description The invention relates to the technical field of diesel engine noise reduction, and discloses a marine diesel engine noise reduction device based on wavelet threshold denoising, which comprises a diesel engine, a rotating shaft is arranged at the output end of the diesel engine, a protective cover is arranged at the connection of the rotating shaft and the diesel engine, and an oil receiving tank is in threaded connection with the bottom of the protective cover. The top of the protective cover is in threaded connection with an oil dripping tank, and a driving assembly is arranged on the side, close to the diesel engine, of the exterior of the rotating shaft. According to the device, after a roller drives a first clamping tooth to move to the front end position in a movable frame, the first clamping tooth makes contact with a second clamping tooth at the front end in the movable frame and generates upward stirring force on the second clamping tooth, so that the movable frame moves upwards, a first rotating disc
