Description

Technical Field

[0001] The utility model belongs to the technical field of oil product detection, in particular to a device for detecting water content in oil products loaded on a tank truck. Background Art

[0002] In the oil transportation industry, tank trucks are the main means of transportation. The quality of the oil they carry is directly related to the user's usage effect, the operating safety of the equipment, and environmental protection requirements. Among them, the water content of the oil is an important quality indicator. Excessive water content will not only reduce the combustion efficiency of the oil and increase transportation costs, but may also cause corrosion to the equipment and lead to safety accidents.

[0003] Most existing detection devices are similar to a crude oil water content flowmeter (authorization announcement number CN213874517U) and a crude oil water content detection device (authorization announcement number CN219104911U) disclosed in a Chinese patent. In the former, the meter base is fixed to a fixed pipe, while in the latter, the detector is threadedly connected to a connector. They both have the same disadvantage: the former's fixing method makes it difficult to disassemble the flowmeter head, while the latter requires tools to tighten the detector. Both have the problem of inconvenient rapid disassembly and assembly of the detector, and the latter's threaded connection method has low sealing performance and the risk of oil leakage.

[0021] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0022] See also Figure 1 、 Figure 2 and Figure 3 In an embodiment of the present invention, a device for detecting the water content of oil loaded on a tank truck includes a first tube body 1. Flanges 2 are installed at both front and rear ends of the first tube body 1, and a second tube body 3 is installed on the upper surface of the first tube body 1. The interior of the first tube body 1 is connected to the interior of the second tube body 3. A tube cover 4 is installed at the upper end of the second tube body 3. A water detector body 5 is installed on the upper surface of the tube cover 4. A detection probe 6 is installed at the lower end of the water detector body 5. The detection probe 6 passes through the second tube body 3 and is located inside the first tube body 1.

[0023] One end of the first tube body 1 can be connected to the oil delivery pipe 18 , and the other end can be connected to the oil delivery connector 20 on the tank truck 19 .

[0024] The water detector body 5 is electrically connected to the external control system. The detection probe 6 is used to detect the oil flowing through the first tube 1 to determine whether it contains water. When water is detected, the external control system issues an alarm.

[0025] The water detector body 5 and the detection probe 6 are preferably radio frequency admittance oil water analysis devices, and a capacitor is formed between the probe and the oil pipeline, in which the probe and the pipe wall serve as the positive and negative poles of the capacitor respectively. When the water content in the oil increases, its overall dielectric constant will increase, thereby causing the capacitance value to increase. Conversely, when the water content decreases, the dielectric constant and capacitance value will also decrease accordingly; by analyzing the changes in these capacitance values, the water content in the oil can be accurately calculated.

[0026] exist Figure 1 and Figure 2Middle: The upper surface of the tube cover 4 is located on the lower side of the water detector body 5 and is provided with a countersunk hole 7. The lower surface of the water detector body 5 is located outside the detection probe 6 and is installed with a first sealing ring 8. The first sealing ring 8 is located inside the countersunk hole 7. The lower surface of the first sealing ring 8 is installed with a second sealing ring 9. The second sealing ring 9 is located outside the detection probe 6 and the second sealing ring 9 can move through the tube cover 4.

[0027] The first sealing ring 8 and the second sealing ring 9 are preferably made of rubber material to play a sealing role and prevent oil leakage.

[0028] exist Figures 1 to 3 Middle: The upper surface of the pipe cover 4 is located on the left and right sides of the water detector body 5, and a positioning mechanism 10 is provided. The positioning mechanism 10 includes a horizontal plate 11 and a vertical plate 12 integrally formed with the horizontal plate 11. The horizontal plate 11 is installed on the upper surface of the pipe cover 4, and a telescopic cylinder 13 is installed on the left surface of the vertical plate 12. A moving block 14 is installed at the telescopic end of the telescopic cylinder 13. The moving block 14 is slidably connected to the upper surface of the horizontal plate 11. The upper surface of the horizontal plate 11 is located on one side of the vertical plate 12 and is rotatably connected to a connecting seat 15. The interior of the connecting seat 15 is rotatably connected to a positioning rod 16. The end of the positioning rod 16 away from the moving block 14 is attached to the water detector body 5, and the end of the positioning rod 16 close to the moving block 14 is rotatably connected to a roller rod 17.

[0029] The telescopic cylinder 13 is preferably electric. When it is extended, the moving block 14 pushes the roller 17, and one end of the positioning rod 16 presses the water detector body so that it fits firmly on the pipe cover 4.

[0030] When the water content detector body 5 needs to be disassembled, the telescopic cylinder 13 is first retracted, and then the connecting seat 15 is rotated to drive the positioning rod 16 to stagger the water content detector body 5.

[0031] The working principle of this utility model is:

[0032] During use, the oil delivery pipe 18 is connected to one end of the first tube body 1, and the other end of the first tube body 1 is connected to the oil delivery connector 20. The oil can then be input into the interior of the tank truck 19 through the oil delivery pipe 18, the first tube body 1, and the oil delivery connector 20. The detection probe performs real-time detection on the oil. When water is detected, the water detector body 5 transmits a signal to the external control system. The external control system issues an alarm, and the staff will stop delivering oil. After long-term use, the detection probe needs to be cleaned. First, retract the telescopic cylinder 13, and then rotate the connecting seat 15 so that the positioning rod 16 is offset from the water detector body 5. At this time, the water detector body 5 can be directly pulled out, thereby pulling out the detection probe 6.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
