Description

Technical Field

[0001] This utility model belongs to the field of fireworks manufacturing technology, and in particular relates to an improved structure fireworks device for repelling birds at airports at night. Background Technology

[0002] Bird control in airport airspace is primarily aimed at effectively preventing and protecting aircraft from being ingested into engines or struck by birds while flying in critical flight zones around airports. Traditional bird control methods include auditory intimidation, visual scare tactics, and netting, but these methods are labor-intensive, time-consuming, and generally ineffective, sometimes even posing safety hazards. Therefore, it is essential to develop and innovate a safe and environmentally friendly nighttime odor-based bird-repelling device. Utility Model Content

[0003] The purpose of this invention is to provide an improved pyrotechnic device for repelling birds at airports at night. This pyrotechnic device overcomes the shortcomings of existing technologies that use a mixture of explosive or toxic chemical odors mixed in the inner cavity of a paper tube to repel birds. It has the advantages of low-altitude launch to produce multiple effects of sound, light, and odor to repel birds from impacting or inhaling aircraft and other objects. Its assembly structure is simple, using existing cylindrical fireworks, rocket fireworks, or spherical fireworks as carriers for assembly. The odorant is safe, environmentally friendly, and harmless to humans and animals.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An improved pyrotechnic device for repelling birds at airports at night includes a bird-repelling projectile body, a rocket-shaped firework carrier component, a spherical firework carrier component, a propellant body, and an ignition fuse. The device is characterized in that: when the bird-repelling projectile body is a rocket-shaped firework carrier component, it includes a protective sleeve not located at the lower part of the projectile body, a rocket cap fitted onto the top of the projectile body, and a rocket rod for handheld ignition fixed to one outer side of the projectile body. These components are assembled to form an integrated rocket-structure bird-repelling pyrotechnic device.

[0006] In the above-mentioned technical implementation scheme, the inner cavity of the bird repellent cartridge is further arranged in layers from bottom to top, including a cartridge mud bottom, a propellant, a paper partition B with a central hole, a detonator, a paper partition A with a central hole, and a bird repellent agent, and the cartridge opening is sealed with a sealing material.

[0007] In the above-described technical implementation, further, there is no mud bottom lead wire insertion hole at the center of the mud bottom of the cylinder, and the ignition lead wire extends vertically through the mud bottom lead wire insertion hole to the outside of the lower end hole of the rocket protective sleeve.

[0008] In the above technical implementation, the bird repellent is further described as an odorant, which is either dispersed or packaged in a thin film bag.

[0009] In the above-mentioned technical implementation scheme, the bird-repelling projectile tube body or the carrier launching structure with inner and outer cylinder structure is further described as follows: the molded bird-repelling projectile tube body filled with the mud bottom of the tube body, the propellant, the detonator, the bird-repelling agent, and the ignition fuse is placed inside one or more launching outer cylinders of the combined potted flower. The ignition fuse is horizontally inserted from the mud bottom of the tube body through the side lead wire insertion hole of the tube body and extends to the outside.

[0010] In the above technical implementation scheme, the bird-repelling bullet tube body is a cylindrical paper tube structure, but it can also be a cylindrical structure made of other materials.

[0011] In the above-described technical implementation, the bird-repelling projectile can also be a spherical firework carrier component. The propellant is placed in the inner cavity of the protrusion below the lower shell of the spherical firework carrier component. When the projectile is launched, the protrusion supports the ground. The detonator is placed in the inner cavity of the lower half of the spherical firework carrier component. A partition plate is provided above the detonator in the inner cavity of the spherical firework. A bird-repelling agent packaged in a thin film bag is placed above the partition plate. The bird-repelling agent is a powdered scented agent.

[0012] Beneficial effects

[0013] The main advantages and beneficial effects of this utility model are:

[0014] 1. In the technical implementation scheme of this utility model, the bird-repelling projectile tube contains a detonating explosive agent and an odor agent, which is particularly suitable for bird repelling at airports at night. Moreover, it adopts the assembly structure of rocket fireworks or the assembly and launch structure of the inner and outer tubes of a combined flower pot. In this structure, it can be launched by a single tube or multiple tubes, or it can adopt the structure of a spherical firework shell. Thus, the assembly carrier of the bird-repelling projectile has a variety of structural shapes. It can also borrow the assembly and assembly of existing fireworks products, resulting in lower R&D costs and convenient procurement of semi-finished paper tubes.

[0015] 2. Due to the adoption of the technical solution of this utility model, its assembly structure is simple. Because it utilizes the opening powder of fireworks, it makes a loud noise after it explodes in the air. In addition, the smell is more effective at repelling birds than the simple sound of explosion. It achieves the effect of sound, light and smell, and is relatively safe. The smell has a wide range of influence in the air and the smell stays in the air for a longer time than sound and light. Attached Figure Description
