Abstract

The invention discloses a variable-pitch suspended blade device for capturing wave energy. The device comprises a suspended support, hydraulic motors, bolts, couplers, blade pieces and a drive hydraulic system. The hydraulic motors are arranged on the suspended support through the bolts and are connected with the blade pieces through the couplers. The drive hydraulic system comprises a hydraulic pump, an overflow valve, a one-way valve, a proportional valve, a filter and an oil tank. The hydraulic motors rotate under the action of the drive hydraulic system so as to adjust the rotating angle of the blade pieces through the couplers, and variable pitch of a suspended blade is achieved. The rotating angle of the blade pieces is reasonably adjusted, so that the matching relation between capturing efficiency of the suspended blade device and the wave energy is achieved, and the self-existent capacity of a suspended blade type wave-energy utilization device under extremely bad conditions like windstorms and typhoons can be improved.

Description
