Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, and in particular to a high-strength corrosion-resistant aluminum alloy fuel tank. Background Technology

[0002] Aluminum-based alloys with added amounts of other alloying elements are a type of light metal material. They have high strength, with a specific strength close to that of high alloy steel and a specific stiffness exceeding that of steel. They also have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They are widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.

[0003] When using aluminum alloy fuel tanks, the inlet of the fuel inlet is usually sealed with a sealing cap. When refueling, the sealing cap is removed first, and then the fuel nozzle is inserted to refuel. However, during this process, because the inlet of the fuel inlet is relatively large and faces upward, there is a lack of protection for the inlet during the refueling process. External impurities may enter the inner cavity of the fuel tank through the inlet of the fuel inlet.

[0004] Therefore, this utility model proposes a high-strength, corrosion-resistant aluminum alloy fuel tank to solve the above problems. Utility Model Content

A support platform is provided inside the inlet of the oil inlet pipe, which is used to place auxiliary components. The inlet of the oil inlet pipe is connected to the sealing cap.

[0007] Preferably, the auxiliary component includes an arc-shaped carrier plate, and a protective brush is provided on the inner sidewall of the arc-shaped carrier plate.

[0008] Preferably, the four arc-shaped carrier plates are spliced ​​together to form a ring-shaped carrier plate; The annular carrier plate is placed on a support platform inside the oil inlet pipe.

[0009] Preferably, the protective brush on the inner side of the annular carrier plate forms an annular brush.

[0010] Preferably, the outer wall of the annular carrier plate is adapted to contact the inner wall of the oil inlet pipe.

[0011] Preferably, the auxiliary component further includes a support component, which includes a support slot and a support ring; the support slot is disposed on the inner sidewall of the arc-shaped carrier plate, and the support slot is also arc-shaped; The support slot is adapted to and snaps into the support ring.

[0012] Preferably, auxiliary inclined surfaces are symmetrically provided on the upper and lower sides of the support ring, and the auxiliary inclined surfaces are inclined towards the outer edge of the support ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention relates to a high-strength, corrosion-resistant aluminum alloy fuel tank. A support platform is installed inside the inlet of the fuel inlet pipe, and an auxiliary component, namely an annular carrier plate, is placed on the support platform. This annular carrier plate is formed by splicing four arc-shaped carrier plates. An annular brush is installed on the inner wall of the annular carrier plate. When refueling the tank with a fuel nozzle, the fuel nozzle is inserted into the fuel inlet pipe. At this time, the annular brush on the inner wall of the annular carrier plate contacts the nozzle barrel, and the gap between the fuel inlet pipe and the fuel nozzle is filled by the annular brush. This effectively prevents the entry of external impurities during refueling, thus providing a protective function.

[0014] Based on this, the ring-shaped carrier plate in this solution is formed by splicing, which facilitates later replacement and maintenance work. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a high-strength corrosion-resistant aluminum alloy fuel tank, including a fuel tank body 1 and two protective strips 2 disposed on the fuel tank body 1; An oil inlet pipe 3 is provided on the main body 1 of the oil tank, which is connected to the inner cavity of the main body 1 of the oil tank. A support platform 31 is provided on the inner side of the inlet of the oil inlet pipe 3, which is used to place auxiliary components. The inlet of the oil inlet pipe 3 is connected to the sealing cap 4.

[0019] This design includes a support platform 31 inside the inlet of the oil inlet pipe 3, and an auxiliary component, namely an annular carrier plate, placed on the support platform 31. The annular carrier plate is formed by splicing four arc-shaped carrier plates 501. An annular brush is provided on the inner wall of the annular carrier plate. When refueling the oil tank through the refueling gun, the refueling gun is inserted into the oil inlet pipe 3. At this time, the annular brush on the inner wall of the annular carrier plate contacts the gun barrel of the refueling gun. The gap between the oil inlet pipe 3 and the refueling gun is filled by the annular brush, which has a positive effect on preventing the entry of external impurities during refueling, that is, providing a protective function.

[0020] According to the appendix Figure 2-3 As shown, the auxiliary components include an arc-shaped carrier plate 501, on the inner side wall of which a protective brush 502 is provided; four arc-shaped carrier plates 501 are spliced ​​together to form an annular carrier plate. After the annular carrier plate is placed in the oil inlet pipe 3, it will stay on the support platform 31 in the oil inlet pipe 3, and the outer ring surface of the annular carrier plate will contact the inner side wall of the oil inlet pipe 3. Then, the sealing cap 4 is used to seal the opening of the oil inlet pipe 3.

[0021] From Figure 2 As can be seen, the protective brush 502 on the inner side of the annular carrier plate forms an annular brush, and the inner side of the annular brush forms a circular opening. This circular opening is used for the insertion of the nozzle barrel of the refueling gun. That is, when refueling, first open the sealing cap 4, and then directly insert the nozzle barrel of the refueling gun into the oil inlet pipe 3, and insert the nozzle barrel from the circular opening formed on the inner side of the annular brush. At this time, the annular brush is equivalent to filling the gap between the nozzle barrel and the oil inlet pipe 3, that is, it has a blocking effect on external impurities. After the refueling work is completed, the refueling gun is pulled out, and finally the sealing cap 4 is used to seal the opening of the oil inlet pipe 3.

[0022] Then from the appendix Figure 3As can be seen, the auxiliary components also include a support component, which includes a support slot 601 and a support ring 602. The support slot 601 is located on the inner sidewall of the arc-shaped carrier plate 501, and the support slot 601 is also arc-shaped. The support slot 601 is adapted to engage with the support ring 602. That is, the ring-shaped carrier plate formed by splicing the four arc-shaped carrier plates 501 is supported by the support ring 602. In other words, the four arc-shaped carrier plates 501 are respectively clamped onto the support ring 602. After the four arc-shaped carrier plates 501 are clamped, the four arc-shaped carrier plates 501 will form a ring-shaped carrier plate. The purpose of this is to facilitate the subsequent disassembly, replacement and other maintenance work of the auxiliary components.

[0023] For example, when auxiliary components need to be replaced or disassembled for cleaning after long-term operation, first open the sealing cap 4, and then directly remove the annular carrier plate from the oil inlet pipe 3. After removing the annular carrier plate, if replacement is required, simply replace it with a new auxiliary component. If cleaning is required, to improve the convenience of cleaning and maintenance, disassemble the arc-shaped carrier plates 501 one by one. That is, remove the four arc-shaped carrier plates 501 from the support ring body 602 respectively. First, pull one of the arc-shaped carrier plates 501 outward until the support groove 601 on the inner side of the arc-shaped carrier plate 501 separates from the support ring body 602. The disassembly of the arc-shaped carrier plate 501 is then complete. Then, disassemble the remaining arc-shaped carrier plates 501 in the same way.

[0024] This separation of the four arc-shaped carrier plates 501 and the support ring 602 facilitates thorough cleaning, disperses the overall structure, and allows for better cleaning of specific areas or sections, providing convenience for the cleaning work of the staff.

[0025] After the cleaning work is completed, each of the arc-shaped carrier plates 501 needs to be spliced ​​with the support ring 602, that is, the four arc-shaped carrier plates 501 are spliced ​​and installed one by one on the support ring 602; here we will then refer to the attached Figure 4 As shown, to further improve the ease of operation when engaging the support slot 601 and the support ring 602, this solution provides symmetrical auxiliary inclined surfaces 603 on the upper and lower sides of the support ring 602. These auxiliary inclined surfaces 603 are inclined towards the outer edge of the support ring 602. This means that the thickness of the outer wall edge of the support ring 602 is less than the width of the slot 601. Specifically, when installing the arc-shaped carrier plate 501 onto the support ring 602, the support slot 601 on the inner side of the arc-shaped carrier plate 501 is aligned with the outer wall edge of the support ring 602. Then, the support slot 601 and the support ring 602 are engaged, and finally, the arc-shaped carrier plate 501 is pressed tightly.

[0026] During this process, since the thickness of the outer edge of the support ring 602 is less than the width of the support slot 601, when the support ring 602 is aligned and inserted into the support slot 601, the outer edge of the support ring 602 can more easily enter the support slot 601. The thickness of the support ring 602 is the same as the width of the support slot 601. Then, the remaining arc-shaped carrier plate 501 can be installed in the same way as described above. The assembly of the auxiliary components is then completed. After that, the assembled auxiliary components are placed in the oil inlet pipe 3 and supported by the support platform 31.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
