The invention discloses an unmanned aerial vehicle and a wing deicing device thereof. The wing deicing device comprises a deicing sleeve, at least one nitrogen cylinder and a reversing valve, the deicing sleeve sleeves the tail part of a wing, the nitrogen cylinder is communicated with the deicing sleeve through a gas delivery pipe, the reversing valve is arranged on the gas delivery pipe, and the reversing valve is provided with an exhaust port. When the reversing valve is located at a first position, the nitrogen cylinder is communicated with the deicing sleeve, nitrogen is continuously filled into the deicing sleeve through the nitrogen cylinder, an ice layer at the tail of the wing is removed through the nitrogen, and the deicing purpose is achieved; and when the reversing valve is located at a second position, the nitrogen cylinder is disconnected from the deicing sleeve, the deicing sleeve is communicated with the exhaust port, and nitrogen in the deicing sleeve is exhausted from the exhaust port, so that the nitrogen is prevented from influencing flying of the wings. The deicing sleeve is alternately inflated and deflated through the reversing valve, the tail of the wing is deiced according to needs, it is avoided that an ice layer on the tail of the wing influences safe flight of the wing, and the flight safety is improved.

    本发明公开一种无人机及其机翼除冰装置,机翼除冰装置包括除冰套、至少一个氮气瓶和换向阀,除冰套套于机翼尾部,氮气瓶与除冰套通过输气管连通,换向阀设于输气管上,且换向阀设有排气口。当换向阀处于第一位时,氮气瓶与除冰套相连通,氮气瓶向除冰套持续充入氮气,利用氮气清除机翼尾部的冰层,达到除冰目的;当换向阀处于第二位时,氮气瓶与除冰套断开连通,除冰套与排气口相连通,除冰套内的氮气从排气口排出,避免氮气影响机翼飞行。除冰套通过换向阀交替地进行充放气,按需对机翼尾部进行除冰,避免机翼尾部的冰层影响机翼安全飞行,飞行安全得到提升。
