Empennage type ocean current energy flow-induced vibration bidirectional rocking power transmission device

Abstract

The invention discloses an empennage type ocean current energy flow-induced vibration bidirectional rocking power transmission device which comprises a fixed frame, a flow-induced vibration plate andclutches, a through shaft is arranged in the flow-induced vibration plate, and the clutches are arranged at the two ends of the through shaft; and the clutch is connected with the generator structurethrough a transmission structure. The flow-induced vibration plate is selected as the streaming bluff body, when ocean current bypasses the bluff body, the vibration plate swings in two directions, the resistance borne by the plate in water flow is small, the surface of the plate is provided with the anti-corrosion coating, corrosion to the plate can be reduced, and the underwater service life ofthe device is guaranteed. The overrunning clutch is added, no matter the vibrating plate rotates clockwise or anticlockwise, the clutch can rotate to drive a generator coil to cut a magnetic inductionline to generate electricity, it is guaranteed that when the plate works underwater, no matter the plate swings clockwise or anticlockwise, the clutch can rotate along with the plate, and therefore ocean current energy can be captured to a greater extent, and greater energy is obtained.

Description

technical field [0001] The invention relates to a power generating device, in particular to an empennage-type sea current energy flow-induced vibration bi-directional rocking power generating device. Background technique [0002] In today's deteriorating ecological environment, with the reduction of resource energy, the development and utilization of marine energy has been paid more and more attention. Ocean current energy has attracted much attention as the most readily available and continuously available energy in ocean energy. Flow-induced vibration is a common vibration phenomenon in nature. It means that when water flows through a solid, the shear stress causes the water flow near the wall to curl up into a vortex, which induces pressure changes in different regions of the solid surface, thereby generating alternating fluid forces, causing the solid to reciprocate. The phenomenon of movement. The phenomenon of flow-induced vibration widely exists in related engineeri...
