Description
Technical field
The utility model relates to a kind of wind-driven generator, belongs to technical field of wind power generation.
Background technique
Along with the growth of economy and population, electric power resource problem becomes more and more concerned social concern.Along with the intensification gradually of exploitation of coal resources, coal resources are increasingly deficient, meanwhile the haze problem brought of coal fired power generation, inspired entire society to go to consider that rational use of energy solves electric power resource problem.
Wind-force enters into the visual field of people gradually, and the energy that wind-force is contained is big, if can rationally, effectively utilize, so will effectively solve the problem of coal fired power generation scarcity of resources existing at present, environmental pollution.Calculate according to data, if effectively wind-force can be utilized, so electric energy of obtaining of the annual coal combustion in the whole world, only have wind-force in 1 year 1/3rd of electric energy is provided.
At present, wind-power electricity generation has become a kind of without the need to fuel, clean, effective generation mode, it takes full advantage of large, renewable, the free of contamination characteristic of wind energy potential, by the kinetic energy of wind is become mechanical kinetic energy, again changes mechanical energy is electric power kinetic energy thus generating.When generating electricity, required device is called wind power generating set, is generally made up of wind wheel (midget plant also comprises tail vane), wind-driven generator and steel tower three part.Wherein, wind wheel is the important feature part of mechanical energy by the kinetic energy of wind, and large by intensity, lightweight propeller blade wheel forms.The constant rotational speed obtained by wind wheel is then transformed mechanical energy into electricity by raising speed transmission by wind-driven generator.Steel tower is the structural member of wind-wheel supporting (and tail vane) and generator, and in order to obtain more greatly, comparatively evenly, have the wind-force of sufficient intensity, the construction height of steel tower needs to determine the impact of wind speed according to ground obstacle.During work, when wind is to impeller, impeller producing aerodynamic force drives wind wheel to rotate, because the rotating ratio of wind wheel is lower, and the size and Orientation of wind-force is in the state of constantly change, this just causes wheel speed unstable, the rated speed requirement of wind-driven generator cannot be met, so before utilizing wind wheel drive electrical generators, also must add the speed-changing gear box that is brought up to rotating speed generator rated speed, adding a speed regulating mechanism again makes rotating speed keep stable, and then is connected on generator.
As the vitals in wind power generating set, the quality of wind-driven generator decides the success or failure of wind-power electricity generation.From structure, wind-driven generator comprises cabin, rotor, stator, rotor blade, axle center, lower velocity shaft, gear-box, generator etc.During installation, all that stator is closely nested in engine room inside to arrange, but because stator and cabin are closely nested, the setting and stators and rotators cooperatively interacts, stator can be caused to produce vibration to a certain extent due to huge wind speed disturbance during rotor turns, thus be unfavorable for the tight nested setting of stator at engine room inside.In addition, wind-driven generator is when arranging, because the rotation etc. of inner rotator can produce larger heat, certain level is remained in order to realize cabin interior temperatures, generally all need to arrange fan to lower the temperature, and the setting position of fan is typically chosen in the end caps in cabin, the fan being positioned at end caps only can have certain temperature for the heat radiation at rotor place to a certain extent, but then cannot effectively control for the heat radiation of the gear-box far away apart from end caps and generator.
In addition, existing wind-driven generator shell mainly considers the performances such as its rigidity, but does not have too many consideration for the function of its heat radiation, even if be provided with heat-dissipating part such as fan etc., also little for wind-driven generator work thermolysis itself.
