A plurality of first sound insulation devices 2 corresponding to the sound insulation devices 2 are arranged in the plant body 1. An adjusting portion 3 is used to install and fix the ends of the first sound absorbing panel 21 and the second sound absorbing panel 22 that are close to each other. The first adjusting portion 3 can drive the ends of the first sound absorbing panel 21 and the second sound absorbing panel 22 that are close to each other to move, so as to adjust the angle of the first sound absorbing panel 21 and the second sound absorbing panel 22.
