The invention provides a blocking rotor unmanned aerial vehicle capable of preventing raining resistance, which comprises an unmanned aerial vehicle and a shielding object, a plurality of rotors are arranged in the unmanned aerial vehicle, the shielding object is arranged above the rotors, the shielding object is an umbrella-shaped shielding object or a spiral shielding object, and the overlook projection surface of the shielding object can shield an outer circular ring of a propeller of the unmanned aerial vehicle. The shielding object is provided with a screen, the surface material of the shielding object is a hydrophobic material, and a hollow hole is formed in the middle of the shielding object, so that the blocking of the air inlet amount of the propeller below the shielding object is reduced, and the capability of the unmanned aerial vehicle for resisting heavy rain and severe weather, particularly the heavy rain and the heavy rain are prevented, the power performance loss of the unmanned aerial vehicle is reduced, and the endurance of the unmanned aerial vehicle is reduced; the substantial effects of falling prevention, damage prevention and flight time loss prevention are achieved.

    本发明提供一种防止下雨阻力的挡旋翼无人机,包括无人机和遮挡物,无人机内置多个旋翼,旋翼的上方设置遮挡物,遮挡物为伞状遮挡物或螺旋状遮挡物,遮挡物的俯视投影面能遮住无人机的螺旋桨的外圆环,防止大雨滴落到盖其下螺旋桨,遮挡物设有筛网,遮挡物的表面材料为疏水材料,并且中间有中空孔,减少对其下方的螺旋桨进风量的阻挡,让无人机抵御大雨恶劣天气的能力,特别是防大雨及以上,对无人机动力的性能损耗和续航的降低,起到了实质性的防摔、防坏、防飞行时间损耗的效果。
