Abstract
Description
Technical Field
[0001] This application relates to the field of oil depot oil meter detection technology, and more specifically, to an oil flow metering device with oil and gas recovery function and a metering and testing vehicle. Background Technology
[0002] Oil flow meters (or oil gauges) in oil depots need to be periodically tested to ensure that their errors during refueling are within acceptable limits. Weighing or volumetric comparison methods are commonly used to test these instruments. A traditional testing method involves using a standard metering tank as a container, supplying oil from the oil depot's pipeline into the standard metering tank, measuring the actual flow rate through the tank, and comparing this measurement with the flow rate displayed on the oil depot's meter. This allows for the determination of the flow meter's indication error, which is then adjusted accordingly.
[0003] Existing standard metering tanks typically only have a metering function. During the testing process, oil vapors generated from the oil will overflow directly from the top of the standard metering tank. In the confined space and without anti-static protection, this not only pollutes the environment but also poses a significant safety hazard.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content
[0005] The purpose of this application is to provide a metering device with oil and gas recovery function for detecting oil flow meters in oil depots, as well as a metering and testing vehicle, which solves the shortcomings of the prior art in using metering tanks for oil meter detection, which causes environmental impact and safety hazards due to oil and gas overflow.

[0039] Example 1
[0040] like Figure 1 , Figure 2As shown, this embodiment proposes an oil flow metering device with oil and gas recovery function, mainly including: a frame 100, a metering tank 200, an oil inlet 211, an oil and gas recovery pipe 300, and an anti-static connector 400. The frame 100 is vertically arranged, and the metering tank 200 is mounted on the frame 100, supported by the frame 100. The metering tank 200 is used to detect the oil intake. The oil inlet 211 is located at the bottom of the metering tank 200 and is used to connect to the oil supply pipe of the oil depot. Oil is transported from the bottom to the metering tank 200 through the oil supply pipe of the oil depot via the oil inlet 211. The metering tank 200 measures the actual delivery volume of the oil depot and compares it with the displayed delivery volume of the oil meter (oil flow meter) of the oil depot, thereby realizing the detection of the oil meter (oil flow meter). The upper part of the metering tank 200 is sealed, and the oil vapor recovery pipe 300 is located at the upper part of the metering tank 200 and is used to connect with the oil vapor recovery pipe of the oil depot. After the oil enters the metering tank 200 from the bottom, the evaporated oil vapor is concentrated at the upper part of the metering tank 200 and is drawn to the oil vapor recovery pipe of the oil depot through the oil vapor recovery pipe 300, thereby recovering the oil vapor. The anti-static connector 400 is electrically connected to the metering tank 200 and is used for detachable connection with the anti-static controller of the oil depot. During testing, after connecting to the anti-static controller of the oil depot through the anti-static connector 400, the anti-static function of the metering tank 200 is realized, and the oil delivery pipe of the oil depot safely delivers oil. The oil vapor recovery and anti-static functions through the oil vapor recovery pipe 300 ensure the safety of oil delivery during the oil meter testing process.
[0041] like Figure 1 , Figure 2 As shown, the oil flow metering device with oil vapor recovery function in this embodiment has an oil inlet 211 at the bottom of the metering tank 200. The inlet 211 is connected to the oil pipeline of the oil depot, allowing the oil transported by the oil pipeline to enter the metering tank 200 for metering and detection. An oil vapor recovery pipe 300 is installed at the top of the metering tank 200 and connected to the oil vapor recovery pipe of the oil depot. When the oil meter is tested, 2000 liters of oil are added to the standard metering tank 200, and 2000 liters of air are simultaneously discharged. This air is connected to the oil vapor recovery treatment device of the oil depot via the top oil vapor recovery pipe 300. This reduces exhaust emissions, allowing the oil vapor in the metering tank 200 to enter the oil vapor recovery pipe of the oil depot from the top of the metering tank 200 for oil vapor recovery, preventing the oil vapor from entering the air and causing environmental impact. Furthermore, by installing an anti-static connector 400 that matches the static electricity interface of the oil depot, static electricity is released, eliminating safety accidents caused by static electricity. This allows the static electricity on the testing vehicle to be released through the oil depot's static electricity system, and the static electricity on the metering tank 200 to be eliminated through the anti-static connector 400, ensuring safe operation and normal oil dispensing by the oil depot's oil dispensing system, thus guaranteeing the safety of the testing area.
[0042] like Figure 2 , Figure 3 , Figure 4 As shown, further, the frame 100 in this embodiment specifically includes a main support frame 110. The main support frame 110 is connected to the bottom edge of the metering tank 200, raising the metering tank 200 to form a pipe installation space 101. Specifically, the main support frame 110 may include four columns or other multiple columns. 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 form the pipe installation space 101, facilitating the installation of various pipes.
[0043] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, a main oil pipe 210 is provided at the bottom of the metering tank 200, connecting the metering tank 200. An oil inlet 211 is located at the end of the main oil pipe 210 away from the metering tank 200. A main channel valve 220 is provided on the main oil pipe 210, and an oil pipe connector 230 is provided on the oil inlet 211. The main oil pipe 210 is detachably connected to the oil depot's pipeline via the oil pipe connector 230. The connector on the main oil pipe 210 facilitates docking with the oil depot's pipeline, and the connector matches the pipeline inlet for easy disassembly. After the oil inlet 211 of the main oil pipe 210 is docked with the oil depot's pipeline, the main channel valve 220 is opened, thereby connecting the oil pipeline to the metering tank 200.
[0044] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, one end of the main oil pipe 210 is connected to the center of the bottom of the metering tank 200, and the other end extends downward at an angle. This positions the main oil pipe 210 at the bottom of the metering tank 200 and extends to the outside of the pipe installation space 101 of the frame 100. This facilitates the connection of the oil delivery pipe to the main oil pipe 210 on the outside of the frame 100, making assembly and disassembly more convenient. Furthermore, by tilting the main oil pipe 210 downward, it is easier to completely drain the oil from the metering tank 200 during the oil discharge process, minimizing oil residue in the metering tank 200.
[0045] like Figure 2 , Figure 4 As shown, in this embodiment, a support rod 240 is fixedly installed at the bottom of the metering tank 200, 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 outward, the support rod 240 fixes the main oil pipe 210, thereby improving the structural strength of the main oil pipe 210 and making the main oil pipe 210 more stable when it is in an inclined suspended state.
[0046] like Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, the upper part of the metering tank 200 is provided with an exhaust pipe 250, and the frame 100 is provided with an oil-gas connector 310. The oil-gas connector 310 is used for detachable connection with the oil recovery pipe of the oil depot. One end of the oil-gas recovery pipe 300 is fixedly connected to the exhaust pipe 250, and the other end is connected to the oil-gas connector 310. In the specific structure, the exhaust pipe 250 is arranged radially on the outer wall of the upper part of the metering tank 200. One end of the oil-gas recovery pipe 300 is sleeved on the exhaust pipe 250 and locked and fixed by a clamp. The oil-gas recovery pipe 300 can be a spring silicone tube, which can extend along the outer wall of the metering tank 200. The other end extends below the metering tank 200 and is fixed to the oil-gas connector 310 by a clamp. The oil-gas connector 310 located below facilitates detachable connection with the oil recovery pipe, thereby recovering the oil and gas in the metering tank 200 into the oil depot and avoiding environmental impact.
[0047] like Figure 2 , Figure 3 , Figure 4 As shown, the frame 100 in this embodiment further includes a first connecting frame 120, which is disposed on the main support frame 110 and located below the metering tank 200. An oil / gas connector 310 is fixedly disposed on the first connecting frame 120. Specifically, the oil / gas connector 310 is fixed to the first connecting frame 120, ensuring its stable placement below the metering tank 200, thus facilitating loading and unloading with the oil / gas recovery pipe of the oil depot. The first connecting frame 120 can be a tripod, with one end welded to the column of the main support frame 110 and the other end fixed to the oil / gas connector 310 using a clamp.
[0048] like Figure 2 , Figure 3 , Figure 4 As shown, the frame 100 in this embodiment further includes a second connecting frame 130, which is disposed on the main support frame 110 and located on the outside of the pipe installation space 101. An anti-static connector 400 is fixedly disposed on the second connecting frame 130. Specifically, the second connecting frame 130 can be a bent plate, with its side facing the outside of the pipe installation space 101. The anti-static connector 400 is fixed to the side of the bent plate. The anti-static connector 400 is a standard existing component, mainly used for interfacing with the anti-static controller of the oil depot. The anti-static controller of the oil depot is also an existing structure, such as a conventional oil depot anti-overflow anti-static controller.
[0049] like Figure 2 , Figure 3 , Figure 4As shown, in this embodiment, the anti-static connector 400 is further connected to a first static electricity conduction line 410 and a second static electricity conduction line 420. The first static electricity conduction line 410 extends from the top of the metering tank 200 into the interior of the metering tank 200; the second static electricity conduction line 420 is connected to the main support frame 110. The first static electricity conduction line 410 extends from the top of the metering tank 200 into the interior of the metering tank 200 to eliminate static electricity generated on the metering tank 200. The second static electricity conduction line 420 is connected to the main support frame 110 or to a bending plate to achieve a conductive connection with the frame 100, thereby eliminating static electricity on the frame 100, avoiding safety hazards caused by static electricity, and ensuring safety during the oil meter detection process.
[0050] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the bottom of the metering tank 200 is provided with an oil outlet pipe 500, which is connected to an oil pump 600. The oil outlet pipe 500 is used to connect with the oil delivery pipe of the tanker truck. Since the oil outlet pipe 500 is connected to the bottom of the metering tank 200, after the oil meter reading is completed, the oil in the metering tank 200 needs to be extracted. This is done by connecting the oil outlet pipe 500 to the oil delivery pipe of the tanker truck, and then starting the oil pump 600 to extract the oil from the metering tank 200.
[0051] In this embodiment, the oil outlet pipe 500 is fixedly installed within the pipe installation space 101. One end of the oil outlet pipe 500 is connected to the main oil pipe 210, and the other end extends to the outside of the pipe installation space 101, facilitating connection with the oil tanker's pipeline. Furthermore, one end of the oil outlet pipe 500 is connected to the side of the main channel valve 220 facing the metering tank 200, and a first oil outlet valve 510 is installed on this side of the oil outlet pipe 500. A second oil outlet valve 520 is installed at the other end of the oil outlet pipe. Thus, when oil enters the main oil pipe 210, both the first oil outlet valve 510 and the second oil outlet valve 520 are closed, allowing oil to flow smoothly into the main oil pipe 210. After the oil meter reading is completed, the main channel valve 220 is closed, and both the first oil outlet valve 510 and the second oil outlet valve 520 are opened. The oil pump 600 is then started to discharge oil.
[0052] In this embodiment, a temperature sensor 260 is also installed on the main oil pipe 210 and the metering tank 200. The temperature sensor 260 can detect the oil delivery temperature from the oil depot, and the actual oil output can be corrected based on the effect of temperature on the oil volume, so as to make the detection of the actual oil output more accurate.
[0053] Example 2
[0054] like Figure 5As shown, this application also proposes a metering and testing vehicle, including a vehicle body and an oil flow metering device with oil and gas recovery function as described above. The oil and gas recovery metering device is fixedly installed in the compartment of the vehicle body.
[0055] In summary, the oil flow metering device and metering testing vehicle with oil and gas recovery function proposed in this application, by installing an oil and gas recovery pipe at the top of the metering tank and connecting it to the oil and gas recovery pipe of the oil depot, allows the oil and gas entering the metering tank to enter the oil and gas recovery pipe of the oil depot for recovery during oil meter testing. This prevents the oil and gas from entering the air and causing environmental impact. Furthermore, by installing an anti-static connector, static electricity on the metering tank is eliminated, ensuring the safety of the testing area.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
