The invention provides a foldable propeller and an underwater glider. The foldable propeller comprises a propeller hub, a worm, a stepping motor, a coupler and at least three blades. A worm wheel is arranged at the top end of the paddle, the worm wheel is meshed on the worm, the worm is respectively connected with the propeller hub and the stepping motor, and the stepping motor is used for driving the worm to rotate and driving the paddle to expand or contract relative to the worm; and the propeller hub is connected with the coupler. According to the foldable propeller provided by the invention, the stepping motor is in power connection with the propeller blade with the worm wheel through the worm, so that the propeller blade can be contracted or expanded in the propeller hub under the driving of the stepping motor, and the propeller blade can be used as a common propeller to be connected with a power device in an underwater glider to realize normal driving when the propeller blade is expanded; when the underwater glider glides, the blades can be gathered and contracted, the gliding resistance can be greatly reduced, and the gliding voyage and efficiency are improved.
本发明申请提供的一种可折叠螺旋桨及水下滑翔机,其中可折叠螺旋桨包括桨毂、蜗杆、步进电机、联轴器和至少三个桨叶;所述桨叶的顶端设置有蜗轮,所述蜗轮啮合在所述蜗杆上,所述蜗杆分别与所述桨毂和所述步进电机连接,所述步进电机用于驱动所述蜗杆旋转并带动所述桨叶相对所述蜗杆张开或收缩;所述桨毂与所述联轴器连接。本发明提供的可折叠螺旋桨中步进电机与带有蜗轮的桨叶通过蜗杆动力连接,可在步进电机的驱动下实现桨叶在桨毂中收缩或张开,张开时可作为普通螺旋桨与水下滑翔机中的动力装置连接以实现正常驱动,在水下滑翔机滑翔时又能实现桨叶的聚拢收缩,可大幅度降低滑翔阻力,提高滑翔航程和效率。
