     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The detail content of the invention is described below along with accompanying Figs.: 
     A preferred embodiment of the invented high efficient compounded wind power system as shown in  FIG. 1  comprises: a base  3  is installed with a wind power unit  1  thereon and a compound unit  2  to mutually drive and transfer power with said wind power unit  1 , thereby to obtain a better efficient wind power generation output. 
     As shown in  FIGS. 2 to 7 , said wind power unit  1  includes a wind hood  11 , a plurality of fan blades  12  installed externally to said wind hood  11 , a wind power unit driving main transmission shaft  13  installed behind said wind hood  11 , and a wind power unit driving gear  14  installed said main transmission shaft  13  to form a separation with said wind hood  11 . 
     Said compound unit  2  is installed on said wind power unit driving main transmission shaft  13  and is located behind said wind hood  11 , wherein it comprises: a gravity wheel  21 , a plurality of gravity shaft arms  22  installed externally to said gravity wheel  21 , and a plurality of swingable gravity wheels  23  which are connected respectively with each gravity shaft arm  22  at the end whereof. 
     A sleeve area  15  for inserting said gravity wheel  21  is formed on said wind power unit driving main transmission shaft  13  in the vicinity behind said wind hood  11  thereof. 
     Said fan blades  12  are blown by wind to rotate thereby to produce a main power output  16  and an auxiliary power output  17 , wherein said main power output  16  is transmitted to wind power unit driving main transmission shaft  13 , whereby said main power output  16  is continuously transmitted by said wind power unit driving main transmission shaft  13  to drive the generator  4 . 
     Said auxiliary power output  17  is transmitted to said compound unit  2 , whereby gravity wheel  21  and gravity shaft arms  22  of said compound unit  2  are rotated synchronously, and each gravity wheel  23  installed at the end of each gravity shaft arm  22  are also swung synchronously. 
     When said gravity wheels  23  are swung synchronously, another main power output  18  similar to above said main power output  16  is generated synchronously, and another main power output  24  is further used to drive above said generator  4 . 
     When said gravity wheels  23  are swung synchronously, above said auxiliary power output  17  is continuously transmitted to wind power unit  1  to make the plurality of fan blades  12  rotated continuously. 
     Said gravity wheels  23  appear in different angles during swinging process and is moving up and down at a fixed height. So called “High Efficient Wind Power” is produced by the high efficient compounded wind power system, wherein said high efficient compounded wind power system is to additionally attach one compound unit  2  on the existing wind power generation equipment (i.e. wind power unit  1 ), thereby to form mutual driving and mutual power transmission between the said two units so as to achieve an eternal and continuous operation with better energy economic effectiveness. 
     In essence, when said fan blades  12  is blown by the wind to rotate, a main power output  16  and an auxiliary power output  17  are produced, in case of small wind or no wind, the fan blades  12  are unable to rotate, at the moment, the auxiliary power output  17  is fed back by the installed compound unit  2  to fan blades  12  and drives said wind power unit  1  to rotate, thereby the present wind power generation equipment will not be annoyed by stopping rotation in the future, and the existing energy consuming problems such as friction forces, air resistances and gravity, etc. in the compound unit  2  can be completely overcome. 
     Said compound unit  2  is driven by said wind power unit  1 , wherein said compound unit  2  is through rotation of said gravity shaft arms  22  as well as swinging and up and down movements of gravity wheels  23  to produce potential energy, gravity acceleration and inertia, whereby the potential energy is converted to mechanical power which is further converted to kinetic energy or electric power. 
     Therefore, by utilizing the interactive power transmission and feedback operating status of the “high efficient wind power” characterized high efficient compounded wind power system, though operation of wind power unit  1  has to rely on the wind to push said fan blades  12  for initial operation, it is automatically operated afterwards, wherein even in no wind, light wind or low wind conditions, the present imperfections for present wind power generation equipments being unable to generate power at such said conditions can be improved to allow said fan blades  12  to operate at 24 hour-days incessantly, thereby the operating effectiveness of present wind power generation equipment can be sufficiently promoted to maintain highly stable energy output, and in case of component failure, it can be replaced or repaired and the said operation can be continued again. 
     As summarized from above descriptions, the invention has the characteristics of all day long continuous operation, operating effectiveness promotion for present wind power generating equipments and a highly stable energy production, etc. in comparing with present structure of wind power generation equipments, therefore it is a relatively good invention meeting the requirement for new type patent application which is applied for approval herein according to the law. 
     The invention is described in detail using above said preferred embodiments, however the above said ones are only purposed to let those skilled of the arts to understand the invention, and is not intended to limit the application range of the invention. Therefore, all equivalent changes or modifications referring to said characteristics and spirits in forms and structures claimed by the invention shall be include in the scope of claims in the invention.
