Description

Technical Field

[0001] This utility model relates to the technical field of combustible gas detection equipment, and in particular to a combustible gas detection device. Background Technology

[0002] Combustible gas transportation typically uses pipelines. During pipeline construction, multiple pipe sections need to be connected, usually using flanges. These flanges typically incorporate sealing structures to prevent gas leakage at the joints. However, over time, the possibility of leakage still exists at these joints. Therefore, regular inspections are necessary to prevent gas leakage during transportation. Current technology generally uses handheld combustible gas detectors with probes. These detectors require manual, on-site inspection by personnel, often necessitating multiple people working together or sequential inspections, resulting in a large workload and low efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a combustible gas detection device, which solves the problem of low efficiency caused by the need for staff to hold the detector and conduct on-site testing.

[0004] According to an embodiment, a combustible gas detection device is provided, comprising an upper mounting cover and a lower mounting box that interlock, with a pair of through holes between them for a pipe to pass through. A mounting cylinder communicating with the inside and outside of the upper mounting cover is fixedly connected to the upper mounting cover, and a detection probe is disposed inside the mounting cylinder. An air inlet duct communicating with the inside and outside of the upper mounting cover is also fixedly connected to the upper mounting cover. The air inlet duct and the mounting cylinder are located on the upper mounting cover near the two through holes, respectively. An exhaust pipe communicating with the mounting cylinder is also provided, and the exhaust pipe is connected to an exhaust fan. Unlike existing technologies, this solution uses a method of fixing the detection probe at the connection point, avoiding the need for operators to go to the site. This reduces the overall workload and improves detection efficiency, solving the problem of low efficiency caused by the need for operators to hold the detector on-site in existing technologies.

[0005] Furthermore, a partition is fixedly connected inside the mounting cylinder. The partition has mounting holes and multiple connecting holes surrounding the mounting holes. The detection probe is snapped into the mounting holes and has a detection end located below the partition. The suction pipe is located above the partition.

[0006] Furthermore, a first cover plate is detachably connected to the top of the mounting cylinder, and the detection probe is also snapped into the cover plate and has a wiring terminal extending above the first cover plate.

[0007] Furthermore, multiple connecting holes are provided between the air inlet duct and the upper mounting cover, and the air inlet duct is also filled with filter media.

[0008] Furthermore, a second cover plate is detachably connected to the top of the air inlet duct, and an air inlet pipe that connects the inside and outside of the air inlet duct and is located above the filter medium is also fixedly connected to the air inlet duct.

[0009] Furthermore, a buffer ring is also provided between the perforation and the pipe.

[0010] Furthermore, the upper mounting cover includes a frame that engages with the lower mounting box and a frame cover that engages with the frame. A perforation is located between the frame and the lower mounting box, and the mounting cylinder and the air inlet cylinder are disposed on the frame cover.

[0011] Furthermore, the outer edge of the cover and the outer edge of the frame are respectively fixedly connected to a first connecting frame, and the two first connecting frames are detachably connected by a plurality of first connecting parts.

[0012] Furthermore, a second connecting frame is fixedly connected to the outer edge of the frame and the outer edge of the lower mounting box, and the two second connecting frames are detachably connected by a plurality of second connecting parts.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The pipe connection is located within the enclosed space of the upper mounting cover and the lower mounting box. The detection probe, installed inside the mounting cylinder fixed on the upper mounting cover, can detect combustible gases at the connection, eliminating the need for on-site operation by personnel. This reduces the overall workload and improves detection efficiency, solving the problem of low efficiency caused by the need for personnel to hold the detector on-site in existing technologies. At the same time, an exhaust fan is also installed to draw air outward, causing the gas in the enclosed space to flow outward and come into contact with the detection probe in a fluid manner. This can prevent combustible gas leaks from going undetected due to slow gas flow. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-3 As shown, this embodiment provides a combustible gas detection device, which includes an upper mounting cover 1 and a lower mounting box 2 that are fastened together, and a pair of through holes for a pipe 6 to pass through are provided between them. More specifically, the upper mounting cover 1 includes a frame 3 and a frame cover 4 that fastens to the frame 3. The frame 3 is fastened to the lower mounting box 2, and the two through holes are respectively enclosed by semi-circular structures provided on the frame 3 and the lower mounting box 2. When the two pipes 6 are connected, the lower mounting box 2 is placed below the connection end of the two pipes 6 so that the connection 5 ( The connected flange structure is located inside the lower mounting box 2, then the upper frame 3 is fastened, and then the frame cover 4 is fastened, so that the connection 5 of the two pipes 6 is set within the enclosed space surrounded by the upper mounting cover 1 and the lower mounting box 2; in a further embodiment, a mounting cylinder 7 communicating with the inside and outside of the enclosed space is also fixedly connected to the frame cover 4, and a detection probe 8 is installed inside the mounting cylinder 7. This detection probe 8 is used to detect combustible gas, just like in the prior art. If a combustible gas leak occurs, the combustible gas enters the enclosed space and then enters the mounting cylinder 7, where it will be detected. The detection probe 8 detects the gas leak. Furthermore, the detection probe 8 can use existing remote communication technology to transmit the detected signal to the backend, allowing the flammable gas leak to be detected by backend personnel in a timely manner. This eliminates the need for operators to conduct on-site inspections, reducing the overall workload and improving detection efficiency. This solves the problem of low efficiency caused by the need for personnel to carry out on-site inspections with handheld detectors in existing technologies. Furthermore, an air inlet duct 9 connecting the inside and outside of the enclosed space is fixedly connected to the frame cover 4. The air inlet duct 9 and the mounting cylinder 7 are located near the two perforations on the upper mounting cover 1, respectively. The mounting cylinder 7 is also equipped with an exhaust pipe 10 connected to it, and the exhaust pipe 10 is also connected to an exhaust fan. The exhaust fan can be run periodically, such as 2-5 minutes per week, forcing the gas in the enclosed space to flow into the mounting cylinder 7, increasing the probability of detection by the detection probe 8. It also prevents the flammable gas leak from going undetected due to slow gas flow. The exhaust fan can also be set to start periodically from the backend.

[0017] like Figure 1 , 4 As shown, a buffer ring 11 is also provided between the pipe 6 and the perforation. The buffer ring 11 is made of rubber. During installation, it is first put on the end of the pipe 6, then the pipe 6 is connected, and finally the upper mounting cover 1 and the lower mounting box 2 are installed. This can make the two perforations have better sealing. At the same time, this allows the perforation to be set slightly larger than the outer diameter of the pipe 6. After installation, the buffer ring 11 is elastically pressed against the perforation, making the installation smoother.

[0018] like Figure 1 , 3 As shown, in a further embodiment, the outer edge of the frame cover 4 and the outer edge of the frame body 3 are respectively fixedly connected to a first connecting frame 12. The two first connecting frames 12 are detachably connected by a plurality of first connecting pieces 13. Similarly, the outer edge of the frame body 3 and the outer edge of the lower mounting box 2 are respectively fixedly connected to a second connecting frame 14. The two second connecting frames 14 are detachably connected by a plurality of second connecting pieces 15. The first connecting pieces 13 and the second connecting pieces 15 can both be bolts, thus achieving a detachable connection. At the same time, elastic washers can be added between the first connecting frames 12 and between the second connecting frames 14. The elastic washers 24 are made of rubber, just like the buffer ring 11, and play a role in buffering and sealing. In particular, the elastic washers 24 between the second connecting frames 14 can also be an integral structure with the buffer ring 11, so that a better sealing effect can be achieved between the outer edge of the frame body 3 and the lower mounting box 2.

[0019] like Figure 1 , 2 As shown, in this scheme, a partition 16 is fixedly connected inside the mounting cylinder 7, and a first cover plate 20 can be detachably installed on the top. The partition 16 is provided with mounting holes and multiple connecting holes 17 surrounding the mounting holes. The detection probe 8 is snapped into the mounting holes and has a detection end 18 located below the partition 16. The detection probe 8 also has a wiring end 19 extending upward and passing through the first cover plate 20. The partition 16 and the first cover plate 20 provide a direct mounting base for the detection probe 8. Furthermore, the exhaust pipe 10 is located above the partition 16. When the exhaust fan is running, the gas in the enclosed space will enter the mounting cylinder 7 upward and contact the detection end 18 of the detection probe 8, and then pass through the connecting holes 17 and finally be drawn away from the exhaust pipe 10. The wiring end 19 of the detection probe 8 is located on the outside, which facilitates the connection to the communication module and power module, etc.

[0020] like Figure 1-3As shown, the air inlet duct 9 in this design allows external space to enter during the operation of the exhaust fan, ensuring that the gas within the enclosed space can be smoothly drawn into the installation duct 7. This also keeps the gas within the enclosed space in a flowing state, making it easier to detect flammable gas leaks. Furthermore, multiple connecting holes 17 are provided between the air inlet duct 9 and the frame cover 4, and an air inlet pipe 23 connecting the inside and outside of the air inlet duct 9 is fixedly connected to the upper end of the air inlet duct 9 to allow external air to enter. Even further, the air inlet duct 9 in this design is also equipped with a [missing information - likely a device or component] located below the air inlet pipe 23. The filter medium 21 intercepts and filters the incoming air to prevent impurities from being drawn into the enclosed space. The filter medium 21 can be granular or in other forms. The filter medium 21 does not pass through the connecting hole 17 located therein to prevent it from entering the enclosed space. At the same time, a second cover plate 22 can be detachably installed on the top of the air inlet duct 9 to facilitate the replacement and maintenance of the filter medium 21. Similar to the first cover plate 20, both the first cover plate 20 and the second cover plate 22 can be detachably connected by conventional connection methods, such as snap-fit ​​or bolt connection.

[0021] Finally, it should be noted that 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 preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
