Description

Technical Field

[0001] This utility model relates to the field of bulletproof fuel tank technology, and in particular to a combined bulletproof fuel tank. Background Technology

[0002] Oil tankers transport flammable and explosive petroleum products. During combat, counter-terrorism, and peacekeeping missions, these tankers are highly vulnerable to enemy attacks. An attack could trigger a severe explosion and fire, posing a deadly threat to nearby personnel and equipment. Therefore, it is essential to equip oil tankers with reliable bulletproof capabilities to enhance their survivability.

[0003] Existing protective refueling trucks mostly use armor plates or ceramic composite armor plates as external armor structures for tank protection. This type of armor plating not only significantly increases the overall vehicle size, but the welded structure of the armor plates is also prone to insufficient weld strength, leading to a decrease in ballistic protection performance. In addition, ceramic composite armor plates have high material and processing costs, posing an economic challenge in practical applications. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing armor plating not only significantly increases the overall size and weight of the vehicle, but also that the welded structure of the armor plating is prone to reduced ballistic performance due to insufficient weld strength. Therefore, a combined bulletproof fuel tank is proposed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 A combined bulletproof fuel tank includes a fuel tank assembly 1, side protection assemblies 2 on both sides of the fuel tank assembly 1, a lower protection assembly 3 at the bottom of the fuel tank assembly 1, a tail protection assembly 4 at the rear of the fuel tank assembly 1, an operating compartment and a chassis driver's cab at the front of the fuel tank assembly 1, and a front partial protection 5 between the fuel tank assembly 1 and the operating compartment; Reference Figures 1-4The oil tank assembly 1 consists of an oil tank 101, longitudinal beam pads 102, longitudinal beams 103, longitudinal beam reinforcing ribs 104, and a tank top pad 105. The oil tank 101 is welded from stainless steel plates. Two longitudinal beam pads 102 are installed at the bottom of the oil tank 101 and are welded to the oil tank 101. The longitudinal beams 103 are welded to the longitudinal beam pads 102. The longitudinal beam reinforcing ribs 104 are welded to the inner side of the longitudinal beams 103. Three sections of tank top pads 105 are welded to the front, middle, and rear of the oil tank 101. The tank top pads 105 are used for welding and installing brackets. The longitudinal beam pads 102, tank top pads 105, and oil tank 101 are all welded intermittently to avoid stress concentration caused by direct welding of the main load-bearing components to the oil tank 101. This also reduces the welding deformation of the oil tank 101 and ensures that the overall structure of the oil tank assembly 1 is solid and reliable, meeting the requirements for off-road driving. Reference Figures 1-4 The side protection assembly 2 includes a side protection plate 201, a first bracket 202, a first pad 203, a second bracket 204, a second pad 205, a third bracket 206, and a third pad 207. The side protection plate 201 is made of bulletproof steel plate and is formed by cold forming process, with multiple small-angle bending steps to form an integral shape. After bending, it forms a 150° structural inclination angle, which reduces the impact force when a bullet hits the side protection assembly 2, thus providing protection for both sides of the oil tank body, and the overall shape is aesthetically pleasing. The first bracket 202 is provided in 3 sets. The first bracket 202 is welded to the first pad 203 and the top pad 105 of the tank. The three sets of the second bracket 204 are arranged in sequence. Inside the side protective plate 201, bracket 204 is welded to pad 205, and bracket 204 is welded to tank top pad 105; a set of bracket 3 206 is installed at the rear of the inside of the side protective plate 201, and bracket 3 206 is welded to pad 3 207, and bracket 3 206 is welded to tank top pad 105; pad 1 203, pad 2 205, and pad 3 207 are all bulletproof steel plates, and the inside of the side protective plate 201 is connected to pad 1 203, pad 2 205, and pad 3 207 respectively using a multi-point internal plug welding process; bracket 1 202, bracket 204, and bracket 3 206 are all made of ordinary steel plates bent and formed and have weight-reducing holes, which reduces the structural weight while ensuring strength; Reference Figures 1-5 The lower protective assembly 3 consists of a lower protective plate 301 and a lower protective bracket 302. The lower protective plate 301 is made of bulletproof steel plate and is formed by cold forming process, bending at small angles in multiple steps to form an integral shape. After bending, it forms a 150° structural inclination angle. The lower protective bracket 302 is welded to the tank top pad 105. The lower protective plate 301, the lower protective bracket 302, and the bracket 204 are fixed with bolts, making disassembly and assembly convenient. Reference Figures 1-3The tail protection assembly 4 includes a tail protection plate 401 and a tail bracket 402. The tail protection plate 401 is made of bulletproof steel plate and is formed by cold forming process, step-by-step bending at small angles to form an integral shape. After bending, it forms a 160° structural tilt angle. The tail bracket 402 is welded to the rear end of the oil tank. The tail protection plate 401 and the tail bracket 402 are fixed by bolts. Reference Figures 2-4 The front partial protection 5 consists of a front protective plate 501 and a connecting plate 502. Both the front protective plate 501 and the connecting plate 502 are bulletproof steel plates. The front protective plate 501 is formed by cold working process, and is formed by bending at small angles in multiple steps. After bending, it forms a 150° structural tilt angle, which reduces the impact force when the bullet hits the side protection assembly 2. The front partial protection 5 provides local protection for the gap between the oil tank assembly 1 and the control room. The front of the oil tank assembly 1 consists of the control room and the chassis cab in sequence. The chassis cab itself has protective performance, thus ensuring the protection capability of the front of the oil tank assembly 1.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
