Description

Technical Field

[0001] This invention relates to the field of gas control, and more specifically, to a gas control system, apparatus and method for mines. Background Technology

[0002] Before coal mining, coal seam gas needs to be extracted. During the extraction process, an organic matter measuring instrument is used to detect the gas concentration and reduce it to below a safe level to prevent gas explosions and accidents. However, the current gas detection process is prone to abnormal and invalid data. When the invalid value is higher than the safe gas level, the alarm system is triggered and an alarm is issued. At this time, it does not mean that the gas concentration inside the mine is too high, which causes inconvenience to the staff.

[0003] For example, the Chinese invention patent (application number: 202211072691.7) discloses a "Real-time Monitoring Device and Components for Coal and Gas Outburst Prevention in Coal Mines," whose specification states that it includes a base, a first gas sensor, a second gas sensor, and a micro-vibration monitoring mechanism. A fixed pipe is fixedly connected to the top surface of the base. This invention achieves three detections of the same airflow and simultaneous detection of different airflows by delaying the airflow in the second pipe and detecting two different airflow groups before and after the second gas sensor. This increases the detection frequency of the same airflow, accurately obtains the gas concentration in the air, and completes comparative detection of different airflow groups to determine the fault detection of the gas sensor itself. This greatly improves the monitoring effect of underground airflow during coal and gas outburst prevention. Furthermore, with eight sets of gas pipes arranged in a ring, the actual location of the abnormal gas concentration can be determined in a timely manner, improving the prevention effect. The aforementioned patent can corroborate the deficiencies of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a mine gas control system, device and method. Summary of the Invention

[0025] A method for preventing and controlling gas in mines includes the following steps:

[0026] S1. Initial drilling: Water is delivered to the water turbine, which drives the drilling structure to crush and cut the coal mine. At the same time, it propels the outer shell to move towards the mining face. When the coal seam is soft, the cutting method is used. When the coal seam is hard, the crushing and cutting method is used first.

[0027] S2. After the hole is deepened and the moving structure is submerged in the drilled channel, an extension pipe is installed. Water is then supplied to the inside of the water turbine through the extension pipe to drive the drilling structure to continue drilling.

[0028] S3. Propulsion: The moving structure drives the drilling structure, percussion structure, and transmission structure to move into the channel;

[0029] S4. Retract, stop supplying water to the inside of the moving structure, the moving structure separates from the inner wall of the channel, and pull the extension pipe to pull out the moving structure and the transmission structure;

[0030] S5. Evacuate air, remove the extension tube, and move the outer casing to insert the sealing cover into the channel;

[0031] S6. Exhaust gas, which discharges the extracted gas to the outside of the mine.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] In the scheme of this application:

[0034] 1. In order to solve the problem that abnormal and invalid data are easily generated during the gas detection process in the existing technology, triggering the alarm system and causing inconvenience to the staff, this application realizes the automatic analysis of abnormal data and transmits information through two alarm sounds by setting up a gas prevention and control system in the mine;

[0035] 2. In order to solve the problem that the drilling efficiency is low when the same drilling method is used for coal seams with different softness in the prior art, this application realizes the processing of coal seams by combining the drilling structure and the hammering structure. When the coal seam is soft, the cutting method is used, and when the coal seam is hard, the crushing and then cutting method is used.

[0036] 3. By using the transmission structure and the limiting structure in combination, the operation of the drilling structure can be controlled by moving the position of the transmission structure;

[0037] 4. By setting up a movable structure, the drilling structure can move inside the channel, which solves the problem in the prior art that the drilling structure needs to be driven to move outside the channel. Attached Figure Description

[0053] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0054] As described in the background section, abnormal and invalid data can easily occur during gas detection, triggering the alarm system and causing inconvenience to staff.

[0055] To address this technical problem, the present invention provides a mine gas control system, device, and method, which are applied to gas detection.

[0056] For details, please refer to Figure 1 The specific components of a mine gas control system include:

[0057] The controller controls the infrared emitting module to emit infrared light;

[0058] Multiple infrared emitting modules alternately emit infrared light;

[0059] Multiple infrared receiving modules receive infrared light emitted by corresponding infrared emitting modules and convert it into electrical signals based on the intensity of the infrared light, which are then transmitted to the processor.

[0060] The processor analyzes the infrared data received by the infrared receiving module to obtain the gas concentration value;

[0061] The recorder records the data analyzed by the processor in real time.

[0062] The display shows the gas concentration value in real time. When the alarm sounds, the inspectors use the data displayed on the display to determine whether the data exceeding the safe value is accurate.

[0063] The alarm sounds when the gas concentration value obtained by the processor exceeds the safe value.

[0064] The input module allows users to input a safety command to stop the alarm from sounding when the value triggering the alarm is inaccurate.

[0065] The beneficial effects of the mine gas control device provided by this invention.

[0066] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0067] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0069] Example 1

[0070] Please refer to Figure 1 A mine gas control system, comprising

[0071] The controller controls the infrared emitting module to emit infrared light;

[0072] Multiple infrared emitting modules alternately emit infrared light;

[0073] Multiple infrared receiving modules receive infrared light emitted by corresponding infrared emitting modules and convert it into electrical signals based on the intensity of the infrared light, which are then transmitted to the processor.

[0074] The processor analyzes the infrared data received by the infrared receiving module to obtain the gas concentration value. When the gas concentration value exceeds the safe value, it compares it with the previous and subsequent data and triggers the alarm.

[0075] The recorder records the data analyzed by the processor in real time.

[0076] The monitor displays the gas concentration value in real time. When the alarm sounds with a slow rhythm, the inspectors use the data displayed on the monitor to determine whether the data exceeding the safe value is accurate.

[0077] The alarm includes multiple alarm sounds. When the gas concentration value obtained by the processor is greater than the safe value, an alarm is sounded. When the gas concentration value exceeds the safe value and differs significantly from the previous and subsequent data, the alarm sounds with a slower rhythm. When the gas concentration value exceeds the safe value and differs slightly from the previous and subsequent data, the alarm sounds with a faster rhythm.

[0078] The input module allows users to input a safety command to stop the alarm from sounding when the value triggering the alarm is inaccurate.

[0079] When the gas concentration exceeds the safe value, the system can automatically analyze whether the value is abnormal, preventing staff from panicking when data is abnormal and reducing unnecessary trouble.

[0080] Example 2

[0081] The mine gas control device provided in Example 1 has been further optimized, specifically, as follows: Figure 2 and Figure 10 As shown, a mine gas control device includes a shell 1, an infrared emitting module and an infrared receiving module, both mounted on the shell 1. A rigid pipe 2 is provided on one side of the shell 1. A movable structure 3 is provided outside the rigid pipe 2. A limiting structure 8 is provided at the end of the rigid pipe 2. A transmission structure 7 is provided outside the limiting structure 8. A drilling structure 5 is provided on the side of the transmission structure 7 away from the rigid pipe 2. A striking structure 6 is provided between the drilling structure 5 and the limiting structure 8. The drilling structure 5 drills a hole inside the mine to create a channel. The transmission structure 7 drives the drilling structure 5 to rotate or drives the striking structure 6 to strike the drilling structure 5, causing the drilling structure 5 to break the ore. The movable structure 3 drives the limiting structure 8 and the drilling structure 5 to move within the channel, achieving more efficient drilling by using two methods to assist each other.

[0082] Two drilling methods are designed for coal seams of varying hardness to improve drilling efficiency.

[0083] Furthermore, such as Figure 3As shown, the interior of the outer shell 1 is provided with a first partition 12. On both sides of the first partition 12 are a filter screen 14 and a second partition 13, respectively. The filter screen 14 is located on the side of the first partition 12 near the rigid pipe 2. A water pump 15 and an air pump 9 are provided below the second partition 13. The water outlet pipe of the water pump 15 and the air outlet pipe of the air pump 9 both extend to the top of the second partition 13. The water inlet pipe of the water pump 15 passes through the extension of the first partition 12 to the bottom of the filter screen 14. The end of the rigid pipe 2 is connected to the water outlet pipe of the water pump 15 through an extension pipe. The air outlet pipe of the air pump 9 passes through the outer shell 1 and extends to the outside of the outer shell 1. The water pump 15 pumps water to the rigid pipe 2, and the air pump 9 extracts the gas inside the outer shell 1. A vent hole is opened on the first partition 12 located below the filter screen 14. After the air pump 9 draws the gas into the interior of the outer shell 1, it passes through the filter screen 14 to filter the coal powder in the gas. Then the gas is discharged to the outside of the mine for storage through a pipeline.

[0084] During drilling, water pump 15 supplies water into the channel, and the water drives the drilling structure 5 and the striking structure 6 to operate, while avoiding the high temperature generated during drilling from igniting gas.

[0085] Furthermore, such as Figure 4 As shown, the moving structure 3 includes a control structure 31 sleeved on the outside of the rigid tube 2. Two annular tubes 32 are sleeved on the outside of the control structure 31. Three to five support structures 33 are provided along the circumference of each annular tube 32. A support plate 34 is provided on the side of each support structure 33 away from the control structure 31. A moving rod 35 is provided between two corresponding support structures 33 on the two annular tubes 32. The control structure 31 controls the extension and retraction of the two support structures 33 and the moving rod 35. During forward movement, the support structure 33 on the annular tube 32 away from the outer shell 1 extends, causing the support structure 33 to extend... The support plate 34 abuts against the channel wall, and the support structure 33 and the moving rod 35 on the other annular tube 32 shorten, causing the support structure 33 on the annular tube 32 near the outer shell 1 to move away from the outer shell 1. When the moving rod 35 is shortened to the position, the shortened support structure 33 on the annular tube 32 away from the outer shell 1 does not apply pressure to the channel wall. The support structure 33 on the other annular tube 32 extends and abuts against the channel wall. The moving rod 35 extends and pushes the support structure 33 on the annular tube 32 away from the outer shell 1, thereby realizing the movement of the moving structure 3 inside the channel.

[0086] The movable structure 3 moves inside the channel, thereby driving the drilling structure 5 towards the coal mine.

[0087] Furthermore, such as Figure 4 and Figure 9As shown, the control structure 31 includes a primary sealing sleeve 311 fixedly sleeved on the rigid pipe 2. A secondary sealing sleeve 312, also sleeved on the rigid pipe 2, is slidably disposed inside the primary sealing sleeve 311. Two sets of water delivery channels are provided on the circumferential side of the secondary sealing sleeve 312, each set including several strip-shaped holes 313. An inlet hose 314 is connected to the secondary sealing sleeve 312, extending into the interior of the outer casing 1. A connecting rod 317 is fixedly disposed at the end of the secondary sealing sleeve 312 away from the outer casing 1. A push plate 316 is fixedly connected to the end of the connecting rod 317 through the primary sealing sleeve 311. A first telescopic rod 315 is provided between the push plate 316 and the adjacent annular pipe 32. The two ends of the first telescopic rod 315 are respectively... Fixedly connected to push plate 316 and annular tube 32, primary sealing sleeve 311 communicates with annular tube 32 at the end away from outer shell 1. A connecting hose 318 located between the two annular tubes 32 is provided outside primary sealing sleeve 311. The connecting hose 318 communicates with annular tube 32 on the side closer to outer shell 1. Primary sealing sleeve 311 is connected to another outlet pipe of water pump 15. Water pump 15 inputs water into secondary sealing sleeve 312. Two return water ports are respectively located at both ends inside primary sealing sleeve 311 on the outside of rigid pipe 2. First telescopic rod 315 drives push plate 316 to move, push plate 316 drives connecting rod 317 to move, connecting rod 317 drives secondary sealing sleeve 312 to move, and secondary sealing sleeve 312... When moving towards the outer casing 1, the strip-shaped hole 313 communicates with the connecting hose 318. The connection between the annular tube 32 and the primary sealing sleeve 311 on the side away from the outer casing 1 is blocked by the secondary sealing sleeve 312. Water inside the secondary sealing sleeve 312 enters the annular tube 32 near the outer casing 1 through the strip-shaped hole 313 and the connecting hose 318. Water inside the annular tube 32 enters the adjacent first outer sleeve 331, pushing the infusion channel 332. The infusion channel 332 causes the inner sliding rod 335 to move away from the rigid tube 2. The support plate 34 near the outer casing 1 abuts against the inner wall of the channel. The strip-shaped hole 313 continues to move towards the outer casing 1. The strip-shaped hole 313 and the connecting hose 318 remain connected. The annular tube 32 and the primary sealing sleeve 311 on the side away from the outer casing 1 are blocked by the secondary sealing sleeve 312. The connection between 11 is no longer blocked, and water enters the first-stage sealing sleeve 311 from the annular tube 32, and then enters the rigid tube 2 from the first-stage sealing sleeve 311. At this time, the first return spring 336, away from the outer shell 1, pushes the first piston disc 334 to move the inner slide rod 335 closer to the rigid tube 2. Water inside the second-stage sealing sleeve 312 continues to flow into the connecting hose 318. After the first piston disc 334 passes through the infusion channel 332, water inside the first outer sleeve 331 enters the second outer sleeve 351, causing the moving rod 35 to extend and push the annular tube 32 away from the outer shell 1 to move. Then, the second-stage sealing sleeve 312 moves away from the outer shell 1, and the strip hole 313 away from the outer shell 1 connects with the annular tube 32 away from the outer shell 1.The secondary sealing sleeve 312 blocks the connection between the connecting hose 318 and the primary sealing sleeve 311. Water inside the support structure 33 near the outer shell 1 cannot enter the primary sealing sleeve 311. Water inside the secondary sealing sleeve 312 enters the annular pipe 32 away from the outer shell 1. The piston disc 334 on the side away from the outer shell 1 is pushed by gas, causing the support plate 34 on that side to abut against the inner wall of the channel. The secondary sealing sleeve 312 continues to move away from the outer shell 1, and the connecting hose 318 connects with the interior of the primary sealing sleeve 311. One side's return spring 336 pushes the first piston disc 334 on that side, causing water inside the first outer sleeve 331 to drain into the first-stage sealing sleeve 311. The support plate 34 on that side no longer abuts against the inner wall of the channel. When the first piston disc 334 passes through the infusion channel 332, the second return spring 354 pushes the second piston disc 352, causing water inside the second piston disc 352 to drain through the second outer sleeve 351 from the drain port 333. Therefore, the moving rod 35 shortens. Repeating the above steps allows the moving structure 3 to move within the channel.

[0088] The system controls the injection of water into the two annular pipes 32, thereby controlling the extension and retraction of the two support structures 33 and the movable rods 35.

[0089] Furthermore, such as Figure 9 As shown, the support structure 33 includes a first outer tube 331 connected to the annular tube 32. A first piston disc 334 is slidably disposed inside the first outer tube 331. An inner slide rod 335 is fixedly disposed on the side of the first piston disc 334 away from the control structure 31. A first return spring 336 is sleeved on the inner slide rod 335. The end of the inner slide rod 335 passes through the first outer tube 331 and is fixedly connected to the support plate 34. A drain port 333 is opened on the first outer tube 331 near the outer shell 1, and the position of the drain port 333 is close to the outer shell 1. An infusion channel 332 is opened on the other side of the first outer tube 331.

[0090] The infusion channel 332 allows water to be injected into the moving rod 35, and the drain port 333 allows water to be discharged from the moving rod 35. The first piston disc 334 drives the inner slide rod 335 to move, thereby extending and retracting the support structure 33. The elastic force of the first return spring 336 allows water to be discharged when the external water pressure of the first outer sleeve 331 decreases.

[0091] Furthermore, such as Figure 9 As shown, the movable rod 35 includes a second outer sleeve 351 that communicates with the infusion channel 332. A second piston disc 352 is slidably disposed inside the second outer sleeve 351. A push rod 353 is fixedly disposed on the side of the second piston disc 352 away from the first outer sleeve 331. A second return spring 354 located inside the second outer sleeve 351 is sleeved on the push rod 353. The end of the push rod 353 is fixedly connected to the first outer sleeve 331 on the side away from the outer casing 1.

[0092] The telescopic movement of the movable rod 35 changes the distance between the two support structures 33, thereby driving the support structure 33 to move.

[0094] The mine gas control device provided in Example 2 has been further optimized, specifically, as follows: Figure 10 and Figure 12 As shown, further, the limiting structure 8 includes a limiting component fixedly connected to the end of the rigid pipe 2 away from the outer shell 1. The limiting component contains a driving component. The limiting component includes an isolation cover 81. An inner extension cylinder 83 is fixedly provided on the side of the isolation cover 81 away from the outer shell 1. A second external toothed ring 810 is fixedly provided on the circumferential side of the inner extension cylinder 83. The isolation cover 81 is fixedly connected to the rigid pipe 2 and also fixedly connected to an annular pipe 32 on the side away from the outer shell 1. The second sealing ring 82, the second external toothed ring 810, and the second telescopic rod 84 remain stable and do not rotate. A water turbine 11 located at the end of the rigid pipe 2 is provided inside the isolation cover 81. The driving component includes a transmission pipe 85 located on the output shaft of the water turbine 11. The transmission pipe 85 passes through the isolation cover 81 and is located inside the isolation cover 81. One end of the transmission pipe 85 is connected to the isolation cover cylinder 81. A primary gear 86 and a secondary gear 87 are fixedly sleeved on the outside of the transmission pipe 85. The secondary gear 87 is located between the primary gear 86 and the inner extension cylinder 83. Several second telescopic rods 84 are provided between the transmission pipe 85 and the inner extension cylinder 83. One end of the second telescopic rod 84 is fixedly connected to the isolation cover cylinder 81. A first external gear ring 88 is fixedly provided on the circumferential side of the transmission pipe 85 away from the isolation cover cylinder 81. A compensation pipe 89 is fixedly provided on the end of the transmission pipe 85 away from the isolation cover cylinder 81. A third sealing ring 811 is fixedly provided on the circumferential side of the compensation pipe 89. After the hard pipe 2 is input into the water turbine 11, the water turbine 11 drives the transmission pipe 85 to rotate. The water discharged from the water turbine 11 enters the transmission pipe 85. The transmission pipe 85 drives the primary gear 86, the secondary gear 87 and the first external gear ring 88 to rotate.

[0095] Limiting structure 8 drives transmission structure 7 to rotate or drive striking structure 6 to run.

[0096] Furthermore, such as Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the drilling structure 5 includes an outer support ring 51, inside which is an inner support ring 52. The outer support ring 51 and the inner support ring 52 are fixedly connected. Several impact plates 54 are provided on the circumferential side of the outer support ring 51 away from the outer shell 1. Two connecting seats 53 are provided between the impact plates 54 and the outer support ring 51. The two connecting seats 53 are fixedly connected to the outer support ring 51 and the inner support ring 52 respectively. An elongated moving hole 56 is opened on the upper part of the connecting seat 53. Both sides of the impact plate 54 are fixedly provided with objects located in the elongated moving hole 56. The movable rod 57 slides inside the elongated moving hole 56. The impact plate 54 has a spring groove on the side near the connecting seat 53. A compression spring 58 is installed inside the spring groove. The compression spring 58 keeps the impact plate 54 away from the connecting seat 53, which facilitates the rotation between the impact plate 54 and the connecting seat 53. A hydraulic rod 55 is hinged to one side of the impact plate 54. The other end of the hydraulic rod 55 is hinged to the outer support ring 51 through a hinge seat. The extension and retraction of the hydraulic rod 55 causes the impact plate 54 to rotate, changing the angle between the impact plate 54 and the coal seam.

[0097] When the impact plate 54 is perpendicular to the mining face, it strikes the coal to crush the ore. When the impact plate 54 is at an angle to the mining face, the drilling structure 5 rotates to cut the ore.

[0098] Furthermore, such as Figure 10-11As shown, the transmission structure 7 includes a protective cylinder 71 sleeved outside the isolation cover cylinder 81. A second sealing ring 82 and a first sealing ring 79 are provided between the isolation cover cylinder 81 and the protective cylinder 71. The second sealing ring 82 is fixedly sleeved outside the isolation cover cylinder 81, and the first sealing ring 79 is fixedly connected to the inner wall of the protective cylinder 71. The second sealing ring 82 is located on the side of the first sealing ring 79 away from the outer shell 1. The transmission structure 7 also includes a transmission cylinder 77 fixedly connected to the inner support ring 52 on the side near the outer shell 1. The transmission cylinder 77 has a fixed internal structure... There are three internal toothed rings 78. An annular plate 72 is fixedly installed in the middle of the protective cylinder 71. An outer extension cylinder 73 is fixedly installed on the side of the annular plate 72 near the outer support ring 51. An internal toothed ring 74 is installed on the inner side of the annular plate 72. An internal toothed ring 76 is installed on the inner side of the outer extension cylinder 73. A connecting ring 75 is fixedly installed inside the outer extension cylinder 73 between the internal toothed ring 76 and the internal toothed ring 74. The connecting ring 75 is fixedly connected to the other end of the second telescopic rod 84. When crushing ore, the second outer toothed ring 78 and the first inner toothed ring 74 are connected. 4. The meshing restricts the rotation of the annular plate 72. The first-stage gear 86 meshes with the second-stage gear 612. The rotation of the first-stage gear 86 drives the rotation of the second-stage gear 612, thereby driving the operation of the striking structure 6. At this time, the impact plate 54 is in a perpendicular state to the coal mine. When cutting the ore, the second telescopic rod 84 shortens and pulls the connecting ring 75 away from the isolation cover 81. The distance between the second sealing ring 82 and the first sealing ring 79 increases. The side of the first sealing ring 79 away from the second sealing ring 82 is connected to a liquid infusion pipe 10. The end of the liquid infusion pipe 10 Connected to the hydraulic rod 55, water inside the hydraulic rod 55 is pumped into the space between the first sealing ring 79 and the second sealing ring 82. The hydraulic rod 55 shortens, the impact plate 54 rotates and tilts to form an angle with the mining face, the first internal gear ring 74 and the second external gear ring 810 separate, the auxiliary gear 87 and the second internal gear ring 76 mesh, and the first external gear ring 88 and the third internal gear ring 78 mesh. When the transmission pipe 85 rotates, it drives the drilling structure 5 and the transmission structure 7 to rotate synchronously through the auxiliary gear 87 and the first external gear ring 88, respectively, and uses the hydraulic rod 55 to cut the coal mine.

[0099] The rotation of the transmission structure 7 drives the rotation of the drilling structure 5 to cut the ore.

[0100] Furthermore, such as Figure 4-7As shown, the striking structure 6 includes an inner fixing frame 61. The inner fixing frame 61 is fixedly connected to both the outer support ring 51 and the inner support ring 52 on the side near the drilling structure 5. Two sliding grooves 68 are provided on both sides of the outer support ring 51. Limiting grooves 69 are provided on the top of the two sliding grooves 68 and on the side close to each other. A movable block 65 is provided inside the inner fixing frame 61. Movable grooves 66 are provided on both sides of the movable block 65. A control rod 67 is provided inside the movable grooves 66. An impact block 610 is also provided inside the inner fixing frame 61. The end of the impact block 610 extends... Between the outer support ring 51 and the inner support ring 52, an outer movable frame 62 is fitted around the inner fixed frame 61. Two control holes 63 are provided on both sides of the outer movable frame 62. The ends of control rods 67 extend through two adjacent limiting grooves 69 into adjacent control holes 63. Both ends of the control holes 63 are provided with inclined surfaces. An impact spring 64 located inside the outer movable frame 62 is provided on the side of the movable block 65 away from the drilling structure 5. A connecting rod 611 is hinged to the top of the outer movable frame 62, and a secondary gear 612 is rotatably mounted at the end of the connecting rod 611. The middle part of the secondary gear 612 is rotatably connected to the outer extension cylinder 73. When the secondary gear 612 meshes with the primary gear 86, the primary gear 86 drives the secondary gear 612 to rotate. When the secondary gear 612 rotates, it drives the outer movable frame 62 to reciprocate. When the outer movable frame 62 moves toward the drilling structure 5, it compresses the impact spring 64, causing the control rod 67 to be limited in the limiting groove 69, preventing the movable block 65 from moving inside the inner fixed frame 61. The outer movable frame 62 continues to move until the control hole 63 is away from the drilling structure. The inclined surface on one side of the control rod 67 squeezes the two control rods 67 apart and enters the sliding groove 68. The elastic force of the impact spring 64 pushes the movable block 65, causing the impact block 610 to strike the impact plate 54, which in turn crushes the coal. When the outer movable frame 62 moves away from the drilling structure 5, the inclined surface on the side of the control hole 63 close to the drilling structure 5 drives the control rod 67 to move. When the control rod 67 moves to the position of the limiting groove 69, the inclined surface on the side of the control hole 63 close to the drilling structure 5 squeezes the control rod 67 into the limiting groove 69, thus achieving reset.

[0101] The striking structure 6 and the striking drilling structure 5 cause the impact plate 54 to strike the ore and crush it.

[0102] Furthermore, such as Figure 3 As shown, a sealing cover 4 is installed on one side of the outer casing 1 and is fitted outside the rigid tube 2. A connecting pipe is provided on the first partition 12 below the filter screen 14. The other end of the connecting pipe is connected to the top of the second partition 13. Gas enters from below the filter screen 14 to above the second partition 13. The infrared emitting module and the infrared receiving module are both located below the sealing cover 4.

[0103] Filter the gas inside the input casing 1.

[0104] Example 4

[0105] Please refer to Figure 13 A method for preventing and controlling gas in mines, comprising the following steps:

[0106] S1. Initial drilling: Connect the hard pipe 2 to the outlet pipe of the water pump 15, then move the outer shell 1 so that the drilling structure 5 is against the mining face. The water pump 15 delivers water to the water turbine 11. The water turbine 11 drives the drilling structure 5 to crush and cut the coal, while simultaneously pushing the outer shell 1 towards the mining face. When the coal seam is soft, the cutting method is used; when the coal seam is hard, the method of crushing first and then cutting is used.

[0107] A. During crushing, the second external gear ring 810 meshes with the first internal gear ring 74, restricting the rotation of the annular plate 72. The first-stage gear 86 meshes with the second-stage gear 612, driving the second-stage gear 612 to rotate. When the second-stage gear 612 rotates, it drives the outer movable frame 62 to reciprocate. When the outer movable frame 62 moves toward the drilling structure 5, it compresses the impact spring 64, causing the control rod 67 to be limited in the limiting groove 69, preventing the movable block 65 from moving inside the inner fixed frame 61. The outer movable frame 62 continues to move until it reaches the control hole 63. The inclined surface on the side away from the drilling structure 5 presses the control rod 67, causing the two control rods 67 to separate and enter the sliding groove 68. The elastic force of the impact spring 64 pushes the movable block 65, causing the impact block 610 to strike the impact plate 54, which in turn crushes the coal. When the outer movable frame 62 moves away from the drilling structure 5, the inclined surface on the side of the control hole 63 close to the drilling structure 5 drives the control rod 67 to move. When the control rod 67 moves to the position of the limiting groove 69, the inclined surface on the side of the control hole 63 close to the drilling structure 5 presses the control rod 67 into the limiting groove 69, thus achieving reset.

[0108] B. During cutting, when the second telescopic rod 84 shortens and pulls the connecting ring 75 away from the isolation cover 81, the distance between the second sealing ring 82 and the first sealing ring 79 increases. The side of the first sealing ring 79 away from the second sealing ring 82 is connected to the liquid delivery pipe 10. The end of the liquid delivery pipe 10 is connected to the hydraulic rod 55. Water inside the hydraulic rod 55 is pumped into the space between the first sealing ring 79 and the second sealing ring 82. The hydraulic rod 55 shortens, the impact plate 54 rotates and tilts to form an angle with the mining face, the first internal gear ring 74 and the second external gear ring 810 separate, the auxiliary gear 87 and the second internal gear ring 76 mesh, the first external gear ring 88 and the third internal gear ring 78 mesh. When the water turbine 11 drives the transmission pipe 85 to rotate, it drives the drilling structure 5 and the transmission structure 7 to rotate synchronously through the auxiliary gear 87 and the first external gear ring 88 respectively. The hydraulic rod 55 is used to cut the coal mine.

[0109] S2. After the hole is deepened and the moving structure 3 is inserted into the drilled channel, an extension pipe is installed between the hard pipe 2 and the water pump 15. Water is delivered to the inside of the water turbine 11 through the extension pipe to drive the drilling structure 5 to continue drilling.

[0110] S3. The advancing and moving structure 3 drives the drilling structure 5, the striking structure 6, and the transmission structure 7 to move into the channel. The first telescopic rod 315 drives the push plate 316 to move. The push plate 316 drives the connecting rod 317 to move. The connecting rod 317 drives the secondary sealing sleeve 312 to move. When the secondary sealing sleeve 312 moves towards the outer shell 1, the strip hole 313 connects with the connecting hose 318. The connection between the annular pipe 32 on the side away from the outer shell 1 and the primary sealing sleeve 311 is blocked by the secondary sealing sleeve 312. Water inside the secondary sealing sleeve 312 enters the annular pipe 32 near the outer shell 1 through the strip hole 313 and the connecting hose 318. Water inside the annular pipe 32 enters the adjacent first outer sleeve 3. 31 pushes the infusion channel 332, causing the inner slide rod 335 to move away from the rigid tube 2. The support plate 34 near the outer shell 1 abuts against the inner wall of the channel. The strip hole 313 continues to move towards the outer shell 1. The strip hole 313 and the connecting hose 318 remain connected. The connection between the annular tube 32 on the side away from the outer shell 1 and the first-stage sealing sleeve 311 is no longer blocked. Water enters the first-stage sealing sleeve 311 from the annular tube 32 and then enters the rigid tube 2 from the first-stage sealing sleeve 311. At this time, the first return spring 336, away from the outer shell 1, pushes the first piston disc 334 to move the inner slide rod 335 closer to the rigid tube 2. Water inside the second-stage sealing sleeve 312 continues to flow into the connecting hose 318. When one After the piston disc 334 passes through the infusion channel 332, water inside the first outer sleeve 331 enters the second outer sleeve 351, causing the moving rod 35 to extend and push the annular tube 32 away from the outer casing 1 to move. Then, the secondary sealing sleeve 312 moves away from the outer casing 1, and the strip hole 313 away from the outer casing 1 connects with the annular tube 32 away from the outer casing 1. The secondary sealing sleeve 312 blocks the connection between the connecting hose 318 and the primary sealing sleeve 311. Water inside the support structure 33 near the outer casing 1 cannot enter the primary sealing sleeve 311, and water inside the secondary sealing sleeve 312 enters the annular tube 32 away from the outer casing 1. The piston disc 334 on the side away from the outer casing 1 is pushed by gas, causing the support on that side to... The support plate 34 abuts against the inner wall of the channel and continues to move the secondary sealing sleeve 312 away from the outer shell 1. The connecting hose 318 communicates with the interior of the primary sealing sleeve 311. The first return spring 336 on the side closer to the outer shell 1 pushes the first piston disc 334 on that side and drains the water inside the first outer sleeve 331 into the interior of the primary sealing sleeve 311. The support plate 34 on that side no longer abuts against the inner wall of the channel. When the first piston disc 334 on that side passes through the infusion channel 332, the second return spring 354 pushes the second piston disc 352 and drains the water inside the second piston disc 352 through the second outer sleeve 351 from the drain port 333. Therefore, the moving rod 35 is shortened. The above steps are repeated to realize the movement of the moving structure 3 inside the channel.

[0111] S4. Retract, stop supplying water to the secondary sealing sleeve 312, move the connecting rod 317 so that the water in the support structure 33 near the outer shell 1 is discharged at the connection between the strip hole 313 and the connecting hose 318 and the primary sealing sleeve 311. Then the water inside the moving rod 35 is discharged through the drain port 333. The connection between the annular pipe 32 on the side away from the outer shell 1 and the primary sealing sleeve 311 corresponds to the outside of the secondary sealing sleeve 312, and the water inside flows out. The inner sliding rods 335 on the two annular pipes 32 retract towards the hard pipe 2. The support plate 34 separates from the inner wall of the channel. Pull the extension tube to pull out the moving structure 3 and the transmission structure 7.

[0112] S5. Evacuate the gas, remove the extension tube, move the outer shell 1 to insert the sealing cover 4 into the channel, and the air pump 9 runs to evacuate the gas. The gas enters the inner shell 1 from the inside of the channel through the sealing cover 4, and then passes through the filter screen 14 to filter impurities such as coal powder in the gas before passing through the first partition 12. The gas enters the upper part of the second partition 13 and is drawn by the air pump 9.

[0113] S6. Exhaust gas: Air pump 9 exhausts the extracted gas to the outside of the mine.

When the coal seam is soft, the cutting method is adopted, and when the coal seam is hard, the method of crushing first and then cutting is adopted. S2. After the hole is deepened and the moving structure (3) is submerged in the drilled channel, an extension pipe is installed. Water is then supplied to the water turbine (11) through the extension pipe to drive the drilling structure (5) to continue drilling. S3. The propulsion and moving structure (3) drives the drilling structure (5), the striking structure (6) and the transmission structure (7) to move into the channel; S4. Retract, stop supplying water to the inside of the moving structure (3), the moving structure (3) separates from the inner wall of the channel, and pull the extension tube to pull out the moving structure (3) and the transmission structure (7); S5. Evacuate air, remove the extension tube, move the outer casing (1) and insert the sealing cover (4) into the channel; S6. Exhaust gas, which discharges the extracted gas to the outside of the mine.
