Abstract
The invention relates to a resistance and lift compound wind power device, in which the wing airfoil-vane of the wind wheel being a special structure with a curved surface is made of sheet. A plurality of air vanes are fixed on the rotation axis of the wind wheel being as the torque output shaft via a link rod. The intersection angle between the chord of each airfoil-vane and the link rod fixing the vanes is an angle of 60~70 degrees. Its character is that the wind vane has the compound action of resistance and lift. When the line speed of the wind vane approaches to the rated wind speed, the backward resistance produced by the wind vane and the quadratic of the relative wind speed of the wind vane forms direct proportion, so that it has automatic speed-limiting function.
Description
Technical field
The present invention relates to a kind of is the pivotal axis resistance of mechanical energy and lift hold concurrently all comprehensive wind force device-resistance and lifting force composite wind pwoer device with wind energy transformation.
Background technique
The wind wheel apparatus of existing wind-driven generator has two types of horizontal axis and pivotal axis wind wheels: horizontal-shaft wind turbine is to adopt the propeller wind wheel, and lift is converted to rotating shaft moment.Because this form starting wind velocity height, need be to wind direction device and speed limiting device, that the maintenance difficulty is installed is bigger so make, the expense height.
The structure of vertical-shaft wind-power machine is divided into the wind wheel of resistance type and two kinds of forms of lift formula.The resistance type of one of them is to utilize the difference of face and adverse wind face with the wind to form the torsional moment of main shaft.This form simple in structure, but low to wind power utilization efficient.Other has the representational Da Lie formula wind power apparatus of lift formula to still have problems such as starting wind velocity height and need speed limiting device.
In a word, prior art can only be limited to the single resistance that utilizes fan blade or the structural type of lift to the wind wheel of wind energy conversion system.
Summary of the invention:
The purpose of this invention is to provide a kind of resistance and lifting force composite wind pwoer device, to remedy the deficiencies in the prior art.
The present invention is on the basis of prior art, it mainly is improvement to the wind wheel of wind-driven generator, the air-foil fan blade of its wind wheel is the abnormally-structured body of the concave curvatures made of a thin plate, hollow aerofoil profile fan blade lower surface vacancy, and rely on link rod by axial uniform being fixed on the wind wheel running shaft by a plurality of fan blades, the lower surface of the aerofoil profile of fan blade outwardly, the string of each aerofoil profile fan blade is 60 °-70 ° with the angle of fixing the link rod of this fan blade.
Consider easy to assemblyly, the fan blade of above-mentioned wind wheel can be the even number fan blade and rely on link rod to be fixed on the wind wheel running shaft by axial symmetry.
Fan blade of the present invention possesses resistance and lift compound action, need not be provided with the wind direction device, easily start when hanging down wind speed, the common wind wheel that drives of starting back resistance and lift stack, when the linear velocity of fan blade during near specified cut-out wind speed, fan blade produces reverse resistance automatic speed-limiting, and does not need to establish specially to add speed limiting device again.

Embodiment
The air-foil fan blade 1 of its wind wheel of the present invention is the abnormally-structured body of the concave curvatures made of a thin plate, the aerofoil profile lower surface A vacancy of hollow aerofoil profile fan blade 1, and rely on link rod 2 by on the axial uniform wind wheel running shaft 3 that is fixed on as the moment output shaft by a plurality of fan blades 1, the aerofoil profile lower surface A of fan blade 1 outwardly, the string of each aerofoil profile fan blade 1 is 60 °-70 ° with the angle theta of fixing the link rod 2 of this fan blade 1, the affects drag effect at θ angle and the size and the ratio of lift effect, selection during practical application, should select according to the wind behaviour of locality, usually annual mean wind-force below 3 grades more than 60 days the time, should get bigger than normal or be advisable near CLV ceiling limit value by the θ angle.
1 of above-mentioned wind wheel can be the even number fan blade and rely on link rod 2 to be fixed on the wind wheel running shaft 3 by axial symmetry.
The thin plate of above-mentioned making fan blade can be metal and plastics, and described fan blade 1 is an all-in-one-piece overall structure, can utilize injection moulding or stamping process once to make.Should guarantee on the technology fan blade is securely fixed on the link rod, again because fan blade is a complete integrative-structure, the stability of fan blade itself and intensity height.
As Fig. 1, when the aerofoil profile lower surface A of fan blade facings the wind, maximum and the stressed maximum of its frontal resistance, and the streamlined of another fan blade that is on the symmetrical position forward facings the wind, the resistance minimum, therefore can produce bigger driving moment to wind wheel running shaft 3, and when its angle of attack increased gradually by 0 °, the lifting moment that the aerofoil profile fan blade produces strengthened gradually, produced the maximum lift square when the angle of attack reaches 20 °, both synergies promptly are the compound actions of resistance and lift.
The wind speed of constructing thus of the present invention can start at the low wind speed of 3 meter per seconds.The common wind wheel that drives of starting back resistance and lift stack, when the linear velocity of fan blade during near specified cut-out wind speed,, the reverse resistance that fan blade produces is directly proportional with the quadratic power of the relative speed of wind of fan blade, thereby the effect with automatic speed-limiting does not need to establish specially to add speed limiting device yet again.
