Abstract
The invention relates to a drag type wind wheel for a vertical-axis wind-driven generator and relates to the technical field of wind power generation. The drag type wind wheel comprises two slightly S-shaped blades and upper and lower round carrier plated for fixing the blades. The two slightly S-shaped blades are distributed on the round carrier plates correspondingly in parallel and form central symmetry with respect to the central axis of the wind wheel. The outer plate surface of each of the upper and lower round carrier plates is provided with four reinforcing ribs which form an included angle of 90 degrees with one another; the slightly S-shaped blades are riveted to the upper and lower round carrier plates; the edges of the upper and lower round carrier plates are folded to form folded edges. Compared with the conventional Savonius wind wheel, the drag type wind wheel has the advantages of lower start wind speed and high wind energy conversion efficiency; the thickness of aluminum alloy plates used for making the semi-circular arc blades and wind stop sheets can be reduced to 0.7mm, so that materials are saved and the making cost is reduced.
Description
Technical field
The present invention relates to technical field of wind power, a kind of resistance-type 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 type wind wheel and the appearance of Darrieus type wind wheel.
Savonius type 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.
In order to improve the generating efficiency of Savonius type wind wheel, domestic and international research worker improves on its basis, occurs in that screw type Savonius wind wheel, combined wind wheel, installs the novel Savonius wind wheel such as wind wheel of wind guiding mechanism.
Summary of the invention
The present invention provides a kind of resistance-type wind wheel for vertical axis aerogenerator, is improved on the basis of Savonius type wind wheel, uses two opposing parallel micro-S type blades, increases wind wheel wind area, improves wind wheel generation efficiency.
Technical scheme:
A kind of resistance-type wind wheel for vertical axis aerogenerator, including two micro-S-shaped blades and the upper and lower round pallet of fixing blade.
Two described micro-parallel correspondences of S-shaped blade are distributed on round pallet, and the central shaft about wind wheel is centrosymmetric.
The outer plate surface of described upper and lower round pallet 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 micro-S-shaped blade rivets with upper and lower round pallet.
Formation flanging is turned up at the edge of described upper and lower round pallet.
The present invention is compared with the Savonius type wind wheel before improvement, and threshold wind velocity is lower, and wind energy transformation efficiency is high；Manufacture semi arch blade and blinker aluminium alloy plate thickness can as little as 0.7mm, save material, reduce cost of manufacture.

Detailed description of the invention
The present invention is expanded on further below in conjunction with the accompanying drawings.Should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
The present invention is a kind of resistance-type wind wheel for vertical axis aerogenerator, as it is shown in figure 1, include two micro-S-shaped blades 1 and the upper round pallet 2 of fixing blade, lower round pallet 3.
Two described micro-parallel correspondences of S-shaped blade 1 are distributed on round pallet 2,3, and the central shaft about wind wheel is centrosymmetric.
Described micro-S-shaped blade 1 rivets with upper and lower round pallet 2,3.
Preferably, formation flanging 5 is turned up at the edge of described upper round pallet 2 and lower round pallet 3, and in reinforcement, round pallet 2 and the intensity of lower round pallet 3 self, prevent its deformed damaged when wind regime is bigger.
Preferably, the upper face of described upper round pallet 2 and the lower surface of lower round pallet 3 are respectively arranged with 4 reinforcements 4, and reinforcement 4 uniform intervals emitting shape in the outer plate surface of round pallet is arranged, with reference to Fig. 1.When the aluminium alloy plate thickness that blade uses reduces, reinforcement 4 is for strengthening upper round pallet 2 and the intensity of lower round pallet 3.
