摘要： The disclosure provides a liquid taking device and a liquid taking method. The liquid taking device comprises a liquid taking bottle, a heavy ball and liquid taking ropes. The liquid taking bottle has a first mouth and a bottom opposite to the first mouth. The heavy ball is arranged in the liquid taking bottle. The liquid taking device can be controlled to reach different depths under the ground by the action of two liquid ropes. When the first mouth of the bottle is placed facing downward, the heavy ball blocks the first mouth of the bottle under its own gravity to prevent liquid leakage; when the first mouth of the bottle is turned upwards under the action of the liquid taking rope, the heavy ball falls onto the bottom of the bottle, such that an external liquid can flow into the liquid taking device, which has a good practical utility.

摘要： Salt caverns with an inner container for storing electrical energy as a flow battery are provided. The salt caverns with an inner container for storing electrical energy as a flow battery comprises an air bag, a second pipeline and a first pipeline. The airbag is located in an underground salt cavern, the salt cavern is full of brine, and a liquid electrolyte is stored in the airbag. One end of the second pipeline is connected with the airbag while the other end thereof is located on the ground, and the second pipeline is used for filling the liquid electrolyte into the airbag. The first pipeline sleeves the second pipeline, one end of the first pipeline is connected with a shaft inlet of the salt cavern while the other end thereof is located on the ground, and the first pipeline is used for discharging the brine from the salt cavern.

摘要： The present invention discloses a device, system and method triaxial compression test with/without jacket by gas confining pressure on rock, and belongs to the technical field of rock mechanics tests. The device includes a container, wherein an accommodating cavity is disposed in the container for placing a core sample, a first through hole and a second through hole are respectively disposed at an upper end of the container, the first through hole is used for penetration of an end cap for loading an axial pressure to the core sample, the second through hole is used for injecting a gas into the accommodating cavity so as to apply a gas confining pressure on the core sample, a third through hole is disposed at a lower end of a side wall of the container, and the third through hole is used for communicating the accommodating cavity with the triaxial cell so as to achieve pressure transfer and balance between the accommodating cavity and the triaxial cell. During application, the device is installed in the triaxial cell. The container is inflated by a gas inlet and outlet of the triaxial cell and a communicating tube, the internal pressure applied by a high pressure gas on a near field rock wall of a salt cave can be accurately simulated, and a triaxial compression test with/without jacket by gas confining pressure on rock is conducted.
