Description

Technical Field

[0001] This invention belongs to the field of fire extinguishing equipment technology, specifically a non-pressurized, pistonless, gunpowder-free perfluorohexanone automatic fire extinguishing device. Background Technology

[0002] With the widespread use of enclosed electrical equipment such as energy storage battery compartments, high and low voltage distribution cabinets, and precision industrial control rooms, electrical fires caused by short circuits and battery thermal runaway are frequent. In such scenarios, the internal components are precision and the equipment is valuable. The extinguishing medium must not produce corrosion or dust residue. At the same time, the device must have the ability to identify fires early, start up quickly, and have no risk of high voltage standby leakage. Perfluorohexanone has become the mainstream extinguishing medium for such scenarios due to its advantages of being clean and residue-free, providing dual fire extinguishing through cooling and suffocation, and preventing secondary damage to insulation.

[0003] Currently, the mainstream perfluorohexanone automatic fire extinguishing devices on the market are divided into two main categories: pressurized and non-pressurized. Pressurized devices mix the driving gas and extinguishing agent and store them under pressure for a long time. The containers and pipelines are pressurized all year round, which can easily lead to slow leakage or depressurization failure. Regular pressure testing and maintenance and replacement are required, resulting in high operation and maintenance costs. In addition, high-pressure tanks pose safety hazards in storage, transportation and installation, and are difficult to fit into small cabinets and battery pack compartments, thus limiting their application.

[0004] However, most non-pressurized devices use a piston as the medium-pushing component. The high-pressure gas generated by the gas production pushes the piston to squeeze liquid perfluorohexanone outward. There is a sealing friction gap between the piston and the tank. After high temperature and long-term static storage, the seal is prone to aging and leakage. The gas pressure is prone to reverse pressure leakage from the piston gap, resulting in a decrease in pushing force. A large amount of liquid extinguishing agent remains in the tank, and the extinguishing dosage is insufficient to continuously suppress high-temperature reignition. At the same time, the piston and sealing ring components are numerous and the assembly is complex. They are prone to jamming in the narrow cavity, causing the device to fail to start. Therefore, this invention provides a non-pressurized, piston-free, gunpowder-free perfluorohexanone automatic fire extinguishing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a non-pressurized, pistonless, gunpowder-free perfluorohexanone automatic fire extinguishing device of the present invention, including a fire extinguishing agent storage tank for storing fire extinguishing agent, an atomizing nozzle for spraying fire extinguishing agent fixedly installed at one end of the fire extinguishing agent storage tank, and a pressurizing device for rapid spraying of fire extinguishing agent provided in the inner cavity of the fire extinguishing agent storage tank. The pressure application equipment includes: A carbon dioxide storage tank is detachably installed inside the fire extinguishing agent storage tank, and a high-purity aluminum membrane for sealing its own inner cavity is fixedly installed at the open end of the carbon dioxide storage tank. A puncture probe for puncturing the high-purity aluminum membrane is provided at the open end of the carbon dioxide storage tank.

[0007] The carbon dioxide storage tank has a limiting shell at its open end. Multiple connecting plates are fixedly installed in a ring at one edge of the limiting shell. The other ends of the connecting plates are fixedly connected to the edge of the open end of the carbon dioxide storage tank. A through hole communicating with its own inner cavity is opened in the middle of the end of the limiting shell near the connecting plates. An elastic plate is fixedly installed in the inner cavity of the through hole. The outer wall of the elastic plate is bent. One end of the piercing probe is fixedly connected to the end of the elastic plate near the carbon dioxide storage tank.

[0008] A miniature airbag is fixedly installed in the inner cavity of the limiting shell. The inner cavity of the miniature airbag is filled with a trace amount of gas-generating agent, and a nickel-chromium heating bridge wire for igniting the trace amount of gas-generating agent is fixedly installed in the inner cavity of the miniature airbag.

[0009] The end of the extinguishing agent storage tank away from the atomizing nozzle has a threaded hole that communicates with its own inner cavity. A sealed tank that communicates with the inner cavity of the threaded hole is fixedly installed in the inner cavity of the carbon dioxide storage tank. The central axis of the sealed tank coincides with the central axis of the threaded hole, and the inner diameter of the sealed tank is the same as the diameter of the threaded hole. The outer wall of the limiting shell has a spiral groove that matches the threaded hole.

[0010] A housing is fixedly installed at the end of the extinguishing agent storage tank away from the atomizing nozzle. A signal processing control circuit board and a start-up output circuit for energizing the nickel-chromium heating bridge wire are fixedly installed inside the housing. An extension rod is fixedly installed at the end of the housing away from the carbon dioxide storage tank. A detection sensor for real-time monitoring of temperature and smoke is fixedly installed at the end of the extension rod away from the housing.

[0011] The fire extinguishing agent storage tank has a limiting hole at the edge of the end away from the atomizing nozzle, which is connected to its own inner cavity. A duckbill-type liquid level switch is detachably installed in the inner cavity of the limiting hole. A storage tank for storing perfluoroacetone is fixedly installed on the inner wall of the carbon dioxide storage tank. The detection probe of the duckbill-type liquid level switch is immersed in the liquid perfluoroacetone.

[0012] The inner wall of the extinguishing agent storage tank is fixedly installed with a mounting shell. The outer wall of the mounting shell is fixedly installed with a connecting pipe that communicates with its own inner cavity along its own tangent position. The end of the connecting pipe away from the mounting shell is fixedly connected to the outer wall of the sealed tank. Turbofan blades are rotatably installed in the inner cavity of the mounting shell through a rotating shaft, and an exhaust pipe that communicates with its own inner cavity is fixedly installed on the outer wall of the mounting shell.

[0013] One of the rotating shafts is fixedly mounted on one end of the shaft extending to the outside of the mounting housing. A second bevel gear, which meshes with the first bevel gear, is rotatably mounted on the outer wall of the mounting housing. A spiral stirring rod for agitating the extinguishing agent is fixedly mounted on one end of the second bevel gear.

[0014] A sealing shell for protecting bevel gears one and two is fixedly installed at one end of the mounting housing near bevel gear two, and the outer wall of the spiral agitator is rotatably connected to the outer wall of the mounting housing.

[0015] Both the inner wall of the air outlet pipe and the inner wall of the atomizing nozzle are fixedly installed with sealing films.

[0016] The beneficial effects of this invention are as follows: 1. The extinguishing agent storage tank has no pre-charge pressure under normal conditions. The carbon dioxide storage tank is independently sealed and completely isolated from the liquid perfluorohexanone extinguishing agent, eliminating the problems of long-term pressurized leakage and depressurization failure from the root cause, and significantly extending the equipment operation and maintenance cycle. At the same time, it abandons the piston push structure and gunpowder and pyrotechnic drive structure of traditional fire extinguishing devices, eliminating piston seal aging, mechanical jamming, and incomplete spraying failure caused by reverse pressure relief. Moreover, it relies on a trace amount of gas-generating agent in conjunction with nickel-chromium heating bridge wire to achieve clean drive. The gas combustion produces no hard residue or corrosive smoke, and will not clog the atomizing nozzle, contaminate the extinguishing agent, or damage precision electrical components, effectively avoiding secondary damage to the equipment and adapting to the long-term protection conditions of high-precision sealed electrical equipment.

[0017] 2. The high-pressure carbon dioxide gas released through tangential air intake drives the turbine blades to rotate at high speed, achieving secondary shear atomization of the gas-liquid mixed extinguishing agent, refining the droplet size, and improving vaporization heat absorption efficiency. Simultaneously, through the linkage transmission of bevel gear one and bevel gear two, the spiral stirring rod synchronously stirs the extinguishing agent in the tank, significantly increasing the mixing contact area between carbon dioxide and liquid perfluorohexanone, achieving uniform fusion of gas and liquid media, ensuring stable pressure establishment in the tank and sufficient spray power, effectively eliminating fire extinguishing dead zones and suppressing fire reignition. In addition, a duckbill-type liquid level switch is installed to monitor the agent level in real time. After the agent is emptied, the switch contacts are permanently locked and continuously output spray feedback signals, allowing the fire protection system to retain spray records for a long time, facilitating post-fire review, equipment maintenance, and agent replacement by personnel. This achieves closed-loop control of the entire fire extinguishing process, significantly improving the intelligence and practicality of the equipment. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-7 As shown in the figure, an automatic perfluorohexanone fire extinguishing device without pressure storage, piston, or gunpowder drive in an embodiment of the present invention includes a fire extinguishing agent storage tank 1 for storing the fire extinguishing agent. The fire extinguishing agent storage tank 1 has a sealed pressure-resistant tank structure and is mainly used for the normal sealed storage of liquid perfluorohexanone fire extinguishing agent. There is no pre-charge pressure inside the tank under normal conditions, which avoids the problems of long-term pressurized leakage and depressurization failure of traditional pressurized devices from the root. The equipment is safer when stored statically and has a longer operation and maintenance cycle.

[0023] Atomizing nozzle 2 is fixedly installed at the bottom of the fire extinguishing agent storage tank 1. The atomizing nozzle 2 is the final spray output component of the fire extinguishing agent, which is used to initially atomize the mixed and pressurized gas-liquid two-phase fire extinguishing agent to achieve uniform spraying of the fire extinguishing agent and avoid the scouring damage to precision equipment caused by direct spraying of liquid agent. A sealing membrane 17 is fixedly installed on the inner wall of the atomizing nozzle 2. Under normal conditions, the sealing membrane 17 completely blocks the channel of the atomizing nozzle 2, preventing external dust and water vapor from entering the tank and preventing nozzle blockage and fire extinguishing agent contamination. Only when an effective spray pressure is established in the tank can the high-pressure medium break through the sealing membrane 17 to complete the spraying operation.

[0024] The inner cavity of the extinguishing agent storage tank 1 is equipped with a pressurizing device, which is the core of the device's fire extinguishing spray. It abandons the traditional piston-pushing structure and solid gunpowder-driven structure, and adopts carbon dioxide gas pressure boosting drive throughout the process. There is no risk of mechanical jamming and no gunpowder combustion residue, which greatly improves safety and cleanliness. The pressurizing device includes a carbon dioxide storage tank 5 that is detachably installed on the top of the inner cavity of the extinguishing agent storage tank 1. The carbon dioxide storage tank 5 is an independent sealed body, completely isolated from the liquid perfluorohexanone extinguishing agent below. It is internally encapsulated with high-pressure liquid carbon dioxide. The tank body is normally independently sealed and there is no pressure leakage.

[0025] A high-purity aluminum membrane 14 is fixedly installed at the open end of the carbon dioxide storage tank 5. The high-purity aluminum membrane 14 is the core sealing component of the tank body, which has excellent airtightness and can stably seal high-pressure liquid carbon dioxide for a long time, preventing gas leakage in the static state. At the same time, the high-purity aluminum membrane 14 is thin and brittle, and can be quickly punctured by a small axial thrust, without the need for a large impact force structure, which is suitable for micro-volume gas production driving conditions. A puncture probe 22 is correspondingly set at the open end of the carbon dioxide storage tank 5. The tip of the puncture probe 22 has a sharp structure, which is used to accurately puncture the high-purity aluminum membrane 14, release the high-pressure carbon dioxide gas in the tank, and provide pressurization power for the fire extinguishing agent spray.

[0026] A limiting shell 8 is fixedly installed at the open end of the carbon dioxide storage tank 5. The limiting shell 8 is an integrated carrier for limiting the movement of the probe and components, which can limit the movement trajectory of the puncture probe 22, ensure that the probe moves vertically downward, and avoid deviation that would cause puncture failure. Multiple connecting plates 11 are fixedly fixed to one edge of the limiting shell 8, and the other end of the multiple connecting plates 11 is fixedly connected to the edge of the open end of the carbon dioxide storage tank 5. The limiting shell 8 is stably fixed through multiple connections, and a gas flow gap is reserved to ensure smooth gas release.

[0027] The limiting housing 8 has a through hole in the middle of one end near the connecting plate 11, which connects to its own internal cavity. The elastic plate 16 with a bending structure is fixedly installed inside the through hole. The elastic plate 16 has elastic reset and force transmission functions. It maintains a stable support state under normal conditions. When subjected to axial thrust, it can deform and press down precisely, driving the piercing probe 22 to move down synchronously. After the thrust is released, it can automatically reset. The structure is simple and there is no mechanical jamming. The top of the piercing probe 22 is fixedly connected to the center of the bottom surface of the elastic plate 16 to achieve precise power transmission.

[0028] A miniature airbag 15 is fixedly installed in the inner cavity of the limiting housing 8. The miniature airbag 15 is a sealed encapsulation structure, filled with a small amount of gas-generating agent. It also has a built-in nickel-chromium heating bridge wire, forming a gunpowder-free electric ignition drive component. The miniature airbag 15 can seal and protect the small amount of gas-generating agent, preventing it from getting damp and failing, and ensuring the long-term reliability of the equipment when stationary.

[0029] Among them, the nickel-chromium heating bridge wire is the core component of electric ignition. It can generate high temperature instantly after being energized, accurately igniting a small amount of gas-generating agent. The combustion of the small amount of gas-generating agent leaves no hard residue or corrosive smoke, unlike traditional gunpowder pyrotechnics. It will not pollute the extinguishing agent, clog the nozzle, or damage the precision electrical equipment. The short-term rapid combustion of the small amount of gas-generating agent can generate a small and stable axial thrust, which pushes the elastic plate 16 to deform and press down, providing sufficient power for the piercing probe 22 to pierce the aluminum film, realizing gunpowder-free power drive.

[0030] The top of the extinguishing agent storage tank 1 has a threaded hole that connects to the inner cavity. The top of the carbon dioxide storage tank 5 is fixedly installed with a sealing tank 4. The central axis of the sealing tank 4 coincides with the threaded hole and the inner diameter matches the diameter of the threaded hole, which can achieve a complete seal at the port and prevent the extinguishing agent and gas from leaking. The outer wall of the limiting shell 8 has a spiral groove that matches the threaded hole. Through the threaded engagement of the spiral groove and the threaded hole, the carbon dioxide storage tank 5 and the limiting shell 8 can be detached and installed as a whole, which is convenient for later equipment maintenance, gas generating agent replacement and component maintenance.

[0031] A housing 9 is fixedly installed on the outer side of the top of the extinguishing agent storage tank 1. The housing 9 is a sealed protective carrier for the control components. The signal processing control circuit board and the start-up output circuit are fixedly installed in its inner cavity to realize the functions of fire signal processing, threshold judgment, and power-on start-up control. The signal processing control circuit board is used to receive detection signals and compare them with preset fire thresholds, and to perform dual parameters of smoke and temperature and logic judgment to prevent false triggering by a single signal. The start-up output circuit is used to accurately provide working current to the nickel-chromium heating bridge wire to realize automated ignition control.

[0032] An extension rod 23 is fixedly installed at the top of the housing 9, and a detection sensor 3 is fixedly installed at the end of the extension rod 23. The detection sensor 3 is preferably a miniature photoelectric smoke and temperature composite sensor, which can collect smoke concentration and ambient temperature data of the protected area in real time. Unlike traditional office ceiling sensors, it has the advantages of analog signal output, dual-parameter detection, and adaptability to the working conditions of sealed cabinets. It can accurately identify electrical smoldering and high-temperature thermal runaway fires, providing accurate signal basis for device startup.

[0033] A limiting hole is provided at the top edge of the extinguishing agent storage tank 1. A duckbill-type liquid level switch 12 is detachably installed inside the limiting hole. The duckbill-type liquid level switch 12 is the core component for feedback of the device's spray status. The interior of the extinguishing agent storage tank 1 is a perfluorohexanone extinguishing agent storage chamber. The detection probe of the duckbill-type liquid level switch 12 is normally completely submerged below the liquid perfluorohexanone surface and can continuously output monitoring signals indicating that the equipment is normal and the agent is sufficient.

[0034] Once the extinguishing agent has been completely discharged and emptied, the liquid level is below the detection probe. The probe loses its liquid sensing medium, and the internal contacts of the switch permanently flip and lock, continuously outputting a feedback signal indicating that the device has completed its discharge. The signal will not automatically reset as the tank cools or the pressure disappears, allowing the fire monitoring system to retain discharge records for a long time. This provides accurate information for post-fire analysis, equipment maintenance, and agent replacement, solving the problems of traditional devices lacking long-term feedback and difficulty in operation and maintenance traceability.

[0035] The inner wall of the extinguishing agent storage tank 1 is fixedly installed with a housing 6. The housing 6 serves as the mounting carrier for the turbine fan and the disturbance component. A connecting pipe 7 is fixedly installed tangentially on its outer wall. The other end of the connecting pipe 7 is fixedly connected to the outer wall of the sealed tank 4. After the carbon dioxide gas is released, it can enter the inner cavity of the housing 6 through the connecting pipe 7 tangentially, forming a swirling air intake effect.

[0036] The turbine blades 18 are mounted on the inner cavity of the housing 6 via a rotating shaft. The high-pressure carbon dioxide gas-liquid mixture tangentially impacts the turbine blades 18, driving them to passively rotate at high speed without the need for an additional motor. The high-speed rotation of the turbine blades 18 shears and breaks down the gas-liquid mixture, refining large perfluorohexanone droplets into micron-sized droplets, achieving secondary deep atomization and significantly improving the vaporization efficiency and fire extinguishing coverage of the extinguishing agent. The outlet pipe 10 is fixedly installed on the outer wall of the housing 6, and the inner wall of the outlet pipe 10 is also fixed with a sealing film 17, which is normally sealed and dustproof, and allows for smooth output of the atomized medium during operation.

[0037] One of the rotating shafts of the turbofan blade 18 extends to the outside of the mounting housing 6, and a bevel gear 21 is fixedly installed at its end. A bevel gear 19 that meshes with the bevel gear 21 is rotatably installed on the outer wall of the mounting housing 6, forming a gear linkage transmission structure. A spiral stirring rod 13 is fixedly installed at the end of the bevel gear 19, and the spiral stirring rod 13 extends into the agent cavity of the fire extinguishing agent storage tank 1.

[0038] While the turbine blades 18 rotate, the spiral stirring rod 13 rotates synchronously through the meshing transmission of bevel gear 21 and bevel gear 19. This continuously stirs and agitates the liquid perfluorohexanone in the tank, significantly increasing the mixing contact area between carbon dioxide and liquid extinguishing agent, achieving full and uniform mixing of gas and liquid, avoiding gas-liquid separation or uneven local agent concentration, and improving the overall spray extinguishing performance.

[0039] A sealing shell 20 is fixedly installed on the outside of the mounting housing 6. The sealing shell 20 completely covers the bevel gear 1 21 and bevel gear 2 19, which can seal and protect the gear transmission structure, prevent jamming and wear caused by the intrusion of extinguishing agent and dust, and ensure the long-term stable operation of the linkage structure. At the same time, the spiral stirring rod 13 is rotatably and sealed to the outer wall of the mounting housing 6 to prevent leakage of the medium inside the tank.

[0040] The working principle of this equipment is as follows: Under normal conditions, the fire extinguishing agent storage tank 1 has no pre-charge pressure inside, the carbon dioxide storage tank 5 is independently sealed and completely isolated from the fire extinguishing agent, the overall equipment is safe to stand still and has no risk of leakage, the detection sensor 3 monitors the smoke and temperature parameters of the protected area in real time, and continuously compares the preset fire threshold through the signal processing control circuit board.

[0041] When an electrical fire occurs in the protected area, and the smoke concentration or ambient temperature simultaneously reaches the set alarm threshold, the control circuit board determines the actual fire situation and supplies power to the nickel-chromium heating bridge wire by activating the output circuit. The bridge wire instantly ignites the trace gas-generating agent inside the micro airbag 15 at high temperature. The trace gas-generating agent burns instantaneously and generates a stable axial thrust, which pushes the elastic plate 16 to deform and press down, causing the piercing probe 22 to move vertically downward and accurately pierce the high-purity aluminum film 14 at the port of the carbon dioxide storage tank 5.

[0042] Inside the carbon dioxide storage tank 5, high-pressure liquid carbon dioxide is rapidly vaporized and released, entering the inner cavity of the mounting shell 6 tangentially through the connecting pipe 7. The high-speed airflow impacts the turbine blades 18, causing them to rotate at high speed and atomize the gas-liquid mixture. At the same time, the gear linkage structure drives the spiral stirring rod 13 to stir the fire extinguishing agent in the tank, further expanding the gas-liquid mixing area and achieving full fusion of carbon dioxide and perfluorohexanone.

[0043] The canister quickly establishes a uniform spray pressure, and the high-pressure mixed medium breaks through the sealing film 17 at the outlet pipe 10 and the atomizing nozzle 2 in sequence. After being finely atomized by the atomizing nozzle 2, it is evenly sprayed onto the fire area. During the fire extinguishing process, carbon dioxide quickly absorbs the heat of the fire to achieve rapid cooling, and perfluorohexanone vaporizes and isolates oxygen to suffocate the fire. The dual action effectively extinguishes electrical fires, and there are no gunpowder combustion residues, so there is no secondary pollution or corrosive damage to precision equipment.

[0044] As the extinguishing agent continues to be sprayed, the liquid perfluorohexanone level in the tank continues to drop. When the agent is completely emptied, the detection probe of the duckbill-type level switch 12 is removed from the liquid medium, the switch contacts are permanently latched and flipped, and the feedback signal of the completion of the device spraying is continuously output and stored in the fire monitoring system for a long time. This facilitates the staff to carry out fire review, equipment maintenance and agent replacement work. The overall fire extinguishing process of the device is closed-loop, safe and reliable, and easy to operate and maintain.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
