Abstract

The invention discloses an integrated measuring device and method for the flow velocity and the depth of a flume test. The integrated measuring device for the flow velocity and the depth of the flumetest comprises a measuring device body, and the measuring device body comprises a measuring instrument and a monitoring probe; the integrated measuring device further comprises switching assemblies for mutual switching of velocity measuring and depth measuring and further comprises an adjusting device for adjusting the position of the measuring device body, and the adjusting device comprises a left-right position adjusting assembly, a front-rear position adjusting assembly and a height adjusting assembly; and the switching assemblies are connected with the height adjusting assembly. Accordingto the integrated measuring device, velocity measuring and depth measuring can be converted, and a depth measuring device and a velocity measuring device are integrated; the problems that traditionalequipment is limited in measuring space, inflexible in moving, complex in operation and long in consumed time can be effectively solved; and compared with a traditional flume scouring test, the integrated measuring device for the flow velocity and the depth of the flume test is simple in structure, small in occupied space, convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of scouring tests, in particular to an integrated measuring device and method for flow velocity and depth of a water tank test. Background technique [0002] Doppler speed measuring and depth sounding equipment are widely used in underwater operation systems. Doppler log is an important acoustic device for calculating carrier velocity vector according to Doppler effect. Doppler depth sounder is the use of echo Signal time difference to calculate depth. At present, most hydrodynamic tests use the sounding equipment and speed measuring equipment as two independent systems, which is not only inconvenient to install, but also takes up a lot of space. [0003] Bridges across rivers are an important part of modern transportation. Excellent bridge engineering design should not only achieve safe, reliable and economical structural design, but also require hydrological and hydraulic design to meet certain standards ...
