Abstract
A turbine blade combined horizontal axis wind wheel taking natural wind as power can be arranged on a horizontal axis wind turbine such as a wind driven generator taking natural wind as power, a wind power water elevator and the like.
The utility model discloses mainly constitute by turbine, oar wing and wheel hub, turbine, oar wing are all installed on wheel hub. The method is characterized in that: the wind power generation system has the advantages of low starting wind speed, low operating wind speed reaching the rated rotating speed required by the load, high utilization rate of natural vortex wind and tight flow wind energy, and high adaptability in areas with low wind speed and complex terrain.
Description
The utility model relates to a kind of turbine slurry wing combined type horizontal axle wind mill wind wheel of doing power with natural wind.It is on the horizontal-shaft wind turbine such as wind-driven generator, wind power water pumping machine of power that this wind wheel can be installed in the natural wind.
Before the utility model proposes, the wind wheel of doing motivation level axle wind energy conversion system with natural wind mostly is slurry wing formula wind wheel greatly, this wind wheel is that the slurry wing is installed on the wheel hub, it is higher to there is starting wind velocity, reaches rated speed and requires shortcomings such as the capacity usage ratio of wind speed height, eddy current and turbulent wind is lower.
The purpose of this utility model is exactly a kind of turbine slurry wing combined type horizontal axle wind mill wind wheel that provides at the deficiency of above-mentioned slurry wing wind wheel.
The purpose of this utility model can realize by following measure, promptly adopt the combination of turbine, the slurry wing and wheel hub, its structure is that turbine plate [3] is installed on wheel hub [5] or the petiole [2], turbine blade [4] is installed on turbine plate [3] one side end faces, petiole [2] one ends are fixed on the wheel hub [5], and its other end connects the slurry wing [1].
The purpose of this utility model can also realize by following measure:
Turbine plate [3] is axially vertical and concentric with wheel hub [5].
Petiole [2] and wheel hub [5] axially have an angle α, and its numerical value is 60 °＜α＜90 °.
Backguy [6] between the wing tip of starching the wing [1] and wing root makes the slurry wing [1] archwise.
The utility model has following advantage than prior art:
1, starting wind velocity is low.
2, it is low to reach the running wind speed of load rating rotating speed.
3, turbine and turbulent wind capacity usage ratio are than higher.
4, more intense at low wind speed and regions with complex terrain adaptability.
The accompanying drawing drawing is described as follows:
Fig. 1 is a general assembly schematic representation of the present utility model, and wherein [1] starches the wing, [2] petiole, [3] turbine plate, [4] turbine blade, [5] wheel hub, [6] backguy.
Fig. 2 is a side view of the present utility model, wherein starches wing handle and axial clamp angular region and be 60 °＜α＜90 °.
Be described further as follows in conjunction with Fig. 1～2:
When this wind wheel during in state of rest, natural wind trend air-flow acts on the wind wheel surface, when its value is enough big, owing to be subjected to the screen shelves effect of turbine plate, make airflow concentration and affact and starch on the wing, this obtains torsion down in the air-flow effect turbine, its direction is opposite with turbine blade involute direction, simultaneously, slurry wing the place ahead natural wind also acts on the slurry wing and produces lift, its direction is identical with turbine torsion direction, and turbine torsion and the acting in conjunction of slurry wing lift make wind wheel obtain moment and start on the wind wheel wheel hub.
During the wind wheel running, the air-flow that acts on the turbine is subjected to the turbine blade centrifugal action, discharge along the radiation of turbine blade tangent direction, its speed is greater than natural wind, starching wing front with natural wind force action anchor ring, the place ahead air-flow and wind wheel rotation direction are rotated in the same way, apply running torque with joint efforts to the slurry wing continuously, simultaneously, turbine also produces continuous running torque, at this moment, when runner torque produces negative pressure in turbine the place ahead during less than slurry wing torque, force the place ahead air-flow to replenish, thereby form continuous swirling eddy, increased the effect air quantity of wind wheel to the turbine direction.
When turbine rotational speed is enough high, the force action anchor ring of turbine blade tangent direction air-flow and natural wind is displaced to slurry wing reverse side rear side, because air-flow resistance shelves and oppositely lift effect reduce the air-flow by wind wheel, the continuation of restriction wind speed round improves, and the unlikely hypervelocity of wind wheel is damaged.
