In addition to horizontal axis tidal current turbine and vertical axis tidal current turbine, domestic
and foreign researchers have proposed many other types of tidal current energy generation device.
The introduction is as follows.
(1) Oscillating hydrofoil tidal current energy device is represented by the “Stingray” designed by
EB Company, as shown in Figure 4. The main working part of the oscillating hydrofoil tidal current
energy device is hydrofoil which is connected on the turbine through the main arm. When the water
flows, the hydrofoils will lift up, causing the main arm swing up and down. This action makes the
mechanical energy into electrical energy
