Description
Technical Field
[0001] The utility model relates to the technical field of cleaning equipment, and particularly relates to a fuel tank cleaning tool. Background Art
[0002] A fuel tank is a container for storing fuel. As the usage time increases, various impurities will gradually accumulate in the fuel tank. Regularly cleaning the inner wall of the fuel tank can effectively remove the carbon deposits and impurities in the fuel tank, thereby helping to improve the overall durability and service life of the fuel tank, reducing the energy efficiency loss caused by deposits, and the potential risk of equipment damage.
[0003] In the prior art, high-pressure gas is mainly introduced into the bottom of the gasoline in the fuel tank through a pipeline to enhance the fuel fluid dynamics effect, increase the turbulence intensity of the gasoline inside the fuel tank, so that the violently fluctuating gasoline exerts an impact force on the carbon deposits and sediments on the inner wall of the fuel tank, and then the gasoline in the fuel tank is discharged to carry away the carbon deposits and sediments originally attached to the inner wall of the fuel tank.
[0004] However, when using the above operations, gasoline will adhere to the outer surface of the pipeline, which not only affects the grip but also brings difficulties to the cleaning work of the pipeline, and will cause secondary pollution to the inside of the fuel tank that needs to be cleaned subsequently during continuous cleaning operations on different fuel tanks. Therefore, this application provides a fuel tank cleaning tool. Summary of the Utility Model

[0031] Embodiment 1:
[0032] As Figure 1 shown, this embodiment provides a fuel tank cleaning tool, which includes an air pipe 1, a limit disk 11, a fuel tank interface fixing disk 21, and a sealing ring 13; one end of the air pipe 1 extends towards the bottom area inside the fuel tank, and the other end of the air pipe 1 is connected to an air pump through a pipeline. A limit disk 11 is sleeved and installed outside the air pipe 1, and a fuel tank interface fixing disk 21 is fixedly installed at the bottom of the limit disk 11. A sealing ring 13 is arranged on the limit disk 11, and the inner side surface of the sealing ring 13 abuts against the outer side surface of the air pipe 1. A plurality of chucks 22 are slidably installed on the outer side surface of the fuel tank interface fixing disk 21, and the end of the chuck 22 abuts against the inner side surface of the fuel tank opening.
[0033] As Figure 1-2 and Figure 4 shown, a plurality of sliding rails 12 are arranged on the limit disk 11, and a magnetic adsorption seat 34 is slidably installed in each sliding rail 12. A magnetic column 23 that can be coupled to the magnetic adsorption seat 34 by magnetic adsorption is fixedly installed on the chuck 22.
[0034] In this embodiment, fasteners can be used to lock the position of the magnetic adsorption seat 34 in the sliding rail 12.
[0035] When using the fuel tank cleaning tool of this application:
[0036] First, install the fuel tank interface fixing disk 21 at the fuel tank opening, adjust the positions of the plurality of magnetic adsorption seats 34 in their respective sliding rails 12, and drive the chucks 22 to extend to abut against the inner side surface of the fuel tank opening by using the magnetic adsorption between the magnetic adsorption seats 34 and the magnetic columns 23.
[0037] Afterwards, connect one end of the air pipe 1 located outside the fuel tank to the air pump. Hold the air pipe 1 and insert it below the gasoline level inside the fuel tank. Start the air pump so that the violently fluctuating gasoline exerts an impact force on the carbon deposits and sediments on the inner wall of the fuel tank, causing them to separate from the inner wall of the fuel tank.
[0038] Finally, drain the gasoline in the fuel tank. As the gasoline drains out completely, the carbon deposits and sediments originally attached to the inner wall of the fuel tank are carried away. During this process, hold the air pipe 1 and pull it out. Use the sealing ring 13 to scrape off the oil stains adhered to the outer side of the air pipe 1. Along with the continuous operation of the air pump, the gasoline remaining in the inner wall of the air pipe 1 is blown back into the fuel tank, reducing the difficulty of holding the pipe and avoiding secondary pollution to the interior of the fuel tank that needs to be cleaned later.
[0039] Among them, the way to keep the chuck 22 in the extended state is to utilize the magnetic attraction between the magnetic seat 34 and the magnetic column 23. In the case of forcibly removing the fixed plate 21 of the fuel tank interface, even if the magnetic seat 34 is not moved, the chuck 22 can be retracted, avoiding damage to the fuel tank opening caused by misoperation and achieving the purpose of anti-fool design.
[0040] Among them, since the chuck 22 does not completely seal the gap between the fixed plate 21 of the fuel tank interface and the fuel tank opening, the high-pressure gas input into the fuel tank can be smoothly discharged, and the internal pressure of the fuel tank will not be too high and cause damage.
[0041] To improve the convenience of tool carrying and use, as Figure 1 shown, a limiting edge protruding outward is provided on the outer side of the bottom of the air pipe 1; the limiting edge plays a role in limiting, avoiding inconvenience to the next use of the tool due to the complete loosening of the air pipe 1; an iron ring is installed on the upper side of the limiting edge, and a magnetic ring capable of magnetically attracting and coupling with the iron ring is installed on the fixed plate 21 of the fuel tank interface; by using the magnetic attraction between the iron ring and the magnetic ring, the relative position of the air pipe 1 and the fixed plate 21 of the fuel tank interface is kept constant, facilitating the carrying of the tool.
[0042] Embodiment 2:
[0043] The features identical to those in Embodiment 1 will not be elaborated here. The different solution in this embodiment from Embodiment 1 is as follows: as Figure 1-3 shown, in this embodiment, a synchronous control ring 31 is sleeved and installed on the outer side of the air pipe 1. The synchronous control ring 31 is arranged on the side of the limiting plate 11 away from the fixed plate 21 of the fuel tank interface. The synchronous control ring 31 is connected to a plurality of magnetic seats 34 through a plurality of connecting rods 33. Both ends of the connecting rod 33 are rotatably connected to the synchronous control ring 31 and the magnetic seat 34 respectively.
[0044] Manually adjust the distance between the synchronous control ring 31 and the limit disk 11, press the synchronous control ring 31 against the limit disk 11, and under the action of the connecting rod 33, drive multiple magnetic suction seats 34 to slide in their respective corresponding slide rails 12. By using the magnetic adsorption between the magnetic suction seats 34 and the magnetic columns 23, synchronously adjust the extension and retraction of multiple chucks 22, with high operation convenience.
[0045] Embodiment Three:
[0046] The features identical to those in Embodiment Two will not be elaborated here. The difference between this embodiment and Embodiment One lies in that: as Figure 1-3 shown, in this embodiment, a plurality of T-shaped columns 35 are fixedly installed at the end of the synchronous control ring 31, and a slot Ⅰ and a slot Ⅱ for inserting the T-shaped columns 35 are respectively arranged on the limit disk 11 and the fuel tank interface fixing disk 21; the T-shaped columns 35 play a role in limiting, ensuring the center alignment of the synchronous control ring 31 and the limit disk 11.
[0047] In order to enable multiple chucks 22 to automatically eject, as Figure 2-3 shown, a ring cover 14 is detachably and fixedly installed at the end of the slot Ⅰ on the limit disk 11, and a tension spring 36 is fixedly installed between the ring cover 14 and the T-shaped column 35; under the action of the tension spring 36, the synchronous control ring 31 always has a tendency to approach the limit disk 11, enabling multiple chucks 22 to automatically eject until they are tightly pressed against the inner side surface of the fuel tank opening.
[0048] Among them, rings are respectively welded at both ends of the tension spring 36, and the two rings are respectively detachably and fixedly connected to the ring cover 14 and the T-shaped column 35, improving the disassembly convenience of the tension spring 36 and facilitating the subsequent cleaning and maintenance of each component of the tool;
[0049] The above description is only for the preferred embodiments of the present application and the description of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.
[0050] Except for the technical features described in the specification, the remaining technical features are known to those skilled in the art. To highlight the innovative features of the present utility model, the remaining technical features will not be elaborated here.
