With the continuous increase of airport passenger and cargo flow, the amount of aviation fuel receiving and sending is also increasing. In order to ensure the safety of the aircraft and passengers, it is necessary to strictly detect the aviation fuel. For sampling of oil sample, a rope is usually used to gradually put the sampling cylinder into the oil sample, and then another rope is used to pull the sampling valve rod. Under the action of the gravity of the sampling cylinder, the spring in the sampling cylinder is compressed, the sampling valve rod moves relative to the sampling cylinder, and then sampling is carried out. However, this method can only sample one depth of oil sample at a time, and the sampling cylinder needs to be inserted multiple times to complete multiple sampling at different depths, which makes sampling inconvenient.
