Description

  The present invention reduces natural disasters such as typhoons, El Niños, hurricanes, and tsunamis caused by earthquakes, and improves the shortcomings of conventional tetrablocks and long one-piece breakwaters to fully cope with collisions of huge tsunamis. The present invention relates to a wave-reversing induction curved column water channel structure and its arrangement structure.

  Structures such as water turbine generators that generate power using ocean currents, tidal currents, waves, and river water currents include vertical start-shaft turbines, conventional horizontal start-shaft turbines, and other Savonius and Darius wind turbines. There are applied water turbines, and for horizontal start-up water turbines, there are various types such as screw-type water turbines with generators installed instead of ship engines, submarine-type propeller-type water turbines or power generators, torpedo-type water turbines, and skipping-type water turbines. There is a water wheel. There is also an example where a narrow strait is further reclaimed and narrowed, and the flow of the sea current is increased to obtain a high-speed propeller rotation. Both horizontal and vertical start-shaft turbines are single-shaft structures that have advantages and disadvantages, and technical research is ongoing. Efficient offshore power generation structures using these water turbines and techniques for using such structures as wave breakwaters have not yet been found.

  Also, in the long term, the Earth's rotation speed is gradually slowing down mainly due to tidal friction (friction between seawater and seabed caused by tides), and the National Aeronautics and Space Administration (NASA) It is known in reports such as. In order to adjust the atomic clock according to the delay of the earth's rotation speed, “leap seconds” are inserted and adjusted once every few years. Natural energy possesses enormous energy enough to slow down the rotation of the earth, and effective utilization of this enormous natural energy is the main subject of the present invention, and tidal friction is reduced by effectively utilizing such natural energy. It has not been proven, though it contributes to prolonging unforeseen obstacles due to the slowing down of the Earth's rotational speed.

  The present inventor has continued to be interested in and thought about power generation structures that use natural energy including ocean currents, tidal currents, and waves. I applied and got a patent (see Patent Document 1). Although the present invention is common to the above-described invention in that it uses natural energy, it is based on a technical idea completely different from the concept of a conventional water wheel.

Japanese Patent No. 4260546

  Large waves and tsunamis have huge acceleration and water pressure, and if they are on a breakwater block (caisson) such as a tetra block or a long, single-shaped breakwater, the impact force when colliding is immense. When a huge tsunami collides with a breakwater with a high tetrablock stack or a single-shaped breakwater, if the wave enters the gap of the tetrablock or the base of the single-shaped breakwater and becomes full, it floats underwater due to buoyancy. It became clear by the huge tsunami caused by the Great East Japan Earthquake that the block and the single-shaped breakwater easily collapsed and spilled out due to the impact of pushing up and did not play a role as a breakwater. It has been found that the inner curved surface portion of the inverted guiding curved column waterway structure in the power generation structure of the present invention can be applied as a substitute for a breakwater block or a single-shaped breakwater by facing the tidal current / water flow direction. The main purpose of the present invention is to reduce natural disasters such as typhoons, El Niño, hurricanes, and tsunamis caused by earthquakes, which are said to be caused by solar energy. An object of the present invention is to provide a breakwater reversal-inducing curved column waterway structure and its arrangement structure that can sufficiently cope with a case where a huge tsunami collides by improving the breakwater of this shape.

  In order to solve the above-described problems, the present invention is configured so that at least one surface of the first curved columnar structure portion and the second curved columnar structure portion are directed forward or upward in the same direction on both curved surfaces. Thus, the first curved column structure portion is overlapped with the curved surface portion of the second curved column structure portion with a gap serving as a water channel, and the height of the second curved column structure portion behind the first curved column structure portion is higher than the height of the first curved column structure portion. It is set as the wave-reversal inductive curved surface column waterway structure characterized by integrating so that it may become high.

  In order to solve the above-mentioned problems, the present invention provides a first curved shape of the wave-reversal-inducing curved surface column waterway structure constructed in a substantially U-shape, a substantially inverted shape or a curved shape in plan view. It is preferable to provide an arrangement structure of a wave-reversal-inducing curved column waterway structure characterized by alternately placing gaps in a stepping stone shape or a dotted shape so that the face column structure faces offshore.

The wave-reversing induction curved column waterway structure of the present invention reduces natural disasters such as typhoons, El Niños, hurricanes, and tsunamis caused by earthquakes, and improves the shortcomings of conventional tetrablocks and long one-piece breakwaters to create huge tsunamis Even if there is a collision, it will be possible to respond sufficiently.
Further, the wave-reversing induction curved column waterway structure of the present invention is arranged in a stepping stone shape on the bottom slope of the sea, and has the effect of preventing natural disasters such as tsunamis by causing waves to collide with each other and consuming wave power. .

It is a longitudinal cross-sectional explanatory drawing of the wave-reversal inductive induction curved column water channel structure of this invention. It is explanatory drawing which shows the example of arrangement | positioning of the wave-reversal inversion induction | guidance | derivation curved surface column waterway structure of this invention.

  Next, modes for carrying out the present invention (hereinafter referred to as “embodiments of the present invention”) will be described with reference to the drawings. However, the present invention is not limited by the embodiment of the present invention.

  The wave-reversing inductive curved column water channel structure XZ of the present invention includes the invention described in claim 1, and as shown in FIG. 1, at least one of two large and small curved column structures formed on a curved surface. The parts X and Z are integrated structures configured such that both the curved surfaces X1 and Z1 face forward or upward in the same direction, and the channel Y is formed on the curved surface Z1 of the large second curved columnar structure portion Z. The first curved columnar structure portion X is overlapped with a small tunnel-shaped gap, and integrated so that the height of the second curved columnar structure portion Z at the rear is higher than the height of the first curved columnar structure portion X. The wave-reversing inductive curved columnar channel structure XZ is installed so that the curved surface side faces the waves. For example, assuming that this wave-reversing inversion-induced curved column waterway structure is installed on the sea floor at a water level of 15 m and a high wave with a wave height of 15 m (water depth of 30 m) is repeatedly pushed, the lower water flow P30 of the first wave of waves and the upper The upper water flow P15 (0 to 15 m) is divided into two stages, and the lower water flow P30 flows into the tunnel-shaped water channel Y to become P31, and becomes P32 / P33 to rise the second curved surface Z1 behind.

  On the other hand, after the upper water flow P15 jumps on the first curved surface X1 to disperse the hydrodynamic force into the sky, it naturally falls behind the first curved surface X1 as P18 and partly rises as P19. However, since the water flows P33 and P34 fall onto the tops of the lower water streams P32 and P33 that are about to jump on the second curved surface Z, the flow velocity energy of the water flows is consumed and disappears due to the time difference, and the combined or disturbed water streams P34 and P35. Become. The water flow that could not jump on the first and second curved surfaces X1 and Z1 returns to the reversal water flow P20 and collides with the second wave water flow P40 to prevent the second wave water flow from advancing and reduce the wave force. Play. The wave height when the inverted water flow P20 and the second wave water flow P40 collide with each other represents a mark of the wave-dissipating effect. The water flows P36 and P37 that have crossed the second curved surface Z fall vertically, lose the impact force of the water flow, and complete the role of the breakwater. Furthermore, by providing a side groove Y1 on the ground in the vicinity of the back side of the curved columnar structure Z, water that has fallen vertically is temporarily stored, and wave propagation and water flow velocity are not consumed by blocking backward wave propagation. The effect of disappearing can be further enhanced.

  FIG. 2 shows an example of the arrangement of the wave-reversing induction guiding curved column water channel structure XZ according to the present invention. It is constructed in a letter shape or a curved shape, and the wave-dissipating inversion-induced curved column water channel structure XZ is alternately arranged in a stepping stone shape or a scattered dot shape so that the first curved surface column structure portion X faces offshore ( (See FIG. 2). By arranging in this way, the direction of the left and right wave water flows is induced, and the wave water flows collide with each other in front of each other at the central gap portion, cancel each other, or cause the wave flows to collide with each other to cause a wave-dissipating effect. First, an entrance levee (1) (H-shaped) is arranged off the center of the bay entrance, and the wave stream 1 is divided into the left and right. The wave stream 2 split to the left is again collided with the branch levee (2) and split to the left and right 4.5. The wave water stream 3 that has been diverted to the right is collided with the branch levee (3) and again diverted 6 and 7 to the left and right. Therefore, 5 and 6 collide and collide with the outlet bank (4) while attenuating the hydrodynamic force, and disappear while diverting to the left and right by 3 degrees. The reduction of the power of the tsunami by placing obstacles in a stepping stone like this is because the small islands scattered in the bay along the Matsushima Bay coast during the Great Tohoku Earthquake reduced the damage of the tsunami. it is obvious.

  Reduced natural disasters such as typhoons, El Niño, hurricanes and tsunamis caused by earthquakes, improved the defects of conventional tetrablocks, and collided huge tsunamis by building a stepping stone shape instead of a large tetrablock breakwater It is possible to cope with the situation well, and it can be greatly expected as a disaster prevention structure in the face of the occurrence of a huge earthquake.
