Abstract
A submersible propeller that includes a battery and propellers in which: the propellers include a left propeller and a right propeller; front portions of the left propeller and the right propeller are connected to a waist-wearing power supply battery through a power supply cable for the left propeller and a power supply cable for the right propeller respectively. Rear portions of the left propeller and the right propeller are connected to a left angle controller and a right angle controller through a connection cable for the left angle controller and a connection cable for the right angle controller respectively. The left propeller and the left angle controller are symmetrically distributed left-and-right with respect to the right propeller and the right angle controller. By using angle controllers on the legs, various modes such as advancing, variable-speed advancing, retreating, turning, and in-situ spinning can be implemented.
