Description

Technical Field

[0001] This disclosure relates to the field of measurement technology, and in particular to a probe for a multi-principle water content analyzer. Background Technology

[0002] For a long time, measuring parameters such as liquid level, oil-water interface, and water cut in various crude oil tanks at oilfield production plants has been a technical challenge in industrial measurement. After crude oil is pumped from the well, it undergoes a series of processes, including heating, and is then sent to a settling tank for oil-water separation. After a certain period of settling, a clear interface between crude oil and water can be obtained. At this point, it is generally necessary to measure the amount of oil and water, as well as the water cut, etc.

[0003] Currently, when measuring oil and water in tanks, various instruments are typically installed on the tank to measure different data. These data are then combined to obtain individual values. For example, a magnetostrictive level gauge and a radio frequency admittance probe are installed on the tank to measure the oil and water content, respectively. This requires the use of multiple monitoring instruments, necessitating the creation of different installation spaces on the tank. This necessitates separate installation of the instruments and varying degrees of sealing, making the installation process complex. Furthermore, creating too many installation spaces may compromise the safety of the oil tank.

[0004] Therefore, there is an urgent need for a multi-principle water content analyzer probe that can integrate multiple data monitoring functions. Summary of the Invention

[0005] The purpose of this disclosure is to provide a multi-principle water content analyzer probe, which solves the problem that existing methods for monitoring data such as oil and water in crude oil tanks require the use of multiple different monitoring instruments.

[0006] To achieve the above objectives, a first aspect of this disclosure provides a multi-principle moisture analyzer probe, comprising:

[0007] A fixed housing, wherein a radio frequency admittance electronic unit and a magnetostrictive electronic unit are respectively disposed within the fixed housing;

[0008] The center rod has one end fixed inside the fixed housing and the other end extending outside the fixed housing;

[0009] An insulating sleeve is fixedly fitted onto the central rod;

[0010] The central rod has a hollow structure inside, and a magnetostrictive probe is installed inside the central rod. The end of the magnetostrictive probe is fixed to the fixed housing, and a magnetic float ball is slidably installed outside the central rod.

[0011] The fixed housing is also provided with a first electrical connector group and a second electrical connector group respectively.

[0012] The central rod is electrically connected to the radio frequency admittance electronic unit through the first electrical connector group to monitor the water content in the tank.

[0013] The magnetostrictive probe is electrically connected to the magnetostrictive electronic unit via the second electrical connector group to monitor the oil content in the tank.

[0014] In some embodiments, the multi-principle moisture analyzer probe further includes:

[0015] A fixed flange is attached to the insulating sleeve for connection to an external tank.

[0016] A ground connection fitting is sleeved onto the insulating pipe, and one end of the ground connection component is fixed to the fixed flange;

[0017] The ground connection fitting has an annular groove, and the end of the insulating sleeve extends to the annular groove and is integrally connected to an outer edge piece, which is snapped into the bottom of the annular groove.

[0018] A clamping member is provided inside the annular groove, which presses the outer edge portion to the bottom of the annular groove.

[0019] In some embodiments, the clamping member includes a clamping tube, the outer wall of which is provided with an external thread, the inner wall of which is provided with an internal thread, the clamping tube is sleeved onto the center rod and threaded into the annular groove of the ground end connecting tube, and the end of the clamping tube is pressed against the outer edge plate.

[0020] In some embodiments, the multi-principle moisture analyzer probe further includes a clamping ring pad, which is sleeved onto the end of the central rod and located between the clamping tube and the central rod;

[0021] The end of the clamping ring pad near the insulating sleeve is integrally connected to a clamping part, which is clamped to the outer edge plate; the end of the clamping tube abuts against the clamping part.

[0022] In some embodiments, at least a portion of the clamping fitting extends outside the ground connection pipe, and a lock nut is sleeved on the portion of the clamping fitting extending outside the ground connection pipe, with one side of the lock nut fixedly attached to the ground connection fitting.

[0023] In some embodiments, the multi-principle moisture analyzer probe further includes:

[0024] The support is fixed inside the fixed housing, one end of the central rod is fixed to the support, and the connection line between the central rod and the first electrical connector group can be fixed to the support;

[0025] An insulating base is connected to the support by bolts, and the magnetostrictive probe passes through the support and is fixed to the insulating base by a connecting fastener;

[0026] A shielding cover is attached to the insulating base, and the connection lines between the magnetostrictive probe and the second electrical connector group extend through the shielding cover.

[0031] By adopting the above technical solution, a magnetostrictive level gauge and a radio frequency admittance level gauge are rationally integrated. This allows for the measurement of the water interface position by utilizing the capacitance formed between the central rod and the water interface within the tank. The magnetostrictive probe, in conjunction with a floating magnetic buoy, measures the oil level within the tank. The amounts of oil and water can then be calculated separately. Subsequently, the water content can be calculated based on the ratio of oil content to water content. This probe can measure multiple data points, enabling various monitoring functions and multi-parameter testing, resulting in more comprehensive functionality. Furthermore, by placing the magnetostrictive probe inside the central rod and fitting the magnetic buoy onto it, the probe shares a single probe for monitoring, simplifying the structure, making the design more rational, and eliminating the need for repeated installations.

[0041] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0042] This disclosure provides a multi-principle water content analyzer probe, such as... Figures 1-4As shown, the multi-principle water content analyzer probe includes a fixed housing 1, a central rod 2, and an insulating sleeve 21. A radio frequency admittance electronic unit 12 and a magnetostrictive electronic unit 13 are fixedly installed inside the fixed housing 1. One end of the central rod 2 is fixed inside the fixed housing 1, and the other end extends outside the fixed housing 1. The insulating sleeve 21 is fixedly sleeved onto the central rod 2. The central rod 2 has a hollow internal structure. A magnetostrictive detection rod 23 is located at the center of the central rod 2, and its end is fixed inside the fixed housing 1. A magnetic float ball 26 is slidably installed outside the central rod 2. Additionally, a first electrical connector group 24 and a second electrical connector group 25 are fixedly installed inside the fixed housing 1. The central rod 2 is electrically connected to the radio frequency admittance electronic unit 12 through the first electrical connector group 24 to monitor the water content in the tank, while the magnetostrictive detection rod is electrically connected to the magnetostrictive electronic unit 13 through the second electrical connector group 25 to monitor the oil content in the tank.

[0043] This structural design integrates a magnetostrictive level gauge and a radio frequency admittance level gauge. The central rod 2, when energized, creates a capacitor between itself and the water interface within the tank. Changes in this capacitor value indicate the water interface position, allowing for the determination of the water content. This information is then transmitted to the radio frequency admittance electronic unit 12. Conversely, the magnetostrictive probe 23, when energized, generates a magnetic field within itself. This, in conjunction with a floating magnetic buoy 26, measures the oil level within the tank, determining the oil content, which is then transmitted to the magnetostrictive electronic unit 13. After obtaining the oil and water content, the water content can be calculated based on the oil-to-water ratio. This probe allows for the measurement of multiple data points, enabling various monitoring functions, multi-parameter testing, and more comprehensive functionality. In addition, in this probe, the magnetostrictive probe rod 23 is set inside the central rod 2, and the magnetic float ball 26 is sleeved on the central rod 2, so that they share a single probe rod for monitoring, making the structure simpler and the structure more reasonable, without the need for repeated installation.

[0044] It should be noted that the aforementioned insulating sleeve 21 needs to completely cover the lower end of the central rod 2 for electrical isolation, while the upper end only needs to cover the part extending into the fixed housing 1. Furthermore, the aforementioned magnetostrictive probe 23 uses the probe structure currently used in magnetostrictive level gauges, which consists of a waveguide wire at the center, covered by an insulating tube. This structure generates a ring-shaped magnetic field on the waveguide wire after a pulse current is input, allowing it to work in conjunction with the magnetic float 26. The central rod 2 is made of the same material used in current radio frequency admittance probes.

[0045] It should also be noted that the aforementioned radio frequency admittance electronic unit 12, magnetostrictive electronic unit 13, first electrical connector group 24, and second electrical connector group 25 can be fixed by connecting brackets. For example, connecting mounting brackets that match each structure can be welded and fixed in the fixed housing 1, so that the radio frequency admittance electronic unit 12, magnetostrictive electronic unit 13, first electrical connector group 24, and second electrical connector group 25 can be installed on different connecting mounting brackets to fix each structure relatively in the fixed housing 1.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the multi-principle water content analyzer probe also includes a fixed flange 3 and a ground connection pipe 4. The fixed flange 3 is connected to the insulating sleeve 21 for connection to an external tank, while the ground connection pipe 4 is sleeved onto the insulating sleeve, and one end of the ground connection pipe 4 is welded to the fixed flange 3. An annular groove 41 is provided inside the ground connection pipe 4. The end of the insulating sleeve 21 extends to the annular groove 41 and is integrally connected to an outer edge piece 211, which is snapped into the bottom of the annular groove 41. Furthermore, a clamping member is provided inside the annular groove 41, which presses the outer edge piece 211 against the bottom of the annular groove 41.

[0047] Thus, by setting the fixed flange 3, it is easy to connect this probe to the external tank. By setting it to the outer edge plate 211, the end of the insulating sleeve 21 can be stably pressed and fixed.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, the above-mentioned clamping component includes a clamping tube 5, which has an external thread on its outer wall and an internal thread on the inner wall of the annular groove 41. The clamping tube 5 is sleeved onto the center rod 2 and threaded into the annular groove 41 of the ground end connecting tube 4, and the end of the clamping tube 5 is clamped to the outer edge piece 211.

[0049] By using the clamping fitting 5, the outer edge piece 211 can be stably clamped to the bottom of the annular groove 41.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the multi-principle moisture analyzer probe also includes a clamping ring pad 51. The clamping ring pad 51 is sleeved on the upper end of the central rod 2 and located between the clamping tube 5 and the central rod 2. This allows the clamping ring pad 51 to be pressed onto the central rod 2 to protect the central rod 2, while also providing insulation between the clamping tube 5 and the central rod 2. It also enables the central rod 2 to be clamped and fixed, so that the central rod 2 is stably fixed at this position.

[0051] In addition, a clamping part 52 is integrally connected to one end of the clamping ring pad 51 near the insulating sleeve 21, and the clamping part 52 is clamped to the outer edge piece 211; the end of the clamping tube 5 abuts against the clamping part 52.

[0052] In this way, the clamping part 52 can form insulation between the center rod 2 and the ground end connecting pipe 4, and at the same time, the outer edge piece 211 can be locked by clamping the clamping part 52, which can prevent damage to the outer edge piece 211 and make it better clamped and fixed.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, at least a portion of the aforementioned clamping fitting 5 extends to the outside of the ground connection pipe, and the portion of the clamping fitting 5 extending to the outside of the ground connection pipe is threadedly connected to a lock nut 6, with one side of the lock nut 6 fixedly attached to the ground connection fitting 4.

[0054] The use of lock nut 6 can prevent the clamping fitting 5 from becoming loose and further tighten the clamping fitting 5.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the multi-principle water content analyzer probe also includes a support 7, an insulating base 71, and a shield 72. The support 7 is fixed inside the housing 1. One end of the central rod 2 is fixedly connected to the support 7, and the connection line between the central rod 2 and the first electrical connector group 24 can be fixed to the support 7. The insulating base 71 is fixedly connected to the support 7 by bolts. The magnetostrictive probe 23 passes through the support 7 and is fixed to the insulating base 71 by a connecting fastener 74. The shield 72 is fixedly connected to the insulating base 71, and the connection line between the magnetostrictive probe 23 and the second electrical connector group 25 extends through the shield 72.

[0056] Using the above structure, the upper end of the central rod 2 can be relatively fixed, while the magnetostrictive probe 23 extends out and connects to the insulating base 71. After the line extends through the shield 72, the electrical signal interference problems that occur during the wiring of the two units and subsequent use can be effectively avoided.

[0057] It should be noted that the aforementioned center rod 2 can be directly welded to the support 7, or it can be fixed to the support 7 through other detachable installation structures, as long as the upper end of the center rod 2 is fixed relative to the support 7. Additionally, an opening can be provided in the support 7 to allow the magnetostrictive probe 23 to pass through it. One end of the connecting fastener 74 is fixedly connected to the magnetostrictive probe 23, and the other end is fixedly connected to the insulating base 71. Alternatively, the connecting fastener 74 can also be fixed to the insulating base 71 using other snap-fit ​​connections, interference fits, or other methods, as long as they are mutually fixedly connected. Furthermore, the shielding cover 72 can be made of electromagnetic shielding material or other signal shielding materials to effectively prevent electrical signal interference during the wiring process between the two units.

[0058] like Figure 1 As shown, the probe of the multi-principle water content analyzer also includes an insulating gasket 73, which is disposed between the support 7 and the clamping tube 5.

[0059] The insulating gasket 73 can be used to create insulation between the clamping pipe 5 and the support 7, preventing the passage.

[0060] In some embodiments, such as Figure 1 As shown, the multi-principle water content analyzer probe also includes multiple support columns 62 and support components 61. One end of the support column 62 is welded and fixed to the fixed flange 3 for fixed installation of the radio frequency admittance electronic unit 12 and the magnetostrictive electronic unit 13.

[0061] Using this structure, the support member 62 can be fixed to the fixing flange 3. Then, the support member 62 can be used to install and fix the radio frequency admittance electronic unit 12 and the magnetostrictive electronic unit 13, providing these two units with installation space and ensuring stable fixation. Furthermore, the aforementioned first electrical connector group 24 and second electrical connector group 25 can also be fixedly installed on this support member 62 to facilitate connection between the first electrical connector group 24 and the second electrical connector group 25 and the radio frequency admittance electronic unit 12 and the magnetostrictive electronic unit 13, respectively.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the probe of the multi-principle water content analyzer also includes a limiting block 8, which has a mounting hole. The bottom of the insulating sleeve 21 is inserted into and fixed into the mounting hole.

[0063] By using the limiting block 8, the magnetic float 26 can be prevented from falling off the bottom of the insulating sleeve 21 during the use of this probe, thus creating a limit on it.

[0064] It should be noted that the aforementioned limiting block 8 can be directly fixed to the bottom of the insulating sleeve 21, or it can be connected using other detachable structures. For example, after the insulating sleeve 21 is inserted into the mounting hole, a locking bolt 81 can be set on one side of the limiting block 8, and it can pass through the limiting block 8 and extend into the insulating sleeve 21, thereby fixing the limiting block 8.

[0065] In some embodiments, such as Figure 1 As shown, the probe of the multi-principle water content analyzer also includes an upper cover 11, which is enclosed on the fixed housing 1.

[0066] By using the top cover 11, the fixed housing 1 can be completely enclosed, so as to provide good protection for the structure inside during use. The top cover 11 can be directly welded to the fixed housing 1, or it can be fixed by other means, such as installing the top cover 11 to the fixed housing 1 by means of threaded connection.

[0067] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0069] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
