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
The invention belongs to airborne noise and control technical field, the power-equipment particularly to naval vessels closed in spaces is eliminated the noise.
Background technology
In Naval Vessels Cabin, noise of equipment source distribution is complicated, and especially cabin internally-powered device distribution is intensive, narrow space in cabin, empty
Gas noise magnitude is high, normally works ship person, exchanges or even physical and mental health brings greater impact.
When power-equipment is made sound insulation process, generally use acoustic hood.The function of acoustic hood is by equipment cover, by closing
Or semi-enclosed pattern obtains certain defening effect.Acoustic hood measure is relatively broad in integrated mill's application, it is common that make
Sound insulation Factory Building or large-scale isolation booth.Compared with this sound insulation product, naval vessels have strictly due to narrow space, the maintenance of power-equipment
Dismounting and maintenance requirement, therefore the installation approach of ship power-equipment acoustic hood is had the requirement quickly opened and inspect.Simultaneously because ship
Turnover narrow space, monoblock type acoustic hood cannot enter cabin and installation.
Therefore, current riveting, it is welded to connect pattern, and all-in-one-piece acoustic hood cannot meet ship with requiring.
Summary of the invention
It is an object of the invention to: a kind of Sound Attenuator that can quickly open and inspect is provided, for naval vessels enclosed environment power-equipment acoustic hood
Extensively application provides technical scheme.
The technical scheme is that the silencer box of a kind of naval vessels closed in spaces, it includes: casing, and is arranged on casing
Flange mouth of pipe sealing gasket, hasp, shutter, axial flow blower, acoustic filter；
Casing is assembled by more than one unit module, arranges hasp in the junction of each unit module, and hasp is divided into box
And ZIKOU, connect fixing by box and ZIKOU between neighboring unit module；Wallboards of box body is followed successively by from outside to inside: panel, suction
Sound material, perforated plate；
Being provided with perforate below body side, be provided with flange mouth of pipe sealing gasket at tapping, flange mouth of pipe sealing gasket is for setting power
Encapsulation process is made in standby gap between pipeline flange and casing perforate；
Shutter, as the air inlet of heat transmission, is arranged in the middle lower region of casing；
Axial flow blower with acoustic filter is arranged on the opposite side of shutter on casing, and is positioned at the region at the middle and upper levels of casing.
Beneficial effect: (1) present invention has good dismounting maintenance function.Connected fixing between casing piecemeal by snap-type,
It is easy to human users and maintenance, it is ensured that the convenience of silencer box installation and removal, preferably meets the maintainability requirement of ship.
(2) present invention has good sealing, it is ensured that the noise elimination defening effect to equipment.Casing each unit module self is close
Envelope property is good；After being fixed by hasp between neighboring unit module, the gap between unit module can be had by rubber seal backing plate
Good closure.
(3) present invention has good defening effect, energy effective attenuation and the airborne noise of xegregating unit, preventing for personnel's erect-position
Protect and provide effectively support.
(4) present invention has good real time monitoring function, including noise elimination the temperature inside the box instant playback, and band fluoroscopic observation window,
Can time monitor internal temperature and device interior running status.
