[0021] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, the low-recoil fire-fighting bombs launched by drones include:

[0023] A projectile 2 and an unmanned vehicle, wherein the unmanned vehicle comprises an unmanned vehicle body and a rack for mounting the projectile 2;

[0024] A propulsion assembly, the front end of which is connected to the projectile 2, and a water storage box 5 is provided inside the propulsion assembly, wherein a cavity is provided inside the water storage box 5 for placing a water bag 51;

[0025] The launch tube 1 is arranged outside the projectile body 2 and the propulsion assembly.

[0026] In this embodiment, a low-recoil fire-extinguishing bomb mounted and launched by a drone is provided with a water storage box 5 in the propulsion assembly, and a cavity is provided inside the water storage box 5 for placing a water bag 51. That is, the low-recoil fire-extinguishing bomb mounted and launched by the drone adopts a water rocket-assisted launch method for the projectile 2, so that the friction between the projectile 2 and the launch tube 1 is smaller, so that the force between the projectile 2 and the launch bracket during launch is smaller, which solves the problem of the large overturning force of the projectile 2 on the unmanned vehicle and keeps the unmanned vehicle stable; a water storage box 5 is provided in the propulsion assembly, and the water storage box 5 is a non-uniform-diameter rotating cylindrical body, and a water bag 51 can be stored inside, which can reduce the temperature of the high-temperature and high-pressure gas ejected when the projectile 2 is launched, thereby improving the launch safety of the projectile 2 and improving the fire extinguishing effect.

[0027] In one embodiment, the propulsion assembly includes a booster 4, a nozzle 3, and a booster spacer 6. The booster spacer 6 is disposed between the booster 4 and the projectile 2. The rear end of the booster 4 is connected to the nozzle 3. The booster spacer 6 is cylindrical and made of a shock-absorbing material. The nozzle 3 has a structure in which the front half gradually tapers toward a narrow throat, then gradually widens outward to the base of the arrow. The rear end of the booster 4, which is connected to the nozzle 3, is threaded. The projectile 2 includes a rear cover 22 and a tail fin 25. The tail fin 25 is used to support the projectile 2 to reduce the contact surface between the projectile 2 and the launch tube 1.

[0028] In one embodiment, an igniter 41 and a gas generator 42 are provided in the booster 4 . The igniter 41 is connected to the gas generator 42 . The igniter 41 is used to discharge and ignite the gas generator 42 .

[0029] Furthermore, the booster 4 has a front end, and the front end is in the shape of a cylindrical boss connected to the projectile 2.

[0030] In this embodiment, the discharge of the igniter 41 ignites the gas generator 42, and the gas generator 42 instantly generates a large amount of high-pressure and high-temperature gas, which is ejected along a predetermined path. The water bag 51 in the water storage box 5 is broken during the process of the high-temperature and high-pressure gas being ejected along the inner wall of the nozzle 3, and the high-temperature and high-pressure gas is instantly generated to push the water flow out from the rear end of the nozzle 3, thereby generating thrust in the opposite direction to push the projectile 2 to complete the launch.

[0031] In one embodiment, the projectile 2 has a shell 21, a detonator 28 is provided at the bottom of the central axis of the projectile 2, and the projectile 2 further includes:

[0032] A gas generator 29 is provided outside the detonator 28;

[0033] The airbag 24 is provided outside the gas generator 29, and a fire extinguishing agent 26 is provided between the outside of the airbag 24 and the inside of the shell 21;

[0034] The delayed discharge component 27 is connected to the detonator 28. The delayed discharge component 27 is used to set the explosion delay time and discharge to trigger the detonator 28 to explode when the explosion delay time ends.

[0035] In this embodiment, a cavity is defined within the projectile body 2, with a detonator 28 positioned at the bottom of the cavity's central axis. A gas generator 29 is wrapped around the detonator 28. The airbag 24 exhibits excellent impact resistance, and the fire extinguishing agent 26 can be a dry powder fire extinguishing agent 26, a foam fire extinguishing agent 26, or the like. It is understood that the delayed discharge assembly can be configured with a delay time for the projectile body 2 to explode. At the end of the delay time, a discharge occurs, triggering the detonator 28 to explode. The explosion of the detonator 28 then detonates the gas generator 29, which instantly generates a large amount of high-pressure, high-temperature gas, inflating the airbag 24 and exploding the shell 21, dispersing the fire extinguishing agent 26 and ultimately extinguishing the fire.

[0036] In one embodiment, the projectile 2 has a projectile front end 23, and the low-recoil fire-extinguishing bomb mounted and launched by the drone further includes a spring pin 7, which is disposed at the projectile front end 23. The spring pin 7 has the functions of positioning and partially fixing the projectile. When the projectile 2 is in the launch tube 1, the spring pin 7 can support the projectile front end 23; after the projectile 2 is launched, it can prevent the projectile 2 from rotating.

[0037] The low-recoil fire-extinguishing bomb mounted and launched by the drone in the present invention adopts a water rocket-assisted launch method for the projectile 2, which makes the friction between the projectile 2 and the launch tube 1 smaller, and thus makes the force between the projectile 2 and the launch bracket smaller during launch, thereby solving the problem of large overturning force on the unmanned vehicle when the projectile 2 is launched, so as to keep the unmanned vehicle stable, improve the adaptability environment of the fire-extinguishing bomb, reduce the requirements for the unmanned vehicle and the fire-fighting cost; a water bag 51 is provided in the propulsion assembly to reduce the temperature of the high-temperature and high-pressure gas ejected when the projectile 2 is launched, thereby improving the launch safety of the projectile 2 and improving the fire-fighting effect.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
