Abstract
It the utility model is related to small-sized wind tunnel experimental rig technical field, there is provided a kind of easy flow tunnel testing device.Flow tunnel testing device is mainly made up of array fan, dividing plate, turning vane in corner, anemobiagraph, wind speed display, illuminating lamp and housing.Installation with semi-closed designs, and experimenter can be quickly installed or take out by experimental rig and quickly carry out wind tunnel test, and experimenter can also be clearly observed wind tunnel test situation at that time during experiment.And using reverse-flow type to design, device can reduce the interference to external environment during wind tunnel test is carried out.
Description
Technical field
It the utility model is related to small-sized wind tunnel experimental rig technical field.
Background technology
Wind-tunnel is most popular instrument in aerodynamic studies and experiment.The Wind Engineering of colleges and universities, civil engineering, vapour
The specialty such as turner journey, mechanical engineering relates to the correlation test research of wind-tunnel.And most of simple wind tunnel tests and it is not required to
Flow tunnel testing device that will be too complicated and expensive, with greater need for it is a kind of it is simple, effectively, the experimental rig of low cost, in favor of experiment
It is quick to carry out and reduce experimentation cost.
The content of the invention
The utility model provides a kind of semiclosed return circuit wind tunnel experimental rig.
Device uses this closed design, can be quickly installed or take out by experimental rig, and quickly carries out wind-tunnel examination
Test, experimenter can also be clearly observed wind tunnel test situation during experiment, and use reverse-flow type to design, and can enter
Interference is not almost produced during row wind tunnel test to external environment.
Flow tunnel testing device is mainly by array fan（1）, dividing plate（2）, turning vane in corner（3）, anemobiagraph, wind speed display
（4）, LED illumination lamp and housing（5）Deng composition.Described wind-tunnel includes fan section, stable section（B）, test section（A）, reflux section
（C）.Fan section is located at the right front of device, and to produce airflow portion, this section of array installs a number of fan, fan electromotor
Controlled by DC speed regulator, wind-force size can be controlled by speed regulator；Stable section（B）On the left of fan section, stabilization is played
Airflow function, it is one section of linear pattern passage；Test section（A）Immediately ahead of device, for laying by experimental rig, test section
（A）Top is equipped with LED, plays illuminating effect, is easy to experimenter to observe；Reflux section（C）Positioned at the left side of test section and device
Rear side and right part, play reflux airflow effect.Thus, airflow circulating is formed, and the flowing of air completely can be in device
Inside is carried out, and is not required to supplement from external environment, also wake flow will not be emitted into external environment.
The present apparatus is simple in construction, and in use, device does not almost produce interference to external environment.With experiment side
Just the features such as, response is fast, low cost.
The present apparatus has larger application prospect in small-sized wind tunnel experiment field.
Brief description of the drawings
Fig. 1 is the overall structure diagram of experimental rig.
Fig. 2 is the top view of experimental rig.
In figure：1 is array fan, and 2 be dividing plate, and 3 be turning vane in corner, and 4 be wind speed display, is test section in the range of A,
It is steady flow segment in the range of B, is reflux section in the range of C.
Embodiment
Device is integrally substantially divided in two parts, and centre is by dividing plate（2）Distinguish, dividing plate（2）Play device girder simultaneously
Supporting role.Array fan（1）It is arranged on by a number of fan by bolt with array way on vertically-mounted frame.Fan
Motor parallel is connected to speed regulator, and speed regulator is connected to rectifier power source, and air-flow velocity size is by adjusting speed regulator in wind-tunnel
Control.Test section（A）For open area, mask is not set, this section is by experimental rig placement and taking-up.Wind-tunnel interior air-flow turns
Turning vane in corner is provided with angle（3）, play generation separation when avoiding airflow passes turning and cause to flow uneven and energy loss
Effect.Housing（5）It is made up of some pieces of masks, is easy to dismount.Housing（5）Mainly by upper mask, bottom mask, left and right mask and
Mask forms afterwards.Mask material can be force fit plate or aluminium sheet.In steady flow segment（B）In be provided with anemobiagraph, wind-tunnel can be detected at that time
Wind speed, air speed data pass through the wind speed display on device（4）Display.
Claims (2)
1. a kind of semiclosed return circuit wind tunnel experimental rig, including：Array fan（1）, dividing plate（2）, turning vane in corner（3）, wind
