Description
Technical field
The utility model relates to a kind of high-power power-equipment (as high-power diesel engine, diesel-driven generator etc.) very noisy noise reduction technology, particularly high-power power-equipment noise reduction mobile field camp.
Technical background
Under field construction operating conditions such as oil field, colliery, often to use power-equipments such as high-power diesel engine, diesel-driven generator, gasoline engine.It is their strong noise that these high-power power-equipments have individual common drawback and technical barrier.For example, supporting Ka Te among the rig ZJ40LDB of oil drilling engineering use. that reins in diesel-driven generator AT3512B, and test shows during this machine operate as normal, maximum noise value are 115dB (A); The maximum noise value is 107dB (A) during the most frequently used VOLVO300KW diesel-driven generator operate as normal of oil drilling engineering.
At present, very noisy equipment such as high-power power that is to say in the noise abatement of fixed operation place to obtain paying attention to and handling fixed operation place noise problem generally being taked carry out noise abatement in fixed-site (as factory building etc.).To the field work situation, owing to high power strong noise equipment belong to move construction, generally away from the residential block, administer reason such as difficulty, nearly all do not carry out effective noise reduction process, or do not handle at all.The noise abatement of field construction belongs to the initial starting stage at home.Traditional way of passing through to fix a silencer for the powerful device exhaust opening can not effectively solve the very noisy problem, above-mentioned way can only play very limited noise reduction effect, because the power-equipment propagation of noise is three-dimensional, omnibearing, can't realize whole noise reduction by control to a part.
Along with The development in society and economy, the state's laws rules are administered noise pollution and are proposed more and more stricter requirement, as: regulation among the standard GB 21-2002 " Design of Industrial Enterprises sanitary standard ", machine room instrumental observation position noise maximum permissible value noise figure is 85dB (A); Do not reach the place that national standard requires, when noise figure was 96dB (A), the time of staff's every workday contact noise can not be above 2 hours; When noise figure was 99dB (A), the time of staff's every workday contact noise can not be above 1 hour.So, must control effectively to strong noise pollution.
Under strong noise environment, work, have a strong impact on staff's physical and mental health, disturb living environment.Country controls noise pollution by legislation for this reason.
Summary of the invention
The purpose of this invention is to provide a kind of high-power power-equipment noise reduction mobile field camp, be able to fine control, satisfy national requirements for environmental protection to guarantee the very noisy that the high-power power-equipment of field construction produces, and economical and practical, firm reliable, convenient removal.
The utility model is to realize like this, design a kind of high-power power-equipment noise reduction mobile field camp, which comprises at least the sound insulation board house body 1 of the high-power power-equipment of sealing, sound insulation board house body 1 has air intake 4, air outlet 6 and soundproof door 3, sound proof window 17, it is characterized in that: air intake 4 is noise elimination grid 5, air outlet 6 is noise elimination well 9, air outlet 6 seals into the noise elimination road by soft material 8 structures with high-power power-equipment air outlet, and the noise elimination road vertically is arranged with the noise elimination well 9 of acoustical board 16 formations to the interface channel on top.
Described air intake 4 has noise elimination grid 5, and air outlet 6 has noise elimination well 9.
Described sound insulation board house body 1 has two glass from sound proof window 17, double-deck glass between form angle.
Form angle between the described double-layer glass at 2 degree～15 degree.
Described sound insulation board house body 1 is followed successively by metal sheet, sheet material 12, cavity 13 structures, acoustical board 16, balustrade exterior panelling 15 from outside to inside.
Described air outlet 6 has rain cover 7, and acoustical board 16 is housed in the rain cover 7.
Described noise elimination well 9 is passages that high-power power-equipment air outlet is connected with space outerpace.
Described soft material 8 is cloth or chemical fibre, cotton spinning.
The utility model has the advantages that: because air intake is opposite with high-power power-equipment air outlet, air outlet seals into sound channel by soft material with high-power power-equipment air outlet, and sound channel vertically is arranged with the noise elimination road (noise elimination well) that acoustical board constitutes to top.Said structure can guarantee that the smooth and easy while of cold and hot circulation of air can reduce noise.The mobile field camp overall structure cooperates installs soundproof door, sound proof window, guarantees to use easy to operate.The mobile field camp wall body structure calculates technical performance advanced person through optimizing.High-power power-equipment mobile field camp wall body structure is followed successively by metal sheet, sheet material, cavity structure, acoustical board, balustrade exterior panelling from outside to inside.By the mobile field camp overall structure being optimized design and selection, actual measurement shows that the type mobile field camp can propagate into former high-power power-equipment extraneous noise figure and reduce 20dB (A)---30dB (A).Be in when high-power power-equipment is moved in the sufficient environment of turnover smooth and easy, the cold and hot interchange of air of wind, can guarantee the equipment operate as normal for a long time, mobile field camp is installed easy to make, economical and practical.
