[0002] With the continuous changes in the mining depth and mining conditions of coal mines, especially after mergers and reorganizations, due to unclear geological data, coal mines are increasingly threatened by goafs, ancient goafs, and Ordovician limestone water, which brings great difficulties to the prevention and control of mine water hazards. Therefore, coal mine water hazards have become a major key issue affecting coal mine safety production. Therefore, doing a good job in water hazard prevention is the key work in coal mines. Generally, an early warning device will be placed on the ground of the coal mine to prevent water;

[0003] In the prior art, due to the wide range of the ground, water will flow everywhere, resulting in a slow rise in the water level, thereby delaying the warning time, which is easy to lead to accidents caused by untimely treatment. In response to the above problem, the application number is: 202220663677.3, which discloses a coal mine shaft water prevention and control device, which includes a water level detector, the outer side of the water level detector is connected to a water collecting tank, the top of the water collecting tank is fixedly connected to a water guide box, the top of the water guide box is connected to a water guide frame, a second water inlet is opened on the inner side of one end of the water guide box, and the bottom of the water guide box is provided with a second water inlet. A second water inlet is opened on the side, one end of the water guide frame and the water guide box are fixedly connected to a supporting mechanism, and a filtering mechanism is arranged on the top of the water guide box, so that one side of the water guide frame and the water guide box is embedded in the inner wall of the wellbore, and water seeping from the inner wall is collected through the first water inlet and the second water inlet, so that the water quickly flows to the inner side of the water collecting box, ensuring that the water seeping from the inner wall does not flow on the ground, so that the phenomenon of water flowing everywhere affecting the water level rise does not occur, and the accuracy of the water level rise is ensured, thereby ensuring timely alarm, so that the staff can deal with the inner wall seepage phenomenon in time

[0034] In this embodiment, two grooves 1 are provided on the top of the multiple fixed frames 3, and the multiple grooves 1 correspond to the multiple fixed rods 6 respectively. The multiple fixed rods 6 are respectively engaged with the multiple grooves 1 to limit the corresponding fixed frames 3 and prevent the fixed frames 3 from detaching from the corresponding installation grooves.

[0035] In this embodiment, the plurality of fixing rods 6 are all slidably connected to the water guide box 1 , and the plurality of fixing rods 6 slide in the plurality of slots respectively, so as to limit the positions of the plurality of fixing rods 6 .

[0036] In this embodiment, the detection mechanism includes a collecting box 8, a control module 9, a water level detector 10 and a water pipe 11.

[0040] Working principle: When in use, first embed the water guide box 1 into the inner wall of the wellbore, then drive the hydraulic cylinder 13 and make the fixed steel nail 14 abut against the inner wall of the wellbore, so as to achieve the effect of mechanical energy limiting and fixing of the water guide box 1;

[0041] When water seepage occurs on the inner wall of the wellbore, the water will flow into the water guide box 1 through multiple filter screens 4, and the soil and gravel on the inner wall of the wellbore will be mechanically filtered by the filter screens 4. Then, the water in the water guide box 1 will be transported to the collection box 8 through the water pipe 11, and the water level in the collection box 8 will be detected by the water level detector 10. When the water in the collection box 8 rises to the position of the water level detector 10, the water level detector 10 transmits a signal to the control module 9, and then the control module 9 controls the alarm to sound an alarm, thereby reminding the staff to deal with the water seepage problem on the inner wall of the wellbore in time.

[0042] When multiple filter screens 4 need to be replaced, first take the water guide box 1 out of the inner wall of the wellbore, then pull the round rod 2 7 through the baffle 16 and make the round rod 2 7 slide a certain distance on the water guide box 1 and make the spring stretched, so that the multiple slots on the round rod 2 7 release the limit of the multiple fixing rods 6, then, rotate the round rod 1 5 through the rotating plate 15, so that the round rod 1 5 rotates a certain angle on the water guide box 1, and at the same time, the round rod 1 5 drives the multiple fixing rods 6 to rotate synchronously by a certain angle, and makes the multiple fixing rods 6 respectively disengage from the multiple slots and the multiple grooves 1, so that the multiple fixing rods 6 release the limit of the multiple fixing frames 3, finally, take out the multiple fixing frames 3 from the multiple installation grooves on the water guide box 1, thereby achieving the purpose of disassembling the multiple filter screens 4;

[0043] On the contrary, the effect of fixing and installing a plurality of fixing frames 3 is achieved.

[0044] The technical progress achieved by the present invention compared with the prior art is that the multiple filter components can be quickly installed and disassembled without external tools through the cooperation of various components, and the structure is simple and easy to operate, which improves convenience and practicality.
