The specific working process is as follows:

when the oil transportation device works, the heat preservation rings 3 are arranged between the inner pipeline 1 and the outer pipeline 2 at intervals, when oil is transported, firstly, a heating point is selected, the sealing cover 37 is opened, the heating device is inserted into the heating pipe 36, the heating device heats water flow in the heating pipe 36, and then the water flow in the heat preservation cavity is gradually heated, the heated water flow uniformly heats the inner pipe on one hand, meanwhile, the water flow also heats the power box 31, so that the mercury solution in the power box 31 is heated and expanded, the expanded mercury solution pushes the sliding plate 32 and the transmission rod 33 to move, and further drives the extrusion plate 34 to slide in the heat preservation cavity, when the extrusion plate 34 slides to the side far away from the power box 31, negative pressure and positive pressure are respectively formed on the left side and the right side of the heat preservation cavity, along with the continuous sliding of the extrusion plate 34, water flow in the cavity in the moving direction of the extrusion plate 34 in, in the process of conveying hot water, as the one-way conduction pipe 35 extends into the power box 31 of the adjacent heat preservation ring 3, the hot water heats mercury in the mercury box in the process of flowing in the one-way conduction pipe 35 to drive the next extrusion plate 34 to slide, the hot water drives the extrusion plate 34 to slide and simultaneously enter the heat preservation ring 3, and gradually dissipates heat and lowers the temperature along with the lapse of time, so that the mercury solution retracts, the extrusion plate 34 resets, meanwhile, a cavity of the heat preservation cavity, which is positioned on the opposite side of the movement direction of the extrusion plate 34, gradually extracts water flow in the previous heat preservation ring 3 under the action of negative pressure, the temperature of the water in the heat preservation cavity is gradually reduced along with the gradual addition of cold water in the extraction process, so that the extrusion plate 34 gradually slides in the reverse direction under the drive of the reverse reset sliding plate 32, the one-way plug on the reverse sliding extrusion plate 34 is opened under the action of water pressure, the flow of the water flow is completed.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
