Embodiment Construction

[0114] Further description will be given below in conjunction with the accompanying drawings.

[0115] Section I: The rope-controlled hydraulic cylinder wave generator of the present invention includes a wave energy acquisition and conversion system (ie WEC), a rope control device, and a gravity anchor. The WEC is located on the water surface and is connected to the gravity anchor through the rope control device below it; the rope control device It includes two components with controllable relative motion, namely the frame and the slender member. When the frame is on the top and the slender member is on the bottom, the top of the frame serves as the connection point with the WEC, and the bottom end of the slender member serves as the connection with the gravity anchor. When the frame is on the bottom and the slender member is on the top, the frame acts as the connection point with the gravity anchor, and the top of the slender member acts as the connection point with the WEC.

Abstract

The invention relates to a wave-activated generator with a line-operated hydraulic cylinder. The generator comprises a wave energy absorption and transformation portion, a line controlling device, and a gravity anchor, wherein the wave energy absorption and transformation portion comprises a floating body and a hydraulic system. A hydraulic oilcircular path of the hydraulic system comprises a single-acting cylinder, an exit one-way valve, a high pressure accumulator, a hydraulic motor, a low pressure accumulator/ an opening oil box, an oil filter, and an admission one-way valve. A cylinder body of the single-acting cylinder is connected with the floating body, and a lower end of a piston rod of the single-acting cylinder is connected through a rope or a chain with a upper end of a rack of an actuating mechanism of the line controlling device which is under the floating body. The rope controlled by the line controlling device extends downwards to be connected with the gravity anchor. According to the system, the hydraulic cylinder which has limited range can adapts to big wave and tidal changes, the effect of rope coiling is good, and the efficiency of rope coiling is high.

Description

technical field [0001] The invention relates to a wave power generation system, which belongs to the field of wave power generation. Background technique [0002] CN 103104408 A is the prior art closest to the present invention, but has many problems, such as spring fatigue of the rope control device, small rope retracting force, unbalanced tension when suspended in water, deflection of the rope control actuator, rope winding, and waterproofing. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a rope-controlled hydraulic cylinder wave generator, which can make the hydraulic cylinder with limited stroke suitable for large waves, adapt to tidal changes, have good rope retraction effect and high wave height utilization rate. [0004] Technical scheme of the present invention: [0005] Section I: A rope-controlled hydraulic cylinder wave generator: including a wave energy acquisition and conversion system (Wave EnergyConverter, hereinafter ...
