Description

Technical Field

[0001] This utility model relates to the field of drone countermeasures technology, specifically to a low-altitude drone detection and countermeasure device. Background Technology

[0002] Existing drone countermeasure technologies can be broadly categorized into three types. The first type involves interference and disruption, primarily achieved through signal jamming and acoustic interference. The second type involves direct destruction, including the use of bullets, laser weapons, missiles, and drones to counter drones. The third type involves monitoring and control, mainly achieved through methods such as hijacking radio control. The process of countering drones can be divided into two main phases: detection and attack. First, the target drone needs to be detected, tracked, and given early warning. Then, appropriate destructive measures are taken based on the actual situation. In the process of interfering with and disrupting drone flight, technologies such as radar detection, photoelectric identification, and radio spectrum analysis are largely utilized. Radar detection technology uses the transmission and reception of electromagnetic waves to detect the drone's position and movement, while signal jammer technology transmits electromagnetic waves with the same frequency and modulation as the drone's communication signals, preventing the drone from communicating and controlling normally.

[0003] Most of the countermeasures used to interfere with and block the flight of drones are located outdoors, and these countermeasures need to be at a certain height for detection. However, due to the uncertainty of the outdoor environment, the frame and equipment are easily affected by rain, strong winds and other severe weather conditions during long-term operation. Based on this, this solution provides a low-altitude drone detection and countermeasure device to solve the above-mentioned problems. Utility Model Content

Bevel gear one meshes with bevel gear two, which is fixedly mounted on the threaded rod.

Several sets of telescopic rods are fixedly connected between the lifting plate and the fixed box. Synchronization assembly one and synchronization assembly two are meshed on both sides of bevel gear two, respectively, and are used to drive the left and right protective boxes to slide. A locking element is provided at the bottom of the threaded rod.

[0007] Preferably, the structures of synchronization component one and synchronization component two are exactly the same, and they are rotated 180 degrees about the central axis of the threaded rod.

[0008] Preferably, the synchronization component one includes a bevel gear three that meshes with bevel gear two. A rotating shaft is fixedly connected to bevel gear three.

[0010] Preferably, the locking component includes a locking block fixedly connected to the threaded rod, the locking block having several sets of locking grooves, a fixing seat fixedly mounted on the fixing box on the left side of the locking block, a plug rod slidably connected inside the fixing seat, the right end of the plug rod matching the locking groove, and a guide plate fixedly connected to the right side surface of the plug rod, a fixing groove for sliding with the guide plate being provided at the bottom of the fixing box, and a spring sleeved on the plug rod being fixedly connected between the guide plate and the fixing seat.

[0011] Preferably, a slidable L-shaped plate is provided on the left side of the fixed base, and a sliding seat for sliding with the L-shaped plate is fixedly connected to the bottom of the fixed box.

[0012] Compared with the prior art, this utility model proposes a low-altitude unmanned aerial vehicle (UAV) detection and countermeasure device, which has the following beneficial effects:

[0013] 1. This utility model includes a lifting assembly. When the countermeasure radar is in operation, it is driven by a servo motor in the lifting assembly. Through the transmission of bevel gear one and bevel gear two, the threaded rod rotates. After the threaded rod rotates, it drives the sleeve to lift the lifting plate upward, thus lifting the countermeasure radar. At the same time, bevel gear two synchronously drives synchronization components one and two on both sides. Synchronization components one and two drive the left and right protective boxes to slide open, making it easier for the lifting plate to lift the countermeasure radar upward, thus allowing the countermeasure radar to be used better. When the external environment is not suitable for the countermeasure radar to be exposed to the outside, the servo motor reverses, thereby driving the threaded rod to rotate in the opposite direction, so that all parts are reset, thus storing and resetting the countermeasure radar. Synchronization components one and two drive the left and right protective boxes to close, thus protecting the countermeasure radar after it is stored, and preventing rain, strong winds and other severe weather from affecting the countermeasure equipment.

Detailed Implementation

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-6 As shown, a low-altitude unmanned aerial vehicle (UAV) detection and countermeasure device includes a fixed box 1, a guide seat 2 fixedly mounted on the fixed box 1, and a left protective box 3 and a right protective box 4 with identical structures slidably connected to the guide seat 2. A lifting plate 5 is provided inside the left and right protective boxes 3 and 4, and a countermeasure radar 6 is fixedly mounted on the lifting plate 5. A lifting assembly 7 for driving the lifting plate 5 is provided inside the fixed box 1. The lifting assembly 7 includes a threaded rod 701 rotatably mounted on the bottom of the fixed box 1, and a servo motor 702 fixedly mounted on the bottom of the fixed box 1 on one side of the threaded rod 701. The output shaft of the servo motor 702 is fixedly mounted on the bottom of the fixed box 1. A bevel gear 703 is fixedly connected, and a bevel gear 704 is meshed with the bevel gear 703. The bevel gear 704 is fixedly installed on the threaded rod 701. A sleeve 705 is threadedly connected to the upper end of the threaded rod 701. The sleeve 705 is fixedly installed at the lower end of the lifting plate 5. Several sets of telescopic rods 706 are fixedly connected between the lifting plate 5 and the fixed box 1. Synchronization component 8 and synchronization component 9 are meshed with the two sides of the bevel gear 704 respectively. Synchronization component 8 and synchronization component 9 are used to drive the left protective box 3 and the right protective box 4 to slide. A locking component 10 is provided at the bottom of the threaded rod 701.

[0024] Furthermore: When the countermeasure radar 6 is working, it is driven by the servo motor 702 in the lifting assembly 7. Through the transmission of bevel gear 1 703 and bevel gear 2 704, the threaded rod 701 is driven to rotate. After the threaded rod 701 rotates, it drives the sleeve 705 to move the lifting plate 5 upward, thereby moving the countermeasure radar 6 upward. At the same time, bevel gear 2 704 synchronously drives the synchronization assemblies 1 8 and 2 9 on both sides. Through the synchronization assemblies 1 8 and 2 9, the left protective box 3 and the right protective box 4 are driven, thus facilitating the lifting plate 5 to move the countermeasure radar 6 upward, thereby enabling the countermeasure radar 6 to... For better use, a locking component 10 is provided to fix the threaded rod 701, ensuring that the lifting plate 5 and the countermeasure radar 6 can be stably stopped at a high position. When the external environment is not suitable for the countermeasure radar 6 to work in the outside, the servo motor 702 reverses, thereby driving the threaded rod 701 to rotate in the opposite direction, so that all parts are reset, thereby storing and resetting the countermeasure radar 6. The left protective box 3 and the right protective box 4 are driven to close by the synchronization component 1 8 and the synchronization component 2 9, thereby protecting the countermeasure radar 6 after it is stored and avoiding the impact of rain, strong winds and other severe weather on the countermeasure equipment.

[0025] Specifically, in this embodiment, the structures of synchronization component 8 and synchronization component 9 are completely identical, and they are rotated 180 degrees about the central axis of the threaded rod 701.

[0026] Specifically, in this embodiment, the synchronization component 8 includes a bevel gear 803 that meshes with a bevel gear 704. A rotating shaft 802 is fixedly connected to the bevel gear 803. A fixed frame 801 is fixedly mounted on the bottom of the fixed box 1 on one side of the rotating shaft 802. One end of the rotating shaft 802 passes through the fixed frame 801 and is rotatably connected to the inner wall of the fixed box 1. A gear 804 is fixedly connected to the rotating shaft 802. A rack 805 is meshed with the lower end of the gear 804. A guide rail 806 is fixedly mounted on the fixed box 1 on the lower side of the rack 805. The rack 805 is slidably connected to the guide rail 806. A driving component is fixedly connected to the left end of the rack 805.

[0027] Specifically, in this embodiment, the driving component includes a fixed rod 807 fixedly connected to the rack 805. The left end of the fixed rod 807 penetrates the side wall of the fixed box 1 and is fixedly connected to a movable plate 808. Two sets of limiting rods 809 are fixedly connected to the movable plate 808. One end of the limiting rod 809 penetrates into the interior of the fixed box 1 and is fixedly connected to a limiting plate. A connecting rod 8010 is fixedly connected to the outer end of the movable plate 808. The upper ends of the connecting rods 8010 are all fixedly connected to the left protective box 3.

[0028] Furthermore: When the threaded rod 701 rotates, it drives the bevel gear 803 in the synchronization assembly 8 via the second bevel gear 704. The third bevel gear 803 then drives the gear 804 via the rotating shaft 802. The gear 804 then drives the lower rack 805 to slide. The sliding of the rack 805 then drives the outer movable plate 808 to move via the fixed rod 807. During the movement of the movable plate 808, it drives the corresponding left protective box 3 to slide open via the connecting rod 809, preventing the left protective box 3 from blocking the upward movement of the countermeasure radar 6. During the upward movement, the movable plate 808 is stable and does not deviate through the cooperation of two sets of limiting rods 809 and limiting plates, ensuring the overall stability. The working principle of the second synchronization assembly 9 is the same as that of the first synchronization assembly 8, and will not be described again here.

[0029] Specifically, in this embodiment, the locking member 10 includes a locking block 1001 fixedly connected to the threaded rod 701. The locking block 1001 has several sets of locking grooves 1002. A fixing seat 1003 fixedly installed on the fixing box 1 is provided on the left side of the locking block 1001. A plug rod 1004 is slidably connected in the fixing seat 1003. The right end of the plug rod 1004 matches the locking groove 1002. A guide plate 1006 is fixedly connected to the right side surface of the plug rod 1004. A fixing groove 101 for sliding with the guide plate 1006 is provided at the bottom of the fixing box 1. A spring 1005 sleeved on the plug rod 1004 is fixedly connected between the guide plate 1006 and the fixing seat 1003.

[0030] Specifically, in this embodiment, a slidable L-shaped plate 1007 is provided on the left side of the fixed base 1003, and a sliding seat 102 for sliding with the L-shaped plate 1007 is fixedly connected to the bottom of the fixed box 1. An electric push rod 1009 is fixedly installed on the left side of the L-shaped plate 1007 and is fixedly connected to the L-shaped plate 1007. A through groove is provided on the L-shaped plate 1007 for sliding with the insertion rod 1004. A pressing block 1008 is fixedly installed on one side of the through groove and is used to limit the fixed base 1003.

[0031] Furthermore: When the countermeasure radar 6 is working, it is driven by the servo motor 702 in the lifting assembly 7. Through the transmission of bevel gear 1 703 and bevel gear 2 704, the threaded rod 701 is driven to rotate. After the threaded rod 701 rotates, it drives the sleeve 705 to move the lifting plate 5 upward, thereby moving the countermeasure radar 6 upward. During the upward movement, the threaded rod 701 drives the locking block 1001 to rotate as well. During the rotation of the locking block 1001, the insertion rod 1004 repeatedly inserts into and exits the locking groove 1002. Once in place, the insertion rod 1004 is reinserted into the locking groove 1002. The L-shaped plate 1007 is moved by the electric push rod 1009, causing the L-shaped plate 1007 to move the pressing plate 1008 to one end of the insertion rod 1004. This causes the pressing plate 1008 to abut against the insertion rod 1004, thereby limiting the insertion rod 1004 by the L-shaped plate 1007 and limiting the locking block 1001 by the insertion rod 1004. This, in turn, fixes the threaded rod 701, ensuring that the lifting plate 5 and the countermeasure radar 6 can remain stably at a high position.

[0032] The working principle of this utility model is as follows: When the countermeasure radar 6 is working, it is driven by the servo motor 702 in the lifting assembly 7. Through the transmission of bevel gear 1 703 and bevel gear 2 704, the threaded rod 701 is driven to rotate. After the threaded rod 701 rotates, it drives the sleeve 705 to move the lifting plate 5 upward, thereby moving the countermeasure radar 6 upward. At the same time, bevel gear 2 704 synchronously drives the synchronization assemblies 1 8 and 2 9 on both sides: that is, when the threaded rod 701 rotates, bevel gear 2 704 drives bevel gear 3 803 in synchronization assembly 1 8. Bevel gear 3 803 then drives gear 804 through the rotating shaft 802. Gear 804 then drives the rack 805 on the lower side to slide. The sliding of rack 805 then drives the outer moving plate 808 to move through the fixed rod 807. The moving plate 808 moves... During the process, the connecting rod 809 drives the corresponding left protective box 3 to slide open, preventing the left protective box 3 from blocking the upward movement of the countermeasure radar 6. This facilitates the lifting plate 5 to move the countermeasure radar 6 upward, allowing the countermeasure radar 6 to be used better. A locking component 10 is provided to fix the threaded rod 701, ensuring that the lifting plate 5 and the countermeasure radar 6 can be stably stopped at a high position. When the external environment is not suitable for the countermeasure radar 6 to be exposed to the outside, the servo motor 702 reverses, thereby driving the threaded rod 701 to rotate in the opposite direction, so that all parts are reset, thereby storing and resetting the countermeasure radar 6. The left protective box 3 and the right protective box 4 are driven to close by the synchronization component 1 8 and the synchronization component 2 9, thereby protecting the stored countermeasure radar 6 and preventing the countermeasure equipment from being affected by rain, strong winds and other severe weather conditions.
