By the ADV moving device, the probe of the ADV can be accurately fixed at any position of the water channel; and a testing error can be effectively reduced.
Description
Technical field
The present invention relates to a kind of acoustic Doppler current meter (ADV) mobile device, particularly a kind of ADV mobile device that is applied to hydraulics or the measurement of rate of flow of fluid mechanics laboratory tank.
Background technology
Flow velocity is the important parameter in the hydrodynamics; The researcher has developed multiple current meter for measuring flow velocity; Acoustic Doppler current meter (Acoustic-Doppler Velocimeter wherein; Hereinafter to be referred as ADV) with advantages such as it are little to the current interference, measuring accuracy is high, easy and simple to handle, be widely used in fields such as laboratory tank, open-air river and ocean.
ADV is a kind of instrument of measuring the single-point flow velocity; Can measure water the three-dimensional velocity of stream; Its principle is based on the theory of Doppler effect (Doppler effect), and promptly when wave source and observer had relative motion, the ripple that the observer receives changed frequently; Frequency of sound wave uprises when sound source is shifted to the observer, step-down when sound source outlying observation person.ADV mainly is made up of three parts: measure probe, signal conditioner, signal processor.Measure probe and form by three receiving transducers and a transmitting probe, three receiving transducers be distributed in the transmitting probe axis around, the angle between them is 120 °.Transmitter is launched a branch of long and narrow ultrasound wave in water, run in the water particulate perhaps " scatterer " (for example suspended sediment, organism in water, perhaps bubble) be reflected, receive by high sensitive receiver.The principal element that influences the ADV measuring accuracy comprises the salinity of water temperature, water, different sample frequency and sampling height degree etc., and especially the degree of correlation of test data and signal to noise ratio (S/N ratio) directly influence the accuracy of data.
At hydraulics or fluid mechanics laboratory, often utilize tank to carry out the research of knowledge question of water conservancy, wherein the most basic experiment will measure flow velocity exactly.Present a lot of hydraulics or fluid mechanics laboratory are equipped with advanced acoustic Doppler current meter (ADV), are used to measure the two dimension or the three-dimensional flow field of current.Because producer does not provide and the supporting travel mechanism of acoustic Doppler current meter; Measure in the tank flow velocity with the acoustic Doppler current meter in the laboratory very inconvenient; Often through manual work fixing ADV probe simply; It is cumbersome that fixing on the one hand back changes the position, and the simple on the other hand fixing degree of correlation and the signal to noise ratio (S/N ratio) that causes easily testing do not meet accuracy requirement.
Summary of the invention
Measure not convenience of the operation that occurs in the middle of the tank flow velocity in order to solve ADV; Improve the problem of the accuracy of determination data; The present invention provides a kind of novel acoustic Doppler current meter (ADV) mobile device, particularly a kind of ADV mobile device that is applied to hydraulics or the measurement of rate of flow of fluid mechanics laboratory tank.
The technical scheme that the present invention adopts is:
A kind of acoustic Doppler current meter mobile device is characterized in that: comprise stationary installation, elevating lever and base; Said elevating lever comprises fixed part and movable part; Be equipped with chute on said fixed part and the said movable part; Said fixed part be provided with said movable part on the slide rail that is complementary of chute, said movable part is vertically moved with respect to said fixed part; Said fixed part is installed on the said base through bolt, said base be provided with said fixed part on the slide rail that is complementary of chute, said fixed part can laterally move on said base; Said base bottom is equipped with four wheels that can on tank, move; Said stationary installation is circular draw-in groove, is located at the lower end of said elevating lever movable part, through the probe of bolt acoustic Doppler current meter.
Beneficial effect of the present invention is embodied in: easy and simple to handle, regulate flexibly, can accurately the ADV probe be fixed on any position of tank on the one hand, and can effectively reduce test errors on the other hand.
