See Fig. 9 and Figure 12, when supposing that floating platform 6 is arranged in sea 5 wave 52 be movement from right to left and wave entry port 641 for perpendicular to paper.Now:
The wave 52 detected is flowed to information transmission to wave import transposition motor control unit 71 by wave flow direction sensor 72, wave import transposition motor control unit 71 makes rotational segment 69 turn to wave import 641 by wave import transposition motor 7 to meet to wave 52 namely towards the right side, make wave 52 can enter air chamber 64 through wave entry port 641 unobstructedly.When wave 52 enters air chamber 64 and strikes arc wave guide surface 644 under the leading role of arc wave guide surface 642, change into and go push piston 65 straight up.
See Figure 13 and composition graphs 9, suppose the original state of water bloking piece 82 as shown in Figure 10, current are to flowing according to the F in Figure 13, the current detected are flowed to information transmission to water bloking piece transposition motor control unit 84 by flow direction sensor 85, water bloking piece transposition motor control unit 84 makes water bloking piece 82 turn to for axle the side that meets water that water bloking piece 82 is blocked in radial-flow impeller 81 with running shaft 823 by water bloking piece transposition motor 83, and current can be produced uneven moment of torsion and rotate by diameter stream impeller 81.
