Description

Technical Field

[0001] This utility model relates to the field of bird deterrence equipment technology, and in particular to a bird deterrence projectile launcher. Background Technology

[0002] Bird deterrent launchers are widely used in bird control operations at major airports both domestically and internationally. By using bird deterrent launchers, airports can effectively reduce bird strikes and ensure aviation safety and smooth operations. In addition, bird deterrent launchers are also suitable for other locations requiring bird control, such as farmland and orchards.

[0003] The existing mainstream bird deterrence equipment mainly uses acoustic (such as sonic bird deterrents) or optical (such as laser bird deterrents and terror eyes) principles to deter birds. These devices are easily adapted to by birds after repeated use, so it is difficult to achieve the goal of bird deterrence by sound and optical effects alone. Moreover, these devices will bring unnecessary sound and light pollution to the airport and the surrounding environment, and may even have a certain impact on operators and nearby residents.

[0004] Some airports have begun using solid projectiles to scare away birds. Two-stage firecrackers and titanium-plated firecrackers are two of the most commonly used bird-scare projectiles. They generally employ a two-stage gunpowder ignition process. Direct ignition achieves the first stage of explosive propulsion, propelling the projectile towards the bird. The second stage of explosion occurs in mid-air near the bird, producing a multi-sensory effect including sound, flash, and shockwave. Years of practical application have shown that this type of bird-scare projectile is currently the most effective, efficient, and least adaptable method for bird control.

[0005] Bird deterrent projectile combustion can be divided into two stages: the first stage is the launch stage, and the second stage is the explosion stage. In the launch stage, a fuse ignites the propellant, and the combustion of the propellant generates an airflow that propels the bird deterrent projectile into the air. In the explosion stage, the propellant ignites the fuse between itself and the explosive propellant, which in turn ignites the explosive propellant, causing the bird deterrent projectile to explode. The structure of a bird deterrent projectile typically includes the following main parts: the cartridge case, the propellant, the payload (such as an acoustic device, a flash device, or an object), and the fuse. However, existing bird deterrent projectiles have some problems, such as low ignition rate and susceptibility to malfunction; complex installation, inconvenient angle adjustment, and poor stability.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The bird deterrent projectile launcher of this utility model has a rotatable gun mount mounted on a support frame. The angle of the gun mount can be adjusted by the handle assembly to adapt to different operational needs. The ignition mechanism is mounted on the protective mechanism. The ignition rod needle and the fuse are fitted together. The ignition rod is heated by electricity. After the ignition rod needle is heated, it ignites the fuse of the projectile, improving the accuracy of ignition and achieving a 100% ignition rate.

[0021] (2) The installation and protection mechanism of the bird deterrent projectile launcher of this utility model has a hollow cylinder on the lower surface of the upper mounting plate. When igniting, the projectile fuse is heated and ignited by the ignition rod needle. Since there is a cylinder below the upper through hole, most of the ignition rod needle is placed inside the cylinder or below the cylinder, with the upper end extending into the upper through hole. Therefore, the impact of the explosion of the ignited projectile on the ignition rod needle is reduced, thus avoiding the breakage of the ignition rod needle.

[0022] (3) The cannon body of this utility model is mounted on a support base. The handle assembly is used to rotate the cannon body and fix its angle, and also has an anti-fall function. The device consists of a pin, an angle limiting plate, a handle rotation shaft, a handle, and a limiting pin. By rotating the handle, the position of the pin inserted into the pin limiting hole on the angle limiting plate is adjusted to adjust the angle of the bird deterrent cannon. The limiting pin always slides within the limiting groove, which can prevent the bird deterrent cannon from falling. That is, the rotating and fixing device of this utility model can adjust the rotation angle of the bird deterrent cannon at multiple angles according to the actual working needs, while also preventing the bird deterrent cannon from falling. The equipment operates stably and is easy to operate.

[0023] (4) The bird deterrent launcher of this utility model is equipped with a fire-resistant mechanism. The device is in the shape of a launcher and is composed of multiple long partitions connected to a mounting base. It is mainly used to isolate each cannon barrel into an independent space. Each isolated space has a separate ignition device and a cannon barrel. The cannon barrel has a projectile fuse placed on the ignition device. This prevents the flames from the projectile after it explodes in the cannon barrel from flying into other cannon barrels, causing the fuses of other projectiles to ignite and explode, thus achieving the effect of precise control of the launch.

[0041] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0042] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0043] like Figures 1 to 8As shown, a bird-repelling projectile launcher according to a specific embodiment of this utility model includes: a support base 1, a gun carriage 2, multiple gun barrels 3, a handle assembly 4, an ignition mechanism 5, and a mounting and protective mechanism 6. The gun carriage 2 is rotatably mounted on the support base 1, and the rear side of the gun carriage 2 is provided with an openable and closable rear cover 7. The rear sections of the multiple gun barrels 3 are spaced apart from each other and parallel to each other on the gun carriage 2, with their front ends extending outwards from the gun carriage 2. The rear side of the gun carriage 2 is provided with an openable and closable rear cover 7, and the inner side of the rear cover 7 is provided with a sealing ring 71, which covers and seals the rear ends of the gun barrels. The handle assembly 4 is mounted on the support base 1 and connected to the gun carriage 2, and is used to adjust the rotation angle of the gun carriage 2. Ignition mechanisms 5 are configured one-to-one with the multiple cannon barrels 3. Each ignition mechanism 5 includes an ignition rod 51 and an ignition rod needle 52. The lower end of the ignition rod 51 is equipped with an electric wire 53, and the upper end is equipped with the ignition rod needle 52. The electric wire 53 is connected to a 12V power supply, which heats the ignition rod. A protective mounting mechanism 6 is configured one-to-one with the ignition mechanism 5. The ignition mechanism 5 is mounted on the rear side of the gun carriage 2, located at the rear end of the cannon barrel 2. The ignition rod needle 52 is in contact with the fuse of the projectile inside the cannon barrel. The ignition rod needle of the ignition mechanism 5 ignites the fuse of the projectile, launching the projectile through the front end of the cannon barrel 3.

[0044] The ignition mechanism 5 includes an ignition rod 51 and an ignition rod needle 52. The lower end of the ignition rod 51 is provided with an electric wire 53, and the upper end is provided with the ignition rod needle 52. The electric wire 53 is connected to a 12V power supply, which heats the ignition rod. The ignition rod 51 is mounted on a protective mounting device 6. The protective mounting device 6 includes a U-shaped mounting plate, comprising an upper mounting plate 61 and a lower mounting plate 62, which are integrally formed. The upper mounting plate 61 has a through hole 63 on its surface. A hollow cylinder 64 is located on the lower surface of the upper mounting plate 61 directly below the through hole 63, with the cavity of the cylinder 64 penetrating both the upper and lower surfaces. The lower mounting plate 61 is provided in the through lower hole 65, which is on the same vertical line as the upper through hole 63 and the cylinder 64. The lower mounting plate 62 is provided on the gun carriage 1 and is located close to the gun barrel 3.

[0045] With the ignition rod in the installed state, the lower end of the ignition rod 51 passes through the lower through hole 65 of the lower mounting plate 62, and the upper ignition rod needle 52 extends into the cavity of the cylinder 64, extending beyond the upper end of the cylinder 64, and into the upper through hole 63 of the upper mounting plate 62. The shell fuse 31 loaded in the barrel 3 should be placed in the upper through hole 63 of the upper mounting plate, fitting snugly against the ignition rod needle 52. During ignition, the ignition rod 51 is energized and heated, and the heat is conducted to the ignition rod needle 52. The shell fuse contacts the ignition rod needle 52, and when the ignition rod is heated, the fuse ignites, igniting and firing the shell. At the same time, because there is a cylinder 64 below the upper through hole, most of the ignition rod needle is placed inside or below the cylinder, with only a small part of the upper end extending into the upper through hole. Therefore, the impact force of the shell explosion on the ignition rod needle is reduced, preventing the ignition rod needle from breaking.

[0046] Preferably, the mounting plate has an asymmetrical U-shaped structure, with the lower mounting plate 62 being longer than the upper mounting plate 61. The longer lower mounting plate 62 facilitates installation on the gun mount 1.

[0047] Preferably, the upper through hole 63 of the upper mounting plate 62 is a through hole formed by two partially overlapping circles. That is, the upper through hole is an elongated hole formed by two semicircles, one semicircle is used to place the ignition rod needle 52, and the other semicircle is used to place the shell fuse.

[0048] Preferably, the upper through hole 63 of the upper mounting plate is an elongated hole. The lower through hole 65 of the lower mounting plate is an elongated hole. The lower mounting plate is provided with a mounting hole 66, which is an elongated hole, and the mounting hole 66 and the lower through hole 65 are on the same center line. The fact that both the lower through hole 65 and the mounting hole 66 of the lower mounting plate are elongated holes facilitates the adjustment of the position of the ignition rod needle in the upper through hole of the upper mounting plate, thereby improving the accuracy of ignition.

[0049] Preferably, the support base 1 includes a first base 11 and a second base 12. The gun carriage 2 is rotatably connected to the first base 11 and the second base 12 and is located between the first base 11 and the second base 12. The handle assembly 4 is disposed on the first base 11. The angle of the bird deterrent projectile launcher can be adjusted by rotating the gun carriage 2 through the handle assembly 4 to adapt to different operational needs.

[0050] The specific structure is as follows: A sleeve 121 is provided on the second base 12, and a rotating shaft (not shown in the figure) is provided inside the sleeve 121. The right end of the rotating shaft is connected to the gun mount 2. The handle assembly 4 is provided on the first base 1. The handle assembly 4 includes an angle limiting plate 41, a rotating sleeve 42, a limiting pin 43, a handle 44, and a pin 45. The angle limiting plate 41 is provided on the first base 11 and is fitted to the first base 11. The angle limiting plate 41 has a through arc-shaped limiting groove 411 and multiple pin limiting holes. The arc of the limiting groove 411 is a quarter circle arc and is located in the third quadrant of the coordinate system. This embodiment has three pin limiting holes, namely the first pin limiting hole 412, the second pin limiting hole 413, and the third pin limiting hole 414. Three pin limiting holes are distributed along the outer edge of the limiting groove 411. The first pin limiting hole 412 is located near the upper end of the limiting groove 411, and the second pin limiting hole 413 and the third pin limiting hole 414 are located near the middle and lower sections of the limiting groove 411.

[0051] A rotating sleeve 42 is mounted on the first base 11. A horizontally positioned rotating shaft 421 is located inside the rotating sleeve 42, with its front end extending beyond the front end of the rotating sleeve 42 and connecting to the gun mount 2. A limiting pin 43 is connected to the rotating sleeve 42 at its rear end, and its front end is slidably positioned within a limiting groove 411. The front end of the limiting pin 43 is always positioned within the limiting groove 411. When the gun mount 2 rotates, the limiting pin 43 slides within the limiting groove 411, providing continuous support to the angle limiting plate 41 and preventing it from falling off. A handle 44 is rotatably connected to a handle rotating shaft 46 via a connector 441. The handle rotating shaft 46 is vertically positioned on the rotating sleeve 42. One end of the connector 441 is connected to the handle rotating shaft 46, and the other end is connected to the handle 44. The rear end of the pin 45 is movably connected to the handle 44 via a connecting rod 47. One end of the connecting rod 47 is hinged to the rear end of the pin 45 via a pivot, and the other end is hinged to the handle 44 via a pivot. The front end of the pin 45 is configured to correspond to the pin limiting hole in a horizontally movable insertion or withdrawal manner.

[0052] The operation method for adjusting the angle of the bird deterrent cannon using the rotating fixing device of this utility model is as follows: Initially, the pin 45 is inserted into the first pin limiting hole 412, and the cannon mount 2 is at a horizontal angle. Move the handle 44 to the right, and the connecting piece 441 drives the handle rotation shaft 46 to rotate. The connecting rod 47 pulls the pin 45 horizontally, and the pin 45 moves away from the first pin limiting hole 412. Rotate the handle 44 downwards, and the limiting pin 43 slides in the limiting groove 411, causing the cannon mount 2 to rotate around the pivot on the first base 11 and 12. When it moves to the second pin limiting hole 413, move the handle 44 to the left, and the pin 45 moves to the left and inserts into the second pin limiting hole 413, thus fixing the cannon mount 2 at this angle position. In this embodiment, when rotated to the second pin limiting hole 43, the cannon mount and the cannon barrel form an 80° angle with the horizontal. Using the same handle operation method, rotate the pin 45 to the third pin limiting hole 414. When the pin is inserted into the third pin limiting hole, the cannon body of the bird deterrent cannon 3 forms a 100° angle with the horizontal line.

[0053] The handle assembly 4 consists of a pin, an angle limiting plate, a handle rotation shaft, a handle, and a limiting pin. By rotating the handle, the position of the pin inserted into the pin limiting hole on the angle limiting plate is adjusted to regulate the angle of the bird deterrent cannon. The limiting pin always slides within the limiting groove to prevent the bird deterrent cannon from falling. The rotation angle of the bird deterrent cannon can be adjusted at multiple angles according to actual working needs, while also preventing it from falling. The equipment operates stably and is easy to operate.

[0054] Preferably, the rotating sleeve 42 is provided with a mounting frame 422, and the handle rotation shaft 46 is vertically arranged inside the mounting frame 422. The connecting member 441 is an L-shaped connecting rod, with one end sleeved on the handle rotation shaft 46 and the other end connected to the handle 44. With the mounting frame 422, when the handle 44 is turned to the right, the connecting rod moves to the right. The mounting frame 442 limits the horizontal movement of the connecting rod, preventing excessive horizontal movement and thus avoiding the pin 45 from falling off.

[0055] Preferably, the rotating sleeve 42 is fixedly provided with a connecting plate 423, the front end of which is fixedly provided on the rotating sleeve 42, and the rear end of which extends toward the rear end of the first base 11. The rear end of the limiting pin 43 is fixedly connected to the connecting plate 423. The connecting plate 423 is provided with a through pin sleeve 424, the front end of which extends into the pin sleeve 424, and the rear end is movably connected to the handle 44 through a connector 441. With the pin sleeve 424 provided, when the pin 45 moves horizontally and disengages from the pin limiting hole, the pin 45 is placed inside the pin sleeve 424, with its front end located inside the pin sleeve 424 or flush with the front end of the pin sleeve 424. When the pin 45 moves horizontally, it can make the pin 45 move smoothly and along a horizontal straight line, avoiding the pin 45 from falling off during horizontal movement.

[0056] Preferably, the rear end of the rotating sleeve 42 is provided with a sleeve pin retaining plate 425, which is used to fix the rotating shaft 421 and restrict the horizontal rightward movement of the rotating shaft 421.

[0057] Preferably, the rear end face of the gun carriage is provided with a fireproof mechanism 8. The fireproof device 8 includes a mounting base 81 and multiple long partitions 82. The mounting base 81 is located on the rear side of the gun carriage 2, at the end of the gun barrel 3. The mounting base 81 is a rectangular tube structure with two mounting holes 83 in the middle, through which bolts are used to fix it to the gun carriage 2. Multiple long partitions 82 are connected to the mounting base 81. A long partition 82 is provided between two adjacent gun barrels 3. The lower surface of the long partition 82 is attached to the rear side of the gun carriage 2, and the upper surface of the long partition 82 is higher than the end face of the gun barrel 3. The long partitions 82 divide each gun barrel into an independent isolation space. Preferably, each isolation space of the gun barrel 3 is provided with a separate ignition mechanism 5. When igniting to scare away birds, after placing the shell inside the cannon barrel, the shell fuse is attached to the ignition mechanism 4. Then, the rear cover 7 is flipped down and closed, and the sealing gasket 71 is attached to the cannon mount 2, so that the rear cover and the partition 82 form a sealed space to prevent the flames that rush out after the explosion from flying into the shell fuses of other spaces, causing other shells to ignite.

[0058] Preferably, multiple gun barrels 3 are arranged around the gun carriage 2. The mounting base 81 of the fireproof device is located in the middle of the rear side of the gun carriage 2, in the middle of the multiple gun barrels 3. The rear ends of multiple long partitions 82 are located on the mounting base 81, and the front ends extend outward, arranged in a firing pattern. A long partition 82 is provided between two adjacent gun barrels 3. The two adjacent long partitions 82 separate the gun barrels 3 to form an independent isolation space. The arrangement of the gun barrels 3 in a ring makes the distribution of the gun barrels 3 reasonable, and the firing of shells does not affect each other. The firing-patterned long partitions can effectively separate the gun barrels 3 to form independent interval spaces. The overall structure is reasonable and compact.

[0059] Preferably, a baffle 84 is provided at the end of the long partition 82, and the baffle 84 is arranged perpendicular to the long partition 82. The baffle 84 is used to block the gap between two adjacent gun barrels, keep the gap space closed, and prevent the flame from flying into the fuse of the shell of the adjacent gun barrel.

[0060] Preferably, the baffle 84 is detachably connected to the long partition 82. The baffle 82 is provided with a guide groove (not shown), and the long partition 82 is inserted into the guide groove of the baffle 84. The baffle 84 is detachably located at the end of the long partition 82. When the gap between two adjacent barrels 3 is small, the long partition 82 can effectively block the flow of light, and the baffle 84 can be removed.

[0061] Preferably, the rear cover 7 includes a cover body 72 and a locking mechanism 73. The upper end of the cover body 72 is hinged to the upper end of the gun carriage 2. A sealing strip 71 is provided around the inner surface of the cover body 72. The locking mechanism 73 is provided on the cover body 72 for connecting with the gun carriage 2.

[0062] Preferably, the locking mechanism 73 includes a locking hook 731, a push rod 732, and a locking rod 733. The locking hook 731 is mounted on the gun carriage 2 and located on the lower surface of the gun carriage 2. The push rod 732 is rotatably connected to the cover 72. The rear end of the locking rod 733 is rotatably connected to the push rod 732 via a pivot 734, and the front end is a movable end with a hook (not shown). When the rear cover 7 is sealed, the cover 72 is flipped downwards, the sealing strip 71 on the cover is in contact with the gun carriage 2, the locking rod 733 is moved, the hook at the front end of the locking rod 733 is moved to the hook lock 731, the push rod 733 is flipped upwards to lock the rear cover, and the rear cover is sealed.
