Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: a fan blade composite coating anti-icing and deicing system comprises a blade 1, a hub 2, an engine room 3, an electric heating unit 4, a heating control cabinet 5 and an icing detector 6, wherein the hub 2 is arranged at the front end of the engine room 3, three blades 1 are uniformly distributed and fixed on the hub 2, the heating control cabinet 5 is arranged at the root of each blade 1, the electric heating unit 4 is also arranged inside each blade 1, and the icing detector 6 is arranged on the outer surface of each blade 1; the blade 1 is internally provided with an electric heating layer 7, and the blade is externally provided with an anti-icing coating 8.

And a temperature sensor is also embedded in the blade 1.
The working principle of the embodiment is as follows: firstly, the icing thickness of the blade is detected through an icing detector, after the icing thickness exceeds a certain limit value (a preset maximum ice layer thickness value), a heating control cabinet receives a starting instruction sent by an electric heating unit, the heating control cabinet starts an electric heating layer, meanwhile, a pre-embedded temperature sensor monitors the surface temperature of the blade, and when the temperature exceeds a certain safety threshold value, the electric heating is closed, and deicing is completed.
The fan anti-icing and deicing system structure of the embodiment is a multilayer heat conduction structure, and comprises an anti-icing coating, a skin, an electric heating layer, a heat insulation layer and the interior of a blade from outside to inside in sequence, as shown in fig. 2. The electric heating layer transfers the generated heat to the surface of the blade, the surface of the blade is rapidly heated, a melted water film is formed between the surface of the blade and the ice layer, and the ice can naturally fall off under the action of natural wind, blade vibration and the like by utilizing the micro-nano structure of the coating. The coating can play a role in reducing the adhesive force of ice, delaying the icing time, inhibiting the transfer of the ice and the like. Traditional single electric heat coating need form thicker water film just can drop ice at ice and blade interface, and utilizes anti-icing coating and electric heating layer combination mode, forms very thin water film between the interface, reduces the adhesive force of ice, makes ice drop very easily, and the electric heat energy consumption can reduce by a wide margin. The heat insulation layer is made of a material with a small heat conductivity coefficient and a small specific heat capacity, and heat is blocked from being transferred to the interior of the blade to the maximum extent.
