Abstract
The utility model discloses a three -dimensional pulsation anemoscope fixing device of wind -tunnel, characterized by: including chassis, horizontal pole, montant and two connecting pieces, the montant install on the chassis, the horizontal pole pass through connecting piece fixed mounting on the montant, horizontal pole perpendicular to montant, be equipped with a connecting piece on the horizontal pole for the three -dimensional pulsation anemoscope of installation. The utility model discloses say on the whole to minimum economy drops into, acquires experimental wind speed and turbulence scale that the research institute need need most, and simple structure, and shared space is little, and is with low costs, and easily control and theory of operation are clear, and the actual effect is good.
Description
Technical field
The utility model belongs to technical field of civil engineering, relates to a kind of wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation specifically.
Background technology
Wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation is that a kind of height by adjusting connector accurately obtains the wind speed at wind tunnel test desired height place and the test unit of turbulivity.For accurate perception wind is to the effect of structure, general structure needs to carry out wind tunnel test, and wind tunnel test needs the wind speed and the turbulivity that are obtained test desired height place by three-dimensional fluctuating wind speed instrument.The domestic wind-tunnel investigation to engineering structure is started late, but research direction has perspective very much, accurately to obtain wind speed and the turbulivity at wind tunnel test desired height place, be necessary development three-dimensional fluctuating wind speed instrument stationary installation, and the research device of similar products at home and abroad is less, so exploitation the technology has the important and meaning of reality.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides the wind-tunnel three-dimensional fluctuating wind speed instrument that a kind of structure is simple, cost is low stationary installation.
The technical solution adopted in the utility model is: a kind of wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation, comprise chassis, cross bar, montant and two web members, described montant is arranged on chassis, and described cross bar is fixedly mounted on montant by web member, and cross bar is perpendicular to montant; Cross bar is provided with a connection piece, for installing three-dimensional fluctuating wind speed instrument.
In above-mentioned wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation, described web member comprises contiguous block and two holding screws, described contiguous block is provided with cross bar hole and montant hole, cross bar hole is vertical with montant hole, contiguous block is respectively equipped with a set screw hole corresponding to cross bar hole and montant hole, in two set screw hole, is equipped with holding screw.
In above-mentioned wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation, the material that described montant and cross bar adopt is iron.
In above-mentioned wind-tunnel three-dimensional fluctuating wind speed instrument stationary installation, described chassis is rounded, and the place of bottom centre on chassis is provided with circular groove.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is said on the whole, and with minimum economic input, obtaining research institute needs the test wind that needs most and turbulivity, and structure is simple, and institute takes up space little, and cost is low, is easy to control and principle of work is clear, and actual effect is good.
