Description

Technical Field

[0001] The present invention belongs to the technical field of gas outburst monitoring equipment, and relates to a real-time monitoring equipment and its components for preventing and controlling coal and gas outbursts in underground coal mines. Background Art

[0002] Coal and gas outburst is an extremely complex gas dynamic phenomenon in underground coal mines and one of the serious natural disasters underground. Under the interference of artificial mining activities, the original stress balance state in the coal seam is destroyed, the physical and mechanical properties of the coal (coal body strength) change from strong to weak, while the in-situ stress (including self-weight stress, tectonic stress, mining-induced stress) and gas pressure relatively increase; under the action of the in-situ stress, the original structure of the coal seam is damaged, a large number of secondary fractures are generated, and a large number of free surfaces are formed, resulting in the rapid and large-scale desorption of the adsorbed gas rich in the coal seam, which is transformed into free gas, forming a huge gas expansion pressure. When this energy accumulates to a certain extent, it drives the soft coal rich in a large number of secondary fractures to break through the coal body strength, and instantly ejects a large amount of gas (up to millions of cubic meters) and coal (up to ten thousand tons), causing a gas dynamic phenomenon underground. Generally, the deeper the coal mine is mined, the greater the energy released during coal and gas outburst.

[0003] For the existing real-time monitoring equipment for preventing and controlling coal and gas outbursts in mines, during use, air in the environment is usually sucked into the detection pipeline by a suction device, and a gas concentration sensor is used for monitoring. In addition, a microseismic signal data conduction rod is used to fit against the mine wall for vibration monitoring to comprehensively achieve the prevention and control monitoring of gas outburst disasters. However, when extracting underground environmental gas, first, the air components in different directions underground are different. The current single-way suction process only sucks the mixed air around the underground monitoring equipment into the detection. When the gas concentration is actually detected to be abnormal, the actual direction cannot be effectively judged. Moreover, the actually inhaled air is detected in the pipeline for a short time, and the environmental gas concentration will have an abnormal intermittent change of being sometimes high and sometimes low for a period of time before an actual gas outburst. The rapid and short-term detection cannot achieve rigorous and effective monitoring and prevention, and it is easy to make misjudgments, making it difficult to achieve the advanced prevention and control of coal and gas outbursts, and the actual use effect is not good.

[0004] In addition, for the real-time monitoring equipment for preventing and controlling coal and gas outbursts in the existing monitoring means, when fitting and fixing the microseismic signal data conduction rod against the inner wall of the mine, multiple groups of fixings are usually required to facilitate the real-time monitoring of multiple groups of inner wall surfaces of the mine. In order to avoid the loss of the microseismic signal data conduction rod with a long-distance transmission signal, a connecting rope is usually required for connection. However, after long-distance fixing, when collecting multiple groups of microseismic signal data conduction rods, they need to be collected one by one, and after collection, the connecting ropes need to be sorted out and stored. The actual operation is troublesome, and frequent running is required, and the use effect is not good. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the air flow entering the trachea is divided into two streams by using a connecting plate in the trachea, and by extending the length of the second pipe, the flow distance of the air flow in the second pipe is increased, so that the air flow in the first pipe undergoes two detections before and after, and the air flow in the second pipe is delayed for the third detection. The second gas sensor detects two different groups of air flows before and after, thereby realizing three detections of the same air flow and simultaneous detection of different air flows, improving the detection frequency of the same air flow, accurately obtaining the gas concentration in the air, and completing the control detection of different groups of air flows to judge the self-fault detection of the gas sensor. This greatly improves the monitoring effect of the surrounding gas-containing air flow during the prevention and control of coal and gas outbursts.

[0019] 2. In the present invention, the movement control of the control mechanism is realized by using the threaded rod in the operation adjustment mechanism. When the control mechanism moves downward, the side port is opened and the air hole is sealed at the same time. With the suction effect of the air pump, ambient air is inhaled through the fixed sleeve. Then, the air flow flowing through the fixed sleeve at high speed drives the blades in the winding mechanism to rotate, and drives the movable cylinder to rotate, thereby winding up the connecting rope, so that the micro-vibration monitoring mechanism at the outer end of the connecting rope is pulled back to the fixed sleeve, and at the same time, the rapid recovery of multiple groups of micro-vibration monitoring mechanisms is completed. The operation is simple and convenient to use, avoiding the workers running back and forth, and the use effect is good.

[0020] 3. In the present invention, during the operation process of recovering the micro-vibration monitoring mechanism, as the control mechanism is pushed downward, while the air hole is sealed, the dust outside the air hole is scraped off, and the dust and impurities falling on the fixed ring and accumulating slide into the annular groove. Then, the dust in the annular groove falls into the space between the fixed ring and the fixed circle. In cooperation with the discharge port opened on the outer surface of the fixed pipe below the fixed circle, the internal dust is conveniently cleaned. During the process of recovering the micro-vibration monitoring mechanism, the filtered dust and impurities are transferred to the discharge port, thus greatly improving the convenience of cleaning the filter, with actual cleaning being convenient and the operation being simple.

[0037] As Figures 1 to 9 shown, the embodiment of the present invention provides a real-time monitoring device for preventing coal and gas outbursts in underground coal mines, including a base 1, a first gas sensor 8, a second gas sensor 9, and a microseismic monitoring mechanism 19. A fixed pipe 2 is fixedly connected to the top surface of the base 1, and an adjusting mechanism 3 is fixedly communicated with the top surface of the fixed pipe 2. An air pipe 4 is fixedly communicated with the side surface of the adjusting mechanism 3. A connecting plate 5 is fixedly sleeved on the inner surface of the air pipe 4. A first pipe 6 and a second pipe 7 are respectively fixedly communicated with the side surface of the connecting plate 5. The first gas sensor 8 is fixedly sleeved on the air pipe 4, and the lower end of the first gas sensor 8 passes through the first pipe 6 and extends into the interior of the first pipe 6. The second gas sensor 9 is fixedly sleeved on the outer surface of the air pipe 4, and the second gas sensor 9 is located on the side of the first pipe 6 and the second pipe 7. The number of the air pipes 4 is eight, and the eight air pipes 4 are annularly and equally spaced on the outside of the adjusting mechanism 3. The second pipe 7 is a curved pipe. A control box 12 and an air pump 10 are respectively fixedly installed on the top surface of the base 1. An air suction pipe 11 is fixedly communicated between the air pump 10 and the fixed pipe 2. A spring 14 located inside the fixed pipe 2 is fixedly connected to the top surface of the base 1. The upper end of the spring 14 is fixedly connected to a control mechanism 13. A fixed sleeve 16 is fixedly communicated with the side surface of the fixed pipe 2. A winding mechanism 17 is arranged inside the fixed sleeve 16.

[0038] The first embodiment: As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when gas concentration monitoring is required, the air pump 10 is started, so that the air pump 10 sucks air from the fixed pipe 2 through the suction pipe 11, and the control mechanism 13 is kept at the top inside the fixed pipe 2. As air is continuously sucked, the ambient air is divided into eight groups and respectively inhaled into the trachea 4, and the air flow in each trachea 4 is equally divided into two air flows via the communication plate 5. The two air flows respectively flow back into the trachea 4 via the first pipe 6 and the second pipe 7. As air is inhaled and flows along the first pipe 6 and the second pipe 7, the air A at the communication plate 5 is divided into two air flows a. The air flow a in the first pipe 6 comes into contact with the first gas sensor 8 for detection, and is secondarily detected when flowing to the second gas sensor 9. Subsequently, the air flow a in the second pipe 7 is delayed to flow to the second gas sensor 9 for a third detection. At the same time, the second gas sensor 9 completes the detection of the air flow b in the first pipe 6, and the data is processed by the processor in the control box 12 to obtain accurate gas information in the air. And when abnormal gas concentration is detected in a certain trachea 4, the control box 12 locates the abnormal gas sensor through the internal processor to obtain the trachea 4 with the specific abnormal orientation.

[0039] First, by using the communication plate 5 in the trachea 4 to divide the air flow entering the trachea 4 into two, and by extending the length of the second pipe 7 to increase the flow distance of the air flow in the second pipe 7, the air flow in the first pipe 6 is subjected to two detections before and after, and the air flow in the second pipe 7 is delayed for a third detection. The second gas sensor 9 detects two different air flow groups before and after, so as to realize three detections of the same air flow and simultaneous detection of different air flows, improve the detection frequency of the same air flow, accurately obtain the gas concentration in the air, and complete the control detection of different air flow groups to judge the self-fault detection of the gas sensor, greatly improving the monitoring effect of the surrounding gas-containing air flow in the process of preventing and controlling coal and gas outbursts. And in cooperation with the eight groups of tracheas 4 distributed in a ring, the actual abnormal orientation can be judged in time when abnormal gas concentration occurs, improving the prevention and control effect.

[0040] Among them, the adjusting mechanism 3 includes a distribution sleeve 31, a first hole 32, a second hole 33, an adjusting rod 34, a threaded pipe 35 and a threaded rod 36. The distribution sleeve 31 is fixedly connected to the top surface of the fixed pipe 2, the trachea 4 is fixedly connected to the outer surface of the distribution sleeve 31, the first hole 32 and the second hole 33 are respectively opened on the side surface and the top surface of the distribution sleeve 31, the first hole 32 and the second hole 33 are communicated with each other, the adjusting rod 34 is threadedly sleeved in the inner surface of the second hole 33, the threaded pipe 35 is fixedly communicated with the top surface of the distribution sleeve 31, the threaded rod 36 is threadedly sleeved inside the threaded pipe 35. By rotating the adjusting rod 34, the on-off of the first hole 32 and the second hole 33 can be controlled, and according to the actual detection requirements, the direction of sucking air for monitoring can be reduced, and the actual monitoring control freedom is high.

[0041] Among them, a discharge port 23 is formed on the outer surface of the fixed pipe 2. A fixing ring 22 is fixedly sleeved on the inner surface of the fixed pipe 2. An inclined surface is provided on the top surface of the fixing ring 22. The fixing ring 22 is located above the discharge port 23.

[0042] Among them, a connecting block 20 is fixedly connected to the inner surface of the fixed pipe 2. A sealing ring 21 is fixedly connected to the end face of the connecting block 20. The sealing ring 21 is located above the fixing ring 22. When it is necessary to seal the air hole 137, the sealing ring 21 is used to achieve stable sealing. The inner diameter of the sealing ring 21 is the same as that of the fixing ring 22, and both are slightly larger than the diameter of the control sleeve 135, ensuring full sealing while ensuring that the control sleeve 135 can slide up and down.

[0043] Among them, the control mechanism 13 includes a fixing rod 131, a top plate 132, a bottom rod 133, a bottom ring 134, a control sleeve 135, a fixing ring 136, an air hole 137 and a ring groove 138. The top plate 132 and the bottom rod 133 are respectively fixedly connected to the upper and lower surfaces of the fixing rod 131. The bottom ring 134 is fixedly connected to the bottom surface of the bottom rod 133. The control sleeve 135 is fixedly connected to the bottom surface of the top plate 132. The air hole 137 and the ring groove 138 are formed in the outer surface of the control sleeve 135 from top to bottom. The fixing ring 136 is fixedly connected to the bottom surface of the control sleeve 135. By using the up and down movement of the control mechanism 13, the control of the air suction direction in the fixed pipe 2 is realized, and the function switching of the gas monitoring and micro-vibration monitoring mechanism 19 for recovery is realized.

[0044] Among them, the fixing ring 136 is located below the fixing ring 22. The control sleeve 135 is movably sleeved inside the fixing ring 22 and the sealing ring 21. The width of the ring groove 138 is greater than the thickness of the fixing ring 22. The ring groove 138 is located above the fixing ring 22. The air hole 137 is located above the sealing ring 21. By controlling the position of the air hole 137 and the position and width of the ring groove 138, after moving down, the ring groove 138 leads out the dust on the fixing ring 22, and at the same time, the sealing ring 21 is used to seal the air hole 137, ensuring that only air is sucked from the side port 15 in the fixed pipe 2 at this time, and guiding the dust and impurities to the vicinity of the discharge port 23 for convenient cleaning.

[0045] Among them, a side port 15 is formed on the outer surface of the fixed pipe 2. A guiding sleeve 24 is fixedly connected to the inner surface of the fixed sleeve 16. The inner end of the guiding sleeve 24 is fixedly communicated with the side port 15. By using the guiding sleeve 24 to control the suction direction, air is sucked from the bottom, thereby realizing the bottom pushing of the winding mechanism 17 and realizing rotation.

[0046] Among them, a connecting rope 18 is wound inside the winding mechanism 17. The end face of the connecting rope 18 is fixedly connected to the microseismic monitoring mechanism 19. The microseismic monitoring mechanism 19 includes a microseismic signal data conduction rod 191 and an insertion rod 192. One side surface of the microseismic signal data conduction rod 191 is fixedly connected to the connecting rope 18. The insertion rod 192 is fixedly connected to the other side surface of the microseismic signal data conduction rod 191. The microseismic signal data conduction rod 191 in the microseismic monitoring mechanism 19 is attached to the coal and rock mass wall surface. Through vibration detection, it effectively monitors the prevention and control of coal and gas outbursts on the inner wall of the mine.

[0047] Among them, the winding mechanism 17 includes a movable cylinder 171, a movable shaft 172, blades 173, a socket groove 174, and a winding sleeve 175. The movable shaft 172 is movably sleeved inside the fixed sleeve 16. The movable cylinder 171 is fixedly sleeved on the outer surface of the movable shaft 172. The socket groove 174 is opened on the outer surface of the movable cylinder 171. The blades 173 are fixedly connected to the outer surface of the movable cylinder 171 and are located on both sides of the socket groove 174. The winding sleeve 175 is fixedly sleeved on the inner surface of the socket groove 174. By sucking ambient air from below the winding mechanism 17 into the guiding sleeve 24, the blades 173 of the winding mechanism 17 are pushed from below, thereby driving the rotation of the winding mechanism 17, realizing the winding of the connecting rope 18, and further realizing the automatic retraction of the microseismic monitoring mechanism 19.

[0048] Among them, a connecting plate 25 is fixedly connected to the inner surface of the fixed sleeve 16. The end face of the connecting plate 25 is fixedly connected to a sleeve 26. The inner surface of the sleeve 26 is movably sleeved with the connecting rope 18. By using the sleeve 26 to sleeve the connecting rope 18, the retracted microseismic monitoring mechanism 19 has a limiting effect during retraction, avoiding the microseismic monitoring mechanism 19 from completely moving into the fixed sleeve 16, and improving the convenience of next taking.

[0049] Second Embodiment: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and 9As shown, when recovering the microseismic monitoring mechanism 19, the threaded rod 36 in the rotation adjustment mechanism 3 moves downward along the threaded tube 35, pushing the control mechanism 13 downward and compressing the spring 14. When the bottom ring 134 in the control mechanism 13 moves below the side port 15, at the same time, the top plate 132 moves below the adjustment mechanism 3, and the air hole 137 moves to the inner side of the sealing ring 21. At this time, the air in the fixed tube 2 is not connected to the adjustment mechanism 3, the air suction in the air pipe 4 stops, and at the same time, the fixed tube 2 pumps air into the side port 15. As the ambient air is inhaled through the fixed sleeve 16 and flows into the guide sleeve 24, the air flowing in the fixed sleeve 16 pushes the blades 173 in the winding mechanism 17 to rotate, so that the winding mechanism 17 rotates. As the winding mechanism 17 rotates, the connecting rope 18 is gradually wound around the socket groove 174 of the winding mechanism 17. The connecting rope 18 pulls the microseismic monitoring mechanism 19 to move and recover to the end face of the fixed sleeve 16 and contact the sleeve 26, completing the recovery and fixation of multiple groups of microseismic monitoring mechanisms 19. Then the air pump 10 can be closed.

[0050] First, by using the threaded rod 36 in the operation adjustment mechanism 3 to control the movement of the control mechanism 13, when the control mechanism 13 moves downward, the side port 15 is opened, and at the same time, the air hole 137 is sealed. With the suction effect of the air pump 10, the ambient air is inhaled through the fixed sleeve 16. Then, the high-speed flowing air in the fixed sleeve 16 is used to push the blades 173 in the winding mechanism 17 to rotate, driving the movable cylinder 171 to rotate, thereby winding up the connecting rope 18, pulling the microseismic monitoring mechanism 19 at the outer end of the connecting rope 18 to be recovered to the fixed sleeve 16, and at the same time, quickly recovering multiple groups of microseismic monitoring mechanisms 19. The operation is simple and convenient to use, avoiding the worker running back and forth, and the use effect is good.

[0051] Third Embodiment: As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 shown, when continuous air monitoring is carried out, the dust in the continuously inhaled air enters the adjustment mechanism 3 through the air pipe 4, is filtered outside the control sleeve 135 of the control mechanism 13, and gradually accumulates on the top surface of the fixed ring 22. When the gas monitoring stops and the microseismic monitoring mechanism 19 is recovered, as the threaded rod 36 pushes the control mechanism 13 downward, when the air hole 137 moves to the inside of the sealing ring 21, at this time, the annular groove 138 moves to one side of the fixed ring 22, so that the dust and impurities on the top of the fixed ring 22 slide down along the inclined plane into the annular groove 138, and fall through the annular groove 138 into the space between the fixed ring 136 and the fixed ring 22, and the falling dust and impurities are on one side of the discharge port 23. The dust and impurities can be cleaned through the discharge port 23.

[0052] First, by utilizing the operation process of the recycling microseismic monitoring mechanism 19, while achieving the sealing of the air hole 137 as the driving control mechanism 13 moves downward, the dust outside the air hole 137 is scraped off, and the dust and impurities that fall on and accumulate on the fixed ring 22 slide into the annular groove 138, and then the dust in the annular groove 138 falls into the space between the fixed ring 136 and the fixed ring 22. In cooperation with the discharge port 23 opened on the outer surface of the fixed pipe 2 and located below the fixed ring 22, the internal dust is conveniently cleaned. During the process of the recycling microseismic monitoring mechanism 19, the filtered dust and impurities are transferred to the discharge port 23, thereby greatly improving the convenience of cleaning the filter, with actual cleaning being convenient and the operation being simple.
