Description

Technical Field

[0001] This utility model relates to the field of bird deterrence equipment technology, and in particular to a protective device for installing an ignition rod in a bird deterrence projectile launcher. Background Technology

[0002] Bird deterrent launchers are widely used in bird control operations at major airports both domestically and internationally. By using bird deterrent launchers, airports can effectively reduce bird strikes and ensure aviation safety and smooth operations. In addition, bird deterrent launchers are also suitable for other locations requiring bird control, such as farmland and orchards.

[0003] The existing mainstream bird deterrence equipment mainly uses acoustic (such as sonic bird deterrents) or optical (such as laser bird deterrents and terror eyes) principles to deter birds. These devices are easily adapted to by birds after repeated use, so it is difficult to achieve the goal of bird deterrence by sound and optical effects alone. Moreover, these devices will bring unnecessary sound and light pollution to the airport and the surrounding environment, and may even have a certain impact on operators and nearby residents.

[0004] Some airports have begun using solid projectiles to scare away birds. Two-stage firecrackers and titanium-plated firecrackers are two of the most commonly used bird-scare projectiles. They generally employ a two-stage gunpowder ignition process. Direct ignition achieves the first stage of explosive propulsion, propelling the projectile towards the bird. The second stage of explosion occurs in mid-air near the bird, producing a multi-sensory effect including sound, flash, and shockwave. Years of practical application have shown that this type of bird-scare projectile is currently the most effective, efficient, and least adaptable method for bird control.

[0005] Bird deterrent projectile combustion can be divided into two stages: the launch stage and the explosion stage. In the launch stage, a fuse ignites the propellant, and the combustion of the propellant generates an airflow that propels the projectile into the air. In the explosion stage, the propellant ignites the fuse between itself and the explosive propellant, which in turn ignites the explosive propellant, causing the projectile to explode. The structure of a bird deterrent projectile typically includes the following main parts: the cartridge case, the propellant, the payload (such as a sound device, flash device, or object), and the fuse. Some fuses use an ignition rod to ignite the propellant inside the cartridge case; however, improper installation of an ignition rod can easily lead to the ignition rod needle breaking due to the impact generated during the explosion.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a protective device for the ignition rod of a bird deterrent projectile launcher, thereby overcoming the disadvantage that the ignition rod needle is prone to breakage when igniting the bird deterrent projectile.

[0008] To achieve the above objectives, this utility model provides a protective device for mounting the ignition rod of a bird-repelling projectile launcher. The bird-repelling projectile launcher includes a gun mount, multiple gun barrels, and an ignition device. The multiple gun barrels are mounted on the gun mount, and each gun barrel corresponds to one of the ignition devices. Each ignition device includes an ignition rod, which is mounted on the protective device. The protective device includes a U-shaped mounting plate, which comprises an upper mounting plate and a lower mounting plate. The upper mounting plate has a through hole on its surface, corresponding to the upper through hole. The lower surface of the upper mounting plate is provided with a hollow cylinder. The lower mounting plate is provided with a through lower hole. The through lower hole, the upper through hole, and the cylinder are on the same vertical line. The lower mounting plate is provided on the gun carriage and is located close to the gun barrel. The lower end of the ignition rod passes through the through lower hole of the lower mounting plate, and the upper end is provided with an ignition rod needle, which extends into the cylinder. The upper end is placed in the upper through hole of the upper mounting plate. The shell fuse in the gun barrel should be placed in the upper through hole of the upper mounting plate and be in contact with the ignition rod needle.

[0009] Preferably, in the above technical solution, the mounting plate has an asymmetrical U-shaped structure, and the lower mounting plate is longer than the upper mounting plate.

[0010] Preferably, in the above technical solution, the upper mounting plate and the lower mounting plate are integrally formed.

[0011] Preferably, in the above technical solution, the upper through hole of the upper mounting plate is a through hole formed by two partially overlapping circles.

[0012] Preferably, in the above technical solution, the upper through hole of the upper mounting plate is an elongated hole.

[0013] Preferably, in the above technical solution, the lower through hole of the lower mounting plate is an elongated hole.

[0014] Preferably, in the above technical solution, the lower mounting plate is provided with mounting holes, the mounting holes are elongated holes, and the mounting holes and the lower through holes are on the same center line.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This utility model relates to a protective device for mounting the ignition rod of a bird-repelling projectile launcher, used for mounting the ignition device of the bird-repelling projectile. The protective device includes a U-shaped mounting plate, an upper mounting plate with a through hole, a hollow cylinder for protection on the lower surface, and a lower mounting plate with a through hole. During installation, the lower mounting plate is fixed to the gun mount, the ignition rod passes through the lower hole, and the ignition rod needle at the upper end extends into the through hole of the upper mounting plate. The fuse of the projectile is also placed in the through hole. During ignition, the fuse is heated and ignited by the ignition rod needle. Since there is a cylinder below the through hole, most of the ignition rod needle is placed inside or below the cylinder, with a small part of the upper end extending into the through hole. Therefore, the impact of the explosion of the ignition projectile on the ignition rod needle is reduced, preventing the ignition rod needle from breaking.

[0017] (2) The present invention is used for the ignition rod installation protection device for bird deterrent projectile launcher. The lower through hole and the mounting hole of the lower mounting plate are both elongated holes, which facilitates the adjustment of the position of the ignition rod needle in the upper through hole of the upper mounting plate, so that the ignition rod needle fits with the projectile fuse, improves the accuracy of ignition, and achieves a 100% ignition rate.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] like Figures 1 to 4 As shown, according to a specific embodiment of the present invention, an ignition rod mounting and protective device for a bird deterrent projectile launcher is provided. The bird deterrent projectile launcher includes a gun mount 1, multiple gun barrels 2, and an ignition device 3. The middle and rear sections of the multiple gun barrels 2 are spaced apart from each other and parallel to each other on the gun mount 1, and the front ends extend outward from the gun mount 1. Each gun barrel 2 is connected to the ignition device 3, and the ignition device 3 is connected to the rear end of the gun barrel 2. The ammunition inside the gun barrel 2 is ignited by the ignition device 3, and the projectile is launched through the front end of the gun barrel 3.

[0027] The ignition device 3 includes an ignition rod 31, with an electric wire at its lower end for connecting to a power source to heat the ignition rod. An ignition rod needle 32 is located at the upper end of the ignition rod 31, which is mounted on the protective device 4. The protective device 4 includes a U-shaped mounting plate, comprising an upper mounting plate 41 and a lower mounting plate 42, which are integrally formed. The upper mounting plate 41 has a through-hole 43, and a hollow cylinder 44 is located on the lower surface of the upper mounting plate 41 directly below the through-hole 43, with the cavity of the cylinder 44 penetrating both the upper and lower surfaces. The lower mounting plate 41 is located within a through-hole 45, which is aligned vertically with the upper through-hole 43 and the cylinder 44. The lower mounting plate 42 is mounted on the gun carriage 1 and positioned close to the gun barrel 2.

[0028] With the ignition rod in the installed state, the lower end of the ignition rod 31 passes through the lower through hole 45 of the lower mounting plate 42, and the upper ignition rod needle 32 extends into the cavity of the cylinder 44, extending beyond the upper end of the cylinder 44 and into the upper through hole 43 of the upper mounting plate 42. The shell fuse 21 loaded in the barrel 2 should be placed in the upper through hole 43 of the upper mounting plate, fitting snugly against the ignition rod needle 32. During ignition, the ignition rod 31 is energized and heated, and the heat is conducted to the ignition rod needle 32. The shell fuse contacts the ignition rod needle 32, and when the ignition rod is heated, the fuse ignites, igniting and firing the shell. At the same time, because there is a cylinder 44 below the upper through hole, most of the ignition rod needle is placed inside or below the cylinder, with only a small part of the upper end extending into the upper through hole. Therefore, the impact force of the shell explosion on the ignition rod needle is reduced, preventing the ignition rod needle from breaking.

[0029] Preferably, the mounting plate has an asymmetrical U-shaped structure, with the lower mounting plate 42 being longer than the upper mounting plate 41. The longer lower mounting plate 42 facilitates installation on the gun mount 1.

[0030] Preferably, the upper through hole 43 of the upper mounting plate 42 is a through hole formed by two partially overlapping circles. That is, the upper through hole is an elongated hole formed by two semicircles, one semicircle is used to place the ignition rod needle 32, and the other semicircle is used to place the shell fuse.

[0031] Preferably, the upper through hole 43 of the upper mounting plate is an elongated hole. The lower through hole 45 of the lower mounting plate is an elongated hole. The lower mounting plate is provided with a mounting hole 46, which is an elongated hole, and the mounting hole 46 and the lower through hole 45 are on the same center line. The fact that both the lower through hole 45 and the mounting hole 46 of the lower mounting plate are elongated holes facilitates the adjustment of the position of the ignition rod needle in the upper through hole of the upper mounting plate, thereby improving the accuracy of ignition.

[0032] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
