Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, when front deck 1 works, before small power generator group 101 works, front deck air draft need to first be opened
Door, air enter in cabin by the inlet air noise elimination blinds 103 being installed on front door 11, are acted on through ventilating fan on generating set,
Air with heat in a small amount of cabin reaches closed channel by generating unit radiators and reaches cabin through air exhausting soundproofing blinds 104
Outside, which meets required air quantity and the required air capacity that radiates during unit work；Generating set cigarette tail gas is by small-sized
102 row of smoke-discharging noise elimination device is to bilge side；Generating set produce noise be transmitted to surrounding in cabin, through cabin inner wall sound absorbing layer 4 sound absorption and
Nacelle siding 3 insulates against sound, and sound absorbing layer is made of sound-absorbing material 41 and porous plate 42, and noise is multiple between porous plate 42 and mineral wool
Reflection, and after porous plate 42 determines aperture and pitch-row, can occur resonance decay and reach noise reduction, and noise is out of my cabin at siding
Very little, for into exhaust outlet, noise is by the multiple sound absorption of noise reduction shutter, and measurement noise can be met the requirements out of my cabin.
The generating set can provide illumination, wall is inserted, electric power needed for the electronic work of cable reel and when maintenance of equipment can provide regulated power.
When rear deck 2 works, before electricity generation unit 201 works, it need to first open and pass through into, air draft shutter door, air
Air feed shutter window 204 and diaphragm III 2008, diaphragm II 2007 and diaphragm I 2006, reach power station
Unit, the unit produce amount of heat when working, hot-air reaches the exhaust air box being connected with sealing passage through unit ventilating fan,
Exhaust air box is by exhaust air box siding I 2001, exhaust air box siding II 2002, exhaust air box siding III 2003, IV 2004 and of exhaust air box siding
Exhaust air box partition plate 2005 forms, and the air with heat is through 203 row of air draft shutter to out of my cabin；Generating set cigarette tail gas is by the road
By large-scale 202 row of smoke-discharging noise elimination device to bilge side in exhaust air box；The generating set noise is larger, by nacelle siding 3 every
Sound, sound absorbing layer 4 absorb sound, and inlet air labyrinth room partition plate and exhaust air box partition plate, carry out sound insulation sound absorption, can in noise figure out of my cabin
Meet the requirements.The generating set can be that separate unit or multiple devices provide high-power power at the same time.
When work is carried out maintenance in cabin, entered by rear door 22 in cabin, the ventilating fan for forcing exhaust outlet 21 can be opened, by force
Air flow in cabin processed；In addition front deck small power generator group can be removed by front door 11, and rear deck electricity generation unit removes
When need to open cabin top maintenance door 23 hung out.
Ventilation shutter of the present invention（Except front deck air inlet）It is mounted in hatch door, when power station works, opens door at this,
