Disclosed is a residual water discharging device for building a vessel, which has an improved structure to improve efficiency of removing residual water. The residual water discharging device includes: a water collection container including an inlet in which residual water flows inside and a drain which the residual water is discharged from, wherein the water collection container also includes a first valve opening and closing the drain; a partition member partitioning an inner space of the water collection container into an upper water collection chamber and a lower water collection chamber and having a connection hole at the center, wherein the partition member also includes a second valve opening and closing the connection hole at a lower end; a foreign substance trap unit collecting foreign substances flowing with the residual water and discharging the residual water from which the foreign substances are removed to the upper water collection chamber; a level sensor sensing a predetermined water level of the residual water collected in the lower water collection chamber; a suction unit installed in the upper part of the water collection container and integrally having an air ejector to generate a suction force in the water collection container; and a control unit controlling the first valve, the second valve, and the level sensor. The control unit discharges the residual water filled in the lower water collection chamber through the drain by blocking the second valve and opening the first valve for a predetermined time in a case that a sensing signal is output by a level sensor as the residual water is filled in the lower water collection chamber and fills the upper water collection chamber with the residual water flowing inside through the inlet. The control unit also fills the lower water collection chamber by dropping the residual water collected in the upper water collection chamber to the lower water collection chamber through the connection hole by blocking the first valve and opening the second valve after the first valve is open for the predetermined time.
선박건조용 잔수배출장치가 개시된다. 개시된 잔수배출장치는 잔수가 유입되는 유입구와, 잔수가 배출되는 배수구가 형성되며, 상기 배수구를 개폐하는 제1밸브가 구비된 집수통; 상기 집수통의 내부공간을 상부집수실과 하부집수실로 구획하며 중앙에 연통공이 형성되며, 하단에 상기 연통공을 개폐하는 제2밸브가 설치된 구획부재; 잔수와 함께 유입되는 이물질을 포집하고, 이물질이 제거된 잔수를 상기 상부집수실에 배출하는 이물질 트랩부; 상기 하부집수실에 집수된 잔수의 소정 수위를 감지하는 레벨센서; 상기 집수통의 상부에 설치되어 상기 집수통에 흡입력을 발생시키도록 에어이젝터가 일체로 형성된 흡입유닛; 상기 제1밸브, 상기 제2밸브 및 상기 레벨센서를 제어하는 제어부;를 포함하며, 상기 제어부는 상기 하부집수실에 잔수가 채워져 상기 레벨센서에서 감지신호가 출력된 경우, 상기 제2밸브를 차단하고, 상기 제1밸브를 기 설정시간동안 개방시켜 상기 하부집수실에 채워진 잔수가 상기 배수구를 통해 배출됨과 동시에 상기 상부집수실에는 상기 유입구를 통해 유입된 잔수가 채워지게 하고, 상기 제1밸브가 기 설정시간동안 개방된 다음, 상기 제1밸브를 차단하고 상기 제2밸브를 개방시켜, 상기 상부집수실에 집수된 잔수가 상기 연통공을 통해 상기 하부집수실로 떨어져 채워지도록 구성되는 것을 특징으로 한다.
