[0002] Coal mining is the exploitation of underground coal resources. Regardless of open-pit or underground mining, geological exploration must be carried out first to find out the distribution range of coal-bearing strata, the number of mineable layers, layer thickness, inclination, and reserves. It is inevitable that certain groundwater leakage will occur during the coal mining process. The premise of water conservation in coal mining is that there is both water and coal. The purpose of water conservation under coal mining conditions is to protect the environment and the ecology. Due to the large water flow in the process of water conservation coal mining, water gathers in the excavated tunnels. Timely warnings are needed to avoid water flooding into the working space and ensure the safety of miners.

[0003] However, the existing water-preserving coal mining water level warning devices are mostly fixedly installed with bolts, and verticality adjustment is required to ensure the vertical state of the device within the water level, thereby ensuring the accuracy of the warning water level. Ordinary water level warning devices cannot automatically adjust the vertical state, and are not convenient to place at multiple points. The scope of application is small and the use is not convenient. Based on this, the utility model designs a water-preserving coal mining water level warning device to solve the above problems.
