Background technology
With flourishing for China's Wind Power Generation Industry, the ability of Wind turbines is also more powerful.Wind-driven generator is in fortune
During turning, in order to obtain the wind speed or relatively stable wind speed of maximum, it is necessary to adjust the angle of wind turbine using yaw system
Degree.
Traditional yaw system is to gather the data such as wind direction, wind speed by horizontal yaw gear, enables Wind turbines root
According to demand timely adjustment direction in the horizontal direction, to obtain maximal wind-energy or most stable of wind energy.But the wind of reality is simultaneously
It is non-fully bottom horizontal flow sheet, it is also angled in vertical direction.
Traditional yaw system, has used many wind power plants, however as developing rapidly for wind-power electricity generation,
In order to build the intelligent grid of plug and play, the requirement more and more higher to wind-powered electricity generation quality.How to obtain more stable rotating speed and
Higher-quality wind-powered electricity generation, is aspect that many enterprises more pay attention to.
If can make Wind turbines in vertical direction also can adjustment angle, just can preferably catch required wind, make electricity
Machine rotating speed is more stable.It is made however as fan blade increasing, its weight will allow it can be vertical also being continuously increased
Side adjusts upward angle, and the intensity of ability and supporting construction to lifting structure has higher requirements.
The content of the invention
The technical problem to be solved in the present invention is how to facilitate, be achieved at low cost Wind turbines angle in vertical direction
Degree adjustment.
In order to solve the above-mentioned technical problem, the technical scheme is that to provide a kind of wind-driven generator of vertical direction inclined
Boat system, it is characterised in that：Including the vertical yaw detector for detecting the wind-force information in vertical direction, vertical driftage is passed
Sensor is connected with analytic operation unit, and analytic operation unit is connected with signal amplification unit, signal amplification unit and hydraulic lifting
Equipment is connected, and hydraulic lifting equipment is connected with vertical Yawing mechanism, and vertical Yawing mechanism connects wind-driven generator.
Preferably, vertical yaw detector detection wind speed, wind direction information in vertical direction, and will detect
Information is converted to electric signal and passes to analytic operation unit.
It is highly preferred that the analytic operation unit receives vertical yaw detector and is transmitted through next electric signal and is processed,
Analytical calculation goes out the angle that wind-driven generator should be adjusted in vertical direction, and angle signal then is converted into lifting signal transmission
To signal amplification unit.
Further, the signal amplification unit is amplified place to the lifting signal that analytic operation unit is passed over
Reason, and by the signal transmission after enhanced processing to hydraulic lifting equipment.
Further, after the hydraulic lifting equipment receives the signal that signal amplification unit is transmitted through, to vertical inclined
Plane structure provides the lift or pulling force of correspondence size.
Yet further, the lifting of the vertical Yawing mechanism causes that wind-driven generator is presented different angles in vertical direction
Degree.
Preferably, the hydraulic lifting equipment and vertical Yawing mechanism are located at the top of conventional flat yaw system, and
It is connected with conventional flat yaw system by nacelle chassis.
The wind driven generator yaw system of the vertical direction that the present invention is provided, compensate for traditional yaw system can only be in level
The defect being adjusted to blower fan angle on direction so that angle is also adjustable in vertical direction for wind-driven generator, is received to blower fan
The adjustment in wind face enters three dimensions from two dimensional surface, can more accurately catch wind energy.System architecture is simple, it is easy to look forward to
Industry is according to oneself requirement adjusting parameter, the wind energy needed for obtaining；Additionally, the system belongs to the type of installing additional, to existing tradition driftage
System is slightly adjusted can be just applied in combination, and save cost and time.
