Description:
BACKGROUND OF THE INVENTION 
       [0001]    This invention relates to a wind turbine. A wind turbine is a device for converting the energy of wind into mechanical rotary energy through the medium of a propeller type windwheel possessed of a plurality of rotor blades and further converting this mechanical rotary energy into electric energy by, for example, an electric generator. The operating condition of the wind turbine varies with the velocity of the wind. Specifically, the revolution number and torque of the windwheel increase and the loads such as the force of air and the centrifugal force which are exerted on the rotor blades are also increased in proportion as the velocity of wind increases. To fix the revolution number of the rotor blades, the motion of the blades is controlled by means of a variable pitch mechanism, for example. This control mechanism, however, fails to provide the expected control when the blades are exposed to a wind of unusually high velocity such as those encountered during a typhoon. Under the great pressure of the wind, the rotor blades and the rotation system of the motor may, in an extreme case, even break. The wind turbine, therefore, has an evident need of being provided with a safety measure to preclude breakage whilst still generating electrical energy. 
         [0002]    The rotor blades in the majority of the existing windwheels are made of glass fiber, aluminium and wood. They must be given maintenance and inspection at fixed intervals of once at least every several months. At times, they must be replaced. In some of the existing wind turbines, the propeller type windwheels are installed on towers which stand 40 to 90 meters from the ground level. The replacement of rotor blades and the maintenance and inspection given to the interior of the nacelle, accordingly, have entailed extremely dangerous work at great heights. 
         [0003]    As one kind of the safety measure of the type mentioned above, we propose a method by which the turbine nacelle and windwheel is lowered automatically to reduce stresses on the tower and on the windwheel blades whenever high winds are encountered. Wind speeds increase the higher above ground you are, conversantly, they reduce the closer you are to the ground. By reducing the height of the nacelle and blades, lower winds will likely be experienced. 
         [0004]    A major concern of wind turbine owners is the number of kilowatt hours of electrical energy produced by a wind turbine. Historically, in high winds, turbines require shut-down, however, peak wind conditions are also peak power generating conditions. We propose that instead of shutting down a wind turbine during its peak operating environment, the wind turbine operating conditions should be altered to take advantage of these environmental factors, whilst reducing possible damage to the wind turbine system. In the event of catastrophic winds, the nacelle and blades would be lowered to the ground and operation stopped. 
         [0005]    Using a system whereby the nacelle and blades are able to be lowered to ground level means maintenance work can be conducted rapidly and efficiently, whilst removing the need for working at dangerous heights. This methodology also removes the requirement for large cranes to be brought on-site to manage routine maintenance.
