Description

Technical Field

[0001] The present invention relates to a backpack rapid fire extinguishing system, in particular to a fire extinguishing system based on a C4 twin-type fluorosurfactant, which is mainly used as a highly efficient fire extinguishing device for rapidly extinguishing solid fires in the early stages of fires. Background Art

[0002] With the acceleration of urbanization and the rapid development of industrialization, the frequency and harmfulness of fires are increasing, especially in some high-risk places, such as chemical warehouses, oil depots, forests, etc., where fire fighting is more difficult. Rapid extinguishing of initial fires is crucial to reduce the spread of fires, avoid property losses and protect personnel safety. Backpack rapid fire extinguishing systems have become important equipment in the firefighting field because of their easy portability and rapid response. This type of equipment is suitable for initial fire fighting, especially in places that are difficult for personnel to reach, and can provide flexible and rapid fire fighting support.

[0003] However, with the continuous development of fire extinguishing agents, traditional water-based fire extinguishing agents or foam fire extinguishing agents can no longer meet the needs of modern fire fighting. Fluorosurfactants, especially C4 twin-type fluorosurfactants, have gradually become an important choice in the field of fire fighting due to their excellent fire extinguishing performance and strong high temperature resistance. This type of fire extinguishing agent can quickly suppress flames, reduce the temperature of the fire source, and show good fire extinguishing effects in complex environments such as high temperature and oil fires. However, the special molecular structure of fluorosurfactants also makes them face many challenges during storage, transportation and use.

[0004] Due to the complex molecular structure and unique chemical properties of fluorosurfactants, they are prone to leakage, stratification or precipitation during storage and transportation, which directly affects the fire extinguishing effect and may cause waste or failure of the fire extinguishing agent. Existing backpack fire extinguishing systems are often designed based on water-based fire extinguishing agents or traditional foam fire extinguishing agents, and fail to take into account the particularity of fluorosurfactants. Traditional storage equipment cannot meet the requirements of fluorosurfactants in terms of sealing and safety, so fire extinguishing agents are prone to leakage or contamination during use, affecting fire extinguishing efficiency.

[0005] The fluidity and viscosity of fluorosurfactants are different from those of traditional water-based fire extinguishing agents, which requires the spray system to provide higher pressure and stable spraying effect. However, the existing backpack spray systems are mostly based on the characteristics of water or foam fire extinguishing agents, and their spray system design is difficult to adapt to the spraying needs of fluorosurfactants. Specifically, there are problems such as uneven spraying of fire extinguishing agents, pressure fluctuations, and nozzle blockage, which will affect the efficiency of fire extinguishing, especially in the early stages of a fire, when it is crucial to quickly extinguish the fire source.

[0006] Traditional fire-fighting equipment has limitations in terms of the efficiency of using fire-extinguishing agents and the ease of operation. The fire-extinguishing agent storage tanks of traditional equipment generally adopt a fixed design, and the replacement process is cumbersome, which limits the rapid replenishment and replacement of fire-extinguishing agents. Especially in high-intensity and high-frequency fire-fighting tasks, the continuous working ability of the equipment is difficult to guarantee. Modern fire-fighting tasks require equipment to have higher modularity and flexibility to cope with fire-fighting needs in different scenarios.

[0007] As an innovative solution to the above problems, the backpack rapid fire extinguishing system based on C4 twin fluorosurfactants is mainly designed to improve fire extinguishing efficiency and flexibility. This type of system allows a single operator to carry it on their back, so that they can quickly move to the fire source to quickly extinguish the initial fire. Summary of the invention

[0008] In order to overcome the shortcomings of the prior art, the present invention provides a backpack rapid fire extinguishing system based on C4 twin-type fluorosurfactant, which aims to greatly improve the fire extinguishing efficiency through advanced storage box design and intelligent control technology, and ensure rapid deployment and efficient operation in emergency fire situations.

[0009] The embodiment of the backpack rapid fire extinguishing system realizes an efficient and intelligent fire extinguishing function through the organic combination of the backpack structure, the liquid supply system, the power supply system and the intelligent sensor system.

[0011] The backpack rapid fire extinguishing system based on C4 twin fluorosurfactant of the present invention has a reasonable design of the backpack structure, and the operator can quickly carry and operate the system to quickly extinguish the fire. The fire extinguishing agent based on C4 twin fluorosurfactant improves the fire extinguishing efficiency and greatly reduces the probability of re-ignition. The system has a flexible quick-connect design, which can quickly replace the fire extinguishing agent storage box during the fire extinguishing process to ensure continuous liquid supply and enhance the fire extinguishing time. The power supply system is electrically connected to the intelligent sensing system, and components such as liquid level sensors and temperature sensors perform real-time detection of the environment within the detection range. The acquired signals are analyzed by the evaluation unit, and the results are displayed on the LCD screen, and an alarm is triggered. The posture detection module determines whether the human body has not moved for a long time. Once it is determined to be abnormal, the alarm system is immediately triggered, and the location information is sent to the Internet of Things platform to ensure that the rear personnel can quickly obtain the location information and provide support.

[0012] Through the organic combination of the above technical solutions, storage and transportation of fire extinguishing agents are guaranteed. The efficient and intelligent fire extinguishing function of the backpack rapid fire extinguishing system in complex environments ensures that users can respond to fires quickly and continue operations, greatly improving fire extinguishing efficiency and safety.

The specific embodiment includes a backpack structure, a liquid supply system, a power supply system and an intelligent sensor system.

[0029] In this embodiment, the backpack structure is a double-layer structure, which is divided into an outer layer packaging and an inner layer frame. The outer layer is composed of an outer shell 10, a backpack top cover 8, and a bottom cover 13, and the backpack top cover 8 and the bottom cover 13 are adhered to the outer shell 10 by an adjustable adhesive tape 6.

[0036] Preferably, the special coating is a polyurethane or fluororesin coating resistant to corrosion by fluorine compounds to ensure that the C4 gemini-type fluorosurfactant does not chemically react with the storage box material during storage.

[0037] Preferably, the liquid outlet of the fire extinguishing agent storage tank 9 is provided with a check valve, which is used to prevent the fire extinguishing agent from flowing back into the storage tank when not in operation, thereby avoiding leakage or waste of the fire extinguishing agent. The check valve adopts an automatic opening and closing mechanism, so that when the liquid supply system is in operation, the fire extinguishing agent can flow out smoothly; when the liquid supply system stops working, the check valve automatically closes to ensure that the fire extinguishing agent will not flow back into the storage tank due to gravity or other factors. The design of the check valve improves the safety and reliability of the system, prevents the ineffective flow of the fire extinguishing agent, and reduces the risk of contamination.

[0038] Preferably, the inlet of the fire extinguishing storage box 9 is matched with the fire extinguishing storage box cover 17 to ensure the effective sealing and safe storage of the fire extinguishing agent inside the box, and to facilitate rapid opening to replenish the fire extinguishing agent when needed. The box cover 17 prevents foreign matter from entering the box through a tightly matched structural design, ensuring the sealing of the fire extinguishing storage box and the stability of the fire extinguishing agent.

The pump is made of high-efficiency motors and corrosion-resistant materials to ensure that it can maintain excellent performance under long-term and high-load operation to meet the needs of the fire extinguishing system. Compared with traditional mechanical pumps, DC electric diaphragm pumps can provide higher flow and pressure at lower power consumption, which is particularly suitable for portable fire extinguishing equipment, ensuring stability and reliability during long-term use. The diaphragm design of the pump enables it to effectively avoid liquid leakage problems and reduce the frequency of maintenance and loss.

[0042] Preferably, the L-shaped right-angle joint 14 is used to adjust the direction of the pipeline to facilitate flexible layout in a space-constrained environment.

[0043] Preferably, the matching design of the quick connector female connector 15 and the quick connector male connector 16 makes it easier and faster to connect and disassemble the fire extinguishing agent storage tank 9 to the liquid supply system, which is convenient for operators to quickly replace empty tanks.

[0044] Preferably, the quick connector male connector 16 has a built-in four-point quick-plug nipple ball valve, which is designed to quickly cut off the flow of fire extinguishing agent when connecting or disconnecting, ensuring the safety and convenience of the system. The four-point quick-plug nipple ball valve can realize instant opening and closing of the liquid channel through a simple plug-in action, reducing the risk of liquid leakage during operation. This design effectively avoids the waste of fire extinguishing agent and can quickly stop the flow of liquid when quickly replacing the fire extinguishing spray gun or other components, thereby improving the overall operating efficiency and safety of the system. The ball valve is made of corrosion-resistant material and can withstand the chemical composition of the fire extinguishing agent, ensuring reliability and stability in long-term use.

[0045] Preferably, the fire extinguishing spray gun 7 is made of corrosion-resistant metal (copper) material, which has excellent durability and corrosion resistance. Through the swirl nozzle design, the spray gun can accurately adjust the spraying angle within the range of 0-60° to adapt to the extinguishing needs of different fire sources and enhance the fire extinguishing effect. The fire extinguishing spray gun can achieve a water flow output of 10 liters per minute, ensuring rapid coverage of the fire source area and significantly improving the fire extinguishing efficiency. The nozzle of the fire extinguishing spray gun adopts a six-hole fine mist spraying design, which can disperse the water flow into a uniform fine water mist, increase the contact area of ​​the fire extinguishing agent, and improve the fire extinguishing effect. The six-hole nozzle design helps to form a more uniform water mist, improve coverage and permeability, and enhance the fire extinguishing efficiency of the fire extinguishing agent mist on the fire source.
