Automatic following wind power generation device

Abstract

The invention provides an automatic following wind power generation device which comprises a wind wheel, a power generator, a rotating rod, an iron tower and a tail rudder. The automatic following wind power generation device is characterized in that a rotating wheel disc is further included, the rotating wheel disc comprises a fixing part and a rotating part, the fixing part fixes the rotating wheel disc on the iron tower and is provided with a rotating bearing, an outer sleeve of the rotating bearing is fixed on the fixing part, the rotating part is fixed on a shaft of the rotating bearing and provided with two fixing lugs and a vertical rotating joint shaft, the rotating rod is provided with an installation hole matched with the vertical rotating joint shaft, the vertical rotating joint shaft penetrates through the installation hole to install the rotating rod on a horizontal rotating wheel disc, the weights of the two ends of the installation hole are same, and four or more than four even tail rudder vanes are uniformly distributed on the tail rudder in equal angle. According to the automatic following wind power generation device, the receiving orientation of the wind wheel can be regulated according to the wind direction, energy conversion is achieved at the highest efficiency, and automatic, intelligent and efficient wind power generation can be achieved on the condition of not adding any energy sources.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generation device that automatically follows the wind direction. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. [0003] Convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy, which is wind power generation. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. According to the curren...

AI Technical Summary

Problems solved by technology

When the wind blows to the blade, the aerodynamic force generated on the blade drives the wind wheel to rotate, but most of the wind power generators on the market are fixed, with a single orientation. We know that the ground wind does not flow in a fixed parallel horizontal plane. The wind rotor cannot receive the maximum frontal pressure of the wind in a vertical plane, which affects the efficiency of the wind rotor in receiving wind energy, and cannot maximize the use of wind power generation resources
