One end of the cable 53 is connected to the counterweight 63 in the vertical downward direction. In the initial state, the wave-encountering cylinder 51 is coaxially arranged on the support platform. When the wave exerts a horizontal force on the concave surface 52, the wave-encountering cylinder 51 slides in the support platform. The position of the wave-encountering cylinder 51 is offset, and the cable 53 is synchronously pulled to move to compensate for the position difference caused by the offset. When the cable 53 is pulled, the counterweight 63 is moved in the channel 62. When the horizontal force weakens or disappears, the cable 53 is pulled in the reset direction under the action of the gravity of the counterweight 63. Thus, the cable 53 is reciprocated in the specified direction. The runner can be arranged at the second input end 22 to collect the reciprocating movement of the cable 53.

[0040] Reference Figures 1-3 As shown in the embodiment, the support platform includes a top platform 41 and a bottom platform 42, and the top platform 41 and the bottom platform 42 are provided with annular blocking strips 43 on the outer peripheries of the opposite surfaces, the wave-encountering cylinder 51 is installed in the two annular blocking strips 43 through sliding rings 54, the diameter of the sliding ring 54 is smaller than the diameter of the annular blocking strip 43, and the diameter of the wave-encountering cylinder 51 can be greater than the diameter of the annular blocking strip 43 to obtain greater wave acting force of the concave surface 52; in the initial state, the sliding ring 54 is coaxial with the annular blocking strip 43.

[0041] Reference Figure 3 As shown in the embodiment, the sliding ring 54 is located in the middle region of the support platform, and the sliding ring 54 can move freely along the radial direction towards the center or the periphery in the top platform 41 and the bottom platform 42.

[0042] Reference Figure 3 and Figure 5 As shown in the embodiment, a plurality of through holes 44 are formed in the side wall of the annular blocking strip 43 in the circumferential direction, a guide rod 45 is arranged in each through hole 44, one end of the guide rod 45 is movably connected with the sliding ring 54, and the other end of the guide rod 45 extends out of the through hole 44; when the sliding ring 54 moves, the guide rod 45 moves along the through hole 44 to guide the stability of the movement of the sliding ring 54.

When the wave action force and the axis direction of the through hole 44 exist deviation, the swing block 46 swings to adjust the moving direction of the guide rod 45.

[0044] When the wave exerts a horizontal force on the concave surface 52 of the wave-encountering cylinder 51, the wave-encountering cylinder 51 is pushed to move in the top platform 41 and the bottom platform 42 through the sliding ring 54, and the guide rod 45 is pulled to move in the two swing blocks 46. The guide rod 45 moves linearly in the same direction as the wave action force, and the guide rod 45 deviates from the action force, which drives the two swing blocks 46 to deviate in angle.

[0046] When the wave action force deviates from the guide rod 45, the wave-encountering cylinder 51 moves under the force, pulls or pushes the guide rod 45 to move, and the guide rod 45 first presses the swing block 46 to deviate. The guide rod 45 with a large angle deviation also presses the air bag 48 through the swing block 46, so that the air bag 48 deforms and expands outward to form a avoiding space, so that the swing block 46 is displaced to compensate for the deviation, so that the guide rod 45 can move smoothly in the swing block 46; and when the action force is weakened or disappears, the air bag 48 resets the swing block 46, and a torsional spring can also be arranged on the rotating shaft to reset the rotating shaft.
