[0002] Currently, in some sudden fire scenarios, such as buildings and forests, where space is limited, fire extinguishing bombs with built-in extinguishing agents are thrown to control the local fire and achieve the effect of extinguishing the fire.

[0003] A search revealed a Chinese patent publication number CN220809799U, which discloses a fire extinguishing bomb delivery device, including a drone body, a storage box, a pushing component, and a limiting component. The storage box is fixedly connected to the drone body and has a discharge port located on the side of the storage box near the drone body and extending through the storage box. This patent uses a lifting component to block the edge of the discharge port with a limiting baffle, preventing the fire extinguishing bomb from falling out of the discharge port during the movement of the drone body. However, when the fire extinguishing bombs are pushed toward the discharge port, due to the close arrangement of the fire extinguishing bombs, there may be a situation where after one fire extinguishing bomb is thrown out, the remaining fire extinguishing bombs continue to be thrown out due to their own rolling, resulting in accidental delivery.

[0021] Example 1: A fire extinguishing bomb dispensing device, such as Figures 1 to 4 As shown, the device includes a housing 1. A connecting plate 2 for connecting to a drone is fixedly connected to the top outer wall of the housing 1. Mounting holes are provided at all four corners of the connecting plate 2. A bomb release port 4 is provided at the bottom of one end of the housing 1. A loading component 3 is provided at the end of the housing 1 away from the bomb release port 4. A blocking component 5 is provided on the inner wall of the housing 1 between the loading component 3 and the bomb release port 4. The blocking component 5 includes a cavity 6 and a blocking block 7. The cavity 6 is opened inside the housing 1. The blocking block 7 is vertically slidably connected to the inner wall of the cavity 6. A spring 8 is provided on the inner wall of the cavity 6. The two ends of the spring 8 are connected to the blocking block 7 and the cavity 6, respectively. The top outer wall of the blocking block 7 near the loading component 3 is set as an inclined surface.

[0022] The loading assembly 3 includes a receiving box 9 and a strip-shaped notch 11. The receiving box 9 is slidably fitted to the inner wall of the box body 1. A strip-shaped notch 11 is provided on one side of the receiving box 9. A baffle 12 is slidably connected to the inner wall of the receiving box 9 near the bomb release port 4. A side plate 16 is rotatably connected to the side wall of the receiving box 9. The other end of the side plate 16 is fixedly connected to the receiving box 9 by a hand-tightened bolt. A guide protrusion 10 is provided on the inner wall of the box body 1. A groove is provided on the outer wall of the receiving box 9 that slidably fits with the guide protrusion 10. A handle 13 for gripping is fixedly connected to the outer wall of the receiving box 9.

[0023] The inner wall of the housing 1 is provided with a linear drive assembly 14. The moving end of the linear drive assembly 14 is connected to a push plate 15. The linear drive assembly 14 includes a drive motor, a screw, a moving block, and a slide, etc., to achieve the linear drive effect. The structure of the linear drive assembly 14 is a mature existing technology, so it will not be described in detail here.

[0024] The strip-shaped notch 11 is provided with a clearance groove at the end away from the bomb release port 4 for the push plate 15 to pass through, and the side wall of the box body 1 is provided with multiple limiting components 17 to limit the loading component 3.

[0025] The limiting component 17 includes a rotating rod 19 and a limiting block 20. The rotating rod 19 is damped and rotatably connected to the housing 1, and the limiting block 20 is fixedly connected to the side wall of the rotating rod 19.

[0026] All electrical components in this embodiment are electrically connected to the controller and power supply structure of the UAV, and the controller can be any conventional known device that performs the control function.

[0027] In use, the connecting plate 2 is connected to the belly of the drone with bolts. Then, fire extinguishing bombs are loaded. The drone moves the device above the fire point. The linear drive assembly 14 drives the push plate 15 to move a certain distance. The push plate 15 pushes the fire extinguishing bomb towards the dispensing port 4. The fire extinguishing bomb closest to the dispensing port 4 compresses the blocking block 7 and retracts into the cavity 6. The spring 8 is compressed and deformed. When a fire extinguishing bomb passes the blocking block 7, it falls from the dispensing port 4. The spring 8 pushes the blocking block 7 to pop out and block subsequent fire extinguishing bombs, preventing them from rolling down the dispensing port 4 and causing accidental release. When the fire extinguishing bomb is launched, the rotating rod 19 in the multiple limiting components 17 is rotated in sequence, causing the limiting block 20 to rotate to one side and offset from the loading component 3. At this time, the handle 13 can be held to pull the empty container 9 out of the box 1, and then the fully loaded container 9 is inserted into the box 1. During the insertion process, the guide surface 18 can provide guidance for the container 9, making it easy to align the container 9 with the box 1. After it is fully inserted, the rotating rod 19 is reversed, the guide surface 18 limits the loading component 3, the baffle 12 is pulled out, and the container 9 is connected to the box 1. The fire extinguishing bomb in the container 9 can move towards the bomb release port 4.

[0028] By setting up a blocking component 5, subsequent fire extinguishing bombs are blocked after one fire extinguishing bomb is deployed, thus preventing the fire extinguishing bombs from being accidentally deployed due to their own rolling.

[0029] With the loading component 3 and the limiting component 17, the pre-loaded fire extinguishing bombs can be quickly loaded into the box 1 when loading fire extinguishing bombs, further improving the loading speed and making it more convenient to use.

[0030] By providing a guide surface 18, the receiving box 9 is guided when the loading component 3 is inserted, making it easier to align the receiving box 9 with the box body 1 and facilitate the insertion of the loading component 3.

[0031] Example 2: A fire-fighting drone equipped with the fire extinguishing bomb dispensing device of the above embodiment, including a drone body, the fire extinguishing bomb dispensing device being installed on the belly of the drone body. The drone body is a mature existing technology, so it will not be described in detail here. This embodiment has the fire extinguishing bomb dispensing device of the above embodiment, and therefore has all the beneficial effects of the fire extinguishing bomb dispensing device of the above embodiment, which will not be described in detail here.

[0032] Working principle: In use, the connecting plate 2 is connected to the belly of the drone with bolts. Then, fire extinguishing bombs are loaded. The drone moves the device above the fire point. The linear drive assembly 14 drives the push plate 15 to move a certain distance. The push plate 15 pushes the fire extinguishing bomb towards the dispensing port 4. The fire extinguishing bomb closest to the dispensing port 4 compresses the blocking block 7 and retracts into the cavity 6. The spring 8 is compressed and deformed. When a fire extinguishing bomb passes the blocking block 7, it falls from the dispensing port 4. The spring 8 pushes the blocking block 7 to pop out and block subsequent fire extinguishing bombs, preventing them from rolling down the dispensing port 4 and causing accidental release. When loading fire extinguishing bombs, rotate the rotating rod 19 in the multiple limiting components 17 in sequence, causing the limiting block 20 to rotate to one side and offset from the loading component 3. At this time, you can hold the handle 13 to pull the empty container 9 out of the box 1, and then insert the fully loaded container 9 into the box 1. During the insertion process, the guide surface 18 can provide guidance for the container 9, making it easy to align the container 9 with the box 1. After it is fully inserted, reverse the rotating rod 19, and the guide surface 18 limits the loading component 3, pull out the baffle 12, and make the container 9 connected to the box 1. The fire extinguishing bombs in the container 9 can move towards the bomb release port 4.
