Description

Wind generating unit
Technical field
The utility model relates to a kind of wind generating unit that utilizes wind energy power.
Background technique
Wind energy is a kind of cleaning and the reproducible energy, utilizes wind energy to generate electricity, and has become one of approach of alleviating present world energy sources short supply state.
Be located at the lighting burner on outdoor location (as road, square etc.) at present, especially street lamp all is by the special electric power line powering basically, expends a large amount of electric energy during illumination, causes white elephant to electrical network.
For the burden that the lighting burner that reduces outdoor location causes to electrical network, people have designed some can be installed in the wind generating unit of outdoor location, utilizes wind energy to generate electricity, and provides electric energy for lighting burner.
For example, existing a kind of lamppost, lamppost is provided with generator and flabellum, flabellum is installed on lamppost upper end and is in transmission connection with the rotor of generator, and flabellum rotates under wind action, and drives the rotor rotation of generator, wind energy is converted to electric energy, uses for the lighting burner on the lamppost.This lamppost utilizes natural wind to generate electricity, because the wind direction and the wind speed of natural wind all constantly change, so the generated energy instability, when wind-force is less or calm, even do not generate electricity, and utilization ratio of wind energy is not high.In addition, because flabellum is installed on the lamppost upper end, when lamppost used as street lamp, the flabellum of rotation can disturb driver's sight line, may cause traffic accident.
And for example, a kind of wind-driven generator of Chinese utility model patent specification CN2911235Y number bulletin comprises the light pole and the electricity generating device of casing, hollow; The light pole of hollow is installed on the casing, with the exhaust outlet formation high stack effect passage of casing; Casing has collection wind angle along the both sides of wagon flow direction; Electricity generating device is positioned at casing, and electricity generating device comprises external rotor, inner stator and vane group (being flabellum), and vane group is installed on the external rotor.Wherein the high stack effect passage is an air-flow path of trend up and down, is made of the hollow space of light pole, and the air flow inlet of this air-flow path promptly is the exhaust outlet of casing, that is to say, vane group is in the below of this air-flow path air flow inlet.Air-flow flows after entering casing from collection wind angle obliquely upward, and drives the vane group rotation, enters air-flow path in the light pole through the exhaust outlet of casing then, and the flow outlet from the air-flow path upper end flows out at last.Because the air-flow in the casing flows obliquely upward, therefore there is sizable a part of wind energy not caught by vane group, utilization ratio of wind energy is not high, and generated energy is less.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can make full use of the wind generating unit that the upward flow that produced by high stack effect generates electricity.The technological scheme that adopts is as follows:
A kind of wind generating unit comprises generator, and generator comprises stator and rotor, it is characterized in that: described wind generating unit also comprises a bearing, be provided with the air-flow path of trend up and down in the bearing, be provided with flabellum in the air-flow path, the rotor of flabellum and generator is in transmission connection.
