Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a multi-rotor drone fire extinguishing bomb tilting and dropping device. Background Technology

[0002] The purpose of a multi-rotor drone fire extinguishing bomb tilting delivery device is to utilize the advantages of drones to achieve rapid response to fires, accurate delivery of fire extinguishing bombs, improved fire extinguishing efficiency, reduced personnel risks, and flexible adaptation to complex environments.

[0003] While existing technologies offer many advantages, current multi-rotor drone fire extinguishing bomb tilting devices require adjustment of the tilt angle before takeoff. Since some drones can carry multiple fire extinguishing bombs at once, and airborne personnel cannot continuously adjust the deployment angle, multiple bombs are dropped on the same fire point, reducing the drone's firefighting efficiency, causing the fire to escalate, and increasing the fire's impact on the surrounding environment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-rotor UAV fire extinguishing bomb tilting and launching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-rotor UAV fire extinguishing bomb tilting and launching device, comprising: a mounting body, which is fixedly mounted on the bottom of the multi-rotor UAV by bolts; two U-shaped plates are fixedly mounted on the outer surface of the mounting body; stepper motors are fixedly mounted on the outer surfaces of the two U-shaped plates; rotating shafts are fixedly mounted on the opposite outer surfaces of the two stepper motors via output shafts; fire extinguishing bomb launching devices are fixedly mounted on the opposite outer surfaces of the two rotating shafts; gears are fixedly mounted on the outer surfaces of the two rotating shafts; two toothed plates are meshed with the two gears in the vertical direction; dampers are fixedly mounted at the four corners of the toothed plates; permanent magnets are fixedly mounted on the outer surfaces of the toothed plates; a working groove is formed on the side of the mounting body near the toothed plates; an electromagnet is fixedly mounted inside the working groove, which reduces the angle change of the fire extinguishing bomb launching device to a certain extent when launching the fire extinguishing bomb, and improves the launching accuracy to a certain extent.

[0006] In a preferred embodiment, two transmission plates are provided in the horizontal direction of each of the two gears. A rotating shaft is fixedly installed on the side of each of the transmission plates near the two gears. Two springs are fixedly installed on the outer surface of each of the rotating shafts. A fixing rod is fixedly connected to the end of each of the springs away from the rotating shafts. A working groove is provided on the side of the mounting body near the transmission plates. A push-type light controller is fixedly installed inside the working grooves. Multiple signal lights are fixedly installed at the bottom of the mounting body, which further improves the deployment accuracy of the fire extinguishing bomb dispensing device and further improves the fire extinguishing efficiency.

[0007] In a preferred embodiment, when the multiple electromagnets are energized, they can generate magnetic force on the multiple permanent magnets, causing the multiple permanent magnets to drive the multiple gear plates to move, so that the gear plates no longer limit the gears.

[0008] In a preferred embodiment, the two rotating shafts are movably embedded in the inner surface of the mounting body, and the multiple dampers, permanent magnets and toothed plates are movably embedded in the interior of the multiple working slots. The rotating shafts can rotate under the drive of the stepper motor output shaft.

[0009] In a preferred embodiment, the two gears are movably embedded in the inner surface of the mounting body. The cooperation between the gears and the toothed plate can, to a certain extent, prevent the angle of the fire extinguishing bomb dispensing device from changing during bomb dispensing.

[0010] In a preferred embodiment, both gears can simultaneously actuate multiple transmission plates when rotating. In a horizontal state, multiple transmission plates can press multiple push-type light controllers to illuminate multiple indicator lights. Each flash of an indicator light indicates that the gear has rotated by one tooth, which is the angle by which the rotating shaft drives the fire extinguishing bomb dispensing device to rotate.

[0011] In a preferred embodiment, multiple rotating shafts are movably embedded in the inner surface of the mounting body, multiple transmission plates and springs are movably embedded in the interior of multiple working slots, and multiple fixing rods are fixedly connected to the vertical inner wall of multiple working slots. The springs can provide power for the reverse rotation of the rotating shafts.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention utilizes a stepper motor to drive the rotation of a rotating shaft via its output shaft, allowing for online adjustment of the angle of the fire extinguishing grenade launching device. Then, through the cooperation of a damper, electromagnet, permanent magnet, gear plate, and gears, the rotating shaft achieves self-locking. This reduces the angle changes of the fire extinguishing grenade launching device during launch, improves launching accuracy, enhances fire extinguishing efficiency, and reduces the impact of fires on the surrounding environment.

[0014] This invention utilizes a gear to drive a transmission plate, causing a flashing signal light. Each flash of the signal light represents the angle of one tooth rotation of the gear. Therefore, the angle of rotation of the fire extinguishing bomb throwing device in the air can be indirectly calculated by the number of flashes of the signal light, thereby improving the throwing accuracy of the fire extinguishing bomb throwing device, further improving the fire extinguishing efficiency, and further reducing the impact of fire on the surrounding environment.

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

[0022] Please see Figure 1-4 This utility model provides a technical solution: a tilting and launching device for fire extinguishing projectiles from a multi-rotor drone, comprising: a mounting body 1, which is fixedly mounted on the bottom of the multi-rotor drone by bolts; two U-shaped plates 2 are fixedly mounted on the outer surface of the mounting body 1; stepper motors 3 are fixedly mounted on the outer surface of each of the two U-shaped plates 2; rotating shafts 4 are fixedly mounted on the opposite outer surfaces of the two stepper motors 3 via output shafts; fire extinguishing projectile launching devices 5 are fixedly mounted on the opposite outer surfaces of the two rotating shafts 4; gears 7 are fixedly mounted on the outer surfaces of the two rotating shafts 4; two toothed plates 8 are meshed vertically on the two gears 7; dampers 9 are fixedly mounted at the four corners of the toothed plates 8; permanent magnets 10 are fixedly mounted on the outer surfaces of the toothed plates 8; and a working groove 6 is provided on the side of the mounting body 1 near the toothed plates 8. An electromagnet 11 is fixedly mounted inside the working groove 6. This reduces the angle change of the fire extinguishing projectile launching device 5 when launching fire extinguishing projectiles, improves the launching accuracy, increases the fire extinguishing efficiency, and reduces the impact of fire on the surrounding environment.

[0023] like Figure 1-4 As shown, two transmission plates 15 are provided in the horizontal direction of each of the two gears 7. A rotating shaft 12 is fixedly installed on the side of the multiple transmission plates 15 near the two gears 7. Two springs 13 are fixedly installed on the outer surface of the multiple rotating shafts 12. A fixing rod 14 is fixedly connected to the end of the multiple springs 13 away from the multiple rotating shafts 12. A working groove 17 is opened on the side of the mounting body 1 near the multiple transmission plates 15. A push-type light controller 16 is fixedly installed inside the multiple working grooves 17. Multiple signal lights 18 are fixedly installed at the bottom of the mounting body 1. This further improves the release accuracy of the fire extinguishing bomb release device 5, further improves the fire extinguishing efficiency, and further reduces the impact of the fire on the surrounding environment.

[0024] like Figure 1-4 As shown, when multiple electromagnets 11 are energized, they can generate magnetic force on multiple permanent magnets 10, causing multiple permanent magnets 10 to drive multiple toothed plates 8 to move. Consequently, the toothed plates 8 no longer limit the gear 7, and at this time, the rotating shaft 4 can drive the fire extinguishing bomb dispensing device 5 to rotate.

[0025] like Figure 1-4As shown, two rotating shafts 4 are movably embedded in the inner surface of the mounting body 1. Multiple dampers 9, permanent magnets 10 and toothed plates 8 are movably embedded in the interior of multiple working slots 6. The rotating shafts 4 can rotate under the drive of the output shaft of the stepper motor 3 to change the tilt angle of the fire extinguishing bomb dispensing device 5.

[0026] like Figure 1-4 As shown, two gears 7 are movably embedded in the inner surface of the mounting body 1. The cooperation between the gears 7 and the toothed plate 8 can, to a certain extent, prevent the angle of the fire extinguishing bomb dispensing device 5 from changing during bomb dispensing and improve the bomb dispensing accuracy to a certain extent.

[0027] like Figure 1-4 As shown, when the two gears 7 rotate, they can simultaneously actuate multiple transmission plates 15. When the multiple transmission plates 15 are in a horizontal state, they can press multiple push-type light controllers 16, causing multiple signal lights 18 to light up. Each flash of a signal light 18 indicates that the gear 7 has rotated by one tooth, which is the angle by which the rotating shaft 4 drives the fire extinguishing bomb dispensing device 5 to rotate. This allows the calculation of how many degrees the fire extinguishing bomb dispensing device 5 has rotated, thus improving the bomb dispensing accuracy to a certain extent.

[0028] like Figure 1-4 As shown, multiple rotating shafts 12 are movably embedded in the inner surface of the mounting body 1, multiple transmission plates 15 and springs 13 are movably embedded in the interior of multiple working slots 17, and multiple fixing rods 14 are fixedly connected to the vertical inner wall of the multiple working slots 17. The springs 13 can provide power for the reverse rotation of the rotating shafts 12, causing the rotating shafts 12 to rotate in the opposite direction.

[0029] Working Principle: This device can be bolted to the bottom of a multi-rotor drone to achieve the tilting and dropping function of fire extinguishing bombs. In use, the drone, driven by a remote control, propels the mounting body 1 to the fire extinguishing bomb dropping area. Then, the electromagnet 11 in the working slot 6 is activated. The electromagnet 11 generates magnetic force, causing the permanent magnet 10 to move the gear plate 8. The movement of the gear plate 8 compresses the damper 9, giving it elastic potential energy. At this point, the gear plate 8 no longer jams the gear 7, allowing the gear 7 to rotate with the rotating shaft 4. Start the stepper motor 3 on the U-shaped plate 2. The stepper motor 3 drives the rotating shaft 4 to rotate through the output shaft. The rotating shaft 4 drives the fire extinguishing bomb dispensing device 5 and the gear 7 to rotate synchronously. When the gear 7 rotates, each tooth will slightly push the transmission plate 15 in the working groove 17, causing the transmission plate 15 to drive the rotating shaft 12 to rotate around the axis of the rotating shaft 12. The rotating shaft 12 causes the spring 13 on the fixed rod 14 to deform. At this time, the spring 13 has elastic potential energy. And because the rotating shaft 12 is close to the teeth The gear 7 is mounted on one side, and the shaft 12 divides the transmission plate 15 into a driving part and a driven part. The side closer to the gear 7 is the driving part. Utilizing the lever principle, when the driving side rotates slightly, the driven side rotates significantly. At this time, the transmission plate 15 no longer presses the push-type light controller 16, and the signal light 18 goes out. When the teeth of the gear 7 no longer move the transmission plate 15, the spring 13 releases its elastic potential energy, causing the transmission plate 15 to rotate in the opposite direction and become parallel, pressing the push-type light controller 16 and causing the signal light 18 to light up again, resulting in the flashing of the signal light 18. When the angle of the fire extinguishing bomb launching device 5 meets the requirements, the stepper motor 3 stops, and then the electromagnet 11 stops. At this time, the electromagnet 11 no longer generates magnetic force, and the damper 9 releases its elastic potential energy, causing the toothed plate 8 to lock onto the gear 7 again, restricting the rotation of the gear 7, and thus restricting the rotation of the shaft 4. This reduces the change in the angle of the fire extinguishing bomb launching device 5 when launching fire extinguishing bombs, and improves the launching accuracy to a certain extent.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
