[0042] The first motor 32 is started, and the first motor 32 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the bomb box 2 to rotate, so that the bomb box 2 can be turned up or down.

[0043] refer to Figure 1 and Figure 2A loading port 24 and an ejection port 21 are formed through one side wall of the bomb box 2. The loading port 24 is located above the ejection port 21. A first closed door 14 is hingedly connected to the loading port 24 of the bomb box 2. A partition 26 is fixedly connected inside the bomb box 2. The partition 26 is parallel to a side wall of the bomb box 2 where the ejection port 21 is formed. A plurality of first guide plates 22 and a plurality of second guide plates 23 are fixedly connected to the inner walls of the opposite sides of the bomb box 2 respectively. The plurality of first guide plates 22 and the plurality of second guide plates 23 are arranged in sequence in the vertical direction, and the first guide plates 22 and the second guide plates 23 are staggered.

The lower surface of the pushing block 721 is inclined from the middle toward the opposite sides. The elastic force of the third spring 722 is greater than the elastic force of the second spring 92.

[0055] Before launching the fire extinguishing bomb, the second motor 29 is started, the second motor 29 drives the first bevel gear 81 to rotate, the first bevel gear 81 drives the second bevel gear 82 to rotate, the second bevel gear 82 drives the bidirectional screw 27 to rotate, and the bidirectional screw 27 drives the baffles 7 on both sides to move in relative directions under the guidance of the slide bar 28. During the movement of the baffles 7, the baffles 7 drive the push block 721 to move, and the inclined surface of the push block 721 first contacts the side wall of the bomb shell 5, and under the guidance of the side wall of the bomb shell 5, the push block 721 moves toward When the second moving groove 73 is moved, the third spring 722 is compressed. When the baffles 7 on both sides are in contact, the push block 721 and the slot 531 are aligned and correspond one to one. The third spring 722 releases the elastic force to push the push block 721 to move toward the slot 531. During the movement of the push block 721, the push block 721 pushes the block 91 to move downward, so that the block 91 and the slot 531 are disengaged. At the same time, the baffle 7 blocks the upper end of the bomb shell 5, so that the fire extinguishing bomb at the second guide plate 23 and the auxiliary plate 25 is not easy to fall into the bomb shell 5.

[0056] refer to Figure 4 and Figure 5 The bomb box 2 is slidably connected to a second closed door 15 at the ejection port 21 along the vertical direction. The second closed door 15 is inside the bomb box 2. Two moving rods 16 are fixedly connected to the side of the second closed door 15 facing the inside of the bomb box 2. The moving rod 16 is perpendicular to the second closed door 15. A push rod 17 is rotatably connected to the moving rod 16. The push rod 17 is perpendicular to the moving rod 16. The ends of the two push rods 17 away from the moving rod 16 are respectively hinged to the ends of the two baffles 7 close to the ejection port 21.

[0057] When the baffle plate 7 moves in the relative direction, the baffle plate 7 drives the push rod 17 to move, and under the guidance of the second closed door 15, the push rod 17 flips over, and at the same time, the push rod 17 pushes the second closed door 15 to move upward, so that the second closed door 15 releases the blockage of the ejection port 21. When the baffle plate 7 moves in the opposite direction, the baffle plate 7 drives the push rod 17 to move, and the push rod 17 drives the second closed door 15 to move downward, and the second closed door 15 blocks the ejection port 21.

[0058] The implementation principle of the fire-fighting drone of the present application is as follows: fire-fighting bombs are filled into the bomb box 2 from the filling port 24, and under the guidance of the first guide plate 22 and the second guide plate 23, the first fire-fighting bomb entering the bomb box 2 moves into the bomb shell 5, and the first closed door 14 is closed. The body 1 drives the support rod 13 to move, the support rod 13 drives the first support plate 11 to move, the first support plate 11 drives the second support plate 13 to move, and the second support plate 13 drives the bomb box 2 to move, and the tilting direction is required. When launching the fire extinguishing bomb upward or obliquely downward, start the first motor 32, the first motor 32 drives the rotating rod 31 to rotate, the rotating rod 31 drives the bomb box 2 to rotate, so that the ejection port 21 reaches the set position, the second closed door 15 is opened, and the ejection component 4 ejects the fire extinguishing bomb in the bomb shell 5, so that the fire extinguishing bomb is ejected out of the bomb box 2, and the fire extinguishing bomb is fired obliquely upward or obliquely downward. Through the setting of the rotating component 3, the fire extinguishing bomb can be fired obliquely upward or downward, thereby improving the applicability of the fire-fighting drone.

[0059] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
