Storage pressure test base for underwater blowout preventer and pressure test system

The utility model relates to the technical field of ocean drilling and production equipment, in particular to a storage pressure test base and a pressure test system for an underwater blowout preventer. A storage and pressure test base for an underwater blowout preventer is used in cooperation with the underwater blowout preventer and a bearing type pressure test pile and comprises a hollow main frame body, and multiple sets of telescopic ejector rods are arranged on the main frame body; the underwater blowout preventer is transferred to the bearing type pressure test pile, a gap exists between the lower portion of the underwater blowout preventer and the pressure test base body, and the multiple sets of telescopic ejector rods are arranged in the gap. By operating the multiple sets of telescopic ejector rods, the telescopic ejector rods are lifted to make contact with the blowout preventer set frame and are stressed, and the whole underwater blowout preventer set is borne or lifted.
