[0035] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

The first feature being "below", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0038] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] As Figures 1 to 3 shown, the embodiment of the present utility model provides an unmanned aerial vehicle (UAV) countermeasure device, which can achieve the purpose of countering UAVs in the airspace. In some embodiments, the UAV countermeasure device includes a base 1, a fixed shaft 2, a fixing member 31, an antenna assembly 4 and a driving assembly 5. The fixed shaft 2 is arranged on the base 1, and the fixing member 31 is rotatably arranged on the fixed shaft 2; the antenna assembly 4 is arranged on the fixing member 31; the driving assembly 5 is used to drive the fixing member 31 to rotate around the fixed shaft 2 so that the antenna assembly 4 rotates 360°.

[0040] The driving assembly 5 can drive the fixing member 31 to rotate around the fixed shaft 2 to drive the antenna assembly 4 to rotate 360°, so that the UAV countermeasure device can perform countermeasures in multiple directions. When performing countermeasures in multiple directions, there is no need to set up multiple UAV countermeasure devices along multiple directions, effectively reducing the cost and improving the utilization rate of the device.

[0041] Specifically, the driving assembly 5 includes a driving member 51, a conveyor belt 52, and a gear 53. The driving member 51 is fixedly connected to the fixing member 31. The gear 53 is sleeved on the fixed shaft 2 and can rotate around the axis of the fixed shaft 2. One end of the conveyor belt 52 is drivingly connected to the output end of the driving member 51, and the other end is drivingly connected to the gear 53 along the circumferential direction of the gear 53. The rotation of the output end of the driving member 51 drives the conveyor belt to rotate, and the rotation of the conveyor belt drives the gear 53 to rotate. By using the gear ratio of the gear 53 and the fact that the driving member 51 is fixedly arranged on the fixing member 31, the fixing member 31 can rotate slowly, so that the antenna assembly 4 on the fixing member 31 rotates slowly, thereby enabling the UAV countermeasure device to slowly strike UAVs in a 360-degree airspace. The gear 53 serves to convert the relatively fast rotational speed output by the driving member 51 into a relatively slow rotational speed. In this embodiment, the driving member 51 is a servo motor, and the servo motor ensures stable operation and does not exhibit the stepping phenomenon similar to that of a stepper motor. This characteristic makes it perform excellently in occasions requiring high-speed response. Its dynamic response time for acceleration and deceleration is extremely short, usually reaching the predetermined target within dozens of milliseconds, driving the antenna assembly 4 to rotate to achieve 360-degree omnidirectional strike.

[0042] The antenna assembly 4 includes a support member 41, a connecting member 42, and a plurality of antenna bodies 43. The plurality of antenna bodies 43 are arranged on the support member 41, and the support member 41 is arranged above the fixing member 31 through the connecting member 42. This arrangement reduces the interference received by the antenna bodies 43, thereby making the strike effect more accurate. In this embodiment, the connecting member 42 is a connecting rod, and a plurality of connecting members 42 are provided. The arrangement of the plurality of connecting members 42 enables the plurality of antenna bodies 43 to be arranged on the fixing member 31 more stably.

[0043] Furthermore, when the plurality of antenna bodies 43 are arranged in an array on the support member 41, according to actual requirements, they can be arranged in a rectangular array or a circular array. By adopting the installation method of arranging the plurality of antenna bodies 43 in an array, several identical antennas are arranged in a certain pattern to form a system. The main purpose of this array is to enhance the directivity of the antenna and improve the gain by combining multiple antenna elements, thereby improving the communication quality or expanding the signal coverage area.

[0044] To facilitate the rotation of the fixing member 31, the fixing member 31 is connected to the fixed shaft 2 through a rotating member 32. The fixed shaft 2 is a cylindrical structure. One end of the rotating member 32 is connected to the fixing member 31, and the other end is inserted into the interior of the fixed shaft 2. Preferably, in order to make the rotation smoother, a bearing 33 is provided between the rotating member 32 and the inner wall of the fixed shaft 2. In this embodiment, a slip ring 105 is also provided in the channel of the fixed shaft 2, which serves to transmit energy and signals. The setting of the slip ring 105 is a prior art and will not be elaborated here.

[0045] In some embodiments, in order to facilitate the connection of an external support device, an installation component 6 is provided on one side of the base 1 away from the antenna assembly 4, and the installation component 6 is slidably connected to the base 1. The external support device can be installed on the base 1 through the installation component 6.

[0046] Specifically, a first slider 61 is provided on the base 1. The installation component 6 includes a second slider 62 and a connection seat 63. One of the first slider 61 and the second slider 62 is provided with a sliding portion 611, and the other is provided with a sliding groove 621. The sliding portion 611 is slidably disposed in the sliding groove 621, and the connection seat 63 is connected to the second slider 62. By the relative sliding of the first slider 61 and the second slider 62, the drone countermeasure device can be quickly fixed in application scenarios such as tripods and mobile vehicle-mounted platforms, meeting the compatibility requirements of multiple devices. In this embodiment, the sliding portion 611 is provided on the first slider 61, and the sliding groove 621 is provided on the second slider 62.

[0047] Specifically, in this embodiment, in order to enable the drone countermeasure device to perform normal countermeasure work, the drone countermeasure device further includes a combiner 101, a receiver 102, a control board 103, and a power supply 104. The combiner 101 is disposed on the fixing member 31 and is used to combine multi-system signals collected by a plurality of antenna bodies arranged in an array into a set of internal signal processing systems. The receiver 102 is disposed on the fixing seat and is used to process multi-band radio signals and demodulate them into drone countermeasure signals. In this embodiment, the receiver 102 simultaneously includes modules for 8 channels, further improving the countermeasure effect of the drone countermeasure device. The control board 103 is disposed on the fixing seat and is used to control the working states of various components. The power supply 104 is disposed on the fixing seat and is used to provide different supply voltages for each component of the drone countermeasure device. The combiner 101, the receiver 102, the control board 103, and the power supply 104 are all prior arts and will not be elaborated here.

[0048] The drone countermeasure device further includes a housing 8, and the housing 8 covers the base 1. The housing 8 covers all the components disposed on the base 1 inside the housing 8, playing a protective role for the components on the base 1. At the same time, the appearance of the drone countermeasure device is made more tidy.

[0049] Specifically, the material of the housing 8 is fiberglass material. It can not only meet the protection requirements but also reduce signal shielding and interference, thereby ensuring the normal countermeasure work of the drone countermeasure device.

[0050] Preferably, a cooling device 7 is provided on one side of the base 1 close to the antenna assembly 4. The cooling device 7 is used to cool the environment between the housing 8 and the base 1, so as to improve the environmental quality inside the UAV countermeasure device, improve work efficiency and equipment reliability. In this embodiment, the cooling device 7 is a fan. In order to achieve a better cooling effect, two cooling devices 7 are provided on the base 1, and the two cooling devices 7 are respectively located on opposite sides of the fixed shaft 2. In other embodiments, different numbers of cooling devices 7 can be set according to actual cooling requirements.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
