Device and method for monitoring suspension length development in submarine pipeline scouring test in real time

The invention discloses a real-time monitoring device and method for suspension length development in a submarine pipeline scouring test, and relates to the field of submarine pipeline scouring suspension length test measurement, the device comprises a submarine pipeline and a suspension discrimination sensor, the submarine pipeline is arranged on an experiment seabed, and the experiment seabed is arranged at the bottom of an experiment water tank; the plurality of suspended discrimination sensors are arranged at the bottom of the submarine pipeline at equal intervals, the suspended discrimination sensors are connected with a data acquisition unit through electric wires, and the data acquisition unit is connected with a computer. The invention provides the real-time monitoring device for the suspension length development in the submarine pipeline washout test, which can reduce pipeline limitation, can work under a muddy water condition and is easy to realize, and the use method thereof. 本发明公开了一种海底管道冲刷试验中悬空长度发
