[0002] Oil sampling refers to the operation of taking sample oil during oil transportation. The ship must perform this operation at the loading port and the unloading port. At the loading port, sampling can be performed every 1-2 hours at the end of the wharf oil pipe, or uniform sampling can be performed in each oil tank according to relevant regulations. The sampling operation should be jointly performed by the shipper, the ship owner, and the quality inspection agency personnel. The oil sampling device is used for sampling operation when oil sampling.

[0003] A patent for oil product detection sampling device is disclosed (authorized announcement number CN218444654U). The entire oil product detection sampling device has a simple structure and a small volume. After sampling is completed, the sample oil can be transferred by directly moving the entire oil product detection sampling device.
