Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a hydraulic surface power generation device. Background technique [0002] At present, most of the energy we use is fossil energy accumulated by solar energy for a long time. It is a non-renewable energy source. The distribution of fossil energy on the earth is uneven and the reserves are limited. In addition, in the process of using fossil energy, it will produce greenhouse gases that cause environmental pollution. affect the quality of life and health of human beings. [0003] There are also some renewable energy sources on the earth, such as wind energy, water energy, geothermal energy and tidal energy. Among them, wave energy is the cleanest renewable resource. Its development and utilization will greatly alleviate the crisis due to the gradual depletion of mineral energy and improve The damage caused by burning fossil energy to the environment. Wave energy is ...

AI Technical Summary

Problems solved by technology

[0004] Although the development potential of wave energy is huge, wave energy is a low-density, unstable, non-polluting, renewable, large-storage, widely-distributed, and difficult-to-use energy source. The main factors affecting the utilization of wave energy are: whether it can fully absorb waves energy; how to improve energy conversion rate; effective working time of power generation device; construction and operation cost

The current water surface power generation device has short effective working time, low energy conversion efficiency, and high manufacturing cost, so the utilization of wave energy cannot be put into commercial operation.
