[0002] Coal mine water hazard is one of the five major disasters along with gas, coal dust, roof, fire, etc., and its severity ranks second only to gas. With the continuous changes in mining depth and mining conditions, especially after mergers and reorganizations, due to unclear geological data, coal mines are increasingly threatened by goafs, ancient goafs, and Ordovician ash water, which brings great difficulties to mine water hazard prevention and control work. Therefore, coal mine water hazard has become a major key issue affecting coal mine safety production. Therefore, doing a good job in water hazard prevention and control is the key work in coal mines.

[0003] Traditional warning systems for water seepage in coal mines are relatively weak. Alarms are only sounded when the amount of water seepage is large, resulting in untimely rescue and maintenance work at the water seepage site, causing losses. In addition, since the water level warning heights are different in different construction environments underground, traditional alarm devices cannot adjust the warning water level height, and cannot meet the monitoring needs of various construction environments underground, affecting the use effect.

[0004] Therefore, there is a need for an underground water prevention and control early warning device for coal mines to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 6 , a coal mine underground water prevention and control early warning device, including a base 1, both sides of the base 1 are provided with fixing mechanisms for convenient installation and fixing of the base 1, the inside of the base 1 is penetrated by a plug-in tube 8, and is threadedly connected with the plug-in tube 8, a turntable 9 is provided on the top outer side of the plug-in tube 8, and a water collecting tube 10 is rotatably connected to the inside of the plug-in tube 8, and the sides of the plug-in tube 8 and the water collecting tube 10 are respectively provided with multiple groups of first through grooves 12 and multiple groups of second through grooves 13 near the bottom, and the multiple groups of first through grooves 12 are respectively matched with the multiple groups of second through grooves 13, and the inner side of the water collecting tube 10 is provided with an early warning mechanism for convenient water level monitoring;

[0026] The early warning mechanism includes a floating plate 14 arranged at the bottom of the inner side of the water collecting cylinder 10, and a resistance rod 15 is arranged on the top of the floating plate 14. A piston 18 is slidably connected to the inner side of the water collecting cylinder 10, and an adjustment mechanism for facilitating height adjustment is connected to the top of the piston 18. A pressure sensor 19 adapted to the resistance rod 15 is installed at the bottom of the piston 18. Alarms 20 and alarm lights 21 are installed on both sides of the base 1, and are used in conjunction with the pressure sensor 19.

[0027] Specifically, the base 1 and the fixing mechanism are provided to facilitate the installation and fixation of the device, and a stable working platform can be provided for water level monitoring. The turntable 9 is provided to drive the plug-in tube 8 to rotate. The plug-in tube 8 can be driven to move downward and plugged into the ground through the threaded connection with the base 1. The multiple groups of first through grooves 12 and multiple groups of second through grooves 13 are provided to facilitate water penetration into the interior of the water collecting tube 10. As the water level inside the water collecting tube 10 rises, the floating plate 14 and the resistance rod 15 can be driven to float upward. When one end of the resistance rod 15 conflicts with the DLK213 pressure sensor 19 of a set height, the DLK213 pressure sensor 19 can transmit a signal to the control system, and the control system can control the opening of the alarm 20 and the alarm light 21. Furthermore, through the above structure, the water seepage phenomenon can be monitored and alarmed, which facilitates the rescue and maintenance work at the water seepage site.

[0028] Among them, two groups of toggle rods 11 are installed on the outer side of the top of the water collecting barrel 10. When the device is in working state, multiple groups of second through grooves 13 are respectively aligned with multiple groups of first through grooves 12. Through the set toggle rods 11, the water collecting barrel 10 can be easily driven to rotate, so that when the device is in non-working state, the multiple groups of second through grooves 13 can be staggered with the multiple groups of first through grooves 12 to avoid the second through grooves 13 being blocked by foreign objects and affecting the water collecting effect of the water collecting barrel 10.

[0029] Among them, the adjustment mechanism includes a screw lift 16 installed on the top of the water collecting cylinder 10, and the screw lift 16 is threadedly connected with a screw 17. One end of the screw 17 extends to the interior of the water collecting cylinder 10 and is connected to the top of the piston 18.

Furthermore, through the setting, it can meet the monitoring needs of various construction environments underground and improve the use effect of the device.

[0030] Among them, the fixing mechanism includes two groups of support rods 2 hingedly connected to both sides of the base body 1, and the other ends of the corresponding two groups of support rods 2 are connected through the bottom plate 3.

A crank 5 is provided on the outer side of the top of the rotating seat 4, and two groups of protrusions are provided at the bottom of the plug-in rod 6 to limit its rotation. By unfolding the corresponding two groups of support rods 2 and then inserting the two groups of plug-in rods 6 into the ground, the fixing of multiple groups of support rods 2 and the base body 1 can be completed. When disassembly is required, the crank 5 can be turned, and the crank 5 can drive the rotating seat 4 to rotate. The rotating seat 4 can be conveniently driven to pull up the plug-in rod 6 plugged into the ground under the action of the threaded connection with the plug-in rod 6 and the joint action of the two groups of protrusions. Therefore, the disassembly convenience of the device is greatly improved through the setting.

[0031] Among them, two groups of fixing seats 7 for accommodating the support rod 2 are provided on both sides of the base 1 near the bottom. The fixed seats 7 can facilitate the storage of the support rod 2. A handle 22 is installed on the top of the base 1. The handle 22 is provided in two groups. The two groups of handles 22 can facilitate the carrying of the device.

[0032] Working principle: First, unfold the corresponding two groups of support rods 2, then insert the two groups of plug-in rods 6 into the ground to complete the fixation of multiple groups of support rods 2 and the base 1, and then start the screw lift 16, the screw lift 16 can drive the screw 17 to move up and down, the screw 17 can drive the piston 18 to move up and down, and the piston 18 can drive the DLK213 pressure sensor 19 installed at the bottom to move up and down, so that the height of the warning water level can be adjusted as needed, and then, by rotating the turntable 9, the turntable 9 can drive the plug-in tube 8 to rotate, and the plug-in tube 8 can drive the plug-in tube 8 through the threaded connection with the base 1. The cylinder 8 moves downward and is plugged into the ground.
