[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides an oil well hot washing and wax removal and replacement device, which includes: a support tube 1 and an annular cleaning brush 4. The bottom of the support tube 1 is provided with a guide component 3, and the outside of the support tube 1 is provided with a drive component 2.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 5The driving assembly 2 includes a support frame 21, which is fixedly sleeved on the outside of the support tube 1. A plurality of groups of evenly distributed telescopic columns 22 are mounted on the side walls of the support frame 21. The ends of the telescopic columns 22 on the same side are provided with the same fixedly connected mounting frame 221. A rotatably connected driving wheel 24 is mounted inside the mounting frame 221, and a driving motor 241 for driving the driving wheel 24 is fixedly mounted on the side wall of the mounting frame 221. A plurality of batteries 211 are fixedly mounted on the outer wall of the support frame 21. A fixedly connected control box 212 is provided on the outer wall of the support frame 21. A fixedly connected guide frame 23 is mounted on the outer wall of the support frame 21 relative to the mounting frame 221. The inner wall of the guide frame 23 is abutted against and slidably connected to the side wall of the mounting frame 221. A fixedly connected protruding rod 222 is mounted on the side wall of the mounting frame 221 relative to the guide frame 23. A threaded limit sleeve 223 is sleeved on the outer wall of the protruding rod 222, and the end of the limit sleeve 223 is abutted against the outer wall of the guide frame 23.

[0028] It should be noted that: through the movable installation of the mounting frame 221, before using the present device, the staff can first control the mounting frame 221 to slide as needed, thereby adjusting the position of the driving wheel 24 in the mounting frame 221, thereby changing the diameter specification of the annular structure formed by the multiple driving wheels 24. After the position of the driving wheel 24 is adjusted, the limiting sleeve 223 can be controlled to rotate so that the end of the limiting sleeve 223 abuts against the outer wall of the guide frame 23, thereby achieving the locking of the adjusted mounting frame 221, and then the driving wheel 24 in the present device can smoothly abut against the inner wall of oil well pipes of different specifications, thereby increasing the applicability of the present device when used;

[0029] After the adjustment of the driving wheel 24 is completed, the device is placed inside the oil well pipe. The working driving motor 241 can drive the driving wheel 24 to rotate, thereby making the device move more smoothly in the oil well pipe, reducing the jamming phenomenon during the movement, and accurately controlling the movement and cleaning speed of the device, thereby improving the user experience of the device.

[0030] In this embodiment, when installing the device, the external traction rope can be connected to the hanging ring in the support frame 21. Then, when the battery 211 is low on power during subsequent use, the staff can pull the traction rope to remove the device from the oil well pipe.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 5The deflection pipe 312 is fixedly mounted on the outer wall of the deflector box 31 and is connected to the deflection pipe 31 at the bottom end of the deflector box 31. The deflection pipe 31 is fixedly mounted on the outer wall of the deflector box 31 and is connected to the deflection pipe 31 at the bottom end of the deflector box 31. The deflection pipe 31 is fixedly mounted on the outer wall of the deflector box 31 and is connected to the deflection pipe 31 at the bottom end of the deflector box 1.

[0032] It should be noted that: by setting up the blades 32 inside the guide box 31, when in use, the steam entering the guide box 31 will resist the blades 32, driving the blades 32 to rotate, thereby converting the flow force when the steam is injected into the driving pipe 33, so that the driving pipe 33 can smoothly drive the annular cleaning brush 4 on the outer wall to rotate. Through the rotation of the annular cleaning brush 4, the inner wall of the oil well pipe can be quickly cleaned;

[0033] And because the annular cleaning brush 4 is fixedly connected to the outer wall of the driving tube 33 by bolts, during subsequent use, the staff can take out the corresponding annular cleaning brush 4 and connect it to the driving tube 33 according to the specifications of the oil well pipes to be cleaned, thereby enabling the device to smoothly clean oil well pipes of different specifications.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 5 A plurality of annularly distributed air inlet holes 331 are provided on the outer wall of the driving tube 33, and a rotatably connected adapter sleeve 34 is sleeved on the outer wall of the driving tube 33 and the air inlet holes 331. A fixedly connected adapter tube 341 is inserted into the interior of the adapter sleeve 34, and the end of the adapter tube 341 away from the adapter sleeve 34 is fixedly connected to the opposite part of the through hole 311 on the other side of the outer wall of the guide box 31. The bottom end of the driving tube 33 is fixedly installed with a fixedly connected air guide plate 35 by bolts, and the interior of the air guide plate 35 is connected to the interior of the driving tube 33. The outer wall of the air guide plate 35 is fixedly mounted with a connected air guide ring 351, and the interior of the air guide tube 312 is fixedly inserted with a plurality of annularly distributed nozzles 352.

[0035] It should be noted that: by installing the air guide ring 351 on the bottom end of the drive tube 33, during use, when the blade 32 drives the drive tube 33 to rotate, the multiple nozzles 352 can rotate synchronously, thereby achieving a more comprehensive steam spraying on the inner wall of the oil well pipe, thereby making the interior of the oil well pipe more evenly heated, thereby helping to improve the cleaning efficiency.

[0036] The working principle of the oil well hot washing wax removal and replacement device provided by the utility model is as follows:

[0037] When using the device, the staff can first take out the corresponding annular cleaning brush 4 and the air guide ring 351 as needed and install them on the driving tube 33, then move the installation frame 221 on the outer wall of the guide frame 23 to adjust the position of the driving wheel 24, thereby changing the diameter of the annular structure formed by the multiple driving wheels 24. In addition, during use, the device can be smoothly installed inside oil well pipes with different inner diameters, thereby increasing the applicability of the device.

[0038] After the device is placed inside the oil well pipe to be cleaned, the pipeline of the external steam generator can be connected to the docking pipe 11 at the same time, so that the steam generated by the external steam generator can flow into the support tube 1 through the docking pipe 11 and flow into the air guide pipe 312 through the exhaust hole 12 at the bottom of the support tube 1. At this time, the steam entering the air guide pipe 312 will enter the guide box 31. As the steam is continuously injected, the injected steam will drive the blades 32 inside the guide box 31 to rotate. At this time, the rotating blades 32 will drive the driving tube 33 at the end and the annular cleaning brush 4 and the air guide ring 351 on the outer wall thereof to rotate. By rotating the annular cleaning brush 4, the inside of the oil well pipe can be scraped and cleaned;

[0039] The steam generated by the rotation of the driving blades 32 flows into the driving pipe 33 through the transfer pipe 341 on the other side. The steam then flows through the driving pipe 33 into the air guide plate 35 and the air guide ring 351 and is smoothly discharged outward through the nozzle 352 on the air guide pipe 312, thereby dissolving and cleaning the wax agglomerated on the inner wall of the oil well pipe.

[0040] During this process, external staff can also control and send signals to the terminal controller to control the drive motor 241 to work. The working drive motor 241 will drive the drive wheel 24 to rotate, thereby enabling the device to move downward stably inside the oil well pipe, thereby achieving stable cleaning of the inner wall of the oil well pipe.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0042] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
