Description
Technical field
The utility model is related to noise reducing apparatus technical field, more particularly to a kind of silencing means.
Background technology
During summer peak of power consumption, the equipment in the hyperbaric chamber of transformer substation in city needs run for 24 hours.Equipment is run
During can produce heat, improve space temperature, and then on the normal using producing influence of equipment.In order to reduce in hyperbaric chamber
Temperature, on the wall of transformer substation high voltage chamber be provided with axial flow blower radiating.The air inlet of axial flow blower is connected with interior, axle stream
The air outlet of blower fan is connected with outdoor.But transformer and axial flow blower can produce very big noise in the process of running, seriously
Have impact on the normal life of surrounding resident.The noise that the noise produced in the hyperbaric chamber of transformer station is produced is mainly derived from tripartite
Face：1. the aerodynamic noise that the air inlet of axial flow blower and gas outlet produce by powerful air-flow；2. axial flow blower is in itself
The generation such as motor, casing mechanical oscillation noise；3. the electromagnetically noise of the generation such as transformer, motor.Therefore heat
While being shed by the air outlet of axial flow blower, noise spreads out also by the gas outlet of axial flow blower.
The content of the invention
In view of this, it is necessary to which providing a kind of hyperbaric chamber to transformer station carries out the silencing means of noise reduction.
A kind of silencing means, including silencing pipeline, silencing cotton, noise reduction guard, the silencing pipeline are fixed on axial flow blower
On the metope at place, the air inlet of silencing pipeline is connected with the blower fan gas outlet seal in the external world, and the gas outlet of silencing pipeline is set
Noise reduction guard, sets silencing cotton on the inwall of silencing pipeline, the size phase of the size of noise reduction guard and the gas outlet of silencing pipeline
Matching, so that noise reduction guard covers the air outlet of silencing pipeline.
Preferably, the silencing pipeline is square tube shape, and the air inlet of silencing pipeline is arranged on the side wall of silencing pipeline, disappears
The gas outlet in sound tube road is arranged on the bottom of silencing pipeline.
Preferably, the silencing pipeline is provided with screw hole, and screw hole is provided with accordingly on extraneous metope, and screw is passed through
Screw hole on silencing pipeline is fixed in the screw hole on metope, so that silencing pipeline is fixed on the metope in the external world.
Preferably, the upper end of the air inlet of the silencing pipeline to the vertical distance of the gas outlet of silencing pipeline for 800~
1000mm。
Preferably, the silencing cotton is pasted onto on the inwall of silencing pipeline.
Preferably, undulatory raised and groove is set on the silencing cotton, to strengthen the effect that silencing cotton absorbs noise.
Above-mentioned silencing means is applied to the noise reduction in the hyperbaric chamber of transformer station, and does not interfere with the drop in the hyperbaric chamber of transformer station
Make an uproar.Silencing means is set by the air outlet in axial flow blower, the noise in hyperbaric chamber can be effectively absorbed, while the noise reduction
Apparatus structure is simple, is easy to dismounting, therefore popularization degree is higher.
Brief description of the drawings
Fig. 1 is the structural representation of silencing means.
In figure：Silencing pipeline 1, silencing cotton 2, noise reduction guard 3.
Specific embodiment
Fig. 1 is refer to, silencing means includes silencing pipeline 1, silencing cotton 2, noise reduction guard 3, and the silencing pipeline 1 is fixed on
On metope where axial flow blower, the air inlet of silencing pipeline 1 is connected with the blower fan gas outlet seal in the external world, silencing pipeline 1
Gas outlet sets noise reduction guard 3, and silencing cotton 2, size and the silencing pipeline 1 of noise reduction guard 3 are set on the inwall of silencing pipeline 1
The size of gas outlet matches, so that noise reduction guard 3 covers the air outlet of silencing pipeline 1.
The silencing pipeline 1 is square tube shape, and the air inlet of silencing pipeline 1 is arranged on the side wall of silencing pipeline 1, hush pipe
The gas outlet in road 1 is arranged on the bottom of silencing pipeline 1.
Noise is refracted when being propagated by silencing pipeline 1, is internally formed in pipeline and reverberated, the silencing cotton of such inner-walls of duct
2 are just sufficiently buffered and are absorbed to it, to reach preferable noise reduction.
The silencing pipeline 1 is provided with screw hole, and corresponding on extraneous metope to be provided with screw hole, screw passes through hush pipe
Screw hole on road 1 is fixed in the screw hole on metope, so that silencing pipeline 1 is fixed on the metope in the external world.
The upper end of the air inlet of the silencing pipeline 1 to the gas outlet of silencing pipeline 1 vertical distance for 800~
1000mm。
The silencing cotton 2 is pasted onto on the inwall of silencing pipeline 1.
Undulatory raised and groove is set on the silencing cotton 2, to strengthen the effect that silencing cotton 2 absorbs noise.
Because the noise source in the hyperbaric chamber of transformer station is more various, therefore reduction noise is more difficult from noise source,
Therefore the utility model is using the propagation angle reduction noise from noise.Due to the noise major part in transformer substation high voltage chamber be from
The outlet of axial flow blower is outwards propagated and causes to disturb residents, therefore above-mentioned silencing means is set at the gas outlet of axial flow blower.So that
The noise spread out of in hyperbaric chamber is less than country《Standard of environmental noise of urban area》60 decibels between middle daytime, 50 decibels of noise of night
Value.While noise is reduced, the radiating in hyperbaric chamber will not be impacted；The silencing means simple structure, is easy to simultaneously
Dismounting, therefore popularization degree is higher.
