Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Embodiment 1:
As shown, a kind of mute Rainproof louver window in power station, including forms frame 1, metal blade 2, with type acoustical cotton 3, installation
Frame 4, sound-insulating felt 8, sound insulation disk 9 and acoustical cotton 10, the both ends transverse weld of the metal blade is in forms frame, metal
Blade is designed using cambered surface；It installs with type acoustical cotton metal blade lower surface；At the back side geometric center of forms frame 1 be equipped with every
One end of sound disk, sound insulation disk and mounting rack connects, and the other end of mounting rack is fixed on forms frame, the sound insulation circle
Disk closes on the side installation sound-insulating felt of metal blade, and acoustical cotton is installed in the other side of sound insulation disk.
Metal blade provided in this embodiment is by first segment cambered surface 201 and second segment cambered surface 202 in the tangent structure in point of contact 203
At first segment cambered surface and horizontal plane inclination angle are 0 °~45 ° gradual changes, and guide functions are significant, can effectively reduce windage；Second segment cambered surface
It is 45 °~55 ° gradual changes with horizontal plane inclination angle, it is larger by downward component on rain-impact to blade, it is conducive to improve water-resistant performance.
Inner wall connection type selects welding manner at left and right sides of metal blade and forms frame, reduces the noise that blade is generated by vibration.
To improve sound absorption and sound insulation effect, the type face with type acoustical cotton and metal blade 2 are consistent, with type acoustical cotton using highly dense
Acoustical cotton is spent, the processing of rounding angle is done with the horizontal edge of type acoustical cotton, reduces flow resistance.
Sound insulation disk 9 provided in this embodiment is metal material, installs sound-insulating felt 8 towards 2 side of metal blade, backwards
Acoustical cotton 10 is installed in metal blade side, and the material of three kinds of different surface densities is used in combination, sound insulation disk can be enhanced
Noise absorbent frequency range improves sound insulation and sound absorption effect.Mounting rack 4 is welded on sound insulation disk in cross uniform intervals,
Welded nut at the mounting hole of mounting rack, mounting rack are mounted on forms frame 1 by 4 sunk screws 11, sound insulation disk
Design can prevent the component noises such as the power station inner fan portion of directing out from radiating, and effectively promote shutter entirety noise reduction effect, because
The motor of blower is in axis line position, and sound insulation disk not will increase dramatically flow resistance.
The bottom of the forms frame 1 is set there are two drainage interface 7, and funnel type cone is processed on the top of drainage interface 7
Face, is easy to rainwater convergence, and the lower part machining internal thread of drainage interface 7 can be used for installing drainpipe, draining provided in this embodiment
Interface 7 can be converged and be oriented to the rainwater for crossing metal blade when that is, wind speed is greater than 18m/s under the conditions of extreme wind and rain
Discharge, prevents excessive rainfall from entering inside power station, influences power station work.For enhance rainwater collecting effect, in forms frame
Along one piece of water fender 12 of welding behind bottom, it is not higher by not less than 15mm and blade vertical height, forms catch basin.
Embodiment 2:
On the basis of embodiment 1, a kind of preferred embodiment is proposed, forms frame is using welding technique after molding, because of metal blade
Blade design is reasonable, and metal blade and frame or so inner wall are welded, to further decrease the vibration that power station vibration causes blade,
It is welded using column and all metal blade edges and frame or more inner wall is reinforced, the especially suitable larger-size blinds of this mode
Window, the quantity for reinforcing column can be designed according to specific length of blade and thickness, whole mechanical by above-mentioned measure shutter
Intensity is improved, and reduces the noise generated by metal blade vibration.The frame of forms frame installs rubber sheet gasket additional, improves blinds
The compactness of window and power station cabinet.For the sound absorption effect for improving shutter, the installation of metal blade lower surface is selected with type acoustical cotton
With high density acoustical cotton, to further decrease shutter flow resistance, acoustical cotton horizontal edge carries out the processing of rounding angle.Sound insulation disk is mainly right
The barrier of the external radiated noise of the power stations such as blower internal noise source, disk diameter is according to blower motor size and apart from sound insulation disk
Distance carries out matched design.For disk sound-insulating felt with a thickness of 2~3 times of rosette thickness, shape selects plate, acoustical cotton thickness
It is 4~6 times of rosette thickness or more, the preferred waveform of shape.
Working principle of the present invention:
A kind of mute Rainproof louver window in power station is mounted on power station at exhaust outlet, the transmitting of power station interior is effectively reduced
The noise that noise and high-speed flow generate.The design for reinforcing column improves shutter overall mechanical strength height, and blade is not easy to produce
Raw vibration noise.Metal blade blade profile takes into account water-resistant performance and low flow resistance, metal blade lower part adds using tangent double cambered surface designs
High density is filled with type acoustical cotton, improves sound insulation value.Sound-insulating felt and waveform acoustical cotton are installed in sound insulation disk front and back sides respectively, prevent
Only the component noises such as blower portion of directing out radiates；Water fender and drainage interface are installed in shutter frame lower part, can be when rainy
And wind speed be greater than 18m/s when discharge is oriented to the rainwater for flowing through blade.
The mute Rainproof louver window in power station provided by the invention, vane foil increase suction using tangent double cambered surface designs
Sound material, effectively improves the sound insulation value and aerodynamic quality of shutter, and rainproof effect is excellent.Sound insulation disk uses metal plate
+ sound-insulating felt+wave acoustical cotton composite structural design, further increases when not reducing louvre ventilation efficiency to noise
Isolation and assimilation effect.Mute Rainproof louver window has good sound-absorbing sound insulation, rainproof function and flow resistance is small, overall mechanical strength
The advantages that high.
The present invention has been described in detail with reference to the accompanying drawings, those skilled in the art can be according to upper
