The high-pressure gas cylinder 120 is installed on the back frame structure 110 and is made of aviation aluminum material, which has the characteristics of light weight and high pressure resistance. A switch valve 170 is installed at the outlet of the gas cylinder for controlling the on-off of the gas. The switch valve 170 adopts a quick opening and closing design to ensure that the gas source can be immediately cut off in an emergency. Two pipelines are led out from the switch valve 170, the main gas conveying pipe 130 is connected to the pneumatic driving mechanism 140, and the other end of the gas conveying branch pipe 180 is provided with a gas pressure gauge 190 for real-time monitoring of the gas pressure in the gas cylinder.

A one-way exhaust valve 230 is arranged on the shell, which can timely exhaust the gas driven by the high-pressure gas cylinder 120, and at the same time prevent water from entering the interior of the pneumatic driving mechanism 140, thereby prolonging the service life of the equipment. A spiral propeller 150 is installed at the output shaft end of the driving mechanism, and a protective cover 240 is arranged around the propeller, which can prevent foreign matter from entangling and also avoid accidental harm to the rescued object. A speed adjusting knob 210 and a steering adjusting button 220 are arranged on the driving mechanism, allowing the rescuer to accurately control the propelling force and direction according to the actual water flow. The speed adjustment adopts a stepless speed change design, which can realize smooth transition from zero to maximum propelling force.
