The invention discloses a detachable propeller. The detachable propeller comprises a hub, blades and an end cover, wherein a plurality of paddle inserting grooves are formed in a side surface of the shaft hub in the axial direction in a penetrating mode, the paddle inserting grooves at least have a certain distance in the depth direction of the paddle inserting grooves, a linear distance between the two oppositely-arranged side walls of the paddle inserting grooves is gradually increased within the certain distance, and the multiple paddle inserting grooves are evenly distributed in the circumferential direction of the shaft hub; the propeller blade comprises an inserting part, the shape of the inserting part is matched with that of the propeller blade inserting groove, and the inserting part is inserted into the propeller blade inserting groove, so connection between the propeller blade and the shaft hub is realized; and end covers are arranged at two ends of the shaft hub and limit the paddles in the axis direction of the shaft hub. According to the designed composite material propeller, strength and rigidity of the connecting structure can be effectively improved through the spiral inserting structure of the propeller blades and the hub, and stability of the propeller during operation is guaranteed.

    本发明揭示了一种可拆卸螺旋桨,包括轴毂、桨叶以及端盖;所述轴毂侧表面沿其轴向贯穿设置有桨叶插接槽,所述桨叶插接槽沿其深度方向上至少存在一段距离,且在该段距离内,所述桨叶插接槽相对设置的两个侧壁之间的直线距离逐渐增大,若干所述桨叶插接槽沿所述轴毂周向均匀分布;所述桨叶包括一插接部,所述插接部的形状与所述桨叶插接槽的形状相适配,所述插接部插入所述桨叶插接槽,实现所述桨叶与所述轴毂之间的连接;端盖,被配置于所述轴毂的两端,在所述轴毂的轴线方向上实现对所述桨叶的限位。本发明设计的复合材料螺旋桨,其桨叶和轮毂的螺旋插接结构可以有效提高连接结构强度和刚度,保证螺旋桨运转时的稳定性。
