[0023] Embodiment 1 like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a vehicle-mounted oil gauge detection system, which is used to be installed in a vehicle, and can be driven directly to a predetermined position of an oil depot to detect the oil gauge of the oil depot. The vehicle-mounted oil gauge detection system mainly includes: a metering tank 200, an oil outlet pipeline 500, a power take-off assembly 700 and a transmission shaft 710. The metering tank 200 is used to be set in the compartment 11 of the vehicle 10 and detect the amount of oil intake. An oil pump 600 is connected to the oil outlet pipeline 500, and the oil outlet pipeline 500 is connected to the metering tank 200 and the oil in the metering tank 200 is pumped out through the oil pump 600. The power take-off assembly 700 is used to be connected to the auxiliary gearbox 13 of the vehicle 10 in transmission, and the transmission shaft 710 connects the power take-off assembly 700 and the oil pump 600, and the power of the auxiliary gearbox 13 is transmitted to the transmission shaft 710 through the power take-off assembly 700, so that the transmission shaft 710 rotates to drive the oil pump 600. Therefore, when the metering tank 200 completes the detection of the oil output of the oil depot, the oil in the metering tank 200 is pumped out by the oil pump 600 powered by the engine of the vehicle 10 .

[0024] By setting the metering tank 200 in the compartment 11 of the vehicle 10, the metering tank 200 can be transported to a predetermined position of the oil depot through the vehicle 10, and the power take-off assembly 700 is connected to the auxiliary gearbox 13 of the vehicle 10, and the power of the auxiliary gearbox 13 is transmitted to the transmission shaft 710 through the power take-off assembly 700, so that the transmission shaft 710 rotates to drive the oil pump 600. The oil pump 600 can make the oil outlet pipeline 500 extract the oil in the metering tank 200, so that the vehicle-mounted oil meter detection system can be used directly on the vehicle 10 when in use, and the oil pump 600 is driven by the power of the engine of the vehicle 10, so that there is no need to connect another power supply, so that it can be applied to various oil depot scenes, making the detection process of the oil meter in the oil depot more convenient.

[0025] like Figure 1 , Figure 2 As shown, further, a perforation is provided on the outer wall of the compartment 11 facing the cab 12 of the vehicle 10, and the oil pump 600 is fixed to the bottom outside the compartment 11 through the pump mounting frame 610, and can be specifically arranged below the chassis of the vehicle 10 between the cab 12 and the compartment 11. The oil outlet pipeline 500 extends from the compartment 11 through the perforation to the outside of the compartment 11 and is connected to the oil pump 600. In this way, when the oil pump 600 is fixed below the chassis, it can be connected to the engine of the vehicle 10 by transmission. The two ends of the transmission shaft 710 are connected to the power take-off assembly 700 and the oil pump 600 by couplings 720 respectively. Therefore, after the power take-off assembly 700 is started, it can be connected to the auxiliary gearbox 13 of the vehicle 10 by transmission, and the auxiliary gearbox 13 is driven by the engine, so that the power of the engine of the vehicle 10 can be used to provide power for the oil pump 600, thereby realizing the oil pumping function.

[0026] like Figure 3 , Figure 4 As shown, in the specific structure, the pump mounting frame 610 includes: a vertical connecting plate 611, a horizontal connecting plate 612 and a reinforcing rib plate 613. The vertical connecting plate 611 can be fixedly connected to the chassis of the vehicle 10 by passing bolts therethrough, the horizontal connecting plate 612 is vertically fixedly arranged at the lower end of the vertical connecting plate 611, and is extended in the horizontal direction, the oil pump 600 is fixedly connected to the horizontal connecting plate 612 by bolts, and the reinforcing rib plate 613 is welded and fixed at the corner of the vertical connecting plate 611 and the horizontal connecting plate 612, so that the structure of the L-shaped bracket formed by the vertical connecting plate 611 and the horizontal connecting plate 612 is more stable. Since there are structures such as the main shaft, the oil tank and the water tank under the chassis of the vehicle 10, the space under the chassis is limited. By setting an L-shaped pump mounting frame 610, a mounting position for the oil pump 600 can be provided in a limited space. The vertical connecting plate 611 can be made of channel steel, and the horizontal connecting plate 612 can also be made of channel steel. The vertical connecting plate 611 and the horizontal connecting plate 612 are welded and fixed, and a supporting plate 614 is protruded in the groove of the horizontal connecting plate 612. An inclined support plate 615 is welded in the groove of the horizontal connecting plate 612. The inclined support plate 615 and the supporting plate 614 are welded, so that the inclined support plate 615 and the supporting plate 614 are connected to form a reinforced structure, thereby increasing the structural strength of the pump mounting frame 610 and making the horizontal connecting plate 612 support the oil pump 600 more stably.

[0027] like Figure 3 , Figure 4As shown, in the specific structure, the couplings 720 at both ends of the transmission shaft 710 are respectively universal couplings 720, and the shaft of the power take-off assembly 700 and the shaft of the oil pump 600 are connected through the universal coupling 720. Even if the two shafts are not on the same axis, when there is an axis angle, the transmission shaft 710 can realize the continuous rotation of the two connected shafts, and reliably transmit torque and motion. The universal coupling 720 has a large angular compensation capability, a compact structure, and high transmission efficiency. The angle between the two axes of the universal coupling 720 can be between 5°-45°. Therefore, after the oil pump 600 is fixed by the pump mounting frame 610, the accuracy of the pump mounting frame 610 is not required. The position of the oil pump 600 is fixed, and the position relationship with the power take-off assembly 700 is fixed. Even if the shaft of the oil pump 600 is not concentric with the shaft of the power take-off assembly 700, it can be connected, so as to facilitate the fixed installation of the oil pump 600.

[0028] In addition, in order to facilitate the distance adjustment between the oil pump 600 and the power take-off assembly 700, the transmission shaft 710 can be a telescopic shaft. When the oil pump 600 is fixed, the length of the transmission shaft 710 is adjusted by telescoping the transmission shaft 710, so that the transmission shaft 710 is fixedly connected to the shaft of the power take-off assembly 700 and the shaft of the oil pump 600 through the universal couplings 720 at both ends, respectively, to achieve stable transmission.

[0029] Furthermore, the power take-off assembly 700 is connected to a power take-off control switch, which is disposed in the cab 12 of the vehicle 10 and is used to control the opening or closing of the transmission of the power take-off assembly 700. The power take-off control switch is disposed on the operation panel of the cab 12 as a function of the vehicle 10, so that the staff can conveniently operate the oil discharge process in the cab 12.

[0030] like Figure 1 , Figure 5 , Figure 6 As shown, further, the metering tank 200 can adopt a capacity of 2000L, and the metering tank 200 is vertically arranged in the carriage 11 through the frame 100, and the metering tank 200 is supported by the frame 100. A main oil pipe 210 is arranged at the bottom of the metering tank 200, and the main oil pipe 210 is arranged at the bottom of the metering tank 200, and an oil inlet 211 is opened at the end for docking with the oil pipeline of the oil depot. The oil is transported from the bottom to the metering tank 200 through the oil inlet 211 through the oil pipeline of the oil depot. The actual delivery volume of the oil depot is measured by the metering tank 200, and compared with the displayed delivery volume of the oil meter of the oil depot, so as to realize the detection of the oil meter.

[0031] The rack 100 of this embodiment specifically includes a main support frame 110, which is connected to the bottom edge of the metering tank 200 and lifts the metering tank 200 to form a pipeline installation space 101. In the specific structure, the main support frame 110 may include four columns or multiple columns of other numbers, the lower parts of the four columns are cross-welded and fixed by steel plates, and the tops of the four columns can be welded and fixed to the metering tank 200. The four columns surround the pipeline installation space 101, which is convenient for the installation of various pipelines.

[0032] like Figure 6 , Figure 7 , Figure 8 As shown, further, in this embodiment, the main oil pipe 210 is provided with a main channel valve 220, and the oil inlet 211 is provided with an oil pipe joint 230, and the main oil pipe 210 is detachably connected to the oil pipeline of the oil depot through the oil pipe joint 230. The main oil pipe 210 is provided with a joint, which is convenient for docking with the oil pipeline of the oil depot, and the joint matches the oil pipeline port, which is convenient for disassembly. After the oil inlet 211 of the main oil pipe 210 is docked with the oil pipeline of the oil depot, the main channel valve 220 is opened to achieve the connection between the oil pipeline and the metering tank 200. Thereby, the oil depot can deliver oil to the metering tank 200.

[0033] like Figure 6 , Figure 7 , Figure 8 As shown, further, one end of the main oil pipe 210 of this embodiment is connected to the center of the bottom of the metering tank 200, and the other end extends downwardly at an angle. The main oil pipe 210 is located at the bottom of the metering tank 200 and extends to the outside of the pipe installation space 101 of the frame 100, so that the oil pipeline is conveniently connected to the main oil pipe 210 outside the frame 100, and the disassembly and assembly are more convenient. In addition, the main oil pipe 210 is tilted downward, so that the oil in the metering tank 200 can be discharged cleanly during the oil discharge process, and the oil residue in the metering tank 200 can be minimized.

[0034] like Figure 6 , Figure 8 As shown, further, a support rod 240 is fixedly provided at the bottom of the metering tank 200 of this embodiment, and the support rod 240 is fixedly connected to the main oil pipe 210. Since the main oil pipe 210 extends from the middle of the bottom of the metering tank 200 toward the outside, the main oil pipe 210 is fixedly connected by the support rod 240, thereby improving the structural strength of the main oil pipe 210, so that the main oil pipe 210 is more stable when it is in an inclined suspension state.

[0035] like Figure 5 , Figure 7As shown, further, the vehicle-mounted oil gauge detection system also includes: an oil and gas recovery pipe 300, which is arranged on the upper part of the metering tank 200 and is used to connect with the oil and gas recovery pipe of the oil depot. When testing the oil gauge, when 2000 liters of oil are added to the standard metering tank 200, 2000 liters of air are also discharged. The oil and gas recovery pipe 300 is connected to the oil and gas recovery processing device of the oil depot through the top connection, which reduces the exhaust gas emission, so that the oil and gas in the metering tank 200 can enter the oil and gas recovery pipe of the oil depot from the top of the metering tank 200, and recover the oil and gas, so as to prevent the oil and gas from entering the air and prevent environmental impact.

[0036] like Figure 5 , Figure 6 , Figure 7 As shown, further, the top of the metering tank 200 of this embodiment is sealed, so an air outlet pipe 250 is arranged on its upper part, and an oil and gas joint 310 is arranged on the frame 100. The oil and gas joint 310 is used to be detachably connected with the oil and gas recovery pipe of the oil depot, and one end of the oil and gas recovery pipe 300 is fixedly connected to the air outlet pipe 250, and the other end is connected to the oil and gas joint 310. In the specific structure, the air outlet pipe 250 is radially arranged on the outer wall of the upper part of the metering tank 200, and one end of the oil and gas recovery pipe 300 is sleeved on the air outlet pipe 250 and is locked and fixed by a clamp. The oil and gas recovery pipe 300 can be a spring silicone tube, which can be extended along the outer wall of the metering tank 200, and the other end extends below the metering tank 200 and is fixed to the oil and gas joint 310 by a clamp. The oil and gas joint 310 located below is convenient for detachable connection with the recovery oil and gas pipe, so that the oil and gas in the metering tank 200 can be recovered to the oil depot, avoiding the impact on the environment.

[0037] like Figure 6 , Figure 7 , Figure 8 As shown, further, the frame 100 of this embodiment also includes: a first connecting frame 120, the first connecting frame 120 is arranged on the main support frame 110 and is located below the metering tank 200, and the oil and gas joint 310 is fixedly arranged on the first connecting frame 120. In the specific structure, the oil and gas joint 310 is fixed by the first connecting frame 120, so that the oil and gas joint 310 is stably fixed below the metering tank 200, thereby facilitating the loading and unloading of the recovered oil and gas pipe of the oil depot. The first connecting frame 120 can be a tripod, one end of the tripod is welded to the column of the main support frame 110, and the other end is fixed to the oil and gas joint 310 by a clamp.

[0038] like Figure 6 , Figure 7 , Figure 8As shown, further, the vehicle-mounted oil gauge detection system of this embodiment also includes: an anti-static connector 400, which is electrically connected to the metering tank 200 and is used to be detachably connected to the anti-static controller of the oil depot. By setting the anti-static connector 400, which matches the electrostatic interface of the oil depot, static electricity is released, and safety accidents caused by static electricity are eliminated. The static electricity on the detection vehicle is released through the oil depot electrostatic system, and the static electricity on the metering tank 200 is eliminated through the anti-static connector 400, so that safe operation can be achieved, and the oil depot oil delivery system can deliver oil normally, ensuring the safety of the detection area.

[0039] like Figure 6 , Figure 7 , Figure 8 As shown, further, the rack 100 of this embodiment also includes: a second connecting frame 130, the second connecting frame 130 is arranged on the main support frame 110 and is located outside the pipeline installation space 101, and the anti-static connector 400 is fixedly arranged on the second connecting frame 130. In the specific structure, the second connecting frame 130 can adopt a bending plate, and the side of the bending plate faces the outside of the pipeline installation space 101. The anti-static connector 400 is fixed on the side of the bending plate. The anti-static connector 400 is an existing structural standard part, which is mainly used for docking with the anti-static controller of the oil depot. The anti-static controller of the oil depot is also an existing structure, such as an existing oil depot anti-overflow anti-static controller.

[0040] like Figure 6 , Figure 7 , Figure 8 As shown, further, the anti-static connector 400 of this embodiment is connected with a first electrostatic conduction line 410 and a second electrostatic conduction line 420, the first electrostatic conduction line 410 extends from the top of the metering tank 200 to the inside of the metering tank 200; the second electrostatic conduction line 420 is connected to the main support frame 110. The first electrostatic conduction line 410 extends from the top of the metering tank 200 to the inner cavity of the metering tank 200 to eliminate the static electricity generated on the metering tank 200. The second electrostatic conduction line 420 is connected to the main support frame 110 or the bending plate to achieve a conductive connection with the frame 100, thereby eliminating the static electricity on the frame 100, avoiding the safety hazards caused by static electricity, and ensuring the safety of the oil gauge detection process.

[0041] like Figure 6 , Figure 7 , Figure 8As shown, further, the oil outlet pipeline 500 of this embodiment can also be arranged at the bottom of the metering tank 200, and the oil outlet pipeline 500 is connected to the oil pump 600. When in use, the oil outlet pipeline 500 is connected to the oil delivery pipe of the tanker to extract the oil in the metering tank 200. The oil outlet pipeline 500 is connected to the bottom of the metering tank 200. After the oil gauge detection is completed, the oil in the metering tank 200 needs to be extracted from the metering tank 200. After the oil outlet pipeline 500 is used to connect with the oil delivery pipe of the tanker, the oil pump 600 is started to extract the oil in the metering tank 200.

[0042] like Figure 3 , Figure 6 , Figure 8 As shown, in the specific structure, the oil outlet pipe 500 includes: a first oil outlet pipe 530 and a second oil outlet pipe 540. One end of the first oil outlet pipe 530 is connected to the main oil pipe 210, and the other end is connected to the liquid inlet of the oil pump 600; one end of the second oil outlet pipe 540 is connected to the liquid outlet of the oil pump 600, and the other end is used to output the oil in the metering tank 200, so as to realize the oil pumping function. The oil outlet pipe 500 is fixedly arranged in the pipeline installation space 101, one end of the first oil outlet pipe 530 is connected to the main oil pipe 210, and the other end extends out of the car 11, which is convenient for docking with the liquid inlet of the oil pump 600; the first end of the second oil outlet pipe 540 is docked with the liquid outlet of the oil pump 600, and the other end extends to the outside of the pipeline installation space 101, which is convenient for docking with the oil pipeline of the tank truck. Moreover, one end of the first oil outlet pipe 530 is connected to the side of the main channel valve 220 facing the metering tank 200. When the main oil pipe 210 needs to be supplied with oil, the main channel valve 220 is opened; when the oil outlet pipe 500 is discharging oil, the main channel valve 220 is closed, so that the oil outlet and oil inlet processes can share the main oil pipe 210, and both the oil inlet and oil outlet processes can be completed from the bottom center of the metering tank 200. Through the control of the main channel valve 220, the main channel can achieve different functions. In this way, it is avoided that the oil residue caused by setting up another pipeline on the metering tank 200 is avoided, and the metering and detection process is more accurate. The first oil outlet valve 510 is arranged on the end of the first oil outlet pipe 530 facing the main oil pipe 210, and the second oil outlet valve 520 is arranged at the outlet end of the second oil outlet pipe 540. In this way, when oil flows into the main oil pipe 210, the first oil outlet valve 510 and the second oil outlet valve 520 are both closed to allow the main oil pipe 210 to flow into oil smoothly; when the oil gauge detection is completed, the main channel valve 220 is closed, the first oil outlet valve 510 and the second oil outlet valve 520 are both opened, and the oil pump 600 is started to drain the oil.

[0043] like Figure 8 , Fig. 9As shown, further, the main oil pipe 210 of this embodiment is tilted downward from the bottom center of the metering tank 200, so as to facilitate liquid delivery and drainage. And the first oil outlet pipe 530 is connected to the main oil pipe 210 and extends tilted downward, so that the oil can be pumped more cleanly during the oil drainage process. In the specific structure, the inclination angle of the main oil pipe 210 and the horizontal plane is the first inclination angle a1, and the inclination angle of the first oil outlet pipe 530 and the horizontal plane is the second inclination angle a2. The second inclination angle a2 is greater than the first inclination angle a1. By adopting a smaller first inclination angle, when the oil pipeline of the oil depot delivers oil, the oil can be made to flow upward along the main oil pipe 210 into the metering tank 200. The inclination angle of the main oil pipe 210 is small, and the pipe mouth of the main oil pipe 210 is more inclined to face the side inner wall of the metering tank 200. The side inner wall of the metering tank 200 bears the impact force of the oil when the oil is fed, thereby avoiding the oil entering the metering tank 200 from impacting upward and splashing into the oil and gas recovery pipe 300, causing oil waste and inaccurate measurement. The second inclination angle is set to be relatively large. During the oil pumping process, under the action of the suction force of the oil pump 600, the oil at the bottom of the metering tank 200 and the main oil pipe 210 can flow along a larger inclination angle, thereby avoiding oil residue on the inner wall. In this way, in the subsequent detection process, the capacity of the metering tank 200 can be guaranteed to be basically the standard capacity, ensuring the accuracy of the metering measurement.

[0044] In addition, before the oil meter of the oil depot is detected, when the main channel valve 220 on the main oil pipe 210 is closed, the oil pump 600 can be started to detect whether there is oil residue in the metering tank 200 and the main oil pipe 210. If there is oil residue, the oil is drained through the oil outlet pipe 500. By adopting a smaller first inclination angle, the side of the main oil pipe 210 that closes the main channel valve 220 will not be tilted too steeply, so that the residual oil in the main oil pipe 210 from the first oil outlet pipe 530 to the main channel valve 220 can be easily extracted, so that the residual oil in the entire metering tank 200 is avoided to ensure the accuracy of the detection.

[0045] Therefore, by tilting the first oil outlet pipe 530 and the main oil pipe 210 to each other, the functions of oil inlet and oil outlet are realized, while ensuring the smoothness of the oil inlet process and avoiding the residue in the oil outlet process, which plays an important role in the use of the vehicle-mounted oil gauge detection system.

[0046] like Figure 3 , Figure 7As shown, further, a plurality of detection components 800 are arranged on the metering tank 200 of the present embodiment, and the plurality of detection components 800 are evenly distributed in a circular shape around the central axis of the metering tank 200. Each detection component 800 includes: a visual liquid indicating tube 810 and a measuring member 820, the visual liquid indicating tube 810 is connected to the metering tank 200 in the up-down direction, and the measuring member 820 is located on one side of the visual liquid indicating tube 810 and is used to measure the liquid level in the visual liquid indicating tube 810. Three detection components 800 of the present embodiment can be arranged, and adjacent detection components 800 are distributed on the top of the metering tank 200 at intervals of 120°. When the liquid level is in the visual liquid indicating tube 810, the corresponding oil volume value can be read according to the liquid level. Because the parking position of the vehicle 10 may be a non-horizontal plane, the liquid level heights detected in the three directions are different, and the oil volume values ​​measured by the plurality of detection components 800 are averaged to obtain the actual oil output this time.

[0047] In this embodiment, a temperature sensor 260 is also provided on the main oil pipe 210, and a temperature sensor 260 is also provided on the metering tank 200. The temperature sensor 260 can detect the temperature of the oil delivered from the oil depot, and the actual oil output can be corrected according to the influence of the temperature on the oil volume, so that the detection of the actual oil output is more accurate.

[0048] Embodiment 2 This embodiment is a measurement and detection vehicle, such as Figure 1 , Figure 2 As shown, it includes a vehicle 10 and the vehicle-mounted oil gauge detection system as described above, and the vehicle-mounted oil gauge detection system is arranged on the vehicle 10. The metering tank 200 is arranged in the carriage 11, and the oil gauge of the oil depot can be measured and detected by just opening the carriage door.

[0049] Embodiment 3 This embodiment provides a fuel gauge detection method, which is applied to the vehicle-mounted fuel gauge detection system as described above. The fuel gauge detection method includes the following steps: Step S100, open the carriage, connect the oil pipeline of the oil depot with the main oil pipeline on the metering tank, connect the oil and gas recovery pipe of the oil depot with the oil and gas recovery pipe on the metering tank, and connect the anti-static controller of the oil depot with the anti-static connector.

[0050] When the main channel valve on the main oil pipe is closed, the oil pump can be started to detect whether there is oil residue in the metering tank and the main oil pipe. If there is oil residue, the oil will be drained through the oil outlet pipe.

[0051] After making sure that the residual oil has been drained, turn off the oil pump, close the first oil outlet valve and the second oil outlet valve, and open the main channel valve to allow the oil depot to drain the oil normally, and transport the oil to the main oil pipeline of the metering tank through the oil pipeline and enter the metering tank.

[0052] Step S200: read multiple measurement values ​​through multiple detection components on the metering tank, and obtain the actual oil output by taking the average value of the multiple measurement values.

[0053] In the specific process, when the liquid level is within the visible liquid indicator tube, the corresponding oil volume value can be read according to the liquid level height. If the vehicle is parked on a non-horizontal surface, the liquid level heights detected by the detection components in multiple directions are different. The oil volume values ​​measured by multiple detection components are averaged to obtain the actual oil output.

[0054] Step S300: Compare the actual oil output with the oil output displayed on the oil gauge to determine whether the oil gauge is qualified.

[0055] Step S400, start the power take-off assembly, and transmit the power of the auxiliary gearbox to the oil pump through the power take-off assembly to pump out the oil in the metering tank through the oil outlet pipeline.

[0056] In summary, the vehicle-mounted oil gauge detection system, metering detection vehicle and oil gauge detection method proposed in this application, by setting the metering tank in the vehicle compartment, the metering tank can be transported to the predetermined position of the oil depot by the vehicle, and the power take-off assembly is connected to the auxiliary gearbox of the vehicle through the power take-off assembly, and the power of the auxiliary gearbox is transmitted to the transmission shaft through the power take-off assembly, so that the transmission shaft rotates and drives the oil pump. The oil pump can make the oil outlet pipeline extract the oil in the metering tank, so that the vehicle-mounted oil gauge detection system can be used directly on the vehicle when in use, and the oil pump is driven by the power of the vehicle's engine, so that there is no need to connect to a power supply separately, so that it can be applied to various oil depot scenes, making the oil meter detection process of the oil depot more convenient. An oil and gas recovery pipe is set on the upper part of the metering tank, and the oil and gas recovery pipe is connected to the oil and gas recovery pipe of the oil depot; when the oil meter is detected, the oil and gas input into the metering tank can enter the oil and gas recovery pipe of the oil depot from the top of the metering tank to recover the oil and gas, so as to avoid the oil and gas from entering the air and prevent environmental impact. Furthermore, by providing an anti-static connector, the anti-static connector eliminates static electricity on the metering tank, thereby ensuring the safety of the detection area.
