Abstract

The invention relates to the field of hydraulic construction safety monitoring and discloses a scouring depth monitoring device and method based on acoustic testing. The device comprises an automatic sedimentation device, a sound wave receiving and transmitting module and a signal processing module, wherein the automatic sedimentation device comprises a sedimentation sleeve, a plugging baffle, a first connecting piece and a sedimentation plate, and the plugging baffle, the first connecting piece and the sedimentation plate are sequentially connected from top to bottom; the blocking baffle, the first connecting piece and the settlement plate are located in the settlement sleeve after being connected and can slide in the axial direction of the settlement sleeve, and a first sealing piece is installed between the blocking baffle and an inner wall of the settlement sleeve; the sound wave receiving and transmitting module is located at an upper end of the settlement sleeve and used for transmitting sound wave signals to the blocking baffle and receiving echo signals reflected by the blocking baffle; the signal processing module is electrically connected with the sound wave receiving and transmitting module and used for processing the sound wave signals and the echo signals, and the settlement amount of the settlement plate is determined according to the wavelengths and the wave speeds of the sound wave signals and the echo signals.

Description

Technical field [0001] The present invention belongs to scour depth monitoring of hydraulic structures, and in particular relates to an apparatus and method for monitoring scour depth acoustic-based testing. Background technique [0002] Many scholars put forward a number of different offshore structures based on monitoring erosion monitoring the principle of technology. Including: monitoring technology buoyancy-driven erosion, gravity-driven erosion monitoring techniques based on conductivity measurement, based on sonar, radar-based monitoring techniques and the like erosion. Wherein buoyancy-driven and gravity-driven erosion monitoring techniques disposable monitoring methods have significant limitations, can not be long, regular monitoring. Monitoring techniques based on conductivity measurements erosion be affixed conductive bars installed outside of a building, easily damaged, the loss of monitoring capability. Erosion monitoring techniques based on sonar and radar; signal a...
