Abstract
A kind of vane of vertical shaft wind-driven generator, be the perpendicular blade putting work, the cross section of this blade is the asymmetric air-foil that outer side surface camber is greater than inner side surface camber; The upper and lower of this blade is straight blades section, the curved vane section of middle part for being convexly curved laterally, and the thickness of its curved vane section up and down by centre is successively decreased and to connect with upper and lower straight blades section smooth transition in two ends, form that upper and lower is straight blades section, middle part is the straight of curved vane section and bending combined blade; Be provided with opening at the middle part of this blade and be positioned at choke chamber inside trailing edge.Technological scheme of the present invention also comprises: the leading edge in the middle part of described blade and trailing edge are distinguished curved outwardly, form the blade not waiting width; Described blade is arranged to hollow structure.The present invention, compared with existing vane of vertical shaft wind-driven generator, has larger torque, higher tip speed ratio and wind energy transformation rate, and good startability.
Description
Technical field
The present invention relates to wind-driven generator, be specifically related to a kind of vane of vertical shaft wind-driven generator.
Background technique
At present, vane of vertical shaft wind-driven generator mainly contains resistance type and lift-type, resistance type blade be utilize air stream to produce on blade resistance acting, there is larger torque and good startability, but tip speed ratio and wind energy transformation rate lower.Lift-type blade is the pressure difference acting utilizing air stream to produce on blade, has higher tip speed ratio and wind energy transformation rate, but torque little being difficult to starts.Disclosed in prior art, lift-type blade has mostly followed the design of aviation aerofoil profile and aircraft wing, and aircraft wing relative atmospheric is active body, and air is by kinetoplast, and the relative velocity of aircraft wing and air is higher in addition.The blade working system of wind-driven generator application is just in time contrary with the work system of aircraft wing, and namely air is active body, and blade is by kinetoplast, and the relative velocity of blade and air is lower.So the blade of aviation Airfoil Design is not well positioned to meet the requirement of wind-driven generator.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of and there is larger torque, the vane of vertical shaft wind-driven generator of higher tip speed ratio, wind energy transformation rate and good startability.
The technological scheme realizing above-mentioned purpose is: a kind of vane of vertical shaft wind-driven generator, and it is the perpendicular blade putting work, and the cross section of this blade is the asymmetric air-foil that outer side surface camber is greater than inner side surface camber; The upper and lower of described blade is straight blades section, the curved vane section of middle part for being convexly curved laterally, and the thickness of its curved vane section up and down by centre is successively decreased and to connect with described upper and lower straight blades section smooth transition in two ends, form that upper and lower is straight blades section, middle part is the straight of curved vane section and bending combined blade; Be provided with opening at the middle part of described blade and be positioned at choke chamber inside trailing edge.
Leading edge in the middle part of described blade and trailing edge are distinguished curved outwardly, form the blade not waiting width.
Described blade is arranged to hollow structure.
Agent structure of the present invention adopts asymmetric air-foil, can better adapt to air be active body, blade for by the work system of kinetoplast, the working environment of more effective reform of nature wind speed; Adopt straight and bending combined blade, blade is worked under different turning radius, better can adapt to the requirement of wind speed change; In the middle part of blade, in trailing edge, the choke chamber design of side opening makes blade tool drag characteristic, and be convenient to start, tool energy-storage function, effectively can avoid the stepping phenomenon of wind-driven generator simultaneously.
The present invention adopts design wide and bending laterally in the middle of blade, better can collect wind energy.
The present invention adopts hollow structure, is conducive to reducing the weight of blade and cost of production, reduces the rotation safety problem producing large inertia because of large quality and bring simultaneously.

Embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described.
As accompanying drawing, this vane of vertical shaft wind-driven generator is the perpendicular blade putting installment work, and this blade is the asymmetric air-foil that outer side surface camber is greater than inner side surface camber.Top 1 and the bottom 2 of this blade are straight blades section, middle part 3 is the curved vane section be convexly curved laterally, the thickness of its curved vane section up and down by centre is successively decreased and to connect with upper and lower straight blades section smooth transition in two ends, forms that upper and lower is straight blades section, middle part is the straight of curved vane section and bending combined blade.The middle part of blade is provided with choke chamber 4, and the opening in this choke chamber 4 is lip, and inside the trailing edge being positioned at blade, cavity is shunk to intrados transition gradually by opening, is triangular cavity roughly.
Leading edge in the middle part of this vane of vertical shaft wind-driven generator and trailing edge are distinguished curved outwardly, form the blade not waiting width.
Blade of the present invention is arranged to hollow structure.
