Abstract
The invention discloses an antifouling silencer strengthening device which comprises a first casing and a second casing which are both semicircular cylinders, the first casing and the second casing are matched to form a cylinder structure, and the inner walls of the first casing and the second casing extend inwards to form at least two partition plates distributed in the axial direction of the cylinder. During installation, the space among the first casing, the second casing and the silencer is divided into at least one silencing cavity through the partition plates, a silencing material is arranged in the silencing cavity, an annular sealing groove is further formed in the partition plate, and a rubber block is arranged in the sealing groove. The strengthening device effectively and conveniently solves the problem that a silencer is poor in noise reduction effect in the use process. The rubber block is arranged in the sealing groove to ensure that a sound insulation material in the whole sound insulation cavity is waterproof and antifouling, and the service life of the device is prolonged by means of the partition cavity.
