Device for detecting water leakage of water pipe in wall

The utility model relates to the technical field of water leakage detection devices, in particular to a device for detecting water leakage of a water pipe in a wall body, which comprises a handle group, the outer wall of the handle group is fixedly connected with the inner wall of a shell group, a sealing ring is attached to the wall surface or the underground, sound enters from a sound receiving opening and is transmitted into a diaphragm capsule through a sound receiving column, the diaphragm capsule absorbs the water leakage sound, and the water leakage is detected. After the diaphragm capsule absorbs sound, the sound is fed back to the enhancement block, the enhancement block transmits the sound to the diffraction iron through the connecting column and the connecting strip, the diffraction iron transmits a data signal to the data block through the coil and the contact block, the data block transmits data to the circuit board, the circuit board analyzes the data, and the analyzed data is displayed on the d
