Claim 6:
7. A base station, wherein the base station comprises: a base station body; and a pumping and drainage system; wherein the pumping and drainage system comprises:
a first water tank configured to be installed on the base station body, the first water tank being defined with a water storage cavity and a vent communicated with the water storage cavity; and
a gas source system;
in case the first water tank is installed on the base station body, the gas source system is communicated with the vent of the first water tank;
in case the gas source system is in a first state, gas in the water storage cavity is discharged through the vent and the gas source system successively, causing the water storage cavity to be in a negative pressure state, allowing fluid to be sucked into the water storage cavity; in case the gas source system is in a second state, gas is delivered to the water storage cavity by the gas source system through the vent, causing the water storage cavity to be in a positive pressure state, allowing fluid in the water storage cavity to be discharged.
