Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, specifically to an intelligent manhole cover with liquid level monitoring. Background Technology

[0002] Manhole covers, as an important component of urban pipe networks, play a crucial role in the construction of modern cities. They are ubiquitous in towns and cities, but if damaged, stolen, overturned, or displaced, they can easily pose significant safety hazards if not addressed promptly, endangering the lives and property of the public. Furthermore, urban pipe network maintenance requires real-time monitoring of water levels. An abnormally high water level beneath a manhole cover, if not detected and addressed promptly, can easily cause backflow of water into the pipe network, severely impacting the surrounding environment.

[0003] Ultrasonic level sensors are generally used to measure the liquid level under the manhole cover. However, when there are impurities floating on the water surface under the manhole cover, it will cause inaccurate liquid level measurement, resulting in smaller liquid measurement data. Ultimately, this leads to inaccurate liquid level measurement data and reduced measurement efficiency. To address this, we propose an intelligent manhole cover with liquid level monitoring.
