Reciprocating oscillation flapping energy conversion device

Abstract

The invention discloses a reciprocating oscillation flapping energy conversion device. The device comprises a frame, a flapping wing, a dip angle adjusting device, two slide blocks, two slide columns, a connecting rod mechanism, a small belt wheel, a controller, and a power generation device; the two slide columns are respectively fixed at two ends of the frame; the two slide blocks are respectively sleeved on the two slide columns to form slide pairs; the flapping wing is connected with the two slide blocks through a flapping wing rotating shaft; the dip angle adjusting device is a servo motor connected with the flapping wing rotating shaft; limiting blocks are arranged at the middle parts of the slide columns; position inductors are respectively arranged at the tops and the middle parts of the slide columns; the slide blocks are connected with the small belt wheel through the connecting rod mechanism; the up-down sliding of the slide blocks is converted to the rotation of the small belt wheel through the connecting rod mechanism; the small belt wheel is connected with the power generation device through a belt; signals of the position inductors are all accessed into the controller; and the controller controls the flapping wing rotating shaft to rotate through the servo motor so as to change an attack angle of the flapping wing. The device is simple in structure, is high in energy conversion efficiency through transmission of the slide pairs and connecting rods, and is low in loss.

Description

technical field [0001] The invention relates to the field of wind power, and relates to an oscillating wind power generation device that converts reciprocating linear motion into rotational motion, and in particular to a reciprocating oscillating flapping wing energy conversion device. Background technique [0002] The phenomenon of oscillating flapping wings exists widely in nature and engineering practice.
