  • Patent number: 11739728
    Abstract: A wave receiving mechanism includes: a shaft driving a hydraulic pump; and a wave receiving member including an arm and wave receiving plate, the arm unrotatably attached to the shaft, the plate being at the arm receiving a wave force, the wave receiving member swinging about the shaft by receiving the wave force and turning the shaft turn. The arm includes first and second arm portions, and a bendable portion, the first arm portion unrotatably attached to the shaft, the second arm portion being at the plate, the bendable portion coupling the first and second arm portions. When a swing angle of the first arm portion is less than a first predetermined angle, the bendable portion makes the arm portions swing integrally. When the swing angle of the first arm portion is the predetermined angle, the bendable portion allows the second arm portion to bend relative to the first.

  • Patent number: 11008999
    Abstract: A wave power generation system includes a wave receiving member, ram cylinder hydraulic pump device, change value sensor, accumulator device, hydraulic motor, power generator, and controller. The member is arranged near a virtual reflection surface that reflects a coming incident wave. The controller sets a torque command used when the generator generates electric power. Based on a differential value of a change value detected by the sensor and changes in accordance with a swing amount of the member, the controller determines whether the member is swinging toward a first or second side in a swing direction. When the controller determines the member is swinging toward the second side by receiving force of a reflected wave reflected by the virtual reflection surface, the controller changes the torque command from the command set when the controller determines the member is swinging toward the first side by receiving force of the incident wave.
