Technical Field
[0001] This utility model relates to the field of monitoring water inrush from fractured surrounding rock in water-rich roadways, specifically to a monitoring and alarm device for water inrush from fractured surrounding rock in water-rich roadways. Background Technology
[0002] Coal mine safety under complex hydrogeological conditions is a challenging problem. Coal seams are threatened by various water bodies during mining, leading to frequent water inrush accidents in mine roadways. These accidents can cause significant economic losses and casualties, while also damaging the water resources environment of the mining area. Currently, the assessment of abnormal water inrushes in water-rich environments is mainly based on on-site qualitative evaluation. This includes relying on experiences such as red-hot spots, sweating, cooling air, fogging, water hissing, increased roof water seepage, roof pressure, floor bulging or cracking leading to seepage, turbid water, and foul odors as indicators that a water inrush may develop into a water hazard. Preventive measures also depend solely on geological and hydrological data, lacking a systematic and effective monitoring and early warning system.
[0003] Traditional methods for monitoring water inrush in water-rich tunnels, such as manual inspections and simple water level monitoring, suffer from drawbacks including untimely monitoring, low accuracy, and inability to accurately determine the location and scale of the inrush. With the continuous expansion and increasing complexity of underground engineering projects, these traditional methods are no longer sufficient to meet practical needs. Utility Model Content

[0011] Beneficial effects
[0012] This invention provides a monitoring and alarm device for water inrush and fracture in the surrounding rock of water-rich roadways. Compared with the prior art, it has the following advantages:
[0013] (1) By setting up components such as airbags and buoyancy balls, the water level changes in the tunnel can be monitored in real time. When the surrounding rock fractures and water surges, causing the water level to rise, the buoyancy ball rises and drives the sliding plate to move, triggering the alarm and issuing an alarm signal in a timely manner to remind the staff to take measures, thereby effectively avoiding safety accidents caused by water surge and ensuring the safety of personnel and equipment. Through the design of the transportation mechanism, including components such as transportation pipes, inlets, detachable sealing ports, and collection boxes, it is convenient to collect and transport the surging water. The drive motor drives the rotating shaft to rotate, which in turn drives the spiral conveyor shaft to rotate, which can transport the water sample in the collection box to the designated location through the transportation pipe, facilitating further analysis and testing of the water sample, helping to accurately determine the source and nature of the surging water, and providing a basis for subsequent treatment work.
[0014] (2) The monitoring tank is fixed by a support plate. The mounting plate is fixed with components such as an air pump and an alarm. The overall structure is stable. At the same time, the connection between the components is simple. For example, the detachable sealing port is connected to the mounting frame by fixing bolts, which facilitates the installation, disassembly and maintenance of the device, reduces the cost of use and improves the practicality and reliability of the device. The airbag is connected around the outer wall of the monitoring tank. According to different roadway environments and monitoring needs, the airbag can be inflated or deflated by the air pump to adjust the buoyancy and stability of the device, so that it can adapt to different water levels and water flow conditions, thus expanding the applicability of the device.

[0020] 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.
[0021] Example 1:
[0022] Please see Figure 1-4As shown in the figure, this embodiment proposes a monitoring and alarm device for water inrush monitoring in a water-rich roadway with fractured surrounding rock. The device includes a monitoring tank 1, an airbag 2 connected to the outer wall of the monitoring tank 1, a mounting plate 3 fixed to one side wall of the monitoring tank 1, a support plate 4 fixed to the lower surface of the monitoring tank 1, an air pump 5 fixed to the upper surface of the mounting plate 3, a flow pipe 6 fixed to one side wall of the air pump 5, and the flow pipe 6 connected to the airbag 2. A transport mechanism is provided on the lower surface of the monitoring tank 1, including a transport pipe 16 located on the lower surface of the monitoring tank 1 for receiving and transporting the inrushing water. An inlet 17 is fixed to the lower surface of the transport pipe 16, and a detachable sealing port 18 is movably connected to the lower surface of the inlet 17. The detachable sealing port 18 facilitates the installation of new sealing ports as needed. When the water flows into the collection tank 20, the detachable sealing port 18 is opened to allow the water to flow smoothly into the collection tank 20. The detachable sealing port 18 is movably connected to the side wall of the collection tank 20 by a fixing bolt 19. The outer wall of the collection tank 20 is fixed to a fixing seat 21, and the upper surface of the fixing seat 21 is fixed to a mounting frame 22. The fixing bolt 19 passes through the interior of the mounting frame 22 and is connected to the detachable sealing port 18. This connection method ensures the stability of the connection between the collection tank 20 and the inlet 17 and facilitates disassembly and maintenance. When the water flows into the collection tank 20 from the tunnel, the drive motor 13 in the monitoring tank 1 drives the rotating shaft 14 to rotate. The spiral conveying shaft 23, which is rotatably connected to the outer wall of the rotating shaft 14, is located inside the transport pipe 16. It can transport the water in the collection tank 20 upward through the transport pipe 16 for subsequent analysis and processing.
[0023] Preferably, an alarm 7 is fixedly attached to the upper surface of the mounting plate 3, a bracket 8 is fixedly attached to the upper surface of the mounting plate 3, a sliding rod 9 is movably connected inside the bracket 8, a sliding plate 10 is slidably connected to the outer wall of the sliding rod 9, a connecting rod 11 is fixedly attached to the lower surface of the sliding plate 10, and a buoyancy ball 15 is fixedly attached to the lower surface of the connecting rod 11. The alarm 7, as a key component of the alarm function of the entire device, will sound an alarm when it receives a trigger signal, reminding staff to be aware of the potential danger of water inrush in the water-rich tunnel. Furthermore, the upper surface of the mounting plate 3 is also fixedly attached to... The support frame 8 provides a foundational structure for supporting and installing subsequent components. A sliding rod 9 is movably connected inside the support frame 8, allowing relative movement within the frame and providing guidance and a track for the movement of the sliding plate 10. The sliding plate 10 is slidably connected to the outer wall of the sliding rod 9, allowing it to slide up and down along the outer wall. A connecting rod 11 is fixed to the lower surface of the sliding plate 10, connecting the sliding plate 10 and the buoyancy ball 15. The buoyancy ball 15 experiences buoyancy in water. When water seeps into the surrounding rock in the water-rich tunnel due to fracturing, the increased buoyancy on the buoyancy ball 15 causes the connecting rod 11 and the sliding plate 10 to slide upwards along the sliding rod 9. When the sliding plate 10 reaches a certain position, it triggers the alarm 7, thus achieving the monitoring and alarm function for water seepage caused by fracturing in the surrounding rock of the water-rich tunnel.
[0024] Preferably, a sealing plate 12 is fixedly connected to the inner wall of the monitoring tank 1. A drive motor 13 is fixedly connected to the upper surface of the sealing plate 12, and a rotating shaft 14 is rotatably connected to the lower surface of the drive motor 13. As the main part of the entire device, the sealing plate 12 fixed to the inner wall of the monitoring tank 1 serves to separate and protect the internal structure. It can prevent external factors such as water inflow from affecting the components installed above it, ensuring the normal operation of the device. The rotating shaft 14 is rotatably connected to the lower surface of the drive motor 13. When the drive motor 13 is working, it will drive the rotating shaft 14 to rotate. The rotating shaft 14 is connected to other components, which will subsequently drive the spiral conveyor shaft 23 and the rotating fan 24 to operate. The rotation of the rotating shaft 14 realizes the functions of water inflow transmission and processing. The rotating shaft 14 drives the spiral conveyor shaft 23 to rotate, which can transport the water in the collection box 20 to a designated location through the transport pipe 16 for analysis and detection. It drives the rotating fan 24 to rotate, which can perform certain operations such as stirring the water in the collection box 20, which helps to obtain water samples more evenly.
[0025] Preferably, the transport mechanism includes a transport pipe 16, which is located on the lower surface of the monitoring tank 1. An inlet 17 is fixedly connected to the lower surface of the transport pipe 16, and a detachable sealing port 18 is movably connected to the lower surface of the inlet 17. The transport pipe 16, located on the lower surface of the monitoring tank 1, is the core channel of the entire transport mechanism. Its main function is to carry and transport the gushing water collected from the water-rich tunnel. Secondly, the inlet 17, fixedly connected to the lower surface of the transport pipe 16, plays a receiving and guiding role. It can introduce the gushing water from the outside into the transport pipe 16 and is the key entrance for the gushing water to enter the transport channel. The detachable sealing port 18, movably connected to the lower surface of the inlet 17, has a dual function. On the one hand, during normal monitoring, it can maintain a sealed state to prevent external debris or other factors from entering the transport pipe 16 and affecting the transmission and subsequent analysis of the gushing water. On the other hand, when it is necessary to clean, maintain or replace the collection box 20, it can be easily disassembled for operation.
[0026] Preferably, a fixing bolt 19 is movably connected to one side wall of the detachable sealing port 18, and a collection box 20 is movably connected to the lower surface of the detachable sealing port 18. A fixing seat 21 is fixed to the outer wall of the collection box 20, and a mounting bracket 22 is fixed to the upper surface of the fixing seat 21. The fixing bolt 19 passes through the interior of the mounting bracket 22 and is connected to the detachable sealing port 18. The fixing bolt 19 plays a key role in fastening and disassembly. By rotating the fixing bolt 19, the detachable sealing port 18 can be connected or separated from other components. When it is necessary to install or fix the detachable sealing port 18, tighten the fixing bolt 19 to make it tightly connected to the corresponding component, ensuring the sealing and stability of the device. When it is necessary to maintain or clean the device, loosen the fixing bolt 19 to remove the detachable sealing port. The removable sealing port 18 is movably connected to a collection box 20 on its lower surface. The collection box 20 is used to collect water gushing from the water-rich tunnel. This movable connection allows the collection box 20 to be easily separated from the removable sealing port 18 when needed, facilitating the treatment of water samples in the collection box 20 or the replacement of a new collection box 20. A fixing seat 21 is fixed to the outer wall of the collection box 20, and a mounting bracket 22 is fixed to the upper surface of the fixing seat 21. The fixing seat 21 serves to support and fix the mounting bracket 22, while the mounting bracket 22 provides a through channel for the fixing bolts 19, enabling the fixing bolts 19 to firmly connect the removable sealing port 18 and the collection box 20 together. This structural design ensures the reliability and stability of the connection between the collection box 20 and the removable sealing port 18, while also facilitating disassembly and installation operations.
[0027] Preferably, a spiral conveyor shaft 23 is rotatably connected to the outer wall of the rotating shaft 14, and the spiral conveyor shaft 23 is located inside the transport pipe 16. A rotating fan 24 is rotatably connected to the outer wall of the rotating shaft 14, and the rotating fan 24 is located inside the collection box 20. When the drive motor 13 drives the rotating shaft 14 to rotate, the spiral conveyor shaft 23 will also rotate. The spiral structure of the spiral conveyor shaft 23 can transport the gushing water entering the transport pipe 16 upward along the transport pipe 16, realizing the function of gushing water transmission. In this way, the gushing water in the collection box 20 can be transported to a designated location, such as a place for water quality analysis or other treatment, which provides convenience for further research and treatment of the gushing water. The rotating shaft 14 is also rotatably connected to the outer wall of the rotating shaft 14, and the rotating fan 24 is located inside the collection box 20. Inside the collection box 20, when the drive motor 13 drives the rotating shaft 14 to rotate, the rotating fan 24 will also rotate inside the collection box 20. The rotation of the rotating fan 24 can stir the water in the collection box 20, making the water more uniform. The advantage of this is that when sampling and analyzing the water, more representative water samples can be obtained, improving the accuracy of the analysis results. At the same time, the rotation of the rotating fan 24 may also help prevent impurities in the water from settling at the bottom of the collection box 20, maintaining the fluidity of the water. Secondly, the spiral conveyor shaft 23 and the rotating fan 24 are both connected to the rotating shaft 14 and powered by the drive motor 13. They play different roles in their respective positions, but they cooperate with each other to complete the collection, transmission and preliminary treatment of the water. This structural design makes the entire monitoring and alarm device more functional and more effective in dealing with the situation of water inrush caused by rock fracture in water-rich roadways.
[0028] In use, the monitoring tank 1 is placed at a predetermined monitoring position in a water-rich roadway. The support plate 4 supports the monitoring tank 1 to ensure stability. Air is pumped into the airbag 2 via the air pump 5 and the air pipe 6. The buoyancy of the airbag 2 is adjusted according to the water level and flow conditions in the roadway to ensure the monitoring tank 1 remains stably suspended in a suitable position, guaranteeing the normal operation of subsequent monitoring work. If the surrounding rock in the water-rich roadway is not fractured, the device is in normal monitoring mode. The buoyancy ball 15 floats with the water level at the bottom of the roadway where water has accumulated. Since the water level has not risen, the sliding plate 10 is in its initial position on the sliding rod 9, and the alarm 7 is not triggered. At the same time, the drive motor 13 remains off, and the spiral transmission shaft 23 and the rotating fan 24 are stationary. When the surrounding rock fractures and water surges, the water level in the roadway rises rapidly, increasing the buoyancy of the buoyancy ball 15. This causes the connecting rod 11 and the sliding plate 10 to slide upwards along the sliding rod 9. When the sliding plate 10 slides to a specific position, the alarm 7 is triggered, immediately sounding an alarm to alert staff to the roadway flooding. In the event of a water inrush, and simultaneously with the alarm, water flows from the bottom of the tunnel through inlet 17 into transport pipe 16. The detachable sealing port 18 remains sealed to prevent debris from entering. The water flows along transport pipe 16 into collection tank 20 for temporary storage. The operator starts drive motor 13, which drives shaft 14 to rotate. Rotating fan 24 connected to the outer wall of shaft 14 rotates inside collection tank 20, stirring the water in the tank to make it more uniform, preventing impurities from settling, and facilitating the subsequent acquisition of representative water samples. Spiral conveyor shaft 23 connected to the outer wall of shaft 14 rotates inside transport pipe 16, transporting the water in collection tank 20 upwards along transport pipe 16 to a designated location for subsequent processing such as water quality analysis. Periodically, or when collection tank 20 needs cleaning or maintenance, the fixing bolt 19 is loosened to separate the detachable sealing port 18 from collection tank 20 to complete the corresponding operation. After the operation, the detachable sealing port 18 is reinstalled, and the fixing bolt 19 is tightened to ensure the sealing and stability of the device for continuous monitoring.
