Description
Technical field：
The utility model belongs to wind speed collecting device technical field in wind-tunnel, more particularly to a kind of vertically adjustable multiple spot is seen
The horizontal wind speed instrument support of survey.
Background technology：
Wind-tunnel is most widely used instrument in aerodynamic studies and experiment, and its essence and core can exactly pass through
Artificially generated and control air-flow simulates the flowing of the gas around object and feature, and can measure effect of the air-flow to object and
A kind of pipe-like experimental facilities platform of physical phenomenon is observed, it is to carry out that aerodynamic experiment is the most frequently used, maximally effective instrument.
Interior has been moved to equivalent to by the test site in field, there can be controllability strong, repeatability is high by manual control airflow field
The characteristics of, therefore, wind-tunnel widely applies to about aerodynamic research and all kinds of Wind Engineering, surroundings wind field, prevented now
In research and test that wind fixes the sand etc..Mainly entered in wind-tunnel by the equipment of mensurable wind speed to obtain the air speed data of air-flow
And analyzed and researched.The use of the method for the most traditional measure wind speed is exactly come determination test object with Pitot tube in wind-tunnel
The wind speed on periphery, and then study its Field Characteristics.With the development of science and technology, also it is used for surveying now with anemobiagraphs such as hot line, hotting masks
Determine wind speed control.During the flow field on measure object periphery, Pitot tube can be used alone measure wind speed, can also be multiple groups
It is used in combination.Because required environment is controllable, it is not necessary to the advantages that carrying out large-scale experimental study and efficiency high in the wild,
Wind-tunnel is increasingly taken seriously in agricultural protection forest configuration, sandstorm prophylactico-therapeutic measures, new material of checking winds and fixing drifting sand research and development etc.,
As essential research equipment platform.Currently, all it is by multiple skin supports with vertical support frame mostly in blowing sand wind tunnel
Pipe combines using measure wind sand environment wind speed control.4-10 Pitot tube is combined into a vertical plane by support to survey
It is fixed, to obtain the wind velocity gradient minute in the vertical direction of this point at a point position vertical direction different distance during measure
Cloth.This assay method can disposably obtain the wind speed numerical value of point position different height under same wind friction velocity.Such as
Fruit has multiple measuring points, then is determined after each measuring point is moved one by one, finally arranges data and obtains wind speed control.For example,
Configuration experiment is carried out to shelter-forest in wind-tunnel, often just has the model uniformly configured, or the configuration of more homogeneous forest belt, just
Need the space larger to allocation models inside and periphery one by one site carry out wind speed wind field measure；Also for example, in wind-tunnel
Carry out all kinds of different sand-protecting barriers to check winds and fix drifting sand the research of performance, the configuration of sand-protecting barrier model configures if ribbon, it is necessary to sand-protecting barrier
The wind speed numerical value of inside and outside portion space different loci is acquired, and could obtain the characteristic of space flow field, etc. of entirety, these
Wind tunnel experiment is the configuration of more single model, needs to be measured point by point using above-mentioned vertical support frame measure wind speed, more
It is cumbersome, also labor intensive and muscle power.For example, carrying out the uniform allocation models in different forest belts in wind-tunnel, or carry out different sand
Hinder research of wind-break potency etc., in order to obtain the wind speed control of a certain height in horizontal direction, if allocation models is 1m X 1m, survey
Point distance be 0.1 X 0.1m, then determine site at least 100 points, using above-mentioned vertical support frame be measured then each put by
One needs to move measure, so relatively complicated, inefficient.Therefore, how using a kind of faster method, efficiently obtain
The air speed data of each point is obtained, and studies its Field Characteristics as work important in blowing sand wind tunnel.
The content of the invention：
Technical problem to be solved in the utility model is：There is provided can be with horizontal direction and simultaneously in a kind of wind tunnel test
The support of multi-site determination wind speed, the wind speed numerical value in multiple measure sites of sustained height on horizontal plane can be obtained simultaneously, is overcome
Asynchronism of the vertical support frame in sustained height wind speed numerical process is determined, needs to move one by one, and measure is cumbersome, test effect
