[0078] The bomb-throwing assembly 33 includes a push block 331 slidably connected to the inner wall of the bomb-throwing chamber 315. A connecting rod 332 is fixedly connected to the rear side of the push block 331. A rack 333 is fixedly connected to the rear end of the connecting rod 332.

[0081] The buffer assembly 41 includes two buffer boxes 411. Buffer plates 412 are slidably connected to the inner walls of the two buffer boxes 411. The tops of the two buffer plates 412 extend to the outside of the corresponding buffer boxes 411 and are fixedly connected to the UAV body 1.

[0084] In use, first install the bomb dropping box 313 on the UAV body 1 through the installation part 2. When installing the bomb dropping box 313, first place the mounting frame 213 at the bottom of the mounting seat 211, so that the positioning block 212 at the top of the mounting frame 213 is inserted into the installation groove opened at the bottom of the mounting seat 211. Then press the fixed plates 225 on the left and right sides of the mounting seat 211. When the two fixed plates 225 move, they drive the sliding rods 222 to move respectively, so that the ends of the two sliding rods 222 close to each other are inserted into the limiting grooves opened on the left and right sides of the positioning block 212 respectively, thereby limiting the position of the positioning block 212 through the sliding rods 222 and making the positioning block 212 unable to move. When the sliding rods 222 move, they will drive the connecting piece 223 to move, and the connecting piece 223 will drive the first spring 224 to stretch when moving. Finally, fix the fixed plate 225 on the mounting seat 211 through the bolt 226, and the mounting frame 213 can be installed at the bottom of the mounting seat 211. Since the bomb dropping box 313 is installed on the mounting frame 213 through the first rotating shaft 312, the bomb dropping box 313 can be installed on the UAV body 1 through the mounting frame 213; when disassembling the bomb dropping box 313, only need to loosen the bolt 226 and remove the bolt 226. At this time, the fixed plate 225 loses its fixation, and the first spring 224 resets and contracts under its own elastic force, thereby driving the sliding rods 222 to move through the connecting piece 223, so that the sliding rods 222 are disengaged from the positioning block 212. Then move the mounting frame 213 downward or move the UAV body 1 upward to disassemble the bomb dropping box 313.

[0085] Before the bomb dropping box 313 is used for fire extinguishing, first, the fire extinguishing bombs are placed into the bomb dropping box 313 through the loading door 314. Due to the special design inside the bomb dropping box 313, the fire extinguishing bombs entering the bomb dropping box 313 will move closer to the communication groove connecting the bottom of the bomb dropping box 313 and the bomb dropping cavity 315. Since only one fire extinguishing bomb can pass through the communication groove between the bomb dropping box 313 and the bomb dropping cavity 315 at a time, and the push block 331 in the bomb dropping cavity 315 blocks the communication groove between the bomb dropping box 313 and the bomb dropping cavity 315 in the initial state, during the bomb dropping process, the fire extinguishing bombs in the bomb dropping box 313 will enter the bomb dropping cavity 315 one by one. And when not in use, the fire extinguishing bombs will not leave the inside of the bomb dropping box 313. When it is necessary to adjust the bomb dropping angle of the bomb dropping box 313 during the fire extinguishing process, first start the first motor 311. The first motor 311 drives the first rotating shaft 312 to rotate. When the first rotating shaft 312 rotates, it drives the bomb dropping box 313 to rotate, so that the angle of the bomb dropping box 313 can be adjusted. During bomb dropping, first start the second motor 321. The second motor 321 drives the second rotating shaft 322 to rotate. When the second rotating shaft 322 rotates, it drives the half gear 323 to rotate. When the half gear 323 rotates, it will periodically engage with the rack 333. When the half gear 323 engages with the rack 333, it will drive the rack 333 to move. When the rack 333 moves, it will drive the connecting rod 332 and the push block 331 to move. When the push block 331 moves, it will cause the second spring 342 to contract. And when the rack 333 does not engage with the half gear 323, the second spring 342 will reset, thereby driving the push block 331 and the connecting rod 332 to quickly move back to their original positions, making the push block 331 have a thrust force, and then pushing out the fire extinguishing bomb that entered the bomb dropping cavity 315 during the moving process before the push block 331 resets through the thrust force, so as to be dropped to the fire point for fire extinguishing. By continuously starting the second motor 321, the half gear 323 is made to cycle into contact with the rack 333, and a continuous bomb dropping effect can be achieved, thereby improving the fire extinguishing efficiency.

[0086] When the UAV lands, the UAV body 1 drives the buffer plate 412 to move downward through two supporting feet. The buffer plate 412 slides inside the buffer box 411, and the rubber pad 415 contacts the ground first, initially reducing the impact force. As the buffer plate 412 continues to move downward, the damper 413 is compressed, and part of the impact force is converted into heat energy and consumed through its own damping characteristics. At the same time, the third spring 414 is also compressed, using elastic deformation to absorb energy. During this process, the limiting block 422 slides inside the limiting chute 421, restricting the movement direction of the buffer plate 412, preventing it from shifting or shaking, ensuring the stability of the buffering process and the reliability of the buffering effect. At the same time, it also makes the buffer plate 412 can only slide inside the buffer box 411, preventing the buffer plate 412 from detaching from the buffer box 411.
