Description

Technical Field

[0001] The present invention relates to the technical field of water content detection, and in particular to an online rapid detection device for the water content of crude oil. Background Art

[0002] Pre-treated crude oil removes impurities and, to ensure high fluidity, is heated to a high temperature, turning it into a fast-flowing liquid. During the transportation of liquid crude oil, an online rapid moisture content detector is used to monitor the moisture content in the crude oil in real time. This provides data on the moisture content and facilitates subsequent processing of the crude oil.

[0003] CN116008310A discloses a quick-install, online crude oil water content detection device and its installation method. The device features a microwave detection antenna and a PCB board connected to the microwave detection antenna, mounted on the side of a liquid-contacting structural component. The liquid-contacting structural component has a central hole in the center for crude oil flow in the pipeline. The central hole is slotted to expose a portion of the microwave detection antenna for detecting the crude oil water content. During installation, the sealing steel ring in the original clamp is replaced with the device's water content sensor, and an external explosion-proof meter is installed. While this device greatly simplifies installation of the water content detection device on the wellhead pipeline of an oil and gas well, it presents the following issues:

[0004] When the detection device detects the water content of crude oil liquid online, since the crude oil liquid flows in a vertical section at the pipeline position and has a large flow surface, and the water content sensor of the detection device is at a fixed position during detection, it is difficult to quickly detect the water content of a large area of ​​crude oil liquid at multiple precise points on the periphery, and it is difficult to simultaneously quickly detect the water content of the crude oil liquid at multiple precise points on the inner periphery. At the same time, it is difficult to know the location data of the specific detection point. The specific location of the water content needs to be analyzed later, resulting in a slow detection speed of the water content of the crude oil liquid at multiple points online, and thus a low detection efficiency of the water content of the crude oil liquid.

[0012] The beneficial effects of the present invention are:

[0013] 1. Utilizing the peripheral multi-point detection mechanism, the reduction motor drives the screw to rotate forward, the sleeve block drives the linkage column to move downward, the linkage column slides down along the inner wall of the sealing shaft ring, the guide frame drives the two sliding shafts to move downward, and at the same time the sliding shaft moves right on the inner wall of the guide frame, and the other sliding shaft moves left on the inner wall of the guide frame. The sliding shaft drives the peripheral water content sensor to slide right, and the other peripheral water content sensor to slide left. The sliding shaft also drives the peripheral water content sensor to move downward in a right circular arc, and the other peripheral water content sensor to move downward in a left circular arc.

The online detection speed of the water content of crude oil liquid is faster, thereby greatly improving the detection efficiency of the water content of crude oil liquid.

[0014] 2. A peripheral position linkage detection mechanism is adopted. When the guide rod moves downward in a rightward arc, the guide rod will drive the connecting bar to move downward in a rightward arc, and the first reading sensor will move downward in a rightward arc along the inner wall of the groove ring, and the first reading sensor will move downward in a rightward arc along the inner wall of the slide groove. The first reading sensor will move downward in a rightward arc along multiple peripheral identification barcodes, and the other first reading sensor will move downward in a leftward arc along other peripheral identification barcodes to read the height value and angle value of the peripheral identification barcode. In this way, the water content value sensed by the peripheral water content sensor corresponding to the peripheral identification barcode here is known, and multiple precise points on the periphery of a large area of ​​crude oil liquid can be achieved to quickly detect the water content. There is no need to analyze the specific position of the water content in the later stage, which greatly improves the detection efficiency of the water content of the crude oil liquid.

[0015] 3. Through the inner multi-point synchronous detection mechanism, when the guide frame moves downward, it will drive the connecting block to move downward, the connecting block will drive the transverse frame to move downward, the guide column will drive the second reading sensor to move downward, and at the same time, the guide column will drive the sleeve rod to move downward, the sliding limit ring will slide up and down on the S-shaped track, and the sleeve rod will move down in an S shape along the inner wall of the S-shaped track. When the guide frame drives the connecting block to move upward, the connecting block will drive the transverse frame to move upward, and the inner water content sensor will move upward along the S-shaped path. The lateral position will continue to be identified through the inner recognition barcode, and the distance sensing of the sensing block will be performed through the vertical distance sensor. The inner water content sensor can realize vertical reciprocating movement along the S-shaped path to detect the water content of the crude oil liquid. In this way, the water content detection of the inner multiple points can be quickly and accurately achieved. There is no need to analyze the specific location of the water content in the later stage. The location can be directly detected, which greatly improves the detection efficiency of the water content of the crude oil liquid.

[0016] The mutual influence of the above-mentioned multiple effects first enables the two peripheral water content sensors to quickly detect the water content of the crude oil liquid at multiple points on the periphery of the detection channel. At the same time, the first reading sensor will move down along the right-hand arc of multiple peripheral identification barcodes, while the other first reading sensor will move down along the left-hand arc of other peripheral identification barcodes. Finally, the inner water content sensor can move vertically back and forth along the S-shaped path to detect the water content of the crude oil liquid. In summary, it is possible to quickly detect the water content of multiple precise points on the periphery of a large area of ​​crude oil liquid, and it is possible to quickly detect the water content of multiple precise points on the inner periphery of the crude oil liquid simultaneously. The specific detection point location data can be accurately known, and there is no need to analyze the specific location of the water content in the later stage. The online crude oil liquid water content detection speed is faster, thereby greatly improving the detection efficiency of the crude oil liquid water content. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In this embodiment, as shown in the attached Figure 6-8 As shown, the peripheral position linkage detection mechanism includes a connecting bar 23 fixedly mounted on the top of the outer wall of the guide rod 11; a first reading sensor 24 is fixedly mounted on one side of the connecting bar 23, and a groove ring 26 is slidably connected to the outer wall of the first reading sensor 24. The inner wall of the groove ring 26 has a slide groove 28. A plurality of peripheral identification barcodes 25 are mounted on one side of the inner wall of the slide groove 28.

The plurality of peripheral identification barcodes 25 are evenly arranged circumferentially, and the vertical cross-section of the slide groove 28 is circular.

[0035] In this embodiment, as shown in the attached Figure 5-10As shown, the inner multi-point synchronous detection mechanism includes an S-shaped track 29 fixedly arranged on the inner wall of the circular track 12; the inner wall of the S-shaped track 29 is slidably connected to a sleeve rod 30, and both sides of the S-shaped track 29 are slidably connected to sliding limit rings 31, and the two sliding limit rings 31 are fixedly connected to the sleeve rod 30, and one end of the sleeve rod 30 is fixedly installed with an inner moisture content sensor 32; the inner wall of the sleeve rod 30 is slidably connected to a guide column 33, and one end of the guide column 33 is fixedly installed with a transverse frame 34, which is slidably connected to the sleeve rod 30, and the top of the outer wall of the sleeve rod 30 is fixedly connected to a second reading sensor 35; a plurality of inner identification bar codes 36 are provided above the second reading sensor 35, and the plurality of inner identification bar codes 36 are fixedly connected to the transverse frame 34; a connecting block 37 is fixedly installed between the transverse frame 34 and the guide frame 8. The two sliding limit rings 31 are symmetrically arranged about the S-shaped track 29 . The vertical cross-section of the sliding limit ring 31 is annular. The outer wall of the sleeve rod 30 and the inner wall of the S-shaped track 29 are both smooth surfaces.

[0036] The working principle of the online rapid detection device for the water content of crude oil of the present invention is as follows:

[0037] First, during docking installation, the present invention reads and writes angle values ​​and specific height values ​​on multiple peripheral identification barcodes 25, enabling specific positional information to be read and written on these multiple peripheral identification barcodes 25. Simultaneously, specific lateral values ​​are read and written on multiple internal identification barcodes 36. The docking plate 17 is bolted to the crude oil liquid pipeline. The crude oil is pressurized and heated during transportation, resulting in high fluidity. Another docking plate 17 is then docked to another crude oil liquid pipeline, enabling crude oil liquid transportation and flow through the detection channel 1.

[0038] Secondly, when the present invention performs peripheral multi-point detection, the reduction motor 5 is started through the wireless controller 15, the reduction motor 5 drives the screw 4 to rotate forward, the detection channel 1 supports the shell 2, and the detection channel 1 supports the support frame 3. The screw 4 drives the sleeve block 6 to move downward under the action of the thread transmission force, and the sleeve block 6 drives the linkage column 7 to move downward. The linkage column 7 slides down along the inner wall of the sealing collar 20. At the same time, the sealing collar 20 performs a sealing operation on the outer wall of the linkage column 7, and the linkage column 7 drives the guide frame 8 to move downward.

[0039] At the same time, the guide frame 8 drives the two sliding shafts 9 to move downward, and the sliding shaft 9 moves right on the inner wall of the guide frame 8, and the other sliding shaft 9 moves left on the inner wall of the guide frame 8, so that the sliding shaft 9 drives the two limit rings 13 to slide right on the guide frame 8. The sliding shaft 9 drives the peripheral water content sensor 10 to slide right, and the other peripheral water content sensor 10 to slide left. The sliding shaft 9 will drive the guide rod 11 to move downward in a rightward arc along the inner wall of the circular track 12. At the same time, the detection channel 1 supports the support plate 22, and the support plate 22 supports the support block 21. The support block 21 provides a stable support force for the circular track 12, and the other guide rod 11 will move downward in a leftward arc along the inner wall of the circular track 12. The guide rod 11 will drive the two slip rings 14 to move downward in a rightward arc. The sliding shaft 9 drives the peripheral water content sensor 10 to move downward in a rightward arc, and the other peripheral water content sensor 10 to move downward in a leftward arc. The two peripheral water content sensors 10 can realize rapid mobile detection of the water content of crude oil liquid at multiple points inside and outside the detection channel 1.

[0040] Then the sensing block 18 will approach the vertical distance sensor 19. When the distance value sensed by the vertical distance sensor 19 is the displacement value set by the wireless controller 15, the reduction motor 5 is started through the wireless controller 15. The reduction motor 5 drives the screw 4 to reverse, and the screw 4 drives the sleeve block 6 to move upward under the action of the thread transmission force. The sleeve block 6 drives the linkage column 7 to move the guide frame 8 upward, and the guide frame 8 drives the sliding shaft 9 to move upward. The sleeve block 6 drives the linkage column 7 to move the guide frame 8 upward, and the guide frame 8 drives the two sliding shafts 9 to move upward in an arc. The sliding shaft 9 drives the right guide rod 11 to move upward in an arc. The sliding shaft 9 drives the peripheral water content sensor 10 to move upward in a right circular arc. The other peripheral water content sensor 10 can also move upward in a left circular arc. The two peripheral water content sensors 10 can realize peripheral multi-point detection of crude oil liquid inside the detection channel 1.

[0041] At the same time, when the present invention performs linked peripheral position detection, when the guide rod 11 moves downward in a rightward arc, it drives the connecting bar 23 downward in a rightward arc. The connecting bar 23 drives the first reading sensor 24 downward in a rightward arc. The first reading sensor 24 moves downward in a rightward arc along the inner wall of the groove ring 26, and the first reading sensor 24 moves downward in a rightward arc along the inner wall of the slide groove 28. Simultaneously, the detection channel 1 supports the reinforcement block 27, which in turn supports the groove ring 26. The groove ring 26 can provide support for multiple peripheral identification barcodes 25. Simultaneously, the first reading sensor 24 moves downward in a rightward arc along the multiple peripheral identification barcodes 25, while another first reading sensor 24 moves downward in a leftward arc along another peripheral identification barcode 25. The first reading sensor 24 reads data from the multiple peripheral identification barcodes 25. When the first reading sensor 24 moves to the position of the peripheral identification barcode 25, the height value and the angle value of the peripheral identification barcode 25 are read, so that the water content value sensed by the peripheral water content sensor 10 corresponding to the peripheral identification barcode 25 here is known. In this way, the petroleum liquid water content values ​​corresponding to the specific positions of multiple peripheral points can be known, and the water content detection of multiple peripheral points can be quickly and accurately achieved.

[0042] At the same time, when the present invention performs synchronous detection of multiple points in the inner periphery, when the guide frame 8 moves downward, it will drive the connecting block 37 to move downward, the connecting block 37 will drive the transverse frame 34 to move downward, the transverse frame 34 will cause the guide column 33 to move downward, and the guide column 33 will drive the second reading sensor 35 to move downward. At the same time, the guide column 33 drives the sleeve rod 30 to move downward, and the sleeve rod 30 causes the two sliding limit rings 31 to move downward. The sliding limit ring 31 will slide up and down the S-shaped track 29. At the same time, the sleeve rod 30 moves downward in an S-shaped path along the inner wall of the S-shaped track 29, and the sleeve rod 30 slides horizontally along the outer wall of the guide column 33. The sleeve rod 30 will drive the inner moisture content sensor 32 to move downward along the S-shaped path. The sleeve rod 30 will also drive the second reading sensor 35 to move at the bottom of multiple inner identification barcodes 36. When the second reading sensor 35 approaches the inner identification barcode 36 at the specified position, it is recognized by the inner identification barcode 36 to identify the lateral position at this time. At the same time, the vertical distance sensor 19 performs distance sensing on the sensing block 18, and the vertical height position of the inner identification barcode 36 at this time can be known.

[0043] When the guide frame 8 drives the connecting block 37 to move upward, the connecting block 37 will drive the transverse frame 34 to move upward, and the transverse frame 34 causes the guide column 33 to move upward. The guide column 33 drives the sleeve rod 30 to move upward along the S-shaped path, and the inner water content sensor 32 moves upward along the S-shaped path. The sleeve rod 30 drives the second reading sensor 35 to continue to move the transverse position. In this way, the transverse position is continuously identified by the inner identification barcode 36, and the distance sensing of the sensing block 18 is performed by the vertical distance sensor 19. In this way, the inner water content sensor 32 can realize vertical reciprocating movement along the S-shaped path to detect the water content of the crude oil liquid, so that the water content detection of multiple points in the inner periphery can be quickly and accurately achieved.

[0044] Finally, when the present invention performs online testing, the crude oil liquid water content values ​​detected by the inner water content sensor 32 and the two outer water content sensors 10 are displayed on the display screen 16 of the wireless controller 15. At the same time, the wireless controller 15 can remotely transmit the data online to the background monitoring computer, allowing the background monitoring personnel to know the water content values ​​at multiple precise locations in real time online.
