Description

Technical Field

[0001] This utility model relates to the field of oil pipeline monitoring technology, specifically to a water content monitoring device for oil pipelines. Background Technology

[0002] Crude oil water content is a crucial parameter in the petrochemical industry. Crude oil extracted from oil fields generally contains a high water content, and its water content must be tested after extraction before refining. Currently, crude oil water content testing typically involves placing a water content detector into the oil pipeline for online monitoring.

[0003] In existing technologies, when detecting the water content in crude oil pipelines, the water content of the upper and lower layers of the medium in the pipeline is inconsistent due to gravity. It is impossible to accurately measure the actual water content of the medium inside the pipeline cavity using only a single extended probe. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an oil pipeline water content monitoring device, which solves the problem that existing technologies for detecting water content in large-diameter crude oil pipelines are prone to being affected by gravity, resulting in inaccurate overall water content testing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water content monitoring device for an oil pipeline includes a mounting flange and a water content detection probe. The mounting flange has multiple through mounting holes, and a compression fixing assembly is detachably mounted on each through mounting hole. The water content detection probe is detachably mounted on the compression fixing assembly, and the compression fixing assembly and the water content detection probe are installed in groups. The mounting flange has at least two groups, and the detection height of each water content detection probe in the pipeline is different. A sealing head is detachably mounted on an empty through mounting hole.

[0009] Preferably, the extrusion fixing assembly includes an extrusion sleeve and an extrusion nut sleeve. An internal thread is arranged in the through mounting hole. The extrusion sleeve is threadedly connected to the through mounting hole. The extrusion sleeve is threadedly connected to the outside of the extrusion sleeve. When fixing the moisture content detection probe, the extrusion sleeve is tightened and fixed to the moisture content detection probe penetrating through its middle by turning the extrusion nut sleeve.

[0010] Preferably, the compression sleeve includes at least two arc-shaped pieces, each arc-shaped piece having a compression threaded portion, which is threadedly connected to the compression nut sleeve. The lower part of the arc-shaped piece has a tapered portion, and the inner cavity of the compression nut sleeve has an inner groove that mates with the tapered portion. When the compression nut sleeve moves continuously downward, the inner groove continuously compresses the tapered portion, causing the tapered portion to continuously converge toward the centerline of the compression sleeve.

[0011] Preferably, the extrusion sleeve further includes a threaded sleeve, which is threadedly connected to the through mounting hole.

[0012] Preferably, a limiting ring is fixedly connected to the lower part of the tapered portion, and the threaded sleeve is fixedly disposed on the lower end face of the limiting ring. The diameter of the limiting ring is larger than the diameter of the through mounting hole.

[0013] (III) Beneficial Effects

[0014] This utility model has the following beneficial effects:

[0015] This pipeline water content monitoring equipment, by controlling the installation height of the water content detection probe and using a detachable clamping assembly, enables the detection of water content in different crude oil layers within the pipeline. By deploying a larger number of clamping assemblies and water content detection probes, it can provide water content detection for more layers of crude oil, resulting in subsequent processing of multiple sets of water content detection data that more closely reflects the actual water content.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This utility model provides a technical solution: a water content monitoring device for an oil pipeline, including a mounting flange 3 and a water content detection probe 4. The mounting flange 3 is provided with multiple through mounting holes, and a compression fixing component 5 is detachably installed on the through mounting holes. The water content detection probe 4 is detachably installed on the compression fixing component 5 through the through mounting holes. The compression fixing component 5 and the water content detection probe 4 are installed in groups. There are no less than two groups arranged on the mounting flange 3, and the detection height of each water content detection probe 4 in the pipeline is different. A sealing head 6 is detachably installed on the empty through mounting holes.

[0023] In practical applications, after understanding the parameters of pipeline 1 beforehand, the installation height of the water content detection probe 4 is controlled, and it is detachably installed using the compression fixing assembly 5, enabling water content detection for different crude oil layers along pipeline 1. Subsequently, the mounting flange 3 is fixed to the flange of the connecting pipe 2 on pipeline 1 using fasteners, thus completing the arrangement of the water content detection components for the entire pipeline 1. When further subdivision of the water content detection levels is required, the sealing head 6 can be removed, and more compression fixing assemblies 5 and water content detection probes 4 can be installed, providing water content detection for more levels of crude oil. This makes the results of subsequent processing of multiple sets of water content detection data more closely match the actual water content.

[0024] Reference Figure 3 and 4 As shown, in this embodiment, the compression fixing assembly 5 includes a compression sleeve 61 and a compression nut sleeve 62. An internal thread is arranged in the through mounting hole, and the compression sleeve 61 is threadedly connected to the through mounting hole. The compression sleeve 61 is also threadedly connected to the outside of the compression sleeve 62. When fixing the moisture content detection probe 4, the compression sleeve 61 is pressed tightly against and fixed to the moisture content detection probe 4 by rotating the compression nut sleeve 62. Through the configured compression sleeve 61 and compression nut sleeve 62, rotating the compression nut sleeve 62 moves it downwards, and the lower part of the compression nut sleeve 62 continuously presses against the compression sleeve 61, thereby pressing the compression sleeve 61 tightly against the moisture content detection probe 4, thus completing the fixing of the moisture content detection probe 4. The detection height of the moisture content detection probe 4 can also be adjusted as needed by loosening the compression nut sleeve 62.

[0025] To achieve the compression fixation of the compression sleeve 61 to the moisture content detection probe 4, refer to Figure 4 As shown, in this embodiment, the compression sleeve 61 includes at least two arc-shaped pieces 612. Each arc-shaped piece 612 has a compression thread 613, which is threadedly connected to the compression nut sleeve 62. A tapered portion 614 is provided at the lower part of the arc-shaped piece 612. The inner cavity of the compression nut sleeve 62 has an inner groove 63 that mates with the tapered portion 614. As the compression nut sleeve 62 moves downwards continuously, the inner groove 63 continuously compresses the tapered portion 614, causing the tapered portion 614 to continuously converge towards the centerline of the compression sleeve 61. Because the tapered portion 614 at the lower part of the arc-shaped piece 612 continuously compresses inwards, it stably compresses and fixes the moisture content detection probe 4.

[0026] To facilitate the detachable installation of the entire extrusion sleeve 61, refer to Figure 4 As shown, in this embodiment, the extrusion sleeve 61 also includes a threaded sleeve 611, which is threadedly connected to the through mounting hole.

[0027] Reference Figure 3 and 4 As shown, in this embodiment, a limiting ring 615 is fixedly connected to the lower part of the tapered portion 614, and a threaded sleeve 611 is fixedly disposed on the lower end face of the limiting ring 615. The diameter of the limiting ring 615 is larger than the diameter of the through mounting hole. The limiting ring 615, after being threadedly connected to the through mounting hole via the threaded sleeve 611, serves to limit the movement of the extrusion sleeve 61, ensuring that the entire extrusion sleeve 61 remains stable and does not rotate after the threaded sleeve 611 is subsequently tightened.
