Leakage detection equipment based on noise analysis

The utility model discloses leakage detection equipment based on noise analysis, and relates to the field of crown leakage detection. The leakage detection equipment based on noise analysis comprises a detector and a sound insulation mechanism installed beside the detector and used for insulating noise, the sound insulation mechanism is provided with a sound insulation cover used for insulating noise and a screw rod used for fixing a probe, two sets of sliding grooves are formed in the sound insulation cover, and the two sets of sliding grooves are communicated with the sound insulation cover. The inner wall of the sliding groove is slidably connected with two sets of clamping plates, the two sets of clamping plates are used for fixing a probe, and the clamping plates are rotationally connected with the screw rod. According to the leakage detection equipment based on noise analysis, the position of the probe can be fixed, so that the probe does not collide with the sound-proof cover to generate noise in the m
