Description

Technical Field

[0001] This utility model relates to the field of oilfield pipeline technology, specifically to a device for cleaning and unblocking scale buildup on the inner wall of an oilfield pipeline. Background Technology

[0002] Oilfield pipelines are key infrastructure in the oil extraction and transportation system, used to efficiently and safely transport crude oil from production areas such as oilfield wellheads and gathering stations to refineries, oil storage depots or transshipment terminals. They are usually made of high-strength steel pipes and have high pressure resistance and corrosion resistance to adapt to the complex working conditions that may occur during crude oil transportation.

[0003] A search revealed a cleaning device for petrochemical pipelines disclosed in Chinese Patent Publication No. CN220277785U. This device allows for radial adjustment of the roller's position via a threaded connection between the mounting shaft and the base, enabling the roller to slide over pipelines of varying inner diameters. Movement of the sleeve along the connecting shaft rotates the first and second arms, causing the cleaning plate at the end of the second arm to radially contract or expand, thus allowing for close contact with the inner walls of oil pipelines of different inner diameters for cleaning. This device simultaneously enables radial adjustment of both the roller unit and the cleaning plate in the circumferential direction, expanding the range of pipe inner walls that can be cleaned.

[0004] However, the cleaning device used for petrochemical pipelines does not have a drying structure for the inside of the pipeline after cleaning, which makes it impossible to put it into subsequent use directly after cleaning, thus affecting the efficiency of pipeline use. Therefore, a scale cleaning and unblocking device for the inner wall of oilfield pipelines is proposed. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5A device for cleaning and unblocking scale buildup on the inner wall of an oilfield pipeline includes a pipeline body 1, an unblocking and flushing device 2 installed inside the pipeline body 1, and a cleaning and drying device 3 installed inside the pipeline body 1.

[0024] The dredging and flushing device 2 includes an equipment box 201. The equipment box 201 is movably connected inside the main pipe body 1. A drive motor 202 is fixedly installed on the inner left wall of the equipment box 201. A gear 203 is fixedly installed at the output end of the drive motor 202. A pipe rotary joint 204 is fixedly installed on the inner right wall of the equipment box 201. A rotating rod 205 is rotatably connected inside the equipment box 201. A telescopic hose 206 is fixedly installed on the right side of the pipe rotary joint 204. A nozzle 207 is fixedly installed on the outer surface of the rotating rod 205. A drill bit 208 is fixedly installed on the left side of the rotating rod 205. An installation block 209 is fixedly installed on the left side of the equipment box 201.

[0025] Furthermore, the cleaning and drying device 3 includes an electric heating rod 301, which is fixedly installed inside the equipment box 201. A fan 302 is fixedly installed inside the equipment box 201. A diverter pipe 303 is fixedly installed on the left side of the fan 302. A telescopic rod 304 is fixedly installed inside the mounting block 209. An air conveying plate 305 is fixedly installed at the output end of the telescopic rod 304. An air nozzle 306 is fixedly installed on the outer surface of the air conveying plate 305. An extension sleeve 307 is fixedly installed on the outer surface of the mounting block 209. A spring body 308 is fixedly installed inside the extension sleeve 307. A cleaning rod 309 is fixedly installed on most of the spring body 308.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, the external telescopic device is connected to the equipment box 201, and the telescopic hose 206 is connected to the external water pump. The electrical equipment inside the device is controlled by the external control panel. By controlling the device through the control panel, the equipment box 201 moves inside the pipe body 1 via the pulley rod. During the movement, turning on the drive motor 202 will drive one of the gears 203 to rotate. Since the two gears 203 mesh with each other, they will drive the rotating rod 205 to rotate.

[0027] Specifically, such as Figure 3 As shown, the rotation of the rotating rod 205 drives the drill bit 208 to rotate, clearing the inside of the pipe body 1. Then, by turning on the external water pump, clean water can be sent into the inside of the rotating rod 205 through the pipe rotary joint 204 and sprayed out through the nozzle 207. During the rotation of the rotating rod 205, the nozzle 207 will also rotate, so that the clean water sprayed out by the nozzle 207 will initially flush the inner wall of the pipe body 1.

[0028] Specifically, such as Figure 4 and Figure 5As shown, during the movement of the equipment box 201, the cleaning rod 309 will be kept in contact with the inner wall of the pipe body 1 by the action of the spring body 308, thereby cleaning the inner wall of the pipe body 1 through the cleaning rod 309. At the same time, the electric heating rod 301 can generate hot air inside the equipment box 201, and the fan 302 can send the generated hot air into the four air conveying plates 305 through the diversion pipe 303. Then, the telescopic rod 304 can drive the four air conveying plates 305 and the air nozzles 306 on them to extend out of the mounting block 209. Then, the hot air is sprayed out through the air nozzles 306 to quickly dry the inner wall of the pipe body 1.

[0029] In summary, the scale cleaning and unblocking device for the inner wall of the oilfield pipeline, through the equipment box 201 and the external telescopic device, controls the movement of the unblocking and flushing device 2 inside the pipeline body 1, unblocks the inside of the pipeline body 1, and performs preliminary flushing. Then, through the setting of the cleaning and drying device 3, the inside of the pipeline body 1 can be brushed and washed. After the cleaning is completed, the inside of the pipeline body 1 is dried with hot air, which accelerates the drying speed of the inside of the pipeline body 1 and improves the utilization rate of the pipeline body 1.
