Description

Technical Field

[0001] The invention relates to the technical field of antenna focusing adjustment, and in particular to an adjustment device for a microwave near-field focusing antenna. Background Art

[0002] A microwave near-field focusing antenna is an antenna specially designed to focus microwave energy in a specific near-field area. This type of antenna has a wide range of applications in many fields, including microwave millimeter-wave imaging systems, wireless energy transmission systems, access control systems, radio frequency identification systems, and microwave radio systems. With the rapid development of wireless communications and network technology, microwave near-field focusing antennas will be used in more fields. In the future, researchers will continue to work hard to improve antenna performance, reduce costs, and achieve miniaturization and integration to meet the growing application needs. At the same time, with the continuous emergence of new materials and new technologies, the design and implementation of microwave near-field focusing antennas will also usher in more innovation and development opportunities.

[0003] Microwave near-field focusing antennas, with their unique energy focusing characteristics, have shown wide application potential in many key fields such as non-destructive testing, precise target identification, and modern communications. However, traditional antennas are unable to cope with these complex application scenarios. Their lack of focusing ability, environmental adaptability, and adjustment performance have become bottlenecks restricting their further development. First, in terms of focusing ability, traditional antennas often find it difficult to achieve the high-precision, high-intensity energy concentration effect of microwave near-field focusing antennas. This is mainly because the structural design and material selection of traditional antennas limit their improvement in focusing efficiency, making them inadequate in applications that require high energy density focusing. Secondly, environmental adaptability is also a bottleneck for traditional antennas. A major shortcoming of antennas is that in actual applications, the working environment of antennas is often complex and changeable. Various factors including temperature, humidity, electromagnetic interference, etc. may affect their performance. Traditional antennas are often difficult to fully consider these environmental factors during design, resulting in large performance fluctuations in actual use, making it difficult to meet stable and reliable working requirements. Finally, the lack of adjustment performance also limits the widespread application of traditional antennas in complex application scenarios. Traditional antennas often have limitations in adjustment performance, such as limited adjustment range, low adjustment accuracy, and complex adjustment process. These problems make it difficult for traditional antennas to quickly and accurately adjust their working status when facing different working scenarios and needs, thereby affecting the overall application effect.

[0050] Embodiment 3

[0051] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Fig.10As shown, the transport mechanism 1 includes a conveying plate 11, and the top of the conveying plate 11 is fixedly installed with the bottom of the base frame 21 near the edge, the top of the conveying plate 11 is provided with two notches 111, the top of the conveying plate 11 is fixedly connected with a linkage assembly 12 near the edge, the bottom of the conveying plate 11 is fixedly connected with a guide wheel 13, the outer wall of the conveying plate 11 is fixedly connected with four mounting frames 14, the bottom center of the inner wall of the four mounting frames 14 is provided with a hole 141, the inner wall of the four mounting frames 14 is fixedly inserted with a cylinder A15, and the telescopic ends of the four cylinders A15 are fixedly connected with a support plate 16;

[0052] The telescopic mechanism 2 includes a base frame 21, to which an electric telescopic rod 22 is fixedly connected at the top center of the base frame 21, to which a driving seat 23 is fixedly connected at the telescopic end thereof, and a driving annular plate 24 is movably rotatably provided on the inner surface wall of the driving seat 23, and a tooth groove 241 is provided on the inner surface wall of the driving annular plate 24, and a gear A25 is meshingly connected to the inner surface wall of the tooth groove 241, and a driving motor 26 is fixedly connected to the bottom of the gear A25, and an inner fixed plate 27 is fixedly sleeved on the outer surface wall of the driving motor 26, and the outer surface wall of the inner fixed plate 27 is fixedly connected to the inner surface wall of the telescopic end of the electric telescopic rod 22, and an adjusting seat A28 is fixedly connected to the top of the driving annular plate 24.

[0053] In this embodiment, first, when the equipment needs to be moved, it is necessary to connect the external vehicle with the linkage component 12, and then, under the pull of the vehicle, the transportation mechanism 1 can be driven to move. When the device is moved to a suitable position, the four cylinders A15 are then started, which can push the four support plates 16 to move downward and maintain contact with the ground, so that the conveying plate 11 and the components fixed on its top can be supported to keep the equipment in a stable state.

[0054] The working principle of the entire mechanism is as follows: when the equipment needs to be moved, the external vehicle must first be firmly connected to the linkage component 12, and then the traction of the vehicle is used to drive the transport mechanism 1 to move smoothly to the predetermined position. Once in place, the four cylinders A15 are activated to push the support plate 16 to slowly descend until it is in close contact with the ground, effectively supporting the conveying plate 11 and the fixed components above it to ensure that the equipment is stable and does not shake. Next, the flexible telescopic characteristics of the electric telescopic rod 22 are used to adjust the height of its top and the connecting components to meet different operating requirements.

When the drive motor 26 drives the gear A25 to rotate, the gear and the tooth groove 241 are precisely engaged, driving the drive annular plate 24 to rotate smoothly in the drive seat 23, thereby adjusting the direction of the antenna body 39. In order to achieve the tilt adjustment of the antenna body 39, the frequency converter accurately controls the two rotating motors A32 to rotate synchronously. The gear B33 of the rotating motor A32 is driven by the linkage rod 35 and the gear The continuous transmission of D36 eventually drives the rotating disk 37 to rotate, and the linkage frame 38 rotates longitudinally accordingly, so as to flexibly adjust the inclination angle of the antenna body 39. After the angle adjustment is completed, the two cylinders B42 use their telescopic function to push the linkage plate 43 to move horizontally in the fixed frame 41, and the locking plate 44 on the top of the linkage plate 43 approaches the gear C34, and the locking groove 441 is accurately inserted into the gear C34, effectively locking the gear C34, and keeping the inclination angle of the antenna body 39 stable. The focusing mechanism 5 is cleverly installed at the bottom center of the inner wall of the antenna body 39. When working, the rotating motor B52 converts electrical energy into a magnetic field to drive the rotor and the threaded rod 53 fixed thereon to rotate. Under the close cooperation between the threaded rod 53 and the threaded groove 551, combined with the smooth sliding of the slide plate 54 in the moving groove 512, the U-shaped plate 56 and the high-frequency head body 57 are adjusted up and down, and the distance between them and the antenna body 39 is finely adjusted to optimize the focusing effect and signal reception quality. This adjustment process needs to be fine-tuned according to the actual application scenario to achieve the best performance.
