Description

Technical Field

[0001] This invention relates to water level monitoring technology, specifically a mine water level monitoring device with dredging function. Background Technology

[0002] As is well known, in mine operations, a reservoir is typically installed connecting various small sluices to divert water seeping from these sluices into the reservoir. The water level in the reservoir must be monitored in real time, and intelligent flow sensors are installed in the connecting pipes between the sluices and the reservoir to monitor the amount of water flowing from the sluices to the reservoir. When the water level in a sluice increases suddenly, an alarm is triggered to alert maintenance personnel. When the water level in the reservoir is too high, a pump is activated to drain water and maintain the water level below a safe level to prevent safety risks. Currently, mine water level monitoring mainly relies on monitoring equipment to collect water level data and provide early warnings, ensuring the basic operation of the mine drainage system.

[0003] The shortcomings of existing technologies lie in their significant limitations. Current mine water level monitoring technologies are functionally limited, only capable of basic water level monitoring and drainage control. They cannot simultaneously clean silt from reservoirs, requiring manual entry into the underground reservoirs, which increases labor and time costs and poses safety risks, thus failing to meet the needs of intelligent coal mine construction. Furthermore, existing technologies lack designs to address the impact of silt accumulation. Silt buildup easily adheres to the monitoring rods and sensor surfaces, reducing water level measurement accuracy and potentially clogging drainage pipes, shortening the lifespan of monitoring equipment. Moreover, there is no technology adapted to different water levels. The dynamic adaptive mechanism requires additional power to control related actions, making it difficult to cope with scenarios with frequent fluctuations in the water level of the reservoir. It also lacks a protective structure for debris in the water, and debris can easily impact internal transmission components (such as turbines) during drainage, causing damage. In addition, the existing technology does not integrate the function of monitoring the operation status of the drainage pump. Staff cannot keep track of the pump's on / off status, whether it is overheating or operating abnormally in real time, making it difficult to detect and deal with equipment failures in a timely manner. This can easily affect the overall operational stability of the drainage system. Furthermore, simply draining water cannot effectively remove deposited sludge, and long-term accumulation will reduce the capacity of the reservoir, further reducing drainage efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a mine water level monitoring device with dredging function to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising: a monitoring body, wherein an intelligent detection sensor module is installed inside the monitoring body and mounted in a water storage tank via mounting components; further comprising:

[0006] A monitoring rod, which is fixedly installed below the monitoring unit and inserted into the water storage tank;

[0007] An upper sleeve and a lower sleeve are evenly spaced on the monitoring rod;

[0008] A buoyancy plate, which is movably installed on the outer periphery of the upper and lower sleeves;

[0009] The sliding mechanism is connected to the buoyancy plate. When the water contacts the buoyancy plate and generates buoyancy, causing it to slide upwards, the sliding mechanism passively opens the water intake port on the side of the lower sleeve of the buoyancy plate and connects with the magnetic mechanism. Utilizing the impact of the high-pressure water flow, the buoyancy plate is passively driven to rotate. At the same time, the stirring mechanism reduces the friction between the buoyancy plate and the upper sleeve. During the outward drainage process, the water in the reservoir is stirred simultaneously, mixing the sludge with the water before being discharged outwards.

[0010] As a further description of the above technical solution: the sliding mechanism includes a slot opened on the outer periphery of the lower sleeve, a slot slidably connected to a pin, and a water inlet communicating with the inside of the lower sleeve is opened inside the slot. The end of the water inlet corresponds to both sides of the turbine, and the turbine is rotatably installed inside the lower sleeve.

[0011] As a further description of the above technical solution: the bottom end of the turbine is rotatably connected to the protective cover via a mounting rod. The protective cover is fixedly installed in the bottom of the lower sleeve in an inverted cone shape. The larger end of the protective cover is connected to the inner side wall of the lower sleeve and has a drainage hole.

[0012] As a further description of the above technical solution: the magnetic mechanism includes a hollow magnetic ring fixedly disposed at the center of the buoyancy plate, and a locking post is movably installed on the inner side of the magnetic ring by means of a stirring mechanism. The magnetic post is movably sleeved on the outer side of the upper sleeve and the lower sleeve.

[0013] As a further description of the above technical solution: the magnetic mechanism also includes a magnetic rod fixedly installed on the upper end face of the turbine, and the radial magnetic field of the magnetic poles on the surface of the magnetic rod is stronger than the axial magnetic field.

[0014] As a further description of the above technical solution: the stirring mechanism includes a lever rotatably mounted on the lower end face of the buoyancy plate via a torsion spring shaft. Multiple sets of levers are provided. The lever closest to the center of the buoyancy plate is inserted into the interior of the buoyancy plate. One end of the lever is connected to one end of a connecting rod via a torsion spring shaft. The other end of the connecting rod is connected to the back of the movable plate via a torsion spring shaft. A locking post is fixedly connected at the longitudinal center line of the front of the movable plate. The four corners of the back of the movable plate are connected to the inner wall of the magnetic ring via return springs.

[0015] As a further description of the above technical solution: a frosted plate is provided on the outer periphery of the upper sleeve at the position corresponding to the slot of the lower sleeve.

[0016] As a further description of the above technical solution: the paddle mounted on the lower end face of the buoyancy plate is initially tilted and open in the direction of rotation of the buoyancy plate, and the tilt angle is less than 30°. The paddle is unfolded by the resistance of the water as the buoyancy plate rotates, and the unfolding angle is less than 90°.

[0017] As a further description of the above technical solution: the buoyancy plate is subject to a greater buoyancy force from the water than the frictional force of the locking pin in the slot, plus the axial magnetic attraction between the magnetic ring and the magnetic pin.

[0018] As a further description of the above technical solution: the weight of the buoyancy plate itself is greater than the friction between the pin and the frosted plate, the pin slot, and the axial magnetic attraction between the external magnetic ring and the magnetic pin.

[0019] In the above technical solution, the mine water level monitoring device with dredging function provided by the present invention has the following beneficial effects:

[0020] 1. Automatic stirring and sludge removal, reducing costs, improving efficiency and promoting intelligentization: The device uses high-pressure water flow to impact the turbine, which drives the buoyancy plate to rotate. With the help of the paddle wheel to stir the water, the sludge in the water tank can be stirred and diluted into mud. When draining, some coal sludge is removed at the same time. There is no need for manual sludge removal, saving manpower and time costs and promoting the improvement of the level of intelligent construction in coal mines.

[0021] 2. Real-time water level monitoring for unmanned and safe operation: It can monitor the water level data of the small water pool in the well in real time, accurately measure the water level height and changes; when the water level reaches the system set height, it automatically triggers the water pump start command, and when the water level drops, it automatically stops the drainage pump, ensuring that the water level is always within a safe range, without the need for manual intervention.

[0022] 3. Monitor the status of the drainage pump to ensure stable operation of the equipment: The operation status of the drainage pump, such as its on / off state, can be monitored in real time. Staff can keep track of the equipment's working status at any time through the monitoring data, which can help to detect faults or abnormal operation problems such as pump overheating or abnormal shutdown in a timely manner, and deal with them in time to avoid equipment damage or affecting drainage operations.

[0023] 4. High degree of functional integration and simplified operation process: It integrates water level monitoring, automatic drainage control, silt cleaning and equipment status monitoring into one unit, eliminating the need for additional equipment configuration, simplifying the mine drainage and monitoring operation process, and reducing equipment installation and maintenance costs.

[0024] 5. Comprehensive protection design extends equipment life: The inverted conical protective cover at the bottom of the lower casing can block debris in the water from impacting the turbine and avoid damage to components; at the same time, the sludge removal function prevents sludge from adhering to the monitoring components, ensuring sensor sensitivity and extending the overall service life of the equipment.

[0025] 6. Adapts to water level changes and fits dynamic scenarios: The buoyancy plate slides adaptively along the casing as the water level rises and falls. When the water level reaches the standard, it automatically triggers dredging and drainage actions. After the water level drops, it resets by its own gravity without the need for additional power control, making it suitable for use scenarios where the water level of mine reservoirs changes dynamically.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Please see Figures 1-8 This invention provides a technical solution for a mine water level monitoring device with dredging function: It includes a monitoring body 1, which houses an intelligent detection sensor module and is installed in a water storage tank via a mounting component 2; it also includes:

[0039] Monitoring rod 3 is fixedly installed below the monitoring body 1 and inserted into the water storage tank;

[0040] Upper sleeve 5 and lower sleeve 10 are evenly spaced on monitoring rod 3;

[0041] Buoyancy plate 4 is movably installed on the outer periphery of upper sleeve 5 and lower sleeve 10;

[0042] The sliding mechanism is connected to the buoyancy plate 4. When the water contacts the buoyancy plate 4 and generates buoyancy, the sliding mechanism passively opens the water intake port 11 on the side of the lower sleeve 10 of the buoyancy plate 4 and connects with the magnetic mechanism. The impact of the high-pressure water flow passively drives the rotation of the buoyancy plate 4. At the same time, the stirring mechanism reduces the friction between the buoyancy plate 4 and the upper sleeve 5. During the process of draining water, the water in the reservoir is stirred at the same time, and the sludge is mixed with the water and discharged outward.

[0043] Water storage tanks are typically installed in mines to connect various small water pockets in the mine. Water seeping from the small water pockets is discharged into the storage tanks, and the water level in the storage tanks is monitored in real time. Intelligent flow sensors are also installed in the connecting pipes between each small water pocket and the storage tank to monitor the amount of water discharged from the small water pockets into the storage tanks in real time. When the water volume in a small water pocket suddenly increases, an alarm is triggered, prompting maintenance personnel to inspect and maintain the corresponding small water pocket. Furthermore, if the water level in the storage tank becomes too high, the water pump is automatically activated to pump water out of the storage tank, ensuring that the water level in the storage tank remains below the safe water level line and preventing danger caused by excessively high water levels.

[0044] Meanwhile, the monitoring unit 1 can monitor the operating status of the drainage pump equipment in real time, including the equipment's on / off status. Through this data, staff can understand the equipment's working condition at any time, promptly detect equipment malfunctions or abnormal operating conditions, such as pump overheating or other abnormalities, and address them in a timely manner.

[0045] When using the monitoring equipment, first install the monitoring equipment in the water storage tank using the mounting component 2. Place the monitoring body 1, which has a sensor module inside, at the top of the monitoring equipment at the top of the water storage tank. The mounting component 2 can be fixed to the water storage tank using a welded square tube, or it can be installed using an existing bracket. The mounting component 2 can use any of the existing fixing methods, which will not be elaborated on here. After fixing the monitoring body 1 above the water storage tank using the mounting component 2, the long monitoring rod 3 with an intelligent water level sensor inside, which is connected to the bottom of the monitoring body 1, is inserted into the water storage tank. The intelligent water level sensor is installed in the monitoring rod 3 and connected to the sensor module inside the monitoring body 1 to monitor and warn of the water level in the water storage tank in real time.

[0046] In another embodiment of the present invention, preferably, the sliding mechanism includes a slot 12 formed on the outer periphery of the lower sleeve 10, a slot 8 slidably connected in the slot 12, and a water inlet 11 connected to the inside of the lower sleeve 10 is formed inside the slot 12. The end of the water inlet 11 corresponds to both sides of the turbine 16, and the turbine 16 is rotatably installed inside the lower sleeve 10.

[0047] In another embodiment of the present invention, the bottom end of the turbine 16 is rotatably connected to the protective cover 17 via a mounting rod. The protective cover 17 is fixedly installed in the bottom of the lower sleeve 10 in an inverted cone shape. The larger end of the protective cover 17 is connected to the inner side wall of the lower sleeve 10 and has a drainage hole.

[0048] In another embodiment of the present invention, the buoyancy of the buoyancy plate 4 is greater than the friction of the locking post 8 in the locking groove 12, plus the axial magnetic attraction between the magnetic ring 7 and the magnetic post.

[0049] In another embodiment of the present invention, the weight of the buoyancy plate 4 itself is greater than the friction between the locking post 8 and the frosted plate 9 and the locking groove 12, and the axial magnetic attraction between the external magnetic ring 7 and the magnetic post.

[0050] After the water in the small puddle flows into the reservoir, the water level in the reservoir rises. When the water level submerges the buoyancy plate 4 movably mounted on the monitoring rod 3, the buoyancy exerted by the water on the buoyancy plate 4 exceeds its own weight and the friction between the magnetic ring 7 inside the buoyancy plate 4 and the lower sleeve 10 and upper sleeve 5. Therefore, the buoyancy causes the buoyancy plate 4 to slide upwards from the surface of the lower sleeve 10 and gradually fit onto the outside of the upper sleeve 5. Figure 2 and 5 In the middle, S1 is the position of the buoyancy plate 4 and the position of the locking post 8 set inside the magnetic ring 7 when the water level does not submerge the buoyancy plate 4; S2 is the position of the buoyancy plate 4 and the position of the locking post 8 after the water level submerges the buoyancy plate 4.

[0051] When the water level in the reservoir is low, the water from the small puddles gradually flows into the reservoir, submerging the buoyancy plates 4 on the surface of the monitoring rod 3 from bottom to top. When the water level touches the buoyancy plates 4, and as the water level gradually rises, the buoyancy of the water on the buoyancy plates 4 causes them to gradually slide upwards on the lower sleeve 10. At this time, the inner side of the magnetic ring 7 at the center of the buoyancy plates 4 slides upwards through the locking pins 8 set on the movable plate 14 from the locking grooves 12 set on the outer periphery of the lower sleeve 10 until the buoyancy plates 4 are completely submerged and the water level is higher than the upper end of the corresponding upper sleeve 5. At this point, the water completely submerges the buoyancy plates 4, and the buoyancy plates 4 are located on the upper sleeve 5. At the end position, and the magnetic ring 7 at the center of the buoyancy plate 4 is completely separated from the lower sleeve 10. In this state, the locking pin 8 is completely pulled out from the locking groove 12 and contacts the frosted plate 9 on the surface of the upper sleeve 5 corresponding to the position of the locking pin 8. At this time, the frosted plate 9 restricts the movement of the locking pin 8 by friction with the locking pin 8. The locking groove 12 is provided with a water inlet 11 that connects to the inside of the lower sleeve 10. Therefore, the water flows through the water inlet 11 into the lower sleeve 10, the upper sleeve 5 and the monitoring rod 3. At this time, since the water flows in by itself through the water inlet 11, the impact force of the water flow on the turbine 16 is less than the friction force between the frosted plate 9 and the locking pin 8. Therefore, the turbine 16 will not rotate.

[0052] When the water level in the reservoir is too high, the intelligent water level sensor inside the monitoring rod 3, in conjunction with the sensor module inside the monitoring body 1, controls the activation of the water pump to drain the water from the reservoir. During the pumping process, as the water pump draws water out through the inside of the monitoring rod 3, the water flow entering the lower sleeve 10 through the inlet impacts the turbine 16, combined with the attached... Figure 6 As shown, since the water inlets are located on both sides of the lower sleeve 10 and the ends of the water inlets are directly facing the fan blades on both sides of the turbine 16, and in accordance with the shape of the turbine 16, the fast water flow sucked in by the water inlets will impact both sides of the turbine 16, thereby causing the turbine 16 to rotate clockwise. At the same time as the turbine 16 rotates, since the submerged buoyancy plate 4 is completely fitted on the outside of the upper sleeve 5, the magnetic ring 7 and the magnetic rod 15 connected to the turbine 16 are magnetically connected.

[0053] In another embodiment of the present invention, the magnetic mechanism includes a hollow magnetic ring 7 fixedly disposed at the center of the buoyancy plate 4, a locking post 8 being movably installed inside the magnetic ring 7 by means of a stirring mechanism, and the magnetic post being movably sleeved on the outside of the upper sleeve 5 and the lower sleeve 10.

[0054] In another embodiment of the present invention, the magnetic mechanism further includes a magnetic rod 15 fixedly installed on the upper end face of the turbine 16, wherein the radial magnetic field of the magnetic poles on the surface of the magnetic rod 15 is stronger than the axial magnetic field.

[0055] There are four points to consider here:

[0056] 1. The way in which the magnetic rod 15 and the magnetic ring 7 transmit torque using magnetism is essentially "magnetic coupling transmission": the magnetic parts of the magnetic rod 15 and the magnetic ring 7 form a stable magnetic field that interacts with each other (for example, the corresponding positions of the magnetic rod 15 and the magnetic ring 7 are opposite magnetic poles). When the magnetic rod 15 rotates, the attractive / repulsive force of the magnetic field will drive the magnetic ring 7 to rotate synchronously. The magnetic pole distribution of the magnetic rod 15 and the magnetic ring 7 are corresponding, both being multi-pole ring arrangements.

[0057] 2. Both the upper sleeve 5 and the lower sleeve 10 are made of non-magnetic materials (such as plastic, ceramic, etc.), and will not shield or weaken the magnetic field;

[0058] 3. In order to enable the magnetic ring 7 to slide up and down on the outer periphery of the upper sleeve 5 and lower sleeve 10 outside the magnetic rod 15, the magnetic poles on the surface of the magnetic rod 15 are mainly distributed radially (in combination with...). Figure 6 The horizontal position is relatively weak, and the axial (vertical) magnetic field is relatively weak to avoid strong axial magnetic attraction that hinders sliding.

[0059] 4. The magnetic pole strength between the magnetic rod 15 and the magnetic ring 7 is sufficient to offset the magnetic field attenuation caused by the gap between the upper sleeve 5 and the lower sleeve 10, while matching the load requirements for transmitting torque.

[0060] By using the above four points, magnetic transmission between the magnetic rod 15 and the magnetic ring 7 can be ensured;

[0061] In another embodiment of the present invention, the stirring mechanism includes a paddle that is rotatably mounted on the lower end face of the buoyancy plate 4 via a torsion spring shaft 19. Multiple paddles 13 are provided. The paddle 13 that is closest to the center of the buoyancy plate 4 is inserted into the buoyancy plate 4. One end of the paddle 13 is connected to one end of the connecting rod 18 via the torsion spring shaft 19. The other end of the connecting rod 18 is connected to the back of the movable plate 14 via the torsion spring shaft 19. The locking post 8 is fixedly connected at the longitudinal center line of the front of the movable plate 14. The four corners of the back of the movable plate 14 are connected to the inner wall of the magnetic ring 7 via a return spring 6.

[0062] In another embodiment of the present invention, a frosted plate 9 is provided on the outer periphery of the upper sleeve 5 at the position corresponding to the slot 12 of the lower sleeve 10.

[0063] In another embodiment of the present invention, preferably, the paddle 13 rotatably mounted on the lower end face of the buoyancy plate 4 is initially tilted and open in the direction of rotation of the buoyancy plate 4, and the tilt angle is less than 30°. The paddle 13 is unfolded by the resistance of the water as the buoyancy plate 4 rotates, and the unfolding angle is less than 90°.

[0064] The turbine 16 rotates due to the impact of the rapidly flowing water, which in turn drives the magnetic rod 15 to rotate. The magnetic rod 15 then drives the magnetically driven ring 7 to rotate the buoyancy plate 4. Initially, the buoyancy plate 4 rotates slowly because the locking pin 8 is still in contact with the surface of the upper sleeve 5. During rotation, combined with the attached... Figure 4 , 5 7 and 8, during the rotation of buoyancy plate 4, located on the attached Figure 7 In the initial state A, the buoyancy plate 4 has an outwardly inclined opening of the lever 13, with the opening facing the direction of rotation of the buoyancy plate 4. Therefore, after the buoyancy plate 4 rotates, the water flow impacts the buoyancy plate 4, switching the lever 13 from the initial state A (inclined) to the state B (lever 13 fully open). Under the rotation of the torsion spring shaft 19, the lever 13 drives the connecting rod 18 connected to the bottom end through the torsion spring shaft 19, which pulls the movable plate 14, which is movably installed on the inner side of the magnetic ring 7 through the return spring 6, to slide towards the outer periphery of the magnetic ring 7. This separates the locking post 8 from the outer surface of the upper sleeve 5, thereby reducing the friction of the magnetic ring 7 sliding on the outer periphery of the upper sleeve 5, which facilitates the rotation of the buoyancy plate 4.

[0065] The rotation of the buoyancy plate 4, in conjunction with the unfolded paddle 13 below, mixes and agitates the water in the reservoir, stirring and diluting the sludge in the reservoir into a slurry. This allows for the removal of some coal sludge from the reservoir while draining water, replacing manual sludge removal and saving labor and time. After the water level drops and the buoyancy plate 4 separates, the paddle 13 returns to its original position under the action of the torsion spring shaft 19. Simultaneously, the movable plate 14 drives the locking pin 8 to return to its original position under the action of the return spring 6, thus bringing the locking pin 8 into contact with the outer surface of the upper sleeve 5. A grinding wheel is then installed on the outer circumference of the upper sleeve 5. The sand plate 9 is designed to increase the friction when the locking pin 8 rotates to the sand plate 9, ensuring that when the locking pin 8 stops rotating with the magnetic ring 7, it stays on the surface of the sand plate 9, corresponding to the position of the slot 12 on the outer periphery of the lower sleeve 10. Furthermore, the weight of the buoyancy plate 4 itself is greater than the friction between the sand plate 9, the slot 12 and the locking pin 8, as well as the magnetic attraction / repulsion between the magnetic rod 15 and the magnetic ring 7. Therefore, under the action of gravity, the magnetic ring 7 drives the buoyancy plate 4 to slide down from the surface of the upper sleeve 5 to the surface of the lower sleeve 10, resetting to the initial position.

[0066] An additional situation exists here: the water level in the reservoir raises the buoyancy plate 4 to a height between the upper sleeve 5 and the lower sleeve 10. At this time, the magnetic ring 7 is located at the connection between the upper sleeve 5 and the lower sleeve 10, while one end of the locking pin 8 is still inserted in the locking groove 12, and the other end contacts the frosted plate 9. At this time, the water inlet in the lower locking groove 12 can flow water, but even if the sucked water impacts the turbine 16, the locking pin 8, because it is inserted in the locking groove 12, acts in the opposite direction on the turbine 16, thus restricting the rotation of the turbine 16 and also restricting the rotation of the buoyancy plate 4. The buoyancy plate 4 at this position is still stationary and cannot rotate.

[0067] Combined with appendix Figure 6 In the middle, the protective cover 17 at the bottom of the lower sleeve 10 is inverted conical in shape, and a drain hole is provided at the end with the larger size that connects to the inner wall of the lower sleeve 10. This can not only ensure the flow of water in the water tank inside the monitoring rod 3, but also prevent debris in the water from impacting the turbine 16 and causing damage to the turbine 16 during the drainage process. In addition, the drain hole at the end of the protective cover 17 can also be used to allow the upward impacting high-pressure water flow to impact the blades of the turbine 16, thereby accelerating the rotation speed of the turbine 16.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
