The fire extinguishing bomb 2 includes: a bomb body 8, an extension rod 7, a lifting ring component, a control component, a speed measuring device, a bottom cover 13, a distance measuring device, and a gas detonating device 11.

[0037] like Figure 5 As shown, the projectile is spherical, generally ellipsoidal, and has a receiving cavity; wherein the upper half of the projectile is provided with a reinforcing beam 14; preferably, the wall thickness of the upper half of the projectile is greater than that of the lower half. A crack groove 15 is provided on the wall of the lower half of the projectile to ensure that the lower half of the projectile is easier to break.

[0038] An upper mounting hole is provided on the top of the projectile body for installing a lifting ring component, and a lower mounting hole is provided at the bottom of the projectile body; dry powder fire extinguishing agent is canned into the accommodating cavity through the lower mounting hole; the lifting ring component includes a lifting ring 3, a lifting ring base 5 and a load-bearing fixed cover 6, the upper mounting hole is provided with a limiting groove, the lifting ring base is installed in the limiting groove, the lifting ring base is self-threaded and rotatably installed on the extension rod, the lifting ring is fixed on the lifting ring base and the top of the lifting ring extends out of the projectile body; the load-bearing fixed cover is used to lock the lifting ring base in the limiting groove.

[0039] The extension rod is arranged in the accommodating cavity; a mounting groove is arranged at the bottom of the extension rod; the lifting ring component is arranged at the top of the projectile body and connected to the top of the extension rod; the control component is arranged in the mounting groove; the speed measuring device is arranged on the control component; the gas detonating device is arranged in the mounting groove; the gas detonating device is connected to the control component; the bottom cover is arranged at the bottom of the projectile body for sealing the mounting hole; the distance measuring device is arranged in the mounting cavity and connected to the bottom cover; the distance measuring device is connected to the control component. The control component also includes a power switch 4, which is arranged on the lifting ring component, and the power switch is connected to the main control board through a connecting line, and the connecting line runs through the extension rod.

[0040] In some embodiments, the control component includes a battery 9 and a main control board 10. The battery is fixed in a mounting slot by a clip. The main control board and a gas detonation module are sequentially installed in the mounting slot and fixed by screws.

[0041] In some embodiments, the speed measuring device is an acceleration measuring module, which is used to measure the acceleration of the projectile when it is in free fall. The distance measuring device is a millimeter radar module 12, which is used to measure the distance between the projectile and the ground.

[0042] Figure 1 The fire extinguisher bomb and the drone shown in the figure are two different devices. When not in use, the two devices are separated and the fire extinguisher bomb is powered off.

[0043] When using, mount the fire extinguisher bomb on the drone's hanging buckle. Figure 1 shown.
