Description

Technical Field

[0001] The utility model relates to the technical field of groundwater monitoring, in particular to a groundwater level monitoring mechanism used in coal mine development. Background Art

[0002] In the process of coal mining, the application of groundwater level monitoring device is particularly critical. This device can monitor the water level changes under the mine in real time and accurately, providing strong guarantee for the safe production and resource utilization of coal mines. Coal mining is often accompanied by complex changes in hydrogeological conditions. Changes in groundwater levels directly affect the safety and stability of mines.

[0003] In traditional mine water level detection devices, a water level detection device is mostly used to detect the water level in the mine. The detected data is prone to errors. Secondly, the heights in the mines are different. The integrated detection device is inconvenient to install and cannot be used in different mines. Based on these problems, Chinese Patent Publication No. CN209230720U discloses a device for real-time detection of groundwater levels in mines. According to the height in the mine, multiple groups of outer cylinders are connected together by inserting the control seat and the sleeve on the outer cylinder in turn. It can be adapted to mines of different heights and can detect different water levels in the mine. By opening a chute and connecting the float plate and the floating outer ring in the chute, the float plate and the floating outer ring can float upward, and the camera is used to view the number of scale lines corresponding to the top floating outer ring. The height of the water level is calculated by calculating the number of outer cylinders at the bottom and superimposing their total height with the position of the float plate.

[0004] The device mainly uses the floating height of the floating plate and the total height of the outer tube to calculate the water level. Due to the special location of the coal mining area, the groundwater may be mixed with a large amount of mud and fine gravel. These mud and gravel flow into the outer tube with the water flow and adhere to the inner wall of the outer tube and the bottom surface of the floating plate, which will not only cause the structure of the water inlet of the outer tube to be blocked, but also cause the weight of the floating plate to increase, affecting the authenticity of the floating height data of the floating plate.
