High-altitude unmanned aerial vehicle for dry powder water-based fire extinguishing bomb

Abstract

This invention discloses a high-altitude dry powder water-based fire extinguishing bomb drone, relating to the field of drone-based fire extinguishing bomb technology. It includes a heavy-load drone body with a mounting frame fixedly connected to its bottom. Multiple placement compartments are arranged within the mounting frame. This high-altitude dry powder water-based fire extinguishing bomb drone, through the multiple placement compartments on the mounting frame and the cooperation of a moving mechanism and a clamping mechanism, enables the drone to drop multiple fire extinguishing bombs during a single flight. Simultaneously, a transmission mechanism drives adjusting plates to rotate, causing two adjusting plates to rotate forward of the mounting frame, thereby moving the fire extinguishing bombs in the placement compartments forward. This effectively balances the weight behind the mounting frame, achieving a balanced gravity area for the bombs. This enhances the stability of the drone during high-altitude bomb dropping and reduces the risk of crashes due to center of gravity shift and wind effects.

Description

Technical Field

[0001] This invention relates to the technology of drones for delivering fire extinguishing bombs, specifically to a drone for high-altitude delivery of dry powder water-based fire extinguishing bombs. Background Technology

[0002] In fire rescue scenarios, using drones to drop fire extinguishing bombs is a relatively efficient and flexible method for firefighting operations. However, existing drone-based fire extinguishing bomb technology has some significant shortcomings.

[0003] Currently, most drones can only drop a single fire extinguishing bomb during a single flight. This is mainly because their structural design lacks an effective mechanism for multiple bomb deployment and balance adjustment. When a drone carries multiple fire extinguishing bombs, its center of gravity dynamically changes as the bombs are dropped sequentially. For example, when a fire extinguishing bomb moves from the front to above the feed pipe at the rear, the weight behind the mounting frame increases, easily causing a shift in the center of gravity. Simultaneously, drones flying at high altitudes are significantly affected by external factors such as wind. Under the combined effects of a shifted center of gravity and wind, the drone's balance is easily lost, leading to crashes. This not only damages the drone equipment but also prevents the successful completion of firefighting missions, reducing the reliability and success rate of firefighting operations and failing to meet the demands for efficient and stable firefighting in actual fire rescue operations.

[0004] Therefore, developing a drone-based fire extinguishing bomb delivery technology capable of stably deploying multiple fire extinguishing bombs during a single flight, effectively solving the problem of center of gravity shift and enhancing high-altitude flight stability, is of significant practical importance. This invention addresses the problems in the existing technology by providing a drone for high-altitude delivery of dry powder water-based fire extinguishing bombs, thus overcoming the shortcomings of the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a high-altitude delivery drone for dry powder water-based fire extinguishing bombs, in order to solve the problem that existing technologies cannot stably deliver multiple fire extinguishing bombs in a single flight.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-altitude delivery drone for dry powder water-based fire extinguishing bombs, comprising a heavy-load drone body, a mounting frame fixedly connected to the bottom of the heavy-load drone body, multiple placement compartments provided within the mounting frame, a mounting ring rotatably connected to the top of the mounting frame, a drive mechanism connected to the mounting frame being driven to rotate on the outer surface of the mounting ring; a mounting bracket fixedly connected to the top of the mounting ring, a transmission block slidably connected to the mounting bracket, a moving mechanism connected to the mounting bracket being provided on the transmission block, the moving mechanism being driven to move the transmission block horizontally; a first telescopic drive member fixedly connected to the bottom of the transmission block, a clamping mechanism fixedly connected to the output end of the first telescopic drive member, the clamping mechanism being used to clamp and fix the fire extinguishing bomb body;

[0007] The mounting frame has two rotatably connected adjustment plates. Each adjustment plate is connected to a transmission mechanism that is also connected to the mounting frame. Each adjustment plate has a fixed placement chamber. The transmission mechanism is used to drive the adjustment plates to rotate. A feeding pipe is located at the center of the mounting frame.

[0008] Furthermore, the driving mechanism includes a first rotational driving member fixedly connected to the mounting frame, the output end of the first rotational driving member is fixedly connected to a driving shaft, a driving gear is fixedly sleeved on the outer surface of the driving shaft, and a first transmission gear ring is meshed with the outer surface of the driving gear and fixedly sleeved on the mounting ring.

[0009] Furthermore, the moving mechanism includes a second rotation drive component fixedly connected to the mounting bracket. The output end of the second rotation drive component is fixedly connected to a threaded rod rotatably connected to the mounting bracket. The outer surface of the threaded rod is threadedly connected to the transmission block. Two guide rods fixedly connected to the mounting bracket are slidably connected to the transmission block.

[0010] Furthermore, the clamping mechanism includes a clamping frame fixedly connected to the output end of the first telescopic drive member, and two second telescopic drive members are fixedly connected inside the clamping frame. The output ends of the two second telescopic drive members are all fixedly connected to clamping posts that are slidably connected to the clamping frame.

[0011] Furthermore, one of the clamping posts has a slot, and one end of the other clamping post is fixedly connected to a fixing post that is slidably connected to the slot. Clamping plates are fixedly connected to the outer surfaces of both clamping posts.

[0012] Furthermore, the transmission mechanism includes a third rotation drive component fixedly connected to the mounting frame, the output end of the third rotation drive component is fixedly connected to a transmission shaft, a transmission gear is fixedly sleeved on the outer surface of the transmission shaft, and a second transmission gear ring fixedly connected to the adjusting plate is meshed on the outer surface of the transmission gear.

[0013] Furthermore, an adjusting tank is fixedly connected to the placement compartment of one of the adjusting plates. The adjusting tank contains water of the same weight as the fire extinguishing bomb body. A drain pipe is fixedly connected to the bottom of the adjusting tank, and an electromagnetic flow control valve is installed on the drain pipe.

[0014] Furthermore, a water injection pipe is fixedly connected to the top of the regulating tank, and a sealing block is threadedly connected to the top end of the water injection pipe.

[0015] Compared with existing technologies, the high-altitude delivery drone for dry powder water-based fire extinguishing bombs provided by this invention has the following beneficial effects:

[0016] By incorporating multiple placement compartments on the mounting frame, and through the coordinated movement and clamping mechanisms, the drone can deploy multiple fire extinguishing bombs during a single flight. However, during bomb deployment, as the bombs move from front to back above the delivery pipe, the increased weight at the rear of the mounting frame can cause a shift in the center of gravity. Furthermore, the strong winds at high altitudes can significantly impact the drone's balance, potentially leading to loss of control and crashes. This drone addresses this issue by using a transmission mechanism to rotate adjusting plates, causing two plates to move forward from the mounting frame. This movement propels the fire extinguishing bombs within the placement compartments forward, effectively balancing the weight at the rear of the mounting frame and achieving equilibrium across the entire bomb-carrying area. This enhances the drone's stability during high-altitude bomb deployment, reduces the risk of crashes due to center of gravity shifts and wind effects, ensures the drone can safely and stably deploy multiple fire extinguishing bombs, and improves the reliability and success rate of firefighting operations.

[0017] An adjusting tank is installed in the placement compartment of one of the adjusting plates and filled with water of equal weight to the fire extinguishing bombs. A drain pipe and an electromagnetic flow control valve are also provided. After three fire extinguishing bombs are vertically deployed, as the horizontally positioned bombs move towards the deployment pipe, the weight increases on the side closer to the adjusting tank. At this point, the electromagnetic flow control valve is opened to control the drainage speed of the drain pipe, gradually draining the water from the adjusting tank, reducing the weight on the left side, and balancing the center of gravity of the mounting frame. This dynamic weight adjustment method cleverly solves the problem of center of gravity shift caused by bomb movement. While ensuring stable bomb deployment by the heavy-load drone, it can carry and deploy more fire extinguishing bombs, greatly improving the drone's fire extinguishing efficiency and enhancing its practicality in fire rescue and its ability to respond to large-scale fires.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1 to 5As shown, this invention provides a high-altitude delivery drone for dry powder water-based fire extinguishing bombs, including a heavy-load drone body 1. A mounting frame 2 is fixedly connected to the bottom of the heavy-load drone body 1. Multiple placement compartments 3 are provided inside the mounting frame 2. A mounting ring 4 is rotatably connected to the top of the mounting frame 2. A drive mechanism connected to the mounting frame 2 is transmittedly connected to the outer surface of the mounting ring 4, and the drive mechanism is used to drive the mounting ring 4 to rotate. A mounting bracket 5 is fixedly connected to the top of the mounting ring 4. A transmission block 6 is slidably connected to the mounting bracket 5. A moving mechanism connected to the mounting bracket 5 is provided on the transmission block 6, and the moving mechanism is used to drive the transmission block 6 to move horizontally. A first telescopic drive member 7 is fixedly connected to the bottom of the transmission block 6. The first telescopic drive member 7 is an electric telescopic rod or an electric hydraulic rod. A clamping mechanism is fixedly connected to the output end of the first telescopic drive member 7, and the clamping mechanism is used to clamp and fix the fire extinguishing bomb body.

[0029] Two adjusting plates 8 are rotatably connected inside the mounting frame 2. Each adjusting plate 8 is connected to a transmission mechanism that is connected to the mounting frame 2. Each adjusting plate 8 is fixedly connected to a placement bin 3. The transmission mechanism is used to drive the adjusting plate 8 to rotate. A feeding pipe 9 is set at the center of the mounting frame 2.

[0030] The drive mechanism includes a first rotation drive component 21 fixedly connected to the mounting frame 2. The first rotation drive component 21 is a servo motor. The servo motor is controlled by a PLC programming program, which can control the servo motor to rotate forward and backward and rotate at different angles. The output end of the first rotation drive component 21 is fixedly connected to a drive shaft 22. A drive gear 23 is fixedly sleeved on the outer surface of the drive shaft 22. A first transmission gear ring 24 fixedly sleeved on the outer surface of the drive gear 23 is meshed with the drive shaft 22. The first rotation drive component 21 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the first transmission gear ring 24 to rotate through the drive gear 23.

[0031] The moving mechanism includes a second rotation drive 31 fixedly connected to the mounting bracket 5. The second rotation drive 31 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the second rotation drive 31 is fixedly connected to a threaded rod 32 that is rotatably connected to the mounting bracket 5. The outer surface of the threaded rod 32 is threadedly connected to the transmission block 6. Two guide rods 33 that are fixedly connected to the mounting bracket 5 are slidably connected to the transmission block 6. The second rotation drive 31 drives the threaded rod 32 to rotate, and the threaded rod 32 drives the transmission block 6 to move horizontally on the guide rods 33.

[0032] The clamping mechanism includes a clamping frame 41 fixedly connected to the output end of the first telescopic drive member 7. Two second telescopic drive members 42 are fixedly connected inside the clamping frame 41. The second telescopic drive members 42 are electric telescopic rods or electric hydraulic rods. The output ends of the two second telescopic drive members 42 are fixedly connected to clamping posts 43 that are slidably connected to the clamping frame 41.

[0033] One of the clamping posts 43 has a slot 44, and one end of the other clamping post 43 is fixedly connected to a fixing post 45 that is slidably connected to the slot 44. The outer surfaces of both clamping posts 43 are fixedly connected to clamping plates 46. The clamping posts 43 are moved by the second telescopic drive member 42, so that the two clamping posts 43 are inserted into the fixing holes on the fire extinguishing bomb. At the same time, the fixing post 45 on the clamping post 43 is inserted into the slot 44, so that the clamping post 43 is stably fixed. At the same time, the clamping plate 46 on the clamping post 43 clamps and fixes, thus achieving stable clamping of the fire extinguishing bomb.

[0034] The transmission mechanism includes a third rotation drive component 51 fixedly connected to the mounting frame 2. The third rotation drive component 51 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. A transmission shaft 52 is fixedly connected to the output end of the third rotation drive component 51. A transmission gear 53 is fixedly sleeved on the outer surface of the transmission shaft 52. A second transmission gear ring 54 fixedly connected to the adjusting plate 8 is meshed on the outer surface of the transmission gear 53. The third rotation drive component 51 drives the transmission shaft 52 to rotate, and the transmission shaft 52 drives the second transmission gear ring 54 to rotate through the transmission gear 53.

[0035] First, place multiple dry powder or water-based fire extinguishing bombs of equal weight into the two vertical placement compartments 3 of the mounting frame 2 (see...). Figure 3 (As shown), a fire extinguishing bomb is also placed in the feeding pipe 9, and the second telescopic drive member 42 in the clamping frame 41 drives the clamping column 43 to move, so that the clamping column 43 fixes the fire extinguishing bomb, thus fixing the fire extinguishing bomb in the feeding pipe 9. Adjusting counterweights are placed in the two horizontal placement chambers 3 (see...). Figure 3As shown), the safety rope of each fire extinguishing bomb is fixedly connected to the bottom of the heavy-duty drone body 1. Then, the heavy-duty drone body 1 takes off, carrying multiple fire extinguishing bombs into the air. When the heavy-duty drone body 1 flies to the designated bombing position, the second telescopic drive member 42 drives the clamping column 43 to move, so that the clamping column 43 no longer clamps the fire extinguishing bomb. At this time, the fire extinguishing bomb moves downward under the action of gravity. At the same time, the safety rope is pulled, pulling out the safety rope on the fire extinguishing bomb, and the fire extinguishing bomb is activated. When the fire extinguishing bomb reaches the set height above the ground, it explodes to extinguish the fire. After the bombing is completed, when the next fire extinguishing bomb is to be dropped, the drive mechanism drives the mounting ring 4 and the mounting frame 5 to rotate 90°. Then, the moving mechanism drives the transmission block 6 to move, and the transmission block 6 drives the first telescopic drive member 7 to move, so that the first telescopic drive member 7 drives the clamping frame 41 to the position directly above the fire extinguishing bomb in front (see Figure 3 (As shown), then the first telescopic drive 7 drives the clamping frame 41 to move downwards, and the second telescopic drive 42 drives the clamping column 43 to move, so that the clamping column 43 clamps the top of the fire extinguishing bomb at a fixed position. Then the first telescopic drive 7 drives the clamping frame 41 to move upwards, so that the fire extinguishing bomb is removed from the placement chamber 3. Then, through the cooperation of the moving mechanism, the transmission block 6 is moved, thereby moving the removed fire extinguishing bomb towards the center position of the installation frame 2, so that it is moved above the feeding pipe 9. During the movement, because the fire extinguishing bomb is moved from front to back, the rear of the entire installation frame 2 is subjected to a large gravity, which is prone to center of gravity shift. Heavy-loaded drones encountering wind during high-altitude flight are prone to loss of balance and crash. To mitigate this, a transmission mechanism rotates the adjusting plates 8, causing the placement compartments 3 on the two adjusting plates 8 to rotate forward of the mounting frame 2. This moves the fire extinguishing bombs within the placement compartments 3 on the adjusting plates 8 forward, balancing the weight behind the mounting frame 2 and ensuring the entire weight distribution area of ​​the mounting frame 2 is balanced, allowing the heavy-loaded drone to maintain stable flight. Subsequently, fire extinguishing bombs are dispensed from the feeding pipe 9. When dispensing fire extinguishing bombs from behind the mounting frame 2, these bombs need to be moved into the feeding pipe 9 (see [reference]). Figure 3 As shown in the figure, at this time, the transmission mechanism drives the adjustment plate 8 to move backward to achieve dynamic balance, thereby enabling the UAV to stably drop multiple fire extinguishing bombs at one time.

[0036] Example 2

[0037] Based on Example 1, please refer to Figures 2 to 5As shown, an adjusting tank 61 is fixedly connected to the placement compartment 3 on one of the adjusting plates 8. The adjusting tank 61 contains water of the same weight as the main body of the fire extinguishing bomb. A drain pipe 62 is fixedly connected to the bottom of the adjusting tank 61. An electromagnetic flow control valve 63 is installed on the drain pipe 62.

[0038] A water injection pipe is fixedly connected to the top of the regulating tank 61, and a sealing block is threadedly connected to the top of the water injection pipe.

[0039] An equal weight of dry powder or water-based fire extinguishing bombs is placed in the placement chamber 3 on one of the adjusting plates 8, and an equal weight of water is injected into the adjusting tank 61. After the three fire extinguishing bombs in the vertical direction are fed, the first telescopic drive 7 is moved by the moving mechanism, causing the clamping frame 41 to move above the horizontally positioned fire extinguishing bombs. The fire extinguishing bombs are then removed from the placement chamber 3 and moved towards the feeding pipe 9. During this movement, the weight on the side closest to the adjusting tank 61 increases. When the fire extinguishing bombs begin to move, the electromagnetic flow control valve 63 on the drain pipe 62 is opened. The electromagnetic flow control valve 63 controls the drainage speed of the drain pipe 62, gradually draining the water from the adjusting tank 61, thereby reducing the weight on the left side (see...). Figure 3 As shown in the figure, this balances the center of gravity of the mounting frame 2, and then the fire extinguishing bomb is released, thereby further increasing the number of bombs dropped by the drone in one flight while maintaining stable bomb dropping by the heavy-load drone.

[0040] Working principle:

[0041] Preparation:

[0042] Fire extinguishing bombs and counterweight placement: Place multiple dry powder or water-based fire extinguishing bombs of equal weight into the two vertical placement chambers 3 of the mounting frame 2, and also place one fire extinguishing bomb into the feeding pipe 9. The second telescopic drive 42 within the clamping frame 41 moves the clamping column 43 to secure the fire extinguishing bomb. Adjustable counterweights are placed in the two horizontal placement chambers 3, and the safety rope for each fire extinguishing bomb is securely connected to the bottom of the heavy-duty drone body 1.

[0043] Preparation of the regulating tank: Fix the regulating tank 61 in the placement compartment 3 on one of the regulating plates 8, inject water of the same weight as the fire extinguishing bomb body into the regulating tank 61 through the water injection pipe, and then seal the top of the water injection pipe with a sealing block.

[0044] Takeoff and first bomb drop: The main body 1 of the heavy-duty UAV takes off, carrying multiple fire extinguishing bombs into the air. After flying to the designated bomb drop position, the second telescopic drive component 42 drives the clamping column 43 to move, dropping the fire extinguishing bomb in the middle position of the mounting frame 2 to extinguish the fire.

[0045] Subsequent bombing process:

[0046] Rotation and Movement Preparation: After the first bomb is dropped, the drive mechanism is activated when the next fire extinguishing bomb is dropped. The first rotation drive component 21 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the first transmission gear ring 24 to rotate through the drive gear 23, which in turn drives the mounting ring 4 and the mounting bracket 5 to rotate 90°.

[0047] Clamping the fire extinguishing bomb: The moving mechanism operates, with the second rotary drive 31 driving the threaded rod 32 to rotate. The threaded rod 32 drives the transmission block 6 to move horizontally on the guide rod 33. The transmission block 6 drives the first telescopic drive 7 to move, causing the first telescopic drive 7 to move the clamping frame 41 to a position directly above the fire extinguishing bomb. The first telescopic drive 7 then drives the clamping frame 41 downwards, and the second telescopic drive 42 drives the clamping column 43 to move, clamping the column 43 at a fixed position on the top of the fire extinguishing bomb.

[0048] Remove the fire extinguishing bomb: The first telescopic drive 7 drives the clamping frame 41 to move upward, so that the fire extinguishing bomb is removed from the placement chamber 3.

[0049] Balance Adjustment (First Time): The moving mechanism, in conjunction with the transmission block 6, moves the displaced fire extinguishing bomb towards the center of the mounting frame 2, above the feeding pipe 9. During this movement, the weight behind the mounting frame 2 is relatively large, making it prone to center of gravity shift, and the wind can easily cause the drone to lose balance and control. At this time, the transmission mechanism works, and the third rotation drive component 51 drives the transmission shaft 52 to rotate. The transmission shaft 52 drives the second transmission gear ring 54 to rotate through the transmission gear 53, causing the two adjusting plates 8 to rotate forward of the mounting frame 2, moving the fire extinguishing bomb in the placement compartment 3 forward, balancing the weight behind the mounting frame 2, and maintaining stable flight of the drone.

[0050] Feeding: The fire extinguishing bombs located in the feeding pipe 9 are fed.

[0051] Balance adjustment (second time): When the fire extinguishing bomb behind the installation frame 2 is deployed, it needs to be moved into the feeding pipe 9. At this time, the transmission mechanism drives the adjusting plate 8 to move backward to achieve dynamic balance.

[0052] An equal weight of dry powder or water-based fire extinguishing bombs is placed in the placement compartment 3 on one of the adjustment plates 8, and an equal weight of water is injected into the adjustment tank 61. After the three fire extinguishing bombs in the vertical direction are added, the moving mechanism drives the first telescopic drive component 7 to move, causing the clamping frame 41 to move above the fire extinguishing bomb in the horizontal position, removing the fire extinguishing bomb from the placement compartment 3 and moving it to the feeding pipe 9. During the movement, the weight on the side closer to the adjustment tank 61 increases, opening the electromagnetic flow control valve 63 on the drain pipe 62 to control the drainage speed of the drain pipe 62, allowing the water in the adjustment tank 61 to gradually drain out, reducing the weight on the left side, balancing the center of gravity of the mounting frame 2, and releasing the fire extinguishing bomb. This increases the number of bombs dropped by the drone in a single flight while maintaining stable bomb dropping by the heavy-load drone.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
