Description

Technical Field

[0001] This invention relates to an environmentally friendly bird deterrent projectile device with an electromagnetic conductive ignition head structure, mainly used for bird deterrence in airport flight zones, and belongs to the technical field of bird deterrence devices / equipment. Background Technology

[0002] Bird control refers to all measures taken by military and civilian airports to ensure the safety of aircraft takeoff and landing, preventing birds from being sucked into aircraft engines or colliding with the fuselage, landing gear, tail, windshield, and other parts of the aircraft during takeoff and landing. These measures include auditory intimidation, visual deterrence, direct capture, chemical, ecological, or radar warnings. Although birds are small and slow, aircraft travel at high speeds. When birds and aircraft fly towards each other, the relative speed between them is significant. Data shows that a bird weighing 1.8 kg colliding with an aircraft traveling at 550 km / h will generate an impact force of 25 tons, equivalent to being hit by a cannonball. The force of a single bird is enough to destroy an aircraft. Bird strikes not only cause enormous loss and harm to passenger lives and property but also result in many indirect economic losses such as flight delays. After all, the safety of passengers is paramount. Bird strikes are classified as a Class A air hazard by the International Civil Aviation Organization (ICAO). Therefore, bird control in airport flight areas has become a crucial task.

[0003] To effectively prevent bird strikes and better ensure aviation safety, and considering the frequent activity of birds in the airspace surrounding airports, the applicant of this invention, in order to complement the production and application of new bird deterrent launchers for general aviation, has conducted extensive research and innovation on the bird deterrent projectile device used in bird deterrent launchers through years of continuous trial and practice. In particular, current bird deterrent projectiles have many problems, such as: some projectiles use a fuse / ignition wire to ignite and conduct the ignition to the explosive charge, but this method has drawbacks: the installation and connection of the fuse / ignition wire is cumbersome, requiring professional personnel for installation, which is not conducive to the continuous launch and explosion of bird deterrent projectiles in a short period of time; moreover, the fuse / ignition wire is prone to moisture damage and ignition failure, and sometimes, if not installed properly, it is easy to break, seriously affecting ignition, combustion, and launch, and resulting in poor timeliness and low launch and explosion rates.

[0004] Currently, many airports use solid cannonballs for bird deterrence. The inner tube of the cannonball is made of paper and is launched into the air along with the bird deterrence explosive. After the explosion, there are still pieces of paper left behind. In addition, the explosive is not completely detonated. The small lumps or granules of solidifying agent, yellow mud, paper and other concretions left in the airspace are about 1 square centimeter in size, which greatly affects flight safety. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this invention is to provide an environmentally friendly bird-repelling projectile device with an electromagnetic conductive ignition head structure. This bird-repelling projectile device is a tubular projectile casing with a closed bottom. At the moment of the ejection of the flame, the bird-repelling projectile body is ignited by a three-stage ignition system, causing it to explode in the air. The ignition is rapid, safe, reliable, and stable. It can directly connect the modified new type of electric ignition head with a wireless electromagnetic induction conductive block, and ignite the two poles at the end of the conductive electric ignition head to eject the flame, which then ignites the bird-repelling propellant body and causes it to explode. After the propellant body explodes, there are no residues in the airspace or on the ground. Multiple projectiles can be fired continuously to repel birds.

[0006] To achieve the above objectives, the present invention can be implemented through the following technical solutions.

[0007] An environmentally friendly bird-repelling projectile device with an electromagnetic conductive ignition head structure is mainly used for bird control in airport flight areas. It includes a projectile casing body, characterized by: an electromagnetic conductive ignition head assembly unit, an ignition head inner liner unit, a bird-repelling projectile body unit, at least one flame ejection hole placed on the end panel of the ignition head inner liner unit, and a propellant layer bonded to the end panel of the ignition head inner liner unit, all sequentially arranged at the bottom of the inner cavity of the projectile casing body; the launch port of the projectile casing body is sealed by a sealing end cap; the bird-repelling projectile device, composed of the above components, is used in conjunction with an aviation-specific bird-repelling launcher for firing.

[0008] Furthermore, in the implementation of the above technical solution, the electromagnetic conductive ignition head assembly unit also includes a radio electromagnetic induction circuit magnetic block, a radio electromagnetic induction circuit coil disposed on the radio electromagnetic induction circuit magnetic block, and an electric ignition component structure fixedly connected to the two electrodes at the center of the electromagnetic induction conductive circuit magnetic plate.

[0009] Furthermore, in the implementation of the above technical solution, the bird-repelling ammunition body unit also includes a bird-repelling explosive body, a central explosive cavity, an explosive charge, an explosive sealing layer, and a moisture-proof wrapping layer for the explosive body. The shape of the central explosive cavity is a matching geometric structure, such as a conical opening structure, a cylindrical opening structure, or a polygonal opening structure.

[0010] Furthermore, in the implementation of the above technical solution, the electric ignition assembly structure also includes a conductive stake structure, two-pole ignition wires, two-pole discharge end structures, and an ignition head. The conductive stake structure is a long, cylindrical structure, and the two-pole discharge end is an inwardly curved, elbow-shaped structure. The ignition head is completely wrapped around the upper part of the conductive stake structure and the outside of the two-pole discharge end. In use, when the lower radio electromagnetic induction circuit coil conducts electricity through the contact point between the positive and negative poles at the center of the coil and the bottom end of the two-pole ignition wire to the two-pole discharge end structure at the top of the two-pole ignition wire, a high-voltage pulse discharge is used to break down the dielectric between the two-pole discharge end structures, generating a spark arc that forms a high-temperature ignition charge between the two-pole discharge end structures, thereby igniting the propellant in the ignition head.

[0011] Furthermore, in the implementation of the above technical solution, the inner bushing unit of the electric ignition head is constructed using an anti-static injection molded part, which is cylindrical in shape. At the bottom center of the inner bushing unit of the electric ignition head, below the flame jet hole on its top panel, there is an electric ignition component inlet hole for the electric ignition component structure to pass through and connect. Multiple bushing chambers are also evenly arranged around the electric ignition component inlet hole.

[0012] Furthermore, in the implementation of the above technical solution, the electric ignition component is a spark-type electric ignition head structure or a drug-free safety electric ignition head structure.

[0013] Furthermore, in the implementation of the above technical solution, the wireless electromagnetic induction circuit coil is constructed using a PCB coil structure.

[0014] Furthermore, in the implementation of the above technical solution, the launch cartridge body is a tubular structure with one open end, formed by injection molding of rigid plastic material.

[0015] This invention also provides another technical embodiment of an environmentally friendly bird-repelling projectile device with an electromagnetic conductive ignition head structure. Its features include: a projectile casing body, an electromagnetic conductive ignition head assembly unit connected above the bottom surface of the inner cavity of the projectile casing body, a propellant layer bonded and fixedly connected to the lower panel of the electromagnetic conductive ignition head assembly unit, and a bird-repelling ammunition body unit movably connected to the upper inner cavity of the projectile casing body and connected to the top contact point of the electromagnetic conductive ignition head assembly unit. The firing port end of the projectile casing body is sealed by a sealing end cap. The above components are combined into an integrated bird-repelling projectile device. The interval cavity formed between the electromagnetic conductive ignition head assembly unit and the bottom of the bird-repelling ammunition body unit enables the electromagnetic conductive ignition head assembly unit to ignite the propellant layer and the large amount of heat energy generated by the combustion at the bottom of the bird-repelling ammunition body unit simultaneously through electromagnetic induction heat / electricity conduction. This amplifies the pressure within the sealed cavity, directly propelling the bird-repelling ammunition body unit into the air, simplifying the processing technology and assembly steps, and achieving a better bird-repelling effect.

[0016] Furthermore, in another embodiment of the present invention, the electromagnetic conductive ignition head assembly unit includes a radio electromagnetic induction circuit magnetic block, a radio electromagnetic induction circuit coil, two conductive terminals, an electric ignition component structure, and a propellant layer. The two conductive terminals are connected at the center of the radio electromagnetic induction circuit coil. The electric ignition component structure is fixedly connected perpendicularly above the two conductive terminals. The propellant layer is bonded to the top of the radio electromagnetic induction circuit magnetic block. The radio electromagnetic induction circuit magnetic block has a copper-clad laminate structure, and the radio electromagnetic induction circuit coil has a PCB coil configuration.

[0017] Furthermore, in another embodiment of the present invention, the copper-clad laminate structure on the magnetic block of the radio electromagnetic induction circuit is an ultra-thin single-sided copper-clad laminate structure, on which the required PVB structure coil is printed.

[0018] Beneficial effects

[0019] The significant advantages and beneficial effects of this invention compared to the prior art are as follows:

[0020] 1. The electromagnetic conductive ignition head assembly structure of the present invention improves the existing ignition head structure by directly connecting the conductive stake to the two electrodes at the center of the electromagnetic induction circuit magnetic plate to form an integral structure. The ignition head conducts electricity and ignites quickly, with stable and reliable conductivity, and the explosive body has a 100% ignition rate. This effectively solves the problem of the existing technology where the connection between the physical explosive bomb and the radio electromagnetic induction conductive part is not firm and the ignition is easy to break midway.

[0021] 2. Due to the structure of the electromagnetic induction conductive ignition head assembly, it adopts the existing wireless electromagnetic induction conductive principle, which overcomes the shortcomings of solid explosive bird deterrent projectiles, which require an open flame or electric ignition to ignite the fuse and then burn the solid explosive projectile through the fuse. The process takes a long time, has poor timeliness, and has low efficiency in launching explosive bird deterrents.

[0022] 3. In one embodiment, due to the adoption of the technical solution of the present invention, the bird-repelling explosive body is constructed using environmentally friendly fireworks materials currently used in the fireworks industry, which are formed by one-time molding. The inner cavity of the explosive body has a space area that can be filled with a large capacity of explosive material. This space area can be configured as a trapezoidal cone structure, or a cylindrical structure, or a trapezoidal square pyramid structure, or a square prism structure. In addition, it can be configured as other suitable geometric shapes. However, the inner cavity space area must be the largest possible, capable of maximizing the capacity of the explosive material to maximize its explosive force. The opening of the constructed inner cavity space area faces upwards towards the explosive body, allowing the explosive body to burn completely and explode without leaving any residue. When assembling the explosive charge, after the explosive charge is loaded into the central space of the explosive charge, the open end of the top of the charge is sealed with a moisture-proof adhesive layer. Bird deterrent ammunition units with this structure ignite and explode instantly after launch. Compared with solid ammunition in the prior art, the explosive charge unit has increased charge, increased strength, and correspondingly increased explosion pressure, resulting in a louder and more powerful explosion sound. There are no residues in the air or on the ground within the flight area of ​​the explosion, truly achieving an explosion of the explosive charge without any residue, which meets the safety and environmental protection requirements of the flight area.

[0023] 4. In a further embodiment, in order to improve the moisture-proof and protective performance of the bird-repellent explosive body, make the explosive structure stable and not prone to failure, and have a high safety factor, a moisture-proof coating layer is wrapped around the periphery and upper surface of the cylindrical part of the formed bird-repellent explosive body. In this way, the outer explosive layer of the formed bird-repellent explosive body unit will not be damaged when it is boxed, stored, transported and filled into the inner cavity of the launcher shell.

[0024] 5. In one embodiment, the addition of an inner bushing unit for the electric ignition head and a combined unit for the electromagnetic conductive electric ignition head not only ensures the electric ignition component structure in the combined unit is fixedly aligned and does not deviate from the flame jet hole above the bushing, thus protecting and fixing the entire combined unit, but also serves as a carrier for the adhesion and bonding of the propellant layer. This solves the problem of the existing propellant carrier structure, more effectively ignites the bird-repelling explosive projectile instantly, and effectively solves the problem of the paper tube of the projectile and the bird-repelling explosive projectile exploding together in the air, achieving no paper scraps or other debris left in the flight airspace.

[0025] 6. In another embodiment, the bird-repelling projectile device can be further improved and innovated. The main innovation lies in further simplifying the internal structure of the projectile casing body of the bird-repelling projectile device. The electric ignition head inner bushing unit is removed, and the propellant layer structure originally bonded to the top surface of the electric ignition head inner bushing unit is placed on the radio electromagnetic induction circuit magnetic block at the lower end of the electromagnetic conductive electric ignition head assembly unit. The radio electromagnetic induction circuit coil is fully covered and tightly bonded. In this structure, an interval cavity is formed between the electromagnetic conductive electric ignition head assembly unit and the continuously mounted bird-repelling projectile body unit. After the propellant layer on the electromagnetic conductive electric ignition head assembly unit is ignited by heat conduction, the large amount of heat generated by the combustion of the propellant increases the pressure in the sealed cavity. This can directly push the bird-repelling projectile body unit into the air, resulting in greater launch thrust and an altitude more than 30 meters higher than the previous structure of the bird-repelling projectile device. More importantly, the internal structure of the bird-repelling projectile device is simpler, the assembly process is simpler, the heat pressure of the burning propellant is stronger and greater, the launch altitude is higher, and the bird-repelling effect is better.

[0036] It should be specifically noted that numerous specific details are presented in the following description to provide a thorough understanding of this invention. However, it will be apparent to those skilled in the art that the invention can be implemented without using some or all of these specific details. It should be understood that the embodiments described in this application are only a portion of the embodiments of the invention, not all of them. All other different embodiments implemented based on a preferred embodiment of this application, without inventive effort by those skilled in the art, should fall within the protection scope of this application.

[0037] As shown in the figure, the present invention is composed of the following components / assemblies: a projectile casing body 1, an electromagnetic conductive ignition head assembly unit 2, an ignition head inner bushing unit 3, a flame jet hole 4, a propellant layer 5, a bird-repellent ammunition body unit 6, a sealing end cap 7, a radio electromagnetic induction circuit magnetic block 201, a radio electromagnetic induction circuit coil 202, an electric ignition assembly structure 203, a coil induction end face 204, a two-pole conductive end 205, an explosive body moisture-proof wrapping layer 601, an explosive opening sealing adhesive layer 602, an explosive opening 603, an explosive opening cavity in the center of the propellant body 604, a bird-repellent ammunition explosive body 605, a conductive stake structure 2031, a two-pole ignition wire 2032, a two-pole discharge end structure 2033, an ignition head 2034, an electric ignition assembly inlet hole 301, and a bushing chamber 302.

[0038] In addition, it should be noted that the wireless electromagnetic induction circuit magnetic block, electric ignition head, detonator and explosive used in this invention are all products of known technology and are available on the market. However, this invention has made further improvements and innovations to the structure of some known components, changed the non-contact ignition in the prior art, changed the way the firing cartridge case and the explosive body are launched into the air and explode together, and changed the paper structure of the firing cartridge case. It is constructed into a completely new device structure that only fires bird deterrent ammunition into the air, so as to adapt to the use of existing bird deterrent launchers / guns for general aviation. Example

[0039] The structural features of the specific embodiment are as follows:

[0040] As shown in the figure, the present invention provides an environmentally friendly bird deterrent projectile device with an electromagnetic conductive ignition head structure, mainly used for bird deterrence in airport flight areas. It includes a projectile casing body 1, and its special feature is that it also includes an electromagnetic conductive ignition head assembly unit 2, an ignition head inner liner unit 3, a bird deterrent projectile body unit 6, at least one flame jet hole 4 located at the center of the top surface of the ignition head inner liner unit, and a propellant layer 5 bonded to the top surface of the ignition head inner liner unit. The launch port end of the projectile casing body is sealed by a sealing end cap 7. The bird deterrent projectile device, which is composed of the above components into an integrated structure, is used in conjunction with an aviation-specific bird deterrent launcher for electromagnetic induction ignition and launch.

[0041] Furthermore, in one embodiment, as shown in the figure, the specific assembly process in this invention is: [The process involves]... Figure 1Components 1, 2, 3, 4, 5, 6, and 7 are individually processed / assembled according to specifications and technical requirements. The launch cartridge case body 1 has an open upper end. When assembling the electromagnetic conductive ignition head assembly unit 2, the insulation layer of the ends of the two pole ignition wires 2032 at the lower end of the electric ignition component structure 203 is removed, and they are vertically welded to the positive and negative conductive ends 205 at the center of the upper and lower surfaces of the lower radio electromagnetic induction circuit magnetic block 201 onto the circular sheet circuit magnetic block. Multiple flame jet holes 4 are machined in a plum blossom pattern on the top surface of the electric ignition component inlet hole 301 corresponding to the center of the injection-molded component electric ignition head inner bushing unit 3. At least four bushing chambers 302 are evenly arranged and machined in the electric ignition component inlet hole 301. The arrangement of these bushing chambers allows the electromagnetic conductive ignition head inner bushing unit 3 to be fitted with the electromagnetic conductive ignition head assembly. The ignition assembly unit reduces air resistance and stores air to provide oxygen supplementation for the combustion of the ignition head 2034 on the electric ignition head assembly structure 203. A layer of existing fireworks propellant 5 is glued to the upper surface after processing and molding. The propellant can be military-grade gunpowder or environmentally friendly smokeless propellant. The bird deterrent projectile unit 6 adopts a built-in trapezoidal cone processing configuration structure. Sufficient explosive 603 is filled into the explosive cavity 604 in the center of the explosive body of the trapezoidal cone. The opening is sealed with an explosive sealing layer 602. Then, the explosive body moisture-proof wrapping layer 601 made of moisture-proof kraft paper tightly glues and connects the circumferential surface and the upper surface of the explosive body. The sealing end cap 7 is made of hard plastic material or ordinary plastic material injection molding or plastic sheet processing and matches the opening end of the launching shell body 1. During assembly, the launch cartridge case body 1 is placed with its opening facing upwards. First, the electromagnetic conductive ignition head assembly unit 2 is lowered and placed on the bottom of the inner cavity of the launch cartridge case body. Then, the electric ignition head inner liner unit 3, with the propellant layer 5 bonded to it, is lowered and fitted onto the electric ignition assembly structure 203 above the radio electromagnetic induction circuit magnetic block 201 of the electromagnetic conductive ignition head assembly unit 2, so that the electric ignition assembly structure 203 is precisely inserted into the electric ignition assembly inlet hole 301 in the center, and the ignition head 2034 is aligned with the propellant. The nozzles are aligned; then the bird-repellent ammunition body unit 6 is installed. The bird-repellent ammunition body unit 6 is filled above the inner liner unit 3 of the electric ignition head, so that the bottom surface of the bird-repellent ammunition explosive body 605, which is not wrapped with the moisture-proof wrapping layer 601 of the explosive body, is tightly attached to the propellant layer 5 on the inner liner unit 3 of the electric ignition head and falls into place. Finally, the opening at the upper end of the launcher case body is fixed and sealed with adhesive using the sealing end cap 7. This completes the assembly and molding of the environmentally friendly bird-repellent ammunition device with the entire electromagnetic conductive electric ignition head structure into a product.

[0042] In use, it can be assembled and launched in conjunction with existing aviation bird deterrent launchers or other matching launching devices. Specifically, the molded product of this invention is inserted into the magazine or loading device of the launching device. When firing, the trigger connects to the bottom of the bird deterrent projectile's cartridge case and is connected to the power supply in the launcher. At this time, the electromagnetic induction conductive ignition head assembly unit in the bird deterrent projectile device, through the principle of radio electromagnetic induction, conducts electrical energy from the stored power supply in the electromagnetic induction launcher to the two conductive terminals at the center of the electromagnetic induction coil, converting the energy to the connected... In the electric ignition assembly, when the two-pole ignition wire conducts electricity through the two-pole conductive ends, the two-pole discharge end structure at the ends releases electrical energy, generating a spark that ignites the propellant head. The flame is then ejected upwards from the flame injection hole, igniting the propellant layer adhered to the top surface of the inner bushing unit of the electric ignition head. This instantaneous combustion ignites the bird-repelling explosive at the bottom of the bird-repelling ammunition body unit. Simultaneously, the heat generated by the propellant layer's deflagration within the sealed tube intensifies, propelling the bird-repelling explosive out of the launch tube and into the flight area. The detonation of the bird-repelling explosive further drives away birds within the flight area, ensuring flight safety and providing an environmentally friendly, smokeless, odorless, and residue-free process. Because the wireless electromagnetic induction magnetic sheet is existing technology, its working principle and the specific workflow of electromagnetic induction and conductivity conversion are not described in detail in this invention application.

[0043] In one implementation, such as Figure 7 As shown, specifically, the launcher casing 1 is constructed with a closed bottom and an open top, and the launcher casing is made of anti-static, rigid plastic material through injection molding. The bird-repellent explosive 605 is processed and pressed into a cylindrical shape with a central open explosive cavity. The central open explosive cavity 604 of the explosive 605 is pressed into a lower conical or lower conical trapezoidal structure. When the processed explosive 605 is ignited, it starts burning from the bottom of the bird-repellent explosive 605, which is then conducted to the lower conical trapezoidal end of the central open explosive 603 and rapidly burns upwards in the open explosive cavity, instantly detonating the bird-repellent explosive 605. Due to the sufficient amount of explosive, the explosive 605 explodes in the air without leaving any residue.

[0044] Furthermore, the structure of the explosive chamber 604 at the center of the bird-repellent ammunition body unit 6 of this invention, in conjunction with the explosive sealing layer 602 on the open end face, provides a fully enclosed space for the explosive 603. The explosion principle is as follows: when the explosive 603 at the bottom of the lower cone is ignited by the bird-repellent explosive body 605, it can rapidly burn in the enclosed space to the upper part of the enclosed space, releasing a large amount of heat energy and generating high-temperature and high-pressure gas. This allows the bird-repellent explosive body 605 to explode instantly after being launched from the launch case body 1 into the flight airspace, producing a sound. Under the condition of rapidly increasing explosion heat energy pressure, the decibel of the explosion sound is further increased and enhanced, causing the compacted explosive body to burn into tiny dust particles that scatter in the airspace without any residue. This provides reliable protection for the safe flight of aircraft in the flight airspace, is more in line with environmental protection requirements, has a high explosion safety factor, and a good bird-repelling effect.

[0045] See Figure 7 As shown, the bird-repellent explosive body 605 is constructed according to the pyrotechnic compression molding method in the prior art. The difference between it and the existing drugs is that its pyrotechnics uses a smokeless and odorless environmentally friendly smokeless cellulose drug, so that the bird-repellent explosive body 605 is smokeless and odorless after detonation in the airspace during launch.

[0046] In one exemplary embodiment of the present invention, further, as shown... Figure 2 As shown, the electromagnetic conductive ignition head assembly unit 2 described in this application also includes a radio electromagnetic induction circuit magnetic block 201, a radio electromagnetic induction circuit coil 202 disposed on the radio electromagnetic induction circuit magnetic block, and an electric ignition component structure 203 fixedly connected to the two conductive ends 205 at the center of the radio electromagnetic induction circuit magnetic block.

[0047] In one exemplary embodiment of the present invention, further, as shown... Figure 7 As shown, the bird-repelling ammunition body unit 6 described in this application also includes a bird-repelling explosive body 605, a central explosive cavity 604, an explosive charge 603, an explosive charge sealing layer 602, and an explosive body moisture-proof wrapping layer 601. The shape of the central explosive cavity is any shape structure that is compatible with it, such as a conical opening structure, a cylindrical opening structure, or a polygonal opening structure.

[0048] In one exemplary embodiment of the present invention, such as Figure 3As shown, it should be specifically noted that the electric ignition assembly structure 203 described in this application also includes a conductive stake structure 2031, a two-pole ignition wire 2032, a two-pole discharge end structure 2033, and an ignition head 2034. The conductive stake structure is processed into a long strip-shaped column structure, and the two-pole discharge end is a bent head structure with an inward bending structure. The ignition head is completely wrapped around the upper part of the conductive stake structure and the outside of the two-pole discharge end. In use, when the lower radio electromagnetic induction circuit coil 202 conducts electricity through the contact point between the positive and negative poles of the coil center and the bottom end of the two-pole ignition wire 2032 to the two-pole discharge end structure 2033 at the top of the two-pole ignition wire, the high-voltage pulse discharge causes the dielectric between the two-pole discharge end structures to break down, generating a spark arc that forms a high temperature to ignite the ignition powder between the two-pole discharge end structures, thereby igniting the gunpowder in the ignition head 2034.

[0049] Furthermore, such as Figure 2 , Figure 4 , Figure 5 As shown, the wireless electromagnetic induction circuit magnetic block 201 of the present invention adopts an upper and lower sandwich copper-clad laminate structure. The copper-clad laminate is a single-sided copper-clad laminate. A wireless electromagnetic induction circuit coil 202 is printed in a ring on the panel facing upward on the single-sided copper-clad laminate, so that the two conductive ends 205 are electrically connected to the center of the wireless electromagnetic induction circuit coil.

[0050] For the magnetic block in the wireless electromagnetic induction circuit, a further optimization using copper material lies in the fact that the electromagnetic medium carrier is made of copper sheet material. This is mainly achieved by utilizing the electromagnetic principle to induce and store electrical energy within the circular copper sheet. The electrical conductivity / thermal conductivity allows the electric ignition head assembly to conduct electricity or heat to ignite the ignition head 2034. According to relevant literature from Baidu, copper is a metallic element and also a transition element. Copper is a relatively inert heavy metal that does not combine with oxygen in dry air at room temperature. Copper is also one of the earliest metals discovered and used by humans; pure copper is a soft metal. Copper is a chemical element with the chemical symbol Cu and atomic number 29. Copper is a copper-colored metal with diamagnetism and a density of 8.92 g / cm³. Its melting point is 1083.4℃, boiling point is 2567℃, solid density is 8.960 g / cm³, and ionization energy is 7.726 eV. Slightly hard, extremely tough, and wear-resistant, copper possesses good ductility, high electrical and thermal conductivity, and excellent processing properties. Therefore, it is the most commonly used material in electrical and electronic components. Copper has relatively low reactivity. Compared to aluminum, copper has a higher density and more free electrons per unit volume, resulting in superior electrical conductivity compared to metals other than silver. Pure copper has a conductivity of 54,142,857 S / m and a resistivity of 1.75 × 10⁻⁸ Ω·m. Furthermore, copper is a durable metal that can be recycled multiple times without loss of mechanical properties. Electrical conductivity, a concept in physics, is the product of the quantity and the electric field strength E in a medium, equal to the conduction current density J. In this application, copper is selected as the material to process the electric generator head assembly 2 to obtain the two-pole conductive post 201. At the same time, an existing ultra-thin copper-clad laminate is selected as the electromagnetic induction conductor component 1 with a circular sheet structure. This allows for the electromagnetic induction end face to conduct electricity with the largest area, so that the electron flow passing through the component moves towards the two-pole conductive end 106. Based on the advantages of copper's high purity, few material defects, and good appearance, it is widely used in the processing and manufacturing of various electronic components.

[0051] It should be further explained that copper clad laminate, also known as substrate or copper-clad board, is a sheet material made by impregnating reinforcing material in resin, covering one or both sides with copper foil, and then hot-pressing it. Copper clad laminate is the basic material of PCB and is usually referred to as substrate. When used in the production of multilayer boards, it is also referred to as core. Copper clad laminate is a basic material in industry and is mainly used in printed circuit boards. It is widely used in products such as televisions, radios, computers, and mobile communications.

[0052] Furthermore, Figure 2 , Figure 3This application illustrates a preferred embodiment of the present invention. The electromagnetic conductive ignition head assembly unit 2 proposed in this application uses a closed-loop circuit structure with a circular ring-shaped magnetic block 201, as described in the prior art. However, unlike the prior art, the magnetic block 201 is organically integrated with the existing wireless ignition head to form a single closed-loop wireless conductive ignition head structure. This structural feature is completely different from the dual-stage explosion-type ignition method in the prior art, and also different from the non-contact instantaneous ignition and fuse-ignition method implemented in the existing patented technologies. This application uses an electric ignition assembly structure 203, which is welded and fixedly connected to the two conductive ends 205 at the center of the magnetic block 201 perpendicular to the circular ring-shaped structure, to ignite and guide the bird-repellent ammunition body unit 6. In this embodiment, the electric ignition assembly structure 203... 03 can be constructed using the existing spark-type electric ignition head structure. This electric ignition head structure utilizes its high-voltage pulse discharge principle to generate a spark arc to form a high-temperature ignition head 2034. Then, the flame passing through multiple flame injection holes 4 on the top panel of the inner bushing unit 3 of the electric ignition head ignites the propellant layer 5. The propellant layer is glued to the top plate of the inner bushing unit of the electric ignition head. After the propellant layer 5 ignites and burns, the high temperature and high pressure conduction propels the bird-repelling ammunition body unit 6, which is set above the propellant layer, out of the sealing end cap 7 at the mouth of the launch cartridge body 1. It is launched towards the airspace where birds are active, and the heat energy generated by the combustion of the explosive 603 detonates the bird-repelling explosive body 605 wrapped around it. The explosive body explodes instantly and radiates outwards in four directions, producing a loud bird-repelling sound, thus achieving the purpose of effectively driving away birds. There is no explosive residue in the airspace.

[0053] It should be further explained that the electric ignition assembly structure 203 can also adopt an ignition method using a non-explosive electric ignition head (structure not shown) or an ordinary electric ignition head (structure not shown). The electric ignition assembly structure 203 of this invention is integrated with the radio electromagnetic induction circuit magnetic block 201 into a single structural unit, achieving convenient and quick installation, stable conductive ignition, and eliminating the need to connect a fuse or detonator between the circuit magnetic plate and the bird-repelling explosive. It boasts a 100% ignition rate and perfects direct contact instantaneous ignition. The lower ends of the two-pole ignition wires 2032 in the electric ignition assembly structure are welded to the two-pole conductive ends 205 of the circuit magnetic plate via welding points, resulting in a more robust and reliable connection, ensuring stable ignition and power supply, and facilitating use in conjunction with aircraft... The dedicated bird deterrent launcher, when used with an installed and connected energy storage device, ignites and launches via electromagnetic induction. Simultaneously, by eliminating the fuse and igniting the propellant, the abnormal discharge at the two poles of the propellant head is not affected by pressure relief discharge. In particular, by bending the two-pole discharge end structure 2033 inwards into a bent shape or using a heating wire connecting two copper plates, the discharge arc distance between the two poles is reduced, lowering the ignition voltage and the energy required for ignition. It is safe and reliable, requiring only 5W of power, and its combined device can be reused multiple times, or it can be launched in rapid succession for an aerial explosion.

[0054] It should be noted that for spark-type electric ignition head structures, such as in a preferred embodiment, such as Figure 3 As shown, the elongated column of the conductive pile structure 2031 and the magnetic block 201 of the radio electromagnetic induction circuit are integrated into a single structure, or can be any other compatible structure of any shape. The elongated column of the conductive pile structure 2031 is an injection-molded part.

[0055] The injection-molded part of the conductive stake structure 2031 is injection-molded in one piece at an appropriate length to the two-pole ignition wires 2032. In the elongated column at the center of the injection-molded part, two eyelets are fitted along the vertical centerline to allow the two multi-layer insulated withstand voltage wires of the two-pole ignition wires to pass through. This exposes the two-pole discharge end structure 2033 at the upper end of the multi-layer insulated withstand voltage wires outside the top of the elongated column in the injection-molded part. This structure serves to fix the ignition head and protect the ignition head and the two-pole discharge end structure. Preferably, as shown in the figure, the head of the two-pole discharge end structure is bent inwards in both directions using clamps to form a bent head. This innovative bent head structure eliminates the need for the installation and welding process of the heating bridge wire between the two poles of the ignition head 2034, and completely changes the electric ignition head structure of the heating bridge wire structure (i.e., the heating resistance wire structure in the prior art), improving the stability of the high-voltage pulse discharge and simplifying its overall structure. The integrated structure of the electric ignition component 203 with the wireless electromagnetic induction circuit magnetic block 201, which features the non-heating bridge wire structure, is one of the main technical innovations of this invention and also one of the core technologies of this invention.

[0056] Preferably, as shown in the figure, in the embodiment of this invention, to address the branching problem of the copper wires at the two poles, the copper wires at the two poles of this invention employ a multi-layer insulated, high-voltage-resistant wire + plastic sheath structure. This further solves the problem of fixing the copper wires at the two poles and facilitates their use and installation with dedicated bird-repelling launchers / guns. As described above, the injection-molded part and the copper wires near the propellant head are integrally injection molded in one piece, encasing the upper part of the copper wires at the two poles for protection. This fundamentally ensures the dual fixing structure and method for the copper wires at the two poles.

[0057] The product of this invention has demonstrated excellent performance in numerous trials and field tests. For example, when 100 randomly sampled unit components of the spark-type electric ignition assembly structure 203 of this invention were stored at (-30±1)℃ for 72 hours, a low-temperature ignition sensitivity test was conducted. Using ordinary piezoelectric ceramic ignition, all 100 unit components ignited. Another 100 unit components were stored at 65℃ and 95% humidity for 72 hours for a high-temperature and high-humidity test, and then all 100 ignited using ordinary piezoelectric ceramic ignition. This significantly outperforms the ignition rate of similar products.

[0058] In one exemplary embodiment of the present invention, further, as shown... Figure 1 , Figure 6 As shown, the inner bushing unit 3 of the electric ignition head is constructed using an injection molding structure and is cylindrical in shape. At the bottom center of the inner bushing unit, corresponding to the flame injection hole 4 at the center of its top surface, there is an electric ignition component inlet hole 301 for the electric ignition component structure 203 to pass through and connect. Multiple bushing chambers 302 are evenly arranged around the electric ignition component inlet hole. It should be noted that the injection molding structure of the inner bushing unit is made of anti-static plastic material to prevent the combustion and explosion of the propellant due to static electricity during the assembly of the bird-repelling ammunition unit 6, which could cause injury.

[0059] In one exemplary embodiment of the present invention, further, as shown... Figure 6 As shown, in one embodiment, the addition of an inner bushing unit for the electric ignition head and the assembly unit for the electromagnetic conductive electric ignition head not only ensures the electric ignition component structure in the electromagnetic conductive electric ignition head assembly unit is fixedly aligned and does not deviate from the flame jet hole above the bushing, thus protecting and fixing the entire assembly unit, but also serves as a carrier for the adhesion and bonding of the propellant layer. This solves the problem of the existing propellant carrier structure, more effectively ignites and burns the bird-repelling explosive projectile instantly, and effectively solves the problem of the paper tube of the projectile and the bird-repelling explosive projectile exploding together in the air, achieving the goal of leaving no paper scraps or other debris in the flight airspace.

[0060] In one exemplary embodiment of the present invention, further, as shown... Figure 3 As shown, the electric ignition assembly structure 203 described in this application is a spark-type electric ignition head structure or a non-propellant safety electric ignition head structure (not shown in this application).

[0061] In one exemplary embodiment of the present invention, further, as shown... Figure 4 , 5 As shown, the wireless electromagnetic induction circuit coil 202 described in this application is a PCB coil structure, which is an ultra-thin copper-clad laminate structure.

[0062] In one exemplary embodiment of the present invention, further, as shown... Figure 1 As shown, the launch cartridge body 1 described in this application is a cylindrical structure with one open end and one closed end, formed by injection molding of rigid plastic material. During assembly, the open end faces upward. The rigid plastic material is made of anti-static rigid plastic material.

[0063] The present invention also discloses another exemplary embodiment, which is characterized by the following structural features:

[0064] like Figure 8 As shown, the device includes a launch cartridge body 1, an electromagnetic conductive ignition head assembly unit 2 connected above the bottom surface of the inner cavity of the launch cartridge body, a propellant layer 5 bonded and fixedly connected to the lower panel of the electromagnetic conductive ignition head assembly unit, and a bird-repelling ammunition body unit 6 movably connected to the upper inner cavity of the launch cartridge body and connected to the top contact of the electromagnetic conductive ignition head assembly unit. The launch port end of the launch cartridge body is sealed by a sealing end cap 7. The above components are combined into an integrated bird-repelling ammunition device. The interval cavity formed between the bottom of the electromagnetic conductive ignition head assembly unit and the bird-repelling ammunition body unit enables the electromagnetic conductive ignition head assembly unit to ignite the propellant layer and the large amount of heat energy generated by the combustion at the bottom of the bird-repelling ammunition body unit simultaneously through electromagnetic induction heat / electricity conduction. This heat energy pressure is amplified in the sealed cavity, thereby directly pushing the bird-repelling ammunition body unit into the air, simplifying the processing technology and assembly process, and achieving a better bird-repelling effect.

[0065] Furthermore, in another embodiment of the technical solution, the electromagnetic conductive ignition head assembly unit 2 includes a radio electromagnetic induction circuit magnetic block 201, a radio electromagnetic induction circuit coil 202, two conductive terminals 205, an electric ignition assembly structure 203, and a propellant layer 5. The two conductive terminals are connected at the center of the radio electromagnetic induction circuit coil, and the electric ignition assembly structure is fixedly connected perpendicularly above the two conductive terminals. The propellant layer is bonded to the top of the radio electromagnetic induction circuit magnetic block. The radio electromagnetic induction circuit magnetic block has a copper-clad laminate structure, and the radio electromagnetic induction circuit coil has a PCB coil configuration.

[0066] Furthermore, in another embodiment of the technical solution, the copper-clad laminate structure on the magnetic block 201 of the radio electromagnetic induction circuit is an ultra-thin single-sided copper-clad laminate structure, on which the required PVB structure coil is printed.

In other words, the above-described embodiments are merely illustrative of the technical solutions of the present invention and should not be construed as limiting the invention in any way. Those skilled in the art should understand that the present invention has various well-known structural forms and / or material substitutions / alternatives, and all such substitutions / alternatives should be covered within the scope of protection of the present invention without departing from its essential meaning.
