Pneumatic bird-repelling bullet firing device

Abstract

The invention discloses a pneumatic bird-repelling bullet firing device, and belongs to the technical field of bird-repelling equipment. Bird-repelling bullets used in cooperation with the pneumatic bird-repelling bullet firing device are provided with fuses, and the pneumatic bird-repelling bullet firing device comprises a firing tube, a gas supply unit and a non-contact ignition device, wherein the firing tube is internally provided with a bullet body movement channel, the bullet body movement channel communicates with the outside world through an outlet end of the firing tube, and the firing tube is further provided with a gas inlet which communicates with the bullet body movement channel; the gas supply unit can provide compressed gas for the bullet body movement channel through the gas inlet, so that the bird-repelling bullets in the bullet body movement channel are fired to the outside world through an outlet; and the non-contact ignition device is arranged outside the firing tube, and can ignite the fuses of the bird-repelling bullets which move in the bullet body movement channel in a non-contact mode. By means of the pneumatic bird-repelling bullet firing device of the structure, the efficiency of firing the bird-repelling bullets can be improved, the firing difficulty is reduced, and the firing safety is improved.

Description

technical field [0001] The application belongs to the technical field of bird repelling equipment, and specifically provides a pneumatic bird repelling projectile launcher. Background technique [0002] The problem of repelling birds at airports has always been a common problem that plagues the aviation industry of all countries in the world. Because the movement is relative, the relative speed between the aircraft and the bird is extremely high. If the two collide, the aircraft will suffer a great impact, and the bird strike may It will damage the control surface of the aircraft, penetrate the aircraft skin or cockpit glass, and even damage the aircraft engine, seriously affecting aviation safety. Due to the influence of the flight altitude of birds, the process of take-off and landing is the stage where bird strikes are most likely to occur. More than 90% of bird strikes occur in the airspace near the airport and 50% occur in the airspace below 30 meters. Therefore, it has...

[0002] The problem of repelling birds at airports has always been a common problem that plagues the aviation industry of all countries in the world. Because the movement is relative, the relative speed between the aircraft and the bird is extremely high. If the two collide, the aircraft will suffer a great impact, and the bird strike may It will damage the control surface of the aircraft, penetrate the aircraft skin or cockpit glass, and even damage the aircraft engine, seriously affecting aviation safety

Due to accidents during the launch process, the bird repellent projectile is skewed or the bird repellent projectile is too tightly clamped during the launch process, or other situations, such as the bird repellent projectile is jammed in the launch tube, and the gunpowder is fired. After being ignited, the combustion cannot be terminated. As time goes by, the explosive powder is ignited, causing the bird repellent bomb to explode at the launch point, which has the risk of exploding the chamber. This kind of launch method has a large safety hazard

During the launch phase, the bird repellent bomb will leave obvious residues at the launch site due to the burning of the propellant powder. Over time, the residue will easily block the launch tube, causing the bird repellent bomb to get stuck in the launch tube; and the internal space of the bird repellent bomb Limited, in order to realize the lift-off and explosion of the bird repellent bomb, the gunpowder of the bird repellent bomb needs to be divided into two parts: the launching powder and the explosive powder, so that the usable space of the explosive powder needs to make concessions to the usable space of the launching powder, which cannot be achieved Maximization of Explosive Powder Volume

[0008] The ignition method of the existing bird repellent bomb needs to connect the fuse or other ignition unit with the external ignition unit. When the bird repellent bomb is ignited, the interior of the bird repellent bomb needs to be connected with the outside world. If it encounters precipitation, the precipitation will easily wet the fuse and cause Ignition failure, if the bird repellent bomb is launched by using the heating wire to heat and ignite the gunpowder, the circuit short circuit is very likely to occur in rainy weather, resulting in ignition failure.
