Problems solved by technology

Offshore oil pipeline is one of the essential oil pipeline equipment in the process of offshore oilfield exploitation. However, with the continuous improvement of technical requirements for offshore oilfield exploitation, there are still some deficiencies in the cleaning of debris attached to the surface of offshore oil pipelines that need to be improved and dealt with urgently.
[0003] In the prior art, during the long-term working process of the offshore oil pipeline, the surface of the oil pipeline will gradually adhere to marine debris and impurities mixed in seawater. The surface of the oil pipe will cause corrosion and other effects, and then cause irreversible damage to the surface material of the oil pipe. These damages will directly reduce the service life of the oil pipe. significant economic loss

Embodiment 1

[0031] Such as Figure 1-5 As shown, a device for cleaning debris on the surface of offshore oil pipes, including oil pipe body 1, oil pipe body 1 is detachably connected with pipe clamps 2 through limit bolts, and adjacent pipe clamps 2 are arranged in cooperation to realize the clamping and fixing work of the device , it should be noted that the pipe collar 2 adopts a semi-circular structure, and both ends of the pipe collar 2 are provided with steps 21, and the adjacent steps 21 are detachably connected by limit bolts, so as to improve the disassembly and assembly of the device during cleaning. efficiency.

[0032] One group of pipe clamps 2 is fixedly connected with a drive assembly 3, the drive assembly 3 is meshed with the oil pipe body 1, and the pipe clamp 2 is slidingly connected to the oil pipe body 1 through the drive assembly 3 to realize the mobile cleaning work. It should be noted that the drive assembly 3 includes Drive motor 31 and gear rod 32, drive motor 31 ...

Embodiment 2

[0047] Such as Figure 6 Shown, the difference between this embodiment and embodiment 1 is:

[0048] The end of the movable groove 42 close to the oil pipe body 1 is provided with an alarm trigger piece 6, and the pull rod 52 is an electrical connecting rod, and the pull rod 52 and the alarm trigger piece 6 are slidingly connected. After the corrosion pits generated in the process reach a certain level, the scrub brush 5 will stretch through the pits under the magnetic attraction of the magnetic block 51 and contact the bottom of the pits. When the scrub brush 5 is stretched, it will drive the pull rod 52 and the movable groove 42 Sliding, when the pull rod 52 is in contact with the alarm trigger piece 6 at the bottom of the movable groove 42, the alarm is triggered and the alarm is performed to avoid excessive corrosion in the local area of ​​the oil pipe body 1, and the staff cannot detect in time that the oil pipe leaks The situation occurs.

Abstract

The invention belongs to the technical field of cleaning offshore oil pipes, and in particular relates to a device for cleaning debris on the surface of offshore oil pipes. Cooperate with each other to realize the clamping and fixing work of the device. One set of the pipe clamps is fixedly connected with the driving assembly, the driving assembly is engaged with the oil pipe body, and the pipe clamps are slidingly connected to the oil pipe body to realize the mobile cleaning work. The pipe hoop is detachably connected with a gear ring, and the gear ring is engaged with the driving assembly. The invention effectively solves the phenomenon of debris accumulation on the surface of the offshore oil pipeline during the long-term oil transportation work by setting a mobile rotary cleaning device for cleaning the debris on the surface of the offshore oil pipeline, thereby avoiding the occurrence of the corrosion of the material of the oil pipeline by debris, reducing the The labor intensity of the staff to regularly clean the oil pipe increases the service life of the oil pipe.

Description

technical field [0001] The invention belongs to the technical field of offshore oil pipeline cleaning, and in particular relates to a device for cleaning debris on the surface of offshore oil pipelines. Background technique [0002] The oil pipe is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed, and it is used to withstand the pressure generated during the production process. Offshore oil pipeline is one of the essential oil pipeline equipment in the process of offshore oilfield exploitation. However, with the continuous improvement of technical requirements for offshore oilfield exploitation, there are still some deficiencies in the cleaning of debris attached to the surface of offshore oil pipelines that need to be improved and dealt with urgently. [0003] In the prior art, during the long-term working process of the offshore oil pipeline, the surface of the oil pipeline will gradually adhere ...
