Detection device capable of moving in pipeline in offshore drilling platform pipeline

Abstract

The invention relates to a detection device capable of moving in a pipeline in an offshore drilling platform pipeline. The detection device comprises a main body, an ejector rod and a rotating frame,wherein the top of the main body is connected with a cleaning motor, the top of the cleaning motor is connected with a rotating disc, the main body and the cleaning motor are connected through screws,the cleaning motor is connected with the rotating disc through screws, the ejector rod is arranged at the top of the rotating disc, the rotating disc is movably connected with the ejector rod, the rotating frame is arranged on the outer side of the rotating disc, the rotating frame is movably connected with the rotating disc, a material guide pipe is fixed on the inner side of the main body, a cleaning fan is arranged on the inner side of the material guide pipe, and the cleaning fan and the material guide pipe are connected through screws. The detection device has the beneficial effects thatthe detection device capable of moving inside the pipeline is arranged on the pipeline of the offshore drilling platform, a cleaning brush is arranged, the inner wall of the pipeline can be cleaned,therefore the inner diameter of the pipeline can be prevented from being reduced due to long-time use of the pipeline, so that the situation that the flow in the pipeline is reduced is avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a detection device for offshore drilling platform pipelines that can move inside the pipeline. Background technique [0002] Pipelines of different specifications are often used in metallurgy, petroleum, chemical and other fields, and the environment of these pipelines is usually extremely harsh, and they are easily corroded and aged during use. The potential risks cannot be ignored, so regular inspections are required. In order to ensure the safe and efficient operation of the pipeline system, the detection device for the pipeline of the offshore drilling platform is a device for detecting and repairing the pipeline of the drilling platform. [0003] The pipeline detection equipment disclosed in the Chinese invention patent application publication CN 104614248 A, although the pipeline detection equipment overcomes the fact that in the prior art, there is no detection ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a detection device for offshore drilling platform pipelines that can move inside the pipeline, so as to solve the problem that the existing detection devices proposed in the above background technology are inconvenient to automatically carry out deep movement during use, thus causing device detection. The time consumption is large, which makes the detection efficiency low, and the internal ratio of the pipeline may accumulate debris in the later period of long-term use, resulting in flow problems
