A cleaning module for cleaning the detection head 7 is installed, and the cleaning module includes two cleaning plates 10 respectively placed on both sides of the detection head 7, one cleaning plate 10 is provided with a cleaning groove 11 matched with the detection head 7, and a cleaning sponge 12 is installed on the inner wall of the cleaning groove 11. During the rotation of the detection head 7, the detection head 7 can move in the cleaning groove 11 and contact with the cleaning sponge 12 to clean the detection head 7, and the other cleaning plate 10 is provided with a wiping groove 13 matched with the detection head 7, and a cleaning cloth 14 is installed on the inner wall of the wiping groove 13. During the rotation of the detection head 7, the detection head 7 can move in the wiping groove 13 and contact with the cleaning cloth 14 to clean the detection head 7.

[0021] A test tube rack 17 corresponding to the detection head 7 and an electric push rod 18 cooperating with the test tube rack 17 are provided on the placement table 2. The electric push rod 18 is fixed on the placement table 2 and pushes the test tube rack 17 to slide on the placement table 2. The electric push rod 18 is detachably connected to the test tube rack 17. The test tube rack 17 includes a plurality of limiting holes 19. The test tube rack 17 is provided with a plurality of sampling tubes 20, which are plugged into the limiting holes 19.

[0022] Working principle: When testing lubricating oil samples, the lubricating oil samples to be tested are placed in a number of collection tubes, and then the collection tubes are respectively inserted into a number of limiting holes 19 of the test tube rack 17. The hydraulic cylinder 4 drives the movable column 5 to move toward the test tube rack 17, so that the detection head 7 connected to the movable column 5 through the mounting rod 8 moves to the corresponding sampling tube 20 and enters the sampling tube 20 to test the lubricating oil sample. After the lubricating oil sample in the first sampling tube 20 is tested, the hydraulic cylinder 4 drives the movable column 5 to move toward the original test tube rack 17, so that the detection head 7 on the movable column 5 moves to the corresponding sampling tube 20 and enters the sampling tube 20 to test the lubricating oil sample. The head 7 is removed from the sampling tube 20, and the mounting rod 8 is rotated and connected to the rotating channel 9 of the movable column 5, so that the motor 6 works to drive the mounting rod 8 to rotate in the rotating channel 9, and the detection head 7 can be driven to rotate with the mounting rod 8 as the axis. During the rotation process, the detection head 7 passes through the cleaning groove 11 of a cleaning plate 10 and contacts the cleaning sponge 12 in the cleaning groove 11, so that when the detection head 7 passes through a cleaning plate 10 and moves in the cleaning groove 11, the cleaning sponge cleans the detection head 7, and the detection head 7 continues to rotate through the wiping groove 13 of another cleaning plate 10 and contacts the cleaning sponge 12 in the wiping groove 13. The cleaning cloth 14 of the detection head 7 is in conflict with the cleaning cloth 14, so that when the detection head 7 passes through another cleaning plate 10 and moves in the wiping groove 13, the cleaning cloth 14 further cleans the detection head 7, and the detection head 7 that has detected a lubricating oil sample can be cleaned in time, which is convenient for the detection head 7 to detect the next lubricating oil sample accurately. The detection head 7 continues to rotate 360 ​​degrees until it stops corresponding to the sampling tube 20 on the test tube rack 17. At the same time, the electric push rod 18 drives the test tube rack 17 to slide on the placement table 2 so that the next sampling tube 20 corresponds to the cleaned detection head 7, which is convenient for the detection head 7 to detect the next sampling tube 20. The lubricating oil sample is tested. When all the sampling tubes 20 are tested, the test tube rack 17 and the electric push rod 18 are disassembled and connected to remove the test tube rack 17 together with the sampling tube 20 thereon for subsequent cleaning. The sampling tube 20 is plugged into the limiting hole 19 to facilitate the sampling tube 20 to be removed from the test tube rack 17 for cleaning, so that it is convenient for the next use. Finally, when continuous testing of multiple samples is achieved, the detection head 7 can be cleaned in time to avoid the residue of the previous sample may affect the test result of the next sample, resulting in cross contamination problems, thereby improving the accuracy and reliability of the test results.

[0023] A cleaning plate 10 is provided with a liquid storage chamber 15 and a liquid guide hole 16 connected to the liquid storage chamber 15. The liquid guide hole 16 is connected to the cleaning tank 11 and corresponds to the cleaning sponge 12. Distilled water is added to the liquid storage chamber 15, and the distilled water enters the cleaning tank 11 through the liquid guide hole 16, and is then absorbed by the cleaning sponge 12 on the inner wall of the cleaning tank 11, so that the cleaning sponge 12 is filled with distilled water. When the detection head 7 passes through the cleaning tank 11 and collides with the cleaning sponge 12 for cleaning, the cleaning sponge 12 with distilled water can clean the detection head 7 more thoroughly, and when passing through the wiping tank 13 and collides with the cleaning cloth 14, the cleaning cloth 14 wipes off the distilled water remaining on the detection head 7 to improve the cleaning effect, further avoid the problem of cross contamination, and thus improve the detection accuracy of the detection head 7.

[0024] A first connecting rod 21 is installed on the test tube rack 17, and a threaded sleeve 22 is threadedly connected to the first connecting rod 21. A second connecting rod 23 threadedly connected to the threaded sleeve 22 is installed on the electric push rod 18, and the threaded sleeve 22 is threadedly connected to the first connecting rod 21 and the second connecting rod 23, so that the connection and disassembly of the first connecting rod 21 and the second connecting rod 23 can be controlled by rotating the threaded sleeve 22, so as to realize the disassembly connection between the electric push rod 18 and the test tube rack 17, so that it is convenient to take away the test tube rack 17 together with the sampling tube 20 for subsequent cleaning after the detection is completed, and at the same time reduce the deviation caused by the electric push rod 18 when the test tube rack 17 slides. A guide groove 24 cooperating with the test tube rack 17 is opened on the placement table 2, and the test tube rack 17 slides in the guide groove 24. The setting of the guide groove 24 avoids the deviation when the electric push rod 18 drives the test tube rack 17 to slide on the placement table 2, resulting in inaccurate correspondence between the next sampling tube 20 and the detection head 7, affecting the detection result of the detection head 7.
