Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine water hazard prevention and control, specifically a coal mine roadway wall water inrush early warning device. Background Technology
[0002] Coal mine roadway wall water inrush early warning devices are crucial equipment in coal mine safety production. Their design and application are of great significance for preventing water-related accidents and ensuring the safety of personnel and equipment. The water level detection device is the core component of the early warning system, used to monitor the water level on the roadway wall in real time. Common water level detection devices include float-type water level gauges and water level sensors.
[0003] Water level sensors output electrical signals by sensing changes in water level, thereby enabling real-time monitoring of water level. A common method for using water level sensors is to lower the sensor into the groundwater using a rope roller. When the groundwater level changes, the sensor detects the change in water level by sensing the pressure change, thus providing an early warning of water inrush on the tunnel walls. However, existing water level sensors are prone to mutual compression between the ropes during rope deployment and retraction, which can affect the normal deployment and retraction of the ropes and cause damage due to friction between the ropes.

[0012] 1. This utility model uses a motor to drive the rotating shaft to rotate, and the embedded blocks on both sides of the connecting platform drive the rope roller to rotate, thereby realizing the release and retraction of the probe rope. When the rope roller rotates, it is driven to move left and right through the threaded groove and the threaded platform.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a coal mine roadway wall water inrush early warning device, including a mounting plate 1 and a rope roller 5. A mounting frame 2 is fixedly welded to the outer side of the mounting plate 1. A motor 3 is mounted on the outer flange of the mounting frame 2. The output end of the motor 3 passes through the mounting frame 2 and is connected to a rotating shaft 4 via a coupling. Baffles 6 are fixedly welded to both sides of the rope roller 5 to prevent the rope of the water level probe from detaching from the rope roller 5. A sliding groove 7 is opened inside one side of the rope roller 5. The other end of the rotating shaft 4 passes through the sliding groove 7 and is fixedly welded to a connecting platform 8. Embedded blocks 10 are fixedly welded to both sides of the connecting platform 8. An embedded groove 9 communicating with the sliding groove 7 is opened inside the rope roller 5. The probe cable is slidably installed inside the embedded groove 9. The motor 3 drives the rotating shaft 4 to rotate, which drives the rope roller 5 to rotate through the embedded blocks 10 on both sides of the connecting platform 8, thereby realizing the winding and unwinding of the probe cable. The other side of the rope roller 5 has a threaded groove 13 inside, and a threaded platform 12 is threaded inside the threaded groove 13. A fixing rod 11 is fixedly welded to one side of the threaded platform 12. The fixing rod 11 is fixedly welded to the mounting plate 1. When the rope roller 5 rotates, the threaded groove 13 and the threaded platform 12 cooperate to drive the rope roller 5 to move left and right, thereby preventing the cables from pressing against each other. In addition, by changing the diameter of the rope roller 5, it is ensured that probe cables of different lengths are kept in a single layer on the outside of the rope roller 5.
[0021] A connecting piece 28 is fixedly welded between the lower parts of the two mounting plates 1. A connecting plate 14 is fixedly welded inside the connecting piece 28. A positioning box 15 is fixedly welded between the two connecting plates 14. The positioning box 15 is directly opposite the lower part of the rope roller 5. The probe rope moves up and down along the middle of the positioning box 15 to prevent the rope from shifting left and right and causing pressure between the ropes. Two sets of first rolling rods 16 are rotatably installed on the front and rear sides of the positioning box 15. Four sets of mounting pieces 17 are fixedly welded to the left and right sides of the positioning box 15. Second rolling rods 18 are rotatably connected between the mounting pieces 17 on the same side to prevent the rope from rubbing against the inner wall of the positioning box 15 when it moves up and down, which would cause damage to the rope. A moving ring 22 is slidably installed on the outside of the rotating shaft 4. A toothed ring 23 is fixedly welded to the side of the moving ring 22 facing the mounting plate 1. A toothed groove 24 that matches the toothed ring 23 is opened on the outside of the mounting plate 1. Two sets of connecting rings are fixedly welded to the other side of the moving ring 22. 26. A fixing screw 27 is installed inside the connecting ring 26. Two sets of fixing holes 25 are opened inside the rotating shaft 4 to cooperate with the fixing screw 27. By pushing the moving ring 22 along the rotating shaft 4, the toothed ring 23 is inserted into the toothed groove 24. The fixing screw 27 connects the moving ring 22 and the fixing hole 25. The mounting plate 1 prevents the moving ring 22 from rotating and is fixed to the rotating shaft 4 by the fixing screw 27, thereby locking the rotation of the rotating shaft 4 and preventing the position of the water level probe from changing due to the failure of the motor 3. The mounting plate 1 has a structure that is narrow at the top and wide at the bottom. Two sets of contact plates 19 are fixedly welded between the lower parts of the two mounting plates 1 to increase the contact area between the equipment and the ground and ensure the stability of the equipment placement. A curved handle 20 is fixedly welded to one side of the upper part of the mounting plate 1 to facilitate lifting the moving equipment. A cotton cover 21 is rotatably installed on the outer side of the upper part of the handle 20 to protect the hands.
[0022] Working principle: When in use, the mounting plate 1 is placed on one side above the ground roadway. The rope inside the rope roller 5 drives the sensor down to the ground, thereby sensing the water level and water pressure of the groundwater outside the coal mine roadway, thus providing an early warning of water inrush. The motor 3 drives the rotating shaft 4 to rotate, and the embedded blocks 10 on both sides of the connecting platform 8 drive the rope roller 5 to rotate, thereby realizing the release and retraction of the probe rope. When the rope roller 5 rotates, the threaded groove 13 cooperates with the threaded platform 12 to drive the rope roller 5 to move left and right. The rope passes through the middle of the positioning box 15, thereby preventing the ropes from pressing against each other. By pushing the moving ring 22 along the rotating shaft 4, the toothed ring 23 is inserted into the toothed groove 24. The moving ring 22 and the fixing hole 25 are connected by the fixing screw 27. The mounting plate 1 prevents the moving ring 22 from rotating and fixes it to the rotating shaft 4 by the fixing screw 27, thereby locking the rotation of the rotating shaft 4 and preventing the position of the water level probe from changing due to the failure of the motor 3.
