Description

Technical Field

[0001] This utility model relates to the technical field of insertion-type gas parameter detectors, and in particular to an insertion-type gas parameter detector. Background Technology

[0002] Insertion-type gas parameter detectors are installed by inserting them into pipes or equipment. The probe or sensor is directly inserted into the gas pipe or container to monitor the gas concentration and other parameters in real time. Because it is in direct contact with the gas flow, it can monitor the gas state more accurately.

[0003] As shown in the reference case "An Insertion-Type Gas Parameter Detection Probe and Detector" (Announcement No. CN210603403U), a thermal flow meter is used. Among the two temperature sensors included in the thermal flow meter, one is used to output a temperature signal. By using a thermal flow meter, one of the temperature sensors of the thermal flow meter is used to directly detect the temperature of the gas in the gas pipeline and output a temperature signal, so that the flow detection device also has the function of measuring the temperature of the gas in the gas pipeline. This eliminates the need to set up a separate temperature sensor to detect the temperature of the gas in the gas pipeline, simplifying the structure of the insertion-type gas parameter detector.

[0004] When existing insertion-type gas detectors are installed and used, the diameter of gas pipelines can vary greatly. Since the insertion detection head of the existing detectors has a fixed structure, the detection head of the insertion-type gas detector cannot effectively detect the gas flow in pipelines of different diameters, resulting in unstable detection results.

[0005] Therefore, an insertion-type gas parameter detector is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an insertion-type gas parameter detector to solve the above-mentioned problems. This invention improves upon the existing insertion-type gas detectors, which, due to the large differences in the diameter of gas pipelines, have fixed insertion heads. This results in the insertion heads of existing detectors being unable to effectively detect gas flow in pipelines of different diameters, leading to unstable detection results.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: an insertion-type gas parameter detector, comprising: a gas detector, wherein a detection head is provided on one side of the gas detector; and an adjustment detection mechanism, wherein the adjustment detection mechanism is provided between the gas detector and the detection head for adjusting the position of the detection head inside the gas pipeline; wherein the adjustment detection mechanism includes an adjustment tube provided on one side of the gas detector, the detection head is provided between the adjustment tubes, an adjustment component for adjusting the position of the detection head is provided on one side of the adjustment tube, and a sealing component is provided on the outside of the adjustment tube. When the gas detector encounters gas pipelines of different diameters, the depth of the detection head inserted into the gas pipeline can be adjusted by the adjustment component, so that the detection head can be adapted to gas pipelines of different diameters, ensuring that the detection head is in a suitable detection position, making the gas detection effect more accurate. After the detection head is adjusted, the connection between the adjustment tube and the gas pipeline can be quickly sealed by the sealing component, so as to prevent gas leakage during the use of the gas detector.

[0008] Preferably, the adjustment assembly includes a drive ring slidably mounted on the outside of the adjustment pipe. The adjustment pipe has internal threads, and the adjustment pipe is threadedly connected to the outer wall of the detection head. When it is necessary to adjust the position of the detection head inside the gas pipeline, the drive ring can be rotated to synchronously drive the adjustment pipe to rotate, so that the adjustment pipe and the detection head perform threaded movement, thereby adjusting the position of the detection head inside the gas pipeline and ensuring that the detection head is in the correct detection position in gas pipelines of different diameters.

[0009] Preferably, the adjustment assembly further includes a fixing ring fixedly installed at the bottom of the gas detector. The bottom of the fixing ring has a slot, and the driving ring is located on one side of the slot and engages with the slot. After the driving ring is adjusted, the driving ring can be moved upward and engaged with the slot to fix it, thereby simultaneously fixing the adjustment tube.

[0010] Preferably, a positioning ring is fixedly installed on the surface of the adjusting tube. The positioning ring is located at the bottom of the adjusting tube. A spring is fixedly connected between the positioning ring and the adjusting tube. When the driving ring moves down, it synchronously compresses the spring, causing the spring to deform. When the driving ring engages with the slot, the spring synchronously resets and presses against the driving ring, making it less likely to loosen or shift accidentally.

[0011] Preferably, a protective sleeve is fixedly installed on the outer side of the positioning ring, and the other end of the protective sleeve is fixedly connected to the bottom of the adjusting tube. The spring is located inside the protective sleeve, and the protective sleeve effectively protects the spring from pollution and damage from the external environment.

[0012] Preferably, the sealing assembly includes a movable block slidably mounted on the surface of the regulating pipe. A rubber sleeve is fixedly connected to the bottom of the movable block. The movable block has an internal hollow structure, and the rubber sleeve is connected to the interior of the movable block. A valve core is fixedly connected to one side of the movable block. When it is necessary to seal between the regulating pipe of the gas detector and the gas pipeline, the movable block can be moved to move the rubber sleeve to the connection between the regulating pipe and the gas pipeline. Gas is injected through the valve core, and the rubber sleeve expands and tightly contacts the interface between the gas pipeline and the regulating pipe, thereby effectively preventing gas leakage.

[0013] Preferably, the sealing assembly further includes a plurality of positioning sleeves fixedly installed inside the movable block and the rubber sleeve. The plurality of positioning sleeves are all connected to the interior of the movable block and the rubber sleeve, and the plurality of positioning sleeves are in contact with the surface of the regulating tube. When gas is injected, the plurality of positioning sleeves expand and deform proportionally, and the plurality of positioning sleeves abut against the outer wall of the regulating tube to abut and fix the movable block and the regulating tube, effectively preventing the movable block from loosening or shifting during use.

[0014] The beneficial effects of this utility model are: When encountering gas pipelines of different diameters, the gas detector can adjust the depth of the detection head inside the gas pipeline through the adjustment component, so that the detection head can be adapted to gas pipelines of different diameters, ensuring that the detection head is in the appropriate detection position, making the gas detection effect more accurate. After the detection head is adjusted, the connection between the adjustment pipe and the gas pipeline can be quickly sealed through the sealing component to prevent gas leakage during the use of the gas detector. When it is necessary to seal the regulating pipe of the gas detector with the gas pipeline, the movable block can be moved to move the rubber sleeve to the connection between the regulating pipe and the gas pipeline. Gas is injected through the valve core, and the rubber sleeve expands and makes tight contact with the interface between the gas pipeline and the regulating pipe, thereby effectively preventing gas leakage.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In practical implementation: such as Figure 1-4 As shown, an insertion-type gas parameter detector includes: a gas detector 1, with a detection head 2 disposed on one side of the gas detector 1; and an adjustment detection mechanism 3, which is disposed between the gas detector 1 and the detection head 2 for adjusting the position of the detection head 2 within the gas pipeline. The adjustment detection mechanism 3 includes an adjustment tube 31 disposed on one side of the gas detector 1, the detection head 2 disposed between the adjustment tubes 31, an adjustment component 32 for adjusting the position of the detection head 2 disposed on one side of the adjustment tubes 31, and a sealing component 33 disposed on the outer side of the adjustment tubes 31. When the gas detector 1 is in use, the detection head 2 of the gas detector 1 can be inserted into the gas pipeline for real-time gas detection. When encountering gas pipelines of different diameters, the depth of the detection head 2 inserted into the gas pipeline can be adjusted by adjusting component 32, so that the detection head 2 can be adapted to gas pipelines of different diameters, ensuring that the detection head 2 is in the appropriate detection position, making the gas detection effect more accurate. After the detection head 2 is adjusted, the connection between the adjusting pipe 31 and the gas pipeline can be quickly sealed by sealing component 33, so as to prevent gas leakage during the use of gas detector 1.

[0019] Specifically, when technicians need to insert the gas detector 1 into a gas pipe with a diameter of 100mm, they can precisely control the insertion depth of the detection head 2 by adjusting the component 32 to ensure that the detection head 2 is in the optimal detection position. For gas pipes with diameters of 150mm to 200mm, the inspectors can also make corresponding adjustments by adjusting the component 32 to ensure that the detection head 2 is compatible with gas pipes of different diameters and has the appropriate depth, so as to accurately monitor the gas concentration.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the adjusting assembly 32 includes a drive ring 321 slidably mounted on the outside of the adjusting pipe 31. The adjusting pipe 31 has internal threads, and the adjusting pipe 31 is threadedly connected to the outer wall of the detection head 2. The top end of the detection head 2 is slidably connected to the bottom of the fixing ring 322. When it is necessary to adjust the position of the detection head 2 inside the gas pipeline, the drive ring 321 can be rotated to synchronously drive the adjusting pipe 31 to rotate, causing the adjusting pipe 31 and the detection head 2 to perform threaded movement, thereby adjusting the position of the detection head 2 inside the gas pipeline. The position is adjusted to ensure that the detection head 2 is in the correct detection position in gas pipes of different diameters. The adjustment assembly 32 also includes a fixing ring 322 fixedly installed at the bottom of the gas detector 1. The bottom of the fixing ring 322 has a slot 323. The drive ring 321 is located on one side of the slot 323 and is engaged with the slot 323. After the drive ring 321 is adjusted, it can be moved up to engage and fix the drive ring 321 with the slot 323, thereby simultaneously fixing the adjustment pipe 31.

[0021] A positioning ring 324 is fixedly installed on the surface of the regulating tube 31. The positioning ring 324 is located at the bottom of the regulating tube 31. A spring 325 is fixedly connected between the positioning ring 324 and the regulating tube 31. When the driving ring 321 moves down, it simultaneously compresses the spring 325, causing the spring 325 to deform. When the driving ring 321 engages with the slot 323, the spring 325 simultaneously resets and presses against the driving ring 321, making it less likely to loosen or shift accidentally. A protective sleeve 326 is fixedly installed on the outside of the positioning ring 324. The other end of the protective sleeve 326 is fixedly connected to the bottom of the regulating tube 31. The spring 325 is located inside the protective sleeve 326. The protective sleeve 326 effectively protects the spring 325 from pollution and damage from the external environment.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the sealing assembly 33 includes a movable block 331 slidably mounted on the surface of the regulating pipe 31. A rubber sleeve 332 is fixedly connected to the bottom of the movable block 331. The movable block 331 has an internal hollow structure, and the rubber sleeve 332 is connected to the interior of the movable block 331. A valve core 333 is fixedly connected to one side of the movable block 331. When it is necessary to seal the connection between the regulating pipe 31 of the gas detector 1 and the gas pipeline, the movable block 331 can be moved to move the rubber sleeve 332 to the connection point between the regulating pipe 31 and the gas pipeline. Gas is injected through the valve core 333, and the rubber sleeve 332 expands and makes tight contact with the gas pipeline. The interface between the regulating pipes 31 effectively prevents gas leakage. The sealing assembly 33 also includes multiple positioning sleeves 334 fixedly installed inside the movable block 331 and the rubber sleeve 332. The multiple positioning sleeves 334 are all connected to the inside of the movable block 331 and the rubber sleeve 332. The multiple positioning sleeves 334 are all in contact with the surface of the regulating pipe 31. When gas is injected, the multiple positioning sleeves 334 expand and deform proportionally, and the multiple positioning sleeves 334 abut against the outer wall of the regulating pipe 31 to abut and fix the movable block 331 and the regulating pipe 31, effectively preventing the movable block 331 from loosening or shifting during use.

[0023] In use, when it is necessary to adjust the position of the detection head 2 inside the gas pipeline, the drive ring 321 can be rotated to synchronously drive the adjusting tube 31 to rotate, causing the adjusting tube 31 to move threadedly with the detection head 2, thereby adjusting the position of the detection head 2 inside the gas pipeline. When the drive ring 321 moves downward, it simultaneously compresses the spring 325, causing the spring 325 to deform. When the drive ring 321 engages with the slot 323, the spring 325 synchronously resets to press against the drive ring 321, preventing accidental loosening or displacement. This invention is suitable for adjusting the gas detector. When sealing the regulating pipe 31 with the gas pipeline, the movable block 331 can be moved to move the rubber sleeve 332 to the connection between the regulating pipe 31 and the gas pipeline. Gas is injected through the valve core 333, and the rubber sleeve 332 expands and tightly contacts the interface between the gas pipeline and the regulating pipe 31, thereby effectively preventing gas leakage. When the gas is injected, multiple positioning sleeves 334 expand and deform proportionally, and multiple positioning sleeves 334 abut against the outer wall of the regulating pipe 31 to abut and fix the movable block 331 against the regulating pipe 31, effectively preventing the movable block 331 from loosening or shifting during use.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
