Problems solved by technology

[0002] At present, the exhaust mufflers of marine diesel engines that are common at home and abroad only have a single function of reducing noise. A few muffler manufacturers install a simple rainproof cap or elbow cover at the outlet 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 exhaust system of the diesel engine
This approach not only increases the cost of ship manufacturing, but also takes up the space around the marine exhaust muffler

Embodiment Construction

[0021] The rainproof structure 1 used in the muffler of the present invention and the muffler applying the structure are mainly used in the exhaust device of a marine diesel engine. It includes a casing 4 of a muffler, a sound-absorbing material 5 placed in the casing 4, an exhaust connection pipe 2 installed on the exhaust port of a marine diesel engine, and a rainproof structure 1 arranged in the upper part of the casing 4.

[0022] The rainproof structure 1 is composed of six parts, including a shell 11, a rain shield 13, a rectifying net 12, a rain guide component 14, an exhaust connection pipe 2 and a drain pipe 3.

[0023] The shell 11 is made of 304 stainless steel, which is divided into an upper part and a lower part. The upper part and the lower part are connected as a whole. The upper part is a truncated cone shape with a small upper part and a large lower part. The top of the upper part is the rain inlet 6, and the rain inlet 6 The periphery is welded on the flange 7 of ...

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...
