Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and more specifically, to a dredging device for oilfield gas transmission pipelines. Background Technology

[0002] The medium produced from oil and gas wells contains natural gas, oil, water, etc. Although it is separated by surface separation equipment, due to certain defects in the selection of separation equipment, medium characteristics, and some human operation, the natural gas after separation often contains a small amount of water and other impurities, which can lead to blockages in the pipelines transporting natural gas.

[0003] A search revealed Chinese patent application number 202323011432.6, which discloses a gas pipeline unblocking device for a gas collection station. The device includes a housing, with a motor fixedly installed inside. A rotating shaft is fixedly connected to the rotating end of the motor, and a connecting seat is fixedly connected to the front end of the rotating shaft. Drive frames are symmetrically arranged at the top and bottom of the connecting seat, and a scraper is fixedly mounted on each drive frame. A cleaning brush is fixedly mounted on the drive frame behind the scraper. This invention uses a worm gear to drive a worm wheel and a turntable to rotate together. Through the cooperation of an arc-shaped sliding groove and a connecting sliding column, it synchronously drives three support frames to move outward, causing the rollers to contact the inner wall of the gas pipeline. This supports the rotating shaft, ensuring it is coaxial with the gas pipeline and preventing damage to the scraper due to shaft tilting. Rotating a lead screw allows the two drive frames to move synchronously closer or further away, enabling the cleaning of gas pipelines of different diameters and enhancing its practicality. However, the aforementioned patents have the following shortcomings: when using this device, operators need to manually adjust the positions of the rollers and scrapers according to the actual diameter of the pipe to be dredged, and the process of adjusting the rollers and scrapers separately is cumbersome and consumes a lot of preparation time. Therefore, this utility model proposes a new solution. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figures 1-5 As shown, this embodiment proposes an oilfield gas pipeline dredging device, including an installation pipe 1 and a cable 11. A protective layer 10 is provided on the outside of the cable 11. The device also includes: multiple first supports 2, which are annularly hinged to the outer wall of the installation pipe 1. A first adjusting sleeve 4, which is slidably connected to the installation pipe 1, is hinged to each first support 2. Two symmetrically arranged rollers 12 are rotatably mounted on each first support 2. Multiple second supports 3, which are annularly hinged to the outer wall of the installation pipe 1 and located on one side of the first supports 2. A scraper 7 and a cleaning brush 8 are mounted on the top of each second support 3. A second adjusting sleeve 5, which is slidably mounted on the outside of the installation pipe 1, is hinged to one end of each second support 3. A connector 6, which is rotatably mounted on the end of the installation pipe 1, is hinged to the other end of each second support 3. A first motor 9, which is fixedly installed inside the installation pipe 1, has its output end connected to the connector 6. An electric telescopic rod 14, which is fixedly installed inside the installation pipe 1 and located on one side of the first motor 9, has an adjusting frame fixedly connected to its moving end, which cooperates with the first adjusting sleeve 4 and the second adjusting sleeve 5. With the configuration of the first bracket 2, the second bracket 3, and the electric telescopic rod 14, the electric telescopic rod 14 can slide the first adjusting sleeve 4 and the second adjusting sleeve 5 via the adjusting frame during use. This, in conjunction with the first bracket 2 and the second bracket 3, adjusts the positions of the roller 12, the scraper 7, and the cleaning brush 8, making it suitable for pipes of different diameters without the need for manual adjustment. The adjusting frame, the first adjusting sleeve 4, and the second adjusting sleeve 5 allow the adjusting frame to slide synchronously during use, thereby simultaneously adjusting the opening or closing range of the first bracket 2 and the second bracket 3. This allows for simultaneous adjustment of the positions of the roller 12, the scraper 7, and the cleaning brush 8, eliminating the need for separate adjustments and effectively shortening preparation time and improving unblocking efficiency. The first motor 9, via the connector 6, drives the second bracket 3 to rotate during use, thereby rotating the scraper 7 and the cleaning brush 8 mounted on the second bracket 3 to clean and unclog the blockages on the inner wall of the pipe.

[0016] like Figure 2As shown, in a preferred embodiment, based on the above method, the adjusting frame further includes a first slider 16 and a second slider 17 slidably installed inside the mounting tube 1. The first slider 16 and the second slider 17 are fixedly connected by a crossbar 15. Two first connecting plates 18, which are fixedly connected to the first adjusting sleeve 4, are symmetrically installed on the outer wall of the first slider 16. Two second connecting plates 19, which cooperate with the second adjusting sleeve 5, are symmetrically installed on the outer wall of the second slider 17. It should be noted that, in use, the first connecting plates 18 facilitate the connection between the first slider 16 and the inner wall of the first adjusting sleeve 4, and the second connecting plates 19 facilitate the movement of the second adjusting sleeve 5 by cooperating with the second slider 17.

[0017] like Figure 2 As shown, in a preferred embodiment, based on the above method, the side wall of the mounting tube 1 is further provided with a sliding groove 20 that cooperates with the first connecting plate 18 and the second connecting plate 19, and the inner wall of the second adjusting sleeve 5 is provided with an annular limiting groove 22 that cooperates with the second connecting plate 19. It should be noted that the sliding groove 20 allows the first connecting plate 18 and the second connecting plate 19 to slide, and the limiting groove 22 limits the position of the second connecting plate 19, making it easier for the second connecting plate 19 to cooperate with the second slider 17 to drive the second adjusting sleeve 5 to move. At the same time, the annular limiting groove 22 can also prevent the second connecting plate 19 from affecting the second adjusting sleeve 5 to rotate with the second bracket 3.

[0018] like Figure 1 , Figure 2 and Figure 4As shown, in a preferred embodiment, based on the above method, the first bracket 2 further includes a first mounting rod 201. A first connecting rod 202 and a second connecting rod 203 are hinged to the side wall of the first mounting rod 201. The ends of the first connecting rod 202 and the second connecting rod 203 away from the first mounting rod 201 are both hinged to the outer wall of the mounting tube 1. An adjusting rod 204 is hinged to the side wall of the second connecting rod 203. The end of the adjusting rod 204 away from the second connecting rod 203 is hinged to the first adjusting sleeve 4. A second motor 13 for driving the roller 12 to rotate is fixedly installed on the first mounting rod 201. An anti-slip sleeve 21 is provided on the outer wall of the roller 12. It should be noted that the first mounting rod 201 facilitates the installation of the two rollers 12. The first connecting rod 202 and the second connecting rod 203 improve the stable connection between the first mounting rod 201 and the mounting tube 1. The anti-slip sleeve 21 made of elastic material prevents the rollers 12 from slipping during movement. It also allows the rollers 12 to open wider than the scraper 7 and the cleaning brush 8. When the scraper 7 and the cleaning brush 8 are just against the inner wall of the pipe, the protective sleeve 21 will be pressed tightly against the inner wall of the pipe by the unfolded rollers 12, preventing the entire device from rotating during cleaning. The second motor 13 can drive the rollers 12 to rotate, thereby moving the device inside the pipe.

[0019] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the second bracket 3 further includes a third connecting rod 301 hinged to the second adjusting sleeve 5 and a fourth connecting rod 302 hinged to the connector 6. The ends of the third connecting rod 301 and the fourth connecting rod 302, which are close to each other, are jointly hinged to a second mounting rod 303 for mounting the scraper 7 and the cleaning brush 8. It should be noted that the second mounting rod 303 facilitates the installation of the scraper 7 and the cleaning brush 8 during use, and the third connecting rod 301 and the fourth connecting rod 302 facilitate the connection of the second mounting rod 303 with the second adjusting sleeve 5 and the connector 6.

[0020] Specifically, the working principle of the gas pipeline dredging device in this oilfield is as follows: Before use, the electric telescopic rod 14 and the adjusting frame drive the first adjusting sleeve 4 and the second adjusting sleeve 5 to slide synchronously. The opening or closing range of the first support 2 and the second support 3 is adjusted according to the pipe diameter to complete the adjustment of the position of the scraper 7, the cleaning brush 8 and the roller 12, so that the scraper 7, the cleaning brush 8 and the roller 12 can all abut against the inner wall of the pipe. Then, an inlet is opened on the pipe to be dredged, and the device is placed in the pipe. The second motor 13 is started to drive the roller 12 to rotate, thereby moving the device inside the pipe. During the movement, the cable 11 can ensure the power supply and signal transmission of the device. When the cable 11 moves, the protective layer 10 will protect it to prevent wear and tear, and at the same time improve the overall strength of the cable 11. At the same time, the first motor 9 will drive the scraper 7 and the cleaning brush 8 installed on the second support 3 to rotate through the connector 6 to clean and dredge the blockage on the inner wall of the pipe.

[0021] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
