[0053] (9) When ending the diving after surfacing, turn off the power control switch on the waist-mounted power supply battery.

[0054] The present application utilizes the standard diving posture of a diver, fixes the thrusters on both sides of the diver's thighs, fixes the angle controller on the knee joint, and has two control rods and curved arms connected to the angle controller, the control rods and curved arms are respectively bound to the inner sides of the thighs, the power supply battery is fixed on the waist, the working state of the thrusters is adjusted and controlled through the included angle between the thighs of the diver, including forward movement, variable speed forward movement, reverse movement, turning, spin, etc., in addition to the power switch, the entire operation process only relies on the diver to adjust the included angle between the thighs for control, and completely does not need to be controlled by hand; in addition, the present application is also provided with a diving depth detector for monitoring the ascending speed of the diver, which can cut off the working state of the thrusters when the ascending speed is too fast, to prevent the danger caused by the diver's unconscious fast ascending due to incorrect posture or fast ascending during the ascending process.

[0055] The present application is divided into left and right parts, and a waist-mounted power supply battery is used as the power supply, the waist-mounted power supply battery is made to be detachable, and can be detached and discarded like the weight bag of a diver after the power is cut off in an emergency.

[0056] The control part of the present application is called an angle controller, which is divided into left and right independent angle controllers, the left angle controller is driven by the left thigh and calf to control the left thruster, and the right angle controller is driven by the right thigh and calf to control the right thruster; the control rod and curved arm are fixed on the angle controller, and the control rod and curved arm are respectively fixed on the thighs by a binding belt, when the angle of the thighs changes, the angle controller will be rotated through the curved arm and control rod to make the thrusters be in different working states.

[0057] ​​The cable control of the present application is shown in Fig. 7. Except for sharing one waistband battery, the control circuit system is divided into left and right sets, respectively corresponding to the two angle controllers installed on the diver's left and right legs, respectively controlling the operation of the left and right two diving thrusters. The photoelectric switch circuit of each position is connected to a relay control box, and the relay control box is connected to the corresponding thruster.

[0058] A diving depth detector is installed on the power supply battery line, which will automatically detect the diver's ascent speed during the operation of the present application. When the diver's ascent speed is greater than the maximum ascent speed specified by PADI or other diving organizations (such as 9 meters / minute) due to an imbalance in posture or during normal ascent, the diving depth detector will automatically turn off the control of the thruster by the angle controller on the present application, stopping the thruster from working, thereby avoiding the situation that the diver's ascent speed is too fast due to the influence of the present application, and preventing the diver from being in danger.

[0059] The working mode of the present application is shown in Figs. 8, 9, 10, and 11. By changing the angle of the diver's legs, the relative rotating position of the inner and outer discs of the angle controller is driven, the working state of the thruster is controlled and changed, and through the angle change of the diver's legs, the switch of the angle controller is driven, so that the diver can be in multiple different diving states.

[0060] Reverse state: see Fig. 8. When the diver's legs are at a position angle ≤90°, the LED light of the angle sensor outer disc is located at the photoelectric sensor window position of the 90° groove of the inner disc, starting the reverse working state of the thruster. When the diver's left and right legs are at this angle, the diver can move backward at a constant speed.

[0061] Stationary state: see Fig. 9. When the diver's left and right legs are at an angle position >90° - ≤135°, the LED light on the outer disc of the angle sensor is located at the photoelectric sensor window position of the >90° - ≤135° groove of the inner disc, stopping the operation of the thruster, and the diver is in a stationary state.

[0062] Forward state: see Fig. 10. When the diver's left and right legs are at an angle position >135° - ≤180°, the LED light on the outer disc of the angle controller is located at the photoelectric sensor window position of the >135° - ≤180° groove, and the greater the angle, the greater the gear position representing the thruster speed. The diver can control the gear position of the thruster speed by adjusting the angle of the legs within this angle range. When the angle reaches or approaches 180°, the thruster speed is the largest.

[0063] Turning state: see Fig. 11, when the diver needs to turn, just retract the leg to be turned to, keep the clamps of the big and small legs between >90° - ≤135°, and keep the clamps of the big and small legs on the other side between >135° - ≤180°, then turn under the push of the propeller on one side.

[0064] Turning in place state: see Fig. 12, when the diver needs to turn in place, just keep one of the big and small legs ≤90° (the propeller on this side is in reverse state), and keep the other big and small leg >135° - ≤180° (the propeller on this side is in forward state), then the diver can turn in place.
