Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to an antenna rotating frame. Background Technology

[0002] In fields such as antenna communication and detection, antenna swivel mounts are key devices for enabling multi-angle antenna adjustment to adapt to different signal transmission and reception needs, and their performance directly affects the stability and efficiency of signal transmission. However, existing antenna swivel mounts often have many limitations: most can only achieve single-dimensional or limited-range adjustment, such as simple pitch or height adjustment, which is insufficient to meet the needs of multi-dimensional, high-precision antenna rotation and positioning in complex scenarios; the connection method of the rotation mechanism is relatively simple, often resulting in swaying or offset during rotation due to high frictional resistance and insufficient structural stability, leading to low positioning accuracy and affecting the accuracy of signal reception or transmission; at the same time, the installation and fixing of signal transmission-related components (such as adapters, couplers, etc.) lacks a precise positioning structure, which can easily lead to increased signal transmission loss and decreased stability due to installation misalignment; in addition, most existing swivel mounts do not integrate necessary signal processing components, requiring additional external local oscillator amplifiers, mixers, power amplifiers, etc., which not only increases the overall complexity and deployment difficulty of the system, but may also further reduce signal processing efficiency due to excessively long signal transmission paths, making it difficult to adapt to high-precision, high-efficiency antenna operating scenarios. Utility Model Content

[0003] The purpose of this invention is to provide an antenna rotating bracket that solves the above-mentioned problems.

[0004] This utility model is achieved through the following technical solution:

[0005] An antenna rotating frame includes a bottom lift and an elevation platform movably connected to the top of the lift. It also includes an antenna rotation mechanism disposed on the side of the elevation platform. The antenna rotation mechanism includes a mounting frame, a rotating platform, a selector, a mounting base, a fixing component, a waveguide coaxial adapter, a directional coupler, and a standard gain horn antenna. The mounting frame is vertically mounted on the side of the elevation platform. One end of the rotating platform is fixedly connected to the mounting frame, and the other end of the rotating platform is connected to the selector. The selector is fixedly connected to the mounting base. The waveguide coaxial adapter is fixed at the center of the mounting base via a fixing component. The other end of the waveguide coaxial adapter is connected to the input end of the directional coupler, and its output end is connected to the standard gain horn antenna.

[0006] Furthermore,

[0007] The rotating platform includes a fixed end and a rotating end. The fixed end is fixedly connected to the side of the mounting frame away from the pitch platform, and the axis of the rotating platform is perpendicular to the axis of the column of the pitch platform. The rotating end is connected to the fixed end and the selector is coaxial with the rotating platform.

[0008] Furthermore,

[0009] One end of the fastener is detachably connected to the mounting platform by bolts, and the other end has a positioning groove that matches the outer diameter of the waveguide coaxial adapter.

[0010] Furthermore,

[0011] The waveguide-coaxial adapter includes a waveguide interface and a coaxial interface. The waveguide interface is fixedly connected to the waveguide port of the directional coupler through a flange, and the coaxial interface is coaxially aligned with the center hole of the fixing component.

[0012] Furthermore,

[0013] The directional coupler includes a main transmission channel and a coupling channel. The input end of the main transmission channel is connected to a waveguide coaxial adapter, and the output end of the coupling channel is connected to a standard gain horn antenna.

[0014] Furthermore,

[0015] The standard gain horn antenna is detachably connected to the output end of the directional coupler via a threaded interface, and the axis of the threaded interface coincides with the axis of the waveguide coaxial adapter.

[0016] Furthermore,

[0017] The elevator is also equipped with a local oscillator amplifier and a reference mixer on its sides.

[0018] Furthermore,

[0019] Power amplifiers are also installed on the sides of the elevation platform.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model achieves multi-dimensional and all-round adjustment functions of the antenna through the coordinated design of the bottom lifting platform, the elevation platform and the antenna rotation mechanism. The lifting platform can flexibly adjust the overall height, the elevation platform can accurately control the elevation angle, and the rotation of the rotating platform around the column axis and the rotation of the mounting platform around its own axis further expand the horizontal and axial rotation range. The multi-dimensional adjustment capability enables it to adapt to the signal transmission and reception requirements and polarization direction stability in different scenarios, greatly improving the environmental adaptability of the equipment.

[0022] 2. The rotating platform and the elevation platform are connected coaxially by bearings, which not only significantly reduces frictional resistance during rotation, ensuring smooth and stable rotation and reducing mechanical wear to extend the service life of the equipment; but also avoids swaying or offset caused by eccentricity through the design of the rotation axis and the column axis, effectively improving the rotation positioning accuracy and providing a structural basis for the antenna to accurately capture or transmit signals under complex working conditions.

[0023] 3. Flange connection ensures the sealing of signal transmission and reduces leakage loss; the coaxial design of multiple components avoids the distortion or offset of the signal transmission path, reduces reflection and refraction loss, and significantly improves the stability and efficiency of signal transmission.

[0024] 4. The local oscillator amplifier and reference mixer integrated on the side of the elevator, as well as the power amplifier set on the side of the elevation platform, realize the integrated layout of signal processing components and antenna adjustment structure, shorten the signal transmission path, and reduce external interference and transmission loss; at the same time, it saves the overall system space, simplifies the deployment process, and improves the efficiency of signal processing (such as oscillation reference provision, frequency conversion, and power enhancement), enabling the equipment to be directly adapted to high-precision and high-efficiency signal transmission and reception scenarios.

[0034] See the example. Figures 1 to 3 :

[0035] An antenna rotating frame includes a bottom lifting platform 1 and an elevation platform 2 movably connected to the top of the lifting platform 1. It also includes an antenna rotation mechanism 3 disposed on the side of the elevation platform 2. The antenna rotation mechanism 3 includes a mounting frame 30, a rotating platform 31, a selector 32, a mounting base 33, a fixing element 34, a waveguide coaxial adapter 35, a directional coupler 36, and a standard gain horn antenna 37. The mounting frame 30 is vertically mounted on the side of the elevation platform 2. One end of the rotating platform 31 is fixedly connected to the mounting frame 30, and the other side of the rotating platform 31 is connected to the selector 32. The selector 32 is fixedly connected to the mounting base 33. The waveguide coaxial adapter 35 is fixed at the center of the mounting base 33 via the fixing element 34. The other end of the waveguide coaxial adapter 35 is connected to the input end of the directional coupler 36, and its output end is connected to the standard gain horn antenna 37.

[0036] Furthermore,

[0037] The rotating platform 31 includes a fixed end 310 and a rotating end 311. The fixed end 310 is fixedly connected to the side of the mounting frame 30 away from the pitch platform 2, and the axis of the rotating platform 31 is perpendicular to the column axis of the pitch platform 2. The rotating end 311 is connected to the fixed end 310 and the selector 32 is coaxial with the rotating platform 31.

[0038] Furthermore,

[0039] One end of the fastener 34 is detachably connected to the mounting platform 33 by bolts, and the other end is provided with a positioning groove 340 that matches the outer diameter of the waveguide coaxial adapter 35.

[0040] The positioning slot 340 can precisely match the waveguide coaxial adapter 35, ensuring the accuracy of its installation position and avoiding signal transmission abnormalities caused by installation misalignment; the detachable design of the bolt connection not only ensures the stability of the fixation, but also facilitates quick disassembly and assembly when maintaining or replacing the waveguide coaxial adapter 35, improving the maintenance efficiency of the equipment.

[0041] Furthermore,

[0042] The waveguide-coaxial adapter 35 includes a waveguide interface and a coaxial interface. The waveguide interface is fixedly connected to the waveguide port of the directional coupler 36 through a flange, and the coaxial interface is coaxially aligned with the center hole of the fixing member 34.

[0043] The flange connection has high strength and sealing performance, which can ensure a tight connection between the waveguide interface and the waveguide port of the directional coupler 36, reducing signal leakage and loss during transmission; while the coaxial interface is coaxially aligned with the center hole of the fixing member 34, which can ensure the stability of the mounting axis of the waveguide coaxial adapter 35, avoid signal transmission path distortion caused by misalignment, and ensure the stability of signal conversion and transmission.

[0044] Furthermore,

[0045] The directional coupler 36 includes a main transmission channel and a coupling channel. The input end of the main transmission channel is connected to the waveguide coaxial adapter 35, and the output end of the coupling channel is connected to the standard gain horn antenna 37.

[0046] The main transmission channel is responsible for the efficient transmission of the main signal, ensuring the integrity of the core signal; the coupling channel can separate a portion of the signal from the main transmission channel and transmit it to the standard gain horn antenna 37, realizing the rational allocation and utilization of the signal. This structure not only ensures the stable transmission of the main signal, but also meets the signal requirements of the horn antenna through the coupling channel. At the same time, the directional characteristics can reduce mutual interference between signals and improve the overall signal transmission quality.

[0047] Furthermore,

[0048] The standard gain horn antenna 37 is detachably connected to the output end of the directional coupler 36 via a threaded interface, and the axis of the threaded interface coincides with the axis of the waveguide coaxial adapter 35.

[0049] The detachable design of the threaded interface makes it easy to replace the standard gain horn antenna 37 of different specifications according to actual needs, enhancing the flexibility of the equipment; while the coincident axis ensures that the signal transmission path from the waveguide coaxial adapter 35 through the directional coupler 36 to the horn antenna is straight, reducing the reflection, refraction or loss of the signal during transmission, ensuring the gain stability of the horn antenna, and improving the signal transmission and reception efficiency.

[0050] Furthermore,

[0051] The elevator 1 is also equipped with a local oscillator amplifier 4 and a reference mixer on its side.

[0052] The local oscillator amplifier 4 provides a stable local oscillation signal, serving as a reference for signal frequency conversion processing; the reference mixer is used to perform frequency mixing processing on the signal, realizing signal frequency conversion. Placing both on the side of the elevator 1 shortens the physical distance to the antenna system, reduces interference and loss during signal transmission, and the integrated design saves equipment space, facilitates overall layout, and improves the system's signal processing efficiency.

[0053] Furthermore,

[0054] Power amplifiers 6 are also installed on the sides of the elevation platform 2.

[0055] The power amplifier 6 can amplify the power of the signals transmitted and received by the antenna, enhance the signal strength, and ensure that the signal can maintain good quality when transmitted over long distances. By placing it on the side of the elevation platform 2, close to the standard gain horn antenna 37, the signal transmission path can be shortened, the power loss during transmission can be reduced, and the actual working performance of the antenna can be improved. It is especially suitable for scenarios that require strong signal coverage or long-distance communication.

[0056] The method of using this utility model is as follows:

[0057] The antenna rotation mount achieves precise adjustment and efficient signal transmission through the collaborative operation of multiple components. Its use and principle are closely integrated: the bottom lifting platform 1 can flexibly adjust the overall height, providing a basic height adaptation for signal transmission and reception in different scenarios; the elevation platform 2 can precisely control the elevation angle, working with the antenna rotation mechanism 3 to achieve multi-angle coverage. In the antenna rotation mechanism 3, the mounting bracket 30 is vertically fixed to the side of the elevation platform 2, the fixed end 310 of the rotating platform 31 is connected to the mounting bracket 30, and the rotating end 311 drives the selector 32 and the mounting platform 33 to rotate around their own axis. The axis of the rotating platform 31 is perpendicular to the axis of the column of the elevation platform 2, realizing multi-dimensional rotation in both horizontal and axial directions, meeting the positioning requirements in complex scenarios. The rotating platform 31 and the elevation platform 2 are connected by bearings, which greatly reduces frictional resistance, ensures stable rotation, and improves positioning accuracy.

[0058] During signal transmission, the fixing component 34 at the center of the mounting platform 33 precisely fixes the waveguide coaxial adapter 35 through the positioning slot 340. Its waveguide interface is connected to the waveguide port flange of the directional coupler 36 to ensure sealing and reduce loss. The coaxial interface is coaxially aligned with the center hole of the fixing component 34 to avoid signal path deviation. The main transmission channel of the directional coupler 36 efficiently transmits signals, while the coupling channel transmits part of the signal to the standard gain horn antenna 37. The horn antenna is connected to the coupler through a threaded interface, and its axis coincides with the adapter to reduce signal reflection and refraction loss. At the same time, the local oscillator amplifier 4 on the side of the elevator 1 provides a stable oscillation reference, the reference mixer realizes frequency conversion, and the power amplifier 6 on the side of the elevation platform 2 enhances the signal strength. The integrated design shortens the signal transmission path and reduces interference and loss, ultimately achieving multi-dimensional precise adjustment and efficient and stable signal transmission and reception, adapting to various complex working conditions.
