[0023] According to an embodiment of the present invention, a modular fuel tank is provided, including a tank body 1 and a first protrusion 101, a second protrusion 103, a first recess 102, and a second recess 104 disposed on the tank body 1; the first protrusion 101 and the first recess 102 are respectively disposed on two opposite sides of the tank body 1 along a first direction X, and the second protrusion 103 and the second recess 104 are respectively disposed on two opposite sides of the tank body 1 along a second direction Y; two tank bodies 1 arranged adjacent to each other along the first direction X are connected, and the first protrusion 101 of one of them is limitedly connected to the first recess 102 of the other; two tank bodies 1 arranged adjacent to each other along the second direction Y are connected, and the second protrusion 103 of one of them is limitedly connected to the second recess 104 of the other; wherein, the first direction X and the second direction Y are perpendicular to each other.

[0024] In this embodiment, the modular fuel tank is provided with mutually cooperating protrusions and recesses in the first direction X and the second direction Y, respectively, so that multiple fuel tank units can be stably connected in two mutually perpendicular directions. This not only improves the layout flexibility to meet various usage needs, but also ensures the overall structural stability and safety through the mechanical interlocking of the protrusions and recesses. At the same time, it simplifies the installation process and ensures effective communication between fuel tank units, enabling free combination of capacity, rapid assembly and reliable operation, improving deployment convenience and effectively solving the problems of fixed fuel tank volume and cumbersome installation in existing fuel tanks.

[0025] In some embodiments, at least two of the first protrusion 101, the second protrusion 103, the first recess 102, and the second recess 104 are provided respectively; when two boxes 1 are arranged adjacent to each other along the first direction X, at least one pair of first protrusions 101 and first recesses 102 on the two boxes are connected; and / or, the boxes 1 are provided with a first interface 105 and a second interface 106 on opposite sides along the second direction Y; when two boxes 1 are arranged adjacent to each other along the second direction Y, the first interface 105 on one box and the second interface 106 on the other box are connected.

[0026] In this embodiment, three sets of the first protrusion 101 and the first recess 102 are provided, and two sets of the second protrusion 103 and the second recess 104 are provided. One set of the combination of the first protrusion 101 and the first recess 102 is connected, and the connected set is flush with the preset minimum liquid level of the oil tank.

[0027] Specifically, in this embodiment, three of each of the first protrusion 101 and the first recess 102 are provided, and they are distributed in an equilateral triangle.

[0028] In some embodiments, refer to Figure 1 and Figure 2The first protrusion 101 has a locking structure 2, which can be limited and connected with the first recess 102; and / or, the second protrusion 103 has a locking structure 2, which can be limited and connected with the second recess 104; the locking structure 2 includes a main body (not shown), a locking member 201 and a drive sleeve 202. The main body is mounted on the surface of the housing 1, the locking member 201 is disposed on the main body and can be engaged and connected with the recess of another modular oil tank; the drive sleeve 202 is axially movable and sleeved between the locking member 201 and the main body.

[0029] In this embodiment, the first protrusion 101 is provided with a locking structure 2, while the second protrusion 103 is not provided with a locking structure 2 and only adopts a direct connection structure.

[0030] In some embodiments, refer to Figure 1 and Figure 2 The locking member 201 has an open state and a closed state. The state of the locking member 201 is controlled by the axial position of the drive sleeve 202, wherein the drive sleeve 202 has a first position and a second position. When the drive sleeve 202 is in the first position, the driving locking member 201 is in the closed state, allowing the first protrusion 101 and the first recess 102 to separate and / or the second protrusion 103 and the second recess 104 to separate. When the drive sleeve 202 is in the second position, the driving locking member 201 is in the open state, limiting the connection between the second protrusion 103 and the second recess 104 and / or limiting the connection between the second protrusion 103 and the second recess 104.

[0031] Specifically, the locking member 201 is a claw-like locking structure with a tendency to expand outwards. The locking member 201 is controlled by the driving sleeve 202. In the first position, the driving sleeve 202 constrains the locking member 201, reducing the outward expansion amplitude of the locking member 201 to less than the radial length of the first recess 102 and the second recess 104, so as to separate the two. In the second position, the driving sleeve 202 no longer constrains the locking member 201, increasing the outward expansion amplitude of the locking member 201 to greater than the radial length of the first recess 102 and the second recess 104, so as to limit the connection between the two.

[0032] In some embodiments, refer to Figure 2 The locking member 201 is provided with a snap-fit ​​portion 203 that radiates radially along the main body. The first recess 102 is provided with a groove (not shown). When the locking member 201 is in the open state, the snap-fit ​​portion 203 opens and snaps into the groove. The first recess 102 is also provided with a magnetic attraction structure 6, which can be magnetically connected to the locking member 201, and / or the second recess 104 is also provided with a magnetic attraction structure 6, which can be magnetically connected to the second protrusion 103.

The snap-fit ​​portion 203 is a plate-like structure that protrudes radially and can snap into the groove corresponding to the recessed portion, making the locking more secure and reducing the risk of falling off.

[0034] Specifically, when hoisting or pushing the oil tank, there is no need to precisely align the first protrusion 101 or the second protrusion 103. It can automatically slide into the bottom mating position along the inner wall of the first recess 102 or the inner wall of the second recess 104, reducing the difficulty of manual alignment.

The connecting component passes through the first protrusion 101 and the first recess 102, and the sealing component is provided between the connecting component and the first recess 102.

[0036] Specifically, the sealing component is a sealing rubber ring, and the connecting components are a snap-fit ​​flange and a delivery pipe.

[0037] In some embodiments, the communication component includes a one-way valve (not shown) for controlling the direction of oil flow.

[0038] In some embodiments, refer to Figures 1 to 4 The second protrusion 103 and the second recess 104 are not connected and abut against each other. The second protrusion 103 extends beyond the second recess 104 and is longer than the length of the connecting component.

[0039] In this embodiment, the combination of the second protrusion 103 and the second recess 104 not being connected is a wedge-shaped prism structure.

[0040] In some embodiments, refer to Figure 3 and Figure 4 The housing 1 is also equipped with an intelligent monitoring module 5, which is located inside the cavity of the housing 1. The intelligent monitoring module 5 integrates at least one of the following: oil level sensor, temperature sensor, oil stain detection module, and oil leak detection electrode.

[0041] Specifically, the intelligent monitoring module 5 has a magnet inside, which can be magnetically attached to the cavity of the box 1.

[0042] Specifically, the intelligent monitoring module 5 is equipped with LED alarm lights and a buzzer for feedback, and the data is transmitted to the unit control panel via Bluetooth.

[0043] Furthermore, the intelligent monitoring module 5 is located inside the housing 1, on the same side as the second recess 104.

[0044] In some embodiments, refer to Figure 1 and Figure 4 The housing 1 is also provided with a moving module 3, which is located on the surface of the housing 1 on the same side as the second recess 104, and at least four sets are provided. The moving module 3 includes a storage slot 302 and a retractable universal wheel 301. The retractable universal wheel 301 is installed inside the storage slot 302 and can extend and retract along the axial direction of the first oil outlet. The housing 1 is also provided with a folding handle 4, which can extend and retract along the second direction Y.

[0045] Optionally, the retractable caster wheel 301 may include, but is not limited to, a linearly adjustable mechanism such as a cylinder or hydraulic cylinder.

[0046] Specifically, in this embodiment, the retractable caster wheel 301 is a cylinder structure, and its extension and retraction can be adjusted by pressing a foot pedal or a button.
