[0001] This invention relates to the field of petroleum exploration technology, specifically to a pipeline cleaning device for petroleum exploration and its working method. Background Technology

[0002] Petroleum exploration refers to the process of using various exploration methods to understand the underground geological conditions, recognize the conditions for oil generation, storage, migration, accumulation, and preservation of oil and gas, comprehensively evaluate the oil and gas potential, identify favorable areas for oil and gas accumulation, find oil and gas traps, explore the area of ​​oil and gas fields, and clarify the oil and gas layer conditions and production capacity in order to find and identify oil and gas resources.

[0016] A cleaning method for a pipeline cleaning device used in oil exploration, the cleaning method further includes the following steps:

[0017] S1. By rotating the connecting column, the connecting column drives the rotating plate to rotate, and the rotation of the rotating plate drives the locking screw to rotate. The locking screw moves inward under the threaded connection between the locking screw and the threaded sleeve, and the locking screw drives the clamping plate to move. The clamping plate provides limiting support for the oil pipeline.

[0018] S2. Then connect an external water spraying device to spray water onto the surface of the pipe. At this time, the lower servo motor drives the drive wheel to rotate. The rotation of the drive wheel causes the belt to drive the driven wheel to rotate. The rotation of the driven wheel drives the shaft to rotate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention connects to an external water spraying device to spray water onto the pipe surface. At this time, the lower servo motor drives the drive wheel to rotate, and the rotation of the drive wheel causes the belt to drive the driven wheel to rotate, which in turn drives the shaft to rotate. The rotation of the shaft causes the right positioning mechanism to rotate, thereby driving the pipe to rotate. This solves the problem that when the cleaning device is used, it simply sprays water to clean, which makes it difficult to clean the deposits on the pipe surface and thus results in poor cleaning effect.

[0022] 2. The present invention enables the cleaning roller to rotate smoothly inside the cleaning shroud by setting the groove, and enables the drive gear to rotate smoothly inside the cleaning shroud by setting the through groove, thereby ensuring the transmission effect. By setting the guide slide, the moving position of the adjusting screw sleeve is guided, thereby improving the stability of the adjusting screw sleeve during movement and preventing displacement.

A light rod 209 is fixedly connected to the inner cavity of the driven gear 208. A cleaning roller 203 is movably connected to the surface of the light rod 209.

[0035] Specifically, grooves 202 are provided around the inner cavity of the cleaning sleeve 201, and the light rod 209 is movably connected to the inside of the grooves 202. Through grooves 207 are provided around the inner wall of the cleaning sleeve 201, and the drive gear 206 is movably connected to the inside of the through grooves 207.

[0036] Through the above technical solution, the groove 202 allows the cleaning roller 203 to rotate smoothly inside the cleaning cylinder cover 201, and the through groove 207 allows the drive gear 206 to rotate smoothly inside the cleaning cylinder cover 201, thereby ensuring the transmission effect.

[0037] Specifically, a connecting seat 204 is fixedly connected to the bottom of the drive motor 205, and one side of the connecting seat 204 is fixedly connected to the surface of the cleaning cylinder cover 201.

[0052] The specific implementation of the present invention is as follows: By rotating the connecting column 404, the connecting column 404 drives the rotating plate 403 to rotate. The rotation of the rotating plate 403 drives the locking screw 407 to rotate. The locking screw 407 moves inward under the threaded connection between the locking screw 407 and the threaded sleeve 405. The locking screw 407 drives the clamping plate 406 to move.
