Oiling machine verification measuring tool used in field

Abstract

The utility model provides an oiling machine verification measuring tool used in the field, and belongs to the technical field of oiling machine verification measuring tool structures. According to the calibration measuring tool, more than three spring dampers which are not on the same straight line are installed at the bottom of a supporting assembly, and each spring damper corresponds to a telescopic controller and a telescopic piece; due to the design that the infrared sensor is arranged between the elastic moving part of the spring damper and the fixed supporting leg and controls the stretching and retracting of the telescopic part through the telescopic controller, when the calibration measuring tool is conveyed to the field, even if the ground is uneven, the measuring tool cannot be horizontally placed temporarily, and the calibration measuring tool is convenient to use. However, the compressed distance of the elastic moving part of the spring damper is detected through the infrared sensor, and then the telescopic part is controlled by the telescopic controller to extend outwards or retract by different lengths, so that the measuring tool can be adjusted to a horizontal position, and the problem that the verification result is inaccurate when a field oiling machine is verified in the prior art is solved.

[0003] Gas station calibration is crucial for ensuring accurate metering, regulating market behavior, improving service quality, and extending equipment life. Existing calibration devices for gas station calibration typically use a level gauge mounted on a measuring cylinder to measure the volume of fuel injected into the cylinder. However, when calibrating gas station calibration equipment in the field, the calibration equipment needs to be transported to the field. Unlike urban terrain, which is often uneven, the field calibration gauge is inevitably jolted when placed. Furthermore, the level gauge on the measuring cylinder cannot accurately measure the volume, resulting in inaccurate calibration results. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of the present utility model is to provide a gas station calibration gauge for outdoor use, which is used to solve the problem in the prior art that when calibrating gas station in the field, the gas station calibration gauge is subjected to bumps during placement due to the undulating terrain and the measurement of the liquid level gauge on the measuring cylinder is difficult to ensure accuracy, resulting in inaccurate calibration results of the gas station calibration gauge.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figures 1 to 3 . 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.

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.

[0020] 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.

[0021] See also Figure 1 The utility model provides a fuel dispenser calibration instrument for outdoor use. Like the prior art, the calibration instrument also includes a fuel tank 1, on which a measuring tank 2 is installed. The measuring tank 2 is connected to the fuel tank 1, and a second valve 26 is provided between the measuring tank 2 and the fuel tank 1. After one calibration is completed, the fuel in the measuring tank 2 flows into the fuel 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.

[0022] like Figure 2 and Figure 3 As shown, the difference from the prior art is that more than three spring dampers 6 are installed at the bottom of the oil storage tank 1 and are not in a straight line, and each of the spring dampers 6 corresponds to a telescopic controller 7 and a telescopic member 8; an infrared sensor 63 is provided 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 gauge is transported to the field, even if the present gauge cannot be temporarily placed horizontally due to uneven ground, the infrared sensor 63 detects the distance to which the elastic movable portion 61 of the spring damper 6 is compressed, and then the telescopic member 8 is controlled to extend or retract to different lengths by the telescopic controller 7, so that the present gauge 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 gauge and the telescopic member 8 is difficult to adjust, a more accurate calibration value can also be obtained by calculating the average value of the readings of more than three liquid level gauges 5.

[0023] like Figure 3 As 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), and the calibration result of the liquid level meter 5 is further corrected to make the final calibration result more accurate.

[0024] The oil storage tank 1 is not necessary and can be replaced by other supports as long as it plays a supporting role for the measuring tank 2. We refer to the supports below the measuring tank 2 as support components.

[0025] In another embodiment, see Figure 3 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.

[0026] In another embodiment, see Figure 3, also includes a tank rack 12, the oil storage tank 1 is installed in the tank rack 12, the first support leg 11 is arranged at the bottom of the tank rack 12, there are more than three first support legs 11, and a spring damper 6 is installed on each first support leg 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 smoothness of the placement process.

[0027] In another embodiment, see Figure 3 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-slip 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-slip protrusions can be anti-slip grooves or nail-shaped protrusions.

[0028] In another embodiment, see Figure 1 and Figure 3 , 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.

[0029] 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.

[0030] In other embodiments, Figure 2 As shown, the second valve 26 is an electric valve or a manual valve. The second valve 26 connects the measuring tank 2 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.

[0031] In summary, the present invention is provided with three or more spring dampers 6 which are not in a straight line at the bottom of the support assembly, and each spring damper 6 corresponds to a telescopic controller 7 and a telescopic member 8; an infrared sensor 63 is provided between the elastic moving portion 61 of the spring damper 6 and the fixed support leg 62, and the infrared sensor 63 is designed to control the extension and retraction of the telescopic member 8 by the telescopic controller 7. When the calibration gauge is transported to the field, even if the gauge cannot be placed horizontally temporarily due to uneven ground, the infrared sensor 63 can detect the elasticity of the spring damper 6 and the telescopic member 8. The elastic movable portion 61 of the spring damper 6 is compressed to a certain distance, and then the telescopic member 8 is controlled to extend or retract to different lengths by the telescopic controller 7, so that the measuring tool can be adjusted to a horizontal position. Furthermore, by designing three or more parallel level gauges 5, when there is a small error in the horizontality of the measuring tool and the telescopic member 8 is difficult to adjust, a more accurate calibration value can be obtained by calculating the average value of the readings of the three or more level gauges 5. The weighing module 9 further corrects the calibration result through the mass method calibration, making the final calibration result more accurate. Therefore, the present utility model effectively overcomes the shortcomings of the existing technology and has high industrial utilization value.

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.
