface W.

Therefore, when the buoyancy of the wave-dissipating body 1 is sufficient, it is not necessary to use the auxiliary body 3, but the auxiliary body 3
Has a function of holding the wave-dissipating body 1 in an inverted V-shape, so it is desirable to mount it between the wave-dissipating bodies 1 in advance.

When the auxiliary body 3 is provided inside each of the wave-dissipating main bodies 1, broken lines in FIG. 1 prevent the auxiliary body 3 from flowing out between the wave-dissipating main bodies 1. As shown in the figure, stopper pieces 1a may be connected to both end portions of the wave-dissipating main body 1, and the auxiliary body 3 may be replaced with a wire rope or the like in place of the stopper pieces 1a. Is connected to each wave-dissipating body 1 or the top of the auxiliary body 3 is hinged H
You may connect to.

As shown in FIG. 4, when the waves collide with each other, the wave-dissipating main body 1 thus constructed cancels the waves while being inclined further downstream by the impact of the waves. At this time, the auxiliary body 3 adheres to the inside of one of the wave-dissipating main bodies 1 as shown in FIG. It acts so as to return to the inverted V-shaped standing state shown in FIG.

Further, in the floating wave canceling apparatus according to this embodiment, as shown in FIG. 5, the wave becomes abnormally high due to a typhoon or the like, and this floating wave canceling apparatus cannot be expected to have a sufficient wave canceling effect. Not only that, when there is a risk that the floating wave canceller may be damaged, since the length of each traction member 2 is set in advance to a constant level, the wave canceling main body 1 is submerged in water and is protected from wind and waves. The influence can be avoided. Of course, each pulling member 2 can be wound / unwound by a motor (not shown) which is rotated by remote control, so that it can be submerged in high waves.

FIG. 6 shows a second embodiment of the present invention, in which the floating wave canceller is constructed so that four wave cancellers 1 are connected to each other to improve the wave canceling effect. There is.

That is, the floating wave canceling apparatus according to this embodiment hinges the opposite ends of each of the four breaking wave bodies 1, 1, 9 and 9 formed of a material or a structure floating on the water surface W. Each of the pulling members 2 and 2 is connected to each other by H and suspends one end of each of the pulling members 2 and 2 on a roller 10 arranged on one side surface of each of the wave-dissipating main bodies 1, 9, 1 and 9. The other end is connected to each anchor A installed on the water bottom B.

Therefore, in this embodiment, each traction member 2,
By suspending one end of the wave-dissipating body 1 from the water-dispersing bodies 1 and 9 by suspending it on a roller 10 disposed at one of the upper and lower ends on the outer side of the wave-dissipating body 1 and 9, Can effectively dissipate waves over a wide range up to.

In the above embodiment, the case where the wave-dissipating main body 1, 1 or the wave-dissipating main body 1, 9, 1, 1, 9 is arranged upright in the inverted V shape by the hinge H is described as an example. However, the present invention is not limited to such a form, and three or more pairs of wave-dissipating main bodies may be connected to each other and connected by a hinge H.

FIGS. 7 and 8 show a third embodiment of the present invention. In this embodiment, the wave-dissipating body 1, 1 or the wave-dissipating body having the structure of the first and second embodiments is shown. The reflection convection prevention plates 11 and 11 for waves are connected to the main bodies 9 and 9 via a hinge H, and one end of each of the pulling members 2 and 2 is connected to the reflection convection prevention plates 11 and 11. By doing so, it is possible to perform wave-dissipation in a wider range, and when the installation site is a site where the water depth is shallow, such as a shallow water,
Other configurations and operations are the same as those in each of the above-described embodiments except that the reflected convection prevention plates 11 and 11 attenuate the reflected waves generated by the wave elimination to further improve the wave elimination effect. Therefore, the drawings are denoted by the same reference numerals as those in the above-described embodiments, and detailed description thereof will be omitted here.

[0024]

As described above, according to the present invention, the installation width of the anchor for pulling the wave-dissipating body is fixed when installing the floating-wave canceller for floating on the water and effectively attenuating the wave. Since it can be installed as narrow as
It is safe even when a ship, etc. sails near the wave-eliminating body, and the wave-eliminating effect of the wave-eliminating body can be sufficiently obtained.
It has an excellent effect.

Further, according to the present invention, the auxiliary body formed in the shape of a triangular prism is provided at the inner top of the wave-dissipating main body installed in the inverted V shape, so that the water surface is formed in a substantially inverted V shape. There is also an effect that it is possible to stably install the wave-dissipating body that is floated and installed.

Further, according to the present invention, by connecting the reflection convection upper plate to the wave-dissipating main body, when the floating wave-eliminating device is installed in a portion where the water depth is shallow, such as a shallow water, it is caused by the wave-dissipation. The reflected waves from the bottom of the water can be effectively attenuated, and the wave-dissipating effect can be further improved.
