The sleeve itself is a hollow structure and has a gap between itself and the outer sleeve. When the oil suction device is put into the oil layer, the top of the outer sleeve is located in the oil layer due to the buoyancy device. At this time, the oil in the oil layer flows into the outer sleeve from the gap. The sleeve body is a hollow structure, and the oil flowing into the outer sleeve from the gap lifts the sleeve. The top of the sleeve floats on the oil surface or is flush with the oil surface. When the suction device sucks the oil in the outer sleeve through the oil suction pipe, the sleeve sinks into the oil layer. The oil flows into the outer sleeve from the top of the sleeve and lifts the sleeve again so that the sleeve floats on the oil surface again. The oil in the outer sleeve is sucked synchronously. The sleeve sinks again. In this way, the sleeve can move back and forth in the oil layer. The floating oil on the surface of the oil layer can enter the outer sleeve periodically through the back-and-forth movement of the sleeve and then be sucked by the suction device. The sleeve automatically rises and falls under the action of the oil buoyancy. The floating oil enters the outer sleeve and is sucked by the oil suction pipe. As the oil decreases, the sleeve sinks and guides the floating oil into the outer sleeve again to realize cyclic oil suction. Manual adjustment is not required. The traditional oil suction device may need to be manually adjusted in height or position. However, the present device automatically operates based on the buoyancy and the change in oil level, reduces manual intervention, improves work efficiency, and reduces labor intensity.
