Electrical efficiency.
Wind power generating set is generally mounted to high mountain and borderland region, and wind electricity blade surface often will appear icing phenomenon,
The performance and wind power generating set power output for leading to blade are unable to reach design requirement.Under cryogenic conditions, wind electricity blade table
Face icing has become the principal element of long-standing problem wind-power electricity generation winter normal operation.It will lead to wind-driven generator shutdown, reduce
The generated energy of generating set；And the shape and structure of wind electricity blade can be destroyed, lead to the reduction of blade wind-engaging ability；It will also result in hair
Motor service life reduction, etc. bad harm.
Existing clearing ice technology, including mechanical deicing and heating power deicing；But mechanical deicing is held by the way of manually beaing
It easily causes and generating set is damaged.Heating power deicing common use Resistant heating or surface indirect heating deicing etc.；
But heating power deicing is used, the device of use is bigger, and also bigger to the pressure of wind electricity blade, difficulty of construction is larger, power consumption
Amount is big, at high cost, seriously affects the ability and efficiency of wind-power electricity generation.
It would therefore be highly desirable to propose that a kind of anti-icing wind electricity blade improves wind-power electricity generation fundamentally to solve icing phenomenon
Efficiency.
Summary of the invention
In view of this, the present invention is directed to propose a kind of anti-icing wind electricity blade, to utilize hydrophobic coating layer and ultrasonic wave knot
It closes and carries out anti-icing processing, fundamentally solve icing phenomenon, improve the efficiency of wind-power electricity generation.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of anti-icing wind electricity blade, including blade body coat super-hydrophobic coat in the outer surface of blade body；It is described
Cavity is set in blade body, attaches ultrasonic transducer on cavity inner surface.
Further, ultrasonic transducer is attached on the cavity inner surface at the leading edge die parting line of blade body.
Further, the ultrasonic transducer is along being 0.5m to being on the length direction of 20-30m apart from blade tip apart from blade tip
It is uniformly arranged several.
Further, the ultrasonic transducer connects by the way that the cavity inner surface of ultrasonic wave conductive glue and blade body is fixed
It connects.
Further, blade body one end is connected with wheel hub, and several blade bodies are uniformly arranged on the wheel hub.
Further, the ultrasonic transducer is connected by cable with supersonic generator, and the supersonic generator is set
It is placed in hub cavity.
Further, the position that the super-hydrophobic coat corresponds to ultrasonic transducer is coated in blade body outer surface.
Further, the super-hydrophobic coat with a thickness of 0.3-0.5mm.
Compared with the existing technology, the anti-icing wind electricity blade of one kind of the present invention has the advantage that
Super-hydrophobic coat surface can extend freezing time, but after the capillary structure on water droplet wetting surface, still can produce
Raw the problem of freezing.Super-hydrophobic coat is coated in the outer surface of blade body, attaches ultrasonic waves in the cavity of blade body
Can device so that while liquid nonwetting super hydrophobic surface, promote oneself migration of drop by super-hydrophobic coat with ultrasonic wave ining conjunction with
And it is as much as possible merge, tumble, keep the hydrophobic property of super hydrophobic surface.And then fundamentally realize that blade body is anti-
The performance of icing.
