If the rescue diving device reaches the underwater target preset area of the rescue target, step S13; if the rescue diving device does not reach the underwater preset area of the rescue target, step S12 is repeated until the rescue diving device reaches the underwater preset area of the rescue target.

Step S13: When the rescue diving device reaches the underwater target preset area of the rescue target, the control system 3 controls the high pressure gas in the high pressure storage cylinder 6 to stop entering the air mixing chamber 15, and stops the operation of the power device 1 so that The rescue diving device is located in the underwater preset area. Specifically, the control system 3 closes the third check valve 11 and the first check valve 7 connected to the first high pressure gas pipe 12 such that the high pressure gas in the high pressure storage cylinder 6 stops entering the mixing chamber 15.

Step S14: The control system 3 controls the high pressure gas in the high pressure storage cylinder 6 to enter the depth balance air chamber 8 to expand the depth balance air chamber 8 to generate buoyancy, so that the rescue diving device floats to rescue the target. Rescue. After the float, the rescue target is located on the surface of the rescue diving device, after which the power device 1 is turned on to return the rescue diving device to the rescue center base.
