The present invention discloses a self-heating life jacket air bag gas supply tank in the technical field of life jacket gas supply tanks, comprising a tank shell, a switch for triggering the generation of gas, a battery for powering supply and an ignition head for triggering the gas generation of a gas generating agent, wherein the switch is fixedly arranged on the inner wall of the bottom end of the tank shell, and the switch contact passes through the tank shell, and the battery is fixedly arranged on the inner wall of the tank shell at the upper end of the switch; the ignition head is fixedly arranged on the upper side of a partition fixedly arranged on the inner wall of the tank shell at the upper end of the battery, and passes through the partition; the present invention solves the problem that existing gas storage tanks are often inflated quickly, thereby quickly filling the life jacket to provide buoyancy, and since the coolant and the gas generating agent are encapsulated in the two cavities of the gas tank, instantaneous excitation may cause the high-temperature gas to not have time to quickly mix with the coolant, thereby causing the high-temperature gas to directly enter the life jacket, which may cause the life jacket to be damaged and fail due to high temperature.

This invention discloses a frogman underwater propulsion vehicle and its assembly method, comprising a main body shell, an adjustment assembly, and a transport compartment. A fairing and a propeller hub are installed at the tail of the main body shell, with propeller blades evenly distributed circumferentially around the hub. The adjustment assembly includes a sliding guide rail, a limiting rod, a pulling rod, a sliding block, a connecting block, a rotating shaft, a suspension block, and a limiting hole. The sliding guide rail includes two sliding grooves at the top and bottom of the adjustment assembly. The transport compartment includes a water pump adjustment compartment, a ballast compartment, a cargo compartment, and a frame. This invention adjusts the center of gravity of the transport device through the adjustment assembly, increasing the stability of the underwater propulsion vehicle during navigation. By setting up the ballast compartment to ballast and de-ballast the transport device, the frogman underwater propulsion vehicle maintains neutral buoyancy at all times, thereby achieving higher propeller efficiency.
