Wave power generation device and system

Abstract

The invention relates to a wave power generation technology and particularly discloses a wave power generation device and system. The wave power generation device comprises a basic part, a rotary part, a swing arm, floating bodies, a hydraulic power storage piece and a hydraulic power generation module. The basic part is positioned in an applicable sea area. The rotary part is rotatably assembledon the basic part, and the middle of the swing arm is rotatably connected to the rotary piece. The two ends of the swing arm are connected with the floating bodies correspondingly, and a swing shaft of the swing arm is located on the water surface or slightly higher than the water surface. One end of the hydraulic power storage piece is connected to one side of the swing arm, and the other end ofthe hydraulic power storage piece is connected to the rotary piece. The hydraulic power storage piece is connected to the hydraulic power generation module through a hydraulic pipeline. Waves drive the two floating bodies of the swing arm to move up and down, so that the swing arm is driven to swing in a reciprocating mode; and reciprocating swing of the swing arm applies pressure to the hydraulicpower storage piece, and thus a high-pressure fluid is pumped to the hydraulic power generation module to conduct power generation. According to the wave power generation device and system, the structure is simple and reliable, and the energy conversion ratio is increased.

Description

technical field [0001] The present invention generally relates to a wave energy power generation technology, in particular, to a wave energy power generation device and a wave energy power generation system. Background technique [0002] In the development and utilization of ocean energy, various countries are actively exploring. The current wave energy generation devices have not yet been fully commercialized, and most of them are in the experimental stage, with limited energy conversion efficiency. In addition, due to the unstable motion characteristics and destructiveness of waves, the energy harvesting of floating bodies works in a sea state with great changes. Therefore, how to capture and convert wave energy safely and efficiently is a huge problem facing wave energy power generation technology. . Contents of the invention [0003] A main purpose of the present invention is to overcome at least one defect of the above-mentioned prior art, and provide a wave energy g...
