[0002] As a new industrial technology, fire-fighting drones have been widely used in various fields. In China, many fire-fighting agencies have successfully used drones to conduct fire scene reconnaissance and monitoring, drop rescue supplies, and carry fire-fighting equipment to extinguish fires. By using fire-fighting drones, firefighters can work at heights instead of firefighters, minimizing the need for firefighters to work at heights and avoiding safety accidents.

[0003] Fire accidents are complex disasters, and inspection, detection, firefighting and rescue are extremely challenging. Especially when the fire scene is extremely complex, such as a high-rise indoor fire, the rescue difficulty is greatly increased. The fire scene poses a serious threat to the lives of firefighters. For example, a fire in a chemical laboratory or a lithium battery fire, when the cause of the fire and the actual situation of the disaster are unknown, it is not only difficult for firefighters to carry out rescue, but their lives will also be threatened.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figures 1 to 3 As shown, this embodiment proposes a fire-fighting drone, including a drone 1, a throwing structure 3 and a fire-extinguishing bomb 4. A fixing ring 2 is provided at the inner center of the drone 1, a camera bracket 5 is provided on the inner front side of the drone 1, a servo bracket 7 is provided on the top rear side of the camera bracket 5, the top of the servo bracket 7 is fixedly connected to the servo 8, the servo 8 is electrically connected to the battery 12, the output end of the servo 8 is fixedly connected to the rotating rod 9, a support seat 10 is provided on the inner rear side of the drone 1, the throwing structure 3 is provided on the top of the fixing ring 2, the fire-extinguishing bomb 4 is provided inside the fixing ring 2, 500g of dry powder is installed inside the fire-extinguishing bomb 4, and a card block 13 is symmetrically fixed at the top center of the fire-extinguishing bomb 4. A camera 6 is provided inside the camera bracket 5, and the camera 6 is electrically connected to the battery 12. An electrical compartment 11 is provided on the top of the support seat 10, and a battery 12 is provided on the top of the electrical compartment 11. The outer wall of the battery 12 is coated with an aerogel coating.

[0027] By using the fire extinguishing bombs 4 provided, the drone 1 can quickly drop dry powder fire extinguishing agent at the fire scene to effectively extinguish the fire source.

[0028] The camera 6 equipped on the drone 1 can transmit the fire scene image in real time, allowing the operator to accurately judge the fire intensity and the location of the fire source, and thus perform fire extinguishing operations more accurately. This efficient and accurate fire extinguishing capability not only improves the fire extinguishing efficiency, but also reduces the potential danger to firefighters during the fire extinguishing process.

[0029] Example 2:

[0030] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below for details: The drone 1 includes a drone frame 101, an arm 102, a motor 103, a propeller 104 and a landing gear 105. The four internal corners of the drone frame 101 are respectively provided with arms 102, and the four corners of the bottom of the drone frame 101 are respectively fixedly connected to the motor 103, which is electrically connected to the battery 12. The output end of the motor 103 is fixedly connected to the propeller 104, and the two sides of the bottom of the drone frame 101 are respectively fixedly connected to the landing gear 105. One end of the four arms 102 is respectively fixedly connected to the drone frame 101, and the other end is respectively fixedly connected to the fixing ring 2. The bottoms of the two landing gears 105 are respectively fixedly connected to the buffer pad.

[0031] Example 3:

[0032] The following is a further introduction to the solution in Example 2 in conjunction with the specific working method, which is described below for details: the casting structure 3 includes a fixing frame 301 and a latch 305, the bottom two sides of the fixing frame 301 are respectively fixedly connected to the fixing ring 2, a through slot 302 is provided at the top center of the fixing frame 301, a limit frame 303 is provided on the front side of the through slot 302, the latch 305 passes through the interior of the limit frame 303, and movable slots 306 are respectively provided on both sides of the rear of the latch 305.

[0033] Example 4:

[0034] The solution in Example 3 is further introduced below in combination with the specific working method, as described below for details: the through slot 302 is adapted to be connected with the two card blocks 13, the latch 305 is engaged with the two card blocks 13, the latch 305 is connected to the rotating rod 9 through the connecting line 307, the two movable slots 306 are adapted to be connected with the card blocks 13 respectively, and the latch 305 is movably connected to the limit frame 303.

[0035] The design of the throwing structure 3 is also very clever. Through the coordinated action of components such as the fixing frame 301, the through slot 302, the limit frame 303 and the latch 305, the drone 1 realizes remote control of the throwing structure 3 through components such as the servo 8 and the rotating rod 9, allowing the operator to perform fire-fighting operations from a safe distance, reducing safety risks and achieving rapid and stable delivery of the fire-extinguishing bomb 4. This stable flight and delivery system ensures the stability and reliability of the drone 1 during the fire-fighting process, further improving the fire-fighting effect.

[0036] The drone 1 has the characteristics of strong maneuverability and high flexibility. Since the drone 1 is small in size and compact in structure, it can shuttle back and forth indoors or in small areas. It can be loaded with fire extinguishing bombs and perform remote fire extinguishing tasks in the fire scene. The small drone 1 can effectively reduce manpower consumption and material investment for fire extinguishing, thereby reducing the overall fire extinguishing cost. The fire extinguishing bomb 4 is thrown in a suicide manner at the flame location to control the spread of the fire to a certain extent. When the throwing structure 3 of the drone 1 has problems, the drone 1 can realize suicide fire extinguishing, which not only improves the flexibility and accuracy of fire extinguishing, but also reduces the time that the drone 1 withstands high temperature, thereby increasing the fire extinguishing efficiency. At the same time, suicide fire extinguishing does not need to consider the high temperature resistance of the drone 1 after returning.
