Description

Technical Field

[0001] The invention relates to the technical field of oil discharging calibration of a fuel dispenser, in particular to a portable fuel dispenser metering and calibration device. Background Art

[0002] Fuel dispensers have developed along with the development of automobiles and road traffic. They are sales terminals in the retail industry for refined oil products and metering equipment used for sales settlement, making refueling convenient, fast and accurate. In addition to oil transportation and metering, they also have functions such as network management, convenient payment and value-added services.

[0003] The purpose of fuel dispenser metering and calibration is to ensure the metering accuracy of fuel dispensers, safeguard the legitimate rights and interests of consumers, and ensure fairness and justice in the fueling market. To achieve fuel metering and calibration, designated equipment must be used. The basic method is: select the fuel dispenser to be tested, connect the fuel gun to the oil inlet of the equipment, and inject a proper amount of fuel into it. The fuel elevation value is obtained through the internal metering component, and then compared with the standard value, it can be quickly determined whether the fuel dispenser's metering is accurate.

[0004] However, the existing fuel dispenser measurement and verification equipment has the following shortcomings:

[0005] Commonly used fuel types are mainly gasoline and diesel. Since the density of fuel is lower than that of water, it will expand and contract due to the influence of external temperature. Traditional equipment is limited by its own structure, and the construction and value conditions of the oil conduction environment are relatively simple. It is impossible to obtain multiple fuel elevation values ​​by adjusting the fuel injection environment, resulting in low accuracy of equipment calibration results.

[0006] Therefore, we proposed a portable fuel dispenser metering and calibration equipment to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a portable fuel dispenser metering and calibration equipment. Through the oil filling adjustment mechanism and the oil body sampling mechanism, multiple oil storage tanks are arranged for multiple sampling of fuel. According to the number of oil storage tanks and the limitation of standard values, two incremental values ​​are preset, and the temperature adjustment in the first extended empty pipe is completed one by one through the hot and cold components. During the process, equal amounts of fuel are collected in sequence. Due to the different fuel injection temperatures, the expansion coefficients of the fuel samples in each oil storage tank are also different. Finally, the equal amounts of fuel samples have different elevation values. The higher the fuel injection temperature, the greater the elevation value obtained. The relevant components in the electrical control box can accurately calculate the actual growth value of each portion of fuel at different temperatures. Multiple data can still be consistent with the standard fuel elevation value after deducting the growth amount, which means that the oil output of the fuel dispenser to be tested is not affected by the external temperature, so as to solve the problems raised by the above-mentioned background technology.

[0042] according to Figure 4 , Figure 8 and Fig. 9As shown, a locking nut 507 is provided inside the triangular seat 508, and the solid rod 506 and the triangular seat 508 are fixedly connected by the locking nut 507.

[0043] according to Figure 1 and Fig.10 As shown, the intermittent oil filling mechanism 6 includes an expansion outer ring 601, the bottom of the expansion outer ring 601 is fixedly installed on the top of the first extended empty tube 3, the top of the expansion outer ring 601 is fixedly installed with a second extended empty tube 602, and the outer wall of the second extended empty tube 602 is fixedly installed with two first flanges 603, and the interior of each first flange 603 is fixedly inserted with a second electric push rod 604, and the axial ends of the two second electric push rods 604 are fixedly sleeved with an arc-shaped pressing plate 605, and the two arc-shaped pressing plates 605 are both placed inside the second extended empty tube 602. By presetting the above-mentioned components and utilizing the mutual coordination of these components, the two arc-shaped pressing plates 605 are slowly driven to move relative to each other, thereby reducing the space inside the second extended empty tube 602 and fixing the gun barrel so that it is centered in the first extended empty tube 3 to prevent the oil gun from tilting.

[0044] according to Figure 3 and Fig.10 As shown, the outer wall of the second extended hollow tube 602 is fixedly installed with a third external base 606, the outer wall of the third external base 606 is fixedly installed with a load-bearing support plate 607, the bottom of the load-bearing support plate 607 is fixedly installed with two second flanges 608, the inner wall of each second flange 608 is fixedly inserted with a pneumatic push rod 609, and the shaft ends of the two pneumatic push rods 609 are fixedly sleeved with a lifting frame 610. By presetting the above-mentioned components and utilizing the coordination of these components, the lifting frame 610 and its connected parts can be quickly driven up and down, prompting the rubber pad 616 to push the trigger to complete the oil release.

[0045] according to Figure 3 and Fig.10As shown, two first grafting plates 611 are welded to the outer wall of the lifting frame 610, and the tops of the two first grafting plates 611 are fixedly installed with assembly blocks 612, and an inner connecting rod 614 is placed between the inner walls of the two assembly blocks 612. A metal card cover 613 is fixedly connected to the top of each assembly block 612, and the inner walls of the two metal card covers 613 are wrapped around the outer walls of the inner connecting rod 614, and a second external connecting plate 615 is fixedly installed on the outer wall of the inner connecting rod 614, and a rubber pad 616 is fixedly installed on the top of the second external connecting plate 615. By presetting the above components, the metal card cover 613 can be flexibly disassembled and assembled, ensuring that the gun handle can cross between the lifting frame 610 and the metal card cover 613, providing the necessary conditions for intermittent oil release of the equipment.

[0046] according to Fig.10 As shown, a second grafting plate 617 is welded to the outer wall of the load-bearing support plate 607, and a starter and stopper 618 and a timer 619 are fixedly installed on the bottom of the second grafting plate 617 respectively.

[0047] according to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the first external base 401 is fixedly mounted on the outer wall of the first extended empty tube 3, and the first external base 401 is fixedly mounted on the inner wall of the metal outer tube 1. A reinforcing outer ring 7 is fixedly mounted on the outer wall of the metal outer tube 1, and a group of built-in plates 8 are fixedly mounted inside the reinforced outer ring 7, and a lifting threaded support foot 9 is fixedly mounted on the outer wall of each built-in plate 8.

[0048] The effect achieved by the entire mechanism is as follows: in the preparation stage, the equipment is first moved to the designated area, each lifting threaded support foot 9 is adjusted synchronously, the height of the bottom support plate 501 from the ground is reasonably set to ensure that the recycling container can be placed therein, and then the external line is connected to the power supply of the equipment to provide energy for the multiple electrical components therein, and a first set of electric push rods 422 is turned on, and the movable connectivity between the oil pipeline 419 and the telescopic pipeline 420 is used to drive the telescopic pipeline 420 to be inserted into the interior of a corresponding oil storage tank 510.

[0049] During the gun body fixing stage, the gun barrel is inserted from the second extended hollow tube 602, and is sequentially inserted horizontally into the first limiting sleeve 414 and the second limiting sleeve 418, so that the gun barrel body is completely placed inside the first extended hollow tube 3, and the two second electric push rods 604 are simultaneously turned on to drive the two connected arc-shaped pressing plates 605 to move relative to each other until the end of the gun barrel is fixed. By utilizing the shape of the oil gun, the gun handle can be accurately placed inside the lifting frame 610, and the inner connecting rod 614 is manually installed and placed between the two assembly blocks 612 to ensure that the inner connecting rod 614 and its connected parts can span the inside of the gun handle. The metal card cover 613 is used to complete the fixing, and the touch screen 620 is operated. The time for each oil discharge is set according to the oil output per minute of the oil gun and the capacity of the oil storage tank 510, the number of oil discharges is set according to the number of oil storage tanks 510, and the interval time for each oil discharge is set according to the metering rate of the mechanism.

[0050] During the equipment manufacturing stage, since the fuel oil will not shrink significantly within the range of 20°C, the electrical control box 402 sets three adjustment temperatures based on the standard value, and the values ​​are all 5°C apart. The temperature in the first extended empty pipe 3 is monitored in real time by the temperature sensor 415. After the electrical control box 402 obtains the initial value, it selects the heating or cooling component according to the initial temperature, and first controls the temperature in the first extended empty pipe 3 to within the standard range. The output power of the relevant components is based on the actual data obtained by the temperature sensor 415. After a temperature value is stable, the initial oil injection command is sent from the electrical control box 402 to the start-stop The starter and stopper 618 opens the two pneumatic push rods 609 synchronously, causing the inner shaft to extend outward quickly, driving the lifting frame 610 and its connected parts to move upward. During the process, the rubber pad 616 quickly pushes the trigger. Because the barrel is placed in the first extended empty tube 3 in advance, the internal temperature of the barrel is basically balanced with that of the first extended empty tube 3 during the waiting time, so that the fuel can be released within the set temperature range. The fuel is then quickly transferred to a corresponding oil storage tank 510 by the oil pipeline 419 and the telescopic pipeline 420. As the amount of fuel continues to increase, the corresponding electronic arc dial 511 senses The corresponding value also gradually increases until the oil filling time is reached. The timer 619 quickly feeds back the signal to the starter and stopper 618, quickly controls the pneumatic push rod 609, retracts its inner shaft, and accelerates the separation of the rubber pad 616 from the trigger. Since the oil delivery distance in the equipment is short, the oil supply is stopped, and the fuel in the corresponding oil storage tank 510 can be stabilized in a short time. The determined elevation value is quickly introduced into the electrical control box 402 by a connected second receiver 515 for temporary storage. After a data statistics, the temperature in the first extended empty pipe 3 is increased again through the above steps and stabilized to the second temperature range, and reset.
