Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a lifting device for a fire-fighting projection cannon. Background Art

[0002] Fire monitor is a highly efficient fire extinguishing equipment that can spray fire extinguishing agents (such as water, foam mixture or dry powder, etc.) to the fire scene at a very high speed, forming a powerful jet, thereby quickly reducing the fire, controlling the fire source, and ultimately extinguishing the fire.

[0003] In the utility model patent with the announcement number CN215136280U, a large-flow mobile remote-controlled fire cannon fire extinguishing assembly is disclosed, including a pickup truck mobile carrier, a water collector and a fire cannon, the water collector is provided with several fire extinguishing medium inlets of different specifications and a fire extinguishing medium outlet, and is fixed on the pickup truck mobile carrier as a whole and can move therewith; the fire cannon is sealed and connected to the fire extinguishing medium outlet of the water collector and placed together on the pickup truck mobile carrier; the fire cannon includes a gun body, a gun head, a control motor and a horizontal pitch and rotation mechanism connected to the control motor and the gun body, the gun body is a large rotating structure, its head end is sealed and connected to the gun head, and its tail end is sealed and connected to the fire extinguishing medium outlet of the water collector, the fire cannon controls the horizontal pitch and rotation mechanism through the control motor to adjust the spray angle and direction of its gun head.

[0004] When handling serious fires, this large-flow mobile remote-controlled fire cannon fire extinguishing component first drives the pickup truck mobile carrier to the fire scene quickly to extinguish the fire, selects the best fire extinguishing position to park, uses a fire hose to connect the water inlet of the water collector and the water outlet of the rear-field fire truck water supply pipeline, operates the rear-field fire truck to supply water to the front-field fire extinguishing component to the rated working pressure, and controls the horizontal pitch and rotation mechanism through the control motor to adjust the spray angle and direction of the cannon head to the best fire extinguishing position for accurate and rapid fire extinguishing.

[0005] However, during application testing, it was discovered that because the fire extinguishing unit is mounted on a pickup truck, it is only suitable for smooth surfaces and cannot be used in mountainous areas, on slopes, or on soft ground, thus limiting its applicability. Furthermore, its limited location also affects the accuracy of the fire extinguishing bomb's launch, limiting its application range.

[0006] Furthermore, loading the fire extinguisher bombs is extremely inconvenient, making consistent and efficient reloading difficult. Furthermore, the fire extinguisher bombs are prone to scratches as they fall, which can affect the structure of the bombs before they are even fired. During firing, the gun barrel structure and the design of the chuck rollers cause not only structural changes but also displacement of the pickup truck. This cumbersome manual adjustment of the gun barrel position not only affects the consistency of the fire extinguisher bomb firing but also significantly reduces the accuracy of the bomb's landing position, hindering the firefighting process.

[0007] In addition, in this case, the position adjustment of the gun body depends on the position of the pickup truck. Therefore, the position of the gun body can only be roughly adjusted and cannot be precisely adjusted, which further reduces the accuracy and applicability of the projectile's projection position.

[0008] Due to the gun's structure, the projectile is significantly affected by airflow during launch, making it prone to rotation or tilt during flight, making it difficult to land accurately along the intended path. Consequently, the combination of these factors makes the projectile's actual landing position relative to the target fire location unpredictable, creating technical obstacles in firefighting efforts.

[0009] Therefore, in view of the problems existing in the current gun machine, such as poor accuracy in the projection direction of fire extinguishing bombs, unstable projection range of fire extinguishing bombs, easy deviation and shaking of the gun body, difficulty in efficiently extinguishing the fire point, and poor adaptability to the environment, a more reasonable technical solution is needed to solve the problems existing in the existing technology. Utility Model Content

[0010] The purpose of the utility model is to provide a lifting device for a fire-fighting projectile gun machine, so as to solve the technical problem in the background art that the projectile direction of the gun machine is difficult to be accurately adjusted.

[0011] In order to achieve the above-mentioned object, the present invention provides a lifting device for a fire-fighting projectile cannon, comprising:

[0012] a sector gear, the axis of which is rotatably connected to the machine body, and a portion of which, away from the axis, is connected to the gun carriage;

[0013] a driving wheel having a tooth shape adapted to the sector gear; and

[0014] The first driver is fixedly arranged on the machine body, and the driving wheel is coaxially arranged on the output shaft of the first driver, and the driving wheel is meshed with the sector gear.

[0015] Optionally, the sector gears are provided in two groups and are spaced apart, and the driving wheels are provided in two groups that mesh with the sector gears one by one.

[0016] Optionally, the two sector gears are both provided on the connecting rod shaft, and both ends of the connecting rod shaft are connected to the machine body via a third bearing.

[0017] Optionally, the lifting device further includes a reinforcing rod, which is arranged between the two sector gears, and two ends of the reinforcing rod are respectively fixedly connected to the two sector gears.

[0018] Optionally, a weight-reducing groove is provided on the sector gear.

[0019] Optionally, the width of the weight-reducing groove gradually increases in a direction away from the axis of the sector gear.

[0020] Optionally, the axial tooth thickness of the driving wheel is greater than the axial tooth thickness of the sector gear.

[0021] Optionally, the first driver includes a motor and a reducer, the output shaft of the motor is connected to the reducer, and the output shaft of the reducer is connected to the driving wheel.

[0022] With this technical solution, when the gun mount's angle and height need to be adjusted, the first actuator activates, rotating the driving wheel. This rotation in turn rotates the sector gear. Since the sector gear is connected to the gun mount, the gun mount moves accordingly. By controlling the output speed and direction of the first actuator, the gun mount's angle and height can be precisely adjusted, enabling accurate aiming and delivery of the gun barrel. This lifting device also features a compact structure, high transmission efficiency, a wide adjustment range, and high precision.

[0023] Other features and advantages of the present invention will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0045] According to a specific embodiment of the present disclosure, a fire-fighting projection cannon is provided, wherein: Figures 1 to 17 One specific implementation method is shown.

[0046] See Figures 1 to 17As shown, the fire-fighting projection gun includes: a body 1; a gun barrel 2, which has a bore adapted for a fire-extinguishing bomb 6; the gun barrel 2 is movably connected to a gun mount 111, and the gun mount 111 is connected to the body 1; a pneumatic device 3, provided on the body 1, for delivering high-pressure gas; a bullet feeding device 4, provided on the body 1, for guiding the fire-extinguishing bombs 6 one by one; and a material distribution device, provided with an arcuate groove 511 for limiting the position of the individual fire-extinguishing bombs 6, the axis of the arcuate groove 511 being parallel to the axis of the gun barrel 2; one end of the material distribution device is connected to the bullet feeding device 4 to receive the fire-extinguishing bombs 6. The fire extinguishing bomb 6 is guided out from the ammunition feeding device 4; the other end of the material distributing device is connected to the pneumatic device 3; the material distributing device also includes a pushing member 55, the fixed end of the pushing member 55 is connected to the gun mount 111, and the telescopic end thereof is connected to the gun barrel 2, the pushing member 55 is used to push the gun barrel 2 to move along the arc groove 511, and insert the fire extinguishing bomb 6 on the arc groove 511 into the bore of the gun barrel 2; wherein, when the fire extinguishing bomb 6 is inserted into the gun barrel 2, the gun barrel 2 is connected to the pneumatic device 3; the pneumatic device 3 delivers high-pressure gas to eject the fire extinguishing bomb 6 from the boring of the gun barrel 2.

[0047] The main body 1 serves as the foundational structure of the entire fire-fighting projectile gun, facilitating the direct or indirect installation of other components, such as the barrel 2, pneumatic device 3, ammunition feeder 4, and material distributor. The gun carriage 111, a support structure for the barrel 2, is connected to the main body 1, providing stable support. The barrel 2 has a bore suitable for receiving and firing a fire-extinguishing projectile 6. The pneumatic device 3 is mounted on the main body 1 to deliver high-pressure gas.

[0048] The feed mechanism 4 is mounted on the gun body 1 and is used to dispense the fire-extinguishing bombs 6 one by one. The feed mechanism, through the design of the arcuate slots 511, precisely defines the position of the fire-extinguishing bombs 6, ensuring their accurate delivery into the bore of the barrel 2. The pneumatic device 3 enables the gun to deliver high-pressure gas, ejecting the fire-extinguishing bombs 6 from the barrel 2 with great speed and force. This high-pressure launch capability enables the fire-extinguishing bombs 6 to be launched over long distances, thereby extinguishing distant fires.

[0049] The operating principle of this fire-fighting projectile cannon is as follows: First, the entire fire-fighting projectile cannon is adjusted according to the location of the fire point, so that the barrel 2 is aligned with the fire point. The ammunition feeding device 4 feeds the fire-extinguishing bombs 6 one by one toward the distribution device. After the fire-extinguishing bombs 6 land in the arc-shaped groove 511 of the distribution device, the pusher 55 pushes the barrel 2 toward the pneumatic device 3, thereby inserting the fire-extinguishing bomb 6 into the bore of the barrel 2, that is, loading the fire-extinguishing bomb 6. Once the barrel 2 is in position, the pneumatic device 3 outputs high-pressure gas, which instantly gushes out of the barrel 2 through the impact force of the high-pressure gas, ejecting the fire-extinguishing bomb 6 from the barrel 2, allowing it to be accurately released at the fire point, effectively extinguishing the fire.

[0050] Based on the above technical solution, the firefighting cannon's feeding, dispensing, pushing, and firing steps can be automated or semi-automated, significantly reducing preparation and firing time and improving fire response efficiency. By combining precise targeting of the fire source with high-pressure firing capabilities, the firefighting cannon can quickly deliver fire extinguishing bombs to the fire source and effectively extinguish it, significantly improving firefighting efficiency and effectiveness, and providing strong support for fire response.

[0051] In an embodiment provided in the present disclosure, the gun barrel 2 includes a tube body 21 and a spoiler 22, and the spoiler 22 is sleeved on one end of the tube body 21 and fixedly connected to the tube body 21; wherein the spoiler 22 is conical, and its diameter gradually increases in the direction away from the tube body 21, and a spoiler hole 23 is provided on the spoiler 22, and the spoiler hole 23 extends along the flow direction of the gas and passes through the spoiler 22, one end of the spoiler hole 23 is located on the outer wall of the spoiler 22, and the other end is located on the inner wall of the spoiler 22.

[0052] The spoiler holes 23 on the spoiler cover 22 are designed to guide the high-pressure gas to generate turbulence when passing through, which can improve the flow efficiency of the gas and the stability of the fire extinguishing bomb 6. The spoiler holes 23 extend along the direction of gas flow, which can optimize the flow characteristics of the gas, reduce turbulence and eddy currents of the gas in the barrel 2, and improve the accuracy of the launch.

[0053] The design of the conical spoiler 22 enhances the overall structural stability of the barrel 2, enabling it to withstand the impact of high-pressure gas. Simultaneously, it can also reduce air resistance, enabling the fire extinguishing bomb 6 to obtain a higher speed and a longer range when launched.

[0054] In the present disclosure, the fire extinguishing bomb 6 includes a coaxially arranged warhead 61, a water tank 62, a reagent tank 63, a chip tank 64, and a tail plate 65. The two ends of the water tank 62 are connected to the warhead 61 and the chip tank 64, respectively. That is, the water tank 62 is located between the warhead 61 and the chip tank 64 and is used to store water or other fire extinguishing liquids. The reagent tank 63 is used to store fire extinguishing agents, which can be dry powder, foam, or other types of fire extinguishing agents, and can be selected according to different types of fire sources.

[0055] Specifically, the reagent compartment 63 is connected to the chip compartment 64, which is equipped with a chip 66. The tail plate 65 is connected to the chip compartment 64, so that the chip 66 is communicatively connected to the tail plate 65. This chip 66 can record relevant information about the fire extinguishing bomb 6, such as the production date, shelf life, and batch number. Furthermore, the chip 66 can also communicate with the tail plate 65, allowing the status of the fire extinguishing bomb 6 to be remotely monitored or controlled. The tail plate 65 not only serves as a connection and fixation function, but also transmits data to the chip 66 via a communication connection. This allows the status information of the fire extinguishing bomb 6 to be remotely read or controlled, improving the efficiency and safety of firefighting operations.

[0056] Among them, the tip of the bullet 61 is provided with an overflow hole, and a head plug 67 is sealed and inserted in the overflow hole. The overflow hole is designed to be used for filling liquid. During the filling operation, the liquid is poured from the overflow hole of the bullet 61. As the filling work continues, bubbles or foam are generated on the surface of the liquid due to the oscillation of the liquid. Therefore, after the filling is completed, the filling will continue until the bubbles or foam in the liquid overflow, and finally the head plug 67 is used for press-fitting. This can further reduce the internal gap, which can effectively eliminate bubbles and fill the bullet 61 with liquid, which is beneficial for the fire extinguishing bomb 6 to fly smoothly along the launch trajectory and avoid the flight trajectory being disturbed by the shaking of the liquid inside. In addition, since the head plug 67 is sharp, it has a certain wind-breaking effect, which can help the fire extinguishing bomb 6 to fly smoothly.

[0057] When the fire extinguishing bomb 6 is launched and hits the target, the liquid in the middle water tank 62 will flow out through the overflow hole of the bullet head 61. At the same time, the agent will be released, thereby acting together with the liquid in the middle water tank 62 or alone to achieve a better fire extinguishing effect.

[0058] When the fire extinguishing bomb 6 is launched and impacts the target, the overflow hole in the bullet head 61 opens, allowing the liquid in the intermediate water tank 62 to flow out rapidly. At the same time, the agent is released, which then acts together or independently with the liquid in the intermediate water tank 62 to achieve a better fire extinguishing effect. Through the communication connection between the chip 66 and the tail plate 65, the status information of the fire extinguishing bomb 6 can be remotely monitored and controlled, making the fire extinguishing operation more accurate and efficient.

[0059] In the present disclosure, the material distribution device includes a receiving seat 51, a sealing seat 52, an air storage pipe 54 and a pushing member 55. The receiving seat 51 is provided with an arc-shaped groove 511 for limiting the position of the fire extinguishing bomb 6. The front end of the arc-shaped groove 511 is sealed to the bearing seat 56, and the rear end is sealed to the sealing seat 52.

[0060] One end of the air storage pipe 54 is connected to the pneumatic device 3, and the other end is connected to the sealing seat 52 through a control pipe 57; a control valve 58 is provided on the control pipe 57 to control the on and off of the air flow;

[0061] The moving end of the pushing member 55 is connected to the barrel 2 , and the moving direction of the moving end is parallel to the axial direction of the barrel 2 , so that the barrel 2 can move along the arc groove 511 to approach or move away from the sealing seat 52 .

[0062] The arcuate groove 511 on the receiving seat 51 defines the position of the fire extinguishing bomb 6, ensuring its stable resting and movement during the dispensing process. The design of the arcuate groove 511 allows the fire extinguishing bomb 6 to be accurately guided to its designated position by the left and right feed mechanisms 4. The front end of the arcuate groove 511 is sealed to the bearing seat 56, and the rear end is sealed to the sealing seat 52. This design ensures the tightness of the arcuate groove 511, preventing gas leakage or the fire extinguishing bomb 6 from falling during the dispensing and pushing process.

[0063] One end of the gas storage tube 54 is connected to the pneumatic device 3, and the other end is connected to the sealing seat 52 via a control tube 57. A control valve 58 is provided on the control tube 57 to control the flow of air. When the fire extinguishing bomb 6 is pushed into the bore of the gun barrel 2, the control valve 58 opens, and the high-pressure gas delivered by the pneumatic device 3 enters the sealing seat 52 through the gas storage tube 54 and the control tube 57, thereby propelling the fire extinguishing bomb 6 out of the gun barrel 2.

[0064] The moving end of the pusher 55 is connected to the barrel 2, and its direction of movement is parallel to the axis of the barrel 2. When the pusher 55 moves, it pushes the barrel 2 along the arcuate groove 511, thereby moving it closer to or further away from the sealing seat 52. When the barrel 2 moves to the appropriate position, the fire extinguisher bomb 6 is pushed into the bore of the barrel 2, ready for firing.

[0065] The design of the two feeding devices 4 and the arcuate groove 511 enables efficient, stable, and consistent feeding of the fire-extinguishing bomb 6, which helps reduce waiting time and improve fire-fighting efficiency. The pusher 55 ensures that the barrel 2 can move precisely along the arcuate groove 511, pushing the fire-extinguishing bomb 6 into the bore of the barrel 2, ready for firing. The control valve 58 controls the on / off flow of air, ensuring safety during the firing process and preventing accidents. The entire feeder device has a rational design and a stable structure, capable of reliable operation in various environments and meeting the needs of firefighting.

[0066] In the present disclosure, the ammunition feeding device 4 includes: a positioning plate 41, which is provided with a discharge port for only a single fire extinguishing bomb 6 to pass through, ensuring that only one fire extinguishing bomb 6 can enter the ammunition feeding process through the discharge port at a time, avoiding blockage or confusion that may be caused by multiple fire extinguishing bombs 6 falling at the same time.

[0067] The magazine 42 is used to store fire extinguishing bombs 6; the magazine 42 is movably connected to the positioning plate 41 via a positioning block 46, allowing the position of the magazine 42 on the positioning plate 41 to be fine-tuned, thereby controlling the speed and timing of the fire extinguishing bombs 6 passing through the discharge port. The feed magazine 43 is arranged below the positioning plate 41, and one end of the feed magazine 43 is connected to the discharge port, and the other end is connected to the arc-shaped groove 511 on the feeding device; and a first linear drive member 44, one end of which is connected to the positioning plate 41 and the other end is connected to the magazine 42. The first linear drive member 44 is used to push the magazine 42 toward or away from the discharge port, so that the fire extinguishing bombs 6 can fall into the feed magazine 43 under the action of gravity.

[0068] Specifically, when the ammunition supply bin 43 needs to be replenished with fire extinguisher bombs 6, the first linear actuator 44 pushes the ammunition storage bin 42 toward the discharge port until the ammunition bombs 6 in the ammunition storage bin 42 are aligned with the discharge port, allowing the ammunition bombs 6 to naturally fall into the ammunition supply bin 43 under the action of gravity. When the ammunition supply bin 43 has a sufficient number of fire extinguisher bombs 6 or the ammunition supply needs to be suspended, the first linear actuator 44 moves in the opposite direction, pushing the ammunition storage bin 42 away from the discharge port, and suspending the drop of the fire extinguisher bombs 6. This ensures a stable and continuous supply of fire extinguisher bombs 6.

[0069] In the present disclosure, the fire-fighting projection gun machine further includes a lifting device 8 , one end of which is connected to the machine body 1 , and the other end is connected to the gun carriage 111 to adjust the elevation angle of the gun carriage 111 .

[0070] The pitch angle refers to the angle of the gun barrel 2 or the muzzle relative to the horizontal plane. During firefighting, the pitch angle of the gun carriage 111 needs to be adjusted according to the height, distance and position of the fire source to ensure that the fire extinguishing bomb 6 can accurately shoot at the target.

[0071] Lifting device 8 can be equipped with an electric drive system or a hydraulic drive system. By controlling these drive systems, the lifting height of lifting device 8 can be precisely adjusted, thereby changing the elevation angle of gun carriage 111 and indirectly changing the position of gun barrel 2. When the elevation angle of gun carriage 111 needs to be increased, lifting device 8 will extend or rise, raising gun carriage 111 relative to machine body 1; conversely, when the elevation angle needs to be reduced, lifting device 8 will shorten or descend, lowering gun carriage 111, ensuring that fire extinguishing bomb 6 can accurately reach the target.

[0072] In the present disclosure, the fire-fighting projection cannon also includes a lifting device 9, which is connected to the body 1 through a loading platform; wherein, the lifting device 9 includes at least three supporting mechanisms 91 that can be lifted and lowered in the vertical direction, and the movements of different supporting mechanisms 91 are independent of each other.

[0073] The lifting mechanism 9 is connected to the fire-fighting cannon body 1 via a loading platform. Its primary function is to adjust the horizontal position, height, and stability of the entire device. Each support mechanism 91 can be independently raised and lowered, allowing the angle of the cannon barrel 2 to be adjusted according to different usage environments, thereby aiming at the target location and achieving optimal firefighting results.

[0074] In the embodiment provided in the present disclosure, the fire-fighting projection cannon further includes a positioning device, the fixed end of which is connected to the loading platform, and the movable end is connected to the body 1 to drive the body 1 to rotate along the vertical direction as the rotation center.

[0075] The positioning device, with the vertical axis as its center of rotation, allows the body 1 to rotate 360 degrees, enabling the fire-fighting cannon to cover a wider area. Regardless of the direction of the fire source, the cannon can quickly and accurately adjust its firing angle, thereby improving its ability to respond to different fire source locations. If the fire source location changes, the fire-fighting cannon can also quickly adjust its firing angle using the positioning device, shortening response time and improving firefighting efficiency.

[0076] Fires are often unpredictable in complex environments like high-rise buildings, forests, and large warehouses. Fire projection cannons equipped with a positioning device can quickly locate and extinguish fire sources, minimizing casualties and property losses. Furthermore, this fire projection cannon is highly practical for specialized applications, such as in high-risk areas like offshore oil platforms and nuclear power plants.

[0077] The fire-fighting projection gun machine also includes a controller, which is communicatively connected to the pneumatic device 3, the bullet feeding device 4 and the material distribution device to control the pneumatic device 3, the bullet feeding device 4 and the material distribution device to perform corresponding actions according to a preset program.

[0078] The controller integrates real-time information such as sensor data and fire scene images, combined with pre-set firefighting strategies and operator instructions, to form an intelligent control system. This system enables precise control of firefighting cannons, ensuring rapid and effective firefighting operations at the scene. The controller also records and analyzes data from the firefighting process, providing a reference and basis for subsequent firefighting efforts.

[0079] In this disclosure, the lifting device 8, the elevating device 9, and the positioning device are also communicatively connected to the controller. These devices are primarily used to drive the parts of the gun mechanism that require rapid and precise control, such as the elevation and depression angles of the gun barrel 2, the height of the gun barrel 2, and the horizontal position and posture of the gun barrel 2. The controller sends commands to the pneumatic device 3, causing it to adjust the gun mechanism's posture and angle according to a preset sequence or based on the real-time fire situation, ensuring accurate and effective delivery.

[0080] It should be understood that the term "and / or" appearing in this article is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist at the same time.

[0081] According to a specific embodiment of the present disclosure, a bullet feeding device 4 for a fire-fighting projectile cannon is also provided. Figures 1 to 9 One specific embodiment is shown.

[0082] See Figures 1 to 9 As shown, the ammunition feeding device 4 for the fire-fighting projectile gun includes: a positioning plate 41, which is provided with a discharge port for only a single fire-extinguishing bomb 6 to pass through, ensuring that only one fire-extinguishing bomb 6 can enter the ammunition feeding process through the discharge port at a time, effectively avoiding blockage or confusion that may be caused by multiple fire-extinguishing bombs 6 falling at the same time.

[0083] The magazine 42 is used to store the fire extinguishing bomb 6; the magazine 42 is movably connected to the positioning plate 41 through a positioning block 46, thereby achieving fine adjustment of the position of the magazine 42 on the positioning plate 41, thereby controlling the speed and timing of the fire extinguishing bomb 6 passing through the discharge port.

[0084] The feed chamber 43 is located below the positioning plate 41. One end of the feed chamber 43 is connected to the discharge port, and the other end is connected to the arc-shaped groove 511 on the material distribution device. When the fire extinguishing bomb 6 falls from the discharge port, it will directly enter the feed chamber 43 and enter the arc-shaped groove 511 of the material distribution device through the other end of the feed chamber 43.

[0085] The first linear actuator 44 controls the descent of the fire extinguishing bomb 6 by pushing the magazine 42 toward or away from the discharge port. Specifically, one end of the first linear actuator 44 is connected to the positioning plate 41, and the other end is connected to the magazine 42. The first linear actuator 44 is used to push the magazine 42 toward or away from the discharge port, allowing the fire extinguishing bomb 6 to fall into the feed chamber 43 under the action of gravity. When the feed chamber 43 needs to replenish fire extinguishing bombs 6, the first linear actuator 44 pushes the magazine 42 toward the discharge port, allowing the fire extinguishing bomb 6 to naturally fall into the feed chamber 43 under the action of gravity. When the feed chamber 43 has sufficient fire extinguishing bombs 6 or the supply needs to be suspended, the first linear actuator 44 pushes the magazine 42 away from the discharge port, pausing the descent of the fire extinguishing bomb 6.

[0086] In the initial state, the magazine 42 is located away from the discharge port, ensuring that no fire extinguishing bombs 6 fall. When the fire-fighting projectile gun needs to launch a fire-extinguishing bomb 6, the first linear actuator 44 is activated, pushing the magazine 42 along the screw toward the positioning plate 41 until the fire-extinguishing bombs 6 in the magazine 42 are aligned with the discharge port. Under the action of gravity, the fire-extinguishing bombs 6 fall into the feed magazine 43 through the discharge port. Under the action of gravity or other conveying devices, the fire-extinguishing bombs 6 in the feed magazine 43 fall into the arc-shaped groove 511 of the distribution device. The distribution device guides the fire-extinguishing bombs 6 one by one to the gun barrel 2 for preparation for launch. When the fire-extinguishing bombs 6 are in place or when the supply of bombs needs to be suspended, the first linear actuator 44 is activated in the reverse direction, pushing the magazine 42 away from the discharge port, and suspending the falling of the fire-extinguishing bombs 6. This not only ensures a stable supply of fire-extinguishing bombs 6, but also improves the safety and reliability of the entire fire-fighting projectile gun.

[0087] In an embodiment provided by the present disclosure, a plurality of buffer plates 45 are provided in the ammunition feeding chamber 43 , and the buffer plates 45 are respectively arranged on both side walls of the ammunition feeding chamber 43 .

[0088] The fire extinguishing bomb 6 falls vertically when it falls, and the presence of the buffer plate 45 can effectively slow down the falling speed of the fire extinguishing bomb 6 in the bomb feeding chamber 43, so that the fire extinguishing bomb 6 enters the distributing device in a stable state.

[0089] The fire extinguishing bomb 6 rolls freely in the magazine 43. Based on the setting of the buffer plate 45, the collision between the fire extinguishing bomb 6 and the side wall of the magazine 43 can be reduced, thereby protecting the integrity of the fire extinguishing bomb 6 and effectively reducing the potential energy when falling into the arc groove 511, thereby reducing impact and reducing noise.

[0090] Furthermore, along the height direction of the ammunition supply chamber 43, the buffer plates 45 on the two side walls are staggered, which can provide a more stable and effective buffering effect during the falling process of the fire extinguishing bomb 6, ensuring that the fire extinguishing bomb 6 falls at a stable speed and posture in the ammunition supply chamber 43, avoiding damage to the fire extinguishing bomb 6.

[0091] Specifically, when falling, the buffer plates 45 are staggered on the two side walls, so that the fire extinguishing bomb 6 will be subjected to forces from different directions during the falling process, which can make the fire extinguishing bomb 6 fall in opposite directions. In this way, the fire extinguishing bomb 6 can gradually fall into the arc-shaped groove 511 from the left and right, which can greatly slow down the falling speed of the fire extinguishing bomb 6, reduce potential energy, and reduce vibration and noise.

[0092] In one embodiment provided herein, the contact surface of the buffer plate 45 is configured as a curved surface. Compared to a flat surface, a curved contact surface can better adapt to the shape of the fire extinguishing bomb 6. When the fire extinguishing bomb 6 contacts the buffer plate 45, the curved surface design can provide a more uniform and stable buffering force, thereby more effectively slowing the falling speed of the fire extinguishing bomb 6, reducing its kinetic energy loss, and ensuring that the fire extinguishing bomb 6 can smoothly enter the bomb feed chamber 43 or the feed device.

[0093] Since the arc contact surface can better fit the surface of the fire extinguishing bomb 6, the noise and vibration generated during the collision will be relatively small, which not only helps to improve the working environment quality of the fire-fighting projectile gun machine, but also can extend the service life of the bullet feeding device 4.

[0094] In practical applications, the curved buffer plates 45 can be applied to the side walls of the magazine 43 and other locations where the falling speed of the fire extinguishing bomb 6 needs to be buffered. By properly configuring the number and position of the buffer plates 45, the falling speed of the fire extinguishing bomb 6 can be precisely controlled, ensuring the efficient and stable operation of the fire-fighting projectile gun.

[0095] Specifically, the buffer plate 45 is configured as a rubber plate or a polyurethane plate.

[0096] The rubber sheet is used as the buffer plate 45. Due to its elastic properties, it can provide sufficient cushioning force when the fire extinguishing bomb 6 falls, reducing collisions and vibrations, thereby reducing damage to the fire extinguishing bomb 6. At the same time, due to its good wear resistance, the rubber sheet can maintain stable performance during long-term use, reducing performance degradation due to wear.

[0097] The polyurethane board is used as the buffer board 45. Based on the material properties of the polyurethane board, it has good buffering performance and can effectively reduce the speed and impact of the falling fire extinguishing bomb 6. The polyurethane board has good resistance to chemical corrosion and can maintain stable performance under various environmental conditions.

[0098] In practical applications, rubber sheet or polyurethane sheet can be selected as the material of the buffer sheet 45 according to the specific use environment and requirements. For example, when a higher buffering effect and wear resistance are required, a rubber sheet can be selected; when a stronger corrosion resistance or a longer service life is required, a polyurethane sheet can be selected.

[0099] In one embodiment of the present disclosure, the ammunition storage chamber 42 and the ammunition feed chamber 43 are both tilted so that the axis of the fire extinguishing bomb 6 is parallel to the axis of the barrel 2. This arrangement allows the fire extinguishing bomb 6 to roll or slide along the inclined surface of the chamber as it falls under its own gravity, keeping the axis of the fire extinguishing bomb 6 parallel to the axis of the barrel 2. This ensures that the axis of the fire extinguishing bomb 6 is aligned with the axis of the barrel 2 when the fire extinguishing bomb 6 is pushed or loaded into the barrel 2, thus preventing problems such as deviation or jamming during firing and ensuring smooth loading of the fire extinguishing bomb 6.

[0100] In the present disclosure, a partition is provided in the magazine 42 to separate it into two chambers. Each chamber is sized to allow only the fire extinguishing bombs 6 to be released in the same posture. By dividing the chamber into two chambers, the dimensions of each chamber are precisely designed to ensure that the fire extinguishing bombs 6 therein are released in the same posture, thereby ensuring the efficiency and effectiveness of the fire-fighting projectile cannon.

[0101] The chamber dimensions prevent interference and collision between the fire extinguisher bombs 6 within the magazine 42, reducing the possibility of accidental release. Furthermore, the orderly storage facilitates quick identification and access by the operator. The two independent chambers can store different types of fire extinguisher bombs 6 or spare fire extinguisher bombs 6 to meet varying firefighting needs.

[0102] In addition, based on the arrangement of the magazine 42, different types of fire extinguishing bombs 6 can also be stored in the two chambers respectively so as to be quickly taken out when needed. For example, one chamber can store fire extinguishing bombs 6 for solid combustion, while the other chamber stores fire extinguishing bombs 6 for liquid or gas combustion.

[0103] Certainly, also can be a chamber can deposit the fire extinguishing bomb 6 being used, and another chamber then is used as standby storage. When the fire extinguishing bomb 6 of main chamber is exhausted, can switch to standby chamber rapidly, guarantee the continuous work of fire-fighting projection gun machine.

[0104] The separated chambers facilitate maintenance and management of the fire extinguishing bombs 6. Operators can regularly check the status of the fire extinguishing bombs 6 in each chamber and replace damaged or expired fire extinguishing bombs 6 in time to ensure the reliability and safety of the fire-fighting projectile gun machine.

[0105] In an embodiment provided in the present disclosure, the first linear drive member 44 includes: a nut seat, which is arranged on the body 1, and the nut seat is provided with a threaded hole and a through hole; a screw rod, which is inserted in the threaded hole and rotatably connected to the body 1; a light rod, which is inserted in the through hole, and both ends of the light rod are rotatably connected to the body 1; and a first motor, which is arranged on the positioning plate 41, and its output shaft is transmission-connected to the screw rod to drive the screw rod to rotate.

[0106] The threaded hole allows the screw to be inserted and engage with the threads inside the nut seat. When the screw rotates, the interaction with the threads causes the positioning block 46 to move along the axial direction of the screw. The polished rod improves the stability of the positioning block 46 during linear movement, preventing it from rotating or otherwise moving unexpectedly.

[0107] Specifically, one end of the screw is rotatably connected to the positioning plate 41 via a first bearing, and the other end is connected to the nut seat. The screw serves as a transmission element, and its rotation translates into linear motion of the positioning block 46. A first motor is mounted on the positioning plate 41, with its output shaft drivingly connected to the screw. Rotation of the motor drives the screw, which in turn drives the positioning block 46 along the screw.

[0108] When the position of the magazine 42 needs to be adjusted, the first motor is activated, and its output shaft drives the screw to rotate. This rotation is converted into linear motion by the nut, which in turn drives the positioning block 46. The positioning block 46 moves on the screw, thereby driving the linear movement of the magazine 42 connected to it. The coordination between the screw and positioning block 46, as well as the transmission relationship between the screw and nut, ensures smooth and accurate movement of the magazine 42.

[0109] In an embodiment provided in the present disclosure, the magazine 42 and the first linear drive member 44 are each provided in two groups, and the magazine 42 is respectively provided on both sides of the discharge port; the first linear drive member 44 is correspondingly connected to the magazine 42.

[0110] By providing a magazine 42 on each side of the discharge port, it is ensured that during the firing process of the gun barrel 2, while one magazine 42 is feeding ammunition, the other magazine 42 is already ready with the next fire extinguishing bomb 6, thereby greatly reducing the waiting time for ammunition feeding and improving ammunition feeding efficiency. Since the two magazines 42 feed ammunition alternately, there is almost no interruption in ammunition feeding during the firing process, thereby enhancing the continuity of shooting.

[0111] Each magazine 42 is equipped with an independent first linear drive 44. Even if one first drive 83 fails, the other first drive 83 can still work normally, thereby increasing the reliability of the equipment.

[0112] In an embodiment provided by the present disclosure, a limit switch is provided on the positioning plate 41 , and the limit switch is communicatively connected to the controller and the first linear drive member 44 .

[0113] The limit switch is used to detect whether the magazine 42 reaches a preset limit position. The preset limit position may include the maximum and minimum movement distances of the magazine 42 to ensure that the magazine 42 moves within a safe range.

[0114] The controller is the control hub of the fire-fighting projectile machine, responsible for receiving and processing various signals and controlling the operation of the equipment according to these signals. When the limit switch is triggered, a signal is sent to the controller to inform that the magazine 42 has reached the preset limit position.

[0115] When the controller receives a signal from the limit switch, it sends a command to the first linear actuator 44 to stop moving, change its direction, or reduce its speed. This prevents the magazine 42 from exceeding its safe range of movement, thereby avoiding damage to the equipment or personal injury.

[0116] In actual applications, the placement of limit switches can be adjusted based on specific equipment requirements. For example, a limit switch can be placed at the maximum and minimum travel positions of the magazine 42 to ensure that the magazine 42 does not exceed these positions during movement. Furthermore, additional limit switches can be placed at certain key locations of the magazine 42 to provide more precise position control and protection.

[0117] According to a specific embodiment of the present disclosure, a material distribution device for a fire-fighting projectile cannon is provided, wherein: Figures 1 to 7 as well as Figure 10 One specific embodiment is shown.

[0118] See Figures 1 to 7 as well as Figure 10 As shown, the material distribution device for the fire-fighting projection cannon includes a receiving seat 51, a sealing seat 52, a gas storage pipe 54 and a pushing member 55. The receiving seat 51 is provided with an arc groove 511 for limiting the position of the fire-extinguishing bomb 6 to ensure that the fire-extinguishing bomb 6 does not deviate from the predetermined path during transportation. The front end of the arc groove 511 is sealed to the bearing seat 56, and the rear end is sealed to the sealing seat 52 to ensure that the airflow does not leak during transportation and ensure the gas pressure.

[0119] One end of the air storage tube 54 is connected to the pneumatic device 3, and the other end is connected to the sealing seat 52 via a control tube 57. The control tube 57 is provided with a control valve 58 to control the on / off flow of air. The moving end of the pusher 55 is connected to the barrel 2, and its movement direction is parallel to the axis of the barrel 2, allowing the barrel 2 to move along the arcuate groove 511 to move closer to or away from the sealing seat 52. When the fire extinguishing bomb 6 is pushed near the sealing seat 52, the pusher 55 pushes the barrel 2 along the arcuate groove 511, moving the barrel 2 closer to or away from the sealing seat 52, so that the fire extinguishing bomb 6 can be accurately delivered into the barrel 2.

[0120] When the barrel 2 abuts the sealing seat 52, the fire extinguishing bomb 6 has been successfully pushed into the barrel 2. The control valve 58 is opened, and the pneumatic device 3 provides airflow to the sealing seat 52 through the gas storage pipe 54 and the control pipe 57. The high-pressure gas propels the fire extinguishing bomb 6 out of the chamber, causing it to fly and land at the target location to participate in the fire extinguishing operation. After the fire extinguishing bomb 6 is ejected, the pushing member 55 moves the barrel 2 away from the sealing seat 52 and returns to its initial position, ready for the next delivery.

[0121] The design of the material distribution device makes the delivery process of the fire extinguishing bomb 6 more automated, efficient and safe. By accurately controlling the on-off of the airflow and the movement of the barrel 2, it can be ensured that the fire extinguishing bomb 6 is accurately ejected, providing reliable protection for the shooting of the fire projection gun machine.

[0122] In one embodiment provided by the present disclosure, the pushing member 55 includes a clamp 551 and a linear module 552. The linear module 552 is connected to the barrel 2 through the clamp 551 to push the barrel 2 to move in the arc groove 511. The clamp 551 can fix and connect the barrel 2 and the linear module 552. During assembly, the clamp 551 is tightly wrapped around the outer surface of the barrel 2 to ensure the stability and accuracy of the barrel 2 during movement. In a fire-fighting projectile gun, the linear module 552 is connected to the barrel 2 through the clamp 551. When the linear module 552 is actuated, it pushes the barrel 2 to move in the arc groove 511, thereby realizing automatic loading of the fire-extinguishing bomb 6.

[0123] When the fire extinguisher bomb 6 needs to be loaded from the magazine 42 into the barrel 2, the control system sends a command to the linear module 552. Upon receiving the command, the linear module 552 activates the motor, which, through the cooperation of the guide rail and the positioning block 46, pushes the barrel 2 within the arcuate slot 511. Thanks to the tight connection of the clamp 551, the barrel 2 maintains a stable posture during movement, ensuring that the fire extinguisher bomb 6 enters the barrel 2 accurately. When the barrel 2 moves to the appropriate position, the linear module 552 stops, indicating that the fire extinguisher bomb 6 has been successfully loaded and can be fired.

[0124] It should be noted that the material and structure of the clamp 551 should be strong enough to withstand the force and impact that may be generated when the gun barrel 2 moves.

[0125] The linear module 552 generally includes a motor, a guide rail, a positioning block 46 and a control system, and can achieve precise linear motion.

[0126] In one embodiment provided herein, the bearing seat 56 is provided with a second bearing for sleeved onto the barrel 2. Lubricating oil is provided in the second bearing. The second bearing provides a stable support point for the barrel 2, ensuring that the barrel 2 remains in the correct position during movement and preventing it from shifting or shaking.

[0127] The insertion of the barrel 2 into the second bearing helps reduce resistance during its movement, making it easier for the pusher 55 to push. During the movement of the barrel 2, friction generates a certain amount of heat. The lubricating oil absorbs and dissipates this heat, cooling the barrel 2 and preventing it from overheating. The lubricating oil also forms a protective film on the surface of the barrel 2, preventing it from coming into contact with moisture and oxygen in the environment, thereby reducing the risk of corrosion.

[0128] In addition, the lubricating oil can also form a lubricating film between the barrel 2 and the second bearing, further reducing the friction coefficient, so that the barrel 2 moves more smoothly in the bearing seat 56, so the conveying efficiency of the entire material distribution device will be improved, which helps to speed up the loading speed of the fire extinguishing bomb 6 and improve the response speed of the fire-fighting projection gun.

[0129] In one embodiment provided by the present disclosure, a flexible sealing ring is provided on the sealing seat 52. The main function of the flexible sealing ring is to provide a tight sealing effect to prevent gas from leaking from the gap between the sealing seat 52 and the barrel 2 or other connecting parts.

[0130] Specifically, the sealing ring is made of elastic materials such as rubber, silicone or plastic, which have excellent elasticity and corrosion resistance and can adapt to various working environments and media. In this regard, those skilled in the art can flexibly configure it according to actual needs.

[0131] It should be noted that when the sealing ring is installed, it is completely embedded in the sealing seat 52 and can fit tightly with the end face of the barrel 2, thereby ensuring airtightness.

[0132] In the present disclosure, the inner diameter of the gas outlet on the sealing seat 52 is smaller than the inner diameter of the barrel 2. This creates a pressure differential between the sealing seat 52 and the barrel 2, ensuring that gas can flow out of the barrel 2 more smoothly without causing backflow or leakage. Due to the smaller inner diameter of the gas outlet, the fluid will experience a certain pressure loss when passing through it, but this loss helps to ensure the stability and directionality of the fluid flow within the pipeline, allowing the high-pressure gas to propel the fire extinguishing bomb 6 smoothly toward the target location.

[0133] The inner diameter of the air outlet is smaller than that of the cannon barrel 2, which helps improve fluid mobility and concentration. However, it is important to note that the inner diameter of the air outlet cannot be too small. If the inner diameter of the air outlet is too small, it will cause excessive pressure loss during the passage of the fluid, thereby affecting the spraying capacity and fire-fighting effect of the water monitor. Therefore, during design, the inner diameter of the air outlet should be reasonably determined based on specific usage requirements and environmental conditions.

[0134] In one embodiment provided herein, the gas storage tube 54 is C-shaped. This C-shaped tube 54 utilizes space more efficiently, reducing overall volume and weight. Furthermore, the shape of the tube 54 provides improved structural strength and stability. In certain applications, such as fire suppression systems, the tube 54 must withstand certain pressures. This C-shaped design enhances the tube's pressure resistance and stability, ensuring it is protected from damage during use.

[0135] In one embodiment provided by the present disclosure, the material distributing device further includes a curved plate 59, which is connected to the gas storage pipe 54 and is tilted upward toward the control valve 58. The curved plate 59 can provide a certain degree of covering and protection for the control valve 58, and at the same time, such a configuration also has a certain aesthetic appeal.

[0136] In the present disclosure, a lifting device 8 for a fire-fighting projectile cannon is provided. Figures 4 to 7 One specific implementation method is shown.

[0137] See Figures 4 to 7 As shown, the lifting device 8 for the fire-fighting projection gun includes: a sector gear 81, whose axis is rotatably connected to the body 1, and its part away from the axis is connected to the gun carriage 111. When the sector gear 81 rotates, the gun carriage 111 will also move accordingly, thereby realizing the angle and height adjustment of the gun barrel 2.

[0138] The driving wheel 82 has a tooth profile that matches the sector gear 81, thereby ensuring stable meshing with the sector gear 81 and maintaining a stable transmission effect even under heavy loads or high speeds. The first driver 83 is fixedly mounted on the body 1, and the driving wheel 82 is coaxially mounted on the output shaft of the first driver 83, and the driving wheel 82 meshes with the sector gear 81.

[0139] Through the above technical solution, when the angle and height of the gun carriage 111 need to be adjusted, the first driver 83 is activated to rotate the driving wheel 82, which in turn rotates the sector gear 81. Since the sector gear 81 is connected to the gun carriage 111, the gun carriage 111 also moves accordingly. By controlling the output speed and direction of the first driver 83, the angle and height of the gun carriage 111 can be precisely adjusted, thereby achieving accurate aiming and projection of the gun barrel 2. Furthermore, this lifting device 8 features a compact structure, high transmission efficiency, a large adjustment range, and high accuracy.

[0140] In one embodiment provided herein, the sector gears 81 are provided in two sets, spaced apart from each other, and the driving wheels 82 are provided in two sets, each meshing with the sector gears 81. The coordination of the two sets of sector gears 81 and the driving wheels 82 significantly increases the output torque. While one set of gears is operating, the other can serve as a backup or auxiliary, reducing the risk of system failure due to a single component failure. This ensures greater precision and stability when adjusting the angle and height of the gun barrel 2. This ensures that the firefighting cannon can quickly and accurately locate the source of the fire and effectively extinguish it, particularly in situations involving large fires or emergency situations requiring rapid response.

[0141] In one embodiment provided by the present disclosure, two sector gears 81 are both mounted on a connecting rod shaft 84, and both ends of the connecting rod shaft 84 are connected to the housing 1 via third bearings 87. The sector gears 81 are mounted on the connecting rod shaft 84 and connected to the housing 1 via the connecting rod shaft 84, so that the sector gears 81 can remain stable during rotation and are not prone to deviation or shaking.

[0142] The third bearing 87 can withstand large radial and axial loads, ensuring the stability of the connecting rod shaft 84 when rotating at high speed or bearing large torque, and further enhancing the connection reliability between the connecting rod shaft 84 and the body 1.

[0143] When the first driver 83 rotates the driving wheel 82, it meshes with the sector gear 81, driving the sector gear 81 and the connecting rod shaft 84 to rotate together. Because both ends of the connecting rod shaft 84 are connected to the body 1 via bearings, the sector gear 81 remains stable during rotation. Furthermore, because the axis of the sector gear 81 is horizontally positioned, the rotation of the sector gear 81 drives the gun carriage 111 in pitch and roll, thereby adjusting the angle and height of the gun barrel 2.

[0144] When selecting the third bearing 87, comprehensive consideration should be given to factors such as the diameter, rotational speed, and load bearing capacity of the connecting rod shaft 84. The selected bearing should be able to withstand the various forces and moments generated by the connecting rod shaft 84 during operation. Those skilled in the art can flexibly configure the bearing based on actual needs.

[0145] In an embodiment provided by the present disclosure, the jacking device 8 further includes a reinforcing rod 85 , which is disposed between the two sector gears 81 , and both ends of the reinforcing rod 85 are fixedly connected to the two sector gears 81 .

[0146] The reinforcement rod 85, by connecting the two sector gears 81 at its ends, forms a stable triangular structure that effectively resists external loads and torque, thereby increasing the structural strength of the entire lifting device 8. It also allows the two sector gears 81 to rotate synchronously, ensuring smooth movement of the gun carriage 111. Under heavy loads or long periods of operation, the sector gears 81 may be subjected to significant stress and deformation. The reinforcement rod 85 helps to distribute these stresses and deformations, thereby protecting the sector gears 81 from damage.

[0147] In the present disclosure, the sector gear 81 is provided with a weight-reducing groove 86. This design not only reduces the overall mass of the gear but also lowers its moment of inertia, reducing the driving force required during high-speed rotation or under heavy loads, thereby improving transmission efficiency to a certain extent. Furthermore, the weight-reducing groove 86 optimizes stress distribution within the gear, reducing the effects of stress concentration and thereby improving the gear's fatigue strength and durability.

[0148] Furthermore, the width of the weight-reducing groove 86 gradually increases as it moves away from the axis of the sector gear 81, further reducing the overall weight of the gear while meeting the structural strength requirements. Because the weight-reducing groove 86 reduces the gear's moment of inertia, it reduces unnecessary power consumption during gear rotation. The gradually increasing groove width design allows the weight-reducing groove 86 to generate less air resistance during gear rotation, further reducing power consumption and improving transmission efficiency.

[0149] In addition, this design can also increase the surface area of the gear, thereby increasing the contact area with the surrounding air, which is conducive to the faster dissipation of heat generated by the gear when rotating at high speed, reducing the temperature of the gear and increasing its service life.

[0150] In the present disclosure, the axial tooth thickness of the driving wheel 82 is greater than that of the sector gear 81. This greater axial tooth thickness provides a larger contact area and more stable transmission when meshing with the sector gear 81. This reduces vibration and noise caused by poor meshing, improving the smoothness and reliability of the gear transmission.

[0151] Since the driving wheel 82 has a larger axial tooth thickness, it can withstand a larger load and torque, which can improve the transmission efficiency to a certain extent and reduce the energy loss caused by poor meshing.

[0152] In one embodiment provided herein, the first driver 83 includes a motor and a reducer. The motor's output shaft is connected to the reducer, and the reducer's output shaft is connected to the driving wheel 82. This converts the motor's high-speed, low-torque output into a low-speed, high-torque output, helping to provide sufficient torque to drive the sector gear 81 and the gun carriage 111 for lifting and lowering. The reducer also reduces the impact and vibration caused by the motor directly driving the driving wheel 82.

[0153] When the motor starts, its output shaft rotates the reducer. The reducer converts the motor's high-speed, low-torque output into a low-speed, high-torque output, and through its output shaft, drives the driving wheel 82. Driving wheel 82 meshes with sector gear 81, driving sector gear 81 and connecting rod shaft 84 to rotate together, thereby adjusting the position of gun mount 111.

[0154] According to a specific embodiment of the present disclosure, a lifting device 9 for a fire-fighting projectile cannon is provided. Figures 1-3 as well as Figure 7 and Figure 8 One specific embodiment is shown.

[0155] See Figures 1-3 as well as Figure 7 and Figure 8As shown, the lifting device 9 for a fire-fighting projectile gun includes at least three vertically movable support mechanisms 91. The different support mechanisms 91 move independently of one another, allowing the gun to be supported at multiple points and maintain stability through height adjustment even on uneven surfaces. The support mechanisms 91 include a positioning end and a linear telescopic end. The positioning end is fixedly connected to the loading platform 7, and a footrest 93 is provided at the bottom of the linear telescopic end. The lifting device 9 also includes a crossbeam 92, the ends of which are connected to the positioning ends of different support mechanisms 91, forming a stable frame structure. This not only enhances the stability of the entire lifting device 9 but also prevents relative displacement of the support mechanisms 91 during the lifting process.

[0156] Through the above-described technical solution, by connecting multiple independently adjustable support mechanisms 91 and crossbeams 92, the lifting device 9 can provide stable support on various terrains. Because the different support mechanisms 91 move independently of each other, the height of each support mechanism 91 can be adjusted individually according to the actual terrain conditions to achieve optimal support. This adapts to different terrains and aiming requirements, providing great flexibility and applicability, allowing the firefighting cannon to operate stably on various road surfaces.

[0157] In one embodiment provided herein, the foot 93 is provided with a ball socket; the bottom of the linear telescopic end is provided with a ball head 95 that fits within the socket. The ball head 95 is embedded within the socket. The foot 93 is the portion of the lifting mechanism 9 that contacts the ground and supports the entire mechanism. The ball socket on the foot 93 is typically a groove that occupies two-thirds of a sphere, with the spherical volume of the groove being at least greater than three-fifths of the entire sphere. This allows the ball head 95 to rotate and tilt to a certain degree.

[0158] Since the ball head 95 can rotate and tilt freely in the ball socket, the moment and torque caused by uneven ground can be eliminated, and the balance point can be reached through the cooperation of the ball head 95 and the ball socket, thereby providing a stable support effect, allowing the lifting device 9 to adapt to different terrains and conditions, ensuring that the fire-fighting projection cannon can always remain stable.

[0159] When the lifting device 9 is placed on uneven terrain, the pressure and angle of each support mechanism 91 will also vary due to the changes in the ground height and angle. At this time, the matching design of the ball socket and ball head 95 allows the linear telescopic end to adapt to the actual ground conditions.

[0160] Specifically, the ball head 95 can rotate and tilt within the socket, ensuring that the linear telescopic end always remains perpendicular or nearly perpendicular to the ground, providing stable support for the lifting device 9. This is particularly suitable for firefighting cannons that need to operate in complex terrain and conditions. Whether on rugged mountain roads, muddy wetlands, or uneven urban surfaces, this lifting device 9 can provide stable support for the cannon, ensuring that it can accurately and efficiently perform firefighting tasks.

[0161] In the embodiment provided in the present disclosure, the support mechanism 91 is configured as a hydraulic cylinder, and a foot is provided at the end of the hydraulic cylinder; multiple hydraulic cylinders are respectively connected to a hydraulic station through oil pipes; and the hydraulic station is communicatively connected to a controller.

[0162] Hydraulic cylinders use the pressure of hydraulic oil to generate thrust or pull, thereby controlling their own raising and lowering. Footrests are installed at the ends of the hydraulic cylinders to increase the contact area with the ground, thereby improving the stability of the support. Multiple hydraulic cylinders are connected via oil pipes to a hydraulic station, which is responsible for providing and controlling the pressure and flow of the hydraulic oil. By adjusting the pressure and flow of the hydraulic station, the raising and lowering speed and position of each hydraulic cylinder can be precisely controlled, thereby achieving precise adjustment of the gun machine.

[0163] The controller can adjust the hydraulic station parameters in real time according to preset programs or operator instructions, thereby controlling the lifting and lowering of the hydraulic cylinder. In addition, the controller can also receive feedback signals from sensors, such as the position and pressure of the hydraulic cylinder, to achieve more precise closed-loop control.

[0164] Among them, the footrests are usually made of wear-resistant and non-slip materials to ensure reliable support in various terrains and conditions.

[0165] In the present disclosure, the footrest 93 is constructed of rust-resistant metal. Metal generally possesses high strength and can withstand significant pressure and weight, ensuring the stability of the lifting device 9 under various operating conditions. Furthermore, the metal footrest offers excellent thermal conductivity, allowing it to quickly transfer heat to the surrounding environment, reducing the risk of performance degradation or damage due to high temperatures. This allows the firefighting cannon to effectively adapt to a variety of operating environments, such as humid, rainy, and even highly corrosive environments like the seaside.

[0166] Furthermore, the support mechanisms 91 are arranged in four symmetrical groups; the positioning ends of each support mechanism 91 are fixedly connected to the corners of the loading plate 7. This allows the lifting device 9 to evenly distribute the load when bearing weight, preventing excessive pressure on any one part, which could lead to damage or instability. In emergency situations such as firefighting and rescue operations, the lifting device 9 can quickly and accurately adjust the position and angle of the gun to ensure the smooth progress of the rescue operation.

[0167] In the present disclosure, a pad 94 is provided between the support mechanism 91 and the carrier plate 7. Pad 94 provides a cushioning layer between the support mechanism 91 and the carrier plate 7, reducing direct stress caused by mechanical vibration, impact, or adjustment. This effectively protects the carrier plate 7 and the fire-fighting cannon mounted thereon from damage and excessive wear. Furthermore, pad 94 increases the contact area between the support mechanism 91 and the carrier plate 7, improving stability. Especially on uneven or sloped surfaces, pad 94 ensures stable contact between the support mechanism 91 and the carrier plate 7, preventing slippage or tilting.

[0168] Specifically, the backing plate 94 can be detachably disposed between the support mechanism 91 and the loading plate 7, allowing for adjustment or replacement as needed to accommodate different working environments and requirements. For example, if the height or angle of the fire cannon needs to be adjusted, this can be achieved by adding or reducing the number or thickness of the backing plates 94.

[0169] The pad 94 can be a rubber pad 94, a metal pad 94, or a composite pad 94. The rubber pad 94 offers excellent cushioning and anti-slip properties, making it suitable for applications requiring vibration and impact reduction. The metal pad 94 offers high strength and wear resistance, making it suitable for applications requiring high pressure and friction. The composite pad 94 also offers excellent cushioning, anti-slip, and wear resistance. Those skilled in the art can flexibly select the type of pad 94 based on the application environment.

[0170] According to a specific embodiment of the present disclosure, a positioning device for a fire-fighting projectile cannon is provided, wherein: Figures 4 to 6 One specific embodiment is shown.

[0171] See Figures 4 to 6 As shown, the positioning device for a fire-fighting projectile cannon includes: a worm gear, one end of which is fixedly connected to the body 1, i.e., the rotation center of the body 1 coincides with the axis of the worm gear; the other end of the worm gear is rotatably connected to the loading plate 7; a worm, rotatably mounted on the loading plate 7 and meshing with the worm gear; and a second motor 101, the output shaft of which is drivingly connected to the worm gear. When the second motor 101 drives the worm gear to rotate, the worm gear drives the body 1 to rotate about the axis of the worm gear.

[0172] With the above technical solution, when the second motor 101 is activated and drives the worm, the worm wheel also begins to rotate due to the meshing relationship between the worm and the worm wheel. Because one end of the worm wheel is fixedly connected to the body 1, the rotation of the worm wheel drives the body 1 to rotate together, with the axis of the worm wheel as the center of rotation. This allows the position of devices such as the barrel 2 located on the body 1 to be adjusted. The worm gear mechanism features high transmission accuracy and a large transmission ratio, making the rotation of the body 1 more precise and reliable.

[0173] The positioning device rotates vertically, allowing the body 1 to rotate about the rotational center of the positioning device. This allows the fire-fighting cannon to cover a wider area. This allows the cannon to quickly and accurately adjust its firing angle regardless of the direction of the fire source, thereby improving its ability to respond to different fire source locations. If the location of the fire source changes, the fire-fighting cannon can also quickly adjust its firing angle using the positioning device, shortening response time and improving firefighting efficiency.

[0174] In an embodiment provided in the present disclosure, the positioning device includes a housing 102, which is fixedly connected to the carrier plate 7; the housing 102 is provided with an opening corresponding to the worm, and the worm wheel is arranged in the housing 102 and engages with the worm at the opening.

[0175] Housing 102 is fixedly connected to carrier plate 7, providing a closed environment for the worm gear, protecting it from dust, moisture, and other potential contaminants, thereby extending its service life. Housing 102 is provided with an opening corresponding to the worm. This opening allows the worm to extend from the outside into housing 102 and engage with the worm gear. This not only ensures a smooth transmission relationship between the worm gear and the worm gear, but also enhances the overall appearance of the device. This allows the worm gear to rotate smoothly when driven by the worm gear, thereby driving the fire-fighting cannon mounted on body 1 to rotate.

[0176] In addition, the protective function of the housing 102 can also reduce the external impact or damage to the worm wheel, thereby playing a certain protective role for the worm gear.

[0177] In the present disclosure, the positioning device further includes a fourth bearing 103 adapted to the housing 102. The inner side of the fourth bearing 103 is fixedly connected to the worm gear, and the outer periphery of the fourth bearing 103 is sleeved within the housing 102. The inner side of the fourth bearing 103 is fixedly connected to the worm gear, ensuring smooth and vibration-free rotation of the worm gear, thereby achieving precise control and stable operation of the fire-fighting projectile cannon.

[0178] The outer periphery of the fourth bearing 103 is sleeved in the housing 102 to form a rotating support structure, avoiding direct contact between the worm gear and the housing 102, thereby reducing friction and wear, which not only increases the service life of the positioning device, but also reduces noise and heat generated by friction.

[0179] In order to reduce friction and wear, an appropriate amount of lubricant may be added between the fourth bearing 103 and the worm gear and the housing 102 , thereby improving the operating efficiency of the positioning device and extending its service life.

[0180] In an embodiment provided in the present disclosure, the positioning device includes an angle sensor for detecting the worm gear angle information, and the angle sensor is communicatively connected to a controller, and the controller controls the motion turntable of the second motor 101 accordingly according to the worm gear angle information.

[0181] An angle sensor is mounted on the positioning device to detect the worm gear's rotational angle. This sensor measures the worm gear's rotational angle in real time and converts this information into an electrical signal. The controller receives the electrical signal from the angle sensor and uses it to control the motion of the second motor 101.

[0182] Specifically, as the worm wheel rotates under the drive of the worm, the angle sensor detects the worm wheel's rotational angle in real time and converts this information into an electrical signal. The angle sensor transmits the detected electrical signal to the controller. After receiving the signal from the angle sensor, the controller generates corresponding control instructions based on the worm wheel's current rotational angle and a preset target rotational angle (if necessary). The controller then sends these instructions to the second motor 101 to control the motor's motion. If the worm wheel has rotated past the predetermined angle, the controller may issue a command to stop the motor; if the worm wheel has not yet reached the predetermined angle, the controller will continue to issue a command to the motor. Through real-time monitoring by the angle sensor and precise control by the controller, the positioning device can achieve precise control of the worm wheel's rotational angle, thereby improving the positioning accuracy and firing accuracy of the firefighting projectile cannon.

[0183] Furthermore, the body 1 is connected to the worm gear through a mounting plate 105; a sliding mechanism is provided between the mounting plate 105 and the body 1; wherein, the sliding mechanism includes a guide rail 104, a guide block and a second driver, the guide rails 104 are provided in at least two groups and are arranged in parallel on the mounting plate 105, and the guide block is slidably connected to the guide rail 104; one end of the second driver is connected to the mounting plate 105, and the other end is connected to the guide block, and the top of the guide block is fixedly connected to the body 1; the second driver is used to push the guide block to move along the guide rail 104.

[0184] The mounting plate 105 is used to connect the machine body 1 and the worm gear, so that the position of the machine body 1 can change as the mounting plate 105 moves.

[0185] The guide rail 104 ensures that the machine body 1 maintains a straight line or a predetermined path during movement. The guide block is slidably connected to the guide rail 104, allowing the guide block to move along the length of the guide rail 104. Because the top of the guide block is fixedly connected to the machine body 1, when the guide block moves, the machine body 1 moves with it.

[0186] Therefore, when the second actuator is activated, it pushes the guide block along guide rail 104. Because the guide block is fixedly connected to the body 1, the body 1 moves with the movement of the guide block. In this way, the body 1 can slide on the mounting plate 105, further expanding the adjustment range of the body 1, thereby improving the adaptability and flexibility of the firefighting cannon.

[0187] According to a specific embodiment of the present disclosure, a gun barrel 2 for a fire-fighting projectile gun is provided, wherein: Figures 14 to 16 One specific embodiment is shown.

[0188] See Figures 14 to 16 As shown, the gun barrel 2 for the fire-fighting projection gun includes a tube body 21 and a spoiler 22, wherein the spoiler 22 is sleeved on one end of the tube body 21 and fixedly connected to the tube body 21; wherein the spoiler 22 is conical, and its diameter gradually increases in the direction away from the tube body 21, and a spoiler hole 23 is provided on the spoiler 22, wherein the spoiler hole 23 extends along the flow direction of the gas and passes through the spoiler 22, and one end of the spoiler hole 23 is located on the outer wall of the spoiler 22, and the other end is located on the inner wall of the spoiler 22.

[0189] By the techniques described above, the structural design of the spoiler 22 helps to reduce air resistance, so that the fire extinguishing bomb 6 can reach the target faster after leaving the gun barrel 2. Based on the design of the spoiler hole 23, when the fire extinguishing bomb 6 leaves the gun barrel 2, gas can flow out rapidly by the spoiler hole 23, thereby reducing the pressure in the gun barrel 2, helping the fire extinguishing bomb 6 to fly more stably. When the fire extinguishing bomb 6 leaves the gun barrel 2, the gas in the gun barrel 2 can produce high pressure because of sudden release. The spoiler hole 23 allows gas to flow out rapidly, thereby reducing the pressure in the gun barrel 2, reducing the resistance to the fire extinguishing bomb 6. Due to the existence of the spoiler hole 23, gas can produce certain disturbance when flowing out, and these disturbances help to improve the flight stability of the fire extinguishing bomb 6, making it easier to reach the predetermined target. In addition, the design of the spoiler hole 23 also helps to reduce the noise that the gun barrel 2 produces when launching.

[0190] In the present disclosure, the spoiler holes 23 are provided in plurality and are evenly spaced around the circumferential direction of the spoiler cover 22, so that the gas is distributed more evenly when flowing out, which helps to reduce the turbulence and resistance caused by uneven gas flow, thereby improving the flight stability and range of the fire extinguishing bomb 6.

[0191] The provision of multiple spoiler holes 23 can generate more disturbances, which help to improve the flight trajectory and stability of the fire extinguishing bomb 6.

[0192] It should be noted that the number and layout of the spoiler holes 23 can be adjusted as needed to adapt to different projection requirements and working environments.

[0193] In the present disclosure, six spoiler holes 23 are provided, so that the airflow disturbance effect can be maximized while ensuring the overall strength of the spoiler 22 .

[0194] In the present disclosure, the angle between the generatrix of the cone of the spoiler 22 and the axis is 25° to 35°. This design allows the gas to generate appropriate disturbances when flowing through the spoiler 22, thereby reducing air resistance and improving the flight stability and range of the fire extinguishing bomb 6.

[0195] Specifically, in the exemplary embodiment of the present disclosure, the angle between the cone generatrix of the spoiler 22 and the axis is 30°, which can achieve a better spoiler effect. In other embodiments, the angle between the cone generatrix of the spoiler 22 and the axis can also be set to 25° or 35°. In this regard, those skilled in the art can comprehensively consider factors such as the fire extinguishing bomb 6, the projection distance, and environmental conditions to determine the optimal angle range to achieve the best spoiler effect and projection performance.

[0196] In the present disclosure, the inner wall of the spoiler 22 is provided with a step, and the tube body 21 is provided with a groove body adapted to the step. The step on the inner wall of the spoiler 22 cooperates with the groove body on the tube body 21 to play a positioning and guiding role, helping the spoiler 22 and the tube body 21 to be quickly assembled.

[0197] In the present disclosure, the spoiler 22 is provided with a threaded hole, and a screw is screwed into the threaded hole to press against the tube body 21. When the screw is screwed into the threaded hole, a downward force is generated, and this force is evenly distributed on the tube body 21, thereby ensuring a tight connection between the spoiler 22 and the tube body 21, and effectively preventing loosening or falling off due to vibration or other external forces.

[0198] During maintenance, the screws can be easily screwed in or out by using a tool such as a screwdriver, thereby achieving installation or removal of the spoiler 22.

[0199] In the present disclosure, the threaded holes are provided in at least three groups and are evenly spaced around the circumference of the spoiler 22. By evenly distributing the threaded holes around the circumference of the spoiler 22, it is possible to ensure that the spoiler 22 is evenly supported and fixed at multiple points, thereby increasing the structural stability of the spoiler 22 and making it less likely to deform or be damaged when subjected to external forces.

[0200] In the present disclosure, the material of the tube body 21 is chromium-molybdenum steel. In this way, even under high pressure, high temperature or high stress environment, the tube body 21 made of chromium-molybdenum steel can maintain its structural integrity and stability and is not prone to deformation or cracking.

[0201] In addition, the chromium element in the chromium-molybdenum steel can form a dense oxide film, which can effectively prevent the tube body 21 from being damaged by oxidation and corrosion, so that the chromium-molybdenum steel tube body 21 can maintain a long service life even in harsh environments (such as high humidity, high salinity, etc.).

[0202] In the present disclosure, the spoiler 22 is made of aluminum alloy. Aluminum alloy has low density and high strength, allowing the spoiler 22 to be significantly lighter while maintaining sufficient strength. For a spoiler 22 that needs to be mounted on a moving or rotating component, reducing weight can lower energy consumption, improve response speed, and reduce the burden on the entire system.

[0203] In addition, a dense oxide film is easily formed on the surface of aluminum alloy, which can resist the erosion of various chemical substances, including water, air, certain acids and alkalis, so that the flow cover can maintain a long service life even in harsh environments and reduce the frequency of maintenance and replacement.

[0204] According to a specific embodiment of the present disclosure, a fire extinguishing bomb 6 for a fire-fighting projectile gun is provided, wherein: Figure 17 One specific embodiment is shown.

[0205] See Figure 17 As shown, the fire extinguishing bomb 6 for the fire-fighting projection gun includes a warhead 61, a middle water tank 62, a medicine tank 63, a chip tank 64 and a tail plate 65, all of which are coaxially arranged, wherein the two ends of the middle water tank 62 are respectively connected to the warhead 61 and the chip tank 64, the medicine tank 63 is connected to the chip tank 64, the chip tank 64 is provided with a chip 66, and the tail plate 65 is connected to the chip tank 64 so that the chip 66 is communicatively connected to the tail plate 65; wherein the tip of the warhead 61 is provided with an overflow hole, and a head plug 67 is sealed in the overflow hole.

[0206] The middle water tank 62 is located between the bullet 61 and the chip tank 64 and is usually used to store water or other fire extinguishing liquids. When the fire extinguishing bomb 6 is launched and hits the target, the liquid in the middle water tank 62 will flow out through the overflow hole of the bullet 61 to initially cool the fire source and extinguish the fire.

[0207] The agent compartment 63 is connected to the chip compartment 64 and is used to store fire extinguishing agents. This agent can be dry powder, foam, or other types of fire extinguishing agents, depending on the type of fire source. The agent is released when needed and acts together with the liquid in the intermediate water compartment 62 or independently to achieve a better fire extinguishing effect.

[0208] A chip 66 is provided on the chip compartment 64, and the chip 66 can record relevant information of the fire extinguishing bomb 6, such as production date, shelf life, batch number, etc. In addition, the chip 66 can also be connected to the tail plate 65 for communication, so that the status information of the fire extinguishing bomb 6 can be remotely monitored or controlled.

[0209] Tail plate 65 is located at the rear of the fire bomb 6 and is connected to the chip compartment 64. Tail plate 65 not only connects and secures the device but also communicates with the chip 66 via a communication link. This allows the status of the fire bomb 6 to be remotely read or controlled, improving the efficiency and safety of firefighting operations.

[0210] Among them, the tip of the bullet 61 is provided with an overflow hole, and a head plug 67 is sealed and inserted in the overflow hole. The overflow hole is designed to be used for filling liquid. During the filling operation, the liquid is poured from the overflow hole of the bullet 61. As the filling work continues, bubbles or foam are generated on the surface of the liquid due to the oscillation of the liquid. Therefore, after the filling is completed, the filling will continue until the bubbles or foam in the liquid overflow, and finally the head plug 67 is used for press-fitting. This can further reduce the internal gap, which can effectively eliminate bubbles and fill the bullet 61 with liquid, which is beneficial for the fire extinguishing bomb 6 to fly smoothly along the launch trajectory and avoid the flight trajectory being disturbed by the shaking of the liquid inside. In addition, since the head plug 67 is sharp, it has a certain wind-breaking effect, which can help the fire extinguishing bomb 6 to fly smoothly.

[0211] When the fire extinguishing bomb 6 is launched and hits the target, the liquid in the middle water tank 62 will flow out through the overflow hole of the bullet head 61. At the same time, the agent will be released, thereby acting together with the liquid in the middle water tank 62 or alone to achieve a better fire extinguishing effect.

[0212] With this technical solution, when the fire extinguishing bomb 6 is launched and impacts the target, the overflow hole in the bullet head 61 opens, allowing the liquid in the intermediate water tank 62 to quickly flow out. Simultaneously, the agent is released, acting together or independently with the liquid in the intermediate water tank 62 to achieve a better fire extinguishing effect. Through the communication connection between the chip 66 and the tail plate 65, the status information of the fire extinguishing bomb 6 can be remotely monitored and controlled, making firefighting operations more precise and efficient.

[0213] In the present disclosure, the inner wall of the intermediate water tank 62 is provided with strip grooves 68 for mounting swirl plates. The strip grooves 68 extend along the axis of the intermediate water tank 62. The swirl plates are embedded in the strip grooves 68, and the width of the swirl plates is smaller than the radius of the intermediate water tank 62. This arrangement enables the swirl plates to change the direction and velocity of the liquid, thereby forming a rotating flow within the intermediate water tank 62. This helps to enhance the kinetic energy of the liquid, promotes mixing of the fire extinguishing agent and water, and thus improves fire extinguishing efficiency.

[0214] The strip grooves 68 extend along the axis of the middle water tank 62, so that the swirl plates can be evenly distributed along the length of the middle water tank 62, ensuring that the liquid can effectively rotate in the entire middle water tank 62. At the same time, it can also prevent the liquid from being too concentrated or too sparse in some areas.

[0215] The swirl plate is embedded in the strip groove 68, allowing it to be securely fixed to the inner wall of the intermediate water tank 62. This ensures that the swirl plate remains firmly in place, preventing it from shifting or falling out under the influence of high-speed liquid. Furthermore, because the swirl plate's width is smaller than the radius of the intermediate water tank 62, it does not excessively occupy the space within the intermediate water tank 62, thus ensuring smooth liquid flow.

[0216] By setting a swirl plate in the intermediate water tank 62, the liquid can be rotated when flowing through the swirl plate. The rotating flow can not only increase the kinetic energy of the liquid, but also make the liquid and the fire extinguishing agent in the agent tank 63 better mixed, thereby improving the fire extinguishing effect.

[0217] In the present disclosure, the strip grooves 68 are provided in 2n strips, and the strip grooves 68 are symmetrically arranged in the intermediate water tank 62; wherein n is a natural number greater than or equal to 1.

[0218] Symmetrically positioning the strip grooves 68 within the intermediate water tank 62 and the symmetrical distribution of the swirl plates helps produce a more uniform and stable swirling flow, ensuring that the kinetic energy of the liquid is fully utilized throughout the intermediate water tank 62. As the number of swirl plates increases (by increasing the number of strip grooves 68), the water will experience a stronger swirl effect as it passes through them, helping to enhance the kinetic energy of the liquid and promote more uniform mixing of the fire extinguishing agent and water, thereby improving fire extinguishing efficiency.

[0219] By selecting different n values (n is a natural number greater than or equal to 1), the number and distribution of swirl plates can be flexibly adjusted. This can be optimized according to specific application scenarios and needs to achieve the best fire extinguishing effect.

[0220] The symmetrical distribution of the slots 68 and swirl plates helps maintain the structural stability of the intermediate water tank 62. Under the influence of high-velocity liquid and fire extinguishing agents, the intermediate water tank 62 needs to have a certain degree of pressure resistance. The symmetrical design ensures that the stress on the intermediate water tank 62 is evenly distributed, reducing the risk of stress concentration and damage.

[0221] In one embodiment of the present disclosure, the tip 67 is formed into a pointed shape that matches the tip profile of the bullet 61, thereby providing a wind-breaking effect. The tip shape of the tip 67 perfectly matches the tip profile of the bullet 61, ensuring precision and stability during the manufacturing and assembly of the fire-extinguishing bomb 6. Furthermore, the close fit between the two further reduces air resistance, improving the projectile's distance and accuracy.

[0222] The pointed tip of the head plug 67 acts as a windbreaker during the flight of the fire extinguishing bomb 6. As the fire extinguishing bomb 6 flies through the air, it encounters air resistance. However, the pointed tip of the head plug 67 effectively cuts and disperses the airflow, reducing the effect of air resistance on the flight trajectory of the fire extinguishing bomb 6. This windbreaking effect not only increases the flight speed and stability of the fire extinguishing bomb 6, but also helps ensure that the fire extinguishing bomb 6 accurately reaches its target location.

[0223] Before the fire extinguishing bomb 6 is projected, the head plug 67 must be securely sealed to prevent the overflow hole from leaking during flight. Once the fire extinguishing bomb 6 arrives at the target location or needs to release water, the head plug 67 must be able to open quickly and reliably to ensure that water can flow out smoothly.

[0224] In the present disclosure, the head plug 67 comprises a plug-in section and an integrally formed covering section. The plug-in section is structured to fit the overflow hole, allowing it to be press-fitted therein. The covering section fits snugly and stably into the end face of the bullet 61. The plug-in section is tightly and stably pressed into the overflow hole, effectively preventing water or fire extinguishing agent from leaking out of the overflow hole during launch, thus ensuring the effectiveness of the fire extinguishing bomb 6. The covering section fits snugly into the end face of the bullet 61, not only enhancing the connection stability between the head plug 67 and the bullet 61 but also providing a seal and protective effect.

[0225] Because the plug section of the head plug 67 fits snugly within the overflow hole, installation is generally straightforward. Furthermore, due to the tight fit between the cover section and the end face of the bullet 61, removal of the head plug 67 requires certain skills and tools. This ensures easy installation while preventing potential safety hazards caused by unauthorized removal.

[0226] In the present disclosure, the contact surfaces of the head plug 67 and the bullet 61 are both coated with sealant, thereby sealing the joint. This sealant, through temperature fluctuations, solvent evaporation, and chemical crosslinking, allows for stable bonding with the substrate, gradually solidifying into a plastic, viscoelastic, and elastic sealing material. Therefore, when the sealant is applied to the contact surfaces of the head plug 67 and the bullet 61, a stable, sealed connection is formed between the two, preventing liquid or gas leakage.

[0227] In the present disclosure, the chip compartment 64 is provided with a connection hole for mounting the medicine compartment 63 and a chip 66 slot for mounting the chip 66. The end of the medicine compartment 63 is screwed into the connection hole, ensuring a secure connection between the medicine compartment 63 and the chip compartment 64. The chip 66 is embedded in the chip 66 slot and connected to the chip compartment 64 via a first fastener. The first fastener (such as a screw or clip) securely connects the chip 66 to the chip 66 slot, preventing it from loosening or falling off due to vibration or impact. The chip 66 slot is used to accommodate the chip 66 and allows for electrical connection between the chip 66 and the chip compartment 64.

[0228] In the present disclosure, the tail plate 65 includes a substrate 651 made of plastic material and a plurality of copper rings 652 of different diameters. The substrate 651 is provided with a plurality of ring grooves corresponding to the copper rings 652 one by one, and the copper rings 652 are embedded in the ring grooves; the substrate 651 is melted to cover the copper rings 652; and the chip 66 is communicatively connected to different copper rings 652.

[0229] Copper ring 652 is designed with different diameters to represent different electrical channels or signal lines, thereby realizing different communication or control functions, thereby adapting to different electrical connection requirements. Copper ring 652 is embedded in the ring groove on the base plate 651, which ensures the stability and positioning accuracy of copper ring 652. After the copper ring 652 is embedded in the ring groove, a portion of the base plate 651 is melted to completely cover the copper ring 652, ensuring a tight connection between the copper ring 652 and the base plate 651 and providing additional protection and stability.

[0230] By changing the number, diameter, and layout of the copper rings 652 and the connection method of the chip 66, the tail plate 65 can be customized to meet specific needs.

[0231] In the present disclosure, the fire-fighting projection cannon also includes a controller, which is communicatively connected to the pneumatic device 3, the bullet feeding device 4, the material distribution device, the lifting device 8, the lifting device 9 and the positioning device to control the pneumatic device 3, the bullet feeding device 4, the material distribution device, the lifting device 8, the lifting device 9 and the positioning device to perform corresponding actions according to a preset program.

[0232] Among them, the pneumatic device 3, the feeding device 4, the material distribution device, the lifting device 8, the lifting device 9 and the positioning device are all equipped with corresponding detection devices, for example, the pneumatic device 3 is equipped with a pressure detection device, the feeding device 4 is equipped with a laser displacement sensor or radar, the material distribution device is equipped with a pressure sensor or infrared detection sensor, the lifting device 8 is equipped with an angle sensor, the lifting device 9 is equipped with a laser displacement sensor, and the positioning device is equipped with an angle sensor and a laser displacement sensor, etc. In this regard, those skilled in the art can flexibly configure it based on the technical concept of the present disclosure.

[0233] In the present disclosure, the controller is configured as a PLC logic controller.

[0234] Specifically, in the present invention, the controller may be configured as a central processing unit (CPU). In other embodiments, the controller may be configured as a digital signal processor (DSP), an application-specific integrated circuit (ASIC), or a field-programmable gate array (FPGA).

[0235] In the present disclosure, the controller is connected to the pneumatic device 3, the ammunition feeding device 4, the material distribution device, the lifting device 8, the lifting device 9, and the positioning device via cables. In other embodiments, the controller can also be connected to the pneumatic device 3, the ammunition feeding device 4, the material distribution device, the lifting device 8, the lifting device 9, and the positioning device via wireless communication modules such as WiFi modules or ZigBee modules. Those skilled in the art can flexibly configure these modules based on the technical concepts of this disclosure.

[0236] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
