Riverbed scouring depth real-time monitoring system and monitoring method

Abstract

The invention discloses a riverbed scouring depth real-time monitoring system, which comprises a riverbed, wherein a riverway is defined by the riverbed and two banks of the riverbed, a fixing structure is arranged above the riverway, the fixing structure is downwards connected with a plurality of red connecting wires, and the connecting wires are arranged in the vertical direction; the connectingwires are carbon fiber wires, the lower ends of the connecting wires are fixedly connected with floating balls, and the density of the floating balls is smaller than or equal to 0.2 g / cm<3>; each floating ball is respectively pre-buried in the riverbed at a preset depth; the top part of each connecting wire is connected with an indication board, and the indication boards are used for indicating the pre-buried depth of the corresponding floating balls. The riverbed scouring depth real-time monitoring system avoids deviation caused by the fact that a gravity probe rod blocks water flow , and the defects that a sonar system is high in cost, cannot be directly observed and the like are further avoided. By means of a buoyancy principle, the change condition of riverbed scouring can be conveniently and visually seen by a worker while the result is accurate, and meanwhile the worker can observe and check the recorded riverbed scouring condition at any time on the display screen.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to the monitoring technology of riverbed scouring depth. Background technique [0002] The river bed scouring experiment is a common river engineering model experiment. In water conservancy-related research, it is often necessary to carry out river bed scouring experiments. etc.) provide a basis for the development trend of the lower riverbed. [0003] In the riverbed scour experiment, real-time monitoring of the riverbed scour depth is required. In some river sections in reality, real-time monitoring of the riverbed depth is also required. Whether in the laboratory or in real rivers, it is not easy to accurately monitor the depth of the riverbed in real time. [0004] In the existing research, some people have proposed a gravity-type riverbed depth monitoring method. A probe rod is set in a protective pipe or sheath, a bottom plate is set at the bottom of t...

Problems solved by technology

Another shortcoming of sonar technology is that it cannot enable the staff to visually observe the changes in the scour depth of the river bed like the probe rod
