[0002] With the popularization of cars and the increasing demand for travel, mobile cabin refueling equipment will be widely used in various fields. Cabin refueling stations are integrated with loading cabins and oil receiving and sending systems. Since the oil receiving and sending must strictly distinguish the import and export of the medium, the flow direction of oil pumping and refueling in the existing cabin refueling stations is fixed, and pipelines for oil receiving and sending need to be set up separately in the cabin, so that the entire oil receiving and sending system is large in size and difficult to put into the loading cabin.

[0003] The announcement number is CN 220412888 U, which discloses a vehicle-mounted oil receiving and sending device, and its technical solution is: the vehicle-mounted oil receiving and sending device is set in the car, when the third interface is the oil inlet, the C end and the A end of the first electric three-way reversing valve are connected, the C end and the B end of the second electric three-way reversing valve are connected, and the first interface and the second interface are the oil outlet; when the first interface and the second interface are the oil inlet, the B end and the C end of the first electric three-way reversing valve are connected, the A end and the B end of the second electric three-way reversing valve are connected, and the third interface is the oil outlet. Although this oil receiving and sending device can not distinguish the inlet and outlet pipelines of the oil, this device relies on the chassis engine to provide power and can only be used on the vehicle. When the oil receiving and sending system is loaded in the car, the placement direction of the oil receiving and sending system must be considered to avoid interference between vehicles during use, and the oil receiving and sending system cannot be moved after being fixed.
