[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example 1: Figure 1 The diesel filling auxiliary device shown includes an outer disc, a conical plate, a grid, a guide pipe and a disc, wherein the conical plate is arranged below the outer disc, the outer disc is a circular ring structure, the grid is arranged below the conical plate, the bottom of the grid is connected to the disc, a circular hole is arranged in the center of the disc, the circular hole is connected to a straight pipe, and the guide pipe is arranged in the straight pipe.

[0022] The guide pipe includes an upper guide pipe and a lower guide pipe connected in a socket-type manner. A circular ring matching the straight pipe is provided on the top of the upper guide pipe. A circular ring matching the upper guide pipe is provided on the top of the lower guide pipe, and the lower part of the lower guide pipe is fully welded and sealed. The upper guide pipe and the lower guide pipe are respectively provided with circular holes symmetrically and staggered left and right along the center line. The outer disc is also connected to a static electricity conduction device.

[0023] Example 2: Figure 1 The diesel filling auxiliary device shown is made of aluminum, and the static electricity value is controlled within <0.03Ω. The static electricity conduction resistance of the product is tested to be <0.03Ω.

[0024] 1. The outer disc for fixing the fuel gun is made of 12 aluminum rods and has a diameter of 28.5 cm. It is just right for fixing the fuel gun to prevent the fuel gun from accidentally falling from the tanker to the ground and damaging the fuel gun. At the same time, an external static conductive device is welded;

[0025] 2. Use 3 40X4mm aluminum plates to form a cone to connect the lower disc. The cone height is 14cm, the outer diameter of the disc is 26cm, and the inner diameter is 24.5cm, which allows the auxiliary device to enter through the oil tank metering port, solving the problem of serious mismatch between the guide pipe and the tanker metering port;

[0026] 3. Weld an aluminum mesh with a diameter of 24.5cm, a height of 11cm, and a specification of 10 meshes, and then weld a 245X3mm diameter disc at the bottom, which effectively solves the problem of gas discharge in the tank during oil loading and unloading, while avoiding splashing oil. At the same time, it can also allow the remaining oil after the refueling gun is finished to flow into the tank along the mesh;

[0027] 4. Open two circular holes with a diameter of 60mm in the center of the disc, weld a 100mm long straight pipe to stabilize the guide pipe, 30mm away from the edge, and 6.5cm between the two straight pipes, so that the two guide pipes can be placed in the tank truck, and the guide pipes can be stabilized without shaking. During the oil filling process, the guide pipe is inserted into the straight pipe, which effectively solves the shaking phenomenon of the guide pipe during refueling.

[0028] 5. Make two spigot-and-socket type flow guide pipes, each of which is made as follows: (1) The upper part of the spigot-and-socket type flow guide pipe is a 40mm aluminum tube with a length of 800mm. It is symmetrical along the center line and staggered left and right. 20 holes are opened every 150mm. The outer edge of the upper part of the pipe is welded with a 65mm outer diameter and a 40mm inner diameter circular ring, which is easy to insert into the 60mm aluminum tube and will not fall into the tank car. The lower part is welded with a 33mm inner diameter and a 40mm outer diameter circular ring in the 40mm aluminum tube. (2) Make a 32mm aluminum tube with a length of 900mm. It is symmetrical along the center line and staggered left and right. 20mm holes are opened every 150mm. The upper part of the aluminum tube is welded with a 38mm outer diameter and a 32mm inner diameter circular ring. The lower part is fully welded and sealed. After the sealing is completed, 20mm circular holes are opened symmetrically near the lower part of the pipeline.

[0029] 6. Insert the 32mm aluminum tube into the 40mm aluminum tube, and then into the 60mm diameter aluminum tube, which can meet the requirements of any height of the tank truck for oil delivery, and also meet the requirements of the specification that the oil delivery crane pipe extends into the bottom of the tank truck during filling and delivery. The diversion hole is opened in the guide pipe to reduce the oil delivery speed due to the increase in the height of the oil product during loading, or to prevent roof caving accidents caused by too high flow rate.

[0030] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
