Oil-gas field pipeline interior corrosion detection and spraying damage repairing device

Abstract

The invention relates to an oil-gas field pipeline interior corrosion detection and spraying damage repairing device. The device comprises a shell, an ultrasonic sensor, a main unit, a first driving device and a mobile terminal. The two ends of the lower end of the shell are provided with multiple drive wheel assemblies and multiple driven wheel assemblies respectively, and the periphery surface of the shell is provided with guide wheel assemblies and transparent covers. Illumination devices and camera shooting devices are arranged in the transparent covers one to one. The ultrasonic sensor isarranged in any transparent cover. A first driving device is arranged in the shell and rotatably connected with a rotation disc through a rotation shaft. The rotation disc is provided with a polishing assembly and a liquid spraying disc. The liquid inlet end of a liquid pumping device in the shell is connected with a liquid outlet of a liquid storage box, and the liquid outlet end of the liquid pumping device is connected with a liquid inlet of a liquid spraying disc. The main unit is arranged in the shell, and a central processor and a communication module which are used for controlling electrical equipment are arranged in the main unit. The central processor is in communication connection with the mobile terminal through the communication module. The oil-gas field pipeline interior corrosion detection and spraying damage repairing device can complete corrosion detection and repairing work on the inner wall of a pipeline at a time.

Description

Technical field [0001] The invention relates to the technical field of pipeline internal detection and repair, in particular to an oil and gas field pipeline internal corrosion detection and spray damage repair device. Background technique [0002] The pipeline is a tool for fluid transmission, because most of the fluid medium is corrosive, which will cause corrosion to the inner wall of the pipeline during the transmission process. Once the pipeline is corroded and perforated, the fluid in the pipeline will leak, and the fluid delivery will be interrupted. The fluid medium can cause environmental pollution, fire and other disasters. Oil and gas field refers to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs in the same area controlled by a single local structural unit. If there are only oil reservoirs in this local structure, it is called an oil field; only gas reservoirs are called a gas field; the pipelines of oil and gas fields need to be tested regular...

Problems solved by technology

If there are only oil reservoirs in this local structure, it is called an oil field; if there are only gas reservoirs, it is called a gas field; the pipelines in oil and gas fields need to be regularly tested for corrosion during use, and the corrosion of pipelines can be timely and effectively checked. repair to avoid disasters; however, the existing corrosion detection in the pipeline and pipeline repair are completed by two different equipment, and the damaged part of the pipeline is often repaired after the damaged part is detected; but the above operation greatly increases the pipeline Maintenance time reduces work efficiency; for this reason, this application proposes an oil and gas field pipeline internal corrosion detection and spraying damage repair device
