Title:
TAIL FIN TYPE POWER GENERATION DEVICE EMPLOYING BIDIRECTIONAL ROTATION OF FLOW INDUCED VIBRATION MEANS TO CAPTURE OCEAN CURRENT ENERGY
Document Type and Number:
WIPO Patent Application WO/2022/110859
Kind Code:
A1
Abstract:
Disclosed is a tail fin type power generation device employing bidirectional rotation of a flow induced vibration means to capture ocean current energy. The device comprises a fixed frame, a flow induced vibration plate and clutches. A through shaft extends through the flow induced vibration plate. The clutches are respectively arranged at two ends of the through shaft. The clutches are connected to a power generation structure by means of a transmission structure. The present invention uses a flow induced vibration plate as a blunt body over which an ocean current flows. When the ocean current flows over the blunt body, the vibration plate rotates bidirectionally, and thus is subjected to a relatively small resistance force in the current. A surface of the plate is provided with a corrosion-resistant coating, thereby reducing corrosion to the plate, and extending the service life of the device under water. The present invention is additionally provided with overrunning clutches, such that regardless of whether the vibration plate rotates clockwise or counterclockwise, the clutches can rotate to drive a power generator coil to cut a magnetic induction line so as to generate power. The invention ensures that regardless of whether a plate operating underwater rotates clockwise or counterclockwise, clutches can rotate therewith, such that ocean current energy can be captured to a greater extent, thereby obtaining more energy.
