Description

Technical Field

[0001] This utility model belongs to the field of oilfield pipe technology, and more specifically, it relates to an internal surface treatment device for oilfield pipes. Background Technology

[0002] Oil extraction pipes transport oil from underground formations to the surface. The pipe acts as a conduit, allowing oil to flow smoothly from the formation to the wellhead. During prolonged use, pipes require regular cleaning. Current cleaning methods typically involve water spraying, but this often results in deposits such as paraffin wax adhering to the inner walls of the pipe, which are difficult to remove completely by spraying. Therefore, this paper researches and improves upon existing structures and shortcomings, providing an internal surface treatment device for oil extraction pipes to achieve greater practical value.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides an internal surface treatment device for oilfield pipes, including a main body 1. A connecting cylinder 9 is rotatably connected to the top side of the main body 1. A protective shell 11 is fixedly installed on the outer side of the connecting cylinder 9. A connecting seat 15 for connecting a drive device is fixedly installed on the top side of the protective shell 11. Multiple sets of fixed seats 2 are symmetrically fixedly installed on the bottom side of the main body 1. A sliding rod 3 is slidably connected to the inner side of each set of fixed seats 2. One end of the sliding rod 3 passes through the fixed seat 2 and is fixedly connected to a steel brush 4.

[0026] The connecting cylinder 9 has a sliding rod 5 slidably connected to the inner side of its bottom end. The main body 1 has a through hole at its center for the sliding rod 5 to pass through. The bottom end of the sliding rod 5 is rotatably connected to a push block 6, which can drive the push block 6 to move flexibly.

[0027] Each of the multiple sets of sliding rods 3 has a movable block 7 fixedly installed on one end. Each of the multiple sets of movable blocks 7 has an inclined surface on the side near the push block 6. The bottom side of the push block 6 has a conical surface. The inclined surfaces of the multiple sets of movable blocks 7 abut against the conical surface of the push block 6. This allows the multiple sets of movable blocks 7 to move simultaneously when the push block 6 moves, and the position of the steel brush 4 to be flexibly adjusted.

[0028] The connecting cylinder 9 has a stud 10 threadedly connected to the inner side of its top end. The bottom end of the stud 10 is rotatably connected to the top end of the slide rod 5, which can enable the slide rod 5 to move flexibly.

[0029] Among them, a spring 8 is sleeved on the outer side of the slide bar 3. One end of the spring 8 abuts against one side of the moving block 7, and the other end of the spring 8 abuts against one side of the fixed seat 2, so that the moving block 7 can be automatically moved when the push block 6 rises.

[0030] The stud 10 has an internal hexagonal hole at its top, which allows for easy rotation of the stud 10.

[0031] The protective housing 11 has a drive motor 12 fixedly installed on the top side of its inner wall. A gear 13 is fixedly installed on the output end of the drive motor 12. A gear 14 is fixedly connected coaxially to the top side of the main body 1. The gear 13 and the gear 14 mesh with each other, which can enable the main body 1 to rotate easily.

[0032] The working principle of this embodiment is as follows: When it is necessary to clean the inner wall of the pipe, firstly, the drive motor 12 in the product is connected to an external power supply and control unit. Rotating the stud 10 drives the slide bar 2 5 to move. The slide bar 2 5 moves the push block 6. The push block 6 moves the moving block 7 and the slide bar 1 3. The slide bar 1 3 moves the steel brush 4 to a suitable position. Then, the main body 1 and the drive device that can drive the main body 1 to move are connected through the connecting seat 15. The drive motor 12 is started to drive the main body 1 to rotate. The main body 1 drives the steel brush 4 to rotate through the fixed seat 2 to clean the inner wall of the pipe. The drive device drives the main body 1 to move inside the pipe, thereby achieving efficient cleaning of the inner wall of the pipe and removing deposits such as paraffin.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
