Description

Technical Field

[0001] This invention relates to the field of forest fire fighting equipment, specifically to a forest fire extinguishing projectile launching system. Background Technology

[0002] The use of aircraft to fight forest fires is becoming increasingly common. In China, the most frequently used aircraft models are the Mi-171, K-32, and Mi-26 helicopters. Current methods include using aircraft to carry water buckets for spraying or drones to drop single or double fire extinguishing bombs. Using aircraft to spray water has limited efficiency, with the aircraft's flight costs accounting for the majority of the cost. Furthermore, an aircraft can only carry one bucket at a time, and the bucket's capacity is limited, allowing spraying only a short distance across the fire area. Drones carrying single or double fire extinguishing bombs represent the latest solution, but one or two bombs can only target point targets and cannot suppress an entire fire line. Drones also have limited payload capacity and cannot carry a large number of fire extinguishing bombs. Even if multiple bombs are carried, they cannot be dropped sequentially along the fire line, a capability current drone control systems cannot achieve. Moreover, even with intelligent identification, there is a high risk of accidental bomb drops, rendering them impractical. The current multi-aircraft formation launch scheme can use a larger number of drones to simultaneously drop multiple fire extinguishing shells. However, the launch efficiency of multiple drones is very low, and they can only strike one fire point at a time. More importantly, multiple aircraft formations are prone to flight path conflicts, disrupting air traffic control. Moreover, forest fires often consist of one or more fire lines, and existing aerial firefighting schemes are not very effective. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a forest fire extinguishing bomb launch system that can be mounted on an aircraft. It can launch multiple fire extinguishing bombs in a linear sequence along the position and length of the fire line to achieve targeted linear fire extinguishing and maximize the fire extinguishing efficiency of medium and large aircraft.

[0004] The objective of this invention is achieved through the following technical measures:

[0005] A forest fire extinguishing grenade launching system, characterized in that it includes a launch handheld device and a fire extinguishing grenade launching device. The fire extinguishing grenade launching device includes a launch controller, a battery, and a fire extinguishing grenade magazine. The fire extinguishing grenade magazine includes a magazine frame, side guards, and impact-resistant legs. The side guards are arranged around the outer perimeter of the magazine frame. The impact-resistant legs are installed at the lower part of the magazine frame and extend downward to below the height of the fire extinguishing grenade. The magazine frame includes staggered longitudinal and transverse support beams at the top. The magazine frame is equipped with several grenade launching devices for mounting fire extinguishing grenade. Each grenade launching device is equipped with an information interaction socket for inserting the safety lead wire of the fire extinguishing grenade. The launch handheld device is wirelessly connected to the launch controller. After receiving the launch command from the launch handheld device, the launch controller injects a delayed ignition signal into each fire extinguishing grenade in sequence and opens the grenade launching device of that fire extinguishing grenade to launch the fire extinguishing grenade in sequence. After receiving the stop command from the launch handheld device, the launch controller stops launching the fire extinguishing grenade.

[0006] As a preferred embodiment, the launch handheld device includes a handheld device host and handheld device software installed in the handheld device host. The handheld device software sets the launch sequence and launch interval of the fire extinguishing projectiles and sends them to the launch controller for execution.

[0007] As a preferred embodiment, the launch controller includes a launch controller host and launch controller software installed within the launch controller host. The handheld device software interacts with the launch controller software to exchange information on the fire extinguishing grenade mounting and launch commands. The launch controller software initiates a control request to a nearby handheld device via the LoRa communication protocol.

[0008] As a preferred embodiment, a reinforced protective frame is provided around the inner side of the side guard plate. The reinforced protective frame includes at least an upper reinforced protective frame and a lower reinforced protective frame, which are respectively fixedly installed on the upper and lower edges of the side guard plate.

[0009] As a preferred option, the distance between two adjacent projectile launching devices is equal to the diameter of the fire extinguishing projectile.

[0010] As a preferred embodiment, the fire extinguishing grenade launcher has a boat-shaped structure with a triangular front and a square rear, and is equipped with three or four lifting hooks on its upper part. The boat-shaped fire extinguishing grenade compartment reduces wind resistance, which is beneficial for aircraft flight and reduces drag. The fire extinguishing grenade compartment is made of aerospace-grade aluminum or carbon fiber, and the lightweight material increases the load capacity of the fire extinguishing grenades. The launch controller main unit and battery compartment are located at the stern. The battery is installed before the fire extinguishing grenade launcher is mounted on the aircraft to prevent accidental triggering, improve safety, and ensure that the battery will not be damaged during long-term storage.

[0011] As a preferred embodiment, the lifting hook attachment point on the upper part of the fire extinguishing grenade launcher is correspondingly set with the anti-collision support leg on the lower part. The anti-collision support leg can be inserted into the lifting hook attachment point, so that the fire extinguishing grenade launcher can be stacked in multiple layers.

[0012] As a preferred embodiment, the fire extinguishing grenade launcher is equipped with landing pads on both sides to prevent structural damage when the fire extinguishing grenade launcher is placed on its side.

[0013] As a preferred embodiment, the projectile launching device includes a mounting base, a projectile hook, a locking mechanism, a release mechanism, and a position detection component. The locking mechanism is connected to the projectile hook by a return spring. The projectile hook has two detection protrusions. The position detection component includes a locking position detection component and a release position detection component. The locking position detection component and the release position detection component detect the positions of the two detection protrusions on the projectile hook in the locked state and the released state, respectively, and send the detection information to the launch controller. The launch controller controls the release mechanism to unlock the locking mechanism, causing the projectile hook to open and release the fire extinguishing projectile.

[0014] As a preferred embodiment, the release mechanism consists of a release motor, a screw, and a lever. The release motor drives the screw to rotate via a gear set, and the lever is screwed onto the screw and pushes the locking mechanism to unlock and the spring hook to open.

[0015] The cartridge hook is connected to a pull rod, and the end of the pull rod away from the cartridge hook is in contact with a lever. When the release mechanism is activated, the lever sequentially moves the locking mechanism to unlock and the pull rod to pull the cartridge hook open.

[0016] The contact point between the bullet hook and the fire extinguishing bullet is at its lowest point when the fire extinguishing bullet is attached, and during the unlocking process, the contact surface between the bullet hook and the fire extinguishing bullet is an inclined surface facing the ground.

[0017] Traditional fire extinguishing bombs are typically carried by drones, which have limited payload capacity and relatively small bomb size and weight. Their bomb-laying and deployment devices rely solely on return springs for reliable loading and release, and bombs are generally loaded only upon arrival at the fire scene, thus placing no demands on safety or reliability during transport. This application, however, utilizes a large carrier, significantly increasing the number of bombs that can be carried at once and the payload capacity. This allows for a substantial increase in the size and weight of the fire extinguishing bombs, improving the extinguishing area per bomb and significantly increasing the bomb quantity and extinguishing area per flight, overcoming the drawback of aircraft-based fire extinguishing systems being aesthetically pleasing but ineffective. Furthermore, this application employs an integrated fire extinguishing bomb storage system, with all bombs directly mounted within multiple fire extinguishing bomb launchers. These launchers are stacked for storage and transport, enabling the rapid delivery of a sufficient quantity of fire extinguishing bombs to the fire scene for efficient deployment. This requires that the loaded fire extinguishing bombs be highly reliable during storage and transportation. Not only must the loading be reliable, but the release must also be reliable. Therefore, the release mechanism of this application has made several improvements. The active pulling of the hook by the lever ensures that the hook opens reliably. The slight opening of the hook allows the weight of the fire extinguishing bomb to be loaded onto the inclined contact surface of the hook. The weight of the fire extinguishing bomb becomes the driving force to accelerate and ensure that the hook opens fully and quickly. Therefore, this application ensures that the hook opens fully, reliably and quickly by the combined force of the return spring, the pulling force of the release mechanism on the lever, and the downward opening force formed by the weight of the fire extinguishing bomb.

[0018] As a preferred embodiment, the fire extinguishing bomb includes a shell, an explosive core, a fire extinguishing agent, and an detonation control module. The upper end of the shell is provided with a lug. The explosive core and the fire extinguishing agent are disposed inside the shell. An electronic detonator is installed inside the explosive core. The detonation control module is electrically connected to the electronic detonator inside the explosive core. The detonation control module receives and executes a delayed detonation command from the launch controller.

[0019] As a preferred embodiment, the fire extinguishing bomb is a specialized forest fire extinguishing bomb designed for forest fires spreading along a fire line. It is sequentially launched using the fire extinguishing bomb launcher described in this application, with a time-delay fuse set according to the flight altitude, detonating after a delay upon reaching the fire line. The extinguishing agent in the fire extinguishing bomb is either a dry powder extinguishing agent or a water-based extinguishing agent.

[0020] As a preferred embodiment, the detonation control module includes a safety lead, which is inserted into an information interaction socket to receive a delayed detonation signal. After disconnecting from the information interaction socket and confirming launch, the detonation control module begins a delay timer. After the safety lead is connected to the interface on the launcher, the detonation control module establishes a connection with the launch controller.

[0021] As a preferred embodiment, the upper part of the shell is provided with a flying wing, which is installed on the upper part of the shell by a hinge and opens due to wind resistance during descent, causing the fire extinguishing bomb to rotate during the descent.

[0022] The fire extinguishing bomb in this application is a forest-specific fire extinguishing bomb. After release, the safety fuse is pulled away by gravity, and the flying wings open due to wind resistance, causing the fire extinguishing bomb to enter a horizontal rotation state. The explosive core is precisely detonated with a delay by the detonation control module, releasing the fire extinguishing agent. If the detonation module receives a detonation command but detects that the safety fuse has not been pulled away, it will not execute the detonation command.

[0023] The casing of a fire extinguishing grenade is generally manufactured using PE injection molding. The casing is cylindrical in the middle and warhead-shaped at the bottom. A circular opening with threads on the inner side is located at the center of the semi-circular lower end of the casing, through which the explosive core is installed. A lug is located at the top of the casing, serving as both a handle for handling and a mounting lug on the launcher. An internally threaded hole is located off-center at the top of the casing for loading the explosive. A small hole at the center of the top of the casing is for threading the safety control lead. Two winglets are located on either side of the casing, their upper ends hinged to the casing and hanging down naturally, concealed in corresponding grooves within the casing.

[0024] The method of using the above-mentioned forest fire extinguishing grenade launching system includes the following steps:

[0025] S1. The launch controller of the fire extinguishing grenade launcher is equipped with a battery and powered on. After the launch controller software runs, it detects the lower electronic detonator and grenade throwing device, and initiates a control request to the nearby handheld device through the LoRa communication protocol.

[0026] S2. The aircraft is equipped with a fire extinguishing bomb launcher. The handheld host is turned on, the bombing system handheld software is run, the communication port is opened, and it waits to receive the active registration information from the launch controller.

[0027] S3. After receiving the active registration information from the launch controller, the bombing system handheld software prompts for confirmation of the control relationship. After the control relationship is established, the launch controller software waits to receive handheld commands and controls the electronic detonator and bomb-loading device.

[0028] S4. After the bombing system handheld software confirms the control relationship, it displays the remaining ammunition, ammunition capacity, launch preparation button, launch button, stop button, launch handheld battery level, and launch controller battery level. The launch button cannot be triggered before the launch preparation button is operated.

[0029] S5. The duration of the delayed detonation can be set via the handheld software, and the detonation can be triggered by clicking the launch button;

[0030] S6. After receiving the launch command and delayed detonation information, the launch controller transmits the delayed detonation information to the fire extinguishing bombs and launches the fire extinguishing bombs in sequence.

[0031] S7. When the handheld device software clicks the stop button, the transmitter controller receives the stop command and stops transmitting.

[0032] Due to the adoption of the above technical solution, the advantages of the present invention compared with the prior art are as follows: The present invention discloses a forest fire extinguishing bomb launcher, which adopts a large ship-shaped fire extinguishing bomb launcher that can carry a large number of fire extinguishing bombs at one time, making full use of the advantage of the large carrying capacity of aircraft. At the same time, the fire extinguishing bomb launcher can release fire extinguishing bombs in a set sequence, so that the fire extinguishing bombs detonate with a delay, and can accurately distribute the fire extinguishing bombs along the fire line to form an efficient fire extinguishing zone, achieving targeted linear fire extinguishing along the fire line, so as to maximize the fire extinguishing efficiency of medium and large aircraft.

[0033] This invention fills the gap in the use of fire extinguishing agents, especially dry powder fire extinguishing agents, for aerial release from medium and large aircraft for forest fire fighting. It enables aerial-launched fire extinguishing bombs to move from being merely capable of extinguishing fires but with questionable efficiency and practicality to playing an important, even primary, role in actual combat.

[0034] This application uses fire extinguishing bombs that are thrown in batches along the fire line with dry powder or water-based extinguishing agents. The fire extinguishing effect and fire extinguishing range are much greater than water and significantly better than bucket water spraying for fire extinguishing.

[0035] Compared with existing fire extinguishing projectile launching systems, this application can fire single shots or multiple shots in succession, which can not only extinguish fire points and fire lines, but also form firebreaks, allowing for more fire extinguishing strategies.

[0036] Compared with existing fire extinguishing bombs, the special forest fire extinguishing bomb mounted on the fire extinguishing bomb launcher of this application has flying wings that make the fire extinguishing bomb rotate rapidly, which not only makes the fire extinguishing bomb fall and fly more stably, but also increases the uniformity of the fire extinguishing agent dispersion after the fire extinguishing bomb explodes.

[0047] Example 1: As shown in the attached document Figures 1 to 4 As shown, the forest fire extinguishing grenade launching system includes a launching handheld device and a fire extinguishing grenade launcher. The fire extinguishing grenade launcher includes a launching controller, a battery, and a fire extinguishing grenade magazine. The fire extinguishing grenade magazine 1 includes a magazine frame 11, side guards 12, and impact-resistant legs 13. The side guards 12 are arranged around the outer perimeter of the magazine frame 11. The impact-resistant legs 13 are installed at the lower part of the magazine frame 11 and extend downward to below the height of the fire extinguishing grenade 2. The magazine frame 11 includes staggered longitudinal support beams 111 and transverse support beams 112 at the top. The ammunition magazine 11 contains several ammunition launching devices 3 for mounting fire extinguishing bombs 2. Each ammunition launching device 3 is equipped with an information interaction socket for connecting the safety lead of the fire extinguishing bomb. The launch handheld device is wirelessly connected to the launch controller. After receiving a launch command from the launch handheld device, the launch controller sequentially injects a delayed ignition signal into each fire extinguishing bomb and opens the ammunition launching device of that fire extinguishing bomb to launch it in sequence. After receiving a stop command from the launch handheld device, the launch controller stops launching fire extinguishing bombs. The launch controller, battery, and information interaction socket are not shown in the attached drawings. The shape of the launch controller can be customized as needed. The battery is a commercially available product, and the information interaction socket is existing technology and will not be described in detail.

[0048] In this embodiment, the launch handheld device includes a handheld device host and handheld device software installed in the handheld device host. The handheld device software sets the launch sequence and launch interval of the fire extinguishing bombs 2 and sends them to the launch controller for execution.

[0049] The launch controller includes a launch controller host and launch controller software installed within the launch controller host. The handheld device software interacts with the launch controller software to exchange information on the fire extinguishing grenade mounting and launch commands. The launch controller software initiates a control request to a nearby handheld device via the LoRa communication protocol.

[0050] Handheld devices are commonly used for remote operation. The communication software can be written according to different operating system programming languages ​​as needed. These are things that software engineers can implement based on existing technology and do not require further description.

[0051] As attached Figure 4 As shown, a reinforced protective frame 14 is provided around the inner side of the side guard plate 12. The reinforced protective frame 14 includes at least an upper reinforced protective frame 141 and a lower reinforced protective frame 142. The upper reinforced protective frame 141 and the lower reinforced protective frame 142 are respectively fixedly installed on the upper edge and the lower edge of the side guard plate 12.

[0052] The distance between two adjacent projectile launching devices 3 is equal to the diameter of the fire extinguishing projectile 2.

[0053] As attached Figure 1 and 2 As shown, the fire extinguishing grenade launcher has a boat-shaped structure with a triangular front and a square rear. The upper part of the launcher has three or four lifting hook attachment points 4. The boat-shaped fire extinguishing grenade compartment 1 has lower wind resistance, which is beneficial for aircraft flight and reduces drag. The fire extinguishing grenade compartment 1 is made of aerospace-grade aluminum or carbon fiber materials; the lightweight material increases the load capacity of the fire extinguishing grenades 2. The launch controller main unit compartment and battery compartment are located at the stern. The battery is installed before the fire extinguishing grenade launcher is mounted on the aircraft to ensure that it will not be accidentally triggered, improve safety, and ensure that the battery will not be damaged during long-term storage.

[0054] The lifting hook attachment point 4 on the upper part of the fire extinguishing grenade launcher is correspondingly set with the anti-collision support leg 13 on the lower part. The anti-collision support leg 13 can be inserted into the lifting hook attachment point 4, so that the fire extinguishing grenade launcher can be stacked in multiple layers.

[0055] The fire extinguishing grenade launcher is equipped with landing pads 5 on both sides to prevent structural damage when the fire extinguishing grenade launcher is placed on its side.

[0056] As attached Figures 6 to 9 As shown, the projectile launching device 3 includes a mounting base 31, a projectile hook 32, a locking mechanism 33, a release mechanism 34, and a position detection component 35. The locking mechanism 33 and the projectile hook 32 are connected by a return spring 36. The projectile hook 32 is provided with two detection protrusions 321. The position detection component 35 includes a locking position detection component and a release position detection component. The locking position detection component and the release position detection component respectively detect the position of the two detection protrusions 321 on the projectile hook 32 in the locked state and the released state, and send the detection information to the launch controller. The launch controller controls the release mechanism 34 to unlock the locking mechanism so that the projectile hook opens and releases the fire extinguishing projectile 2.

[0057] As attached Figure 8 and 9As shown, the release mechanism 34 consists of a release motor 341, a screw 342, and a lever 343. The release motor 341 drives the screw 342 to rotate through a gear set 344. The lever 343 is screwed onto the screw 342 and pushes the locking mechanism 33 to unlock and the spring hook 32 to open.

[0058] The cartridge hook 32 is connected to a pull rod 322. The end of the pull rod 322 away from the cartridge hook 32 is in contact with the lever 343. When the release mechanism 34 is activated, the lever 343 sequentially moves the locking mechanism 33 to unlock and the pull rod 322 to pull the cartridge hook 32 open.

[0059] When the fire extinguishing bomb 2 is mounted, the contact point between the hook 32 and the lug 21 of the fire extinguishing bomb 2 is at its lowest point. During the unlocking process, the contact surface between the hook 32 and the fire extinguishing bomb 2 is an inclined surface facing the ground.

[0060] Traditional fire extinguishing bombs are typically carried by drones, which have limited payload capacity and relatively small bomb size and weight. Their bomb-laying and deployment devices rely solely on return springs for reliable loading and release, and bombs are generally loaded only upon arrival at the fire scene, thus placing no demands on safety or reliability during transport. This application, however, utilizes a large carrier, significantly increasing the number of bombs that can be carried at once and the payload capacity. This allows for a substantial increase in the size and weight of the fire extinguishing bombs, improving the extinguishing area per bomb and significantly increasing the bomb quantity and extinguishing area per flight, overcoming the drawback of aircraft-based fire extinguishing systems being aesthetically pleasing but ineffective. Furthermore, this application employs an integrated fire extinguishing bomb storage system, with all bombs directly mounted within multiple fire extinguishing bomb launchers. These launchers are stacked for storage and transport, enabling the rapid delivery of a sufficient quantity of fire extinguishing bombs to the fire scene for efficient deployment. This requires that the loaded fire extinguishing bombs be highly reliable during storage and transportation. Not only must the loading be reliable, but the release must also be reliable. Therefore, the release mechanism of this application has made several improvements. The active pulling of the hook by the lever ensures that the hook opens reliably. The slight opening of the hook allows the weight of the fire extinguishing bomb to be loaded onto the inclined contact surface of the hook. The weight of the fire extinguishing bomb becomes the driving force to accelerate and ensure that the hook opens fully and quickly. Therefore, this application ensures that the hook opens fully, reliably and quickly by the combined force of the return spring, the pulling force of the release mechanism on the lever, and the downward opening force formed by the weight of the fire extinguishing bomb.

[0061] As attached Figure 5 As shown, the fire extinguishing bomb 2 includes a shell, an explosive core, a fire extinguishing agent, and an detonation control module. The upper end of the shell is provided with a lug 21. The explosive core and the fire extinguishing agent are disposed inside the shell. An electronic detonator is installed inside the explosive core. The detonation control module is electrically connected to the electronic detonator inside the explosive core. The detonation control module receives and executes the delayed detonation command from the launch controller.

[0062] The fire extinguishing bomb 2 is a specialized forest fire extinguishing bomb designed for situations where forest fires spread along a fire line. It is launched sequentially using the fire extinguishing bomb 2 launcher described in this application. The time-delay fuse is set with a specific delay time based on the flight altitude, detonating after a delay upon reaching the fire line. The extinguishing agent in the fire extinguishing bomb 2 is either a dry powder extinguishing agent or a water-based extinguishing agent.

[0063] The detonation control module includes a safety lead, which is inserted into an information interaction socket to receive a delayed detonation signal. After disconnecting from the information interaction socket and confirming launch, the detonation control module begins a delay timer. After the safety lead is connected to the interface on the launcher, the detonation control module establishes a connection with the launch controller.

[0064] The upper part of the shell is provided with a flying wing, which is installed on the upper part of the shell by a hinge and opens by wind resistance during descent, causing the fire extinguishing bomb to rotate during the descent.
