Power generation device collecting wind energy through pitching-swinging coupled motion of flapping wings

Abstract

The invention relates to a power generation device collecting wind energy through pitching-swinging coupled motion of flapping wings. The power generation device comprises rocking arms, the flapping wings and magnetofluid generators. A telescopic device is hinged to the upper portion of each rocking arm, air cylinder structures rotating back and forth by cooperating with swinging motion of the rocking arms are arranged on the lower portions of the rocking arms, and a sealed chamber is arranged in each air cylinder structure. The flapping wings are movably arranged on the upper portions of therocking arms in a sleeving manner, and the other ends of the telescopic devices are hinged to one sides of the flapping wings. Each magnetofluid generator comprises a C-shaped permanent magnet, magnetofluid which is opposite to the C-shaped permanent magnet and is used for cutting a magnetic field and an electrode connected with the magnetofluid through a circuit. The C-shaped permanent magnets are arranged outside the air cylinder structures in a sleeving manner. The magnetofluid is arranged in the chambers, the magnetic fields generated by the C-shaped permanent magnets are cut in the process that the magnetofluid rotates back and forth along with the air cylinder structures, and therefore voltages and currents are generated and are output through the electrodes. According to the power generation device, the structure is simple and compact, power is generated by providing main power through wind energy, energy is saved, and effective power generation can be carried out.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a power generation device that utilizes the pitch-sway coupling motion of a flapping wing to collect wind energy. Background technique [0002] With population growth, economic development and social progress, people's demand for energy is increasing day by day, but traditional fossil energy is becoming exhausted day by day, and its mining cost and price will gradually increase. Therefore, the development and utilization of renewable energy is the theme of energy development at present and for a long time in the future. Renewable energy includes solar energy, wind energy, water energy (specifically referring to river water energy) and ocean energy, etc. Among them, wind energy is the second largest renewable energy after solar energy, with huge content and potential for large-scale development and utilization. The global wind energy reserves are about 2.84 trill...

Problems solved by technology

However, the fluid kinetic energy conversion technology and equipment based on traditional rotary turbomachinery also have certain limitations: rotary wing wind turbines can only be economically beneficial in stable high-speed wind fields, and current wind turbines can only collect energy close to the ground and Wind energy at sea level; large-diameter wind turbines can only be installed in uninhabited areas due to their high wing-tip speed due to their noise, and large-scale wind farms may even affect the migration of birds

These defects of rotary-wing wind turbines limit the in-depth development and utilization of wind energy, especially high-altitude wind energy.
