Vertical wind power generator

Abstract

A tower structure for vertical wind-driven generator is composed of three or more sets of support bars, wherein each set of support bar is vertically upward and in the same circle, and the center of the circle is the center of the tower structure; a frames and a wind wheel arranged on the frame is provided on the tower structure; the wind wheel comprises a rotation shaft and three or more leaf blades arranged on the rotation shaft, the rotation shaft is perpendicular with ground level and is the center of the circle; the leaf blade comprises a supporting rack and at least two movable plates arranged on the supporting rack, the movable plates are connected together in series via a tension bar, the up and down movement of the tension bar switches the movable plates between opening state and closing state, and the tension bar is arranged supporting rack and perpendicular to the wind wheel. The generator may not easily cause the damage of the rotation shaft, so as to prolong the service life thereof. The tower can be firmly arranged on the ground, so that the tower will not be inclined and fallen down to hurt of staff and damage of equipments. The invention also has the advantages of long service life and convenient repairing and maintenance.

Description

technical field [0001] The invention relates to a vertical wind power generator. Background technique [0002] With the development of society, energy is becoming more and more important and scarce in people's life, which has attracted the attention and attention of all walks of life, and various new energy sources have been developed one after another. Applications include hydropower, tidal power, wind power, solar energy, etc. Currently used wind power generators, such as Chinese Patent No. CN02143472.7, a vertical shaft multi-dimensional wind power generator, is composed of wind blades, generators, and iron frame, and the shaft is erected and connected with the generator or gearbox. The rotating shaft is equipped with fan blades. The fan blades are stacked and arranged by moving blades, and wind collecting plates are arranged around them. The movable blades are connected horizontally by connecting plates and have vibration damping pads. The frame and the shaft are connec...

AI Technical Summary

Problems solved by technology

However, since the supporting iron frame of this kind of vertical-shaft multi-dimensional wind generator is installed on the lower part of the wind blade, it is prone to toppling over when encountering strong winds during work, causing the danger of personnel and equipment damage

And because the rotating shaft is only fixed at its lower end by an iron frame, and the fan blade is arranged on the upper end of the rotating shaft, it causes the fan blade to be unstable during work, which is easy to cause damage, which will reduce its service life, and is also inconvenient during use repair and maintenance
