At present, the way of ocean energy development and utilization is mainly power generation.
There are two main ways to utilize the wave energy in the prior art:
(1) australian seafloor floating generator: as the waves from the sea surface impact the buoy, energy is transferred by the displacement of the buoy, squeezing the sealed seawater into a pipeline passing under the seabed to a hydroelectric power station on shore. The collected high pressure seawater drives turbines to produce electricity which can also be used for desalination. The zero-emission energy can provide partial electric power for hydropower stations and seawater desalination plants, and is beneficial to producing more energy and fresh water resources. And the second type is: the buoy fluctuates in the waves and the hydraulic pump on the seabed circulates the fluid in a closed loop, which has a total length of about 3 km and extends to the electricity generating facilities on the shore.
(2) Scotland underwater turbine generator: the turbine is mounted on the seabed and generates electricity from tidal energy, similar to a wind turbine, which has 3 blades and a pitch system, and a yaw system for turning the turbine 180 degrees as the tide changes direction.
The Australian seabed floating type generator utilizes vertical displacement of sea waves as power, a rotating water energy generator is converted into electric energy, the utilization rate of the sea waves is low, the power generation efficiency is greatly influenced by the sea waves, if the vertical displacement of the sea waves is small, the power generation efficiency is low, in addition, the occupied area is large, and the application range is limited.
