The invention discloses an oxygen safety system of an underwater unmanned closed cabin. The oxygen safety system of the underwater unmanned closed cabin includes a liquid oxygen storage tank, an oxygen compressor, a high-pressure oxygen buffer tank group, an oxygen scavenger, a molecular sieve oxygen generator, an air compressor, a rupture membrane, a pneumatic valve, a one-way valve, a stop valve, a closed cabin, a safety valve, a pressure sensor, an oxygen concentration sensor, a pressure gauge and the like. The oxygen safety system of the underwater unmanned closed cabin can effectively absorb the tail exhaust oxygen generated by the operation of a fuel cell stack and the oxygen generated by a pipeline leakage, and realizes that the oxygen concentration in the closed cabin is below a safe concentration range when the oxygen leakage or oxygen tail exhaust with different conditions and different levels occurs on an underwater carrier platform, which prevents fire or explosion in the cabin, realizes nitrogen cyclic utilization in the closed cabin, and has high safety factor.
