Abstract
Go out side of a ship device the utility model discloses a kind of rectifier type marine main engine underwater exhaust, including airduct body, airduct body one end open is connected by flange with marine main engine exhaust outlet, and another end opening of airduct body is stretched out in the outside of ship hull plate, and it is characterized in that：It is provided with the outside of ship hull plate in the cowling panel of arc shape, cowling panel is fastened on the outside of ship hull plate, and cowling panel is extended over to airduct body other end open outer side from stem direction to stern direction.The utility model can effectively reduce the back pressure that hull appendages resistance and current are produced to exhaust, and guiding main exhaust spreads to topside, it is ensured that exhaust will not reduce propeller efficiency by the propeller suction positioned at hull bottom；The cambered design of deflector, effectively reduces exhaust resistance and advantageously reduces main engine power extraneoas loss；The device is directly fixedly installed in Ship Structure simultaneously, and certain rigid support is provided to blast pipe or muffler, favourable to vibration reduction of ship noise reduction.
Description
Technical field
The utility model is related to the exhaust equipment of ship power system, in particular to the one kind suitable for ship gas extraction system
Rectifier type marine main engine underwater exhaust goes out side of a ship device.
Background technology
The gas extraction system of modern ships is generally divided into underwater exhaust, topside exhaust, chimney exhaust and tail part exhaust, and the country sets
The exhaust mode that the barge and public affair ship of meter are more generally used is underwater exhaust and topside exhaust, and chimney is vented large-scale
Using more on ship such as merchant ship；Tail part exhaust mode in the spitkit of hydraulic jet propulsion, also there is a small number of propellers mostly
The ship of propulsion uses tail part exhaust mode, but the cost paid is the gross weight increase of gas extraction system, causes the speed of a ship or plane of ship
There is certain reduction.And traditional underwater exhaust the disadvantage is that, back pressure is big during exhaust, and then influence the hair of marine main engine power
Wave；The resistance of appendage increases, and reduces ship performance；Be vented the bubble that produces can with before ship and then being inhaled into propeller area,
Propeller will be made to produce cavitation erosion, cause its propulsive efficiency to substantially reduce.
The content of the invention
The purpose of this utility model seeks to reduce the exhaust resistance and the influence to ship power of ship gas extraction system,
A kind of rectifier type marine main engine underwater exhaust is provided and side of a ship device.
To achieve the above object, the rectifier type marine main engine underwater exhaust designed by the utility model goes out side of a ship device, including
Airduct body, the airduct body one end open is connected by flange with marine main engine exhaust outlet, the airduct body other end
Opening is stretched out in the outside of ship hull plate, and it is characterized in that：It is provided with arc shape on the outside of the ship hull plate
Cowling panel, the cowling panel is fastened on the outside of ship hull plate, and the cowling panel from stem direction to stern direction
Extend over to the airduct body other end open outer side.
Preferably, the cambered surface diameter of section of the cowling panel gradually increases from stem to stern direction.
Preferably, the airduct body supports the inner side for being arranged on ship hull plate by support webs.
Preferably, the support webs are provided with four, are circumferentially uniformly arranged along the airduct body outer wall.
The utility model has the advantage of：The side of a ship is gone out using the rectifier type marine main engine underwater exhaust designed by the utility model
Device, effectively reduces the back pressure that hull appendages resistance and current are produced to exhaust, and guiding main exhaust spreads to topside, it is ensured that row
Gas will not reduce propeller efficiency by the propeller suction positioned at hull bottom；The cambered design of deflector, effectively reduces exhaust
Resistance advantageously reduces main engine power extraneoas loss；The device is directly fixedly installed in Ship Structure simultaneously, to blast pipe or
Muffler provides certain rigid support, favourable to vibration reduction of ship noise reduction.
Brief description of the drawings

Fig. 2 is the A of Fig. 1 to structural representation；
Fig. 3 is the B-B cross section structure diagrams of Fig. 2.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments：
As shown in Figures 1 to 3, the rectifier type marine main engine underwater exhaust of the utility model design goes out side of a ship device, including airduct
Body 1, airduct body 1 is weldingly fixed on ship side structure inner side by support webs 3.Support webs 3 are provided with four, edge
The outer wall of airduct body 1 is circumferentially uniformly arranged.The joint of flange 2 that the welding of the one end open of airduct body 1 is provided with universal models is easy to
It is connected with marine main engine exhaust outlet, another end opening of airduct body 1 is stretched out in the outside of ship hull plate 5, the outside of ship hull plate 5
It is provided with the cowling panel 4 of arc shape, cowling panel 4 is fastened on the outside of ship hull plate 5, the cambered surface of cowling panel 4 is cut
Face diameter gradually increases from stem to stern direction, and cowling panel 4 is extended over to airduct sheet from stem direction to stern direction
Another end opening of body 1.During ship running, cowling panel 4 is made according to shipform, and rectification is carried out to hull surrounding fluid
With water conservancy diversion, negative pressuren zone effectively can be formed in air exit, reduce exhaust back pressure；Meanwhile, guiding main exhaust to hull outside
Spread side, it is ensured that exhaust will not be sucked by the propeller positioned at hull bottom, cause power loss.
