<P>PROBLEM TO BE SOLVED: To solve the problem wherein natural energy is more actively used over the world to prevent global warming, wind power energy among the natural energy attracts attention of people together with solar energy and the number of installation thereof has been drastically increasing, and in the case of using wind power energy for pump-up operation of a pump, if the pump is driven by a general wind mill through a generator, an accumulator and a motor, effective energy is reduced in multiplication of efficiency of each equipment, and the energy to be actually used to drive the pump is reduced. <P>SOLUTION: A main spindle of the pump is connected to a main spindle of an impeller of the wind mill without converting wind power energy to electric energy, and an energy loss on the way is reduced by mechanically directly driving the pump to use wind power energy to the maximum as the energy for driving the pump. <P>COPYRIGHT: (C)2011,JPO&INPIT |
