Cylindrical wind power generation device

Abstract

The invention discloses a cylindrical wind power generation device which comprises a cylinder body, a pipe shaft, folding blades, blade slide bars, blade bars, a semicircular track, a big gear, a generator and a small gear, wherein the pipe shaft is arranged at the circle centre position of a circular arc at the upper part in the cylinder body, and both ends of the pipe shaft extend out of the cylinder body, and the pips shaft serves as a transmission shaft of the big gear; both ends of the pipe shaft close to the inner wall of the cylinder body are provided with through holes, and a blade slide bar is respectively arranged in every through hole; the top ends of the blade bars and the blade slide bars are respectively in vertical fixed connection; both ends of every folding blade are respectively connected with the blade bars and the pipe shaft; the folding blades are unfolded at an air inlet to effectively absorb wind energy; and the folding blades are gradually compressed at an air outlet to effectively reduce resistance when the blades rotate. The cylindrical wind power generation device has simple and reasonable structure and wide application; is especially mounted on moving objects to obtain wind energy for electricity generation, such as automobiles, trains, ships, airplanes, and the like, and utilizes the speed of the objects to obtain wind energy.

Description

Technical field: [0001] The invention relates to a wind power generating device, in particular to a cylindrical wind power generating device. Background technique: [0002] Wind is a new energy source with great potential. There are about 10 billion kilowatts of wind power resources on the earth that can be used to generate electricity, which is almost 10 times the current hydropower generation in the world. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a year. Therefore, both at home and abroad attach great importance to the use of wind power to generate electricity. At present, the vast majority of wind generators are composed of two (or more) propeller-shaped impellers. Because the speed of the wind wheel is relatively low, and the magnitude and direction of the wind force are constantly changing, this makes the speed unstable. Because the wind directly acts on the blades, the pressure o...

AI Technical Summary

Problems solved by technology

Because the speed of the wind wheel is relatively low, and the magnitude and direction of the wind force are constantly changing, this makes the speed unstable. Because the wind directly acts on the blades, the pressure on the blades is increased, which may easily cause damage to the blades and affect the performance of the wind turbine.
