Abstract
The utility model provides an impeller structure of a wind driven generator, which mainly comprises a plurality of blades fixed on the outer circumference of the excircle of an impeller ring. The blades are formed by a plurality of long blades and short blades, the long blades and the short blades are distributed in gravity balance mode, thereby being light in weight, capable of fast starting rotation, improving born wind power and lowering cost.
Description
[technical field]
The utility model is the blade wheel structure about a kind of wind-driven generator, refers to a kind of plurality of vanes of impeller especially, is made up of a plurality of long and short blade; Long and short blade distributes with the gravity balance mode; Tool is in light weight, can start rotation fast, and lifting is contracted wind-force, can be reduced cost.
[background technique]
Wind energy is to offer human a kind of available energy because of air flow.The kinetic energy that air-flow has is claimed wind energy, and air velocity is high more, and kinetic energy is big more, and people can be converted into the action of rotation with the kinetic energy that windmill is kept watch and remove pushing generator, to produce electric power; The structure of convention wind-driven generator mainly is the affixed blade wheel hub of transmission shaft one end of the generator that is fixed, the turbine blade that the fixing more outwards radiation of wheel hub side face is extended.Wherein, blade is to utilize the wind-force driven rotary, converts wind energy to mechanical energy, is the system output power through power conversions, makes electric power and stores or be used.Above-mentioned wind-driven generator; Blade outwards radiates extension by the wheel hub periphery, and blade wheel hub center portion is because of the paraxial heart, and it is little to endeavour square; And turbine blade directly is fixed on the wheel hub of generator drive axle; Turbine blade less (approximately only 3-6 sheet) can produce that useful area is few, efficient difference and toggle speed be slow, the disappearance that makes cost improve.
The utility model people improves above-mentioned disappearance because above-mentioned convention wind-driven generator has above-mentioned disappearance existence on using, simultaneously patent applied for (case before being called for short).But the length of preceding each blade of case is identical, and length of blade is if design is shorter, though it is very fast to start the impeller rotational speed, impeller axle center rotary torsion is less relatively, and it is also less to drive generator for electricity generation power; Opposite, if the length of blade design is longer, though it is big to contract the wind-force area, impeller weight is heavy, and relative startup rotational speed can be slower, and meet the less situation of wind-force, and impeller possibly can't rotate, and these problems obviously have much room for improvement.
[model utility content]
The purpose of the utility model provides and a kind ofly can promote the blade wheel structure that wind-force is contracted area, in light weight, the large wind generator that can reduce manufacture cost.
A kind of blade wheel structure of wind-driven generator, it comprises:
One wheel hub;
One wheel rim is located at the wheel hub outside and is done the concentric setting with wheel hub;
Plural number Zhi Gangsi is that radial arrangement is fixed between wheel hub and the wheel rim, and an end and wheel hub side face are fixed, and the other end and wheel rim inner face end are fixed, with the wheel rim support fixation; And
The plural number blade is to be fixed on the wheel rim periphery with the radiation arrangement mode, and pulling the wind fixed angle, and the gravity balance mode distributes;
It is characterized in that: these blades are made up of long and short blade.
Wherein, be to make the isogonism arranged distribution to fix between the linear leaf or between the short blade.
Wherein, has an axis hole in the middle of this wheel hub, in order to combine the transmission shaft of generator set.
Wherein, wheel rim is interior empty shape, and is made by the composite wood of high tenacity and light weight.
The utility model advantage and effect are: provide a kind of can promote wind-force contract area, in light weight, can start rotation fast, and promote and to contract wind-force, can reduce cost.

Label declaration is following among the figure:
Outside thread 111 pilums 12 wheel rims 13 nuts 20
[embodiment]
Please consult simultaneously shown in Fig. 1-2, the impeller of the utility model wind-driven generator is to comprise:
One wheel hub 10 is affixed with transmission shaft 110 1 ends of generator set 11, has an axis hole 100 (as shown in Figure 3) in the middle of the wheel hub 10.Generator set 11 bottoms are provided with a pilum 12; Transmission shaft 110 front ends of generator set 11 have an outside thread 111; After making transmission shaft 110 stretch in the axis hole 100 of wheel hub 10; Solid by the outside with a nut 20 and outside thread 111 spiral shells, the wheel hub 10 of impeller is fixed on the transmission shaft 110 of generator set 11;
One wheel rim 13, for interior empty shape, made by the composite wood of high tenacity and light weight; Be located at wheel hub 10 outsides and wheel hub 10 and do the concentric setting; Wheel rim 13 peripheries are fixed with the blade 14 that a plurality of radiation are arranged, and these blades 14 are made up of 14 in long and short blade, and long and short blade 14 distributes with the gravity balance mode; That is make the isogonism arranged distribution between the linear leaf 14 or between the short blade 14, and blade 14 is pulled the wind fixed angle with wheel rim 13; And
Plural number Zhi Gangsi 15 is that radial arrangement is fixed between wheel hub 10 and the wheel rim 13, and an end and wheel hub 10 side faces are fixed, and the other end and wheel rim 13 inner face ends are fixed, and wheel rim 13 is combined with wheel hub 10 to support and fix.
After above-mentioned member is made up in regular turn, promptly like Fig. 1, shown in 2 and 4, wind-drive blade 14 rotation, and then make generator set 11 generatings reaches the effect of wind-power electricity generation.
Owing to have following improvement on the utility model structural design, it is following to produce effect:
1, because of wheel rim 13 inside are steel wires 15, cause wheel rim 13 centers and pull the inefficient place of wind, area is little, and wind-force is little through resistance, and light weight, and wheel rotation is easy.Blade 14 is arranged at wheel rim 13 peripheries from wheel hub 10 1 segment distances, and it is good that blade 14 is pulled the wind effect, and the impeller rotary torsion is big, and generator set 11 efficient are high.
2, linear leaf 14 can be contracted bigger wind-force, increases the impeller rotary torsion; Short blade 14 can reduce impeller weight, makes impeller be prone to start.
3, wheel rim 13 is evenly supported by steel wire 15, and not only supporting structure property is good, and can be by adjustment steel wire 15 adjustment wheel rims 13 balances, make the impeller rotation more steadily, not eccentric.
