Existing metrological calibration devices consist of standard measuring containers and flatbed carts. Meterological calibration of a fuel dispenser requires multiple repetitive calibrations. However, existing standard measuring containers are independent tank or barrel structures. After each metrological calibration, the standard measuring container needs to be moved to the oil unloading area using a flatbed cart to empty it for re-calibration, which significantly delays the operation. After moving the measuring container, its level also needs to be adjusted again before metrological calibration, which also delays the operation. Utility Model Content

The flatbed trolley 1 can be pushed to move by holding the handle 1.3 by hand.

[0025] like Figures 1 to 3As shown, the support platform 2 is fixed on the flatbed cart 1. Specifically, a plurality of support rods 3 are provided between the support platform 2 and the bottom plate 1.1. The bottom ends of the support rods 3 are welded to the bottom plate 1.1, and the top ends thereof are welded to the support platform 2.

[0026] The bottom plate 1.1 and the supporting platform 2 are both made of stainless steel plates, and the push handle 1.3 and the supporting rod 3 are both made of stainless steel square tubes.

[0027] like Figures 1 to 3 As shown, there are four measuring containers 4, each of which is a quarter-cylinder-shaped structure. The four measuring containers 4 are all arranged on the support platform 2 and enclosed to form a cylindrical shape. The bottom end of each measuring container 4 is welded with a flange, and the flange is detachably connected to the support platform 2 by multiple bolts, so that the four measuring containers 4 are all installed on the support platform 2;

[0028] During measurement verification, the support platform 2 can support the measuring container 4, which can facilitate the disassembly and assembly of the measuring container 4. A damaged measuring container 4 can be replaced, and other measuring containers 4 can be reused. It is also convenient to disassemble the measuring container 4 for cleaning and maintenance.

[0029] The four measuring containers 4 are mounted on the supporting platform 2 to form a cylindrical shape, which is stable and can facilitate the orderly measurement and verification using the four measuring containers 4.

[0030] In addition, the measuring container 4 may also be a square box structure;

[0031] The measuring container 4 is made of stainless steel.

[0032] like Figures 1 to 3 As shown, a funnel 9 communicating with the interior of each metering container 4 is provided on the top. The fuel gun of the fuel dispenser is inserted into the funnel 9, and fuel can be easily added to the metering container 4 through the funnel 9. The funnel 9 is made of stainless steel.

[0033] like Figures 1 to 3 As shown, a transparent metering tube 8 is provided on the top of each metering container 4. The bottom end of the transparent metering tube 8 is connected to the interior of the metering container 4, and the top end thereof is connected to the interior of the funnel 9. The outer surface of the transparent metering tube 8 is provided with scale lines. During metering verification, the scale value at the scale line corresponding to the liquid level in the transparent metering tube 8 is read to measure the oil volume.

[0034] The transparent measuring tube 8 is made of a transparent glass tube.

[0035] like Figures 1 to 3 As shown, each metering container 4 is provided with a discharge pipe 6 for emptying, and each discharge pipe 6 is provided with a valve 7 .

[0036] like Figures 1 to 3As shown, there are four leveling mechanisms 5, which are all installed on the flatbed cart 1 and are respectively located at the four end corners of the bottom plate 1.1;

[0037] Specifically, each leveling mechanism 5 is composed of a screw 5.1, a support plate 5.2 and a handwheel 5.3; the screw 5.1 passes through the base plate 1.1 and is threadedly connected to the base plate 1.1, the support plate 5.2 is fixed to the bottom end of the screw 5.1, and the handwheel 5.3 is fixed to the top end of the screw 5.1. The screw 5.1 can be easily controlled by turning the handwheel 5.3 by hand;

When moving the flatbed cart 1, the screw 5.1 is rotated to make the support plate 5.2 suspended in the air. During measurement and calibration, after the flatbed cart 1 is stopped, the screw 5.1 can be rotated to make the support plate 5.2 contact the ground, and by adjusting each screw 5.1 and referring to each spirit level, the support platform 2 can be leveled. After the support platform 2 is leveled, the various measuring containers 4 installed thereon are also leveled accordingly.

[0039] The working principle and technical effects of this utility model are:

[0040] The measurement and verification device can be used to perform multiple repeated measurement and verification on the same fuel dispenser. According to the requirement that a fuel dispenser needs to perform multiple repeated measurement and verification, the measurement and verification device has four measuring containers 4, which can perform four repeated measurement and verification.

[0041] Push the flatbed cart 1 to move the metering container 4 to the fuel dispenser. After locking the running wheels 1.2, use the four leveling mechanisms 5 to level the support platform 2 and the four metering containers 4 mounted thereon. The leveling principle is to adjust the leveling mechanism 5 corresponding to the lower side, and lift the base plate 1.1 and the support platform 2 until each level is in a level state.

[0042] When performing metering verification on a fuel dispenser, insert the fuel gun into the funnel 9 and fill the metering container 4 with fuel. The amount of fuel is measured by reading the scale value at the scale line corresponding to the liquid level in the transparent metering tube 8. Fuel can be added to four metering containers 4 respectively, and the metering verification can be repeated four times on the same fuel dispenser.

[0043] After the metrological verification is completed, the metering container 4 is pushed to the oil unloading site by the flatbed cart 1, and the fuel in the four metering containers 4 can be uniformly emptied so that it can be used for the next metrological verification. Before the metrological verification, the four metering containers 4 are uniformly leveled, which can save operation time and improve the efficiency of metrological verification.
