Description

Technical Field

[0001] This utility model relates to an electronic countermeasures device, and more particularly to a drone detection device with an easily detachable antenna. Background Technology

[0002] Drone detection equipment is widely used in border surveillance, airport security, protection of large public events, and defense of critical infrastructure. In these scenarios, the equipment is deployed on fixed or mobile platforms (such as towers, buildings, or vehicle-mounted systems) to detect drone radio frequency signals, GPS coordinates, or electromagnetic characteristics in real time, enabling threat identification and location. The process involves the operator configuring parameters, the equipment automatically scanning the environment, capturing signal data, analyzing it through a signal processing module, outputting alarm information, and transmitting it to the control center via the network. Routine maintenance involves periodically checking antenna performance and replacing components to ensure detection accuracy and continuity. However, their deployment locations are often exposed to harsh weather or high-frequency usage environments, increasing the maintenance frequency.

[0003] In existing technologies, antennas, as key components of UAV detection equipment, are consumables due to their exposure to harsh conditions such as wind, rain, high temperatures, and vibration. Frequent wear and tear or damage leads to a significant increase in replacement needs. However, traditional antenna assembly and disassembly mechanisms rely on screw fixing and complex wiring connections, making the process cumbersome, time-consuming, and requiring specialized tools and skills. This not only prolongs equipment downtime and affects continuous monitoring tasks but also increases maintenance costs and operational risks. Therefore, there is an urgent need to develop a rapid assembly and disassembly device to simplify the replacement process, reduce manual intervention, and improve the reliability and availability of the equipment to adapt to high-frequency maintenance scenarios. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a drone detection device with an easily detachable antenna.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A UAV detection device with easily detachable antennas, comprising a housing and several antennas mounted on the housing, wherein the antennas and the housing form a detachable connection, and a guide is provided on the antenna, the guide comprising two symmetrically arranged expansion columns, and the outer surfaces of the two expansion columns cooperate to form two virtual circles at the bottom of the antenna and at their own ends, the outer diameter of the virtual circle at the end of the guide is larger than that of the virtual circle at the bottom of the antenna, and a positioning hole is provided on the housing corresponding to the guide, the positioning hole making the outer diameters of the virtual circle at the end of the guide and the virtual circle at the bottom of the antenna tend to be the same.

[0006] The beneficial effects of this utility model are as follows: This technical solution, through the cooperation of the guide and positioning hole, achieves rapid positioning and stable connection between the antenna and the housing, avoiding misalignment during installation and improving disassembly and assembly efficiency. Specifically, the symmetrical design of the expansion joint generates elastic deformation when inserted into the positioning hole, making the outer diameter of the virtual circle more consistent, ensuring the initial fixation of the antenna in the radial and axial directions, and reducing physical damage to the housing or antenna. At the same time, the elastic characteristics of the expansion joint facilitate easy removal during disassembly, reducing maintenance costs. As a preferred method, the expansion joint can be made of elastic materials such as polyurethane or silicone rubber into a conical structure, with its end diameter slightly larger than the inner diameter of the positioning hole; during insertion, the conical end is squeezed inward by the positioning hole wall, generating radial expansion force to achieve self-locking positioning; during disassembly, the antenna can be gently pulled in the opposite direction to restore its original shape using the material's elasticity, without the need for additional tools. In addition, this structure expands the applicability of the equipment in harsh environments, such as during field operations, resisting loosening caused by wind vibration or shock, ensuring the stability of the detection signal.

[0007] Furthermore, a first mounting groove is provided on the end face of the antenna corresponding to the housing, and a plurality of snap-fit ​​blocks are provided in the first mounting groove. A second mounting groove is provided on the housing corresponding to the first mounting groove, and snap-fit ​​slots are provided in the second mounting groove corresponding to the plurality of snap-fit ​​blocks. The plurality of snap-fit ​​blocks cooperate with the corresponding snap-fit ​​slots to limit the offset of the antenna in at least two directions.

[0008] This technical solution effectively limits the antenna's horizontal offset (such as along the x and y axes) through the interlocking design of the locking block and locking slot, preventing shaking caused by external forces or vibrations after installation and improving overall stability. This not only ensures the accuracy of the antenna's detection signal but also extends the equipment's lifespan and reduces wear caused by loosening. As a preferred design, the locking block can be designed as a trapezoidal protrusion, and the locking slot as a corresponding trapezoidal groove. During installation, the guiding action of the trapezoidal slope guides the locking block into the locking slot, generating lateral constraint force to restrict the antenna's movement in multiple degrees of freedom. During disassembly, the antenna can be easily separated by simply lifting it vertically. Furthermore, this structure optimizes assembly accuracy; for example, in mass production, standardized slots enable rapid alignment, reducing human error.

[0009] Furthermore, the assembly slot is rectangular, and there are four snap-fit ​​blocks, which are respectively located at the center of the end face of the assembly slot along the width direction and along the length direction, and the snap-fit ​​blocks are arranged symmetrically in pairs.

[0010] This technical solution enhances the antenna's constraint balance in multiple directions through a rectangular assembly slot and four symmetrically distributed snap-fit ​​blocks, avoiding tilting issues caused by uneven force at a single point and improving installation uniformity and reliability. The rectangular slot design facilitates manufacturing and assembly, ensuring that the snap-fit ​​blocks form stable support points at their width and length centers, reducing vibration transmission. As a preferred approach, the corners of the rectangular slot can be chamfered, and the snap-fit ​​blocks adopt hemispherical heads. During installation, the hemispherical heads contact the curved surface of the slot wall to disperse pressure and prevent stress concentration. Simultaneously, the symmetrical layout ensures that the constraint force is evenly distributed along the x and y axes, achieving multi-directional anti-offset. Furthermore, this structure expands compatibility; for example, antennas of different sizes can be adapted using the same rectangular slot, simplifying modular equipment design.

[0011] Furthermore, the antenna has a recessed mounting part in the middle, and a rotatable rotating sleeve is fitted inside the mounting part. A connecting copper post is provided inside the antenna. When the rotating sleeve rotates, it drives the connecting copper post to move up and down. A connecting copper seat is provided in the second assembly slot corresponding to the connecting copper post.

[0012] This technical solution, through the linkage of the rotating sleeve and the connecting copper post, achieves secondary fixation and electrical connection of the antenna after positioning, improving the functional integration of the equipment. Specifically, the rotation of the rotating sleeve drives the connecting copper post to move up and down, bringing it into contact with the connecting copper base. This not only provides mechanical locking force to prevent the antenna from falling off, but also supplies power to the antenna through the conductivity of copper, simplifying the wiring of the detection system. As a preferred approach, the connecting copper post can be designed as a post with external threads, and the connecting copper base has matching internal threads. When the rotating sleeve rotates, the thread engagement drives the copper post to move axially until the threads are fully engaged and locked, while simultaneously establishing a circuit path. For disassembly, simply rotate the rotating sleeve in the opposite direction to separate the parts, balancing safety and convenience. In addition, this structure reduces the need for external connectors and lowers the risk of electromagnetic interference.

[0013] Furthermore, a spiral groove is provided on the outer diameter surface of the mounting part, and a slider is provided on the rotating sleeve, with the other end of the slider fixed to the connecting copper column. The slider is slidably disposed in the spiral groove.

[0014] In the above scheme, the axial distance of the mounting part is greater than the axial width of the rotating sleeve. Therefore, the rotating sleeve can move up and down within the mounting part when rotating, thereby driving the connecting copper column to move up and down. Furthermore, the corresponding parts of the connecting copper seat and the connecting copper column are threaded, so the rotating sleeve will not move after the connecting copper seat and the connecting copper column are engaged. This technical solution converts rotational motion into linear displacement through the cooperation of the spiral groove and the slider, achieving precise lifting and self-locking of the connecting copper column, ensuring the reliability and fixing strength of the power supply connection. The lead design of the spiral groove controls the movement distance, generating sufficient contact pressure when the copper column and the copper seat mesh, avoiding incomplete connection or loosening. As a preferred method, the spiral groove can use a single-threaded spiral with a constant slope, and the slider is a cylindrical pin. When the rotating sleeve rotates, the pin slides along the groove wall, pushing the copper column to move linearly. When the copper column is fully inserted into the copper seat, a stop protrusion is provided at the end of the groove to restrict further sliding of the slider, forming a mechanical lock to prevent accidental retraction. In addition, this structure optimizes the operating feel; for example, the shallow angle design of the groove reduces rotational force, improving user-friendliness. Attached Figure Description

[0019] This utility model embodiment provides a drone detection device with an easily detachable antenna, such as... Figure 1-4The device includes a housing 11 and several antennas 12 detachably mounted on the housing 11. The housing 11, as the main body of the device, is typically made of metal or engineering plastic and integrates a signal processing module and a power module (existing technology) for receiving and processing UAV signals detected by the antennas 12. The antennas 12 are detection radio frequency antennas, with a detachable connection between their bottoms and the housing 11 for easy replacement or maintenance. A guide 121 is provided on the antenna 12, comprising two symmetrically arranged expansion columns 1211. These expansion columns 1211 are made of an elastic material such as rubber or spring steel, and their outer surfaces form two virtual circles: one at the bottom of the antenna 12 and the other at the end of the guide 121, with the outer diameter of the end virtual circle being larger than that of the bottom virtual circle. A positioning hole 111 is provided on the housing 11 corresponding to the guide 121. The diameter of the positioning hole 111 is designed to make the outer diameters of the end virtual circle and the bottom virtual circle approximately the same, facilitating insertion and expansion positioning. A first mounting groove 122 is provided on the end face of the antenna 12 corresponding to the housing 11. The first mounting groove 122 has a rectangular groove structure and four locking blocks 1221 are provided inside it. The four locking blocks 1221 are symmetrically arranged in pairs at the center of the end face of the first mounting groove 122 along the width and length directions. A second mounting groove 112 is provided on the housing 11 corresponding to the first mounting groove 122. The second mounting groove 112 is also rectangular and has four locking slots 1121 corresponding to the four locking blocks 1221. The locking blocks 1221 cooperate with the locking slots 1121 to limit the offset of the antenna 12 in at least two directions.

[0020] The antenna 12 has a recessed mounting portion 123 in its center. The mounting portion 123 is a cylindrical groove with a spiral groove 1231 on its outer diameter surface. A rotatable rotating sleeve 124 is fitted inside the mounting portion 123. The rotating sleeve 124 is an annular structure made of insulating material, and its axial width is smaller than the axial distance of the mounting portion 123, allowing the rotating sleeve 124 to move up and down within the mounting portion 123. A connecting copper post 125 is provided inside the antenna 12 for transmitting power signals. A slider 1241 is provided on the rotating sleeve 124. The other end of the slider 1241 is fixed to the connecting copper post 125. The slider 1241 slides within the spiral groove 1231. When the rotating sleeve 124 is rotated, the sliding of the slider 1241 within the spiral groove 1231 causes the connecting copper post 125 to move up and down. A connecting copper seat 113 is provided in the second assembly slot 112 of the housing 11, corresponding to the connecting copper column 125. The connecting copper seat 113 is electrically connected to the power module of the housing 11 (which is the prior art). The corresponding parts of the connecting copper seat 113 and the connecting copper column 125 are provided with threads to facilitate fixing after mating.

[0021] When installing the antenna 12, first align the guide 121 of the antenna 12 with the positioning hole 111 of the housing 11 and insert it. After insertion into the positioning hole 111, the end of the expansion pin 1211 retracts and expands within the hole, achieving initial positioning. Simultaneously, the snap-fit ​​block 1221 in the first assembly groove 122 engages with the snap-fit ​​groove 1121 in the second assembly groove 112 to prevent the antenna 12 from shifting along the x-axis or y-axis. Next, rotate the rotating sleeve 124, and the slider 1241 slides within the spiral groove 1231, causing the connecting copper pin 125 to move downwards until it engages with the connecting copper base 113. At this point, the connecting copper pin 125 and the connecting copper base 113 are electrically connected to supply power to the antenna 12, while the rotating sleeve 124 is fixed and cannot move. During disassembly, rotate the rotating sleeve 124 in the opposite direction to move the connecting copper pin 125 upwards and disengage it from the connecting copper base 113. Then, pull out the antenna 12, and the expansion pin 1211 will elastically recover, making it easy to remove.

[0022] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
