Abstract

The utility model discloses a high efficient aero-generator. Output shafts are respectively arranged on a stator and a rotor of the aero-generator and are respectively positioned at two ends; the output shafts at the two ends are respectively fixed on a bracket through two bearings; a slip ring is arranged on the output shaft which is arranged on the stator so as to lead out the generated electric current; wind wheels are respectively arranged on the output shafts at the two ends and rotate along the opposite direction respectively; a revolving body is arranged at the lower end of the bracket; a bearing rod and wind rudders are arranged on one side of the revolving body. When wind power blows to the aero-generator, the wind rudder leads the wind wheels to rotate windward, both the two wind wheels can absorb stronger wind energy because a certain distance exists between the front wind wheel and the rear wind wheel, thereby increasing the utilization ratio of the wind energy and increasing the generated energy; in addition, the structure is simple, the manufacturing cost is low, and the aero-generator is widely applied to various wind power generation circumstances.

Description

A kind of high-efficiency wind driven generator
Technical field
The utility model belongs to wind power generation field, especially a kind of high-efficiency wind driven generator.
Background technique
Wind-driven generator extensively uses in all parts of the world at present, and wind-driven generator is also varied.Column is arranged, horizontal wind direction is arranged, there is single blade that multiple-blade is also arranged, but from practical application, the generator of all various types of models is not ideal on generating efficiency and wind energy utilization at present, even adopt magnetic suspension also just to reduce mechanical resistance and surface friction drag, do not improve wind energy utilization well.And the two-directional rotation electric generator that has through consulting.Though can be rotor and stator despining mutually, because of two wind wheels with at one end, and abut against together mutually.Wait when rotated when the wind wheel of front like this and formed a wind loop, make the wind wheel of back can't absorb more energy again.Because two-wheeled reverses mutually together, two wind wheels are affected mutually again, thus the effect that can not bring into normal play, thus Wind Power Utilization efficient is reduced, generated energy reduces.Yet this structure makes again to superscribe a housing in the periphery of generator again, and then makes generator weight strengthen cost up.
Summary of the invention
In order to overcome the shortcoming that existing wind-driven generator Wind Power Utilization efficient is low, start wind speed height, structure heaviness, the utility model provides a kind of counter-rotating wind-driven generator of respectively establishing a wind wheel at the generator two ends, it utilizes aerodynamic principle, makes a kind of high-efficiency wind driven generator that Wind Power Utilization efficient improves, generated energy increases, the startup wind speed reduces.
The technological scheme that the utility model adopted is: respectively be provided with output shaft on the stator of generator and rotor, output shaft lays respectively at two ends, the output shaft at two ends respectively by two bearing fixing on support, on the output shaft of stator, be provided with slip ring, so that an electric current that produces is derived.And on the output shaft at two ends, respectively be provided with wind wheel, and be opposite direction rotation respectively.Lower end at support is provided with solid of rotation, and a side of solid of rotation has pole and wind rudder.When wind-force blew, the wind rudder facing the wind to rotate wind wheel, because of front wind wheel and back wind wheel at intervals, institute is so that two wind wheels can both absorb bigger wind energy, thus the raising wind energy utilization, the increase generated energy.
The beneficial effects of the utility model are, stator and epitrochanterian wind wheel can both absorb the energy of wind preferably, when low wind speed, can obtain than electric current greatly, and also simple in structure, cost of production is low, is widely used in various wind-power electricity generation occasions.
