Abstract
The utility model discloses a vertical type dual-rotor wind driven generator which comprises an inner rotor, wherein the inner rotor is externally and coaxially sheathed with an outer rotor, the periphery of the shell of the outer rotor is connected with a first wind wheel, one end of an inner rotor shaft is extended out of the shell of the outer rotor to be connected with a second wind wheel, and the rotation direction of the blades of the first wind wheel and the rotation direction of the blades of the second wind wheel are in opposite direction; and the inner rotor shaft is in a hollow structure, and a support shaft penetrates through the inner rotor shaft to be connected with a bracket. The vertical type dual-rotor wind driven generator with the structure respectively drives the inner rotor and the outer rotor to rotate in opposite directions by the two wind wheels with opposite rotation directions, and any transmission relationship between the inner rotor and the outer rotor is unavailable, so that the running resistance of the wind driven generator is low and the wind conversion efficiency is high. The structure is simple, and a support structure that the supporting shaft penetrates through the inner rotor shaft is adopted, so that the wind driven generator can be placed horizontally, the application range of the wind power generation can be greatly increased, and the vertical type dual-rotor wind driven generator can be arranged at the places such as the top of a vehicle and the top of a factory.
Description
Technical field
The utility model belongs to wind generating unit, a kind of dual-rotor wind power generation machine of specific design.
Background technique
Present wind-power electricity generation all is the large-scale wind power plants that are provided with in large-scale wind field.And for small-sized wind power plant as on vehicle, using, the small-size wind power-generating equipment that family uses will have higher transformation efficiency with regard to requiring small-sized wind-driven generator because air quantity is limited.And existing small-sized wind-driven generator is the single rotor generator mostly, and efficient is relatively low.The supporting structure complexity of the structure relative complex, particularly two-way rotation of existing dual-rotor wind power generation machine causes conversion ratio lower equally.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical double-rotor wind-driven generator simple in structure, to address the above problem.
The technical solution of the utility model is: the vertical double-rotor wind-driven generator, it comprises internal rotor, the outer coaxial sheathed external rotor of internal rotor, connect first wind wheel on the outer rotor case circumference, inner rotor shaft one end stretches out outer rotor case and is connected with second wind wheel, and the blade rotation direction of first wind wheel and second wind wheel is opposite; Inner rotor shaft is a hollow structure, and supporting axle passes inner rotor shaft and is connected with support.
Establish the permanent magnetism yoke on the described internal rotor, what establish on the external rotor is coil.
Described outer rotor case end face is provided with the hole, the electric energy lighting outlet of coil pass the hole and in sealing, electroconductive elastic sheet or ball are established in the electric energy lighting outlet end of coil, supporting axle is provided with insulation disk, insulation disk is provided with conductive hoop, conductive hoop contacts with electroconductive elastic sheet or ball, and conductive hoop is connected with the outer lighting outlet of electric energy.
Be provided with bearing between the end face of described inner rotor shaft and rotor housing, be provided with bearing between inner rotor shaft and the supporting axle.
The vertical double-rotor wind-driven generator of said structure, it utilizes the opposite wind wheel that is provided with of two rotation directions to drive the opposite direction rotation of inside and outside two rotors peace respectively, and between inside and outside two rotors without any drive connection, the resistance of generator operation is low like this, wind power transformation is renderd a service high.It is simple in structure, and it is little to take up room.Adopt supporting axle to pass the supporting structure of inner rotor shaft, can realize the vertical placement of generator, can increase the Applicable scope of wind-power electricity generation greatly, it can be installed in the top of vehicle, occasions such as the top of factory building.
