Description
Technical field
The utility model relates to a kind of noise reduction engine-room fan room structure of engine-room fan room, particularly a kind of steamer of steamer.
Background technology
Steamer refers to the ship promoting with mechanical engine, multiplex iron and steel manufacture.The power pack section of modern steamer is one group of turbine engine (Turbine engine, or often referred to as Turbine).Turbine engine is that a kind of parts that utilize rotation pass the engine type that draws kinetic energy in its fluid certainly, and its whole progress of work all can be attended by obvious noise, and noise volume generally can reach 105 decibels of left and right.Therefore, when defect appears in the integral layout of steamer, while causing the engine-room fan room in certain cabin on this ship and the power pack section of steamer distance too to approach, the noise producing when the above-mentioned middle work of the turbine engine as steamer power part will be brought in engine-room fan room along with sea wind, thereby being mixed into a step with the noise that in engine-room fan room, negative-pressure air fan work itself produces enters in steamer cabin, this above-mentioned situation can badly influence the daily work and rest of staff in cabin, and even more serious words also can have influence on staff's physical and mental health.Therefore, we think and are necessary that the engine-room fan room structure to existing steamer improves.
Utility model content
The purpose of this utility model is the noise reduction engine-room fan room structure that a kind of steamer is provided in order to solve above-mentioned the deficiencies in the prior art.Above-mentioned noise reduction engine-room fan room structure can reduce the noise that enters cabin.
To achieve these goals, the noise reduction engine-room fan room structure of the designed a kind of steamer of the utility model, comprise engine-room fan house-owner body and negative-pressure air fan, on above-mentioned engine-room fan house-owner body, offer air intake window and air outlet, negative-pressure air fan is arranged in engine-room fan house-owner body, and corresponding with the air outlet on engine-room fan house-owner body, on the air intake window of above-mentioned engine-room fan house-owner body, palisade is placed with more than two acoustical panels.
As preferably, above-mentioned two above acoustical panels are that parallel equidistant is arranged each other, and wherein said acoustical panel is rectangular shape.Taking the width of engine-room fan house-owner body upper air inlet window as 3 meters for instance, above-mentioned in gap width between adjacent two acoustical panels can be probably 0.13 ~ 0.15 meter, the thickness of every acoustical panel can be 0.1 ~ 0.12 meter.Through observed data support, the engine-room fan house-owner body structure of said structure can be directly by the reducing noise to 85 decibel of 105 decibels.
In order not take the space outerpace of hull, above-mentioned middle acoustical panel entirety is extended toward the inner side of air intake window, between the medial surface of acoustical panel and the aftbulkhead of engine-room fan house-owner body, is formed with air intake runner simultaneously.
In said structure, on the air intake window of engine-room fan house-owner body, palisade is placed with more than two acoustical panels, make outside wind negative-pressure air fan produce negative pressure effect under or can be unobstructed be inhaled in engine-room fan house-owner body.Meanwhile, the existence of acoustical panel can suck part noise in wind to weakening again, thereby makes the utility model provide engine-room fan room structure under the prerequisite of the normal ventilation function of guarantee, can realize again the object of noise reduction.Be how can be by the reducing noise in wind as for above-mentioned middle acoustical panel, this be the conventional rudimentary knowledge in correlative technology field.Therefore applicant is just seldom described in detail at this.
In order to make can to realize and closing on the air intake window of above-mentioned engine-room fan house-owner body, on the air intake window of above-mentioned engine-room fan house-owner body, being also provided with can folding forms, and this can folding forms be positioned at the outside of acoustical panel.In above-mentioned, can preferentially select louver by folding forms, because louver can not take hull space equally.
In order to promote the fluency of wind flow in the Ventilator Room main body of cabin, in above-mentioned, between more than two inside lower end of acoustical panel and the forward bulkhead inside face of engine-room fan house-owner body, be jointly connected with deflecting plate.
For convenient, the wind sucking through negative-pressure air fan is directly carried to cabin, on the aftbulkhead inside face of above-mentioned engine-room fan house-owner body, be connected with tubulose air channel, the bottom of the corresponding negative-pressure air fan of one port in this tubulose air channel, and be connected and sealed between the two, air outlet on the corresponding engine-room fan house-owner body of its another port, and both are connected and sealed equally.
The noise reduction engine-room fan room structure of a kind of steamer that the utility model obtains, it,, outside the normal ventilation function in guarantee engine-room fan room, can realize again noise reduction object.Thereby make to adopt the steamer of above-mentioned noise reduction engine-room fan room structure, even if having cabin, cabin on its hull is to be positioned at by steamer power pack section, its cabin interior does not have too large noise yet, and what staff still can be relatively quiet carries out routine in cabin.It is reasonable that while the utility model also possesses space layout, good some advantages such as grade of working stability.
