Description

Technical Field

[0001] This utility model relates to the technical field of oil pipe descaling devices, and in particular to an oil pipe descaling device for oilfield development. Background Technology

[0002] Oilfield development refers to the process of developing and extracting oil from industrially valuable oilfields discovered through geological exploration. Oil pipes are essential facilities in oilfield development, used for transporting oil. Due to the properties of oil, the inner walls of oil pipes tend to accumulate oil deposits over time. To prevent scale buildup from causing internal blockages and affecting oil transportation, descaling devices are needed to clean the inner walls of the oil pipes.

[0003] Traditional oil pipe descaling devices involve inserting a descaling device with a scraper into the oil pipe and using a motor to rotate the scraper to directly scrape away the grease buildup on the inner wall of the pipe. However, due to the variety of oil pipe specifications and their different inner diameters, the cleaning range of traditional scraper descaling devices is limited, and the scraper is not very effective at directly scraping away oil pipes with hardened scale layers. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an oil pipe descaling device for oilfield development, which aims to improve the problem that the scraper of the existing oil pipe descaling device has a limited scraping range and the scraper is not effective in directly scraping oil pipes with hard scale layers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil pipe descaling device for oilfield development, comprising a base and a vibrating base. A motor is fixedly connected to the inner wall of the base, and a rotating base is fixedly connected to the output end of the motor. Multiple guide shells are fixedly connected to and pass through the inner wall of the rotating base. A slider is slidably connected to the inner wall of the guide shell, and a sliding column is fixedly connected to the outer wall of the slider. A scraper is installed at one end of the slider. A turntable is rotatably connected to the inner wall of the rotating base. Multiple connecting rods are fixedly connected to the inner wall of the rotating base, and an eccentric wheel is slidably connected to the outer wall of the connecting rod. Multiple vibrating rods are slidably connected to and pass through the inner wall of the vibrating base. A quick-release assembly is provided inside the base.

[0006] Preferably, the quick-release assembly includes multiple pull rods, which are slidably connected and pass through the inner wall of the base. A long rod is fixedly connected to the outer wall of the pull rod, and a spring is sleeved on the outer wall of the pull rod. Both ends of the long rod are hinged to hinge rods, and one end of the hinge rod is hinged to a locking rod. Multiple locking blocks are fixedly connected to the outer wall of the rotating seat.

[0007] Preferably, the turntable is slidably connected to the outer wall of the guide shell, and the inner wall of the turntable has multiple sliding grooves that extend through it, with the sliding column slidably connected to the inner wall of the sliding grooves.

[0008] Preferably, the inner wall of the vibrating seat is rotatably connected to a chassis, the outer wall of the chassis is fixedly connected to a telescopic rod, and the eccentric wheel is fixedly connected to one end of the telescopic rod.

[0009] Preferably, a connecting block is fixedly connected to the outer wall of the vibrating rod, a spring is sleeved on the outer wall of the vibrating rod, and the bottom end of the vibrating rod is slidably connected to the outer wall of the eccentric wheel.

[0010] Preferably, one end of the spring is fixedly connected to the inner wall of the vibrating seat, and the other end of the spring is fixedly connected to the outer wall of the connecting block.

[0011] Preferably, one end of the second spring is fixedly connected to the inner wall of the base, and the other end of the second spring is fixedly connected to the outer wall of the long rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the motor drives multiple guide shells on the rotating seat to rotate, thereby driving the slider with scraper to slide along the groove, so that the scraper can adapt to oil pipes with different inner diameters to remove oil stains.

[0015] 2. In this utility model, the eccentric wheel is driven to slide by the telescopic rod. When rotating, the outer wall of the eccentric wheel is in contact with the vibrating rod, which drives it to repeatedly slide and vibrate the scale on the inner wall of the oil pipe, so that it can be dispersed and easily scraped off later.

[0016] 3. In this utility model, the tension rod drives the long rod to compress the spring to slide, which in turn drives the hinge rod and the locking rod to retract and slide on the inner wall of the base, disengaging from the locking block.

Detailed Implementation

[0023] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an oil pipe descaling device for oilfield development, comprising a base 1 and a vibrating seat 4. A motor 2 is fixedly connected to the inner wall of the base 1, and a rotating seat 3 is fixedly connected to the output end of the motor 2. Multiple guide shells 5 are fixedly connected to and pass through the inner wall of the rotating seat 3. A slider 6 is slidably connected to the inner wall of the guide shell 5, and a sliding column 7 is fixedly connected to the outer wall of the slider 6. A scraper 8 is installed at one end of the slider 6. A turntable 9 is rotatably connected to the inner wall of the rotating seat 3, and multiple connecting rods 16 are fixedly connected to the inner wall of the rotating seat 3. An eccentric wheel 12 is slidably connected to the outer wall of the connecting rods 16. Multiple vibrating rods 13 are slidably connected to and pass through the inner wall of the vibrating seat 4. A quick-release assembly is provided inside the base 1. The turntable 9 is slidably connected to the outer wall of the guide shell 5. Multiple sliding grooves are opened and pass through the inner wall of the turntable 9, and the sliding column 7 is slidably connected to the inner wall of the sliding groove.

[0025] Specifically, the internal components are protected and supported by the base 1, rotating seat 3, and vibrating seat 4. The motor 2 drives the scraper 8 to scrape the oil pipe, while simultaneously driving the vibrating rod 13 to vibrate the oil deposits on the inner wall, breaking up the scale buildup. The vibrating rod 13 is installed in front of the scraper 8; during descaling, vibration precedes scraping, thus increasing descaling efficiency. The rotation of the motor 2 drives the rotating seat 3 to rotate, which in turn drives the guide shell 5 fixed on the inner wall of the rotating seat 3 to rotate around the center. As the slider 6 on the inner wall of the guide shell 5 rotates, the sliding column 7 fixed on its outer wall slides in the groove of the turntable 9, causing the slider 6 to slide synchronously along the inner wall of the guide shell 5, driving the scraper 8 to slide until it abuts against the inner wall of the oil pipe, thus achieving the adaptability of the scraping component to oil pipes of different inner diameters. While the rotating seat 3 rotates, the vibrating rod 13 is driven to rotate synchronously through multiple connecting rods 16, so that the outer wall of the inclined surface of the vibrating rod 13 repeatedly contacts the vibrating rod 13, and the vibrating rod 13 slides and rises and falls repeatedly along the inner wall of the vibrating seat 4, thereby striking the inner wall of the oil pipe and achieving the effect of vibration.

[0026] Reference Figure 1 and Figure 5 The quick-release assembly includes multiple pull rods 18, which are slidably connected and pass through the inner wall of the base 1. A long rod 19 is fixedly connected to the outer wall of the pull rod 18, and a spring 20 is sleeved on the outer wall of the pull rod 18. Both ends of the long rod 19 are hinged to hinge rods 21, and one end of the hinge rod 21 is hinged to a locking rod 22. Multiple locking blocks 17 are fixedly connected to the outer wall of the rotating seat 3. One end of the spring 20 is fixedly connected to the inner wall of the base 1, and the other end of the spring 20 is fixedly connected to the outer wall of the long rod 19. The locking rod 22 is slidably connected to the inner wall of the base 1. A locking groove 23 is opened and passes through the inner wall of the locking block 17, and the locking rod 22 is slidably connected to the inner wall of the locking groove 23.

[0027] Specifically, in the default state, the rotating seat 3 is engaged inside the base 1 by the locking block 17. When the internal components need to be replaced, the pull rod 18 needs to be pulled outward. The pull rod 18, along with the long rod 19 fixed to its outer wall, slides synchronously, thereby compressing the second spring 20. This causes the hinge rod 21, which is hinged at both ends of the long rod 19, to drive the locking rod 22 to slide, so that the locking rod 22 disengages from the slot 23 on the slide column 7. At this time, the rotating seat 3 can be pulled out for component replacement. After the maintenance is completed, the pull rod 18 is pulled again, the slide column 7 is inserted, and the pull rod 18 is released to complete the installation. The stress of the second spring 20 ensures the reset and repeated use of the components.

[0028] Reference Figure 3The inner wall of the vibrating base 4 is rotatably connected to the chassis 10, and the outer wall of the chassis 10 is fixedly connected to the telescopic rod 11. The eccentric wheel 12 is fixedly connected to one end of the telescopic rod 11. The outer wall of the vibrating rod 13 is fixedly connected to the connecting block 14. The outer wall of the vibrating rod 13 is fitted with a spring 15. The bottom end of the vibrating rod 13 is slidably connected to the outer wall of the eccentric wheel 12. One end of the spring 15 is fixedly connected to the inner wall of the vibrating base 4, and the other end of the spring 15 is fixedly connected to the outer wall of the connecting block 14.

[0029] Specifically, because the inner diameter of the oil pipe is different, the vibration assembly also needs to be adjusted in range. When adjustment is required, the telescopic rod 11 is activated, which drives the eccentric wheel 12 to slide along the outer wall of the connecting rod 16, so that the conical outer wall of the eccentric wheel 12 can fit against the bottom end of the vibration rod 13, so that the vibration rod 13 can slide to expand the vibration range when the motor 2 is not started. When vibrating, the spring 15 will be compressed to prevent the vibration effect from being too strong, while ensuring the reset of the assembly.

[0030] Working principle: When using this descaling device, start the telescopic rod 11, which drives the eccentric wheel 12 to slide. Adjust the position of the eccentric wheel 12 according to the inner diameter of the oil pipe so that the vibrating rod 13 can touch the inner wall of the oil pipe. Then, put the device into the oil pipe, start the motor 2, and drive the rotating seat 3 to rotate. Multiple guide shells 5 fixed on the inner wall of the rotating seat 3 rotate synchronously, which drives the slider 6 installed on the inner wall of the guide shell 5 to rotate around the axis. During the rotation, the sliding column 7 installed on the slider 6 slides along the sliding groove on the turntable 9, thereby driving the slider 6 to extend and retract, so that the scraper 8 slides synchronously until it touches the inner wall of the oil pipe. After that, the scraper 8 will continue to contact the inner wall to scrape off the oil stains.

[0031] When the rotating seat 3 rotates, it drives the eccentric wheel 12 to rotate synchronously through multiple connecting rods 16. The outer wall of the eccentric wheel 12 will be in contact with the bottom of multiple vibrating rods 13, causing them to slide repeatedly along the irregular outer wall of the cam of the eccentric wheel 12, vibrating the scale on the inner wall of the oil pipe, dispersing it, and making it easy to scrape off.

[0032] When the scraper 8 needs to be replaced, pull the lever 18 outward to cause the long rod 19 to compress the spring 20. This causes the locking rods 22 on both sides to retract inward through the hinge rod 21, disengaging from the locking block 17. After that, the rotating seat 3 can be removed to replace and maintain the internal components.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
