Description

Technical Field

[0001] This invention relates to the field of extraction device technology, and in particular to a rapid gas extraction device. Background Technology

[0002] my country has a widespread network of fractured, soft, and low-permeability coal seams, which are typically characterized by high gas content, high pressure, coal seam fracturing, and complex geostress conditions. Statistics show that approximately one-third of the mines nationwide are high-gas or coal and gas outburst mines. With continuous advancements in gas control concepts, technologies, and equipment, coal mine gas disasters in my country have been effectively contained, and the overall trend of coal mine gas accidents is declining. However, in recent years, major and serious gas accidents still occur from time to time, and gas disasters remain a major hazard factor in mine safety production.

[0003] For fractured and soft coal seams with strong outburst potential, a common approach is to use roof and floor rock roadways combined with dense cross-layer drilling for strip gas drainage to mitigate outbursts. However, compared to roof and floor rock strata and medium-hard coal seams, fractured and soft coal seams are characterized by low elastic modulus, high Poisson's ratio, and high gas pressure. These characteristics lead to high perforation intensity and large amounts of coal slag being discharged during gas drainage drilling, carrying gas that diffuses into the mining space. This can easily cause gas levels to exceed limits in the working area, potentially resulting in personal injury and threatening safe mine production. Summary of the Invention

[0008] Preferably, an arm plate is fixedly connected to the main shaft, and a rod is movably inserted into the arm plate. One end of the rod is fixedly connected to a collar, and a first spring is sleeved on the rod. The two ends of the first spring are fixedly connected to one side of the arm plate and one side of the collar, respectively. Limiting plates are fixedly installed on both sides of the base, and insertion holes are opened on the limiting plates. The other end of the rod is inserted into the insertion hole.

[0009] Preferably, the movable component includes a receiving groove located at the center of the top surface of the device body, storage slots on both sides of the device body, a side rod fixedly connected to the inner wall of the storage slot, a pair of sleeve blocks slidably connected to the side rod, a second spring sleeved on the side rod, and the two ends of the second spring being fixedly connected to the inner wall of the storage slot and one side of the sleeve block, respectively.

[0010] Preferably, a driven block is fixedly connected to the bottom surface of the sleeve block, the driven block is slidably connected to the slide plate, both ends of the slide plate are fixedly connected to the inner wall of the storage slot, a first hinge seat is fixedly installed on one side of the sleeve block, a linkage plate is rotatably connected to the first hinge seat, the other end of the linkage plate is rotatably connected to a second hinge seat, and the second hinge seat is fixedly installed on the side plate.

[0011] Preferably, a plurality of rotating shafts are rotatably connected to the side plate, and rollers are fixedly installed on the rotating shafts.

[0012] Preferably, the drive assembly includes a drive motor fixedly installed inside the receiving groove, a transmission rod fixedly connected to the output end of the drive motor, a first pulley fixedly connected to the top end of the transmission rod, and a transmission belt sleeved on the first pulley.

[0013] Preferably, the transmission belt is attached to the first driven wheel, the first driven wheel is rotatably connected to the adjustment plate, the adjustment plate is provided with a sliding groove, a slider is slidably connected inside the sliding groove, the slider is fixedly installed on the device body, a column is fixedly connected to the adjustment plate, a push plate is rotatably connected to the column, the other end of the push plate is rotatably connected to a limiting post, and the bottom end of the limiting post is fixedly connected to the linkage plate.

[0015] In summary, the present invention has the following beneficial effects: 1. The present invention has a reasonable structure. When installing the extraction tube, the extraction tube is placed inside the arc-shaped groove, and then the L-shaped groove on the docking seat is engaged with the first pin. The foam block on the clamping plate is attached to the surface of the extraction tube, and then the pressure plate is attached to the second pin. The arm plate is rotated, and the rotation of the arm plate causes the pressure plate to press down on the second pin on the clamping plate, so that the clamping plate firmly fixes the extraction tube inside the arc-shaped groove. Then, the elastic force of the first spring causes one end of the insertion rod to be inserted into the insertion hole for fixation. This facilitates the extraction of underground gas without the need to carry the gas, avoiding the problem of excessive pressure.

[0016] 2. In this invention, a pair of side plates are respectively located on both sides of the device body. When the device body is placed inside the pipe, the side plates are first squeezed so that the distance between the side plates is the same as the inner diameter of the underground pipe. The squeezing of the side plates causes the linkage plate to push the sleeve block to slide on the side rod, thereby facilitating the pulling of the second spring. When the device body is placed in the underground pipe, the elastic force of the second spring causes the rollers on the side plates to fit tightly against the inner wall of the pipe, thereby facilitating the movement of the device body inside the underground pipe.

[0017] 3. In this invention, when the device body drives the extraction pipe into the ground to extract gas, the drive motor starts to operate. The operation of the drive motor causes the transmission rod to rotate, which in turn drives the first pulley to rotate. The rotation of the first pulley drives the second pulley to rotate through the transmission belt, thus facilitating the rollers on the rotating shaft to roll against the inner wall of the underground pipeline. As the side plate moves, the first driven wheel moves along with the linkage plate, preventing the transmission belt from falling off. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0022] Example: Reference Figure 1 - Figure 8The gas extraction device shown includes a device body 1, a base 101 fixedly installed at the center of the bottom surface of the device body 1, an arc-shaped groove 102 opened at the bottom surface of the base 101, an extraction tube 103 disposed inside the arc-shaped groove 102, an extraction head 104 installed at one end of the extraction tube 103, a foam block 105 attached to the surface of the extraction tube 103, and the foam block 105 fixedly installed on the inner wall of the clamping plate 106; it also includes a fastening component, a moving component and a driving component, the fastening component is disposed on the base 101 for mounting the clamping plate 106, the moving component is disposed on both sides of the device body 1 for use, and the driving component is mounted on the device body 1 for use in conjunction with the fastening component.

[0023] Specifically, it should be noted that the drive motor 4 is electrically connected to the existing control unit via wires. The specific details are based on existing technology and will not be elaborated on here. When using the device body 1 as a whole, the inner wall of the hole needs to be reinforced with pipes to prevent the underground from collapsing during use. Then, the device body 1 as a whole drives the extraction pipe 103 into the ground to collect the gas.

[0024] In one embodiment of this invention, the fastening assembly includes a pair of mating seats 2 fixedly mounted on the clamping plate 106. The pair of mating seats 2 have L-shaped grooves 201. A first pin 202 is engaged inside the L-shaped groove 201 and is fixedly connected to the base 101. Second pins 203 are fixedly connected to both sides of the clamping plate 106. A pressure plate 204 is attached to the surface of the second pins 203. One end of the pressure plate 204 is fixedly connected to the main shaft 205, and one end of the main shaft 205 is rotatably connected to... On the base 101, an arm plate 206 is fixedly connected to the main shaft 205. A rod 207 is movably inserted into the arm plate 206. A collar 208 is fixedly connected to one end of the rod 207. A first spring 209 is sleeved on the rod 207. The two ends of the first spring 209 are fixedly connected to one side of the arm plate 206 and one side of the collar 208, respectively. Limiting plates 210 are fixedly installed on both sides of the base 101. Insertion holes 211 are opened on the limiting plates 210. The other end of the rod 207 is inserted into the insertion hole 211.

[0025] Specifically, when installing the extraction tube 103, the extraction tube 103 is placed inside the arc-shaped groove 102, and then the L-shaped groove 201 on the docking seat 2 is engaged with the first pin 202. The foam block 105 on the clamping plate 106 is attached to the surface of the extraction tube 103, and then the pressure plate 204 is attached to the second pin 203 to rotate the arm plate 206. The rotation of the arm plate 206 causes the pressure plate 204 to press down on the second pin 203 on the clamping plate 106, so that the clamping plate 106 tightly fixes the extraction tube 103 inside the arc-shaped groove 102. Then, the elastic force of the first spring 209 causes one end of the insertion rod 207 to be inserted into the insertion hole 211 for fixing.

[0026] In one embodiment of this invention, the movable component includes a receiving groove 3 located at the center of the top surface of the device body 1. Storage grooves 301 are provided on both sides of the device body 1. Side rods 302 are fixedly connected to the inner walls of the storage grooves 301. A pair of sleeve blocks 303 are slidably connected to the side rods 302. A second spring 304 is sleeved on the side rods 302. The two ends of the second spring 304 are fixedly connected to the inner wall of the storage groove 301 and one side of the sleeve block 303, respectively. A driven block is fixedly connected to the bottom surface of the sleeve block 303. 305, the driven block 305 is slidably connected to the slide plate 306, the two ends of the slide plate 306 are fixedly connected to the inner wall of the storage groove 301, a first hinge seat 307 is fixedly installed on one side of the sleeve block 303, a linkage plate 308 is rotatably connected to the first hinge seat 307, the other end of the linkage plate 308 is rotatably connected to the second hinge seat 309, the second hinge seat 309 is fixedly installed on the side plate 310, a number of sets of rotating shafts 311 are rotatably connected to the side plate 310, and rollers 312 are fixedly installed on the rotating shafts 311.

[0027] Specifically, the side plates 310 are provided with a pair of side plates respectively on both sides of the device body 1. When the device body 1 is placed inside the pipe, the side plates 310 are first squeezed so that the distance between the side plates 310 is the same as the inner diameter of the underground pipe. The squeezing of the side plates 310 causes the linkage plate 308 to push the sleeve block 303 to slide on the side rod 302, which facilitates the pulling of the second spring 304. When the device body 1 is placed in the underground pipe, the elastic force of the second spring 304 makes the rollers 312 on the side plates 310 fit tightly against the inner wall of the pipe.

[0028] In one embodiment of this invention, the driving assembly includes a drive motor 4 fixedly installed inside the receiving groove 3. A transmission rod 401 is fixedly connected to the output end of the drive motor 4. A first pulley 402 is fixedly connected to the top end of the transmission rod 401. A transmission belt 403 is fitted onto the first pulley 402 and adheres to a first driven wheel 404. The first driven wheel 404 is rotatably connected to an adjusting plate 405. A groove 406 is provided on the adjusting plate 405, and a slider 407 is slidably connected inside the groove 406. The slider 407 is fixedly installed on the device body 1. The adjusting plate 405 is fixedly connected to the column 408. The column 408 is rotatably connected to the push plate 409. The other end of the push plate 409 is rotatably connected to the limiting post 410. The bottom end of the limiting post 410 is fixedly connected to the linkage plate 308. The transmission belt 403 is sleeved on the second pulley 411. The second pulley 411 is fixedly connected to one of the rotating shafts 311. The transmission belt 403 is attached to the second driven wheel 412. The second driven wheel 412 is rotatably connected to the side plate 310.

[0029] Specifically, when the device body 1 drives the extraction pipe 103 into the ground to extract gas, the drive motor 4 starts to operate. The operation of the drive motor 4 causes the transmission rod 401 to rotate. The rotation of the transmission rod 401 drives the first pulley 402 to rotate. The rotation of the first pulley 402 drives the second pulley 411 to rotate through the transmission belt 403. This facilitates the roller 312 on the rotating shaft 311 to roll against the inner wall of the underground pipeline. As the side plate 310 moves, the first driven wheel 404 moves with the linkage plate 308, preventing the transmission belt 403 from falling off.

[0030] The working principle of this invention is as follows: When installing the extraction tube 103, the extraction tube 103 is placed inside the arc-shaped groove 102, and then the L-shaped groove 201 on the docking seat 2 is engaged with the first pin 202. The foam block 105 on the clamping plate 106 is attached to the surface of the extraction tube 103, and then the pressure plate 204 is attached to the second pin 203 to rotate the arm plate 206. The rotation of the arm plate 206 causes the pressure plate 204 to press down on the second pin 203 on the clamping plate 106, so that the clamping plate 106 tightly fixes the extraction tube 103 inside the arc-shaped groove 102. Then, the elastic force of the first spring 209 causes one end of the insertion rod 207 to be inserted into the insertion hole 211 for fixing. The side plates 310 are provided with a pair of side plates respectively on both sides of the device body 1. When the device body 1 is placed inside the pipe, the side plates 310 are first squeezed so that the distance between the side plates 310 is the same as the inner diameter of the underground pipe. The squeezing of the side plates 310 causes the linkage plate 308 to push the sleeve block 303 to slide on the side rod 302, which facilitates the pulling of the second spring 304. When the device body 1 is placed in the underground pipe, the elastic force of the second spring 304 makes the roller 312 on the side plate 310 fit tightly against the inner wall of the pipe. When the device body 1 drives the extraction pipe 103 into the ground to extract gas, the drive motor 4 starts to operate. The operation of the drive motor 4 causes the transmission rod 401 to rotate. The rotation of the transmission rod 401 drives the first pulley 402 to rotate. The rotation of the first pulley 402 drives the second pulley 411 to rotate through the transmission belt 403. This makes it easier for the roller 312 on the rotating shaft 311 to roll against the inner wall of the underground pipeline. As the side plate 310 moves, the first driven wheel 404 moves with the linkage plate 308 to prevent the transmission belt 403 from falling off.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
