[0002] Petroleum and its products are one of the main commodities imported and exported by my country. In the analysis and testing of oil products, whether representative samples can be obtained is the primary condition for accurately analyzing the physical and chemical properties of oil products.
[0003] According to the National Standard of the People's Republic of China "Manual Sampling Method for Petroleum Liquids" (GB / T4756), for sampling of large oil tanks, it is necessary to climb to the top of the oil tanks more than ten meters high for manual sampling. Manual sampling has the disadvantages of high labor intensity, high randomness of sampling positions, high operational risks, and easy to affect the quality of oil. As an intrinsically safe device, the automatic sampler has the advantages of accurate sampling, energy saving and environmental protection, and simple installation, and is being widely used.
[0004] After the automatic sampler finishes sampling, the oil in the sampling hose cannot be emptied. It is necessary to shake the sampler handle to empty and replace the sampling hose in the oil tank before the next sampling. However, this method cannot know the specific quality of the discharged oil. Personnel can only determine whether the oil in the sampling hose is completely discharged and emptied through empirical methods. This may result in the stored oil not being completely emptied, and the oil obtained being inconsistent with the oil actually in the oil tank, making the oil product unrepresentative.

[0021] During implementation, the upper sampling hose 81 , the middle sampling hose 91 and the lower sampling hose 101 fixed on the surface of the follow-up connecting float rod 7 will also float inside the tank body 1 .
[0022] Furthermore, if Figure 2 as well as Figure 3 As shown, a sampling reserved opening flange 12 is arranged on one side of the bottom of the tank body 1, and an external tank sampling mechanism 2 is installed on the surface of the sampling reserved opening flange 12. The external tank sampling mechanism 2 is used for sampling oil samples inside the tank body 1. The external tank sampling mechanism 2 includes a sampling outer frame 21, an upper sampling tube 22, a middle sampling tube 23, a lower sampling tube 24 and an automatic sampler 25.
