The oil pipeline includes two oil pipes, the ends of which are connected by a connecting oil pipe. A set of self-sealing connector assemblies is installed along the length of each of the two oil pipes. Each set of self-sealing connector assemblies includes two or more self-sealing connector female ends arranged in sequence. The male end of the self-sealing connector at the bottom of the soft oil bladder of an oil tank is connected to the female end of the self-sealing connector on the pallet frame.

[0006] When in use, the soft oil sac is placed inside the lower shell: Before the soft oil bladder is filled with oil or when the oil in the soft oil bladder is used up, the top of the upper shell is placed inside the lower shell. When the soft oil bladder is full of oil, the top of the upper shell is located above and outside the lower shell, and the upper port of the lower shell and the upper port of the upper shell are detachably connected as one unit by a fastening assembly.

[0007] The soft oil bladder is equipped with an oil level indicator; the soft oil bladder has straps around its sides, and the lower shell has mounting holes that mate with the straps; lifting rings are provided on both sides of the lower shell; and reinforcing ribs are provided around the lower shell and on the top of the upper shell.

[0008] Both the upper port of the lower shell and the upper port of the upper shell have a ring of outwardly protruding flanges. The fastening assembly includes a clamping plate, bolts and nuts. One side of the clamping plate has a groove that mates with the flange. Both ends of the clamping plate have connecting plates with mounting holes for bolts and nuts. The flanges of the upper ports of the lower shell and the upper ports of the upper shell are clamped by a ring of clamping plates through the grooves. The ends of two adjacent clamping plates are fixed by bolts and nuts.

[0009] Both the upper port of the lower shell and the upper port of the upper shell have rectangular cross-sections. The flange of the upper port of the lower shell consists of four lower convex edges, and the flange of the upper port of the upper shell consists of four lower convex edges. During connection: after the upper port of the lower shell and the upper port of the upper shell are connected, the four upper and lower convex edges are respectively engaged by the slots of the clamping plates, and the ends of the two adjacent clamping plates are fixed by bolts and nuts.

[0010] The pallet frame is provided with oil tank installation positions corresponding to the female ends of the sealing joints. The mounting plate at the bottom of the lower shell of the oil tank is detachably connected to the oil tank installation position via a fixing mechanism.

[0011] This utility model's tray-mounted refueling device adopts a modular design. When the oil tank is fixed on the tray, the male and female connectors (i.e., self-sealing male and female ends) can be reconnected manually or by gravity. The male end connector, which connects to the oil inlet / outlet of the oil tank's flexible oil bladder, is equipped with a self-sealing connector to ensure that fuel does not spill from the flexible oil bladder. This connection method is simple. The advantages of this utility model are as follows: First, the outer shell structure design facilitates the placement and transportation of a large number of oil bladders; second, the internal soft oil tank uses a soft oil bladder, so the outer shell design does not need to consider strict sealing; third, the soft oil bladder automatically expands and contracts according to the amount of oil, and the opening design at 1 / 3 of the tank body can divide the entire oil tank into two parts. Before the oil tank is filled with oil, the upper part can be folded into the lower tank body, reducing the overall volume of the oil tank, saving space, and facilitating personnel handling; fourth, this design has a large opening area, which is conducive to personnel cleaning and maintenance. The soft oil bladder is only connected to the outer shell at the bottom. When the soft oil bladder is damaged and repaired, only the entire soft oil bladder needs to be replaced, which shows great flexibility in terms of transfer, storage, cleaning, and maintenance.

A self-sealing connector male 109 is designed on the bottom or lower side of the soft oil bladder 101. Straps 115 are designed around the sides of the soft oil bladder 101 to ensure a complete fit between the bladder and the metal outer shell, guaranteeing a secure fit. The straps 115 are also used for installing and removing the empty bladder and assist in emptying the soft oil bladder 101. To facilitate smooth filling and emptying of the oil bladder, an exhaust port is designed on the top of the soft oil bladder 101, equipped with an exhaust valve 106. This valve opens during filling and unloading and closes when the oil is full or empty. An oil level indicator is installed on the top of the soft oil bladder 101 to monitor the oil level inside. When the oil level drops to a certain height, the operator is alerted to replenish the oil.

[0015] Figure 6-8 In the design, the clamping plate 114 has a groove 1141 on one side that mates with the flange. The clamping plate 114 has connecting plates at both ends, with mounting holes 1142 on the connecting plates for bolts and nuts 111. A ring of clamping plates 114 is engaged with the flanges of the upper ports of the lower shell 102 and upper shell 103 via the groove 1141. The ends of adjacent clamping plates 114 are fixed with bolts and nuts 111. Both the upper ports of the lower shell 102 and upper shell 103 have rectangular cross-sections. The flange of the upper port of the lower shell 102 consists of four lower convex edges, and the flange of the upper port of the upper shell 103 also consists of four lower convex edges. During connection: after the upper ports of the lower shell 102 and upper shell 103 are aligned, the four upper and lower convex edges are engaged via the grooves 1141 of the clamping plate 114, and the ends of adjacent clamping plates 114 are fixed with bolts and nuts 111.
