[0002] Traditional firefighting methods suffer from low efficiency and high personnel safety risks when facing fires in high-rise buildings or complex terrain. In recent years, with the rapid development of drone technology, using drones to carry fire extinguishing bombs for remote firefighting has become a new and effective means of extinguishing fires. However, existing drone-borne fire extinguishing bombs have certain drawbacks. Most of the existing fire extinguishing bombs are manufactured as a single unit, making it impossible to adjust the amount of extinguishing agent carried according to the size of the fire. This can lead to insufficient or excessive dosage, reducing firefighting efficiency. Furthermore, since gunpowder and extinguishing agents have a limited lifespan, they must be discarded as a whole after their expiration, resulting in high operating costs. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, this utility model provides the following technical solution:

[0023] An airborne fire extinguishing projectile with stabilizing fins includes a base component 2 and a projectile component 1 for fire extinguishing. The bottom of the base component 2 is recessed to form a first connecting hole 27, and a first connecting rod 12 is fixedly connected to the side of the projectile component 1 facing the base component 2. The first connecting rod 12 matches the first connecting hole 27. The projectile component 1 includes a shell part, a gunpowder part, and a fire extinguishing agent part. The gunpowder part and the fire extinguishing agent part are both installed inside the shell part, and the first connecting rod 12 is fixedly connected to the outside of the shell part.

[0024] With the above technical solution, when personnel need to extinguish fires using the device, the projectile 1, with an extinguishing agent carrying capacity that meets the personnel's needs, is placed on one side of the base component 2. The first connecting rod 12 on one side of the projectile 1 is inserted into the first connecting hole 27 on the base component 2. The projectile 1 is rotated, thereby allowing the first connecting rod 12 to be screwed into the first connecting hole 27, fixing the projectile 1 to one side of the base component 2. The base component 2 and the projectile 1 are then mounted on a drone, which carries them to the location of the fire. The drone then uses a delivery device to drop the base component 2 and the projectile 1 to the location of the fire. The flames ignite the gunpowder inside the casing, causing the gunpowder to explode and ignite the extinguishing agent. The extinguishing agent then extinguishes the nearby flames, thus completing the fire extinguishing operation.

[0025] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-4As shown, the shell portion includes a cartridge case 11, one end of which is open to form an inner cavity 111. A first connecting rod 12 is fixedly connected to one side of the cartridge case 11, and the first connecting rod 12 is located at the end of the cartridge case 11 away from the inner cavity 111. A bottom shell 18 for shielding the inner cavity 111 is screwed onto one end of the cartridge case 11.

[0026] In this embodiment, when the device has not been used for a long time, if the gunpowder and extinguishing agent parts have expired and need to be replaced, the bottom shell 18 is rotated to separate the bottom shell 18 from the cartridge case 11, thereby exposing the inner cavity 111 at one end of the bottom shell 18. The expired gunpowder and extinguishing agent parts are then removed from the inner cavity 111, and the usable gunpowder and extinguishing agent parts are placed in the inner cavity 111. The bottom shell 18 is then placed on one side of the cartridge case 11, and the bottom shell 18 is rotated to screw the bottom shell 18 and the cartridge case 11 together, thus completing the installation of the extinguishing agent and gunpowder parts.

[0027] Furthermore, regarding the aforementioned fire extinguishing agent portion in this utility model, as follows: Figures 3-4 As shown, the extinguishing agent portion includes a second inner shell 16, the interior of which is filled with extinguishing agent 113, and one side of the second inner shell 16 is recessed to form an inner groove 17 for accommodating the gunpowder portion.

[0028] In this embodiment, when personnel need to replace the extinguishing agent and gunpowder components, the bottom shell 18 is rotated to separate it from the cartridge case 11, exposing the inner cavity 111 at one end of the bottom shell 18. The second inner shell 16 is then removed from the inner cavity 111, and the gunpowder component is removed from the inner cavity 111. The usable gunpowder component is then placed in the inner cavity 111, and the second inner shell 16 is placed in the inner cavity 111, with the gunpowder component positioned in the inner groove 17 of the second inner shell 16. The bottom shell 18 is then screwed into the cartridge case 11, thus completing the replacement of the gunpowder component, the second inner shell 16, and the extinguishing agent 113. When the device is thrown into the flame by a drone, the gunpowder component is ignited by the flame combustion device, causing an explosion that blasts open the second inner shell 16, allowing the extinguishing agent 113 to extinguish the flame.

[0029] Specifically, in one embodiment, regarding the aforementioned gunpowder portion, as... Figure 3 and Figure 4 As shown, the gunpowder part includes a first inner shell 13, the interior of which is filled with gunpowder 112, and a lead wire 15 is provided on the exterior of the first inner shell 13, one end of which extends into the interior of the first inner shell 13 and contacts the gunpowder 112.

[0030] In this embodiment, when it is necessary to replace the extinguishing agent and gunpowder components, the bottom shell 18 is rotated to separate it from the cartridge case 11, thereby exposing the inner cavity 111 at one end of the bottom shell 18. The second inner shell 16 is then removed from the inner cavity 111, and the first inner shell 13 is removed from the inner cavity 111. The first inner shell 13, which is now in normal working order, is placed in the inner cavity 111, and the second inner shell 16 is placed in the inner cavity 111, with the first inner shell 13 positioned in the inner groove 17 of the second inner shell 16. The bottom shell 18 is then screwed into the cartridge case 11, thus completing the replacement of the first inner shell 13, gunpowder 112, second inner shell 16, and extinguishing agent 113. When the device is thrown into the flame by a drone, the fuse 15 is ignited by the flame combustion device, causing the gunpowder 112 to explode and blast open the second inner shell 16, allowing the extinguishing agent 113 to extinguish the flame.

[0031] After the first inner shell 13 is installed inside the inner cavity 111, in order to increase the stability of the first inner shell 13, such as Figures 3-4 As shown, an inner rod 19 is fixedly connected inside the inner cavity 111. One end of the inner rod 19 is recessed to form a second connecting hole 110. One end of the first inner shell 13 is fixedly connected to a second connecting rod 14, which matches the second connecting hole 110.

[0032] In this embodiment, after the personnel place the first inner shell 13 into the inner cavity 111, the second connecting rod 14 at one end of the first inner shell 13 is screwed into the second connecting hole 110 on the second connecting rod 14 to make the first inner shell 13 more stable after being installed inside the inner cavity 111.

[0033] Specifically, in one embodiment, regarding the aforementioned base component 2, as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the base component 2 includes a base 21, a first connecting hole 27 is formed on one side of the base 21, and two first stabilizing wings 22 are symmetrically fixedly connected to the end of the base 21 away from the first connecting hole 27. A guide fan 24 is rotatably connected to one side of each of the two first stabilizing wings 22.

[0034] In this embodiment, when personnel need to connect the cartridge case 11 to the base 21, the first connecting rod 12 on the cartridge case 11 is screwed into the first connecting hole 27 on the base 21, thereby fixing the cartridge case 11 to one side of the base 21. Then, the base 21 and the cartridge case 11 are installed on the drone. When the drone drops the device to the fire scene, the first stabilizing wing 22 and the deflector fan 24 work together to help the device be dropped more accurately.

[0035] After the device is deployed by a drone, in order to make the device's movement trajectory easy to detect, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, two second stabilizing wings 23 are symmetrically fixedly connected to one side of the base 21. The two second stabilizing wings 23 are located between the two first stabilizing wings 22, and each of the two second stabilizing wings 23 is connected to a connecting rope 25 on one side. A marker 26 is fixedly connected to the free end of the connecting rope 25.
