5, 14, 15, and seawater guiding blades 2, 12 and 3, 13 for guiding sea surface waves to the seawater inflow / outflow ports 10, 11. In addition, the wave power tidal power generation device of the present invention sandwiches both sides by the column 1 with the slit 19, which can be moved vertically and not horizontally, so that it is not swept away by the reciprocating motion of the sea surface wave 8 and is placed halfway on the sea surface. Leave fixed and floating.

As shown in FIG. 1, the water turbine 16 of the wave power tidal power generator according to the present invention has a seawater inflow / outflow port 10 so that it always rotates in the same direction even when a sloping wave and a squeezing wave from the opposite rush. The position of 11 is designed such that one is provided above the turbine and the other is provided below the turbine. When a diverging wave (a wave from the left in this figure) hits the power generating device of the present invention, the diverging seawater is guided to the seawater inflow / outflow port 10 at the upper part of the turbine 16 by the seawater guiding blades 2 and 12 at a high flow velocity. After being impelled by the water turbine 16 to rotate the water turbine 16 to the right, the water is discharged from the wake-side seawater inflow / outflow port 11 at the lower right of the water turbine 16.

Next, when a towing wave (a wave from the right in this drawing) hits the power generating apparatus of the present invention, the towing seawater is guided to the lower portion of the water turbine by the seawater guiding blades 3 and 13 at a high flow velocity. The water flows into the turbine side from the seawater inflow / outflow port 11, and after the turbine wheel 16 is similarly vigorously rotated rightward, is discharged from the seawater inflow / outflow port 10 at the upper left of the waterwheel.

8, the slider 18 can be moved up and down in the slit 19 by the column 1,
It cannot be moved in the horizontal direction.

The strut 1 needs to have sufficient strength to prevent the wave-tidal power generation device of the present invention from being swept away even when the giant sea surface wave 8 hits. Therefore, the base 20 for fixing the column 1 is installed on the seabed 21 with sufficient strength, and the column 1 is strongly towed from the left and right by the column fixing rope 7 to be strongly fixed to the seabed 21.

In FIG. 2, considering the case where the wind is blowing upward from the bottom, the wind is rectified and focused in the rotation direction of the wind turbine 23 by the wind guide blade 28 and the upper and lower wind focusing blades 29. After flowing into the wind inflow / outflow port 25 with a high flow velocity, the wind turbine blades 24 are urged and the wind turbine turbine 23 is vigorously rotated in the same direction (clockwise in FIG. 2). The air is discharged from the outlet 25 into the atmosphere. At this time, the generator 22 connected to the wind turbine 23 also rotates vigorously to generate power.
