TECHNICAL FIELD
[0001] The utility model relates to countermeasure equipment technical field, especially in space unmanned aerial vehicle countermeasure equipment. BACKGROUND
[0002] With the rapid development of unmanned aerial vehicle technology, its application in military, civil and commercial fields is increasingly widespread. Space unmanned aerial vehicle becomes an important part of modern technology due to its high mobility, long endurance and ability to perform tasks in complex environments. However, the popularity of unmanned aerial vehicle technology also brings security risks, such as illegal intrusion, privacy leakage and other problems. To cope with such threats, the research on countermeasures for unmanned aerial vehicles has gradually emerged. At present, the main technical means for countermeasures for unmanned aerial vehicles include signal interference, laser weapons, net catching devices and electronic deception, etc. Among them, signal interference technology is widely concerned due to its low cost, simple operation and small environmental impact. Traditional signal interference equipment usually adopts fixed or portable design, which interferes with the communication link or navigation system of unmanned aerial vehicle by emitting electromagnetic waves, forcing it to land or return.
[0003] Although the existing technology has made certain progress in the field of signal interference, there are still many deficiencies. First of all, the directivity of traditional interference equipment is poor, and the signal coverage range is limited, which makes it difficult to accurately locate the target unmanned aerial vehicle, resulting in low interference efficiency. Secondly, the existing equipment is mostly fixed installation or manual angle adjustment, lacking flexible mechanical structure support, and unable to quickly adapt to the changes of dynamic targets. In addition, due to unreasonable structure design, the anti-vibration performance of part of the equipment is poor, which is difficult to stably run in complex environment, especially in the high-speed motion scene of space unmanned aerial vehicle, the equipment is easy to be affected by vibration and lead to failure. CONTENT OF THE UTILITY MODEL
[0004] In view of the deficiencies in the prior art, the utility model provides a space unmanned aerial vehicle countermeasure equipment, which comprises a signal jammer, a mounting rack is fixedly connected to the signal jammer, a reflecting plate is connected to the mounting rack through a rotating shaft, a first gear is fixedly connected to the rotating shaft, a second gear is rotatably connected to the mounting rack, a first motor for driving the second gear to rotate is installed on the mounting rack, a movable rack is connected to the mounting rack, a second motor is fixedly connected to the movable rack, the output shaft of the second motor is fixedly connected with the mounting rack, a motor box is arranged on one side of the movable rack, and an oscillating motor is installed in the motor box.
[0005] A mounting plate is fixedly connected to the output shaft of the oscillating motor, and the mounting plate is connected with the movable rack through bolts.
[0006] A connecting arm is welded on the upper part of the motor box, and a connecting head is welded on the upper part of the connecting arm.
[0007] The upper part of the signal jammer is provided with an antenna, and the front side of the signal jammer is provided with a display screen.
[0008] The connecting head is provided with a side plate connected through bolts, an adapter block is welded on the side plate, and a UAV connecting plate is welded on the upper part of the adapter block.

[0010] Compared with the prior art, the beneficial effects of the utility model lie in that the reflecting plate provided on the mounting frame is used in cooperation with the first gear and the second gear to realize accurate adjustment of the angle of the reflecting plate. This design enables the signal jammer to dynamically adjust the reflecting angle according to the position of the target UAV, thereby realizing more accurate signal jamming and greatly improving the interference efficiency. At the same time, due to the simple and efficient reflecting plate adjusting mechanism, the response speed is fast, and the angle adjustment can be completed in a short time, which adapts to the high-speed moving target.
[0011] Secondly, the device performs well in flexibility and adaptability. The second motor on the movable frame drives the whole device to rotate, and the mounting plate is swung by the swing motor, so that the device can not only cover all directions in the horizontal direction, but also can be flexibly adjusted in the vertical direction, ensuring that effective interference measures can be taken on UAVs from different directions. In addition, the damping ball and the limiting plate and other components in the buffer connecting piece effectively improve the anti-vibration performance of the device, ensuring its stable operation in complex environments, especially in severe conditions such as high-altitude strong wind, which can still maintain good working state.
