Abstract
A sound absorption and noise reduction device of a compact fishing boat cabin ventilator consists of an outer frame, a silencing mechanism, a supporting crossbeam, angle iron, the ventilator, a cabin wall, glass fiber cotton and metal grids. The supporting crossbeam is fixed on the right side of the outer frame, the outer frame is used for fixing the total device onto the cabin wall via the angle iron, the silencing mechanism is mounted in the outer frame, the glass fiber cotton which is a silencing material is filled in the silencing mechanism, and the ventilator is disposed on the right side of the silencing mechanism. After the sound absorption and noise reduction device is mounted, tail gas in a cabin is discharged outwards via the ventilator and leads to the external after flowing through the silencing mechanism, when the tail gas flows through the silencing mechanism, the glass fiber cotton in the silencing mechanism is fluffy, and the glass fiber cotton which is in the shape of fluffy holes absorbs noises generated by flowing of the tail gas and operation of the ventilator, thereby eliminating the noise to a withstanding range of marine engine personnel.
Description
Technical field
The utility model relates to compact type fishing boat engine room fan sqouynd absorption lowering noise device, mainly is a kind of denoising device in the fishing boat cabin that the formed cellular eyelet of glass silk flosssilk wadding absorbs sound wave that utilizes, and belongs to ship machinery equipment field.
Background technique
For improving bad working environment in the fishing boat cabin, improve the working life of fishing boat main frame, ventilation plant is equipped by domestic a lot of fishery in affiliated fishing boat cabin, but the centrifugal or axial fan of equipment does not all have sound insulation in these fishing boat cabins at present, denoising device, relevant company makes an uproar as a result in the survey at 1 meter of fishing boat ventilator, and display noise can reach 110dB (A), the industrial region noise that is higher than the International Organization for Standardization regulation far away must not be higher than the recommended standard of 85dB (A), the noise that ventilator produces in the fishing boat cabin, have a strong impact on black gang's physical and mental health, the black gang often breaks away from post on duty, cabin because of hiding noise, cause that equipment failure takes place frequently in the cabin, had a strong impact on the safe and efficient navigation of fishing boat.Design one cover low cost of manufacture, working service easily the compact type fishing boat with the ventilator denoising device for reducing noise in the cabin, improve further that working environment has important practical value in the fishing boat cabin.
Summary of the invention
The purpose of this utility model provides a kind of compact type fishing boat engine room fan sqouynd absorption lowering noise device.
To be solved in the utility model is the problem of fishing vessel engine room fan sound insulation and noise reducing.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
Compact type fishing boat engine room fan sqouynd absorption lowering noise device, constitute by external frame, noise elimination mechanism, supporting traverse, angle steel, ventilator, machinery space bulkhead, glass silk flosssilk wadding, metal grill, supporting traverse is fixed on the right side of external frame, external frame is fixed on whole device on the machinery space bulkhead by angle steel, noise elimination mechanism is installed in the external frame, be filled with muffler material glass silk flosssilk wadding in the noise elimination mechanism, the right side of noise elimination mechanism is a ventilator.
Noise elimination mechanism is made of equally spaced metal grill of multirow and the muffler material glass silk flosssilk wadding that is positioned at metal grill; The right-hand isosceles triangle that is of metal grill, vertex angle theta is the 50-60 degree, and the length of metal grill is 0.4-1 rice, and the spacing between per two metal grills is 45-58mm, and the glass silk flosssilk wadding is fluffy eyelet-like.
After this device installs, when ventilator outwards discharges the tail gas in the cabin, tail gas leads to extraneous through noise elimination mechanism again, tail gas is through noise elimination mechanism the time, in-house glass silk flosssilk wadding is puffy owing to eliminate the noise, be the glass silk flosssilk wadding absorption exhaust gas flow of fluffy eyelet-like and the noise that the blower fan running is produced, thereby but noise reduction arrived in black gang's the tolerance range.
Advantage of the present utility model: this compact type sqouynd absorption lowering noise device has characteristics such as size is little, simple in structure, easy for installation, and excellent noise reduction effect has huge market prospects on coastal fishing boat, has also protected numerous fishermen's physical and mental health simultaneously.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-4, compact type fishing boat engine room fan sqouynd absorption lowering noise device, constitute by external frame 1, noise elimination mechanism 2, supporting traverse 3, angle steel 4, ventilator 5, machinery space bulkhead 6, glass silk flosssilk wadding 7, metal grill 8, supporting traverse 3 is fixed on the right side of external frame 1, external frame 1 is fixed on whole device on the machinery space bulkhead 6 by angle steel 4, and angle steel 4 specifications are 50 * 50mm; Noise elimination mechanism 2 is installed in the external frame 1, is filled with muffler material glass silk flosssilk wadding 7 in the noise elimination mechanism 2, the right side of noise elimination mechanism 2 is a ventilator 5, and ventilator 5 power are 4kw.
Noise elimination mechanism 2 is made of with the muffler material glass silk flosssilk wadding 7 that is positioned at metal grill 8 the equally spaced metal grill 8 of 8 row; The metal grill 8 right-hand isosceles triangles that are, vertex angle theta are 60 degree, and the length of metal grill 8 is 0.5 meter, 0.1 meter of width (as Fig. 4), and the spacing between per two metal grills 8 is 50mm; External frame 1 is square, is of a size of 1250 * 1250mm, and glass silk flosssilk wadding 7 is fluffy eyelet-like.
After this device installs, when ventilator 5 outwards discharges the tail gas in the cabin, tail gas leads to extraneous through noise elimination mechanism 2 again, tail gas is through noise elimination mechanism 2 time, because the glass silk flosssilk wadding 7 in the noise elimination mechanism 2 is puffy, be the glass silk flosssilk wadding 7 absorption exhaust gas flow of fluffy eyelet-like and the noise that ventilator 5 runnings are produced, thereby but noise reduction is arrived in black gang's the tolerance range, the actual measurement noise is about 50dB (A).
