The invention discloses a noise-reducing plate based on a ship engine room and a noise-reducing method thereof, comprising: a sound-absorbing component arranged in an assembly frame body, an assembly groove is arranged on the inner side of the assembly frame, a strip track is arranged in the assembly groove, and the sound-absorbing component includes: The sliding plate and the fixed plate are arranged sequentially from top to bottom, the sliding plate and the fixed plate are connected by a plurality of lifting columns, the bottom surface of the fixed plate is provided with an installation cavity, and an adjustment member is arranged in the installation cavity. The adjustment member includes a telescopic rod and a flexible partition arranged on the telescopic rod. The telescopic rod is arranged coaxially with the second through hole, and the bottom surface of the telescopic rod is connected to the bottom surface of the installation cavity. The overall shape of the flexible partition is a cone, and the flexible partition The top is fixedly connected with the telescopic rod. Use the length adjustment of the telescopic rod to change the height of the flexible partition, so as to absorb the noise according to the different audio frequency of different noises, and achieve the absorption of multiple noises at the same time, so as to achieve the best noise reduction effect.
Description
technical field [0001] The invention relates to the field of noise reduction in a ship engine room and the field of mechanical device manufacturing, in particular to a noise reduction plate based on a ship engine room and a noise reduction method thereof. Background technique [0002] With the rapid development of the shipbuilding industry, the noise problem of propulsion hosts and diesel generator sets in the engine room is becoming more and more serious. Since the propulsion power of the ship and the generator set are arranged in the narrow engine room, the two major noise sources in the engine room: the noise of the propulsion main engine and the noise of the generator set make the working environment in the engine room very bad. In addition, the work of the crew in the engine room Therefore, this strong noise not only seriously affects the work efficiency of the crew, damages their physical and mental health, but also seriously pollutes the surrounding sound environment....
