Above-mentioned base intermediate portion is two cylindrical cavities that communicate up and down, and upper cylindrical cavity is greater than lower cylindrical cavity, and bearing is installed at upper cylindrical cavity top, and lower bearing is installed in upper cylindrical cavity bottom, and above-mentioned lifting cover is installed in upper bearing (metal) and the lower bearing.
Further be: axially offer a groove along the blower fan bar on the outside thread of above-mentioned blower fan bar, and at the end face of base one position limit pin is installed, this position limit pin one end is fixed on base top surface, one end gos deep into above-mentioned inside grooves, so can limit whole blower fan bar lifting when rotation cover not along with rotation.
Further be: a worm type of reduction gearing is installed on the above-mentioned drive motor, and the input shaft of worm type of reduction gearing connects the output shaft of drive motor, and the output shaft of worm type of reduction gearing is connected with above-mentioned small gear key.The self-locking property of this covering device so can be provided.
The invention has the beneficial effects as follows:
Base of wind driven generator of the present invention by the thread engagement transmission of lifting cover and blower fan bar, highly carries out self-protection so that wind-driven generator can reduce stably when running into severse weather.Thus, more lengthen the working life of a whole set of power generation system, and package unit is simple in structure, and transmission is stable, and is not fragile, can be easily with this floor installation in other wind powered generator system with the blower fan bar.

Embodiment
Below in conjunction with drawings and Examples the specific embodiment of the invention is described:
Fig. 1,2,3 shows the structure of one embodiment of the invention, and as shown in the figure, native system mainly comprises, wind-driven generator 1, blower fan bar 2, small gear 3, drive motor 4, base 5, gearwheel 6, lifting cover 7, upper bearing (metal) 8, lower bearing 9.Wherein, wind-driven generator 1 is traditional wind-driven generator with impeller, wind-driven generator 1 is installed on the blower fan bar 2, support by blower fan bar 2, blower fan bar 2 is cylindrical shape, blower fan bar 2 is installed on the base 5, and whole blower fan bar 2 and wind-driven generator 1 support by base 5, and base of wind driven generator of the present invention can be with blower fan bar 2 in base 5 interior liftings.
In order to realize the purpose of lifting, outside thread is offered in the lower end of above-mentioned blower fan bar 2, the length of outside thread 2 equates with the cavity height of base 5, suit lifting cover 7 on the outside thread of blower fan bar 2, lifting cover 7 is the cylindrical body of a hollow, lifting cover 7 is offered the internal thread that is meshed with the outside thread of blower fan bar 2,7 outsides fixed installation gearwheel 6 is overlapped in lifting, gearwheel 6 rotates and can drive 7 rotations of lifting cover, installation one small gear 3 with gearwheel 6 engagements, drive motor 4 is installed in small gear 3 belows, and the output shaft of drive motor 4 and small gear 3 are connected by key, and the below of drive motor 4 is fixedly mounted on the end face of base 5.
Above-mentioned base 5 intermediate portions are step hole, the whole cylindrical cavity that forms, upper cylindrical cavity is greater than lower cylindrical cavity, and bearing 8 is installed at upper cylindrical cavity top, upper cylindrical cavity bottom is that step part is installed lower bearing 9, and above-mentioned lifting cover 7 is installed in upper bearing (metal) 8 and the lower bearing 9.
Thus; need to reduce when highly carrying out self-protection when wind-driven generator present position wind-force is excessive, drive motor 3 starts, and drives lifting cover 7 by meshed transmission gear and rotates; after lifting cover 7 rotates; since the engagement of the outside thread of its internal thread and blower fan bar 2 belows, according to the transmission principle of feed screw nut, the 2 beginning elevating movements of blower fan bar; certainly; the motion of this moment for descending, final so that whole wind-driven generator reduces height, protected the safety of whole electricity generating device.
