Abstract
The utility model discloses a blade type wind driven generator. The generator comprises a frame and a generator set which is provided with a rotating shaft, wherein the rotating shaft is fixed with a rotating tray which is provided with three blades. A rotating shaft of the generator passes through the rotating tray. A support rod is arranged between each blade and the rotating shaft, so the stability and the strength of the blade are enhanced and the anti-damage capability of the blade is promoted. The width of the blade can be properly increased so as to increase the area of thrust surface of the blade, promote the use ratio of wind and promote the efficiency of the generator.
Description
Technical field
The utility model relates to the technical field of wind-power electricity generation, especially a kind of vane type wind power generator.
Background technique
At present, the wind-driven generator that uses in the world is oar formula generator, and blade is two leaves, three leaves and four leaves, because his is that the stressed blade that promotes of blade face rotates, so wind blade face diameter directly determines the running speed and the efficient of the blade of wind-driven generator.With three oars is example, its three blades are very narrow, the area sum less than with the blade be radius the area of a circle 10%, rotate in order to allow wind push away it, second half of every blade must be to distortion on the other hand, so his wind utilization ratio have only more that the front the wind comes from 5%, four leaves or multileaf type, the utilization ratio of wind is higher, but also relative complex of the increase structure of blade, the weight of fan own is also higher, has influenced the rotating speed of generator.
Chinese patent CN100443719C discloses a kind of wind-driven generator, it forms wind wheel to changeing the blade sheet by one mutually by windward blade and two of leeward blades,, the shared horizontal spindle of two paddle wheel wheel hubs, the intermediate portion of horizontal spindle is a ring-shaped jacket, with pylon top section is that interior cover freely rotates, the multi-disc blade is set and around the horizontal spindle rotation and as the gear of two outputting powers on two tandem wheel hubs, by two horizontal transmission shafts simultaneously with the transmission of power of two wheel hubs to the umbrella tooth of cat head, again by the status generator work in the moving tower of umbrella cingulum.This structure has increased the utilization ratio of wind, but complex structure, cost is higher, is not suitable for a large amount of employings.
Summary of the invention
In order to solve the lower problem of wind utilization ratio of the wind-driven generator that prior art exists, it is a kind of simple in structure that the utility model provides, the small-sized wind power generator that the wind utilization ratio is high.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise frame and generator set, generator set is provided with rotating shaft, fixing rotating disk in the rotating shaft, rotating disk is provided with three blades, it is characterized in that, described rotating shaft runs through rotating disk, is equipped with strut between every blade and rotating shaft.Between every blade and rotating shaft, be equipped with strut, strengthened the intensity of vane stability and blade itself, the survivability of blade is improved, so just can increase the width of blade, increase the utilization ratio of wind, improve the efficient of vane type wind power generator.
As preferably, be fixed with link in the middle part of the described blade surface, link has blade joint and strut joint, and the blade joint is a screw rod, and the strut joint is the U-groove bevel structure, is provided with the connection pin-and-hole in strut joint both sides.The blade joint of link is connected with blade, the strut joint is connected with strut, be provided with pad between blade connection joint and the blade, it is to concentrate for fear of strut and the too for a short time stress that causes of blade area of contact that pad is set, and causes the life-span of blade to reduce.
As preferably, an end of described strut is provided with aperture, and the other end is provided with screw thread, and an end of strut is connected with link, and the other end is connected with rotating shaft.All being connected in the rotating shaft on three blades of strut, rotating shaft, blade and strut form leg-of-mutton structure, and this structure is more more stable, and intensity is higher.
As preferably, described blade lean is arranged on the rotating disk.Blade and rotating disk are the miter angle degree to be arranged, the blade lean setting is in order to increase the stress surface of blade, to increase the utilization ratio of wind.
As preferably, place, the both sides of the edge of described length of blade direction is provided with vertical flanging respectively, and these two vertical flangings stretch out on blade in the opposite direction.The angle degree of flanging and blade is 90 degree, the vertical flanging in both sides is set in order to have strengthened the intensity of blade.
As preferably, be provided with lateral flap in one of blade distolateral edge, lateral flap is perpendicular to the surface of blade.Lateral flap is extended to the blade appearance, and is linked together at the unidirectional vertical flanging of blade surface, makes the blade face be not easy distortion.
The utlity model has beneficial effect:
1, is connected strut on the blade with between the rotating shaft, increased the intensity and the stability of blade of wind-driven generator, and then increased the wind-driven generator weatherliness, prolonged the working life of wind-driven generator.
2, between blade and rotating shaft, be provided with strut, can increase the width of blade, make the vane stress area big, it is just high more to the utilization ratio of wind that the area of blade becomes big blade, so blade is stressed just big more, the big more rotating speed of the equal wind conditions lower stress of blade is just fast more, has increased the power of generator.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of vane type wind power generator is (as Fig. 1,2 is described), comprise support 1, be fixed on the generator set 2 on the support, the rotating shaft 3 that is linked together with generator set, be connected with round turntable 4 in the rotating shaft, rotating shaft runs through rotating disk, blade 5 is obliquely installed in sabot 4, it is trapezoidal tabular that blade 5 is, end at length of blade direction both sides and blade is equipped with flanging, the direction of the flanging of both sides is opposite, blade pitch angle is 45 angles (as shown in Figure 2), and be evenly arranged on the circumference of rotating disk, angle between adjacent two blades is 120 degree, at the middle part of three blades nut 12 fixed connecting pieces 6, link 6 is a U-groove bevel lower end fixing bolt, on U-groove bevel, be provided with pin-and-hole, between link 6 and blade 5, be provided with circular gasket 9 (as shown in Figure 4) between nut 12 and the blade 5, link 6 connects an end of strut 3, strut 3 is cylindrical shaft-like, one end of strut 3 is provided with aperture, the other end is provided with screw thread, the end that strut 3 is provided with pin-and-hole is fixedly connected (as shown in Figure 3) with bolt 13 and link 6, the other end of strut 6 is connected with rotating shaft 7, strut 3, blade 5 and rotating shaft 7 forms triangular structures, is provided with conical upper shield 14 at the axle head of rotating shaft.
This generator is provided with strut 3 between blade 5 and rotating shaft 7, the intensity and the anti-broken transducing power of blade 3 have been strengthened, so the broad that blade 3 can be done, blade 3 lifting surface areas increase, and the utilization ratio of wind increases, under equal wind conditions, wide blade is bigger than narrow leaf wind-driven generator lifting surface area, so stressed also bigger, stressed big, the startup of generator is also very fast so, and rotating speed also is higher than the rotating speed that narrow blades is separated generator.
