  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The wave energy mitigation device according to the present invention includes a large number of high-compression air pipes 1 capable of press-fitting compressed air, and a high-compression air generation press-fitting pump 4 for injecting compressed air from both ends of the high-compression air pipe 1. In particular, in the high-compression air pipe 1, a plurality of jet outlets 2 of compressed air press-fitted into the pipe are arranged in parallel in the length direction at a predetermined interval.

  And each jet nozzle 2 of the said high compressed air pipe 1 is equipped with the jet nozzle cap 3 which opens and closes the said jet nozzle 2 according to the height of the air pressure in the said high compressed air pipe 1.

  As shown in FIGS. 2 to 7, the spout cap 3 according to the present embodiment has a bottomed hollow in which the opening top portion 32 is connected so as to surround the spouts 2 arranged in parallel with the highly compressed air pipe 1. A cap main body 31 having a plurality of through holes 34 (outlet openings) formed in the peripheral wall 33, a valve seat 36 that is built in the cap main body 31 and communicates with the spout 2, and is built in the cap main body 31. A floating valve 37 is a spherical floating ball that can freely move up and down in water and can be seated on the valve seat 36.

  In the present embodiment having the above-described configuration, as shown in FIGS. 1 and 9 to 12, a large number of high-compressed air tubes 1... The high compressed air pipe row 15 is formed in parallel in the intersecting direction. Further, the high compressed air generating press-fitting pumps 4 and 4 connected to both ends of each of the high compressed air pipes 1 forming these high compressed air pipe rows 15 for press-fitting compressed air are, for example, as shown in FIG. They are placed on land such as capes along specific sea areas 5.

  At this time, as shown in FIG. 3, the jet cap 3 provided in the high compression air pipe 1 laid on the seabed or in the sea has a buoyancy caused by a float valve 37 (floating ball) in the cap body 31 according to the depth water pressure. , And is seated on the valve seat 36 to close the spout 2. Then, compressed air is press-fitted from the high-compressed air generating press-fitting pumps 4 and 4 so that the float valve 37 (floating ball) in the cap body 31 is not pushed down, and the air pressure in the high-compressed air pipe 1 is kept constant. .

  When storm surges, high waves, and tsunamis are suspected, the air pressure in each high-compression air pipe 1 forming the high-compression air pipe row 15 is raised all at once after warnings, warnings, and signal transmission notifications. When the pressure is increased to a level higher than the water pressure, the float valve 37 (floating ball) built in the cap body 31 of the spout cap 3 installed at each spout 2 formed on the bottom surface 11 side of the high-compressed air pipe 1 is as shown in FIG. Compressed air that is pushed down downward simultaneously by the air pressure applied from the jet outlet 2 connected to the valve seat 36, separates and settles from the valve seat 36, and jets out of the jet outlet 2 with the jet outlet 2 open. As shown in FIG. 11, a plurality of through holes 34 (outlet openings) formed in the cap body 31 are diffused and released into the sea at a stretch, and as shown in FIG. 11, the bubble group rises and the specific sea area 5 becomes a bubble-filled sea area. To do.

  Accordingly, as shown in FIG. 8, the wave 12 having high mass transport energy 13 that is successively pushed toward the bubble-filled sea area absorbs energy by compressing the bubble 10 (reference numeral 14: when the bubble is compressed). Wave energy absorption amount), the wave that pushes to the specific sea area 5 is mitigated and cut off in the bubble-filled sea area, so when it reaches the coast, the mass transport energy 13 is mitigated, so the power declines. It can contribute to 18 disaster prevention mitigation.

  As described above, the present embodiment can prevent or reduce damage caused by storm surges, high waves, and tsunamis in the coastal area 18 in advance. Compressed air is injected to keep the air pressure in the high-compressed air pipe 1 constant, and the float valve 37 (floating ball) in the cap body 31 is not pushed down to prevent the compressed air from being ejected. As a result, the ship can not only be navigated without being affected by the high-compressed air pipe 1 laid in the specific sea area 5, but also can be navigated in the high-compressed air pipe 1 when storm surges, high waves, and tsunamis are anticipated. A bubble-filled sea area is formed without adding time by simply adding compressed air necessary for the floating valve 37 (floating ball) built in the cap body 31 of the spout cap 3 to be released into the compressed air that has been press-fitted in advance. Door has the advantage that it can be.

  In addition, high-compressed air generation press-fitting is performed at normal times by deploying appropriate locations such as the shape, material, scale capacity, quantity, etc. of the facilities with high-compression air pipes according to the sea area, depth, and shape environment of the specific sea area 5 to be installed.
