Description
Technical field
The utility model relates to technical field of wind power, especially a kind of resistance type 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 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 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.
In order to improve the generating efficiency of Savonius type wind wheel, domestic and international researcher improves on its basis, has occurred screw type Savonius wind wheel, combined wind wheel, has installed the New type of S avonius wind wheels such as the wind wheel of wind guiding mechanism.
Model utility content
The utility model provides a kind of resistance type wind wheel for vertical axis aerogenerator, and the basis of Savonius type wind wheel is improved, and adopts micro-S type blade that two opposing parallel, increases wind wheel blowing area, improves wind wheel generation efficiency.
The technical solution of the utility model:
For a resistance type wind wheel for vertical axis aerogenerator, comprise the upper and lower round pallet of two micro-S shape blades and stator blade.
Described two the parallel correspondences of micro-S shape blade are distributed on round pallet, and are centrosymmetric about the central shaft of wind wheel.
The outer plate surface of described upper and lower round pallet 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 micro-S shape blade and upper and lower round pallet are riveted.
Formation flanging is turned up at the edge of described upper and lower round pallet.
The utility model is compared with the Savonius type wind wheel before improving, and threshold wind velocity is lower, and wind energy transformation efficiency is high; The aluminium alloy plate thickness manufacturing semi-circle blade and blinker can be low to moderate 0.7mm, saves material, reduces fabricating cost.

Embodiment
The utility model is set forth further below in conjunction with accompanying drawing.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
The utility model is a kind of resistance type wind wheel for vertical axis aerogenerator, as shown in Figure 1, comprises upper round pallet 2, the lower round pallet 3 of two micro-S shape blades 1 and stator blade.
Described two the parallel correspondences of micro-S shape blade 1 are distributed on round pallet 2,3, and are centrosymmetric about the central shaft of wind wheel.
Described micro-S shape blade 1 is riveted with upper and lower round pallet 2,3.
Preferably, the edge of described upper round pallet 2 and lower round pallet 3 is turned up and is formed flanging 5, and the intensity of round pallet 2 and lower round pallet 3 self in reinforcement, prevents its deformed damaged when wind regime is larger.
Preferably, the upper plate surface of described upper round pallet 2 and the lower surface of lower round pallet 3 respectively have 4 stiffening ribs 4, and stiffening rib 4 uniform intervals emitting shape in the outer plate surface of round pallet is arranged, with reference to figure 1.When the aluminium alloy plate thickness that blade uses reduces, stiffening rib 4 is for strengthening the intensity of upper round pallet 2 and lower round pallet 3.
