Multiple limiting strips 12 are fixedly connected to the bottom surface of the inner wall of the storage trough 9. A bomb-throwing assembly 3 capable of discharging fire extinguishing bombs 8 is provided inside the storage box 2. A feeding assembly 4 capable of intermittently feeding fire extinguishing bombs 8 into the bomb-throwing assembly 3 is provided inside the storage box 2.

[0025] The technical effect achieved by the above embodiment is as follows: by placing the fire extinguishing bomb 8 inside the storage tank 9, the inclined storage tank 9 and the limiting strip 12 can prevent displacement of the remaining fire extinguishing bombs 8 when they are damaged. Then, through the cooperation between the bomb-throwing component 3 and the feeding component 4, the fire extinguishing bombs 8 can be sent out intermittently to suppress the fire and limit the remaining fire extinguishing bombs 8, thereby preventing the fire extinguishing bombs 8 from shaking inside the storage tank 9 and affecting the normal flight of the UAV body 1, thereby improving the accuracy of bomb throwing.

[0026] Example 2

[0027] like Figures 2 to 4 As shown, the forest fire-fighting bomb-dropping drone includes all the contents of Embodiment 1. Furthermore, the bomb-dropping assembly 3 includes a feeding trough 310 and a motor 301. The feeding trough 310 is located inside the storage bin 2 and communicates with the interior of the storage bin 9. One side of the motor 301 is fixedly connected to one side of the storage bin 2. The output end of the motor 301 penetrates the surface of the storage bin 2 and extends into the interior of the feeding trough 310. A transmission rod 302 is fixedly connected to the output end of the motor 301. The end of the transmission rod 302 away from the motor 301 is rotatably connected to one side of the inner wall of the feeding trough 310. A cam is fixedly connected to the rod wall of the transmission rod 302. 303. The bomb-throwing assembly 3 also includes a fixing ring 304, which is fixedly connected to the bottom surface of the storage box 2. The bomb-throwing assembly 3 also includes two mounting grooves 309 formed inside the fixing ring 304. Springs 308 are fixedly connected to opposite sides of the inner walls of the two mounting grooves 309. Baffles 306 are fixedly connected to opposite ends of the two springs 308. Limiting rods 307 are fixedly connected to opposite sides of the two baffles 306. Stop bars 305 are fixedly connected to opposite sides of the two baffles 306. Opposite ends of the two stop bars 305 penetrate one side of the inner wall of the corresponding mounting groove 309 and extend into the interior of the fixing ring 304.

[0028] The technical effect achieved by the above embodiment is as follows: When the feeding component 4 delivers the fire extinguishing bomb 8 into the feeding trough 310, when it encounters a position where fire extinguishing is required, the fixing ring 304 is aligned with the fire source, and then the motor 301 is started. After the motor 301 starts, it drives the cam 303 to rotate through the transmission rod 302. As the cam 303 rotates, it can push the upper fire extinguishing bomb 8 downward. Then, the lower fire extinguishing bomb 8 moves downward under the movement of the upper fire extinguishing bomb 8. When the lower fire extinguishing bomb 8 moves downward, it can simultaneously squeeze the two baffles 305 into the corresponding mounting slots 309 and squeeze the two springs 308. After the lower fire extinguishing bomb 8 is discharged, the two springs 308 extend instantaneously and drive the baffles 305 to move into the fixing ring 304 to limit the subsequent fire extinguishing bomb 8, waiting for the next bombing operation.

[0029] Example 3

One side of each limiting plate 405 is rotatably connected to one side of the control block 404.

[0031] The technical effects achieved by the above embodiments are as follows: After the UAV body 1 completes a bombing operation, the electric telescopic rod 402 starts to retract backward. When the electric telescopic rod 402 retracts, it can drive the control block 404 to rotate through the connecting block 403. Then, the control block 404 causes the front limiting plate 405 to move upward. Then, the fire extinguishing bomb 8 can roll into the inside of the feeding trough 310 after the limit is released. Then, the electric telescopic rod 402 pushes forward to control the rear limiting plate 405 to move upward, so that the rear fire extinguishing bomb 8 enters between the two limiting plates 405 to wait for the next bombing operation. The remaining fire extinguishing bomb 8 in the rear can roll forward due to the inclined storage trough 9, and the setting of the limiting strip 12 can prevent the fire extinguishing bomb 8 from rolling backward.
