Abstract
The invention discloses a windmill wind blade with multiple blades on an outer ring, which has a large wind-engaging area, high pneumatic performance and high conversion efficiency of wind energy and can regulate the wind-engaging area of the wind blade automatically. The wind blade comprises a windmill hub (1), a spoke-shaped skeleton pipe (3), an annular skeleton ring (2) and a main blade group on the outer ring of the annular skeleton ring, wherein the spoke-shaped skeleton pipe (3) is connected between the windmill hub (1) and the annular skeleton ring (2); a cavity (4) is formed inside the annular skeleton ring (2); and a blade shaft base (7), a thrust bearing (9) and a torsional spring (10) are arranged in the cavity (4) and are used for mounting the main blade group outside the annular skeleton ring.
Description
Technical field
The present invention relates to a kind of windmill wind sizing device.
Background technique
Windmill is utilizing field extensive uses such as wind energy power.Existing windmill mostly is three leaf wind slurries, its shortcoming is that wind slurry paddle is few, the paddle blowing area is little, to the air-flow delay of response, pneumatic property is poor, poor to the absorption transfer capability of wind energy, efficient is low.
Summary of the invention
For overcoming the defective of above-mentioned prior art, technical problem to be solved by this invention provides a kind of outer ring many paddles windmill wind slurry.Its blowing area is big, and pneumatic property is strong, to wind energy conversion efficiency height, can regulate the blowing area of wind slurry automatically.
The present invention adopts the basic design of technological scheme to be:
The present invention includes the main blade group of windmill wheel hub, spoke shape skeleton pipe, ring skeleton circle and ring skeleton circle outer ring, spoke shape skeleton pipe connects between windmill wheel hub and ring skeleton circle, ring skeleton circle inside is provided with cavity, is provided with blade axle bed, thrust-bearing and torque spring in the cavity and is used for installing the outer main blade group of annular skeleton ring circle.
Wherein, described cavity tangent plane is a quadrilateral, and its insole binding is 25 °～30 ° with long hypotenuse angle, and long hypotenuse and last short hypotenuse angle are 70 °～75 °.
Wherein, chuck is set also between blade axle bed and the sharf, the blade axle bed is provided with dop, and chuck, dop cooperatively interact and control the maximum angle that paddle shaft rotates.
Wherein, main blade blade face radian is not more than 30 °, and paddle shaft is positioned at blade face 0.6～0.7 and highly locates.
Wherein, metaplasm leaf group is set on ring skeleton circle inner ring is domatic, the metaplasm leaf is 40 °～50 ° with described wind slurry diameter angle vertically, from bottom to top points to described wind oar sense of rotation domatic; The height of metaplasm leaf from bottom to top progressively is decremented to zero.
The invention has the beneficial effects as follows that ring skeleton circle Internal and external cycle is provided with two groups of paddles of major-minor respectively, and blade quantity is many, the blowing area of windmill wind slurry is big like this, starts rapidly; The outer ring paddle self has possessed the effect of good power arm, and pneumatic property is strong, to the conversion efficiency height of the wind energy that absorbed; The outer ring paddle can be that axle is done axial motion with the paddle shaft, can regulate the absorption to wind energy automatically, so windmill wind slurry operates steadily; And the linkage structure steadiness of windmill wheel hub, spoke shape skeleton pipe, ring skeleton circle is strong, reliable.
