Description

Technical Field

[0001] This invention relates to the field of underground gas monitoring technology, and in particular to an underground gas monitoring device. Background Technology

[0002] Mine gas refers to a general term for toxic and harmful gases, mainly methane, found underground, and sometimes specifically methane. Methane is lighter than air, diffuses easily, and has strong permeability, easily penetrating adjacent layers and passing through rock strata to be released from the goaf. Methane itself is not toxic, but it cannot be breathed. When the concentration of methane in the mine air exceeds 50%, it can cause people to suffocate and die due to lack of oxygen.

[0003] Chinese Patent Application No. 202221238134.3 discloses an underground gas monitoring device, which includes a housing, a gas monitoring probe, an audible and visual alarm, a display screen, a status indicator light, and a moisture-proof component. The gas monitoring probe is installed at the bottom of the housing, the audible and visual alarm is installed on the right side of the housing, and the display screen and status indicator light are both embedded in the front surface of the housing, with the display screen located above the status indicator light. The top of the housing has an installation opening, and a moisture-proof component is threadedly fixed at the installation opening. The housing contains a temperature and humidity sensor, a control host, a battery, and a LoRa wireless transmission device. The gas monitoring probe, audible and visual alarm, display screen, status indicator light, temperature and humidity sensor, battery, and LoRa wireless transmission device are all electrically connected to the control host.

[0004] However, the aforementioned underground gas monitoring device can only be fixedly installed in one location underground and can only monitor the gas concentration at that location, which has limitations in monitoring underground gas concentration. Therefore, in order to solve this problem, an underground gas monitoring device is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an underground gas monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An underground gas monitoring device includes an electric trolley, an electric push rod mounted on the top of the trolley, an installation plate mounted on the piston rod end of the electric push rod, an installation disc rotatably mounted on the side of the installation plate, a fixing plate mounted on the side of the installation disc, and gas concentration monitoring mechanisms for monitoring gas concentration on both sides of the fixing plate; the gas concentration monitoring mechanism includes a multi-stage electric telescopic rod mounted on the side of the fixing plate, a strip plate mounted on the piston rod end of the multi-stage electric telescopic rod, and a gas concentration monitoring component disposed between the strip plate and the fixing plate.

[0008] Preferably, the gas concentration monitoring component includes several mounting blocks disposed between the strip plate and the fixed plate. A gas concentration monitoring probe is installed on the side of the mounting block away from the mounting plate. The strip plate is connected to the end of the mounting blocks. The other end of the mounting blocks is installed on the side of the fixed plate. An elastic part is provided between each pair of adjacent mounting blocks. The elastic part includes a sleeve installed on the side of one of the mounting blocks in each pair of adjacent mounting blocks. A guide rod is slidably sleeved inside the sleeve. The end of the guide rod is installed on the side of the other mounting block. A spring is installed between the mounting blocks connected to the sleeve and the end of the guide rod. The guide rod is located in the inner ring of the spring.

[0009] Preferably, an elastic fabric is installed between the strip plate and the mounting plate. The elastic fabric has several openings, and a suction fan is installed in each opening. The suction end of the suction fan is located on the side of the elastic fabric closer to the multi-stage electric telescopic rod.

[0010] Preferably, mounting strips are installed on the opposite sides of the strip plate and the mounting plate, and the elastic cloth is installed between the two mounting strips.

[0011] Preferably, a motor is mounted on the side of the mounting plate near the mounting disk, and the output shaft of the motor is connected to the mounting disk.

[0012] Preferably, a fixing rod is installed on the side of the mounting plate near the mounting disk, and a slider is installed at the end of the fixing rod. An annular groove is formed on the side of the mounting plate near the mounting disk, and the slider is slidably installed in the annular groove.

[0013] Preferably, the electric cart is equipped with a controller and a buzzer alarm on its top, the gas concentration monitoring probe is electrically connected to the controller, and the controller and the buzzer alarm are electrically connected.

[0014] Preferably, a reinforcing block is installed at the end of the piston rod of the electric push rod, and the reinforcing block is installed at the bottom of the mounting plate.

[0015] Preferably, the electric cart has two counterweight boxes symmetrically installed on its top. The counterweight boxes are filled with sand. The top of the counterweight box has a feed inlet, and the side of the counterweight box has a discharge outlet. The electric push rod is located between the two counterweight boxes.

[0016] Preferably, the mounting block has a mounting groove on the side away from the multi-stage electric telescopic rod, and a mounting seat is installed in the mounting groove, with the gas concentration monitoring probe installed on the mounting seat.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, several uniformly distributed gas concentration monitoring probes rotate, allowing for the monitoring of gas concentration at a specific location within the mine during rotation. The probes are horizontally evenly distributed and monitor gas concentration throughout the mine, enabling comprehensive monitoring of the gas concentration at that location. Furthermore, the real-time rotation of these probes ensures comprehensive monitoring of gas concentration at that specific location within the mine, thus improving the overall comprehensiveness of gas concentration monitoring within the mine.

[0019] 2. In this invention, several mounting blocks move simultaneously away from the fixed plate, and the distance between two adjacent mounting blocks gradually increases, while the distance between any two adjacent mounting blocks is equal. The elasticity of the spring allows several mounting blocks to move simultaneously away from the fixed plate. Furthermore, the combined use of the spring, guide rod, and sleeve ensures that the distance between the several mounting blocks is equal, thereby unfolding the several mounting blocks. This unfolds the gas concentration monitoring probes mounted on the sides of the several mounting blocks, resulting in a uniform distribution of the gas concentration monitoring probes, with equal spacing between each gas concentration monitoring probe.

[0020] 3. In this invention, the suction fan draws air from the mine shaft, causing the air to flow towards the gas concentration monitoring probe. This facilitates rapid monitoring of the gas concentration in the mine shaft by the gas concentration monitoring probe. The gas flows towards the suction fan, passing through several gas concentration monitoring probes. These probes can then monitor the passing gas, thereby ensuring the efficiency of gas concentration monitoring in the mine shaft. Attached Figure Description

[0031] Reference Figure 1-7 An underground gas monitoring device includes an electric trolley 1, an electric push rod 5 mounted on the top of the electric trolley 1, an mounting plate 6 mounted on the piston rod end of the electric push rod 5, an mounting disk 9 rotatably mounted on the side of the mounting plate 6, a fixing plate 10 mounted on the side of the mounting disk 9, and gas concentration monitoring mechanisms for monitoring gas concentration on both sides of the fixing plate 10; the gas concentration monitoring mechanism includes a multi-stage electric telescopic rod 11 mounted on the side of the fixing plate 10, a strip plate 12 mounted on the piston rod end of the multi-stage electric telescopic rod 11, and a gas concentration monitoring component disposed between the strip plate 12 and the fixing plate 10.

[0032] As a technical optimization of the present invention, the gas concentration monitoring component includes a plurality of mounting blocks 20 disposed between the strip plate 12 and the fixed plate 10. A gas concentration monitoring probe 21 is mounted on the side of the mounting block 20 away from the mounting plate 9. The strip plate 12 is connected to the end of the mounting block 20 among the plurality of mounting blocks 20. The other end of the mounting block 20 among the plurality of mounting blocks 20 is mounted on the side of the fixed plate 10. An elastic part is provided between each pair of adjacent mounting blocks 20. The elastic part includes a sleeve 22 mounted on the side of one of the mounting blocks 20 in each pair of adjacent mounting blocks 20. A guide rod 23 is slidably sleeved in the sleeve 22. The end of the guide rod 23 is mounted on the side of the other mounting block 20. A spring 24 is installed between the sleeve 22 and the mounting block 20 connected to the end of the guide rod 23. The guide rod 23 is located in the inner ring of the spring 24.

[0033] As a technical optimization of the present invention, an elastic cloth 14 is installed between the strip plate 12 and the mounting plate 6. The elastic cloth 14 has several openings 16, and a suction fan 15 is installed in the openings 16. The suction end of the suction fan 15 is located on the side of the elastic cloth 14 near the multi-stage electric telescopic rod 11. The openings 16 on the elastic cloth 14 facilitate the installation of the suction fan 15 and facilitate the connection between the suction fan 15 and the elastic cloth 14.

[0034] As a technical optimization of the present invention, mounting strips 13 are installed on the opposite sides of the strip plate 12 and the mounting plate 6, and elastic cloth 14 is installed between the two mounting strips 13. The mounting strips 13 facilitate the installation of elastic cloth 14 between the strip plate 12 and the mounting plate 6.

[0035] As a technical optimization of the present invention, a motor 8 is installed on the side of the mounting plate 6 near the mounting disk 9. The output shaft of the motor 8 is connected to the mounting disk 9. The output shaft of the motor 8 can easily drive the mounting disk 9 to rotate, thereby causing the fixing plate 10 to rotate.

[0036] As a technical optimization of the present invention, a fixing rod 19 is installed on the side of the mounting plate 6 near the mounting disk 9, and a slider 18 is installed at the end of the fixing rod 19. An annular groove 17 is provided on the side of the mounting plate 6 near the mounting disk 9, and the slider 18 is slidably installed in the annular groove 17. Through the cooperation of the annular groove 17 and the slider 18, it can provide guidance when the mounting disk 9 rotates, and ensure the stability of the mounting disk 9 when rotating.

[0037] As a technical optimization of the present invention, the top of the electric cart 1 is equipped with a controller 3 and a buzzer alarm 4. The gas concentration monitoring probe 21 is electrically connected to the controller 3, and the controller 3 is electrically connected to the buzzer alarm 4. When the gas concentration monitoring probe 21 detects that the gas concentration in the air exceeds the standard, the gas concentration monitoring probe 21 transmits the signal to the controller 3, and the controller 3 can control the buzzer alarm 4 to sound an alarm. It can quickly alert the staff that the gas concentration in the air at this location in the mine exceeds the standard, and can quickly carry out audible and visual alarm processing.

[0038] As a technical optimization of the present invention, a reinforcing block 7 is installed at the end of the piston rod of the electric push rod 5. The reinforcing block 7 is installed at the bottom of the mounting plate 6, and the reinforcing block 7 can increase the connection strength between the end of the piston rod of the electric push rod 5 and the mounting plate 6.

[0039] As a technical optimization of the present invention, two counterweight boxes 2 are symmetrically installed on the top of the electric cart 1. The counterweight boxes 2 are filled with sand. The top of the counterweight box 2 has a feed port and the side of the counterweight box 2 has a discharge port. The electric push rod 5 is located between the two counterweight boxes 2. The counterweight boxes 2 can increase the counterweight of the electric cart 1 and ensure the stability of the electric cart 1 when moving.

[0040] As a technical optimization of the present invention, the mounting block 20 has a mounting groove on the side away from the multi-stage electric telescopic rod 11, and a mounting seat is installed in the mounting groove. The gas concentration monitoring probe 21 is installed on the mounting seat. The mounting seat facilitates the installation of the gas concentration monitoring probe 21, and the mounting groove facilitates the installation of the mounting seat on which the gas concentration monitoring probe 21 is installed.

[0041] When using this invention, if it is necessary to monitor the underground gas concentration, firstly, start the electric push rod 5. The piston rod of the electric push rod 5 pushes the mounting plate 6 upward until the mounting plate 6 is moved to the center of the mine shaft and then stops.

[0042] At this time, two multi-stage electric telescopic rods 11 are activated simultaneously. The piston rods of the multi-stage electric telescopic rods 11 push the strip plate 12 to move away from the fixed plate 10 until the distance between the two strip plates 12 is 20 centimeters smaller than the diameter of the mine tunnel and then stops.

[0043] When the strip plate 12 moves away from the fixed plate 10, its several mounting blocks 20 simultaneously move away from the fixed plate 10, and the distance between two adjacent mounting blocks 20 gradually increases, and the distance between any two adjacent mounting blocks 20 is equal. The elasticity of the spring 24 allows the several mounting blocks 20 to move away from the fixed plate 10 simultaneously. At the same time, the cooperation of the spring 24, the guide rod 23 and the sleeve 22 makes the distance between the several mounting blocks 20 equal, thereby unfolding the several mounting blocks 20, and thus unfolding the gas concentration monitoring probes 21 installed on the sides of the several mounting blocks 20, so that the several gas concentration monitoring probes 21 are unfolded in a uniformly distributed state, and the distance between each gas concentration monitoring probe 21 is equal.

[0044] At this time, the motor 8 is started. The output shaft of the motor 8 drives the mounting plate 9 to rotate. The rotation of the mounting plate 9 drives the fixing plate 10 to rotate. The fixing plate 10 drives the two multi-stage electric telescopic rods 11 to rotate. The piston rods of the multi-stage electric telescopic rods 11 drive the strip plate 12 to rotate, which in turn causes several mounting blocks 20 to rotate, which in turn causes several evenly distributed gas concentration monitoring probes 21 to rotate. During the rotation of several gas concentration monitoring probes 21, the gas concentration at that location in the mine can be monitored. By using several gas concentration monitoring probes 21 that are evenly distributed laterally and monitoring the gas concentration in the mine during the rotation of several gas concentration monitoring probes 21, the gas concentration at that location in the mine can be comprehensively monitored. Furthermore, the position of several gas concentration monitoring probes 21 rotates in real time, which can comprehensively monitor the gas concentration at that location in the mine, improving the comprehensiveness of gas concentration monitoring in the mine.

[0045] Furthermore, by moving the electric cart 1 within the mine shaft, the electric cart 1 can thoroughly and comprehensively monitor the gas concentration within the mine shaft.

[0046] Furthermore, when several gas concentration monitoring probes 21 monitor the gas concentration in the mine, the piston rod of the multi-stage electric telescopic rod 11 pushes the strip plate 12 to move away from the fixed plate 10. The strip plate 12 can pull the elastic cloth 14 to unfold. The unfolding of the elastic cloth 14 allows several suction fans 15 to be located behind several gas concentration monitoring probes 21. When the suction fans 15 are started, they can suck in the air in the mine, which in turn allows the air in the mine to flow towards the gas concentration monitoring probes 21. This facilitates the gas concentration monitoring probes 21 to quickly monitor the gas concentration in the air in the mine. The gas in the mine can flow towards the suction fans 15. When the gas flows towards the gas concentration monitoring probes 21, it passes through several gas concentration monitoring probes 21. The gas passing through these probes can be monitored, thereby monitoring the gas concentration in the air and ensuring the efficiency of gas concentration monitoring in the mine.

[0047] Furthermore, the multi-stage electric telescopic rod 11 is used to push the strip plate 12 away from the fixed plate 10, thereby causing several gas concentration monitoring probes 21 to unfold. The spacing between the two strip plates 12 can be adjusted according to the diameter of the mine shaft, which allows for comprehensive monitoring of gas concentration in mine shafts of different diameters.

[0048] After the gas concentration monitoring in the mine is completed, the multi-stage electric telescopic rod 11 is activated again. The piston rod of the multi-stage electric telescopic rod 11 drives the strip plate 12 to move closer to the fixed plate 10, thereby causing the two strip plates 12 to move closer to each other. This allows the several deployed gas concentration monitoring probes 21 to be retracted, reducing the space occupied. Furthermore, when the two strip plates 12 move closer to each other, they can also retract the deployed elastic cloth 14, thereby retracting the deployed suction fan 15. This prevents the elastic cloth 14 and the suction fan 15 from occupying too much space. When the device is not in use, the deployed gas concentration monitoring probes 21 and the elastic cloth 14 can be retracted to reduce the space occupied, making the device convenient and flexible to use.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
