Abstract
The present disclosure relates to a device and a method for swinging power generation and vibration suppression by using arc-shaped wing plates with rough surfaces. The device consists of two parts, namely, a rotary swinging system and a collector system. The rotary swinging system includes a collector riser, steering bearings, nanometer material arc-shaped power generation wing plates, and flexible tail plates. The collector system includes telescopic power generation cylinders, a waterproof electric slip ring, and a waterproof power transmission line. The suppression of energy-consumption-free vortex-induced vibration is realized under the combined action that the nanometer material arc-shaped power generation wing plates divide a flowing space and adjust a flow direction, the nanometer material arc-shaped power generation wing plates drive the flexible tail plates to swing to destroy a tail vortex street, and hemispherical bulges and trumpet-shaped deflector holes disturb a boundary layer around flow.
