Problems solved by technology
[0003] Underground water control in coal mines is an important link to ensure safe production in coal mines. It is necessary to detect and diagnose various water hazards that threaten mine production, such as fault water in mines, coal seam roof and floor water, subsidence column water, and surface water, and timely early warning and pre-control when abnormalities are found. , the dangerous early warning function is poor and it is easy to cause coal mine water damage. It is necessary to improve the sealing of the early warning equipment. Therefore, a coal mine underground water prevention early warning device is needed to improve the above problems

The invention relates to the technical field of coal mine underground water prevention and control devices, in particular to a coal mine underground water prevention and control early-warning device.The coal mine underground water prevention and control early-warning device comprises an early-warning device body, early-warning broadcasting equipment and a base, an internal mounting frame is mounted in the early-warning device body through bolts, the early-warning broadcasting equipment is mounted on the upper part of the base surface of the internal mounting frame through bolts, a telemetering terminal is mounted on the side, close to the lower end of the early-warning broadcasting equipment, of the upper part of the base surface of the internal mounting frame through bolts, the early-warning broadcasting equipment and the telemetering terminal are fixedly connected with a terminal processor, and the end, away from the early-warning broadcasting equipment and the telemetering terminal, of the terminal processor is fixedly connected with a data analysis terminal. An internal sealing structure is formed through the early-warning device body, a locker, a locker fixing seat, a wire box and a sealing ring, an internal fixed mounting structure is adopted as an overall precision element, the integrated early-warning device body is adopted externally, corrosion of water vapor and dustto internal elements is avoided, and overall sealing performance is effectively improved.
Description
technical field [0001] The invention relates to the technical field of underground water prevention and control devices in coal mines, in particular to an early warning device for underground water prevention and control in coal mines. Background technique [0002] Coal mine water disasters are second only to gas disasters among the five major coal mine disasters, and are universal and threatening. It is necessary to fully understand the main types of flood disasters and the main causes of disasters, so as to provide effective reference for coal mine water disaster control. [0003] Underground water control in coal mines is an important link to ensure safe production in coal mines. It is necessary to detect and diagnose various water hazards that threaten mine production, such as fault water in mines, coal seam roof and floor water, subsidence column water, and surface water, and timely early warning and pre-control when abnormalities are found. , the dangerous early warnin...
