Description

Technical Field

[0001] This utility model relates to the technical field of fireworks display equipment, and in particular to an ignition device for a fireworks display rack. Background Technology

[0002] During fireworks displays, a safe and efficient ignition method is crucial. Traditional fireworks ignition methods, such as manually holding an ignition tool close to the fuse, pose significant safety risks, as operators are susceptible to injury from accidental explosions. With technological advancements, electronic ignition devices have emerged.

[0003] Existing ignition devices for fireworks display racks connect the ignition module and the fireworks fuse by inserting the fireworks fuse into the interface of the ignition device. This lacks corresponding fixing measures, which may cause the fireworks fuse to loosen during the display, thus preventing the fireworks from being set off normally. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an ignition device for a fireworks display stand, which can fix the fireworks fuse, thereby avoiding the possibility of the fireworks fuse becoming loose during the display process, thus ensuring that the fireworks can be displayed normally, and effectively solving the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

The top of the ignition chamber has a lead wire inlet. The ignition chamber is a transparent structure. Two sets of clamping mechanisms are installed on the inner side of the ignition chamber. The two sets of clamping mechanisms are arranged symmetrically on the left and right. The end of the clamping mechanism is fixed with a mounting base. A pressure wheel is rotatably installed on the mounting base. The PLC controller is electrically connected to the power supply and the electronic igniter respectively.

[0007] Furthermore, the clamping mechanism includes a movable rod and a limiting block. The movable rod is movably connected to the ignition chamber, the limiting block is fixed to the outer end of the movable rod, and the mounting seat is fixed to the inner end of the movable rod.

[0008] Furthermore, the clamping mechanism also includes a spring, which is sleeved on the movable rod and disposed between the mounting base and the ignition chamber.

[0009] Furthermore, it also includes a heat insulation layer, which is disposed on the surface of the pressure roller and is a ceramic fiber reinforced polyetheretherketone layer.

[0010] Furthermore, it also includes anti-slip strips, the anti-slip strip rotation array being fixed on the pressure roller.

[0011] Furthermore, the anti-slip strips on the pressure rollers located at symmetrical positions on the left and right sides are arranged alternately.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This ignition device for fireworks display rack has the following advantages:

[0013] 1. The ignition process takes place inside the ignition chamber, thereby reducing the influence of the external environment on the ignition process. The ignition chamber is a transparent structure, allowing observation of the insertion point of the fireworks fuse.

[0014] 2. The pressing mechanism presses the firework fuse with a pressure roller, which can fix the firework fuse and prevent it from loosening during the ignition process, thus ensuring that the firework can be ignited normally. Attached Figure Description

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0021] Please see Figure 1-4This embodiment provides a technical solution: an ignition device for a fireworks display stand, including a frame 1. A power supply 2 and a PLC controller 3 are respectively installed on the side of the frame 1. An ignition chamber 11 and an electronic igniter 4 are respectively installed on the frame 1, and the ignition chamber 11 and the electronic igniter 4 are arranged in a one-to-one correspondence. The top of the ignition chamber 11 has a lead wire inlet 10. The ignition chamber 11 is a transparent structure. Two sets of clamping mechanisms 5 are installed on the inner side of the ignition chamber 11. The two sets of clamping mechanisms 5 are arranged symmetrically on the left and right. The end of the clamping mechanism 5 is fixed with a mounting base 9. A pressure wheel 8 is rotatably installed on the mounting base 9. The PLC controller 3 is electrically connected to the power supply 2 and the electronic igniter 4 respectively. The electronic igniter 4 ignites the fireworks lead wire. The ignition process takes place inside the ignition chamber 11, thereby reducing the influence of the external environment on the ignition process. The ignition chamber 11 is a transparent structure, so the insertion part of the fireworks lead wire can be observed.

[0022] The pressing mechanism 5 includes a movable rod 52 and a limiting block 53. The movable rod 52 is movably connected to the ignition chamber 11, and the limiting block 53 is fixed to the outer end of the movable rod 52. The mounting seat 9 is fixed to the inner end of the movable rod 52. The pressing mechanism 5 also includes a spring 51, which is sleeved on the movable rod 52 and is located between the mounting seat 9 and the ignition chamber 11. When the firework fuse is inserted into the ignition chamber 11 through the fuse inlet 10 and passes through two sets of pressure rollers 8, the pressure rollers 8 compress the mounting seat 9. The mounting seat 9 drives the movable rod 52 to move relative to the ignition chamber 11. At this time, the spring 51 is compressed and deformed. The deformation force of the spring 51 reacts to the mounting seat 9, thereby pressing the firework fuse with the pressure rollers 8. When the firework fuse passes through the two sets of pressure rollers 8, its end extends into the interface position of the electronic igniter 4, which can fix the firework fuse, thereby preventing the firework fuse from loosening during the ignition process and ensuring that the firework can be ignited normally.

[0023] It also includes a heat insulation layer 7, which is disposed on the surface of the pressure roller 8. The heat insulation layer 7 is a ceramic fiber reinforced polyether ether ketone layer, thereby insulating the pressure roller 8.

[0024] It also includes anti-slip strips 6, which are fixed in a rotating array on the pressure roller 8. The anti-slip strips 6 on the pressure roller 8 are staggered and located in symmetrical positions on the left and right sides. The anti-slip strips 6 further fix the firework fuse, thereby preventing it from loosening during the firing process.

[0025] The working principle of the ignition device for a fireworks display rack provided by this utility model is as follows: The fireworks fuse is inserted into the ignition chamber 11 through the fuse inlet 10 and passes through two sets of pressure rollers 8. At this time, the pressure rollers 8 squeeze the mounting base 9. The mounting base 9 drives the movable rod 52 to move relative to the ignition chamber 11. At this time, the spring 51 is compressed and deformed. The deformation force of the spring 51 reacts to the mounting base 9, thereby pressing the fireworks fuse tightly with the pressure rollers 8. When the fireworks fuse passes through the two sets of pressure rollers 8, its end extends into the interface position of the electronic igniter 4.

[0026] It is worth noting that the components disclosed in the above embodiments are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The working method of the PLC controller 3 controlling the electronic igniter 4 adopts existing technology. The electronic igniter 4 is a product currently on the market, and its structure and principle are publicly known technology. This solution only describes its role in this solution and the technical effects it is intended to produce. The PLC controller 3 adopts a three-level control architecture:

[0027] Main control unit: STM32H743 chip, supporting GPS / BeiDou dual-mode timing;

[0028] Regional repeater: LoRa wireless networking;

[0029] End effector: Semiconductor bridge ignition technology (SCB).
