The invention discloses a deicing device and an unmanned aerial vehicle. A flexible heater and a capacitive sensor are mounted on the surface of each wing, and a super-hydrophobic coating is sprayed on the surface of each wing; based on the fact that the dielectric constants of ice and water are different, and the dielectric constants change along with temperature, when the wing is iced, the dielectric constant of a capacitor is changed, the capacitance of the capacitor is changed, the capacitance sensor transmits a change signal to a controller, and the controller controls the working state of the flexible heater according to the capacitance, so that deicing of the wing is realized. In addition, the super-hydrophobic coating can enable supercooled water drops to directly roll down after impacting the surface of the wing, and the supercooled water drops cannot be solidified and frozen after adhering to the surface of the wing; meanwhile, the super-hydrophobic coating can prevent backflow icing, that is, the super-hydrophobic coating can enable water generated after icing and melting of the front edge of the wing to directly roll off from the surface of the wing, and the water cannot flow to the rear edge of the wing to cause icing again on the surface of the wing.
本发明公开了一种除冰装置及无人机,在每个机翼表面安装柔性加热器、电容传感器及喷涂一层超疏水涂层,根据冰和水的介电常数不同及介电常数随着温度的变化不同,当机翼上结冰时,电容器的介电常数发生变化,进而导致电容器的电容发生变化,电容传感器将这种变化信号传递给控制器,控制器根据电容量控制柔性加热器的工作状态,实现机翼的除冰;此外,超疏水涂层可使过冷的水滴撞击在机翼表面后直接滚落,而不会粘附在机翼表面后凝固结冰;同时,超疏水涂层还可以防止回流结冰,即超疏水涂层可使机翼前缘的结冰融化后产生的水直接会从机翼表面滚落,而不会向机翼后缘流去导致机翼表面上的再次结冰。
