Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Conjunction attached drawing is made a kind of specific embodiment of the present invention and is illustrated, and described embodiment is that a part of the invention is implemented
Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creativeness
All other embodiments obtained under the premise of work, belong to the scope of protection of the invention.
The present embodiment provides one kind wind condition test equipment wind column fairing, includes as shown in Figure 1：Pipeline fan 1
With pipeline 7,7 air inlet of pipeline is equipped with outer baffle liner 2, and the big opening end of outer baffle liner is connected with pipeline fan, outer baffle liner
Osculum end is connected with the big opening end of interior baffle liner 3, and outer baffle liner is equipped with gap 9 with interior baffle liner junction, is made into pipeline
Air-flow sub-fraction enters the annulus between pipeline and rectification straight tube by gap, since gap is smaller, so generate
Outer shroud wind column speed is relatively low；It is equipped with center flow regulating barrels 8 and rectification straight tube 6, the osculum of interior baffle liner in pipeline successively from the inside to the outside
End is connected with one end of rectification straight tube, and most of air-flow into pipeline is made directly to enter rectification straight tube at a high speed；Center flow regulating barrels
The one end communicated with interior baffle liner is tapered end face, and tapered end face is arranged in the osculum end of interior baffle liner completely, tapered end face
Aperture 10 is equipped at center, since center rectifying tube is located in rectification straight tube, it is whole that fraction air-flow can enter center by aperture
Flow cartridge, since orifice size is smaller, so wind speed is smaller, so the central air post speed generated is relatively low；At the air outlet 5 of pipeline
Equipped with injection fiaring cone 4, be conducive to exit wind column to center flow, reduce wind column and expand outwardly.Outer baffle liner and interior water conservancy diversion
Circle is connected by gap stent, and outer baffle liner is made to leave gap with interior baffle liner junction.Center flow regulating barrels lead to rectification straight tube
Cross small rack connection.Rectification straight tube is connected with pipeline by big stent.Gap stent, small rack and/or big stent are U-shaped or Z
Shape, general stent are welded on outer barrel, and inner cylinder is fixed with bolt and nut and stent, every to realize structure as defined in connection,
It is not limited only to rack form.
By adjusting the gap between outer baffle liner 2 and interior baffle liner 3, can adjust into pipeline 7 and center flow regulating barrels 8
Between annulus air volume；Diameter by the aperture for changing 8 end face of center flow regulating barrels, thus it is possible to vary into center
The air force of flow regulating barrels 8 makes to reach test requirements document in the wind speed for reaching each point at the section of air outlet predetermined distance
The concrete numerical value of wind speed, and section each point wind speed uniformity, gap 9 and aperture 10 can be specific according to different tests requirement
Design.To be further reduced noise, quieter material is equipped in inner-walls of duct.
During experiment, pipeline fan provides the air quantity of enough wind pressure to pipeline, and the air velocity that pipeline fan 1 sprays is very high,
The wind column of pipeline exit is easily expanded outwardly since circulation area becomes larger suddenly if pipeline is directly entered, and wind column dies down,
The present invention can effectively solve the problems, such as this, in use, after high-speed flow flows through outer baffle liner and interior baffle liner guiding, sub-fraction
Air-flow enters the annulus between pipeline and rectification straight tube by the gap between outer baffle liner and interior baffle liner, forms one
Outer shroud low velocity wind column；In addition the aperture of sub-fraction air-flow from center flow regulating barrels end face enters in the flow regulating barrels of center, forms one
Center low speed wind column；Most of air-flow enters the annulus between rectification straight tube and center flow regulating barrels, forms a high-speed loop
Shape wind column.This wind column is when leaving the outlet of rectification straight tube, since there is equidirectional stream in the outside of high-speed annular wind column and inside
Dynamic air-flow, does not generate vortex caused by negative pressure substantially, and high-speed annular wind column will not occur drastically in quick flow forward
Expansion, and partly to spreading outside to inside wind speed at entire wind column section can be made to tend to be uniform.Wind column when leaving air outlet because
The effect of injection fiaring cone outside air outlet, generates the effect of the jet flow to central axial direction, further fetters
Annular wind column expands outwardly.The annular wind column quickly flowed is in flow process, by smoothly inwardly or outwardly expanding,
Reach apart from air outlet 900cm apart from when, basically formed a solid circular wind column, and at this section, from
The axle center of wind column to the edge of wind column, the wind speed of each point is substantially uniform consistent, and error is less than ± 10%.
Pipeline fan power used in the present invention by original tens kilowatts, is reduced to 4.5 kilowatts, saves substantial amounts of electricity
Power resource.
The present invention allows airflow into pipeline and is divided into outer shroud low velocity wind column, center low speed wind column by setting gap and aperture
With annular high speed winds column, since there are outer shroud low velocity wind column and center low speed wind column on the outside of annular high speed winds column and inside, make height
The generation of vortex is reduced during fast flow forward, expansion drastically will not occur；Exit of the present invention is equipped with injection fiaring cone, uses
Air-flow is flowed to central axial direction at air port, has further fettered expanding outwardly for wind column；More than collective effect can make production
Raw wind column leaves the wind speed uniformity of the section each point at air outlet 900cm, and error is less than ± 10%, complies with standard regulation
Test method requirement；Wind column fairing provided by the invention is compact-sized, the small several times of the existing same category of device of volume ratio, one
As laboratory can just install and use；The power requirement of pipeline fan of the wind column fairing provided by the invention to using is small
In the several times of existing same category of device, substantial amounts of electric power resource is saved, while also just reduces the noise in laboratory.
