Oscillating airfoil generation device provided with turning angle amplifiers

Abstract

The invention provides an oscillating airfoil generation device provided with turning angle amplifiers. The oscillating airfoil generation device comprises two vertical supports, a blade, the two turning angle amplifiers, two connecting rods, a crank and a generator, wherein each vertical support is provided with a sliding rail; a slider sheathes each sliding rail; the end part of each slider is fixedly connected with a mounting rack of the corresponding turning angle amplifier; the mounting rack of the turning angle amplifier is provided with a pinion shaft, a reversing gear shaft and a large gear shaft; a pinion, a reversing gear and a large gear respectively sheathe each pinion shaft, each reversing gear shaft and each large gear shaft; the spindle of the blade penetrates through end part baffles and is fixedly connected with the two pinion shafts; one end of each of the two connecting rods is arranged on the corresponding large gear; the other end of each of the two connecting rods is pivoted with the corresponding crank; two ends of the crank are respectively provided with an inertia wheel, and one of the two ends of the crank are connected with the generator. According to the oscillating airfoil generation device provided by the invention, the blade can keep a comparatively ideal attack angle range within determined vibration amplitude, so that the energy collection efficiency is greatly increased.

Description

technical field [0001] The invention relates to a wind energy and tidal current energy generating device, in particular to a vibrating wing generating device equipped with a corner amplifier. Background technique [0002] Wind energy and tidal current energy are renewable energy sources with abundant reserves, clean and pollution-free. The development of such resources can effectively reduce the environmental pollution caused by the consumption of fossil energy and alleviate the increasing shortage of fossil energy. However, the energy conversion efficiency of some common energy conversion devices is low, which limits the effective use of renewable resources by humans. Therefore, the development of efficient and stable energy conversion devices is the core technology of wind energy and tidal current energy generation. [0003] At present, the mainstream transducer devices can be divided into vertical-axis turbines and horizontal-axis turbines according to their structural f...

AI Technical Summary

Problems solved by technology

The advantage of the vertical axis turbine is that it can use incoming flows from different directions, but it is difficult to control the rotation of the blades; the horizontal axis turbine uses propeller blades, which is stable in operation and more convenient for maintenance, but it is not conducive to the arrangement in areas with limited water depth
