Description

Technical Field

[0001] The utility model relates to the field of manhole covers, in particular to an intelligent manhole cover for dynamic monitoring and protection of groundwater. Background Art

[0002] Smart manhole covers can monitor the status of manhole covers in real time, such as whether they have been moved or damaged, to ensure the safety of underground facilities. In terms of groundwater dynamic monitoring, it can accurately measure important parameters such as groundwater level, water temperature, and water quality. Through built-in pressure sensors, temperature sensors, and water quality detection sensors, the collected data is transmitted to the monitoring system in real time.

[0003] For example, if the groundwater level suddenly rises or falls, the smart manhole cover can quickly detect it and sound an alarm, which is of great significance for preventing geological disasters such as ground collapse caused by abnormal changes in groundwater levels. At the same time, the smart manhole cover can also monitor the pollution of groundwater. Once abnormal water quality is detected, it can promptly notify relevant departments to take measures to prevent further spread of pollution. It greatly improves the efficiency and accuracy of dynamic groundwater monitoring and provides strong support for water resources management and environmental protection.
