Floating body rope pulley wave energy generating system

Abstract

The invention relates to a wave energy generating system. The system utilizes a floating body to receive the thrust of wave; a rope of which one end is tied on the floating body and of which the other end is wound on a rotating wheel pulls the rotating wheel to convert the obtained irregular wave thrust into rotating power; and at the stage of wave fall, the rotating wheel is driven by means of a spiral spring to reversely rotate so as to withdraw the rope. For a buoy lighthouse, the rotating wheel can be directly connected with a generator to rectify and store electricity; for large-scale wave energy generating, the floating bodies can be combined into an array plane, while the rotating wheel achieves energy transfer and collection through a ratchet and a hydraulic system; and finally, a generating set achieves electricity generation. The system is suitable for the waves of most waveforms, can absorb wave energy with high efficiency, has strong wave resistance and low manufacturing cost, and does not need to depend on a shore base to work.

Description

technical field [0001] The invention belongs to the field of ocean wave power generation. Background technique [0002] The current wave energy conversion system usually has two parts: the first part is the acquisition system, which is used to capture wave energy; the second part is the conversion system, which converts the captured wave energy into a specific form of mechanical energy or electrical energy. The forms of the acquisition system include oscillating water column (OWC), oscillating float (Buoy), pendulum (Pendulum), duck (Duck), raft (Raft), contraction ramp (Tapchan), clam (Clam) etc. The techniques to improve the amount of wave energy capture include the wave gathering technology through wave diffraction or refraction, and the inertial wave gathering technology through the resonance between the system and the waves. The conversion part includes air impeller, hydraulic system, low-head turbine, and generator, etc. The methods to improve conversion efficiency in...

Problems solved by technology

[0003] Although wave energy conversion devices are ever-changing, most of them are still unable to adapt to the ever-changing waves, and their ability to resist wind and waves is also poor. When the waves are small, the driving force for the part that absorbs wave energy is too small to reach Its rated effect, the absorption capacity is too poor, and when the waves are large, it often exceeds the working range of its wave energy absorbing device, resulting in damage to the system

[0004] Take the "sea snake" that is about to be put into commercial operation as an example. When the wavelength of the wave is smaller than the length of each section, the effect of the wave on each section is almost the same. absorb wave energy

If the 1 / 4 wavelength of the wave is greater than the total length of the sea snake, although the wave height of the wave becomes larger, the waveform becomes flatter, so it still cannot effectively absorb the wave energy
