The invention discloses an oil conveying pipeline heat and pump station pipe cleaning device and an operating method thereof, and is designed by aiming at solving the problem of oil conveying pipeline middle heat and pump station pipe cleaning. An upper station oil supply pipe of the pipe cleaning device is sequentially connected with a first three-way valve, a front ball valve, a second three-way valve, a pipe cleaning device receiving and sending valve, a third three-way valve, a back ball valve, a fourth three-way valve and a station outlet pipeline, wherein a first gate valve and a third gate valve are arranged between the first three-way valve and the third three-way valve, a second gate valve and a fourth gate valve are arranged between the second three-way valve and the fourth three-way valve, and the first gate valve, a heating and pressurizing metering region and the fourth gate valve are arranged between the third three-way valve and the fourth three-way. According to the oil conveying pipeline heat and pump station pipe cleaning device, the application of the pipe cleaning valve in the pipe cleaning operation is more effective, the receiving and the sending of the middle heat and pump station pipe cleaning device by one set of pipe cleaning device are realized for the first time, the occupied area and the investment can be saved, the station field plane arrangement can be favorably realized, the reduction of a pipe conveying flow rate and the conveying stop during the pipe cleaning device receiving and sending avoidance can be avoided, and the overhaul can be carried out under the condition of not influencing the production flow process.
