Device and method for recognizing leakage points of building outer wall water spraying test

The invention provides a device and a method for recognizing leakage points of a building outer wall water spraying test, and provides a precise recognition device for the leakage points of the fabricated building outer wall water spraying test, a second hydraulic hose of a special container is connected with a first hydraulic hose of tap water, and an intelligent control valve is arranged at the joint; the intelligent control module can remotely control opening and closing of the intelligent control valve, and real-time control over mixing of the color developing reagent and tap water is achieved. A color developing reagent is combined with tap water to carry out a water spraying test, a leakage part can be intuitively and efficiently judged by observing colors, omission can be avoided, and the inspection precision and efficiency are improved; the leakage point can be visually identified, the difficulty of accurately judging the leakage point is reduced, the detection efficiency is improved, it is ensured th
