The utility model is through the control to empennage; The rotor blade overspeed rotation that can effectively evade the forward large wind and cause; Can let rotor blade and wind-force keep an appropriate angle all the time; Both can make rotor blade receive that bigger wind-force promotes, can avoid the overspeed rotation that causes owing to the forward large wind again, cause the damage of power generating equipment then.
Description of drawings
The wind-driven generator structure schematic representation that Fig. 1 provides for the utility model.
Fig. 2 is wind-driven generator empennage and empennage yaw motor partial structurtes schematic representation.
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
This wind-driven generator comprises cabin 1, empennage 3, is arranged on the rotor blade 2 and the empennage crosswind Yawing mechanism 4 of cabin head, and empennage 3 is rotationally connected with cabin 1 afterbody, empennage crosswind Yawing mechanism 4 empennage 3 that is in transmission connection.Empennage crosswind Yawing mechanism 4 comprises bearing plate 41, motor 42 and a Transmitted chains 43, and motor 41, Transmitted chains 43 are connected on the bearing plate.Transmitted chains 43 is the driving gear 431 and driven gear 432 of a pair of transmission that is meshing with each other, and driving gear 431 is connected on the motor shaft, and driven gear 432 is connected in the rotating shaft of empennage 3.Transmitted chains 43 also can adopt driving belt, and corresponding driving gear 431 is replaced by a pair of belt pulley that is in transmission connection with 432 of driven gears.
One side of driven gear 432 is provided with touches pin 15; Be provided with first limit switch 12, second limit switch 13 respectively corresponding to touching two limit positions place that pin 15 rotates on the driven gear 432 on the bearing plate 41, this touches pin 15 and touches respectively and connect first, second limit switch.Perhaps also can the side that first limit switch 12, second limit switch 13 are arranged on driven gear 432 be separated by certain rotation angle two with on the path length position; On the bearing plate corresponding to driven gear 432 on the position of two limit switches be provided with and touch pin 15, and touch pin 15 and touch respectively and connect first, second limit switch.
Driven gear 432 is provided with inductive displacement transducer 14 or metal detection bar 16, on the position of bearing plate 41 correspondences and inductive displacement transducer 14 or metal detection bar 16, is provided with metal detection bar 16 or inductive displacement transducer 14.
Under original state, touch pin 15 and contact during work with the switch reed of first limit switch 12.As under the not too big situation of wind-force; Can make empennage 3 be in the center position in cabin 1; Empennage 3 makes that under the effect of wind-force the rotor blade 2 of cabin 1 head is relative with the direction forward of the wind comes from, and rotor blade 2 obtains the maximum rotation moments at this moment, and wind-driven generator generates electricity with peak output.If wind speed is excessive, the then rotation through control motor 42 drives driven gears 42 by driving gear 41 again and makes empennage 3 deflections; Metal detection bar 16 deflection thereupon; And make generation empennage 3 deflection angle signals in the inductive displacement transducer 14, after deflecting into the angle of setting, motor 42 stops operating; Make empennage 3 depart from the center position in cabin 1, produce the deflection of several angle.Like this, cabin 1 under the effect of empennage 3 with the direction several angle that staggers of the wind comes from, rotor blade 2 rotating speeds are slowed down, remain on a suitable scope, thereby protected the not too fast rotor blade speed of reason and being damaged of the relevant device in the wind-driven generator.If empennage 3 overswings, touching pin 15 can offset with the reed of second limit switch 13, makes correspondent control circuits stop the rotation of motor 42, prevents that empennage 3 and cabin 1 from bumping.
The utility model is through the control to empennage; The rotor blade overspeed rotation that can effectively evade the forward large wind and cause; Can let rotor blade and wind-force keep an appropriate angle all the time; Both can make rotor blade receive that bigger wind-force promotes, can avoid the overspeed rotation that causes owing to the forward large wind again, cause the damage of power generating equipment then.
