Embodiment
In order to better understand technological scheme of the present invention, be also described in detail by reference to the accompanying drawings below by concrete case study on implementation:
As depicted in figs. 1 and 2, the three-dimensional stacked super-silent power supply of standard container of the present invention, comprise a steel structure square chest 1, air intake extended cavity 2, smoke-ejecting pipe 3, smoke-discharging noise elimination device combination 4, air exhausting soundproofing labyrinth 5, air draft extended cavity 6, diesel generating set 9, domestic oil tank 10, overall-in-one control schema switch cubicle 11, air intake noise elimination labyrinth 12, wherein: steel structure square chest 1 is designed to two dismountable independently standard container of satisfied extra large land traffic condition according to traffic condition, after arriving use scene, be assembled into entirety again, greatly convenient mobile and transport.These two standard container with the connection of bolt, shrouding and sealer, are respectively dynamic Control delivery casing 8 from bottom to up and air channel expansion noise reduction box 7 on junction surface.
Diesel generating set 9, overall-in-one control schema switch cubicle 11, domestic oil tank 10 and air intake noise elimination labyrinth 12 are fixed in dynamic Control delivery casing 8, this overall-in-one control schema switch cubicle 11 is control system and the electric power output system assembly of diesel generating set 9, comprise the various functions such as startup, protection, communication and unit electric power output main switch, it is the intermediate node connecting unit and load that electric power exports main switch; One is also provided with by the domestic oil tank 10 of high-pressure oil pipe 13 to diesel generating set 9 fuel feeding in dynamic Control delivery casing 8.
Dynamic Control delivery casing 8 and air channel expansion noise reduction box 7 surrounding inwall are all equipped with two kinds of density sound-absorbing materials and zinc-plated punching steel plate; Ceiling board is equipped with sound-absorbing material and zinc-plated punching steel plate.The perfect cooperation of punching steel plate and high-efficiency sound-absorbing material resembles countless sound piston, and when noise impacts sound absorbing material through punching steel plate aperture, as promotion piston movement, sound wave causes the vibrations of air in sound-absorbing material hole and fiber fines.Due to friction and viscous resistance, the kinetic energy a part of noise energy being become sound piston consumes, thus decreases the outside propagation of a part of noise.
The end face double door of dynamic Control delivery casing 8 and control export double door and are designed to noise-reducing door, add rubber strip sealing; End face double door lays high-efficiency sound-absorbing rock wool, and nexine lining is with zinc-plated punching steel plate; The AD of both sides, the most easily reveals noise, is designed to convex door, adds rubber strip sealing, reaches outdoor with the noise forming dual sound lock effect partition diesel generating set 9 by crack between a door and its frame.
Smoke-ejecting pipe 3, smoke-discharging noise elimination device combination 4, air intake extended cavity 2, air exhausting soundproofing labyrinth 5, air draft extended cavity 6 are fixed in air channel expansion noise reduction box 7.Smoke-discharging noise elimination device combination 4 is combined by the ripple vibration damper be connected on diesel engine 14, a dissipative muffler and a reactive muffler, this reactive muffler is combined by the some sections of difform pipelines connected successively and resonant cavity, by means of pipeline section and shape change and the acoustic impedance caused does not mate produced reflection and interference effect, reach the object of attenuate acoustic noise.Dissipative muffler is made up of the sound absorption rock wool of zinc-plated punching pipe and interlayer, and when noise impacts sound absorbing material through punching steel plate aperture, just as promotion piston movement, sound wave causes the vibrations of air in sound-absorbing material hole and fiber fines.Due to friction and viscous resistance, the kinetic energy a part of noise energy being become sound piston consumes, thus decreases the outside propagation of a part of noise.
The vertical resistance noise reduction sheet that air intake noise elimination labyrinth 12 and air exhausting soundproofing labyrinth 5 arrange by multi-disc lateral separation is formed, and forms 1-3 extended cavity expanding when noise reduction box 7 connects with air channel; Owing to arranging expansion cavity, making noise producing the unmatched reflection of acoustic impedance and interference effect through extended cavity expansion again after vertical resistance noise reduction sheet decay, reaching the object that noise is decayed again; Simultaneously owing to entering, the elongation in air draft path, make noise Natural Attenuation in the process of releasing, add noise reduction.Electric-powered shutter can be installed in the expansion rear end of noise reduction box 7, air channel and both sides, for controlling into, air draft direction.
Smoke-ejecting pipe 3 is connected to expansion noise reduction box top, air channel on smoke-discharging noise elimination device, and stretches out top.Smoke-ejecting pipe 3 is connected with gasket seal with flange; High-pressure oil pipe 13 is connected by male and fomale(M&F) SEALING FITTING; Cable busbar connects.Structural design has taken into full account manufacturability and the reliability of steel structure square chest 1 dismounting.
The three-dimensional stacked super-silent power supply of standard container of the present invention, when land transportation or sea-freight due to the restriction by traffic condition, can first be disassembled into the standard container that can meet transportation demand, after arriving use scene, then be assembled into entirety, greatly save cost of transportation.In addition, adopt the technological means such as damping, sound absorption, sound insulation and noise elimination, restriction vibrations and sonic propagation of making an uproar, guarantee under the condition meeting diesel generating set cooling channel and exhaust back pressure allowable, namely, under ensureing the prerequisite that unit full power exports, super-silent working effect is reached.
Technician in the art will be appreciated that, above case study on implementation is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of above-mentioned case study on implementation, modification.
