Patent ID: 8590298

Claim:
A changeable damping wave power capturing device driven by a bidirectional screw rod assembly, comprising: an elevator floating body; a water-proofing outer barrel assembly, comprising at least one water-proofing outer barrel including a channel, and connected to the elevator floating body; the bidirectional screw rod assembly, comprising a ball screw nut, a ball screw shaft, and a shaft, wherein the ball screw nut is connected to the water-proofing outer barrel, the ball screw nut is movably disposed on the ball screw shaft for performing a relative motion on the ball screw shaft, and the shaft is connected to the ball screw shaft; a reverse pawl-ratchet wheel assembly, comprising a reverse pawl-ratchet wheel, a first ring-shaped active gear, and a reverse ratchet pawl positioned within the first ring-shaped active gear, wherein the reverse pawl-ratchet wheel assembly connects to the shaft, and the first ring-shaped active gear comprises at least one internal reverse recess for accommodating the reverse ratchet pawl; a forward pawl-ratchet wheel assembly, comprising a forward pawl-ratchet wheel, a second ring-shaped active gear, and a forward ratchet pawl positioned within the second ring-shaped active gear, wherein the forward pawl-ratchet wheel assembly connects to the shaft, and the second ring-shaped active gear comprises at least one internal forward recess for accommodating the forward ratchet pawl; a first gear assembly, engaged with the first ring-shaped active gear and the second ring-shaped active gear, and comprising a first idle gear, a first slave gear, and a second slave gear; a first generating set, comprising a first generating set rotation shaft connected to the first slave gear and the second slave gear; and an accommodating device, comprising at least one hole, at least one guiding sliding sleeve, and an accommodating region, wherein the water-proofing outer barrel and the ball screw shaft pass through the hole, and the guiding sliding sleeve prevents water from leaking from a seam position of the water-proofing outer barrel and the hole.
