Preferably under wind-force effect, the sense of rotation of front fan and aft-fan is contrary, makes wind generating unit be subject to rotating torques partial offset or the balance being produced by described fan as a kind of, and wind generating unit can obtain good stressed.
As a kind of preferred, the lobe numbers of front fan and aft-fan is 3.
As a kind of preferred, the individual blade shape of front fan individual blade shape and aft-fan is compared, and described blade shape is symmetrical about vertical plane.
As a kind of preferred, described bearing is deep groove ball bearing or roller bearing.
As a kind of preferred, described axle is connected to planetary pinion sun gear, and described hollow shaft is connected to planetary pinion gear ring, and a plurality of planet wheels have common planet carrier, and planet carrier is exported rotating power.
As a kind of preferred, this device is arranged on wind tower or top of building.
As a kind of preferred, a kind of wind tower, comprises described wind generating unit.
As a kind of preferred, a kind of building, comprises described wind generating unit.
Useful technique effect: 1, can make full use of wind energy on same wind generating unit, improve generating efficiency; 2, contrary by the sense of rotation of fan, can countertorque reduce or balance, improve the life-span of wind force device parts, reduce costs; 3, be applicable to being very much arranged on wind tower or top of building, make full use of the wind energy of wind tower or top of building.
Accompanying drawing explanation
Fig. 1 is the blade schematic diagram in wind generating unit fan front;
Fig. 2 is the wind generating unit front end generalized section corresponding to Fig. 1;
Embodiment
As illustrated in fig. 1 and 2, front fan 1 has center hole, and internal spline or keyway are set in hole, and aft-fan 2 has center hole, and internal spline or keyway are set in hole, and front fan 1 and aft-fan 2 front and back are coaxially arranged, and front fan 1 is front, and aft-fan 2 is rear.The blade shape of front fan 1 and aft-fan 2 adopts blade shape of the prior art, and lobe numbers can be for a plurality of, as a kind of preferred, the lobe numbers of front fan 1 is 3, the lobe numbers of aft-fan 2 is 3, and the lobe numbers of front fan 1 and aft-fan 2 can be identical, also can be different.
