Abstract
Description
Technical Field
[0001] This utility model relates to the field of antennas, and more specifically to a microwave antenna adjustment device. Background Technology
[0002] In wireless communication systems, the base station antenna serves as the interface between the transceiver and the external propagation medium. To adjust the beam radiation direction of the base station antenna, current technology typically employs a motor-driven transmission device to control the displacement of phase shifter elements within each unit of the antenna, thereby adjusting the beam angle. However, this method cannot adjust the tilt angle of the microwave antenna by adjusting the height of one side of the antenna. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model provides a microwave antenna adjustment device that can adjust the height of one side of the microwave antenna to achieve the adjustment of the tilt angle of the microwave antenna.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A microwave antenna adjustment device includes a support frame, a rotating frame fixedly connected to the support frame, a rotating frame rotatably connected between the support frame and the rotating frame, a pair of fixed frames and a pair of adjustment frames fixedly connected to the rotating frame, a rotating shaft rotatably connected to the pair of fixed frames, a mounting plate for mounting a microwave antenna fixedly connected to the rotating shaft, and a cam rotatably connected to the pair of adjustment frames to push the mounting plate to move.
[0006] Furthermore, a geared motor I that drives the cam to rotate is fixedly connected to one of the pair of adjustment frames.
[0007] Furthermore, the lower part of the support frame is fixed with multiple evenly distributed bottom legs.
[0008] Furthermore, a gear ring is fixedly connected to the rotating frame, and multiple extension plates are fixedly connected to the side of the support frame. Each extension plate is rotatably connected to a side wheel that meshes with and drives the gear ring to rotate.
[0009] Furthermore, each of the extended plates is fixedly connected to a reduction motor II that drives its corresponding side wheel to rotate.
[0010] The beneficial effects of this microwave antenna adjustment device are: it can adjust the height of one side of the microwave antenna to adjust the tilt angle of the microwave antenna; it can also drive the microwave antenna to rotate to adjust the orientation of the microwave antenna.

[0017] In the figure: support frame 11; bottom leg 12; slewing frame 13; outer extension plate 14; side wheel 15; geared motor II 16; rotating frame 21; gear ring 22; fixed frame 23; adjusting frame 24; cam 31; geared motor I 32; mounting plate 41; rotating shaft 42; guide tube 43. Detailed Implementation
[0018] refer to Figure 1 , 2 Examples 3, 4, and 5 detail the implementation methods for adjusting the orientation of the microwave antenna:
[0019] A microwave antenna adjustment device includes a support frame 11, on which a rotating frame 13 is fixedly connected. The rotating frame 13 is a limiting frame. A rotating frame 21 is rotatably connected between the support frame 11 and the rotating frame 13. Under the limitation of the rotating frame 13, the rotating frame 21 can only rotate around its own axis. A pair of fixed frames 23 and a pair of adjusting frames 24 are fixedly connected to the rotating frame 21. The pair of fixed frames 23 and the pair of adjusting frames 24 are symmetrically arranged. A rotating shaft 42 is rotatably connected to the pair of fixed frames 23. The rotating shaft 42 can rotate around its own axis. A mounting plate 41 for mounting a microwave antenna is fixedly connected to the rotating shaft 42. A cam 31 for pushing the mounting plate 41 is rotatably connected to the pair of adjusting frames 24. A reduction motor I 32 for driving the cam 31 to rotate is fixedly connected to one of the pair of adjusting frames 24. When the geared motor I32 is started, the output shaft of the geared motor I32 drives the cam 31 to rotate. As the cam 31 rotates, it supports one side of the upper mounting plate 41 at different positions. The different distances from the edge of the cam 31 to the rotation axis achieve different heights of support on one side of the mounting plate 41. In conjunction with the support of the rotating shaft 42 on the other side of the mounting plate 41, the mounting plate 41 is rotated, thereby adjusting the tilt angle of the mounting plate 41, and thus adjusting the tilt angle of the microwave antenna. In conjunction with the rotation of the rotating frame 21 around its own axis, the orientation of the microwave antenna at different positions is adjusted.
[0020] refer to Figure 2 and 5 Detailed examples of installing microwave antennas:
[0021] The lower part of the support frame 11 is fixedly connected to a plurality of evenly distributed base legs 12, thereby fixing the position of the microwave antenna by means of the plurality of base legs 12.
[0022] refer to Figure 4 and 5 Detailed implementation of an example for driving the rotation adjustment of a microwave antenna:
[0023] A gear ring 22 is fixedly connected to the rotating frame 21, and multiple extension plates 14 are fixedly connected to the side of the support frame 11. Each extension plate 14 is rotatably connected to a side wheel 15 that meshes with and drives the gear ring 22. Each extension plate 14 is fixedly connected to a reduction motor II 16 that drives its corresponding side wheel 15 to rotate. When the multiple reduction motors II 16 are started, they rotate synchronously. The output shafts of the multiple reduction motors II 16 drive the multiple side wheels 15 to rotate synchronously. The multiple side wheels 15 mesh with and drive the gear ring 22 to rotate, thereby realizing the rotation of the rotating frame 21 and thus realizing the adjustment of the microwave antenna orientation. The multiple side wheels 15 rotate synchronously in both forward and reverse directions. This allows for adjustment of the microwave antenna orientation in two directions, enabling reciprocating adjustment of the microwave antenna orientation and increasing the convenience of adjusting the microwave antenna orientation.
[0024] refer to Figure 1 , 2 Sections 4 and 5 detail embodiments of the guided microwave antenna wires:
[0025] A guide tube 43 is threadedly connected to the center of the mounting plate 41. A through hole corresponding to the guide tube 43 is provided in the center of the support frame 11. The microwave antenna wire extends downward through the guide tube 43 and downward through the through hole in the center of the support frame 11, thereby enabling the connection of the microwave antenna wire.
[0026] refer to Figure 2 and 3 Detailed description of embodiments to prevent the mounting plate 41 from accidentally slipping off:
[0027] The geared motor I32 is equipped with a brake to prevent the output shaft of the geared motor I32 from slipping, and to prevent the cam 31 from rotating unexpectedly, which would affect the stability of the mounting plate 41.
[0028] refer to Figure 2 Detailed description of an embodiment of the support mounting plate 41:
[0029] The axis of the rotating shaft 42 is higher than the axis of rotation of the cam 31, so the height of the support mounting plate 41 can be adjusted by the distance from the edge of the cam 31 to the axis of rotation, thereby adjusting the tilt angle of the mounting plate 41 and realizing the adjustment of the orientation of the microwave antenna.
