Further, above-mentioned mode of execution can also be modified into, directly drive actuation gear 11 with drive unit, drive direct actuation gear 11 with drive unit, make back shaft 1 must not rotate, can realize blade 22 foldings, because wind-driven generator is generally highly bigger, back shaft 1 is all longer usually, drives back shaft 1 rotation and can consume the more energy, extra drive unit is set drives actuation gear 11 and can save the energy and avoid back shaft 1 to produce wearing and tearing because of rotation simultaneously.Can also increase control gear and induction installation; control gear is connected with drive unit; induction installation is connected with control gear; transmit signal to control gear behind the induction installation induction wind speed; control gear makes the present invention can improve Wind Power Utilization efficient and effectively protects wind wheel 2 simultaneously according to the folding angle of current wind speed CCE adjustment blade 22.
Further, on the driven gear 23 positioning pin hole 231 can be set, the location pin 24 with positioning pin hole coupling 231 can be set on the supporting part 21, also comprise expansion device, expansion device with locate pin 24 and be connected, expansion device is connected with control gear.Expansion device control location pin 24 stretches out or withdraws, in the positioning pin hole 231 when location pin 24 stretches out on the insertion driven gear 23, driven gear 23 can't be rotated, and then locking blade 22 is to realize the function of location, moving gear 23 unlocks blade 22 is rotated during location pin 24 withdrawal, by the action of control gear control expansion device make blade 22 locking with unlock and can long-rangely realize.Positioning pin hole 231 can be provided with a plurality of, and it is that the circular of the center of circle is distributed on the driven gear 23 that a plurality of positioning pin holes 231 are with 23 cores of driven gear 230.A plurality of positioning pin holes 231 that circular distribution is set make blade 22 can be the multiple angles location, location pin 24 also can be provided with a plurality of, a plurality of location pin 24 can make stressed uniform distribution when blade 22 location, prolong the working life of single location pin 24.Location pin 24 is cylindrical, in the positioning pin hole 231 on the cylindrical insertion driven gear 23, the longitudinal cross-section of location pin 24 can be made into trapezoidal, perhaps the part of cylindrical insertion positioning pin hole 231 is made hemisphere, can make things convenient for positioning pin hole 231 and location pin 24 contrapositions like this, the situation that can't stretch into positioning pin hole 231 with location pin 24 under the situation of avoiding driven gear 23 and actuation gear long appearance skew 11 service times takes place.
Further, wind wheel 2 can be provided with a plurality of, a plurality of wind wheel 2 is concentric, a plurality of wind wheel 2 sense of rotation are parallel to each other, a plurality of wind wheels 2 rotate with unequal angular velocity, the blade 22 that a plurality of wind wheels 2 are set is each wind wheel 2 needn't be long, can reduce the difficulty of processing of blade 22, improves the intensity of blade 22 simultaneously.On this basis, a plurality of wind wheels 2 in Vertical direction be close to mutually and supporting part 21 size of each wind wheel 2 identical, blade 22 numbers of a plurality of wind wheels 2 are different, the blade of wherein superposed wind wheel 2 can be less than the blade of the wind wheel 2 that is positioned at the bottom, the present invention can following form implement on the basis of the above, blade 22 numbers that are positioned at the wind wheel 2 of the topmost part are 2, down blade 22 numbers of each wind wheel 2 increase by 1 successively, wind wheel can be provided with 5-7, the cylindrical body of blade 22 has played supporting effect to a pair of supporting part 21 of wind wheel 2, the cylindrical body of the blade 22 of each wind wheel 2 plays a supportive role to the supporting part 21 of adjacent wind wheel 2 again, whole wind wheel system structure is strengthened, the blade 22 of wind wheel 2 that is in rotating shaft 1 below simultaneously is more than the wind wheel 2 that is in rotating shaft 1 top, owing to all surround the identical cylindrical body of diameter after the blade 22 of each wind wheel 2 closes up, turning radius after making the blade 22 of wind wheel 2 of blade more than 22 open is less than the few wind wheel 2 of blade 22, and then make the big up and small down form of whole wind wheel system, because liftoff high more wind-force is big more, up big and down small wind wheel system can more effectively utilize wind energy, because overhead the turning radius of near more wind wheel is more little, make the soil of close wind-driven generator can obtain within a certain height utilizing simultaneously; On this basis, because the blade 22 number differences that each wind wheel 2 is comprised, make the natural frequency difference of each wind wheel 2, the harmonic component phase mutual interference that each wind wheel 2 rotation produced when a plurality of wind wheels 2 rotated, the frequency that makes each wind wheel 2 produce resonance changes, simultaneously, because the blade 22 number differences that each wind wheel 2 is comprised, make the air-flow phase mutual interference that the wind wheel blade 22 of a plurality of wind wheels 2 different wind wheel 2 when rotating with same angular velocity produces, thereby hindered the generation of pneumatic exciting.Though the vertical axis aerogenerator that above-mentioned mode of execution is made a little less than the honeycomb plate of single wind wheel structure on wind energy utilization but can prolong life-span of wind turbines rotor, reduce and heavyly makes the energy that wind turbines rotor consumes because of duplicating.
Further, also comprise generator, generator places the bottom of back shaft 1, and generator is connected with wind wheel 2 by driving mechanism.Generator can be placed ground, or even underground, be connected with wind wheel 2 by transmission device, generator position is reduced the maintenance and the maintenance that can make things convenient for generator, be not suitable for being designed to the occasion of external rotor type wind-driven generator under this mode of execution.
The above is only for preferred embodiment of the present invention, is not so limits claim of the present invention, so the equivalent structure that all utilizations specification of the present invention and diagramatic content have been done changes, all is included in protection scope of the present invention.
