Description

Technical Field

[0001] This invention relates to the field of fire extinguishing bomb technology, and in particular to a throwing assembly and a modular fire extinguishing bomb throwing device and method for charging piles. Background Technology

[0002] With the development of society and the economy and the acceleration of urbanization, there are more and more buildings and denser buildings in cities, as well as more and more charging stations. Once a fire breaks out, if it is not extinguished in time, it will cause great loss of life and property. At present, fire rescue mainly relies on fire trucks and firefighters to directly enter the scene to extinguish the fire, but it still takes time for the firefighters to arrive, and the fire cannot be controlled in time.

[0003] The prior art patent with application number CN202421034380.6 discloses a drone fire extinguishing grenade throwing device, including a drone mounting frame and a mounting plate. The drone mounting frame is located at the center of the bottom of the drone. A spring is fixedly connected to the top of the mounting plate, and a shock-absorbing plate is fixedly connected to the top of the spring. Bolts pass through the mounting plate and the drone mounting frame. A booster is fixedly installed at the center of the bottom of the mounting plate, and a nozzle is fixedly installed at the bottom of the booster. This device can enable the fire extinguishing grenade to obtain a faster initial velocity when falling downwards, reduce the influence of wind on the falling fire extinguishing grenade, improve the accuracy of the fire extinguishing grenade throwing, and thus improve the fire extinguishing effect. However, in actual use, the fire extinguishing grenade to be thrown is positioned by the spare fire extinguishing grenade and the plunger, making the fire extinguishing grenade susceptible to resistance when thrown. It is also blocked by the limit rod during the fall, which reduces the speed of the fire extinguishing grenade. When the throwing pipe is laid horizontally or at an angle, the fire extinguishing grenade is not enough to reach the designated position, affecting its fire extinguishing effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a throwing component and a modular fire extinguishing grenade throwing device and method for charging piles.

[0005] A throwing assembly includes a throwing tube with a ejection port, and further includes: A storage shell, which is fixed to the upper side of the throwing tube and connected to the throwing tube, is used to store the fire extinguishing bomb body; The ejection assembly is located at the end of the throwing tube away from the ejection port and is used to eject the fire extinguishing bomb body inside the throwing tube for fire extinguishing operations. And an auxiliary acceleration component, which is connected to the throwing tube and is used to help increase the speed of the fire extinguishing projectile body within the throwing tube; The throwing tube is also equipped with a lifting assembly for lifting the fire extinguishing bomb body inside the storage shell, and the lifting assembly is connected to the auxiliary acceleration assembly.

[0006] Preferably, the ejection assembly includes a groove formed on the throwing tube, a first force-bearing rod slidably connected in the groove, a first elastic telescopic rod disposed between the first force-bearing rod and the inner wall of the groove, a straight rod fixed to the end of the first force-bearing rod, and a push plate connected to the end of the straight rod away from the first force-bearing rod, wherein the push plate moves against the fire extinguishing projectile body in the throwing tube.

[0007] Preferably, a support plate is fixedly provided on the outside of the storage shell, a first motor is fixedly provided on the support plate, the output shaft of the first motor is connected to a rotating rod that rotates on the support plate, and a deflector plate that moves against the first force rod is fixedly provided on the rotating rod.

[0008] Preferably, the auxiliary acceleration component includes a support plate evenly arranged in a circle on the throwing tube, a rotating rod rotatably connected to the support plate, a friction wheel fixedly arranged on the rotating rod, and a movable bevel gear fixedly arranged on the rotating rod. The movable bevel gears on two adjacent rotating rods mesh with each other, and each support plate includes two support plates fixedly connected to the throwing tube.

[0009] Preferably, the auxiliary acceleration assembly further includes a second elastic telescopic rod fixed on the storage shell, a rack plate connected to the end of the second elastic telescopic rod away from the storage shell via a connecting plate, and a second force-bearing rod fixedly connected to the other end of the rack plate. The actuating plate moves against the second force-bearing rod, and one of the rotating rods of the auxiliary acceleration assembly is provided with a movable gear that meshes with the rack plate.

[0010] Preferably, the inner wall of the throwing tube is fixed with a flared opening at the front end of the auxiliary acceleration component, and the flared opening is provided with evenly distributed balls.

[0011] Preferably, the lifting assembly includes a lifting plate slidably connected between the throwing tube and the storage shell, and a third elastic telescopic rod disposed between the lifting plate and the storage shell. The second force-bearing rod is provided with an abutment plate that moves against one end of the lifting plate. One end of the lifting plate is provided with a first inclined surface that moves against the abutment plate. The end of the lifting plate away from the first inclined surface is provided with a second inclined surface that moves against the fire extinguishing bomb body and is used to lift the fire extinguishing bomb body.

[0012] Preferably, the throwing tube is rotatably connected to a baffle at the ejection port via a rotating shaft. A torsion spring for driving the baffle to return to its original rotation is provided on the rotating shaft. A pull rope is fixedly provided on the baffle, and the end of the pull rope away from the baffle passes through a support plate and is fixedly connected to a lifting plate.

[0013] This invention discloses a modular fire extinguishing grenade throwing device for charging piles, including the aforementioned throwing assembly, a base disposed on the outside of the charging pile, a second motor fixed on the base, a rotating seat connected to the output shaft of the second motor, a fixed rod fixed on the rotating seat and movably connected to the bottom of the throwing tube via a pin, and an electric push rod fixed on the rotating seat and movably connected to the bottom of the throwing tube via a pin. The height of the electric push rod when retracted is greater than the height of the fixed rod. A monitoring and control module is also disposed on the base. The monitoring and control module includes a control module for controlling the first motor, the second motor and the electric push rod, and a camera and sensor electrically connected to the control module for monitoring the fire situation.

[0014] The present invention also discloses a method for using the aforementioned modular fire extinguishing grenade throwing device for charging piles, which further includes the following steps: S1: Fire Monitoring and Location Phase The monitoring and control module detects the fire situation in real time through cameras and sensors. After determining the location of the fire source, the control module starts the second motor and electric push rod. The output shaft of the second motor controls the rotation of the rotating base, causing the throwing tube to rotate horizontally. At the same time, the electric push rod extends and retracts, adjusting the pitch angle of the throwing tube so that the ejection nozzle is accurately aimed at the fire source. S2: Catapult preparation phase: After the angle adjustment is completed, the first motor starts, and its output shaft drives the rotating rod and the actuating plate to rotate. When the actuating plate rotates, it pushes the first force rod and the second force rod. When the first force-bearing rod moves under force, it stretches the first elastic telescopic rod to store energy. When the first force-bearing rod moves, the push plate moves synchronously. The fire extinguishing bomb body inside the throwing tube slides down to the push plate inside the inclined throwing tube. When the second force-bearing rod moves under force, it compresses the second elastic telescopic rod to store energy. When the second force-bearing rod moves, it applies a pushing force to the lifting plate through the abutment plate, causing the lifting plate to slide into the storage shell. When the lifting plate moves, it supports the fire extinguishing bomb body at the bottom of the storage shell to prevent it from falling and interfering with the contents. When the lifting plate moves, the pull rope applies tension to the baffle, causing the baffle to deflect around the pivot, and the baffle no longer blocks the ejection port; S3: Ejection Execution Phase: As the rotating rod rotates, the actuating plate no longer pushes against the first force-bearing rod, and the first elastic telescopic rod releases energy, propelling the fire extinguishing bomb body out of the throwing tube at high speed; After the fire extinguishing bomb body is ejected, the actuating plate no longer pushes against the second force rod, and the second elastic telescopic rod releases energy, causing the second force rod and rack plate to reset. When the rack plate resets, it meshes with the movable gear on the rotating rod, and the rotating rod rotates and drives the other rotating rods to rotate through the meshing between the movable bevel gears. Each rotating rod drives the friction wheel to rotate, and then drives the fire extinguishing bomb body to move inside the throwing tube through friction, gaining secondary acceleration, and finally flying out of the throwing tube at an extremely high speed. S4: Automatic Reload Phase After a fire extinguishing bomb is fired, the first and second force rods are reset. The abutment plate on the second force rod no longer pushes the lifting plate. The lifting plate is reset under the elastic force of the third elastic telescopic rod. The bottommost fire extinguishing bomb in the storage tank automatically falls into the delivery tube to replenish the material, preparing for the next launch.

[0015] As can be seen from the above technical solutions, the present invention has the following beneficial effects: 1. In this invention, a monitoring and control module is set up to monitor the fire situation at the charging pile in real time, and the action of the throwing component is controlled by the monitoring and control module. This achieves full automation from the detection of the fire to the accurate throwing, which wins valuable time for extinguishing the initial fire. It solves the problems of delayed fire extinguishing response and insufficient accuracy of fire extinguishing grenade throwing in the existing technology. It can control the fire to the smallest extent, avoid greater loss of life and property, and ensure the timeliness and effectiveness of fire extinguishing.

[0016] 2. In this invention, by controlling the operation of the first motor, the output shaft of the first motor drives the actuating plate to rotate via the rotating rod, thereby causing the actuating plate to push the first force rod and the second force rod. Part of the power is used to drive the ejection assembly to provide linear impact force, and another part of the power is used to drive the friction wheel of the auxiliary acceleration assembly to rotate, so that the fire extinguishing bomb body can obtain a higher exit speed, solving the problem of low throwing accuracy of fire extinguishing bombs in the prior art, ensuring the accurate throwing of fire extinguishing bombs, and guaranteeing the fire extinguishing effect.

[0017] 3. In this invention, when the second force-bearing rod moves, it drives the abutment plate to move synchronously. The abutment plate abuts against one end of the lifting plate, causing the lifting plate to slide into the storage shell. The second inclined surface of the lifting plate pushes the fire extinguishing bomb body at the bottom of the storage shell, preventing the fire extinguishing bomb body at the bottom of the storage shell from moving down into the throwing tube and hindering the ejection of the original fire extinguishing bomb body in the throwing tube. After the fire extinguishing bomb in the throwing tube is ejected, the first force-bearing rod, the second force-bearing rod, and the lifting plate are reset, so that the lifting plate no longer blocks the fire extinguishing bomb at the bottom of the storage shell. The fire extinguishing bomb in the storage shell automatically falls into the throwing tube under the action of gravity to replenish the material, realizing the continuous throwing of fire extinguishing bombs.

[0018] 4. In this invention, when the lifting plate slides into the storage shell, the lifting plate applies a pulling force to the baffle at the ejection port through the pull rope, causing the baffle to flip around the pivot, so that the baffle no longer blocks the ejection port and avoids the baffle from obstructing the ejection of the fire extinguishing bomb; after the fire extinguishing bomb is fired, the baffle is no longer pulled by the pull rope and will flip back to its original position under the action of the torsion spring, blocking the ejection port again, preventing external impurities from entering the throwing tube and affecting the ejection of the fire extinguishing bomb during normal storage, thus ensuring unobstructed trajectory and providing daily protection.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions: Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 9 and Figure 11 A throwing assembly includes a throwing tube 1 with a ejection port 101, and further includes a storage shell 2, an ejection assembly, and an auxiliary acceleration assembly. The storage shell 2 is fixed to the upper side of the throwing tube 1 and connected to the throwing tube 1, and is used to store the fire extinguishing bomb body 3. The ejection assembly is located at the end of the throwing tube 1 away from the ejection port 101, and is used to eject the fire extinguishing bomb body 3 in the throwing tube 1 for fire extinguishing operations. The auxiliary acceleration assembly is connected to the throwing tube 1 and is used to assist in increasing the movement speed of the fire extinguishing bomb body 3 in the throwing tube 1. The throwing tube 1 is also provided with a lifting assembly for lifting the fire extinguishing bomb body 3 in the storage shell 2, and the lifting assembly is connected to the auxiliary acceleration assembly. Specifically, the entire throwing tube 1 is arranged at an angle, so that the ejection port 101 is tilted upwards. The fire extinguishing projectile body 3 in the storage shell 2 slides down to the bottom of the throwing tube 1 under the action of gravity and comes into contact with the ejection assembly. When the fire extinguishing projectile body 3 is thrown, the ejection assembly works to push the fire extinguishing projectile body 3 in the throwing tube 1, providing initial projection velocity. When the ejection assembly is working, the auxiliary acceleration component acts, so that when the projectile body 3 moves along the inner wall of the throwing tube 1, it is driven by strong friction when passing through the components of the auxiliary acceleration component, and obtains secondary acceleration. Finally, it flies out of the ejection port 101 at an extremely high speed and with a stable trajectory. Heading straight for the fire source, after the fire extinguishing bomb body 3 is launched, all components and the material lifting component descend. The fire extinguishing bomb body 3 at the bottom of the storage shell 2 automatically falls to the throwing tube 1 to await the next launch, preparing for subsequent fire extinguishing operations. It realizes full automation from aiming, launching to reloading, and is particularly suitable for charging pile fire scenarios that require rapid response and continuous fire fighting. It can effectively control the spread of fire, buy valuable time for fighting initial fires, and solve the problems of delayed fire extinguishing response and insufficient accuracy of fire extinguishing bomb throwing in existing technologies. It can control the fire to the smallest area and avoid greater loss of life and property.

[0025] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9As a preferred technical solution in this embodiment, the ejection assembly includes a groove 4 formed on the throwing tube 1, a first force-bearing rod 401 slidably connected in the groove 4, a first elastic telescopic rod 402 disposed between the first force-bearing rod 401 and the inner wall of the groove 4, a straight rod 403 fixed at the end of the first force-bearing rod 401, and a push plate 404 connected to the end of the straight rod 403 away from the first force-bearing rod 401. The push plate 404 moves against the fire extinguishing projectile body 3 in the throwing tube 1. A high-strength spring is provided inside the first elastic telescopic rod 402. When an external force pushes the first force-bearing rod 401 to slide in the groove 4, the first elastic telescopic rod 402 is stretched and stores elastic potential energy. When the external force is removed, the released elastic potential energy pushes the push plate 404 to move. The setting of the groove 4 ensures the efficiency of force transmission and directional stability. Furthermore, a support plate 5 is fixedly provided on the outside of the storage shell 2, and a first motor 501 is fixedly provided on the support plate 5. The output shaft of the first motor 501 is connected to a rotating rod 502 that rotates on the support plate 5. A toggle plate 503 that moves against the first force rod 401 is fixedly provided on the rotating rod 502. Specifically, the first motor 501 is started, driving the rotating rod 502 and the actuating plate 503 to rotate. During the rotation, the actuating plate 503 pushes the first force-bearing rod 401, causing it to move along the slide groove 4. The contact surface between the first force-bearing rod 401 and the actuating plate 503 should be made of wear-resistant material or equipped with rollers to reduce wear during contact. The first elastic telescopic rod 402 is stretched, and the spring stores energy. When the actuating plate 503 rotates through a specific angle and disengages from the first force-bearing rod 401, the lock is released, and the stretched first elastic telescopic rod 402 quickly releases its stored elastic potential energy, causing the first force-bearing rod 401, the straight rod 403, and the push plate 404 to move forward at high speed. The push plate 404 accelerates the fire extinguishing bomb body 3 along the throwing tube 1, giving it an extremely high initial velocity. After ejection, the first elastic telescopic rod 402 returns to its initial position under its own restoring force, ready for the next throwing cycle. The energy storage and release are controlled by the toggle plate 503. The action is crisp and clean. Compared with the complex electronic control system, the pure mechanical transmission has a simpler structure, higher reliability and lower failure rate in the harsh environment of high temperature and smoke in the fire scene. Moreover, the motor only needs to provide stable rotational power to compress the spring, without having to bear the huge impact force at the moment of ejection. This "slow storage and fast release" mode significantly reduces the load on the motor and extends its service life.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As a preferred technical solution in this embodiment, the auxiliary acceleration component includes a support plate 6 evenly arranged in a circle on the throwing tube 1, a rotating rod 601 rotatably connected to the support plate 6, a friction wheel 602 fixedly arranged on the rotating rod 601, and a movable bevel gear 603 fixedly arranged on the rotating rod 601. The movable bevel gears 603 on two adjacent rotating rods 601 mesh with each other, and each support plate 6 includes two support plates fixedly connected to the throwing tube 1. Furthermore, the auxiliary acceleration assembly also includes a second elastic telescopic rod 7 fixed on the storage shell 2, a rack plate 701 connected to one end of the second elastic telescopic rod 7 away from the storage shell 2 via a connecting plate, and a second force-bearing rod 702 fixedly connected to the other end of the rack plate 701. The actuating plate 503 moves against the second force-bearing rod 702. One of the rotating rods 601 of the auxiliary acceleration assembly is provided with a movable gear 6011 that meshes with the rack plate 701. Specifically, when the first motor 501 starts, the actuating plate 503 on the rotating rod 502 will also abut against the second force rod 702. During this period, the second elastic telescopic rod 7 is stretched and stores elastic potential energy. The contact surface between the second force rod 702 and the actuating plate 503 also needs to be provided with a wear-resistant surface or roller to reduce wear. At the same time or slightly after the actuating plate 503 disengages from the first force rod 401 to complete the ejection action, the actuating plate 503 will also disengage from the second force rod 702. The movement of the second force rod 702 drives the rack plate 701 to move forward. The linear movement of the rack plate 701 meshes with the movable gear 6011 on one of the rotating rods 601, driving the rotating rod 601 to start rotating. Since all the rotating rods 601 mesh with each other through the movable bevel gear 603, the rotation of one rotating rod 601 will drive all the rotating rods 601 on the circumference to rotate synchronously. The friction wheel 602 fixed on the rotating rod 601 will also rotate accordingly. At high speed, the fire extinguishing projectile body 3, which has been given an initial velocity by the ejection assembly, moves forward along the inner wall of the throwing tube 1. When the fire extinguishing projectile body 3 enters the area of ​​the friction wheel 602, the high-speed rotating friction wheel 602 applies friction from all sides, giving the fire extinguishing projectile body 3 a secondary acceleration, enabling it to obtain a higher exit velocity, effectively overcoming air resistance, significantly increasing the throwing distance, allowing the fire extinguishing projectile to cover a farther fire source, and enabling it to fly a longer distance in a straight line, with higher throwing accuracy; moreover, multiple friction wheels 602 jointly apply a balanced forward thrust, effectively suppressing the irregular rolling of the fire extinguishing projectile body 3, ensuring that the fire extinguishing projectile can fly in a straight and stable manner; it should be noted that if a single motor is used to directly drive the friction wheel 602, at least three motors need to be set from different directions to ensure effective driving of the fire extinguishing projectile, increasing costs, while the mechanical linkage mechanism can make multiple friction wheels work synchronously, reducing the failure rate.

[0027] Reference Figure 9 and Figure 10As a preferred technical solution in this embodiment, a flared opening 8 is fixed to the front end of the auxiliary acceleration component on the inner wall of the throwing tube 1, and evenly distributed balls 801 are provided on the flared opening 8. Specifically, since the friction wheel 602 needs to be embedded inside the throwing tube 1 so that it can effectively generate friction with the fire extinguishing bomb body 3, the friction wheel 602 protrudes relative to the inner wall of the throwing tube 1. By setting the flared opening 8 at the front end of the friction wheel 602, the fire extinguishing bomb body 3 is guided to move, providing a smooth transition channel for the fire extinguishing bomb, so that it can smoothly and centrally enter the working area of ​​the friction wheel 602, avoiding the instantaneous huge resistance caused by colliding with the bomb wall, and ensuring that the fire extinguishing bomb flies out stably and at high speed.

[0028] Reference Figure 9 and Figure 11 As a preferred technical solution in this embodiment, the lifting assembly includes a lifting plate 9 slidably connected between the throwing tube 1 and the storage shell 2, and a third elastic telescopic rod 901 disposed between the lifting plate 9 and the storage shell 2. The second force rod 702 is provided with an abutment plate 7021 that movably abuts against one end of the lifting plate 9. One end of the lifting plate 9 is provided with a first inclined surface 902 that movably abuts against the abutment plate 7021. The end of the lifting plate 9 away from the first inclined surface 902 is provided with a second inclined surface 903 that movably abuts against the fire extinguishing bomb body 3 and is used to lift the fire extinguishing bomb body 3. Specifically, during the ejection preparation phase, the actuating plate 503 pushes against the second force rod 702. As the second force rod 702 moves, it drives the abutment plate 7021 to move synchronously. The abutment plate 7021 abuts against one end of the lifting plate 9, causing the lifting plate 9 to slide into the storage shell 2. The second inclined surface 903 of the lifting plate 9 pushes the fire extinguishing shell body 3 at the bottom of the storage shell 2, preventing the fire extinguishing shell body 3 at the bottom of the storage shell 2 from moving down into the throwing tube 1 and hindering the ejection of the fire extinguishing shell body 3 inside the throwing tube 1. During ejection... After the work is completed, the abutment plate 7021 no longer pushes against the lifting plate 9. The lifting plate 9 is reset under the elastic force of the third elastic telescopic rod 901. The lifting plate 9 no longer obstructs the downward movement of the fire extinguishing bomb body 3 in the storage shell 2. The fire extinguishing bomb body 3 automatically enters the throwing tube 1 for replenishment, preparing for the next fire extinguishing. The setting of the lifting plate 9 ensures that the ammunition supply channel is temporarily cut off at the moment of launch, solving the common problems of "ammunition jamming" or "interference with launch" in continuous ammunition supply systems, and ensuring the independence of each throw.

[0029] Reference Figure 1 , Figure 2 and Figure 9As a preferred technical solution in this embodiment, the throwing tube 1 is rotatably connected to the baffle 10 at the ejection port 101 via a rotating shaft. A torsion spring for driving the baffle 10 to reset and rotate is provided on the rotating shaft. A pull rope 1001 is fixedly provided on the baffle 10. The end of the pull rope 1001 away from the baffle 10 passes through the support plate 5 and is fixedly connected to the lifting plate 9. A pulley for guiding the pull rope 1001 and reducing wear should be provided on the outside of the throwing tube 1 or the support plate 5. Specifically, when the lifting plate 9 slides into the storage shell 2, it applies a pulling force to the pull rope 1001. The pull rope 1001 pulls the baffle 10, causing the baffle 10 to deflect around the pivot, thus preventing the baffle 10 from obstructing the ejection of the fire extinguishing bomb body 3 inside the throwing tube 1. After the fire extinguishing bomb is fired, the baffle 10 is no longer pulled by the pull rope 1001 and will flip and reset under the action of the torsion spring, sealing the ejection port 101 again. This prevents external impurities from entering the throwing tube 1 during normal placement and affecting the ejection of the fire extinguishing bomb, ensuring unobstructed trajectory and providing daily protection.

[0030] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention also discloses a modular fire extinguishing grenade throwing device for charging piles, including the aforementioned throwing component, and further including a base 11 disposed on the outside of the charging pile, a second motor 111 fixed on the base 11, a rotating seat 112 connected to the output shaft of the second motor 111, a fixed rod 113 fixed on the rotating seat 112 and movably connected to the bottom of the throwing tube 1 via a pin, and an electric push rod 114 fixed on the rotating seat 112 and movably connected to the bottom of the throwing tube 1 via a pin. The height of the electric push rod 114 when retracted is greater than the height of the fixed rod 113. A monitoring and control module is also disposed on the base 11. The monitoring and control module includes a control module for controlling the first motor 501, the second motor 111 and the electric push rod 114, and a camera and sensor electrically connected to the control module for monitoring the fire. Specifically, the base 11 is fixed near the charging pile, requiring no large-scale modification of the parking lot, making it convenient to implement and suitable for widespread adoption. The second motor 111 is mounted on the base 11, with its output shaft connected to the rotating seat 112. The upper ends of the fixed rod 113 and the electric push rod 114 are movably connected to the bottom of the throwing tube 1 via pins, forming a two-degree-of-freedom gimbal structure. The second motor 111 drives the rotating seat 112 to rotate horizontally, thereby causing the entire throwing tube 1 to sweep horizontally. The extension and retraction of the electric push rod 114 directly changes the pitch angle of the throwing tube 1. Working in tandem, the ejection port 101 of the throwing tube 1 can be precisely aimed at a fire source in any direction. The monitoring and control module generally includes a camera with infrared thermal imaging capabilities, multiple sensors, and a core control module. The sensors can be temperature and smoke sensors. These sensors continuously monitor the environment around the charging pile. Once the camera captures abnormal high temperature or open flame through image recognition and thermal imaging analysis, or the sensors detect smoke or a sudden rise in temperature, the control module will immediately analyze this information comprehensively, accurately determine the location and scale of the fire, and automatically generate a fire extinguishing command to launch fire extinguishing bombs.

[0031] This invention also discloses a method for using a modular fire extinguishing grenade throwing device for charging piles, which includes the following steps: S1: Fire Monitoring and Location Phase The monitoring and control module detects the fire situation in real time through cameras and sensors. After determining the location of the fire source, the control module starts the second motor 111 and the electric push rod 114. The output shaft of the second motor 111 controls the rotating seat 112 to rotate, causing the throwing tube 1 to rotate horizontally. At the same time, the electric push rod 114 extends and retracts to adjust the pitch angle of the throwing tube 1, so that the ejection port 101 is accurately aligned with the fire source. S2: Catapult preparation phase: After the angle adjustment is completed, the first motor 501 starts, and its output shaft drives the rotating rod 502 and the actuating plate 503 to rotate. When the actuating plate 503 rotates, it pushes the first force rod 401 and the second force rod 702. When the first force-bearing rod 401 moves under force, it stretches the first elastic telescopic rod 402 to store energy. When the first force-bearing rod 401 moves, the push plate 404 moves synchronously. The fire extinguishing bomb body 3 in the throwing tube 1 slides down to the push plate 404 in the inclined throwing tube 1. When the second force-bearing rod 702 moves under force, it compresses the second elastic telescopic rod 7 to store energy. When the second force-bearing rod 702 moves, it applies a pushing force to the lifting plate 9 through the abutment plate 7021, causing the lifting plate 9 to slide into the storage shell 2. When the lifting plate 9 moves, it supports the fire extinguishing bomb body 3 at the bottom of the storage shell 2 to prevent it from falling and interfering with the fire. When the lifting plate 9 moves, it applies a pulling force to the baffle 10 through the pull rope 1001, causing the baffle 10 to deflect around the pivot, and the baffle 10 no longer blocks the ejection port 101. S3: Ejection Execution Phase: As the rotating rod 502 rotates, the actuating plate 503 no longer abuts against and pushes the first force-bearing rod 401, and the first elastic telescopic rod 402 releases energy, propelling the fire extinguishing bomb body 3 out of the throwing tube 1 at high speed; After the fire extinguishing bomb body 3 is ejected, the actuating plate 503 no longer pushes against the second force rod 702. The second elastic telescopic rod 7 releases energy, causing the second force rod 702 and the rack plate 701 to reset. When the rack plate 701 resets, it meshes with the movable gear 6011 on the rotating rod 601. The rotating rod 601 rotates and drives the other rotating rods 601 to rotate through the meshing between the movable bevel gears 603. Each rotating rod 601 drives the friction wheel 602 to rotate, thereby driving the fire extinguishing bomb body 3 to move inside the throwing tube 1 through friction, obtaining secondary acceleration, and finally flying out of the throwing tube 1 at an extremely high speed. S4: Automatic Reload Phase After a fire extinguishing shell 3 is fired, the first force rod 401 and the second force rod 702 are both reset. The abutment plate 7021 on the second force rod 702 no longer pushes the lifting plate 9. The lifting plate 9 is reset under the elastic force of the third elastic telescopic rod 901. The lowermost fire extinguishing shell 3 in the storage shell 2 automatically falls into the throwing tube 1 to replenish the material, preparing for the next launch.
