Description

Technical Field

[0001] The utility model relates to the technical field of a calibration gauge structure for a fuel dispenser, in particular to a calibration gauge for a fuel dispenser which is easy to transport. Background Art

[0002] Fuel dispenser calibration is the process of comprehensively inspecting and testing the metering performance of fuel dispensers to ensure metering accuracy and prevent fraud. The main contents of fuel dispenser calibration include appearance and structure inspection, metering performance testing, and anti-fraud 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 fuel 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 fuel 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 one calibration operation is completed, the fuel in the measuring tank is discharged into the fuel 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 with too large a volume is more likely to be damaged than the measuring tank with smaller volume, and may even be unable to pass through the above-mentioned special terrain smoothly. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of the present utility model is to provide a fuel dispenser calibration tool that is easy to transport, which is used to solve the problem in the prior art that the overly large measuring tank is easily damaged when passing through special terrains such as bridge holes, tunnels and steep slopes, and even cannot pass smoothly in extremely special circumstances such as when the tunnel height is relatively low.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides a fuel dispenser calibration instrument that is easy to transport, including an oil storage tank, a measuring tank installed on the oil storage tank, a liquid level gauge provided on the measuring tank, the measuring tank and the oil storage tank are connected, a second valve is provided 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 provided between two of the interconnected measuring tanks; a weighing module is provided under the oil storage tank, and the weighing module weighs the fuel injected into the measuring tank under the action of a lifting module.

[0007] 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.

[0008] Optionally, there is only one second measuring tank.

[0009] 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 the bottom of the first measuring tank to the bottom of the second measuring tank from high to low.

[0010] Optionally, the bottom of the second measuring tank is connected to the oil storage tank via a second oil pipe, and the second valve is provided on the second oil pipe; the second oil pipe slopes from the bottom of the second measuring tank to the oil storage tank from high to low.

[0014] As described above, the utility model of a fuel dispenser calibration tool that is easy to transport has at least the following beneficial effects:

[0015] The gas station calibration gauge for fuel dispensers that is easy to transport has multiple measuring tanks that are interconnected, and 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 separately; when the transport vehicle passes through some special terrains, such as bridge holes, tunnels, and steep slopes, the measuring tank without increasing the volume can also pass smoothly without being damaged 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., 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 measuring tanks with excessively large volumes. This solves the problem in the prior art that measuring tanks with excessively large volumes are easily damaged when passing through special terrains such as bridge holes, tunnels, and steep slopes, and even cannot pass smoothly in extremely special circumstances such as when the tunnel height is relatively low.

DETAILED DESCRIPTION

[0022] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0023] 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 this utility model. Therefore, they have no substantive 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 this utility model without affecting the efficacy and purpose that can be achieved by this utility model. 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 this utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0024] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0025] See also Figure 1 The utility model provides a fuel dispenser calibration tool that is easy to transport, like the existing technology Figure 2 As shown in the figure, the calibration instrument 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 one calibration is completed, 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 gauge 5 installed on the measuring tank 2.

[0026] like Figure 3 As shown, the difference from the prior art is that the measuring instrument has multiple measuring tanks 2, and the multiple measuring tanks 2 are interconnected, and a first valve 25 is provided between the two interconnected measuring tanks 2; when calibrating some gas pumps with larger refueling values, the measuring instrument does not need to increase the volume of a measuring tank 2 like the existing calibration device to meet the calibration requirements, but calibrates the refueling value of the gas pump through multiple relatively small and interconnected measuring tanks 2. In this way, when the vehicle transporting the calibration instrument passes through some special terrains, such as bridge holes, tunnels and steep slopes, the measuring instrument 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.

[0027] like Figure 4As shown, a weighing module 9 is provided 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.

[0028] In another embodiment, see 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 and calibration value of the fuel dispenser; the designer can also design a third measuring tank 2, a fourth measuring tank 2, etc. with other volumes different from the first measuring tank 21 and the second measuring tank 22 on the oil storage tank 1; the second measuring tank 22 is only provided with one, 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.

[0029] In another embodiment, see Figure 3 The bottom of the first measuring tank 21 and the bottom of the second measuring tank 22 are connected by a first oil pipe 23, and the first valve 25 is provided on the first oil pipe 23; the first oil pipe 23 slopes from the bottom of the first measuring tank 21 to the bottom of the second measuring tank 22 from high to low; with this 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 for a dedicated liquid pump.

[0030] 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 provided 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. 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.

[0031] In another embodiment, see Figure 4The 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.

[0032] In another embodiment, see Figure 1 and Figure 4 , also includes a tank rack 12, the oil tank 1 is installed in the tank rack 12, and the first support leg 11 is set at the bottom of the tank rack 12. This design fully ensures the stability of the oil tank 1 during transportation and the smoothness of the placement process.

[0033] In another embodiment, see Figure 1 and Figure 4 , further comprising a control module 31 and a calculation module 32, both of which are mounted on the tank frame 12 to ensure the overall stability of the measuring tool. At the same time, the operator can directly operate the measuring tool through the control module 31. As for the specific working process of the control module 31, it has been fully disclosed in 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.

[0034] 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 values ​​measured by the temperature measurement module are transmitted to the calculation module 32, further improving the accuracy of the calibration results of the fuel dispenser by this measuring tool.

[0035] 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 position 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.

[0036] 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 separately; when the 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 conditions such as damage will occur. For some fuel dispensers with particularly large calibration values, the design of the weighing module 9 and the use of the mass method (i.e., the volume of the injected fuel is obtained by dividing the weighed value by the density of the fuel) can also complete the calibration, thereby eliminating the need to manufacture measuring tanks 2 with excessively large volumes; this solves the problem in the prior art that measuring tanks 2 with excessively large volumes are prone to damage when passing through special terrains such as bridge holes, tunnels and steep slopes, and even cannot pass smoothly in extremely special circumstances such as when the tunnel height is relatively low. Therefore, the present invention effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0037] 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 skilled in 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 one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
