[0002] Oil, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry". Oil is stored in some areas of the upper crust. The main component is a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Sampling is required to detect the quality of oil during oil extraction and transportation. However, the existing oil detection sampling device uses a scooping device or an extraction device to extract oil, and then transfers the oil to a sample storage tube. A large amount of oil will remain in the sampling device, which is troublesome to clean and affects reuse. Utility Model Content

[0004] The technical solution adopted by the utility model is as follows: The utility model proposes a petroleum detection sampling device, including an oil storage tank, a glass observation window and an oil pumping structure, the glass observation window is arranged on the oil storage tank, the oil pumping structure is arranged on the oil storage tank, the oil pumping structure includes a sealing cover, an air nozzle, a connector one, an air suction pipe, an air suction pump, an oil inlet, a connector two and an oil suction pipe, the sealing cover is threadedly rotatably arranged on the oil storage tank, the air nozzle is fixedly arranged on the sealing cover, the connector one is threadedly rotatably arranged on the air nozzle, the air suction pipe is connected to the connector one, the air suction pump is connected to the air suction pipe, the oil inlet passes through the sealing cover, the connector two is threadedly arranged on the oil inlet, and the oil suction pipe is connected to the connector two.

[0005] Preferably, the sealing cover is arranged between the air nozzle and the oil inlet, and the connector is arranged between the air nozzle and the air extraction pipe.

[0006] In order to better achieve the sampling effect, the air nozzle is arranged parallel to the oil inlet.

[0007] In order to more quickly achieve the purpose of preventing oil from being pumped out, the air nozzle is not arranged to penetrate the sealing cover, and the oil inlet penetrates the sealing cover and is inserted into the oil storage tank.

[0008] Furthermore, the oil extraction pipe is a disposable item.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: In the oil detection sampling device proposed in this scheme, the vacuum pump draws negative pressure into the oil storage tank. At this time, the oil extraction pipe connected to the oil storage tank extracts the oil into the oil storage tank, thereby eliminating the step of transferring the oil. At the same time, the oil extraction pipe is a disposable device to avoid cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
