In addition, the second shell 202 also adopts an anti-crash design, which is composed of an inner layer, an anti-fall layer rubber-coated fabric and an anti-aging coating, wherein the inner layer rubber-coated fabric is an oil-proof layer, which is in direct contact with the working medium, can prevent the fuel from diffusing outward, and ensure the oil storage function, the anti-fall layer adopts high-strength nylon material to meet the requirements of fall suitability, and the anti-aging coating adopts hydrogenated nitrile as the main material, which has functions such as oil resistance and ozone resistance, and ensures that the use requirements are met during the service life. A bulletproof layer is also arranged at a part of the bottom of the second shell 202, and an oil-expanding layer and two layers of bulletproof reinforcement layer rubber-coated fabric are added on the basis of the anti-crash layer, wherein the oil-expanding layer is sandwiched between the two layers of bulletproof reinforcement layer rubber-coated fabric, and the bullet penetrates the box wall to form a bullet hole, and the oil-expanding material in the box wall is activated and expanded by the fuel to block the ballistic trajectory, and the bullet wound is rebounded by the high-strength, high-elasticity, tear-resistant bulletproof reinforcement layer material to prevent fuel leakage.

[0030] Please continue reading Figures 4 to 9 An oil control unit 3 is provided in the second shell 202, and the oil control unit 3 includes an oil delivery component 301, an oil transmission component 302, a monitoring component 303 and an adjusting component 304. The oil tank 2 also includes an end cover 203, and a part of the oil delivery component 301, the oil transmission component 302, the monitoring component 303 and the adjusting component 304 are respectively provided on the end cover 203, and the interior of the second shell 202 can also be inspected through the end cover 203.

[0031] Further, the oil delivery assembly 301 includes a first oil inlet end 3011, a second oil inlet end 3012 and a third oil inlet end 3013. Preferably, the first oil inlet end 3011 is pressure refueling, the second oil inlet end 3012 is gravity refueling, and the third oil inlet end 3013 is aerial refueling. The first oil inlet end 3011 and the second oil inlet end 3012 are both arranged in the first shell 201 and pass through the second shell 202, and the third oil inlet end 3013 is arranged in the end cover 203.

[0032] Furthermore, the oil delivery component 301 also includes a first pipeline 3014, a second pipeline 3015 and an oil outlet 3016, wherein the first oil inlet 3011 is connected to the oil outlet 3016 via the first pipeline 3014, the third oil inlet 3013 is connected to the first pipeline 3014 via the second pipeline 3015, and the second oil inlet 3012 is directly connected to the second shell 202 without the need for pipeline connection.

[0033] Furthermore, the oil delivery assembly 301 further includes a detection member 3017 and a third pipeline 3018. The detection member 3017 is disposed on the end cover 203 and faces the inside of the second housing 202, and the detection member 3017 is connected to the oil outlet 3016 via the third pipeline 3018. Preferably, the detection member 3017 and the third pipeline 3018 are designed to act on the first oil inlet 3011, i.e., pressure refueling, similar to the principle of the jump gun at a traditional vehicle gas station. A floating ball is disposed in the third pipeline 3018. As the amount of oil in the second housing 202 increases, the floating ball rises toward the detection member 3017. When a certain pressure is reached, the floating ball touches the detection member 3017, thereby disconnecting the refueling of the first oil inlet 3011.

[0034] Furthermore, the oil transmission assembly 302 includes at least one pump 3021. In the present embodiment, two pumps 3021 are provided. The pumps 3021 are provided at the bottom of the second housing 202. The oil transmission assembly 302 also includes an adapter 3022, an oil extraction pipe 3023 and a driver 3024. The adapter 3022 and the driver 3024 are both provided at the end cover 203. The oil extraction pipe 3023 is connected to one end of the adapter 3022. The oil transmission assembly 302 also includes a fourth pipeline 3025 and a fifth pipeline 3026. The pump 3021 is connected to one end of the adapter 3022 via the fourth pipeline 3025. The pump 3021 is also connected to the driver 3024 via the fifth pipeline 3026. In this example, the fourth pipeline 3025 is a pipeline for delivering oil, and the fifth pipeline 3026 is an electric pipeline, which drives the pump 3021 to pump oil through the action of the driving member 3024. Preferably, the connections of the above pipelines are all flexible connections, which further improves the safety inside the second housing 202.

[0035] Furthermore, the monitoring component 303 includes a feedback device 3031, an oil range tube 3032 and an alarm device 3033. The feedback device 3031 is arranged on the end cover 203. One end of the oil range tube 3032 is connected to the feedback device 3031 and is arranged in the second shell 202. The alarm device 3033 is arranged at one end of the oil range tube 3032 away from the end cover 203. The feedback device 3031 is further electrically connected to the control center, and the oil level height in the oil range tube 3032 is fed back in real time. The alarm device 3033 is used to give a timely alarm reminder when the oil level in the second shell 202 is too low, so as to avoid hidden dangers. The surface of the oil-line tube 3032 is also evenly distributed with first holes 30321 obliquely arranged relative to the end face of the oil-line tube 3032. Through the arrangement of the first holes 30321, when the second shell 202 falls accidentally, the oil-line tube 3032 can be directly broken along the first holes 30321 to reduce damage to the second shell 202.

[0036] Furthermore, the regulating assembly 304 includes a vent pipe 3041, a connector 3042 and a valve body 3043. The connector 3042 is disposed on the end cover 203. One end of each of the vent pipe 3041 and the valve body 3043 is connected to the connector 3042 and communicates with the second housing 202. The vent pipe 3041 is provided to balance the pressure inside and outside the fuel tank 2, and the valve body 3043 is a one-way vent valve. When the monitoring assembly 303 or the detection element 3017 fails, in order to prevent the waste of fuel caused by the siphon phenomenon of the vent pipe 3041, gas is introduced into the valve body 3043 to solve the problem of siphoning and avoid fuel waste.

[0037] Furthermore, the first shell 201 is arranged on the base 1, and positioning holes 101 are evenly arranged on the surface of the base 1. The system also includes a binding assembly 4, which acts on the first shell 201 to tighten the oil tank 2. The binding assembly 4 includes a pull ring 401, a strap 402 and an adjuster 403. The pull ring 401 is connected to the positioning hole 101, and the strap 402 is evenly distributed along the surface of the first shell 201. One end of the strap 402 is connected to the pull ring 401, and the other end is connected to another strap 402 through the adjuster 403. The adjuster 403 can achieve a loosening effect on the strap 402. A handle 5 is also arranged on the surface of the first shell 201, and the handle 5 is hidden on the surface of the first shell 201. Preferably, the handle 5 is designed to bear the weight of the oil tank 2.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
