Description

Technical Field

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

[0002] Fire monitor is a highly efficient fire-fighting 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 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, and the fire cannon can adjust the spray angle and direction of its gun head through the control motor controlling the horizontal pitch and rotation mechanism.

[0004] When handling serious fires with this large-flow mobile remote-controlled fire cannon fire-fighting component, the pickup truck is first driven as a mobile carrier to quickly reach the fire scene to extinguish the fire. After parking at the best fire-fighting location, a fire hose is used to connect the water inlet of the water collector and the water outlet of the water supply pipeline of the rear-field fire truck. The rear-field fire truck is operated to supply water to the front-field fire-fighting component to the rated working pressure. The control motor controls the horizontal pitch and rotation mechanism to adjust the spray angle and direction of the cannon head to the best fire-fighting position for accurate and rapid fire-fighting.

[0005] However, in the application test, it was found that because the fire extinguishing component is installed on a pickup truck, it is only suitable for sites with flat roads and cannot be used in mountains, slopes or soft foundations, so its application range is small. At the same time, due to its location limitation, it will also affect the accuracy of the fire extinguishing bomb projection position, resulting in extremely limited application range of fire extinguishing.

[0006] Furthermore, when loading the fire extinguishing bomb, the operation is extremely inconvenient, and it is difficult to load the bomb continuously and efficiently. In addition, when the fire extinguishing bomb falls, it is very easy to be scratched, which causes the structure of the fire extinguishing bomb to be affected before it is fired. When the fire extinguishing bomb is fired, due to the structure of the gun body and the form of the seat roller, not only will the gun body structure change, but also the overall position of the pickup truck will be displaced. Manual secondary adjustment of the gun machine position is required, and the operation is relatively cumbersome, which not only affects the continuity of the fire extinguishing bomb firing, but also greatly reduces the accuracy of the fire extinguishing bomb landing position, affecting the fire extinguishing 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 structure of the gun body, the shells are greatly affected by the airflow when fired, and are prone to rotation or tilt during flight, making it difficult to land accurately along the predetermined route. Therefore, the superposition of various factors makes the actual landing position of the shells unpredictable relative to the target fire extinguishing position, causing technical obstacles in firefighting work.

[0009] Therefore, in view of the problems existing in the current gun machine, such as poor accuracy in the projection direction of the fire extinguishing bomb, unstable projection range of the fire extinguishing bomb, 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 prior art. Utility Model Content

[0010] The utility model aims to provide a bullet feeding device for a fire-fighting projectile gun machine, so as to solve the technical problem that when filling the fire-extinguishing bombs, the operation is extremely inconvenient and it is difficult to perform continuous and efficient filling.

[0011] In order to achieve the above-mentioned object, the utility model provides a bullet feeding device for a fire-fighting projectile cannon, comprising:

[0012] The positioning plate is provided with a feeding port for passing only a single fire extinguishing bomb;

[0013] A magazine for storing fire extinguishing bombs; the magazine is movably connected to the positioning plate via a positioning block;

[0014] A magazine is provided below the positioning plate, one end of which is connected to the feeding port, and the other end of which is connected to the arc groove on the material distribution device; and

[0015] A first linear drive component, one end of which is connected to the positioning plate and the other end of which is connected to the positioning block. The first linear drive component is used to push the positioning block towards or away from the discharge port so that the fire extinguishing bombs in the magazine can fall into the magazine under the action of gravity.

[0016] Optionally, a plurality of buffer plates are provided in the ammunition feeding bin, and the buffer plates are respectively arranged on two side walls of the ammunition feeding bin.

[0017] Optionally, the buffer plates on the two side walls are staggered along the height direction of the magazine.

[0018] Optionally, the contact surface of the buffer plate is configured as a curved surface.

[0019] Optionally, the buffer plate is configured as a rubber plate or a polyurethane plate.

[0020] Optionally, the ammunition storage magazine and the ammunition supply magazine are both arranged at an angle so that the axis of the fire extinguishing bomb is parallel to the axis of the gun barrel.

[0021] Optionally, a partition is provided in the ammunition storage bin to separate the ammunition storage bin into two chambers; wherein the size of each chamber is set to enable only the fire extinguishing bombs to be dropped in the same posture.

[0022] Optionally, the first linear drive member comprises:

[0023] A nut seat is arranged on the machine body, and a threaded hole and a through hole are provided on the nut seat;

[0024] A screw rod is inserted into the threaded hole and rotatably connected to the body;

[0025] a polished rod inserted into the through hole, and both ends of the polished rod are rotatably connected to the body; and

[0026] A first motor is disposed on the positioning plate, and an output shaft thereof is drivingly connected to the screw rod;

[0027] Among them, one end of the positioning block is sleeved on the polished rod, and the other end is screwed to the lead screw. When the first motor rotates, the positioning block is driven to move on the lead screw.

[0028] Optionally, the magazines and the first linear drive are configured in two groups, and the magazines are respectively arranged on both sides of the discharge port; the first linear drive is correspondingly connected to the magazines.

[0029] Optionally, a limit switch is provided on the positioning plate, and the limit switch is communicatively connected to the controller and the first linear drive member.

[0030] The first linear drive controls the falling of the fire extinguishing bomb by pushing the magazine close to or away from the discharge port. Specifically, one end of the first linear drive is connected to the positioning plate, and the other end is connected to the magazine. The first linear drive is used to push the magazine close to or away from the discharge port so that the fire extinguishing bomb can fall into the magazine under the action of gravity. When it is necessary to replenish the fire extinguishing bomb in the magazine, the first linear drive pushes the magazine close to the discharge port so that the fire extinguishing bomb naturally falls into the magazine under the action of gravity; when the number of fire extinguishing bombs in the magazine is sufficient or the feeding needs to be suspended, the first linear drive pushes the magazine away from the discharge port to suspend the falling of the fire extinguishing bomb.

[0031] In the initial state, the magazine is located away from the discharge port to ensure that no fire extinguishing bombs fall. When the fire-fighting cannon needs to launch a fire-extinguishing bomb, the first linear drive component starts to push the magazine along the screw toward the positioning plate until the fire-extinguishing bomb in the magazine is aligned with the discharge port. Under the action of gravity, the fire-extinguishing bomb falls into the magazine through the discharge port. Under the action of gravity or other conveying devices, the fire-extinguishing bomb in the magazine falls into the arc groove of the distribution device. The distribution device guides the fire-extinguishing bombs to the barrel one by one for preparation for firing. When the fire-extinguishing bomb is in place or in other situations where it is necessary to suspend the supply of bombs, the first linear drive component starts in the reverse direction to push the magazine away from the discharge port and suspend the falling of the fire-extinguishing bomb. In this way, not only the stable supply of fire-extinguishing bombs is ensured, but also the safety and reliability of the entire fire-fighting cannon is improved.

[0032] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0054] According to a specific embodiment of the present disclosure, a firefighting projection cannon is provided, wherein: Figures 1 to 17 One specific implementation method is shown.

[0055] See also Figures 1 to 17As shown, the fire-fighting projection gun machine comprises: a machine body 1; a gun barrel 2, which has a bore adapted to the 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 machine body 1; a pneumatic device 3, which is arranged on the machine body 1, and the pneumatic device 3 is used to deliver high-pressure gas; a bullet feeding device 4, which is arranged on the machine body 1, and the bullet feeding device 4 is used to guide the fire-extinguishing bombs 6 one by one; and a material distribution device 5, which is provided with an arc groove 511 for limiting the position of the single fire-extinguishing bomb 6, and the axis of the arc groove 511 is parallel to the axis of the gun barrel 2; one end of the material distribution device 5 is connected to the bullet feeding device 4 to receive the fire-extinguishing bomb 6. The fire extinguishing bomb 6 is guided out from the bullet feeding device 4; the other end of the material distribution device 5 is connected to the pneumatic device 3; the material distribution device 5 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.

[0056] The body 1 is the basic structure of the entire fire-fighting projectile gun machine, and other components such as the gun barrel 2, the pneumatic device 3, the bullet feeding device 4 and the material distribution device 5 can be conveniently installed on the body 1 in a direct or indirect manner. The gun frame 111 is a supporting structure of the gun barrel 2, which is connected to the body 1 to provide stable support for the gun barrel 2. The gun barrel 2 has a bore adapted to the fire-extinguishing bomb 6 for accommodating and launching the fire-extinguishing bomb 6. The pneumatic device 3 is arranged on the body 1 for delivering high-pressure gas.

[0057] The feeding device 4 is arranged on the machine body 1, and is used to guide the fire extinguishing bombs 6 one by one. The material distribution device 5 can accurately define the position of the fire extinguishing bomb 6 through the design of the arc groove 511, ensuring that the fire extinguishing bomb 6 can be accurately pushed into the bore of the barrel 2. The setting of the pneumatic device 3 enables the gun machine to deliver high-pressure gas, thereby ejecting the fire extinguishing bomb 6 from the barrel 2 at a higher speed and force. This high-pressure emission capability can enable the fire extinguishing bomb 6 to be launched to a longer distance, thereby extinguishing a fire at a distant fire extinguishing point.

[0058] The working principle of the fire-fighting projectile gun machine is as follows: first, according to the position of the fire point, the position of the entire fire-fighting projectile gun machine is adjusted so that the gun barrel 2 is aimed at the fire point. The bullet feeding device 4 delivers the fire-extinguishing bombs 6 one by one toward the material distribution device 5. After the fire-extinguishing bomb 6 falls into the arc groove 511 of the material distribution device 5, the pushing member 55 pushes the gun barrel 2 to move toward the pneumatic device 3, so that the fire-extinguishing bomb 6 is inserted into the bore of the gun barrel 2, that is, the fire-extinguishing bomb 6 is loaded. When the gun barrel 2 moves into place, the pneumatic device 3 outputs high-pressure gas, thereby ejecting the fire-extinguishing bomb 6 from the gun barrel 2 through the impact force of the high-pressure gas that gushes out instantly, so that it can be accurately released at the fire point, thereby effectively extinguishing the fire source.

[0059] Based on the above technical solution, the steps of feeding, distributing, pushing and launching of the fire-fighting projectile cannon can be automated or semi-automated, which greatly shortens the preparation time and launching time and improves the efficiency of fire response. Through the combination of precise aiming at the fire source and high-pressure launching capability, the fire-fighting projectile cannon can quickly deliver the fire-extinguishing bomb 6 to the fire source and effectively extinguish the fire, which can significantly improve the efficiency and effect of fire extinguishing and provide strong support for fire response.

[0060] In an embodiment provided in the present disclosure, the gun barrel 2 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, wherein 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.

[0061] 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 gas flow direction, which can optimize the flow characteristics of the gas, reduce the turbulence and eddy current of the gas in the barrel 2, and improve the accuracy of the launch.

[0062] The design of the conical spoiler 22 enhances the overall structural stability of the gun barrel 2, enabling it to withstand the impact force brought by the high-pressure gas. At the same time, it can also reduce air resistance, allowing the fire extinguishing bomb 6 to obtain a higher speed and a longer range when firing.

[0063] In the present disclosure, the fire extinguishing bomb 6 includes a warhead 61, a middle water bin 62, a medicine bin 63, a chip bin 64 and a tail plate 65, all of which are coaxially arranged, wherein the two ends of the middle water bin 62 are respectively connected to the warhead 61 and the chip bin 64, that is, the middle water bin 62 is located between the warhead 61 and the chip bin 64, and is used to store water or other fire extinguishing liquids. The medicine bin 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.

[0064] Specifically, the reagent bin 63 is connected to the chip bin 64, the chip bin 64 is provided with a chip 66, and the tail plate 65 is connected to the chip bin 64 so that the chip 66 is communicatively connected to the tail plate 65; 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 communicatively connected with the tail plate 65, so that the status information of the fire extinguishing bomb 6 can be remotely monitored or controlled. The tail plate 65 not only plays a connecting and fixing role, but also transmits data with the chip 66 through a communication connection. This allows the status information of the fire extinguishing bomb 6 to be remotely read or controlled, thereby improving the efficiency and safety of the fire extinguishing operation.

[0065] 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 design of the overflow hole can be used for filling liquid. When the filling operation is performed, 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 based on 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 and has a certain wind-breaking effect, it can help the fire extinguishing bomb 6 to fly smoothly.

[0066] When the fire extinguishing bomb 6 is fired 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.

[0067] When the fire extinguishing bomb 6 is fired and hits the target, the overflow hole of the bullet 61 will open, and the liquid in the middle water tank 62 will flow out quickly. At the same time, the agent will be released, so as to work together or alone with the liquid in the middle 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.

[0068] In the present disclosure, the distributing device 5 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 groove 511 for limiting the position of the fire extinguishing bomb 6. The front end of the arc groove 511 is sealed and connected to the bearing seat 56, and the rear end is sealed and connected to the sealing seat 52; 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 airflow; the moving end of the pushing member 55 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 511 to approach or move away from the sealing seat 52.

[0069] The arc groove 511 on the receiving seat 51 is used to limit the position of the fire extinguishing bomb 6, ensuring that the fire extinguishing bomb 6 can stay and move stably during the material distribution process. The design of the arc groove 511 allows the fire extinguishing bomb 6 to be accurately introduced into the specified position of the arc groove 511 under the action of the bullet feeding devices 4 on the left and right sides. The front end of the arc groove 511 is sealed and connected to the bearing seat 56, and the rear end is sealed and connected to the sealing seat 52. Such a design ensures the sealing of the arc groove 511, avoiding gas leakage or falling of the fire extinguishing bomb 6 during the material distribution and pushing process.

[0070] One end of the gas storage pipe 54 is connected to the pneumatic device 3, and the other end is connected to the sealing seat 52 through the control pipe 57. The control pipe 57 is provided with a control valve 58 for controlling the on and off of the airflow. 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 pipe 54 and the control pipe 57, thereby pushing the fire extinguishing bomb 6 to be ejected from the gun barrel 2.

[0071] The moving end of the pusher 55 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. When the pusher 55 moves, it can push the gun barrel 2 to move along the arc groove 511, so as to approach or move away from the sealing seat 52. When the gun barrel 2 moves to a suitable position, the fire extinguishing bomb 6 is pushed into the bore of the gun barrel 2, ready for firing.

[0072] Through the design of two groups of feeding devices 4 and arc groove 511, efficient, stable and coherent feeding of fire extinguishing bomb 6 can be achieved, which is beneficial to reduce waiting time and improve fire extinguishing efficiency. Among them, the pusher 55 ensures that the barrel 2 can move accurately along the arc groove 511, pushes the fire extinguishing bomb 6 into the bore of the barrel 2, and is ready for firing. The on and off of the airflow is controlled by the control valve 58 to ensure safety during the firing process and avoid accidents. The entire material distribution device 5 is reasonably designed and stable in structure, can work reliably in various environments, and meets the needs of fire fighting.

[0073] 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 the simultaneous falling of multiple fire extinguishing bombs 6.

[0074] 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, 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 bomb 6 passing through the discharge port. The feeding magazine 43 is arranged below the positioning plate 41, and one end of the feeding magazine 43 is connected to the discharge port, and the other end is connected to the arc groove 511 on the material distribution device 5; 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 close to or away from the discharge port, so that the fire extinguishing bomb 6 can fall into the feeding magazine 43 under the action of gravity.

[0075] Specifically, when the fire extinguishing bomb 6 needs to be added to the ammunition supply bin 43, the first linear drive member 44 pushes the ammunition storage bin 42 close to the discharge port until the fire extinguishing bomb 6 in the ammunition storage bin 42 is aligned with the discharge port, so that the fire extinguishing bomb 6 naturally falls into the ammunition supply bin 43 under the action of gravity; when the number of fire extinguishing bombs 6 in the ammunition supply bin 43 is sufficient or the ammunition supply needs to be suspended, the first linear drive member 44 moves in the opposite direction, pushes the ammunition storage bin 42 away from the discharge port, and suspends the falling of the fire extinguishing bomb 6. In this way, a stable and continuous supply of the fire extinguishing bomb 6 is ensured.

[0076] 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 of which is connected to the gun carriage 111 to adjust the elevation angle of the gun carriage 111 .

[0077] The pitch angle refers to the angle of the gun barrel 2 or the muzzle relative to the horizontal plane. In the fire fighting process, according to the height, distance and position of the fire source, the pitch angle of the gun carriage 111 needs to be adjusted to ensure that the fire extinguishing bomb 6 can accurately shoot at the target.

[0078] The 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 the lifting device 8 can be accurately adjusted, thereby changing the elevation angle of the gun carriage 111, and indirectly changing the position of the gun barrel 2. When the elevation angle of the gun carriage 111 needs to be increased, the lifting device 8 will extend or rise, so that the gun carriage 111 is raised relative to the body 1; conversely, when the elevation angle needs to be reduced, the lifting device 8 will shorten or descend, so that the gun carriage 111 is lowered, ensuring that the fire extinguishing bomb 6 can accurately shoot at the target.

[0079] In the present disclosure, the fire-fighting projection cannon also includes a lifting device 9, and the lifting device 9 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.

[0080] The lifting device 9 is connected to the body 1 of the fire-fighting projectile gun through the loading platform, and its main function is to adjust the horizontal position, height and stability of the entire device. Each support mechanism 91 can be independently controlled to rise and fall, so that the angle of the gun barrel 2 can be adjusted according to different use environments, thereby aiming at the target position to achieve the best fire extinguishing effect.

[0081] In the embodiment provided in the present disclosure, the fire-fighting projection cannon also includes a positioning device, a fixed end of which is connected to the loading platform, and a movable end is connected to the body 1 to drive the body 1 to rotate along the vertical direction as the rotation center.

[0082] The positioning device uses the vertical direction as the rotation center, so that the body 1 can rotate 360 ​​degrees, so that the fire-fighting projection cannon can cover a wider area. No matter which direction the fire source is located, the cannon can quickly and accurately adjust the shooting angle, thereby improving its ability to cope with different fire source locations. When the location of the fire source changes, the fire-fighting projection cannon can also quickly adjust the shooting angle through the positioning device, shortening the response time and improving the fire-fighting efficiency.

[0083] In complex environments such as high-rise buildings, forests, and large warehouses, the occurrence of fires is often unpredictable. The fire projection cannon equipped with a positioning device can quickly locate and extinguish the fire source, reducing the loss of life and property caused by the fire. At the same time, the fire projection cannon is also suitable for some special occasions, such as offshore oil platforms, nuclear power plants and other high-risk areas, and has good practicality.

[0084] 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 5 to control the pneumatic device 3, the bullet feeding device 4 and the material distribution device 5 to perform corresponding actions according to a preset program.

[0085] The controller integrates real-time information such as sensor data and fire scene images, and combines preset fire-fighting strategies and operator instructions to form an intelligent control system. The system can achieve precise control of fire-fighting cannons, ensuring that fire-fighting operations can be carried out quickly and effectively in the fire scene. At the same time, the controller can also record and analyze data during the fire-fighting process to provide reference and basis for subsequent fire-fighting work.

[0086] In the present disclosure, the lifting device 8, the lifting device 9 and the positioning device are also communicatively connected to the controller. Among them, the lifting device 8, the lifting device 9 and the positioning device are mainly used to drive the parts of the gun machine that need to quickly and accurately control the action, such as the pitch angle of the gun barrel 2, the height of the gun barrel 2, and the position and posture of the gun barrel 2 in the horizontal plane. The controller sends instructions to the pneumatic device 3 to adjust the posture and angle of the gun machine according to a preset sequence or according to the real-time situation of the fire scene to ensure the accuracy and effect of the projection.

[0087] 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.

[0088] 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.

[0089] See also Figures 1 to 9 As shown, the ammunition feeding device 4 for the fire-fighting projection cannon 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.

[0090] 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.

[0091] The ammunition supply bin 43 is disposed below the positioning plate 41, and one end of the ammunition supply bin 43 is connected to the discharge port, and the other end is connected to the arc groove 511 on the material distribution device 5. When the fire extinguishing bomb 6 falls from the discharge port, it will directly enter the ammunition supply bin 43, and enter the arc groove 511 of the material distribution device 5 through the other end of the ammunition supply bin 43.

[0092] The first linear drive 44 controls the falling of the fire extinguishing bomb 6 by pushing the magazine 42 close to or away from the discharge port. Specifically, one end of the first linear drive 44 is connected to the positioning plate 41, and the other end is connected to the magazine 42. The first linear drive 44 is used to push the magazine 42 close to or away from the discharge port, so that the fire extinguishing bomb 6 can fall into the magazine 43 under the action of gravity. When it is necessary to replenish the fire extinguishing bomb 6 in the magazine 43, the first linear drive 44 pushes the magazine 42 close to the discharge port, so that the fire extinguishing bomb 6 naturally falls into the magazine 43 under the action of gravity; when the number of fire extinguishing bombs 6 in the magazine 43 is sufficient or the feeding needs to be suspended, the first linear drive 44 pushes the magazine 42 away from the discharge port to suspend the falling of the fire extinguishing bomb 6.

[0093] In the initial state, the magazine 42 is located away from the discharge port to ensure that no fire extinguishing bombs 6 fall. When the fire-fighting projectile gun needs to launch a fire-extinguishing bomb 6, the first linear drive 44 is started to push the magazine 42 to move along the screw toward the positioning plate 41 until the fire-extinguishing bomb 6 in the magazine 42 is aligned with the discharge port. Under the action of gravity, the fire-extinguishing bomb 6 falls into the magazine 43 through the discharge port. Under the action of gravity or other conveying devices, the fire-extinguishing bomb 6 in the magazine 43 falls into the arc groove 511 of the distribution device 5. The distribution device 5 guides the fire-extinguishing bombs 6 to the barrel 2 one by one to prepare for firing. When the fire-extinguishing bomb 6 is in place or in other situations where it is necessary to suspend the supply of bombs, the first linear drive 44 is started in the reverse direction to push the magazine 42 away from the discharge port to suspend the falling of the fire-extinguishing bomb 6. In this way, not only the stable supply of fire-extinguishing bombs 6 is ensured, but also the safety and reliability of the entire fire-fighting projectile gun are improved.

[0094] In an embodiment provided in the present disclosure, a plurality of buffer plates 45 are provided in the ammunition feeding bin 43 , and the buffer plates 45 are respectively arranged on two side walls of the ammunition feeding bin 43 .

[0095] The fire extinguishing bomb 6 falls vertically when it falls, and based on the existence of the buffer plate 45, the falling speed of the fire extinguishing bomb 6 in the bomb supply chamber 43 can be effectively slowed down, so that the fire extinguishing bomb 6 enters the distributing device 5 in a stable state.

[0096] 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.

[0097] Furthermore, along the height direction of the ammunition supply bin 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 in the ammunition supply bin 43 at a stable speed and posture, avoiding damage to the fire extinguishing bomb 6.

[0098] 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, and the fire extinguishing bomb 6 can be bounced in opposite directions. In this way, the fire extinguishing bomb 6 can gradually fall from the left and right into the arc groove 511, which can greatly slow down the falling speed of the fire extinguishing bomb 6, reduce potential energy, and reduce vibration and noise.

[0099] In one embodiment provided by the present disclosure, the contact surface of the buffer plate 45 is configured as an arc surface. Compared with a flat contact surface, the arc surface 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 arc surface design can provide a more uniform and stable buffering force, thereby more effectively slowing down 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 supply chamber 43 or the material distribution device 5.

[0100] 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 projection gun machine, but also can extend the service life of the bullet feeding device 4.

[0101] In practical applications, the design of the arc-surface buffer plate 45 can be applied to the two side walls of the magazine 43 and other parts that need to buffer the falling speed of the fire-extinguishing bomb 6. By properly configuring the number and position of the buffer plates 45, the falling speed of the fire-extinguishing bomb 6 can be accurately controlled to ensure the efficient and stable operation of the fire-fighting projectile gun.

[0102] Specifically, the buffer plate 45 is configured as a rubber plate or a polyurethane plate.

[0103] The rubber sheet is used as the buffer sheet 45. Based on the elastic characteristics of the rubber sheet, it can provide sufficient buffering force when the fire extinguishing bomb 6 falls, reduce collision and vibration, and thus reduce damage to the fire extinguishing bomb 6. At the same time, because the rubber sheet has good wear resistance, it can maintain stable performance during long-term use and reduce performance degradation caused by wear.

[0104] 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 slow down the speed and impact force 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.

[0105] 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; and when a stronger corrosion resistance or a longer service life is required, a polyurethane sheet can be selected.

[0106] In one embodiment provided by the present disclosure, the ammunition storage bin 42 and the ammunition supply bin 43 are both tilted so that the axis of the fire extinguishing bomb 6 is parallel to the axis of the gun barrel 2. With this arrangement, when the fire extinguishing bomb 6 falls under its own gravity, it can roll or slide along the inclined surface of the bin body, so that the axis of the fire extinguishing bomb 6 is parallel to the axis of the gun barrel 2. In this way, when the fire extinguishing bomb 6 is pushed or loaded into the gun barrel 2, it can ensure that the axis of the fire extinguishing bomb 6 is consistent with the axis of the gun barrel 2, thereby avoiding problems such as deviation or jamming during the firing process, and helping the fire extinguishing bomb 6 to be loaded smoothly.

[0107] In the present disclosure, a partition is provided in the magazine 42 to separate the magazine 42 into two chambers; wherein the size of each chamber is set to enable only the fire extinguishing bomb 6 to be dropped in the same posture. By dividing into two chambers, the size of each chamber is precisely designed to ensure that the fire extinguishing bomb 6 therein has the same posture when dropped, thereby ensuring the working efficiency and effect of the fire-fighting projectile machine.

[0108] At the same time, based on the size design of the chamber, the fire extinguishing bombs 6 are prevented from interfering with and colliding with each other in the bomb storage bin 42, reducing the possibility of mis-casting. At the same time, the orderly storage also helps the operator to more quickly identify and use the fire extinguishing bombs 6. The two independent chambers can store different types of fire extinguishing bombs 6 or spare fire extinguishing bombs 6 to meet different fire extinguishing needs.

[0109] 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 the fire extinguishing bomb 6 for solid combustion, while the other chamber stores the fire extinguishing bomb 6 for liquid or gas combustion.

[0110] Of course, it can also be that one chamber can store the fire extinguishing bomb 6 being used, and another chamber is used as standby storage. When the fire extinguishing bomb 6 in the main chamber is exhausted, it can be quickly switched to the standby chamber to ensure the continuous work of the fire-fighting projection gun machine.

[0111] The separated chambers facilitate the maintenance and management of the fire extinguishing bombs 6. The operator 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 projection gun machine.

[0112] 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 smooth rod, which is inserted in the through hole, and both ends of the smooth 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.

[0113] The threaded hole allows the screw to be inserted and cooperate with the threads inside the nut seat. When the screw rotates, the positioning block 46 will move along the axial direction of the screw due to the interaction with the threads. The polished rod can improve the stability of the positioning block 46 when it moves in a straight line, preventing it from rotating or other unexpected movements.

[0114] Specifically, one end of the screw is rotatably connected to the positioning plate 41 through the first bearing, and the other end is connected to the nut seat. The screw serves as a transmission element, and its rotation is converted into a linear motion of the positioning block 46. The first motor is arranged on the positioning plate 41, and its output shaft is transmission-connected to the screw. When the motor rotates, it drives the screw to rotate together, thereby driving the positioning block 46 to move on the screw.

[0115] When the position of the magazine 42 needs to be adjusted, the first motor is started, and its output shaft drives the screw to rotate. The rotation of the screw is converted into the linear motion of the positioning block 46 through the nut. The positioning block 46 moves on the screw, thereby driving the magazine 42 connected thereto to move linearly. Based on the cooperation between the screw and the positioning block 46, and the transmission relationship between the screw and the nut, the stability and accuracy of the movement process of the magazine 42 can be guaranteed.

[0116] In an embodiment provided in the present disclosure, the magazine 42 and the first linear drive member 44 are both configured in two groups, and the magazine 42 is respectively arranged on both sides of the discharge port; the first linear drive member 44 is correspondingly connected to the magazine 42.

[0117] By providing a magazine 42 on each side of the discharge port, it can be ensured that during the shooting process of the gun barrel 2, when one magazine 42 is feeding, the other magazine 42 has already prepared the next fire extinguishing bomb 6, thereby greatly reducing the waiting time for feeding and improving the feeding efficiency. Since the two magazines 42 alternately feed the bullets, there is almost no interruption in the feeding process, thereby enhancing the continuity of the shooting.

[0118] 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.

[0119] In an embodiment provided in 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 .

[0120] The limit switch is used to detect whether the magazine 42 reaches a preset limit position, which may include a maximum and a minimum moving distance of the magazine 42 to ensure that the magazine 42 moves within a safe range.

[0121] The controller is the control hub of the fire-fighting projectile machine, which is 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.

[0122] When the controller receives the signal from the limit switch, it sends a command to the first linear drive 44, requiring it to stop moving or change the direction of movement or reduce the speed of movement, so as to prevent the magazine 42 from exceeding its safe range of movement, thereby avoiding equipment damage or personal injury.

[0123] In practical applications, the setting of the limit switch can be adjusted according to the specific equipment requirements. For example, a limit switch can be set at the maximum and minimum movement positions of the magazine 42 to ensure that the magazine 42 does not exceed these positions during movement. In addition, additional limit switches can be set at certain key positions of the magazine 42 to provide more precise position control and protection.

[0124] According to a specific embodiment of the present disclosure, a material distribution device 5 for a fire-fighting projection cannon is provided, wherein: Figures 1 to 7 as well as Fig.10 One specific embodiment is shown.

[0125] See also Figures 1 to 7 as well as Fig.10 As shown, the material distribution device 5 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 will not deviate from the predetermined path during transportation. The front end of the arc groove 511 is sealed and connected to the bearing seat 56, and the rear end is sealed and connected to the sealing seat 52 to ensure that the airflow will not leak during transportation and ensure the pressure of the gas.

[0126] One end of the gas storage pipe 54 is connected to the pneumatic device 3, and the other end is connected to the sealing seat 52 through the control pipe 57; the control pipe 57 is provided with a control valve 58 to control the on and off of the airflow; the moving end of the pushing member 55 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 511 to approach or move away from the sealing seat 52. When the fire extinguishing bomb 6 is pushed to the vicinity of the sealing seat 52, the pushing member 55 will push the gun barrel 2 to move along the arc groove 511, so that the gun barrel 2 approaches or moves away from the sealing seat 52, so as to accurately deliver the fire extinguishing bomb 6 into the gun barrel 2.

[0127] When the gun barrel 2 abuts the sealing seat 52, the fire extinguishing bomb 6 has been smoothly pushed into the gun 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 pushes the fire extinguishing bomb 6 to eject from the chamber, so that it flies and falls into the target position to participate in the fire extinguishing work. After the ejection of the fire extinguishing bomb 6 is completed, the pushing member 55 moves the gun barrel 2 away from the sealing seat 52 and returns to the initial position to prepare for the next delivery.

[0128] The design of the material distribution device 5 makes the conveying process of the fire extinguishing bomb 6 more automated, efficient and safe. By accurately controlling the on and off of the airflow and the movement of the gun barrel 2, it can ensure that the fire extinguishing bomb 6 is accurately ejected, providing a reliable guarantee for the shooting of the fire-fighting projectile gun machine.

[0129] In one embodiment provided by the present disclosure, the pushing member 55 includes a clamp 551 and a linear module 552, and 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 the fire-fighting projection gun, the linear module 552 is connected to the barrel 2 through the clamp 551. When the linear module 552 is activated, it pushes the barrel 2 to move in the arc groove 511, realizing the automatic loading of the fire-extinguishing bomb 6.

[0130] When it is necessary to deliver the fire extinguishing bomb 6 from the magazine 42 into the gun barrel 2, the control system will send a command to the linear module 552. After receiving the command, the linear module 552 will start the motor and push the gun barrel 2 to move in the arc groove 511 through the cooperation of the guide rail and the positioning block 46. Due to the tight connection of the hoop 551, the gun barrel 2 can maintain a stable posture during the movement, ensuring that the fire extinguishing bomb 6 can accurately enter the gun barrel 2. When the gun barrel 2 moves to the appropriate position, the linear module 552 stops moving. At this time, the fire extinguishing bomb 6 has been successfully loaded and the shooting operation can be performed.

[0131] 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.

[0132] 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.

[0133] In an embodiment provided by the present disclosure, a second bearing for sleeved on the gun barrel 2 is provided on the bearing seat 56, and lubricating oil is provided in the second bearing. The second bearing provides a stable support point for the gun barrel 2, ensuring that the gun barrel 2 can be kept in the correct position during the movement, and preventing it from deflecting or shaking.

[0134] The gun barrel 2 is inserted into the second bearing, which helps to reduce the resistance of the gun barrel 2 when it moves, making it easier to be pushed by the pusher 55. During the movement of the gun barrel 2, a certain amount of heat will be generated due to friction. The lubricating oil can absorb and take away this heat, play a cooling role, and prevent the gun barrel 2 from overheating. The lubricating oil can also form a protective film on the surface of the gun barrel 2 to prevent it from contacting with moisture and oxygen in the environment, thereby reducing the risk of rust.

[0135] In addition, the lubricating oil can also form a lubricating film between the barrel 2 and the second bearing, further reducing the friction coefficient, allowing the barrel 2 to move more smoothly in the bearing seat 56, so the conveying efficiency of the entire material distribution device 5 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.

[0136] 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.

[0137] Specifically, the sealing ring is made of elastic materials, such as rubber, silicone or plastic, etc. These materials 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 according to actual needs.

[0138] 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 to ensure airtightness.

[0139] 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, so that a pressure difference can be formed between the sealing seat 52 and the barrel 2, thereby ensuring that the gas can flow out of the barrel 2 more smoothly, rather than backflow or leakage. Due to the small inner diameter of the gas outlet, the fluid will produce a certain pressure loss when passing through, but this loss helps to ensure the flow stability and directionality of the fluid in the pipeline, so that the high-pressure gas can push the fire extinguishing bomb 6 to move smoothly along the target position.

[0140] The inner diameter of the air outlet is smaller than the inner diameter of the gun barrel 2, which helps to improve the fluidity and concentration of the fluid. However, it should be noted 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 when the fluid passes through, thereby affecting the spraying ability and fire extinguishing effect of the water cannon. Therefore, when designing, it is necessary to reasonably determine the inner diameter of the air outlet according to specific usage requirements and environmental conditions.

[0141] In one embodiment provided in the present disclosure, the gas storage pipe 54 is C-shaped. The C-shaped gas storage pipe 54 can make more efficient use of space, thereby reducing the overall volume and weight. In addition, based on the shape design of the gas storage pipe 54, better structural strength and stability can also be provided. In some applications, such as fire extinguishing systems, the gas storage pipe 54 needs to withstand a certain pressure. The C-shaped design can increase the pressure resistance and stability of the gas storage pipe 54, ensuring that it will not be damaged by external factors during use.

[0142] In one embodiment provided by the present disclosure, the material distribution device 5 further includes an arc plate 59, which is connected to the gas storage pipe 54 and is tilted toward the top of the control valve 58. The arc plate 59 can cover and protect the control valve 58 to a certain extent, and at the same time, such a setting also has a certain aesthetic effect.

[0143] 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.

[0144] See also 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.

[0145] The driving wheel 82 is formed into a tooth shape that matches the sector gear 81, thereby ensuring the meshing stability with the sector gear 81, so that it can still maintain a stable transmission effect under the condition of heavy load or high speed. The first driver 83 is fixedly arranged on the body 1, and the driving wheel 82 is coaxially arranged on the output shaft of the first driver 83, and the driving wheel 82 is meshed with the sector gear 81.

[0146] Through the above technical solution, when the angle and height of the gun carriage 111 need to be adjusted, the first driver 83 is started to drive the driving wheel 82 to rotate, and the rotation of the driving wheel 82 drives the sector gear 81 to rotate. Since the sector gear 81 is connected to the gun carriage 111, the gun carriage 111 will also move accordingly. By controlling the output speed and direction of the first driver 83, the angle and height of the gun carriage 111 can be accurately adjusted, thereby achieving accurate aiming and projection of the gun barrel 2. In addition, the lifting device 8 has a compact structure, high transmission efficiency, a large adjustment range and high accuracy.

[0147] In an embodiment provided by the present disclosure, the sector gears 81 are configured as two groups and are spaced apart, and the driving wheels 82 are configured as two groups that mesh with the sector gears 81 one by one. The output torque can be significantly increased by the cooperation of the two groups of sector gears 81 and the driving wheels 82. When one group of gears is in operation, the other group can be used as a backup or auxiliary to reduce the risk of system failure due to failure of a single component. In this way, it can be ensured that the gun barrel 2 has higher accuracy and stability when adjusting the angle and height. Especially in dealing with large fires or emergency situations that require rapid response, it can ensure that the fire-fighting projection gun machine can quickly and accurately locate the source of the fire and effectively carry out fire-fighting operations.

[0148] In an embodiment provided by the present disclosure, two sector gears 81 are both arranged on the connecting rod shaft 84, and both ends of the connecting rod shaft 84 are connected to the machine body 1 through the third bearing 87. The sector gear 81 is installed on the connecting rod shaft 84 and connected to the machine body 1 through the connecting rod shaft 84, so that the sector gear 81 can remain stable when rotating and is not prone to deviation or shaking.

[0149] The third bearing 87 can withstand greater radial and axial loads, ensuring the stability of the connecting rod shaft 84 when rotating at high speed or bearing greater torque, and further enhancing the connection reliability between the connecting rod shaft 84 and the body 1.

[0150] When the first driver 83 drives the driving wheel 82 to rotate, the driving wheel 82 meshes with the sector gear 81, driving the sector gear 81 and the connecting rod shaft 84 to rotate together. Since both ends of the connecting rod shaft 84 are connected to the body 1 through bearings, the sector gear 81 can remain stable during rotation. At the same time, since the axis of the sector gear 81 is horizontally arranged, the rotation of the sector gear 81 will drive the gun carriage 111 to perform pitch motion, thereby adjusting the angle and height of the gun barrel 2.

[0151] When selecting the third bearing 87, it is necessary to comprehensively consider factors such as the diameter, rotation speed, and load bearing of the connecting rod shaft 84. Ensure that the selected bearing can withstand various forces and moments generated by the connecting rod shaft 84 during operation. In this regard, those skilled in the art can flexibly configure it according to actual needs.

[0152] In an embodiment provided in the present disclosure, the lifting 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 respectively fixedly connected to the two sector gears 81 .

[0153] Based on the setting of the reinforcing rod 85, by connecting the two sector gears 81 at both ends thereof, a stable triangular structure can be formed, which can effectively resist external loads and torque, thereby increasing the structural strength of the entire lifting device 8. At the same time, the two sector gears 81 can also be synchronized during rotation to ensure the smooth movement of the gun carriage 111. Under the condition of heavy load or long-term operation, the sector gear 81 may be subjected to greater stress and deformation. The presence of the reinforcing rod 85 can share these stresses and deformations, thereby protecting the sector gear 81 from damage.

[0154] In the present disclosure, the sector gear 81 is provided with a weight-reducing groove 86. The design of the weight-reducing groove 86 can not only reduce the overall mass of the gear, but also reduce the inertia moment of the gear, reduce the driving force required when rotating at high speed or bearing a large load, thereby improving the transmission efficiency to a certain extent. In addition, the weight-reducing groove 86 can optimize the stress distribution of the gear and reduce the influence of stress concentration, thereby improving the fatigue strength and durability of the gear.

[0155] Furthermore, the width of the weight-reducing groove 86 gradually increases in the direction away from the axis of the sector gear 81, which can reduce the overall weight of the gear while meeting the structural strength requirements of the gear. Since the weight-reducing groove 86 can reduce the rotational inertia of the gear, it can reduce the useless power consumption of the gear during rotation. The design of gradually increasing the groove width can make the weight-reducing groove 86 generate less air resistance when the gear rotates, further reducing power consumption and improving transmission efficiency.

[0156] 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 faster dissipation of heat generated by the gear when it rotates at high speed, reducing the temperature of the gear and increasing its service life.

[0157] In the present disclosure, the axial tooth thickness of the driving wheel 82 is greater than the axial tooth thickness of the sector gear 81. Since the axial tooth thickness of the driving wheel 82 is greater, it can provide a larger contact area and more stable transmission when meshing with the sector gear 81. This can reduce vibration and noise caused by poor meshing and improve the stability and reliability of gear transmission.

[0158] 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.

[0159] In an embodiment provided by the present disclosure, the first driver 83 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 82, which can convert the high-speed and low-torque output of the motor into a low-speed and high-torque output, which helps to provide sufficient torque to drive the sector gear 81 and the gun carriage 111 to perform lifting movements. At the same time, the reducer can also reduce the impact and vibration caused by the motor directly driving the driving wheel 82.

[0160] When the motor is started, its output shaft drives the reducer to rotate. The reducer converts the high-speed and low-torque output of the motor into a low-speed and high-torque output, and drives the driving wheel 82 to rotate through its output shaft. The driving wheel 82 meshes with the sector gear 81, driving the sector gear 81 and the connecting rod shaft 84 to rotate together, thereby adjusting the position of the gun carriage 111.

[0161] According to a specific embodiment of the present disclosure, a lifting device 9 for a fire-fighting projection cannon is provided. Figures 1 to 3 as well as Figure 7 and Figure 8 One specific embodiment is shown.

[0162] See also Figures 1 to 3 as well as Figure 7 and Figure 8As shown, the lifting device 9 for the fire-fighting projection cannon includes at least three support mechanisms 91 that can be lifted and lowered in the vertical direction, and the movements of different support mechanisms 91 are independent of each other, so that the cannon can be supported at multiple points, and can be kept stable by adjusting the height even on uneven roads. The support mechanism 91 includes a positioning end and a linear telescopic end, the positioning end is fixedly connected to the loading plate 7, and a foot seat 93 is provided at the bottom of the linear telescopic end; the lifting device 9 also includes a crossbeam 92, and the two ends of the crossbeam 92 are respectively connected to the positioning ends of different support mechanisms 91, thereby forming a stable frame structure. Not only can the stability of the entire lifting device 9 be enhanced, but also the relative displacement of the support mechanism 91 can be prevented during the lifting process.

[0163] Through the above technical solution, the lifting device 9 can provide stable support on various terrains through the connection of multiple independently adjustable support mechanisms 91 and crossbeams 92. Since the movements of different support mechanisms 91 are independent of each other, the height of each support mechanism 91 can be adjusted individually according to the actual terrain conditions to achieve the best support effect, thereby adapting to different terrains and aiming requirements, having good flexibility and applicability, and allowing the fire-fighting projectile machine to work stably on different road surfaces.

[0164] In one embodiment provided by the present disclosure, a ball socket is provided on the foot 93; a ball head 95 adapted to the ball socket is provided at the bottom of the linear telescopic end, and the ball head 95 is embedded in the ball socket. The foot 93 is the part of the lifting device 9 that contacts the ground and is responsible for supporting the entire device. The ball socket provided on the foot 93 is usually a groove that accounts for 2 / 3 of the sphere, and the spherical volume of the groove is at least greater than 3 / 5 of the entire sphere. In this way, the ball head 95 can rotate and tilt to a certain extent.

[0165] 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, so that the lifting device 9 can adapt to different terrains and conditions, ensuring that the fire-fighting projection cannon can always remain stable.

[0166] When the lifting device 9 is placed on uneven terrain, the pressure and angle of each support mechanism 91 will be different due to the change of ground height and angle. At this time, the matching design of the ball socket and the ball head 95 allows the linear telescopic end to be adaptively adjusted according to the actual situation of the ground.

[0167] Specifically, the ball head 95 can rotate and tilt in the ball socket, thereby ensuring that the linear telescopic end always remains vertical or nearly vertical to the ground, providing stable support for the lifting device 9, which is particularly suitable for fire-fighting projectile guns that need to operate in complex terrain and conditions. Whether on rugged mountain roads, muddy wetlands or uneven urban ground, this lifting device 9 can provide stable support for the gun, ensuring that it can accurately and efficiently perform fire-fighting tasks.

[0168] 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; a plurality of hydraulic cylinders are respectively connected to a hydraulic station through oil pipes; and the hydraulic station is communicatively connected to a controller.

[0169] The hydraulic cylinder uses the pressure of hydraulic oil to generate thrust or pull to control its own lifting and lowering. The footrest is set at the end of the hydraulic cylinder to increase the contact area with the ground, thereby improving the stability of the support. Multiple hydraulic cylinders are connected to the hydraulic station through oil pipes. The hydraulic station 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 lifting speed and position of each hydraulic cylinder can be accurately controlled, thereby achieving precise adjustment of the gun machine.

[0170] The controller can adjust the parameters of the hydraulic station in real time according to the preset program or the operator's 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.

[0171] Among them, the footrests are usually made of wear-resistant and non-slip materials to ensure reliable support in various terrains and conditions.

[0172] In the present disclosure, the foot 93 is configured as a rust-resistant metal seat. Metal materials usually have high strength and can withstand greater pressure and weight, ensuring that the lifting device 9 can remain stable in various working conditions. At the same time, the metal seat also has good thermal conductivity and can quickly transfer heat to the surrounding environment, reducing the risk of performance degradation or damage caused by high temperature. In this way, the fire-fighting projection cannon can effectively adapt to various working environments, such as humid, rainy, and even highly corrosive environments such as the seaside.

[0173] Furthermore, the support mechanism 91 is provided in four symmetrical groups; the positioning end of each support mechanism 91 is fixedly connected to the corner of the loading plate 7. In this way, the lifting device 9 can evenly distribute the load when bearing weight, avoiding damage or instability caused by excessive pressure on a certain part. In emergency situations such as fire rescue, the lifting device 9 can quickly and accurately adjust the position and angle of the gun machine to ensure the smooth progress of the rescue work.

[0174] In the present disclosure, a pad 94 is provided between the support mechanism 91 and the carrier plate 7. The pad 94 can provide a layer of buffer between the support mechanism 91 and the carrier plate 7 to reduce the direct stress caused by mechanical vibration, impact or adjustment process. In this way, the carrier plate 7 and the fire-fighting projectile machine installed thereon can be effectively protected from damage or excessive wear. In addition, the pad 94 can also increase the contact area between the support mechanism 91 and the carrier plate 7 to improve stability. Especially on uneven or inclined ground, the pad 94 can ensure stable contact between the support mechanism 91 and the carrier plate 7 to prevent sliding or tilting.

[0175] Specifically, the pad 94 can be detachably disposed between the support mechanism 91 and the loading plate 7, so that it can be adjusted or replaced as needed to adapt to different working environments and requirements. For example, when the height or angle of the fire-fighting projection cannon needs to be adjusted, it can be achieved by increasing or decreasing the number or thickness of the pads 94.

[0176] The pad 94 can be configured as a rubber pad 94, a metal pad 94 or a composite pad 94. The rubber pad 94 has good cushioning and anti-skid properties, and is suitable for occasions where vibration and impact need to be reduced. The metal pad 94 has high strength and wear resistance, and is suitable for occasions where greater pressure and friction need to be withstood. The composite pad 94 also has good cushioning, anti-skid and wear resistance. For the type of pad 94, those skilled in the art can flexibly select it according to the application environment.

[0177] According to a specific embodiment of the present disclosure, a positioning device for a fire-fighting projection cannon is provided, wherein: Figures 4 to 6 One specific embodiment is shown.

[0178] See also Figures 4 to 6 As shown, the positioning device for a fire-fighting projectile cannon comprises: a worm wheel, one end of which is fixedly connected to the machine body 1, that is, the rotation center of the machine body 1 coincides with the axis of the worm wheel; the other end of the worm wheel is rotatably connected to the loading plate 7. A worm is rotatably arranged on the loading plate 7 and meshed with the worm wheel; and a second motor 101, whose output shaft is drivingly connected to the worm; when the second motor 101 drives the worm to rotate, the worm wheel drives the machine body 1 to rotate with the axis of the worm wheel as the rotation center.

[0179] Through the above technical solution, when the second motor 101 is activated and drives the worm to rotate, the worm wheel will also start to rotate due to the meshing relationship between the worm and the worm wheel. Since one end of the worm wheel is fixedly connected to the body 1, the rotation of the worm wheel will drive the body 1 to rotate together, with the axis of the worm wheel as the rotation center. In this way, the position of the device such as the barrel 2 located on the body 1 can be adjusted. The worm gear mechanism has the characteristics of high transmission accuracy and large transmission ratio, making the rotation of the body 1 more accurate and reliable.

[0180] The positioning device uses the vertical direction as the rotation center, so that the machine body 1 can also rotate with the rotation center of the positioning device, so that the fire-fighting projection cannon can cover a wider area. In this way, no matter which direction the fire source is located, the cannon can quickly and accurately adjust the shooting angle, thereby improving its ability to cope with different fire source locations. When the location of the fire source changes, the fire-fighting projection cannon can also quickly adjust the shooting angle through the positioning device, shortening the response time and improving the fire-fighting efficiency.

[0181] 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 meshes with the worm at the opening.

[0182] The housing 102 is fixedly connected to the carrier plate 7, providing a closed environment for the worm gear, protecting the worm gear from dust, moisture and other potential pollutants, thereby extending its service life. The housing 102 is provided with an opening corresponding to the worm, which allows the worm to extend from the outside into the housing 102 and mesh with the worm gear, thereby ensuring the transmission relationship between the worm gear and the worm and making the entire device more neat and uniform in appearance. As a result, the worm gear can rotate smoothly when driven by the worm, thereby driving the fire-fighting projection cannon provided on the body 1 to rotate.

[0183] 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 on the worm and worm wheel.

[0184] 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 in the housing 102. The inner side of the fourth bearing 103 is fixedly connected to the worm gear, which can ensure that the worm gear rotates more smoothly and without shaking, thereby achieving precise control and stable operation of the fire-fighting projection cannon.

[0185] 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 can not only increase the service life of the positioning device, but also reduce noise and heat generated by friction.

[0186] In order to reduce friction and wear, a proper 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.

[0187] In an embodiment provided in the present disclosure, the positioning device includes an angle sensor for detecting the worm gear angle information, 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.

[0188] The angle sensor is installed on the positioning device to detect the rotation angle information of the worm gear. This sensor can measure the angle of rotation of the worm gear in real time and convert this information into electrical signals. The controller receives the electrical signals from the angle sensor and controls the motion state of the second motor 101 according to these signals.

[0189] Specifically, when the worm wheel rotates under the drive of the worm, the angle sensor detects the rotation angle information of the worm wheel 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 a corresponding control instruction according to the current rotation angle information of the worm wheel and the preset target rotation angle information (if necessary), and sends the generated control instruction to the second motor 101 to control the motion state of the motor. If the worm wheel has rotated past a predetermined angle, the controller may send an instruction to stop the motor from rotating; if the worm wheel has not reached the predetermined angle, the controller will continue to send instructions to allow the motor to continue rotating. Through real-time monitoring of the angle sensor and precise control of the controller, the positioning device can achieve precise rotation angle control of the worm wheel, thereby improving the positioning accuracy and shooting accuracy of the fire projection cannon.

[0190] 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 comprises a guide rail 104, a guide block and a second driver, the guide rail 104 is provided in at least two groups and is arranged in parallel on the mounting plate 105, 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.

[0191] 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 with the movement of the mounting plate 105 .

[0192] The guide rail 104 can ensure that the machine body 1 maintains a straight line or a predetermined path when moving, and the guide block is slidably connected to the guide rail 104 so that the guide block can move along the length direction of the guide rail 104. Since the top of the guide block is fixedly connected to the machine body 1, when the guide block moves, the machine body 1 will move accordingly.

[0193] Therefore, when the second driver is activated, the guide block is pushed to move along the guide rail 104. Since the guide block is fixedly connected to the body 1, the body 1 will also move with the movement of the guide block. In this way, the body 1 can slide on the mounting plate 105, which can further increase the adjustment range of the body 1, thereby improving the adaptability and flexibility of the fire-fighting projection cannon to the environment.

[0194] According to a specific embodiment of the present disclosure, a gun barrel 2 for a fire-fighting projectile gun machine is provided, wherein: Figures 14 to 16 One specific embodiment is shown.

[0195] See also 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, wherein 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.

[0196] By the above technical scheme, 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 barrel 2. Based on the design of the spoiler hole 23, when the fire extinguishing bomb 6 leaves the barrel 2, the gas can flow out rapidly through the spoiler hole 23, thereby reducing the pressure in the barrel 2, and helping the fire extinguishing bomb 6 to fly more stably. When the fire extinguishing bomb 6 leaves the barrel 2, the gas in the barrel 2 can produce high pressure because of sudden release. The spoiler hole 23 allows the gas to flow out rapidly, thereby reducing the pressure in the barrel 2, reducing the resistance to the fire extinguishing bomb 6. Due to the existence of the spoiler hole 23, the gas will produce certain disturbances 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 generated by the barrel 2 when firing.

[0197] 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 more evenly distributed 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.

[0198] The provision of a plurality of spoiler holes 23 can generate more disturbances, which are helpful to improve the flight trajectory and stability of the fire extinguishing bomb 6 .

[0199] 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.

[0200] 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 .

[0201] 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.

[0202] Specifically, in the exemplary embodiment of the present disclosure, the angle between the generatrix of the cone of the spoiler 22 and the axis is 30°, which can achieve a better spoiler effect. In other embodiments, the angle between the generatrix of the cone 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 obtain the best spoiler effect and projection performance.

[0203] In the present disclosure, the inner wall of the spoiler 22 is provided with a step, and a groove body adapted to the step is provided on the tube body 21. 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.

[0204] In the present disclosure, the spoiler 22 is provided with a threaded hole, and the screw is screwed into the threaded hole to press 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.

[0205] During maintenance, the screws can be easily screwed in or out by using tools such as a screwdriver, thereby installing or removing the spoiler 22.

[0206] In the present disclosure, the threaded holes are arranged in at least 3 groups and are evenly spaced around the circumference of the spoiler 22. By evenly distributing the threaded holes in the circumference of the spoiler 22, it is possible to ensure that the spoiler 22 is evenly supported and fixed at multiple points, which increases the structural stability of the spoiler 22 and makes it less likely to be deformed or damaged when subjected to external forces.

[0207] In the present disclosure, the material of the tube body 21 is chrome-molybdenum steel. In this way, even under high pressure, high temperature or high stress environment, the tube body 21 made of chrome-molybdenum steel can maintain its structural integrity and stability and is not prone to deformation or cracking.

[0208] 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.).

[0209] In the present disclosure, the material of the spoiler 22 is aluminum alloy. Aluminum alloy has the characteristics of low density and high strength, which enables the spoiler 22 to significantly reduce weight while maintaining sufficient strength. For the spoiler 22 that needs to be installed on a moving or rotating part, reducing weight can reduce energy consumption, improve response speed, and reduce the burden on the entire system.

[0210] 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, and certain acids and alkalis, so that the flow hood can maintain a long service life even in harsh environments and reduce the frequency of maintenance and replacement.

[0211] According to a specific embodiment of the present disclosure, a fire extinguishing bomb 6 for a fire-fighting projectile cannon is provided, wherein: Fig.17 One specific embodiment is shown.

[0212] See also Fig.17 As shown, the fire extinguishing bomb 6 for fire-fighting projection cannon includes a warhead 61, a middle water tank 62, a medicine tank 63, a chip tank 64 and a tail plate 65, which are all 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, a chip 66 is provided on the chip tank 64, 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 and inserted in the overflow hole.

[0213] 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 fired and hits the target, the liquid in the middle water tank 62 will flow out through the overflow hole of the bullet 61 to preliminarily cool and extinguish the fire source.

[0214] The agent bin 63 is connected to the chip bin 64 and is used to store fire extinguishing agents. Such agents can be dry powder, foam or other types of fire extinguishing agents, which can be selected according to different types of fire sources. The agents will be released when needed and work together with the liquid in the water bin 62 or alone to achieve a better fire extinguishing effect.

[0215] The chip compartment 64 is provided with a chip 66, which 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.

[0216] The tail plate 65 is located at the tail of the fire extinguishing bomb 6 and is connected to the chip compartment 64. The tail plate 65 not only plays a connecting and fixing role, but also transmits data with the chip 66 through a communication connection. This allows the status information of the fire extinguishing bomb 6 to be remotely read or controlled, thereby improving the efficiency and safety of the fire extinguishing operation.

[0217] 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 design of the overflow hole can be used for filling liquid. When the filling operation is performed, 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 based on 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 and has a certain wind-breaking effect, it can help the fire extinguishing bomb 6 to fly smoothly.

[0218] When the fire extinguishing bomb 6 is fired 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.

[0219] Through the above technical solution, when the fire extinguishing bomb 6 is fired and hits the target, the overflow hole of the bullet 61 will open, and the liquid in the middle water tank 62 will flow out quickly. At the same time, the agent will be released, so as to work together or alone with the liquid in the middle 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.

[0220] In the present disclosure, the inner wall surface of the middle water bin 62 is provided with a strip groove 68 for installing a swirl plate, the strip groove 68 extends along the axial direction of the middle water bin 62, the swirl plate is embedded in the strip groove 68, and the width of the swirl plate is smaller than the radius of the middle water bin 62. This arrangement enables the swirl plate to change the direction and speed of the liquid, thereby forming a rotating flow in the middle water bin 62, which helps to enhance the kinetic energy of the liquid, promote the mixing of the fire extinguishing agent and water, and thus improve the fire extinguishing efficiency.

[0221] The strip grooves 68 extend along the axis of the middle water bin 62, so that the swirl plates can be evenly distributed along the length of the middle water bin 62, ensuring that the liquid can effectively rotate in the entire middle water bin 62, while also preventing the liquid from being too concentrated or too sparse in some areas.

[0222] The swirl plate is embedded in the strip groove 68, so that the swirl plate can be firmly fixed on the inner wall surface of the middle water tank 62, so that the position of the swirl plate can be kept stable and it will not move or fall off under the action of high-speed liquid. At the same time, since the width of the swirl plate is smaller than the radius of the middle water tank 62, it will not occupy too much space in the middle water tank 62, thereby ensuring the smooth flow of liquid.

[0223] By providing a swirl plate in the intermediate water bin 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 bin 63 better mixed, thereby improving the fire extinguishing effect.

[0224] In the present disclosure, the strip grooves 68 are provided in 2n strips, and the strip grooves 68 are symmetrically arranged in the middle water tank 62; wherein n is a natural number greater than or equal to 1.

[0225] The strip grooves 68 are symmetrically arranged in the middle water bin 62, so that the swirl plates are also symmetrically distributed, which helps to produce a more uniform and stable swirl flow, ensuring that the kinetic energy of the liquid is fully utilized in the entire middle water bin 62. As the number of swirl plates increases (by increasing the number of strip grooves 68), the water will produce a stronger swirl effect when passing through these swirl plates, which helps to enhance the kinetic energy of the liquid and promote more uniform mixing of the fire extinguishing agent and water, thereby improving the fire extinguishing efficiency.

[0226] 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 requirements to obtain the best fire extinguishing effect.

[0227] The symmetrical strip grooves 68 and the swirl plate distribution help maintain the structural stability of the middle water tank 62. Under the action of high-speed liquid and fire extinguishing agent, the middle water tank 62 needs to have a certain pressure resistance. The symmetrical design can ensure that the middle water tank 62 can be evenly distributed when subjected to stress, reducing the risk of stress concentration and damage.

[0228] In an embodiment provided by the present disclosure, the head plug 67 is formed into a pointed shape that matches the tip profile of the bullet 61, so as to have a wind-breaking effect. The pointed shape of the head plug 67 perfectly matches the tip profile of the bullet 61, which can ensure the accuracy and stability during the manufacturing and assembly process of the fire extinguishing bomb 6. At the same time, due to the close fit between the two, the air resistance can be further reduced, and the projection distance and accuracy of the fire extinguishing bomb 6 can be improved.

[0229] The pointed shape of the head plug 67 has a wind-breaking effect during the flight of the fire-extinguishing bomb 6. When the fire-extinguishing bomb 6 flies in the air, it will encounter the influence of air resistance. The pointed head plug 67 can effectively cut and disperse the air flow, reducing the influence of air resistance on the flight trajectory of the fire-extinguishing bomb 6. This wind-breaking effect not only improves the flight speed and stability of the fire-extinguishing bomb 6, but also helps to ensure that the fire-extinguishing bomb 6 can accurately reach the target position.

[0230] Before the fire extinguishing bomb 6 is projected, the head plug 67 must be firmly sealed overflow hole to prevent moisture from leaking during flight. Once the fire extinguishing bomb 6 arrives at the target position 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.

[0231] In the present disclosure, the head plug 67 includes a plug-in section and a cover section integrally formed therewith, the plug-in section is formed into a structure adapted to the overflow hole so as to be press-fitted into the overflow hole; the cover section is fitted to the end face of the bullet 61. The plug-in section is tightly and stably pressed into the overflow hole, which can effectively prevent water or fire extinguishing agent from leaking from the overflow hole during the projection process, thereby ensuring the effectiveness of the fire extinguishing bomb 6. The cover section is fitted to the end face of the bullet 61, which not only enhances the connection stability between the head plug 67 and the bullet 61, but also plays a role in sealing and protection.

[0232] Since the plug section of the head plug 67 is compatible with the overflow hole, the installation process is usually relatively simple. At the same time, since the cover pressing section is closely fitted with the end surface of the bullet head 61, certain skills and tools are required when removing the head plug 67, which not only ensures that the head plug 67 is easy to install, but also prevents safety hazards caused by random removal by non-professionals.

[0233] In the present disclosure, the contact surfaces of the head plug 67 and the bullet 61 are both provided with sealant, so as to fill the sealed joint, rely on temperature changes, solvent volatilization, chemical cross-linking, etc. to stably bond with the substrate, and gradually shape into a plastic solid, viscoelastic elastic sealing material. Therefore, when the contact surfaces of the head plug 67 and the bullet 61 are coated with sealant, a stable sealing connection can be ensured between the two to prevent liquid or gas leakage.

[0234] In the present disclosure, the chip compartment 64 is provided with a connection hole for installing the medicine compartment 63 and a chip 66 slot for installing the chip 66; the end of the medicine compartment 63 is screwed to the connection hole to ensure a stable 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 through a first fastener. Through the first fastener (such as a screw, a buckle, etc.), the chip 66 is firmly connected to the chip 66 slot to prevent loosening or falling off due to vibration or impact. The chip 66 slot is used to place the chip 66 and allow the chip 66 to be electrically connected to the chip compartment 64.

[0235] In the present disclosure, the tail plate 65 includes a substrate 651 made of plastic material and a plurality of copper rings 652 with 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; the chip 66 is communicatively connected to different copper rings 652.

[0236] The copper ring 652 is designed to have different diameters, which can represent different electrical channels or signal lines, thereby realizing different communication or control functions, thereby adapting to different electrical connection requirements. The copper ring 652 is embedded in the ring groove on the substrate 651, which can ensure the stability and position accuracy of the copper ring 652. After the copper ring 652 is embedded in the ring groove, a part of the substrate 651 is melted to completely cover the copper ring 652, ensuring a tight connection between the copper ring 652 and the substrate 651, and providing additional protection and stability.

[0237] 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.
