Flapping-wing energy-acquiring device of self-moving flaps

Abstract

The invention relates to a flapping-wing energy-acquiring device of self-moving flaps comprising an energy-acquiring part, flapping wings and a main shaft, wherein the two flapping wings are connected to each other by the main shaft to form a whole; the main shaft of the two flapping wings is positioned through the middle of the energy-acquiring part; the two flapping wings can rotate around the main shaft and the whole can make a heaving motion in a vertical direction; and the energy-acquiring part acquires the energy transmitted by the flapping wings by the movement of the main shaft. The Gurney flaps are applied in the flapping-wing energy-acquiring device of the self-moving flaps. According to Archimedes' principle, the Gurney flaps are designed to be arranged at the trailing edge of airfoils to automatically change the direction based on different directions of the heaving motion, which is equivalent to increasing the camber of the airfoils, thereby increasing the lift coefficient of the airfoils and the energy-acquiring efficiency of the flapping wings. The flapping-wing energy-acquiring device of the self-moving flaps is simple in structure, and automatically realizes the direction changing of the self-moving flaps on the surface of the airfoils based on the different directions of the heaving motion by using Archimedes' principle.

Description

technical field [0001] The invention relates to a flapping wing energy harvesting device, in particular to a flapping wing energy harvesting device using a Gurney flap. Background technique [0002] In science and engineering, humans often draw design inspiration from the natural world. Human beings have successfully designed some miniature bionic aircrafts by imitating the flapping propulsion movement mode of birds, fish and aquatic animals. Inspired by birds flying in groups, fish swimming in groups and countercurrent movement, humans have discovered that flapping wings can not only be used for propulsion and improve maneuverability, but also can obtain energy from vortices, free surface waves or free incoming currents. [0003] The flapping wing is a mechanism for simulating the propulsion or energy capture of birds, fish and aquatic animals. Such as figure 1 As shown, the existing flapping wing energy-capturing device using flexible airfoil, the force analysis of the ...
