Abstract
Description
Technical Field
[0001] The invention relates to the technical field of explosion-proof oil tanks, and in particular to a destruction-resistant, bullet-proof, explosion-suppressing oil tank structure and an explosion-proof installation method. Background Art
[0002] A fuel tank is a container for oil, specifically a device for storing fuel oil on a machine driven by a diesel or gasoline engine. Conventionally, the space above the liquid level of a fuel tank is filled with a flammable mixed gas. When there is a fire source, the fire source will ignite the adjacent mixed gas. If the combustion of the mixed gas is not restricted, it will spread rapidly. Due to ignition and flame propagation, an increasing pressure wave will be generated in front of the flame front. The pressure wave strongly compresses the unburned mixed gas, which will cause the fuel tank to explode. The whole process takes only a few milliseconds.
[0003] Therefore, in the process of production, transportation, storage and use, combustion and explosion accidents are often caused by improper safety measures or accidents, which often cause significant property losses and casualties. Therefore, suppressing the fire and explosion of dangerous chemicals has attracted more and more attention.
[0004] In recent years, the emergence of various explosion-proof materials has effectively solved the safety issues of flammable and explosive liquids (gases) during production, storage and transportation, among which alloy mesh explosion-proof materials are particularly widely used.
[0005] For example, patent CN217892506U discloses a destruction-resistant, bulletproof, explosion-suppressing fuel tank structure assembly. In this patent, in order to prevent the fuel tank from being hit by stray bullets or bullets and causing an explosion, explosion-suppressing materials are filled inside the fuel tank. Although the explosion-suppressing effect can be achieved, the contact surface area is small, the internal space utilization rate of the fuel tank is low, and the weight is large, which affects the oil pumping speed.
[0006] To this end, we provide a destruction-resistant, bullet-proof, and explosion-suppressing fuel tank structure and an explosion-proof installation method to solve the above problems. Summary of the invention

[0058] Compared with the prior art, the present invention has the following beneficial effects:
[0059] The present invention improves the ability of the fuel tank to resist surge impact by using a structure and explosion-suppressing materials filled through a partition at the bottom of the fuel tank. In the past, the fuel utilization rate of the fuel tank was 95%, and after filling with explosion-suppressing materials, the fuel utilization rate was about 90%. By setting a partition, the amount of explosion-suppressing materials is reduced, the space occupancy rate is reduced, the fuel utilization rate is improved, the oil pumping speed is improved, the weight of the fuel tank can be reduced, the vehicle endurance is increased, and the cost is reduced. The present invention realizes the protection of the outer ring base layer by setting a larger multi-faceted hollow explosion-proof ball on the outside, which can ensure the basic explosion-suppressing effect, and realizes the main explosion-suppressing effect by the small-diameter explosion-proof ball on the inside, so that when the temperature rises, the space for steam expansion is limited and the pressure will not rise sharply. The small-diameter explosion-proof ball is limited to expand excessively by the external multi-faceted hollow explosion-proof ball, and the explosion-proof ball can prevent the combustion from developing from low-speed deflagration to high-speed detonation by weakening the shock wave strength.
[0060] The present invention arranges the distribution on the multi-faceted hollow explosion-proof balls to be a hexagonal honeycomb distribution, and the honeycomb structure can absorb and disperse the impact energy through its porosity. When subjected to external force impact, the holes in the honeycomb structure will deform, thereby absorbing energy and reducing the damage to the subsequent structure caused by the impact. The present invention connects a plurality of multi-faceted hollow explosion-proof balls through vertical ropes and horizontal ropes. When the flexible shaft is filled or released with gasoline, the lifting and lowering distribution of the multi-layer multi-faceted hollow explosion-proof balls is achieved through buoyancy, and the contraction and extrusion effect is achieved through the telescopic rubber cover, forcing the multi-faceted hollow explosion-proof balls in the telescopic rubber cover to squeeze the oil tank body under the protective partition, thereby achieving an anti-destruction, bulletproof and explosion suppression effect.
