Abstract

The utility model discloses an aero-generator with double wind wheels. A rotor spindle is arranged on a rotor of the aero-generator; the rotor spindle extends out two ends of a stator of an electric motor respectively; the wind wheels are respectively arranged at the two ends of the rotor spindle; a revolving body is connected under the stator; an upright post is arranged under the revolving body; a wind rudder is 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 fully absorb the 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; more particularly, the wind wheels can be led to rotate for power generation only by weak wind when the wind power is weak.

Description

A kind of double-wind-wheel wind power generation machine

Technical field

The utility model belongs to wind power generation field, especially a kind of double-wind-wheel wind power generation machine.

Background technique

At present, wind-driven generator extensively uses in all parts of the world, and wind-driven generator is also varied.Vertical shaft arranged, horizontal wind direction is arranged, have single blade 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 Power Utilization efficient at present, and particularly existing wind-driven generator starts the wind speed height, and Wind Power Utilization efficient is low.

Summary of the invention

Start wind speed height, the inefficient drawback of Wind Power Utilization in order to overcome existing wind-driven generator, the utility model provides a kind of Wind Power Utilization efficient height, starts the low double-wind-wheel wind power generation machine of wind speed.

The technological scheme that the utility model adopted is: be provided with rotor shaft on the rotor of generator, rotor shaft stretches out the motor stator two ends respectively, is separately installed with wind wheel on the rotor shaft two ends, is connected with solid of rotation below stator, there is column solid of rotation below, is provided with the wind rudder in a side of solid of rotation.When wind-force blows, the wind rudder facings the wind wind wheel and rotates, because of front wind wheel and back wind wheel at intervals, so can make two wind wheels can both fully absorb the energy of wind, thereby raising wind energy utilization, increase generated energy,, just can make wind wheel rotate generating even particularly at the less small wind of wind-force.

Embodiment

Below in conjunction with description of drawings, the utility model is further elaborated.

As Fig. 1, Fig. 2, rotor 2 is housed in the stator 1, rotor 2 is provided with rotor shaft 3, rotor shaft 3 is respectively by bearings at both ends 4 supports, and rotor shaft 3 stretches out the two ends of generator unit stator 1 respectively, is separately installed with wind wheel 5 at the two ends of rotor shaft 3, air guide sleeve 6 is arranged before the wind wheel 5, be provided with solid of rotation 7 in the lower end of stator 1, a side of solid of rotation 7 then is provided with wind rudder 8, and column 9 also is equipped with in the below of solid of rotation 7.When wind came, wind wheel 4 drove rotor shaft 3 and rotates simultaneously, sent electric current thereby make more weak wind just can drive the rotor rotation.The utlity model has Wind Power Utilization efficient height, start low, the advantage such as operate steadily of wind speed, especially under the lower situation of wind speed, get final product rotary electrification, is that conventional electric generators is incomparable.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
