Description

Technical Field

[0001] The invention belongs to the technical field of fuel dispenser calibration equipment structure, and in particular relates to a fuel dispenser calibration equipment. Background Art

[0002] Fuel dispenser calibration refers to the process of comprehensively inspecting and testing the metering performance of fuel dispensers to ensure their metering accuracy and prevent cheating. The main contents of fuel dispenser calibration include appearance and structure inspection, metering performance test and anti-cheating inspection.

[0003] Gas station calibration is of great significance for ensuring accurate measurement, regulating market behavior, improving service quality and extending equipment life. Figure 2 As shown, a measuring tank is installed on the oil storage tank, and a liquid level gauge is set on the measuring tank to measure and read the volume of fuel injected into the measuring tank; the volume of the measuring tank is determined according to the calibration standard. If the calibration standard values ​​differ greatly, two or more measuring tanks are generally installed on the oil storage tank. The large-volume measuring tank is used to calibrate the large value, and the small-volume measuring tank is used to calibrate the small value; after a calibration operation is completed, the fuel in the measuring tank is discharged into the oil storage tank.

[0004] For some gas pumps with larger calibration values, the volume of the measuring tank also increases accordingly. When calibrating some gas pumps in the field, the calibration device needs to be transported to the field. If the volume of the measuring tank is too large, when the transport vehicle passes through some special terrains, such as bridge holes, tunnels and steep slopes, the measuring tank that is too large is more likely to be damaged than the measuring tank with smaller volume, and may even fail to pass through the above-mentioned special terrain smoothly.

[0005] At the same time, the calibration equipment is transported to the field. Because the terrain in the field is not as flat as the ground in the city, it is often undulating. When the calibration gauge of the gas pump is placed, it is inevitably bumpy due to the undulating terrain. At the same time, the measurement of the liquid level gauge on the measuring cylinder is difficult to ensure accuracy, resulting in inaccurate calibration results. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a fuel dispenser calibration device to solve the problem in the prior art that when transporting practical fuel dispenser calibration devices in the field, the measuring cylinder with a large volume is easily damaged when passing through special terrains such as bridge holes, tunnels and steep slopes, and even cannot pass smoothly under extremely special circumstances such as when the tunnel height is relatively low; and because of the undulating terrain in the field, the fuel dispenser calibration equipment is subject to bumps during placement in the field, and the measurement of the liquid level gauge on the measuring cylinder is difficult to ensure accuracy, thereby resulting in inaccurate calibration results of the fuel dispenser.

[0007] To achieve the above-mentioned purpose and other related purposes, the present invention provides a fuel dispenser calibration device, including an oil storage tank, a measuring tank is installed on the oil storage tank, the measuring tank is connected to the oil storage tank, a second valve is arranged between the measuring tank and the oil storage tank, there are multiple measuring tanks, the multiple measuring tanks are connected to each other, and a first valve is arranged between two measuring tanks that are connected to each other; more than three liquid level gauges arranged in parallel are installed on each of the measuring tanks; more than three spring dampers that are not in a straight line are installed at the bottom of the oil storage tank, and each of the spring dampers corresponds to a telescopic controller and a telescopic member; an infrared sensor is arranged between the elastic moving part and the fixed support leg of the spring damper, and the infrared sensor controls the extension and retraction of the telescopic member through the telescopic controller; a weighing module is arranged under the oil storage tank, and the weighing module weighs the fuel injected into the measuring tank under the action of the lifting module.

[0008] Optionally, the multiple measuring tanks include a first measuring tank and a second measuring tank, the first measuring tank and the second measuring tank are connected, and the second measuring tank and the oil storage tank are connected; the first valve is arranged between the first measuring tank and the second measuring tank, and the second valve is arranged between the second measuring tank and the oil storage tank.

[0009] Optionally, there is only one second measuring tank.

[0010] Optionally, the bottom of the first measuring tank and the bottom of the second measuring tank are connected through a first oil pipe, and the first valve is set on the first oil pipe; the first oil pipe is inclined from high to low from the bottom of the first measuring tank to the bottom of the second measuring tank; the bottom of the second measuring tank and the oil storage tank are connected through a second oil pipe, and the second valve is set on the second oil pipe; the second oil pipe is inclined from high to low from the bottom of the second measuring tank to the oil storage tank.

[0011] Optionally, a first support leg is provided at the bottom of the oil tank, and the oil tank is suspended above the ground by the first support leg; the weighing module includes a weighing plate, a second support leg is provided at the bottom of the weighing plate, and the weighing plate is suspended above the ground by the second support leg; the weighing plate is located between the ground and the bottom surface of the oil tank; the lifting module is a hydraulic lift, and the front fork of the hydraulic lift is located between the weighing plate and the ground.

[0012] Optionally, it also includes a fuel tank rack, the fuel storage tank is installed in the fuel tank rack, the first support leg is arranged at the bottom of the fuel tank rack, there are more than three first support legs, and a spring damper is installed on each of the first support legs; the fixed end of the telescopic member is fixedly installed on the fuel tank rack, and the telescopic end of the telescopic member faces the ground; the telescopic controller is installed on the fuel tank rack.

[0013] Optionally, a lifting plate is fixedly mounted on the telescopic end of the telescopic member, and an anti-slip protrusion is provided on the bottom surface of the lifting plate.

[0017] As described above, the fuel dispenser calibration device of the present invention has at least the following beneficial effects:

[0018] The fuel dispenser calibration equipment has multiple measuring tanks, which are interconnected. A first valve is provided between two interconnected measuring tanks. For some fuel dispensers with larger calibration values, there is no need to increase the volume of a measuring tank alone. When transport vehicles pass through some special terrains, such as bridge holes, tunnels, and steep slopes, the measuring tanks without increased volume can also pass smoothly without damage or other adverse situations. For some fuel dispensers with particularly large calibration values, the calibration can be completed by designing a weighing module and using the mass method (i.e., dividing the weighed value by the density of the fuel to obtain the volume of the injected fuel), so there is no need to manufacture measuring tanks with excessively large volumes. In addition, when the calibration equipment is transported to the field, even if the equipment cannot be placed horizontally temporarily due to the uneven ground, the infrared sensor can detect the compression distance of the elastic moving part of the spring damper, and then the telescopic controller can be used to control the telescopic part to extend or retract different lengths, so that the equipment can be adjusted to a horizontal position; when there are more than three parallel level gauges and there is a small error in the horizontality of the equipment and the telescopic part is difficult to adjust, a more accurate calibration value can be obtained by averaging the readings of more than three level gauges; and the weighing module is calibrated by the mass method to further correct the calibration result, so that the final calibration result is more accurate.

DETAILED DESCRIPTION

[0025] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0026] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0027] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0028] See also Figure 1 The present invention provides a fuel dispenser calibration device, like the prior art Figure 2 As shown in , the calibration equipment also includes an oil storage tank 1, on which a measuring tank 2 is installed, the measuring tank 2 is connected to the oil storage tank 1, and a second valve 26 is provided between the measuring tank 2 and the oil storage tank 1. After completing a calibration, the fuel in the measuring tank 2 flows into the oil storage tank 1 through the second valve 26. During the next calibration, the second valve 26 is closed, and the calibration value is read by the liquid level meter 5 installed on the measuring tank 2.

[0029] like Figure 3As shown, the difference from the prior art lies in that the present device has multiple measuring tanks 2, which are interconnected, and a first valve 25 is provided between two interconnected measuring tanks 2; when calibrating some gas pumps with larger refueling values, the present device does not need to increase the volume of a measuring tank 2 like the existing calibration devices to meet the calibration requirements, but calibrates the refueling values ​​of the gas pumps through multiple relatively small and interconnected measuring tanks 2. In this way, when the vehicle transporting the present calibration device passes through some special terrains, such as bridge holes, tunnels and steep slopes, the equipment equipped with a relatively small measuring tank 2 can pass smoothly, and compared with the larger measuring tank 2, the probability of adverse conditions such as damage is effectively reduced.

[0030] like Figure 4 As shown, more than three spring dampers 6 that are not in a straight line are installed at the bottom of the oil storage tank 1, and each of the spring dampers 6 corresponds to a telescopic controller 7 and a telescopic member 8; an infrared sensor 63 is arranged between the elastic movable portion 61 of the spring damper 6 and the fixed support leg 62, and the infrared sensor 63 controls the extension and retraction of the telescopic member 8 through the telescopic controller 7; when the present calibration equipment is transported to the field, even if the present equipment cannot be placed horizontally temporarily due to the uneven ground, the infrared sensor 63 can detect the distance by which the elastic movable portion 61 of the spring damper 6 is compressed, and then the telescopic controller 7 can be used to control the extension or retraction of the telescopic member 8 to different lengths, so that the present equipment can be adjusted to a horizontal position; combined with the design that more than three liquid level gauges 5 arranged in parallel are installed on each measuring tank 2, when there is a small error in the horizontality of the present equipment and the telescopic member 8 is difficult to adjust, a relatively accurate calibration value can be obtained by calculating the average value of the readings of more than three liquid level gauges 5.

[0031] like Figure 1 and Figure 4 As shown, a weighing module 9 is arranged below the oil storage tank 1. The weighing module 9 weighs the fuel injected into the measuring tank 2 under the action of the lifting module 4. For some fuel dispensers with particularly large calibration values, the weighing module 9 is designed to complete the calibration using the mass method (i.e., the volume of the injected fuel is obtained by dividing the weighed value by the density of the fuel), thereby eliminating the need to manufacture a measuring tank 2 with an excessively large volume. At the same time, the weighing module 9 further corrects the calibration result of the liquid level meter 5 through the calibration using the mass method, thereby making the final calibration result more accurate.

[0032] In another embodiment, see Figure 1 and Figure 3, multiple measuring tanks 2 include a first measuring tank 21 and a second measuring tank 22, the first measuring tank 21 and the second measuring tank 22 are connected, and the second measuring tank 22 is connected to the oil storage tank 1; the first valve 25 is arranged between the first measuring tank 21 and the second measuring tank 22, and the second valve 26 is arranged between the second measuring tank 22 and the oil storage tank 1. The first measuring tank 21 can be set as one or more, and the number of the first measuring tank 21 is determined by the specific model of the fuel dispenser and the calibration value; the designer can also design to set other third measuring tanks 2, fourth measuring tanks 2, etc. on the oil storage tank 1 whose volumes are different from the first measuring tank 21 and the second measuring tank 22; the second measuring tank 22 is only one, and compared with setting multiple second measuring tanks 22, the advantage of designing only one second measuring tank 22 that is finally connected to the oil storage tank 1 is that it is convenient for the operator to adjust the calibration value.

[0033] In another embodiment, see Figure 1 and Figure 3 The bottom of the first measuring tank 21 and the bottom of the second measuring tank 22 are connected through the first oil pipe 23, and the first valve 25 is arranged on the first oil pipe 23; the first oil pipe 23 is inclined from the bottom of the first measuring tank 21 to the bottom of the second measuring tank 22 from high to low; with such a design, when the first valve 25 is opened, the fuel in the first measuring tank 21 can automatically flow into the second measuring tank 22 under the action of gravity, without the need to specially configure a liquid pump.

[0034] like Figure 3 As shown, similarly, the bottom of the second measuring tank 22 is connected to the oil storage tank 1 through a second oil pipe 24, and the second valve 26 is arranged on the second oil pipe 24; the second oil pipe 24 is inclined from the bottom of the second measuring tank 22 to the oil storage tank 1 from high to low, and when the second valve 26 is opened, the fuel in the second measuring tank 22 can automatically flow into the oil storage tank 1 under the action of gravity, and there is no need to specially configure a liquid pump.

[0035] In another embodiment, see Figure 4 The bottom of the oil storage tank 1 is provided with a first support leg 11, and the oil storage tank 1 is suspended from the ground by the first support leg 11; the weighing module 9 includes a weighing plate 91, and the bottom of the weighing plate 91 is provided with a second support leg 92, and the weighing plate 91 is suspended from the ground by the second support leg 92; the weighing plate 91 is located between the ground and the bottom surface of the oil storage tank 1; the lifting module 4 is a hydraulic lift, and the front fork 41 of the hydraulic lift is located between the weighing plate 91 and the ground; only when necessary, the operator operates the hydraulic lift to lift the weighing plate 91 to weigh the weight of the fuel injected into the measuring tank 2, and when there is no need to use the mass method for calibration, the operator operates the hydraulic lift to lower the weighing plate 91.

[0036] In another embodiment, see Figure 4 , also includes a tank rack 12, the oil storage tank 1 is installed in the tank rack 12, the first support leg 11 is set at the bottom of the oil tank rack 12, the first support leg 11 is more than three, and a spring damper 6 is installed on each of the first support legs 11; the fixed end of the telescopic member 8 is fixedly installed on the tank rack 12, and the telescopic end of the telescopic member 8 faces the ground; the telescopic controller 7 is installed on the tank rack 12. This design fully ensures the stability of the oil storage tank 1 during transportation and the stability of the placement process.

[0037] In another embodiment, see Figure 4 The telescopic end of the telescopic member 8 is fixedly mounted with a lifting plate 81, and the bottom surface of the lifting plate 81 is provided with anti-skid protrusions to avoid the problem of slipping on the ground when the telescopic end of the telescopic member 8 extends downward. The telescopic member 8 can use a hydraulic telescopic cylinder, and the anti-skid protrusions can be anti-skid patterns or nail-shaped protrusions.

[0038] In another embodiment, see Figure 1 and Figure 4 , and also includes a control module 31 and a calculation module 32. The control module 31 and the calculation module 32 are both installed on the tank frame 12 to ensure the overall stability of the equipment. At the same time, the operator can directly operate the equipment through the control module 31. As for the specific working process of the control module 31, it has been fully disclosed by the prior art and will not be repeated here. The design of the calculation module 32 can calculate the reading of the liquid level meter 5 and the value of the weighing module 9 to obtain a more accurate calibration result.

[0039] In another embodiment, a temperature measurement module is provided on the measuring tank 2. The density of the fuel is slightly different at different temperatures. The value measured by the temperature measurement module is transmitted to the calculation module 32, further improving the accuracy of the fuel dispenser calibration results of the device.

[0040] In other embodiments, Figure 3 As shown, the first valve 25 is an electric valve. Since the first valve 25 connects the first measuring tank 21 and the second measuring tank 22, it is often located in a relatively central position on the upper part of the oil storage tank 1. If it is designed as a manual valve, it is often difficult to operate. The second valve 26 connects the second measuring tank 22 and the oil storage tank 1 and can be arranged at the edge of the upper part of the oil storage tank 1. Therefore, the second valve 26 can be designed as an electric valve or a manual valve.

[0041] In summary, the present invention has a design in which there are multiple measuring tanks 2, the multiple measuring tanks 2 are interconnected, and a first valve 25 is provided between two interconnected measuring tanks 2. For some fuel dispensers with larger calibration values, there is no need to increase the volume of a measuring tank 2 alone; when a transport vehicle passes through some special terrains, such as bridge holes, tunnels, and steep slopes, the measuring tank 2 without increasing the volume can also pass smoothly, and no adverse situations such as damage will occur. For some fuel dispensers with particularly large calibration values, the calibration can be completed by designing a weighing module 9 and using the mass method (i.e., dividing the weighed value by the density of the fuel to obtain the volume of the injected fuel), so there is no need to manufacture a measuring tank 2 with an excessively large volume. In addition, when the calibration equipment is transported to the field, even if the equipment cannot be placed horizontally temporarily due to the uneven ground, the infrared sensor 63 detects the distance that the elastic moving part 61 of the spring damper 6 is compressed, and then the telescopic controller 7 controls the telescopic part 8 to extend or retract different lengths, so that the equipment can be adjusted to a horizontal position; when there are more than three parallel level gauges 5, there is a small error in the horizontality of the equipment, and the telescopic part 8 is difficult to adjust, by calculating the average value of the readings of more than three level gauges 5, a more accurate calibration value can be obtained; and the weighing module 9 further corrects the calibration result through the calibration of the mass method, so that the final calibration result is more accurate. Therefore, the present invention effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
