Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a simple fire-fighting projection cannon machine. 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.

[0037] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0038] According to a specific embodiment of the present disclosure, a simple fire-fighting projectile cannon is provided, wherein: Figures 1 to 4 One specific implementation method is shown.

[0039] See Figures 1 to 4 As shown, the simple fire-fighting projectile gun includes: a body 1; a gun barrel 2 having a bore adapted for a fire-extinguishing bomb; the gun barrel 2 is movably connected to a gun mount 7, which is connected to the body 1; a pneumatic device 3, which is provided on the body 1 and is used to deliver high-pressure gas; a bullet feeding device 4, which is provided in two groups and is respectively connected to the body 1 and is used to guide the fire-extinguishing bombs one by one; and a material distribution device 5, which is provided with an arc groove for limiting the position of the fire-extinguishing bomb unit, and the axis of the arc groove is parallel to the gun barrel 2. axis; the gun barrel 2 is movably inserted in the arc groove, and the other end of the arc groove is sealed and connected to the pneumatic device 3; wherein, the discharge ports of the ammunition feeding device 4 are respectively located on both sides of the arc groove, so that the fire extinguishing bombs can roll into the arc groove one by one under the action of gravity; the material distribution device 5 also includes a pushing member 52, the fixed end of the pushing member 52 is connected to the gun mount 7, and the telescopic end thereof is connected to the gun barrel 2, and the pushing member 52 is used to push the gun barrel 2 to move along the arc groove and insert the fire extinguishing bomb on the arc groove into the bore of the gun barrel 2.

[0040] The body 1 serves as the basic structure of the simplified 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 5. The gun carriage 7, a support structure for the barrel 2, is connected to the body 1 and provides stable support. The barrel 2 has a bore compatible with fire-extinguishing projectiles for receiving and firing them. The pneumatic device 3 is mounted on the body 1 to deliver high-pressure gas.

[0041] The feed mechanism 4, mounted on the gun body 1, is used to dispense the fire-extinguishing bombs one by one. The feed mechanism 5, with its arc-shaped slots, precisely defines the position of the fire-extinguishing bombs, ensuring they are accurately delivered into the bore of the gun barrel 2. The pneumatic mechanism 3 enables the gun to deliver high-pressure gas, ejecting the fire-extinguishing bombs from the gun barrel 2 with great speed and force. This high-pressure launch capability allows the fire-extinguishing bombs to be launched over long distances, thereby extinguishing distant fires.

[0042] The working principle of this simple fire-fighting projectile cannon is as follows: first, according to the position of the fire point (or the point to be extinguished), the position of the entire simple fire-fighting projectile cannon is adjusted so that the barrel 2 is aimed at the fire point. The ammunition feeding device 4 delivers the fire-extinguishing bombs one by one toward the distributing device 5. After the fire-extinguishing bomb falls into the arc-shaped groove of the distributing device 5, the pushing member 52 pushes the barrel 2 toward the pneumatic device 3, so that the fire-extinguishing bomb is inserted into the bore of the barrel 2, that is, the fire-extinguishing bomb is loaded. When the barrel 2 moves into position, the pneumatic device 3 outputs high-pressure gas, thereby ejecting the fire-extinguishing bomb from the barrel 2 through the impact force of the instantaneous high-pressure gas, so that it can be accurately released at the fire point, thereby effectively extinguishing the fire source.

[0043] Through the above technical solution, the simplified firefighting cannon can automate or semi-automate the steps of feeding, dispensing, pushing, and firing during operation, 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 simplified firefighting cannon can quickly deliver fire extinguishing bombs to the fire source and effectively extinguish it, significantly improving firefighting efficiency and effectiveness.

[0044] In one embodiment provided in the present disclosure, the gun barrel 2 includes a tube body made of high-strength steel, and the inner wall surface of the tube body is formed with a coaxially arranged high-speed rotation section and a bore acceleration section. The inner wall surface of the high-speed rotation section is provided with a plurality of spiral grooves arranged in a spiral direction with the axis of the high-speed rotation section as a reference line, and the inner wall surface of the bore acceleration section is formed into a smooth curved surface.

[0045] The operating principle of this simplified fire-fighting projectile cannon is as follows: First, the position of the entire simplified 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 one by one toward the distribution device 5. After the fire-extinguishing bombs land in the arc-shaped groove of the distribution device 5, the pusher 52 pushes the barrel 2 toward the pneumatic device 3, thereby inserting the fire-extinguishing bomb into the bore of the barrel 2, that is, loading the fire-extinguishing bomb. Once the barrel 2 is in place, the pneumatic device 3 outputs high-pressure gas, which instantly gushes out the impact force of the high-pressure gas, ejecting the fire-extinguishing bomb from the barrel 2, allowing it to be accurately released at the fire point, effectively extinguishing the fire source.

[0046] The gun barrel 2 includes a tube body made of high-strength steel, and the inner wall surface of the tube body is formed with a coaxially arranged high-speed rotation section and a bore acceleration section. The inner wall surface of the high-speed rotation section is provided with a plurality of spiral grooves arranged in a spiral direction with the axis of the high-speed rotation section as the reference line, and the inner wall surface of the bore acceleration section is formed into a smooth curved surface.

[0047] At the moment compressed air is activated, the fire extinguisher bomb is propelled at high speed through the entry section. After reaching the second section along the tapered section, it begins to rotate until it exits barrel 2. After leaving barrel 2, the high-speed rotation of the fire extinguisher bomb, thanks to gyroscopic stability, keeps the bomb stable and prevents tumbling, extending the range and enhancing firefighting accuracy. The double-line casting tube allows the fire extinguisher bomb to move linearly within the tube, and the tail band at the fire extinguisher bomb deforms and embeds into the spiral groove, ensuring high-speed axial and circumferential rotation within the effective casting distance, achieving gyroscopic stability.

[0048] The tube is made of high-strength steel, which ensures the stability and wear resistance of the gun under high pressure and high speed conditions. The barrel acceleration section is located on the side close to the pneumatic equipment, while the high-speed rotation section is located on the side away from the pneumatic equipment. The inner wall surface of the barrel acceleration section is formed into a smooth curved surface, which helps the fire extinguishing bomb to quickly accelerate under the action of compressed air. The inner wall surface of the high-speed rotation section is provided with multiple spiral grooves. These spiral grooves are arranged in a spiral direction with the axis of the high-speed rotation section as the reference line, so that objects (such as fire extinguishing bombs) passing through this section can obtain rotational momentum.

[0049] There is a belt at the tail of the fire extinguishing bomb. When the fire extinguishing bomb moves linearly in the tube, the belt will deform and embed into the spiral groove, ensuring that the fire extinguishing bomb can make axial and circumferential high-speed rotation during the throwing process.

[0050] When compressed air is released and acts on the fire extinguishing bomb, the fire extinguishing bomb begins to move in the barrel 2. The fire extinguishing bomb first enters the chamber acceleration section. Because the inner wall surface of this section is smooth, the fire extinguishing bomb obtains high-speed propulsion in this section. As the fire extinguishing bomb continues to advance, it enters the high-speed rotation section. In this section, the fire extinguishing bomb is guided by the spiral groove and begins to rotate. After leaving the barrel 2, the high-speed rotating fire extinguishing bomb keeps the projectile stable and does not tumble under the gyroscopic stability effect, thereby can accurately extinguish fires at a longer distance.

[0051] The above technical solution, through the design of the spiral groove and smooth curved surface, and the coordination of the belt at the tail of the fire extinguishing bomb and the spiral groove, achieves effective acceleration and rotation of the fire extinguishing bomb within the barrel 2. This allows the fire extinguishing bomb to be propelled and rotated at high speed within the barrel 2, maintaining stable flight after leaving the barrel 2, thereby achieving a longer range. The provision of a high-speed rotation section imparts gyroscopic stability to the fire extinguishing bomb during flight, thereby maintaining flight stability and enabling the fire extinguishing bomb to be accurately delivered to the target fire extinguishing location, thereby achieving efficient, long-range, and accurate delivery of the fire extinguishing bomb.

[0052] In one embodiment provided herein, at least 20 spiral grooves are arranged evenly and spaced apart on the inner wall of the high-speed rotating section. This allows the fire-extinguishing bomb to be subjected to more frequent and uniform rotational forces as it passes through the high-speed rotating section, helping it reach a stable rotational speed more quickly and reducing flight instability that can result from uneven rotation. Furthermore, the multiple spiral grooves help disperse the impact and friction between the fire-extinguishing bomb and the inner wall of the tube. This dispersion helps reduce wear and heat accumulation during high-speed propulsion, thereby extending the service life of the gun and the fire-extinguishing bomb.

[0053] In the exemplary embodiment provided by the present disclosure, the number of the spiral grooves is 30, which can ensure the projection state of the fire extinguishing bomb and complete the accurate throwing of the fire extinguishing bomb.

[0054] In other embodiments, the number of spiral grooves can be adjusted according to actual needs. For example, the most suitable number of spiral grooves can be determined based on factors such as the size, shape, material, and required rotation speed and stability of the fire extinguishing bomb.

[0055] It should be noted that while increasing the number of spiral grooves can improve performance, it also adds more potential wear areas.

[0056] In one embodiment provided by the present disclosure, the spiral groove is U-shaped. The U-shaped groove design can provide a more stable guiding force, allowing the fire extinguishing bomb to rotate more smoothly when passing through the spiral groove, helping to reduce the shaking and irregular movement of the fire extinguishing bomb in the barrel 2, thereby improving the accuracy and reliability of shooting.

[0057] In addition, the U-shaped groove has a larger contact area than grooves of other shapes (such as V-shaped or rectangular grooves), making the contact between the outer wall of the fire extinguishing bomb and the wall of the spiral groove closer and more uniform, which helps to better transmit the rotational force and maintain the stability of the rotation.

[0058] Furthermore, the U-shaped groove is relatively simple to process and can be precisely manufactured through machining or mold forming, which is beneficial to reducing production costs and improving production efficiency.

[0059] In the present disclosure, the spiral groove has a width of 6 to 8 mm and a depth of 0.7 to 0.8 mm. A groove width of 6 to 8 mm is beneficial for stably transmitting rotational force. A groove width that is too narrow may result in insufficient contact area, affecting rotational stability; a groove that is too wide may increase processing difficulty and cost, and may also reduce rotational efficiency. A groove depth of 0.7 to 0.8 mm is beneficial for providing sufficient guiding force and rotational torque, ensuring that the fire extinguishing bomb has sufficient and stable rotational power.

[0060] Specifically, in one embodiment, the spiral groove has a groove width of 8 mm and a groove depth of 0.75 mm.

[0061] In one embodiment provided by the present disclosure, the straightness of the tube body is ≤0.01 mm, the cylindricity is ≤0.02 mm; and the roughness of the inner wall surface of the tube body is ≤Ra0.02.

[0062] Straightness ≤ 0.01mm, that is, the axis of the tube is kept extremely straight in the longitudinal direction, with a deviation of no more than 0.01mm. Cylindricity ≤ 0.02mm, that is, the degree of deviation of the cross-sectional shape of the tube from the ideal circle, which can reduce flow resistance and rotational instability caused by irregular shape.

[0063] The roughness is ≤ Ra0.02, giving the inner wall a mirror-like smoothness, which helps reduce the frictional resistance of the fire extinguishing bomb in the barrel 2 and improves the smoothness and accuracy of the shooting. At the same time, the smooth inner wall also helps reduce heat and wear caused by friction, extending the service life of the barrel 2.

[0064] This is beneficial to improving the shooting accuracy, range and reliability of the barrel 2, making the fire extinguishing bomb move and rotate stably in the barrel 2, and reducing shooting deviation and instability factors caused by the irregular shape or rough inner wall of the barrel 2.

[0065] In one embodiment provided herein, the tube is made of 42CrMo, a medium-carbon alloy steel with high yield strength and tensile strength. This allows the tube to withstand high loads and prevent deformation or cracking during firing.

[0066] This results in excellent hardenability for the tube, enabling heat treatment to achieve uniform microstructure and excellent mechanical properties. Heat treatment processes such as quenching and tempering can further enhance the hardness and wear resistance of 42CrMo, extending the tube's service life. In addition to its high strength and excellent hardenability, 42CrMo also exhibits good plasticity and toughness, meaning it can withstand shock and vibration while maintaining structural integrity and stability.

[0067] In barrel 2, the tube must withstand the impact of high-pressure fire extinguishing agents and the erosion of high-temperature combustion products. The high strength and excellent heat resistance of 42CrMo material enable it to maintain stable performance in this harsh environment. Due to its excellent wear and fatigue resistance, 42CrMo can extend the service life of the tube and reduce maintenance costs.

[0068] In the present disclosure, the fire extinguishing bomb includes a warhead, a medium water tank, a medicine tank, a chip tank and a tail plate, which are all coaxially arranged, wherein the two ends of the medium water tank are respectively connected to the warhead and the chip tank, the medicine tank is connected to the chip tank, a chip is provided on the chip tank, and the tail plate is connected to the chip tank so that the chip communication is connected to the tail plate; wherein, the tip of the warhead is provided with an overflow hole, and a head plug is provided in the overflow hole for sealing.

[0069] Specifically, the reagent compartment is connected to the chip compartment, which is equipped with a chip. The tailgate is connected to the chip compartment, allowing the chip to communicate with the tailgate. The chip can record relevant information about the fire extinguisher, such as the production date, expiration date, and batch number. Furthermore, the chip can communicate with the tailgate, allowing the status of the fire extinguisher to be remotely monitored or controlled. The tailgate not only serves as a connection and fixation function but also transmits data to the chip through a communication connection. This allows the status of the fire extinguisher to be remotely read or controlled, improving the efficiency and safety of firefighting operations.

[0070] Among them, the tip of the bullet is provided with an overflow hole, and a head plug is sealed in the overflow hole. The overflow hole is designed to be used for filling liquids. During the filling operation, the liquid is poured from the overflow hole of the bullet. 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 is used for press-fitting. This can further reduce the internal gaps, which can effectively eliminate bubbles and fill the bullet with liquid, which is beneficial for the fire extinguishing bomb to fly smoothly along the launch trajectory and avoid the flight trajectory being disturbed by the shaking of the liquid inside. In addition, because the head plug is sharp, it has a certain wind-breaking effect, which can help the fire extinguishing bomb fly smoothly.

[0071] When the fire extinguishing bomb is launched and hits the target, the liquid in the intermediate water tank will flow out through the overflow hole of the bullet head. At the same time, the agent will be released, which will work together with the liquid in the intermediate water tank or alone to achieve a better fire extinguishing effect.

[0072] When the fire extinguishing bomb is launched and impacts the target, the overflow hole in the warhead opens, allowing the liquid in the intermediate water chamber to quickly flow out. Simultaneously, the agent is released, acting together or independently with the liquid in the intermediate water chamber to achieve a better fire extinguishing effect. Through the communication connection between the chip and the tail plate, the status of the fire extinguishing bomb can be remotely monitored and controlled, making firefighting operations more precise and efficient.

[0073] In the present disclosure, the inner wall surface of the middle water bin is provided with strip grooves for installing swirl plates. The strip grooves extend along the axis direction of the middle water bin. The swirl plates are embedded in the strip grooves, and the width of the swirl plates is smaller than the radius of the middle water bin.

[0074] The strip grooves extend along the axis of the intermediate water tank, so that the swirl plates can be evenly distributed along the length of the intermediate water tank, ensuring that the liquid can effectively rotate in the entire intermediate water tank. At the same time, it can also prevent the liquid from being too concentrated or too sparse in some areas.

[0075] The swirl plate is embedded in the strip groove, allowing it to be firmly fixed to the inner wall of the intermediate water tank. This ensures that the swirl plate remains firmly in place, preventing it from moving or falling off under the influence of high-speed liquid. Furthermore, because the swirl plate's width is smaller than the radius of the intermediate water tank, it does not occupy excessive space in the intermediate water tank, thus ensuring smooth liquid flow.

[0076] By installing a swirl plate in the intermediate water tank, 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 better mixed, thereby improving the fire extinguishing effect.

[0077] In the present disclosure, the distributing device 5 includes a receiving seat 51, a sealing seat, an air storage pipe and a pushing member 52. The receiving seat 51 is provided with an arc groove for limiting the position of the fire extinguishing bomb. The front end of the arc groove is sealed and connected to the bearing seat, and the rear end is sealed and connected to the sealing seat; one end of the air storage pipe is connected to the pneumatic device 3, and the other end is connected to the sealing seat through a control pipe; a control valve is provided on the control pipe to control the on and off of the airflow; the moving end of the pushing member 52 is connected to the gun barrel 2, and the moving direction of the moving end is parallel to the axial direction of the gun barrel 2, so that the gun barrel 2 can move along the arc groove to approach or move away from the sealing seat.

[0078] The arcuate groove on the receiving seat 51 defines the position of the fire-extinguishing bomb, ensuring its stable resting and movement during the dispensing process. The arcuate groove design allows the fire-extinguishing bomb to be accurately guided into its designated position by the left and right feed mechanisms 4. The front end of the arcuate groove is sealed to the bearing seat, and the rear end is sealed to the sealing seat. This design ensures the sealing of the arcuate groove, preventing gas leaks or the fire-extinguishing bomb from falling during the dispensing and pushing process.

[0079] One end of the gas storage pipe is connected to the pneumatic device 3, and the other end is connected to the sealing seat via a control pipe. The control pipe is equipped with a control valve to control the flow of air. When the fire extinguishing bomb is pushed into the bore of the gun barrel 2, the control valve opens, and the high-pressure gas delivered by the pneumatic device 3 enters the sealing seat through the gas storage pipe and the control pipe, thereby propelling the fire extinguishing bomb out of the gun barrel 2.

[0080] The moving end of the pusher 52 is connected to the barrel 2, and its direction of movement is parallel to the axis of the barrel 2. As the pusher 52 moves, it pushes the barrel 2 along the arcuate groove, moving it closer to or further from the sealing seat. When the barrel 2 reaches the desired position, the fire extinguishing bomb is pushed into the bore of the barrel 2, ready for firing.

[0081] When the barrel 2 abuts the sealing seat, the fire extinguishing bomb has been successfully delivered into the barrel 2. The control valve is opened, and the pneumatic device 3 provides airflow to the sealing seat through the gas storage pipe and control pipe. The high-pressure gas propels the fire extinguishing bomb 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 is ejected, the pushing member 52 moves the barrel 2 away from the sealing seat and returns to its initial position, ready for the next delivery.

[0082] The design of the two feeding devices 4 and the arcuate grooves enables efficient, stable, and consistent feeding of fire-extinguishing bombs, which helps reduce waiting time and improve fire-fighting efficiency. The pusher 52 ensures that the barrel 2 can move precisely along the arcuate groove, pushing the fire-extinguishing bomb into the bore of the barrel 2 and preparing it for firing. A control valve controls the on / off flow of air to ensure safety during the firing process and prevent accidents. The entire feeder 5 has a rational design and a stable structure, capable of reliable operation in various environments and meeting the needs of firefighting.

[0083] The pusher 52 consists of a clamp 53 and a linear module. The linear module is connected to the barrel 2 via the clamp 53, pushing the barrel 2 within the arcuate groove. The clamp 53 secures and connects the barrel 2 to the linear module. During assembly, the clamp 53 tightly wraps around the outer surface of the barrel 2, ensuring stability and accuracy during movement. In a simple fire-fighting projectile gun, the linear module is connected to the barrel 2 via the clamp 53. When the linear module is activated, it pushes the barrel 2 within the arcuate groove, enabling automatic loading of the fire extinguishing projectile.

[0084] When a fire extinguisher bomb needs to be loaded from the magazine into barrel 2, the controller sends a command to the linear module. Upon receiving the command, the linear module activates the motor, which, through the cooperation of the guide rails and positioning blocks, propels barrel 2 within the arcuate groove. Thanks to the tight connection of the clamp 53, barrel 2 maintains a stable position during movement, ensuring that the fire extinguisher bomb enters barrel 2 accurately. When barrel 2 reaches the appropriate position, the linear module stops, indicating that the fire extinguisher bomb has been successfully loaded and can be fired.

[0085] When a fire extinguisher bomb needs to be loaded from the magazine into barrel 2, the controller sends a command to the linear module. Upon receiving the command, the linear module activates the motor, which, through the cooperation of the guide rails and positioning blocks, propels barrel 2 within the arcuate groove. Thanks to the tight connection of the clamp 53, barrel 2 maintains a stable position during movement, ensuring that the fire extinguisher bomb enters barrel 2 accurately. When barrel 2 reaches the appropriate position, the linear module stops, indicating that the fire extinguisher bomb has been successfully loaded and can be fired.

[0086] In one embodiment provided herein, the bearing seat 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.

[0087] In addition, a flexible sealing ring is provided on the sealing seat. 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 and the barrel 2 or other connecting parts.

[0088] In the present disclosure, the ammunition feeding device 4 includes an ammunition feeding chamber, which is tilted and connected to the body 1. This allows the fire extinguishing bombs to roll down the inclined surface of the feeding chamber wall. The tilt angle of the feeding chamber is 20° to 50°. This angle design ensures that the fire extinguishing bombs have sufficient kinetic energy to fall into the arc-shaped groove. At the same time, it can also slow down the rolling speed of the fire extinguishing bombs to a certain extent, thereby reducing the impact on the arc-shaped groove and reducing the impact of the fire extinguishing bombs.

[0089] Furthermore, a buffer plate is provided in the ammunition feed chamber, which can play a role in vibration reduction and deceleration to varying degrees, helping the fire extinguishing bomb to roll down the arc groove in a stable state, thereby playing a certain protective role.

[0090] Specifically, the buffer plate is configured as a rubber plate or a polyurethane plate.

[0091] In the present disclosure, the simplified fire-fighting projectile gun also includes a lifting device 6, one end of which is connected to the body 1 and the other end to the gun carriage 7, to adjust the gun carriage 7's elevation angle. The elevation angle refers to the angle of the gun barrel 2 or muzzle relative to the horizontal plane. During firefighting, the elevation angle of the gun carriage 7 needs to be adjusted based on the height, distance, and location of the fire source to ensure that the fire-extinguishing projectiles are accurately delivered to the target.

[0092] Specifically, the lifting device 6 can be equipped with an electric drive system or a hydraulic drive system. By controlling these drive systems, the lifting height of the lifting device 6 can be precisely adjusted, thereby changing the elevation angle of the gun carriage 7 and indirectly changing the position of the gun barrel 2. When the elevation angle of the gun carriage 7 needs to be increased, the lifting device 6 will extend or rise, raising the gun carriage 7 relative to the body 1; conversely, when the elevation angle needs to be reduced, the lifting device 6 will shorten or descend, lowering the gun carriage 7, ensuring that the fire extinguishing bomb can accurately reach the target.

[0093] In the embodiment shown in the present disclosure, the lifting device 6 is configured as a cylinder, which is rotatably connected to the body 1, and the telescopic shaft of the cylinder is rotatably connected to the gun carriage 7, so that the lifting and lowering of the gun carriage 7 can be achieved by the extension and contraction of the cylinder, thereby completing the adjustment of the position of the gun barrel 2.

[0094] In one embodiment provided herein, the simplified fire-fighting projectile cannon further includes a positioning device 9. The positioning device 9 has a fixed end connected to the loading platform 8 and a movable end connected to the body 1, thereby driving the body 1 to rotate along the vertical axis. With the vertical axis as the rotational center, the positioning device 9 enables the body 1 to rotate 360 degrees, allowing the simplified fire-fighting projectile 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 positioning device 9 can also quickly adjust the firing angle, shortening response time and improving firefighting efficiency.

[0095] Specifically, the positioning device 9 is configured as an indexer in the prior art.

[0096] In one embodiment, the simple fire-fighting projection cannon also includes a controller, which is communicatively connected to the pneumatic device, the bullet feeding device and the material distribution device to control the pneumatic device, the bullet feeding device and the material distribution device to perform corresponding actions according to a preset program.

[0097] 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 controller. This system enables precise control of simple 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.

[0098] It should be noted that, in this disclosure, the lifting device 6 and the positioning device 9 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, as well as its horizontal position and posture. 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.

[0099] The pneumatic device 3, the feeding device 4, the material distribution device 5, the lifting device 6, and the positioning device 9 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 5 is equipped with a pressure sensor or an infrared detection sensor, the lifting device 6 is equipped with an angle sensor, and the positioning device 9 is equipped with an angle sensor and a laser displacement sensor. In this regard, those skilled in the art can flexibly configure the devices based on the technical concept of the present disclosure.

[0100] In the present disclosure, the controller is configured as a PLC logic controller.

[0101] 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).

[0102] In the present disclosure, the controller is connected to the pneumatic device 3, the ammunition feeding device 4, the material distribution device 5, and the lifting device 6 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 5, and the lifting device 6 via wireless communication modules such as WiFi modules and ZigBee modules. Those skilled in the art can flexibly configure these modules based on the technical concepts of the present disclosure.

[0103] 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.
