[0022] Further, in order to ensure that the elastic components have good elastic performance and at the same time have good load-bearing capacity, the first elastic component, the second elastic component and the third elastic component are all combined springs of stainless steel corrugated springs and helical springs. The number of the first elastic components is 2 to 4, and the number of the second elastic components and the third elastic components are both 4 to 8.

[0023] In the present invention, the CO elimination mechanism is a multi-layer annular structure composed of a first charging cylinder body, a second charging cylinder body, and a third charging cylinder body. At the same time, an outer annular ventilation area is formed between the first charging cylinder body and the second charging cylinder body, and an inner annular ventilation area is formed between the second charging cylinder body and the third charging cylinder body, which facilitates the detonation gas to smoothly pass through the CO elimination mechanism through the outer annular ventilation area and the inner annular ventilation area. Since the first, second, and third charging cylinder bodies are respectively filled with CO elimination agent particles A, B, and C, and at the same time, through holes are provided on the cylinder bodies of each charging cylinder body, in this way, during the process of the detonation gas passing through the CO elimination mechanism, it can fully contact the CO elimination agent particles in the three charging cylinder bodies, so as to effectively eliminate the CO gas contained in the gas by using the CO elimination agent particles, achieving the purpose of quickly and efficiently removing toxic and harmful gases. The movable end cover is detachably covered at the right opening end of the main cylinder body, which facilitates opening or closing the movable cylinder body, and further facilitates loading or removing the CO elimination mechanism into or out of the movable cylinder body. A number of through holes are provided on the movable cylinder body, which facilitates the detonation gas to smoothly enter the CO elimination mechanism through the movable cylinder body. The second support plate is axially slidably sleeved outside the movable cylinder body through the circular hole two at its center. At the same time, a plurality of support rods surrounding the outer periphery of the movable cylinder body are used to connect the second support plate and the first support plate located on the left side of the movable cylinder body, so as to form a protection frame outside the movable cylinder body. In this way, not only can the movable cylinder body be protected, but also the movable cylinder body can slide axially relative to the protection frame. A connecting sleeve is connected to the right side of the first support plate, and a connecting stud is connected to the left side of the connecting cover, which facilitates the fixed connection of the connecting cover between the first support plate and the movable cylinder body through thread matching. Then, a plurality of first elastic connection components are used to connect the movable cylinder body and the connecting cover, so that while protecting the movable cylinder body by using the support frame, a buffering force can be provided for the axial movement process of the movable cylinder body through a plurality of first elastic components, improving the protection effect on the movable cylinder body. The front end plate and the rear end plate are oppositely arranged on the leftmost and rightmost sides, and a plurality of second elastic components are used to connect the front end plate and the first support plate, and a plurality of third elastic components are used to connect the rear end plate and the second support plate. Elastic acting forces can be provided for the movable cylinder body and the support frame by the cooperation of the second elastic components and the third elastic components, and further, the impact force during the blasting process can be effectively buffered, playing an effective role in protecting the CO elimination mechanism and the movable fixing mechanism.The outer ends of multiple fixing pins are all in a sharp conical structure. At the same time, the inner ends of the fixing pins are movably connected to the main cylinder body through hinge blocks, and in the normal state of the elastic components, the fixing pins are in an inclined state. In this way, when pushing the elimination system towards the bottom of the blast hole, it can ensure that the fixing pins can extend outwards by a certain length and can be smoothly inserted into the rock wall under the limiting action of the limiting baffle, which is beneficial to fixing the elimination system inside the blast hole. Combined with the buffering and protecting effects of multiple elastic components, the elimination system can be made to have the ability to resist the explosive blasting pressure and shock wave. At the same time, by using multiple first elastic components evenly distributed in the circumferential direction to connect the connection cover and the movable cylinder body, using multiple second elastic components evenly distributed in the circumferential direction to connect the front end plate and the connection cover, and using multiple third elastic components evenly distributed in the circumferential direction to connect the movable end cover and the rear end plate, the load-bearing capacity can be effectively enhanced in a parallel connection manner. At the same time, it can achieve good pressure relief and buffering effects, which is beneficial to providing multiple protections for the elimination system and enabling the elimination system to have the ability to be reused. Moreover, when the elimination system is fixed inside the blast hole, it can also help prevent the phenomenon of punching, which to a certain extent contributes to improving the blasting effect. In addition, during the blasting process, the CO elimination mechanism placed in the blast hole can effectively remove CO in the gas, achieving the effect of eliminating CO from the source.

[0024] The CO elimination effect of this system is ideal, the elimination efficiency is high. At the same time, it has strong anti-shock ability and self-protection ability. It can eliminate CO generated during the operation from the source, which is beneficial to improving the operation efficiency and can ensure the health and safety of workers' lives.

The connection cover 33 connected to the movable cylinder 11 through the first elastic component 35 is threadedly connected to the first support plate 17. During the process of the movable cylinder 11 being pressed inward, the second elastic component 40 is in a compressed state, and the fixing pin 28 extends outward along the perforation 26 on the support rod 19, and is restricted by the limit baffle 29 outside the perforation 26 and changes from an inclined state to a vertical state and is inserted into the wall surface of the blast hole 45.

[0063] During use, first, the multi-section explosive 44 is successively pushed to the bottom of the blast hole 45, and then the in-situ high-efficiency CO poisoning product elimination system is pushed into the blast hole 45. During this process, the rear end plate 34 in the pressure relief mechanism 3 is squeezed towards the bottom of the hole under the action of the thrust force. The third elastic component 40 is compressed and pushes the movable cylinder body 11 to move towards the bottom of the hole. The fixing pin 28 passing through the support rod 19 extends outwards under the drive of the movable cylinder body 11 and quickly anchors into the hole wall of the blast hole 45 under the limiting action of the limiting baffle 29. At this time, the first elastic component 35, the second elastic component 36, and the third elastic component 40 are all in a compressed state. Then, the plugging material 46 is blocked at the orifice of the blast hole 45; at the moment when the explosive 44 explodes, the generated detonation gas impact acts on the front end plate 32; during this process, the explosion impact force received by the whole system is buffered and eliminated through multiple second elastic components 36 and multiple third elastic components 40, and the impact force received by the movable cylinder body 11 is further buffered through multiple first elastic components 35, the second support plate 18 slidably matched with the movable cylinder body 11, and multiple fixing pins 28 anchored into the hole wall; meanwhile, the detonation gas successively enters the inside of the movable cylinder body 11 through several through holes six 41 on the front end plate 32, the round hole one 20 and several through holes four 23 on the first support plate 17, the round hole three 37 and several through holes five 38 on the connecting cover 33, several through holes one on the main cylinder body 12, and several through holes two on the fixed end cover 13, and comes into full contact with the first charging cylinder body 4, the second charging cylinder body 5, and the third charging cylinder body 6. Furthermore, the CO scavenger particles A, CO scavenger particles B, and CO scavenger particles C inside the first charging cylinder body 4, the second charging cylinder body 5, and the third charging cylinder body 6 fully act on the CO in the gas, realizing the high-efficiency elimination operation of CO in the gas. Among them, the gas after eliminating CO flows towards the orifice direction through several through holes three 16 on the movable end cover 14 and several through holes seven 42 on the rear end plate 34.

[0064] In the present invention, the CO elimination mechanism is a multi-layer annular structure composed of a first charging cylinder body, a second charging cylinder body, and a third charging cylinder body. At the same time, an outer annular ventilation area is formed between the first charging cylinder body and the second charging cylinder body, and an inner annular ventilation area is formed between the second charging cylinder body and the third charging cylinder body, which can facilitate the detonation gas to pass through the CO elimination mechanism smoothly through the outer annular ventilation area and the inner annular ventilation area. Since the first, second, and third charging cylinder bodies are respectively filled with CO elimination agent particles A, B, and C, and at the same time, through holes are provided on the barrel bodies of each charging cylinder body. In this way, during the process of the detonation gas passing through the CO elimination mechanism, it can fully contact the CO elimination agent particles in the three charging cylinder bodies, so that the CO gas contained in the gas can be effectively eliminated by the CO elimination agent particles, achieving the purpose of quickly and efficiently removing toxic and harmful gases. The movable end cover is detachably covered at the right opening end of the main cylinder body, which can facilitate the opening or closing of the movable cylinder body, and further facilitate the loading or removal of the CO elimination mechanism into or out of the movable cylinder body. A number of through holes are provided on the movable cylinder body, which can facilitate the detonation gas to pass through the movable cylinder body smoothly and enter the CO elimination mechanism. The second support plate is axially slidably sleeved outside the movable cylinder body through the circular hole two at its center. At the same time, a plurality of support rods surrounding the outer periphery of the movable cylinder body are used to connect the second support plate and the first support plate located on the left side of the movable cylinder body, so as to form a protection frame outside the movable cylinder body. In this way, not only can the movable cylinder body be protected, but also the movable cylinder body can slide axially relative to the protection frame. A connection sleeve is connected to the right side of the first support plate, and a connection stud is connected to the left side of the connection cover, which can facilitate the fixed connection of the connection cover between the first support plate and the movable cylinder body through threaded cooperation. Then, a plurality of first elastic connection components are used to connect the movable cylinder body and the connection cover, so that while protecting the movable cylinder body by using the support frame, a buffering force can be provided for the axial movement process of the movable cylinder body through a plurality of first elastic components, improving the protection effect on the movable cylinder body. The front end plate and the rear end plate are oppositely arranged on the leftmost and rightmost sides, and a plurality of second elastic components are used to connect the front end plate and the first support plate, and a plurality of third elastic components are used to connect the rear end plate and the second support plate. The elastic acting force can be provided for the movable cylinder body and the support frame through the cooperation of the second elastic components and the third elastic components, and further, the impact force during the blasting process can be effectively buffered, playing an effective role in protecting the CO elimination mechanism and the movable fixing mechanism.Make the outer ends of multiple fixing pins all be in a sharp conical structure. At the same time, make the inner ends of the fixing pins be movably connected to the main cylinder body through hinge blocks, and make the fixing pins be in an inclined state under normal conditions of the elastic components. In this way, when pushing the elimination system towards the bottom of the blast hole, it can be ensured that the fixing pins can extend outward by a certain length and can be smoothly inserted into the rock wall under the limiting action of the limiting baffle, which is beneficial to fixing the elimination system inside the blast hole. Combined with the buffering and protecting effects of multiple elastic components, the elimination system can be made to have the ability to resist the explosive blasting pressure and shock waves. At the same time, by using multiple first elastic components evenly distributed in the circumferential direction to connect the connecting cover and the movable cylinder body, using multiple second elastic components evenly distributed in the circumferential direction to connect the front end plate and the connecting cover, and using multiple third elastic components evenly distributed in the circumferential direction to connect the movable end cover and the rear end plate, the bearing capacity can be effectively enhanced in a parallel connection manner. At the same time, it can achieve a good pressure relief and buffering effect, which is beneficial to providing multiple protections for the elimination system and enabling the elimination system to have the ability to be reused. Moreover, when the elimination system is fixed inside the blast hole, it can also help prevent the phenomenon of punching, which to a certain extent contributes to improving the blasting effect. In addition, during the blasting process, the CO elimination mechanism placed in the blast hole can effectively remove CO in the gas, achieving the effect of eliminating CO from the source.

[0065] The CO elimination effect of this system is ideal, and the elimination efficiency is high. At the same time, it has strong anti-shock ability and self-protection ability. It can eliminate CO generated during the operation from the source, which is beneficial to improving the operation efficiency and can ensure the health and safety of workers' lives.
