Description

Technical Field

[0001] This utility model relates to the field of electronic fireworks technology, and in particular to an aerial electronic fireworks spraying device based on a drone. Background Technology

[0002] In celebrations, festivals, and large-scale events, electronic fireworks are gradually replacing traditional gunpowder fireworks due to their advantages of being gunpowder-free, pollution-free, and low-risk. They simulate the effect of fireworks by using gas combustion and light rendering, which not only retains the visual appeal of fireworks but also avoids the safety and environmental problems of traditional fireworks. They have become the core equipment for creating atmosphere in various events, and the demand for electronic fireworks is even more urgent in scenarios that require aerial display effects. However, traditional electronic fireworks are mostly fixed installation structures, with the barrel angle and spray direction preset before leaving the factory. They cannot be adjusted in real time according to actual needs during the firing process. If the bloom pattern needs to be changed, it needs to be manually disassembled and reassembled, which is cumbersome and time-consuming, making it difficult to adapt to dynamically changing event scenarios. Utility Model Content

[0003] In response to the technical problem that most electronic fireworks are fixed installation structures with preset barrel angles and spray directions at the factory, making it impossible to adjust them in real time according to actual needs during the firing process, this utility model provides an aerial electronic fireworks spraying device based on a drone.

[0004] The technical solution adopted by this utility model is: an aerial electronic fireworks spraying device based on a drone, including a mounting plate, in which multiple sets of cannons are rotatably connected, and multiple sets of rotating rods are rotatably connected, one end of each rotating rod being fixedly connected to a cannon. A launching assembly is provided on the outside of the mounting plate, and an adjustment assembly for adjusting the angle of the cannons is also provided on the outside of the mounting plate.

The outer side of the rotating rod is fixedly connected with a first gear, the outer side of the gear is provided with a rack, the bottom of the rack is fixedly connected with a sliding rod, and the connecting rod is fixedly connected to the sliding rod.

[0009] In one embodiment, the third fixing rod is externally fixedly connected to a fixing frame, and the sliding rod passes through the fixing frame.

[0010] In one embodiment, the adjusting assembly includes a motor and a threaded cylinder.

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] To address the problems existing in the background technology, this application proposes the following technical solution: an aerial electronic fireworks spraying device based on a drone, including a mounting plate 1, a plurality of cannons 8 rotatably connected in the mounting plate 1, a plurality of rotating rods 9 rotatably connected in the mounting plate 1, one end of the rotating rods 9 being fixedly connected to the cannons 8, a launching assembly being provided on the outside of the mounting plate 1, and an adjustment assembly for adjusting the angle of the cannons 8 being provided on the outside of the mounting plate 1.

[0019] In this embodiment, the mounting plate 1 provides a stable mounting platform for the cannon barrel 8, rotating rod 9, launching assembly, and adjustment assembly. Its flat structure ensures accurate installation of each component, avoiding deviations in the fireworks spray caused by installation misalignment. Multiple sets of cannon barrels 8 are rotatably connected to the mounting plate 1, enabling multi-angle spraying and breaking the limitation of traditional ground fireworks spraying in a single direction, creating a more three-dimensional and richer visual effect in the air. Each set of cannon barrels 8 corresponds to a set of rotating rods 9, which are fixedly connected to the cannon barrels 8. This allows the power of the adjustment assembly to be accurately transmitted to the cannon barrels 8, causing the cannon barrels 8 to rotate around the mounting plate 1, thereby adjusting the spray angle.

[0020] In this embodiment, a first fixing rod 2 is fixedly connected to the top of the mounting plate 1, a mounting bracket 3 is fixedly connected to the top of the first fixing rod 2, a second fixing rod 4 is fixedly connected to the bottom of the mounting plate 1, a support ring 7 for support is fixedly connected to the bottom of the second fixing rod 4, and a third fixing rod 5 is fixedly connected to the bottom of the second fixing rod 4. The firing assembly includes an oxygen storage tank 19 and a combustible gas storage tank 22 fixedly connected to the outside of the first fixing rod 2. An igniter is fixedly connected inside the gun barrel 8. Multiple sets of first delivery pipes 20 are fixedly connected to the oxygen storage tank 19. A first solenoid valve 21 is fixedly connected to the first delivery pipe 20. The first delivery pipe 20 is fixed to the gun barrel 8. The combustible gas storage tank 22 is fixedly connected to multiple sets of second delivery pipes, each containing a second solenoid valve 23. These second delivery pipes are also fixedly connected to the cannon barrel 8. A first fixing rod 2 is vertically fixed to the top of the mounting plate 1, providing stable support for both the oxygen storage tank 19 and the combustible gas storage tank 22, and maintaining a certain distance between the storage tanks and the mounting plate 1 to prevent them from being affected by the high temperature of the cannon barrel 8. The top mounting bracket 3 is used to connect to the UAV fuselage; its structural design is compatible with the mounting interfaces of most UAVs, allowing for installation without significant modifications to the UAV, thus improving the device's versatility and adaptability. The second fixing rod 4 and the third fixing rod 5 work together to form a stable support structure at the bottom of the mounting plate 1, which can be used to install related components of the adjustment assembly, while also balancing the weight on both sides of the mounting plate 1 to prevent instability in UAV flight due to a shift in the center of gravity.

[0021] In this embodiment, the oxygen storage tank 19 and the combustible gas storage tank 22 in the launching assembly store the oxidizer and fuel, respectively. Both are supplied to the cannon barrel 8 via independent delivery pipes (first delivery pipe 20 and second delivery pipe), ensuring that the fuel and oxidizer are mixed in proportion, improving combustion efficiency, and making the fireworks spray more powerfully and bloom more fully. The first solenoid valve 21 and the second solenoid valve 23 control the on / off state and flow rate of the two gas lines, respectively. These can be precisely adjusted via remote control or a preset program to avoid gas waste and prevent incomplete combustion or weak spray due to improper gas mixing ratios. For example, when a weaker spray effect is needed, the opening of the solenoid valve can be reduced to decrease the gas supply; when a strong bloom effect is needed, the opening can be increased to ensure a sufficient gas supply. The igniter inside the cannon barrel 8 is in direct contact with the mixed gas and can ignite immediately after the gas is delivered, avoiding gas leakage caused by ignition delay and improving the timeliness and safety of the spray. Especially in the air environment, precise ignition can prevent the spread of unignited gas and the resulting safety hazards. Specific control can be achieved through a control module, which is existing technology.

[0022] In this embodiment, the outer side of the second fixing rod 4 is fitted with a threaded sleeve 15, the outer side of the threaded sleeve 15 is provided with external threads, and multiple sets of connecting rods 16 are fixedly connected to the outer side of the threaded sleeve 15. The outer side of the rotating rod 9 is fixedly connected with a first gear 10, the outer side of the gear is provided with a rack 11, the bottom of the rack 11 is fixedly connected with a slide rod 12, the connecting rod 16 is fixedly connected with the slide rod 12, the outer side of the third fixing rod 5 is fixedly connected with a fixing frame 6, the slide rod 12 passes through the fixing frame 6, the adjusting assembly includes a motor 17 and a threaded cylinder 13, the threaded cylinder 13 is rotatably connected to the bottom of the mounting plate 1, the threaded cylinder 13 is fitted outside the threaded sleeve 15 and threadedly connected to it, the motor 17 is fixedly connected to the bottom of the mounting plate 1, the output end of the motor 17 is fixedly connected with a second gear 18, the outer side of the threaded cylinder 13 is fixedly connected with a gear ring 14, the second gear 18 meshes with the gear ring 14, and the outer side of the second fixing rod 4 is fitted with a spring, the two ends of the spring abut against the fixing frame 6 and the threaded sleeve 15 respectively. The threaded sleeve 15 on the outside of the second fixed rod 4 can slide along the axial direction of the rod. Its external thread cooperates with the threaded cylinder 13, converting the rotational motion of the threaded cylinder 13 into the linear motion of the threaded sleeve 15. This transmission method has the advantages of precise transmission and good self-locking, which can ensure that the threaded sleeve 15 stays stably after being adjusted to the position, and avoid the threaded sleeve 15 sliding on its own due to the vibration of the UAV, thereby ensuring the stability of the angle of the gun barrel 8. Multiple sets of connecting rods 16 fix the threaded sleeve 15 to the slide rod 12, so that the linear movement of the threaded sleeve 15 can synchronously drive the slide rod 12 to move. The slide rod 12 passes through the fixing frame 6, and the fixing frame 6 provides a guiding function for the slide rod 12, ensuring that the slide rod 12 always moves in a straight line and avoiding the slide rod 12 from deviating and causing the rack 11 and the first gear 10 to mesh and misalign. The meshing transmission between the rack 11 and the first gear 10 can convert the linear movement of the slide rod 12 into the rotational movement of the rotating rod 9, thereby driving the barrel 8 to rotate and realize angle adjustment. Compared with the traditional linkage transmission, the gear rack 11 transmission is more stable and the angle adjustment accuracy is higher. It can realize the precise control of the small angle of the barrel 8, making the fireworks display pattern more delicate.

[0023] In this embodiment, in the adjustment assembly, the motor 17 serves as the power source, driving the threaded cylinder 13 to rotate through the meshing of the second gear 18 and the gear ring 14. The gear meshing transmission is highly efficient and low-noise, suitable for the silent operation requirements of UAVs in the air, avoiding environmental impact due to transmission noise. The motor 17's rotational speed can be adjusted remotely, thereby controlling the rotational speed of the threaded cylinder 13, achieving flexible control of the barrel 8 angle adjustment speed—for example, when rapid angle adjustment is needed to form a dynamic pattern, the motor 17's rotational speed can be increased; when fine angle adjustment is needed, the rotational speed can be decreased to ensure precise adjustment. The two ends of the spring on the outside of the second fixing rod 4 abut against the fixing frame 6 and the threaded sleeve 15 respectively. When the threaded sleeve 15 slides upward, it can compress the spring. When the threaded sleeve 15 slides downward, it can use the spring force to assist in resetting, avoiding jamming caused by the thread fit clearance of the threaded sleeve 15, ensuring a smooth adjustment process. At the same time, the spring force can offset part of the weight of the threaded sleeve 15, reduce the load on the motor 17, and extend the service life of the motor 17. Especially when the UAV is flying at an angle, the spring can prevent the threaded sleeve 15 from shifting due to gravity, ensuring the stable operation of the adjustment component.

[0024] The usage method of this embodiment is as follows: First, securely connect the device to the drone fuselage via mounting bracket 3, ensuring a firm installation. Check that the medium levels in the oxygen storage tank 19 and the combustible gas storage tank 22 are sufficient. Check that the connections of each delivery pipe (first delivery pipe 20, second delivery pipe) are tight and leak-free. Confirm that the first solenoid valve 21 and the second solenoid valve 23 are closed, and that the angle of the cannon barrel 8 is in its initial position. Start the drone and control it to fly to the preset fireworks display area. Activate the adjustment component via the remote controller: control motor 17 to operate, the output of motor 17 drives the second gear 18 to rotate, the second gear 18 meshes with the gear ring 14 to drive the threaded cylinder 13 to rotate, the threaded cylinder 13 and the threaded sleeve 15 are threadedly engaged, causing the threaded sleeve 15 to slide axially along the second fixed rod 4, the threaded sleeve 15 drives the slide rod 12 to move linearly along the fixed bracket 6 via the connecting rod 16, the slide rod 12 drives the rack 11 to move, the rack 11 meshes with the first gear 10 to rotate the rotating rod 9, the rotating rod 9 drives the cannon barrel 8 to rotate around the mounting plate 1 to the preset spray angle, and then turn off motor 17. The launch assembly is then activated: The first solenoid valve 21 and the second solenoid valve 23 are remotely opened. Oxygen from the oxygen storage tank 19 is delivered to the cannon barrel 8 via the first delivery pipe 20 and combustible gas from the combustible gas storage tank 22 via the second delivery pipe, according to a preset ratio. Once the gases are properly mixed, the igniter in the cannon barrel 8 is ignited. The thrust generated by the combustion of the mixed gas propels the fireworks material out of the cannon barrel 8, creating a bursting effect in the air. If the fireworks pattern needs adjustment, the adjustment assembly can be activated again to change the angle of the cannon barrel 8, repeating the launch steps. After the fireworks are launched, the first solenoid valve 21 and the second solenoid valve 23 are closed, and the drone is controlled to return to base. After a stable landing, the device is disassembled, and all components are checked for integrity. The oxygen storage tank 19 and the combustible gas storage tank 22 are replenished or maintained for future use.
