Problems solved by technology
These methods have their own advantages and disadvantages, but they are generally not sensitive to the small leakage of the pipeline, so the specific location of the small leakage point cannot be accurately known, so the cost of excavating and replacing the pipeline in the later stage is high and the workload is heavy

The invention belongs to the technical field of transportation pipeline fault shooting and diagnosing and particularly relates to a precise locating device of crude oil transportation pipeline small leakage and a monitoring method of the crude oil transportation pipeline small leakage. The precise locating device of the crude oil transportation pipeline small leakage comprises multiple oil transportation pipes, and the multiple oil transportation pipes are connected through a flange. The outer side of the flange is sleeved with an outer cylinder in a connected manner. Two fixing plates are connected with the bottoms of the oil transportation pipes. An infrared emitter is fixedly connected with one fixing plate. An infrared receiver is fixedly connected with the other fixing plate. Limitingclamp pipes are fixedly with the bottoms of the oil transportation pipes. According to the precise locating device of the crude oil transportation pipeline small leakage, through arrangement of oil absorbing paper, motors, the infrared emitter, the infrared receiver and a GPS locator, when the motor works, the oil absorbing paper is indirectly driven to move, when crude oil leaks, the oil absorbing paper absorb the crude oil and falls down under the action of gravity, so that the oil absorbing paper shields infrared rays emitted by the infrared emitter to the infrared receiver, and then real-time monitoring is achieved; the GPS locator provides the specific position information of the leakage, and locating of a leakage portion is achieved.
Description
technical field [0001] The invention belongs to the technical field of troubleshooting and diagnosis of transportation pipelines, and in particular relates to a precise positioning device and monitoring method for tiny leaks in crude oil transportation pipelines. Background technique [0002] Due to the relatively high viscosity of crude oil in the process of crude oil transportation in the buried crude oil transportation pipeline, in order to facilitate transportation and reduce transportation costs, it is necessary to heat the crude oil to a certain temperature before crude oil transportation, thereby reducing the viscosity of crude oil and improving the transportation of crude oil In order to reduce the heat transfer of crude oil during transportation, it is necessary to add additional insulation measures to the outside of the pipeline. Usually, the pipeline structure for transporting crude oil is as follows: first coat the outside of the oil pipeline with an anti-corrosi...
