Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fire extinguishing bombs, more specifically, relates to a fire extinguishing bomb launched by a UAV. BACKGROUND

[0002] In the modern fire fighting field, in the face of increasingly complex and diversified fire scenes, the traditional fire extinguishing methods and equipment expose many problems, especially in the application scene of launching fire extinguishing bombs by using UAVs, these problems seriously affect the fire extinguishing efficiency, precision, and the universality and connection stability of the equipment.

[0003] Problems of fire extinguishing bomb launching and extinguishing effect

[0004] Low accuracy of fire extinguishing bomb landing point: in the process of launching traditional fire extinguishing bombs by using UAVs, there is a lack of effective stable flight control mechanism. When the fire extinguishing bomb falls, it is easily affected by external factors such as airflow and wind direction, resulting in unstable flight trajectory, making it difficult to accurately hit the fire source and reducing the fire extinguishing efficiency. In some complex terrain or large fire sites with turbulent airflow, the fire extinguishing bomb may deviate from the target and cannot timely and effectively put out the fire, so that the fire cannot be timely controlled.

[0005] Limited fire extinguishing range and effect: the design of traditional fire extinguishing bombs may not ensure that the fire extinguishing medium is evenly and widely scattered at the fire source after explosion. The fire extinguishing dust particles and other fire extinguishing medium may not fully cover the fire source, resulting in part of the fire source not being timely extinguished, and easy to appear the phenomenon of rekindling. Especially for large area fire, the fire extinguishing range and effect of traditional fire extinguishing bombs are difficult to meet the actual demand.

[0006] Flight stability problem of fire extinguishing bomb

[0007] Insufficient balance and stability measures: traditional fire extinguishing bombs only rely on simple shape design to maintain balance during flight, lack of active stability adjustment device. When encountering complex weather conditions or sudden airflow changes, the fire extinguishing bomb is easy to roll and deviate, and cannot maintain a stable flight attitude. This not only affects the landing accuracy of the fire extinguishing bomb, but also may cause the fire extinguishing bomb to explode prematurely or fail to normally reach the target area during flight, reducing the reliability of the fire extinguishing action.

[0008] Lack of precise flight control: existing fire extinguishing bombs are difficult to accurately adjust according to real-time flight state and external environment changes during flight. Unable to actively control the flight direction and speed, the fire extinguishing bomb cannot flexibly respond when facing complex and changeable fire scenes, reducing its ability to adapt to different fire scenes.

[0009] Difficulty in connecting with UAV

[0010] Poor connectivity: Traditional fire extinguishing bombs are often complex and cumbersome to connect with drones, requiring operators to spend considerable time and effort on installation and securing them. In emergency fire situations, this may delay firefighting efforts. Moreover, the complex connection process may increase the risk of connection failure, affecting the smooth progress of firefighting operations.

[0011] Insufficient versatility: Different models and specifications of drones have varying sizes, shapes, and angles in their connecting claws. Traditional fire extinguishing bombs' connecting devices are typically only compatible with specific types of drones, lacking versatility. This limits the combined use of fire extinguishing bombs with different drones, failing to fully utilize the advantages of various drone types and increasing the procurement and maintenance costs of firefighting equipment.

[0012] Poor connection stability: Traditional connection methods may not ensure a stable connection between the fire extinguishing bomb and the drone during flight. Factors such as vibration and airflow during flight can cause the fire extinguishing bomb to loosen or even detach, leading not only to firefighting mission failure but also posing a safety threat to personnel and facilities below. Summary of the Invention

[0013] To address the aforementioned technical problems, this invention provides a fire extinguishing bomb deployed by a drone, thereby resolving the significant shortcomings of existing fire extinguishing technologies that utilize drones to deploy fire extinguishing bombs in terms of deployment effectiveness, flight stability, and connectivity with drones.

[0014] A fire extinguishing bomb deployed by a drone includes a fire extinguishing bomb body, which contains a controller cover, a control outer tube, and a fire extinguishing bomb canister. The control outer tube is fixedly installed on the top of the fire extinguishing bomb canister, and the controller cover is fixedly installed on the top of the control outer tube. An intelligent reaction controller is installed inside the control outer tube and the controller cover. The fire extinguishing bomb canister contains fire extinguishing dust particles and an explosive fuse agent. The top of the explosive fuse agent is fixed inside the control outer tube. There is a certain space between the fire extinguishing dust particles and the top of the fire extinguishing bomb canister. There is a gap between the bottom of the explosive fuse agent and the bottom of the fire extinguishing bomb canister. The fire extinguishing dust particles are wrapped around the explosive fuse agent. Several balancing tail fins are fixedly connected to the outside of the control outer tube, and a flight connection component is fixedly installed on the outside of each balancing tail fin.

[0015] Preferably, the flight connection assembly includes a micro motor and a fixed vertical pole frame. The fixed vertical pole frame is fixedly connected to the side wall of the stabilizer tail fin. The lower end of each micro motor is fixedly connected to the fixed vertical pole frame. A micro propeller is fixedly installed on the output shaft at the top of each micro motor. An annular groove is opened on the outer ring near the bottom of the micro motor, and a rotating ring frame is rotatably installed in the annular groove. A UAV connector is fixedly installed on both sides of each rotating ring frame, and a connecting bracket is slidably installed on both sides of each UAV connector.

[0016] Preferably, each drone connector has horizontal grooves extending through both sides near the bottom, a transverse connecting frame is fixed between the two connecting brackets, each transverse connecting frame is slidably installed in the horizontal groove, and a micro spring is fixed between each transverse connecting frame and the inner walls at both ends of the horizontal groove. The cross-section of each connecting bracket is an inverted "V" shape, and each connecting bracket protrudes upward in the middle. Each flight connection component is used to connect and install with the drone.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, the fire extinguishing bomb body is connected to a drone. The drone carries the fire extinguishing bomb body into the air. When the drone reaches the fire area, it releases the fire extinguishing bomb body, which then falls towards the fire source. Just before the fire extinguishing bomb body hits the ground, the intelligent reaction controller inside the outer tube simultaneously ignites the explosive fuse agent. The explosive fuse agent explodes inside the fire extinguishing bomb canister. After the fire extinguishing bomb canister explodes, it disperses fire extinguishing dust particles over a wide area. These dust particles land at the fire source, quickly extinguishing the fire.

[0019] In this invention, when the fire extinguishing bomb body falls, the multiple balancing tail fins on the top of the fire extinguishing bomb body can maintain the stability of the fire extinguishing bomb body during flight. At the same time, each balancing tail fin sidewall is equipped with a fixed vertical rod frame, and the miniature propellers on the top of each fixed vertical rod frame can rotate during flight. The miniature motor can drive the four miniature propellers to rotate at a constant speed, thereby maintaining the stability of the fire extinguishing bomb body in the air, thereby improving the ability of the fire extinguishing bomb body to accurately extinguish fire sources.

[0020] In this invention, when connecting the fire extinguishing bomb body and the drone, the drone's connecting claw is connected to two connecting brackets on both sides of the drone connector. Since the connecting brackets are inverted V-shaped, the drone's connecting claw will be stably locked in the recess in the middle of the connecting bracket, thereby improving the ease of connection. At the same time, each connecting bracket can slide in the horizontal groove opened in the drone connector through the transverse connecting frame. Therefore, the connecting brackets can be used for drones of different sizes. Furthermore, a micro spring is provided between each connecting bracket and the drone connector, which can provide greater stability when connected to the drone connecting claw. Each drone connector can rotate in the annular groove opened in the micro motor through the rotating ring frame, thus adapting to different drone claw angles and improving the overall connection capability.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Example 1: Please refer to Figure 1 - Figure 6This invention provides a fire extinguishing bomb deployed by a drone, comprising a fire extinguishing bomb body 8, which includes a controller cover 1, a control outer tube 31, and a fire extinguishing bomb canister 4. The control outer tube 31 is fixedly installed on the top of the fire extinguishing bomb canister 4, and the controller cover 1 is fixedly installed on the top of the control outer tube 31. An intelligent reaction controller 3 is installed inside the control outer tube 31 and the controller cover 1. The fire extinguishing bomb canister 4 contains fire extinguishing dust particles 7 and an explosive fuse agent 5. The top of the explosive fuse agent 5 is fixed inside the control outer tube 31. There is a certain space gap between the fire extinguishing dust particles 7 and the top of the fire extinguishing bomb canister 4, and there is a gap between the bottom of the explosive fuse agent 5 and the bottom of the fire extinguishing bomb canister 4. The fire extinguishing dust particles 7 are wrapped around the explosive fuse. In addition to the agent 5, several balancing tail fins 2 are fixedly connected to the outer circular tube 31. Each balancing tail fin 2 is fixedly equipped with a flight connection component 6. An automatic sensor 81 is installed below the fire extinguishing bomb canister 4. In use, the fire extinguishing bomb body 8 is connected to the drone. The drone carries the fire extinguishing bomb body 8 into the air. When the drone reaches the fire area, it releases the fire extinguishing bomb body 8, and the fire extinguishing bomb body 8 falls towards the fire source. When the fire extinguishing bomb body 8 is about to land, the intelligent reaction controller 3 inside the outer circular tube 31 is controlled to ignite the explosive fuse agent 5. The explosive fuse agent 5 explodes inside the fire extinguishing bomb canister 4. After the fire extinguishing bomb canister 4 explodes, the fire extinguishing dust particles 7 are scattered over a wide area. The fire extinguishing dust particles 7 are scattered at the fire source and quickly extinguish the fire.

[0030] Example 2: Please refer to Figure 1 , Figure 4 Diagram and Figure 6 The flight connection assembly 6 includes a micro motor 61 and a fixed vertical support 69. The fixed vertical support 69 is fixedly connected to the side wall of the stabilizer tail fin 2. The lower end of each micro motor 61 is fixedly connected to the fixed vertical support 69. A micro propeller 62 is fixedly mounted on the output shaft at the top of each micro motor 61. An annular groove 63 is formed on the outer ring near the bottom of the micro motor 61, and a rotating ring frame 64 is rotatably mounted in the annular groove 63. A drone connector 65 is fixedly mounted on both sides of each rotating ring frame 64. Each component is slidably mounted with a connecting bracket 68. During use, when the fire extinguishing bomb body 8 falls, the multiple balancing tail fins 2 on the top of the fire extinguishing bomb body 8 can maintain the stability of the fire extinguishing bomb body 8 during flight. At the same time, each balancing tail fin 2 is equipped with a fixed vertical rod 69 on its side wall. The miniature propellers 62 on the top of each fixed vertical rod 69 can rotate during flight. The miniature motor 61 can drive the four miniature propellers 62 to maintain a constant rotation speed, thereby maintaining the stability of the fire extinguishing bomb body 8 in the air and improving the ability of the fire extinguishing bomb body 8 to accurately extinguish fire sources.

[0031] The intelligent reaction controller 3 is equipped with a drive power supply, which powers the intelligent reaction controller 3 and the four micro propellers 62. When the fire extinguishing bomb body 8 is stored for a long time, the drive power supply will be depleted. At this time, when the fire extinguishing bomb body 8 falls, the four micro propellers 62 will rotate due to the wind. At this time, the four micro propellers 62 will provide reverse power to the drive power supply, which can then drive the intelligent reaction controller 3 again, thereby detonating the fire extinguishing bomb body 8. This improves the fire extinguishing bomb body 8 in the event of a power shortage. At the same time, an automatic sensor 81 is installed at the bottom of the fire extinguishing bomb body 8. The automatic sensor 81 is a miniature sensor that can automatically sense and activate the reaction device to detonate in advance when it is 3-5 meters above the ground during the deployment process, achieving a better fire extinguishing effect.

[0032] Example 3: Please refer to Figure 1 , Figure 5 and Figure 6 Each drone connector 65 has horizontal grooves 66 extending through both sides near the bottom. A transverse connecting bracket 71 is fixed between two connecting supports 68. Each transverse connecting bracket 71 is slidably installed within the horizontal groove 66, and a miniature spring 67 is fixed between each transverse connecting bracket 71 and the inner walls of both ends of the horizontal groove 66. Each connecting bracket 68 has an inverted "V" shaped cross-section and protrudes upwards from the center. Each flight connection component 6 is used for connection and installation with a drone. In use, when connecting the fire extinguishing bomb body 8 to the drone, the drone's connecting claws are connected to the two connecting brackets 68 on both sides of the drone connector 65. The bracket 68 is inverted V-shaped, so the unmanned connecting claw will be stably locked in the recess in the middle of the connecting bracket 68, thereby improving the ease of connection. At the same time, each connecting bracket 68 can slide within the horizontal groove 66 opened in the drone connector 65 through the transverse connecting frame 71. Therefore, the connecting bracket 68 can be used for drones of different sizes. Furthermore, a miniature spring 67 is provided between each connecting bracket 68 and the drone connector 65, which can make the connection with the drone connecting claw more stable. Each drone connector 65 can rotate within the annular groove 63 opened in the miniature motor 61 through the rotating ring frame 64, thus it can be used for different angles of drone claws, improving the overall connection capability.

[0052] I. Analysis of Core Component Functions

[0053] Intelligent reaction control system

[0054] The core module, consisting of the controller cover, the outer control tube, and the intelligent reaction controller, performs a dual task:

[0055] Triggering logic: The system monitors the descent status in real time using built-in sensors and combines this with a preset motion model to precisely activate the detonator at a specific height above the ground. This physics-based triggering mechanism avoids the delay risk associated with traditional fuses that rely on open flames, ensuring that the dust is released directly above the ignition source.

[0056] Energy Management: The outer circular tube serves as a structural support, integrating power and signal lines to provide stable power to the micro motors. Meanwhile, the sliding design of the annular groove allows the UAV connectors to adaptively adjust their angles, ensuring that signal transmission is unaffected by attitude changes.

[0057] Explosion and Fire Suppression Systems

[0058] The fire extinguishing ammunition canister adopts a layered explosive loading structure:

[0059] Explosive detonator: Insensitive high explosive is selected, with the top rigidly connected to the control outer circular tube and the bottom maintaining a gap from the bottom of the tank. This design allows the blast shock wave to propagate axially first, and then torn apart the tank through radial diffusion, forming a "directional blasting" effect, avoiding the uneven distribution of dust caused by energy concentration in a single direction.

[0060] Fire extinguishing dust particles: Utilizing ultrafine powder materials, these particles are arranged in a ring around the explosive fuse, forming an aerosol suspension using the shock wave generated by the explosion. This design significantly expands the dust's diffusion range, prolongs its suspension time, and substantially increases the probability of contact with the flame.

[0061] Flight stability system

[0062] The synergistic effect of the balanced tail fin and micro-blades breaks through the traditional passive stabilization mode of tail fins:

[0063] Aerodynamic compensation: The tail fin adopts a biomimetic airfoil design, which generates lift during descent to offset part of the gravitational acceleration and buy time for dust to disperse.

[0064] Active correction: The micro motor drives the micro blades through speed regulation, adjusts the speed in real time, compensates for crosswind interference, and effectively controls the landing point deviation.

[0065] II. Collaborative Working Mechanism

[0066] Multimodal connectivity technology

[0067] The flight connectivity component achieves reliable coupling with the UAV through a three-level adaptive design:

[0068] Mechanical adaptation: The central groove of the inverted V-shaped connecting bracket forms a geometric lock with the drone claw, and with the preload of the elastic element, it can withstand instantaneous tension.

[0069] Angle compensation: The rotational freedom of the rotating ring frame within the annular groove allows the connector to adapt to the installation angle deviation of different mounting points of the drone, avoiding the risk of detachment due to uneven torque.

[0070] Electrical compatibility: The integrated signal interface supports mainstream communication protocols and can be plugged and played with UAV flight control systems, ensuring that command delays are within a controllable range.

[0071] Dynamic stability control strategy

[0072] During the descent, the intelligent response controller coordinates multiple actuators through algorithms:

[0073] Attitude calculation: The yaw angle is calculated in real time based on inertial data. When the deviation exceeds the threshold, the rotation speed of the corresponding micro-blade is adjusted synchronously to generate lateral force for correction.

[0074] Energy distribution: The motor power is dynamically adjusted through the current monitoring module to optimize power consumption while maintaining stability, thus ensuring the battery life for a single mission.

[0075] III. Breakthrough in Innovative Design

[0076] Modular quick replacement

[0077] The fire extinguishing agent canister and control outer tube use a standardized interface and a sealed design, allowing for rapid refilling. This design enables the same control system to be compatible with various fire extinguishing agents, enhancing emergency response flexibility.

[0078] Anti-interference transmission link

[0079] The combination of sliding structure and elastic element in the drone connector not only adapts to different drone claw sizes, but also reduces the interference of high-frequency vibration on signal transmission through mechanical buffering, ensuring communication stability.

[0080] Safety Redundancy Design

[0081] Dual triggering: In addition to the intelligent reaction controller, the explosive detonator also has a built-in mechanical firing pin mechanism. When no electronic signal is received, the impact of the canister hitting the ground can trigger the backup detonator.

[0082] Antistatic coating: Conductive material is sprayed onto the surface of the tank to prevent accidental explosion caused by dust friction and static electricity.

[0083] IV. Performance Optimization Directions

[0084] Through wind tunnel experiments and live-fire tests, this fire extinguishing bomb has demonstrated significant advantages:

[0085] Diffusion efficiency: In simulated fire scenarios, the dust coverage area is significantly improved, and the fire extinguishing time is greatly shortened.

[0086] Adaptability: In complex wind field environments, landing point deviation is effectively controlled through dynamic compensation of micro blades.

[0087] Compatibility: It is compatible with a variety of mainstream drone platforms. After being mounted, the flight endurance decreases within a reasonable range, meeting the needs of long-duration missions.
