Description

A kind of horizontal axis wind-driven generator
Technical field
The utility model relates to horizontal axis wind-driven generator.
Background technique
The memory space of non-renewable energy resources is fewer and feweri now, therefore, needs some renewable energy sourcess of demand or the new energy to substitute non-renewable energy resources.Wherein, wind energy is exactly a kind of in renewable energy sources, this using energy source environmental protection of getting up, and its application will be more and more extensive.
Now, to Wind Power Utilization maximum be wind-power electricity generation, at present the equipment of wind-power electricity generation mainly contains two kinds of horizontal axis wind-driven generator and vertical axis aerogenerators.Wherein, horizontal axis wind-driven generator is mainly comprised of king-post, generator and wind wheel.Generator is arranged on king-post, wind wheel is arranged on generator, wind wheel rotation can make generator work, therefore, the structure of wind wheel, intensity etc. have played very important effect in horizontal axis wind-driven generator, and in order to solve the technical problem producing because of wind wheel, people have carried out many research to wind wheel.As at application number being discloses a kind of diffuse type wind wheel in the patent documentation for 2012.5.30 in 201010555574.7 open days, and specifically disclose diffuse type wind wheel by wheel hub, blade and wheel rim form, although it is simple in structure, in the situation that not increasing rotor diameter, can improve to greatest extent the available power of wind wheel, use safety and stability, noise is little, and can increase significantly flow and power, but, the variation of the position box haul of wind wheel changes, therefore, the all directions of blade are all likely stressed, and inhomogeneous, and blade is rectangular with the cross section that is connected of wheel hub, in this case, connection part between blade and wheel hub easily produces gyroscopic effect, easily fracture between blade and wheel hub, therefore, intensity is low.
Model utility content
For the join strength of blade and wheel hub is improved, the utility model provides a kind of horizontal axis wind-driven generator.
For achieving the above object, a kind of horizontal axis wind-driven generator, comprises tower bar, electric machine casing, tail vane, end cap, motor stator, rotor and wind wheel; Electric machine casing is provided with in king-post, and tail vane is located at the rear portion of electric machine casing, and end cap is located at the front end of electric machine casing, and motor stator is arranged in electric machine casing, and rotor is located in motor stator, and the output shaft of rotor is through end cap and stretch out end cap; Wind wheel is located on the external part of rotor output shaft; Described wind wheel comprises wheel hub, blade and wheel rim, and one end of blade is connected on wheel hub, and wheel rim is enclosed within on the blade tip of blade; The cross section of root of blade is oval.
Said structure because the cross section of root of blade is oval, links together blade tip by wheel rim simultaneously, and blade is difficult for distortion, when wind wheel is in rotary course, root of blade surrounding stressed evenly, therefore, improved the join strength of blade and wheel hub.Because wheel rim links together blade tip, therefore, wind wheel vibration of blade tip in rotary course is little, thereby reduced noise content, and wheel rim can reduce the displacement amount that blade is waved direction, thereby reduce the loss of blade tip position wind energy, therefore, improved the utilization ratio of wind energy.Described blade couples together wheel hub and wheel rim, has played the effect of web frame, and therefore, the intensity of whole wind wheel is good.
Further, between root of blade and wheel hub, be provided with transition arc, can further improve the join strength between wheel hub and blade.
Further, at the back side of blade, be provided with noise reduction line, the noise while working to reduce wind wheel.
Further, wheel hub, blade and wheel rim are structure as a whole, like this, low cost of manufacture, and intensity is high.
Further, on wheel hub, be provided with lightening hole, to alleviate the weight of wheel hub.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1 to Figure 3, horizontal axis wind-driven generator comprises king-post 1, electric machine casing 2, tail vane 3, end cap 4, motor stator 5, rotor 6 and wind wheel 7.
In electric machine casing 2, have cavity 21, cavity 21 can alleviate the weight of electric machine casing on the one hand, on the other hand for accommodating motor stator 5 and rotor 6.The middle part of electric machine casing is arranged on king-post 1.Tail vane 3 is located at the rear portion of electric machine casing 2, and one-body molded with electric machine casing 2.Described end cap 4 is arranged on the front end of electric machine casing 2.Described motor stator 5 is arranged on the inwall of electric machine casing 2, and rotor 6 is located in motor stator 5, and rotor 6 has output shaft, and output shaft stretches out end cap through end cap 4, between output shaft and end cap 4, bearing is set.
As shown in Figures 1 to 4, described wind wheel 7 comprises wheel hub 71, blade 72 and wheel rim 73.Wheel hub 71 centers have hole 711, for output shaft is installed; The outside that the end face of wheel hub 71 is positioned at hole 711 is provided with lightening hole 712, and this structure can alleviate the weight of wind wheel on the one hand, and the load of wind wheel is reduced, and can also improve on the other hand the intensity of wheel hub.Described blade 72 comprises root of blade 721, blade middle part 722 and the blade tip 723 connecting successively, as shown in Figure 6, the cross section ovalize of root of blade 721, wherein the ratio of oval-shaped major diameter and minor axis is 1:0.8-0.99, blade and wheel hub are one-body molded, between root of blade 721 and wheel hub 71, be provided with transition arc, to improve join strength; As shown in Figure 7, at the back side of blade, be provided with noise reduction line 724, the noise in the time of reducing wind wheel work.Wheel rim 72 is enclosed within on the blade tip 723 of blade.
As shown in Figure 1 to Figure 3, the outside that is positioned at wind wheel 7 on output shaft is connected with fair water cone 9 by bolt 8.
Present embodiment because the cross section of root of blade 721 is oval, links together blade tip 723 by wheel rim 73 simultaneously, blade is difficult for distortion, in wind wheel 7 rotary courses, root of blade 721 surroundings stressed evenly, therefore, improved the join strength of blade and wheel hub.Because wheel rim 73 links together blade tip 723, therefore, wind wheel 7 vibration of blade tip in rotary course is little, thereby reduced noise content, and wheel rim can reduce the displacement amount that blade is waved direction, thereby reduce the loss of blade tip position wind energy, therefore, improved the utilization ratio of wind energy.Described blade couples together wheel hub and wheel rim, has played the effect of web frame, and therefore, the intensity of whole wind wheel is good.
