Monitoring device and method for monitoring and early warning of hydraulic structure

Abstract

The invention discloses a monitoring device and method for monitoring and early warning of a hydraulic structure. The device comprises a body of the hydraulic structure, a water level monitoring partlocated at one side of the body, a temperature and humidity monitoring part which is located in the body, is 60 to 80cm away from the bottom, and is transversely parallel to the surface of the body, and a seepage pressure monitoring part which is located 30 to 50cm above the temperature and humidity monitoring part, transversely parallel to the surface of the body, and arranged in the body. Each monitoring part is connected with a signal acquisition box, and an audible and visual alarm is further arranged above the body. According to the invention, the hydraulic structure can be monitored for24 hours, various indexes such as the water level, the internal temperature and humidity, the osmotic pressure, the displacement and the stress strain of the hydraulic structure are monitored in realtime, monitored data are uploaded, it is ensured that the hydraulic structure is in a safe state for a long time, and certain economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of monitoring hydraulic structures, in particular to a monitoring device and a monitoring method for monitoring and early warning of hydraulic structures. Background technique [0002] Hydraulic structures include various dams, sluices and dikes, etc. Since the working conditions of hydraulic structures are very complicated, once an abnormal state is found during long-term operation, it must be found and dealt with in time, otherwise it will lead to serious consequences. Safety monitoring is the most important work in hydraulic engineering management. Its purpose is to analyze and evaluate the safety degree of hydraulic structures, so as to take timely measures to ensure the safe operation of hydraulic structures. At present, the safety monitoring system of hydraulic structures has realized semi-automation or automation, and observes and measures the operating status and changes of the buildings through inst...

Problems solved by technology

[0003] Commonly used monitoring items mainly include deformation monitoring, seepage monitoring, stress and strain monitoring, leakage monitoring, seismic monitoring, hidden danger monitoring, temperature monitoring, etc. Patent CN205038019U discloses a dam anti-leakage monitoring device, including a dam body and a monitoring system. An anti-seepage slope is arranged on the dam body; the key points of the structure are: an anti-corrosion layer is arranged on the surface of the anti-seepage slope, a concrete fixed layer is arranged on the lower part of the anti-corrosion layer, and a waterproof coiled material layer is arranged on the lower part of the concrete fixed layer , the lower end of the dam body is provided with an anti-seepage body; the monitoring system is connected with a detector through a signal line, and the detector is connected with a probe group, and the probe group is completely inserted into the anti-seepage slope on the dam body, It has the advantages of good anti-interference, stable performance, and accurate detection results, but the monitoring range and adaptability are not high, and the monitoring results cannot be verified from other angles, which is not conducive to identifying the cause of hidden dangers
