Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a petrochemical gas detection instrument. Background Technology

[0002] The petrochemical industry is an important pillar of the national economy, but it generates various toxic and harmful gases during production. These gases not only threaten the health of production workers but also pollute the surrounding environment. Therefore, the detection of petrochemical gases is particularly important.

[0003] Traditional detection instruments are mostly fixedly installed on the wall near the oil and gas pipeline that needs to be detected. However, in some special cases, when there is no wall available for fixing near the oil and gas pipeline, the installation of the detection instrument is more difficult. Furthermore, the detection instrument installed on the wall is far away from the oil and gas pipeline, so it cannot detect gas leaks in a timely manner.

[0004] To address the aforementioned problems, this utility model document proposes a petrochemical gas detection instrument. Utility Model Content

[0005] This utility model provides a petrochemical gas detection instrument, which solves the shortcomings of the existing technology. Most traditional detection instruments are fixedly installed on the wall near the petrochemical gas pipeline to be detected. However, in some special cases, when there is no wall available for fixing near the petrochemical gas pipeline, the installation of the detection instrument is more difficult. In addition, the detection instrument installed on the wall is far away from the petrochemical gas pipeline, so it cannot detect gas leaks in time.

[0006] This utility model provides the following technical solution:

[0007] A petrochemical gas detection instrument includes a mounting plate, a groove is provided on one side of the mounting plate, a slider is slidably connected inside the groove, and a gas detector is provided on the outside of the mounting plate.

[0008] An adjustment mechanism is located outside the mounting plate and is used to adjust the operating status of the device.

[0009] The moving mechanism, located on one side of the mounting plate, is used to move the gas detector closer to the detection area.

[0010] In one possible design, the adjustment mechanism includes a turntable, a connecting block, and magnets. A groove is provided on one side of the connecting block, and one side of the turntable is rotatably connected to the inner wall of one side of the groove. An installation groove is provided on the other side of the connecting block. One side of one of the magnets is fixedly connected to the inner wall of one side of the installation groove, and one side of the other magnet is fixedly connected to the outer wall of the gas detector. One side of one magnet is magnetically connected to one side of the other magnet.

[0011] In one possible design, a connecting rod is fixedly connected to the outer wall of the connecting block, and a counterweight is fixedly connected to the other end of the connecting rod to help the gas detector maintain a vertical position.

[0012] In one possible design, the moving mechanism includes a threaded screw, a knob, a limiting bolt, an extension plate, a rotating shaft, a sleeve, and an electric push rod. One end of the threaded screw is rotatably connected to the inner wall of one side of the slide groove, and the other end of the threaded screw passes through the inner wall of one side of the slide groove and is fixedly connected to one side of the knob. The internal thread of the slider is connected to the outer wall of the threaded screw. A limiting hole is formed on one side of the mounting plate. The outer wall of the limiting bolt is threadedly connected to the inside of the limiting hole. One end of the limiting bolt passes through the inside of the limiting hole and abuts against the outer wall of the threaded screw. One side of one of the extension plates is fixedly connected to one side of the slider, and one side of the other extension plate is fixedly connected to one side of the turntable. The bottoms of the two rotating shafts are rotatably connected to the tops of the two extension plates, respectively. The interiors of the two sleeves are fixedly connected to the outer walls of the two rotating shafts, respectively. The output end of the electric push rod is fixedly connected to the outer wall of one of the sleeves, and the other end of the electric push rod is fixedly connected to the outer wall of the other sleeve.

[0013] In one possible design, a limiting plate is fixedly connected to one side of both the slider and the turntable, and a limiting screw is fixedly connected to the top of both rotating shafts. The other ends of the two limiting screws pass through the bottom of the two limiting plates and extend to the top of the two limiting plates, respectively. A limiting nut is threaded onto the outer wall of each of the two limiting screws, which is used to limit the rotation of the two rotating shafts.

[0014] In one possible design, multiple mounting blocks are fixedly connected to both sides of the mounting plate, and each of the mounting blocks has mounting holes inside, with mounting bolts threaded into the holes.

[0015] In this application, during use, the device is moved to the area to be detected. When there is a wall near the oil and gas pipeline in the detection area where the device can be installed, the mounting plate of the device is installed on the wall using the mounting bolts in multiple mounting blocks. Next, the threaded screw is rotated by rotating the knob, which in turn drives the slider to slide in the groove. This sliding mechanism allows the gas detector to be precisely adjusted horizontally. After the height of the gas detector is adjusted, the limit bolt is tightened to prevent the threaded screw from continuing to rotate. Then, the electric push rod can be activated. The electric push rod pushes the sleeve near the gas detector to move, thereby moving the gas detector away from the mounting plate, allowing it to extend towards the oil and gas pipeline. At the same time, the rotation of the two sleeves and two rotating shafts on the two extension plates allows the angle of the gas detector's extension direction to be easily adjusted. After the gas detector is close to the area of ​​the oil and gas pipeline to be detected, the knob is tightened... Tighten the two limit nuts to move them downwards until they are tightly fitted against the two limit plates, thus locking the two shafts and preventing them from rotating further. The gas detector can be quickly connected and disconnected via one magnet and another magnet inside the connecting block. The connecting rod and counterweight on the connecting block provide balance and stability. The weight of the counterweight helps the gas detector maintain a vertical position. When there is no wall available for the device to be installed in the installation area, the mounting plate of the device can be installed on the ground or roof of the installation area. Loosen the limit nut on the side closest to the gas detector to adjust the angle of the shaft. Once the gas detector is close to the area to be detected, return the limit nut to its original position. At this point, due to the gravity of the counterweight, the connecting block and the gas detector will rotate, thus keeping the gas detector in a vertical position and making it easier to access the area to be detected in various installation environments.

[0016] In this utility model, the petrochemical gas detection instrument, through the adjustment mechanism, can achieve the effect of installing gas detectors even when there is no suitable wall for installation, thereby enhancing the compatibility of the device with the installation site.

[0017] In this utility model, the petrochemical gas detection instrument can achieve the effect of stretching and adjusting the gas detector to be closer to the detection area through a moving mechanism, thereby making the detection effect of the device more accurate.

[0018] In this invention, the problem of not having a suitable wall for installation is solved by the design of the adjustment mechanism, which enhances the compatibility of the device with the installation site. At the same time, the flexible moving mechanism enables precise adjustment and stretching of the gas detector, effectively improving the detection accuracy. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-4 A detection instrument includes: a mounting plate 1, a groove is provided on one side of the mounting plate 1, and a slider 3 is slidably connected inside the groove, thereby providing a running basis for the moving mechanism of the device; a gas detector 19 is provided on the outside of the mounting plate 1; and multiple mounting blocks 2 are fixedly connected to both sides of the mounting plate 1 respectively. Each of the multiple mounting blocks 2 has a mounting hole inside, and a mounting bolt is threaded into the multiple mounting holes, thereby achieving the fixing effect of the device.

[0028] An adjustment mechanism, located outside the mounting plate 1, is used to adjust the operating state of the device. The adjustment mechanism includes a turntable 14, a connecting block 15, and magnets 16. One side of the connecting block 15 has a groove, and one side of the turntable 14 is rotatably connected to the inner wall of the groove. The other side of the connecting block 15 has a mounting groove. One side of one magnet 16 is fixedly connected to the inner wall of the mounting groove, and one side of the other magnet 16 is fixedly connected to the outer wall of the gas detector 19. One side of one magnet 16 is magnetically connected to one side of the other magnet 16, allowing the gas detector 19 to be quickly connected and disconnected from the other magnet 16 within the connecting block 15 via one magnet 16. The connecting rod 17 and the counterweight 18 on the upper part play a balancing and stabilizing role. The weight of the counterweight 18 helps the gas detector 19 to maintain a vertical state. When there is no wall in the installation area for the device to be installed, the mounting plate 1 of the device can be installed on the ground or roof of the installation area, and the limiting nut 12 on the side near the gas detector 19 can be loosened to adjust the angle of the rotating shaft 8. After the gas detector 19 is close to the area to be detected, the limiting nut 12 is returned to its original position. At this time, due to the gravity of the counterweight 18, the connecting block 15 and the gas detector 19 are driven to rotate, so that the gas detector 19 always maintains a vertical state, making it easier to approach the area to be detected in various installation environments.

[0029] A moving mechanism, located on one side of the mounting plate 1, is used to move the gas detector 19 closer to the detection area. The moving mechanism includes a threaded screw 4, a knob 5, a limiting bolt 6, an extension plate 7, a rotating shaft 8, a sleeve 9, and an electric push rod 13. One end of the threaded screw 4 is rotatably connected to the inner wall of one side of the slide groove, and the other end of the threaded screw 4 passes through the inner wall of one side of the slide groove and is fixedly connected to one side of the knob 5. The internal thread of the slider 3 is connected to the outer wall of the threaded screw 4. A limiting hole is provided on one side of the mounting plate 1, and the outer wall of the limiting bolt 6 is threaded into the inside of the limiting hole. One end of the limiting bolt 6 passes through the inside of the limiting hole and abuts against the outer wall of the threaded screw 4. One side of one extension plate 7 is fixedly connected to one side of the slider 3, and one side of the other extension plate 7 is fixedly connected to one side of the turntable 14. The bottoms of the two rotating shafts 8 are rotatably connected to the tops of the two extension plates 7, respectively. Two sleeves... The internal parts of sleeve 9 are fixedly connected to the outer walls of the two rotating shafts 8 respectively. The output end of the electric push rod 13 is fixedly connected to the outer wall of one of the sleeves 9, and the other end of the electric push rod 13 is fixedly connected to the outer wall of the other sleeve 9. Thus, the screw rod 4 can be rotated by rotating the knob 5, thereby driving the slider 3 to slide in the groove. This sliding mechanism allows the gas detector 19 to be precisely adjusted horizontally. After the height of the gas detector 19 is adjusted, the limit bolt 6 is tightened to prevent the screw rod 4 from continuing to rotate. Then the electric push rod 13 can be activated. The electric push rod 13 pushes the sleeve 9 on the side close to the gas detector 19 to move, thereby moving the gas detector 19 away from the mounting plate 1, so that it can extend towards the direction of the petroleum gas pipeline. At the same time, the rotation of the two sleeves 9 and the two rotating shafts 8 on the two extension plates 7 makes it easy to adjust the angle of the extension direction of the gas detector 19.

[0030] This application can be used in the field of petrochemical safety protection, or in other fields applicable to this application.

[0031] The specific model of the gas detector 19 is GT-GND20, and its structure and mechanism will not be described in detail here.

[0032] Example 2

[0033] Based on Example 1, the following improvements were made:

[0034] A petrochemical gas detection instrument, which is applied to the field of petrochemical safety protection, including:

[0035] A connecting rod 17 is fixedly connected to the outer wall of the connecting block 15, and a counterweight 18 is fixedly connected to the other end of the connecting rod 17 to help the gas detector 19 maintain a vertical state, so that the gas detector 19 can be kept perpendicular to the detection area, and can more accurately detect whether there is a leak of petroleum gas.

[0036] Limiting plates 10 are fixedly connected to one side of both slider 3 and turntable 14. Limiting screws 11 are fixedly connected to the top of both rotating shafts 8. The other ends of the two limiting screws 11 pass through the bottom of the two limiting plates 10 and extend to the top of the two limiting plates 10 respectively. Limiting nuts 12 are threadedly connected to the outer walls of the two limiting screws 11, which are used to limit the rotation of the two rotating shafts 8 respectively, thereby achieving locking after the device angle is adjusted, and further enhancing the stability of the device during use.

[0037] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric actuator 13 and the gas detector 19 are commonplace and are conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
