[0002] During transportation, oil may solidify and block pipelines. Especially when transporting crude oil with a high freezing point in cold regions, the oil that is not flowing in the oil pipeline exposed outdoors may block the pipeline due to improper handling or equipment problems. Once the oil pipeline is blocked, it is difficult to clear it.

[0003] In the prior art, a swirl type oil pipeline unblocking device includes a steam boiler, a fixed pulley, a cleaning conduit, a pressure sensor, a temperature sensor, a valve, a pressure pump, a connecting hose, a spiral cleaning joint, and a base. The fixed pulley is located at the bottom of the steam boiler, the cleaning conduit is located on the side surface of the steam boiler, the pressure sensor, the temperature sensor, and the valve are installed on the cleaning conduit, the pressure pump, the connecting hose, and the spiral cleaning joint are connected to the cleaning conduit in sequence, and the base is located at the bottom of the spiral cleaning joint. However, it cannot dredge the pipeline where the entire pipeline is blocked and there is no passage, and it also does not consider the problem of fire prevention and explosion prevention. If the solidified petroleum is dredged, the petroleum will liquefy after heating and partially vaporize, and the combustible gas may reach the lower explosion limit. The mixture of oil and water is prone to generate static electricity. Since the liquid outflow end can enter the air, once the static electricity is discharged, there may be a risk of combustion and explosion.

[0004] Therefore, a device for unblocking an oil pipe is provided to address the deficiencies in the prior art. Utility Model Content
