Description

Technical Field

[0001] The invention relates to the field of mine safety devices, in particular to a gold mine safety monitoring device. Background Art

[0002] During underground mine operations, due to the complex underground environment, emergencies may occur at any time during the work process, such as water gushing, flammable gas leakage, shaft wall collapse, etc. In order to improve the safety of underground operations, regular inspections are usually carried out along the mine tunnels, or special monitoring devices are installed in the mine tunnels to improve the safety of underground operations.

[0003] For related technologies, please refer to the Chinese patent with announcement number CN220267776U, which discloses a water seepage monitoring device for coal mine safety, including a box body, air holes are opened on both sides of the front and back of the box body, a group of anti-collision plates are connected to the bottom of the box body, and a plurality of first through holes are opened at both ends of the anti-collision plates. A connecting rod is connected inside the first through hole, one end of the connecting rod is fixedly connected to the box body, and a spring is connected to the outside of the connecting rod. When the box body falls to the ground, the anti-collision plate contacts the ground at the first time. Through the elastic action of the spring, it is helpful to buffer part of the impact force acting on the anti-collision plate, reduce the impact on the inside of the box body, and play an effect of protecting the electrical components inside the box body.

[0004] Regarding the above-mentioned related technologies, for underground operations, due to factors such as abundant groundwater content and poor air fluidity, the water vapor content in the air in the mine tunnel is relatively high. In addition, due to the lack of light in the mine, the temperature of the inner wall of the mine tunnel is relatively low, which will cause the moisture in the air to condense into water droplets on the inner wall of the mine tunnel and gather into strands. When monitoring the mine tunnel, if the monitoring device is installed on the side wall of the mine tunnel for a long time, when the condensed water flows through the probe position on the monitoring device, it is easy to cause the monitoring device to be triggered, thereby affecting the accuracy. If the condensed water is cleaned regularly, it will take a lot of time, making the monitoring process more inconvenient. Summary of the invention

[0005] In order to improve the ease of use of a monitoring device, the present application provides a gold mine safety monitoring device.

[0006] The present application provides a gold mine safety monitoring device, which adopts the following technical solution: A gold mine safety monitoring device comprises a fixed rod and a water seepage sensor, wherein the water seepage sensor is fixedly arranged at one end of the fixed rod, and when the amount of water in the working range of the water seepage sensor reaches a preset value, the water seepage sensor is triggered and an alarm is sounded, the fixed rod is hollow, and a top block is fixedly arranged at one end of the fixed rod, and a water collecting box is arranged at the other end, the water collecting box is located on the outer surface of the fixed rod, and the water collecting box is connected to the fixed rod, the water seepage sensor is used to monitor the amount of water accumulated in the water collecting box, and the fixed rod is provided with a plurality of water inlets along the length direction, and the water inlets are located at one side of the fixed rod away from the water collecting box. The side is connected with the inner cavity of the fixed rod, and a plurality of plug blocks are arranged inside the fixed rod along the axial direction, and the plug blocks correspond to the water inlet one by one. The fixed rod is fixed with a guide block for guiding the plug block to move radially along the fixed rod, and a moving rod is slidably connected inside the fixed rod along the axial direction. When the moving rod is working, it drives the plug block to extend or retract from the water inlet. The guide block is provided with a guide groove, and the plug block is fixedly connected with a slider sliding along the guide groove. When the plug block is located in the fixed rod and moves toward the axis of the fixed rod, the guide groove guides the slider to move radially along the fixed rod, so that the plug block avoids the water inlet.

[0007] By adopting the above technical solution, when working, one end of the fixed rod with the top block is inserted into the inner wall of the mine tunnel, and the water collecting box is tilted toward the ground relative to the top block. At this time, the water inlet is at the upper end of the top rod, and the water collecting box is at the end of the fixed rod near the ground. In the initial state, all the plugs are located in the fixed rod, and the plugs are pushed out of the water inlet by the moving rod. Under the action of the guide block, the plug squeezes and breaks the rock wall of the mine tunnel, so that cracks are formed in the rock wall of the mine tunnel. After the squeezing operation is completed, the plug is driven to be recovered by the moving rod. Under the cooperation of the guide groove and the slider, the plug enters the fixed rod and moves along the axis direction of the fixed rod. At this time, the plug avoids the water inlet. When water seepage occurs in the mine tunnel, it spreads from the inner layer of the mine tunnel to the outer layer. Under the guidance of the cracks squeezed by the plug, the seepage water enters the fixed rod along the water inlet and flows to the water collecting box under the action of gravity. When the water seepage sensor is triggered, it means that water seepage occurs inside the inner wall of the mine tunnel. The water seepage sensor only monitors the water seepage inside the inner wall of the mine tunnel. The condensed water on the inner wall of the mine tunnel is not easy to penetrate into the inner layer of rock and soil, which helps to reduce the interference of condensed water on the water seepage sensor. During the summer monitoring process, there is no need to frequently clean the condensed water, which improves the convenience of use and monitoring accuracy of the monitoring device.

[0008] Optionally, the plug block includes an active block and a driven block, the active block is fixedly provided with a sliding rod arranged along the axial direction of the fixed rod, the sliding rod passes through the driven block and is slidably connected to the driven block, the same group of plug blocks corresponds to two guide blocks, the two guide blocks are radially distributed along the fixed rod, the active block and the driven block are both located between the two guide blocks and fit with the two guide blocks, two groups of guide grooves are provided and are located on the side of the guide block close to the active block, the two groups of guide grooves are mirrored, two groups of sliders are also provided, the two groups of sliders are respectively fixed to the active block and the driven block, when the slider moves along the guide groove toward the water inlet, the active block and the driven block approach each other until they fit together, when the slider moves toward the end of the guide groove away from the water inlet, the active block and the driven block move away from each other, and the moving rod is used to drive the active block to move radially along the fixed rod.

[0009] By adopting the above technical solution, under the connection of the sliding rod, when the moving rod drives the active block to move along the radial direction of the fixed rod, the active block drives the driven block to move synchronously. By setting two opposing guide grooves, under the cooperation of the corresponding sliders, the active block and the driven block gradually separate when moving toward the axis of the fixed rod, which facilitates the infiltration water to pass between the active block and the driven block. While keeping the size of the water inlet unchanged, the moving distance of a single plug in the direction of the axis of the fixed rod is reduced, thereby facilitating the reduction of the installation space, improving the overall structural compactness of the fixed rod, and enhancing the installation convenience of the fixed rod.

[0010] Optionally, a hydraulic connecting cylinder is fixedly provided at one end of the fixed rod away from the top block, and the hydraulic connecting cylinder is used to connect an external hydraulic system. Two movable rods are provided, and the two movable rods are slidably connected to the fixed rod along the axial direction of the fixed rod. When the hydraulic connecting cylinder is working, it drives the two movable rods to move, and the water inlet is directly opposite to the gap between the two movable rods. A plurality of pushing blocks are arranged along the length direction of the movable rod, and the pushing block is in contact with the end face of the active block facing away from the water inlet. When the pushing block approaches the top block, the active block is pushed to extend out from the water inlet. A rotating rod corresponding to the active block is fixed between the two movable rods, and a hanging rod is hinged on the side of the active block facing away from the driven block. The rotating rod is located on the side of the hanging rod close to the driven block, and a hanging interface for connecting the rotating rod is provided at the lower end of the hanging rod.

[0011] By adopting the above technical solution, an external hydraulic system is connected through a hydraulic connecting tube, and the hydraulic system is used as the power source of the moving rod, which is beneficial to improving the moving stability of the moving rod. When the moving rod approaches the top block, the active block is driven to extend from the water inlet through the pushing block. At this time, the rotating rod moves in the direction away from the hanging rod. When the moving rod is away from the top block, the rotating rod enters the hanging interface. At this time, the pushing block is separated from the active block, and the top rod continues to move away from the top block, so that the rotating rod applies a pulling force to the hanging rod through the hanging interface. Under the guiding action of the guide groove, the active block is close to the axis of the fixed rod and separated from the driven block.

[0012] Optionally, the active block and the driven block are both vertically slidably connected to a material box on one side away from each other, the upper end of the material box is in contact with the inner wall of the fixed rod, and the material box is slidably connected to the fixed rod along the axial direction of the fixed rod, the upper ends of the active block and the driven block are both provided with inclined surfaces close to each other, and the material box is provided with a feed port facing the inclined surfaces.

[0013] By adopting the above technical solution, before the active block and the driven block enter the drain outlet and separate from each other, the rock and soil squeezed and crushed by the active block and the driven block falls toward the fixed rod under the action of gravity, and then falls into the material box from the feed port under the action of the inclined surface, which helps to reduce the probability of fine rock and soil entering the fixed rod and affecting the operation of the monitoring device.

[0014] Optionally, the fixed rod is provided with water collecting ports on both sides along the horizontal direction, the water collecting ports are arranged along the length direction of the fixed rod and are connected with the inner cavity of the fixed rod, and an avoidance groove connected with the water collecting ports is arranged along the length direction at one end of the fixed rod close to the water inlet, and a plurality of arc plates are arranged in the avoidance groove, the arc plates are fixedly connected to the fixed rod, and the outer diameter of the arc plates is the same as the outer diameter of the fixed rod.

[0015] By adopting the above technical solution, after the fixed rod is inserted into the mine tunnel, the arc plate cooperates with the rock and soil in the mine tunnel to support and position the fixed rod, and the gap between adjacent arc plates constitutes a channel. When the infiltration position of the seepage water is not directly opposite to the water inlet, the seepage water contacts the inner wall of the avoidance groove and flows toward the water collection port along the gap between adjacent arc plates. Finally, the seepage water passes through the water collection port and enters the fixed rod, which is beneficial to improve the monitoring range and enhance the monitoring accuracy.

[0016] Optionally, the fixed rod is fixedly connected with a plurality of guide blocks along the length direction, all the guide blocks are located in the water collection port and arranged along the length direction of the water collection port, all the guide blocks are fixedly connected to the inner wall of the water collection port at one end close to the water inlet, and the diameter of the guide block gradually decreases in the direction away from the water inlet, and two oppositely arranged guide strips are fixedly connected between adjacent guide blocks, and the guide strips gradually deviate from the direction close to the guide block to the direction away from the water inlet.

[0017] By adopting the above technical solution, when the infiltrated water flows to the water collection port, the guide block is used to accelerate the probability of the infiltrated water gathering and dripping, which is beneficial to improving the monitoring efficiency. At the same time, the guide strip guides the infiltrated water to flow toward the guide block, further improving the gathering efficiency of the infiltrated water.

[0018] Optionally, a sealing plate for sealing the water collection port is hinged inside the fixed rod, and a torsion spring is provided between the sealing plate and the fixed rod. When the torsion spring is in a natural state, the sealing plate is located in the water collection port and seals the water collection port. A contact block is fixedly provided on the side of the sealing plate close to the axis of the fixed rod, and an arc-shaped surface is provided on the side of the contact block close to the top block. The movable rod is fixedly connected to a top rod corresponding to the contact block, and when the top rod contacts the arc-shaped surface, it drives the contact block to move toward the axis of the fixed rod.

[0019] By adopting the above technical solution, in the initial state, the sealing plate blocks the water collection port, thereby reducing the external rock and soil entering the water collection port during the installation of the fixed rod. When the installation of the fixed rod is completed and the moving rod drives the active block and the driven block to be recovered, the push rod gradually approaches the contact block. When the push rod contacts the arc surface of the contact block, it drives the contact block close to the axis of the fixed rod. At this time, the contact block drives the sealing plate to rotate, so that the water collection port is opened.

[0020] Optionally, the water collecting box is provided with a drain outlet, and the water collecting box is slidably connected to a block for blocking the drain outlet. An opening and closing motor for driving the block to move is fixedly provided at the lower end of the water collecting box. The water seepage sensor includes a probe, an alarm and a sensor. The sensor is fixedly arranged at the end of the fixed rod away from the top block. The probe is located in the water collecting box and is electrically connected to the sensor. When the probe contacts the accumulated water, the sensor is triggered. The opening and closing motor is electrically connected to the sensor. The sensor has a secondary triggering state when working. When the sensor is triggered for the first time, the opening and closing motor drives the block to move back and forth. After the accumulated water is discharged, the block is reset and waits for the sensor to be triggered for the second time. When the secondary triggering time of the sensor is lower than a preset value, the alarm sounds an alarm.

[0021] By adopting the above technical solution, when working in summer, there is a probability that the air inside the fixed rod will condense. At this time, the condensed water will gather in the water collection box under the action of gravity and trigger the sensor for the first time through the probe. At this time, the opening and closing motor drives the block to move, and then discharges the condensed water through the drain port. The time required for the condensed water to gather again is longer than the speed of the infiltration water. When the condensed water gathers again and triggers the sensor, the time for the sensor to be triggered again is higher than the preset value. At this time, the alarm is not triggered. When the rock wall of the mine tunnel seeps, the speed at which the infiltration water gathers twice in the water collection box is relatively fast, which causes the sensor to be triggered continuously and the alarm sounds, which is conducive to reducing the probability of false touch of the sensor and further improving the monitoring accuracy.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. During operation, insert one end of the top block of the fixed rod into the inner wall of the mine tunnel, and tilt the water collecting box toward the ground relative to the top block. At this time, the water inlet is at the upper end of the top rod, and the water collecting box is at the end of the fixed rod near the ground. In the initial state, all the plugs are located inside the fixed rod. The plugs are pushed out of the water inlet by the moving rod. Under the action of the guide block, the plugs squeeze and break the rock wall of the mine tunnel, so that cracks are formed on the rock wall of the mine tunnel. After the squeezing operation is completed, the plugs are driven to be recovered by the moving rod. Under the cooperation of the guide groove and the slider, the plugs enter the fixed rod and move along the axis of the fixed rod. At this time, the plugs avoid the water inlet. When water seepage occurs in the mine tunnel, it spreads from the inner layer of the mine tunnel to the outer layer. Under the guidance of the cracks squeezed by the plugs, the infiltrated water enters the fixed rod along the water inlet and flows to the water collecting box under the action of gravity. When the water seepage sensor is triggered, it means that water seepage occurs inside the inner wall of the mine tunnel. The water seepage sensor only monitors the water seepage inside the inner wall of the mine tunnel. The condensed water on the inner wall of the mine tunnel is not easy to penetrate into the inner layer of rock and soil, which is conducive to reducing the interference of condensed water on the water seepage sensor. During the summer monitoring process, there is no need to frequently clean up the condensed water, which improves the convenience of use and monitoring accuracy of the monitoring device; 2. When working in summer, there is a probability that the air inside the fixed rod will condense. At this time, the condensed water will gather in the water collection box under the action of gravity and trigger the sensor for the first time through the probe. At this time, the opening and closing motor drives the block to move, and then discharges the condensed water through the drain port. The time required for the condensed water to gather again is longer than the speed of the infiltration water. When the condensed water gathers again and triggers the sensor, the time for the sensor to be triggered again is higher than the preset value. At this time, the alarm will not be triggered. When infiltration occurs in the rock wall of the mine tunnel, the speed at which the infiltration water gathers twice in the water collection box is relatively fast, which causes the sensor to be triggered continuously and the alarm sounds, which is conducive to reducing the probability of false touch of the sensor and further improving the monitoring accuracy.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] The embodiment of the present application discloses a gold mine safety monitoring device.

[0032] Example: Reference Figure 1 and Figure 2 A gold mine safety monitoring device includes a hollow fixed rod 1, one end of the fixed rod 1 along the axial direction is fixedly connected to a top block 10, and the other end is fixedly provided with a water collecting box 11, which is located on the outer surface of the fixed rod 1 and communicates with the inner cavity of the fixed rod 1. When in use, a hole matching the fixed rod 1 needs to be opened on the inner wall of the mine tunnel, and then one end of the fixed rod 1 with the top block 10 is inserted into the hole, and at this time, the water collecting box 11 is located at the end of the fixed rod 1 near the ground.

[0033] Reference Figure 3 and Figure 4 , a plurality of water inlets 12 are radially opened on the side of the fixed rod 1 away from the water collecting box 11. In the working state, the water inlets 12 are located on the side of the fixed rod 1 away from the ground, and all the water inlets 12 are located in the inner layer of the inner wall of the mine tunnel. An insert block corresponding to the water inlets 12 is arranged inside the fixed rod 1. The insert block includes an active block 31 and a passive block 32. At any water inlet 12, the passive block 32 is located on the side of the active block 31 close to the top block 10, and a sliding rod 311 is fixed on the side of the active block 31 close to the passive block 32. The sliding rod 311 passes through the passive block 32 and is slidably connected to the passive block 32. Under the connection action of the sliding rod 311, the active block 31 moves along the radial direction of the fixed rod 1, driving the passive block 32 to move synchronously. A spring 312 is fixedly connected between the sliding rod 311 and the passive block 32. The spring 312 applies a thrust to the passive block 32 in the direction pointing to the active block 31.

[0034] Reference Figure 5 and Figure 6 , fixing rod 1 (reference Figure 1 ) at the water inlet 12 (reference Figure 1 ) is fixedly provided with a guide block 4, and two guide blocks 4 are provided at the same water inlet 12. The active block 31 and the driven block 32 are both located between the two guide blocks 4 and fit with the guide blocks 4. The two guide blocks 4 cooperate to limit the displacement of the active block 31 and the driven block 32 along the radial direction of the fixed rod 1. A guide groove 41 is provided on the side of the guide block 4 close to the active block 31. The guide groove 41 is arranged along the axis of the fixed rod 1 pointing to the direction of the water inlet 12. There are two groups of guide grooves 41 provided on the same guide block 4, and the two groups of guide grooves 41 are opposite and distributed in a mirror image. The active block 31 and the driven block 32 are both fixedly connected with a slider 33 adapted to the guide groove 41. The slider 33 is inserted into the guide groove 41 and is slidably connected to the guide block 4 along the length direction of the guide groove 41.

[0035] Reference Figure 5 and Figure 6 The guide groove 41 includes a straight portion 411 and an inclined portion 412. The straight portion 411 is perpendicular to the axis of the fixed rod 1. The inclined portion 412 is connected to the end of the straight portion 411 away from the water inlet 12 and is inclined in the direction away from the water inlet 12. For the two guide grooves 41 on the same guide block 4, their inclined portions 412 are away from each other along the direction of the water inlet 12 pointing to the axis of the fixed rod 1. In the initial state, the sliders 33 on the active block 31 and the driven block 32 are both located in the straight portion 411. At this time, the active block 31 and the driven block 32 are attached to each other and face the water inlet 12.

[0036] Reference Figure 1 and Figure 3 The fixed rod 1 is provided with a moving rod 13 for driving the active block 31 and the driven block 32 to move. Two moving rods 13 are provided. The two moving rods 13 are parallel to each other and are slidably connected to the fixed rod 1 along the axis direction of the fixed rod 1. The projection of the water inlet 12 on the horizontal plane is located between the two moving rods 13. The fixed rod 1 is provided with a hydraulic connection cylinder 14 for driving the two moving rods 13 to move. The hydraulic connection cylinder 14 is located at one end of the fixed rod 1 away from the top block 10. A piston rod 141 is slidably connected inside the hydraulic connection cylinder 14 along the axis direction. The piston rod 141 passes through the fixed rod 1 and is fixedly connected to the two moving rods 13.

[0037] Reference Figure 1 and Figure 3The hydraulic connection tube 14 is used to connect to an external hydraulic system. When installing the fixed rod 1, the operator connects to the external hydraulic system through the hydraulic connection tube 14, and then drives the piston rod 141 to move through the hydraulic system. When the piston rod 141 moves, it drives the two moving rods 13 to move synchronously. The application of the hydraulic system and the piston rod 141 is a common driving structure in the industrial field. It is a prior art and will not be described in detail here. A mounting plate 191 is vertically fixed to the end of the fixed rod 1 away from the top block 10. The mounting plate 191 is provided with a mounting hole, and the mounting plate 191 is provided with a fixing anchor rod 192 adapted to the mounting hole. When installing the fixed rod 1, the operator can pass the fixing anchor rod 192 through the mounting hole and insert it into the inner wall of the mine tunnel, thereby fixing the fixed rod 1.

[0038] Reference Figure 3 and Figure 5 The moving rod 13 is fixedly connected with a plurality of push blocks 131 corresponding to the active block 31 along the length direction, and the push block 131 is located on the side of the active block 31 away from the water inlet 12. A guide surface is arranged on the side of the push block 131 close to the active block 31, and the guide surface gradually tilts toward the water inlet 12 in the direction away from the top block 10, and the side of the active block 31 away from the water inlet 12 is in contact with the guide surface. When the moving rod 13 drives the push block 131 to approach the top rod 133, the push block 131 drives the active block 31 to extend out of the water inlet 12 through the guide surface, and when the active block 31 moves, it drives the driven block 32 to move synchronously.

[0039] Reference Figure 2 and Figure 3 The active block 31 and the driven block 32 are both provided with inclined surfaces on the side away from the moving rod 13, and the two inclined surfaces gradually approach each other along the direction of the moving rod 13 pointing to the active block 31. By setting the inclined surfaces, the active block 31 and the driven block 32 form a tip on the side away from the moving rod 13. When the fixed rod 1 is installed in the inner wall of the mine tunnel, the active block 31 and the driven block 32 extend from the water inlet 12 to squeeze and break the rock, so that the whole rock forms a crack corresponding to the water inlet 12.

[0040] Reference Figure 3 and Figure 4, the side of the active block 31 and the driven block 32 away from each other are both connected with the material box 5 along the radial sliding of the fixed rod 1, and the upper end of the material box 5 is in contact with the inner wall of the fixed rod 1, and a support block for limiting the material box 5 is fixed in the fixed rod 1, and the support block is in contact with the lower end of the material box 5, and the material box 5 is connected with the support block in the axial direction of the fixed rod 1. A feed port 51 is provided on the side of the material box 5 close to the corresponding active block 31 or the driven block 32. When the ends of the active block 31 and the driven block 32 with inclined surfaces are located in the water inlet 12, the feed port 51 is opposite to the inclined surface. When the active block 31 and the driven block 32 extend from the water inlet 12, the feed port 51 of the corresponding material box 5 is blocked. A spring 2 52 is fixed between the active block 31 and the material box 5, and the spring 2 52 is in a compressed state, and applies a thrust to the active block 31 away from the water inlet 12.

[0041] Reference Figure 3 and Figure 5 After the extrusion is completed, the moving rod 13 is operated to be recovered. A rotating rod 132 corresponding to the active block 31 is fixedly connected between the two moving rods 13. A hooking rod 313 is hinged on the side of the active block 31 away from the driven block 32. The rotating rod 132 is located on the side of the corresponding hooking rod 313 close to the top block 10. The hooking rod 313 is provided with a hooking port 314 facing the rotating rod 132. When the moving rod 13 drives the active block 31 to extend from the water inlet 12, the rotating rod 132 moves in a direction away from the hooking port 314.

[0042] Reference Figure 3 and Figure 6 When the moving rod 13 is reset, under the action of the spring 2 52 and gravity, the active block 31 and the driven block 32 are retracted into the water inlet 12. When the rotating rod 132 enters the hanging interface 314 and contacts the hanging rod 313, the moving rod 13 continues to move away from the top rod 133. At this time, the active block 31 and the driven block 32 both enter the fixed rod 1. The rotating rod 132 applies a pulling force to the active block 31 through the hanging rod 313, so that the active block 31 continues to move away from the water inlet 12. In this process, the slider 33 (reference Figure 5 ) enters the inclined portion 412 from the straight portion 411. Under the guidance of the inclined portion 412, the active block 31 and the driven block 32 move away from each other, so that the water inlet 12 is directly opposite to the bottom of the fixed rod 1. When water seepage occurs in the rock and soil on the inner wall of the mine tunnel, the seeping water enters the water inlet 12 along the gaps squeezed and crushed by the active block 31 and the driven block 32, and flows into the inside of the fixed rod 1 along the water inlet 12.

[0043] Reference Figure 1 and Figure 3A water seepage sensor 2 is arranged on the side of the fixed rod 1 away from the top block 10. The water seepage sensor 2 includes a probe 21, an alarm 22 and a sensor 23. The probe 21 is located inside the water collecting box 11. The sensor 23 is fixedly connected to the fixed rod 1, and the probe 21 is electrically connected to the sensor 23. After the seepage water enters the fixed rod 1, it gathers and accumulates in the water collecting box 11 under the action of gravity. When the accumulated water in the water collecting box 11 covers the probe 21, the probe 21 works and triggers the sensor 23.

[0044] Reference Figure 2 and Figure 3 , a drain port 111 communicating with the outside is opened at the lower end of the water collecting box 11, and a blocking block 181 is arranged inside the drain port 111, and the blocking block 181 is slidably connected to the water collecting box 11 along the radial direction of the fixed rod 1. The water collecting box 11 is also equipped with an opening and closing motor 182, and the opening and closing motor 182 is used to drive the blocking block 181 to move. In the initial state, the blocking block 181 is located in the drain port 111 and blocks the drain port 111. The opening and closing motor 182 is electrically connected to the sensor 23, and the sensor 23 has a triggering state on both sides. When the sensor 23 is triggered for the first time, the blocking block 181 is driven to move out of the drain port 111 by the opening and closing motor 182, and then the accumulated water in the water collecting box 11 is discharged, and then the opening and closing motor 182 drives the blocking block 181 to block the drain port 111 again.

[0045] Reference Figure 1 and Figure 3 , the alarm 22 is installed on one side of the sensor 23 and is electrically connected to the sensor 23. When water accumulates in the water collecting box 11 again and the sensor 23 is triggered for the second time, if the time of the second triggering of the sensor 23 is lower than the preset value, it means that the water accumulates at a fast speed and water seepage occurs in the mine tunnel. The sensor 23 controls the alarm 22 to sound an alarm. If the time of the second triggering of the sensor 23 is higher than the preset value, it means that the water accumulates in the water collecting box 11 at a slow speed. It is mainly condensed water or water accumulated by other factors. No warning is required, which is conducive to reducing the probability of false triggering of the sensor 23 and further improving the monitoring accuracy. During detection, external condensed water is not easy to penetrate into the inner layer of rock and soil, which reduces the interference of condensed water on the water seepage sensor 2. There is no need to frequently clean the condensed water, which improves the convenience of use and monitoring accuracy of the monitoring device.

[0046] Reference Figure 2 and Figure 4The fixed rod 1 is provided with water collection ports 15 on both sides along the horizontal direction. When the flow path of the seepage water in the rock wall of the mine tunnel is not directly opposite to the water inlet 12, if the seepage water falls on the outside of the fixed rod 1 under the action of gravity, it will flow toward the water collection port 15 along the outer surface of the fixed rod 1. The outer surface of the fixed rod 1 is provided with an avoidance groove 16 connected to the water collection port 15, and a plurality of arc plates 161 are arranged in the avoidance groove 16, and the outer diameter of the arc plate 161 is the same as the outer diameter of the fixed rod 1. All the arc plates 161 cooperate to support the fixed rod 1, preventing the inner wall of the avoidance groove 16 from directly contacting the rock and soil, so that the seepage water flows along the gap between adjacent arc plates 161, which is conducive to improving the monitoring range and the monitoring accuracy.

[0047] Reference Figure 2 and Figure 4 A plurality of guide blocks 171 are arranged in the water collection port 15. The plurality of guide blocks 171 are distributed along the length direction of the water collection port 15, and the upper end of the guide block 171 is fixedly connected to the inner wall of the water collection port 15. The diameter of the guide block 171 gradually decreases in the direction away from the water inlet 12. When the infiltrated water flows along the side wall of the water collection port 15, the guide block 171 is used to guide the infiltrated water to converge and accelerate the speed of the infiltrated water dripping. Two guide bars 172 are arranged between adjacent guide blocks 171. The two guide bars 172 are arranged opposite to each other, and the guide bars 172 gradually tilt from the direction close to the guide block 171 to the direction away from the water inlet 12. When the infiltrated water contacts the guide bar 172, it flows along the guide bar 172 to the guide block 171, further accelerating the speed of the infiltrated water convergence.

[0048] Reference Figure 2 and Figure 4 A sealing plate 6 adapted to the water collection port 15 is hinged inside the fixed rod 1, and a torsion spring 61 is provided between the sealing plate 6 and the fixed rod 1. When the torsion spring 61 is in the natural state, the sealing plate 6 is located in the water collection port 15 and blocks the water collection port 15, thereby reducing the probability of external rock and soil entering the fixed rod 1 when the fixed rod 1 is installed. A contact block 62 is fixedly provided on the side of the sealing plate 6 close to the axis of the fixed rod 1, and an arc surface is provided on the side of the contact block 62 close to the top block 10. The movable rod 13 is fixedly connected to a top rod 133 corresponding to the contact block 62, and the top rod 133 is located on the side of the corresponding contact block 62 close to the top block 10.

[0049] Reference Figure 2 and Figure 4 When the moving rod 13 moves away from the top block 10, the top rod 133 contacts the arc surface and pushes the contact block 62 to move toward the axis of the fixed rod 1 through the arc surface. When the contact block 62 moves, it drives the sealing plate 6 to move out of the water collection port 15, so that the water collection port 15 is connected with the internal cavity of the fixed rod 1. When the infiltrated water flows to the water collection port 15, it enters the fixed rod 1 from the water collection port 15 and gathers in the water collection box 11.

[0050] The working principle of a gold mine safety monitoring device in the embodiment of the present application is as follows: the fixed rod 1 is extended into the inner wall of the mine tunnel. When infiltration occurs, the infiltrated water is guided through the water inlet 12 or the water collection port 15 into the fixed rod 1, so that the infiltrated water is gathered in the water collection box 11. When the infiltration speed reaches the warning line, the sensor 23 is continuously triggered and an alarm is sounded through the alarm 22. During the monitoring process, the condensed water on the inner wall of the mine tunnel is difficult to pass through the rock and soil and enter the inner side of the fixed rod 1, reducing the interference of the condensed water. At the same time, by setting the alarm after the secondary trigger, external interference is further eliminated, and the convenience of use and monitoring accuracy of the monitoring device are improved.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
