Gas-liquid storage and supply device and underwater equipment

Abstract

The utility model relates to a gas-liquid storage and supply device and underwater equipment. The gas-liquid storage and supply device comprises a liquid storage container which is provided with a first cavity, and the first cavity is used for storing driving liquid; the gas storage container is provided with a second cavity which is not communicated with the first cavity, and the second cavity is arranged in an expandable mode; the storage container is used for storing driving gas; the storage container is communicated with the gas storage container, the liquid storage container is used for being communicated with a power device, and the storage container is used for conveying the driving gas to the gas storage container to enable the second cavity to expand so as to drive the liquid storage container to convey the driving liquid to the power device. The mechanical energy of the high-pressure driving gas in the storage container is utilized, extra energy is not needed for pressurizing and conveying the driving liquid when the underwater equipment is used, the gas-liquid storage and supply device can be used under the condition of no electric power, the energy consumption of the gas-liquid storage and supply device is reduced, then the underwater equipment is prevented from having equipment faults, the maintenance difficulty is reduced, and the safety is high.
