[0002] Oil extraction refers to the process of digging and extracting oil from areas with oil reserves. During the extraction process, oil and gas flow from the reservoir to the bottom of the well, rise from the bottom to the wellhead, and are then transported through pipelines. While existing oil pipelines reinforce their joints to prevent leaks and contamination, the effectiveness is limited. Therefore, we propose a pollution prevention device for oil extraction pipelines. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a pollution prevention device based on oil extraction pipelines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pollution prevention device based on an oil extraction pipeline, comprising a first oil pipeline and a second oil pipeline. The first and second oil pipelines are integrally formed with mating ends, one set of which is provided with a first sealing gasket. The first oil pipeline is integrally formed with a mating seat on its inner side, and a barrier conduit is integrally formed at one end of the mating seat. The second oil pipeline has a mating groove at one end. The outer periphery of the mating seat and the inner side of the mating groove are both provided with mutually engaging first locking threads. A sealing cover is fitted onto the outside of the second oil pipeline, and a sealing plate is fitted onto the outside of the first oil pipeline. A second sealing gasket is fixedly provided at one end of the sealing cover, and the outer periphery of the sealing plate and the inner side of the sealing cover are both provided with mutually engaging second locking threads.

[0005] Preferably, when the first oil pipeline and the second oil pipeline are assembled and connected, the docking seat on the inner side of the first oil pipeline and the docking groove inside the second oil pipeline are docked and sealed together. The first oil pipeline is threadedly connected to the first locking thread on the inner side of the docking groove through the first locking thread on the outer periphery of the docking seat. The barrier conduit at one end of the docking seat is located inside the second oil pipeline and is in an extended flow guiding state.

[0006] Preferably, the barrier conduit has an elliptical hollow structure and the opening of the barrier conduit gradually narrows towards the inside of the second oil pipeline, forming an angled barrier between the barrier conduit and the inside of the second oil pipeline.

[0007] Preferably, when the first oil pipeline and the second oil pipeline are assembled and connected, the mating ends of the first oil pipeline and the mating ends of the second oil pipeline are sealed and fitted together by a first sealing gasket.

[0008] Preferably, the sealing plate outside the first oil pipeline and the inner side of the sealing cover outside the second oil pipeline are connected by a second locking thread, and the sealing plate and the sealing cover are in a squeezed and sealed state by a second sealing gasket. The sealing plate and the sealing cover are in a secondary barrier sealing state outside the first oil pipeline and the second oil pipeline.

[0009] Preferably, the outer periphery of the sealing cover has a through groove communicating with the interior of the sealing cover, and a viewing window is provided on the inner side of the through groove. A pressure relief pipe is installed through the lower outer part of the sealing cover, and a valve plate is provided inside the pressure relief pipe. A connecting shaft is rotatably connected to the outer periphery of the pressure relief pipe through a connecting hole. One end of the connecting shaft is fixedly connected to the valve plate, and a sealing gasket is provided around the valve plate. A valve head is fixedly installed on the other end of the connecting shaft.

[0010] Preferably, when the valve plate is rotated to a horizontal angle by the valve head control connecting shaft, the valve plate is in a blocking state inside the pressure discharge pipe through the sealing gasket. When the valve plate is flipped to a vertical angle, the sealing cover is in a liquid guiding and discharge state through the pressure discharge pipe.

[0011] This utility model provides a pollution prevention device based on oil extraction pipelines. It has the following beneficial effects:

[0012] 1. This anti-pollution device based on an oil extraction pipeline, wherein when the first oil pipeline and the second oil pipeline are connected, the docking seat on the inner side of the first oil pipeline can be connected with the docking groove on the inner side of the second oil pipeline. At the same time, the barrier conduit at one end of the docking seat can be inserted into the interior of the second oil pipeline. The barrier conduit has an elliptical structure and is narrow at the port, so the barrier conduit and the inner side of the second oil pipeline can form an angle barrier. When the oil flows back into the interior of the second oil pipeline through the barrier conduit, the barrier conduit can initially block the oil, reducing the risk of leakage at the port of the traditional first oil pipeline and the second oil pipeline. The sealing plate and sealing cover on the outside of the first oil pipeline and the second oil pipeline can form a secondary sealing barrier after being sealed by the second locking thread. If the first oil pipeline and the second oil pipeline leak oil, it can be collected and sealed by the sealing cover and sealing plate to avoid direct leakage, thereby ensuring the sealing between the first oil pipeline and the second oil pipeline and improving the anti-pollution effect.

[0013] 2. This is a pollution prevention device based on oil extraction pipelines. The outer casing of the sealed cover is equipped with a pressure relief pipe. If the oil inside the first oil pipeline and the second oil pipeline leaks into the sealed cover, the valve plate inside the pressure relief pipe can be flipped to a vertical angle by controlling the rotation of the connecting shaft through the valve head. At this time, the oil collected inside the sealed cover can be discharged through the pressure relief pipe to avoid excessive pressure inside the sealed cover, thereby facilitating the discharge of oil pressure inside the sealed cover and preventing damage to the sealed cover.

A valve head 20 is fixedly installed on the other end of the connecting shaft 18.

[0025] Furthermore, when the first oil pipeline 1 and the second oil pipeline 2 are assembled and connected, the docking seat 5 on the inner side of the first oil pipeline 1 and the docking groove 7 inside the second oil pipeline 2 are docked and sealed together. The first oil pipeline 1 is threadedly connected to the first locking thread 8 on the outer side of the docking seat 5 and the first locking thread 8 on the inner side of the docking groove 7. The barrier conduit 6 at one end of the docking seat 5 is located inside the second oil pipeline 2 and is in an extended flow guiding state.

[0026] Furthermore, the barrier conduit 6 has an elliptical hollow structure and the opening of the barrier conduit 6 gradually narrows towards the inside of the second oil pipeline 2, forming an angled barrier between the barrier conduit 6 and the inside of the second oil pipeline 2.

[0027] Furthermore, when the first oil pipeline 1 and the second oil pipeline 2 are assembled and connected, the mating end 3 at the end of the first oil pipeline 1 and the mating end 3 at the end of the second oil pipeline 2 are sealed and fitted together by the first sealing gasket 4.

At the same time, the barrier conduit 6 at one end of the docking seat 5 can be inserted into the interior of the second oil pipeline 2. The barrier conduit 6 has an elliptical structure and a narrow port. In this way, the barrier conduit 6 and the inner side of the second oil pipeline 2 can form an angle barrier. When the oil flows back into the interior of the second oil pipeline 2 through the barrier conduit 6, the barrier conduit 6 can initially block the oil, reducing the risk of leakage at the port of the traditional first oil pipeline 1 and second oil pipeline 2. The sealing plate 10 and the sealing cover 9 on the outside of the first oil pipeline 1 and the second oil pipeline 2 can form a secondary sealing barrier after being connected and sealed by the second locking thread 12. If the first oil pipeline 1 and the second oil pipeline 2 leak oil, it can be collected and sealed by the sealing cover 9 and the sealing plate 10 to avoid direct leakage, thereby ensuring the sealing between the first oil pipeline 1 and the second oil pipeline 2 and improving the anti-pollution effect.
