A mobile fire-fighting robotic arm with glass-breaking capabilities

Abstract

This invention relates to the field of fire-fighting equipment technology and discloses an airborne fire-fighting robotic arm with glass-breaking function. It includes a mounting frame, an electromagnetic glass-breaker fixedly connected to the inner wall of the mounting frame, a high-pressure water gun fixedly connected to the top of the electromagnetic glass-breaker, and a window-breaking mechanism fixedly installed on the inner wall of the electromagnetic glass-breaker. The mounting frame is installed on the bottom of an external drone. Firefighters operate the drone to launch window-breaking projectiles through the electromagnetic glass-breaker to shatter the glass, allowing dense smoke in high-rise buildings to be quickly expelled, preventing trapped occupants from inhaling smoke or suffering from oxygen deprivation. During the launch of the window-breaking projectiles, the center of gravity component shifts the electromagnetic glass-breaker's center of gravity to the left, applying a downward force to suppress drone tilting. This effectively prevents the drone from tilting significantly due to smoke impact, avoiding drone imbalance and ensuring the launch tube can be quickly adjusted to target the next piece of glass to be broken.

Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to an airborne fire-fighting robotic arm with glass-breaking function. Background Technology

[0002] Airborne fire extinguishing robotic arms with glass-breaking capabilities are special robotic arm systems that integrate glass-breaking devices and fire extinguishing actuators. By being mounted on mobile platforms such as aerial ladder trucks, fire ladder trucks, and fire-fighting drones, they can quickly break through glass curtain walls and closed windows of high-rise buildings, creating a direct channel for fire extinguishing agents to reach indoor fire sources and providing a more solid guarantee for urban fire safety.

[0003] When using drones for window-breaking rescue, as the drone's window breaker launches its projectile to break the glass, the dense smoke from the fire scene will rapidly spread outwards from that point. However, it takes time for the drone to move away from the breaking point. The high-speed airflow from the spreading smoke may impact the drone's blades, potentially causing the side of the drone's blades closest to the breaking point to rise, resulting in the drone tilting. This tilt makes it difficult for the drone to quickly adjust its level after breaking the window and move on to the next breaking point, thus affecting rescue efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an airborne fire extinguishing robotic arm with glass-breaking function, including a mounting frame, an electromagnetic glass breaker fixedly connected to the inner wall of the mounting frame, a high-pressure water gun fixedly connected to the top of the electromagnetic glass breaker, and further including:

[0005] The window breaking mechanism is fixedly installed on the inner wall of the electromagnetic glass breaker.

[0006] An adjustment mechanism is slidably installed on the inner wall of the electromagnetic glass breaker.

[0007] A counterweight mechanism is slidably mounted at the bottom of the electromagnetic glass breaker.

[0008] In use, the mounting bracket is installed on the bottom of an external drone. Firefighters control the drone to raise the electromagnetic glass breaker and move it to the location where the window needs to be broken. The glass is then broken by launching projectiles through the window-breaking mechanism, causing the thick smoke inside the high-rise building to spread outward.

[0009] Preferably, the window-breaking mechanism includes:

[0010] The pushing component is fixedly installed on the inner wall of the electromagnetic glass breaker;

[0011] The launching component is slidably disposed on the inner wall of the electromagnetic glass breaker;

[0012] When the drone moves to the window-breaking position, it activates the propulsion component to move the projectile into the launch component, and then activates the electromagnetic glass breaker to generate an alternating magnetic field, which accelerates the projectile out and breaks the glass.

[0013] Preferably, the adjustment mechanism includes:

[0014] The center of gravity component is slidably disposed on the inner wall of the electromagnetic glass breaker.

[0015] The jet assembly is fixedly mounted at the bottom of the electromagnetic glass breaker by a fastener.

[0016] The fasteners include two pneumatic sleeves fixedly connected to the bottom of the electromagnetic glass breaker, and spring pneumatic rods are slidably connected to the inner walls of the two pneumatic sleeves.

[0017] When the component is pushed to move, the center of gravity component is also pushed to move, adjusting the center of gravity of the electromagnetic glass breaker. When the component is pushed back to its original position, the jet component is squeezed, causing gas to be ejected from the jet component.

[0018] Preferably, the counterweight mechanism includes:

[0019] The hydraulic component is slidably mounted at the bottom of the electromagnetic glass breaker.

[0020] Synchronization component, which is slidably disposed on the inner wall of hydraulic component;

[0021] After multiple projectiles are launched, the weight on the right side of the electromagnetic glass breaker decreases. Each time the center of gravity component returns to its original position, it pushes the synchronization component back to its original position by a certain distance, so that the weight on the left and right sides of the electromagnetic glass breaker tends to be uniform.

[0022] Preferably, the pushing component includes an electric telescopic rod fixedly connected to the inner wall of the electromagnetic glass breaker, a pushing block slidably connected to the inner wall of the electromagnetic glass breaker, and the output end sidewall of the electric telescopic rod being fixedly connected to the sidewall of the pushing block.

[0023] Preferably, the launching assembly includes six window-breaking projectiles slidably connected to the inner wall of the electromagnetic glass breaker, and a launching tube is fixedly connected to the inner wall of the electromagnetic glass breaker, with the inner wall of the launching tube slidably connected to the outer wall of the window-breaking projectiles.

[0024] The system involves mounting a frame on the bottom of an external drone. When a fire breaks out in a high-rise building and glass breaking is required, firefighters connect the external fire hose to a high-pressure water gun. Then, the firefighters operate the drone to fly to the location where the glass needs to be broken, causing the electromagnetic glass breaker to rise. Once the drone is in position, it retracts an electric telescopic rod, which moves a push block towards the launch tube. As the push block moves, it pushes the window-breaking projectile into the launch tube. The electromagnetic glass breaker is then activated, creating an alternating magnetic field inside the launch tube, which rapidly fires the window-breaking projectile. The projectile impacts the glass, shattering it and allowing the dense smoke in the high-rise building to be quickly expelled, preventing trapped occupants from inhaling smoke or suffering from oxygen deprivation.

[0025] Preferably, the center of gravity component includes a pusher frame slidably connected to the inner wall of the electromagnetic glass breaker, the top of the pusher frame being fixedly connected to the bottom of the pusher block, and a counterweight block being slidably connected to the bottom of the electromagnetic glass breaker;

[0026] As the pusher moves towards the launch tube, it also moves the pusher frame until it contacts the counterweight. The pusher frame continues to move, pushing the counterweight towards the left side of the electromagnetic glass breaker. This shifts the center of gravity of the electromagnetic glass breaker to the left. When the dense smoke rapidly spreading outward from the glass-breaking location impacts the left blades of the drone, potentially causing the drone to rise on that side and resulting in lift imbalance, shifting the center of gravity of the electromagnetic glass breaker to the left applies a downward gravitational force to the left side, counteracting the lift force on the left side of the drone. This suppresses the drone's tilt and reduces its tilt angle, effectively preventing the drone from tilting too much when impacted by dense smoke. This prevents the drone from becoming unbalanced and making it difficult to quickly adjust the launch tube to aim at the next piece of glass to be broken, thus accelerating rescue efficiency.

[0027] Preferably, the jet assembly includes a jet pipe that extends through the inner wall of the pneumatic sleeve, and a sealing piston ring is slidably connected to the inner wall of both pneumatic sleeves.

[0028] The side walls of the two sealing piston rings are fixedly connected to the side walls of the two spring gas rods. The two spring gas rods are in a compressed state. The two spring gas rods are fixedly connected with sealing rings. The outer walls of the two sealing piston rings are fixedly connected with sealing rings to prevent gas from overflowing.

[0029] When the pusher moves toward the counterweight, it separates from the spring-pneumatic rod. The spring-pneumatic rod's rebound force is released, causing the sealing piston ring to return to its original position, allowing the jet pipe to leak out. External gas then enters the pneumatic sleeve through the jet pipe. When the window-breaking projectile is fired, the electric telescopic rod will extend again, moving the pusher away from the launch tube. At this time, the left side of the pusher is far from the counterweight and has not yet contacted the counterweight. The pusher will first contact the spring-pneumatic rod, thereby pushing the spring-pneumatic rod to move and compress it.

[0030] The spring-loaded pneumatic rod moves the sealing piston ring. When the sealing piston ring covers the jet pipe, the right side of the spring-loaded pneumatic rod is in a sealed state. At this time, the spring-loaded pneumatic rod compresses the gas inside the pneumatic sleeve, generating high pressure. As the sealing piston ring continues to move, the jet pipe is exposed again. The high-pressure gas inside the pneumatic sleeve is then quickly ejected from the jet pipe, giving the right side of the electromagnetic glass breaker an upward recoil force. This, in turn, gives the right side of the drone an upward recoil force, causing the drone to tilt. When adjusting for balance, the recoil force counteracts the tilting tendency of the drone, causing its right side to rise, thus allowing the drone to balance more quickly.

[0031] Preferably, the hydraulic component includes a counterweight two slidably connected to the bottom of the electromagnetic glass breaker, a piston rod slidably connected to the inner wall of the counterweight two, the top of the piston rod being fixedly connected to the bottom of the counterweight one, hydraulic oil being provided inside the counterweight two, a sealing ring two being fixedly connected to the outer wall of the piston rod, and a sealing ring three being fixedly connected to the inner wall of the counterweight two. The inner wall of the sealing ring three is slidably connected to the outer wall of the piston rod to prevent hydraulic oil leakage.

[0032] Preferably, the synchronization component includes a ball-head spring rod disposed on the outer wall of the piston rod, and a connecting block is fixedly connected to the inner wall of the second counterweight, with the inner wall of the connecting block slidably connected to the outer wall of the ball-head spring rod.

[0033] When the first counterweight moves to the left, it drives the piston rod to move. As the piston rod continues to move, the protrusion at the top of the piston rod will lift the ball-head spring rod, allowing it to accumulate rebound force. The ball-head spring rod will then separate from the inclined surface of the second counterweight. The hydraulic oil inside the second counterweight will then fall to the right side of the piston rod. As the piston rod continues to move, the protrusion at the top of the piston rod will separate from the ball-head spring rod, and the rebound force of the ball-head spring rod will be released. It will then contact the inclined surface of the second counterweight again, blocking the flow of hydraulic oil. At this time, the first counterweight will also stop moving.

[0034] During the push-back process, when the left side of the push-back mechanism comes into contact with counterweight one again, it will push counterweight one back to its original position. Counterweight one will also drive the piston rod to move. The piston rod, through the hydraulic oil on its right side, will push counterweight two to the right, adjusting the center of gravity of the electromagnetic glass breaker. This effectively prevents the window-breaking projectile, which usually contains fire extinguishing agent, from being too heavy. After the window-breaking projectile is fired, the weight of the electromagnetic glass breaker will be reduced, causing its center of gravity to shift and affecting the balance of the drone.

[0035] The present invention has the following beneficial effects:

[0036] (1) When using this invention, the mounting bracket is installed on the bottom of the external drone. When a fire occurs in a high-rise building and glass needs to be broken, the firefighters operate the drone and launch window-breaking bullets through the electromagnetic glass breaker to break the glass, so that the dense smoke in the high-rise building can be quickly discharged to the outside, preventing trapped people from inhaling dense smoke or suffering from hypoxia and accidents. During the launch of the window-breaking bullets, the center of gravity component will push the counterweight block to move to the left side of the electromagnetic glass breaker, so that the center of gravity of the electromagnetic glass breaker is biased to the left side, which will apply a downward gravity force to counteract the upward force on the left side of the drone, thereby suppressing the tilt of the drone and effectively preventing the drone from being impacted by dense smoke, which would produce a large tilt angle and easily cause the drone to lose balance. This allows for quick adjustment of the launch tube to aim at the next piece of glass that needs to be broken, thus speeding up the rescue efficiency.

[0037] (2) In this invention, when the center of gravity component moves, it will push the spring gas rod to move, so that the spring gas rod compresses the gas in the gas sleeve, so that the gas generates high pressure until the high pressure gas is ejected from the jet pipe, which will give the right side of the electromagnetic glass breaker an upward recoil force, thereby giving the right side of the drone an upward recoil force. When the drone tilts and adjusts its balance, the recoil force will counteract the tilting trend of the drone, causing its right side to rise, thereby allowing the drone to balance faster.

[0038] (3) In this invention, when the center of gravity component moves, it will drive the piston rod to move. As the piston rod continues to move, the hydraulic oil in the counterweight block two will fall to the right side of the piston rod. During the return process of the center of gravity component, the piston rod will push the counterweight block two to the right through the hydraulic oil on its right side. This will cause the counterweight block two to move a certain distance to the right side of the electromagnetic glassbreaker after each window-breaking bullet is fired, thus adjusting the center of gravity of the electromagnetic glassbreaker. This effectively prevents the window-breaking bullet from being too heavy due to the fire extinguishing agent inside. After firing the window-breaking bullet, the weight of the electromagnetic glassbreaker will be reduced, causing its center of gravity to deflect and affecting the balance of the UAV.

[0039] (4) In this invention, when the last window-breaking bullet in the electromagnetic glass breaker is fired, the piston rod will contact the left side of the inner wall of the counterweight block two after multiple movements. At this time, when the counterweight block one drives the piston rod to move to the left side of the electromagnetic glass breaker, the piston rod will also drive the counterweight block two to move synchronously, so that the weight on the left side of the electromagnetic glass breaker increases, which can better suppress the tilt of the drone and effectively prevent the drone from tilting at a greater angle due to the impact of smoke after multiple window-breaking bullets are fired.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1, please refer to Figures 1-6 This invention relates to an airborne fire extinguishing robotic arm with glass-breaking function, comprising a mounting frame 13, an electromagnetic glass breaker 14 fixedly connected to the inner wall of the mounting frame 13, a high-pressure water gun 15 fixedly connected to the top of the electromagnetic glass breaker 14, and further comprising:

[0057] Window breaking mechanism 1 is fixedly installed on the inner wall of electromagnetic glass breaker 14;

[0058] Adjustment mechanism 2 is slidably disposed on the inner wall of electromagnetic glass breaker 14;

[0059] The counterweight mechanism 3 is slidably disposed at the bottom of the electromagnetic glass breaker 14;

[0060] In use, the mounting bracket 13 is installed on the bottom of an external drone. Firefighters control the drone to raise the electromagnetic glass breaker 14 and move it to the location where the window needs to be broken. The glass is then broken by launching a projectile through the window breaking mechanism 1, causing the thick smoke inside the high-rise building to spread outward.

[0061] Window breaking mechanism 1 includes:

[0062] Pushing component 11 is fixedly installed on the inner wall of electromagnetic glass breaker 14;

[0063] The emitting component 12 is slidably disposed on the inner wall of the electromagnetic glass breaker 14;

[0064] When the drone moves to the window break position, it pushes the projectile into the launching component 12 by activating the pushing component 11. Then, it activates the electromagnetic glass breaker 14 to generate an alternating magnetic field, which drives the projectile to accelerate out and break the glass.

[0065] Adjustment mechanism 2 includes:

[0066] The center of gravity component 21 is slidably disposed on the inner wall of the electromagnetic glass breaker 14;

[0067] The jet assembly 22 is fixedly mounted on the bottom of the electromagnetic glass breaker 14 by a fastener;

[0068] The fasteners include two pneumatic sleeves 221 fixedly connected to the bottom of the electromagnetic glass breaker 14, and spring pneumatic rods 222 are slidably connected to the inner walls of the two pneumatic sleeves 221.

[0069] When the push component 11 moves, it will push the center of gravity component 21 to move, adjusting the center of gravity of the electromagnetic glass breaker 14. When the push component 11 returns to its original position, it will squeeze the jet component 22, causing gas to be ejected from the jet component 22.

[0070] The counterweight mechanism 3 includes:

[0071] Hydraulic component 31 is slidably disposed at the bottom of electromagnetic glass breaker 14;

[0072] Synchronization component 32 is slidably disposed on the inner wall of hydraulic component 31;

[0073] After multiple projectiles are launched, the weight on the right side of the electromagnetic glass breaker 14 decreases. Each time the center of gravity assembly 21 returns to its original position, it pushes the synchronization assembly 32 back to its original position by a certain distance, so that the weight on the left and right sides of the electromagnetic glass breaker 14 tends to be uniform.

[0074] Example 2, please refer to Figures 4-12 The present invention is an airborne fire extinguishing robotic arm with glass-breaking function. Based on Example 1, the pushing component 11 includes an electric telescopic rod 111 fixedly connected to the inner wall of the electromagnetic glass breaker 14, a pushing block 112 slidably connected to the inner wall of the electromagnetic glass breaker 14, and the output end side wall of the electric telescopic rod 111 fixedly connected to the side wall of the pushing block 112.

[0075] The launching assembly 12 includes six window-breaking projectiles 121 that are slidably connected to the inner wall of the electromagnetic glass breaker 14. A launching tube 122 is fixedly connected to the inner wall of the electromagnetic glass breaker 14, and the inner wall of the launching tube 122 is slidably connected to the outer wall of the window-breaking projectiles 121.

[0076] The mounting bracket 13 is installed at the bottom of an external drone. When a fire occurs in a high-rise building and glass breaking is required, firefighters connect the external fire hose to the high-pressure water gun 15. Then, the firefighters operate the drone to fly to the location where glass breaking is needed, driving the electromagnetic glass breaker 14 to rise. After the drone moves into position, it retracts the electric telescopic rod 111, which drives the push block 112 to move towards the launch tube 122. When the push block 112 moves, it pushes the window-breaking bullet 121 into the launch tube 122. Then, the electromagnetic glass breaker 14 is activated, which generates an alternating magnetic field in the launch tube 122, causing the window-breaking bullet 121 to be launched quickly. The window-breaking bullet 121 impacts the glass, breaking it and allowing the dense smoke in the high-rise building to be quickly discharged to the outside, preventing trapped people from inhaling dense smoke or suffering from oxygen deficiency.

[0077] The center of gravity assembly 21 includes a pusher frame 211 that is slidably connected to the inner wall of the electromagnetic glass breaker 14. The top of the pusher frame 211 is fixedly connected to the bottom of the pusher block 112, and a counterweight block 212 is slidably connected to the bottom of the electromagnetic glass breaker 14.

[0078] As the pusher block 112 moves toward the launch tube 122, it also drives the pusher frame 211 to move until the pusher frame 211 contacts the counterweight block 212. The pusher frame 211 continues to move, pushing the counterweight block 212 toward the left side of the electromagnetic glass breaker 14. Figure 11 As shown, the electromagnetic glass breaker 14 is positioned with its center of gravity shifted to the left. When dense smoke rapidly spreads outward from the glass-breaking location and impacts the left blades of the drone, potentially causing the drone to rise on that side and resulting in lift imbalance, shifting the center of gravity of the electromagnetic glass breaker 14 to the left applies a downward gravitational force to the left side, counteracting the lift force on the left side of the drone. This suppresses the drone's tilt and reduces its tilt angle, effectively preventing the drone from being impacted by dense smoke and developing a large tilt angle that could cause it to lose balance. This allows for quick adjustment of the launch tube 122 to aim at the next piece of glass that needs to be broken, accelerating rescue efficiency.

[0079] The jet assembly 22 includes a jet pipe 224 that is connected through the inner wall of the pneumatic sleeve 221, and a sealing piston ring 223 is slidably connected to the inner wall of both pneumatic sleeves 221.

[0080] The side walls of the two sealing piston rings 223 are fixedly connected to the side walls of the two spring gas rods 222. The two spring gas rods 222 are in a compressed state. The two spring gas rods 222 are fixedly connected with a sealing ring. The outer walls of the two sealing piston rings 223 are fixedly connected with a sealing ring to prevent gas from overflowing.

[0081] When the pusher 211 moves towards the counterweight 212, it separates from the spring-pneumatic rod 222. The rebound force of the spring-pneumatic rod 222 is released, causing the sealing piston ring 223 to return to its original position. Figure 11 As shown, when the jet pipe 224 is leaked out, external gas will enter the pneumatic sleeve 221 through the jet pipe 224. When the window-breaking bullet 121 is launched, the electric telescopic rod 111 will be activated again to extend, so that the push block 112 is away from the launch tube 122. At this time, the left side of the push frame 211 is far away from the counterweight 212 and has not contacted the counterweight 212. The push frame 211 will first contact the spring pneumatic rod 222, thereby pushing the spring pneumatic rod 222 to move and put the spring pneumatic rod 222 in a compressed state.

[0082] The spring-loaded pneumatic rod 222 moves the sealing piston ring 223. When the sealing piston ring 223 covers the jet pipe 224, the right side of the spring-loaded pneumatic rod 222 is in a sealed state. At this time, the spring-loaded pneumatic rod 222 compresses the gas inside the pneumatic sleeve 221, causing the gas to generate high pressure. As the sealing piston ring 223 continues to move, the jet pipe 224 will be exposed again. Figure 8 As shown, the high-pressure gas inside the air pressure sleeve 221 will be quickly ejected from the jet pipe 224, giving the right side of the electromagnetic glass breaker 14 an upward recoil force, which in turn gives the right side of the drone an upward recoil force. When the drone tilts and is adjusted for balance, the recoil force will counteract the tilting trend of the drone, causing its right side to rise, thus allowing the drone to balance more quickly.

[0083] The hydraulic assembly 31 includes a second counterweight 311 slidably connected to the bottom of the electromagnetic glass breaker 14. A piston rod 312 is slidably connected to the inner wall of the second counterweight 311. The top of the piston rod 312 is fixedly connected to the bottom of the first counterweight 212. Hydraulic oil is provided inside the second counterweight 311. A second sealing ring is fixedly connected to the outer wall of the piston rod 312. A third sealing ring is fixedly connected to the inner wall of the second counterweight 311. The inner wall of the third sealing ring is slidably connected to the outer wall of the piston rod 312 to prevent hydraulic oil leakage.

[0084] The synchronization component 32 includes a ball-head spring rod 321 disposed on the outer wall of the piston rod 312, and a connecting block 322 fixedly connected to the inner wall of the counterweight 311. The inner wall of the connecting block 322 is slidably connected to the outer wall of the ball-head spring rod 321.

[0085] When counterweight 212 moves to the left, such as Figure 9 As shown, this will cause the piston rod 312 to move. As the piston rod 312 continues to move, the protrusion at the top of the piston rod 312 will lift the ball-head spring rod 321, causing it to accumulate a rebound force, such as... Figure 10 As shown in position G, the ball spring rod 321 will separate from the inclined surface of the second counterweight 311, and the hydraulic oil inside the second counterweight 311 will fall to the right side of the piston rod 312, as... Figure 10As shown in the direction of F, as the piston rod 312 continues to move, the protrusion at the top of the piston rod 312 will separate from the ball spring rod 321, and the rebound force of the ball spring rod 321 will be released, and it will contact the inclined surface of the second counterweight 311 again, blocking the flow of hydraulic oil. At this time, the first counterweight 212 will also stop moving.

[0086] During the return process of the pusher 211, when its left side contacts the counterweight 212 again, it will push the counterweight 212 back to its original position. The counterweight 212 will also drive the piston rod 312 to move. The piston rod 312, through the hydraulic oil on its right side, will push the counterweight 311 to the right, adjusting the center of gravity of the electromagnetic glassbreaker 14. This effectively prevents the window-breaking bullet 121 from being too heavy due to the fire extinguishing agent inside. After the window-breaking bullet 121 is launched, it will reduce the weight of the electromagnetic glassbreaker 14, causing its center of gravity to shift and affecting the balance of the UAV.

[0087] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0088] A specific application of this embodiment is as follows: When using this invention, the mounting bracket 13 is installed at the bottom of an external drone. When a fire occurs in a high-rise building and glass breaking is required, firefighters connect the external fire hose to the high-pressure water gun 15. Then, the firefighters operate the drone to fly to the location where glass breaking is required, driving the electromagnetic glass breaker 14 to rise. When the drone moves to the position, the electric telescopic rod 111 is activated to retract, driving the push block 112 to move towards the launch tube 122. When the push block 112 moves, it will push the window breaking bullet 121 into the launch tube 122. Then, the electromagnetic glass breaker 14 is activated, causing an alternating magnetic field to be generated in the launch tube 122, which will quickly shoot out the window breaking bullet 121, causing the window breaking bullet 121 to impact the glass and break it. This allows the dense smoke in the high-rise building to be quickly discharged to the outside, preventing trapped people from inhaling dense smoke or suffering from oxygen deficiency and accidents.

[0089] As the pusher block 112 moves toward the launch tube 122, it also drives the pusher frame 211 to move until the pusher frame 211 contacts the counterweight block 212. The pusher frame 211 continues to move, pushing the counterweight block 212 toward the left side of the electromagnetic glass breaker 14. Figure 11As shown, the electromagnetic glass breaker 14 is positioned with its center of gravity shifted to the left. When dense smoke rapidly spreads outward from the glass-breaking location and impacts the left blade of the drone, it can easily cause the drone to rise on that side, resulting in lift imbalance. By shifting the center of gravity of the electromagnetic glass breaker 14 to the left, a downward gravitational force is applied to the left side, which counteracts the lift force on the left side of the drone, thereby suppressing the drone's tilt and reducing the tilt angle. This effectively prevents the drone from being impacted by dense smoke, which would cause a large tilt angle, easily leading to drone imbalance and making it difficult to quickly adjust the launch tube 122 to aim at the next piece of glass that needs to be broken, thus speeding up the rescue efficiency.

[0090] Secondly, when the pusher 211 moves towards the counterweight 212, it will separate from the spring-pneumatic rod 222, and the rebound force of the spring-pneumatic rod 222 will be released, causing the sealing piston ring 223 to return to its original position. Figure 11 As shown, when the jet pipe 224 is leaked out, external gas will enter the pneumatic sleeve 221 through the jet pipe 224. When the window-breaking bullet 121 is launched, the electric telescopic rod 111 will be activated again to extend, so that the push block 112 is away from the launch tube 122. At this time, the left side of the push frame 211 is far away from the counterweight 212 and has not contacted the counterweight 212. The push frame 211 will first contact the spring pneumatic rod 222, thereby pushing the spring pneumatic rod 222 to move and put the spring pneumatic rod 222 in a compressed state.

[0091] The spring-loaded pneumatic rod 222 moves the sealing piston ring 223. When the sealing piston ring 223 covers the jet pipe 224, the right side of the spring-loaded pneumatic rod 222 is in a sealed state. At this time, the spring-loaded pneumatic rod 222 compresses the gas inside the pneumatic sleeve 221, causing the gas to generate high pressure. As the sealing piston ring 223 continues to move, the jet pipe 224 will be exposed again. Figure 8 As shown, the high-pressure gas inside the air pressure sleeve 221 will be quickly ejected from the jet pipe 224, which will give the electromagnetic glass breaker 14 an upward recoil force on the right side, and thus give the drone an upward recoil force on the right side. When the drone tilts and adjusts its balance, the recoil force will counteract the tilting trend of the drone, causing its right side to rise, thereby allowing the drone to balance more quickly.

[0092] In this process, after the electric telescopic rod 111 extends and the push block 112 returns to its original position, the window-breaking bullet 121 inside the electromagnetic glass breaker 14 will fall due to its own weight. When it is necessary to fire the window-breaking bullet 121 again, the electric telescopic rod 111 is retracted by restarting, allowing the push block 112 to push the window-breaking bullet 121 into the launching tube 122 again, thus firing the window-breaking bullet 121. This process is repeated until all the window-breaking bullets 121 have been fired. Then, an external water pump can be started to pump water into the fire hose. Through the fire hose, the high-pressure water gun 15 will spray water to extinguish the fire.

[0093] Secondly, when counterweight 212 moves to the left, as Figure 9 As shown, this will cause the piston rod 312 to move. As the piston rod 312 continues to move, the protrusion at the top of the piston rod 312 will lift the ball-head spring rod 321, causing it to accumulate a rebound force, such as... Figure 10 As shown in position G, the ball spring rod 321 will separate from the inclined surface of the second counterweight 311, and the hydraulic oil inside the second counterweight 311 will fall to the right side of the piston rod 312, as... Figure 10 As shown in the direction of F, as the piston rod 312 continues to move, the protrusion at the top of the piston rod 312 will separate from the ball spring rod 321, and the rebound force of the ball spring rod 321 will be released, and it will contact the inclined surface of the second counterweight 311 again, blocking the flow of hydraulic oil. At this time, the first counterweight 212 will also stop moving.

[0094] During the return process of the pusher 211, when its left side contacts the counterweight 212 again, it will push the counterweight 212 back to its original position. The counterweight 212 will also drive the piston rod 312 to move. The piston rod 312, through the hydraulic oil on its right side, will push the counterweight 211 to the right. When the counterweight 212 moves to the left again, the protrusion on the outer wall of the piston rod 312 will push the ball spring rod 321 up again, allowing the hydraulic oil to enter the right side of the piston rod 312 again. This process repeats, so that after each firing of the window-breaking bullet 121, the counterweight 211 will move a distance to the right side of the electromagnetic glassbreaker 14, adjusting the center of gravity of the electromagnetic glassbreaker 14. This effectively prevents the window-breaking bullet 121 from being too heavy due to the fire extinguishing agent inside. Firing the window-breaking bullet 121 would reduce the weight of the electromagnetic glassbreaker 14, causing its center of gravity to shift and affecting the balance of the UAV.

[0095] Secondly, when the last window-breaking projectile 121 inside the electromagnetic glass breaker 14 is launched, the piston rod 312, after moving multiple times, will contact the left side of the inner wall of the second counterweight 311, such as... Figure 12 As shown, when the counterweight 212 drives the piston rod 312 to move to the left side of the electromagnetic glass breaker 14, the piston rod 312 will also drive the counterweight 311 to move synchronously, which increases the weight on the left side of the electromagnetic glass breaker 14, which can better suppress the tilt of the drone and effectively prevent the drone from tilting after multiple window-breaking bullets 121 are fired. At this time, the total weight of the electromagnetic glass breaker 14 is reduced, and the drone is more likely to be impacted by the smoke and produce a larger tilt angle.

[0096] When the fire-fighting drone lands, after the new window-breaking bullet 121 is installed, the firefighters can manually pull the second counterweight 311 to the left of the electromagnetic window breaker 14. The piston rod 312 will then squeeze the hydraulic oil to push the ball spring rod 321 upward, so that the hydraulic oil enters the second counterweight 311 and completes the reset of the second counterweight 311.
