In related technologies, the working principle of bird repelling bombs is usually: ignite the fuse, and use the fuse to ignite the explosives in the sealed shell. Since the shell is in a sealed state, during the storage process, the bird repelling bombs are easily exposed to fire sources, impacts, etc., which can cause explosion accidents, affecting the safety of the storage of the bird repelling bombs. In addition, the fuse is always in contact with the explosives in the shell, and the fuse is more flammable, which further reduces the safety of the storage of the bird repelling bombs. Based on this, the present application proposes a special bomb for airport bird repelling. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model is a special bomb for driving away birds at airports, comprising a lower shell 1, a main shell 2 and an upper shell 3. An ignition plate 5 is fixedly connected to the bottom of the lower shell 1, a connecting lead 6 is fixedly connected to the middle of the inner cavity of the lower shell 1, the bottom of the connecting lead 6 is fixedly connected to the ignition plate 5, a fuse 4 is evenly fixed to the top of the connecting lead 6, and the top of the fuse 4 is flush with the top of the lower shell 1. By setting the ignition plate 5, the ignition area of the connecting lead 6 is increased, which is convenient for igniting the connecting lead 6. In some embodiments of the present application, the ignition plate 5, the connecting lead 6 and the fuse 4 are made of the same material. Preferably, the outer diameter of the ignition plate 5 is the same as the outer diameter of the lower shell 1.
[0023] The top of the lower shell 1 is threadedly connected to the main shell 2, and the bottom end of the inner cavity of the main shell 2 is fixedly connected to a support plate 7, on which a first explosive 11 is arranged. The first explosive 11 and the fuse 4 are both existing technologies and are not described in detail here. A connecting hole 9 is provided on the support plate 7, and the inner cavity of the connecting hole 9 is filled with the second explosive, and when the main shell 2 is fully threadedly connected to the lower shell 1, the bottom of the support plate 7 contacts the top of the lower shell 1, and the second explosive contacts the top of the fuse 4. With such a configuration, when the special bird-repelling bullet is in storage, the user screws the main shell 2 or the lower shell 1 so that there is a gap between the bottom of the main shell 2 and the lower shell 1. At this time, the main shell 2 and the lower shell 1 are in an incompletely threaded state, so that there is a gap between the second explosive and the fuse 4, which prevents the fuse 4 from igniting the second explosive and the first explosive 11, thereby improving the safety of the special bullet during storage; and when the special bullet is used, the user screws the main shell 2 or the lower shell 1 so that the bottom of the main shell 2 is tightly fitted with the lower shell 1. At this time, the main shell 2 and the lower shell 1 are in a fully threaded state, and the second explosive and the first explosive 11 can be ignited when the fuse 4 burns.
[0024] The surface of the lower shell 1 and the bottom of the support plate 7 are coated with a flame retardant coating. Through the setting of the flame retardant coating, the lower shell 1 has a flame retardant function, which prevents the fuse 4 from igniting the lower shell 1 and improves the protection effect.
[0025] The top of the main shell 2 is evenly provided with explosion-proof holes 1, which are located above the first explosive 11. An explosion-proof membrane 10 is fixed in the inner cavity of the explosion-proof hole 1. The explosion-proof membrane 10 can seal the explosion-proof hole 1 to prevent moisture and air from entering the shell and the first explosive 11 from getting damp. When the first explosive 11 burns, the explosion-proof membrane 10 ruptures before the shell under pressure, and the excess gas in the shell can be discharged through the explosion-proof hole 1, so as to prevent the special bird-repelling bullet from exploding during storage. The material of the explosion-proof membrane 10 can be selected according to demand and is not limited here.
[0026] The top of the main shell 2 is threadedly connected with the upper shell 3, and the side wall of the upper shell 3 is provided with a second explosion-proof hole 8, and when the upper shell 3 is completely threadedly connected with the main shell 2, the first explosion-proof hole and the second explosion-proof hole are in a staggered state, at this time, the inner cavity of the shell is in a sealed state, and the gas generated when the first explosive 11 burns is imprisoned by the shell, and the special bullet can explode, which is convenient for driving away birds. When the first explosion-proof hole and the second explosion-proof hole are in an overlapping state, it is convenient to release gas.
[0027] The outer diameters of the lower shell 1, the main shell 2 and the upper shell 3 are the same. The outer wall at the top of the main shell 2 and the outer wall at the top of the lower shell 1 are both provided with external threads, and the inner wall at the bottom of the main shell 2 and the inner wall at the bottom of the upper shell 3 are both provided with internal threads, and the external threads are adapted to the internal threads.
[0028] The side walls of the lower shell 1, the main shell 2 and the upper shell 3 are all hollow structures, and the inner cavities of the side walls of the lower shell 1, the main shell 2 and the upper shell 3 are all filled with bird repellent. When the special bullet explodes, the bird repellent splashes into the air to play the role of repelling birds. The shell of the special bird repellent bullet is set as a cylinder and adopts universal specifications, which is suitable for any common bird repellent launcher, thereby improving the practicality of the bird repellent bullet.
[0029] From the above description, it can be known that when the special bird-repellent bullet is stored, there is a gap between the fuse 4 and the second explosive to prevent the fuse 4 from igniting the first explosive 11, and an explosion-proof hole is provided on the cartridge case. When the first explosive 11 burns accidentally, the excess in the cartridge case can be discharged through the explosion-proof hole to prevent the special bullet from exploding, thereby improving the safety of the special bullet during storage, and the special bullet can spray bird repellent during the explosion process. The audio bird repellent and chemical bird repellent are combined to improve the bird repellent effect.
[0030] In summary: when the special bird-repelling bomb for airport is used, the user screws the upper shell 3 so that the upper shell 3 and the main shell 2 are in a state of complete threaded connection, and the lower shell 1 and the main shell 2 are in a state of complete threaded connection. At this time, the explosion-proof hole 1 and the explosion-proof hole 2 8 are in a staggered state, and the fuse 4 is in a contact state with the second explosive. The user loads the bird-repelling bomb into a launching device adapted thereto, and the launching device launches the bird-repelling bomb and ignites the ignition plate 5. The heat on the ignition plate 5 is transferred to the first explosive 11 through the connecting lead 6, the fuse 4 and the second explosive. The first explosive 11 is ignited, and the gas generated during the ignition of the first explosive 11 bursts the shell, and the special bird-repelling bomb explodes to achieve the bird-repelling function. At the same time as the shell explodes, the bird repellent in the shell is spilled to improve the bird-repelling effect.
