Description

Technical Field

[0001] The present invention relates to the technical field of fuel dispenser detection, and specifically, it is a fuel dispenser verification and metering device. Background Art

[0002] Fuel dispensers have developed along with the development of automobiles and road traffic. They are the sales terminals of the refined oil retail industry and are metering devices for sales settlement. The fuel dispenser is controlled by a computer main board to discharge oil, making refueling convenient, fast, and accurate. At the same time, the fuel dispenser is combined with network communication management and IC cards, enabling the fuel dispenser to have functions such as network management, convenient payment, and value-added services on the basis of oil transportation and metering. When the fuel dispenser is in use, it needs to be verified and metered to ensure the accuracy of refueling.

[0003] Based on the above, the inventor of the present invention found that the existing ones mainly have the following deficiencies. For example, when the oil gun of the existing fuel dispenser is inserted into the detection barrel for refueling, the gasoline is sprayed into the detection barrel and generates an impact, causing the gasoline to generate bubbles and float upward due to the air pressure being inserted back. The bubbles accumulate and float to the upper end of the gasoline, resulting in measurement deviation when the gasoline is being metered due to the influence of the bubbles. Summary of the Invention

[0004] In view of the above problems, the present invention provides a fuel dispenser verification and metering device.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions: A fuel dispenser verification and metering device, the structure of which includes a detection barrel, an oil inlet hopper, and a detection structure. The bottom of the detection barrel is supported by a support frame. The top of the detection barrel is connected to the oil inlet hopper, and the bottom of the detection barrel is connected to an oil outlet pipe. The detection structure is arranged at the top of the detection barrel. A oil guiding structure is arranged in the middle of the detection barrel. The top end of the oil guiding structure is fixedly connected to the inner side of the oil inlet hopper. A bubble intercepting structure is fixedly installed on the inner side of the detection barrel.

[0006] Further, the bubble intercepting structure is provided with an installation ring. The bottom of the inner side of the installation ring is provided with a bubble intercepting block. The bubble intercepting block is internally provided with a plurality of through holes. The through holes are arranged in a circumferential arrangement around the end face of the bubble intercepting block. The top of the through holes is provided with a conical bubble intercepting net. The bottom end face of the through holes is provided with a wavy protrusion. The inner upper end of the installation ring is provided with three layers of filter meshes. The gasoline can flow upward through the through holes, and the bubbles in the gasoline can be concentrated at the bottom of the bubble intercepting block.

[0007] Further, the pore sizes of the filter meshes in the filter mesh are such that the bottom layer filter mesh is larger than the middle layer filter mesh and the middle layer filter mesh is larger than the upper layer filter mesh. By filtering the bubbles through the three layers of filter meshes, small bubbles can be intercepted.

[0008] Further, the support structure is provided with two mounting seats. Between the two mounting seats, there are two clamping blocks. The clamping block at the front end is fixedly connected to the two mounting seats, while the clamping block at the rear end is slidably engaged with the two clamping blocks. Moreover, the clamping block at the rear end is provided with a servo motor and an infrared sensor. The two clamping blocks are threadedly connected by a threaded rod, and the servo motor is meshed with the threaded rod.

[0009] Further, the oil guiding structure is provided with a conduit. The top of the conduit is provided with a connecting ring. The bottom of the conduit is in a herringbone shape, and the two ends of the bottom of the conduit are respectively connected to two flow - buffering heads. The herringbone - shaped conduit is used to split the gasoline flow.

[0010] Further, the outer side of the connecting ring is provided with a groove which is fitted and connected with the inner side of the fuel inlet hopper. The inner side of the connecting ring is provided with an inner groove. The top end of the inner groove is provided with an inclined slope. The bottom of the inner groove is fixedly connected to the conduit. Through the 45 - degree inclined slope of the inner groove, it is convenient to insert the fuel gun of the fuel dispenser into the inner groove in the connecting ring for connection, and the fuel gun fits against the inner side of the connecting ring, which can prevent air from entering the detection barrel.

[0011] Further, the inner top of the flow - buffering head is provided with a fixed card slot which is connected to the bottom of the conduit. The inner side of the flow - buffering head is surrounded by eight flow - guiding vanes, allowing the gasoline to flow downward along the end face of the flow - guiding vanes.

[0012] Further, the detection structure is provided with two connecting pipe heads. The two connecting pipe heads are respectively arranged at the bottom of the fuel inlet hopper and the top end of the detection barrel. A detection pipe is between the two connecting pipe heads. The detection pipe is made of acrylic material, and the outer end face of the detection pipe is provided with scales. The top of the detection pipe is provided with a liquid level detector. Through the acrylic - material detection pipe, the internal gasoline liquid level can be directly seen, and the liquid level of the gasoline is detected according to the scales on the outer end of the detection pipe. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the perforations in the bubble - intercepting structure enable the gasoline to flow upward, allowing the bubbles in the gasoline to gather at the bottom of the bubble - intercepting block. Then, the bubble - intercepting net intercepts the bubbles, and the three - layer filter screens filter the bubbles in layers, which can intercept fine bubbles and prevent the bubbles from floating on the liquid surface of the gasoline and affecting the detection.

[0014] In the present invention, the fuel gun of the fuel dispenser is inserted into the inner groove in the connecting ring for connection, and the fuel gun fits against the inner side of the connecting ring, which can prevent air from entering the detection barrel and reduce the generation of bubbles in the gasoline.

[0015] The present invention utilizes eight flow guiding vanes on the inner side of the flow retarder head to guide the gasoline, allowing the gasoline to flow downward along the end surface of the flow guiding vanes, reducing the generation of bubbles caused by the impact when the gasoline enters the interior of the detection barrel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1: Please refer to Figures 1 - 5 , the specific embodiments of the present invention are as follows: Its structure includes a detection barrel 1, an oil inlet hopper 2, and a detection structure 3. The bottom of the detection barrel 1 is supported by a support frame 4. The top of the detection barrel 1 is connected to the oil inlet hopper 2, and the bottom of the detection barrel 1 is connected to an oil outlet pipe 5. The detection structure 3 is arranged at the top of the detection barrel 1. A oil guiding structure 21 is provided at the middle position inside the detection barrel 1. The top end of the oil guiding structure 21 is fixedly connected to the inner side of the oil inlet hopper 2. A bubble intercepting structure 22 is fixedly installed on the inner side of the detection barrel 1.

[0027] The bubble intercepting structure 22 is provided with an installation ring 211. At the inner bottom of the installation ring 211, there is a bubble intercepting block 222. Inside the bubble intercepting block 222, there are a number of through holes 224. The through holes 224 are arranged in a ring around the end face of the bubble intercepting block 222. At the top of the through hole 224, there is a conical bubble intercepting net 225. At the bottom end face of the through hole 224, there are wavy protrusions. At the upper inner side of the installation ring 211, there are three layers of filter meshes 223. Through the through holes 224, gasoline can flow upward, enabling the bubbles in the gasoline to gather at the bottom of the bubble intercepting block 222, and then the bubble intercepting net 225 intercepts the bubbles.

[0028] The mesh sizes of the filter meshes 223 in the three layers are such that the bottom layer filter mesh 223 is larger than the middle layer filter mesh 223, and the middle layer filter mesh 223 is larger than the upper layer filter mesh 223. By filtering the bubbles in three layers through the three - layer filter meshes 223, fine bubbles can be intercepted, preventing the bubbles from floating on the liquid surface of the gasoline and affecting the detection.

[0029] The support structure 23 is provided with two mounting seats 231. Between the two mounting seats 231, there are two clamping blocks 232. The clamping block 232 at the front end is fixedly connected to the two mounting seats 231, while the clamping block 232 at the rear end is slidably mated with the two clamping blocks 232. The clamping block 232 at the rear end is provided with a servo motor 234 and an infrared sensor 235. The two clamping blocks 232 are threadedly connected through a threaded rod 233, and the servo motor 234 is meshed with the threaded rod 233. Based on the above embodiments, the specific working principle is as follows: When calibrating the metering of the fuel dispenser, the fueling volume in the fuel dispenser can be set to match the capacity of the detection barrel 1. The fuel gun is inserted into the fuel inlet hopper 2. The servo motor 234 can be controlled to work and engage with the threaded rod 233 through the induction of the infrared sensor 235, so that the threaded rod 233 is in threaded cooperation with the clamping block 232 and drives it to move towards the position of the other clamping block 232. The fuel gun of the fuel dispenser is fixedly supported by the two clamping blocks 232, avoiding the shaking of the fuel gun inserted in the fuel inlet hopper 2, preventing external air from entering the interior of the detection barrel 1, and reducing the bubbles generated by the gasoline when adding gasoline into the detection barrel 1. Then, it is connected to the oil guiding structure 21 through the fuel inlet hopper 2, and the gasoline is conveyed to the bottom end inside the detection barrel 1, avoiding the large impact caused by the gasoline flowing down to the bottom of the detection barrel 1 from top to bottom, thereby reducing the generation of bubbles. When bubbles are generated in the gasoline located in the detection barrel 1, the gasoline can flow upward through the perforation 224 in the bubble intercepting structure 22, enabling the bubbles in the gasoline to concentrate at the bottom of the bubble intercepting block 222, and then the bubble intercepting net 225 intercepts the bubbles, and the three-layer filter screen 223 filters the bubbles in layers, intercepting the fine bubbles and preventing the bubbles from floating on the liquid surface of the gasoline and affecting the detection.

[0030] Embodiment 2: Please refer to Figures 6 - 8 , the specific embodiments of the present invention are as follows: The oil guiding structure 21 is provided with a conduit 211. A connecting ring 212 is provided at the top of the conduit 211. The bottom of the conduit 211 is in a herringbone shape, and the two ends of the bottom of the conduit 211 are respectively connected to two flow retarder heads 213. The herringbone-shaped conduit 211 diverts the gasoline, reducing the discharge volume of the gasoline and enabling the gasoline to slowly flow into the interior of the detection barrel 1.

[0031] A groove 2121 is provided on the outer side of the connecting ring 212 and is in fit connection with the inner side of the fuel inlet hopper 2. An inner groove 2122 is provided on the inner side of the connecting ring 212. The top end of the inner groove 2122 is provided with an inclined surface inclined at 45 degrees. The bottom of the inner groove 2122 is fixedly connected to the conduit 211. Through the inclined surface of the inner groove 2122 inclined at 45 degrees, it is convenient to insert the fuel gun of the fuel dispenser into the inner groove 2122 in the connecting ring 212 for connection, and the fuel gun fits against the inner side of the connecting ring 212, which can prevent air from entering the detection barrel 1 and reduce the generation of bubbles in the gasoline.

[0032] A fixed card slot 2131 is provided on the inner side of the top of the flow retarder head 213 and is connected to the bottom of the conduit 211. Eight guide vanes 2132 are provided around the inner side of the flow retarder head 213, enabling the gasoline to flow downward along the end surface of the guide vanes 2132 and reducing the bubbles generated when the gasoline enters the interior of the detection barrel 1.

[0033] The detection structure 3 is provided with two connecting pipe heads 31, and the two connecting pipe heads 31 are respectively arranged at the bottom of the oil inlet hopper 2 and the top of the detection barrel 1. A detection pipe 32 is arranged between the two connecting pipe heads 31. The detection pipe 32 is made of acrylic material, and a scale is arranged on the outer end face of the detection pipe 32. A liquid level detector 33 is arranged at the top of the detection pipe 32. The gasoline liquid level inside can be directly seen through the acrylic detection pipe 32, and the liquid level detector 33 is used to detect and display the gasoline liquid level.

[0034] Based on the above embodiments, the specific working principle is as follows: Through the inclined plane of the inner groove 2122 at an angle of 45 degrees, it is convenient to insert the oil gun of the fuel dispenser into the inner groove 2122 in the connecting ring 212 for connection, and the oil gun fits against the inner side of the connecting ring 212, which can prevent air from entering the detection barrel 1 and reduce the generation of bubbles in the gasoline. Then, the gasoline is shunted by the herringbone-shaped conduit 211 to reduce the displacement of the gasoline, allowing the gasoline to flow slowly into the interior of the detection barrel 1. Finally, the gasoline is guided by the eight guide vanes 2132 on the inner side of the flow retarder head 213, and the gasoline flows downward along the end face of the guide vanes 2132, reducing the bubbles generated by the impact when the gasoline enters the interior of the detection barrel 1, which is convenient for assisting the inspectors to detect the fuel dispenser. The detection structure 3 can detect the gasoline liquid level through the scale on the outer end of the detection pipe 32, and at the same time, the liquid level detector 33 can be used to detect and display the gasoline liquid level, improving the accuracy of the verification and measurement of the fuel dispenser.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0036] Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
