Description

Technical Field

[0001] This invention relates to the field of launcher technology, and in particular to a handheld bird deterrent launcher. Background Technology

[0002] Bird control over military or civilian airports is primarily for the purpose of protecting the safety of aircraft takeoffs and landings, preventing birds from being sucked into engines or colliding with the fuselage, landing gear, windshield, etc., during high-speed takeoffs and landings. Using bird control equipment within airport grounds is one of the effective ways to prevent bird strikes. Bird repellent grenades do not harm birds; they use the sound of an explosion to scare them. This is also one of the main methods of bird control at airports. To facilitate the use of bird repellent grenades by staff at airport locations where bird control is needed, the flexibility of bird control areas is improved.

[0003] The existing announcement CN117848160A discloses a handheld bird deterrent launcher. The scheme discloses that it "includes a body, a launch tube, bird deterrent projectiles, and a handle assembly. The handle assembly includes a grip, a protective shell, a rear support, a connecting component, a DC power supply, a first coil, and a control component. After the body and the protective shell are pulled apart in opposite directions, the bird deterrent projectiles are pressed longitudinally into the magazine from the rear top of the body. After the two parts are closed together, the power switch of the DC power supply is turned on, and the firing switch is pressed in the direction of bird deterrence. The high-frequency current passes through the first coil to generate an alternating electromagnetic field. The coil on the bird deterrent projectile close to the first coil receives the alternating magnetic field and converts it into an alternating current. The current is discharged through the parallel ignition head, generating high heat to excite the ignition head inside the bird deterrent projectile, launching the bird deterrent projectile. The sound of the bird deterrent projectile exploding repels birds."

[0004] The aforementioned solutions and existing technologies for gun-type bird deterrent projectile launchers generate noise and smoke pollution while launching the projectiles; the launching chambers used to launch the bird deterrent projectiles lack suitable noise and smoke absorption mechanisms to meet usage requirements.

[0005] Therefore, this invention proposes a handheld bird deterrent launcher to solve the above problems. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-10 A handheld bird deterrent launcher includes a launching chamber body 1 and a launching tube 2 disposed at the front end of the launching chamber body 1; A connecting screw groove 21 is provided inside the front end of the launch tube 2. The connecting screw groove 21 is used to connect the carrying guide tube 3. A mating outer screw ring 32 is provided at one end of the carrying guide tube 3. The mating outer screw ring 32 is threadedly connected to the connecting screw groove 21. Silencing grooves 31 are provided at equal intervals on the side wall of the carrying guide tube 3. A loading fitting 5 is also sleeved on the outer wall of the bearing conduit body 3. An inner protruding ring 501 is provided on the inner wall of one end of the loading fitting 5. The inner protruding ring 501 is sleeved and contacts the outer wall of the bearing conduit body 3 and is fixedly connected by screws. Auxiliary side grooves 503 are also provided at equal intervals on the outer side wall of the loading pipe 5. An auxiliary component is installed in the auxiliary side groove 503. The auxiliary component works in conjunction with the sound-absorbing pipe body 4 to absorb and purify the generated noise and smoke.

[0024] Combined with appendix Figure 1-4 As shown, this solution addresses the noise and smoke generated during the launch of bird deterrent projectiles by using a support conduit 3, a sound-absorbing tube 4, and a loading tube 5 to form an auxiliary mechanism for absorbing and purifying noise and smoke. The support conduit 3 is connected to the launch tube 2 and supports the sound-absorbing tube 4 and the loading tube 5. In other words, the noise and smoke generated are absorbed and purified through the combined use of the sound-absorbing tube 4 and the auxiliary components.

[0025] The sound-absorbing tube 4 initially absorbs the generated noise. The smoke and the noise that escapes pass through the smoke flow hole 401 on the sound-absorbing tube 4, and then pass through the smoke purification cotton ball 606 set inside the loading strip 603 to absorb the noise a second time and purify the smoke.

[0026] In the use of the carrier conduit 3, a docking external threaded ring 32 is fixedly installed at one end of the tube opening. The docking external threaded ring 32 is threadedly connected to the connecting threaded groove 21 on the inner side of the front end of the launch tube 2 to realize the installation of the carrier conduit 3.

[0027] According to the appendix Figure 2 and appendix Figure 7-10 As shown, this solution provides an annular positioning slot 502 on the inner side of the inner protruding ring 501 at one end of the loading pipe 5. The annular positioning slot 502 is adapted to be inserted into one end of the sound-absorbing pipe body 4 to provide a positioning effect for the sound-absorbing pipe body 4.

[0028] For the installation and use of the loading tube 5, before connecting and installing the carrier conduit 3 and the launch tube 2, the loading tube 5 needs to be installed on the carrier conduit 3; directly put the loading tube 5 on the outside of the carrier conduit 3 until the ends of the loading tube 5 and the carrier conduit 3 are aligned, and then fix the loading tube 5 with screws.

[0029] The smoking purification cotton ball 606 installed on the inner side of the loading pipe 5 can be disassembled separately. The auxiliary components include a support strip 601. Mounting protrusions 604 are symmetrically fixed at both ends of the support strip 601. The support strip 601 is adapted to fit into the auxiliary side groove 503 on the loading pipe 5, and the mounting protrusions 604 are in close contact with the outer wall of the loading pipe 5, and then fixed with screws. A strip-shaped heat dissipation groove 602 is also provided along the length of the support strip 601 to provide heat dissipation. The support strip 601 is fitted into the auxiliary side groove 503 on the side of the loading pipe 5, and then fixed to the loading pipe 5 by screws through the mounting protrusions 604 at both ends of the support strip 601, allowing the support strip 601 to be disassembled for easy disassembly, assembly, and maintenance.

[0030] From the appendix Figure 9-10 As shown, this solution includes a loading strip 603 fixedly installed along the length of the strip-shaped heat dissipation groove 602. The loading strip 603 is used to install the smoke purification cotton ball 606. A connecting clip 605 is also fixedly installed on the inner side wall of the loading strip 603. The connecting clip 605 is arranged in a straight line at equal intervals. The connecting clip 605 is used to connect the smoke purification cotton ball 606. Auxiliary mesh bodies 607 are evenly arranged in the smoke purification cotton ball 606 to provide auxiliary effects for eliminating and purifying smoke and noise. A connecting slot 608 that is adapted to and engages with the connecting clip 605 is also provided on the smoke purification cotton ball 606 to facilitate the installation and removal of the smoke purification cotton ball 606.

[0031] The use of the smoke purification cotton ball 606 involves uniformly setting auxiliary mesh 607 on its spherical sidewall. On the one hand, it has an auxiliary effect on noise absorption, and on the other hand, it can also provide a collection effect for particles in the smoke when absorbing and purifying the smoke.

[0032] Furthermore, the smoking purification cotton ball 606 is installed by the connection between the connecting slot 608 and the connecting head 605, which allows the smoking purification cotton ball 606 to be disassembled individually and the smoking purification cotton ball 606 to be replaced and maintained in a later stage, which is highly flexible in operation.

[0033] Then from the appendix Figure 7-10As shown, the smoking purification cotton balls 606 in this solution are installed on the inner side of the loading strip 603 by the connection of the connecting slot 608 and the connecting head 605, and are arranged in a straight line at equal intervals. That is, multiple smoking purification cotton balls 606 are arranged in a straight line at equal intervals on the inner side of the loading strip 603. Since the bearing strip 601 is arranged at equal intervals on the side wall of the loading tube 5, and is arranged in a ring at equal intervals, the straight-line smoking purification cotton balls 606 arranged at equal intervals are also arranged in a ring at equal intervals on the inner side of the loading tube 5. Therefore, it can be seen that the smoking purification cotton balls 606 are located in the loading cavity formed between the loading tube 5 and the bearing guide tube 3.

[0034] From the appendix Figure 2-3 and appendix Figure 8 As shown, this solution has a through groove in the inner convex ring 501 on the inner side of one end of the loading pipe 5. When using screws for fixing, the screws are inserted into the through groove and then threadedly connected to the corresponding screw groove on the outer side wall of the bearing conduit 3, thereby realizing the installation of the loading pipe 5.

[0035] Combined with the appendix Figure 2 and appendix Figure 4-6 As shown, after the loading tube 5 is installed on the outside of the bearing guide tube 3, since an inner protruding ring 501 is provided on the inner side of one end of the loading tube 5, and the inner protruding ring 501 contacts the bearing guide tube 3, a space is formed between the loading tube 5 and the bearing guide tube 3. That is, a loading cavity is formed between the inner wall of the loading tube 5 and the outer wall of the bearing guide tube 3. A sound-absorbing tube 4 is installed in the loading cavity, and the sound-absorbing tube 4 is used to absorb the noise generated by the launch of bird deterrent projectiles.

[0036] That is, after the loading pipe 5 is installed and fixed, the sound-absorbing pipe 4 is installed, that is, the sound-absorbing pipe 4 is inserted into the loading cavity formed between the loading pipe 5 and the bearing conduit 3.

[0037] The sound-absorbing pipe body 4 has uniformly arranged flue gas flow holes 401 on its side wall, which are used to facilitate the flow of generated flue gas. An installation groove 402 is also provided on the outer side wall of the sound-absorbing pipe body 4. The installation groove 402 is equidistantly arranged, and auxiliary strips 403 are uniformly arranged in the installation groove 402. Fine mesh 404 is also provided in the auxiliary strips 403, which, along with the fine mesh 404, provide auxiliary effects for noise absorption. A loading ring 405 is also fixedly provided at one end of the sound-absorbing pipe body 4. The loading ring 405 is inserted into the cavity formed by the inner side wall of the loading pipe 5 and the outer side wall of the bearing guide tube 3.

[0038] Insert one end of the sound-absorbing tube 4 into the opening of the loading cavity, that is, the end of the loading tube 5 without the inner convex ring 501. While inserting the sound-absorbing tube 4 into the loading cavity, the auxiliary strip 403 on the sound-absorbing tube 4 needs to be offset from the smoking purification cotton ball 606 on the inside of the loading tube 5 until the opening of one end of the sound-absorbing tube 4 is inserted into the annular positioning slot 502 on the inside of the inner convex ring 501. At the same time, the loading insertion ring 405 on the other end of the sound-absorbing tube 4 will be inserted back into the loading cavity, that is, the opening of the loading cavity is sealed. That is, the inner wall of the loading insertion ring 405 is in close contact with the outer wall of the carrying guide tube 3, and the outer wall of the loading insertion ring 405 is in close contact with the inner wall of the loading tube 5. The installation of the sound-absorbing tube 4 is then completed.

[0039] Limiting stops 406 are also provided at equal intervals on the outer side wall of the end of the loading ring 405. The limiting stops 406 are used to limit the loading ring 405 and facilitate the disassembly of the sound-absorbing tube 4. That is, when the sound-absorbing tube 4 needs to be pulled out of the loading cavity later, the limiting stops 406 make it easier to pull out the sound-absorbing tube 4.

[0040] Combined with the appendix Figure 2 As shown in 4-6, when it is necessary to disassemble, replace or clean the sound-absorbing tube body 4, it can be disassembled separately. That is, by holding the limit stop 406 on the loading ring 405 with your hand, slowly pull the loading ring 405 out of the loading cavity. After the loading cavity is separated from the loading cavity, the sound-absorbing tube body 4 can be pulled out of the loading cavity. The disassembly of the sound-absorbing tube body 4 can be completed quickly.

[0041] During this process, due to the adhesion of angular impurities to the surface of the smoking purification cotton ball 606 after long-term use, the sound-absorbing tube 4 can be rotated during the extraction of the sound-absorbing tube body 4 from the loading cavity. The rotating sound-absorbing tube body 4 will cause the auxiliary strip 403 on the mounting groove 402 to come into contact with the smoking purification cotton ball 606. At this time, the auxiliary strip 403 is equivalent to a cleaning strip, that is, it provides a patting effect on the smoking purification cotton ball 606 to provide a simple cleaning effect.

[0042] Finally, from the appendix Figure 7-10 As shown, when it is necessary to completely disassemble, clean, or replace the smoking purification cotton balls 606; The loading fitting 5 can be completely disassembled, that is, the fixed connection between the loading fitting 5 and the bearing conduit 3 can be released, that is, the fixed connection between the inner protruding ring 501 on the inner side of one end of the loading fitting 5 and the bearing conduit 3 can be released. Then the loading fitting 5 can be pulled out and removed from the bearing conduit 3. Then each smoke purification cotton ball 606 can be pulled out one by one, that is, the connection between the connecting clip 605 and the connecting slot 608 can be released. The disassembly of the smoke purification cotton ball 606 can then be completed. After that, the smoke purification cotton ball 606 can be cleaned or a new smoke purification cotton ball 606 can be replaced and then installed on the connecting clip 605.

[0043] Similarly, instead of completely disassembling the loading tube 5, the support strips 601 used to load the smoking purification cotton balls 606 can be removed one by one, that is, the position fixation of the support strips 601 can be released. Then, the support strips 601 can be removed from the auxiliary side grooves 503 on the loading tube 5. Then, the support strips 601 in the remaining positions can be removed.

[0044] After removing the support strip 601, the smoke purification cotton balls 606 can be removed and replaced one by one, or cleaned. Similarly, when it is necessary to replace the smoke purification cotton balls 606 in a certain position, simply remove the support strip 601 of the corresponding position from the loading pipe 5, and then disassemble, replace or clean the smoke purification cotton balls 606. The operation is highly flexible.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
