[0021] The present invention aims at the problems and shortcomings of the existing fireworks drones, and provides a coaxial rotor cannon-firing fireworks drone system. The fireworks drone is launched to a specified height for hovering by an air cannon, thereby saving the power consumption of the drone for launching, and solving the problems of short flight time and slow launch speed of the drone. The fireworks drone's ammunition load is increased by a fireworks launch tube to meet the requirement that a small number of micro drones can complete the effect of a large-scale fireworks show. At the same time, the fireworks launch tube also plays the function of protecting the drone and assisting its landing. The firing angle and firing direction of the fireworks are adjusted by a steerable fireworks launch head, so as to assist in completing the design of highly controllable fireworks patterns, and solve the shortcomings of the fireworks drone's single performance pattern and the inability to control the performance effect of the fireworks show in real time.

[0022] like Figure 1As shown, the present invention proposes a coaxial rotor artillery fireworks UAV system, including a missile-borne shell, a UAV and a foldable fireworks guidance and launch system; the missile-borne shell mainly includes a missile body 1, a tail 2 and a wind cap 3, the missile body 1 and the tail 2 are connected by a fixing mechanism, and a shell ejection mechanism is arranged in the fixing mechanism, and shell ejection and separation can be realized when a separation signal is received; the overall structure composed of the UAV and the foldable fireworks guidance and launch system is placed inside the missile body 1 in a folded state; the UAV is composed of a foldable nose 14 and a fuselage 15; the foldable fireworks guidance and launch system is composed of a directional fireworks launch device and an airborne fireworks launch rack, the airborne fireworks launch rack includes a fireworks launch tube 10 and a foldable cross connecting rod, the fireworks launch tube 10 is connected to the UAV through the foldable connecting rod, and fireworks projectiles and propellants are installed inside, which are carried into the sky by the UAV and remotely controlled, and the fireworks are ignited and launched by an electric ignition method.

[0023] The steerable fireworks launching device and the airborne fireworks launching rack are also a kind of protective device for the unmanned aerial vehicle. The protective device can not only load fireworks projectiles, but also prevent the unmanned aerial vehicle from coming into close contact with the fireworks in the fireworks launching tube (10), thereby reducing the heat conducted into the unmanned aerial vehicle, and can ensure the safe landing of the unmanned aerial vehicle, thereby protecting the unmanned aerial vehicle.

[0024] An ignition circuit is fixed on the airborne fireworks launcher, and the ignition circuit is composed of a battery, a receiver, and an electric ignition wire. The fireworks launch effect is controlled by controlling the electric ignition wire to achieve programmable fireworks patterns; the electric ignition wire is buried inside the fireworks launch tube 10. When the receiver receives a specified signal, the electric ignition wire ignites the propellant in the fireworks launch tube 10 to launch a fireworks projectile.

[0025] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the projectile body 1 and the projectile tail 2 protruding parts are provided with four equidistant and same-diameter small holes, which are fixedly connected by a pin 18. At the same time, a shell ejection mechanism is provided at the connection between the above two, which includes an electric ignition device 16 and an ejection block 17. Among them, the electric ignition device 16 is of cylindrical design, and a slender electric ignition wire is extended from the device to the hollow part inside the ejection block, and a small amount of gunpowder is filled in the hollow part. The ejection block 17 is embedded in the groove surrounded by the protruding part of the projectile tail, and its side wall and the protruding part of the projectile tail are respectively provided with four equidistantly arranged small holes of the same diameter. The pin 18 thus connects and fixes the projectile body, the projectile tail and the ejection block at the same time.

[0026] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the wind hood 3 is nested into the top of the projectile body 1 through its own protruding part, and the overall structure consisting of the drone and the foldable fireworks guidance and launching system is placed in a folded state in a closed space consisting of the projectile body 1, the tail 2 and the wind hood 3.

[0027] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the present invention uses an air cannon launch device to launch the entire system consisting of the bomb-borne shell, drone and foldable fireworks guidance launch system into the air. Before launching, the air cannon is loaded with the tip of the wind cap as the exit direction. When the launch signal is issued, the air cannon uses high-pressure gas to push the system of the present invention to launch in a predetermined direction.

[0028] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, an ejection mechanism is installed between the projectile body 1 and the projectile tail 2 of the projectile-borne shell. When the system of the present invention reaches the specified height and angle, the electric ignition device 16 ignites the pre-loaded gunpowder in the ejection block 17 through the extended electric ignition wire. The ejection block 17 is made of PLA material and 3D printed, and the bottom of the hollow part is very thin. The ignited gunpowder will directly explode the bottom of the ejection block 17, and the ejection block 17 will be pushed upward by the gunpowder expansion gas. Then the ejection block 17 will directly hit the drone and the foldable fireworks guide launch system in the folded state, driving the whole to continue to move upward and push out the wind cap 3. The purpose of releasing the drone and the fireworks launch system in the folded state is achieved.

[0029] Furthermore, in the above-mentioned coaxial rotor artillery fireworks UAV system, the UAV is composed of two foldable heads 14 and a fuselage 15, and the upper and lower coaxially distributed UAV heads 14 improve space utilization and facilitate the installation of a foldable fireworks launcher.

[0030] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, a foldable cross connecting rod is fixed through the middle of the drone fuselage, and the foldable cross connecting rod is formed by connecting a cross center rod 12 and a cross folding rod 11. The cross center rod 12 is fixed through the center of the drone fuselage and is connected to the cross folding rod in a hinged manner with a pin.

[0031] Furthermore, in the above-mentioned coaxial rotor artillery fireworks UAV system, the fireworks launching tube 10 is connected to the cross folding rod 11 through a hinge, and there are four fireworks launching tubes in total, which are respectively fixed at one end of the four cross folding rods in the middle.

[0032] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the upper and lower ends of the four fireworks launching tubes are still connected to the cross-shaped foldable cross connecting rods through hinges, and the upper, middle and lower sections of the airborne fireworks launching tubes are each fixed with a foldable cross connecting rod. This connection method stabilizes the position of the airborne fireworks launching tubes and is not easy to cause deviation.

[0033] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the foldable cross connecting rod can be folded and tightened centripetally, loaded in the shell, and unfolded after the shell is ejected, until the drone completes the performance and lands safely.

[0034] Furthermore, in the above-mentioned coaxial rotor artillery fireworks UAV system, the foldable cross connecting rod and the four airborne fireworks launching tubes constitute an airborne fireworks launching rack, forming a foldable cage structure, which covers the UAV. While loading fireworks projectiles, it prevents the UAV from close contact with the fireworks in the fireworks launching tubes, ensures the safe landing of the UAV, and protects the UAV.

[0035] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the steerable fireworks launching device is composed of a guide head 4, a fixed head 9, a latch, a rotating shaft 6, a steering gear and a matching power supply battery. The upper half body is the guide head 4, and the lower half body is the fixed head 9. The fixed head 4 is fixed to the pipe mouth of the fireworks launching tube, and the entire steerable fireworks launching device is fixed to the airborne fireworks launching frame. The guide head 4 and the fixed head 9 are connected by a hinge. Under the control of the steering gear, the guide head 4 can swing to realize the change of the relative angle between the upper and lower parts.

[0036] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the guide head 4 and the fixed head 9 in the steerable fireworks launch device are made of lightweight composite materials, and the central tube holes of the guide head 4 and the fixed head 9 are embedded with a high-temperature resistant hose 5, and the hose is bent following the change in the relative angle between the upper and lower heads. The fireworks powder beads are vertically ejected upward along the fireworks launch tube, and after passing through the flexible hose, they are ejected along the bending direction of the hose, realizing the change of the launch trajectory of the fireworks powder beads themselves, while preventing excessive deformation caused by the heat generated by the fireworks, and ensuring stable and precise control of the launch angle.

[0037] Furthermore, in the above-mentioned coaxial rotor artillery fireworks UAV system, the steerable fireworks launching device is fixed to the launching port at the top of the airborne fireworks launching tube by bolts.

[0038] Furthermore, in the above-mentioned coaxial rotor artillery fireworks drone system, the steering of the rotating shaft 6 in the steerable fireworks launching device is controlled by the servo 8. After receiving the specified signal, the servo 8 drives the steerable fireworks launching device to deflect in a predetermined direction, thereby controlling the direction of the fireworks launch, so that a small number of drones can create rich fireworks patterns.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example

[0041] like Figure 1-Figure 7As shown, an embodiment of the present invention provides a cannon-launched coaxial rotor fireworks UAV system, which includes a missile-borne shell, a UAV and a foldable fireworks guidance and launch system.

[0042] The shell of the bullet mainly includes a body 1, a tail 2 and a cap 3. The protruding parts of the body 1 and the tail 2 are provided with four equidistant and same-diameter small holes, which are fixedly connected by a pin 18. The connection between the two is provided with an ejection mechanism, which includes an electric ignition device 16 and an ejection block 17. The electric ignition device 16 is cylindrical in design, and a thin electric ignition wire is extended from the device to the hollow part inside the ejection block 17, and a small amount of gunpowder is filled in the hollow part, such as Figure 7 As shown. The ejection block 17 is fitted into the groove formed by the protruding part of the tail 2, and its side wall and the protruding part of the tail 2 are respectively provided with four equally spaced small holes of the same diameter as described above. The pin 18 thereby connects and fixes the projectile body 1, the tail 2 and the ejection block 17 at the same time. The wind cap 3 is embedded into the top of the projectile body 1 through its own protruding part, and the overall structure consisting of the drone and the foldable firework guidance and launch system is placed in a closed space consisting of the projectile body 1, the tail 2 and the wind cap 3 in a folded state.

[0043] In this embodiment, the drone is composed of a foldable nose 14 and a fuselage 15 , wherein a cross center rod 12 is fixedly passed through the middle of the fuselage 15 and is connected to the cross folding rod 11 in a hinged manner in conjunction with a No. 2 latch 13 .

[0044] In this embodiment, the foldable fireworks guide launch system includes a guideable fireworks launch device and a fireworks launch stand. The guideable fireworks launch device is mainly composed of a guide head 4, a high temperature resistant hose 5, a rotating shaft 6, a No. 1 pin 7, a steering gear 8 and a fixed head 9. The guide head 4 cooperates with the rotating shaft 6 and the No. 1 pin 7 and is connected to the fixed head 9 in a hinged form. The outer side of the rotating shaft 6 is connected to the steering gear, and the steering gear controls the rotation to control the rotation angle of the guide head 4. The fixed head 9 is nested and fixed at the top of the fireworks launch tube 10, and the connecting axis of the steering gear 8 and the rotating shaft 6 is kept pointing to the outside of the system and perpendicular to the UAV fuselage, so as to ensure that the angle between the guide head 4 and the fixed head 9 is deflected at the correct angle during operation. The fireworks launch stand includes a fireworks launch tube 10, a cross folding rod 11, a cross center rod 12 and a No. 2 pin 13. The fireworks launch tube 10 is parallel to the vertical direction of the UAV fuselage and is arranged in the front, back, left and right directions of the UAV. The firework launch tube 10 is provided with a cross folding rod 11 at the top, middle and bottom respectively, which is hingedly connected with the second latch pin 13 and further connected with the cross center rod 12 located in the center.

[0045] In this embodiment, the system of the present invention will be used to launch the air cannon Figure 1The whole system shown is launched into the air. Before launching, the air cannon is loaded with the tip of the wind cap 3 as the exit direction. When the launch signal is issued, the air cannon uses high-pressure gas to push the system of the present invention to launch in a predetermined direction.

[0046] In this embodiment, a push-out mechanism is installed between the projectile body 1 and the projectile tail 2 of the projectile-carrying shell. Figure 7 As shown, when the system of the present invention reaches the specified height and angle, the electric ignition device 16 ignites the pre-loaded gunpowder in the ejection block 17 through the extended electric ignition wire. Since the ejection block 17 is made of PLA material and 3D printed, and the bottom of the hollow part is very thin, the ignited gunpowder will directly explode the bottom of the ejection block 17, and the ejection block 17 will be pushed upward by the expansion gas of the gunpowder. Then the ejection block 17 will directly hit the folded drone and the foldable fireworks guide launch system, driving the whole to continue to move upward and push out the hood 3. The release is achieved as shown in FIG. Figure 2 The drone is shown in a folded state and is intended for use with a fireworks launch system.

[0047] In this embodiment, the drone and the fireworks launch tube and the four fireworks launch tubes are connected by a foldable cross connecting rod composed of a cross folding rod 11, a cross center rod 12 and a second pin. When the drone and the fireworks launch system are separated from the missile body 1, the three groups of foldable cross connecting rods will jointly drive the four groups of fireworks launch tubes in front, behind, left and right to unfold off-axis relative to the center axis of the drone. Figure 4 As shown, after unfolding, the fireworks launch tube 10 will remain parallel to the surface of the drone body 15 to ensure the stability of the fireworks launch. At the same time, the three groups of foldable cross connecting rods and the four groups of fireworks launch tubes together form a cage structure, which surrounds the drone body. To a certain extent, the drone is protected and acts as a landing gear when the drone lands. The cross foldable structure can play a buffering role when the drone lands, protecting the safety of important precision parts inside the drone.

[0048] In this embodiment, a circular ring-shaped thin sheet is connected below the steering gear 8. The thin sheet is located just below the fixing head 9 and is nested on the firework launching tube 10 to fix the firework, thereby ensuring the stable operation of the steering gear 8.

[0049] In this embodiment, a micro ignition circuit is fixed on the fireworks launcher. The ignition circuit is composed of a battery, a receiver, and an electric ignition wire. The electric ignition wire is buried inside the fireworks launch tube 10. When the receiver receives a specified signal, the electric ignition wire ignites the propellant in the fireworks launch tube 10 and launches a fireworks projectile, thereby realizing the fireworks launch at a specified time on the drone.

[0050] In this embodiment, when the firing angle of the fireworks projectile needs to be changed, the steering gear 8 controls the guide head 4 to deflect to a predetermined angle through the rotating shaft 6, thereby driving the high temperature resistant hose 5 to bend, changing the firing path of the fireworks projectile, and realizing the ejection control of the fireworks projectile. The high temperature resistant hose 5 is made of a special high temperature resistant material to ensure that the normal operation of the hose and other key components of the guide fireworks launch device is not affected under the high temperature condition of multiple firings of fireworks projectiles.

[0051] Before launching the UAV, the prepared fireworks projectiles and propellant are loaded into the fireworks launch tube 10, and an ignition wire is buried in the fireworks launch tube 10, and then Figure 1 The coaxial rotor gun-fireworks drone is folded and loaded into the bomb body 1, and then Figure 1 The shells to be fired, including the whole system, are loaded into the air cannon launcher for preparation. After the launch angle and height of the air cannon are calculated, the shells are fired to the designated height and location, and then the UAV and the foldable fireworks guide launch system are pushed out and released by the shell pusher. Figure 3 The fireworks launch tube 10 of the fuselage is unfolded and hovered. After the drone hovers, it begins to prepare for the fireworks show. The fireworks release in this embodiment is remotely controlled by a micro ignition circuit fixed on the fireworks launcher, wherein the ignition circuit includes: a battery, a receiver, and an electric ignition wire. When releasing the fireworks, a control signal is transmitted from the ground at a predetermined time. After receiving the signal, the receiver ignites the electric ignition wire buried in the fireworks launch tube 10, thereby igniting the fireworks propellant to release the fireworks projectile. At the same time, the external receiver of the servo 8 receives the designated signal and adjusts the deflection of the guide head 4 according to the idea of ​​the predetermined fireworks pattern to adjust the launch direction of the fireworks and produce the predetermined fireworks pattern. Through the scheme in this embodiment, a variety of fireworks patterns can be produced, achieving the goal of completing multiple large-scale fireworks shows with a small number of drones.
