Abstract
The invention discloses a telescopic wind duct for a wind tunnel. The wind duct at least comprises two big wind ducts and one small wind duct; the two big wind ducts are movably connected by the small wind duct; the telescopic wind duct is specifically characterized in that two end parts of the small wind duct are respectively stretched into the big wind ducts; the external wall of the small wind duct is matched with the internal walls of the big small ducts in a sliding manner; the end parts of the big wind ducts are provided with rubber rings; chutes are arranged at intervals on the external wall of the small wind duct; and rollers are arranged at the bottoms of the big wind ducts. According to the telescopic wind duct for the wind tunnel, the heavy overall wind tunnel is divided into a plurality of conveniently moved telescopic wind ducts, so that the length of the telescopic wind duct can be flexibly changed; moreover, the big wind ducts are provided with the rollers, so that each part can be moved conveniently; and the parts can be self-assembled according to the requirements, so that the wind tunnel is applicable to multiple experimental tasks.
Description
Technical field
The present invention relates to the equipment of aerodynamics experiment, relate in particular to a kind of Telescopic air duct that is used for wind-tunnel.
Background technology
21 century, scientific and technological level improved constantly as the new period of human development, and each item technology of making rapid progress has all had the development of comprehensive high speed.And aerodynamics as one with human closely bound up subject, its research has very significant meaning to test direction.Carry out aerodynamic research; Just need with wind-tunnel platform simulation atmospheric environment; Wind-tunnel for aerodynamic development test provides required flow field, is the modern science technology as a basic equipment of aerodynamics experiment; Especially the product of aerodynamics, fluid mechanics develop rapidly, the birth of wind-tunnel makes a large amount of aerodynamic experiments be able to smooth completion.People in modern has obtained utilization widely with all kinds of wind-tunnel of sophisticated technologies means developments at Aero-Space, rocket-powered missile, environmental pollution, auto industry, education experiment, numerous areas such as build a bridge.
In order to satisfy the demand of scientific domain development, size is different, the different wind-tunnel of type begins the Large scale construction in countries in the world.Traditional wind-tunnel generally adopts Design Modes such as diffuser, stable section, transition section, contraction section and turning.For each colleges and universities of the whole nation, the scientific research project of more and more scientific research projects all need be used wind-tunnel, builds traditional wind-tunnel simultaneously and need spend great amount of manpower and material resources., most scientific research project is not high for the requirement of wind-tunnel, and because the most of colleges and universities of the restriction of manpower and materials all hope the multiple experimental duties of wind-tunnel completion.
Small-sized now wind-tunnel is in the face of different experimental duties the time, and the length of wind-tunnel each several part is all fixed usually, when different experimental duties, needs to change the wind-tunnel of different length, operate both flexible inadequately, again can not the multiple experimental duties of simultaneous adaptation.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of prior art, a kind of flexible operation is provided, can adapts to the Telescopic air duct that is used for wind-tunnel of multiple experimental duties.
The present invention realizes through following technical proposals:
A kind of Telescopic air duct that is used for wind-tunnel, Telescopic air duct comprise two big air ducts, a little air duct at least, flexibly connect through little air duct between two big air ducts.
Flexibly connecting through little air duct between said two big air ducts, specifically is that two ends of little air duct are stretched into respectively in the big air duct, and the outer wall of little air duct is slidingly matched with the inwall of big air duct.
The end of said big air duct is provided with rubber ring, and the outer wall of said little air duct is arranged at intervals with skewed slot.
Roller is equipped with in the bottom of said big air duct.
Compared with prior art, advantage of the present invention and effect are:
The present invention is divided into the Telescopic air duct that a plurality of convenience move to heavy wind-tunnel integral body; The length of flexibly changing Telescopic air duct, and the strong wind wound packages has roller, and various piece is convenient to be moved; Can individual partially self be assembled according to demand, thereby make wind-tunnel can adapt to multiple experimental duties.
End at big air duct has increased rubber ring, and after Telescopic air duct was adjusted to the experiment Len req, rubber ring can snap in the skewed slot on the little air duct, has increased the sealing property of joining place between big air duct and the little air duct, makes experimental data more stable.
The present invention is simple and quick, and construction cost is low, and strong innovation can effectively improve the wind-tunnel scope of application, for the multi-usage design of wind-tunnel from now on provides important reference and foundation with use.

Fig. 1 is the structural representation after the Telescopic air duct elongation according to the invention.
Fig. 2 is the structural representation after the Telescopic air duct indentation according to the invention.
Embodiment
Below in conjunction with specific embodiment the present invention is done further concrete detailed description the in detail.
Embodiment
Like Fig. 1, shown in Figure 2, the present invention is used for the Telescopic air duct of wind-tunnel, and said Telescopic air duct comprises at least between two big air ducts 1,2, two big air ducts 1 of little air duct and flexibly connecting through little air duct 2.Specifically can two ends of little air duct 2 be stretched into respectively in the big air duct 1, the outer wall of little air duct 2 is slidingly matched with the inwall of big air duct 1, and it is flexible that little air duct 2 can be free to slide in big air duct 1.
The end of said big air duct 1 is provided with rubber ring 4, and the outer wall of little air duct 2 is arranged at intervals with skewed slot.
Length according to the wind-tunnel of experiment needs; With little air duct 2 by pulling out outward in the big air duct 1; After Telescopic air duct was adjusted to the experiment Len req, rubber ring 4 snapped in (not shown) in the skewed slot on the little air duct 2, rubber ring 4 both increased in the big air duct and the sealing property of joining place between the little air duct; Make experimental data more stable, played the effect of location Telescopic air duct again indirectly.
After experiment finishes; Take out the rubber ring 4 that is stuck in the skewed slot; Little air duct 2 is extracted out from the big air duct 1 of back one-level and it is directly filled in big air duct 1 the inside; Remove the braking of roller 3 then, can it be moved to other local corners saving breadboard space like this, and also make things convenient for the transportation of wind-tunnel.Reach portable effect.
Telescopic air duct of the present invention, length that can be required according to requirement of experiment increases the number of combinations of big air duct 1 and little air duct 2.As: three big air ducts 1 and two little air ducts 2 constitute a combination; Four big air ducts 1 and three little air ducts 2 constitute a combination etc.Also have multiple array mode not list one by one.
As stated, just can realize the present invention preferably.
The foregoing description is merely preferred implementation of the present invention; But embodiment of the present invention is not restricted to the described embodiments; Other are any not to deviate from change, the modification done under spirit of the present invention and the principle, substitute, combination, simplify; All should be the substitute mode of equivalence, be included within protection scope of the present invention.
