[0003]目前，市面上的高层消防无人机抛投灭火弹装置存在明显技术缺陷，现有装置的抛投机构多为固定角度设计，灭火弹仅能沿垂直或单一方向抛投，无法根据火情高度灵活调整抛投角度：低高度火情（如10-30米）需近距离垂直抛投以确保灭火弹精准落地，而高高度火情（如50米以上）受空气阻力、风力影响，垂直抛投易导致灭火弹偏离起火点；同时，不同楼层起火位置（如窗口、阳台、楼道）对抛投角度的需求差异显著，固定角度设计无法适配多样化火情场景，部分改进型装置虽尝试通过调整无人机飞行姿态改变抛投角度，但悬停状态下调整姿态易导致无人机失稳，不仅降低抛投精准度，还可能引发无人机坠毁等安全风险；且姿态调整响应滞后，难以快速适配动态变化的火情，因此急需改进
本装置通过设置有调角机构，从而使得无人机能够在悬停的状态下来调节灭火弹的抛投角度，从而使得本装置能够满足在不同高度下火情的灭火需求，进而一定程度上提升本装置的适配性。

Abstract
Description
Technical Field
[0001] This invention relates to the field of aviation equipment technology, and in particular to an automatic fire-extinguishing bomb dropping device for high-rise fire-fighting drones. Background Technology
[0002] With rapid urbanization and a surge in the number of high-rise buildings, high-rise fires have become a major challenge in firefighting due to their rapid spread, limited rescue access, and difficulties in evacuation. Traditional high-rise firefighting relies on equipment such as ladders and fire hoses, but ladders have limited operating height and cannot cover super high-rise buildings; fire hoses experience rapid water pressure decay, resulting in insufficient range for high-rise firefighting and are susceptible to wind-induced accuracy issues. Firefighting drones with automatic fire-fighting bomb delivery systems, with their advantages of flexibility, rapid response, and unrestricted operating height, have become core equipment for high-rise fire rescue. Their delivery accuracy and adaptability directly determine firefighting efficiency and rescue effectiveness.
[0003] Currently, existing high-rise fire-fighting drones that drop fire extinguishing bombs have significant technical flaws. Most existing devices use a fixed-angle design for their dropping mechanisms, allowing fire extinguishing bombs to be dropped only vertically or in a single direction. They cannot flexibly adjust the dropping angle according to the fire's height. For low-altitude fires (e.g., 10-30 meters), close-range vertical dropping is necessary to ensure accurate landing. However, for high-altitude fires (e.g., above 50 meters), air resistance and wind can cause vertical dropping to deviate from the fire's origin. Furthermore, the required dropping angle varies significantly depending on the location of the fire on different floors (e.g., windows, balconies, corridors). Fixed-angle designs cannot adapt to diverse fire scenarios. While some improved devices attempt to change the dropping angle by adjusting the drone's flight attitude, adjusting the attitude while hovering can cause the drone to become unstable, reducing dropping accuracy and potentially leading to crashes. Moreover, the attitude adjustment response is slow, making it difficult to quickly adapt to dynamically changing fire conditions. Therefore, improvements are urgently needed. Summary of the Invention

[0034] Reference Figures 1 to 11 The present invention provides a further description of an embodiment of an automatic fire-extinguishing bomb-dropping device for high-rise firefighting drones.
[0035] An automatic fire extinguishing bomb dropping device for high-rise firefighting drones includes a support plate 1 and a control device 2 fixedly mounted on the support plate 1. The support plate 1 has two mounting sections for mounting the support plate 1 onto the drone. Each mounting section includes: a mounting plate 7, mounted on the drone; and a connecting rod 8, fixedly mounted on the mounting plate 7. A fixing sleeve 9 is fixedly mounted on the connecting rod 8, and the fixing sleeve 9 is detachably fixedly connected to the support plate 1. It should be noted that the detachable connection between the fixing sleeve 9 and the support plate 1 makes assembly and disassembly convenient, requiring no special tools, and allows for quick switching between multiple drones, improving emergency deployment efficiency. In use, the device is simply mounted onto the drone via the mounting plate 7.
[0036] The support plate 1 has an adjustment groove 3, and roller tracks 4 are provided on both sides of the adjustment groove 3. The support plate 1 is provided with a sliding plate 5 that is slidably connected to the adjustment groove 3. Multiple balls 41 are rolled on the sliding plate 5 and are slidably connected to the roller tracks 4. By providing the balls 41, the resistance encountered by the sliding plate 5 when moving is greatly reduced, thereby reducing the impact on the drone when hovering to a certain extent.
[0037] Two symmetrically distributed longitudinal plates 6 are fixedly mounted on the sliding carrier plate 5. A throwing mechanism for throwing fire extinguishing bombs is arranged between the two longitudinal plates 6. The throwing mechanism includes: a throwing cylinder 18, fixedly mounted on the mounting sleeve 17, with two symmetrically distributed internal grooves 19 on the inner wall of the throwing cylinder 18, and two symmetrically distributed throwing slots 20 in the internal grooves 19; a feeding port 21 is provided on the throwing cylinder 18; and a feeding cylinder 22 is mounted on the throwing cylinder 18 and detachably fixedly connected to the throwing cylinder 18. This arrangement allows the feeding cylinder 22 to quickly replenish bombs, and a single cylinder can continuously throw multiple bombs. Supports continuous fire extinguishing operations. The feeding cylinder 22 is used to feed materials into the throwing cylinder 18 through the feeding port 21. The pusher block 23 is slidably set in the built-in groove 19. The pusher block 23 is used to throw the fire extinguishing bombs in the throwing cylinder 18. The pusher block 23 has two symmetrically distributed first limiting grooves 24. The surface of the pusher block 23 with the first limiting grooves 24 also has a second limiting groove 25. The second limiting groove 25 is connected to the first limiting groove 24 and is perpendicular to the first limiting groove 24. The surface of the pusher block 23 away from the axis of the throwing cylinder 18 has a guide groove 26. The limiting guide part is located in the built-in groove 19. The limiting guide part is used to guide and limit the movement of the pusher block 23. The limiting guide part includes: two fixing blocks 39, which are symmetrically distributed in the built-in groove 19. The fixing blocks 39 are fixedly connected to the throwing tube 18 and slidably connected to the first limiting groove 24 and the second limiting groove 25; and a guide strip 40, which is located in the built-in groove 19 and fixedly connected to the throwing tube 18. The guide strip 40 is slidably connected to the third limiting groove 28.
[0038] The launching unit, located inside the throwing tube 18, is used to move the pusher block 23 to throw fire extinguishing shells. The launching unit includes: an L-shaped block 34 slidably disposed within the throwing groove 20, which pushes the pusher block 23 to slide within the internal groove 19; the L-shaped block 34 is made of magnetic material; an electromagnet 35 located inside the throwing tube 18 and detachably fixed to it, electrically connected to the control device 2, which attracts the L-shaped block 34; and a launching spring 36 located within the throwing groove 20, with its ends respectively touching the inner wall of the throwing tube 18. The L-shaped block 34 is fixedly connected, and the launching spring 36 is in a stretched state when the L-shaped block 34 is attracted by the electromagnet 35. The electric push rod 37 is located in the built-in groove 19 and is fixedly connected to the throwing tube 18. The electric push rod 37 is electrically connected to the control device 2. The electric push rod 37 is used to push the L-shaped block 34 to re-contact the electromagnet 35 after the fire extinguishing bullet is launched. The output end of the electric push rod 37 is fixedly provided with a buffer pad 38. The buffer pad 38 can reduce the impact force when the output end of the electric push rod 37 contacts the L-shaped block 34, reduce the collision wear of the components, and extend the service life to a certain extent.
[0039] The upper part is set inside the throwing tube 18. The upper part includes: a hydraulic push rod 32, which is fixedly set inside the throwing tube 18 and electrically connected to the control device 2; and an upper push block 33, which is slidably set inside the throwing tube 18 and fixedly connected to the output end of the hydraulic push rod 32.
[0040] The auxiliary part has two sets, and the two sets of auxiliary parts are symmetrically arranged on the throwing tube 18. The auxiliary part includes: a support tube 27, which is fixedly arranged on the throwing tube 18, and a plurality of evenly distributed third limiting grooves 28 are opened in the support tube 27; a sliding plate 29, which is slidably arranged in the support tube 27, and a plurality of connecting blocks 30 are fixedly arranged on the sliding plate 29. The connecting blocks 30 are slidably connected to the third limiting grooves 28. When the sliding plate 29 is not subjected to external force, the connecting blocks 30 stay at the end of the third limiting groove 28 near the axis of the throwing tube 18; and an internal spring 31, which is located in the support tube 27 and is always in a compressed state. The end of the internal spring 31 near the sliding plate 29 abuts against the surface of the sliding plate 29.
[0041] In use, the fire extinguishing bomb in the loading cylinder 22 falls into the throwing cylinder 18 due to gravity. Then, the control device 2 controls the hydraulic push rod 32 to start, which causes the loading push block 33, which is fixedly connected to the hydraulic push rod 32, to push the fire extinguishing bomb towards the push block 23 until the fire extinguishing bomb contacts the push block 23 and continuously applies force to the push block 23. This causes the push block 23 to drive the sliding plate 29 in contact with it to slide into the support cylinder 27 until the gap between the two push blocks 23 allows the fire extinguishing bomb to pass through, thus completing the loading operation. Then, the control device 2 controls the hydraulic push rod 32 to retract, which causes the loading push block 33, which is fixedly connected to the hydraulic push rod 32, to slide back to its original position. At this time, the fire extinguishing bomb is loaded. The fire extinguishing bomb inside the tube 22 will fall back into the throwing tube 18. At the same time, the pusher blocks 23 on both sides lose the force of the fire extinguishing bomb. The compressed built-in spring 31 in the support tube 27 pushes the sliding plate 29 to slide in the direction of the axis of the throwing tube 18 until the connecting block 30 fixedly connected to the sliding plate 29 abuts against the end of the third limiting groove 28 near the axis of the throwing tube 18, so that the sliding plate 29 pushes the pusher block 23 to reset. Then, the electromagnet 35 is de-energized by the control device 2. At this time, the L-shaped block 34 attracted by the electromagnet 35 slides in the built-in groove 19 under the force of the launching spring 36, thereby pushing the fire extinguishing bomb to slide in the built-in groove 19, thus launching the fire extinguishing bomb. After the fire extinguishing grenade is launched, the L-shaped block 34 loses the attraction force of the electromagnet 35 and completes the throwing action. Then, the control device 2 activates the electric push rod 37. The output end of the electric push rod 37 extends and pushes the L-shaped block 34 towards the electromagnet 35 until the L-shaped block 34 moves back to the position of contact with the electromagnet 35. Then, the control device 2 controls the electromagnet 35 to be energized, so that the L-shaped block 34 is attracted again. The launching spring 36 is stretched and stored again, waiting for the next throwing operation. The electric push rod 37 then retracts and resets, which is convenient for the next launching operation of the fire extinguishing grenade.
[0042] This device is equipped with a launching mechanism, which allows it to launch fire extinguishing projectiles without relying on their own weight. This eliminates the need for the drone to hover above the fire when launching the projectiles, thus preventing the drone from being burned and ensuring its safety to a certain extent when launching fire extinguishing projectiles.
[0043] The longitudinal plate 6 is provided with an angle adjustment mechanism for adjusting the angle of the fire extinguishing bombs thrown by the throwing mechanism. The angle adjustment mechanism includes: a second motor 13, which is fixedly installed on the longitudinal plate 6 and electrically connected to the control device 2; and a drive gear 14, which is fixedly installed at the output end of the second motor 13. An angle adjustment section, located on the longitudinal plate 6, is used to adjust the angle at which the fire extinguishing bomb is thrown by the throwing mechanism. The angle adjustment section includes: an angle adjustment shaft 15, rotatably mounted on the longitudinal plate 6; and a driven gear 16, fixedly mounted at the end of the angle adjustment shaft 15, meshing with a driving gear 14. The diameter of the driven gear 16 is larger than the diameter of the driving gear 14. By using the engagement of the driving gear 14 and the driven gear 16, the throwing angle is adjusted, allowing the fire extinguishing bomb's throwing angle to be steplessly adjusted from 0-60° to suit different floors and fire locations at varying distances. Simultaneously, the throwing angle of the fire extinguishing bomb is locked and stable, preventing drift under wind resistance and ensuring a consistent trajectory for each throw. An installation sleeve 17 is fixedly mounted at the end of the angle adjustment shaft 15 furthest from the driven gear 16.
[0044] The fire extinguishing bombs are accurately launched to the fire location, improving the accuracy of the device's fire extinguishing bomb throwing. Furthermore, the throwing angle of the throwing mechanism can be adjusted according to the height and horizontal position of the fire point. Specifically, the control device 2 controls the second motor 13 to start, which in turn drives the drive gear 14, fixedly connected to the output end of the second motor 13, to rotate. Through the meshing transmission between the drive gear 14 and the driven gear 16, the angle-adjusting shaft 15, fixedly connected to the driven gear 16, rotates, which in turn drives the mounting sleeve 17, fixedly connected to the angle-adjusting shaft 15, to rotate. This causes the throwing cylinder 18, fixed on the mounting sleeve 17, to rotate by a certain angle, thereby adjusting the throwing angle of the fire extinguishing bombs thrown by the throwing mechanism.
[0045] This device is equipped with an angle adjustment mechanism, which allows the drone to adjust the throwing angle of the fire extinguishing bomb while hovering, thereby meeting the fire extinguishing needs at different altitudes and improving the adaptability of the device.
[0046] The support plate 1 is provided with an adjustment part for adjusting the position of the sliding support plate 5. The adjustment part includes: a first motor 10, which is disposed on the support plate 1 and fixedly connected to the support plate 1, and the first motor 10 is electrically connected to the control device 2; an adjustment screw 11, which is located in the adjustment groove 3, and the end of the adjustment screw 11 near the first motor 10 is fixedly connected to the output end of the first motor 10, and the end of the adjustment screw 11 away from the first motor 10 is rotatably connected to the support plate 1, and the adjustment screw 11 is threadedly connected to the sliding support plate 5; and a limiting rod 12, which is located in the adjustment groove 3, and the end of the limiting rod 12 is fixedly connected to the support plate 1, and the limiting rod 12 is slidably connected to the support plate 1.
[0047] Before launching the fire extinguishing projectile, the position of the launching mechanism can be adjusted according to the location of the fire point. The specific operation is as follows: the first motor 10 is started by the control device 2, which causes the adjusting screw 11, which is fixedly connected to the output end of the first motor 10, to rotate. Through the threaded transmission between the adjusting screw 11 and the sliding plate 5, the sliding plate 5 slides on the bearing plate 1, thereby causing the longitudinal plate 6 set on the sliding plate 5 to drive the throwing mechanism to move, thereby adjusting the position of the throwing mechanism to launch the fire extinguishing projectile.
[0048] This device is equipped with an adjustment unit, which allows the device to adjust the position of the fire extinguishing bombs launched by the throwing mechanism. This enables the drone to throw the fire extinguishing bombs to different positions while hovering, without the need for the drone to move to throw the fire extinguishing bombs, thereby reducing the drone's energy consumption to a certain extent.
[0049] Working principle: During use, the fire extinguishing bomb in the loading cylinder 22 falls into the throwing cylinder 18 due to gravity. Then, the hydraulic push rod 32 is activated by the control device 2, which causes the loading push block 33, which is fixedly connected to the hydraulic push rod 32, to push the fire extinguishing bomb towards the push block 23 until the fire extinguishing bomb contacts the push block 23 and continuously applies force to the push block 23. This causes the push block 23 to drive the sliding plate 29 in contact with it to slide into the support cylinder 27 until the gap between the two push blocks 23 allows the fire extinguishing bomb to pass through, thus completing the loading operation. After that, the control device... When the hydraulic push rod 32 is retracted, the upper push block 33, which is fixedly connected to the hydraulic push rod 32, slides to its original position. At this time, the fire extinguishing bomb in the feeding cylinder 22 will fall into the throwing cylinder 18 again. Meanwhile, the push blocks 23 on both sides lose the force of the fire extinguishing bomb. The compressed built-in spring 31 in the support cylinder 27 pushes the sliding plate 29 to slide in the direction of the axis of the throwing cylinder 18 until the connecting block 30, which is fixedly connected to the sliding plate 29, abuts against the end of the third limiting groove 28 near the axis of the throwing cylinder 18, thereby causing the sliding plate 29 to push the push block 23 to reset. Then, the electromagnet 35 is de-energized by the control device 2. At this time, the L-shaped block 34 attracted by the electromagnet 35 slides in the built-in groove 19 under the force of the launching spring 36, thereby pushing the fire extinguishing bullet to slide in the built-in groove 19 and launching the fire extinguishing bullet.
[0050] Before launching the fire extinguishing bomb, the position of the launching mechanism can be adjusted according to the location of the fire point. The specific operation is as follows: the first motor 10 is started by the control device 2, which causes the adjusting screw 11, which is fixedly connected to the output end of the first motor 10, to rotate. Through the threaded transmission between the adjusting screw 11 and the sliding plate 5, the sliding plate 5 slides on the bearing plate 1, which causes the longitudinal plate 6 set on the sliding plate 5 to drive the throwing mechanism to move, thereby adjusting the position of the throwing mechanism to launch the fire extinguishing bomb.
[0051] The fire extinguishing bombs are accurately launched to the fire location, improving the accuracy of the device's fire extinguishing bomb throwing. Furthermore, the throwing angle of the throwing mechanism can be adjusted according to the height and horizontal position of the fire point. Specifically, the control device 2 controls the second motor 13 to start, which in turn drives the drive gear 14, fixedly connected to the output end of the second motor 13, to rotate. Through the meshing transmission between the drive gear 14 and the driven gear 16, the angle-adjusting shaft 15, fixedly connected to the driven gear 16, rotates, which in turn drives the mounting sleeve 17, fixedly connected to the angle-adjusting shaft 15, to rotate. This causes the throwing cylinder 18, fixed on the mounting sleeve 17, to rotate by a certain angle, thereby adjusting the throwing angle of the fire extinguishing bombs thrown by the throwing mechanism.
[0052] After the fire extinguishing grenade is launched, the L-shaped block 34 loses the attraction force of the electromagnet 35 and completes the throwing action. Then, the control device 2 activates the electric push rod 37. The output end of the electric push rod 37 extends and pushes the L-shaped block 34 towards the electromagnet 35 until the L-shaped block 34 moves back to the position of contact with the electromagnet 35. Then, the control device 2 controls the electromagnet 35 to be energized, so that the L-shaped block 34 is attracted again. The launching spring 36 is stretched and stored again, waiting for the next throwing operation. The electric push rod 37 then retracts and resets, which is convenient for the next launching operation of the fire extinguishing grenade.
