Description

Technical Field

[0001] This utility model belongs to the field of oil storage and transportation technology, and specifically relates to an oil storage device. Background Technology

[0002] Chinese Patent (Announcement No. CN 221189779 U, Announcement Date 2024.06.21) discloses a soft oil bladder, a container for adding oil or fuel in the field or during a trip. It is characterized by being lightweight, foldable, wear-resistant, drop-resistant, highly adaptable to the environment, easy to carry, and simple to use.

[0003] During transport, if the soft oil bladder is damaged in extremely harsh outdoor environments, the fuel supply during the expedition cannot be guaranteed, thus affecting the long-distance progress. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and to provide a fast-moving oil storage device for expeditions, which can flexibly and mobilely provide oil support during expeditions.

[0005] The technical solution of this utility model is: An expedition-ready, rapidly mobile oil storage device includes an oil tank comprising a flexible oil bladder and an outer shell surrounding the flexible oil bladder. The outer shell consists of a lower shell and an upper shell. The bottom of the lower shell has two forklift holes, and a passage for easy manual operation is provided between the two forklift holes at the bottom of the lower shell. The top of the flexible oil bladder is equipped with an oil inlet / outlet, an exhaust valve, and a lifting strap. The self-sealing connector and drain outlet at the bottom of the flexible oil bladder pass through the bottom of the lower shell and are positioned at the passage.

[0006] When in use, the soft oil bladder is placed inside the lower shell. When the soft oil bladder is not 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 outside and above the lower shell. 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.

[0008] The soft oil bladder is designed with straps around its sides, and the lower shell has assembly holes that mate with the straps.

[0009] 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.

[0010] 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.

[0011] The height of the upper shell is 1 / 3 of the height of the tank.

[0012] Lifting rings are provided on both sides of the lower shell.

[0013] The lower shell has reinforcing ribs around its perimeter and the top of its upper shell.

[0014] 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.

Detailed Implementation

[0016] Figure 1-5The portable oil storage device is an oil tank, consisting of an outer shell and an inner flexible oil bladder 101. The bottom of the flexible oil bladder 101 protrudes from the outer shell via a connector and connects to the outside via a valve and quick connector. Two forklift holes 105 are provided at the bottom of the oil tank for easy forklift handling. 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. A passage for manual operation is provided between the two forklift holes 105 at the bottom of the lower shell 102. The flexible oil bladder 101 automatically expands and contracts according to the amount of oil. The tank has a 1 / 3 opening design, dividing the entire oil tank into two parts (lower shell 102 and upper shell 103). Before filling, the upper shell 103 can be folded into the lower shell 102, reducing the overall volume of the oil tank, saving space, and facilitating 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.

[0017] A CRJ-type male oil inlet (i.e., oil inlet / outlet 112) is installed on the top of the soft oil bladder 101 for adding oil. A self-sealing connector 109 is designed at 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 at the top of the soft oil bladder 101, equipped with an exhaust valve 106. This valve opens when adding or unloading oil 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 indicator prompts the operator to replenish the oil.

[0018] 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.
