[0060] The beneficial effects of the technical solution of the present invention are as follows: the housing protects the in-line pour point measurement device for oil pipelines, the first pipeline provides a transport location for the oil, and the first branch tube intercepts the pour points. The bottom of the first branch tube is opened to direct the pour points from the in-line oil pipeline into the collection box, thereby quickly removing the pour points from the oil pipeline and improving its quality.

[0062] The working steps of the measuring device (online pour point measuring device for oil pipeline transportation) are as follows:

[0063] S1. The condensate of the oil product transported in the pipeline enters the first support tube 9 through the first opening and is intercepted by the filter screen. The first motor 18 rotates to drive the gear 19 to rotate. The rotation of the gear 19 drives the tooth groove 17 to move. The movement of the tooth groove 17 drives the blocking plate 11 to move. The movement of the blocking plate 11 drives the slide 16 to move. The movement of the slide 16 causes the blocking plate 11 to drive the limit rod 12 to move. The limit rod 12 moves to limit it. The bottom of the first support tube 9 is opened to allow the condensate of the oil product transported in the pipeline to flow into the collection box 8, thereby realizing the function of quickly removing the condensate of the oil product transported in the pipeline and improving the quality.

[0064] S2. When the oil pipeline is installed, the sealing ring 24 is driven to move. The movement of the sealing ring 24 drives the second support rod 22 to move. The movement of the second support rod 22 drives the second support plate 25 to move. The movement of the second support plate 25 drives the first spring 26 to move. The movement of the first spring 26 causes the second support plate 25 to drive the roller 30 to move. The movement of the roller 30 drives the eighth support rod 29 to move. The movement of the eighth support rod 29 drives the bearing to move. The movement of the bearing causes the eighth support rod 29 to drive the damping block 28 to move. The movement of the damping block 28 causes the sealing ring 24 to be sealed and connected to the connecting pipe, thereby achieving the function of sealing the connection of the oil pipeline measuring device to prevent leakage.

[0065] S3. The function of the third sleeve 32 is to provide mobile support for the fifth support rod 33. The function of the limit head 38 is to provide mobile limit for the sliding sleeve 37. The rotation of the second motor 39 drives the collecting tube 40 to rotate. The rotation of the collecting tube 40 drives the pull rope 41 to move. The movement of the pull rope 41 drives the fifth support rod 33 to move. The movement of the fifth support rod 33 drives the sliding sleeve 37 to move. The movement of the sliding sleeve 37 causes the fifth support rod 33 to drive the third spring 35 to move. The movement of the third spring 35 causes the fifth support rod 33 to drive the cleaning head 34 to move. The movement of the cleaning head 34 quickly cleans the ultrasonic detection head 6, thereby realizing the function of automatically cleaning the detection head of the oil pipeline online solidification point measurement device.

[0066] S4 and the protective net 50 serve to block dust, and the sixth opening 49 serves to facilitate the entry of wind. The third box 42 has a built-in water source, and the water pump 46 rotates to draw water into the cooling pipe 47. At this time, the fan 48 rotates to generate wind force so that the cold air on the surface of the cooling pipe 47 is blown toward the ultrasonic detection head 6 to quickly cool it down. The water source enters the inside of the nozzle 45 through the water pipe 44, and is sprayed to the cooling block 43 through the nozzle 45 to cool it down, which is convenient for recycling and realizes the function of quickly cooling the oil pipeline online freezing point detection device and improving work efficiency.
