A frequency-adjustable swing-type wind power generation equipment

Abstract

The present application provides a frequency-adjustable swing-type wind power generation equipment, including a wind energy receiving device, a vibrating pole, a power generating device, a supporting device, a frequency adjusting device, a base, and the like. The wind energy receiving device absorbs the kinetic energy flowing through the air, and uses the Karman vortex street effect generated by the air flowing through the object to form a periodic swing; the vibrating rod connected to the wind energy receiving device transmits the kinetic energy to the power generation device for power generation; the power generation device targets the Karman vortex street With the characteristics of small amplitude and high frequency, the arrangement of magnetic poles is specially designed, so that the coil can cut the magnetic field with higher efficiency under smaller amplitude, and improve the frequency of power generation efficiency; the adjustment device adjusts the natural frequency of the wind energy receiving device according to the wind speed to make it vibrate Keep it near the maximum amplitude, so as to obtain the maximum wind energy conversion efficiency. The invention can supply power for small household appliances, and can also supply power for small independent electrical devices such as measuring instruments in remote mountainous areas.

Description

technical field [0001] The invention relates to the field of wind power generation, and provides a swing-type wind power generation device that can adjust its own natural vibration frequency according to the wind speed. Small independent electrical devices such as measuring instruments in mountainous areas are powered. Background technique [0002] When the wind bypasses the bluff object, the left and right sides of the wake of the object will generate pairs of antisymmetric vortex Karman vortex streets that are arranged alternately and rotate in opposite directions. The Karmen vortex street produced by the wind is also a form of transformation of wind energy. In recent years, with the development of technology, there have been some devices that use the Karman vortex street generated by the wind to generate electricity. However, this technology is still in its infancy, and there are few types of power generation equipment used. It has disadvantages such as poor adaptabilit...
