The invention belongs to the technical field of propellers of unmanned aerial vehicles, and particularly relates to an electric heating propeller of a multi-rotor unmanned aerial vehicle, the electric heating propeller comprises a propeller, the propeller comprises a fixing block and blades distributed on the outer side of the fixing block and fixedly connected with the fixing block, and the inner wall of each blade is provided with an oval mounting groove; an electric heating wire is mounted on the inner wall of the elliptical mounting groove; the inclination of the paddle is gradually reduced from left to right, the right side of the paddle is lower than the left side, a first flange is arranged at the top end of the paddle, the top end of the first flange is an arc surface, the left side of the arc surface of the top end of the first flange is a first convex arc surface, and the right side of the arc surface of the top end of the first flange is a first concave arc surface; a second flange is arranged at the bottom end of each paddle, a cambered surface is arranged at the bottom end of each second flange, and a second concave cambered surface is arranged on the right side of the bottom end of each cambered surface. The paddles are heated through the electric heating wires, so that the ice surface is melted, icing in the subsequent use process is avoided, and the danger coefficient is reduced.
本发明公开的属于无人机螺旋桨技术领域,具体为一种多旋翼无人机的电加热螺旋桨,包括螺旋桨,所述螺旋桨包括固定块,以及分布于固定块外侧并与其固定连接的桨叶,所述桨叶的内壁开设有椭圆形安装槽,所述椭圆形安装槽的内壁安装有电热丝;所述桨叶的倾斜度为从左往右依次递减,桨叶的右侧低于左侧,所述桨叶的顶端设有凸缘一,所述凸缘一的顶端设为弧面,所述凸缘一的顶端弧面左侧设为凸形弧面一,右侧设为凹形弧面一;所述桨叶的底端设为凸缘二,所述凸缘二的底端设为弧面,该弧面的底端右侧设为凹形弧面二,本发明通过电热丝对桨叶进行加热,从而使得冰面融化的同时,避免后续使用过程中结冰,减低危险系数。
