[0025] In this embodiment, the plug-in slot 13 is used to electrically connect the sound and light alarm 7 and the battery 8, and the plug-in slot 13 and the conductive block 12 are adapted in shape;

[0026] The conductive block 12 is inserted into the plug slot 13 to connect the sound and light alarm 7 and the battery 8, and provide power for the sound and light alarm 7 to generate a sound and light alarm, thereby reminding the staff and evacuating in time to protect the life safety of the staff.

[0027] In this embodiment, a stretching column 14 is slidably penetrated on one side of the top of the connecting sleeve 6 corresponding to the battery 8, and a limit plate 15 is fixedly connected to the outer wall of the stretching column 14. A tension spring 16 is fixedly connected to both sides of the stretching column 14 at the bottom of the limit plate 15 corresponding to the two sides of the stretching column 14, and the two tension springs 16 are fixedly connected to the connecting sleeve 6;

[0028] The tension column 14 and the limit plate 15 can be reset by the tension spring 16, and the symmetrical arrangement ensures that the force conditions on both sides of the limit plate 15 are the same to avoid jamming.

[0029] In this embodiment, handles 17 are fixedly connected to the top of the connecting sleeve 6 on both sides corresponding to the sound and light alarm 7. When disassembling or adjusting the position, the handles 17 can be held by hand to provide support force for the connecting sleeve 6.

[0030] In this embodiment, a triangular block 18 is fixedly connected to the bottom end of the stretching column 14, and both ends of the triangular block 18 are slidably connected to the limiting column 19 and penetrate the connecting sleeve 6;

[0031] Due to the characteristics of the triangular block 18, the limiting column 19 can be moved inward or outward, thereby releasing the limiting of the connecting sleeve 6.

[0032] In this embodiment, a plurality of evenly arranged limiting grooves 20 matching the shape of the limiting columns 19 are provided on both sides of the inner wall of the fixed cylinder 1;

[0033] When the limiting column 19 is inserted into the limiting groove 20, the connecting sleeve 6 is limited, thereby completing the position adjustment.

[0034] In this embodiment, a fixed cone 2 is fixedly connected to the bottom end of the fixed cylinder 1, a mounting plate 3 is fixedly connected to the top of the outer wall of the fixed cylinder 1, and fixed plugs 4 are fixedly penetrated at both ends of the top of the mounting plate 3 corresponding to the fixed cylinder 1, and the fixed plugs 4 are used to be inserted into the soil in the coal mine.

[0035] It should be noted that the utility model is a coal mine geological water prevention and control early warning device. When in use, the fixed cone 2 and the fixed cylinder 1 are first inserted into the coal mine, and the fixed cylinder 1 and the fixed cone 2 are limited and fixed by the fixed plug column 4. The water in the coal mine will first pass through the filter plate 5 to filter out the mud in the water to prevent the mud from being stuck between the fixed cylinder 1 and the connecting sleeve 6 to affect the adjustment;

[0036] When the water in the coal mine reaches a certain height, the floating plate 11 will move upward, so that the conductive block 12 is inserted into the plug slot 13 and the sound and light alarm 7 and the battery 8 are connected. At this time, the sound and light alarm 7 will emit a sound and light alarm to remind the staff, thereby preventing water damage in the coal mine and ensuring the life safety of the staff;

[0037] Then, by holding the handle 17 and stretching the stretching column 14 upwards, the triangular block 18 is moved. At this time, the limit column 19 will move inward and leave the limit groove 20. At this time, the connecting sleeve 6 can be removed to facilitate the cleaning of the connecting sleeve 6, and the position of the connecting sleeve 6 can also be changed to make the limit column 19 align with the limit grooves 20 at different positions. Then, the stretching column 14 is released and the stretching column 14 is reset under the reset action of the tension spring 16, so that the limit column 19 moves outward and is inserted into the limit groove 20 to complete the position adjustment. Therefore, it can be applied to different coal mines, thereby improving the practicability of the device.
