[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0031] In the related art, in the field of aerospace fuel, generally, the use of aviation fuel is often done manually, requiring manual handling of sample barrels for single use, which is prone to the risk of oil sample leakage caused by excessive manual operations. At the same time, static electricity in aviation fuel is easily generated by fuel impact, molecular friction, etc. during the sampling process, which can easily cause dangerous accidents.

[0032] Based on this, the present application provides a sample loading system 10, as shown in the attached Figure 1 As shown, the sampling device 100 includes an oil storage barrel 200. The oil storage barrel 200 is grounded. The sampling device 100 includes a sample storage barrel 110, a conductive component 120, a sampling pipeline 130 and a switch valve 140.

[0033] The sample storage barrel 110 is used to store the fuel sample.

[0034] The conductive component 120 includes a first conductive end 121, a second conductive end 122, and a conductive wire 123. The first conductive end 121 is conductively disposed on the sample storage barrel 110. The second conductive end 122 is conductively disposed on the oil storage barrel 200. The conductive wire 123 is conductively connected to the first conductive end 121 and the second conductive end 122, so that the sample storage barrel 110 is electrostatically grounded through the oil storage barrel 200.

[0035] The sampling pipe 130 is connected between the sample storage barrel 110 and the oil storage barrel 200. The switch valve 140 is disposed in the sampling pipe 130, so that the switch valve 140 includes a passage state that makes the sampling pipe 130 connected and a closed state that makes the sampling pipe 130 at least partially disconnected.

[0036] It is understandable that, by setting the conductive component 120, the static electricity in the sample storage barrel 110 can be released at any time to avoid safety accidents caused by the existence of static electricity. Furthermore, by the cooperation of the sampling pipe 130, the switch valve 140 and the oil storage barrel 200, the operator can achieve oil sampling by only controlling the opening and closing state of the switch valve 140, which is easy to operate, and the sampling pipe 130 can be accurately connected to the sample storage barrel 110, avoiding the sampling instability caused by manual holding of the pipe.

[0037] It should be noted that the shape of the oil storage barrel 200 can be cylindrical, prismatic, etc., and no excessive restrictions are imposed here.

[0038] In some embodiments, the sample storage barrel 110 may have a barrel height of 10 cm to 50 cm. In this way, the sample storage barrel 110 of this size is suitable for the operator to carry, which is convenient for replacing a new barrel and improves the replacement efficiency.

[0039] In one example, the height of the sample storage barrel 110 may be 15 cm to 45 cm.

[0040] In another example, the height of the sample storage barrel 110 may be 15 cm to 30 cm.

[0041] In some embodiments, the height of the sample storage barrel 110 may be 15 cm, 20 cm, 25 cm, 30 cm, etc., without further limitation herein.

[0042] In order to enhance the stability and sealing of the sampling process, in combination with any of the above-mentioned embodiments of the sample storage barrel 110, as shown in the attached Figure 2 As shown, the sample storage barrel 110 includes a barrel body 111 and a barrel cover body 112. A first opening is provided on the barrel cover body 112. The first opening is plugged into and matched with the sampling pipe 130, so that the sampling pipe 130 is connected to the sample storage cavity in the sample storage barrel 110. In this way, it can be understood that the size of the first opening is smaller than the barrel cover body 112. In this way, the barrel cover body 112 can block the fuel sample to prevent its evaporation loss or avoid other foreign matter from entering and affecting the quality inspection. Furthermore, the edge of the first opening can form a certain support effect on the sampling pipe 130, reducing the pressure on the barrel body 111 and affecting the supporting performance of the barrel body 111.

[0043] In some embodiments, one of the barrel cover body 112 and the sampling pipe 130 is provided with a first matching portion, and the other is provided with a sealing portion. The first matching portion is fixedly connected with the sealing portion, so that the first opening is sealed and matched with the sampling pipe 130. In this way, through the sealing cooperation of the first matching portion and the sealing portion, the fuel gas near the mouth of the sampling pipe 130 will not overflow by climbing the side wall of the barrel cover body 112, thereby causing environmental pollution and raw material loss.

[0044] It should be noted that the first matching portion and the connecting portion can be the matching of the groove and the sealing ring, or the clamping and limiting matching of the groove and the convex portion, etc., and no excessive limitation is given here. At the same time, the connection between the barrel cover body 112 and the barrel body 111 can be obtained by welding or stamping.

[0045] In combination with any of the above-mentioned embodiments of the sample storage barrel 110, in combination with the attached Figure 2 and attached Figure 3 As shown, the sample storage barrel 110 further includes a cover 113, which cooperates with the first opening to close the sample storage barrel 110. It is understandable that when the fuel sample in the sample storage barrel 110 is filled to a preset capacity, the sampling pipe 130 can be separated from the first opening, and then the first opening can be closed by the cover 113 to prevent fuel leakage.

[0046] It should be noted that the cooperation between the cover member 113 and the first opening may be, but is not limited to, a snap fit, or a covering fit, etc., which is not further limited herein.

[0047] In a specific implementation scheme, see Figure 1 and Figure 2As shown, the sample storage barrel 110 also includes a mounting body 114 protruding from the plane where the barrel cover body 112 is located. The mounting body 114 is arranged around the first opening. The cover 113 is plugged into and matched with the mounting body 114 so that the cover 113 is fitted with the first opening. In this way, through the arrangement of the mounting body 114, it is convenient for the cover 113 to be accurately aligned with the mounting body 114, thereby improving the efficiency of disassembly and assembly.

[0048] In order to further improve the fixing effect between the cover 113 and the mounting body 114, in some embodiments, one of the inner side wall of the mounting body 114 and the cover 113 is provided with a second matching portion, and the other is provided with a connecting portion. The mounting body 114 is fixedly connected to the cover 113 by the fixed matching of the connecting portion and the second matching portion. It should be noted that the connecting portion and the second matching portion can be a magnetic fixed matching, or a screw fixed matching, a snap fixed matching, etc., which are not too limited here. In this way, the fixed matching effect of the cover 113 and the mounting body 114 can be strengthened by the fixed matching of the connecting portion and the second matching portion, thereby improving the stability of the fuel sample storage.

[0049] Specifically, in one example, Figure 2 and Figure 3 As shown, the second matching portion is provided with an internal thread structure 1131. The connecting portion is provided with an external thread structure 1141. That is, the second matching portion and the connecting portion are screwed and fixed by screwing the internal thread structure 1131 and the external thread structure 1141. In this way, the screw connection is used to achieve the matching and fixing, which is conducive to achieving stable fixing and not easy to reset; at the same time, the structure is simple and easy to set, which is conducive to improving processing efficiency.

[0050] In combination with any of the above-mentioned embodiments of the sample storage barrel 110, see the attached Figure 1 As shown, the sample storage barrel 110 further includes a handle 115, and the handle 115 is disposed on the barrel cover body 112. It can be understood that the arrangement of the handle 115 makes it convenient for the operator to disassemble and assemble, thereby optimizing the operator's operating experience.

[0051] It should be noted that the connection method between the handle 115 and the barrel cover body 112 can be, but is not limited to, welding, magnetic attraction, or snap-on connection.

[0052] In one example, the handle 115 is welded and fixed to the barrel cover body 112. In this way, the processing is convenient, the structure is simple, and the processing cost is reduced.

[0053] In combination with any embodiment of the above-mentioned switch valve 140, the sampling device 100 may also be provided with a pressure detection member, which is arranged in the sampling pipeline 130 to detect the flow rate pressure in the sampling pipeline 130. When the flow rate pressure exceeds a preset level, the controller deploys a corresponding warning instruction. Further, the switch valve 140 may also include an adjustment state so that the operator or the controller can adjust the flow rate of the switch valve 140 according to the flow rate pressure.

[0054] Furthermore, in the above embodiment, the diameter of the first opening is 20 mm to 80 mm. In this way, this size is optimally matched with the sampling pipe 130 and will not be too large to cause fuel vapor to overflow.

[0055] In some embodiments, the diameter of the first opening is 30 mm to 70 mm.

[0056] In some other embodiments, the diameter of the first opening is 40 mm to 70 mm.

[0057] In one example, the diameter of the first opening is 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, etc., and no further limitation is given here.

[0058] In some embodiments, one end of the conductive wire 123 is detachably connected to the outer wall of the sample storage barrel 110. It should be noted that the detachable connection may be, but is not limited to, a clamping, a snap connection, etc., which are not limited here. In this way, the conductive wire 123 and the sample storage barrel 110 can be replaced at any time through the detachable connection, thereby improving the efficiency of assembly and disassembly.

[0059] In combination with any of the above-mentioned embodiments of the sampling pipe 130, the sampling pipe 130 can also be retractable to facilitate the disassembly of the sampling pipe 130 and the sample storage barrel 110. Specifically, the sampling pipe 130 includes an extended state and a contracted state. When the sampling pipe 130 is in the extended state, one end of the sampling pipe 130 is plugged into and matched with the first opening. When the sampling pipe 130 is in the contracted state, one end of the sampling pipe 130 is telescopically separated from the first opening. That is, the end of the sampling pipe 130 adopts a telescopic design, so that the sampling pipe 130 can be telescopically matched with the first opening to achieve disassembly and assembly, thereby improving the disassembly and assembly efficiency.
