Description
Technical field
The utility model belongs to wind power generation field.Relate in particular to clockwork spring energy storage type wind power generation machine.
Technical background
Wind-power electricity generation is one of present clean energy resource of advocating energetically in the world and developing.Existing wind power plant is divided into small-sized and large-scale two kinds.Small-size wind power-generating equipment mainly is made of fans, generator, empennage, yaw system and inverter, unloader, battery pack etc.Large-scale wind generating equipment mainly is made of fans, speed increaser, generator, fan blade yaw system, electrical system, hydraulic system, inversion off-load and constant frequency constant speed regulating device etc.
Small-sized wind power equipment fans is fixed on the generator shaft, empennage and deflection mechanism are fixed on the generator housing, when being arranged, wind adjusts the windward side by the driftage empennage, make fan blade obtain corresponding rotational speed, drive generator for electricity generation, by cable after inversion and off-load, under pass and be stored in the storage battery, storage battery outputs in the load by inversion.
The fans of large-scale wind electricity is connected on the axle bed by bearing, and axle bed connects with the speed increaser input shaft.Each fans on axle bed by bearing rotation so that adjust the wind-exposuring area of fan blade according to wind speed, obtain balanced wind torsion, make the rotational speed of fan blade reach the using scope of generator by speed increaser.Speed increaser is the set of gears group, and its output terminal links to each other with generator, drives engine power generation.Electric and hydraulic system is the system that supports that fan blade deflection, driftage, inversion, off-load and horizontal constant speed are frequently adjusted.
