Description

Technical Field

[0001] This invention relates to the field of fireworks technology, specifically to a fireworks launch tube and a drone fireworks launching system. Background Technology

[0002] In the field of fireworks displays, single-shot effect tubes are the core components for creating specific fireworks effects. Their basic structure typically includes propellant and effect powder, with an ignition wire at the rear of the tube. During actual firing, an electronic ignition wire receives a control signal, and the igniter head, under the excitation of an electric current, ignites the propellant, launching the effect powder into the air and igniting it, ultimately forming the desired fireworks pattern.

[0003] However, these types of fireworks tubes generate significant recoil upon launch, typically limiting their use to ground-based mounting. For aerial launch scenarios (such as those mounted on drone platforms or high-altitude launch towers), the industry standard is to pre-design paired mounting tubes on a combined launcher. Two fireworks tubes are inserted into their respective mounting tubes with their launch ports facing away from each other, forming a counter-firing structure. Upon ignition, the pair of fireworks tubes are launched synchronously, using their opposing recoil forces to cancel each other out. While this counter-firing method solves the stability problem of aerial launches, it requires paired launches, making it impossible to achieve independent fireworks effects on only one side or to present different fireworks effects on opposite sides.

[0004] Patent document CN117804283A discloses a suspended fireworks display tower, which installs multiple fireworks display brackets on a fixed ring in the circumferential direction. It achieves recoil cancellation by forcing pairs of fireworks to be launched. This fireworks display device cannot achieve independent effect display on one side. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fireworks launch tube and a drone fireworks launch system.

[0006] The fireworks launch tube provided by the present invention includes an outer tube, a blank tube, and an effect tube, wherein the blank tube contains propellant and the effect tube contains propellant and effect powder.

[0007] The empty cannon and the effect tube are coaxially installed inside the outer tube, with the firing end of the empty cannon facing the empty cannon firing end of the outer tube, and the firing end of the effect tube facing the fireworks firing end of the outer tube.

[0008] Preferably, a damping block is provided inside the outer tube, and the damping block is disposed between the empty barrel and the effect barrel.

[0009] Preferably, an extension tube is coaxially mounted on the fireworks launching end of the outer tube.

[0010] Preferably, a diffuser is coaxially mounted on the air-launching end of the outer tube.

[0011] Preferably, the outer tube has a wire outlet slit on its side, and the electronic ignition wires at the tail end of the empty gun barrel and the tail end of the effect tube both extend to the outside of the outer tube through the wire outlet slit.

[0012] Preferably, one end of the extension tube is fixedly installed inside the outer tube, and the other end of the extension tube extends coaxially toward the outside of the outer tube to form an extended firing end. The effect tube is emitted from the extended firing end after being ignited.

[0013] Preferably, the diffuser has a trumpet-shaped structure.

[0014] The unmanned aerial vehicle (UAV) fireworks launching system provided by the present invention includes a UAV, a mounting frame, and the aforementioned fireworks counter-firing launch tube;

[0015] The fireworks launch tubes are installed horizontally or at an angle in the mounting frame, and the fireworks launch end and the air cannon launch end of the outer tube extend to the outside of the two sides of the mounting frame, respectively. The mounting frame is installed on the top or bottom of the UAV.

[0016] Preferably, there are multiple firework launch tubes, and the firework launch ends of the outer tubes of the multiple firework launch tubes all face the same side of the mounting frame to form a preset firework effect.

[0017] Preferably, there are multiple firework launch tubes, and in some of the multiple firework launch tubes, the firework launch end of the outer tube faces the side of the mounting frame to form a first preset firework effect;

[0018] In another part of the fireworks launch tube, the outer tube's fireworks launch end faces the opposite side of the mounting frame, used to create a second preset fireworks effect. Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention has a simple structure. By placing the effect tube and the empty cannon tube into an outer tube to form a single-shot firework tube without recoil, it solves the problem that the existing opposing firework launch structure requires pairing for launch. Since there is no effect interference from the other end, the effect surface can be freely shaped into a single side.

[0020] 2. This invention integrates a firework tube with a counter-firing function into an outer tube, forming a constraint on the counter-firing direction. During installation, there is no need to adjust the position of the mounting tube on the launcher. The launch tube of this invention can be installed simply by passing it through the mounting frame, making the installation more convenient and flexible. Attached Figure Description

[0036] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0037] This invention discloses a firework launch tube and a drone firework launch system. By placing the counter-firing structure formed by the effect tube and the empty cannon tube into an outer tube, a single-shot firework tube without recoil is formed. This not only solves the problem of the existing counter-firing firework launch structure requiring paired launch, but also allows for free single-sided shaping of the effect surface due to the absence of effect interference from the other end. Furthermore, the outer tube can constrain the counter-firing direction. During installation, there is no need to adjust the position of the paired mounting tubes on the launch frame; the launch tubes only need to be passed through the mounting frame for installation, making the installation more convenient and flexible.

[0038] The firework launch tube provided by the present invention, such as Figures 3-6 As shown, the device includes an outer tube 1, an empty cannon 4, and an effect tube 3. The empty cannon 4 contains propellant 9, and the effect tube 3 contains propellant 9 and effect powder 10. The empty cannon 4 and the effect tube 3 are coaxially installed inside the outer tube 1, with the firing end of the empty cannon 4 facing the empty cannon firing end of the outer tube 1, and the firing end of the effect tube 3 facing the firework firing end of the outer tube 1. When the firework is launched, the propellant 9 inside the effect tube 3 and the empty cannon 4 are ignited simultaneously, generating coaxial and opposite forces to cancel out the recoil. Since the empty cannon 4 does not contain effect powder 10, there is no need to force the firework to launch, and a unilateral firework effect can be achieved.

[0039] In a preferred embodiment, a damping block 7 is provided inside the outer tube 1. The damping block 7 is disposed between the empty barrel 4 and the effect barrel 3. The damping block 7 is made of a material with high elasticity and high damping coefficient. Its outer diameter matches the inner diameter of the cylindrical outer tube 1. It is securely installed through an interference fit. The two end faces of the damping block 7 are in direct contact with the tail of the empty barrel 4 and the tail of the effect barrel 3, respectively. By coaxially installing the empty barrel 4 and the effect barrel 3 inside the outer tube 1 and tightly embedding the damping block 7 between them, the slight difference between the recoil force generated by the empty barrel 4 and the effect barrel 3 can be completely absorbed and eliminated. Furthermore, it can prevent the recoil force from being transmitted to the mounting frame 11, significantly reducing the structural load of the mounting frame 11.

[0040] In a preferred embodiment, to optimize the fireworks effect (such as increasing the range or enhancing the concentration of starburst), an extension tube 5 can be coaxially installed at the fireworks launch end of the outer tube 1. One end of the extension tube 5 is fixedly installed inside the outer tube 1, and the other end of the extension tube 5 extends coaxially towards the outside of the outer tube 1, forming an extended launch end. The effect tube 3 is launched from the extended launch end after being ignited. The extension tube 5 can be fixed to the fireworks launch end of the outer tube 1 by means of threads, snap-fit, or welding, and its length can be adjusted according to the effect requirements. However, the addition of the extension tube 5 will further increase the recoil after launch, disrupting the original counterbalance with the empty cannon tube 4. To address this problem, the present invention provides two optional balance adjustment methods:

[0041] Propellant compensation in empty barrel 4: The amount of propellant 9 is increased in the empty barrel 4, and its enhanced reverse force is used to match the recoil increase brought by the extended tube 5. However, this method requires precise calculation of the propellant ratio and customization of the propellant loading process, which is highly complex to implement.

[0042] Dynamic compensation of diffuser: Preferably, a diffuser 6 is installed at the empty gun firing end of the outer tube 1. The diffuser 6 has a flared structure, which can appropriately increase the recoil generated by the empty gun barrel 4, thereby offsetting the additional recoil introduced by the extension tube 5. This method does not require adjustment of the propellant charge and has stronger process adaptability.

[0043] In a preferred embodiment, to ensure safe and reliable transmission of the ignition signal, the side wall of the outer tube 1 is provided with a longitudinally extending lead-out slit 2. The width of this slit is slightly larger than the diameter of the electronic ignition wire 8, and its length covers the installation section of the empty barrel 4 and the effect tube 3. The electronic ignition wire 8 at the tail end of the empty barrel 4 and the electronic ignition wire 8 at the tail end of the effect tube 3 are both led out to the outside of the outer tube 1 through the lead-out slit 2. To achieve synchronous ignition, the electronic ignition wire 8 at the tail end of the empty barrel 4 and the electronic ignition wire 8 at the tail end of the effect tube 3 can be connected in parallel to the output end of the same electronic ignition device. After receiving the ignition command, the ignition device outputs a completely synchronized excitation current to the two electronic ignition wires 8, so that the propellant 9 in the empty barrel 4 and the propellant 9 in the effect tube 3 detonate at the same time, ensuring the timing consistency of the recoil counteraction action.

[0044] According to the UAV fireworks launching system provided by the present invention, such as Figure 1 , Figure 2 As shown, the device includes a drone 12, a mounting frame 11, and the aforementioned firework counter-firing tube 14. The firework counter-firing tube 14 is installed horizontally or obliquely in the mounting frame 11, and the firework launching end and the air cannon launching end of the outer tube 1 extend to the outside of the two sides of the mounting frame 11, respectively. The mounting frame 11 is installed on the top or bottom of the drone 12. Since the outer tube 1 can form a constraint in the counter-firing direction, it is not necessary to adjust the position of the mounting tube on the launcher during the installation process. The firework counter-firing tube 14 only needs to be installed by passing it through the mounting frame 11. The installation is more convenient and flexible, and it allows the firework counter-firing tube 14 to be installed at an angle to the horizontal direction without having to force horizontal installation to take into account the symmetrical launch effect.

[0045] In a preferred embodiment, there are multiple firework launch tubes 14, and the firework launching ends of the outer tubes 1 of the multiple firework launch tubes 14 all face the same side of the mounting frame 11 to form a preset firework effect 13, such as... Figure 1As shown, a single-sided fireworks effect can be achieved under the premise of recoil counteracting. In another preferred embodiment, the fireworks launching ends of the outer tubes 1 of some of the fireworks launching tubes 14 face the mounting frame 11 to form a first preset fireworks effect, while the fireworks launching ends of the outer tubes 1 of the other part of the fireworks launching tubes 14 face the mounting frame 11 to form a second preset fireworks effect. By reversing the installation of some of the fireworks launching tubes 14, fireworks effects in two directions can be achieved simultaneously without being forced to be identical. Different fireworks effects in two directions can be achieved with a single launch.
