Description
Technical field
Blower fan technical field is the utility model is related to, more particularly, to a kind of fan for air cooler of wind power generating set.
Background technology
Incrementally increased with the power of wind power generating set, original gravity-flow ventilation type of cooling cools down to generator
Cooling can not be effectively accomplished to require, the generator of powerful wind power generating set needs to carry out by force using air cooler substantially
But, blower fan is the important component in air cooler to refrigeration.In the season of cold, outdoor environment temperature is relatively low, does not start air cooling blower fan,
Only enter the cold wind flowed naturally of air duct with the air inlet through air cooling blower fan, it is possible to air cooling condenser radiating fin
Exhaust steam in tube bank condenses out.If the temperature of environment further reduces, air duct is entered certainly by the air inlet of air cooling blower fan
The cold wind so flowed can cause the exhaust steam and condensed water frosting and icing in radiating fin tube bank, air cooling condenser radiating fin
Exhaust steam and condensed water frosting and icing in piece tube bank, the flowing of condensate normal circulation is severely impacted or destroys, not only shadow
Unit normal operation is rung, can also cause the air cooling condenser bursting by freezing damage of costliness.Cause to enter sky in unit load change
The steam amount of air cooling condenser is very few or when variation of ambient temperature scope is larger, the tube bank of air cooling condenser radiating fin
Interior exhaust steam state is more big changes.Nighttime ambient temperature is too low or when steam amount is very few, the above-mentioned cold air flowed naturally
It will also result in the exhaust steam and condensed water frosting and icing in cooling condenser.In above-mentioned cold season or nighttime ambient temperature mistake
, it is necessary to which the method that air cooling condenser cold wind is blown over reduction nature flowing avoids air from cooling down when low and steam amount is very few
Exhaust steam and condensed water frosting and icing in condenser.In the prior art, air cooling condenser radiating fin tube bank lower section
Air cooling blower fan air inlet be it is unlimited, it is too low in the season of cold or nighttime ambient temperature and when steam amount is very few, it is this
Air cooling blower fan is not avoided that the cold wind that the air inlet through air cooling blower fan flows naturally causes condensed water frosting in radiating fin tube bank
And icing, therefore be badly in need of providing a kind of simple and reasonable, fan for air cooler of good freezing protection effect.

Horizontal direction walking support arm is provided with, described jack includes accommodating chamber and mobile holder, described mobile holder
One end is connected with walking support arm, and the other end of described mobile holder is connected with rotational support arm, described rotational support arm
It is connected with the output shaft of rotary electric machine, described rotary electric machine sets the bottom with defroster, is stored in described accommodating chamber
There is curtain, described curtain is connected with mobile holder, as mobile curtain of the mobile holder on guide rail can carry out folding and unfolding.
Retracting motor is provided with described accommodating chamber.
Described air inlet is provided with temperature sensor.
Described temperature sensor is connected with control system.
Described control system is connected with rotary electric machine and retracting motor.
Described curtain can cover whole air inlet when decontroling, and can be received into receiving when described curtain is packed up completely
In chamber.
Utility model has following beneficial effect：
(1) by the setting of defroster, it can prevent cold wind from entering air cooling blower fan, be effectively prevented the cold of condensed water
But and freeze；
(2) combination of jack, guide rail, road wheel, walking support arm and rotary electric machine so that conjunction simple in construction
Reason, automaticity is high, and the stability of device gets a promotion；
(3) by the setting of control system, itself and rotary electric machine and the organic cooperation of retracting motor are made so that antifreeze stabilization
Property lifting, the automaticity of device further improves.
