Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pipeline inner wall cleaning equipment, and in particular to an oil pipeline dredging mechanism. Background Technology
[0002] Pipeline cleaning, where fluid propels a piston-like object to clean the inner wall of the pipeline, is widely used in the oil and gas industry. Current technology uses cup-type pipeline cleaning devices, but this method is limited and ineffective because it only cleans the pipe wall through the cup. During oil pipeline operation, the high flow rate makes it difficult for viscous substances to accumulate in the pipeline. However, when the valves are closed, the viscous substances in the oil gradually settle to the bottom as the flow rate decreases, resulting in a thick buildup of viscous substances on the inner wall of the pipeline, which affects its normal operation. Utility Model Content
[0003] Therefore, it is necessary to provide an oil pipeline dredging mechanism to address the above problems, which can clean areas with thick accumulation of viscous substances on the inner wall of the pipeline to ensure the normal operation of the pipeline.

[0019] like Figures 1-3 As shown,
[0020] As an optional embodiment,
[0021] An oil pipeline unblocking mechanism includes an unblocking pipeline 1, a scraper assembly 8 on the unblocking pipeline 1, the scraper assembly 8 including a first mounting plate 86 sleeved on the surface of the unblocking pipeline 1, the first mounting plate 86 being fixedly connected to the unblocking pipeline 1, the first mounting plate 86 having first sliding grooves 84 evenly spaced along its circumference, a first slider 83 slidably connected in the first sliding grooves 84, the first slider 83 having a first threaded hole 85, a fastening bolt threaded into the first threaded hole 85, a first mounting plate 82 installed at one end of the first slider 83, an arc-shaped scraper 81 in contact with the inner wall of the pipeline installed on the first mounting plate 82, and a counterweight 9 installed below the first mounting plate 86.
[0022] Specifically, to facilitate targeted treatment of specific areas on the inner wall of the oil pipeline, specifically the bottom area of the pipeline inner wall where sediment accumulates most, a special scraper assembly 8 is required for targeted treatment to improve the thoroughness of cleaning. Therefore, this application proposes a scraper assembly 8 for treating the bottom area of the inner wall of the oil pipeline. This assembly is placed inside the pipeline and moves forward with the liquid flow direction to clean the area it passes through. The first groove 84 on the side of the first mounting plate 86 is radially formed. This embodiment designs four first grooves 84, which are arranged in a circumferential array along the periphery of the first mounting plate 86. Each groove is slidably connected to a first slider 83. The first slider 83 slides in the first groove 84, thereby changing the position of the first mounting plate 82 connected to the end of the first slider 83. When the first mounting plate 82 is far from the first mounting plate... The central axis of plate 86 changes, thus adapting to clean pipes with different inner diameters. When the whole plate moves in the pipe, the arc-shaped scraper 81 connected to the first mounting plate 82 cleans the inner wall of the pipe. The four arc-shaped scrapers 81 can clean the four areas of the pipe, namely the top, bottom, left, and right. In addition, since the first slider 83 needs to slide and adjust its position in the first slide groove 84, and after adjusting its position, the first slider 83 needs to be fixed in the first slide groove 84, so the first slider 83 is designed with a first threaded hole 85. Subsequently, the fastening bolt passes through the first threaded hole 85 and abuts against the bottom of the first slide groove 84, pressing the first slider 83 tightly against the inner wall of the first slide groove 84. As the liquid flows, in order to prevent the whole plate from deflecting, a counterweight 9 is designed. Multiple counterweights 9 are placed below the first mounting plate 86 to ensure that the arc-shaped scraper 81 can remain in the corresponding area during the movement.
[0023] Based on Example 1, such as Figure 1 As shown:
[0024] The left and right ends of the unblocking pipe 1 are fixedly connected to first connecting cylinders 2. First rubber cups 3 are installed on the surfaces of the two first connecting cylinders 2. A second rubber cup 4 is fixedly connected to the surface of the first connecting cylinder 2 between the two first rubber cups 3. Each of the two first connecting cylinders 2 has two rubber cups, meaning each first connecting cylinder 2 has one first rubber cup 3 and one second rubber cup 4. Each rubber cup is fixedly connected to the corresponding connecting cylinder, allowing for cleaning of the inner wall of the pipe. The scraper assembly 8 is located between two adjacent rubber cups, propelling the dirt scraped by the scraper assembly 8 forward.
[0025] A hook 5 is provided at one end of the first connecting cylinder 2 along its central axis. The hook 5 is connected to the end face of the first connecting cylinder 2 through the first support bar 6. The hook 5 facilitates subsequent manual handling or suspension of the entire device.
[0026] like Figure 3 As shown, a cleaning assembly 7 for wiping loose dirt from the inner wall of an oil pipeline is installed on the unblocking pipe 1. The cleaning assembly 7 includes a second mounting plate 76 fitted onto the surface of the unblocking pipe 1, which is fixedly connected to the pipe 1. Second grooves 74 are evenly spaced along the circumference of the second mounting plate 76, and a second slider 73 is slidably connected within each groove. A second threaded hole 75 is formed on the second slider 73, and a fastening bolt is threaded into each threaded hole 75. A second mounting plate 72 is installed at one end of the second slider 73, and an arc-shaped brush plate 71 that contacts the inner wall of the pipe is mounted on the second mounting plate. During use, the second slider 73 can be moved along the mounting plate 76. The second slider 73 slides outward along its radial direction in the second slide groove 74, so that the arc-shaped brush plate 71 at the end of the second slider 73 contacts the pipe wall. At this time, the second slider 73 is then tightened into the second threaded hole 75 and abutted against the bottom of the second slide groove 74 by the fastening bolt, thus pressing the second slider 73 tightly against the wall of the second slide groove 74. The counterweight 9 is placed between the first mounting plate 86 and the second mounting plate 76. The two ends of the base of the counterweight 9 are respectively connected to the two opposite outer walls between the two mounting plates, so as to prevent the arc-shaped brush plate 71 and the arc-shaped scraper 81 from leaving the corresponding cleaning area during the movement in the pipe. It is worth noting that the number of counterweights 9 can be stacked, and multiple counterweights 9 can be fastened together.
[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
