[0020] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0021] like Figure 1 , 2As shown, a fuel tank of a refrigerated container of the present invention comprises a box body 10, a fuel tank cover 20, and a shield 30; the box body 10 is a hollow structure surrounded by plates, and its inner cavity is used to contain fuel, and the shield 30 is cylindrical. In a preferred embodiment, the shield 30 is set to a cylindrical structure, which comprises a first end 301 and a second end 302 opposite to the first end 301. The shield 30 is installed on the wall plate 11 at the top of the box body 10, and its first end 301 extends into the inner cavity of the box body 10 and is spaced a certain distance from the wall plate 11 in the height direction, so that the shield 30 can extend a certain length in the inner cavity of the box body 10. Roughly, the shield 30 extending inside the box body 10 accounts for about one third of the overall height of the inner cavity of the box body 10; the first end An end plate 31 is fixed at 301, and the end plate 31 covers the first end 301 of the shield 30, so that the first end 301 of the shield 30 forms a blind end, and the second end 302 of the shield 30 extends to the outer surface of the wall plate 11 of the box body 10, and the second end 302 of the shield 30 forms an oil filling port at the outer surface of the box body 10, and a plurality of through holes are provided on the portion of the shield 30 located on the inner side of the wall plate 11 of the box body 10; the tank cap 20 is connected to the second end 302 of the shield 20 or the wall plate 11 of the box body 10, and its cover is on the outside of the oil filling port, and a locking assembly 40 is also provided on the box body 10, and the locking assembly 40 is used to lock the tank cap 20 on the shield 30 or the box body 10 to prevent the tank cap 20 from detaching from the oil filling port.

[0022] During the transshipment of the refrigerated container, the locking assembly 40 is used to lock the tank cap 20 to the protective cover 30 or the box body 10 to prevent the tank cap 20 from being disassembled, thereby preventing the fuel inside the box body 10 from being stolen; even if the locking assembly 40 is damaged artificially, since the protective cover 30 is fixed on the wall panel 11 of the box body 10, the interior of the protective cover 30 is set as a blind end, and the conduit cannot be extended to a deeper position of the inner cavity of the box body 10, and the fuel inside the box body 10 cannot be discharged, further preventing the fuel from being stolen. In addition, a through hole is set on the part of the protective cover 30 located inside the box body 10, so that fuel can be normally added to the inside of the box body 10 through the oil filling port, ensuring that the fuel tank can be used normally.

[0023] It should be pointed out that the size of the through hole opened on the above-mentioned shield 30 is relatively small to prevent the conduit from extending into a deeper position inside the tank 10. Specifically, the through hole includes a plurality of circular holes 311 opened on the end plate 31 and a long hole 32 opened on the side wall of the shield 30, so as to allow fuel to pass through when fuel is added to the tank 10.

[0024] In a preferred embodiment, a mounting hole 12 is provided on the wall plate 11 of the box body 10, the shield 30 is inserted into the mounting hole 12, and the outer periphery of the shield 30 is welded and fixed to the periphery of the mounting hole 12 to ensure that the two are in a sealed state to prevent fuel from leaking from the shield 30 and the periphery of the mounting hole 12, the second end 302 of the shield 30 protrudes from the outer surface of the wall plate 11 of the box body 10, and the fuel tank cap 20 is screwed on the second end 302 of the shield 20 by screwing; an insert is provided on the inner surface of the fuel tank cap 20 The second end 302 of the protective cover 30 is inserted into the plug-in slot 21. An internal thread can be provided on the outer wall of the plug-in slot 21, and an external thread can be provided on the periphery of the protective cover 30. The external thread cooperates with the internal thread to screw the fuel tank cap 20 on the second end 302 of the protective cover 30, and the second end 302 of the protective cover 30 is inserted into the plug-in slot 21. At the same time, a sealing ring 22 is clamped between the inner wall of the plug-in slot 21 and the second end 302 of the protective cover 30 to seal the gap between the protective cover 30 and the fuel tank cap 20. In other embodiments, the tank cap 20 may be connected to the second end 302 of the shield 30 by snapping. Of course, the tank cap 20 may be connected to the second end 302 of the shield 30 by other connection methods, or the tank cap 20 may be connected to the box body 10 so that the tank cap 20 can cover the oil filling port. In short, the tank cap 20 is fixed to the second end 302 of the shield 30 or the wall panel 11 of the box body 10 in a detachable manner so that the tank cap 20 can be opened and fixed during operation.

[0025] The above-mentioned locking assembly 40 includes a pressure plate 41 and a padlock 43. One end of the pressure plate 41 is pivotally connected to the box body 10, and the other end is sealed on the outside of the fuel tank cover 20. The other end of the pressure plate 41 is locked to the box body 10 or the fuel tank cover 20 by the padlock 43. When the padlock 43 is not opened, the fuel tank cover 20 cannot be opened because the pressure plate 41 is placed on the outside of the fuel tank cover 20. A boss 23 is provided on the outer surface of the fuel tank cover 20, and a lock hole 24 is provided on the boss 23 extending from one side to the other side. A through groove 411 is provided at the other end of the pressure plate 41. When the other end of the pressure plate 41 is placed on the outer side of the fuel tank cover 20, the boss 23 passes through the through groove 411 and is placed on the outer side of the pressure plate 41, especially the lock hole 24 on the boss 23 is placed on the outer side of the pressure plate 41, and the padlock 43 passes through the lock hole 24. After the padlock 43 is locked, the pressure plate 41 cannot swing relative to the box body 10, and then the fuel tank cover 20 is sealed and locked by the pressure plate 41. In order to facilitate the installation of the pressing plate 41, a mounting seat 42 is fixedly connected to the box body 10, and one end of the pressing plate 41 is pivoted to the mounting seat 42 through a pivot 421, and the central axis of the pivot 421 is parallel to the wall plate 11 of the box body 10, that is, after the padlock 43 is opened, the other end of the pressing plate 41 can swing in a direction away from the wall plate 11 to loosen the fuel tank cap 20. In other embodiments, the pressing plate can also be pivoted to the wall plate 11 through a rotating shaft perpendicular to the wall plate 11, that is, the other end of the pressing plate can swing in the plane where the wall plate 11 is located, and when it swings to the outside of the fuel tank cap 20, the pressing plate is locked to the wall plate 11 through the padlock, thereby sealing the fuel tank cap 20.
