Description

  The present invention relates to a wind power generator facility, and particularly relates to a vertical axis wind power generator that does not generate vibration during operation and is easy to install.

In recent years, the resurgence of the energy crisis has taken place due to soaring international crude oil prices, and scientists from various countries are proactively using new alternative energy (clean energy) such as solar energy, wind energy, tidal energy or biomass energy. Looking for.
Wind energy that has been used by mankind for thousands of years and has a history of thousands of years is widely used for agricultural irrigation and grain polishing, and wind energy is non-depleting and pollution-free renewable energy .
Currently, research and development techniques for wind power generators have been added, and the amount of power generated has been continuously improved, and the cost of wind power generation has been drastically reduced to the popularization range. Since it is possible, it can be installed in various places so as to meet the power supply requirements of each region, and the power supply cost is reduced by reducing the loss of power transportation.

The principle of a wind power generator is to convert wind kinetic energy into mechanical energy, and to generate electricity by changing the mechanical energy into the rotational motion of the generator.
Therefore, factors that affect the effectiveness of wind power generation include the height of the wind speed, the blade design of the wind power generator, the wind receiving area of the blade, and the like.
In addition, the wind power generator is roughly classified into a horizontal axis type (Horizontal Axis Wind Turbine) and a vertical axis type (Vertical Axis Wind Turbine) depending on the relative positional relationship of the rotation main axis with respect to the horizontal plane (ground).
Since the vertical axis wind power generator does not require a direction adjustment device, it works by using the drag that strikes an object in the direction of air flow, or by using the lift that the shape of an airplane wing receives due to the pressure difference between the top and bottom Therefore, it can be used for wind in any direction and has no dependency on the wind direction, but there is a problem that it is difficult to obtain effective power generation efficiency.

A conventional vertical axis wind power generator will be described with reference to FIGS. 1 and 2.
As shown in these drawings, the vertical axis wind power generator 10 includes a support rod 11. An impeller 12 is axially connected to the top of the support rod 11, and the impeller 12 has a plurality of different airfoil blades 121.
When the impeller 12 receives wind, the impeller 12 rotates and mechanically energizes the generator 13 at the bottom of the support rod 11 by the force generated by the drag applied to the blade 121 and the lift received by the blade 121. Rotating motion generates electrical energy.
Actually, one of the impellers 12 is mounted on the support rod 11 so that the drag generated by the vanes 121 receiving the wind not only interlocks the rotation of the impeller 12 but also the support rod 11 also swings. The higher the height of the support rod 11 is, the greater the swinging width becomes and the more likely it is to cause danger.
Furthermore, each blade 121 on the impeller 12 is deformed by the received lift, and there is a problem that power generation efficiency is lowered.
