The invention relates to a hydropower station cooling water leakage intelligent detection method that comprises the steps that a rotary camera and an infrared imager are arranged on a mobile inspection robot, water leakage elements are determined through the temperature difference between equipment and circulating water in the operation process, temperature measurement point marking is conducted on flowing water inevitable points of an existing water leakage area in advance, and under the non-contact condition, two different algorithms are adopted to judge overall regional water leakage and local water leakage respectively, the water leakage accuracy and inspection efficiency of the water cooling system are improved, the method has the advantages of being good in real-time performance, safe and reliable, the problem that conventional inspection is high in labor intensity is solved, and the water flow and pressure in the inspection process have no influence on inspection. And other auxiliary lines are not need
