Description

Technical Field

[0001] This utility model relates to the field of fireworks launching technology, and more specifically, to a launcher for launching electronically ignited fireworks. Background Technology

[0002] In scenarios where fireworks shells are required, traditional ignition methods typically rely on physical fuses (such as detonators) or require on-site connection to the terminals of an electronic ignition device. These methods have significant drawbacks: when using physical fuses, manual ignition poses a safety hazard due to close contact with a fire source, and the fuse is susceptible to environmental factors, leading to detachment or incomplete combustion, which affects ignition reliability. Furthermore, existing electronic ignition devices often require manual crimping of the power cord of the electronic ignition fuse to the terminals of the launching device on-site, which is cumbersome and time-consuming, making it difficult to meet the needs of rapid deployment. Additionally, there is a risk of accidental contact with high-voltage power during manual wiring.

[0003] Therefore, a solution is urgently needed to address the problems in existing technologies. Utility Model Content

[0004] The main objective of this invention is to provide a launcher for firing electronically ignited fireworks, thereby solving the problems of cumbersome operation and low efficiency caused by the need for manual wiring to connect the electronic ignition fuse in the prior art.

[0005] To achieve the above objectives, this utility model provides a launcher for launching electronically ignited fireworks, comprising a launching mechanism and a power supply control mechanism. The launching mechanism includes a mounting base and multiple launching tubes. The multiple launching tubes are mounted in the mounting base, with each launching tube corresponding to a fireworks projectile. Each launching tube is provided with a positive terminal and a negative terminal. The positive terminal is in contact with the positive terminal of the electronic ignition wire on the fireworks projectile, and the negative terminal is in contact with the negative terminal of the electronic ignition wire on the fireworks projectile. The power supply control mechanism is connected to the launching mechanism and is used to generate a pulse current and apply an instantaneous voltage to the fireworks projectile through the positive and negative terminals, triggering the electronic ignition wire of the fireworks projectile to ignite the projectile body. The power supply control mechanism includes a control cabinet and a solar panel. Each positive wire in the positive wire group of the control cabinet is connected to a corresponding positive terminal, and each negative wire in the negative wire group of the control cabinet is connected to a corresponding negative terminal. The solar panel is electrically connected to the control cabinet to supply power to the control cabinet.

[0006] The positive and negative terminals of the transmitting tube are respectively connected to the positive and negative terminals of the electronic ignition wire via a compression connection.

[0007] Optionally, the mounting base includes:

[0008] A fixed frame, which is a square body with an open upper end, is used to fix multiple transmitting tubes in the fixed frame;

[0009] A protective cover, which is hinged to the opening of the fixed frame;

[0010] An electric push rod, the first end of which is hinged to the side wall of the fixed frame, and the second end of which is hinged to the protective cover; the electric push rod is electrically connected to the power supply control mechanism.

[0011] Optionally, a wind speed sensor and a raindrop sensor are provided on the outer top of the protective cover and are electrically connected to the power supply control mechanism. The power supply control mechanism is used to control the stroke of the electric push rod according to the data detected by the wind speed sensor and the raindrop sensor so that the protective cover covers the transmitter tube or exposes the transmitter tube.

[0012] Optionally, the transmitting tube includes:

[0013] A projectile positioning tube, which is fixed within the fixed frame;

[0014] An insulating sleeve, the bottom of which is screwed to the positioning tube of the projectile;

[0015] Multiple elastic conductive pads are fixed in two layers inside the insulating sleeve along the vertical direction of the insulating sleeve, and each layer is provided with multiple elastic conductive pads evenly distributed along the circumference of the insulating sleeve; the firework cartridge is disposed between the multiple elastic conductive pads.

[0016] The positive terminal is one of the multiple elastic conductive pads connected to the positive wire of the power supply control mechanism, and the negative terminal is one of the multiple elastic conductive pads connected to the negative wire of the power supply control mechanism. When the firework clip is placed between the multiple elastic conductive pads, the positive terminal is in contact with the positive terminal of the electronic ignition wire, and the negative terminal is in contact with the negative terminal of the electronic ignition wire.

[0017] Optionally, multiple support beams are horizontally fixed within the fixed frame, and multiple projectile positioning tubes are uniformly fixed on the upper surfaces of the multiple support beams;

[0018] The adjacent support beams are hollowed out to allow the debris from the explosion of the fireworks, the positive electrode wire, and the negative electrode wire to pass through.

[0019] Optionally, the elastic conductive pad includes:

[0020] A conductive bolt is fixed radially along the insulating sleeve, with one end of the conductive bolt located inside the insulating sleeve.

[0021] The elastic sheet includes a fixed sheet and an arc-shaped spring sheet; one end of the arc-shaped spring sheet is fixed to the fixed sheet, and the other end is a free end that extends in a horizontal direction perpendicular to the axial direction of the insulating sleeve. The free end initially maintains a gap with the inner wall of the insulating sleeve.

[0022] The arc-shaped spring is pre-tightened due to the initial position difference between the fixed end and the free end. When the firework is inserted into the insulating sleeve, the free end is horizontally squeezed by the outer wall of the firework to generate radial displacement, and the firework is clamped in the center of the insulating sleeve by the elastic restoring force.

[0023] Optionally, the power supply control mechanism includes:

[0024] A control cabinet is disposed below the fixed frame. Each positive wire of the positive wire group in the control cabinet is connected to a corresponding positive terminal, and each negative wire of the negative wire group in the control cabinet is connected to a corresponding negative terminal.

[0025] A solar panel is installed on one side of the control cabinet and is electrically connected to the control cabinet to supply power to the control cabinet.

[0026] The control cabinet is used to generate pulse current and apply instantaneous voltage to the bird deterrent projectile through the positive and negative terminals, triggering the electronic ignition wire to ignite the projectile body.

[0027] This utility model discloses a launcher for launching electronically ignited fireworks, comprising a launching mechanism and a power supply control mechanism. The launching mechanism includes a mounting base and multiple launching tubes. The multiple launching tubes are mounted in the mounting base, with each launching tube corresponding to one fireworks. Each launching tube has a positive terminal and a negative terminal. The positive terminal is in contact with the positive terminal of the electronic ignition wire on the fireworks, and the negative terminal is in contact with the negative terminal of the electronic ignition wire on the fireworks. The power supply control mechanism is connected to the launching mechanism and is used to generate pulsed current. A momentary voltage is applied to the firework shell via the positive and negative terminals, triggering the electronic ignition wire to ignite the shell's body. The power supply control mechanism includes a control cabinet and a solar panel. Each positive wire in the positive wire group of the control cabinet is connected to one of the positive terminals, and each negative wire in the negative wire group of the control cabinet is connected to one of the negative terminals. The solar panel is electrically connected to the control cabinet to supply power. The positive and negative terminals in the launching tube are respectively connected to the positive and negative terminals of the electronic ignition wire via a compression connection. This design allows for direct, compression-based electrical connections between the positive and negative terminals of multiple launch tubes and the positive and negative terminals of the electronic ignition wires in the fireworks projectiles. This eliminates the tedious manual wiring process of traditional methods, enabling rapid installation of the fireworks projectiles. Simultaneously, the power supply control mechanism applies instantaneous high-voltage pulse current to the electronic ignition wires via the positive and negative terminals, triggering stable ignition of the fireworks projectiles. This avoids the risk of electric shock from close contact with high-voltage power supplies and the hazard of wire detachment. Combined with solar panels providing clean energy to the control cabinet, it ensures stable instantaneous voltage output, making the fireworks projectiles easy to install, reliable to ignite, and safe to operate.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] like Figures 1-9 As shown, this application provides a launcher for launching electronically ignited fireworks, including a launching mechanism 20 and a power supply control mechanism 30;

[0042] The launching mechanism 20 includes a mounting base 21 and multiple launching tubes 22; the multiple launching tubes 22 are installed in the mounting base 21, and each launching tube 22 corresponds to a firework shell 10; each launching tube 22 is provided with a positive terminal and a negative terminal; the positive terminal is pressed into contact with the positive terminal of the electronic ignition wire 12 on the firework shell 10, and the negative terminal is pressed into contact with the negative terminal of the electronic ignition wire 12 on the firework shell 10.

[0043] The power supply control mechanism 30 is connected to the launching mechanism 20. The power supply control mechanism 30 is used to generate pulse current and apply instantaneous voltage to the firework shell 10 through the positive terminal head and the negative terminal head, triggering the electronic fuse 12 of the firework shell 10 to ignite the shell body 11 of the firework shell 10.

[0044] The power supply control mechanism 30 includes a control cabinet 31 and a solar panel 32. Each positive wire 34 of the positive wire group in the control cabinet 31 is connected to a corresponding positive terminal, and each negative wire 35 of the negative wire group in the control cabinet 31 is connected to a corresponding negative terminal. The solar panel 32 is electrically connected to the control cabinet 31 to supply power to the control cabinet 31.

[0045] The positive and negative terminals of the emitting tube 22 are respectively connected to the positive and negative terminals of the electronic ignition wire via a compression electrical connection.

[0046] Specifically, the firework shell 10 consists of a shell body 11, an electronic ignition wire 12, and an electrostatic protective conductive connection structure. The shell body 11 has pre-drilled holes for inserting the ignition head of the electronic ignition wire 12. When the ignition head of the electronic ignition wire 12 is inserted into the pre-drilled hole on the shell body 11, and a suitable current flows through it, the electronic ignition wire 12 generates high temperature and pressure, thereby igniting the shell body 11. The electrostatic protective conductive connection structure connects to the positive and negative terminals of the electronic ignition wire 12 and fixes them to the outer shell of the shell body 11. This not only fixes the electrode positions and prevents the electrodes from loosening or shifting, but also discharges static electricity from the shell body 11, preventing accidental detonation due to static electricity accumulation and resulting sparks.

[0047] The launching mechanism 20 is used to mount and launch the firework shell 10. The positive and negative terminals are electrically connected to the positive and negative terminals of the firework shell 10 via a compression mechanism. The launching mechanism 20 provides a stable mounting position for the firework shell 10. During installation, the compression action ensures close contact between the power supply terminal of the launching mechanism 20 and the electrodes of the firework shell 10, forming a reliable current path and guaranteeing smooth current transmission from the launching mechanism 20 to the electronic fuse 12 of the firework shell 10. The mounting base 21 in the launching mechanism 20 integrates multiple launching tubes 22 as the main support. When the firework shell 10 is inserted into the corresponding launching tube 22, the positive and negative terminals inside the launching tube 22 respectively compress and contact the positive and negative terminals of the firework shell 10, forming a stable compression electrical contact. Mechanical pressure ensures a tight fit between the contact surfaces, reducing contact resistance and ensuring efficient transmission of the pulse current.

[0048] The power supply control mechanism 30 is connected to the launching mechanism 20 and is used to generate a pulse current. This pulse current is then applied instantaneously to the firework shell 10 via the positive and negative terminals of the launching mechanism 20, triggering the electronic ignition wire 12 to ignite the shell body 11. The power supply control mechanism 30 can precisely control the generation and release timing of the pulse current. The control cabinet 31 is installed in a protective enclosure 33, at a certain distance from the ground. The control cabinet protective box 33 is located at the bottom of the fixed frame 211. The control cabinet 31 serves as the power conversion and distribution center. Each positive wire 34 of the positive wire group inside the control cabinet is securely connected to the positive terminal of the corresponding launch tube 22 through a waterproof aviation connector. Similarly, each negative wire 35 of the negative wire group is connected to the negative terminal of each launch tube 22 in a one-to-one manner, forming a multi-channel independent power supply circuit. The solar panel 32 provides clean energy to the control cabinet 31 through a charging circuit. The energy is converted into the required form of electrical energy by the internal DC-AC inverter and high-voltage pulse generation module. A 60W solar panel 32 at both ends of the control cabinet 31 can provide sufficient power to the high-voltage pulse generation module and the multi-channel power supply circuit inside the cabinet, ensuring stable instantaneous voltage output. When it is necessary to launch the firework shell 10, the pulse generation module inside the control cabinet 31 generates an instantaneous high-voltage current. The instantaneous current enters the launch tube 22, ensuring that each launch tube 22 receives enough energy to independently trigger the electronic fuse 12.

[0049] The launcher for this electronically ignited fireworks projectile directly connects the positive and negative terminals of the electronic ignition wires of the projectile via a compression connection, eliminating the tedious manual wiring process and enabling rapid installation. Simultaneously, the power supply control mechanism applies a momentary high-voltage pulse current to the electronic ignition wires through the positive and negative terminals, triggering stable ignition of the fireworks projectile. This avoids the risk of electric shock from close contact with high-voltage power and the hazard of wire detachment. Combined with a solar panel providing clean energy to the control cabinet, it ensures stable instantaneous voltage output, making the fireworks projectile easy to install, reliable to ignite, and safe to operate.

[0050] The electrostatic protective conductive connection structure in the firework shell 10 includes: a conductive structure 40, which comprises a first conductive sheet 41 and a second conductive sheet 42 that are not in contact with each other. The first conductive sheet 41 covers the positive electrode, and the second conductive sheet 42 covers the negative electrode. The first conductive sheet 41 and the second conductive sheet 42 respectively attach and fix the positive and negative electrodes to the shell of the shell body 11; and an antistatic structure, which is electrically connected to the electronic ignition wire 12 to discharge static electricity from the shell body 11 and prevent accidental ignition of the electronic ignition wire 12. When the firework shell 10 is fixed in the launching mechanism 20, the positive terminal of the launching mechanism 20 is electrically connected to the positive electrode through the first conductive sheet 41, and the negative terminal of the launching mechanism 20 is electrically connected to the positive electrode through the second conductive sheet 42. The independent first conductive sheet 41 and the second conductive sheet 42 respectively cover and attach and fix the positive and negative electrodes of the electronic ignition wire 12 to the shell of the shell body 11, ensuring that the electrode positions are stable and do not loosen, and establishing a direct path for current conduction.

[0051] The anti-static structure forms an electrical connection circuit with the electronic ignition wire 12, which can discharge the static charge accumulated on the surface of the projectile 11 in real time, avoiding accidental detonation caused by high static voltage. When the firework shell 10 is loaded into the launching mechanism 20, the positive and negative terminals of the launching mechanism 20 respectively press against the corresponding first conductive plate 41 and second conductive plate 42, achieving a stable electrical connection to ensure ignition reliability, and ensuring low resistance characteristics when a large current passes through the contact of the conductive plates. At the same time, this embedded fixing method makes the electrode and the shell of the projectile 11 form an integrated structure, effectively preventing electrode displacement caused by transportation vibration. In addition, when loading the firework shell 10, the operator must wear anti-static gloves to ensure electrostatic protection safety. In this application, the first conductive plate 41 and the second conductive plate 42 are sheet-shaped and are double-sided conductive plates. Before the firework shell 10 is loaded into the launching mechanism 20, an insulating protective film can be covered on the surface of the first conductive sheet 41 and the second conductive sheet 42 of the electrostatic protective conductive connection structure to reduce the accumulation of static electricity in the shell 11 due to friction or air discharge during transportation or storage through physical isolation; when the firework shell 10 is ready to be loaded, the insulating protective film is removed to expose the conductive sheet directly, ensuring that the launching mechanism 20 can form an effective electrical connection through compression contact during installation.

[0052] The positive terminal is the end of the positive lead 121 of the electronic ignition wire 12, and the negative terminal is the end of the negative lead 122 of the electronic ignition wire 12. The anti-static structure includes: a normally closed switch 50, the first ends of the positive and negative leads of the normally closed switch 50 are respectively connected to the two ends of the normally closed contacts inside the normally closed switch 50; the positive lead is connected to the middle of the positive lead 121, and the negative lead is connected to the middle of the negative lead 122; wherein, before the firework shell 10 is loaded into the launching mechanism 20, the normally closed contacts are closed; after the firework shell 10 is loaded into the launching mechanism 20, the pressure cap 51 is pressed down, the normally closed contacts are opened, and the positive and negative leads are separated. In this design, the positive pin of the normally closed switch 50 is directly soldered to the positive lead 121 of the electronic ignition wire 12, and the negative pin is directly soldered to the negative lead 122 of the electronic ignition wire 12. The first ends of the positive and negative pins form a conductive circuit through an internal normally closed contact, causing the positive and negative terminals of the electronic ignition wire 12 to be in a short-circuit state. Static charges generated on the surface of the projectile 11 due to friction or induction can be directly introduced into the internal discharge channel of the electronic ignition wire 12 through this short-circuit path. When it is necessary to load the firework shell 10, the operator presses the pressure cap 51, which pushes the normally closed contact to mechanically separate, cutting off the electrical connection between the positive and negative pins. The firework shell 10 is then loaded into the launching mechanism 20. The first conductive plate 41 and the second conductive plate 42 in the launching mechanism 20 respectively press and fix the positive and negative terminals of the electronic ignition wire 12. The pulse current of the power supply control mechanism 30 passes through the positive terminal of the launching mechanism 20, the first conductive plate 41, the positive terminal, the electronic ignition wire 12, the negative terminal, the second conductive plate 42, and the negative terminal to form a complete circuit, and the firework shell 10 can be launched normally.

[0053] The anti-static structure includes a fusible structure, with its two ends connected to a first conductive plate 41 and a second conductive plate 42, respectively. The maximum current carrying capacity of the fusible structure is less than the current required for the electronic ignition wire 12 to ignite. When the pulse current applied by the launching mechanism 20 through the positive and negative terminals exceeds the maximum current carrying capacity of the fusible structure, the fusible structure will automatically melt instantly. The two ends of the fusible structure are connected to the first conductive plate 41 and the second conductive plate 42. During the pre-loading static discharge stage, when static charge is generated on the surface of the projectile 11 due to friction or induction, the fusible structure has a low fusing current threshold, and its resistance is much lower than the impedance of the normal ignition circuit of the electronic ignition wire 12, forming a preferential conduction path. This allows the static charge to be quickly discharged into the electronic ignition wire 12 through this low-impedance channel, preventing accidental detonation caused by static accumulation. When the launching mechanism 20 applies a pulse current, since the maximum current carrying capacity of the fusible structure is less than the current required for the electronic ignition wire 12 to ignite, the instantaneous large current will directly melt the fusible structure, forcibly cutting off the electrostatic discharge path. This ensures that the pulse current can only form a complete ignition circuit through the electronic ignition wire 12 itself. This avoids the energy diversion problem caused by the parallel connection of the electrostatic discharge path and the ignition circuit, and also prevents the high voltage pulse from leaking through the low impedance discharge path and causing false triggering, thus achieving precise separation of electrostatic protection and ignition control.

[0054] The first type of fusible structure includes a fuse 60, with its two ends connected to a first conductive piece 41 and a second conductive piece 42 via conductive connectors. The fuse 60 consists of a molten metal element, an insulating shell, and conductive connectors at both ends. The molten metal element, serving as both the conductive and fusing component, is made of a low-melting-point alloy material, and its cross-sectional area and length are designed according to a preset fusing current value. The insulating shell encloses the molten metal element to provide electrical isolation protection. The conductive connectors at both ends are permanently electrically connected to the first conductive piece 41 and the second conductive piece 42 via welding or crimping, respectively. During the electrostatic discharge stage before loading, the fuse 60 exhibits extremely low impedance due to the low melting point of the molten metal, forming an electrostatic discharge channel that takes precedence over the normal ignition circuit of the electronic ignition wire 12. This allows the electrostatic charge on the surface of the projectile 11 to be quickly introduced into the discharge channel inside the electronic ignition wire 12 via this path. When the firing mechanism 20 applies a pulse current, the Joule heat generated by the instantaneous large current in the molten metal rapidly exceeds its melting point threshold, melting and vaporizing within microseconds, forming an irreversible open circuit state. This forcibly cuts off the electrostatic discharge path, ensuring that the pulse current can only form an ignition circuit through the impedance of the electronic ignition wire 12 itself, thus achieving functional isolation between electrostatic protection and ignition control.

[0055] In this application, the fuse 60 can be a resistance fuse 60. The two ends of the resistance fuse 60 are respectively bonded to the positive and negative conductive copper foils. Before the firework shell 10 is used, the resistance fuse 60 connects the positive and negative terminals to form a short circuit. The ignition current of the resistance wire is about 0.4A, while the electrostatic current is mostly in the microamp (μA, 10-6A) range, which cannot melt the resistance wire, thus playing an anti-static role. During normal launch, when the power cord is connected, the current is generally between 1-5A, which will quickly melt the resistance wire, connect the positive and negative terminals of the shell 11, and ignite the firework shell 10.

[0056] The second type of fusible structure includes a third conductive sheet 70, with its two ends connected to a first conductive sheet 41 and a second conductive sheet 42, respectively. The third conductive sheet 70, the first conductive sheet 41, and the second conductive sheet 42 are made of the same material. The area of ​​the third conductive sheet 70 is smaller than that of the first conductive sheet 41 and also smaller than that of the second conductive sheet 42. The two ends of the third conductive sheet 70 are electrically connected to the first conductive sheet 41 and the second conductive sheet 42 via conductive adhesive. Because the cross-sectional area of ​​the third conductive sheet 70 is smaller than that of the first and second conductive sheets 41 connected to it, it has a higher current density under the same current conditions, resulting in increased local resistance and concentrated heat generation. When the emitting mechanism 20 applies a pulsed current, the third conductive sheet 70 rapidly melts due to its inability to withstand the Joule heating effect generated by the instantaneous large current, forming an irreversible open circuit state, thereby cutting off the electrostatic discharge path. During the electrostatic discharge stage before loading, the electrostatic current flowing through the third conductive sheet 70 is relatively small, and its temperature rise is within a safe range, which can maintain stable conductivity and achieve the dual functions of electrostatic safety discharge and high voltage isolation.

[0057] In this application, the first conductive sheet 41, the second conductive sheet 42 and the third conductive sheet 70 are all sheet-like structures with one side coated with conductive adhesive, and the material is one of conductive copper foil, composite copper foil, gold-plated copper foil, copper-clad aluminum foil, conductive polymer and graphene foil.

[0058] In one possible implementation, the mounting base 21 includes:

[0059] The fixed frame 211 is a square body with an open upper end, and multiple emission tubes 22 are fixed in the fixed frame 211.

[0060] Protective cover 212 is hinged to the opening of fixed frame 211;

[0061] Electric push rod 213, the first end of electric push rod 213 is hinged to the side wall of fixed frame 211, and the second end of electric push rod 213 is hinged to protective cover 212; electric push rod 213 is electrically connected to power supply control mechanism 30.

[0062] Among them, the top outer side of the protective cover 212 is provided with a wind speed sensor and a raindrop sensor that are electrically connected to the power supply control mechanism 30. The power supply control mechanism 30 is used to control the stroke of the electric push rod 213 according to the data detected by the wind speed sensor and the raindrop sensor so that the protective cover 212 covers the transmitter tube 22 or exposes the transmitter tube 22.

[0063] Specifically, the fixed frame 211, serving as the main load-bearing structure, is a square-shaped structure with an open upper surface. Multiple parallel-arranged launch tubes 22 are fixed inside the square structure via positioning slots or clips. The protective cover 212 is hinged to the opening of the fixed frame 211. Specifically, one edge of the protective cover 212 is connected to the top edge of the fixed frame 211 via a stainless steel hinge, forming an openable and foldable flip-up structure. The electric push rod 213 extends to push the protective cover 212 to flip upwards around the hinge axis. A travel limit ensures that the angle between the protective cover 212 and the open plane of the fixed frame 211 after unfolding is ≥90°. Its first end is hinged to an L-shaped bracket on the side wall of the fixed frame 211 via a universal joint, and its second end is connected to the top edge of the protective cover 212 via a ball joint, forming a push-pull mechanism with dual degrees of freedom adjustment, ensuring that the protective cover 212 maintains a planar motion trajectory during opening and closing. The electric actuator 213 is electrically connected to the power supply control mechanism 30 via a waterproof cable. The cable is led to the top of the protective cover 212 through a cable tray inside the fixed frame 211. The electric actuator is prior art, and its specific details will not be elaborated in this application.

[0064] In one possible implementation, a wind speed sensor and a raindrop sensor are provided on the outer top of the protective cover and are electrically connected to a power supply control mechanism. The power supply control mechanism is used to control the stroke of the electric push rod based on the data detected by the wind speed sensor and the raindrop sensor to cover or expose the transmitter tube.

[0065] A wind speed sensor and a raindrop sensor are installed on the outer top of the protective cover 212, and both are connected to the power supply and control mechanism 30 via an aviation connector with an IP67 protection rating. The impeller assembly of the wind speed sensor is vertically mounted in the center of the top of the protective cover 212 and fixed by a magnetic base; the sensing plate of the raindrop sensor is horizontally embedded in the front edge of the top of the protective cover 212 and is waterproofed by a silicone sealing ring. After receiving the sensor signal, the power supply and control mechanism 30 drives the electric push rod 213 to extend or retract according to a preset threshold (such as wind speed > 8 m / s or raindrop signal lasting 5 seconds). The push rod stroke is controlled by a limit switch. When fully extended, it pushes the protective cover 212 to flip to a horizontal state to expose the launch tube 22. When fully retracted, it causes the protective cover 212 to flip downward around the hinge axis to completely cover the opening of the fixed frame 211, thereby covering the launch tube 22 and realizing the automated switching between environmental protection and launch preparation.

[0066] In one possible implementation, the transmitting tube 22 includes:

[0067] Projectile positioning tube 221, which is fixed inside the fixed frame 211;

[0068] Insulating sleeve 222, the bottom of which is screwed to the projectile positioning tube 221;

[0069] Multiple elastic conductive pads 223 are fixed in two layers inside the insulating sleeve 222 along the vertical direction of the insulating sleeve 222, and each layer is provided with multiple elastic conductive pads 223 evenly distributed along the circumference of the insulating sleeve 222; the firework shell 10 is sandwiched between the multiple elastic conductive pads 223.

[0070] Among the multiple elastic conductive pads 223, the elastic conductive pad 223 connected to the positive wire 34 of the power supply control mechanism 30 is the positive terminal, and the elastic conductive pad 223 connected to the positive wire 34 of the power supply control mechanism 30 is the negative terminal; when the firework shell 10 is sandwiched between the multiple elastic conductive pads 223, the positive terminal is in contact with the first conductive sheet 41, and the negative terminal is in contact with the second conductive sheet 42.

[0071] Specifically, multiple support beams 214 are fixed horizontally within the fixed frame, and the projectile positioning tube 221 is evenly fixed on the top of the support beams 214. The insulating sleeve 222 is installed on the positioning tube through a bottom threaded connection, which facilitates the installation and replacement of the insulating sleeve and saves costs. Multiple elastic conductive pads 223 are arranged in two layers along the vertical direction of the insulating sleeve 222, and each layer is evenly distributed circumferentially to form a clamping space for the firework shell 10. When the firework shell 10 is loaded into the launch tube 22, the elastic conductive pads 223 compress the shell of the projectile 11, so that the positive terminal of the electronic ignition wire 12 forms a stable contact with the positive terminal end connected to the positive terminal wire 34 of the power supply control mechanism 30, and the negative terminal forms a stable contact with the negative terminal end connected to the negative terminal wire 35 of the power supply control mechanism 30, ensuring that the pulse current forms a complete ignition circuit through the electronic ignition wire 12.

[0072] The insulating sleeve 222 is fixed to the projectile positioning tube 221 by a bottom threaded connection, which physically isolates the metal projectile positioning tube 221 from the conductive components inside, including the elastic conductive pad 223 and the second positive and negative end heads.

[0073] In this application, three elastic conductive pads 223 are installed on each layer. The three elastic conductive pads 223 are evenly distributed on the insulating sleeve 222 in a 120° circle, achieving balanced three-point positioning and clamping of the firework shell 10, avoiding partial loose connection of the firework shell 10 and causing ignition failure. This ensures that the shell body 11 is centered and stable and makes reliable contact with the positive and negative terminals, improving the stability and consistency of the ignition circuit connection.

[0074] In one possible implementation, multiple support beams 214 are horizontally fixed inside the fixed frame 211, and multiple projectile positioning tubes 221 are uniformly fixed on the upper surface of the multiple support beams 214.

[0075] The adjacent support beams 214 are hollowed out to allow the debris, positive wire 34 and negative wire 35 to pass through after the fireworks shell 10 explodes.

[0076] Specifically, multiple support beams 214 are horizontally arranged within a fixed frame to fix the projectile positioning tube 221, and the adjacent support beams 214 are designed with open spaces. This achieves stable positioning and uniform distribution of the firework shell 10, ensures the smooth falling of debris after the firework shell 10 explodes, and allows the safe passage of the positive and negative wires 34 and 35. This effectively prevents debris accumulation from affecting the normal operation of the launching mechanism 20, while reducing the risk of poor contact between the positive and negative wires 34 and 35 due to debris covering, thus improving the overall safety and reliability of the launching device.

[0077] In one possible implementation, the elastic conductive pad 223 includes:

[0078] The conductive bolt 2231 is fixed radially along the insulating sleeve 222, and one end of the conductive bolt 2231 is located inside the insulating sleeve 222.

[0079] The elastic sheet 2232 includes a fixed sheet and an arc-shaped spring sheet; one end of the arc-shaped spring sheet is fixed on the fixed sheet, and the other end is a free end that extends in a horizontal direction perpendicular to the axial direction of the insulating sleeve 222. The free end initially maintains a gap with the inner wall of the insulating sleeve 222.

[0080] The arc-shaped spring sheet is pre-tightened due to the initial position difference between the fixed end and the free end. When the firework shell 10 is inserted into the insulating sleeve 222, the free end is horizontally squeezed by the outer wall of the firework shell 10, resulting in radial displacement. The elastic restoring force is used to clamp the firework shell 10 at the center position of the insulating sleeve 222.

[0081] Specifically, the elastic conductive pad 223 consists of a radially fixed conductive bolt 2231 and an elastic plate 2232. The elastic plate 2232 includes a fixed plate and an arc-shaped spring piece. One end of the arc-shaped spring piece is fixed, and the free end initially maintains a gap with the inner wall of the insulating sleeve 222, forming a pre-tightened state. When the firework shell 10 is inserted, the outer wall of the shell body 11 compresses the free end of the arc-shaped spring piece, causing it to generate radial displacement and store elastic potential energy. Subsequently, the elastic restoring force drives the free end to rebound, precisely clamping the firework shell 10 at the center position of the insulating sleeve 222, while ensuring stable contact with the conductive bolt 2231. Multiple symmetrically distributed elastic plate 2232 units can also automatically correct loading deviations, improving ignition reliability. Figure 9As shown, the dashed elastic sheet 2232 represents the state before compression, while the solid elastic sheet 2232 represents the compressed state.

[0082] In this application, the control cabinet 31 can control and realize multiple functions such as single firing, continuous firing, and simultaneous firing. The control cabinet 31 contains an array of independent positive and negative relays (e.g., 16-tube arrays correspond to 32 relays) matching the number of transmitter tubes 22. The positive wire 34 and negative wire 35 of each transmitter tube 22 are connected to independent positive and negative relays, respectively. All relays are directly controlled by the independent digital I / O ports of the PLC, forming a completely electrically isolated switching network, thus realizing flexible firing modes. In single firing mode, the PLC only closes the positive and negative relays of the target tube, and the high-voltage pulse forms an independent circuit through the corresponding wires. In continuous firing mode, multiple tube relay groups are triggered sequentially at preset intervals to achieve time-sharing ignition. In simultaneous firing mode, the relays of the selected tubes are closed synchronously, and high-voltage pulses are synchronously applied through multiple positive and negative wires 35 to achieve simultaneous ignition of multiple tubes. The control cabinet 31 is based on a 16-unit assembly (32 relays). By increasing the number of relay groups (e.g., 64 relays for 32 tubes, 96 relays for 48 tubes) and expanding the PLC digital I / O ports, along with a unified splitter layout and standardized control algorithms, it can seamlessly adapt to various combinations of 22 transmitter tubes, such as 16, 32, 48, 64, and 80 tubes, to meet the needs of large-scale deployment in different scenarios.

[0083] The device in this application is equipped with two levels of protection: a main switch and a remote control switch. The main switch acts as a physical isolation device; when closed, it only connects the basic power supply to the control cabinet 31 (such as low-voltage circuits like the PLC and sensors), while the high-voltage pulse generation module remains de-energized. The remote control switch acts as an electronic security key, requiring wireless / wired signal interaction with the security logic unit within the control cabinet 31. Only when the main switch is closed and the remote control switch is actively activated (e.g., by pressing the start button on the remote control) will the security logic unit send an enable signal to the high-voltage pulse generation module, allowing it to receive ignition commands. The two switches form an AND gate logic relationship; if either is not closed (either the main switch is open or the remote control switch is not activated), the power supply to the high-voltage pulse module will be blocked, completely eliminating the risk of accidental triggering.

[0084] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
