Description
Technical Field
The application belongs to the technical field of bird repelling equipment, and particularly provides a pneumatic bird repelling bomb transmitting device.
Background
The problem of bird repelling in airports is a common problem which troubles the aviation industry of all countries around the world, because the motions are relative, the relative speed between an airplane and a bird is extremely high, if the airplane and the bird collide with each other, the airplane can be subjected to extremely high impact force, the bird strikes can damage the control surface of the airplane, puncture the skin or cockpit glass of the airplane and even damage the engine of the airplane, and the aviation safety is seriously influenced. Because of the influence of bird flight height, the aircraft take-off and landing process is the most vulnerable stage of bird strike, more than 90% of bird strike occurs in airport and airspace near the airport, and 50% of bird strike occurs in airspace below 30 meters, therefore, bird strike events always pose a serious threat to the flight safety of the aircraft.
Most of the existing mainstream bird repelling devices adopt an optical principle and an acoustic principle to repel birds.
Bird equipment that drives that utilizes optics to drive bird principle is mostly the laser and drives the bird ware, because the laser beam that the bird ware was driven to the laser is directional propagation and needs the laser beam to shine the eyes of bird just can exert and drive the bird effect, the event needs to carry out large-scale scanning with the laser beam just can exert better bird effect of driving, nevertheless because the laser beam also has the stimulation effect to people's eye, has the laser beam to shine pilot's eyes, and then influences the possibility of flight safety.
In the process of taking off and landing of the airplane, the sound of the airplane engine is high, flying birds near the airport can gradually adapt to the sound with high loudness along with the time, and the bird repelling effect is poor by singly using the sound with high loudness to repel the birds, so that the bird repelling bomb is emitted, and the bird repelling mode by using the light with sufficient intensity and the sound generated by the bird repelling bomb during the air explosion becomes the optimal choice of the airport.
Because the existing launching mode of the bird-repelling bomb is mostly to ignite the launching gunpowder of the bird-repelling bomb through the blasting fuse, the bird-repelling bomb is lifted by the airflow generated by the combustion of the launching gunpowder, the installation of the launching gunpowder needs special assembly requirements, and in order to ensure smooth ignition, a specific contact connection is required to be established between the blasting fuse and the ignition unit, if a plurality of bird repelling bombs are required to be launched, the blasting fuses of the bird repelling bombs are required to be connected to the ignition unit, the process needs professional personnel to operate in person, the connecting process is complicated, the automation degree is low, the number of shells ignited each time is limited, the timeliness is poor, a large amount of manpower and time are required to be invested only by connecting the fuse and the ignition unit, the user experience is poor, but also can influence the flexibility and the applicability of the bird-repelling bomb, and is difficult to adjust according to different occasions and different scenes.
The combustion process of the traditional bird-repelling bomb can be divided into two stages, wherein the first stage is a launching stage, and the second stage is an explosion stage. In the launching stage, launching the launching gunpowder through a pilot fire index, and the launching gunpowder burns to generate airflow to push the bird-repelling bomb so as to lift the bird-repelling bomb off; in the explosion stage, the launching gunpowder ignites a fuse between the launching gunpowder and the explosion gunpowder, and the fuse guides the explosion gunpowder to realize the explosion of the bird-repelling bomb. Due to the fact that the bird repelling bomb is inclined due to accidents in the launching process or is clamped too tightly in the launching process, or under other conditions, if the bird repelling bomb is clamped in the launching tube, the launching gunpowder cannot be combusted after being ignited, and the explosive gunpowder is ignited along with the lapse of time, the bird repelling bomb explodes in the launching position, the risk of explosion is caused, and great potential safety hazards exist in the launching mode. In the launching stage, obvious residues are left on the launching part of the bird-repelling bomb due to the combustion of the launching gunpowder, and the residue is easy to block the launching tube along with the time, so that the bird-repelling bomb is clamped in the launching tube; and the internal space of the bird-repelling bomb is limited, so that the gunpowder of the bird-repelling bomb needs to be divided into two parts, namely launching gunpowder and explosion gunpowder, so that the available space of the explosion gunpowder needs to give way to the available space of the launching gunpowder, and the maximization of the volume of the explosion gunpowder cannot be achieved.
The existing ignition mode of the bird repelling bomb needs to connect a fuse or other ignition units with an external ignition unit in a contact manner, the interior of the bird repelling bomb needs to be communicated with the outside during ignition, if precipitation occurs in rainy weather, the fuse is easy to be wetted by precipitation, so that ignition failure occurs, and if the method of igniting the propellant powder by heating through an electric heating wire is used for launching the launch mode of the bird repelling bomb, a circuit short circuit is easy to occur in rainy weather, so that the situation of ignition failure occurs.
