Abstract

The utility model discloses a double-impeller direct-driven type wind power generator which changes the single-impeller driven mode of the conventional fan, and improves the utilization rate of wind energy by matching of two impellers with certain taper angles and reusing wake flow; the double-impeller direct-driven type wind power generator comprises the two impellers, two rotors, an electric brush, a collecting ring and a bearing, and is characterized in that the two impellers are arranged at front and back and are respectively used for driving the two rotors to rotate in the opposite directions; and the power generator is divided into three layers of structures and can output direct current (DC) by matching of the electric brush and the collecting ring. The double-impeller direct-driven type wind power generator has the beneficial effects that the utilization rate of the wind energy is improved, the utilization space of the wind energy is enlarged, the internal structure of the wind power generator is simplified, the cost is low, the miniaturization and diversification development of the fan can be facilitated, and the wind energy is promoted to be effectively and widely utilized.

Description

A kind of bilobed wheel direct-drive aerogenerator
Technical field
The utility model relates to a kind of wind-driven generator that can improve wind energy utilization, especially can generate electricity under low wind speed.
Background technique
At present, widely used wind-driven generator is generally the variable pitch type constant speed wind-driven generator, it is the invariablenes turning speed of impeller, need to there be the complicated pitch-controlled system of a cover and thick and heavy gear-box to realize, not only the complex structure cost is high, and being only applicable to generating in certain wind speed interval, wind energy utilization is lower.On the other hand, present blower fan mostly is single impeller and drives, and the utilization ratio that single-stage drives wind energy not only is low, and has relatively high expectations for the structural strength of blower fan integral body.Above-mentioned some all be unfavorable for the extensive utilization of this clean energy resource of wind energy.
Summary of the invention
Low in order to solve the wind energy utilization that present blower fan exists, utilize the wind speed interval little, the shortcoming that the complex structure cost is high, the utility model provides a kind of bilobed wheel direct-drive aerogenerator, by bilobed wheel, the utilization again of wind energy has been improved wind energy utilization, directly driving type has increased wind speed and has utilized the interval, and has reduced the complexity of mechanism.
The technological scheme that its technical problem that solves the utility model adopts is: change the pattern that traditional wind-driven generator single impeller drives, use tandem two impellers with certain cone angle to drive two rotors.The wake flow of surface impeller before impeller has certain cone angle that the impeller of back is better utilized; The sense of rotation of impeller is identical, and one of them impeller commutates by gear tumbler, makes rotor 1 and rotor 2 do opposite the relatively rotating of sense of rotation.Rotor 1 is armature circuit, is formed by coil winding, and two end points of coil are connected with two brushes respectively; Rotor 2 provides permanent-magnetic field, is fixed into the shape of annulus by permanent magnet, and two semicircular collector rings coordinate with brush on rotor 1, convert Ac to direct current, and two collector rings connect respectively two brushes simultaneously; Shell plays the protection supporting function, connects simultaneously two collector rings in shell, coordinates with brush on rotor 2 respectively, and direct current is exported.
The beneficial effects of the utility model are, have improved wind energy utilization, have increased the Wind Power Utilization space, have simplified the internal structure of wind-driven generator, and cost is low, has advanced effectively extensively utilizing of wind energy.
