Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of antenna brackets, specifically a ground antenna bracket suitable for fixed platforms. Background Technology
[0002] In the field of wireless communication, ground-based fixed platforms, such as base stations in remote areas, emergency communication points, and field monitoring stations, often need to be equipped with antennas to receive and transmit signals. These application scenarios place high demands on the stability, adjustability, and anti-interference capabilities of antenna supports. Currently, many fixed antenna supports have significant shortcomings: First, height and angle adjustments largely rely on manual operation, which is cumbersome and inaccurate, making it difficult to quickly and accurately align with the signal source; second, traditional supports lack effective locking mechanisms, making them prone to displacement under the influence of external forces such as strong winds, leading to signal interruption; third, antenna transmission cables are often exposed, making them susceptible to environmental influences and difficult to manage, and electromagnetic interference generated by drive components such as motors can easily affect signal transmission quality. Utility Model Content
[0003] The purpose of this invention is to provide a ground antenna bracket suitable for fixed platforms, which combines the advantages of stability, convenience, intelligence, and anti-interference, thereby improving the communication quality and reliability of fixed platforms.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a ground antenna support suitable for a fixed platform, characterized in that it comprises:
[0005] A substrate for fixing to the ground, wherein at least one T-slot is formed on its top surface;
[0006] The first rod is detachably mounted on the substrate via a splicing mechanism;
[0007] A lifting device is installed inside the first rod body and is used to drive the second rod body to extend and retract relative to the first rod body;
[0008] A rotating mechanism is fixedly mounted on the top of the second rod and is used to drive the antenna mounting assembly to rotate horizontally.
[0009] The antenna mounting assembly is connected to the output end of the rotating mechanism and is used to mount at least one antenna.
[0010] Through modular design (substrate, first rod, lifting device, rotating mechanism, antenna mounting components), a complete and comprehensive antenna support solution is provided. The T-slot design makes installation and disassembly flexible and convenient, and is suitable for a variety of fixed platforms. The integration of lifting and rotating functions allows the antenna to be freely adjusted in position and angle in three-dimensional space, which greatly optimizes the signal reception quality.
[0011] In a further technical solution, the splicing mechanism includes a splicing plate fixed to the bottom end of the first rod body, the splicing plate being connected to the T-slot on the base plate by splicing bolts; and a plurality of reinforcing ribs being fixed between the splicing plate and the first rod body.
[0012] The combination of the splicing plate and the T-slot provides a strong and adjustable connection force, ensuring the stability of the connection between the support body and the base plate. The setting of the reinforcing rib significantly enhances the structural strength and bending and torsional resistance at the connection between the first rod and the splicing plate, effectively preventing deformation or breakage of the connection part under strong winds or long-term use, and improving the overall reliability.
[0013] A further technical solution is that the lifting device includes: a rotating screw, which is rotatably disposed in the first rod body, and its extension direction is the same as the axial direction of the first rod body;
[0014] A lifting motor is fixed on the first rod body, and its output shaft is connected to the rotating screw through a gear transmission pair;
[0015] The second rod is slidably disposed within the first rod, and its cross-section is non-circular; the rotating screw extends into the second rod and is threadedly engaged with the second rod.
[0016] The screw lifting system driven by a motor has high transmission efficiency and good self-locking properties, and can reliably stop after being raised to a designated height without falling due to the antenna's own weight or external forces. The sliding fit of the non-circular rod effectively prevents the second rod from rotating during the lifting process, ensuring the smoothness and accuracy of the lifting process.
[0017] In a further technical solution, the gear transmission pair includes a power gear fixed on the output shaft of the lifting motor and a driven gear fixed on the rotating screw, wherein the power gear and the driven gear mesh with each other.
[0018] Gear transmission pairs (drive gear and driven gear) have a compact structure and can efficiently and reliably transmit the power of the motor to the rotating screw.
[0019] In a further technical solution, the rotating mechanism includes a rotating motor fixed to the top of the second rod, the output axis of the rotating motor is axially upward and fixedly connected to a rotating shaft, and the antenna mounting assembly is mounted on the top of the rotating shaft.
[0020] The rotating motor enables the antenna mounting assembly to rotate 0 degrees horizontally without any dead angles, allowing for quick and precise alignment with the signal source.
[0021] A further technical solution also includes a limiting mechanism, which includes a fixing plate fixed to the rotary motor;
[0022] A limit motor is fixed to the fixed plate;
[0023] The sliding block is slidably engaged with the guide block disposed on the fixed plate and is driven to move linearly by the limit motor;
[0024] A limiting plate is fixed to the sliding block, and its movement trajectory is set to be able to abut or disengage from the rotating shaft.
[0025] The limiting mechanism uses a motor-driven limiting plate to directly press the rotating shaft rod, which can mechanically lock it after the horizontal angle is adjusted. This greatly enhances the wind resistance and stability of the rotating mechanism, prevents the antenna from deflecting in strong winds, and ensures continuous and stable signal reception.
[0026] In a further technical solution, the antenna mounting assembly includes:
[0027] A sealed box is fixed to the top of the rotating shaft.
[0028] A rotating rod is rotatably mounted on the enclosed box, with its axis set horizontally;
[0029] A pitch drive device, located inside the enclosed box, is used to drive the rotating rod to rotate.
[0030] The rotating rod has antenna mounting parts at both ends for mounting the antenna rod.
[0031] The enclosed enclosure not only protects the internal pitch drive mechanism from environmental factors such as rain and dust, extending its service life, but more importantly, its metal casing effectively shields against electromagnetic interference generated by the rotating motor, ensuring the purity of the antenna signal. The rotating rod structure allows for pitch angle adjustment of the antenna, further optimizing the reception angle.
[0032] In a further technical solution, the pitch drive device includes a circular rack fixed to the rotating rod and a rotating gear driven by a rotating motor and meshing with the circular rack.
[0033] The rotating rod is driven by a gear and rack mechanism, which ensures high transmission precision and large torque, thus guaranteeing the accuracy and reliability of antenna elevation angle adjustment and preventing displacement under vibration or wind.
[0034] A further technical solution also includes a hub tube, which is fixed to the first rod and is L-shaped; the rotating rod has a through hole for guiding the transmission line inside the antenna rod into the hub tube.
[0035] The L-shaped conduit provides a neat and secure routing path for the antenna transmission lines, avoiding the pulling, wear, and aging problems that can result from messy exposed cables. At the same time, it physically isolates the transmission lines from potential interference sources such as rotating motors, further reducing interference during signal transmission.
[0036] In a further technical solution, the antenna mounting portions at both ends of the rotating rod are insertion holes, and the two antenna rods are detachably inserted into the insertion holes, with the polarization directions of the antennas mounted on the two antenna rods being perpendicular to each other.
[0037] The plug-in holes enable quick installation and replacement of the antenna masts, facilitating maintenance. The perpendicular polarization of the two antenna masts allows the bracket to simultaneously receive horizontally and vertically polarized signals, improving communication capacity and signal quality, making it highly practical.
[0038] In summary, this utility model has the following beneficial effects: through multiple designs such as substrate T-slot connection, reinforcing ribs, screw lifting self-locking, and independent motor drive limit mechanism, the structural stability of the bracket and the reliability of antenna pointing are guaranteed under various environmental conditions.
[0039] It integrates three-dimensional adjustment functions: height adjustment, horizontal rotation, and pitch adjustment. All functions are driven by motors and can be remotely controlled. The adjustment process is smooth and precise, saving time and effort, and can maximize the optimization of the antenna's angle to the star or signal tower.
[0040] The drive motor is shielded by a closed enclosure, and the signal transmission line is isolated from the interference source through a hub, which effectively reduces the impact of electromagnetic interference on the signal reception quality and ensures the purity and stability of the communication signal.
[0041] Its modular design facilitates transportation, installation, and maintenance; its detachable connection allows it to flexibly adapt to different fixed platforms; and its support for dual-polarized antennas enables it to meet diverse modern communication needs. Attached Figure Description

[0049] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0050] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0054] like Figures 1-5 As shown, a ground antenna support suitable for a fixed platform includes a base plate 10, which is fixed to the ground. Two T-shaped grooves 11 are formed on the top surface of the base plate 10. The T-shaped grooves 11 are T-shaped. A first rod 21 is installed on the base plate 10. A splicing plate 22 is fixed on the ground of the first rod 21. Several evenly distributed reinforcing ribs 24 are fixed on the splicing plate 22. In this embodiment, four reinforcing ribs are provided. The reinforcing ribs 24 are fixed to the first rod 21. The splicing plate 22 is fixed to the base plate 10 by splicing bolts 23.
[0055] In one embodiment, the first rod 21 is rectangular, and a second rod 31 that can extend upward is slidably disposed within the first rod 21. The second rod 31 is also rectangular. A rotating screw 25 extending vertically is rotatably disposed within the first rod 21. A driven gear 28 is fixed on the outer periphery of the rotating screw 25. A lifting motor 26 is fixed on the first rod 21. The lifting motor 26 is poweredly connected to a power gear 27 that extends into the first rod 21. The power gear 27 meshes with the driven gear 28. The rotating screw 25 extends upward and inserts into the second rod 31, and is threadedly connected to the second rod 31.
[0056] The operation of the lifting motor 26 drives the power gear 27 to rotate, which in turn drives the driven gear 28 to rotate, thereby driving the rotating screw 25 to rotate. Since the second rod 31 is rectangular and the first rod 21 is also rectangular, the second rod 31 slides into the first rod 21. Therefore, when the rotating screw 25 rotates, it will drive the second rod 31 to move up and down through the screw thread, thereby realizing the adjustment of the height of the second rod 31.
[0057] In one embodiment, a rotary motor 40 is fixed to the top of the second rod 31, and a rotating shaft 46 is poweredly connected to the top of the rotary motor 40. A closed box 51 is fixed to the top of the rotating shaft 46. A horizontally arranged rotating rod 54 is rotatably arranged on the closed box 51. The rotating rod 54 passes through the closed box 51. A circular rack 53 is fixed on the outer periphery of the rotating rod 54. A rotary motor is arranged inside the closed box 51. A rotating gear 52 is poweredly connected to one end of the rotary motor. The rotating gear 52 meshes with the circular rack 53.
[0058] In one embodiment, antenna rods 55 are detachably inserted into both ends of the rotating rod 54, and antennas 56 are fixed on the antenna rods 55. The two antennas 56 are vertically arranged. Specifically, the rotating rod 54 has insertion holes at both ends for inserting the antenna rods 55. The antenna 56 on one antenna rod 55 is horizontally arranged, and the antenna 56 on the other antenna rod 55 is vertically arranged. The antenna rod 55 is hollow and is used to install transmission lines.
[0059] In one embodiment, a fixing plate 41 is fixed on the rotary motor 40, a limit motor 42 is fixed on the fixing plate 41, a guide block 43 is fixed on the fixing plate 41, a sliding block 44 is slidably disposed inside the guide block 43, the power output shaft of the limit motor 42 is threadedly connected to the sliding block 44, a limit plate 45 is fixed to one end of the sliding block 44, and the limit plate 45 can abut against the rotating shaft 46 to prevent the rotating shaft 46 from rotating.
[0060] In one embodiment, a hub tube 60 is fixed on the first rod 21. The hub tube 60 is L-shaped and is used to encapsulate the transmission line of the antenna rod 55. A wire hole 57 is provided on the rotating rod 54, and the line of the antenna rod 55 extends into the hub tube 60 through the wire hole 57.
[0061] A method for using a ground antenna bracket suitable for a fixed platform: First, insert the transmission lines of the two antenna rods 55 into the rotating rod 54 and extend them through the wire hole 57. Then, insert the antenna rods 55 into both ends of the rotating rod 54 and fix them. The antenna rods 55 can be tightened by opening threaded holes in the rotating rod 54 and inserting bolts to prevent the antenna rods 55 from separating from the rotating rod 54. Then, insert the transmission lines into the hub 60.
[0062] Then the first rod 21 is installed on the base plate 10. The base plate 10 and the splicing plate 22 are fixed by tightening the four splicing bolts 23. Heavy objects can be placed on the base plate 10 to prevent the antenna support from tipping over, or the base plate 10 can be installed on a box that holds heavy objects. For example, threaded holes are provided on the base plate 10, and the base plate 10 is fixed to the box by inserting screws.
[0063] Secondly, by controlling the operation of the lifting motor 26, the lifting motor 26 can rotate in both directions. The power gear 27 drives the driven gear 28 to rotate, which in turn causes the rotating screw 25 to rotate, thereby raising and lowering the second rod 31 to adjust the height. Then, the rotating motor 40 is controlled to operate, and the rotating motor 40 drives the rotating shaft 46 to rotate, thereby adjusting the horizontal position. The operation of the rotating motor 40 and the lifting motor 26 can be controlled remotely.
[0064] After adjustment, the limit motor 42 operates, driving the sliding block 44 to move, thereby causing the limit plate 45 to stick to the rotating shaft 46 for pressing, preventing the rotating shaft 46 from rotating and improving wind resistance.
[0065] Then, by controlling the rotating motor to control the rotating gear 52 to work, the circular rack 53 is driven to rotate, which in turn causes the rotating rod 54 to rotate. In conjunction with the work of the rotating motor 40, the rotating shaft 46 is driven to rotate, thereby allowing the two antenna rods 55 to adjust the signal receiving angle. When the rotating motor 40 rotates, the limit plate 45 should disengage from the rotating shaft 46.
[0066] The enclosure 51 encloses the rotating motor, which reduces the interference of the rotating motor to the signal. In conjunction with the arrangement of the hub 60 away from the rotating motor 40, it also greatly reduces the interference of the rotating motor 40 to the signal in the transmission line.
[0067] For any parts not mentioned in this utility model, existing technologies can be used or referenced.
[0068] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
[0069] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
