DETAILED DESCRIPTION

[0025] In order to better understand the above technical solutions, the exemplary embodiments of the utility model will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a clearer and more thorough understanding of the utility model and to enable the scope of the utility model to be fully conveyed to those skilled in the art.

[0026] Embodiment:

[0027] The embodiment of the utility model provides a kind of vehicle-mounted water measuring device of pipeline oiling truck, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 And Figure 6As shown, it comprises: a transparent sampling tube 1; an oil sample container 2 arranged on the transparent sampling tube 1 and connected with the transparent sampling tube 1; an oil delivery pipe 3 arranged through the oil sample container 2; a shaft coupling 4 sleeved on the oil delivery pipe 3 and arranged inside the oil sample container 2; a sealing ring 5 sleeved on the shaft coupling 4 and connected with the inner wall of the oil sample container 2, and the area enclosed between the oil delivery pipe 3, the shaft coupling 4, the sealing ring 5 and the oil sample container 2 forms an oil sample storage cavity; a diaphragm loading part 6 arranged on the oil sample container 2; an oil inlet hole 7 arranged at the bottom of the diaphragm loading part 6 and connected with the oil sample storage cavity; an oil suction pipe 9 connected with the diaphragm inside the diaphragm loading part 6 and passing through the diaphragm loading part 6 and the oil sample container 2 and then connected with the transparent sampling tube 1; and a vacuum pump connecting part 8 arranged below the transparent sampling tube 1, connected with the transparent sampling tube 1 and connected with an external vacuum pump.

[0028] Exemplarily, the on-board water detection device of the pipeline refueling vehicle of the embodiment extracts oil through the externally connected vacuum pump, so that the oil enters the oil sample storage cavity in the oil sample container 2 through the oil delivery pipe 3, the oil in the oil sample storage cavity contacts the diaphragm fixed in the diaphragm loading part 6 through the oil inlet hole 7, and the oil passing through the diaphragm enters the transparent sampling tube 1 through the oil suction pipe 9. Since the shaft coupling 4 and the sealing ring 5 are arranged on the oil delivery pipe 3, the oil sample container 2 can rotate around the oil delivery pipe 3, and after rotation, the transparent upper cover 10 faces the detector, which is convenient for the detector to observe the water detection state of the diaphragm through the transparent upper cover 10 and is also conducive to opening the transparent upper cover 10 to replace the diaphragm. After the detection is completed, the oil in the transparent sampling tube 1 is discharged to the recovery tank.

[0029] Exemplarily, two oil delivery holes 31 can be arranged on the oil delivery pipe 3 inside the oil sample storage cavity, thereby increasing the oil delivery rate of the oil delivery pipe 3 in the oil sample storage cavity and improving the efficiency of water detection.

[0030] Exemplarily, a check valve is arranged inside the oil inlet hole 7 in the embodiment, which avoids the backflow of the oil flowing out of the oil sample storage cavity back into the oil sample storage cavity, thereby preventing the pollution of the oil, and this arrangement increases the accuracy of the water detection of the oil.

[0031] Exemplarily, the oil suction pipe 9 in the embodiment is a kind of corrosion-resistant hose, and the size of the oil suction pipe 9 is matched with the diaphragm, which is convenient for connecting with the diaphragm. An oil suction pipe insertion hole 15 is arranged inside the diaphragm loading part 6, which is convenient for the oil suction pipe 9 to pass through the diaphragm loading part 6 through the oil suction pipe insertion hole 15. Similarly, an insertion hole (not shown in the figure) for passing through the oil suction pipe 9 is also arranged inside the oil sample container 2, and the insertion hole inside the oil sample container 2 is arranged outside the oil sample storage cavity, so that the problem of oil sealing is not involved. Moreover, a sealing member is arranged at the connection between the oil suction pipe 9 and the transparent sampling tube 1, which ensures the sealing performance of the transparent sampling tube 1.

[0032] Exemplarily, the transparent sampling tube 1 in the embodiment is marked with a 5mL scale line as needed, which is beneficial for the operator to observe whether the oil liquid in the transparent sampling tube 1 meets the requirements of water detection.

[0033] Exemplarily, the detection process of the vehicle-mounted water detection device of the pipeline oiling vehicle in the embodiment is as follows:

[0034] Step 1, start and oil:

[0035] When water detection needs to be performed, the vacuum pump is started by connecting the vacuum pump connecting piece 8 with an external vacuum pump. The vacuum pump starts to work and forms a negative pressure environment in the transparent sampling tube 1. Due to the pressure difference, the oil liquid passes through the oil conveying pipe 3, the oil conveying hole 31, passes through the diaphragm, and then passes through the oil sampling pipe 9, the diaphragm loading piece 6 and the oil sample container 2, and enters the transparent sampling tube 1 with a 5mL scale line. Compared with the manual oil extraction of the existing art by using a water detector (syringe), this oil extraction method based on the vacuum pump has more stable suction force and higher extraction efficiency.

[0036] Step 2, water detection:

[0037] Open the transparent upper cover 10, install the diaphragm in the diaphragm loading piece 6, rotate the oil sample container 2 around the oil conveying pipe 3, and place the vacuum pump connecting piece 8 above the oil sample container 2. After the vacuum pump extracts enough oil liquid, rotate the vehicle-mounted water detection device of the pipeline oiling vehicle again, and place the transparent upper cover 10 of the diaphragm loading piece 6 towards the operator. Observe whether the diaphragm in the diaphragm loading piece 6 is discolored. After the observation is completed, open the transparent upper cover 10 to remove the diaphragm, and complete the water detection.

[0038] The water detection process in the embodiment is fast and efficient, and can uniformly extract oil liquid, avoiding the technical problems of unstable suction force and insufficient oil sample extraction of the water detector.

[0039] In one possible embodiment, as shown in Figure 2 The number of couplings 4 is two, which are symmetrically arranged in the oil sample container 2.

[0040] Exemplarily, the two couplings 4 are symmetrically arranged in the oil sample container 2, so that when the oil sample container 2 rotates around the oil conveying pipe 3 through the couplings 4, the stress of the two couplings 4 is more uniform, which is beneficial to improve the sealing performance of the oil sample receiving cavity.

[0041] Exemplarily, when the oil flows in the oil sample receiving cavity, the sealing ring 5 is tightly pressed against the surface of the connecting part of the oil sample container 2 under the action of the shaft coupling 4. The sealing ring 5 can maintain good elasticity and sealing effect whether due to thermal expansion and contraction or long-term use. The sealing ring 5 can effectively prevent oil from leaking from the connecting part. Compared with the rubber ring sealing of the prior art, the sealing effect of the shaft coupling 4 and the sealing ring 5 in the embodiment is more durable and reliable, and the safety hazard caused by oil leakage due to poor sealing effect is avoided.

[0042] In a possible embodiment, as shown in Figure 1 , Figure 5 and Figure 6 , the diaphragm box 14 is arranged on the oil sample container 2; and the transparent upper cover 10 is arranged on the diaphragm box 14 and rotationally connected with one side of the diaphragm box 14.

[0043] Exemplarily, the edge of the connection between the transparent upper cover 10 and the diaphragm box 14 in the embodiment is provided with a sealing material, such as a sealing rubber strip, so as to ensure the sealing performance of the diaphragm loading part 6 when the transparent upper cover 10 and the diaphragm box 14 are closed.

[0044] In a possible embodiment, as shown in Figure 3 , Figure 5 and Figure 6 , the diaphragm loading part 6 further comprises a diaphragm fixing part 11 arranged at the bottom of the diaphragm box 14 and around the oil inlet hole 7.

[0045] Exemplarily, the diaphragm fixing part 11 is integrally connected with the diaphragm box 14, and the size is matched with the diaphragm, so as to meet the requirement that the diaphragm is clamped in the diaphragm fixing part 11. On the one hand, the diaphragm is limited and fixed in the diaphragm box 14, and on the other hand, the diaphragm is convenient to replace in each test.

[0046] In a possible embodiment, as shown in Figure 3 , Figure 5 and Figure 6 , the sealing gasket 13 is arranged in the diaphragm fixing part 11 and abuts against the bottom of the diaphragm box 14.

[0047] Exemplarily, the sealing gasket 13 in the embodiment can be a fluorine gasket or a rubber gasket. The sealing gasket 13 is in a circular ring shape, is placed in the diaphragm fixing part 11 and abuts against the inner wall of the diaphragm fixing part 11, avoids the oil inlet hole 7 at the bottom of the diaphragm box 14, and ensures that the oil liquid from the oil sample container 2 passes through the diaphragm through the oil inlet hole 7 to complete the water detection.

[0048] In a possible embodiment, as shown in Figure 5 and Figure 6As shown, the diaphragm loading member 6 further comprises a pressing member 12, which is arranged corresponding to the diaphragm fixing portion 11 and connected with the inner wall of the transparent upper cover 10.

[0049] As shown, the diaphragm loading member 6 further comprises a pressing member 12, which is arranged corresponding to the diaphragm fixing portion 11 and connected with the inner wall of the transparent upper cover 10.

[0050] In a possible embodiment, as shown in Figure 5 and Figure 6 As shown, the number of the pressing members 12 is multiple, and the multiple pressing members 12 are arranged at intervals.

[0051] As shown, the number of the pressing members 12 is multiple, and the multiple pressing members 12 are arranged at intervals.
