Rainproof structure used in silencer and silencer adopting structure

Abstract

The invention relates to a rainproof structure capable of reducing the equipment manufacturing cost and saving the use space used in a silencer and an exhaust silencer adopting the structure. The rainproof structure is characterized in that a water discharge mechanism is arranged on the top inside a machine case of the silencer and consists of a hollow case, a rectifying net, a rain blocking plate and a water discharge pipe, wherein the water discharge pipe is used for guiding out accumulated water on the rain blocking plate, and the upper end of the rectifying net is also fixedly connected with a rain guide component. The rainproof and rain discharge structure is arranged inside the machine case of the silencer, the function of the silencer for reducing the noise is not influenced, the external use space is also saved, and in an integral aspect, the cost is not greatly increased under the condition of adding new functions, so the equipment manufacturing cost is effectively reduced. The rainproof structure and the silencer have the advantages that the structure is simple, the layout is reasonable, the installation is convenient, the multifunction of a diesel engine for a boat is realized, the boat manufacturing cost is also reduced, and the space utilization rate of boat equipment is also reduced.

Description

Technical field

[0001] The present invention relates to a rainproof structure used in a muffler, in particular to a rainproof structure used for an exhaust muffler installed on a marine diesel engine and a muffler applying the structure. Background technique

[0002] At present, the common exhaust mufflers for marine diesel engines at home and abroad have only a single function of reducing noise. A few muffler manufacturers install a simple rain cap or elbow cover at the exit of the exhaust muffler. This method of draining rainwater is inefficient and often It is also necessary to install other rainwater removal equipment in the diesel exhaust system. Adopting this method not only increases the cost of ship manufacturing, but also takes up the space around the ship exhaust muffler. Therefore, the design of new multifunctional equipment is the current development trend of various marine equipment. Marine diesel engine exhaust mufflers are also in continuous development and updat...
