Description

Technical Field

[0001] This application relates to the field of gas extraction technology, and in particular to a multi-parameter detection instrument for gas extraction pipelines. Background Technology

[0002] Methane gas is formed during the early stages of coal formation from ancient plant matter, as cellulose and organic matter are decomposed by anaerobic bacteria. Under high temperature and pressure, methane continues to be generated during coal formation due to physical and chemical processes. Methane is a colorless and odorless gas, but sometimes it can be smelled with an apple-like aroma due to the simultaneous release of aromatic hydrocarbon gases.

[0003] A search revealed that patent document CN216013357U discloses a gas extraction pipeline concentration detection device, comprising a gas pipeline, a connecting pipe connecting two gas pipelines (left and right), a fixed pipe connected to the top of the connecting pipe, and a mounting plate connected to the top of the fixed pipe. Insert shells are fixedly connected to both sides of the mounting plate, and housings are fixedly connected to both the front and rear sides of the insert shells. A first positioning spring is movably connected to the inner cavity of the housing. This device, through the coordinated use of the gas pipeline, mounting plate, connecting pipe, fixed pipe, housing, insert shell, insert plate, protective cover, fixed plate, positioning plug, mounting column, concentration detector, detection probe, second positioning spring, first positioning spring, positioning groove, and positioning ball, offers advantages such as convenient replacement and maintenance, improved disassembly efficiency, reduced workload for personnel, more comprehensive protection, and better protective effect.

[0004] In practical use, it has been found that existing multi-parameter detectors for gas extraction pipelines are only connected to the fixed pipe through a sealing sleeve during installation. As the outer side of the sealing sleeve will wear during installation, the sealing performance will be reduced, which will easily lead to gas leakage. Therefore, we propose a multi-parameter detector for gas extraction pipelines to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies where the connection between the gas extraction pipeline and the fixed pipe is only achieved through a sealing sleeve. This is because the outer side of the sealing sleeve will wear during installation, leading to reduced sealing performance and making it easy for gas to leak. Therefore, this application proposes a multi-parameter detection instrument for gas extraction pipelines.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a multi-parameter detection instrument for gas extraction pipelines, comprising a fixed pipe, a mounting base fixedly installed on the top of the fixed pipe, a connection hole provided on the mounting base, a detector provided above the mounting base, a connection base provided at the bottom of the detector, a detection probe provided at the bottom of the connection base, a sealing sleeve fixedly fitted on the outer side of the detection probe, the sealing sleeve being adapted to the connection hole; a clamping box fixedly installed on the top of the mounting base, the clamping box being located behind the connection hole, the clamping box being provided with a bidirectional mechanism and a fixing mechanism, two grooves provided on the mounting base, the connection hole being located between the two grooves, a cavity provided inside the mounting base, the cavity being located between the connection hole and the grooves, a piston mechanism being provided inside the cavity, an air bladder groove provided on the inner wall of the connection hole, a sealing mechanism being provided inside the air bladder groove, a seat hole provided on the front side of the clamping box, slots provided on both sides of the connection base, and a protective mechanism provided on the mounting base.

[0007] A further configuration of this application is as follows: the bidirectional mechanism includes a bidirectional screw and two screw seats. The same bidirectional screw is rotatably installed on the inner walls of both sides of the clamping box. The right end of the bidirectional screw passes through the right side of the clamping box. Two screw seats are threaded on the bidirectional screw. The screw seats are slidably connected to the seat holes. A knob is provided at the right end of the bidirectional screw.

[0008] By adopting the above technical solution and by setting up a bidirectional mechanism, the bidirectional screw can drive the two screw seats to move towards or away from each other, thereby achieving the purpose of driving the two clamping seats to move towards or away from each other.

[0009] A further configuration of this application is as follows: the fixing mechanism includes two clamping seats and two locking blocks. A clamping seat is fixedly installed on the front side of the screw seat, and a locking block is fixedly installed on the adjacent side of each of the two clamping seats. The locking blocks engage with corresponding locking slots, and a connecting mechanism is provided at the bottom of the clamping seats.

[0010] By adopting the above technical solution and by setting a fixing mechanism, when the two clamping seats move toward each other, they can drive the two locking blocks into the slots, thereby achieving the purpose of firmly connecting the detector and the mounting base.

[0012] By adopting the above technical solution and by setting up a connecting mechanism, the clamping seat can drive the piston rod to move synchronously through the first connecting plate and the second connecting plate.

[0013] A further configuration of this application is: the piston mechanism includes a piston plate and a piston rod, the piston plate is slidably installed in the cavity, the piston rod is fixedly installed on the outside of the piston plate, and the outer end of the piston rod is fixedly connected to the inner side of the second connecting plate.

[0014] By adopting the above technical solution and by setting up a piston mechanism, the piston rod can drive the piston plate to slide in the cavity, so as to realize the purpose of filling the gas in the cavity into the sealed airbag through the vent hole by the piston plate.

[0015] A further feature of this application is that the sealing mechanism includes a sealing airbag and a venting pipe, a sealing airbag is provided in the airbag groove, the same venting pipe is provided between the sealing airbag and the corresponding cavity, and the sealing airbag is adapted to the sealing sleeve.

[0017] A further feature of this application is that a common air hole is provided between the cavity and the groove, and the air hole is located below the piston rod.

[0018] By adopting the above technical solution and by setting air holes, the air pressure can be balanced through the air holes, thereby avoiding the normal operation of the piston mechanism due to excessive air pressure changes.

[0031] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] See Figures 1-5 This application provides a multi-parameter testing instrument for gas extraction pipelines, including a fixed pipe 1, a mounting base 2 fixedly installed on the top of the fixed pipe 1, a connection hole 201 on the mounting base 2, a detector 3 arranged above the mounting base 2, a connection seat 301 arranged at the bottom of the detector 3, a detection probe 303 arranged at the bottom of the connection seat 301, and a sealing sleeve 302 fixedly sleeved on the outside of the detection probe 303, so that the sealing sleeve 302 is adapted to the connection hole 201; a clamping box 4 is fixedly installed on the top of the mounting base 2, and the clamping box 4 is positioned... Behind the connecting hole 201, the clamping box 4 is provided with a bidirectional mechanism and a fixing mechanism. The mounting base 2 has two grooves 5, and the connecting hole 201 is located between the two grooves 5. The mounting base 2 has a cavity 6, which is located between the connecting hole 201 and the grooves 5. The cavity 6 is provided with a piston mechanism. The inner wall of the connecting hole 201 has an airbag groove 7, and the airbag groove 7 is provided with a sealing mechanism. The clamping box 4 has a seat hole on the front side. The connecting base 301 has slots 405 on both sides. The mounting base 2 is provided with a protective mechanism.

[0033] Specifically, the bidirectional mechanism includes a bidirectional screw 401 and two screw seats 402. The same bidirectional screw 401 is rotatably installed on the inner walls of both sides of the clamping box 4. The right end of the bidirectional screw 401 passes through the right side of the clamping box 4. Two screw seats 402 are threaded on the bidirectional screw 401. The screw seats 402 are slidably connected to the seat holes. A knob 9 is provided on the right end of the bidirectional screw 401.

[0034] Specifically, the fixing mechanism includes two clamping seats 403 and two locking blocks 404. The clamping seats 403 are fixedly installed on the front side of the screw seat 402. The locking blocks 404 are fixedly installed on the adjacent side of the two clamping seats 403. The locking blocks 404 are engaged with the corresponding locking slots 405. A connecting mechanism is provided at the bottom of the clamping seats 403.

[0035] Specifically, the connecting mechanism includes a first connecting plate 501 and a second connecting plate 502. The first connecting plate 501 is fixedly installed at the bottom of the clamping seat 403, and the second connecting plate 502 is fixedly installed on the outside of the first connecting plate 501. The second connecting plate 502 is slidably connected to the inner wall of the front side and the inner wall of the rear side of the groove 5.

[0036] Specifically, the piston mechanism includes a piston plate 601 and a piston rod 602. The piston plate 601 is slidably installed in the cavity 6, and the piston rod 602 is fixedly installed on the outside of the piston plate 601. The outer end of the piston rod 602 is fixedly connected to the inner side of the second connecting plate 502.

[0037] Specifically, the sealing mechanism includes a sealing airbag 701 and a venting pipe 702. The sealing airbag 701 is provided in the airbag groove 7. The same venting pipe 702 is provided between the sealing airbag 701 and the corresponding cavity 6. The sealing airbag 701 is adapted to the sealing sleeve 302.

[0038] Specifically, the cavity 6 and the groove 5 are provided with the same air hole, which is located below the piston rod 602.

[0039] Specifically, the protective mechanism includes a threaded ring seat 8 and a transparent cover 801. The threaded ring seat 8 is fixedly installed on the top of the mounting base 2. The threaded ring seat 8 is located outside the clamping box 4 and the connecting hole 201. The transparent cover 801 is threaded onto the threaded ring seat 8.

[0040] In this application, during use, the operator first accurately aligns the detection probe 303 with the sealing sleeve 302 below the bottom connecting seat 301 of the detector 3 with the connecting hole 201 on the mounting seat 2. This is the initial step of installation, ensuring that the detection probe 303 can smoothly enter the pipeline for parameter detection. Next, the operator rotates the bidirectional screw 401 located in the clamping box 4 by turning the knob 9. Due to the special thread structure of the bidirectional screw 401, when it rotates, the two screw seats 402 threaded with it will move closer to each other along the bidirectional screw 401 under the constraint of the seat hole on the front side of the clamping box 4. The movement of the screw seats 402 causes the clamping seat 403 fixed on its front side to move closer simultaneously, and the locking block 404 on the adjacent side of the clamping seat 403 will accurately engage in the locking groove 405 opened on both sides of the connecting seat 301. This achieves the purpose of firmly connecting the detector 3 with the mounting seat 2, and ensures that the detector 3 remains stable during operation, avoiding the impact of shaking or displacement on the accuracy of the detection results.

[0041] While the clamping seat 403 moves, its bottom connecting mechanism also plays an important role. The first connecting plate 501 and the second connecting plate 502 move together with the clamping seat 403, with the groove 5 of the second connecting plate 502 sliding. This pushes the piston rod 602 and the piston plate 601 to slide within the cavity 6. As the piston plate 601 slides, the gas in the cavity 6 is compressed and can be filled into the sealing airbag 701 through the vent pipe 702. This allows the sealing airbag 701 to expand. Since the sealing airbag 701 is compatible with the sealing sleeve 302, the expanded sealing airbag 701 can tightly fit the sealing sleeve 302. This greatly enhances the sealing performance between the detection probe 303 and the connecting hole 201, effectively preventing gas leakage, ensuring the stability of the detection environment, and thus improving the reliability of the detection results.

[0042] Meanwhile, the air hole between the cavity 6 and the groove 5 in the mounting base 2 also plays a crucial role. This air hole is located below the piston rod 602. During the sliding of the piston plate 601, it can balance the air pressure and prevent the piston mechanism from being affected by excessive air pressure changes, thus ensuring the smoothness of the entire installation process. After the instrument is installed and starts working, the protective mechanism begins to function. The threaded ring seat 8 is fixedly installed on the top of the mounting base 2 and is located outside the clamping box 4 and the connecting hole 201. The transparent cover 801 is installed on the threaded ring seat 8 by threads. The transparent cover 801 can provide physical protection for the detector 3, preventing it from being damaged by collisions with external objects, and can effectively block dust, water vapor and other pollutants, thus creating a relatively stable and clean working environment for the detector 3 and extending its service life.

[0043] When the detector 3 needs to be disassembled, maintained or replaced, the operator only needs to rotate the bidirectional screw 401 in the reverse direction using the knob 9. At this time, the components will operate in the reverse order of the installation process. The locking block 404 will disengage from the locking groove 405, the piston plate 601 will slide in the reverse direction, and the gas in the sealing airbag 701 will flow back to the cavity 6, thereby making it easy to remove the detector 3 and facilitating subsequent maintenance operations.
