The invention discloses an
underwater traveling device. A multifunctional
protective vest (4) can be put on and a binding band (9) can be tied up so that the
underwater traveling device is worn more fitly. An
oxygen cylinder (3) is installed on the multifunctional
protective vest (4), the
oxygen cylinder (3) is communicated with an
oxygen mask (7) through an oxygen hose (11), and the
oxygen mask (7) closely fits to the face by an
oxygen mask band (8), so that a user can breathe
underwater. A power supply cylinder (2) is installed on the multifunctional
protective vest (4) and provides
electric energy for a roll booster (1) through a power line (10). A waistband (18) is tied up on the
waist for bearing partial weight of a multifunctional leg plate (5), and then the binding band (9) is tied up on the
thigh. The power supply cylinder (2) or the
oxygen cylinder (3) is installed on the multifunctional leg plate (5) for providing more
electric energy or oxygen for the roll booster (1). A booster boot (6) can be put on, a sole frame (13) is controlled by the sole to rotate, and the rotation of the sole frame (13) enables a controller (12) to turn on or turn off the power supply of the roll booster (1), thereby controlling the operation of the roll booster (1). When the controller (12) turns on the power supply, the roll booster (1) operates to produce thrust.
