Abstract

Provided is a leakage detection device using siphon principle. The leakage detection device includes a water level measuring tube that has a closed lower end portion and includes a first inflow port through which leakage water flows, a water collection tank that accommodates the water level measuring tube, a discharging pipe that includes 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, and a water level measurer that detects a level of the leakage water flowed into the water level measuring tube.

Claims

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.

2. The leakage detection device of claim 1, further comprising an inserting pipe that vertically extends and is disposed in the water level measuring tube, wherein the water level measurer measures a level of the leakage water flowed into the inserting pipe.

3. The leakage detection device of claim 2, further comprising an exhaust hole formed at a sidewall of the inserting pipe,

wherein when the leakage water flows into the inserting pipe, internal air of the inserting pipe is discharged through the exhaust hole.

4. The leakage detection device of claim 2, further comprising a flange provided at an upper end portion of the inserting pipe, wherein the water level measurer is mounted on the flange.

5. The leakage detection device of claim 1, further comprising a leakage water overflow preventing hole formed at the water level measuring tube, at a position higher than position of the connecting pipe.

6. The leakage detection device of claim 1, further comprising a draining port that is formed at a bottom of the water level measuring tube and selectively opens or closes the bottom of the water level measuring tube to drain the leakage water flowed into the water level measuring tube.
