Description

Technical Field

[0002] Tailings ponds are an important part of mine facilities. Whether the tailings pond can operate safely and stably plays an important role in mineral processing and production. Tailings ponds are generally built with tailings sand, and a large amount of tailings and water are piled up in the dam body, forming an artificial "tailings lake". The capacity of the tailings pond gradually increases as the dam body continues to rise. If the dam body collapses, tailings sand, mud, and water will gush out in the form of debris flow, which will pose a serious threat to the lives and property of downstream residents;

If the sludge is not treated, it will affect the accuracy of the piezometer in measuring pressure, resulting in inaccurate water level information. For this reason, we propose a tailings pond water level monitoring device based on piezometer. Utility Model Content

The single-chip microcomputer 8 processes this information and obtains the water level information through the pressure difference between the first osmometer 3 and the second osmometer 4. When too much sludge accumulates in the water inlet pipe 1, the single-chip microcomputer 8 can be regulated. The external oil pump is controlled, and the telescopic rod 28 is operated.
