Abstract
The utility model provides an automatic paddle-adjusting device of a vertical-axis wind turbine, which comprises a wheel hub and at least two groups of impellers arranged around the wheel hub. Each impeller comprises a wheel arm and a blade which is movably connected with a vertical rod in the wheel arm and is fixedly connected with blade noses, the blade noses are sleeved on the vertical rod, and an elastic adjusting component is arranged between one blade nose and one connecting rod of the wheel arm. When the wind turbine is started, the blades can swing, the elastic adjusting components can be driven by the blade noses to be stretched when the blades swing, the tension of the elastic adjusting components increase along with increase of the rotating angle of the blades, the blades are finally pulled back to be in a state vertical to the wheel arms under the tension of the elastic adjusting components, and the rotating range of the blades is limited. Therefore, the impact of the blades on the wheel arms caused by the large rotating angle of the blades can be avoided, the purpose of adjusting paddles through the blades can be achieved, and the vibration, the noise and energy losses caused by impact of the blades and the wheel arms can also be avoided.
Description
Technical field
The utility model relates to a kind of vertical axis windmill, especially a kind of automatic blade adjusting device of vertical axis windmill.
Background technique
At application number is " 200810017055.8 ", name is called in the application for a patent for invention of " magnetic suspension paddle distance self-adjusting vertical shaft wind power generator ", disclose a kind of structure of paddle distance self-adjusting: each of wind energy conversion system taken turns arm and is made up of two connecting rods up and down and the vertical rod of fixedlying connected with two connecting rod ends, blade is hinged with the vertical rod of wheel arm one end, this mode that is rotatably connected between blade and the vertical rod has realized that blade can adjust propeller pitch angle automatically in the wheel rotation process.But, when wind-force hour (when beginning to start) as wind energy conversion system, wind energy conversion system does not also produce enough centrifugal force makes blade and wheel keep plumbness between the arm, at this moment, swing can appear in blade, if amplitude of fluctuation is bigger, will the starting of wind energy conversion system be had a negative impact, make blade and wheel arm bump the produce power loss.Existing in prior technology deficiency that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of automatic blade adjusting device that can avoid the vertical axis windmill of blade and wheel arm bump effectively is provided.
This programme is realized by following technical measures: the automatic blade adjusting device of this vertical axis windmill comprises at least two group impellers that wheel hub and wheel hub periphery are provided with, described impeller comprises wheel arm and the blade that flexibly connects with the vertical rod of taking turns in the arm, be fixedly connected with leaf-nosed on the described blade, be provided with the flexible adjustment part between leaf-nosed being sleeved in the vertical rod, the leaf-nosed and connecting rod of wheel in the arm.
The set-up mode of above-mentioned flexible adjustment part can adopt following form: leaf-nosed and wheel in the arm upper connecting rod and/or lower connecting rod between be provided with the flexible adjustment part.
Above-mentioned flexible adjustment part adopts spring, and is simple in structure, realize easily, and cost is low.
In order to realize better adjusting effect, above-mentioned flexible adjustment part and upper connecting rod and the projection of lower connecting rod on horizontal plane are point-blank.
Above-mentioned flexible adjustment part arranged outside has protective coating, and protective coating can prevent the phenomenon that the flexible adjustment part occurs getting rusty through exposing to the weather effectively.
In order to reduce cost, above-mentioned protective coating adopts rubber layer.
The beneficial effect of this programme can learn according to the narration to such scheme, in the automatic blade adjusting device of this vertical axis windmill, is fixedly connected with leaf-nosedly on the described blade, and leaf-nosed being sleeved in the vertical rod is provided with the flexible adjustment part between the connecting rod in the leaf-nosed and wheel arm.When wind energy conversion system starts, swing can appear in blade, extend by leaf-nosed drive flexible adjustment part during blade oscillating, increase along with the blade rotation angle, it is big that the pulling force of flexible adjustment part becomes, finally the pulling force by the flexible adjustment part is withdrawn into the state vertical with taking turns arm with blade, thereby limited the slewing area of blade, avoided because the blade rotation angle is excessive, and blade occurs and take turns the situation that arm clashes into mutually, reached blade and transferred the purpose of oar, thereby also avoided because vibration, noise and the energy loss that blade and the bump of taking turns arm occur.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Fig. 2 is the structural representation of one group of impeller among Fig. 1.
Fig. 3 is the view of blade in rotating a circle.
Among the figure, 1 is wheel hub, and 2 is upper connecting rod, and 3 are the wheel arm, and 4 are vertical rod, and 5 is blade, and 6 is lower connecting rod, and 7 is pylon, and 8 is generator, and 9 is impeller shaft, and 10 is impeller, and 11 is leaf-nosed, and 12 is spring, and 13 is rubber layer.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by embodiment.
A kind of automatic blade adjusting device of vertical axis windmill, as Fig. 1, Fig. 2 and shown in Figure 3, it comprises at least two group impellers 10 that wheel hub 1 and wheel hub 1 periphery are provided with, described impeller 10 comprises that wheel arm 3(wheel arm 3 comprises upper connecting rod 2, the vertical rod of fixedlying connected with lower connecting rod 6 with upper connecting rod 2 respectively in lower connecting rod 6 and two ends 4) and with vertical rod 4 in the wheel arm 3 flexibly connect the blade 5 of (as hinged), be fixedly connected with on the described blade 5 two leaf-nosed by 11, two leaf-nosed 11 two ends that are set in vertical rod 4, leaf-nosed 11 and wheel in the arm 3 upper connecting rod 2 and/or lower connecting rod 6 between be provided with flexible adjustment part (as spring 12), flexible adjustment part and upper connecting rod 2 and the projection of lower connecting rod 6 on horizontal plane are point-blank, flexible adjustment part arranged outside has protective coating, and this protective coating adopts rubber layer 13.
During the wind energy conversion system starting, also do not have enough centrifugal force to make between blade 5 and the wheel arm 3 and keep plumbness, swing can appear in blade 5, during blade 5 swings, drive spring 12 elongations by leaf-nosed 11 and produce pulling force, increase along with blade 5 rotation angles, it is big that the pulling force of spring 12 becomes, finally the pulling force by spring 12 is withdrawn into the state vertical with taking turns arm 3 with blade 5, thereby limited the slewing area of blade 5, avoided because blade 5 rotation angles are excessive, and blade 5 and wheel arm 3 mutual situations of clashing into have occurred.
In the wind energy conversion system rotary course, blade 5 under action of centrifugal force away from gyration center, at this moment, wheel arm 3 can produce pulling force and centrifugal force balance, two power point-blank, and size is identical, direction is opposite, the projection of leaf-nosed 11 gyration center just in time is positioned on this straight line, at this moment, spring 12 is (inoperative) in the raw, and centrifugal force forces blade 5 to keep the state vertical with taking turns arm 3, and the rotating speed of wind energy conversion system is high more, the centrifugal force of blade 5 is big more, and what plumbness kept between blade 5 and the wheel arm 3 is good more.
Can pass through existing techniques in realizing without the technical characteristics of describing in the utility model, not repeat them here.
