Can be a kind of inexhaustible regenerative resource, with technology maturation, advantage of lower cost, have fewer environmental impacts
Etc. advantage.Wind Power Utilization mainly has two ways：One kind is to convert wind energy into mechanical energy using wind power generation plant to convert again
Be electric energy, i.e. wind-power electricity generation, it is relatively early that this Wind Power Utilization mode is studied, formd maturation wind-powered electricity generation is theoretical and industry
Pattern, but this wind-power electricity generation needs complicated control system, in addition it is also necessary to expensive mating electrical equipment, limit its hair
Exhibition；Wind energy is converted into mechanical energy by another kind using mechanical device, such as utilizes wind-driven water pump.Water pumping of the wind-force is used as having
Effect utilizes wind energy, solves the problems, such as the important form of agricultural irrigation, is a kind of simple, reliability, practicality, efficient application technology.Its
Mechanical structure is uncomplicated, with low cost, manipulate and easy to maintenance, and the requirement of number is not very during to annual mean wind speed and effective wind speed
It is high.But water pumping of the wind-force also there are problems that many insoluble, such as increase blade wind energy utilization, raising power output and ask
Topic, need further research.
In order to reduce the threshold wind velocity of wind-driven water pump, usually increase the number of blade, causing the number of blade more rotor solidity compared with
Greatly, so as to influence its wind energy utilization.In order to lift the wind energy utilization of wind-driven water pump blade, solved there has been proposed a lot
Method：Chinese patent application 201510434944.4 discloses a kind of " pneumatic equipment bladess that blade tip trailing edge is serrated ", it
Slot blade tip trailing edge part so that blade tip trailing edge is serrated, and to reduce noise, but can not improve blade output performance, and work
Skill is complicated；Chinese patent application 201520412592.8 discloses a kind of " blade of vertical axis wind turbine with flow guide bar ", it
Open up to a flow guide bar is respectively installed at 20%, 40%, 60%, 80% to lift wind factor along blade, but this can only with hang down
D-axis wind energy conversion system, using narrow and relatively costly；Chinese patent application 200410017010.4 discloses a kind of small with blade tip
The horizontal-shaft wind turbine of the wing, improves the efficiency of wind energy conversion system by installing winglet at Axis Wind Turbine With A Tip Vane, but document winglet by
In aerofoil profile is used, so structure is more compared with complicated, operation, cost of manufacture is high, installation difficulty；Chinese patent application
200820055227.6 disclose a kind of horizontal-shaft wind turbine with tip vane, and plate tooth is simply installed at blade tip
Shape winglet improves the combination property of wind energy conversion system, and the small wing-like of the method optimization can adjust stall, but can not effectively improve
The power output of blower fan.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of to provide a kind of for wind-driven water pump existing for prior art
The wind wheel with gurney flap blade, the utility model can effectively improve the wind energy utilization with gurney flap blade wind wheel,
Increase the power output of wind-driven water pump wind wheel, overcome the shortcomings of existing traditional blades wind wheel.
According to the utility model proposes a kind of wind wheel with gurney flap blade for wind-driven water pump, its feature exists
In being included at trailing edge and be provided with blade body, outer ring wheel rim, inner ring wheel rim, wheel rim fix bar and the wheel hub of gurney flap, institute
State the quantity of the blade body that gurney flap is provided with trailing edge for 12, divide equally be arranged on inner ring wheel rim and outer ring wheel rim it
Between, phase difference be 30 degree, wheel hub is connected by wheel rim fix bar with inner ring wheel rim and outer ring wheel rim.
Realization principle of the present utility model is：On the one hand, the utility model at the trailing edge of blade body by setting lattice
Buddhist nun's wing flap, increased the curvature of aerofoil profile trailing edge, so as to increase effective camber of aerofoil profile, increased typical circular rector, and then increase
The lift of aerofoil profile；On the other hand, after the utility model is by setting gurney flap at the trailing edge of blade body, in lattice Buddhist nun
Wing flap rear generates the Karman vortex street that an alternating comes off, and the vortex street that the alternating comes off has induction to aerofoil profile upper surface air-flow
Effect, not only the air of suction surface is flowed through by, without separating, speed increases on the contrary, promotes aerofoil profile upper surface after gurney flap
The air-flow of trailing edge is adsorbed downwards, increased the energy of aerofoil profile upper surface flowing, makes it be more easy to resist adverse pressure gradient, is reduced in aerofoil profile
The area of surface Disengagement zone, makes stall, increases the stalling angle of aerofoil profile, so as to improve lift force coefficient, increased the wing
The lift-drag ratio of type, increases the power output of wind wheel.
Its remarkable advantage is the utility model compared with prior art：
One be the utility model proposes the wind wheel with gurney flap blade do not reducing blade and do not influenceing water pumping of the wind-force
On the premise of machine starting wind velocity, the wind energy utilization of blade is improve, wind-driven water pump wind wheel power output is increased, in wind speed
In the range of 4-10m/s, the power output of wind wheel averagely increases 2.71% than conventional wind water elevator wind wheel, and maximum increases
3.17%.
Two be the utility model proposes the wind wheel with gurney flap blade structure design it is entirely different with prior art,
See below table 3；The utility model proposes the wind wheel with gurney flap blade it is simple and reliable for structure, technique is easily manufactured,
It is easy to integrated design, is suitable for large-scale production.
