Problems solved by technology
The supporting floating body of the device will reflect waves on the wave-facing surface, resulting in a decrease in the wave energy that can be captured by the collecting floating body; at the same time, since the collecting floating body and the supporting floating body are semi-submerged floating bodies, the destructive effect of the motion of the two will also reduce the energy of the device. wave energy conversion efficiency

The invention relates to a float-type wave-energy converting device. The float-type wave-energy converting device comprises a supporting-guiding device, a collecting float assembly, a compensation float, a hydraulic pump and a hydraulic-energy extracting device. The bottom of the supporting-guiding device is directly anchored on the seabed, and the top of the supporting-guiding device comes out of the sea surface. The collecting float assembly is arranged on the supporting-guiding device in a sliding and sleeving mode and floats on the sea surface. The compensation float is fixedly arranged outside the supporting-guiding device and is located below the collecting float assembly. The hydraulic pump is fixedly arranged in the supporting-guiding device. The hydraulic-energy extracting device is arranged inside the bottom of the supporting-guiding device. The compensation float is used for improving the wave capturing ability of the collecting float assembly. A piston of the hydraulic pump is connected with the collecting float assembly and used for converting the wave energy captured by the collecting float assembly into fluid hydraulic energy. The hydraulic-energy extracting device is communicated with a cylinder body of the hydraulic pump through a water inlet main pipeline and a water outlet main pipeline, so that the hydraulic energy provided by the hydraulic pump is used for power generation and sea water desalination.
Description
technical field [0001] The invention relates to a wave energy conversion device, in particular to a float type wave energy conversion device. Background technique [0002] With the continuous development of the world economy and the rapid expansion of population, the energy supply of traditional fossil fuels such as coal, oil and natural gas can no longer meet people's production and living needs. At the same time, environmental pollution problems such as greenhouse effect, acid rain and smog caused by fossil energy is also getting worse. In order to alleviate the looming energy crisis and environmental pollution problems, countries all over the world have gradually turned their attention to the inexhaustible marine renewable energy. Among them, ocean wave energy has the advantages of high grade, high energy flow density, and can be mined day and night. Since the 1970s, people have begun to use wave energy. [0003] At present, wave energy utilization devices at home and a...
