Description
Technical field
The utility model relates to a kind of wind wheel arrangements for speed regulation of wind power generating set, particularly a kind of wind turbine automatic yaw speed-regulation arrangement.
Background technique
Wind-driven generator is by wind energy power, but when wind speed suddenlys change, huge wind energy changes will pass to parts such as main shaft, generator by wind energy conversion system, produce very big mechanical stress on these parts.If the direction of facining the wind of uncomfortable completeblade will cause because of wind speed is excessive pylon to be collapsed or motor such as burns out at problem.Thereby wind-driven generator in the market mainly takes two kinds of methods to regulate the big wind speed of tower body adaptation.The one, by the mode of facining the wind of adjustment blade, the 2nd, utilize solid of rotation to adjust the direction of whole fan blade.These two kinds of methods all are to utilize motor and automatically controlled control, there are a lot of hidden danger in the wind wheel arrangements for speed regulation of these two kinds of conventional methods: when adopting Electric Machine Control, when wind speed strengthens suddenly, motor can burn a large amount of electronic original parts, sensor, gear ring, Hydraulic Power Transmission System because of bearing, cause this control system rate of fault height, complex structure, cost height, operating difficulties, control system is easily malfunctioning etc. during high wind.
Summary of the invention
The purpose of this utility model is to provide a kind of wind power generating set that is applicable to all size, is specially adapted to the large-scale wind turbine automatic yaw speed-regulation arrangement that the above unit of MW class of tail type is arranged.
The utility model is achieved through the following technical solutions:
A kind of wind turbine automatic yaw speed-regulation arrangement of the present utility model, comprise that the wind-driven generator tower frame upper support has fuselage, the front end of fuselage is provided with blade of wind-driven generator, wherein: directly over afterbody, be provided with a forward wind wheel that changes to a lateral deviation by the fan blade of forward wind wheel they sup-port, at the opposite side of the forward wind wheel deflection of afterbody, fuselage side substantially horizontal is provided with a side direction wind wheel by side direction wind wheel they sup-port.
Wind turbine automatic yaw speed-regulation arrangement described in the utility model, wherein: the rotating shaft axis of described forward wind wheel and fuselage axis angle in the horizontal direction are+30 °, are 90 ° at the angle of Vertical direction.
Wind turbine automatic yaw speed-regulation arrangement described in the utility model, wherein: described side direction wind wheel rotating shaft axis and fuselage axis angle in the horizontal direction are-30 °, are 5 ° at the angle of Vertical direction.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further, but not as to qualification of the present utility model.
As shown in Figure 1, a kind of wind turbine automatic yaw speed-regulation arrangement, comprise that wind-driven generator tower frame 8 upper supports have fuselage 1, the front end of fuselage 1 is provided with blade of wind-driven generator 7, wherein: directly over afterbody, be provided with the forward wind wheel 2 that a fan blade that is supported by forward wind wheel strut 6 changes to a lateral deviation, opposite side in forward wind wheel 2 deflections of afterbody, fuselage 1 side substantially horizontal is provided with a side direction wind wheel 3 that is supported by side direction wind wheel strut 5, as shown in Figures 2 and 3, be that expression a kind of wind turbine automatic yaw speed-regulation arrangement tail structure enlarged diagram of the present utility model and partial structurtes A are to schematic representation.In Fig. 3, the rotating shaft axis of described forward wind wheel 2 and fuselage 1 axis angle in the horizontal direction are+30 °, are 90 ° at the angle of Vertical direction, as shown in Figure 2.In Fig. 2 and Fig. 3, described side direction wind wheel 3 rotating shaft axis and fuselage axis angle in the horizontal direction are-30 °, are 5 ° at the angle of Vertical direction.Described side direction wind wheel strut 5 hinge types are movably connected in fuselage 1 rear end one side, and its side direction wind wheel strut 5 is 5 ° with the Vertical direction angle of fuselage center line.
Working principle
During proper functioning, forward wind wheel 2, side direction wind wheel 3 play the effect of adjusting the main frame wind wheel, make the main frame wind wheel down with the wind positive all the time.When surpassing rated wind speed, forward wind wheel 2 is because of diameter is little, so the angular velocity height, thereby presents " gyroscope " phenomenon, promotes forward wind wheel 2 positive facining the wind because inertia strengthens the length (moment * arm of force) of empennage; Simultaneously, during change of the wind, side direction wind wheel 3 wind-engagings, identical with the working principle of forward wind wheel 2, side direction wind wheel 3 positive facining the wind are because of forward wind wheel 2, side direction wind wheel 3 have certain included angle with the main frame wind wheel, when forward wind wheel 2, when the 3 positive pressures of side direction wind wheel are facingd the wind, the main frame wind wheel will depart from wind direction, and form certain angle with wind, thereby reach the purpose of driftage.Because of side direction wind wheel 3 is that movable hinge connects, can be provided with the wind, its rotating speed can be 0.
