Embodiment two
Fig. 3 is the structural schematic diagram of Double-wind wheel wind power generator provided in this embodiment, and Fig. 4 is leaf provided in this embodiment
The schematic diagram of wheel speed merging mechanism.The scheme of Double-wind wheel wind power generator provided in this embodiment greatly improves wind energy benefit
The increase that arrester quantity is also resulted in the increase of rate, but impeller quantity, improves the cost of lightning test.The present embodiment is logical
It crosses and tests unmanned plane with the use of the thunder and lightning in embodiment one, greatly reduce the quantity of arrester, reduce double wind wheel wind-force
The lightning test cost of generator.
Currently, improving the common method of the generated output of wind-driven generator, usually increase impeller diameter, to increase leaf
The front face area of wheel improves impeller-driven power, to improve generated output.But after impeller diameter increases, in order to ensure blower
Safety, wheel speed is usually smaller, and within 25 revs/min, air-flow is easy to pass through between adjacent blade, causes
Wind energy waste.
In order to efficiently use wind energy, generated output is improved, while reducing lightning test cost, present embodiments provided following
Wind-driven generator, comprising: one stage impeller 1, sencond stage impeller 2 and wheel speed merge mechanism；The wheel speed merges mechanism tool
There are the first input shaft 31, the second input shaft 32, the first output shaft 41 and the second output shaft 42, the one stage impeller 1 and described the
One input shaft 31 is drivingly connected, and the sencond stage impeller 2 is drivingly connected with second input shaft 32, and first output shaft 41 is logical
The input shaft for crossing first clutch and the first generator is drivingly connected, second output shaft 42 by second clutch with it is described
The input shaft of second generator is drivingly connected.
The one stage impeller 1 and the sencond stage impeller 2 are coaxially connected, and the length of blade of the one stage impeller 1 is greater than described
The length of blade of sencond stage impeller 2, and before direction of rotation when working is on the contrary, the one stage impeller 1 is located at the sencond stage impeller 2
Side.
When work, air-flow first passes through one stage impeller 1, then by sencond stage impeller 2, the diameter of sencond stage impeller 2 is less than level-one leaf
Wheel 1, therefore, sencond stage impeller 2 works required minimum wind speed again smaller than one stage impeller 1.In order to increase stabilization when head work
Property, the rotation direction of one stage impeller 1 and sencond stage impeller 2 is on the contrary, to offset torque.
Wherein, wheel speed merges mechanism and can merge the revolving speed of one stage impeller 1 and sencond stage impeller 2, to obtain more
Big output revolving speed, driven generator work improve generating efficiency to efficiently use remaining wind energy.
The wheel speed merges sun gear 51, gear ring 52 and the planet carrier 53 that mechanism includes coaxial arrangement, the planet
Frame 53 is equipped with multiple planetary gears 54, and the gear ring 52 is equipped with internal tooth and external tooth, and the planetary gear 54 is engaged on the gear ring 52
Internal tooth and the sun gear 51 between, first input shaft 31 be equipped with driving gear 55, the driving gear 55 with it is described
The outer tooth engagement of gear ring 52, second input shaft 32 are connect with the shaft of the sun gear 51, the shaft of the planet carrier 53
It is drivingly connected by jackshaft 6 and output shaft, one end of the output shaft forms first output shaft 41, and the other end forms institute
State the second output shaft 42.
For example, the revolving speed of sun gear 51 is n1, the revolving speed of gear ring 52 is n2, and the revolving speed of planet carrier 53 is n3, in gear ring 52
The number of teeth ratio of tooth and sun gear 51 is a, n3=(n1+a*n2)/(1+a).To realize the superposition of revolving speed and torque.
In one example, the length of blade 75m of one stage impeller, the length of blade 35m of sencond stage impeller.In a generator
In the case where work, and when only one stage impeller works, the threshold wind velocity 4m/s of blower, rated wind speed 15m/s, survival wind speed
25m/s, rated power 3MW, when only sencond stage impeller works, the threshold wind velocity 3m/s of blower, rated wind speed 10m/s, safety
Wind speed 25m/s, rated power 1.5MW.
Since in the work of low wind speed, the energy loss in the work of the first impeller is larger, and power is low, in order to send out the wind-force
Motor can adapt to large range of wind speed, efficiently use wind-resources, two threshold values involved in the control of above-mentioned wind-driven generator,
First threshold is 6m/s, second threshold 10m/s.
Specific control method is as follows: wind speed is obtained, when wind speed is less than first threshold, to one stage impeller 1 and sencond stage impeller 2
Blade carry out variable pitch, so that one stage impeller 1 is stopped generating state, sencond stage impeller 2 is in rotary electrification state, at first clutch
In meshing state, second clutch is in discrete state.To generate electricity in low wind speeds starting blower, and reduce blower hair
In-fighting in electric process improves generating efficiency.
When wind speed is not less than first threshold and is not more than second threshold, to the blade of one stage impeller 1 and sencond stage impeller 2 into
Row variable pitch makes one stage impeller 1 and sencond stage impeller 2 be in rotary electrification state, and first clutch is in meshing state, second from
Clutch is in discrete state.To carry out high power generation by the first impeller, and remaining wind is efficiently used by the second impeller
Energy.In this mode, the maximum power of blower can reach 4MW.
When wind speed is greater than second threshold, one stage impeller 1 and sencond stage impeller 2 are in rotary electrification state, the first clutch
Device and second clutch are in meshing state.Needed for wind speed is larger than separate unit generator when rated wind speed 10m/s, utilize
Two generators generate electricity simultaneously, and can reach maximum power generation is 8MW, can efficiently use wind energy, improve generated output, and not
The diameter that will increase impeller avoids blade too long, increases manufacture, transport and installation maintenance cost.
Due to being relatively large in diameter for one stage impeller 1, one stage impeller 1 can not be driven to rotate when wind-force is less than first threshold, because
This adjusts the blade of one stage impeller 1, reduces front face area, makes air-flow by one stage impeller 1, directly drives the rotation of sencond stage impeller 2,
And in order to reduce threshold wind velocity, second clutch is in discrete state, and only the first generator works.
When wind-force increases to first threshold and second threshold, the first impeller is also started turning, and is had by the second impeller
It imitates and utilizes remaining wind energy, the revolving speed of the first impeller and the second impeller drives the first generator after wheel speed merges mechanism superposition
Work.
After wind-force continues to be increased above second threshold, since the revolving speed of impeller cannot be promoted infinitely, but driving force is mentioned
Height engages second clutch, while driving the first generator and the second electrical power generators, improves generating efficiency.
In one example, since a Fans have 2 impellers, each blade requires to carry out lightning test, if often
A blade all installs the cost that arrester will greatly improve blower entirety, thus by using the lightning test in embodiment one without
It is man-machine, arrester is only set in unmanned plane, so that it may by an arrester in a unmanned plane to multiple blades into
Row test, greatly reduces blower cost.
