A microelectrode oil film thickness measuring device and its measuring method

Abstract

The invention belongs to the field of ocean monitoring and particularly provides a microelectrode measuring device for oil film thickness and a measuring method thereof. The microelectrode measuring device comprises a bracket platform, a stepper, a conductive reader and a conductive microelectrode, wherein the stepper and the conductive reader are respectively mounted on the bracket platform; a crude / fine adjusting knob is mounted on the stepper; one end of the conductive microelectrode is connected to the lower part of the stepper and has an up-and-down reciprocating motion under the action of the crude / fine adjusting knob; the other end of the conductive microelectrode is a free end and is provided with an oleophobic layer; and the conductive microelectrode is connected to the conductive reader through a wire. The measuring method comprises the following steps: utilizing the stepper to drive the conductive microelectrode to move up and down, thereby guiding the conductive microelectrode to contact with an oil film and water in turn, and then calculating a difference value of a displayed value of an index plate on the stepper according to the mutation of conductivity displayed bythe conductive reader, thereby acquiring the oil film thickness. In the microelectrode measuring device, the conductive microelectrode can be used for accurately measuring the fine change of the inner and outer conductivities of the oil film and the stepper has a crude / fine adjusting two-level stepping function and can be used for accurately boosting the shifting of the conductive microelectrode.

Description

technical field [0001] The invention belongs to the field of marine monitoring, in particular to a micro-electrode oil film thickness measuring device and a measuring method thereof, which can be used for direct measurement of oil film thickness in a laboratory. Background technique [0002] With the rapid development of the oil industry and offshore oil development, oil transportation on water is becoming more and more busy; oil spill accidents caused by factors such as sea damage, grounding on rocks, mechanical failure, and improper human operation are gradually increasing, especially large-scale oil spill accidents. The seriousness of its pollution has attracted worldwide attention. After an oil spill accident, the marine administrative department must carry out a large number of investigation and evidence collection work to determine the nature of the oil spill, the scale of the oil spill, the scope of possible impact and the degree of damage, etc., and then take a serie...

Problems solved by technology

Among the existing oil film thickness estimation methods, the methods with high precision and reliable technology itself, such as laser-acoustic oil layer thickness remote sensor, microwave radiometer method, etc., often have problems such as on-site operation difficulties and difficulty in offshore surveys, so that they cannot Step out of the laboratory and enter the practical application link

However, the oil color visual inspection method and the infrared-ultraviolet aerial remote sensing method that are often used now, the former color discrimination is limited by human subjective judgment, is greatly affected by the environment, and cannot be used at night; although the latter can detect extremely thin oil films thickness to make judgments, but it is easy to generate false information due to the interference of external environmental factors, and it is difficult to obtain ideal results
