Abstract

The utility model discloses a windmill blade of a vertical-axis wind turbine. The windmill blade comprises an upper blocking plate, a lower blocking plate and the connecting end, wherein the windmill blade is connected with the wind turbine through the connecting end. The vertical-axis wind turbine is characterized by further comprising a front sailboard and a rear sailboard, wherein the front sailboard and the rear sailboard are connected to form a connecting angle, and the upper blocking plate and the lower blocking plate are respectively connected at the top and the bottom positions of the front sailboard and the rear sailboard, the front sailboard and the rear sailboard are blown by wind, and the windmill blade rotates. The windmill blade is simple in structure, convenient to install and free of noise and is started at low wind speed. Compared with the same type of wind turbine windmill blades, the windmill blade is high in working efficiency, is commonly suitable for areas with good wind energy conditions and away from a power grid or where the power grid is unnormal and provides illumination power for televisions and searchlights.

In order to address these problems, investigation and research through certain hour, under a collection of expert's of Ge colleges and universities cooperation, successfully developed a Novel vertical axis wind turbine, and installation success of the test, basic data and practical experience obtained, in follow-up time, product is improved many times and tested, and product has passed through every test, and has reached every designing requirement.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is in order to reduce the noise of wind-driven generator, and reduces equipment loss as far as possible.
The utility model provides a kind of vertical axis aerogenerator air vane, the technological scheme that the utility model adopts is: a kind of vertical axis aerogenerator air vane, include front windsurfing, overhead gage, rear windsurfing, lower pedal, connecting end, connecting end is connected with wind-driven generator, its function of connecting end is that the mechanical energy that air vane is produced passes to wind-driven generator, front windsurfing, rear windsurfing connects into an angle of attachment, before, the setting of rear windsurfing is in order to have increased the area of contact of wind-force and windmill, before, it is to be provided with a deceleration ramp as wind-force that rear windsurfing take that angle of attachment connects, this deceleration ramp for air vane when work instantaneous wind-force provide a buffering to make the air vane can be evenly for wind-driven generator provides mechanical energy, overhead gage and lower pedal are connected to front windsurfing, the top of rear windsurfing and bottom position, windsurfing before wind blows, rear windsurfing, air vane rotates provides mechanical energy for wind-driven generator.
Further improvement of the utility model is: can have good buffer function when guaranteeing wind to front windsurfing and rear windsurfing, the angle of attachment 8 of front windsurfing and rear windsurfing is obtuse angle.
Further improvement of the utility model is: in order to obtain wind-force comparatively uniformly, front windsurfing 1, rear windsurfing 4 are evenly equipped with windsurfing 2, each windsurfing 2 is fixed on front windsurfing 1, rear windsurfing 4 by the axle corresponding with it 6, windsurfing 2 is movable structure, and when wind-force is blown over, windsurfing 2 rotates power is provided around axle 6.
Compared with prior art, the beneficial effects of the utility model are: the utility model has been taked the windward side as air vane with the assembled by combining two junk of several angle, have increased the wind-exposuring area of air vane, have reduced the loss of air vane; The utility model has also adopted the form of uniform movable windsurfing on front windsurfing and rear windsurfing, makes the amount of collecting folk songs of air vane more even, has reduced the noise that air vane sends.
The utility model is simple in structure, easy for installation, and low wind speed starts, noise free, and higher than wind power generation windmill blade working efficiency of the same type, it is good that it is generally applicable to wind energy condition, away from electrical network, or the abnormal area of electrical network, supply with illumination, television set, searchlight.
