Generator air cooler water leakage monitoring device

The utility model relates to the technical field of water leakage monitoring, in particular to a generator air cooler water leakage monitoring device which comprises a water tank, one side of the top of the water tank is fixedly connected with a laser generator, the other side of the bottom of the water tank is fixedly connected with a light sensation panel, and the outer side of the water tank is fixedly connected with a leakage-proof shell. The water tank has the advantages that according to the refraction principle of light emitted by the laser generator in water, the irradiation point of laser deviates leftwards and gradually moves leftwards along with rising of the water level until the water tank is filled with water, and the irradiation point of the laser is far away from the diagonal position of the water tank, so that the water tank is fully filled with water. When leaked cooling water is collected from the air cooler in the water tank, laser deviates leftwards through a refraction irradiation point
