Description

Technical Field

[0001] This utility model relates to the field of fire prevention technology in coal mine tunnels, specifically to a fire prevention indicator gas collection and sampling device. Background Technology

[0002] Two fire prevention observation points are set up in the coal mining face section, one in the coal pillar area and the other in the goaf area. Figure 1 As shown, because the fire prevention observation point 2 in the coal pillar area and the fire prevention observation point 1 in the goaf area are located in different positions, it is difficult to measure the fire-preventing gases in the goaf area and inside the coal pillar separately at the same location. This makes it impossible to determine whether a fire hazard at the same location is inside the goaf area or inside the coal pillar, and also makes it impossible to compare the fire-preventing gas indicators of the goaf area and the coal pillar area at the same location. Therefore, it is impossible to determine whether the fire hazard occurs inside the goaf area or in the coal pillar area, and the specific location of the fire hazard cannot be effectively distinguished, making it impossible to accurately carry out fire prevention work on the coal pillars in the coal mining face. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to effectively distinguish the specific location of fire hazards.

[0004] This utility model solves the above-mentioned technical problems through the following technical means:

[0005] This utility model provides a fire prevention index gas collection and sampling device, including an iron pipe that can pass through the coal pillar area and be placed in the goaf area. The iron pipe body has a perforated section, and a rubber tube is provided inside the iron pipe. The rubber tube is divided into a first rubber tube and a second rubber tube. The first rubber tube passes through the iron pipe and can measure the fire prevention index gas in the goaf area, while the second rubber tube placed in the perforated section of the iron pipe can measure the fire prevention index gas in the coal pillar area.

[0006] Beneficial effects: This utility model utilizes a fire indicator gas sampling device to sample and detect fire indicator gases in both coal pillar areas and goaf areas at the same location. If abnormalities are detected in the fire indicator gases, it is easy to determine whether the fire hazard is occurring in the goaf area or the coal pillar area. This solves the problem that setting up fire observation points in the coal pillar area cannot accurately reflect whether the fire hazard is in the goaf area or the coal pillar area.

[0007] Preferably, the inside of both ends of the iron pipe is sealed with anchoring agent.

[0008] Beneficial effects: The purpose of using anchoring agent to seal both ends of the iron pipe in this utility model is to prevent the fire prevention index gas in the goaf from entering the iron pipe at one end, and to prevent the fire prevention index gas from overflowing the iron pipe and to prevent air in the mine roadway from entering the iron pipe, so that only the fire prevention index gas in the coal pillar area is inside the iron pipe, and then the fire prevention index gas in the coal pillar can be sampled and taken out through the second hose.

[0009] Preferably, one end of the first tubing is cut into a first flower-shaped tube, and the end of the first flower-shaped tube is placed in the goaf.

[0010] Preferably, one end of the second tubing is cut into a second flower-shaped tube, and the end of the second flower-shaped tube is at the flower-shaped section of the iron pipe.

[0011] Beneficial effects: In order to prevent the tube ends of the tubing from becoming clogged, the ends of the first and second tubings are cut into a flower-shaped shape, which also facilitates sampling by the first and second tubings.

[0012] Preferably, both the first and second hoses are provided with valves at their other ends, and the valves are located outside the iron pipes.

[0013] Beneficial effects: This utility model has valves at both ends of the first and second hoses. After the sampling and measurement are completed, the valves can be closed to prevent air leakage from the first and second hoses into the goaf and coal pillar area.

[0014] Preferably, the anchoring agent is 0.5m away from the end of the iron pipe.

[0015] Preferably, the iron pipe is further provided with a perforated section after the anchoring agent.

[0016] Beneficial effects: By providing perforated pipe sections at both ends of the iron pipe, this utility model makes it more convenient for the second hose to collect fire-resistant index gas.

[0017] Preferably, the iron pipe is a 6-point iron pipe. Attached Figure Description

[0023] according to Figure 2-3 As shown, this embodiment provides a fire-prevention index gas sampling device, including an iron pipe 10. The iron pipe 10 can pass through the coal pillar area, with one end placed in the goaf area and the other end placed in the goaf roadway. The iron pipe 10 is a 6-point iron pipe capable of bearing pressure. The iron pipe 10 has perforated sections 14 on its body, with three perforated sections 14 located at locations 0.5m away from both ends of the iron pipe 10 and in the middle of the iron pipe 10, respectively. Figure 2 As shown.

[0024] The iron pipe 10 is equipped with a tubing, which is divided into a first tubing 11 and a second tubing 12. The first tubing 11 passes through the iron pipe 10, with one end in the goaf area, and is used to measure the fire-prevention index gas in the goaf area. In order to prevent the tube end of the first tubing 11 from being blocked during sampling, the tube end in the goaf area is cut into a first perforated tube shape 11a, which is also conducive to the sampling of the first tubing 11. The other end of the first tubing 11 is in the goaf roadway and is equipped with a valve 13. The valve 13 is located on the outside of the iron pipe 10. The function of setting the valve 13 on the first tubing 11 is to prevent the first tubing 11 from leaking air into the goaf area by closing the valve 13 after the sampling measurement is completed.

[0025] One end of the second hose 12 is placed inside the iron pipe 10 and is located at the perforated section 14 in the middle of the iron pipe 10. It is used to measure the fire-prevention index gas in the coal pillar area. Similarly, in order to prevent the pipe head of the second hose 12 from being blocked during sampling, the pipe head at the perforated section 14 is cut into a second perforated pipe shape 12a, which is also conducive to the sampling of the second hose 12. The other end of the second hose 11 is in the goaf roadway and is equipped with a valve 13. The valve 13 is located outside the iron pipe 10. The function of setting the valve 13 on the second hose 12 is to prevent the second hose 12 from leaking air into the coal pillar area by closing the valve 13 after the sampling measurement is completed.

[0026] The two ends of the iron pipe 10 are sealed with anchoring agent 15. The anchoring agent 15 is 0.5m away from the ends of the iron pipe 10. The purpose of the anchoring agent 15 in sealing the iron pipe 10 at the goaf end is to prevent the fire prevention index gas in the goaf from entering the iron pipe 10, which is beneficial for the first hose 11 to collect the fire prevention index gas in the goaf. The purpose of the anchoring agent 15 in sealing the iron pipe 10 at the goaf roadway end is to prevent the fire prevention index gas in the coal pillar area in the iron pipe 10 from overflowing the iron pipe 10, so that only the fire prevention index gas in the coal pillar area is inside the iron pipe 10, which is beneficial for the second hose 12 to collect the fire prevention index gas in the coal pillar area.

[0027] The working principle of the fire-prevention index gas sampling device in this embodiment is as follows:

[0028] like Figure 3 As shown, this embodiment combines two existing fire prevention observation points into one measurement point. The measurement point extends from the goaf roadway through the coal pillar area to the goaf. The fire prevention index gas sampling device of this embodiment is placed at the measurement point, with one end of the device in the goaf area and the other end in the goaf roadway. This allows for the simultaneous detection of fire prevention index gases in both the goaf and coal pillar areas. When there is an abnormality in the fire prevention index gas at the measurement point, by comparing the fire prevention index gases in the goaf and the coal pillar area, it can be clearly determined whether the fire hazard is occurring in the goaf or the coal pillar area.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
