Problems solved by technology

The existing suspension pendulum structure is all one-piece, does not have the function of pitch adjustment, and cannot adjust the matching relationship between capture efficiency and wave energy
When the wave energy exceeds the design output power of the suspended pendulum type wave energy utilization device, especially in extreme conditions such as storms and typhoons, the existing integrated suspension pendulum will bear huge wave force, which will easily cause the suspended pendulum type wave Exploitable Device Destruction

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

technical field [0001] The invention relates to a suspension pendulum device for capturing wave energy, in particular to a suspension pendulum device with variable pitch. Background technique [0002] The suspended pendulum wave energy utilization device is a typical coastal engineering device, which can absorb ocean wave energy, convert it into electrical energy or realize seawater desalination, and has high wave energy conversion efficiency. The hanging pendulum is the core component of this wave energy utilization device, and the wave energy can be captured through its swing under the action of waves. The existing suspension pendulum structures are all integrated, do not have the function of pitch adjustment, and cannot adjust the matching relationship between capture efficiency and wave energy. When the wave energy exceeds the design output power of the suspended pendulum type wave energy utilization device, especially in extreme conditions such as storms and typhoons, ...
