The fuel tank cleaning machine 2 consists of a bracket 21, a motor 22, a suction pipe 23, a circuit control box 24, and a return pipe 25. The motor 22 is disposed inside the bracket 21, the suction pipe 23 is disposed on one side of the bracket 21, and the return pipe 25 is disposed on the other side of the bracket 21. The circuit control box 24 is disposed on the top of the bracket 21. The ends of the suction pipe 23 and the return pipe 25 both penetrate through holes opened on the surface of the fuel tank 1 to the fuel tank 1. Internally, the fixing fixture 3 consists of a locking assembly 31, a support 32, and a suction cup 33. The fixing fixture 3 secures the connection between the oil extraction pipe 23, the oil return pipe 25, and the fuel tank 1. The support 32 is fixed to the bottom end of the suction cup 33, using suction to fix the fixing fixture 3 at any position on the surface of the fuel tank 1. The locking assembly 31 is located at the other end of the support 32. This fixed fixture 3 design improves upon the previous method of cleaning the fuel tank using a fuel tank cleaning machine, where the ends of the oil extraction pipe 23 and the oil return pipe 25 penetrated into the interior of the fuel tank 1, causing issues with the connection between the oil extraction pipe 23 and the oil return pipe 25. The inability to secure the fuel tank 1 to the fuel tank cleaning machine 2 poses a risk of the fuel tank 1 falling off during normal transport by the fuel extraction pipe 23 and return pipe 25, thus affecting the cleaning efficiency of the fuel tank 1. To address this, a fixing fixture 3 is installed at the connection between the fuel tank cleaning machine 2 and the fuel tank 1. During the cleaning process by the fuel tank cleaning machine 2, the fixing fixture 3 secures the fuel extraction pipe 23 and return pipe 25 to the fuel tank 1, ensuring their stability during internal transport and allowing the fuel tank 1 to pass through the cleaning process smoothly. During normal operation of machine 2 during cleaning, support 32 has a cylindrical structure. The locking assembly 31 consists of locking block A311, locking block B312, and elastic assembly 313. Locking block A311 is located on the side of locking block B312. The end of locking block A311 and the end of locking block B312 are in a locking state. Elastic assembly 313 is located between the locking points of the ends of locking block A311 and locking block B312. The cross-section of locking block A311 is an arc-shaped structure, and the cross-section of locking block B312 is an arc-shaped structure. A coarse filter tank is installed on one side of support 21, and a fine filter tank is installed on the other side of support 21.

[0021] In this embodiment, preferably, the elastic component 313 consists of a crossbar 3131, a torsion spring 3132, and a movable groove 3133. The movable groove 3133 is formed on the inner side of the end of the elastic component 313, and the crossbar 3131 passes through the inner side of the movable groove 3133. The two ends of the crossbar 3131 are respectively fixed to the inner side of the end of the locking block B312. The elastic component 313 is used for the connection between the locking blocks A311 and B312, facilitating connection with the sucker pipe 23 and the return pipe 2. 5. Fixed position: Torsion spring 3132 is sleeved on the surface of crossbar 3131 and located inside movable groove 3133. Both ends of torsion spring 3132 are fixed to the inner wall of movable groove 3133. Crossbar 3131 has a cylindrical structure. When the locking block B312 is pried outward by external force, the locking block B312 rotates around the through crossbar 3131 as the center, and the torsion spring 3132 deforms. When the locking block B312 is released, it rebounds through the torsion of torsion spring 3132.

[0022] The working principle and usage process of this utility model are as follows: During the cleaning process of fuel tank 1, the fuel inside fuel tank 1 is first extracted through the oil extraction pipe 23 and sent to the coarse filter tank for preliminary filtration to remove large particles of impurities and water. The diesel fuel after primary filtration is sent to the fine filter tank for deep filtration to remove fine particles of impurities. The cleaned oil after two stages of filtration is sprayed at a certain pressure through a high-pressure nozzle onto the side cavity and dead corners of fuel tank 1 to fully agitate the impurities inside fuel tank 1 and to circulate and filter, ensuring the cleanliness of the fuel tank and its interior. The diesel fuel is highly clean. During the process of fixing the end of the oil extraction pipe 23 and the end of the oil return pipe 25 to the fuel tank 1 through the fixing fixture 3, the fixing fixture 3 is first attached to any position on the surface of the fuel tank 1 by the suction cup 33. Then, the locking block B312 of the locking assembly 31 is bent to the side, so that the end of the locking block B312 is flipped outward. Then, the end of the oil extraction pipe 23 or the end of the oil return pipe 25 is inserted into the inside of the locking block A311 and the locking block B312. Then, the locking block B312 is released to fix the oil extraction pipe 23 and the oil return pipe 25.
