[0026] This utility model relates to a pallet-based modular refueling device, which has both storage and refueling functions. Based on a modular design, the pallet-based modular refueling device uses a specially designed pallet as its base and incorporates installed oil storage and refueling modules. It is a modular containerized refueling equipment with centralized oil storage and refueling capabilities, as well as the ability to distribute refueling to various points. It can supply fuel to ground vehicles using military diesel fuel and other diesel-powered power generation and equipment. It can be loaded, unloaded, transported, and deployed on the battlefield using off-road self-loading trucks.

[0027] The pallet-mounted modular refueling unit adopts a modular design. A complete pallet-mounted modular refueling unit has two modes: one consists of 10 oil storage tanks, each storing a certain amount of oil, with a maximum storage capacity of 1000m³. 3 One type consists of eight oil storage tanks and a pump unit, used for pumping and storing oil for the system. The palletized modular refueling unit is a lightweight, modular, air-transportable refueling system that can be carried by helicopter or transported by off-road vehicle.

[0028] 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.

[0047] This utility model's pallet-based refueling device consists of one oil storage module, one refueling module 300, and one pallet 200. The pallet 200 serves as the base, with the oil storage module and refueling module 300 mounted on it. The pallet 200 connects the oil passages of the oil storage module to the pipelines of the refueling module, forming a closed passage. In terms of operational functionality, the pallet-based refueling device should facilitate loading, unloading, transportation, and refueling. It should be well-matched with receiving equipment and refueling tools, meeting the different refueling speeds of various receiving equipment. The oil tanks should be easy to empty and clean, and the device should have good overall wear resistance and puncture resistance. Regarding refueling: the oil tanks on the pallet of a single pallet-based refueling device can be connected or disconnected to achieve interconnected oil delivery; individual oil tanks can be easily disassembled and transported independently, allowing forklifting and hoisting, making self-refueling quick and convenient for soldiers; multiple pallets can be combined for interconnected refueling. The refueling module can be detached and placed on the ground to connect with other pallets containing oil storage tanks to perform the refueling function. Transportation: When the palletized refueling unit is fully loaded, it can be loaded, unloaded, transported, and deployed on the battlefield using heavy-duty off-road self-loading trucks, facilitating securing, lifting, and forklifting. For individual tank transport, it can be loaded onto light-duty or larger trucks, or transported by helicopter from outside the cabin. Service Use: When the tanks are full, they can be transported by vehicle or ship to sea. After the tanks are emptied, they are easy to stack and transport, and easy to clean.

[0048] Oil storage module: Can be composed of 10 individual oil tanks. Each oil tank can be quickly and dry-installed and detached from a special pallet. The oil tanks installed on the special pallet are interconnected by oil circuits, forming a whole oil storage unit. The tank body is coated with an automatic sealing material, which can quickly expand and plug the damage point when the tank body is damaged. While ensuring strength and rigidity, the weight of the oil tank is reduced, and a single oil tank can be forklifted and lifted.

[0049] The refueling module 300 includes an oil pump unit 301, a standby refueling pump (i.e., a mobile electric pump refueling unit 303), a pump power source, a piping system, valves, a refueling spring reel, a filter separator 308, a self-sealing refueling nozzle (referred to as a refueling nozzle) 307, a control system, an electrostatic grounding device, a portable dry powder fire extinguisher, a frame, and other components. It has functions such as refueling, oil suction, and oil recirculation. The refueling module 300's external dimensions are comparable to the two oil tanks in the oil storage module 100, occupying the horizontal space of two oil tanks. It is connected and fixed to the tray 200 using vibration-damping and noise-reducing methods, with rubber pads added at the connection points for noise reduction. The filter separator 308 is a reserved accessory for future expansion, used to separate impurities and water from fuel during aerial refueling.

[0050] Pallet 200: Measuring no larger than a standard pallet, it serves as the base for securing oil storage modules, refueling modules, and pipeline accessories. It features mechanisms for fixing oil tanks and refueling modules. The pallet contains internal oil pipelines and valves connecting to various oil tanks, enabling rapid loading and unloading. Dry-type quick-connect couplings are used between the pipelines on the pallet and the oil tanks for quick connection and disconnection. The main pipeline inlet and outlet positions on the pallet are rationally designed for convenient use with two or more pallets. The pallet's overall weight is reduced while maintaining strength and rigidity. The pallet is equipped with forklift slots, lifting rings, and cast steel corner brackets for securing standard pallets, allowing for loading, unloading, and transportation using self-loading trucks.

[0051] Depending on different service requirements, a single pallet-mounted refueling unit can be configured in three different ways to perform different functions.

[0052] Format 1: Pallet + 10 oil tanks, used for oil storage and transportation, with individual tanks distributed for self-service refueling.

[0053] Format 2: Refueling module + 8 oil tanks, functioning as transportation and vehicle refueling, with individual tanks distributed for self-service refueling at scattered locations.

[0054] Format 3: Refueling module (with filter, occupying 1 tank slot) + 7 tanks, used for transportation, as well as refueling vehicles and helicopters, with scattered distribution of single tanks for self-service refueling.

[0055] In addition, multiple pallet-type refueling devices can be used in combination to increase the fuel supply.

[0056] Figure 1-5In this oil tank 100, the exterior is an outer shell, and the interior is a flexible oil bladder 101. The bottom of the flexible oil bladder 101 protrudes from the outer shell through a connector and connects to the outside via a valve and a quick connector. Two forklift holes 105 are provided at the bottom of the oil tank for easy forklift handling. The main body of the outer shell is made of aluminum alloy, and the internal flexible oil bladder 101 has a volume of 1000L and its shape conforms to the outer shell. The outer shell consists of a lower shell 102 and an upper shell 103. Between the two forklift holes 105 at the bottom of the lower shell 102, there is a passage for manual operation. The flexible oil bladder 101 automatically expands and contracts according to the amount of oil. The tank has a 1 / 3 opening design, which divides the entire oil tank into two parts (i.e., the lower shell 102 and the upper shell 103). Before filling the tank, the upper shell 103 can be folded into the lower shell 102, reducing the overall volume of the oil tank, saving space, and facilitating personnel handling. When the soft oil bladder 101 is full of oil, the top of the upper shell 103 is located outside and above the lower shell 102. The upper port of the lower shell 102 and the upper port of the upper shell 103 are detachably connected as one unit via a fastening assembly. The bottom of the lower shell 102 of the oil tank has a mounting plate 107 that cooperates with the fixing mechanism.

[0057] A CRJ-type inlet male (i.e., inlet / outlet 112) is installed on the top of the soft oil bladder 101 for adding oil. 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.

[0058] 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.

[0059] Figure 9-11 In the pallet 200, a pallet frame is provided, on which an oil pipeline is installed. The oil pipeline includes two oil pipes 201, the ends of which are connected by a connecting pipe. A set of self-sealing connector assemblies is installed along the length of each of the two oil pipes 201. Each set of self-sealing connector assemblies includes two or more self-sealing connector female ends 205 arranged sequentially. The self-sealing connector male end 109 at the bottom of the flexible oil bladder 101 of an oil tank 100 is connected to the self-sealing connector female end 205 on the pallet frame. Oil tank mounting positions are provided on the pallet frame corresponding to the respective self-sealing connector female ends 205. The mounting plate 107 at the bottom of the lower shell 102 of the oil tank 1 is detachably connected to the oil tank mounting position via a fixing mechanism. An operating hole 204 is provided on the side of the pallet frame. The self-sealing connector female end 205 is connected to the oil pipe 201 via a bend 206, and a switch valve 202 is installed on the bend.

[0060] Figure 12-16 In the refueling module frame 305, a working oil channel group 306 is integrated to form a refueling module 300. The working oil channel group includes a first working oil channel 3011 and a second working oil channel 3012 connected in parallel with the first working oil channel 3011.
