The present invention belongs to the technical field of subsea equipment, and specifically pertains to a thrust reversal type emergency jettison device for an underwater vehicle. A thrust reversal type emergency jettison device for an underwater vehicle, comprises a thrust reversal mechanism, the thrust reversal mechanism comprises a casing and a gas reaction compartment provided in the casing; the gas reaction compartment communicates with a gas passage in a shell of the casing through a gas pipe; and a bottom end cover is provided at a bottom of the gas reaction compartment, and the bottom end cover is hermetically connected with the gas reaction compartment through a cylinder mechanism, and falls off automatically when a gas pressure in the gas reaction compartment increases. Compared with the prior art, the present invention can provide a reverse thrust for an underwater vehicle in an emergency, help the underwater vehicle to ascend, prevent the underwater vehicle from being trapped in bottom sediment, and improve safety.
