Real-time monitoring system and monitoring method for river bed scour depth

Abstract

The invention discloses a real-time monitoring system for the scour depth of a river bed, which comprises a river bed, the river bed and its two sides are surrounded by a river channel, a fixed structure is arranged above the river channel, and a plurality of red connecting wires are connected downwards to the fixed structure, and each connecting wire is along the vertical direction Setting; the connecting wires are carbon fiber wires, and the lower ends of each connecting wire are fixedly connected with floating balls, and the density of the floating balls is less than or equal to 0.2 g / cubic centimeter; each floating ball is pre-buried in the riverbed at a predetermined depth; An indicator board is connected, and the indicator board is used to indicate the pre-embedded depth of the corresponding floating ball. The invention avoids the deviation caused by the gravity probe rod blocking the water flow, and also avoids the high cost of the sonar system and the inability to observe directly. The invention utilizes the principle of buoyancy to achieve accurate results and allow workers to conveniently and intuitively see the change of river bed scour, and at the same time the staff can also observe and check the recorded river bed scour conditions on the display screen at any time.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to the monitoring technology of river bed scour depth. Background technique [0002] The river bed scour test is a common river engineering model experiment. In water conservancy related research, it is often necessary to carry out the river bed scour test. The river bed scour test is used to predict a certain flow condition (including river shape, hydrological sediment, river bed characteristics, water volume and velocity) etc.) to provide evidence for the development trend of the lower riverbed. [0003] In the river bed scour experiment, real-time monitoring of the river bed scour depth is required. In some river sections in reality, real-time monitoring of river bed depth is also required. Whether it is in the laboratory or in the real river, there is the problem that it is not easy to monitor the depth of the river bed accurately in real time. [0004] ...

AI Technical Summary

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
