Abstract
The invention relates to a combined type wind wheel for a vertical axis wind turbine. The wind wheel is formed by combining a Savonius wind wheel and a Darrieus wind wheel. The Savonius wind wheel includes three semi-circular arc blades, three wind stop sheets and upper and lower round carrier plates used for fixing the semi-circular arc blades and the wind stop sheets; the three semi-circular arc blades are uniformly distributed on the round carrier plates and form included angles of 120 degrees in pairs. The Darrieus wind wheel is a Darrieus phi-type wind wheel and comprises three arc-shaped plates, wherein each arc-shaped plate comprises a circular arc part in the middle section and straight line parts on the two ends of the circular arc part. The combined type wind wheel fully exploits the advantages of the two wind wheels; improvement is made on the basis of a Savonius wind wheel that the roots of the blades are not connected to facilitate air flow and wind wheel wind stop sheets are additionally arranged to change the flow direction of a wind field; thus the wind area of the wind wheel is increased and the power generating efficiency of the improved wind wheel is increased wholly.

Technical field
The present invention relates to technical field of wind power, a kind of combined wind wheel for vertical axis aerogenerator.
Background technology
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 relatively big, and wind speed round is fast, and generating efficiency is high；It is disadvantageously, internal structure is complicated, and transport and installation cost are higher, and noise pollution is big.On the contrary, vertical shaft wind power generator structure is simple, with low cost, but owing to the tip speed ratio of original vertical axis aerogenerator is the least, 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 big, almost can self-starting under any wind speed, electric energy converting apparatus is simple, it is possible to be arranged on the surface of building；Shortcoming is that blade unsymmetry causes air-flow that wind wheel is produced lateral thrust, causes too much loss, affects generating efficiency and safety.
Darrieus formula wind wheel is lifting wind wheel, and 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, makes the lift of blade surface be fully able to provide rotating torque, under lift effect, drive electromotor rotary electrification.Though Darrieus lifting wind wheel difficulty in starting, once run, rotating speed Savonius to be significantly larger than resistance-type wind wheel, and overall wind energy utilization is higher.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of combined wind wheel for vertical axis aerogenerator, Savonius resistance-type wind wheel is used to combine Darrieus lifting wind wheel, and improved on the basis of Savonius formula wind wheel, root of blade is not attached to, it is simple to air flows, set up wind wheel blinker, change the flow direction of wind field, the wind area of increase wind wheel, thus the generating efficiency of wind wheel after raising improves on the whole.
Technical scheme:
A kind of combined wind wheel for vertical axis aerogenerator, combines Savonius formula wind wheel and Darrieus formula wind wheel.
Described Savonius formula wind wheel includes three semi arch blades, three blinkers and fixing semi arch blade and the upper and lower round pallet of blinker, three semi arch blades are evenly distributed on round pallet, it is mutually 120 ° of angles, the centrage of the more than half curved blade of blinker and be perpendicular to semi arch blade, blinker while coplanar with the both sides of semi arch blade, another side stretches out.
The outer plate surface of the described Savonius upper and lower round pallet of formula wind wheel is respectively arranged with 4 reinforcements, and reinforcement uniform intervals emitting shape in the outer plate surface of round pallet is arranged, mutual angle in 90 °；
Described Savonius formula wind wheel semi arch blade, blinker rivet with upper and lower round pallet；
Formation flanging is turned up at the edge of the described Savonius upper and lower round pallet of formula wind wheel.
Described Darrieus formula wind wheel is Darrieus formula φ type wind wheel, including the arc of three, described arc includes the arc sections being positioned at stage casing and is positioned at the line part at arc sections two ends, and two line part external end heads of arc are respectively fixedly connected with on the main shaft of wind-driven generator；
Described Darrieus formula wind wheel arc is alloy plastic parts, inside sets glass fibre intermediate layer.
The present invention is in view of Savonius formula wind wheel and the respective pluses and minuses of Darrieus formula wind wheel, the low wind speed of Savonius formula wind wheel easily starts but generating efficiency is low, Darrieus formula wind wheel generation efficiency is high but low wind speed difficulty in starting, Savonius formula wind wheel and Darrieus formula wind wheel are combined, the advantage giving full play to two class wind wheels, and improved on the basis of Savonius formula wind wheel, root of blade is not attached to, it is easy to air flowing, set up wind wheel blinker, change the flow direction of wind field, increase the wind area of wind wheel, thus the generating efficiency of wind wheel after improving improvement on the whole.
