Description

Technical Field

[0001] This utility model relates to the field of early warning and countermeasure technology, specifically to an early warning and countermeasure device for preventing detection by unmanned aerial vehicles. Background Technology

[0002] Unmanned aerial vehicle (UAV) early warning and countermeasure devices are security protection systems used to detect, identify, track, interfere with, or drive away illegal or unauthorized UAVs (commonly known as "black flight" UAVs). They are widely used in military facilities, government agencies, airports, prisons, large event venues, nuclear power plants, and other locations with high low-altitude airspace security requirements.

[0003] The patent with publication number CN221801255U discloses a panoramic UAV countermeasure system, including an optoelectronic radio-laser orientation component. A turntable body is mounted on top of the optoelectronic radio-laser orientation component, and optoelectronic radio-laser pitch components with vertical rotation function are mounted on both sides of the turntable body. The connecting component consists of a flange and an imaging platform base. This device, by setting three bearings, allows the visible light component, thermal imaging component, radio jamming and deception component, and laser strike component to be simultaneously installed on the panoramic UAV countermeasure system equipment. By stitching together real-time monitoring images from the panoramic imaging platform and multiple visible light or thermal imaging cameras, a panoramic real-time image is formed, automatically identifying and tracking UAV targets. This ensures the integration of target monitoring, detection, capture, locking, tracking, identification, early warning, jamming and deception, and laser strike systems.

[0004] However, the aforementioned countermeasures system still has the following problems in actual use: Drone countermeasure systems have a wide range of applications, not only in air transport areas such as civil aviation airports, but also in lawns or open areas of large outdoor event venues (such as music festivals and sports events).

[0005] In the aforementioned scenarios, to achieve the best countermeasure effect, it is often necessary to flexibly adjust the deployment position of the equipment according to the on-site environment, thus posing a practical requirement for the mobility of the system. However, existing drone countermeasure systems are usually bulky in structure and lack mobility themselves. During the transportation and deployment process, they rely on manual lifting or additional auxiliary equipment, which is inconvenient to operate and affects deployment efficiency and emergency response capabilities. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an early warning and countermeasure device for preventing drone detection, which can more conveniently transfer the early warning and countermeasure subject.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a warning and countermeasure device for preventing detection by unmanned aerial vehicles (UAVs), comprising a warning and countermeasure main body, a connecting plate fixedly connected to the lower end of the warning and countermeasure main body, a bottom box fixedly connected to the bottom surface of the connecting plate, a storage box fixedly connected to the inner wall of the bottom box, a cavity formed between the outer wall of the storage box and the inner wall of the bottom box, a power mechanism connected to the surface of the connecting plate, the output end of the power mechanism penetrating into the cavity and connected to four lifting components, a support component connected to the lower end of each of the four lifting components, and a moving component connected inside each of the four support components.

[0008] Furthermore, the power mechanism includes a motor, four lead screws (number 2), four synchronous belts, and eight synchronous pulleys. The outer wall of the motor is fixedly connected to the upper surface of the connecting plate. The output end of the motor is fixedly connected to the upper end of one of the lead screws (number 2). The four lead screws (number 2) are located at the four corners of the cavity. The upper ends of the four lead screws (number 2) are rotatably connected to the connecting plate. The eight synchronous pulleys are divided into four groups in pairs. The four groups of synchronous pulleys are respectively sleeved and fixedly connected to the outer wall of the upper end of the four lead screws (number 2). The four synchronous belts are respectively connected to the synchronous pulleys on two adjacent lead screws (number 2). The lower ends of the four lead screws (number 2) are respectively connected to four lifting components.

[0009] Furthermore, the lifting assembly includes a first lead screw, a slide rod, a connecting strip, and two connecting blocks. The upper end of the slide rod is fixedly connected to the bottom surface of the connecting plate. The slide rod is parallel to the second lead screw. One end of the connecting strip is sleeved and threadedly connected to the outer wall of the second lead screw. The other end of the connecting strip is sleeved and slidably connected to the outer wall of the slide rod. The upper end of the first lead screw is fixedly connected to the second lead screw through one end of the connecting strip. The lower end of the first lead screw passes through the first connecting block and is connected to the first connecting block. The second connecting block is sleeved and slidably connected to the outer wall of the slide rod. The bottom surface of the middle part of the connecting strip and the adjacent ends of the two connecting blocks are all connected to the support assembly.

[0010] Furthermore, the support assembly includes an outer column, a support block, and an inner pin. The two sides of the upper end of the outer column are fixedly connected to the adjacent ends of the two connecting blocks, respectively. A through hole is opened through the upper surface of the outer column. The upper end of the inner pin is fixedly connected to the bottom surface of the middle part of the connecting strip. The lower end of the inner pin passes through the through hole. One end of the support block is fixedly connected to one side of the inner wall of the bottom box. The lower end of the first lead screw is rotatably connected to the inner wall of the support block. The first lead screw is threadedly connected to the connected connecting block.

[0011] Furthermore, the side walls of the four outer columns are all provided with sliding openings. The sliding openings of the two outer columns on the same side inside the bottom box are slidably connected to support plates. The two ends of the two support plates are respectively fixedly connected to the two sides of the inner wall of the bottom box. The upper surfaces of the two support plates are all provided with insertion holes. The end of the inner pin away from the connecting strip passes through the insertion hole. The bottom surfaces of the two support plates are connected to the moving component.

[0012] Furthermore, the moving assembly includes four casters, the upper ends of which are rotatably connected to the two ends of the two support plates respectively, and the lowest surfaces of the four casters are lower than the lowest surface of the base box.

[0013] Furthermore, the thread progression of the No. 2 lead screw is no less than twice that of the No. 1 lead screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This early warning and countermeasure device for preventing drone detection has integrated casters at the bottom, allowing for direct pushing during daily relocation without the need for manual lifting or auxiliary equipment. Upon reaching the target location, a motor-driven screw structure lowers the outer column to lift the device, automatically lifting the casters off the ground. This enables a one-click switch from "moving state" to "stable standing state," making operation simple and efficient and solving the problems of inconvenient handling and time-consuming deployment of existing devices. This early warning and countermeasure device for preventing drone detection utilizes the speed difference between the No. 2 lead screw (with a thread progression ≥ twice that of the No. 1 lead screw) and the No. 1 lead screw. On hard surfaces (cement, asphalt), the outer column descends to provide stable support for the device. On soft surfaces (lawn, soil), the inner needle descends at a faster speed, allowing it to penetrate the outer column and insert into the soil, significantly increasing friction and preventing the device from slipping. This design enables the device to adapt to different ground conditions and broadens its application range. This early warning and countermeasure device for preventing drone detection uses a power mechanism that drives four No. 2 lead screws to rotate synchronously via a synchronous belt and synchronous pulley, so that the lifting components at the four corners move in unison. The device does not tilt to one side during the lifting process, ensuring the safety and stability of the deployment process. This early warning and countermeasure device for preventing drone detection has its mobile and support components housed within the cavity of the base box, without increasing the overall size of the device. This facilitates its transfer and deployment in narrow areas (such as crowded venues for large events) while maintaining a clean appearance. Attached Figure Description

[0017] It should be noted here that: the main body of the early warning and countermeasure is a mature technology in the early warning and countermeasure device to prevent drone detection, and its internal and external components typically include, but are not limited to: Radar systems that transmit electromagnetic waves and receive reflected signals are the core detection means for dealing with "low, slow and small" targets, enabling long-range detection, three-dimensional positioning and speed measurement of UAVs. High-definition cameras, infrared thermal imagers and other equipment enable visual recognition, classification and close-range tracking of drones, and make up for the blind spots of radar in complex environments (such as cities and forests) through photoelectric / infrared sensing systems. A radio spectrum monitoring system that enables passive detection of drones (without transmitting signals, highly stealthy) by monitoring their communication links (such as 2.4GHz / 5.8GHz control signals and GPS navigation signals), and can identify drone models, serial numbers, and other information. An acoustic monitoring system that uses a microphone array called a "sound detector" to identify the rotor or engine sounds of drones, suitable for detecting micro drones at close range (e.g., within 10 kilometers). As the core of the command and control module, it is a central controller that receives target information (such as position, speed, and type) from the detection and identification module, performs data fusion (integrating information from multiple sources such as radar, photoelectric, and radio), and achieves precise control of the countermeasure execution module. Communication jamming devices that transmit signals at the same frequency to block the communication link between the drone and its operator (such as 2.4GHz / 5.8GHz control signals), causing the drone to lose control, make an emergency landing, or return to its origin; Furthermore, in this utility model, only the mentioned structures are partially improved, while the unmentioned structures, such as radar systems and communication jamming equipment, are not modified in any way and retain their original functions and effects.

[0021] More specifically, by setting up a lifting component, the power output from the power mechanism can be smoothly applied to the support component.

[0022] As a preferred embodiment of this utility model, the support assembly includes an outer column 7, a support block 8, and an inner pin 10. The two sides of the upper end of the outer column 7 are fixedly connected to the adjacent ends of two connecting blocks 14, respectively. A through hole 701 is provided through the upper surface of the outer column 7. The upper end of the inner pin 10 is fixedly connected to the bottom surface of the middle part of the connecting strip 13, and the lower end of the inner pin 10 passes through the through hole 701. One end of the support block 8 is fixedly connected to one side of the inner wall of the bottom box 3. The lower end of the first lead screw 9 is rotatably connected to the inner wall of the support block 8, and the first lead screw 9 is threadedly connected to the connected connecting block 14.

[0023] More specifically, by setting up support components, in conjunction with the power mechanism and lifting components, the device can switch between two modes: movable and stable standing.

[0024] As a preferred embodiment of this utility model, the side walls of the four outer columns 7 are all provided with sliding openings 702. The sliding openings 702 of the two outer columns 7 on the same side inside the bottom box 3 are slidably connected to the support plate 5. The two ends of the two support plates 5 are respectively fixedly connected to the two sides of the inner wall of the bottom box 3. The upper surfaces of the two ends of the two support plates 5 are all provided with insertion holes 501. The end of the inner needle 10 away from the connecting strip 13 passes through the insertion hole 501. The bottom surfaces of the two support plates 5 are connected to the moving component.

[0025] More specifically, by setting up support plate 5, stable support can be provided for the moving component without affecting the lifting and lowering of the support component.

[0026] As a preferred embodiment of this utility model, the movable component includes four omnidirectional wheels 6, the upper ends of the four omnidirectional wheels 6 are rotatably connected to the two ends of the two support plates 5 respectively, and the lowest surface of the four omnidirectional wheels 6 is lower than the lowest surface of the base box 3.

[0027] More specifically, by setting up movable components, the entire device can be moved smoothly and conveniently when it needs to be moved.

[0028] As a preferred embodiment of this utility model, the thread progression of the No. 2 lead screw 17 is not less than twice the thread progression of the No. 1 lead screw 9.

[0029] More specifically, the purpose of this setup is to control the inner needle 10 and the outer column 7 to descend at different speeds when the power mechanism is started.

[0030] like Figures 1 to 7 As shown, the early warning and countermeasure device for preventing drone detection in this utility model can be used according to the following steps: First, place the warning and countermeasure main body 1 in any position where it can be moved (such as steps or trays, which are definitely not suitable). At this time, the four casters 6 are on the ground, and the operator can push the entire device to move on the ground using the four casters 6. Stop moving when the device moves to the designated area. The operator then turns on motor 4. The output shaft of motor 4 drives the No. 2 lead screw 17 connected to it to rotate. The rotation interface of the No. 2 lead screw 17 drives the other No. 2 lead screws 17 to rotate together through the synchronous wheel 16 on the surface. Then, the rotation of the four No. 2 lead screws 17 can push the connecting bar 13 downward through the thread (the connecting bar 13 will only move vertically and will not tilt or shift because of the cooperation of the sliding rod 12). Then, the connecting bar 13 descends and pushes the inner needle 10 to move along the through hole 701 of the outer column 7. At the same time, because the second lead screw 17 is also fixedly connected to the first lead screw 9, the first lead screw 9 will also rotate synchronously. Then, the first lead screw 9 rotates in conjunction with the connecting block 14, which can bring the outer column 7 down as well. Because the surface of the outer column 7 has a sliding opening 702, it will not obstruct the support plate 5 and the universal wheel 6 with a fixed height. Furthermore, since the thread progression of the second lead screw 17 is no less than twice that of the first lead screw 9, when the outer column 7, which is in contact with the first lead screw 9, descends a certain distance (e.g., 8cm), the inner pin 10, which is in contact with the second lead screw 17, will descend a longer distance (e.g., 16cm). Therefore, although the inner pin 10 was originally located above the outer column 7, when the outer column 7 descends to the height of passing through the universal wheel 6, the outer column 7 can lift the entire device, causing the universal wheel 6 to detach from the ground, and the device will not be displaced at this time. If the device is located on a lawn or soil surface, to enhance its anti-slip effect, motor 4 should be kept running, causing lead screw 9 and lead screw 17 to continue rotating for a while until lead screw 17 controls the inner needle 10 to descend to its lowest point (e.g., ...). Figure 5 As shown in the figure, at this time the tip of the inner needle 10 will pass through the outer column 7 and insert into the soil, thereby increasing the overall friction.

[0031] This utility model has been described with reference to the above-described embodiments and accompanying drawings. However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. On the contrary, modifications and equivalent provisions included in the spirit and scope of the claims are all included within the scope of this utility model.
