Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a gas-generating driven fire extinguishing device. Background Art

[0002] Fire extinguishing devices play a vital role in modern firefighting. They can effectively and quickly respond to and handle initial fires, either automatically or manually. There are many types of fire extinguishing devices, ranging from automatic fire extinguishers to fire extinguishers, depending on their operating principles and applicable scenarios. Gas-generating fire extinguishing devices, on the other hand, use a gas-generating agent to generate a driving gas, which propels the extinguishing agent to rapidly release and extinguish the fire. These devices utilize the rapid expansion of gas generated by a chemical reaction, generating pressure, which sprays the extinguishing agent at high speed toward the source of the fire, quickly controlling and extinguishing the fire.

[0003] After searching, the Chinese patent document announcement number: CN219783603U discloses a gas-driven perfluorohexanone fire extinguishing device, including a tube body; a first and a second threaded joint are respectively provided at both ends of the tube body; the first threaded joint is connected to the terminal cover, and a reagent chamber is provided between the terminal cover and the first threaded joint; an electric ignition head and a self-extinguishing insulation material layer are provided in the reagent chamber; a blind cover is also provided on the terminal cover, and the wire connected to the electric ignition head passes through the blind cover to connect to the external control circuit; aluminum alloy bursting discs are respectively provided on the inner side of the connection between the first and second threaded joints and the tube body; the second threaded joint is connected to the square end cover, and the square end cover is provided with a spray hole. The utility model triggers the electric ignition head to ignite the self-extinguishing insulation material layer to react and generate a large amount of gas, which increases the pressure in the reagent chamber, breaks through the aluminum alloy bursting disc, and squeezes the perfluorohexanone liquid in the long tube to spray out from the spray hole, achieving cooling and fire extinguishing effects; the device has a simple structure and is easy to produce and assemble.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above patents mention in the beneficial effects: "By triggering the electric ignition head to ignite the self-extinguishing insulating material layer, the self-extinguishing insulating material layer reacts to produce a large amount of gas, which increases the pressure in the agent chamber, breaks through the aluminum alloy bursting disc, and squeezes the perfluorohexanone liquid in the long tube to spray out from the nozzle, achieving cooling and fire extinguishing effects; using pressure-free storage, there is no leakage, pressure vessel, etc., and the device structure is simple, which is conducive to production and assembly." Although the above patent automatically cools and extinguishes the fire by spraying the perfluorohexanone liquid from the nozzle, during the actual operation process, the device is susceptible to external collisions, impacts or bumps during transportation or use, resulting in structural damage. This physical damage will cause the pressure vessel to fail to work normally, and may even cause an explosion in extreme cases. For this reason, a gas-driven fire extinguishing device is proposed to solve the above problems. Utility Model Content

[0032] Embodiment 1

[0033] As Figures 1-3 shown, this embodiment provides a gas production-driven fire extinguishing device, including a fire extinguishing device housing 1, which is the basic structure of the entire gas production-driven fire extinguishing device and is used to protect the internal components from the external environment. A plurality of support bars 2 are fixedly connected to the outside of the fire extinguishing device housing 1 to provide support force for the support bars 2. A strip-shaped opening 3 is provided inside the support bars 2 to limit the subsequent components from sliding. Reset components for resetting the subsequent components are fixedly connected to both the upper and lower ends of the support bars 2. A sliding plate 6 is slidably connected to the inner wall of the reset component. The reset component includes a fixed rod 4 for restricting the subsequent components and providing support force for the subsequent components. A first spring 5 is sleeved outside every two fixed rods 4 to limit the first spring 5 so that the first spring 5 can be evenly stressed. The outside of every two fixed rods 4 is respectively slidably connected to the upper and lower ends of one of the sliding plates 6 so that the first spring 5 can slide horizontally. The adjacent sides of the plurality of sliding plates 6 are respectively fixedly connected to the opposite sides of every two first springs 5 to provide a reset force for the sliding plates 6;

[0034] The outer part of the sliding plate 6 is slidably connected to the inner wall of the fixed rod 4, enabling the sliding plate 6 to slide horizontally. Two sliding columns 7 are slidably connected to the inner wall of the support bar 2, enabling the sliding columns 7 to slide stably. The far sides of multiple sliding plates 6 are respectively in contact with the outer parts of every two sliding columns 7. A connecting plate 8 is fixedly connected to the outer part of the sliding column 7 to restrict the connecting plate 8 and prevent it from slipping. The outer parts of every two connecting plates 8 are both slidably connected to the inner wall of one of the support bars 2, enabling the connecting plate 8 to slide horizontally. Protective plates 9 are fixedly connected to the near sides of every two connecting plates 8 for contacting external bumps or impacts. A plurality of support blocks 10 are fixedly connected to the bottom side of the fire extinguishing device housing 1 to provide support force. Support legs 11 are fixedly connected to the bottom side of the support blocks 10 to support the device.

[0035] As Figure 1 and Figure 4 shown, a fixing ring 15 is fixedly connected to the top end of the fire extinguishing device housing 1. A threaded sleeve 16 is threadedly connected to the outer part of the fixing ring 15 for fixing and disassembling the fixing ring 15 and the threaded sleeve 16. A cylindrical cavity 17 is formed inside the threaded sleeve 16 to restrict the movement of components. A resilient component for abutting subsequent components is fixedly connected to the top side of the inner wall of the threaded sleeve 16. The resilient component includes a second spring 18. The top side of the second spring 18 is fixedly connected to the top side of the inner wall of the threaded sleeve 16. The bottom side of the second spring 18 is fixedly connected to a limiting ring 19 to fix and restrict the second spring 18, enabling the second spring 18 to be evenly stressed.

[0037] Working steps

[0038] Step 1: When the exterior is impacted or collided, the protective plate 9 will be touched first. At this time, the protective plate 9 will push the two connecting plates 8 to slide, and then drive the sliding column 7 to slide. During the sliding process of the sliding column 7, it will push the sliding plate 6 to slide. During the sliding process of the sliding plate 6, it will squeeze the two first springs 5, enabling the first springs 5 to store elastic potential energy, which is then given to the sliding plate 6, and the restoring elastic force is transmitted to the protective plate 9, and finally transmitted to the protective plate 9 to offset the external impact or collision, thereby avoiding structural damage caused by the impact or collision.

[0039] Step 2: We hold the threaded sleeve 16 threaded on the outside of the fixed ring 15 to fix the threaded sleeve 16. During the rotation of the threaded sleeve 16, it will drive the second spring 18 to slide, thus driving the limit ring 19 to slide, and then driving the sealing plate 20 to slide and abut against the fixed ring 15. At this time, the sealing plate 20 will receive a reaction force and give the limit ring 19 a force in the opposite direction, so as to be able to abut against the second spring 18, enabling the second spring 18 to store elastic potential energy, and then giving the limit ring 19 a force in the opposite direction, and then pushing the sealing plate 20 to abut against the fixed ring 15, thereby improving the sealing performance of the fixed ring 15 and avoiding air leakage or insufficient airtightness during use, and then improving the efficiency of the device.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
