Referring to fig. 1 to 3, the following technical solutions are adopted in the present embodiment: the utility model provides a blade coating and ultrasonic wave jointly anti-icing deicing system, includes anti-icing coating 1 and ultrasonic transducer 2, and wind turbine generator system blade leading edge middle part is provided with ultrasonic transducer 2, and the both sides of wind turbine generator system blade leading edge are anti-icing coating 1, and wind turbine generator system blade trailing edge is whole to be anti-icing coating 1, ultrasonic transducer 2 adopt piezoceramics.
And the gap between the ultrasonic transducers 2 is also provided with an anti-icing coating 1.
The distribution rule of the ultrasonic transducers 2 is as follows: and a large number of ultrasonic transducers are arranged in the severe ice-coated area of the front edge of the blade tip, and a small number of ultrasonic transducers are arranged in the secondary severe ice-coated areas of the root part and the front edge part of the blade tip.
The anti-icing coating 1 adopts a core-shell structure polymer emulsion anti-icing system.
The blade coating and ultrasonic wave combined anti-icing and deicing system comprises the following processes: under the extreme icing condition, icing thickness is monitored in real time by using an icing detection sensor, when the icing thickness exceeds a certain threshold value, an icing detection system issues a starting deicing signal to an ultrasonic PLC (programmable logic controller), an ultrasonic generator controls piezoelectric ceramics on the surface of the blade to start oscillation, high-frequency ultrasonic waves on the surface of the blade cause oscillation of a solid medium, shearing force is generated on an interface, the coating is combined to reduce the ice adhesion strength, the power consumption of an ultrasonic transducer can be greatly reduced, and the deicing efficiency is improved.
The coating-assisted ultrasonic combined deicing system of the present embodiment includes an anti-icing coating and an ultrasonic deicing device. The front edge of the blade of the wind turbine generator is seriously coated with ice, and the ice coating amount from the blade tip to the front edge of the middle section of the blade is increased gradually, so that the front edge is deiced in a mode of combining ultrasonic waves and a coating, and the secondary serious ice coating area at the rear edge is deiced in an ultralow ice adhesion coating mode.
The distribution rule of the ultrasonic transducer of the embodiment is as follows: a large number of ultrasonic transducers are arranged in the severe ice-covered area of the front edge of the blade tip, and a small number of ultrasonic transducers are arranged in the secondary severe ice-covered area of the root part and the front edge part of the blade tip, so that the deicing efficiency can be improved to the greatest extent, and the cost can be reduced. The blank area between two adjacent groups of ultrasonic transducers at the front edge of the blade is also coated with the ultra-low ice adhesion coating.

The light and medium icing condition mainly depends on coating anti-icing, and the coating and ultrasonic wave combined deicing technology is adopted for the serious icing condition. The anti-icing coating adopts a core-shell structure polymer emulsion anti-icing system, and before icing, air retained in a micro-nano structure on the surface of the coating is utilized to promote the rebound of water drops and the merging of condensed water drops to cause self-movement so as to prevent the icing. When icing occurs, hydrophilic groups contained in the hydrophilic shell in the coating micro-nano structure can further absorb water, and then an extremely thin layer of aqueous solution is formed, and the aqueous solution has a low freezing point, so that a non-icing water film is formed on the surface of the coating, and the ice layer on the surface of the blade can be removed under low shearing force.
The specific embodiment is a coating and ultrasonic combined anti-icing and deicing system, ultrasonic generated by piezoelectric ceramics causes high-frequency oscillation of a solid medium, a strong shearing force is generated on a joint surface of the blade surface and an ice layer, so that the ice layer generates micro cracks and a thin water film, and meanwhile, the coating with ultralow ice adhesion greatly reduces the adhesion strength of the blade surface and ice, so that the ice layer is easily removed under the combined action of natural wind power, blade vibration and ultrasonic. The deicing system has the advantages of low energy consumption, high deicing efficiency, good stability and wide application range, and can solve the difficult problems of light, medium and repeated icing.
