Abstract
The invention discloses a multi-joint stretchable rod type wave power generation system which comprises a wave energy capture part, a hydraulic pump high-pressure storage part and a hydraulic expansion power generation part. The wave energy capture part is of a triune efficient capture structure composed of a supporting shaft, stretchable rods and a spheroid. The ellipsoid moves up and down under the wave action, and the stretchable rods are driven to pitch by using the supporting rod as the pivot and are stretched in the direction of the supporting shaft. A motion base point is formed by interaction of a supporting frame, a supporting ball and the supporting shaft. The stretching motion of the stretchable rods on the two sides of the spheroid is mechanically coupled through a conical gear, a change wheel, a ratchet wheel and a hydraulic pump, so that low-pressure oil is compressed and stored to a high-pressure oil tank. A hydraulic motor and a direct-current generator are optimally controlled through high-pressure oil under the cooperation of a flow valve, a Boost current transformer and an inverter, and efficient conversion from hydraulic energy to electric energy is achieved. The wave energy capture efficiency is effectively improved, the wave energy power generation application range is enlarged, and new-energy industry development is greatly promoted.
