Embodiment Construction

[0055] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the following examples.

[0056] see Figure 1-4 understand the invention. in, figure 1 is a top view view, figure 2 reflects the orientation of the structural air duct 100 in use, figure 2 The lower end of the mid-wind pipe body 1 is used to connect the deck or segment boundary 200 .

[0057] An embodiment of the present invention provides a structural air duct for a ship with a sound-absorbing device, which is applied in a ventilation system of a ship, and is especially suitable for a large ship. Preferably, the structural air duct 100 is arranged between the decks on both sides of the ship. During the construction process, the structural air duct 100 between any two decks is operated separately, and then the adjacent structural air duct 100 is welded and fixed.

[0058] The structural air duct 100 includes an air duct main body 1 , ...

Abstract

The invention discloses a structural air duct with a sound-absorbing device for ships, an installation method thereof, and a ship. The structural air duct includes an air duct main body, a first support component, a plurality of sound-absorbing sheet units and a second support component. The first support component is placed horizontally in the main body of the air duct and fixed at the first end. The individual sound-absorbing sheets are fixedly connected to the main body of the air duct and / or the first support member, and adjacent individual sound-absorbing sheets are arranged at intervals along a direction perpendicular to the axial direction of the main body of the air duct. The second support component is built into the second end of the main body of the air duct, and is fixedly connected with the main body of the air duct and the sound-absorbing sheet. The present invention has low cost and strong operability for matching large-sized sound-absorbing sheets, reduces the assembly difficulty of installing the structural air duct on the hull, simplifies the installation steps, improves assembly efficiency, and has better effects on the sound-absorbing sheets The fixing effect improves the reliability of the single sound-absorbing sheet.

Description

technical field [0001] The invention relates to a structural air duct of a marine ventilation system, in particular to a structural air duct with a sound-absorbing device, an installation method thereof, and a ship. Background technique [0002] In the marine ventilation system, the noise reduction equipment is an auxiliary device installed in the structural air duct to eliminate the noise generated when the equipment is working. At present, it is usually realized by installing a silencer in the structural air duct, and the silencer needs to be installed in two sections of the structure position between the seams. [0003] As the tonnage of various types of ships increases, the capacity of ship ventilation becomes larger and larger, and the size of the corresponding hull structure air duct is also huge, which requires a larger silencer to realize. However, in the actual production process, it is found that on the one hand, it is difficult to match a large silencer that meet...
