Technical Field

[0001] This application relates to the field of oil pipeline cleaning technology, and in particular to a crude oil pipeline cleaning device. Background Technology

[0002] Since most of the crude oil produced in my country is high-wax crude oil, the wax in the crude oil will precipitate and deposit on the pipe wall during pipeline transportation due to changes in thermal conditions along the pipeline, forming a wax layer of a certain thickness. Over time, the wax will accumulate, age, and harden, which will lead to a smaller pipeline flow radius, a relative increase in pressure, a decrease in pipeline transportation capacity, an increase in operating energy consumption, and accelerated pipe wall corrosion, increasing pipeline operation and maintenance costs. Therefore, it is necessary to clean crude oil pipelines regularly.

[0003] In related technologies, crude oil pipelines are mainly cleaned using mechanical cleaning equipment, which uses pipe brushes inserted into the pipeline to mechanically scrub and remove deposits from the pipe walls.

[0004] However, due to the different diameters of oil pipelines, different sizes of pipe brushes need to be replaced during the oil pipeline cleaning process, which is not only cumbersome to operate, but also inefficient in cleaning.

[0005] Therefore, those skilled in the art have provided a crude oil pipeline cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0034] Reference Figure 1 , Figure 3 as well as Figure 4 The cleaning component 31 includes a protective shell 311 installed at one end of the rotating rod 2. Scraper plates 312 are provided at the top and bottom of the protective shell 311. A rack 313 is fixedly installed on the adjacent side of the two scraper plates 312. The ends of the two racks 313 away from the scraper plates 312 pass through the protective shell 311 and extend into the interior of the protective shell 311. A servo motor 314 is installed on one side of the protective shell 311. The output end of the servo motor 314 passes through the protective shell 311 and extends into its interior. A gear 315 is fixedly installed on the output end of the servo motor 314. The gear 315 and the rack 313 are meshed.

[0035] In this embodiment, the servo motor 314 drives the gear 315 to rotate, and the gear 315 drives the two scraper blades 312 to move inward and outward synchronously through the meshing connection with the rack 313, so as to adjust them to fit against the inner wall of the oil pipeline.

[0036] Please continue to refer to Figure 3 The rotating rod 2 is mounted on the surface inside the housing 1 with a worm gear 316. A drive motor 317 is mounted on one side inside the housing 1. A worm 318 is fixedly mounted on the output end of the drive motor 317. The worm 318 and the worm gear 316 are meshed together.

[0037] In this embodiment, the operation of the drive motor 317 drives the worm 318 to rotate, and the meshing connection between the worm wheel 316 and the worm 318 drives the scraper plate 312 to rotate, thereby scraping away the oil stains in the oil pipeline.

[0038] Please continue to refer to Figure 4 On the other side of each of the two scraper blades 312, a sleeve rod 319 is fixedly installed. The end of the two sleeve rods 319 away from the scraper blades 312 passes through the protective shell 311 and extends into it. The end of the rack 313 located inside the protective shell 311 passes through the sleeve rod 319 and is slidably connected to it.

[0039] In this embodiment, the rack 313 inserts into the sleeve 319 when it moves within the protective housing 311, so as to provide more space for the rack 313 to move.

[0040] Reference Figure 1 as well as Figure 2 The moving component 32 includes a crossbar 321 disposed around the outside of the housing 1. A fixed seat 322 is fixedly installed on the surface of the crossbar 321. Slide grooves 323 are provided around the outside of the housing 1.

A connecting hose 35 is connected to the side of the water storage tank 33 away from the rotating rod 2, and the end of the connecting hose 35 away from the water storage tank 33 is connected to an external water supply pipe.

[0044] In this embodiment, water can be supplied to the water tank 33 during cleaning so that the nozzle 34 can flush the inside of the oil pipeline.

[0045] The implementation principle of the crude oil pipeline cleaning equipment in this application embodiment is as follows: When cleaning oil pipelines of different diameters, the device is placed inside the oil pipeline. At this time, the moving component 32 on the surface of the housing 1 automatically adjusts by means of the cooperation between the telescopic rod 327 and the return spring to adapt to oil pipelines of different diameters, and the device reciprocates inside the oil pipeline by means of the movement of the electric roller 326.

[0046] When this device reciprocates within the oil pipeline, the servo motor 314 drives the gear 315 to rotate.
