When the wave is guided to the inlet pipe 67 of the generator 60 by the lifting of the truss 30, the seawater flowing through the inlet 62 of the generator 60 swirls along the generator body 61. The discharge port 63 is discharged.

When the seawater is strongly vortexed in the generator body 61 to rotate the wing 64 axially supported inside the generator body 61 by the strong flow pressure, the central axis of rotation by the rotation of the blade 64 When the 65 rotates, the power generation unit 66 generates power through the rotation shaft 65.

As described above, the present invention is very simple in construction and the waves and water caused by the water are always guided into the generator body 61 through the induction plate 67, so that the power generation is made stable by the swirl water. do.

On the other hand, if a strong typhoon is pushed from the sea, the generator 60 may be damaged together with the induction plate 67 by the typhoon, so if the typhoon starts to blow, the truss elevating motor of the truss elevating drive unit 40 is first shown in FIG. Drive 41 to raise the truss 30 as much as possible.

When the truss 30 is raised as much as possible, the generator 60 drives the generator rotation motor 52 in the motor housing 51 of the generator rotation driving unit 50 to be positioned above the upper end of the pillar 20. ) Rotates as shown in FIG. 9 in the reverse direction of the typhoon.

In this case, the generator 60 allows two generators 60 to be mounted on one truss 30 between two pillars 20, and these generators 60 rotate in opposite directions to each other.

As shown in FIG. 10, when the induction plate 67 of the generator 60 is rotated to the opposite side to the typhoon, the generator 60 is lowered by a typhoon again by lowering the truss 30 to a constant height as shown in FIG. 11. Keep it safe.

Therefore, the damage of the generator 60 can be prevented as much as possible, and the power generation efficiency is further increased by using a more powerful rotational force by the swirling effect of sea water.
