Three-dimensional scanning automatic detection device and method for dam leakage electric field

Abstract

The invention discloses a dam seepage electric field three-dimensional scanning automatic detection device, which is characterized in that a multi-frequency electric field signal transmitter of the device is placed on a dam, an electric field negative electrode is arranged in a water body, which is 200m-1000m away from a suspicious seepage point, at the upstream of the dam, an electric field positive electrode is arranged in a water body at the downstream of the dam, the electric field negative electrode is connected to a negative electrode wiring terminal of the electric field signal transmitter, the electric field positive electrode is connected to a positive electrode wiring terminal of the electric field signal transmitter, and the electric field positive electrode, the multi-frequency electric field signal transmitter, the electric field negative electrode and the suspicious seepage point form a power supply electric field loop; and a field receiving system is used for performing detection on the power supply electric field loop and can determine an electric field gathering area, so that the location of the dam seepage point is tracked. The dam seepage electric field three-dimensional scanning automatic detection device and method can perform automatic tracking and quick searching on the dam seepage point.

Description

technical field [0001] The invention relates to the technical field of geophysical detection, in particular to a three-dimensional scanning automatic detection device and method for leakage electric field of dykes and dams. Background technique [0002] For a long time, many domestic scientific research workers have been researching on dam leakage monitoring technology without interruption, and have made some progress. However, there are still many researches on the accurate positioning and qualitative and quantitative interpretation of dam leakage. insufficient. According to the information currently available, there is no monitoring device that is fully suitable for the detection of hidden dangers in embankments, especially the monitoring devices that can quickly and accurately detect dangerous situations in dikes during the flood season. At the same time, although the principle of detection of hidden dangers in dykes and dams is the same as that in the field of ore prosp...

Problems solved by technology

The advantage of underground magnetic fluid detection technology lies in: the use of natural electromagnetic field as the source of the work field, low cost and high work efficiency; but there are also some shortcomings: the detection signal is weak, the research theory has not formed a system, and the existing instruments are advanced. and reliability are still lacking
