Description

Technical Field

[0001] The present invention relates to the technical field of poisonous gas purification, and in particular to an intelligent interception device and method for rapidly eliminating carbon monoxide in a coal mine. Background Art

[0002] Blasting is commonly used to develop tunnels. However, a large amount of CO poisonous gas is produced during the blasting process, which has always been an important risk factor threatening the life safety of workers. The affinity of CO to hemoglobin in the blood is 200 to 300 times higher than that of oxygen. It is very easy to combine with hemoglobin in human blood to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying capacity, thereby causing tissue asphyxiation and death. When the CO concentration in the environment exceeds 100ppm, the human body will experience discomfort such as dizziness and fatigue. When the CO concentration exceeds 600ppm, it will cause suffocation and death in a short period of time.

[0003] The underground ventilation system is the most basic measure to reduce the CO generated by blasting operations. The underground ventilation system includes mechanical ventilation and natural ventilation. However, due to the complexity of the tunnels, the poor operating stability of the ventilation equipment and the rapid diffusion of gas, it is difficult to eliminate the toxic CO gas generated by blasting operations by ventilation alone.

[0004] At present, researchers use spraying devices to spray the elimination agent to achieve the purpose of eliminating CO. However, most of the existing spraying devices are for locating and eliminating CO, so it is necessary to set up multiple spraying devices in the application scene to locate and eliminate CO at different locations.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1-2 As shown, the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to an embodiment of the present invention includes a connecting component 1, a spraying component 2 and a slide rail 33.

[0033] The slide rail 33 is disposed on the top surface of the tunnel (not shown) and extends along the extending direction of the tunnel.

[0034] The connecting assembly 1 is disposed on the slide rail 33 and moves relative to the slide rail 33 along the extending direction of the slide rail 33 .

[0035] The spraying assembly 2 includes a medicine-filled part 21 and a spraying part 22. The spraying part 22 is arranged on the connecting assembly 1 and is connected to the medicine-filled part 21. The spraying part 22 can rotate in the up-down direction relative to the connecting assembly 1. The up-down direction is orthogonal to the extension direction of the tunnel. The medicine-filled part 21 is connected to the spraying part 22 and is used to provide medicine to the spraying part 22. The medicine is used to eliminate CO.

[0036] In the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention, the spraying member 22 can move on the connecting component 1 relative to the tunnel, thereby increasing the spraying range of the spraying member 22 and improving the working efficiency of the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention. The spraying member 22 can rotate in the up and down directions relative to the connecting component 1, thereby further increasing the spraying range of the spraying member 22, thereby further improving the working efficiency of the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention and realizing the effective elimination of CO by drugs.

[0037] Specifically, the slide rail 33 is fixedly mounted on the top surface of the lane and extends along the extension direction of the lane, which not only allows the slide rail 33 to be firmly mounted on the lane, but also allows the spray assembly 2 to be stable when moving on the slide rail 33. The slide rail 33 has a top surface, and the top surface of the slide rail 33 is in contact with and connected to the top surface of the lane, which increases the contact area between the slide rail 33 and the top surface of the lane, so that the slide rail 33 is more firmly mounted on the top surface of the lane. There are two slide rails 33, and the two slide rails 33 are arranged at intervals along the first direction, and the slide rails 33 extend along the extension direction of the lane. The slide rail 33 has a slide groove 331, and the slide groove 331 extends along the extension direction of the slide rail, and the slide grooves 331 on the two slide rails 33 are arranged relative to each other.

[0038] In some embodiments, the connection assembly 1 includes a sliding member 11 and a connecting member 12. The sliding member 11 is disposed on the slide rail 33 and is movable relative to the slide rail 33. The connecting member 12 connects the sliding member 11 and the spraying member 22, and the sliding member 11 can drive the connecting member 12 to move relative to the slide rail 33, so as to drive the spraying member 22 to move relative to the slide rail 33.

[0039] Specifically, the sliding member 11 includes a connecting shaft 111 and rollers (not shown) respectively arranged at both ends of the connecting shaft 111. The connecting shaft 111 extends along a first direction, one of the rollers is slidably mounted in a slide groove 331 of one of the slide rails 33 and is not easily disengaged from the slide groove 331, and the other roller is slidably mounted in a slide groove 331 of another slide rail 33 and is not easily disengaged from the slide groove 331, so that the sliding member 11 is firmly mounted on the slide rail 33, thereby ensuring that the spraying member 22 is more stable when moving along the extension direction of the slide rail 33. A first motor (not shown) is arranged inside the roller, and the first motor is used to drive the roller to move on the slide rail 33, so that the roller is easy to operate when moving on the slide rail 33.

[0040] Specifically, the connecting member 12 includes a first connecting rod 121 and a second connecting rod 122. There are two first connecting rods 121, and the two first connecting rods 121 are arranged on the connecting shaft 111 at intervals along the first direction. The upper ends of the first connecting rods 121 are connected to the connecting shaft 111, and the lower ends of the first connecting rods 121 extend in the downward direction. The second connecting rod 122 extends along the first direction and is arranged between the two first connecting rods 121, and the second connecting rod 122 connects the two first connecting rods 121. As a result, the structure of the connecting assembly 1 is simple and cost-saving.

[0041] In some embodiments, the intelligent interception device for rapid elimination of carbon monoxide in coal mines further includes a controller 31 and a sensor 32 .

[0042] The controller 31 is connected to the sliding member 11 and the spraying member 22 . The controller 31 can control the moving speed of the sliding member 11 on the slide rail 33 and the rotation speed of the spraying member 22 relative to the connecting member 12 .

[0043] Specifically, the controller 31 is disposed on the second connecting rod 122 and is connected to the first motor inside the roller. The controller 31 drives the roller to move on the slide rail 33 by controlling the first motor.

[0044] The sensor 32 is used to detect the CO concentration in the tunnel. When the sensor 32 detects that the CO concentration in the tunnel exceeds a set threshold, the sensor 32 transmits a CO concentration signal to the controller 31 so that the controller 31 controls the spraying member 22 to spray medicine at this position.

[0045] Specifically, the sensor 32 is arranged on the controller 31, and when the sensor 32 detects that the CO concentration in the tunnel reaches the set threshold, the sensor 32 transmits the CO concentration signal to the controller 31 and also issues an alarm to remind the personnel. Therefore, the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention can intelligently detect and eliminate the CO concentration in the tunnel.

[0046] Specifically, the controller 31 can control the moving speed and spraying speed of the spraying member 22 at the next moment according to the CO concentration. When the sensor 32 detects that the CO concentration in the lane is far greater than the set threshold, the controller 31 not only controls the moving speed of the spraying member 22 at the current position to slow down, but also controls the speed of the spraying member 22 rotating in the up and down directions at the current position to slow down, so as to spray more medicine at this position and eliminate the CO at this position more quickly and effectively.

[0047] When the sensor 32 detects that the CO concentration in the tunnel is close to the set threshold, the controller 31 does not adjust the moving speed of the spraying member 22 in the extension direction of the slide rail 33 and the rotation speed in the up and down directions, so as to efficiently and quickly eliminate the CO at this position.

[0048] In some embodiments, the set threshold value of CO gas concentration is 24ppm. When the sensor 32 detects that the CO gas concentration in the tunnel exceeds 24ppm, the controller 31 controls the spraying member 22 to move toward the place where the CO gas concentration is the highest and sprays the medicine at this position to eliminate the CO gas concentration. When the sensor 32 detects that the set threshold value of the CO gas concentration at this position is less than or equal to 24ppm, the controller 31 controls the spraying member 22 to return to the original position and stops the spraying member 22 from spraying the medicine. As a result, the intelligent interception device for rapid elimination of carbon monoxide in coal mines according to the embodiment of the present invention is more accurate, intelligent and rapid in eliminating CO gas in the tunnel.

[0049] In some embodiments, the intelligent interception device for rapid elimination of carbon monoxide in coal mines further comprises a ventilation assembly 4. The ventilation assembly 4 comprises an air supply member (not shown), a first branch pipe 41 and a second branch pipe 42, wherein the air supply member is used to supply air to the first branch pipe 41 and the second branch pipe 42.

[0050] Specifically, the air supply parts are arranged in the tunnel, and the wind blown out by the air supply parts is the wind in the ventilation system of the mine itself, so as to reasonably utilize the resources of the mine itself, without providing additional power to generate wind, thus saving costs.

[0051] The first branch pipe 41 extends along a first direction, which is orthogonal to the extension direction and the up-down direction of the lane. One end of the second branch pipe 42 (such as Figure 1 The upper end of the second branch pipe 42 shown in FIG. 4 is connected to the first branch pipe 41, and the other end of the second branch pipe 42 (as shown in FIG. Figure 1 The lower end of the second branch pipe 42 shown in the figure extends in the downward direction and is connected to the spraying member 22 , and the medicine-filled member 21 is in communication with the second branch pipe 42 .

[0052] Specifically, the lower end of the first connecting rod 121 is connected to the outer wall surface of the first branch pipe 41 to connect the first branch pipe 41 and the connecting shaft 111. The first branch pipe 41 has an air inlet 411, and the air supply member is connected to the air inlet 411 to supply air into the first branch pipe 41. The upper end of the second branch pipe 42 is connected to the first branch pipe 41, and the lower end of the second branch pipe 42 extends in a downward direction and is connected to the spraying member 22. The wind in the first branch pipe 41 flows out of the spraying member 22 after passing through the second branch pipe 42, so that the medicine in the spraying member 22 can be blown around by the wind, thereby increasing the spraying range of the spraying member 22.

[0053] In some embodiments, the intelligent interception device for rapid elimination of carbon monoxide in a coal mine also includes an air volume regulating valve 5, which is arranged at the air inlet 411 of the first branch pipe 41 to control the closing of the air inlet 411 and the wind pressure of the air supply component to the first branch pipe 41, so as to better control the air volume entering from the first branch pipe 41 to the second 42, and further better control the spraying of the medicine in the spray component 22.

[0054] In some embodiments, there are at least two second branch pipes 42 , and the at least two second branch pipes 42 are arranged at intervals along the extending direction of the first branch pipe 41 .

[0055] Specifically, there are three second branch pipes 42, which are arranged at intervals along the extension direction of the first branch pipe 41. There are three spraying assemblies 2, which are arranged one by one with the three second branch pipes 42. When the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention is working, the three spraying assemblies 2 can simultaneously spray drugs in the tunnel to eliminate CO, thereby improving the working efficiency of the intelligent interception device for rapid elimination of carbon monoxide in a coal mine according to the embodiment of the present invention.

[0056] In some embodiments, the spraying member 22 includes a rotating member 221 and a first spray member 222. The rotating member 221 connects the first spray member 222 and the other end of the second branch pipe 42. The rotating member 221 can rotate in the up and down directions relative to the second branch pipe 42 to drive the first spray member 222 to rotate in the up and down directions relative to the second branch pipe 42. The medicine in the medicine-filled member 21 is sprayed out from the first spray member 222 through the second branch pipe 42.

[0057] Specifically, the controller 31 is connected to the rotating member 221 to control the rotating member 221 to rotate in the up and down directions relative to the second branch pipe 42, so that the rotating member 221 drives the first spray member 222 to rotate in the up and down directions relative to the second branch pipe 42, so that the range of spraying of the first spray member 222 is increased, thereby making the intelligent interception device for rapid elimination of carbon monoxide in coal mines of the embodiment of the present invention more efficient in eliminating CO.

[0058] Specifically, the first spray element 222 includes a first spray pipe 2221 and a first spray head 2222 . The upper end of the first spray pipe 2221 is connected to the second branch pipe 42 , and the lower end of the first spray pipe 2221 is connected to the first spray head 2222 . The medicine is sprayed out through the first spray head 2222 .

[0059] In some embodiments, the spraying member 22 includes a driving member 224 and a second spraying member 223. The second spraying member 223 is connected to the other end of the second branch pipe 42, and the medicine in the medicine-filling member 21 is sprayed out from the second spraying member 223 through the second branch pipe 42. The driving member 224 is used to drive the second spraying member 223 to rotate in an up-down direction relative to the second branch pipe 42.

[0060] Specifically, the controller 31 is connected to the driving member 224 to control the driving member 224 to rotate in the up-down direction relative to the second branch pipe 42. The driving member 224 includes a second motor 2241, a first gear 2242, and a second gear 2243. The output shaft of the second motor 2241 is connected to the first gear 2242 to drive the first gear 2242 to rotate in the up-down direction, and the second gear 2243 is connected to the second spraying member 223 and cooperates with the first gear 2242, so that the first gear 2242 can drive the second gear 2243 to rotate in the up-down direction, thereby driving the second spraying member 223 to rotate in the up-down direction relative to the second branch pipe 42, thereby, the operation process of the spraying member 22 is simple when it is working.

[0061] In some embodiments, the second spray piece 223 has a main body 2231, a first pipeline 2232, a second pipeline 2233 and a third pipeline 2234, the first pipeline 2232, the second pipeline 2233 and the third pipeline 2234 are connected to one end of the main body 2231, the other end of the main body 2231 is connected to the other end of the second branch pipe 42, the second pipeline 2233 is located between the first pipeline 2232 and the third pipeline 2234 and is arranged at intervals, and the first pipeline 2232 and the third pipeline 2234 extend in directions away from each other.

[0062] Specifically, the upper end of the body 2231 is connected to the lower end of the second branch pipe 42, and the second gear 2243 is connected to the upper end of the body 2231. The upper ends of the first pipeline 2232, the second pipeline 2233 and the third pipeline 2234 are connected to the lower end of the body 2231, and the lower ends of the first pipeline 2232 and the third pipeline 2234 extend in directions away from each other, thereby expanding the spraying range of the second sprayer 223 spraying the medicine.

[0063] Specifically, the second spray element 223 also includes three second spray heads 2235 , which are respectively arranged at the lower ends of the first pipeline 2232 , the second pipeline 2233 and the third pipeline 2234 , so that the medicine is sprayed out through the second spray heads 2235 .

[0064] In some embodiments, the medicine-filling member 21 has a chamber 211 , which is in communication with the second branch pipe 42 . The chamber 211 contains medicine, and the medicine is sprayed out from the spraying member 22 through the second branch pipe 42 .

[0065] Specifically, the medicine in the chamber 211 flows into the second branch pipe 42 , and the wind in the second branch pipe 42 blows the medicine into the spraying member 22 and sprays it out from the spraying member 22 .

[0066] In some embodiments, a stirrer (not shown) is provided in the chamber 211, and the stirrer is used to stir the medicine in the chamber 211. Specifically, the stirrer makes it difficult for the medicine in the chamber 211 to stick together, so as to facilitate the medicine to flow from the chamber 211 into the second branch 42.

[0067] In some embodiments, a flow meter (not shown) is further disposed in the chamber 211 , and the flow meter is used to online monitor the flow rate of the drug in the chamber 211 when it is sprayed out.

[0069] The intelligent interception method for rapidly eliminating carbon monoxide in a coal mine according to an embodiment of the present invention comprises:

[0070] A slide rail 33 is arranged on the top of the lane. Specifically, the slide rail 33 is fixedly installed on the top surface of the lane and extends along the extension direction of the lane, so that the slide rail 33 is firmly installed on the lane.

[0071] The spray assembly 2 is mounted on the slide rail 33. Specifically, the spray member 22 is mounted on the slide rail 33 through the connecting assembly 1, so that the spray member 22 can move synchronously with the connecting assembly 1 on the slide rail 33 along the extension direction of the slide rail 33.

[0072] A controller 31 and a sensor 32 are provided. The controller 31 and the sensor 32 are provided on the spray assembly 2. The controller 31 is used to control the movement of the spray assembly 2 on the slide rail 33. The sensor 32 is used to detect the CO concentration in the tunnel. When the CO concentration in the tunnel exceeds a set threshold, the sensor 32 transmits a CO concentration signal to the controller 31 so that the controller 31 controls the spray assembly 2 to spray the medicine.

[0073] Specifically, when the sensor 32 detects that the CO concentration in the tunnel exceeds 24 ppm, the sensor 32 transmits a CO concentration signal to the controller 31 so that the controller 31 controls the spraying member 22 to spray medicine at this position.

[0074] In addition, when the sensor 32 detects that the CO gas concentration in the tunnel exceeds 24ppm, the controller 31 can control the spraying member 22 to move toward the location where the CO gas concentration is the highest and spray the drug there to eliminate the CO gas concentration. When the sensor 32 detects that the CO gas concentration at the location is less than or equal to the set threshold of 24ppm, the controller 31 controls the spraying member 22 to return to the original position and stops spraying the drug.

[0075] The intelligent interception method for rapid elimination of carbon monoxide in coal mines in the embodiment of the present invention can eliminate CO gas in the tunnel quickly, efficiently and over a large area.
