DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, a diesel pour point determination device comprises a box body 1, a refrigerator 2 is arranged inside the box body 1, a refrigeration hole is opened on the refrigerator 2, a fixing plate 3 is arranged on the upper surface of the box body 1, a slide rail 4 is arranged on one side of the fixing plate 3, a mounting plate 5 is slidably connected to the slide rail 4, a temperature detector 6 is arranged on one side of the mounting plate 5, a placement port 7 is arranged at the lower end of the temperature detector 6, and a test tube 8 is also included, the test tube 8 is fixed to the lower end of the temperature detector 6 through the placement port 7, a guide plate 9 is arranged on the other side of the mounting plate 5, the guide plate 9 and the temperature detector 6 are fixedly connected through a round rod 10, and the round rod 10 is rotatably connected to the mounting plate 5, A guide rod 11 is provided on one side of the guide plate 9 close to the fixed plate 3, a guide groove 12 is provided on the outer surface of one side of the fixed plate 3, the guide groove 12 includes a vertical area and an inclined area, the inclined area is located above the vertical area, a mounting groove is provided on the box body 1, an electric telescopic rod 13 is provided in the mounting groove, a connecting plate 14 is provided at the output end of the electric telescopic rod 13, the connecting plate 14 is fixedly connected to the mounting plate 5, a photographing device 15 is provided on one side of the fixed plate 3, a processing device 16 is also provided on the box body 1, the processing device 16 has a display screen, and the refrigerator 2, the temperature detector 6, and the photographing device 15 are all electrically connected to the processing device 16.

[0019] The refrigerator 2 includes at least one compressor unit. After a certain amount of diesel is loaded into the test tube 8, the test tube 8 is placed in a refrigeration cavity. The refrigerator 2 controls the temperature of the test tube 8 and the diesel in the test tube 8 through the refrigeration cavity. According to the different temperatures required for the test, the temperature of the test tube 8 and the diesel in the test tube 8 is gradually reduced, thereby achieving the purpose of testing the pour point of diesel.

[0020] The temperature detector 6 is used to detect the temperature of the test tube 8. The test tube 8 is made of transparent material, which is convenient for observing the flow of diesel in the test tube 8. The temperature of the test tube 8 is close to the temperature of the diesel, and the temperature error is within the allowable range of the test. The temperature of the diesel can be obtained by measuring the temperature of the test tube 8. When the temperature of the test tube 8 stably reaches a certain value, such as 0°C, the temperature of the diesel in the test tube 8 can also be considered to be 0°C, with an error of less than ±0.2°C. When it is stable at this temperature, the test tube 8 can be taken out of the refrigeration cavity and used to test the pour point of the diesel at this temperature.

[0021] When the output end of the electric telescopic rod 13 is extended, the mounting plate 5 is driven to move upward along the slide rail 4 through the connecting plate 14. During the upward movement of the mounting plate 5, the temperature detector 6 and the test tube 8 on one side of the mounting plate 5 are driven to move upward, and the guide plate 9 and the guide rod 11 are also driven to move upward. When the test tube 8 is completely out of the refrigeration hole, the guide rod 11 is still in the vertical area of ​​the guide groove 12. At this time, the test tube 8 is in a vertical state. As the test tube 8 continues to move upward, the guide rod 11 enters the inclined area of ​​the guide groove 12 from the vertical area of ​​the guide groove 12. When the guide rod 11 enters the inclined area of ​​the guide groove 12, the temperature detector 6 is driven to tilt through the guide plate 9 and the round rod 10. When the guide rod 11 reaches the top of the inclined area in the guide groove 12, the overall inclination angle of the test tube 8 is 45°. At the same time, the test tube 8 enters the front of the photographing device 15, which is convenient for photographing and sampling by the photographing device 15.

[0022] When the guide rod 11 reaches the top of the inclined area in the guide groove 12, the electric telescopic rod 13 stops working. At this time, the timing is 5s. After 5s, the photographing device 15 takes photos of the test tube 8 for sampling. The taken photos are transmitted to the processing device 16 and can be stored in the processing device 16. At the same time, the photos can also be displayed on the screen of the processing device 16, so that the test personnel can observe the flow of diesel in the test tube 8 after tilting for 5s.

[0023] After the pour point measurement of the diesel at this temperature is completed, the temperature of the diesel in the test tube 8 is gradually lowered in stages, and the pour point of the diesel is measured at different temperatures.

[0024] Furthermore, a docking frame 17 is provided on the upper surface of the box body 1 and above the refrigeration hole. A cleaning block 18 is provided inside the docking frame 17. A through hole is opened in the middle of the cleaning block 18. When the temperature detector 6 moves downward, it can abut against the upper end of the docking frame 17 and close the upper end of the docking frame 17 to reduce temperature loss. When the test tube 8 leaves the refrigeration hole, the cleaning block 18 in the docking frame 17 can wipe the fog on the outer surface of the test tube 8 to prevent the camera 15 from being unable to take clear photos.

[0025] Furthermore, the guide rod 11 is rotatably connected to the guide plate 9, which can reduce the friction between the guide rod 11 and the guide groove 12 and improve the stability of the operation of the device.

[0026] Furthermore, a baffle 19 is provided on one side of the photographing device 15. Through the baffle 19, the background of each photograph taken by the photographing device 15 can be the same, which is convenient for later information collection.

[0027] Furthermore, a level line 20 is provided on the inner side surface of the baffle 19 , and the level line 20 facilitates the subsequent recording and comparison of the inclination angle of the diesel in the test tube 8 .

[0028] The device can automatically rotate the test tube 8 to a suitable tilt angle after lifting it from the refrigeration cavity, and then collect and record information through the camera 15. Compared with the traditional manual method, it is not only more efficient, but also more stable in the test process. The cleaning block 18 can also eliminate the fog on the outer wall of the test tube 8, ensuring the recording effect of the camera 15 and good use effect.

[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
