[0002] As forest area increases, the incidence of forest fires is also increasing. Forest fire refers to a fire that loses human control, spreads and expands freely in the woods, and causes harm and losses to the forest, forest ecology and humans. Forest fire is a natural disaster that is highly sudden, destructive, and difficult to handle and rescue. At present, the fighting of forest fires still mainly relies on human sea tactics, and the means of fighting are single; it is even more difficult to fight fires in places where it is difficult for people to enter due to high mountains and dense forests, and when the fire is large, it also poses a great threat to the life safety of rescue personnel. Patent document CN201710019759.8 discloses a fire-extinguishing bomb dropped by a drone, which can be dropped by a drone and explode with a delayed explosion, can be detonated on the ground, and can be detonated in the air, which is suitable for fire fighting and flame retardant work of forest fires. However, the above-mentioned existing technologies do not have the function of controlling the detonation time. They can only be dropped at a suitable height based on the experience of the bombardier, and cannot accurately land above the fire source. Moreover, once an abnormality occurs in the ignition device, it cannot be detonated in time, and a dud may occur, and the fire source cannot be extinguished in time. Therefore, the technical problem that we need to solve now is how to achieve controllable detonation time and reliable detonation method, avoid detonating failed fire-extinguishing bombs, prevent duds, and extinguish the fire source accurately and timely.

[0008] Furthermore, a plurality of steps of different heights are provided on the top of the shell cover, and the bottom of the T-shaped horizontal end of the adjusting column is clamped on the step of corresponding height to adjust the relative position of the adjusting column and the explosive fuse.

[0015] The beneficial effects of the present invention are:

[0016] 1) The fire extinguishing bomb is mounted on the throwing mechanism of the UAV through a load-bearing hanging rope, one end of the detonation rope is fixed to the UAV, and the other end of the detonation rope is connected to the adjustable detonation mechanism. When the throwing mechanism drops the fire extinguishing bomb, the fire extinguishing bomb is dropped downward, and the detonation rope is separated from the fire extinguishing bomb by the use of the descending gravity, thereby starting the adjustable detonation mechanism, and the adjustable detonation mechanism can control the detonation time of the explosion tube, so that the fire extinguishing bomb can fall on the fire source within a suitable time to achieve precise fire extinguishing; at the same time, a means of auxiliary detonation is set to prevent the failure of the adjustable detonation mechanism. The first auxiliary detonation method is to add a collision firing mechanism at the bottom of the explosion tube, which can fall on the fire source and collide with obstacles to detonate when the fire extinguishing bomb is not detonated in time.

[0017] 2) When the fire extinguishing bomb is released, the insulating sheet is pulled out of the insulating sheet slot by the detonation rope, the conductive spring presses the battery against the conductive block, the fuse is instantly energized and heated to detonate the explosive fuse, thereby realizing the ignition function; the burning time of the explosive fuse varies with the position, and the detonation time of igniting different positions is obtained through experiments or calculations, and then the height level of the designed step is correspondingly designed. When in use, the ignition position can be directly adjusted according to the height of the step to control the detonation time of the explosive tube.

[0018] 3) When there is no external force of collision, the safety paper film also prevents the explosion tube from sinking and fixes the position of the explosion tube; when it is subjected to external force of collision, the explosion tube is pressed down due to the strong inertia force, the firing pin pierces the safety paper film to squeeze the ignition powder, and then friction ignites the impact fuse.

[0019] 4) When the present invention is installed, multiple bombs can be assembled together for batch delivery, and the outer periphery is fixed by a square frame, which makes full use of the delivery space and is easy to use; at the same time, the square structure can slow down the rolling tendency of the fire extinguishing bomb after it falls, and prevent the fire extinguishing bomb from continuing to roll away from the fire source area. When the adjustable detonation mechanism and the collision firing mechanism fail, the side explosion fuse can be ignited by the fire source and then explode to spray the fire extinguishing agent.

[0020] 5) When installed for throwing, it can be folded and stored on the side of the shell. When it is thrown, it automatically pops out and unfolds outward to form a balancing tail, which can help the fire extinguishing bomb to keep the descending direction vertical and make the collision firing mechanism face downward.

The number of the side explosion fuses 8 is set to four; the four sides of the shell 11 are provided with an ignition hole 14; the mounting tube 42 is provided with a fuse tube 421 corresponding to each ignition hole 14; the four fuse tubes 421 are located below the adjustment column; each side explosion fuse 8 is arranged in a corresponding fuse tube 421, one end of the side explosion fuse 8 is exposed from the corresponding ignition hole 14, and the other end of the side explosion fuse 8 is connected to the explosion fuse 51.
