Description

Technical Field

[0001] This utility model relates to the field of drone interception technology, specifically a drone catapult interception net launching device. Background Technology

[0002] Drone interception refers to capturing, controlling, or destroying drones through technical means to eliminate potential security threats. For example, it involves using specially designed nets to capture and secure drones. This method is suitable for small drones, has a high success rate, and is relatively inexpensive. However, when the drone interception net is ejected from the device, it passively spreads only by the initial impact force during ejection. Since the direction of the ejection force is mostly straight forward, the interception net cannot effectively deploy in the air, and the interception area is smaller than expected, which may result in interception failure.

[0003] Therefore, this utility model provides a drone catapult interception net launching device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this embodiment provides a technical solution: a drone catapult interceptor launcher, including a mounting base 1, a housing 2 fixedly connected to the upper part of the mounting base 1, a rotating pipe 3 fixedly connected to the upper end of the housing 2, the inner circumference of the housing 2 being equal to the outer circumference of the push platform 4, the housing 2 and the push platform 4 being adapted to each other, a rotating mechanism being provided inside the rotating pipe 3, the rotating mechanism including the push platform 4, a turntable 5, a ball bearing 6 and a threaded groove 7, the bottom of the turntable 5 being rotatably connected to the push platform 4, the turntable 5 being adapted to the push platform 4, the surface of the turntable 5 being slidably connected to the rotating pipe 3, the inner circumference of the turntable 5 being equal to the outer circumference of the push platform 4 ... The outer periphery of the rotating pipe 3, the surface of the rotating ball 6 fits against the turntable 5, and the threaded groove 7 is set on the inner wall of the rotating pipe 3. The rotating ball 6 is rolled between the rotating pipe 3 and the threaded groove 7. The rotating ball 6 and the threaded groove 7 are adapted to each other. When the pusher 4 pushes the turntable 5 to slide out of the rotating pipe 3, the rotating ball 6 moves with the turntable 5. Under the restriction of the threaded groove 7, the rotating ball 6 drives the turntable 5 to rotate, so that the interception net placed on the turntable 5 rotates before launch. This causes it to quickly spread out in all directions in the air due to the centrifugal force, increasing the interception area and achieving a better interception effect.

[0024] like Figures 1-3As shown: A motor 8 is fixedly connected inside the housing 2, and a drive bevel gear 9 is fixedly connected to the output end of the motor 8. When the motor 8 is started, the output end of the motor 8 drives the drive bevel gear 9 to rotate inside the housing 2.

[0025] like Figures 1-3 As shown: A rotating frame 10 is fixedly connected to the inner wall of the outer shell 2. A rotating cylinder 11 is rotatably connected to the surface of the rotating frame 10. The inner circumference of the rotating frame 10 is equal to the outer circumference of the rotating cylinder 11. A driven bevel gear 12 is fixedly connected to the side end of the rotating cylinder 11. The surface of the driven bevel gear 12 meshes with the driving bevel gear 9. The driven bevel gear 12 and the driving bevel gear 9 are adapted to each other. When the driving bevel gear 9 rotates, it drives the driven bevel gear 12 to rotate, thereby causing the rotating cylinder 11 to rotate on the rotating frame 10.

[0026] like Figures 1-3 As shown: A cable 13 is fixedly connected to the surface of the rotating drum 11. The end of the cable 13 is fixedly connected to the push platform 4. The cable 13 can pull the push platform 4 to move. A spring 14 is fixedly connected to the bottom of the push platform 4. The fixed end of the spring 14 is fixedly connected to the outer shell 2. A top cover 15 is threadedly connected to the end surface of the rotating pipe 3. The rotating pipe 3 and the top cover 15 are compatible. When the rotating drum 11 is rotated, the cable 13 can be wound around the surface of the rotating drum 11 to pull the push platform 4 back. Under the push of the spring 14, the push platform 4 can be quickly ejected.

[0027] like Figures 3-4 As shown: An elastic steel plate 16 is fixedly connected to the inner wall of the outer shell 2. A slide table 17 is fixedly connected to the side end of the elastic steel plate 16. A first clamping head 18 is fixedly connected to the side end of the slide table 17. When the first clamping head 18 is squeezed, it pushes the elastic steel plate 16 to deform, thereby allowing the slide table 17 to move to both sides. Under the push of the elastic steel plate 16, the slide table 17 can drive the first clamping head 18 to move inward.

[0028] like Figures 3-4 As shown: A second locking head 19 is slidably connected to the side end of the slide table 17. A slot 20 is provided on the surface of the push table 4. The second locking head 19 is slidably connected to the push table 4 through the slot 20. When the bottom end of the push table 4 presses the first locking head 18, the first locking head 18 moves to both sides. When the bottom end of the push table 4 contacts the second locking head 19, it pushes the second locking head 19 to slide downward on the slide table 17. At the same time, the first locking head 18 pops out under the push of the slide table 17 and inserts into the slot 20 to lock it. When the push table 4 continues to press downward, the second locking head 19 cannot continue to slide downward on the slide table 17, thus forcing the slide table 17 to move to both sides and inserting the second locking head 19 into the slot 20. This is the downward pulling force of the push table 4. The push table 4 pops out upward under the push of the spring 14, thus pressing the second locking head 19 to slide to both sides again, completing the unlocking effect of the push table 4.

[0029] like Figures 3-4As shown: The surface of the turntable 5 is hinged to a limiting plate 21, and the surface of the limiting plate 21 is fitted with balls 22. The diameter of the balls 22 is much larger than the pitch of the threaded groove 7, so that the balls 22 will not be inserted into the threaded groove 7. The surface of the balls 22 is in rolling connection with the rotating pipe 3. The counterweight of the interception net is inserted into the groove of the turntable 5, and the interception net is placed in the turntable 5. When the cable 13 is pulled, the limiting plate 21 rotates to position the interception net in the turntable 5, realizing the quick installation of the interception net and improving the reusability of the device. When the turntable 5 is ejected, the limiting plate 21 rotates outward, so that the interception net opens and is ejected.

[0030] Working principle: like Figures 1-4 As shown: In use: Insert the counterweight of the interception net into the slot of the turntable 5, and place the interception net inside the turntable 5. When the cable 13 is pulled, the limit plate 21 rotates to position the interception net inside the turntable 5, realizing the quick installation of the interception net and improving the reusability of the device. When the turntable 5 is ejected, the limit plate 21 rotates outward, causing the interception net to open and be ejected. When the pusher 4 pushes the turntable 5 to slide from the rotating pipe 3, the rotating ball 6 moves with the turntable 5. Under the restriction of the threaded groove 7, the rotating ball 6 drives the turntable 5 to rotate, so that the interception net placed on the turntable 5 rotates before launch, so that it can quickly spread outwards in the air due to the centrifugal force, increasing the interception area and achieving a better interception effect. When the bottom of the pusher 4 contacts the second locking head 19, it pushes the second locking head 19 to slide downward on the slide 17. At the same time, the first locking head 18 is pushed out by the slide 17 and inserted into the slot 20 to lock it. When the pusher 4 continues to press down, the second locking head 19 can no longer slide downward on the slide 17, thus forcing the slide 17 to move to both sides, so that the second locking head 19 is inserted into the slot 20. This is the downward pulling force of the pusher 4. The pusher 4 is pushed upward by the spring 14, thus squeezing the second locking head 19 to slide to both sides again, completing the unlocking effect of the pusher 4.
