[0002] As an important energy resource, coal mines face various safety risks during the mining process. Among them, water disasters are one of the main causes of major accidents. Coal mine water disasters are usually caused by groundwater, surface water or accumulated water in the mine, which may cause mine flooding, equipment damage and even casualties. Therefore, effective water disaster prevention and control is crucial for ensuring the safe production of coal mines.

[0003] At present, most of the water level early warning devices for coal mine water control on the market are not sensitive enough to the change of water level, resulting in the inability to capture the tiny change of water level in time, thus unable to achieve real-time monitoring. At the same time, due to the lack of an effective signal processing mechanism, the existing devices are prone to false alarms under the influence of vibration or other non-water level change factors. This not only increases the psychological pressure of miners, but also may cause unnecessary economic losses. Moreover, the existing devices often cannot flexibly set the water level warning line according to the specific safety requirements of coal mines, restricting the practicability and flexibility of the early warning system. Therefore, a water level early warning device for coal mine water control is proposed to solve the above problems. Content of the Utility Model

[0023] A water level early warning device for preventing and controlling water in coal mines, comprising a main body 1, a slider 4, a groove 7, an alarm module 11 and a buoyancy disk 13. A fixed block 15 is fixedly connected to one side of the main body 1, a signal processing module 10 is fixedly connected to the top end of the main body 1, an alarm module 11 is fixedly connected to the upper side of the signal processing module 10. A slider 4 is slidably connected to the inside of the main body 1. A scale 16 is provided on one side of the slider 4, an arrow 6 is provided at one end of the slider 4 close to the scale 16. A groove 7 is provided at the middle position of the slider 4, a pressure sensing module 5 is provided on the upper side of the groove 7, a spring 8 is fixedly connected to the bottom end of the pressure sensing module 5, the other end of the pressure sensing module 5 is fixedly connected to the signal processing module 10. A contact block 9 is fixedly connected to the bottom end of the spring 8. A connecting line 12 is fixedly connected to the bottom end of the slider 4, and one end of the connecting line 12 away from the slider 4 is fixedly connected to a buoyancy disk 13, and a buoyancy block 14 is fixedly connected to the upper side of the buoyancy disk 13.

[0024] Fixing members 2 are fixedly connected to the four corners of the fixed block 15, and fixing holes 3 are provided on the fixing members 2. The fixed block 15 can be firmly fixed by fixing the fixing members 2; the connecting line 12 is a telescopic spiral shape, and the number of the connecting lines 12 is two, which can fix the buoyancy disk 13 on the slider 4; the number of the fixed blocks 15 is two, and the device can be placed on the wall at the position to be monitored; the number of the fixing members 2 is four, and the number of the fixing holes 3 is four, and the water level early warning device can be firmly fixed by using iron nails.

[0025] Workflow: All the power supplies required in this utility model are provided by an external power supply. When the coal mine water control water level warning device needs to be used, first place the fixing block 15 on one side of the main body 1 at the designated monitoring position in the coal mine, and firmly fix the main body 1 on the mine wall through nails, fixing parts 2 and fixing holes 3. According to the specific safety requirements of the coal mine, by sliding the slider 4 up and down, make the arrow 6 point to the required scale 16, and set it as the water level warning line. Check each component of the device to ensure that the connecting wire 12 connects the slider 4 and the buoyancy disk 13, and then place the buoyancy disk 13 and the buoyancy block 14 in the water level monitoring area to facilitate sensing the water level change. The buoyancy disk 13 and the buoyancy block 14 move up and down with the rise and fall of the water level. The connecting wire 12 is a retractable spiral structure, allowing the buoyancy disk 13 to move freely with the water level change. As the water level continuously rises, the buoyancy block 14 will gradually approach the contact block 9 in the groove 7 until it touches the contact block 9. The contact block 9 deforms the spring 8. At this time, the pressure sensing module 5 will sense the pressure change and transmit the signal to the signal processing module 10. The signal processing module 10 conducts intelligent analysis on the collected signal to judge whether it is a real water level change. If it is a stable signal, it is a real water level change, otherwise it is judged as other situations. When the water level reaches or exceeds the preset warning line, the signal processing module 10 activates the alarm module 11, and the alarm module 11 emits a warning signal to remind miners and management personnel to take necessary countermeasures. After receiving the warning signal, the miner or management personnel immediately conduct a manual confirmation of the warning situation. After confirming the abnormal water level, take drainage, evacuate personnel or other safety measures. After the safety measures are completed, reset the warning device, reset the warning water level, and the system returns to the initial monitoring state to continue performing the real-time monitoring task. It is necessary to regularly check and maintain the warning device to ensure its normal operation, calibrate the arrow 6 and the scale 16 according to the actual situation, and adjust the warning line to adapt to the changes in the coal mine environment, ensuring the efficient operation and accurate warning of the coal mine water control water level warning device, and helping to improve the safety management level of the coal mine.
