[0002] Metrological verification plays a very important role in metrological work. It is an important measure to unify the value and ensure the accuracy and consistency of measuring instruments. It is an important form of value transfer or value traceability. It is an important condition for providing metrological guarantee for national economic construction. It is a means of national supervision of national measurement. The oil volume of gas stations needs to be verified regularly, and the metrological verification device can weigh and verify the oil volume.

[0003] A gas station calibration and metering device with publication number CN216978072U is disclosed. The patent sets an oil inlet mechanism and a trigger mechanism. With the cooperation of the oil inlet mechanism and the trigger mechanism, after the staff completes the oil filling, the interior of the oil tank can be in a sealed state to prevent air from the external environment from entering the oil tank and contacting the oil, and to prevent the oil from contacting and merging with the air in the external environment.

[0004] Although this patent can prevent the oil from coming into contact with and fusing with the air in the external environment, the unit volume of the fuel will change with the temperature. Especially in hot weather, the external surface temperature gradually rises and the volume of the fuel will expand accordingly. This means that the volume occupied by the same mass of fuel at high temperature will increase, resulting in a higher measurement result, which in turn affects the accuracy of the metering calibration results of the fuel dispenser.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application. Example

[0032] Reference Figure 1-Figure 5 , a fuel dispenser calibration and metering device, comprising a fuel tank 1, wherein a cooling component is provided inside the fuel tank 1;

[0033] The cooling component includes a spiral pipe 9. A placement cavity 8 is opened on the inner wall of the oil tank 1. The spiral pipe 9 is located inside the placement cavity 8. Both ends of the spiral pipe 9 extend through the outside of the oil tank 1 and are connected with both ends of a water pump 11. A condenser 10 is provided at one end of the spiral pipe 9. Both ends of the condenser 10 are connected with connecting ports 12. The spiral pipe 9 is connected to the condenser 10 through the two connecting ports 12.

[0034] By setting up the cooling component, the fuel inside the fuel tank 1 can be cooled. In the hot summer outdoors, the volume expansion and density reduction of the fuel may cause the metering result of the fuel dispenser metering device to be too high. At this time, the cooling component lowers the temperature of the fuel inside the fuel tank 1, which can reduce or eliminate the metering error caused by temperature changes, thereby improving the accuracy of the metering.

[0035] When cooling is required, the external coolant is pumped into the spiral pipe 9 through the water pump 11. A pipe (not shown) is provided at one end of the spiral pipe 9, and a valve is provided inside the pipe. The external coolant is pumped into the spiral pipe 9 from the pipe. After the pumping is completed, the valve inside the pipe is closed. Then, the coolant inside the spiral pipe 9 can effectively exchange heat with the fuel inside the fuel tank 1 to reduce the temperature of the fuel and avoid the high temperature outside from affecting the metering result of the fuel. The coolant inside the spiral pipe 9 can flow back to the inside of the condenser 10 through the water pump 11 to cool it down, and then be transported to the inside of the spiral pipe 9 to realize the recycling of the coolant.

[0036] Reference Figure 1-Figure 2 An oil inlet pipe 3 is connected to the top of the oil tank 1, an oil inlet port 4 is connected to the top of the oil inlet pipe 3, an oil outlet pipe 7 is connected to the bottom of the oil tank 1, a connecting seat 2 is fixedly connected to the bottom of the oil tank 1, a leveling component is provided inside the connecting seat 2, and the leveling component includes threaded rods 5. The number of threaded rods 5 is set to be multiple and located around the connecting seat 2. The threaded rods 5 are all threadedly connected to the connecting seat 2, the bottom of the threaded rods 5 is connected to a supporting foot 6, and a moving component is provided at the bottom of the oil tank 1.

[0037] The leveling assembly can adjust and correct the horizontal position of the fuel tank 1 as needed to ensure the flow and metering accuracy of the fuel during refueling.

[0038] When the calibration device is on an uneven ground, the threaded rod 5 can be rotated to fine-tune the height of the bottom of the oil tank 1 to keep it level with the ground. Then, an external level can be used to measure the level of the bottom of the oil tank 1 to ensure the horizontal state and increase the stability of the device.

[0039] Reference Figure 4-Figure 5 The moving component includes a driving component, a limiting component and a moving component. The driving component includes a worm 14. Two support plates 13 are fixedly connected to the bottom of the oil tank 1. The worm 14 is located between the two support plates 13 and is rotatably connected to the two support plates 13. Two groups of fixed plates 17 are fixedly connected to the bottom of the oil tank 1. The number of each group of fixed plates 17 is set to two. The limiting component includes a connecting block 18. One side of each fixed plate 17 is fixedly connected to the corresponding connecting block 18. A limiting groove is provided inside each connecting block 18. Two limiting blocks 19 are fixedly connected inside each limiting groove. The cross section of each limiting block 19 is semicircular. The moving component includes a connecting rod 16. The number of the connecting rods 16 is set to two. Each connecting rod 16 is rotatably connected to a corresponding group of fixed plates 17. A worm wheel 15 is fixedly connected to the outer wall of each connecting rod 16. The two worm wheels 15 are meshed with the worm 14. Both ends of each connecting rod 16 are fixedly connected to a transmission rod 20. The interior of each transmission rod 20 is rotatably connected to a moving wheel 21.

[0040] By setting the moving component, the calibration device can be conveniently moved when not being calibrated, specifically, the worm 14 is rotated. The worm 14 is a double-threaded worm 14, that is, the threads on both sides of the worm 14 are in opposite directions. When the worm 14 rotates, the worm wheels 15 on both sides can be rotated, so that the connecting rods 16 are both retracted toward the center direction of the oil tank 1. At this time, the internal shaft of the moving wheel 21 will be located in the limiting groove of the connecting block 18, and the shaft is limited by the limiting block 19. The limiting block 19 is made of elastic material and does not affect the normal rotation of the shaft. When the moving wheel 21 is not in use, it will always be in a folded state, and the limiting block 19 further plays a limiting role.

[0041] When movement is required, the worm 14 is rotated to drive the worm wheel 15 to rotate, so that the moving wheels 21 on both sides rotate toward the outside of the oil tank 1. At this time, the moving wheels 21 will contact the ground, driving the oil tank 1 to move, so that the calibration device can be moved and adjusted in different places or working conditions. Example

[0042] Reference Figure 1-Figure 3 The condenser 10 is connected to the oil tank 1 by bolts.

[0043] The condenser 10 is a detachable structure. In winter, the volume contraction and density increase of the fuel may cause the metering result of the fuel dispenser metering device to be low. At this time, the condenser 10 can be replaced with a heater, and the liquid inside the spiral pipe 9 can be replaced with water. The heater slightly heats the liquid inside the spiral pipe 9 to keep the fuel inside the fuel tank 1 warm. Firstly, it can slow down the temperature drop of the fuel and prevent its density from increasing, thereby reducing the metering error and ensuring that the metering result of the fuel dispenser is more accurate. Secondly, in the cold winter environment, the fuel tends to become viscous. The heater can increase the temperature of the fuel and improve its fluidity, making it easier to measure.

[0044] Working principle: When cooling is required, the external coolant is pumped into the spiral pipe 9 through the water pump 11. A pipe (not shown) is provided at one end of the spiral pipe 9, and a valve is provided inside the pipe. The external coolant is pumped into the spiral pipe 9 from the pipe. After the pumping is completed, the valve inside the pipe is closed. Then, the coolant inside the spiral pipe 9 can effectively exchange heat with the fuel inside the fuel tank 1 to reduce the temperature of the fuel and avoid the high temperature of the outside from affecting the metering result of the fuel. The coolant inside the spiral pipe 9 can flow back to the inside of the condenser 10 through the water pump 11 to cool it down, and then it is transported to the inside of the spiral pipe 9 to realize the recycling of the coolant.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
