Both are used to circulate the oil in quick-connect interface 13 and quick-connect interface 214. One end of valve 10 is connected to the pipeline between valve 5, valve 3, and valve 7, and the other end is connected to sampling port 15. One end of valve 11 is connected to the pipeline between valve 6, valve 4, and valve 9, and the other end is connected to sampling port 2 16.

[0020] When using this utility model, the quick interface 13 can be connected to the loading port of the oil tanker, and the quick interface 14 can be connected to the unloading port of the oil tanker. Then, water cutting operations can be performed using input pipe 1, circulation pipe 1, input pipe 2, and circulation pipe 2, and circulation operations can be performed using circulation pipe 3 and circulation pipe 4. By circulating the oil in the oil tanker through water cutting and circulation operations, the oil samples taken are more representative and the detection accuracy is improved.

[0021] In one specific embodiment, the glass inspection container 22 is equipped with a conductivity testing element 23. In this embodiment, in addition to visually inspecting the oil quality in the glass inspection container 22, the conductivity of the oil can be tested using the conductivity testing element 23 to determine whether the oil contains water. It should be noted that the conductivity testing element 23 is prior art, and its specific structure will not be described in detail here.

[0022] In one specific embodiment, a backlight panel 21 is also included to provide a light source for the glass inspection tank 22. In this embodiment, the backlight panel 21 facilitates visual inspection of oil products in dimly lit environments. Optionally, the backlight panel 21 is an explosion-proof backlight panel. It should be noted that both the backlight panel 21 and the explosion-proof backlight panel are existing technologies, and their specific structures will not be described in detail here.

[0023] In one specific embodiment, a drain valve 19 is also included. One end of the drain valve 19 is connected to the glass inspection tank 22, and the other end is connected to the drain outlet 20, forming a drain pipe. In this embodiment, by setting up a drain pipe, contaminated oil can be discharged when it is detected, ensuring that only clean oil is stored in the tanker truck.

[0024] In one specific embodiment, the circulation pump 24 is an explosion-proof electric circulation pump, and the output end of the circulation pump 24 is also equipped with a flow meter 25 and a pressure sensor 26.

[0025] In one specific embodiment, when the glass inspection container 22 is a sealed container, the oil tanker sampling device further includes valve twelve 12, one end of which is connected to the glass inspection container 22 and the other end is connected to the oil tanker oil and gas recovery port 17, forming a pressure balance protection pipeline.

[0026] In the above embodiments, the present invention can achieve closed sampling, avoid pollution of oil by air, and also avoid safety accidents caused by open flames.

[0027] In one specific embodiment, a pipeline flame arrester 18 is further provided between valve 12 and the glass inspection tank 22, and valves 1 to 12 are electric ball valves. It should be noted that the pipeline flame arrester 18 and the electric ball valve are existing technologies, and their specific structures will not be described in detail here.

[0028] In one specific embodiment, the tanker truck sampling device further includes a control system (not shown in the figure) connected to each valve and the circulating pump 24 respectively. In this embodiment, by adding a control system to control each valve and the delivery pump, sampling can be performed automatically, reducing labor intensity and improving work efficiency. It should be noted that the control system for automatically controlling the valves and the delivery pump is prior art, and its specific structure will not be described in detail here.

[0029] Additionally, it should be noted that the oil tanker sampling device described in this utility model needs to be grounded to prevent the oil from igniting or exploding due to static electricity during circulation and sampling.

[0030] In one specific embodiment, the following is adopted: Figure 1 The sampling device shown in the diagram operates by including the following steps: (1) Water cutting operation After connecting the loading / unloading port and the oil / gas recovery port, start the water cut-off procedure. At this time, valves 5, 3, 8, and 12 are opened, the backlight panel 21 is turned on, and the oil flows into the glass inspection tank 22 through quick-connect interface 13. When the oil reaches the set height of the glass inspection tank 22, valves 3, 8, and 12 are closed. The cleanliness and water content of the oil are checked visually and by the built-in conductivity testing element 23. After the check is completed, the oil is circulated back. Specifically, valves 9, 4, 1, and 12 are opened in sequence, and then the circulation pump 24 is started to transport the oil in the glass inspection tank 22 back to quick-connect interface 13. After the transportation is completed, all the above valves are closed.

[0031] Initiate the second water-cutting procedure. At this time, valves 6, 4, 8, and 12 open sequentially, the backlight panel 21 turns on, and the oil enters the glass inspection tank 22 via quick-connect interface 24. When the oil level reaches the set height of the glass inspection tank 22, valves 4, 8, and 12 close completely. Check the cleanliness and water content of the oil by visual inspection and the built-in conductivity testing element 23. After the inspection is completed, perform a circulation return. Specifically, valves 7, 3, and 2 open sequentially, and the circulation pump 24 starts to transport the oil in the glass inspection tank 22 back to quick-connect interface 24. After the transportation is completed, close all valves.

[0032] (2) Cyclic operation After the initial inspection of the oil products is passed, the cyclic operation procedure is started. You can choose either Cycle 1 or Cycle 2. Cycle 1 refers to the cycle process of extracting oil from quick interface 13 and returning it to the tanker truck from quick interface 2 14. Cycle 2 refers to the cycle process of extracting oil from quick interface 2 14 and returning it to the tanker truck from quick interface 13.

[0033] When cycle one is selected, valves 5, 3, 2, and 6 open sequentially, and then circulation pump 24 starts. At this time, observe the readings of flow meter 25 and pressure sensor 26 to see if they are normal. If the data from pressure sensor 26 exceeds the safety setting value, it indicates that the flow at the outlet of circulation pump 24 is blocked or the tanker truck's bottom valve is not open. If the reading of flow meter 25 is lower than the normal value, it also indicates that the flow is blocked or the tanker truck's bottom valve is not open. Once all readings are normal and the cycle reaches the predetermined cumulative amount, the cycle ends, circulation pump 24 is turned off, and valves 3 and 2 are closed before entering the sampling procedure. The principle is the same when cycle two is selected.

[0034] (3) Sampling operation Connect the two sampling bottles to sampling port 15 and sampling port 26 respectively, open valve 10 or valve 11 to release the sample, and close valve 10 or valve 11 after the cumulative amount of the sample reaches the set amount. The sampling ends.

[0035] In the above embodiments, this utility model avoids working at heights and achieves closed sampling from the perspectives of safety and environmental protection; through water cutting and circulation operations, the samples taken are more representative and the accuracy of detection is improved.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
