S4, shank 40 is detached from and embraces the pin hole of piece 20 and rotor 50 and embraces piece 20 and a rotor 50 to unlock, driving part is to phase
Opposite direction rotation, drives an armful piece 20 to turn left, and restores to original state.
When can also be prepared step S0, initial installation before step S1, first controls driving part and drive the first engagement
Toothing turns right, and the first engagement toothing is moved to the right end of rack gear band 14；
Generally, the height of driving part and master gear 15, which is higher than, embraces piece 20, in this way, from the fixing end of rack gear band 14 to master
15 position of gear, rack gear band 14 and the spacing embraced between 20 outer surface of piece are increasing, are unfavorable for being driven, in view of the above problems,
The present invention is further arranged as follows.
Device in the present invention further comprises two position limited gears positioned at 15 two sides of master gear, is axially parallel to master
Gear 15, two position limited gears are all set between master gear 15 and the outer surface of cross wall 22, and the gear shaft of two position limited gears is solid
Due to mounting base 30；The upper surface of each limiting tooth wheel and rack band 14 is engaged, each position limited gear and 15 interlaced arrangement of master gear in
The two sides of rack gear band 14.It is succinct for description technique scheme, herein by two position limited gears be defined as the first position limited gear and
Second position limited gear.The left end for embracing piece 20 is fixed in the left end of gear band, and right end is penetrated from below the first position limited gear, so
It penetrates from the top of master gear 15, is finally pierced by below the second position limited gear afterwards, be finally fixed on the right end for embracing piece 20.
Meanwhile first position limited gear and the second position limited gear be also beneficial to tensioning rack gear band 14, be further conducive to rack gear
With 14 steady reliable transmission.
In the various embodiments described above, the quantity of motor perhaps motor can be at least two each motors or motor
Drive shaft is connected with the master gear 15, and each master gear 15 engages toothing engagement with second.The present invention gives drives
Dynamic component is the specific embodiment of three motors, and three motors are respectively defined as: first motor 11, the second motor 12 and third
Motor 13；Correspondingly, master gear 15 is also three, is respectively as follows: the first master gear 151, the second master gear 152 and third master gear
153.First position limited gear 71, the first master gear 151, the second master gear 152 and third master gear 153 and the second position limited gear 72
Interlaced arrangement is in the two sides of rack gear band 14.
The positioning region of mounting base 30 as described above can be pin shaft or pin hole, i.e. mounting base 30 is positioned at by pin shaft
On base 60.The specific embodiment that positioning region is pin hole is shown in figure, it is respectively the first pin hole 31 that pin hole, which is specially two,
With the second pin hole 32.It is commonly installed seat 30 to be positioned on base 60 by the two groups of pin shafts in left and right, each group can be one, can also
Think two or more, there is shown herein the embodiments that one group includes a pin shaft or pin hole, i.e., at left and right sides of vertical plate
A pin shaft is respectively set, it is in running order in order to make moment of torsion suffered by two pin shafts etc. as far as possible when rotor 50 rotates
Each motor or the whole longitudinal center plane preferably with respect to two pin shafts that constitutes of motor be arranged symmetrically.
In the various embodiments described above, mounting base can specifically include vertical plate, and driving part is supported in the upper end platform of vertical plate, stand
The lower end of plate has the arcuate structure being coupled with the outer profile of base 60.
It being confirmed by a large number of experiments, during rotation, load can accordingly change rotor 50, for counterclockwise,
As rotational angle increases, bending load is gradually reduced, and load change trend can refer to Fig. 6, and wherein abscissa indicates rotation
Angle, ordinate indicate moment of flexure.When rotor 50 0 ° to 40 ° of interval ranges when, moment of flexure needed for rotating rotor 50 is maximum；When turn
When son 50 turns to 40 ° to 60 ° of interval ranges, moment of flexure needed for rotating rotor 50 is opposite to be reduced；When rotor 50 turns to 60 ° extremely
When 120 ° of interval ranges, moment of flexure needed for rotating rotor 50 is minimum.
For the above discovery, following improvement further has been carried out to device herein.
The device for rotary wind power generator rotor in the present invention further comprises detection part 80 and controller.Inspection

By taking above-mentioned driving part is three as an example, when controller judges that the rotational angle of current state rotor 50 is located at 0 ° extremely
When 40 ° of ranges, it can control three driving parts (motor or motor) and work at the same time, to drive rotor 50 to rotate jointly；I.e.
First motor 11, the second motor 12 and third motor 13 work at the same time；
When controller judges that the rotational angle of current state rotor 50 is located at 40 ° to 60 ° of ranges, it can control two drives
Dynamic component works at the same time, to drive rotor 50 to rotate jointly；Take into account symmetric design principle described above, preferably first motor 11
It is worked at the same time with third motor 13；
When the rotational angle of controller current state rotor 50 is located at 40 ° to 60 ° of ranges, a driving portion can control
Part work, to drive rotor 50 to rotate.The second intermediate motor 12 is preferably placed to work independently.
Correspondingly, the above-mentioned control method of the present invention can also increase step S12 and step S13 before step S2, specifically
Are as follows:
The rotational angle of S12, real-time detection current state rotor 50；
S13, the number according to the driving part of the rotational angle control work at present of the current state rotor 50 of detection
Amount.
In transmission process, embraces piece 20 and be possible to relatively close to mounting base 30, it, can be in order to avoid the two contact wear
Idler wheel 100 is set on embracing two opposite surface one of them of both piece 20 and mounting base 30, the quantity of idler wheel 100 can be more
It is a, it is preferably disposed in mounting base 30.In this way, the two can pass through idler wheel even if embracing piece 20 to when the relative movement of mounting base 30
100 are in rolling contact, and avoid phenomena such as interfering.
In order to improve lifting efficiency, mounting base 30 is additionally provided with locking pin 33, and piece 20 is embraced in the releasable connection of locking pin 33
