[0014] Beneficial effects

[0015] The utility model provides an instrument for measuring the pour point, solidification point, cloud point and cold filter plugging point of petroleum products. It has the following beneficial effects:

[0016] (1) The pour point, solidification point, cloud point and cold filter plugging point tester of a petroleum product has a cleaning mechanism and a driving mechanism. When the heat sink needs to be cleaned, the motor on the threaded rotating rod drives the threaded rotating rod to rotate. The rotation of the threaded rotating rod can drive the sliding block connected to it to slide in the sliding groove, and then the connecting rotating rod and the cleaner on it are driven to move synchronously through the connecting plate. The movement of the connecting plate drives the driven gear to move through the rotating rod, and the driven gear is engaged with the outer wall of the gear bar, so that the driven gear can rotate while moving. The rotation of the driven gear drives the second bevel gear engaged with the first bevel gear to rotate through the rotating rod and the first bevel gear.
