Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone countermeasures, and more specifically to a drone countermeasure detection and alarm device. Background Technology
[0002] Drone countermeasures technology refers to the use of various technical means to detect, identify, interfere with, and destroy illegally intruding drones, thereby eliminating drone threats and ensuring the safety of people and property.
[0003] Currently, when detecting and alerting drones, the general method is to use detection radar to emit signals and receive reflections. Once a drone is detected, an alarm is issued. However, most of the detection radars equipped with existing alarm devices can only emit signals in one direction, resulting in a limited detection range. Utility Model Content
[0004] This invention provides a drone countermeasure detection and alarm device that can detect all surrounding areas.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A drone countermeasure detection and alarm device includes an audible alarm and a support plate. The alarm is installed at the center of the support plate. The support plate has three mounting holes evenly distributed around its circumference, and a detection radar is installed in each of the three mounting holes. A central shaft is fixed at the center of the lower end face of the support plate, and the lower end of the central shaft rotates on the base plate.
[0007] The lower end of the detection radar is fixed with a worm gear seat that rotates in the mounting hole. Three worm shafts rotate on the lower end face of the support plate, and the three worm shafts are respectively meshed with and connected to the three worm gear seats for transmission.
[0008] A conical wheel is fixed at the center of the base plate, and the conical wheel is simultaneously engaged with three worm shafts for transmission.
[0009] The cone surface of the cone wheel is uniformly provided with three meshing teeth for meshing and transmission with the worm shaft.
[0010] The bottom of the base plate is provided with multiple support legs.
[0011] A protective cover is provided between the tray and the base plate.
[0012] A storage battery is installed on the tray.
[0013] The alarm can emit lights when it sounds an alarm.
[0014] The alarm emits a flashing light.
[0015] The alarm is hemispherical in shape.
[0016] The beneficial effects of this utility model are:
[0017] The three detection radars rotate around the central axis, transmitting detection signals in all directions to achieve full coverage detection in all directions.
[0018] The rotation of the worm shaft meshes with the worm gear seat, causing the detection radar to rotate around the axis of the worm gear seat, thereby changing the signal transmission direction in the vertical plane. Attached Figure Description

[0028] 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.
[0029] like Figure 1-6 As shown:
[0030] A drone countermeasure detection and alarm device includes an alarm 1 capable of emitting sound and a support plate 2. The alarm 1 is installed at the center of the support plate 2. The support plate 2 has three mounting holes 3 evenly distributed around its circumference. A detection radar 9 is installed in each of the three mounting holes 3. A central shaft 4 is fixed at the center of the lower end face of the support plate 2. The lower end of the central shaft 4 rotates on a base plate 6.
[0031] Three detection radars 9 are evenly arranged around the perimeter to form a signal detection range in the perimeter. At the same time, the transmission central shaft 4 drives the support plate 2 to rotate, which in turn causes the three detection radars 9 to rotate around the central shaft 4, thereby transmitting detection signals in the four directions and achieving full coverage detection in all directions.
[0032] When a drone is detected, alarm 1 sounds an alarm.
[0033] Further:
[0034] The lower end of the detection radar 9 is fixed with a worm gear seat 8 that rotates in the mounting hole 3. The lower end face of the support plate 2 has three worm shafts 10 that rotate, and the three worm shafts 10 are respectively meshed with and connected to the three worm gear seats 8 for transmission.
[0035] By rotating the worm shaft 10, the worm gear seat 8 can be engaged and rotated, thereby causing the detection radar 9 to rotate around the axis of the worm gear seat 8, thus changing the signal transmission direction in the vertical plane.
[0036] Further:
[0037] A conical wheel 7 is fixed at the center of the base plate 6, and the conical wheel 7 is simultaneously engaged with three worm shafts 10 for transmission.
[0038] When the transmission center shaft 4 drives the support plate 2 to rotate, it enables the worm shaft 10 and the conical wheel 7 to move relative to each other. This causes the worm wheel seat 8 to rotate around the center shaft 4 and also rotate around its own axis. As a result, the detection radar 9 can transmit signals circumferentially around the center shaft 4 and also rotate around the axis of the worm wheel seat 8 to transmit signals vertically, thereby further expanding the detection range.
[0039] Further:
[0040] The cone wheel 7 has three meshing teeth evenly arranged on its conical surface for meshing and transmission connection with the worm shaft 10.
[0041] Each time the worm shaft 10 rotates to one of the meshing teeth on the conical wheel 7, a rotation occurs, resulting in a change in the orientation of the detection radar 9 in the vertical direction. This causes the detection radar 9 to turn slightly in the vertical direction, ensuring full circumferential coverage by the three detection radars 9.
[0042] To prevent the worm shaft 10 and the conical wheel 7 from constantly meshing and transmitting power, the detection radar 9 should not rotate too quickly in the vertical direction, which would affect the overall coverage.
[0043] like Figure 2-5 As shown:
[0044] The lower end of the base plate 6 is provided with multiple support legs.
[0045] This facilitates the installation of the first motor at the lower end of the base plate 6 to drive the central shaft 4 and make the detection radar 9 rotate. The first motor operates in a timed reciprocating manner, that is, after rotating clockwise for a certain period of time, it rotates counterclockwise for a certain period of time, and so on, to avoid the detection radar 9 from being tightly stuck to the edge of the mounting hole 3.
[0046] Further:
[0047] By providing a protective cover 11 between the pallet 2 and the base plate 6, the transmission part between the pallet 2 and the base plate 6 is protected.
[0048] Further:
[0049] The alarm 1 and the detection radar 9 are powered by a battery 5 installed on the tray 2.
[0050] Further:
[0051] The alarm 1 can emit light when it sounds an alarm.
[0052] The alarm 1 is set to emit flashing lights.
[0053] It makes it easier for staff to spot.
[0054] Further:
[0055] By setting the alarm 1 in a hemispherical shape, the device is made more aesthetically pleasing while avoiding the alarm 1 from interfering with the operation of the detection radar 9.
[0056] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
