[0021] like Figure 1 The utility model is different from the prior patent application mentioned in the background technology in that the utility model uses a float 5 to monitor the water level in the mine, and buries the monitoring device under the ground in the mine, thereby reducing the damage to the monitoring device caused by falling rocks or other transportation tools in the mine. The monitoring device includes a storage box 20, a connecting rope 8 and a float 5. The storage box 20 is buried under the ground in the mine, and a storage slot 11 is provided in the storage box 20. The connecting rope 8 is provided in the storage slot 11, such as Figure 2 As shown, the storage groove 11 is spiral, and the spiral storage groove 11 can accommodate a longer length of the connecting rope 8. A positioning ball 12 is provided at one end of the connecting rope 8 located in the storage groove 11, and the other end of the connecting rope 8 passes through the storage box 20 and extends above the ground in the mine. A floating ball 5 is provided on the end of the connecting rope 8 located above the ground.

[0022] like Figure 1 As shown, the storage box 20 is composed of an upper shell 2 and a lower shell 1. The storage box 20 is a detachable structure. The upper shell 2 and the lower shell 1 are provided with corresponding fixing holes, which are respectively located at the four corners of the upper shell 2 and the lower shell 1. Fixing bolts 3 are installed in the fixing holes. A sleeve 4 is provided on the upper shell 2, and the sleeve 4 extends to the ground in the mine. The purpose of setting the sleeve 4 is to allow the connecting rope 8 to extend from the ground in the mine more smoothly as the float 5 rises. The material of the sleeve 4 is plastic. After the storage box 20 is buried under the ground in the mine, the excess space between the sleeve 4 and the ground is trimmed.

[0023] like Figure 2 and Figure 3As shown, monitoring slots 19 are arranged in sections in the storage slot 11, and pressing blocks 14 are arranged in the monitoring slots 19. Springs 18 are arranged in the monitoring slots 19, and movable blocks 17 are arranged on the springs 18. A control switch 15 is arranged at the place where the movable block 17 and the pressing block 14 face each other, and a wireless transmission module is arranged in the movable block 17. When the control switch 15 contacts the pressing block 14, the wireless transmission module will transmit the signal to the monitoring alarm box 6, and the warning light 7 on the monitoring alarm box 6 will light up. By observing the warning light 7 on the monitoring alarm box 6, the water level position in the mine can be known. An arc block 16 is provided at the bottom of the movable block 17, and the sides of the arc block 16 are in contact with the inner wall of the monitoring groove 19, so as to prevent water from seeping into the monitoring groove 19 when water enters the storage box 20, thereby damaging the control switch 15 of the wireless transmission module. The bottom of the arc block 16 is an arc structure, so when the positioning ball 12 passes under the arc block 16, the arc-shaped contact surface can make it easier for the positioning ball 12 to pass under the arc block 16. When the positioning ball 12 passes, it will squeeze the movable block 17 to one side, so that the control switch 15 on the movable block 17 contacts the pressing block 14. A power supply for the wireless transmission module is provided in the movable block 17, and the power supply is electrically connected to the wireless transmission module.

[0024] like Figure 1 and Figure 5 As shown, a reset hole 21 is also provided on the upper shell 2, and the reset hole 21 passes through the upper shell 2 and is connected with the receiving groove 11. Specifically, the position of the reset hole 21 corresponds to the center position of the spiral receiving groove 12. A reset rope 13 is provided in the reset hole 21, and a sleeve 4 is also provided on the reset hole 21. One end of the reset rope 13 passes through the reset hole 21 and is connected with the sleeve 4 set on the reset hole 21 and the positioning ball 12. The other end of the reset rope 13 passes through the positioning hole 21 and extends to above the ground in the mine. In this way, the positioning ball 12 can be reset by dragging the reset rope 13.

[0025] like Figure 4 As shown, a fixing block 9 is provided on the top of the float 5, and a through hole with the same central axis is provided on the fixing block 9 and the float 5, and a positioning hole is provided on the side of the through hole, and the connecting rope 8 passes through the middle of the through hole and passes out from the through hole on the fixing block 9, and the positioning hole is connected with the through hole, and a positioning bolt 10 is provided in the positioning hole, and the positioning bolt 10 is mainly used to fix the connecting rope 8 in the through hole. The purpose is to make the float 5 stick to the ground after the storage box 20 is installed, and then trim the excess connecting rope 8 above the fixing block 9, and after trimming, fix the connecting rope 8 and the float 5 by the positioning bolt 10.

[0026] like Figure 1As shown, warning lights 7 are provided in sections on the monitoring alarm box 6, and a receiving module is provided in the monitoring alarm box 6. The receiving module is used to receive the signal transmission of the wireless transmission module. The warning lights 7 are electrically connected to the receiving module. Each warning light 7 corresponds to a wireless transmission module in a monitoring slot 19. When the wireless transmission module transmits a signal to the receiving module, the corresponding warning light 7 will continue to light up. The water level in the mine can be observed based on the corresponding warning light 7. A reset switch is provided on the monitoring alarm box 6. When the accumulated water in the mine is cleaned up, the reset switch can be pressed to turn off the continuously lit warning light 7.

[0027] The specific use method of the utility model is briefly described as follows:

[0028] First, dig up the ground in the mine, then put the storage box 20 into the dug pit and place the casing 4, connecting rope 8 and float 5 above the ground. After burying the storage box 20, trim the excess casing 4, and then make the float 5 stick to the ground above the casing 4. Next, fix the connecting rope 8 with the positioning bolt 10. After fixing the connecting rope 8, trim the excess connecting rope 8 above. After trimming, it can be used. Place the monitoring alarm box 6 in the drainage pump room. The staff on duty in the drainage pump room can observe the water level in the mine in real time, so as to pump water in the mine in time. When there is water accumulation in the mine and the water level rises, the float 5 will rise with the water level. While the float 5 rises, it drives the connecting rope 8 further When the connecting rope 8 rises, it drives the positioning ball 12 to move in the storage groove 11. When the positioning ball 12 touches the arc block 16, the movable block 17 moves to one side, and the control switch 15 on the movable block 17 contacts the pressing block 14 in the monitoring groove 19. The pressing block 14 presses the control switch 15. At this time, the wireless transmission module will transmit a signal to the monitoring alarm box 6. The wireless transmission module transmits the signal to the monitoring alarm box 6 located in the pump room. After the monitoring alarm box 6 receives the signal, the warning light 7 at the corresponding position continues to light up, and the water level position in the mine can be judged by the warning light 7. When the water level drops, the warning light 7 is reset by the reset switch on the monitoring alarm box 6, and the positioning ball 12 is reset by pulling the reset rope 13.
