Technical Field
The invention relates to the technical field of power generation devices, in particular to a power generation device for collecting wind energy by utilizing pitching-swinging coupled motion of flapping wings.
Background
With the population growth, economic development and social progress, people have increasingly growing demand for energy, but traditional fossil energy is gradually exhausted, and the exploitation cost and price of the traditional fossil energy are gradually increased. The exploitation of renewable energy is therefore the subject of energy development today and for a considerable time in the future. Renewable energy sources include solar energy, wind energy, water energy (specifically river water energy), ocean energy and the like, wherein the wind energy is the second largest renewable energy source next to the solar energy, and the renewable energy sources have huge content and potential for large-scale development and utilization. The global wind energy storage is about 2.84 trillion, wherein the available amount is about 600 hundred million kW, which is about 10 times larger than the total amount of water energy which can be developed and utilized on the earth. The wind energy reserves in the world and China are huge, and the wind energy reserves are renewable energy sources which occupy the largest proportion and grow fastest at present. However, the actual utilization of wind energy is only a small part of the reserves, wherein the available wind energy resources account for less than 10% of the global wind energy reserves.
At present, human beings mainly use wind energy based on traditional rotating turbomachinery, and the rotating turbomachinery has obvious advantages in conversion and utilization of high-quality fluid kinetic energy. However, the fluid kinetic energy conversion technical means and equipment based on the traditional rotating turbine machinery also have certain limitations: the rotary wing fan has economic benefits only in a stable high-speed wind field, and the existing fan can only collect wind energy close to the ground and a layer of sea level; due to the fact that the wing tip speed of the large-diameter fan is high, the noise of the large-diameter fan can cause the large-diameter fan to be installed in an unmanned area only, and the large-scale wind power plant can even affect the migration of birds. These drawbacks of the rotary wing wind turbine limit the deep exploitation and utilization of wind energy, especially high altitude wind energy, by human beings. The development and utilization of high-altitude wind energy face huge technical challenges, and the development of efficient and compact power generation devices suitable for high-altitude wind energy collection gradually becomes the focus of attention of academic and engineering circles.
