Description

Technical Field

[0001] The invention relates to the technical field of disaster prevention, and in particular to a mine gas outburst rescue training system. Background Art

[0002] Gas outburst refers to a geological disaster caused by the fact that as the depth of coal mining increases and the gas content increases, the weak coal seam breaks through the resistance line under the action of ground stress and the gravity of gas release, instantly releasing a large amount of gas and coal. The deeper the coal mining depth, the greater the energy of gas released instantly. Coal and gas outbursts mainly occur during coal seam horizontal tunneling, mountain excavation and stone gate coal uncovering. In some mines, coal and gas outbursts also occur at the mining face.

[0003] Gas will undergo different changes and reactions in the air at different concentrations. For example, when the gas concentration is lower than 5%, it will not explode when it encounters fire, but it can form a combustion layer outside the flame; when the gas concentration is 9.5%, the gas can react completely with the oxygen in the air, thereby releasing the most heat, resulting in the maximum explosion intensity; when the gas concentration is higher than 16%, it cannot explode due to insufficient oxygen in the air; at this time, the gas will still burn when it encounters fire in the air, but it has lost its explosiveness. In addition, the hazards of gas also include that when the gas concentration in the air is very high, the oxygen content in the air will be relatively reduced, causing suffocation of people; when the gas explodes, it can produce a strong shock wave of high temperature and high pressure, causing casualties and damage to equipment and facilities; and the toxic and harmful gases produced by the explosion, such as carbon monoxide and carbon dioxide, will cause a large number of poisoning casualties.

[0004] Therefore, during the mining process in a mine, workers are required to undergo simulation training first in order to deal with gas outbursts in the mine. Only after passing the training can they participate in mine gas outburst rescue. During the training, gas needs to be released, and the trainees need to make different treatments based on the changes in gas concentrations. When detecting gas concentrations and the reactions to corresponding concentrations, they all need to be controlled and operated through an independent control unit. Therefore, precise operation of the equipment is required, or the trainer needs to pay attention to the gas concentration at all times and open the corresponding controller according to the gas concentration. This will increase the cost of simulation training or increase the labor intensity of the workers. Summary of the invention

The adjusting drive member includes a first adjusting member and a second adjusting member, the first adjusting member is used to open the first sealing plate 3, and the second adjusting member is used to open the channels of the fixed tube 24 and the diverter tube; gas is introduced through the air inlet pipe 21, and then a simulation component is used to simulate gas leakage, and the regulating component is passively driven to open by the movement of the simulation component, and different channels are passively opened according to the concentration of the gas, and scene training under different concentrations is carried out, which is convenient for trainees to carry out corresponding training, and there is no need for manual start-up by staff. The structure is simple and the operation is convenient, which reduces the cost of gas outburst simulation training and saves time and effort.

[0042] In an embodiment further provided by the present invention, the first adjusting member includes a support plate 41 fixed to the top of the fixed tube 24, the support plate 41 is rotatably connected to a roller 42, and sliding plates 43 are slidably arranged on the opposite sides of the two support plates 41, and the two first sealing plates 3 are fixedly connected to a connecting rope 48, the connecting rope 48 passes around the roller 42 and is fixedly connected to the sliding plate 43, and a protrusion is arranged on the sliding plate 43, and the protrusion is slidably arranged in the support plate 41 to ensure the sliding stability of the sliding plate 43, and the support spring 49 supports the sliding block so that the sliding block is located at the top, and the connecting rope 48 is used to ensure that the two first sealing plates 3 are in active contact to maintain the sealing effect.

[0043] Furthermore, a support spring 49 is fixedly connected to the bottom of the sliding plate 43 , and the support spring 49 is fixedly connected to the inner wall of the support plate 41 .

[0044] Furthermore, a snap-in plate 44 is slidably provided inside the sliding plate 43, and two driving blocks 47 are fixedly connected to the inner wall of the connecting tube 23. The driving blocks 47 and the sliding plate 43 are located on the same horizontal plane. After the driving blocks 47 move downward, they can contact the snap-in plate 44 and push the snap-in plate 44 to move. The snap-in plate 44 and the inner wall of the sliding plate 43 are fixedly connected with the same abutment spring 45. A wedge plate 46 is fixedly connected to the support plate 41, and the wedge plate 46 is slidably provided inside the sliding plate 43 and the snap-in plate 44.

[0045] In an embodiment further provided by the present invention, a smoke outlet plate 25 is fixedly connected to the bottom of the inner wall of the simulation chamber 1, and a plurality of smoke outlets 26 are opened on the smoke outlet plate 25. One side of the fixed tube 24 is connected to a limiting tube 28, and a trigger plate 29 is slidably arranged in the limiting tube 28. An LED row of lights 27 is arranged on one side of the fixed tube 24. Gas enters the smoke outlet plate 25 and is then discharged through the plurality of smoke outlets 26, thereby simulating a phenomenon in which gas burns without exploding. The trigger plate 29 is pushed to move by the gas entering the limiting tube 28, so that the LED row of lights 27 is powered on and flashes, thereby simulating a phenomenon in which the gas is in contact with oxygen in the air.

[0046] In the embodiment provided by the present invention, the second adjusting member includes a rotating plate 51 rotatably arranged in the fixed tube 24, the rotating axis of the rotating plate 51 extends to the outside of the fixed tube 24 and is fixedly connected to a gear 52, and the outside of the connecting tube 23 is fixedly connected to a rack 53 adapted to the gear 52, and the number of teeth of the rack 53 is the same as one-quarter of the number of teeth of the gear 52, so that during the movement of the rack 53, the gear 52 is driven to rotate 90 degrees, thereby switching between the fixed tube 24 and the limiting tube 28.

[0047] Specifically, a through hole 54 is opened on one side of the fixed pipe 24, and the size of the through hole 54 is adapted to the rotating plate 51. The gas is diverted by the rotation of the rotating plate 51, and different channels are passively opened according to different gas concentrations.

[0048] The solution further provided by the present invention also includes an unlocking component, which passively closes the channel when the connecting pipe 23 moves, and promptly closes the fixed pipe 24 after the gas stops flowing into the intake pipe 21. The unlocking component includes a connecting plate 61 fixed to the support plate 41, and an L-shaped plate 62 is rotatably connected to the connecting plate 61, and a locking plate 63 is rotatably connected to the L-shaped plate 62. The L-shaped plate 62 is in active contact with the locking plate 63, and can rotate downward when the locking plate 63 rotates counterclockwise, and cannot rotate due to the interference of the L-shaped plate 62 when the locking plate 63 rotates clockwise.

[0049] In the present invention, a torsion spring 64 is provided on one side of the locking plate 63, and the torsion spring 64 is connected to the L-shaped plate 62. The torsion spring 64 generates an elastic force on the locking plate 63, so that the locking plate 63 is kept horizontally set, so that the sliding plate 43 can be limited after the sliding plate 43 is located below the locking plate 63.

[0050] In the present invention, a safety door 11 is hinged on one side of the simulation chamber 1, and the safety door 11 is used to seal the simulation chamber 1 to ensure that the gas will not leak, thereby ensuring the safety of the simulation.

[0051] When in use, gas is introduced into the air inlet pipe 21, and the gas entering the air inlet pipe 21 pushes the connecting pipe 23 downward, thereby driving the driving block 47 to move synchronously. When the driving block 47 moves to contact the clamping plate 44, it continues to push the clamping plate 44 downward, thereby driving the sliding plate 43 to move synchronously, so that the connecting rope 48 moves downward, thereby pulling the first sealing plate 3 to rotate, thereby opening the fixed pipe 24;

[0052] After the fixing tube 24 is opened, the gas enters the limiting tube 28 through the through hole 54, thereby pushing the trigger plate 29 to move, and the trigger plate 29 turns on the LED row of lights 27, so that the LED row of lights 27 emit flashing lights, thereby simulating a gas explosion;

[0053] When the sliding plate 43 moves downward, the sliding plate 43 moves to the outside of the wedge plate 46. Since the wedge plate 46 is inclined, the clamping plate 44 is pushed inward, so that the abutment spring 45 is compressed. At the same time, the downward movement of the sliding plate 43 compresses the support spring 49. When the clamping plate 44 is completely moved into the sliding plate 43, the clamping plate 44 moves out of the driving block 47.

[0054] At the same time, after the sliding plate 43 moves downward, the locking plate 63 is pushed to rotate. When the driving block 47 moves out of the clamping plate 44, the locking plate 63 is pushed to rotate and reset by the torsion spring 64. When the driving block 47 moves out of the clamping plate 44, the sliding plate 43 is pulled upward by the support spring 49, so that the sliding plate 43 abuts against the locking plate 63, limiting the position of the sliding plate 43, thereby ensuring that the first sealing plate 3 is in an open state.

[0055] When the concentration of the intake pipe 21 increases, the sliding pipe 22 continues to move downward, driving the connecting pipe 23 to move downward, thereby driving the rack 53 to move synchronously. The rack 53 moves downward and meshes with the gear 52, and then continues to move downward, driving the gear 52 to rotate, thereby driving the rotating plate 51 to rotate synchronously, closing the through hole 54 and opening the fixed pipe 24, so that the gas enters the fixed pipe 24, then enters the smoke outlet plate 25, and finally is discharged through the smoke outlets 26, simulating the phenomenon that the gas concentration is the highest and only burns but does not explode;

[0056] When the simulation is completed, the sliding tube 22 and the connecting tube 23 move up to reset, driving the driving block 47 to move up synchronously, and then the L-shaped plate 62 is rotated to make the locking plate 63 move out of the sliding plate 43, and the elastic release of the supporting spring 49 and the abutting spring 45 drives the sliding plate 43 to move to the top, and at the same time, the abutting spring 45 pushes the clamping plate 44 to move out of the sliding plate 43, and the two first sealing plates 3 are closed through the connecting rope 48.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
