PURPOSE: A water tank device for automatically draining is provided to store only sea water in a tank through an inlet pipe and to automatically discharge seawater to the outside using a pump when detecting a predetermined water level using a water level detector. CONSTITUTION: A water tank device (100) for automatically draining comprises an inlet pipe (112), a tank (110), a water level detector (140), an outlet unit, a pump (170), and a control unit (130). The tank stores sea water which flow through the inlet pipe. The water level detector measures the amount of sea water stored inside the tank to deliver the measurement result to the control unit. The outlet unit is joined to the bottom of the tank to discharge sea water to the outside. |
