Gate water leakage detection system

The utility model discloses a gate water leakage detection system which comprises a water leakage position detection mechanism, the water leakage position detection mechanism comprises a U-shaped heating device and a U-shaped temperature measuring device, and the height of the heating part of the U-shaped heating device and the height of the temperature measuring part of the U-shaped temperature measuring device are both higher than the water level of the downstream side of a gate. The widths of the U-shaped heating device and the U-shaped temperature measuring device are matched with the gate; the top end of the U-shaped heating device is higher than the upstream side water level of the gate; the U-shaped heating device is used for being arranged on the upstream side of the gate and heating water at the left side, the right side and the bottom side of the gate. The U-shaped temperature measuring device is used for being arranged on the downstream side of the gate and measuring the water temperature of the le
