Abstract:
1. A leakage detection device using a siphon principle, the leakage detection device comprising: a water level measuring tube that has a closed lower end portion, and comprises a first inflow port through which leakage water flows; a water collection tank that accommodates the water level measuring tube; a discharging pipe that comprises a first inducing pipe vertically disposed in the water level measuring tube, a connecting pipe extended from an upper end portion of the first inducing pipe through a sidewall of the water level measuring tube, and a second inducing pipe extended from one end portion of the connecting pipe to a lower side of the water collection tank, a lower end portion of the second inducing pipe being disposed lower in position than a lower end portion of the first inducing pipe; a water level measurer that detects a level of the leakage water flowed into the water level measuring tube; and a second inflow port that is formed at the water level measuring tube and into which leakage water from an adjacent facility flows; wherein— an upper side of the water collection tank is closed by a tank cover, the first inflow port is formed at the same height as the tank cover, and the second inflow port is formed at a lower side in position than the first inflow port.
