[0022] 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.

[0023] Please see Figures 1-7 As shown, this utility model provides the following technical solution:

[0024] A drone-borne covering fire extinguishing projectile includes a projectile body 1 mounted on a drone. One end of the projectile body 1 is equipped with a stabilizing component 2 for stabilizing itself. The projectile body 1 includes a shell portion and an ignitable fire extinguishing portion. The fire extinguishing portion is installed inside the shell portion. The outer circumference of the shell portion is arranged in a ring array to form multiple side grooves 12. An external attachment 3 is rotatably connected inside the side grooves 12. The connection between the external attachment 3 and the side grooves 12 is located at the highest position inside the side grooves 12. The external attachment 3 includes a rotating plate 31. The rotating plate 31 is recessed to form a cavity 34. The cavity 34 is filled with a second fire extinguishing agent layer 36. A second gunpowder layer 35 is disposed inside the second fire extinguishing agent layer 36. A second lead wire 37 is connected to one side of the second gunpowder layer 35. The free end of the second lead wire 37 extends to the outside of the second gunpowder layer 35.

[0025] With the above technical solution, when personnel need to extinguish fires using fire extinguishing bombs, the fire extinguishing bombs are mounted on drones. The drones carry the fire extinguishing bombs and move them above the fire source. The drones then drop the fire extinguishing bombs. As the fire extinguishing bombs fall downwards, the rotating plate 31 rotates under the action of airflow, causing the rotating plate 31 to unfold. The rotating plate 31 stabilizes the shell part, allowing it to move stably and fall steadily into the fire source. The fire source ignites the fire extinguishing component inside the shell part, causing it to explode and extinguish the fire. When the fire extinguishing component explodes, the rotating plate 31 explodes in all directions, and the flames ignite the second fuse 37, which in turn ignites the second gunpowder layer 35, thereby exploding the second extinguishing agent layer 36 and further extinguishing the fire source, thus expanding the fire extinguishing range of the fire extinguishing bomb.

[0026] In order to facilitate the ignition of the second gunpowder layer 35 inside the rotating plate 31, such as Figures 6-7 As shown, one side of the rotating plate 31 is open to form a side hole 32, one end of the second lead wire 37 extends into the interior of the side hole 32, and a removable sealing plug 33 is provided inside the side hole 32.

[0027] In this embodiment, before personnel attach the fire extinguishing bomb, they pry open the sealing plug 33 to expose the side hole 32, thereby exposing the second lead wire 37, and then attach the fire extinguishing bomb to the drone for normal use.

[0028] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-5 As shown, the shell portion includes a cartridge case 11, a side groove 12 is formed on the outer peripheral surface of the cartridge case 11, and a hollow inner cavity 15 is formed inside the cartridge case 11, with the fire extinguishing part filling the interior of the inner cavity 15.

[0029] In this embodiment, when personnel need to carry fire extinguishing bombs, the shell 11 is connected to the drone. The fire extinguishing part is contained in the inner cavity 15 inside the shell 11. When the drone drops the fire extinguishing bomb above the fire source, the fire source ignites the fire extinguishing part, thereby extinguishing the fire.

[0030] Furthermore, regarding the aforementioned fire extinguishing component in this utility model, as follows: Figure 5 As shown, the fire extinguishing part includes a first extinguishing agent layer 18, which fills the interior of the inner cavity 15. A first gunpowder layer 16 is disposed inside the first extinguishing agent layer 18. A first lead wire 17 is connected inside the first gunpowder layer 16, and the free end of the first lead wire 17 extends to the outside of the first extinguishing agent layer 18.

[0031] In this embodiment, when the cartridge case 11 is dropped onto the fire source, the first fuse 17 is ignited by the flame, which in turn ignites the first gunpowder layer 16, causing the first gunpowder layer 16 to explode the first extinguishing agent layer 18, thereby extinguishing the fire source through the first gunpowder layer 16.

[0032] Specifically, in one embodiment, regarding the aforementioned stabilizer 2, as... Figures 1-5 As shown, the stabilizer 2 includes a base head 21, which is fixedly connected to one end of the cartridge case 11, and multiple stabilizing fins 22 are fixedly connected to the circumferential surface of the base head 21 in a ring array.

[0033] In this embodiment, after the shell casing 11 is dropped by the drone, the base 21 and the stabilizing fins 22 work together to make the fire extinguishing shell more stable during movement, so that the fire extinguishing shell can be stably dropped to the fire source.

[0034] Furthermore, in this invention, to further increase the stability of the fire extinguishing bomb during movement, such as... Figures 1-4As shown, two flow guides 14 are fixedly connected to the end of the cartridge case 11 away from the base head 21. The two flow guides 14 are perpendicular to each other, and the outer peripheral surface of the cartridge case 11 is arranged in a ring array to form multiple flow guide grooves 13. The flow guide grooves 13 are located between two adjacent side grooves 12.

[0035] In this embodiment, after the fire extinguishing bomb is dropped by the drone, the stability of the fire extinguishing bomb during movement is further improved by the cooperation of the flow guide frame 14 and the flow guide groove 13.
