Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) detection technology, specifically to a protective device for UAV monitoring antenna equipment. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly used in military reconnaissance, counter-terrorism and stability maintenance, border patrol, and other fields. Effective detection of drones has become an important issue in public safety and national defense security. Currently, the main detection methods for drones include radar detection, photoelectric detection, and radio frequency detection. Among them, radio frequency detection technology has been widely used in the field of drone detection due to its advantages such as passive operation, difficulty in detection, and ability to identify communication signals between the drone and the remote controller.

[0003] Existing drone radio frequency monitoring antenna equipment is typically mounted on fixed brackets or simple vehicle-mounted platforms, with the antenna itself usually fixed vertically. During operation, it can receive and detect signals from aerial drones. However, the existing technology has the following shortcomings: First, most existing monitoring antennas are exposed and fixed installations. The antennas lack effective protection measures during transportation, relocation, or non-operation. The antenna body is easily affected by external collisions, wind and rain erosion, and other environmental factors, which can lead to antenna damage or performance degradation, shortened service life, and high maintenance costs.

[0004] Secondly, the installation methods of existing detection equipment are relatively simple. The detection equipment is usually fixedly installed under the antenna, and its azimuth and tilt angles are difficult to adjust flexibly. When the target is in different directions or at different heights, the entire equipment needs to be moved manually or the antenna needs to be re-erected. The operation is cumbersome and inefficient, and it is difficult to quickly adapt to changing detection needs.

[0005] Third, in existing antenna assemblies, each antenna element is controlled independently, requiring individual operation during deployment and retraction. The lack of a synchronous linkage mechanism results in a long deployment and retraction process, leading to slow response speed in emergency deployment scenarios and affecting the timeliness of detection tasks.

[0006] Based on the above background, the inventors designed a protective device for drone monitoring antenna equipment to solve the above problems, and thus, this application is hereby filed. Summary of the Invention

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0022] like Figures 1 to 10 As shown, this embodiment provides a protective device for a drone monitoring antenna device, including a monitoring vehicle body 10 with a monitoring platform 101 on the roof, a mounting cylinder 102 disposed on the monitoring platform 101, multiple antenna assemblies 20 disposed on the outer peripheral wall of the mounting cylinder 102, and multiple protective assemblies 30 for housing the antenna assemblies 20. Multiple sets of protective components 30 are set on the monitoring platform 101 and distributed around the mounting cylinder 102, and the number and orientation of the protective components 30 correspond to those of the antenna components 20. It also includes a lifting assembly 40, a wiring assembly 60, a detection device 105 disposed in the mounting cylinder 102, and a mounting assembly 50 for mounting the detection device 105 and adjusting its orientation and tilt angle; The mounting component 50 is disposed on the output end of the lifting component 40 and can be freely raised and lowered inside the mounting cylinder 102 along the axial direction of the lifting component 40. The wiring assembly 60 has multiple sets distributed circumferentially along the mounting cylinder 102. The wiring assembly 60 includes a connector 607 that can move freely radially along the mounting cylinder 102 and is used to connect to the detection device 105.

[0023] This embodiment employs an antenna assembly 20, a protective assembly 30, a lifting assembly 40, a mounting assembly 50, and a wiring assembly 60, arranged sequentially from the outside to the inside. The detection device 105 is housed within the mounting assembly 50. This spatial arrangement allows the antenna body 202 of the antenna assembly 20 to achieve different technical effects in different states. Specifically, when the antenna body 202 is in a non-operating horizontal state, the protective assembly 30 provides protection. When the antenna body 202 is in an operating vertical state, detection can be performed. Furthermore, the detection device 105 can be adjusted for azimuth and tilt angle via the mounting assembly 50, thus expanding its detection range. The application scope, the setting of the lifting component 40, the mounting component 50 and the wiring component 60, and the connector 607 of the wiring component 60 can move radially back and forth, so that when the antenna body 202 is in a non-working state, the connector 607 can be disconnected from the detection device 105, and when the antenna body 202 is in a working state, the connector 607 can be connected to the interface 106 of the detection device 105. So when the antenna component 20 is in a working state, the circuit is automatically connected, and when the antenna component 20 is in a non-working state, the circuit can be automatically disconnected. Therefore, through the spatial layout and collaborative work of multiple components, this application makes it extremely convenient to switch between the working state and the storage state of the antenna component 20, which is suitable for the passive radio frequency detection scenario of UAVs.

[0024] In this embodiment, the antenna assembly 20 includes a frame 201, a rotating shaft rotatably connected within the frame 201, and an antenna body 202 with one end disposed on the rotating shaft; One end of the rotating shaft passes through the frame 201 and extends outward with a mounting section; The antenna assembly 20 further includes a first bevel gear 203 disposed on the mounting section, and a second bevel gear 204, a first gear 206 and a connecting shaft 205 coaxially fixedly connected. The first gear 206 and the second bevel gear 204 are respectively disposed at both ends of the connecting shaft 205. The connecting shaft 205 is rotatably connected to the frame 201, and the first bevel gear 203 and the second bevel gear 204 mesh. The antenna assembly 20 also includes a rotating ring 208 coaxially arranged with the mounting cylinder 102, and an antenna drive motor 209 for driving the rotating ring 208 to rotate. The rotating ring 208 is rotatably connected to the monitoring platform 101, and a first gear ring 207 that meshes with the first gear 206 is provided on the rotating ring 208. The power output end of the antenna drive motor 209 is coaxially and fixedly connected to the rotating shaft of one of the antenna components 20.

[0025] Those skilled in the art will understand that by controlling the output shaft of the antenna drive motor 209 to rotate, the rotating shaft of the antenna assembly 20 rotates, which in turn drives the first bevel gear 203 and the second bevel gear 204 of the antenna assembly 20 to rotate. The rotation of the second bevel gear 204, in turn, drives the first gear 206 to rotate through the rotating shaft, thereby causing the first gear ring 207 meshing with the first gear 206 to rotate. The rotation of the first gear ring 207 around its central axis drives the first gear 206 of multiple antenna assemblies 20 to rotate. Then, through the first bevel gear 203 and the second bevel gear 204, the antenna body 202 can be rotated. Therefore, in this embodiment, by controlling the output shaft of the antenna drive motor 209 to rotate, the antenna bodies 202 of all antenna assemblies 20 can be driven to rotate synchronously, allowing all antenna bodies 202 to switch between horizontal and vertical states. Of course, in some embodiments, the antenna bodies 202 of multiple antenna assemblies 20 can also be in an inclined state. Those skilled in the art can set it according to their needs, which will not be elaborated here.

[0026] In this embodiment, the protective component 30 includes a protective tube 304 arranged radially along the mounting cylinder 102 and a transmission mechanism for driving the protective tube 304 to reciprocate radially along the mounting cylinder 102. The transmission mechanism includes a first fixed frame 301 disposed on the monitoring platform 101, a first guide rod 303 and a first lead screw 302 disposed within the first fixed frame 301, and a movable plate 305 disposed within the first fixed frame 301; The first guide rod 303 and the first lead screw 302 are both arranged radially along the mounting cylinder 102. The movable plate 305 is spirally connected to the first lead screw 302, and the movable plate 305 is slidably connected to the first guide rod 303. The protective tube 304 is fixed on the movable plate 305.

[0027] Those skilled in the art will understand that by setting a first guide rod 303 and a first lead screw 302, with the first guide rod 303 and the first lead screw 302 arranged in parallel, and a movable plate 305 screwed to the first lead screw 302 and slidably connected to the first guide rod 303, when the first lead screw 302 is driven to rotate, the movable plate 305 can be moved along the axial direction of the first guide rod 303. A protective tube 304 is also set on the movable plate 305, and the protective tube 304 is parallel to the first guide rod 303. When the antenna body 202 is in a horizontal state, driving the first lead screw 302 to rotate allows the protective tube 304 to be fitted onto the horizontally positioned antenna body 202, thus completing the storage and protection of the antenna body 202. Simultaneously, when the antenna body 202 is stored, the connector 607 of the wiring assembly 60 can be disconnected from the interface 106 of the detection device 105, thus disconnecting the circuit.

[0028] In this embodiment, the protective component 30 further includes a second gear 306 disposed on the first lead screw 302; It also includes a first end face gear ring 31 for driving multiple sets of protective components 30 to rotate simultaneously. The first end face gear ring 31 is coaxially arranged with the mounting cylinder 102. The mounting cylinder 102 is located inside the first end face gear ring 31. The first end face gear ring 31 is rotatably connected to the monitoring platform 101. The top of the first end face gear ring 31 is provided with several teeth that mesh with the second gear 306. It also includes a first stepper motor 32 for synchronously moving the protective tubes 304 of multiple sets of protective components 30, wherein the first lead screw 302 of a set of protective components 30 extends out of the first fixed frame 301, and the drive shaft of the first stepper motor 32 is coaxially and fixedly connected to one end of the first lead screw 302 extending out of the first fixed frame 301.

[0029] In this embodiment, by setting a second gear 306, a first end face gear ring 31, and a first stepper motor 32, when the first end face gear ring 31 rotates, it can drive the second gears 306 of multiple sets of protective components 30 to rotate synchronously, thereby driving the first lead screws 302 of multiple sets of protective components 30 to rotate synchronously, so that the protective tubes 304 of multiple sets of protective components 30 can synchronously approach or move away from the antenna body 202. In this embodiment, the first lead screw 302 of one set of protective components 30 extends out of the first fixed frame 301, and the drive shaft of the first stepper motor 32 is coaxially fixedly connected to one end of the first lead screw 302 extending out of the first fixed frame 301, so that the first stepper motor 32 can drive the first lead screw 302 of one set of protective components 30 to rotate, thereby driving the first end face gear ring 31 to rotate, thereby driving the first lead screws 302 of other protective components 30 to rotate synchronously, so that the protective tubes 304 of multiple sets of protective components 30 can synchronously approach or move away from the antenna body 202.

[0030] In this embodiment, the lifting assembly 40 includes a second guide rod 402 and a second lead screw 401 arranged in parallel, and a lifting ring 405 disposed between the second lead screw 401 and the second guide rod 402; The mounting component 50 is disposed within the lifting ring 405 and is rotatably connected to it; The lifting assembly 40 also includes a first connecting rod 403 and a second connecting rod 404, as well as a second stepper motor 406 that drives the second lead screw 401 to rotate. One end of the first connecting rod 403 is fixedly connected to the lifting ring 405, and the other end is screwed to the second lead screw 401. One end of the second connecting rod 404 is fixedly connected to the lifting ring 405, and the other end is slidably connected to the second guide rod 402. The second stepper motor 406 is located at the bottom of the monitoring platform 101, and the output shaft of the second stepper motor 406 is coaxially and fixedly connected to the second lead screw 401.

[0031] Those skilled in the art will understand that by setting the second stepper motor 406 to drive the second lead screw 401 to rotate, and the second lead screw 401 and the second guide rod 402 are arranged in parallel, the lifting ring 405 can be raised and lowered vertically. In this embodiment, the first connecting rod 403 and the second connecting rod 404 are both L-shaped. In some embodiments, they can also be set to other shapes, which will not be described in detail here.

[0032] In this embodiment, a cover plate 104 is also provided on the mounting cylinder 102. Two symmetrically arranged extension rods are provided on the cover plate 104. Two sets of vertically arranged cylinders 103 are provided on the monitoring platform 101. The output ends of the two sets of cylinders 103 are respectively connected to the two extension rods, so that the cylinders 103 can push the cover plate 104 to rise or fall.

[0033] In this embodiment, the mounting assembly 50 includes a rotating ring 502 and a first drive motor 501 for driving the rotating ring 502 to rotate to adjust the tilt angle of the detection device 105. The rotating ring 502 is rotatably connected to the lifting assembly 40 in a direction parallel to the monitoring platform 101. The mounting assembly 50 also includes a mounting plate 503 for adjusting the orientation of the detection device 105, and a second drive motor 505 for driving the mounting plate 503 to rotate along its axis. The power output end of the second drive motor 505 is connected to the mounting plate 503 in a transmission connection. The mounting plate 503 is coaxially arranged with the rotating ring 502, and the mounting plate 503 is located inside the rotating ring 502 and rotatably connected to it. The detection device 105 is disposed within the mounting plate 503 and is coaxially arranged therewith; The second drive motor 505 is mounted on the rotating ring 502.

[0034] Those skilled in the art will understand that by setting up a first drive motor 501 and a second drive motor 505, when the first drive motor 501 is controlled to rotate, it can drive the rotating ring 502 to rotate, thereby adjusting the tilt angle of the rotating ring 502. The detection device 105 is located within the mounting assembly 50, allowing its tilt angle to be adjusted synchronously. The power output end of the second drive motor 505 is connected to the mounting plate 503, enabling it to drive the mounting plate 503 to rotate along its own central axis, thus adjusting the orientation of the mounting plate 503. The detection device 105 is located within the mounting plate 503, allowing the second drive motor 505 to adjust its orientation. Therefore, by controlling the first drive motor 501 and the second drive motor 505, the tilt angle and orientation of the detection device 105 can be adjusted.

[0035] In this embodiment, the mounting assembly 50 further includes a double gear ring 506 fixed on the mounting plate 503 and coaxially arranged therewith, and a third gear 507 and a fourth gear 508 rotatably connected to the mounting plate 503 and distributed on the outer and inner sides of the mounting plate 503, respectively. The third gear 507 and the fourth gear 508 mesh with the teeth on the outer and inner sidewalls of the double gear ring 506. The mounting assembly 50 also includes multiple clamping members 509 for clamping the detection device 105, and a third drive motor 510 for synchronous movement of multiple sets of clamping members 509. The clamping members 509 are arranged radially along the mounting plate 503 and slidably connected thereto. The clamping members 509 are provided with a number of teeth that mesh with the fourth gear 508. The output shaft of the third drive motor 510 is coaxially and fixedly connected to the gear shaft of the third gear 507. Multiple clamping members 509 are distributed circumferentially along the mounting plate 503, and the number of clamping members 509 is the same as the number of third gears 507.

[0036] Those skilled in the art will understand that, through the double gear ring 506, the third drive motor 510, the third gear 507, and the fourth gear 508, when the output shaft of the third drive motor 510 rotates, it can drive the third gear 507 to rotate, which in turn drives the double gear ring 506 to rotate along its own axis. The rotation of the double gear ring 506 can then drive the rotation of the fourth gear 508, which meshes with the teeth on the clamping member 509. The clamping member 509 is radially arranged along the mounting plate 503 and slidably connected to it. Therefore, by controlling the rotation of the output shaft of the third drive motor 510, multiple clamping members 509 can be controlled to synchronously approach or move away from the detection device 105 installed in the mounting plate 503, thereby clamping or releasing the detection device 105, and realizing the installation and release of the detection device 105.

[0037] In this embodiment, the mounting assembly 50 further includes a second gear ring 504 coaxially arranged with the rotating ring 502, and the second gear ring 504 is fixedly connected to the mounting plate 503; The output shaft of the second drive motor 505 is provided with a transmission gear that meshes with the second gear ring 504; Two coaxial pins are fixed on both sides of the rotating ring 502. The pins are rotatably connected to the lifting assembly 40. The first drive motor 501 is fixed on the lifting assembly 40, and the output shaft of the first drive motor 501 is coaxially fixedly connected to one of the pins.

[0038] In this embodiment, by providing two coaxially arranged pins on both sides of the rotating ring 502, the first drive motor 501 can directly drive the rotating ring 502 to rotate along the central axis of the pins. The transmission gear on the second drive motor 505 meshes with the second gear ring 504, so that when the second drive motor 505 rotates, it can drive the second gear ring 504 to rotate. The second gear ring 504 is fixedly connected to the mounting plate 503. Therefore, when the second drive motor 505 rotates, it can directly drive the mounting plate 503 to rotate, so that the orientation of the detection device 105 installed in the mounting plate 503 can be adjusted.

[0039] In this embodiment, the wiring assembly 60 includes a second fixed frame 601 fixed to the bottom of the mounting cylinder 102 and a movable plate 605 disposed in the second fixed frame 601 and freely movable, as well as a third lead screw 602 and a third guide rod 603 arranged in parallel, both the third lead screw 602 and the third guide rod 603 being arranged radially along the mounting cylinder 102. The movable plate 605 is slidably connected to the third guide rod 603, and the movable plate 605 is helically connected to the third lead screw 602; The wiring assembly 60 also includes a sleeve 606 disposed on the movable plate 605 and having a cable inside, and a connector 607 disposed at the end of the sleeve 606. The bottom of the detection device 105 is provided with multiple interfaces 106 that are distributed along the axis and adapted to the connectors 607 of multiple sets of wiring assemblies 60.

[0040] Those skilled in the art will understand that, through the configuration of the third lead screw 602 and the third guide rod 603, as well as the moving plate 605 and the second fixed frame 601, the third lead screw 602, when rotating, can drive the moving plate 605 to move radially along the axial direction of the third guide rod 603 in the mounting cylinder 102. The top of the moving plate 605 is connected to a sleeve 606, and a connector 607 is provided at the end of the sleeve 606. This allows the connector 607 to move radially in the mounting cylinder 102 as the moving plate 605 moves, thereby enabling the connector 607 to move inward to connect with the interface 106 of the detection device 105 to achieve circuit connection, or to move outward away from the interface 106 of the detection device 105 to achieve circuit disconnection.

[0041] In this embodiment, the wiring assembly 60 further includes a fifth gear 604 disposed at the end of the third lead screw 602; It also includes a second end face gear ring 62 coaxially arranged and rotatably connected to the mounting cylinder 102, and a third stepper motor 61 for driving the second end face gear ring 62 to rotate along its axis. The top of the second end face gear ring 62 is provided with a plurality of teeth that mesh with the fifth gear 604. The output shaft of the third stepper motor 61 is coaxially and fixedly connected to the third lead screw 602 of one of the wiring assemblies 60.

[0042] Those skilled in the art will understand that by setting the fifth gear 604, the second end face gear ring 62, and the third stepper motor 61, the third stepper motor 61 can drive the second end face gear ring 62 to rotate along its own axis, thereby driving the connectors 607 of multiple sets of wiring components 60 to move synchronously, so that the connectors 607 of multiple sets of wiring components 60 can be synchronously connected to the interface 106 of the detection device 105 or synchronously disconnected from the interface 106 of the detection device 105.

[0043] The working principle of this embodiment is as follows: S1. By controlling the extension of the output shaft of the cylinder 103, the cover plate 104 moves upward. The operator places the detection device 105 into the interior of the mounting plate 503. By controlling the rotation of the third drive motor 510, all the clamping parts 509 move synchronously toward the center of the mounting plate 503, thereby clamping and installing the detection device 105. S2. By controlling the second stepper motor 406 to rotate, the second lead screw 401 rotates, which in turn causes the lifting ring 405 to move downward as a whole, driving the detection device 105 to move downward, so that the height of the interface 106 on the detection device 105 matches the height of the connector 607 of the wiring assembly 60. At the same time, by controlling the first stepper motor 32 to rotate, the first lead screw 302 rotates, thereby driving all the protective tubes 304 away from the antenna body 202, realizing the separation of the antenna body 202 from the protective tubes 304, and releasing the antenna body 202 from its stored state. S3. By controlling the rotation of the third stepper motor 61, the third lead screw 602 of one set of wiring components 60 is rotated, which in turn drives the second end face gear ring 62 to rotate, so that the connectors 607 of multiple sets of wiring components 60 synchronously approach the interface 106 on the detection device 105, so that the interface 106 on the detection device 105 is connected to the connector 607 of the wiring component 60, thereby connecting all antenna bodies 202 to the detection device 105. S4. By controlling the antenna drive motor 209 to rotate, the rotating shaft of the antenna assembly 20 rotates synchronously, so that all the antenna bodies 202 change from a horizontal state to a vertical state, thus completing the preparation for the UAV detection work. S5. When detecting a drone, the drone continuously radiates radio signals as it flies in the air. These signals propagate in all directions in the form of electromagnetic waves. Multiple sets of antenna bodies 202 distributed around the device simultaneously capture these electromagnetic waves and convert them into electrical signals. These electrical signals are transmitted to the detection device 105. After receiving multiple signals, the detection device 105 immediately begins spectrum scanning and feature comparison to determine whether these signals belong to known drone signals. If it is confirmed to be a drone signal, it outputs the detection results such as the type, location, and frequency of the drone, thereby realizing passive radio frequency detection of the drone. Furthermore, during detection, the second drive motor 505 can be controlled to rotate, causing the mounting plate 503 to rotate, thereby adjusting the orientation of the detection device 105. In addition, by controlling the first drive motor 501 to rotate, the rotating ring 502 and the mounting plate 503 can be tilted as a whole, thereby adjusting the tilt angle of the detection device 105 and improving the applicability of the detection. S6. When the drone is not needed to monitor the antenna equipment, the antenna drive motor 209 is controlled to rotate in the opposite direction, so that all the antenna bodies 202 are switched from the vertical state to the horizontal state. Then, the connector 607 of the wiring assembly 60 is controlled to move away from the interface 106 of the detection device 105, and the protective tube 304 is controlled to be fitted onto the antenna body 202, so as to complete the storage and protection of the antenna body 202.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
