Description

Technical Field

[0001] This utility model relates to the field of oil and gas production pipeline leakage detection technology, specifically to an oil and gas pipeline leakage detection device. Background Technology

[0002] Oil and gas pipelines are commonly used high-speed transport tools for long-distance oil and gas transportation. In actual oil and gas transportation processes, pipelines frequently experience leaks due to corrosion. Once a leak occurs, it can easily trigger fires and explosions, causing casualties and property damage. Furthermore, leaked oil and gas can cause serious environmental pollution, damaging soil, water sources, and ecosystems, while also leading to energy waste and economic losses.

[0003] Most existing oil and gas pipeline leak detection devices are complex in structure and expensive to manufacture, making them unaffordable for some small and medium-sized oil and gas pipeline companies. For example, patent document CN208687370U discloses an oil and gas pipeline leak detection device that includes a detection operating platform, a detection support plate, and a solar panel. The overall structure is complex and the cost is high. Moreover, it indirectly provides feedback on leak information by detecting gas in the strata near the oil and gas pipeline, rather than directly detecting leaks outside the pipeline.

[0004] Therefore, this patent application is filed. Utility Model Content

[0028] like Figures 1-7 As shown, an oil and gas pipeline leak detection device includes a first clamping block 4, a second clamping block 9, a sealing sleeve 8, a transmission channel, and a detection alarm 17. The first clamping block 4 and the second clamping block 9 are connected vertically, with the first clamping block 4 located above and the second clamping block 9 located below. The opposing surfaces of the first clamping block 4 and the second clamping block 9 are both arc-shaped surfaces, so that a sleeve hole is formed in the middle when the two clamping blocks are connected. The sealing sleeve 8 is installed in the sleeve hole, and a through hole is provided in the middle of the sealing sleeve 8 for the oil and gas pipeline to pass through. One end of the transmission channel passes through the side of the second clamping block 9 and is connected to the through hole. The other end of the transmission channel is equipped with the detection alarm 17.

[0029] In this embodiment, the sealing sleeve 8 is installed inside the sleeve hole of the second clamping block 9. A transmission channel is provided on the side of the second clamping block 9, which connects to the through hole in the middle of the sealing sleeve 8. When there is an oil or gas leak in the oil or gas pipeline, it can enter the transmission channel and be detected by the alarm 17, triggering an alarm to remind personnel to take timely measures. The entire detection device has a simple structure and low manufacturing cost. Moreover, in this device, the oil or gas pipeline can pass through the through hole, and when there is an oil or gas leak at that location, it can enter the transmission pipeline for monitoring, providing a more direct detection of the leak and thus providing direct feedback. The results are more accurate and superior to the current indirect feedback through detecting the formation.

[0030] Furthermore, the sealing sleeve 8 is made of an elastic material. For example, it can be made of rubber, silicone, or other materials. Because the sealing sleeve 8 is elastic, it can fit tightly against the oil and gas pipeline, ensuring a good sealing effect and preventing oil and gas leakage.

[0031] Furthermore, the inner wall of the sealing sleeve 8 is provided with an annular groove 7, the bottom surface of which is flush with or higher than the bottom surface of the transmission channel. The purpose of providing the annular groove 7 is to facilitate the collection of leaked oil and gas so that it enters the transmission channel more concentratedly.

[0032] Preferably, the first clamping block 4 and the second clamping block 9 are detachably fixedly connected, facilitating the installation and removal of the sealing sleeve 8. A mounting block 6 is provided on the second clamping block 9. The mounting block 6 and the second clamping block 9 can be integrally formed, and the length of the mounting block 6 is greater than the length of the second clamping block 9. The mounting block 6 has a positioning hole 5. The detection device can be secondary fixed at a suitable installation position using the mounting block 6 and the positioning hole 5. The aforementioned detachable fixed connection can be detachably fixed using the threaded rod 1 and positioning nuts. Two positioning nuts are provided: a first positioning nut 3 and a second positioning nut 2, used to press the sealing sleeve 8 tightly, ensuring a close fit with the oil and gas pipeline.

[0033] Example 2: Based on Embodiment 1, the transmission channel further includes a first connecting pipe 10, a connecting bend 11, and a second connecting pipe 12. The first connecting pipe 10 is connected through one side of the second clamping block 9. The connecting bend 11 is located between the first connecting pipe 10 and the second connecting pipe 12. The height of the second connecting pipe 12 is lower than the height of the first connecting pipe 10. A detection alarm 17 is installed on the second connecting pipe 12. A detection head 19 is provided at the top of the detection alarm 17. The detection head 19 can sensitively detect the presence of oil and gas. Once an oil and gas leak is detected, the detection alarm 17 will immediately sound an alarm, improving the detection sensitivity. An elastic sleeve 18 is provided at the end of the second connecting pipe 12. The elastic sleeve 18 is made of an elastic material such as elastic silicone. The elastic sleeve 18 is fitted over the detection head 19, serving to seal and protect the detection head 19.

[0034] Furthermore, a connecting frame is provided between the second connecting pipe 12 and the detection alarm 17 to provide a more stable connection between the detection alarm 17 and the second connecting pipe 12. The connecting frame includes a first support plate, a second support plate, and a connecting vertical plate. The first support plate and the second support plate are arranged opposite each other, and the first support plate and the second support plate are connected by the connecting vertical plate. The end of the second connecting pipe 12 passes through the upper first support plate and connects with the elastic sleeve 18. A hole 20 is provided on the second support plate, and the detection head 19 passes through the lower second support plate and is sleeved with the elastic sleeve 18.

[0035] Furthermore, a sealing sleeve 13 is provided on the outside of the second connecting pipe 12, and the sealing sleeve 13 is fixedly connected to the first support plate. The purpose is to form a stable seal at the junction of the second connecting pipe 12 and the first support plate, ensuring more accurate test results.

[0036] The first support plate is also provided with a plurality of first fixing holes 22 for connecting with the connecting vertical plate, and the sealing sleeve block 13 is also provided with a plurality of second fixing holes 21 for connecting with the first support plate.
