Technical field
The present invention relates to a kind of blade of wind-driven generator, in particular to a kind of utilization gas shock tension, and impeller to be pushed to rotate
Blade of wind-driven generator.
Background technology
By the blade installed on wind-driven generator, wind energy is first converted into rotating mechanical energy, then is converted by generator
For electric energy.In the conversion process of wind energy to electric energy, blade play the role of it is vital, it shape design directly affect wind
The generated energy of power generator and wind-powered electricity generation transformation efficiency.Currently, for relative atmospheric airflow direction, horizontal shaft type wind-driven generator leaf
The windward side of piece is equipped with certain inclination angle, and insider is referred to as the angle of attack, after air draught impacts the blade at inclination angle,
Blade makes blade generate the tangential force of periphery around trunnion axis rotation under the action of air-flow, to which wind energy is converted into rotation
Mechanical energy.The direction for changing power using inclination angle, is rigid dynamics concept, and wind is that have fine mobility under the conditions of space opening
Air fluid, for hydrodynamics concept, fluid is to transmit kinetic energy by pressure, changes the direction of power and need not be arranged and incline
Angle.In addition, the air draught as wind energy is a kind of potential energy, it is changed into kinetic energy, unique method there is the air-flow of certain potential energy
It is to make flow slowing down to stopping, when the complete stop motion of air-flow, potential energy could realize the complete conversion of kinetic energy, reach kinetic energy energy
The maximum value of amount.After when gas shock to the blade equipped with inclination angle, air-flow at this moment is substantially to slow down to flow through blade, and air-flow cannot
Stop completely, blade is also impossible to obtain the kinetic energy of bigger, by Bernoulli Jacob's wind pressure equation：, before rated wind pressure
The condition of carrying is exactly to stop that the plane of air-flow must be perpendicular to airflow direction.
Current horizontal axis wind-driven generator has been that more ripe power generation is mechanical, but passes through after decades of development
The above-mentioned analysis to blade tilt, wind-powered electricity generation transformation efficiency are still greatly improved space.

The lower end edge of trapezoidal plate is trapezoidal top margin, and is set as the lower edge of blade plane plate.
Compared with prior art, the major design of the present invention blade of a topology update, it is the leaf by being seamlessly connected
The compositions such as plate plane plate, drag board and upper surface plate, the windward side of the blade plane plate was not only vertical with wind direction, but also the rotation with blade
It is parallel to turn plane, wind at that time can be obtained when the windward side of air-flow vertical impact blade plane plate according to hydrodynamics concept
Can highest wind pressure it is strong, while also producing on the windward side of blade plane plate air tension around, the air tension
It can contact and tension plate shape testing pushed to be rotated at one direction, that is, drive the rotation of impeller；In addition, upper surface plate is by opening
The top of power plate extends forward, and surface plate is parallel to blade plane plate simultaneously on this, therefore can reduce sky when blade rotation
Atmidometer.Therefore, by designing the blade construction of this one-way movement, wind energy can be more preferably realized to rotating machinery transformation of energy,
And then atmospheric pressure is efficiently used, and the transformation efficiency of wind-powered electricity generation is increased substantially, especially increase substantially low wind speed
When generated energy.Improved blade also has many advantages, such as that structure is simple to manufacture, is easy for installation, is of low cost.
