Description
Technical field:
The present invention relates to a kind of denoising devices of road traffic noise, and in particular to a kind of enhancing diffraction type sound barrier top noise reduction
Device.
Background technique:
With the raising of speed and the increase of the magnitude of traffic flow, thus bring traffic noise pollution also results in the very big weight of people
Depending on.In the various measures of noise control pollution, sound barrier is built in noise transmission path to block the mode of Acoustic Wave Propagation
It is efficient, economical due to having the characteristics that, at home and abroad obtain a large amount of application.In sound barrier construction, to the drop of sound barrier
Effect of making an uproar often requirement with higher can apply top denoising device to improve the noise reduction effect of sound barrier.Top noise reduction
Device is according to the difference of its de-noising mechanism, and different classes of, every other top noise reduction dress of type such as can be divided into absorbing sound type, interference-type
Its noise reduction feature and suitable environment are set.
Sound barrier application have passed through the development of decades, current stage, and most of sound barrier construction have all been abandoned single straight
Vertical form, often uses top structure-improved, but there are still following deficiencies: 1) considering from economy, safety etc., sound
The height of barrier nevertheless suffers from very big limitation, and under the premise of not increasing sound barrier whole height, noise reduction effect need
It improves；2) in the denoising device of sound barrier top used at present, its compact additional noise reduction effect of dimensional structure is more general, and
Preferably often structure is complicated for noise reduction effect, bulky to be applied to have strict demand to sound barrier size and weight
Environment；3) a part of sound barrier as road landscape, aesthetic effect do not cause enough attention.
Summary of the invention:
Technical effect of the invention can overcome drawbacks described above, provide the sound-screen of a kind of compact-sized, excellent noise reduction effect, good appearance
Hinder top denoising device.Overall profile is determined according to application environment, can be the beautiful contours profiles such as ellipse, heart.
The technical solution adopted by the present invention are as follows: a kind of enhancing diffraction type sound barrier top denoising device, including side plate, diffraction
Plate and lateral partitions；There is protrusion at the top of side plate and diffractive plate；Side plate and diffractive plate are symmetrical.
Further, both side plate is symmetrical, and positioned at the outermost of top denoising device, and side plate is curved slab, is convex to
Outside, side plate top have the protrusion for increasing diffraction loss.
Further, the quantity of the diffractive plate is 1 or 1 or more, has at the top of diffractive plate and increases diffraction loss
Protrusion, if the quantity of diffractive plate is 1 or more, diffractive plate is symmetrical.
Further, when the quantity of diffractive plate is 1 or more, cham-ber floor, diffractive plate, chamber are set between neighboring diffraction plate
Room bottom plate and lateral partitions form chamber structure, chamber roof opening.
Further, each protrusion profile at the top of side plate and diffractive plate is identical or not identical.
Further, the lateral partitions are surface plate, are arranged vertically with diffractive plate and side plate, and be alternatively arranged.
It further, further include drain aperture and mounting seat.
Beneficial effects of the present invention: including side plate, diffractive plate and lateral partitions；There is protrusion at the top of side plate and diffractive plate；
Side plate and diffractive plate are symmetrical；When with multiple diffractive plates, cham-ber floor is set between neighboring diffraction plate, cham-ber floor with
Diffractive plate and lateral partitions form open-topped chamber structure；Overall profile is determined according to application environment, can be ellipse, the heart
The beauty contours profiles such as shape.
Side plate is located at top denoising device outermost, is arranged symmetrically.Side plate is curved slab, is convex to outside, the profile of side plate
Shape can make sound wave generate biggish diffraction loss, and the protrusion at the top of side plate can further increase diffraction loss.Comprising one or
Multiple diffractive plates, diffractive plate top have protrusion, it is possible to increase acoustic wave diffraction loss in sound barrier top improves noise reduction effect.This top
Holding denoising device includes lateral partitions, and lateral partitions are vertical with diffractive plate and side plate, are intervally arranged, it is possible to increase top denoising device
Rigidity.Diffractive plate quantity can be increased under the premise of denoising device maximum width meets application requirement on top, it is better to obtain
Noise reduction effect.When diffractive plate number is greater than 1, diffractive plate is arranged symmetrically, and is arranged cham-ber floor between neighboring diffraction plate, diffractive plate,
The chamber structure of cham-ber floor and lateral partitions composition top end opening, cham-ber floor position is set according to Source Spectrum characteristic
Meter, can effectively improve specific middle low frequency noise reduction effect.For keep this top denoising device shape simple and beautiful and with application environment phase
Coordinate, the overall profile shape of this top denoising device can be designed according to application environment feature, can be ellipse, heart etc.
Different patterns.
Compared with prior art, it is an advantage of the invention that structure is simple, shape is simple and beautiful, can be applied to road, bridge
Etc. a variety of environment.By opposite side web wheel exterior feature and side plate and the design of the profile of diffractive plate top boss, sound barrier top is increased
Acoustic wave diffraction loss, reduces the dependence to sound barrier top denoising device width, so that top denoiser has smaller width
When still there is good noise reduction effect.The top denoising device is stablized without sound-absorbing material, energy free consumption, acoustical behavior.And have
Have the advantages that light-weight, the service life is long, appearance is symmetrically beautiful, maintenance is simple.
