Description

Bird-scaring gun and bird-scaring gun system

Technical Field

The application relates to the technical field of bird repelling devices, in particular to a bird repelling cannon. The application also provides a bird-scaring gun system.

Background

The aircraft take-off and landing process is the most vulnerable stage to bird strikes, more than 90% of which occur at and near airports and 50% of which occur in less than 30 meters of airspace, and therefore bird strike events have always posed a serious threat to the flight safety of aircraft. The existing mainstream bird repelling equipment basically adopts an acoustic (such as a sound wave bird repelling device) or optical (such as a laser bird repelling device and a horror eye) principle to repel birds, the equipment is easy to adapt to birds after being used for many times, the aim of repelling the birds is difficult to achieve by only using sound and optical effects, and the equipment can bring unnecessary sound and light pollution to airports and surrounding environments and even cause certain influence on operators and surrounding residents.

Through continuous attempts, some airports begin to adopt the emission of solid shells to repel birds, two kickers and titanium bombs are two most common and typical bird repelling bombs, and generally adopt a two-section type gunpowder ignition process to directly ignite to realize the detonation propulsion effect of a first stage, so that the solid shells fly to the flying birds, and the second stage of explosion is finished in the air in an area close to the flying birds to generate multiple sensory effects such as sound, flash, shock waves and the like. Years of application practice shows that the bird repelling bomb is the bird repelling mode which has the best bird repelling effect and the highest efficiency and is most suitable for birds at present.

However, the existing bird-repelling bomb also has a plurality of practical problems,

the method is characterized in that firstly, the existing entity shell needs naked fire or electric ignition to ignite a fire guide cable, so that special assembly requirements are required for ignition, if smooth ignition is ensured, a specific connecting structure between a fire guide cable ignition device and a bird repelling bomb needs to be established, the process needs professional personnel to operate in person, the operation is complex, the automation degree is low, the number of shells ignited each time is very limited, the timeliness is poor, a large amount of manpower and time need to be invested only in operation, the operation is inconvenient and limited, the use flexibility and the use adaptability can be further influenced, and the adjustment can be difficult to carry out according to different occasions and different scenes. Even if open fire or electric ignition is adopted to ignite the fuse, the fuse can be ignited only after a period of time is maintained when the fuse is ignited, so that the timeliness is poor, and the emission efficiency is low.

Secondly, when the weather is rainy, the mode of igniting the fuse by naked flame and electric ignition is not suitable, and especially the electric ignition mode obviously has great potential safety hazard and may cause fire, explosion and other safety accidents due to short circuit.

Finally, most of the existing solid projectiles are of a two-stage design, the ignition of the first stage of the existing solid projectiles requires explosion to generate propulsive force, which can challenge the safety of the launching process, for example, the solid projectiles are stuck in the launching device during the movement of the solid projectiles after the explosion of the first stage, which causes the explosion of the second stage in the launching device, and unpredictable explosion can be caused by ignition errors or other accidents, which is a test for operators and launching devices.

In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.

It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and thus the scope of the present application is not limited by the specific embodiments disclosed below.

Fig. 1 is a schematic structural diagram of an exemplary embodiment of a bird scaring gun. As shown in fig. 1, the bird scaring gun includes a launching tube 10, a launching device 20, a magnetic field generating unit 40 and an electric energy storage unit 30. Wherein the content of the first and second substances,

the projectile motion channel 13 is arranged inside the launching tube 10, one end of the launching tube 10 with an outlet is an outlet end 11, and the projectile motion channel 13 is communicated with the outside through the outlet end 11 of the launching tube 10, which can be seen in fig. 2. The launching device 20 is disposed at the other end of the launching tube 10, and is capable of driving the bird-repelling bomb 60 located in the bomb body moving channel 13 at the other end of the launching tube 10, so that the bird-repelling bomb moves along the axial direction of the launching tube, moves from the other end of the launching tube to the exit end and reaches the highest speed at the exit end, and is launched to the outside through the exit end. The electric energy storage unit 30 can be externally connected with a power supply to store electric energy. The magnetic field generating unit 40 is disposed outside the launching tube 10, and may be referred to as fig. 2, and is connected to the electric energy storage unit 30, and may be referred to as fig. 1 or fig. 2, the electric energy storage unit provides stored electric energy to the magnetic field generating unit, so that the magnetic field generating unit generates an ignition magnetic field in the projectile body movement passage, and may be referred to as fig. 3, fig. 3 is a schematic diagram of the bird repelling bomb 60 passing through the ignition magnetic field, and an electromagnetic induction fuse of the bird repelling bomb passing through the ignition magnetic field can be ignited instantly.

In the operation process of the bird scaring gun, under the power supply of the electric energy storage unit 30, the magnetic field generating unit 40 forms an ignition magnetic field in the projectile body movement channel 13 of the launching tube 10, as can be seen from fig. 3, fig. 3 is a schematic diagram of the bird scaring projectile passing through the ignition magnetic field. The bird-repelling bomb 60 is initially placed at the other end of the bomb-moving channel 13 opposite to the exit end 11, the launching device 20 gives a driving force to the bird-repelling bomb 60 along the bomb-moving channel 13 at the other end, so that the bird-repelling bomb 60 is accelerated to move along the axial direction of the bomb-moving channel 13 (see arrow direction in fig. 2), the bird-repelling bomb 60 passes through the ignition magnetic field when moving in the bomb-moving channel 13, the electromagnetic induction fuse of the bird-repelling bomb 60 is ignited instantaneously when passing through the ignition magnetic field, at this time, the bird-repelling bomb 60 has the highest speed, after being ignited by the electromagnetic induction fuse, the bird-repelling bomb 60 continues to move along the axial direction of the bomb-moving channel 13 until being ejected from the exit end 11 of the launching tube 10, the electromagnetic induction fuse of the bird-repelling bomb 60 ignites the internal fuse, the fuse of the bird-repelling bomb 60 burns for a period of time after being ignited, and then ignites the explosive in the bird-repelling bomb 60, the bird flying device can explode after flying for a period of time in the air, so that the birds can be expelled.

The design of the bird-scaring cannon magnetic field generating unit 40 ensures that the bird-scaring bomb 60 can be ignited internally when passing through a magnetic field at high speed, the non-contact ignition mode does not need to consider the establishment of a static matching relationship between the bird-scaring bomb 60 and an ignition device, particularly does not need to establish a direct connection structure, for example, a wire connection is established between the launching equipment and the bird-scaring bomb, structural limitation can not be caused on the launching, the loading and the loading of the bird-scaring bomb 60, and particularly remarkable convenience is provided from the aspect of use and operation, for example, the possibility of realizing automatic loading and the possibility of automatic launching and ignition are provided, and the labor cost and the time cost which are input in use and operation can be greatly saved.

More importantly, the magnetic field generating unit 40 generates the ignition magnetic field (see fig. 1) by the control of the electric energy storage unit 30, which is connected to an external power source and stores electric energy and then supplies the stored electric energy to the magnetic field generating unit, which starts to operate and generates the ignition magnetic field upon receiving the power supply from the electric energy storage unit. The advantage of this design is that the time during which the magnetic field generating unit generates the ignition magnetic field can be controlled by controlling the power supply of the electrical energy storage unit to the magnetic field generating unit. For example, when the ignition magnetic field is not needed, the electric circuit between the electric energy storage unit and the magnetic field generating unit is opened, and the magnetic field generating unit cannot generate the ignition magnetic field. And after the electric energy storage unit stores the electric energy, when the magnetic field generation unit is communicated, the electric energy storage unit instantly generates impact current to the magnetic field generation unit, so that the magnetic field generation unit instantly generates a magnetic field with enough strength to ignite the electromagnetic induction fuse. In a preferred embodiment, the electric energy storage unit has an energy storage capacitor, when the external power supply charges the electric energy storage unit, a certain voltage can be stored across the energy storage capacitor, and then the external power supply stops supplying power, and the energy storage capacitor starts to supply power to the magnetic field generating unit 40 connected to the electric energy storage unit 30, and the power is supplied by the energy storage capacitor. The energy storage capacitor has the advantage of a fast discharge, which can supply its stored electrical energy to the magnetic field generating unit 40 instantaneously or within a few milliseconds, so that the magnetic field generating unit 40 can rapidly generate an ignition magnetic field.

In order to improve the automation degree of the bird scaring gun and further save energy, the electric energy storage unit 30 can intermittently supply power to the magnetic field generation unit, namely, the electric energy storage unit 30 supplies power to the magnetic field generation unit 40 only when the bird scaring bomb 60 moves in the bomb body movement channel 13, so that the pressure of continuous operation of a circuit is reduced, a certain protection effect is realized on the circuit, and the electric energy is saved. In a preferred embodiment, the bird scaring gun further comprises a control unit 50, as shown in fig. 2, the control unit 50 sends a release signal when the launching device 20 starts to drive the bird scaring bomb 60, and the electric energy storage unit 30 releases the stored electric energy to the magnetic field generating unit 40 after receiving the release signal. Specifically, when the bird-scaring gun receives a gun-opening instruction, the launching device 20 starts to operate and provides a driving force for the bird-scaring bomb 60 placed in the bomb body moving channel 13, in order to realize reliable ignition, at the moment, the control unit 50 sends a release signal to the electric energy storage unit 30, the electric energy storage unit 30 starts to supply power to the magnetic field generating unit 40, the magnetic field generating unit 40 generates an ignition magnetic field, then the bird-scaring bomb 60 moves along the axial direction of the launching tube 10 under the action of the driving force, and an internal electromagnetic induction fuse is ignited until the bird-scaring bomb passes through the ignition magnetic field. The time of movement of the bird projectiles 60 within the projectile movement passage 13 is typically tens of milliseconds, so the electrical energy storage unit 30 is operated simultaneously when the bird projectiles 60 are to be fired, so that the ignition field has time to be able to generate sufficient electromagnetic energy to ignite the bird projectiles 60. The control unit 50 is arranged to prevent the electric energy storage unit 30 from continuously supplying power to the magnetic field generating unit 40, so that the magnetic field generating unit 40 can be prevented from being damaged due to continuous operation, and the magnetic field generating unit 40 has a longer service life; in addition, the control unit 50 controls the electric energy storage unit 30 to supply pulse power to the magnetic field generating unit 40, so that the generation time of the ignition magnetic field is matched with the bird-repelling bomb 60 emitted by the emitting device 20, the effect that the bird-repelling bomb 60 is instantly ignited in the emitting process is realized, the emitting process of each bird-repelling bomb 60 is repeated, and the automation degree of the bird-repelling bomb automatic emitting and the non-contact ignition is improved.

In a preferred embodiment, the magnetic field generating unit 40 has a series resonant high-frequency inverter circuit capable of generating a high-frequency alternating electromagnetic field, which forms the ignition magnetic field. The series resonant high frequency inverter circuit, when energized, releases a substantial amount of electromagnetic energy sufficient to ignite its electromagnetic induction fuse as the bird repellent bomb 60 passes by. After the control unit 50 sends a release signal to the electric energy storage unit 30, the magnetic field generation unit 40 is powered on, the series resonance high-frequency inverter circuit starts to work to generate an ignition magnetic field formed by a high-frequency alternating electromagnetic field, and at the moment, the bird repelling bomb 60 does not move to an ignition magnetic field area, so that the ignition magnetic field is in an idle state, and in order to realize reliable ignition, the idle state is unavoidable, the inverter circuit can form a stable and high-strength ignition magnetic field in the idle state, the inverter circuit is favorable for rapidly converting from an energy storage standby state to a full power output state, so that the bird repelling bomb 60 can be instantly ignited when passing through the ignition magnetic field, after the bird repelling bomb 60 is ignited and is emitted out of the emission tube 10, the electric energy storage unit 30 stops supplying power to the magnetic field generation unit 40, the inverter circuit stops working, and because the bird repelling bomb 60 moves in the bomb moving channel 13 for a short time, usually only a few milliseconds, so that short-time idling of the inverter circuit is allowed without thereby damaging or reducing the service life of the inverter circuit.

In an embodiment of the present application, the bird-scaring gun may further include a photoelectric sensor disposed in the projectile motion channel 13, wherein the photoelectric sensor is disposed in front of the magnetic field generating unit 40 on the launching stroke of the bird-scaring projectile 60, and the photoelectric sensor outputs a control signal after sensing the bird-scaring projectile 60; the electric energy storage unit 30 instantaneously releases the electric energy to the magnetic field generating unit 40 upon receiving the control signal. Through the photoelectric sensor who sets up can sense bird bullet 60 and pass through and can output control signal, magnetic field generating unit 40 can produce the magnetic field that ignites according to control signal for drive bird bullet 60 and pass through when igniting the region magnetic field and produce, thereby make the electromagnetic induction fuse in the bird bullet 60 of driving ignited smoothly, then can realize accurate ignition. On the one hand, the ignition magnetic field can accurately ignite each launched bird-repelling bomb, and on the other hand, compared with the situation that the ignition magnetic field is started when the bird-repelling bombs are just launched, the photoelectric sensor is arranged, so that the working time of the magnetic field generating unit is shorter, and the service life of a circuit in the magnetic field generating unit is longer. In another embodiment, timing can be started when the bird-scaring cannon is just driven by the launching device in a timing mode, the magnetic field generating unit is started to generate an ignition magnetic field when twenty milliseconds occur, and the ignition magnetic field is generated before the bird-scaring cannon passes through the ignition area through the movement of the bird-scaring cannon in the launching pipe.

To prevent a failed launch of the bird-repelling bombs 60 by jamming or the like in the bomb-moving passage 13, a magnetic field generating unit 40 is provided outside the outlet end 11, see fig. 2, which is capable of forming an ignition magnetic field in the bomb-moving passage 13 at the outlet end 11, see fig. 3. Because the bird repelling bomb 60 always keeps high-speed movement in the bomb body movement channel 13, the bird repelling bomb 60 also has a quite high speed when passing through the ignition magnetic field, the magnetic field generating unit 40 is arranged at the outer side of the outlet end 11 and can be ignited when the bird repelling bomb 60 passes through the outlet end 11, at the moment, the bird repelling bomb 60 with the speed can naturally break away from the launching tube 10 from the outlet end 11 and can be successfully launched out of the bird repelling cannon without being hindered by the bomb body movement channel 13 after being ignited, and the danger of explosion of the chamber can be effectively avoided. When the bird repelling bomb 60 does not move to the ignition magnetic field position in the bomb body moving channel 13 and is blocked and cannot be ejected, the bird repelling bomb 60 is not ignited at the moment, even if the bird repelling bomb is reserved in the ejecting pipe, no risk exists, and the bird repelling bomb can be continuously ejected again even after the reason that the bird repelling bomb cannot be ejected is checked. Of course, the magnetic field generating unit may also be disposed inside the launching tube at the outlet end as long as the electromagnetic induction fuze of the bird-repelling bomb can be ignited at the outlet end.

The further optimization of the ignition of the bird-repelling bomb at the outlet end is that the caliber of the bomb moving channel 13 close to the outlet end 11 is larger than the calibers of the bomb moving channels 13 at other positions, as shown in fig. 2, the design can prevent the bird-repelling bomb 60 from being incapable of being normally ejected due to blockage when passing near the outlet end 11, and as long as the bird-repelling bomb 60 has a certain speed when passing near the outlet end 11, the bird-repelling bomb 60 can be ejected from the outlet end 11 with a larger caliber, so that the danger of explosion of the bird-repelling bomb 60 is fundamentally avoided.

In one embodiment, the ignition magnetic field is an alternating magnetic field, and to achieve instantaneous ignition of the electromagnetic induction fuse in the bird repellent bomb 60, the magnetic field direction is generally set to the direction shown in fig. 3, but is not limited to the direction design. Therefore, the bird-repelling bomb 60 can be instantly ignited by the ignition magnetic field when passing through the ignition magnetic field, and non-contact instant ignition can be realized even in the high-speed launching process of the bird-repelling bomb 60. Therefore, the driving mode of the bird-repelling bomb 60 does not need to depend on the first-stage explosion propelling section in the existing double-stage solid shell, and the explosion section of the bird-repelling bomb 60 without the first-stage explosion propelling section can still be successfully ignited in motion, so that the driving mode of the bird-repelling bomb 60 has more possibility.

For example, in a preferred embodiment, the bird-repelling bomb 60 provided by the present application can be driven to the high altitude in a pneumatic manner, before the bird-repelling bomb 60 is driven to leave the launching tube 10, the electromagnetic induction fuse can be ignited by the magnetic field generating unit 40, and when the bird-repelling bomb 60 is driven to a certain high altitude position, the bird-repelling bomb 60 can explode. In a particular embodiment, the launch tube 10 is further provided with an air inlet 12 communicating with a projectile motion channel 13, see fig. 1; the launching device 20 is a gas supply assembly, as shown in fig. 4, the gas supply assembly includes an air compressor, an air storage tank for storing compressed air prepared by the air compressor, and a launching tank connected to the air storage tank, the air storage tank delivering the compressed air to the launching tank, and the launching tank being connected to the air inlet 12 of the launching tube 10 through a valve. Which can supply compressed gas to the projectile motion passage 13 through the gas inlet 12 to drive the bird repelling bombs 60 to move in the axial direction of the launching tube 10. The cold ejection launching mode does not need consumable materials such as heating wires and gunpowder required by the traditional launching mode, only needs compressed air, and therefore pneumatic launching is more economical. After the transmission is finished, gas can be returned to the atmosphere, black smoke generated by burning of transmission powder in the traditional transmission process can not be generated during transmission, other substances are not generated in the transmission process, the transmission mode of pneumatic transmission is more environment-friendly, and the transmission material required by pneumatic transmission is easy to obtain. Of course, in addition to being pneumatically powered, it will be understood by those skilled in the art that the bird projectiles 60 may also provide the driving force for launch by any means available in the art.

Due to unpredictability of explosion propulsion, the conventional solid cannonball cannot effectively and accurately control the self propulsion height and cannot adapt to different use scenes and requirements. The bird-scaring cannon abandons the mode of propelling the bird-scaring bomb 60 to lift off through explosion, and other driving modes are utilized to avoid influencing internal ignition, for example, the lifting height of the bird-scaring bomb 60 can be controlled more accurately through a pneumatic driving mode, and the bird-scaring cannon is easy and flexible to change according to different use scenes and requirements, for example, the lifting height of the bird-scaring bomb 60 can be controlled through accurately controlling the pressure of driving gas.

No matter the launching device 20 is in a pneumatic or other driving mode, the bird-scaring gun can adopt a cold ejection launching device 20, when the bird-scaring bullet 60 is in the bullet moving channel 13 and does not pass through the time period of an ignition magnetic field, the electromagnetic induction fuse of the bird-scaring bullet cannot be ignited, the electromagnetic induction fuse is ignited until the bird-scaring bullet 60 moves to the position of the outlet end 11, and the bird-scaring bullet 60 reaches the maximum moving speed at the position of the outlet end 11 after passing through the acceleration in the bullet moving channel 13, so the bird-scaring bullet can be smoothly ejected from the launching tube 10 after being ignited, the safety of the bird-scaring gun during use is obviously improved, and potential safety hazards such as bore explosion caused by unsuccessful launching after ignition (jamming or insufficient driving force is encountered in the launching tube 10) can be effectively prevented.

The application also provides a bird-scaring cannon system, including driving the bird cannon, still including installing bird-scaring bullet 60 of closed-loop heating element 61, can refer to fig. 5, closed-loop heating element 61 through the ignition magnetic field can form closed-loop short-circuit current to turn into the heat energy with electromagnetic energy and ignite and drive bird bullet 60. When the bird repelling bomb 60 passes through the ignition magnetic field, the alternating electromagnetic field passes through the closed loop heating element 61, as shown in fig. 7, the induction lines of fig. 7 pass through the closed loop heating element from the paper surface inwards, and conceivably, the induction lines of the alternating electromagnetic field are rapidly switched between the two directions of passing through the paper surface inwards and passing through the paper surface outwards, so that the magnetic flux passing through the closed loop heating element is changed. According to the electromagnetic induction principle, short-circuit closed-loop current is generated on the closed-loop heating piece 61, and then according to the Joule law, the current flows on the closed-loop heating piece 61 to generate heat energy to raise the temperature of the closed-loop heating piece 61, so that electromagnetic energy is converted into the heat energy on the closed-loop heating piece 61 to ignite a fuse in the bird repelling bomb 60, and the fuse continuously burns for a period of time to detonate explosives in the bird repelling bomb 60. The magnetic field generating unit 40 is matched with the bird repelling bomb 60 with the closed-loop heating piece 61, non-contact electromagnetic ignition can be realized within a very short time, and the operation efficiency of the bird repelling bomb system is improved. In a preferred embodiment, the magnetic field generating unit 40 includes a series resonance high frequency inverter circuit, the closed loop heating element 61 of the bird repelling bomb 60 is located at the load end of the inverter circuit when the bird repelling bomb is located in the ignition magnetic field, the inverter circuit can be equivalent to a voltage source, and when the load end of the bird repelling bomb is the short-circuited closed loop heating element 61, the inverter circuit can output extremely large instantaneous power, so that the temperature of the closed loop heating element 61 is instantly increased, and the instantaneous ignition of the bird repelling bomb 60 is realized. This is completely different from the conventional high frequency induction heating in that the eddy current is generated inside the magnetic conductor, and the closed loop heating element 61 is matched with the magnetic field generating unit 40 to achieve the purpose of instant ignition better. Because the speed of the bird repelling bomb 60 is extremely high, and the temperature of the closed-loop heating piece 61 is sharply increased under the action of huge short-circuit current circulation, the closed-loop heating piece 61 is blown after the temperature reaches the ignition point of the fire wire rapidly, so that the inverter circuit can be out of the state of short circuit at the load end, and the process lasts for only a few milliseconds, therefore, the bird repelling bomb can completely bear the inverter circuit, and the normal work and the service life of the inverter circuit cannot be influenced.

The closed-loop heating element 61 is further optimized in that the closed-loop heating element 61 is a circular ring-shaped heating sheet, as shown in fig. 6, when the bird repelling bomb 60 is located in the bomb body movement channel 13, the axial direction of the bird repelling bomb is collinear with the axial direction of the launching tube 10. The circular ring sheet structure is the shape most sensitive to the electromagnetic induction phenomenon, and on the basis of ensuring the closed ring structure, the circular ring sheet structure can ensure the electromagnetic induction end face with the largest area and the minimum ignitable volume, and the smaller the ignitable volume is, the faster the temperature rise is, and the higher the highest temperature is. And the annular heating sheet has small volume, is basically completely smashed after the bird-repelling bomb 60 explodes, and can not leave obvious solid residues. Because the axial direction of the annular heating sheet and the magnetic induction line direction of the ignition magnetic field have the optimal angle, referring to fig. 5, the bird repelling bomb 60 can adopt a cylindrical bird repelling bomb 60, the annular heating sheet is arranged in the bird repelling bomb 60, the axial direction of the annular heating sheet is collinear with the axial direction of the bird repelling bomb 60, and the axial direction of the bird repelling bomb 60 is collinear with the axial direction of the bomb moving channel 13 when moving in the bomb moving channel 13, so that the axial direction of the annular heating sheet is collinear (the optimal angle) with the axial direction of the launching tube 10 when passing through the ignition magnetic field, and the advantage of the circular ring in geometry relative to other shapes (the circle with the same circumference has the largest area) is considered, so that the alternating magnetic induction line passing through the annular heating sheet is the largest, the induction temperature rise of the annular heating sheet is the fastest, and the best instant ignition efficiency is realized.
