Description
Technical field
The utility model relates to technical field of wind power, especially a kind of combined wind wheel for vertical axis aerogenerator.
Background technique
The wind driven generators of main flow is horizontal axis wind-driven generator in the market, and its advantage is that tip speed ratio is comparatively large, and wind speed round is fast, and generating efficiency is high; Its shortcoming is, internal structure is complicated, transport and installation cost higher, and noise pollution is large.On the contrary, vertical shaft wind power generator structure is simple, with low cost, but because the tip speed ratio of original vertical axis aerogenerator is very little, wind energy utilization is on the low side, vertical axis aerogenerator is not taken seriously always, until 20th century Savonius formula wind wheel and the appearance of Darrieus formula wind wheel.
Savonius formula wind wheel is resistance type wind wheel, and advantage is that detent torque is large, almost can self-starting under any wind speed, and electric energy conversion equipment is simple, can be arranged on the surface of building; Shortcoming is that blade nonsymmetry causes air-flow to produce lateral thrust to wind wheel, causes too much loss, affects generating efficiency and Security.
Darrieus formula wind wheel is lifting wind wheel, shortcoming is self-starting poor performance, needs external force to provide detent torque to be dragged by wind wheel and rotates to certain rotating speed, make the lift of blade surface can provide moment of rotation completely, under lift effect, drive electrical generators rotary electrification.Although Darrieus lifting wind wheel difficulty in starting, once run, rotating speed will far away higher than Savonius resistance type wind wheel, and overall wind energy utilization is higher.
Model utility content
For solving the problem, the utility model provides a kind of combined wind wheel for vertical axis aerogenerator, adopt Savonius resistance type wind wheel in conjunction with Darrieus lifting wind wheel, and improve on the basis of Savonius formula wind wheel, root of blade is not connected, and is convenient to air flowing, set up wind wheel blinker, change the flow direction of wind field, increase the blowing area of wind wheel, thus improve the generating efficiency improving rear wind wheel on the whole.
The technical solution of the utility model:
For a combined wind wheel for vertical axis aerogenerator, Savonius formula wind wheel and Darrieus formula wind wheel are combined.
Described Savonius formula wind wheel comprises the upper and lower round pallet of three semi-circle blades, three blinkers and fixing semi-circle blade and blinker, three semi-circle blades are evenly distributed on round pallet, be mutually 120 ° of angles, the center line of the more than half curved blade of blinker and perpendicular to semi-circle blade, blinker while coplanar with the both sides of semi-circle blade, another side stretches out.
The outer plate surface of the described upper and lower round pallet of Savonius formula wind wheel respectively has 4 stiffening ribs, and stiffening rib uniform intervals emitting shape in the outer plate surface of round pallet is arranged, mutual angle in 90 °;
Described Savonius formula wind wheel semi-circle blade, blinker and upper and lower round pallet are riveted;
Formation flanging is turned up at the edge of the described upper and lower round pallet of Savonius formula wind wheel.
Described Darrieus formula wind wheel is Darrieus formula φ type wind wheel, comprise the arc plate of three, described arc plate comprises the circular arc part being positioned at stage casing and the line part being positioned at circular arc part two ends, and two line part external end heads of arc plate are fixedly connected on the main shaft of wind-driven generator respectively;
Described Darrieus formula wind wheel arc plate is alloy plastic parts, inside establishes glass fibre mesosphere.
The utility model is in view of Savonius formula wind wheel and Darrieus formula wind wheel pluses and minuses separately, the low wind speed of Savonius formula wind wheel easily starts but generating efficiency is low, high but the low wind speed difficulty in starting of Darrieus formula wind wheel generation efficiency, Savonius formula wind wheel and Darrieus formula wind wheel are combined, give full play to the advantage of two class wind wheels, and improve on the basis of Savonius formula wind wheel, root of blade is not connected, be convenient to air flowing, set up wind wheel blinker, change the flow direction of wind field, increase the blowing area of wind wheel, thus improve the generating efficiency improving rear wind wheel on the whole.
