Description

Technical Field

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

[0002] A fire-fighting cannon machine is an efficient fire-extinguishing device that can spray fire-extinguishing agents (such as water, foam mixture, or dry powder, etc.) onto the fire scene at a very high speed, forming a powerful jet flow, thereby quickly reducing the fire intensity, controlling the fire source, and ultimately achieving fire extinguishing.

[0003] In the utility model patent with the publication number CN215136280U, a large-flow mobile remote-control fire-fighting cannon extinguishing component is disclosed, which includes a pickup truck mobile carrier, a water collector, and a fire-fighting cannon. The water collector is provided with several fire-extinguishing medium inlets with different specifications and a fire-extinguishing medium outlet, and is integrally fixed on the pickup truck mobile carrier and can move with it; the fire-fighting cannon is hermetically connected to the fire-extinguishing medium outlet of the water collector and is placed on the pickup truck mobile carrier together; the fire-fighting cannon includes a cannon body, a cannon head, a control motor, and a horizontal pitch and yaw mechanism connected to the control motor and the cannon body. The cannon body has a large rotary structure, its head end is hermetically connected to the cannon head, and its tail end is hermetically connected to the fire-extinguishing medium outlet of the water collector. The fire-fighting cannon can adjust the spraying angle and direction of its cannon head through the control motor controlling the horizontal pitch and yaw mechanism.

[0004] During the process of dealing with major and extremely large fires, the large-flow mobile remote-control fire-fighting cannon extinguishing component first drives the pickup truck mobile carrier to quickly reach the fire site for fire extinguishing, selects the best fire extinguishing position to park, then uses a fire hose to connect the water inlet of the water collector and the water outlet of the water supply pipeline of the rear-field fire truck, operates the rear-field fire truck to supply water to the front-field extinguishing component until the rated working pressure, and adjusts the spraying angle and direction of the cannon head to the best fire extinguishing position through the control motor controlling the horizontal pitch and yaw mechanism for accurate and rapid fire extinguishing.

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

[0006] Furthermore, during the filling of the fire extinguishing bomb, the operation is extremely inconvenient, making it difficult to perform continuous and efficient bomb filling. Additionally, when the fire extinguishing bomb is falling, it is extremely easy to be scratched, resulting in the structure of the fire extinguishing bomb being affected even before it is launched. When the fire extinguishing bomb is launched, due to the structure of the gun barrel and the form of the clamping seat rollers, not only will the structure of the gun barrel change, but also the overall position of the pickup truck will shift. Manual secondary adjustment of the position of the gun mechanism is required, and the operation is rather cumbersome. This not only affects the continuity of the fire extinguishing bomb launch but also greatly reduces the accuracy of the landing position of the fire extinguishing bomb, affecting the fire extinguishing process.

[0007] In addition, in this case, the position adjustment of the gun barrel depends on the position of the pickup truck. Therefore, only a rough adjustment of the gun barrel position can be made, and precise adjustment is impossible, further reducing the accuracy and applicability of the projection position of the shell.

[0008] Based on the structure of the gun barrel, the shell is greatly affected by the airflow during launch and is prone to rotation or roll during flight, making it difficult to accurately land along the predetermined route. Therefore, due to the superposition of different factors, the actual landing position of the shell is unpredictable relative to the target fire extinguishing position, causing technical obstacles in fire fighting work.

[0009] Therefore, in view of the problems existing in the current gun mechanism, such as poor accuracy of the projection direction of the fire extinguishing bomb, unstable projection range of the fire extinguishing bomb, easy deviation and shaking of the gun barrel, difficulty in efficiently extinguishing the fire point, and poor environmental adaptability, a more reasonable technical solution is still needed to solve the problems existing in the prior art. Utility Model Content

[0010] The purpose of the present utility model is to provide a lifting device for a fire fighting projection gun mechanism to solve the technical problems of poor environmental adaptability, low applicability, limited application range, and unstable support of the gun mechanism in the background technology.

[0011] To achieve the above object, the present utility model provides a jacking device for a fire fighting projection gun mechanism, including at least three support mechanisms that can be lifted and lowered in the vertical direction, and the movements between different support mechanisms are independent of each other; each support mechanism includes a positioning end and a linear telescopic end, the positioning end is fixedly connected to the load-bearing plate, and a footrest is provided at the bottom of the linear telescopic end; the lifting device further includes a cross beam, and both ends of the cross beam are respectively connected to the positioning ends of different support mechanisms.

[0012] Optionally, a ball socket is provided on the footrest; a ball head adapted to the ball socket is provided at the bottom of the linear telescopic end, and the ball head is embedded in the ball socket.

[0013] Optionally, the support mechanism is configured as a hydraulic cylinder, and a foot pad is provided at the end of the hydraulic cylinder; a plurality of hydraulic cylinders are respectively connected to a hydraulic station through oil pipes; the hydraulic station is communicatively connected to a controller.

[0014] Optionally, the footrest is configured as a rust-resistant metal seat.

[0015] Optionally, the support mechanism is configured into four groups arranged symmetrically; and the positioning ends of each support mechanism are fixedly connected to the corners of the load-carrying plate.

[0016] Optionally, a cushion plate is provided between the support mechanism and the load-carrying plate.

[0017] Through the above technical solutions, through the connection of multiple independently adjustable support mechanisms and crossbeams, the lifting device can provide stable support on various terrains. Since the movements between different support mechanisms are independent of each other, the height of each support mechanism can be adjusted individually according to the actual situation of the terrain to achieve the best support effect, thereby adapting to different terrains and aiming requirements, having good flexibility and applicability, and enabling the fire projection cannon machine to work stably on different road surfaces.

Detailed Embodiment

[0039] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0040] According to a specific embodiment of the present disclosure, a fire projection gun machine is provided, wherein Figures 1 to 17 one of the specific embodiments is shown.

[0041] Refer to Figures 1 to 17As shown in the figure, the fire projection cannon machine includes: a body 1; a gun barrel 2 having a borehole adapted to a fire extinguishing bomb 6; the gun barrel 2 is movably connected to a gun mount 111, and the gun mount 111 is connected to the body 1; a pneumatic device 3 provided on the body 1, and the pneumatic device 3 is used to convey high-pressure gas; a feeding device 4 provided on the body 1, and the feeding device 4 is used to export the fire extinguishing bombs 6 one by one; and a material distributing device having an arc-shaped groove 511 for defining the position of a single fire extinguishing bomb 6, and the axis of the arc-shaped groove 511 is parallel to the axis of the gun barrel 2; one end of the material distributing device communicates with the feeding device 4 to receive the fire extinguishing bombs 6 exported from the feeding device 4; the other end of the material distributing device communicates with the pneumatic device 3; the material distributing device further includes a pushing member 55, the fixed end of the pushing member 55 is connected to the gun mount 111, and its telescopic end is connected to the gun barrel 2, and the pushing member 55 is used to push the gun barrel 2 to move along the arc-shaped groove 511 and insert the fire extinguishing bomb 6 on the arc-shaped groove 511 into the borehole of the gun barrel 2; wherein, when the fire extinguishing bomb 6 is inserted into the gun barrel 2, the gun barrel 2 communicates with the pneumatic device 3; the pneumatic device 3 conveys high-pressure gas to shoot the fire extinguishing bomb 6 out of the borehole of the gun barrel 2.

[0042] The body 1 serves as the basic structure of the entire fire projection cannon machine, which can facilitate the installation of other components such as the gun barrel 2, the pneumatic device 3, the feeding device 4, and the material distributing device on the body 1 directly or indirectly. The gun mount 111 is the support 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 borehole adapted to the fire extinguishing bomb 6 for accommodating and firing the fire extinguishing bomb 6. The pneumatic device 3 is provided on the body 1 for conveying high-pressure gas.

[0043] The feeding device 4 is provided on the body 1 for exporting the fire extinguishing bombs 6 one by one. Through the design of the arc-shaped groove 511, the material distributing device can accurately define the position of the fire extinguishing bomb 6 to ensure that the fire extinguishing bomb 6 can be accurately pushed into the borehole of the gun barrel 2. The setting of the pneumatic device 3 enables the cannon machine to convey high-pressure gas, so as to shoot the fire extinguishing bomb 6 out of the gun barrel 2 at a relatively high speed and force. And this high-pressure launching ability can make the fire extinguishing bomb 6 be launched to a relatively long distance, so as to extinguish the fire at a long-distance fire point.

[0044] The working principle of the fire projection cannon is as follows: First, according to the location of the ignition point, the position of the entire fire projection cannon is adjusted so that the gun barrel 2 is aimed at the ignition point. The feeding device 4 sequentially conveys the fire extinguishing bombs 6 towards the material distributing device. When the fire extinguishing bomb 6 falls into the arc-shaped groove 511 of the material distributing device, the pushing member 55 pushes the gun barrel 2 towards 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, and the fire extinguishing bomb 6 is ejected from the gun barrel 2 by the impact force of the high-pressure gas gushing out instantaneously, so that it can be accurately released at the ignition point, thereby effectively extinguishing the fire source.

[0045] Based on the above technical solution, the steps of feeding, material distributing, pushing, and launching of the fire projection cannon can achieve automated or semi-automated operation, greatly shortening the preparation time and launching time, and improving the efficiency of dealing with fires. By combining the precise aiming at the fire source and the high-pressure launching ability, the fire projection cannon can quickly deliver the fire extinguishing bomb 6 to the fire source and effectively extinguish the fire, which can significantly improve the fire extinguishing efficiency and effect, providing strong support for dealing with fires.

[0046] In an embodiment provided by the present disclosure, the gun barrel 2 includes a barrel body 21 and a spoiler 22. The spoiler 22 is sleeved at one end of the barrel body 21 and fixedly connected to the barrel body 21. Wherein, the spoiler 22 is conical, its diameter gradually increases in the direction away from the barrel body 21, and the spoiler 22 is provided with spoiler holes 23. The spoiler holes 23 extend along the gas flow direction and penetrate through the spoiler 22. One end of the spoiler hole 23 is located on the outer wall of the spoiler 22, and the other end is located on the inner wall of the spoiler 22.

[0047] The design of the spoiler holes 23 on the spoiler 22 can guide the high-pressure gas to generate turbulence when passing through, which can improve the gas flow efficiency and the stability of the fire extinguishing bomb 6. The spoiler holes 23 extend along the gas flow direction, which can optimize the gas flow characteristics, reduce the turbulence and eddy current of the gas in the gun barrel 2, and improve the launching accuracy.

[0048] 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, enabling the fire extinguishing bomb 6 to obtain a higher speed and a farther range when launched.

[0049] In the present disclosure, the fire extinguishing bomb 6 includes a warhead 61, a medium water storage chamber 62, a chemical agent storage chamber 63, a chip storage chamber 64, and a tail plate 65 that are all coaxially arranged. Among them, both ends of the medium water storage chamber 62 are respectively connected to the warhead 61 and the chip storage chamber 64. That is to say, the medium water storage chamber 62 is located between the warhead 61 and the chip storage chamber 64 and is used to store water or other fire extinguishing liquids. The chemical agent storage chamber 63 is used to store fire extinguishing agents, and the agents can be dry powder, foam, or other types of fire extinguishing agents, which can be selected according to different types of fire sources.

[0050] Specifically, the chemical agent storage chamber 63 is connected to the chip storage chamber 64. A chip 66 is provided on the chip storage chamber 64, and the tail plate 65 is connected to the chip storage chamber 64 so that the chip 66 is communicatively connected to the tail plate 65. This 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 to 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 role in connection and fixation, but also conducts data transmission with the chip 66 through communication connection. This enables the status information of the fire extinguishing bomb 6 to be remotely read or controlled, improving the efficiency and safety of fire extinguishing operations.

[0051] Among them, an overflow hole is provided at the tip of the warhead 61, and a head plug 67 is hermetically inserted into the overflow hole. The design of the overflow hole can be used for filling liquids. During the filling operation, the liquid is poured from the overflow hole of the warhead 61. As the filling work continues, based on the oscillation of the liquid, bubbles or foam are generated on the liquid surface. Therefore, after the filling is completed, 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 voids, effectively eliminate bubbles, and fill the warhead 61 with liquid, which is beneficial for the fire extinguishing bomb 6 to fly smoothly along the launch trajectory and avoid disturbing the flight trajectory due to the shaking of the liquid inside. In addition, since the head plug 67 is sharp, it has a certain wind-breaking effect and can help the fire extinguishing bomb 6 fly smoothly.

[0052] When the fire extinguishing bomb 6 is launched and impacts the target, the liquid in the medium water storage chamber 62 will flow out through the overflow hole of the warhead 61. At the same time, the chemical agent will be released, so as to act together with or separately from the liquid in the medium water storage chamber 62 to achieve a better fire extinguishing effect.

[0053] When the fire extinguishing bomb 6 is launched and impacts the target, the overflow hole of the warhead 61 will open, and the liquid in the medium water storage chamber 62 will quickly flow out. At the same time, the chemical agent will be released, so as to act together with or separately from the liquid in the medium water storage chamber 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.

[0054] In the present disclosure, the material distributing device includes a receiving seat 51, a sealing seat 52, a gas storage pipe 54, and a pushing member 55. An arc-shaped groove 511 for defining the position of the fire extinguishing bomb 6 is provided on the receiving seat 51. The front end of the arc-shaped groove 511 is hermetically connected to a bearing seat 56, and the rear end is hermetically connected to the sealing seat 52. 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 a control pipe 57. A control valve 58 is provided on the control pipe 57 to control the on-off of the air flow. The moving end of the pushing member 55 is connected to the gun barrel 2, and the moving direction of this moving end is parallel to the axis direction of the gun barrel 2, so that the gun barrel 2 can move along the arc-shaped groove 511 to approach or move away from the sealing seat 52.

[0055] The arc-shaped groove 511 on the receiving seat 51 is used to define 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-shaped groove 511 enables the fire extinguishing bomb 6 to be accurately guided to the designated position of the arc-shaped groove 511 under the action of the feeding devices 4 on the left and right sides. The front end of the arc-shaped groove 511 is hermetically connected to the bearing seat 56, and the rear end is hermetically connected to the sealing seat 52. Such a design ensures the sealing performance of the arc-shaped groove 511, preventing gas leakage or the fire extinguishing bomb 6 from falling during the material distribution and pushing processes.

[0056] 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. A control valve 58 is provided on the control pipe 57 for controlling the on-off of the air flow. When the fire extinguishing bomb 6 is pushed to the bore of the gun barrel 2, the control valve 58 opens, and the high-pressure gas conveyed 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 out of the gun barrel 2.

[0057] The moving end of the pushing member 55 is connected to the gun barrel 2, and the moving direction of this moving end is parallel to the axis direction of the gun barrel 2. When the pushing member 55 moves, it can push the gun barrel 2 to move along the arc-shaped 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.

[0058] Through the design of the two groups of feeding devices 4 and the arc-shaped groove 511, efficient, stable, and continuous feeding of the fire extinguishing bomb 6 can be achieved, which is beneficial to reducing the waiting time and improving the fire extinguishing efficiency. Among them, the pushing member 55 ensures that the gun barrel 2 can accurately move along the arc-shaped groove 511, pushing the fire extinguishing bomb 6 into the bore of the gun barrel 2 to prepare for firing. By controlling the on-off of the air flow through the control valve 58, the safety during the firing process is guaranteed, avoiding accidents. The entire material distributing device is reasonably designed and has a stable structure, capable of working reliably in various environments and meeting the requirements of fire extinguishing.

[0059] In the present disclosure, the ammunition feeding device 4 includes: a positioning plate 41, which is provided with a blanking opening 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 blanking opening each time, and avoiding blockage or chaos that may be caused by the simultaneous falling of multiple fire extinguishing bombs 6.

[0060] A storage bin 42 is used for storing the fire extinguishing bombs 6; the storage bin 42 is movably connected to the positioning plate 41 through a positioning block 46, allowing fine adjustment of the position of the storage bin 42 on the positioning plate 41, so as to control the speed and timing of the fire extinguishing bombs 6 passing through the blanking opening. A feeding bin 43 is arranged below the positioning plate 41, and one end of the feeding bin 43 communicates with the blanking opening, and the other end communicates with an arc-shaped groove 511 on the material distributing device; and a first linear driving member 44, one end of which is connected to the positioning plate 41, and the other end is connected to the storage bin 42. The first linear driving member 44 is used to push the storage bin 42 closer to or away from the blanking opening, so that the fire extinguishing bombs 6 can fall into the feeding bin 43 under the action of gravity.

[0061] Specifically, when it is necessary to replenish the fire extinguishing bombs 6 into the feeding bin 43, the first linear driving member 44 pushes the storage bin 42 closer to the blanking opening until the fire extinguishing bombs 6 in the storage bin 42 are aligned with the blanking opening, so that the fire extinguishing bombs 6 naturally fall into the feeding bin 43 under the action of gravity; when the number of fire extinguishing bombs 6 in the feeding bin 43 is sufficient or it is necessary to pause the ammunition feeding, the first linear driving member 44 moves in the reverse direction, pushing the storage bin 42 away from the blanking opening and pausing the falling of the fire extinguishing bombs 6. Thus, a stable and continuous supply of the fire extinguishing bombs 6 is ensured.

[0062] In the present disclosure, the fire fighting projection gun machine further includes a lifting device 8, one end of the lifting device 8 is connected to the machine body 1, and the other end is connected to the gun mount 111 to adjust the elevation angle of the gun mount 111.

[0063] The elevation angle refers to the angle of the gun barrel 2 or the muzzle relative to the horizontal plane. During the fire fighting process, according to the height, distance and position of the fire source, it is necessary to adjust the elevation angle of the gun mount 111 to ensure that the fire extinguishing bombs 6 can be accurately shot at the target.

[0064] The lifting device 8 can be configured as 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 mount 111 and indirectly realizing the change of the position of the gun barrel 2. When it is necessary to increase the elevation angle of the gun mount 111, the lifting device 8 will extend or rise, raising the gun mount 111 relative to the machine body 1; conversely, when it is necessary to decrease the elevation angle, the lifting device 8 will shorten or descend, lowering the gun mount 111 to ensure that the fire extinguishing bombs 6 can be accurately shot at the target.

[0065] In the present disclosure, the fire projection cannon machine further includes a lifting device 9, and the lifting device 9 is connected to the machine body 1 through a loading platform; wherein, the lifting device 9 includes at least three support mechanisms 91 that can be lifted in the vertical direction, and the movements between different support mechanisms 91 are independent of each other.

[0066] The lifting device 9 is connected to the machine body 1 of the fire projection cannon machine through a 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 individually controlled to lift, so that the rotation angle of the gun barrel 2 can be adjusted according to different usage environments, thereby aiming at the target position and achieving the best fire extinguishing effect.

[0067] In the embodiment provided by the present disclosure, the fire projection cannon machine further includes a positioning device, the fixed end of the positioning device is connected to the loading platform, and the movable end is connected to the machine body 1 to drive the machine body 1 to rotate around the vertical direction as the rotation center.

[0068] The positioning device rotates around the vertical direction as the rotation center, so that the machine body 1 can rotate 360 degrees, enabling the fire projection cannon machine to cover a wider area. No matter in which direction the fire source is located, the cannon machine can quickly and accurately adjust the shooting angle, thereby improving its ability to respond to different fire source positions. When the position of the fire source changes, the fire projection cannon machine can also quickly adjust the shooting angle through the positioning device, shortening the response time and improving the fire extinguishing efficiency.

[0069] In complex environments such as high-rise buildings, forests, and large warehouses, the occurrence of fires is often unpredictable. By equipping a fire projection cannon machine with a positioning device, the fire source can be quickly located and extinguished, reducing the losses of fires to personnel and property. At the same time, the fire projection cannon is also applicable to some special occasions, such as offshore oil platforms, nuclear power plants and other high-risk areas, and has good practicability.

[0070] The fire projection cannon machine further includes a controller, and the controller is communicatively connected to the pneumatic device 3, the ammunition supply device 4 and the material distribution device to control the pneumatic device 3, the ammunition supply device 4 and the material distribution device to perform corresponding actions according to a preset program.

[0071] The controller integrates real-time information such as sensor data and fire scene images, and combines preset fire extinguishing strategies and operator instructions to form an intelligent control system. This system can achieve precise control of the fire projection cannon machine, ensuring that fire extinguishing operations can be carried out quickly and effectively in the fire scene. At the same time, the controller can also record and analyze the data during the fire extinguishing process, providing reference and basis for subsequent fire extinguishing work.

[0072] In the present disclosure, the jacking device 8, the lifting device 9, and the position adjustment device are also communicatively connected to the controller. Among them, the jacking device 8, the lifting device 9, and the position adjustment device are mainly used to drive the parts in the fire cannon that require fast and precise control of actions, such as the pitch angle of the gun barrel 2, the height of the gun barrel 2, and the position and attitude of the gun barrel 2 in the horizontal plane. The controller sends instructions to the pneumatic device 3 to adjust the attitude and angle of the fire cannon according to a preset sequence or in real time according to the fire scene, ensuring the accuracy and effect of projection.

[0073] It should be understood that for the term "and / or" appearing in this article, it is merely an association relationship describing associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, B exists alone, and A and B exist simultaneously.

[0074] According to a specific embodiment of the present disclosure, a feeding device 4 for a fire projection cannon is also provided. Figures 1 to 9 One specific embodiment is shown.

[0075] Refer to Figures 1 to 9 As shown, the feeding device 4 for the fire projection cannon includes: a positioning plate 41, which is provided with a blanking port for only a single fire extinguishing bomb 6 to pass through, ensuring that only one fire extinguishing bomb 6 can enter the feeding process through the blanking port each time, effectively avoiding blockage or chaos that may be caused by multiple fire extinguishing bombs 6 falling simultaneously.

[0076] A storage bin 42 for storing the fire extinguishing bombs 6; the storage bin 42 is movably connected to the positioning plate 41 through a positioning block 46, thereby realizing fine adjustment of the position of the storage bin 42 on the positioning plate 41, so as to control the speed and timing of the fire extinguishing bombs 6 passing through the blanking port.

[0077] A feeding bin 43 is arranged below the positioning plate 41, and one end of the feeding bin 43 communicates with the blanking port, and the other end communicates with an arc-shaped groove 511 on the material distribution device. When the fire extinguishing bomb 6 falls from the blanking port, it will directly enter the feeding bin 43 and enter the arc-shaped groove 511 of the material distribution device through the other end of the feeding bin 43.

[0078] The first linear drive 44 controls the fall of the fire extinguishing bomb 6 by pushing the ammunition storage bin 42 closer to or farther away from the blanking 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 ammunition storage bin 42. The first linear drive 44 is used to push the ammunition storage bin 42 closer to or farther away from the blanking port, so that the fire extinguishing bomb 6 can fall into the ammunition supply bin 43 under the action of gravity. When it is necessary to replenish the fire extinguishing bomb 6 into the ammunition supply bin 43, the first linear drive 44 pushes the ammunition storage bin 42 closer to the blanking 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 it is necessary to suspend the ammunition supply, the first linear drive 44 pushes the ammunition storage bin 42 away from the blanking port to suspend the fall of the fire extinguishing bomb 6.

[0079] In the initial state, the ammunition storage bin 42 is located at a position far from the blanking port to ensure that no fire extinguishing bomb 6 falls. When the fire projection cannon needs to launch the fire extinguishing bomb 6, the first linear drive 44 is activated to push the ammunition storage bin 42 to move along the lead screw towards the positioning plate 41 until the fire extinguishing bomb 6 in the ammunition storage bin 42 is aligned with the blanking port. Under the action of gravity, the fire extinguishing bomb 6 falls into the ammunition supply bin 43 through the blanking port. And the fire extinguishing bomb 6 in the ammunition supply bin 43 falls into the arc-shaped groove 511 of the material distribution device under the action of gravity or other conveying devices. The material distribution device guides the fire extinguishing bombs 6 one by one to the gun barrel 2 for launching preparation. When the fire extinguishing bomb 6 is in place or in other cases where it is necessary to suspend the ammunition supply, the first linear drive 44 is activated in the reverse direction to push the ammunition storage bin 42 away from the blanking port to suspend the fall of the fire extinguishing bomb 6. In this way, not only the stable supply of the fire extinguishing bomb 6 is ensured, but also the safety and reliability of the entire fire projection cannon are improved.

[0080] In an embodiment provided by the present disclosure, a plurality of buffer plates 45 are provided in the ammunition supply bin 43, and the buffer plates 45 are respectively arranged on both side walls of the ammunition supply bin 43.

[0081] When the fire extinguishing bomb 6 falls, it falls vertically. Due to the existence of the buffer plate 45, the falling speed of the fire extinguishing bomb 6 in the ammunition supply bin 43 can be effectively slowed down, so that the fire extinguishing bomb 6 enters the material distribution device in a stable state.

[0082] The fire extinguishing bomb 6 rolls freely in the ammunition supply bin 43. Due to the arrangement of the buffer plate 45, the collision between the fire extinguishing bomb 6 and the side wall of the ammunition supply bin 43 can be reduced, thereby protecting the integrity of the fire extinguishing bomb 6, and the potential energy when falling into the arc-shaped groove 511 can be effectively reduced, the impact can be reduced, and the noise can be reduced.

[0083] Further, along the height direction of the ammunition feeding bin 43, the buffer plates 45 on the two side walls are arranged in a staggered manner, so as to provide a more stable and effective buffering effect during the falling process of the fire extinguishing bomb 6, ensure that the fire extinguishing bomb 6 falls in the ammunition feeding bin 43 at a stable speed and posture, and avoid damage to the fire extinguishing bomb 6.

[0084] Specifically, during the falling process, the buffer plates 45 are arranged in a staggered manner on the two side walls, so that the fire extinguishing bomb 6 will be subjected to acting forces from different directions during the falling process, which can make the fire extinguishing bomb 6 fall towards the opposite direction. In this way, the fire extinguishing bomb 6 can gradually fall to the arc-shaped groove 511 one by one from left to right, which can greatly slow down the falling speed of the fire extinguishing bomb 6 and reduce the potential energy, and can reduce vibration and noise.

[0085] In an 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-shaped 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 ammunition feeding bin 43 or the material distribution device.

[0086] Since the arc-shaped contact surface can better fit the surface of the fire extinguishing bomb 6, the noise and vibration generated during the collision process 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 ammunition feeding device 4.

[0087] In practical applications, the design of the arc-shaped buffer plate 45 can be applied to the two side walls of the ammunition feeding bin 43 and other parts that need to buffer the falling speed of the fire extinguishing bomb 6. By reasonably configuring the number and position of the buffer plates 45, precise control of the falling speed of the fire extinguishing bomb 6 can be achieved, ensuring the efficient and stable operation of the fire fighting projection gun machine.

[0088] Specifically, the buffer plate 45 is configured as a rubber plate or a polyurethane plate.

[0089] Taking the rubber plate as the buffer plate 45, based on the elastic characteristics of the rubber plate, it can provide sufficient buffering force when the fire extinguishing bomb 6 falls, reduce collisions and vibrations, thereby reducing damage to the fire extinguishing bomb 6. At the same time, due to the good wear resistance of the rubber plate, it can maintain stable performance during long-term use and reduce performance degradation caused by wear.

[0090] Taking the polyurethane plate as the buffer plate 45, similarly based on the material characteristics of the polyurethane plate, it has good buffering performance and can effectively slow down the falling speed and impact force of the fire extinguishing bomb 6 when it falls. The polyurethane plate has good resistance to chemical corrosion and can maintain stable performance under various environmental conditions.

[0091] In practical applications, a rubber plate or a polyurethane plate can be selected as the material of the buffer plate 45 according to the specific usage environment and requirements. For example, in cases where higher buffering effect and wear resistance are required, a rubber plate can be selected; while in cases where stronger corrosion resistance or longer service life is needed, a polyurethane plate can be chosen.

[0092] In an embodiment provided by the present disclosure, both the ammunition storage chamber 42 and the ammunition feeding chamber 43 are inclined, such 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 chamber body, making the axis of the fire extinguishing bomb 6 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 launch process and helping the fire extinguishing bomb 6 to be smoothly loaded into the chamber.

[0093] In the present disclosure, a partition is provided in the ammunition storage chamber 42 to divide the ammunition storage chamber 42 into two chambers; wherein, the size of each chamber is set to only allow the fire extinguishing bomb 6 to be placed in the same posture. By dividing it 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 placed, ensuring the working efficiency and effect of the fire projection cannon.

[0094] At the same time, based on the size design of the chamber, it prevents the mutual interference and collision of the fire extinguishing bombs 6 in the ammunition storage chamber 42, reducing the possibility of misplacement. At the same time, the orderly storage also helps the operator to identify and retrieve the fire extinguishing bombs 6 more quickly. The two independent chambers can respectively store different types of fire extinguishing bombs 6 or spare fire extinguishing bombs 6 to meet different fire extinguishing requirements.

[0095] In addition, based on the setting of the ammunition storage chamber 42, different types of fire extinguishing bombs 6 can also be respectively stored in the two chambers for quick retrieval when needed. For example, one chamber can store the fire extinguishing bombs 6 for solid combustion, while the other chamber stores the fire extinguishing bombs 6 for liquid or gas combustion.

[0096] Of course, it can also be that one chamber can store the fire extinguishing bombs 6 in use, while the other chamber serves as a spare storage. When the fire extinguishing bombs 6 in the main chamber are exhausted, it can be quickly switched to the spare chamber to ensure the continuous operation of the fire projection cannon.

[0097] The separated chambers are convenient for 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 timely replace the damaged or expired fire extinguishing bombs 6 to ensure the reliability and safety of the fire projection cannon.

[0098] In an embodiment provided by the present disclosure, the first linear driving member 44 includes: a nut seat disposed on the body 1, the nut seat being provided with a threaded hole and a through hole; a lead screw inserted into the threaded hole and rotatably connected to the body 1; a smooth rod inserted into the through hole, and both ends of the smooth rod being rotatably connected to the body 1; and a first motor disposed on the positioning plate 41, the output shaft of which is drivingly connected to the lead screw to drive the lead screw to rotate.

[0099] The threaded hole allows the lead screw to be inserted and engage with the internal thread of the nut seat. When the lead screw rotates, due to the interaction with the thread, the positioning block 46 will move along the axial direction of the lead screw. The smooth rod can improve the stability of the positioning block 46 during linear movement, preventing it from rotating or undergoing other unexpected movements.

[0100] Specifically, one end of the lead screw is rotatably connected to the positioning plate 41 through a first bearing, and the other end is connected to the nut seat. The lead screw serves as a transmission element, and its rotation will be converted into a linear motion of the positioning block 46. The first motor is disposed on the positioning plate 41, and its output shaft is drivingly connected to the lead screw. When the motor rotates, it will drive the lead screw to rotate together, thereby driving the positioning block 46 to move on the lead screw.

[0101] When it is necessary to adjust the position of the ammunition storage bin 42, the first motor is started, and its output shaft drives the lead screw to rotate. The rotation of the lead screw is converted into a linear motion of the positioning block 46 through the nut. The positioning block 46 moves on the lead screw, thereby driving the ammunition storage bin 42 connected thereto to perform a linear movement. Based on the cooperation between the lead screw and the positioning block 46, as well as the transmission relationship between the lead screw and the nut, the smoothness and accuracy of the movement process of the ammunition storage bin 42 can be ensured.

[0102] In an embodiment provided by the present disclosure, both the ammunition storage bin 42 and the first linear driving member 44 are provided in two sets, and the ammunition storage bins 42 are respectively disposed on both sides of the material discharge port; the first linear driving member 44 is correspondingly connected to the ammunition storage bin 42.

[0103] By providing an ammunition storage bin 42 on each side of the material discharge port, it can be ensured that during the shooting process of the gun barrel 2, when one ammunition storage bin 42 is feeding ammunition, the other ammunition storage bin 42 has already prepared the next fire extinguishing bomb 6, thereby greatly reducing the waiting time for ammunition feeding and improving the ammunition feeding efficiency. Since the two ammunition storage bins 42 alternate in feeding ammunition, there is almost no interruption in ammunition feeding during the shooting process, thereby enhancing the continuity of shooting.

[0104] Each ammunition storage bin 42 is equipped with an independent first linear driving member 44. Even if one first driver 83 fails, the other first driver 83 can still operate normally, thereby increasing the reliability of the equipment.

[0105] In an embodiment provided by the present disclosure, a limit switch is provided on the positioning plate 41, and the limit switch is communicatively connected to the controller and the first linear driving member 44.

[0106] The limit switch is used to detect whether the ammunition storage bin 42 reaches a preset limit position. The preset limit position may include the maximum and minimum moving distances of the ammunition storage bin 42 to ensure that the ammunition storage bin 42 moves within a safe range.

[0107] The controller is the control hub of the fire projection gun machine, responsible for receiving and processing various signals and controlling the operation of the device according to these signals. When the limit switch is triggered, it sends a signal to the controller, informing that the ammunition storage bin 42 has reached the preset limit position.

[0108] When the controller receives the signal from the limit switch, it sends an instruction to the first linear driving member 44 to stop moving, change the moving direction, or reduce the moving speed. This can prevent the ammunition storage bin 42 from exceeding its safe moving range, thus avoiding equipment damage or personal injury.

[0109] In practical applications, the setting of the limit switch can be adjusted according to specific device requirements. For example, a limit switch can be set at each of the maximum and minimum moving positions of the ammunition storage bin 42 to ensure that the ammunition storage bin 42 does not exceed these positions during movement. In addition, additional limit switches can be set at some key positions of the ammunition storage bin 42 to provide more precise position control and protection.

[0110] According to a specific implementation manner of the present disclosure, a material distribution device for a fire projection gun machine is provided, wherein, Figures 1 to 7 and Figure 10 One specific embodiment is shown.

[0111] Refer to Figures 1 to 7 and Figure 10 As shown, the material distribution device for the fire projection gun machine includes a receiving seat 51, a sealing seat 52, a gas storage pipe 54, and a pushing member 55. An arc-shaped groove 511 for defining the position of the fire extinguishing bomb 6 is provided on the receiving seat 51 to ensure that the fire extinguishing bomb 6 does not deviate from the predetermined path during transportation. The front end of the arc-shaped groove 511 is hermetically connected to the bearing seat 56, and the rear end is hermetically connected to the sealing seat 52 to ensure that air flow does not leak during transportation and guarantee the gas pressure.

[0112] 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. A control valve 58 is provided on the control pipe 57 to control the on-off of the air flow. The moving end of the pushing member 55 is connected to the gun barrel 2, and the moving direction of this moving end is parallel to the axis direction of the gun barrel 2, so that the gun barrel 2 can move along the arc-shaped groove 511 to approach or move away from the sealing seat 52. When the fire extinguishing bomb 6 is pushed to near the sealing seat 52, the pushing member 55 will push the gun barrel 2 to move along the arc-shaped groove 511, so that the gun barrel 2 approaches or moves away from the sealing seat 52, so as to accurately send the fire extinguishing bomb 6 into the gun barrel 2.

[0113] When the gun barrel 2 abuts against the sealing seat 52, the fire extinguishing bomb 6 has been successfully pushed into the gun barrel 2 at this time. Open the control valve 58, and the pneumatic device 3 supplies air flow 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 be ejected from the chamber, so as to fly and fall into the target position to participate in the fire extinguishing work. After the ejection work 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.

[0114] The design of the material distribution device makes the conveying process of the fire extinguishing bomb 6 more automated, efficient and safe. By precisely controlling the on-off of the air flow 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 projection gun machine.

[0115] In an embodiment provided by the present disclosure, the pushing member 55 includes a hoop 551 and a linear module 552. The linear module 552 is connected to the gun barrel 2 through the hoop 551 to push the gun barrel 2 to move in the arc-shaped groove 511. The hoop 551 can fix and connect the gun barrel 2 and the linear module 552. During assembly, the hoop 551 tightly wraps the outer surface of the gun barrel 2 to ensure the stability and accuracy of the gun barrel 2 during movement. In the fire projection gun machine, the linear module 552 is connected to the gun barrel 2 through the hoop 551. When the linear module 552 acts, it will push the gun barrel 2 to move in the arc-shaped groove 511 to realize the automatic loading of the fire extinguishing bomb 6.

[0116] When it is necessary to send the fire extinguishing bomb 6 from the ammunition storage bin 42 into the gun barrel 2, the control system will send an instruction to the linear module 552. After receiving the instruction, the linear module 552 will start the motor and push the gun barrel 2 to move in the arc-shaped 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 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 acting. At this time, the fire extinguishing bomb 6 has been successfully loaded and can perform the shooting operation.

[0117] It should be noted that the material and structure of the hoop 551 should be strong enough to withstand the forces and impacts that may be generated when the gun barrel 2 moves.

[0118] The linear module 552 generally includes parts such as a motor, a guide rail, a positioning block 46, and a control system, and can achieve precise linear motion.

[0119] In an embodiment provided by the present disclosure, a second bearing for sleeving 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 maintain the correct position during movement and preventing it from shifting or shaking.

[0120] The gun barrel 2 is inserted into the second bearing, which helps to reduce the resistance when the gun barrel 2 moves and makes 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 carry away these heats, playing a role in cooling and preventing 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.

[0121] In addition, the lubricating oil can also form a lubricating film between the gun barrel 2 and the second bearing, further reducing the friction coefficient, making the gun barrel 2 move more smoothly in the bearing seat 56. Therefore, the conveying efficiency of the entire material distribution device will be improved, which helps to speed up the loading speed of the fire extinguishing bomb 6 and improve the response speed of the fire projection gun machine.

[0122] In an 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 gun barrel 2 or other connecting components.

[0123] Specifically, the sealing ring is made of an elastic material, such as rubber, silica gel, or plastic. 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 configure them flexibly according to actual needs.

[0124] It should be noted that when installing the sealing ring, it is completely embedded in the sealing seat 52 and can be closely attached to the end face of the gun barrel 2, thereby ensuring airtightness.

[0125] In the present disclosure, the inner diameter of the air outlet on the sealing seat 52 is smaller than the inner diameter of the gun barrel 2, so that a pressure difference can be formed between the sealing seat 52 and the gun barrel 2, thereby ensuring that the gas can flow out of the gun barrel 2 more smoothly, rather than experiencing backflow or leakage. Due to the smaller inner diameter of the air outlet, there will be a certain pressure loss when the fluid passes through, but this loss helps to ensure the flow stability and directionality of the fluid in the pipeline, enabling the high-pressure gas to push the fire extinguishing bomb 6 to move smoothly along the target position.

[0126] The smaller inner diameter of the air outlet than that of the gun barrel 2 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 size of the air outlet according to specific usage requirements and environmental conditions.

[0127] In an embodiment provided in the present disclosure, the gas storage pipe 54 is in a C shape. The C-shaped gas storage pipe 54 can make more effective 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 a fire extinguishing system, 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 due to external factors during use.

[0128] In an embodiment provided in the present disclosure, the material distribution device further includes an arc-shaped plate 59, and the arc-shaped plate 59 is connected to the gas storage pipe 54 and is inclined upward toward the upper side of the control valve 58. The arc-shaped plate 59 can play a certain role in covering and protecting the control valve 58, and at the same time, such a setting also has a certain aesthetic property.

[0129] In the present disclosure, a lifting device 8 for a fire projection cannon machine is provided. Figures 4 to 7 One specific implementation manner is shown.

[0130] Refer to Figures 4 to 7 As shown, the lifting device 8 for the fire projection cannon machine includes: a sector gear 81, the axis of which is rotatably connected to the machine body 1, and the part away from the axis is connected to the gun mount 111. When the sector gear 81 rotates, the gun mount 111 will also move accordingly, so as to realize the angle and height adjustment of the gun barrel 2.

[0131] The driving wheel 82 is formed into a tooth profile adapted to 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 conditions of large load or high speed. The first driver 83 is fixedly arranged on the machine body 1, and the driving wheel 82 is coaxially arranged on the output shaft of the first driver 83, and the driving wheel 82 meshes with the sector gear 81.

[0132] Through the above technical solution, when it is necessary to adjust the angle and height of the gun carriage 111, the first driver 83 is started to drive the driving wheel 82 to rotate, and the rotation of the driving wheel 82 will drive 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, so as to realize the accurate aiming and projection of the gun barrel 2. And the lifting device 8 has the advantages of compact structure, high transmission efficiency, large adjustment range and high precision.

[0133] In an embodiment provided by the present disclosure, two sets of sector gears 81 are arranged at intervals, and two sets of driving wheels 82 are arranged to mesh with the sector gears 81 one by one. Through the cooperation of the two sets of sector gears 81 and driving wheels 82, the output torque can be significantly increased. When one set of gears is running, the other set can be used as a backup or auxiliary to reduce the risk of system failure caused by the failure of a single component. In this way, higher precision and stability can be ensured when the gun barrel 2 adjusts the angle and height. Especially in dealing with large-scale fires or emergency situations that require rapid response, it can ensure that the fire projection gun machine can quickly and accurately locate the fire source and effectively carry out fire extinguishing operations.

[0134] In an embodiment provided by the present disclosure, both sector gears 81 are 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 bearings 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 maintain stability during rotation and is not prone to deviation or shaking.

[0135] The third bearing 87 can bear large radial and axial loads, ensuring the stability of the connecting rod shaft 84 during high-speed rotation or under large torque, and further enhancing the connection reliability between the connecting rod shaft 84 and the machine body 1.

[0136] 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 machine body 1 through bearings, the sector gear 81 can maintain stability during rotation. At the same time, because the axis line of the sector gear 81 is horizontally arranged, the rotation of the sector gear 81 will drive the gun carriage 111 to perform pitching motion, thereby adjusting the angle and height of the gun barrel 2.

[0137] When selecting the third bearing 87, it is necessary to comprehensively consider factors such as the diameter, rotational speed, and load-bearing capacity of the connecting rod shaft 84. Ensure that the selected bearing can withstand various forces and torques generated by the connecting rod shaft 84 during operation. In this regard, those skilled in the art can flexibly configure according to actual needs.

[0138] In an embodiment provided by the present disclosure, the jacking device 8 further includes a reinforcing rod 85. The reinforcing rod 85 is arranged between the two sector gears 81, and both ends of the reinforcing rod 85 are fixedly connected to the two sector gears 81 respectively.

[0139] Based on the setting of the reinforcing rod 85, by connecting its two ends to the two sector gears 81, a stable triangular structure can be formed, which can effectively resist external loads and torques, thereby increasing the structural strength of the entire jacking device 8. At the same time, it can also keep the two sector gears 81 synchronized during rotation, ensuring the smooth movement of the gun carriage 111. In the case of large loads or long-term operation, the sector gear 81 may be subjected to large stresses and deformations. The presence of the reinforcing rod 85 can share these stresses and deformations, thereby protecting the sector gear 81 from damage.

[0140] In the present disclosure, a weight-reducing groove 86 is provided on the sector gear 81. The design of the weight-reducing groove 86 can not only reduce the overall mass of the gear, but also reduce the moment of inertia of the gear, reduce the driving force required during high-speed rotation or under large loads, thereby improving the transmission efficiency to a certain extent. In addition, the weight-reducing groove 86 can optimize the stress distribution of the gear, reduce the influence of stress concentration, and thus improve the fatigue strength and durability of the gear.

[0141] Furthermore, the groove 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 more while meeting the structural strength requirements of the gear. Since the weight-reducing groove 86 can reduce the moment of inertia of the gear, it can reduce the useless power consumption during the rotation of the gear. The design with a gradually increasing groove width can make the weight-reducing groove 86 generate less air resistance during the rotation of the gear, further reducing power consumption and improving the transmission efficiency.

[0142] In addition, this design can also increase the surface area of the gear, thereby increasing the contact area with the surrounding air, which is beneficial to the faster dissipation of the heat generated when the gear rotates at high speed, reducing the temperature of the gear and improving its service life.

[0143] 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. Due to the larger axial tooth thickness of the driving wheel 82, when it meshes with the sector gear 81, it can provide a larger contact area and more stable transmission. This can reduce vibrations and noises caused by poor meshing, and improve the smoothness and reliability of gear transmission.

[0144] Since the driving wheel 82 has a larger axial tooth thickness, it can withstand greater loads and torques, which can, to a certain extent, improve the transmission efficiency and reduce the energy loss caused by poor meshing.

[0145] In an embodiment provided by the present disclosure, the first driver 83 includes a motor and a speed reducer. The output shaft of the motor is connected to the speed reducer, and the output shaft of the speed reducer is connected to the driving wheel 82, which can convert the high-speed low-torque output of the motor into a low-speed high-torque output, helping to provide sufficient torque to drive the sector gear 81 and the gun carriage 111 to perform lifting movements. At the same time, the speed reducer can also reduce the impact and vibration generated by the direct drive of the motor to the driving wheel 82.

[0146] When the motor starts, its output shaft drives the speed reducer to rotate. The speed reducer converts the high-speed low-torque output of the motor into a low-speed 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 realizing the adjustment of the position of the gun carriage 111.

[0147] In a specific embodiment according to the present disclosure, a lifting device 9 for a fire projection gun machine is provided. Figures 1 to 3 and Figure 7 and Figure 8 One specific embodiment is shown.

[0148] Refer to Figures 1 to 3 and Figure 7 and Figure 8As shown in the figure, the lifting device 9 for a fire 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. In this way, the cannon can be supported at multiple points, and it can maintain stability even on uneven roads through height adjustment. The support mechanism 91 includes a positioning end and a linear telescopic end. The positioning end is fixedly connected to the load-carrying plate 7, and a footrest 93 is provided at the bottom of the linear telescopic end. The lifting device 9 further includes a cross beam 92, and both ends of the cross beam 92 are respectively connected to the positioning ends of different support mechanisms 91, thus forming a stable frame structure. This can not only enhance the stability of the entire lifting device 9 but also prevent relative displacement of the support mechanisms 91 during the lifting process.

[0149] Through the above technical solution, by connecting multiple independently adjustable support mechanisms 91 and the cross beam 92, the lifting device 9 can provide stable support on various terrains. 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 situation of the terrain to achieve the best support effect, thereby adapting to different terrains and aiming requirements. It has good flexibility and applicability, and can enable the fire projection cannon to work stably on different roads.

[0150] In an embodiment provided by the present disclosure, a ball socket is provided on the footrest 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 footrest 93 is the part of the lifting device 9 in contact with the ground and is responsible for supporting the entire device. The ball socket provided on the footrest 93 is usually a groove in the shape of 2 / 3 of a sphere, and the spherical volume of the groove is at least greater than 3 / 5 of the whole sphere. In this way, the ball head 95 can rotate and tilt to a certain extent.

[0151] Since the ball head 95 can freely rotate and tilt in the ball socket, the torque and torsion generated due to the 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 achieving a stable support effect, enabling the lifting device 9 to adapt to different terrains and conditions, and ensuring that the fire projection cannon can always maintain stability.

[0152] When the lifting device 9 is placed on an uneven terrain, due to the changes in the ground height and angle, the pressures and angles borne by each support mechanism 91 will also be different. At this time, the cooperative 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.

[0153] Specifically, the ball head 95 can rotate and tilt in the ball socket, ensuring that the linear telescopic end always remains perpendicular or nearly perpendicular to the ground, providing stable support for the lifting device 9, which is particularly suitable for fire projection cannons operating in complex terrains and conditions. Whether on rugged mountain roads, muddy wetlands, or uneven urban ground, this lifting device 9 can provide stable support for the cannon, ensuring that it can accurately and efficiently perform fire extinguishing tasks.

[0154] In the embodiment provided by the present disclosure, the support mechanism 91 is configured as a hydraulic cylinder, and a foot pad is provided at the end of the hydraulic cylinder; multiple hydraulic cylinders are respectively connected to a hydraulic station through oil pipes; the hydraulic station is communicatively connected to a controller.

[0155] The hydraulic cylinder uses the pressure of hydraulic oil to generate thrust or pull, thereby controlling its own lifting. A foot pad is provided 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, and the hydraulic station is responsible for providing and controlling the pressure and flow rate of the hydraulic oil. By adjusting the pressure and flow rate of the hydraulic station, the lifting speed and position of each hydraulic cylinder can be precisely controlled, thereby achieving precise positioning of the cannon.

[0156] The controller can adjust the parameters of the hydraulic station in real time according to a preset program or the operator's instructions, thereby controlling the lifting 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.

[0157] Among them, the foot pad is usually made of wear-resistant and anti-slip materials to ensure reliable support under various terrains and conditions.

[0158] In the present disclosure, the footrest 93 is configured as a rust-resistant metal seat. Metal materials usually have high strength and can withstand large pressures and weights, ensuring that the lifting device 9 remains stable under various working conditions. At the same time, the metal seat also has good thermal conductivity, which can quickly transfer heat to the surrounding environment, reducing the risk of performance degradation or damage caused by high temperatures. In this way, the fire projection cannon can effectively adapt to various working environments, such as humid, rainy, or even coastal environments with strong corrosion.

[0159] Furthermore, the support mechanism 91 is configured as four groups arranged symmetrically; the positioning ends of each support mechanism 91 are fixedly connected to the corners of the load-carrying plate 7. In this way, the lifting device 9 can evenly distribute the load when bearing weight, avoiding excessive pressure on a certain part and causing damage or instability. In emergency situations such as fire rescue, the lifting device 9 can quickly and accurately adjust the position and angle of the cannon to ensure the smooth progress of the rescue work.

[0160] In the present disclosure, a cushion plate 94 is provided between the support mechanism 91 and the load plate 7. The cushion plate 94 can provide a layer of cushioning between the support mechanism 91 and the load plate 7, reducing the direct stress generated during mechanical vibration, impact or adjustment processes. This can effectively protect the load plate 7 and the fire projection cannon machine installed thereon from being damaged or excessively worn. Additionally, the cushion plate 94 can also increase the contact area between the support mechanism 91 and the load plate 7, improving stability. Especially on uneven or inclined ground, the cushion plate 94 can ensure stable contact between the support mechanism 91 and the load plate 7, preventing sliding or tilting.

[0161] Specifically, the cushion plate 94 can be detachably arranged between the support mechanism 91 and the load plate 7, so that it can be adjusted or replaced as needed to adapt to different working environments and requirements. For example, when it is necessary to adjust the height or angle of the fire projection cannon machine, it can be achieved by increasing or decreasing the number or thickness of the cushion plates 94.

[0162] Among them, the cushion plate 94 can be configured as a rubber cushion plate 94, a metal cushion plate 94 or a composite material cushion plate 94. Among them, the rubber cushion plate 94 has good cushioning performance and anti-slip performance, and is suitable for occasions where vibration and impact need to be reduced. The metal cushion plate 94 has high strength and wear resistance, and is suitable for occasions where large pressure and friction need to be borne. The composite material cushion plate 94 also has good cushioning performance, anti-slip performance and wear resistance. For the type of the cushion plate 94, those skilled in the art can flexibly select according to the application environment.

[0163] According to a specific embodiment of the present disclosure, a position adjustment device for a fire projection cannon machine is provided, wherein, Figures 4 to 6 One specific embodiment is shown.

[0164] Referring to Figures 4 to 6 As shown, the position adjustment device for the fire projection cannon machine includes: a worm gear, 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 line of the worm gear; the other end of the worm gear is rotatably connected to the load plate 7. A worm, rotatably arranged on the load plate 7 and meshed with the worm gear; and a second motor 101, the output shaft of which is drivingly connected to the worm; when the second motor 101 drives the worm to rotate, the worm gear drives the machine body 1 to rotate with the axis line of the worm gear as the rotation center.

[0165] With the above technical solution, when the second motor 101 is activated and drives the worm to rotate, due to the meshing relationship between the worm and the worm wheel, the worm wheel will also start to rotate. 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 line of the worm wheel as the rotation center. In this way, the position of devices such as the gun barrel 2 located on the body 1 can be adjusted. The worm and worm wheel mechanism has the characteristics of high transmission accuracy and large transmission ratio, making the rotation of the body 1 more accurate and reliable.

[0166] The positioning device takes the vertical direction as the rotation center, enabling the body 1 to also rotate around the rotation center of the positioning device, so that the fire projection cannon can cover a wider area. In this way, no matter in which direction the fire source is located, the cannon can quickly and accurately adjust the shooting angle, thereby improving its ability to respond to different fire source positions. When the position of the fire source changes, the fire projection cannon can also quickly adjust the shooting angle through the positioning device, shortening the response time and improving the fire extinguishing efficiency.

[0167] In an embodiment provided by the present disclosure, the positioning device includes a housing 102, and the housing 102 is fixedly connected to the load plate 7; an opening corresponding to the worm is provided on the housing 102, and the worm wheel is disposed in the housing 102 and meshes with the worm at this opening.

[0168] The housing 102 is fixedly connected to the load plate 7, providing a closed environment for the worm wheel, protecting the worm wheel from dust, moisture and other potential contaminants, thereby extending its service life. An opening corresponding to the worm is provided on the housing 102, which allows the worm to extend into the interior of the housing 102 from the outside and mesh with the worm wheel, ensuring both the transmission relationship between the worm wheel and the worm and making the whole device more neat and unified in appearance. Thus, when the worm wheel is driven by the worm, it can rotate smoothly, thereby driving the fire projection cannon provided on the body 1 to rotate.

[0169] In addition, the protective effect of the housing 102 can also reduce the impact or damage on the worm wheel from the outside, thus playing a certain protective role for the worm and worm wheel.

[0170] 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 wheel, and the outer periphery of the fourth bearing 103 is sleeved in the housing 102. The inner side of the fourth bearing 103 being fixedly connected to the worm wheel can ensure that the worm wheel rotates more smoothly and without jitter, thereby achieving precise control and stable operation of the fire projection cannon.

[0171] The outer circumference of the fourth bearing 103 is sleeved in the housing 102, which can form a rotating support structure to avoid direct contact between the worm gear and the housing 102, thereby reducing friction and wear. This can not only improve the service life of the positioning device but also reduce the noise and heat generated by friction.

[0172] To reduce friction and wear, an appropriate amount of lubricant can be added between the fourth bearing 103, the worm gear, and the housing 102, thereby improving the operating efficiency of the positioning device and extending its service life.

[0173] In an embodiment provided by the present disclosure, the positioning device includes an angle sensor for detecting the rotation angle information of the worm gear. The angle sensor is communicatively connected to a controller, and the controller correspondingly controls the movement turntable of the second motor 101 according to the rotation angle information of the worm gear.

[0174] 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 through which the worm gear has rotated in real time and convert this information into an electrical signal. The controller receives the electrical signal from the angle sensor and controls the movement state of the second motor 101 based on these signals.

[0175] Specifically, when the worm gear rotates driven by the worm, the angle sensor will detect the rotation angle information of the worm gear in real time and convert 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 will generate corresponding control instructions based on the current rotation angle information of the worm gear and the preset target rotation angle information (if necessary), and send the generated control instructions to the second motor 101 to control the movement state of the motor. If the worm gear has rotated through a predetermined angle, the controller may send an instruction to stop the motor; if the worm gear has not reached the predetermined angle, the controller will continue to send an instruction to keep the motor rotating. Through the real-time monitoring of the angle sensor and the precise control of the controller, the positioning device can achieve precise rotation angle control of the worm gear, thereby improving the positioning accuracy and shooting accuracy of the fire projection cannon.

[0176] Furthermore, the body 1 is connected to the worm gear through a mounting plate 105; a sliding mechanism is provided between the mounting plate 105 and the body 1; wherein, the sliding mechanism includes guide rails 104, guide blocks, and a second driver. The guide rails 104 are configured to be at least two groups and are arranged in parallel on the mounting plate 105. The guide blocks are slidably connected to the guide rails 104; one end of the second driver is connected to the mounting plate 105, and the other end is connected to the guide blocks. The top of the guide blocks is fixedly connected to the body 1; the second driver is used to push the guide blocks to move along the guide rails 104.

[0177] The mounting plate 105 is used to connect the body 1 and the worm gear, so that the position of the body 1 can be changed as the mounting plate 105 moves.

[0178] The guide rail 104 can ensure that the body 1 moves in a straight line or a predetermined path when moving. By slidably connecting the guide block to the guide rail 104, 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 body 1, when the guide block moves, the body 1 will move accordingly.

[0179] Therefore, when the second driver is started, it will push the guide block to move along the guide rail 104. Since the guide block is fixedly connected to the body 1, the body 1 will also move as the guide block moves. 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 projection cannon to the environment.

[0180] According to a specific embodiment of the present disclosure, a barrel 2 for a fire projection cannon is provided, wherein, Figures 14 to 16 One specific embodiment is shown.

[0181] Refer to Figures 14 to 16 As shown, the barrel 2 for the fire projection cannon includes a tube body 21 and a spoiler 22. The spoiler 22 is sleeved on one end of the tube body 21 and fixedly connected to the tube body 21. Among them, the spoiler 22 is conical, and its diameter gradually increases in the direction away from the tube body 21. And the spoiler 22 is provided with spoiler holes 23. The spoiler holes 23 extend along the gas flow direction and penetrate through the spoiler 22. One end of the spoiler hole 23 is located on the outer wall of the spoiler 22, and the other end is located on the inner wall of the spoiler 22.

[0182] Through the above technical solution, 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 holes 23, when the fire extinguishing bomb 6 leaves the barrel 2, the gas can quickly flow out through the spoiler holes 23, thereby reducing the pressure in the barrel 2, which helps 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 will generate high pressure due to sudden release. The spoiler holes 23 allow the gas to flow out quickly, thereby reducing the pressure in the barrel 2 and reducing the resistance to the fire extinguishing bomb 6. Due to the existence of the spoiler holes 23, certain disturbances will be generated when the gas flows out, and these disturbances help to improve the flight stability of the fire extinguishing bomb 6 and make it easier to reach the predetermined target. In addition, the design of the spoiler holes 23 also helps to reduce the noise generated when the barrel 2 is fired.

[0183] In the present disclosure, a plurality of spoiler holes 23 are arranged and evenly spaced along 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.

[0184] The arrangement of the plurality of spoiler holes 23 can generate more disturbances, which helps to improve the flight trajectory and stability of the fire extinguishing bomb 6.

[0185] It should be noted that the number and layout of the spoiler holes 23 can be adjusted according to needs to adapt to different projection requirements and working environments.

[0186] In the present disclosure, six spoiler holes 23 are arranged, which can maximize the air flow disturbance effect on the basis of ensuring the overall strength of the spoiler cover 22.

[0187] In the present disclosure, the angle between the generatrix and the axis of the cone of the spoiler cover 22 is 25° to 35°. Such a design enables the gas to generate appropriate disturbances when flowing through the spoiler cover 22, thereby reducing air resistance and improving the flight stability and range of the fire extinguishing bomb 6.

[0188] Specifically, in the exemplary embodiment of the present disclosure, the angle between the generatrix and the axis of the cone of the spoiler cover 22 is 30°, which can achieve a better spoiler effect. In other embodiments, the angle between the generatrix and the axis of the cone of the spoiler cover 22 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 the environmental conditions to determine the optimal angle range to obtain the best spoiler effect and projection performance.

[0189] In the present disclosure, a step is provided on the inner wall of the spoiler cover 22, and a groove adapted to the step is provided on the tube body 21. The cooperation between the step on the inner wall of the spoiler cover 22 and the groove on the tube body 21 can play a positioning and guiding role to help the spoiler cover 22 and the tube body 21 for quick assembly.

[0190] In the present disclosure, a threaded hole is provided on the spoiler cover 22, and a screw is screwed into the threaded hole to press against the tube body 21. When the screw is screwed into the threaded hole, a downward force will be generated, and this force will be evenly distributed on the tube body 21, thereby ensuring a tight connection between the spoiler cover 22 and the tube body 21 and effectively preventing loosening or falling off caused by vibration or other external forces.

[0191] During maintenance, only tools such as a screwdriver are needed to easily screw in or out the screw, thereby realizing the installation or disassembly of the spoiler cover 22.

[0192] In the present disclosure, the threaded holes are provided in at least three groups and are evenly spaced along the circumferential direction of the spoiler 22. By evenly distributing the threaded holes along the circumferential direction of the spoiler 22, it is ensured that the spoiler 22 obtains uniform support and fixation at multiple points, which increases the structural stability of the spoiler 22 and makes it less likely to deform or be damaged when subjected to external forces.

[0193] In the present disclosure, the material of the pipe body 21 is chrome molybdenum steel. In this way, even in an environment of high pressure, high temperature or high stress, the pipe body 21 made of chrome molybdenum steel can maintain its structural integrity and stability and is not prone to deformation or rupture.

[0194] In addition, the chromium element in chrome molybdenum steel can form a dense oxide film, which can effectively prevent the pipe body 21 from being oxidized and corroded, so that the chrome molybdenum steel pipe body 21 can also maintain a long service life in a harsh environment (such as high humidity, high salinity, etc.).

[0195] 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 component, reducing weight can reduce energy consumption, improve response speed, and reduce the burden on the entire system.

[0196] In addition, a dense oxide film is easily formed on the surface of the aluminum alloy, which can resist the erosion of various chemical substances, including water, air, and certain acids and alkalis, etc., so that the spoiler can also maintain a long service life in a harsh environment and reduce the frequency of maintenance and replacement.

[0197] According to a specific embodiment of the present disclosure, a fire extinguishing bomb 6 for a fire projection gun machine is provided, wherein, Figure 17 One specific embodiment is shown.

[0198] Refer to Figure 17 As shown, the fire extinguishing bomb 6 for the fire projection gun machine includes a warhead 61, a middle water tank 62, a medicine tank 63, a chip tank 64, and a tail plate 65 that are all coaxially arranged. Among them, both 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; among them, an overflow hole is provided at the tip of the warhead 61, and a head plug 67 is hermetically inserted into the overflow hole.

[0199] The intermediate water storage tank 62 is located between the warhead 61 and the chip storage tank 64 and is usually used to store water or other fire extinguishing liquids. When the fire extinguishing bomb 6 is launched and hits the target, the liquid in the intermediate water storage tank 62 will flow out through the overflow hole of the warhead 61 to initially cool and extinguish the fire source.

[0200] The chemical agent storage tank 63 is connected to the chip storage tank 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 act together with or independently of the liquid in the intermediate water storage tank 62 to achieve a better fire extinguishing effect.

[0201] The chip storage tank 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 communicatively connected to the tail plate 65, enabling the status information of the fire extinguishing bomb 6 to be remotely monitored or controlled.

[0202] The tail plate 65 is located at the tail of the fire extinguishing bomb 6 and is connected to the chip storage tank 64. The tail plate 65 not only plays a connecting and fixing role but also conducts data transmission with the chip 66 through the communication connection. This enables the status information of the fire extinguishing bomb 6 to be remotely read or controlled, improving the efficiency and safety of the fire extinguishing operation.

[0203] Among them, the tip of the warhead 61 is provided with an overflow hole, and a head plug 67 is hermetically inserted in the overflow hole. The design of the overflow hole can be used for filling liquids. During the filling operation, the liquid is poured from the overflow hole of the warhead 61. As the filling work continues, based on the oscillation of the liquid, bubbles or foam are generated on the liquid surface. Therefore, after the filling is completed, filling will continue until the bubbles or foam in the liquid overflow, and finally, the head plug 67 is used for pressing. This can further reduce the internal voids, effectively eliminate the bubbles, fill the warhead 61 with liquid, which is beneficial for the fire extinguishing bomb 6 to fly smoothly along the launch trajectory and avoid disturbing the flight trajectory due to the liquid sloshing inside. In addition, since the head plug 67 is sharp, it has a certain wind-breaking effect and can help the fire extinguishing bomb 6 fly smoothly.

[0204] When the fire extinguishing bomb 6 is launched and hits the target, the liquid in the intermediate water storage tank 62 will flow out through the overflow hole of the warhead 61. At the same time, the chemical agent will be released, so as to act together with or independently of the liquid in the intermediate water storage tank 62 to achieve a better fire extinguishing effect.

[0205] Through the above technical solution, when the fire extinguishing bomb 6 is launched and hits the target, the overflow holes of the warhead 61 will open, and the liquid in the middle water tank 62 will flow out rapidly. At the same time, the medicament will be released, so as to act together with or separately from 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.

[0206] In the present disclosure, a strip-shaped groove 68 for installing a swirl plate is provided on the inner wall surface of the middle water tank 62. The strip-shaped grooves 68 all extend along the axial direction of the middle water tank 62. The swirl plate is embedded in the strip-shaped groove 68, and the width of the swirl plate is smaller than the radius of the middle water tank 62. With such a setting, the swirl plate can change the direction and speed of the liquid, so as to form a swirling flow in the middle water tank 62, which helps to enhance the kinetic energy of the liquid, promote the mixing of the fire extinguishing medicament and water, and thus improve the fire extinguishing efficiency.

[0207] The strip-shaped grooves 68 extend along the axial direction of the middle water tank 62, so that the swirl plates can be evenly distributed along the length direction of the middle water tank 62, which can ensure that the liquid can form an effective swirl throughout the middle water tank 62. At the same time, it can also prevent the liquid from being too concentrated or too sparse in some areas.

[0208] The swirl plate is embedded in the strip-shaped groove 68, so that the swirl plate can be firmly fixed on the inner wall surface of the middle water tank 62. In this way, 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, thus ensuring the smooth flow of the liquid.

[0209] By arranging a swirl plate in the middle water tank 62, the liquid can generate a swirl when flowing through the swirl plate. The swirling flow can not only increase the kinetic energy of the liquid, but also make the liquid mix better with the fire extinguishing medicament in the medicament tank 63, thus improving the fire extinguishing effect.

[0210] In the present disclosure, the strip-shaped grooves 68 are provided with 2n pieces, and the strip-shaped grooves 68 are symmetrically arranged in the middle water tank 62; where n is a natural number greater than or equal to 1.

[0211] Symmetrically arranging the strip-shaped grooves 68 in the middle water tank 62 makes the swirl plates also symmetrically distributed, which helps to generate a more uniform and stable swirling flow, ensuring that the kinetic energy of the liquid is fully utilized throughout the middle water tank 62. As the number of swirl plates increases (by increasing the number of strip-shaped grooves 68), the water will generate a stronger swirling effect when passing through these swirl plates, which helps to enhance the kinetic energy of the liquid, promote the more uniform mixing of the fire extinguishing medicament and water, and thus improve the fire extinguishing efficiency.

[0212] By selecting different values of n (where n is a natural number greater than or equal to 1), the number and distribution of the swirl plates can be flexibly adjusted. This can be optimized according to specific application scenarios and requirements to obtain the best fire extinguishing effect.

[0213] The symmetric strip-shaped grooves 68 and the swirl plate distribution contribute to maintaining the structural stability of the intermediate water storage tank 62. Under the action of high-speed liquid and fire extinguishing agent, the intermediate water storage tank 62 needs to have a certain compressive capacity. The symmetric design can ensure that the intermediate water storage tank 62 can evenly distribute the force when stressed, reducing the risk of stress concentration and damage.

[0214] In an embodiment provided by the present disclosure, the head insert 67 is formed into a pointed shape adapted to the tip profile of the warhead 61, so as to be able to have a wind-breaking effect. The pointed shape of the head insert 67 perfectly matches the tip profile of the warhead 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 tight fit between the two, the air resistance can be further reduced, improving the projection distance and accuracy of the fire extinguishing bomb 6.

[0215] The pointed shape of the head insert 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 be affected by air resistance. The pointed head insert 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.

[0216] Before the fire extinguishing bomb 6 is projected, the head insert 67 must firmly seal the overflow hole to prevent water leakage during flight. Once the fire extinguishing bomb 6 reaches the target position or needs to release water, the head insert 67 must be able to open quickly and reliably to ensure that the water can flow out smoothly.

[0217] In the present disclosure, the head insert 67 includes a plug-in section and a cover-pressing 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-pressing section fits against the end face of the warhead 61. The plug-in section is tightly and stably press-fitted into the overflow hole, which can effectively prevent water or fire extinguishing agent from leaking from the overflow hole during projection, ensuring the effectiveness of the fire extinguishing bomb 6. The cover-pressing section fits against the end face of the warhead 61, which not only enhances the connection stability between the head insert 67 and the warhead 61, but also plays a role in sealing and protection.

[0218] Since the plug-in section of the head insert 67 is adapted to the overflow hole, its installation process is usually relatively simple. At the same time, due to the tight fit between the cover-pressing section and the end face of the warhead 61, certain skills and tools are also required to disassemble the head insert 67, which not only ensures the easy installation of the head insert 67, but also prevents potential safety hazards caused by non-professionals disassembling it at will.

[0219] In the present disclosure, sealant is provided on the contact surfaces of the head plug 67 and the warhead 61, thereby filling and sealing the joints. It relies on temperature changes, solvent evaporation, chemical cross-linking, etc. to stably bond with the base material and gradually solidify into a plastic solid state and a viscoelastic elastic sealing material. Therefore, after applying sealant to the contact surfaces of the head plug 67 and the warhead 61, a stable sealed connection can be ensured between the two, preventing leakage of liquid or gas.

[0220] In the present disclosure, the chip bin 64 is provided with a connection hole for installing the medicine bin 63 and a chip 66 slot for installing the chip 66; the end of the medicine bin 63 is screwed to the connection hole to ensure a firm connection between the medicine bin 63 and the chip bin 64; the chip 66 is embedded in the chip 66 slot and is connected to the chip bin 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, preventing loosening or falling off caused by vibration or impact. The chip 66 slot is used to place the chip 66 and allows electrical connection between the chip 66 and the chip bin 64.

[0221] In the present disclosure, the tail plate 65 includes a base plate 651 made of plastic material and a plurality of copper rings 652 with different diameters. The base plate 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 base plate 651 melts to cover the copper rings 652; the chip 66 is communicatively connected to different copper rings 652.

[0222] The copper rings 652 are designed with different diameters, which can represent different electrical channels or signal lines, thereby realizing different communication or control functions and thus adapting to different electrical connection requirements. The copper rings 652 are embedded in the ring grooves on the base plate 651, which can ensure the stability and position accuracy of the copper rings 652. After the copper rings 652 are embedded in the ring grooves, a part of the base plate 651 will be melted to completely cover the copper rings 652, ensuring a tight connection between the copper rings 652 and the base plate 651 and providing additional protection and stability.

[0223] By changing the number, diameter and layout of the copper rings 652, as well as the connection method of the chip 66, the tail plate 65 that meets specific requirements can be customized.
