Problems solved by technology

At the same time, due to the narrow space for the boat to enter and exit, the integral sound insulation cover cannot enter the cabin and install it.
[0004] Therefore, the current riveting, welding connection types, and integral sound insulation cover cannot meet the requirements of boats

Embodiment Construction

[0018] Referring to the accompanying drawings, an anechoic box for a closed cabin of a ship includes: a box body 1, and a flange nozzle gasket 2, a buckle 3, a handle 4, a shutter 5, an axial flow fan mounted on the box body 1 6. Muffler 7, observation window 8, temperature display window 9;

[0019] The box body 1 is the main body of the sound insulation cover, which isolates the power equipment from the direct sound transmission channel. From the outside to the inside, it is: panel, sound-absorbing material, and perforated plate; the box body 1 can be assembled by multiple unit modules as required. A buckle 3 is arranged at the connection of each unit module, and the buckle 3 is divided into a female buckle and a sub buckle, and the two adjacent unit modules are connected and fixed by the female buckle and the sub buckle;

[0020] There is an opening under the side of the box body 1, and a flange orifice gasket 2 is provided at the opening. The gap is sealed;

[0021] A ha...

Abstract

The invention belongs to the technical field of air noise control, and particularly relates to power equipment silencing of a closed compartment of a naval ship. A silencing box for the closed compartment of the naval ship comprises a box body, and a flange pipe orifice gasket, hasps, a handle, a louver, an axial flow fan, a silencer, an observation window and a temperature display window which are mounted on the box body. The silencing box has an excellent dismounting overhauling function. Box body blocks are connected and fixed in a hasp form, so that the silencing box is convenient for personnel to operate and maintain and convenience in mounting and disassembling of the silencing box is ensured; the box body is provided with the perspective observation window, so that an internal temperature and an internal operation state of equipment can be monitored in real time; gaps between the box body blocks can be well plugged by rubber sealing base plates so as to ensure silencing and sound insulating effect on the equipment.

Description

technical field [0001] The invention belongs to the technical field of air noise control, and particularly relates to noise reduction of power equipment in a closed cabin of a ship. Background technique [0002] The distribution of noise sources in ship cabin equipment is complex, especially the dense distribution of power equipment in the engine room, the small space in the cabin, and the high level of air noise, which have a great impact on the normal work, communication and even physical and mental health of the crew. [0003] When sound insulation is used for power equipment, sound insulation cover is usually used. The function of the sound insulation cover is to cover the equipment and achieve a certain sound insulation effect through the closed or semi-closed type. Sound insulation cover measures are widely used in large factories, usually made into sound insulation workshops or large sound insulation rooms. Compared with this kind of sound insulation products, due t...
