Low-speed spiral body power propeller and unmanned underwater vehicle

The utility model relates to a low-speed spiral body power propeller and an unmanned underwater vehicle. The invention belongs to the technical field of underwater unmanned underwater vehicles. The propeller comprises a propeller body, spiral blades installed on the outer surface of the propeller body and a power conversion device installed in the propeller body. The propeller body is arranged tobe of a conical structure with the section being a tip at the left end. The right end of the propeller body is inwards provided with a concave cavity; the spiral blade is installed on the outer surface of the propeller body in a spiral curve shape, one end of the spiral blade starts from the right end of the propeller body, the other end of the spiral blade ends at the tip of the left end of the propeller body, and the technical problem that in the prior art, electric energy is inconvenient to supply to underwater unmanned underwater vehicle long-voyage equipment or deep and far sea sensors issolved. 本实用新型涉及一种低速螺旋体动力推
