Plan for the Wind Power Device to Make the Best of Earth Wind Energy

To make the best of wind energy resources on the earth surface, the plan for a new type of wind power device, named Multiple wind wheel Wind power Device, MWD in short, was put forward. MWD composes steel tower, trusses, generator, long axis, wind turbines and wheel boxes. Only one generator installed on the ground in the middle of the generator room vertically. Several wind turbines installed to the steel tower of MWD, each wind turbine consists of front wind wheel, back wind wheel and wheel box. Common yawing equipment used for the wind turbine at top of the steel tower. Installed with bearings to the steel tower of MWD, driven by a common yawing equipment, each truss can turn slowly and independently around the steel tower as the wind changes its direction. The mechanical power generated by the wind turbines at ends of the trusses is continuously transmitted to the central axis in the middle of the steel tower via a special transmission. It is for the special design of MWD that the wind energy in both the high air and low air can be utilized, the wind energy escaping from back of front wind wheel also utilized. It is known by calculation that MWD will produce electricity 3.9~6.4 times of that produced by present wind power device in commercial operation.
