[0002] Aircraft consume a large amount of fuel during flight, and to ensure normal operation, large quantities of aviation fuel are stored near airports. Refueling is done through pipelines, but the rapid flow of aviation fuel within these pipelines can cause it to heat up due to friction. Given its low flash point, excessively high fuel temperatures pose a significant safety hazard. Currently, these pipelines lack sufficient safety measures, and the only solution is to shut down valves and isolate the pipelines in case of safety issues. Utility Model Content

[0005] Preferably, the upper end of the reinforcing frame extends to the outer wall of the mounting ring, the mesh of the dividing mesh is a square structure, and the side end of the dividing mesh is fixedly connected to the outer wall of the reinforcing frame.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: A reinforcing frame and cooling plate are installed inside the pipeline. When aviation fuel passes through the cooling plate, the cooling water flowing in the circulation channel can cool the aviation fuel, preventing it from reaching its flash point and ensuring the safety of the aviation fuel during pipeline transport. The dividing mesh assists in cooling and heat dissipation, while preventing the aviation fuel from flowing too slowly within the pipeline, ensuring the aircraft refueling speed. When flames occur on the inner wall of the pipeline, the dividing mesh and installation ring can divide the flames, removing sufficient energy or activated energy molecules from the combustion zone, thus slowing down the reaction rate or preventing the reaction from becoming self-sustaining. During combustion, quenching causes excessive heat loss due to heat conduction when the flame contacts the side wall of the combustion space, leading to combustion instability and ultimately extinguishing the flame, achieving the quenching phenomenon. Furthermore, when flames appear inside the pipeline, the heat-sensitive glass column will be damaged, allowing cooling water to flow into the pipeline body, thereby cooling and extinguishing the fire inside the pipeline body and ensuring safety.

Detailed Implementation
[0015] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0016] Please see Figure 1-3 This utility model provides a technical solution: an explosion-proof reinforced structure for pipelines used in chemical safety production, including a pipeline body 1. The inner wall of the pipeline body 1 has a stepped structure. An installation ring 2 is inserted into the middle of the pipeline body 1. A reinforcing frame 4 is fixedly connected to the middle of the installation ring 2. The reinforcing frame 4 has a U-shaped structure. A cooling plate 5 is inserted into the middle of the reinforcing frame 4. A dividing mesh 3 is fixedly connected to the inner wall of the installation ring 2. Multiple cooling rings 10 are embedded in the middle of the cooling plate 5. Both ends of the cooling rings 10 penetrate the cooling plate 5. Cooling heads 11 are fixedly connected to the inner wall of the cooling rings 10. Multiple communicating cavities 17 are provided in the middle of the cooling plate 5. Insertion grooves 18 are provided on both sides of the inner wall of the communicating cavities 17. Sealing blocks 13 are inserted into the insertion grooves 18. A thermosensitive glass column 16 is provided at the upper end of the sealing block 13. The lower end of the sealing block 13 is provided with a sealing head 15, and the lower end face of the sealing block 13 is provided with a sealing concave surface 14. The upper end of the pipe body 1 is provided with a water pipe 8. The middle of the cooling plate 5 is provided with a circulation channel 9. The upper end of the cooling plate 5 is fixedly connected to a limiting plate 7. The upper end of the reinforcing frame 4 extends to the outer wall of the mounting ring 2. The mesh of the dividing mesh 3 is a U-shaped structure. The side end of the dividing mesh 3 is fixedly connected to the outer wall of the reinforcing frame 4. The dividing mesh and the cooling ring 10 can divide the aviation fuel flowing in the pipe body 1, and can transfer and dissipate the heat accumulated in the aviation fuel. The aviation fuel is cooled by the cooling water circulating in the circulation channel. The dividing structure increases the heat dissipation efficiency, avoids heat accumulation leading to high aviation fuel temperature, and can also form a quenching phenomenon, which can extinguish the flame in the event of a fire.
[0017] The limiting plate 7 has an arc-shaped structure, and the diameter of the limiting plate 7 is the same as the diameter of the mounting ring 2. The lower end of the cooling plate 5 is fixedly connected to the fixing post 6, which is inserted into the inner wall of the reinforcing frame 4. The circulation channel 9 has a U-shaped structure, and the cooling ring 10 is located in the middle of the circulation channel 9. The outer wall of the cooling ring 10 is located at the circulation channel 9. The reinforcing frame 4 reinforces the dividing mesh 3. After the cooling plate 5 is inserted into the middle of the reinforcing frame 4, the limiting plate 7 is snapped onto the outer wall of the mounting ring 2. Then, the mounting ring 2 is installed into the pipe body 1, and the reinforcing frame 4 is reinforced by the cooling plate 5.
[0018] The connecting cavity 17 and the cooling ring 10 correspond one-to-one. The lower end of the connecting cavity 17 passes through the cooling head 11. Both sides of the connecting cavity 17 are provided with connecting grooves 12, which are connected to the circulation channel 9. The sealing block 13 has a cross-shaped structure, and the sealing concave surface 14 has a funnel-shaped structure. The upper end of the sealing head 15 is engaged in the middle of the sealing concave surface 14. The middle of the sealing block 13 is provided with a connecting hole. The upper end of the sealing head 15 is connected to the thermal glass column 16. When a fire occurs inside the pipe body 1, the thermal glass column 16 will break due to high temperature, thereby causing the sealing head 15 to lose its fixation, connecting the connecting cavity 17 with the cooling head 11, so that cooling water is sprayed out from the cooling head, thereby cooling and extinguishing the fire inside the pipe body 1, ensuring safety.
