Abstract

The invention discloses a direct-driven wave power generation device which comprises a buoy mechanism, a permanent magnet linear motor mechanism and a piston mechanism, wherein the buoy mechanism comprises a dynamic buoy and a stationary buoy; the dynamic buoy is arranged outside the stationary buoy in a sleeving manner; a support frame is fixed at the upper end of the dynamic buoy; the permanent magnet linear motor mechanism comprises a stator and a rotor; the rotor is arranged in the stator; the piston mechanism comprises a cylinder, a piston ring and an output shaft; the piston ring is mounted in the cylinder; the interior of the cylinder is divided into an upper cavity and a lower cavity; one end of the output shaft is fixed with the piston ring; the other end of the output shaft is fixed with the support frame; the lower cavity is communicated with an upper port in the stator in a sealed manner; a lower port of the stator is communicated with the upper cavity through a high-pressure pipeline in a sealed manner. The direct-driven wave power generation device, provided by the invention, is simple in structure and has the capability of resisting the storm at sea, and optimal capture of wave energy can be realized, so that the wave power generation efficiency is improved. The scale of the wave power generation device is variable, and wide application and popularization are facilitated.

Description

technical field [0001] The invention relates to a wave power generation device for extracting and utilizing ocean energy (wave energy), in particular to a direct-drive wave power generation device. Background technique [0002] At present, wave power generation technology, one of the utilization of ocean energy, is moving towards commercialization with great development prospects. Especially in today's situation where petroleum energy and coal energy are nearly exhausted, human beings in the world are facing many development problems, and they are looking forward to a greater technological breakthrough in wave power generation technology. However, due to the complexity of ocean wave energy, most wave power technologies are still in the experimental stage. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a direct-drive wave power generation device, which drives the permanent ...
