Abstract
The utility model discloses a vertical axis wind driven generator vane. The vane has the characteristics of resistance and elevating force. The vertical axis wind driven generator vane is characterized in that the vertical axis wind driven generator vane is composed of front, middle and rear sections, wherein a gap is reserved between every two sections, the vertical axis wind driven generator vane has the resistance characteristics when the velocity ratio of the vane tip is smaller than 1, the air current generates the elevating force and passes through the gaps to be ejected to the lower pressure area from the high pressure area when the velocity ratio of the vane tip is larger than 1, and the direction of counterforce is the same as that of vane rotation, so that the rotary torque is increased, the positive pressure of air to the vane is reduced, and the safety is improved.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, especially a kind of vane of vertical shaft wind-driven generator.
Background technique
Vertical axis aerogenerator mainly contains resistance type and lift-type.Resistance type is to utilize air stream in the resistance work done that blade produces, and has bigger commentaries on classics and turns round and good startability, but have tip speed ratio and the low problem of wind energy transformation rate.Lift-type is to utilize the pressure difference that air stream produces blade and the lift work done that forms has higher tip speed ratio and wind energy transformation rate, but have the problem that is difficult to start under the low wind speed.And the lift-type blade is perpendicular to the radial direction setting, can be subjected to bigger alternate load, and wind speed is high more, and the wide more alternate load of blade is big more, so have safety and the problem that requires high performance material.
Summary of the invention
The problem of mentioning in order to solve in the background technique, the utility model provide the efficient vertical axis wind turbine blade of a kind of safe and reliable, easy startup, high tip speed ratio.
Blade described in the utility model is combined by leading portion, stage casing, back segment three parts.Leave the slit between section and the section.Its cross-sectional profiles line is respectively: leading portion is that two coaxial not parfocal parabolas are formed by two skew lines interceptings.The stage casing is that symmetry or asymmetric airfoil streamline are formed by parabola intercepting.Back segment is symmetry or asymmetric airfoil streamline.The aerofoil profile streamline of its posterior segment is the approximate extension of stage casing aerofoil profile streamline.The main geometric parameters of above-mentioned blade is: the pattern length b of stage casing and back segment and the ratio of chord length a are 0.85-0.9, the ratio of preceding segment length c and chord length a is 0.25, the width d of leading portion and the ratio of chord length a are 0.25, minimum place, slit is 1/16 of chord length a apart from e between leading portion and the stage casing, and minimum place, the slit between stage casing and the back segment is 1/18 of chord length a apart from f.
Design principle of the present utility model is: when tip speed ratio less than 1 the time, air stream produces resistance in the slit between section and section, promotes blade rotation.When tip speed ratio greater than 1 the time, air stream is sprayed to low pressure area by the zone of high pressure through the slit when producing lift, its reaction force is identical with the blade sense of rotation.So increased running torque.Reduced the positive pressure that air stream produces blade simultaneously.So it is blade of the present utility model has resistance and lift efficiency, safe and reliable, efficient is high.
