Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to antenna communication equipment, especially an antenna mast device with remotely controllable and adjustable azimuth. Background Technology

[0002] Communication antenna equipment is installed on communication towers to transmit wireless signals. In the existing technology, some special high-capacity communication antenna equipment used in wireless communication engineering (such as lens split antennas) does not have azimuth angle electronic control adjustment function and cannot remotely adjust the azimuth angle in real time. Within the coverage area of ​​this type of antenna, as time goes by, when the location of a large number of target users changes regularly, the inability to remotely control the azimuth angle in real time will objectively reduce the working efficiency of the equipment and reduce the wireless coverage effect. Summary of the Invention

[0003] The purpose of this invention is to provide an antenna mast device with remotely controllable azimuth adjustment, which solves the technical problem that existing communication antenna devices cannot achieve remote electronic control adjustment of azimuth angle.

[0004] This invention discloses a remotely controllable and adjustable antenna mast device, comprising an upper support frame and a lower support frame. The upper support frame is located above the lower support frame. Each of the upper and lower support frames has a clamp connected to one side. A fixed post is provided on the bottom surface of the upper support frame, and a rotating sleeve is fitted onto the fixed post. An axial limiting structure is provided between the rotating sleeve and the fixed post, forming a circumferential rotating pair. The lower side of the rotating sleeve is connected to the first end of a first universal joint, and the second end of the first universal joint is connected to the upper end of a mast. A communication antenna device is connected to the mast. A protective cover is connected to the lower support frame. A slide rail is provided, on which a slide block is mounted. A first drive device is mounted on the slide block. The power output end of the first drive device is connected to the first end of a second universal joint. A telescopic rod is coaxially connected to the lower end face of the support rod. The lower end of the telescopic rod is connected to the second end of the second universal joint. A second drive device is provided in the lower support frame. The power output end of the second drive device is connected to the first end of a lead screw. A threaded hole is provided on the side of the slide block. The second end of the lead screw is connected to the threaded hole. The control ends of the first drive device and the second drive device are respectively connected to a controller via wires.

[0005] Furthermore, the first driving device and the second driving device are respectively a first servo motor and a second servo motor, and each of the first servo motor and the second servo motor is connected to a power failure brake.

[0006] Compared with existing technologies, the advantages of this invention are positive and significant. This invention utilizes a controller for remote control. A second servo motor, via a lead screw, moves a slide along a guide rail, thereby adjusting the vertical azimuth angle of the communication antenna equipment. A first servo motor drives the mast to rotate, thus adjusting the horizontal azimuth angle of the communication antenna equipment. A power-off brake automatically locks the motor shaft after a power outage, achieving azimuth angle locking and preventing azimuth angle drift caused by external forces on the antenna equipment and mast. The controller integrates motor drive and communication modules, enabling remote control of motor start / stop and real-time recording of servo motor motion parameters, achieving remote control adjustment of the azimuth angle. This invention addresses communication antenna equipment lacking electric azimuth adjustment by providing real-time mechanical adjustment of the horizontal and vertical azimuth angles through remote control. This compensates for the reduced network coverage efficiency caused by equipment defects in existing technologies, contributing to network coverage optimization and improving the network coverage effect of wireless devices.

[0010] like Figure 1 and Figure 2As shown, an antenna mast device with remotely controllable azimuth adjustment according to the present invention includes an upper support frame 1 and a lower support frame 2. The upper support frame 1 is located above the lower support frame 2. A clamp 3 is connected to one side of each of the upper support frame 1 and the lower support frame 2. A fixed post 4 is provided on the bottom surface of the upper support frame 1. A rotating sleeve 5 is sleeved on the fixed post 4. An axial limiting structure is provided between the rotating sleeve 5 and the fixed post 4, forming a circumferential rotating pair. The lower side of the rotating sleeve 5 is connected to the first end of a first universal joint 6. The second end of the first universal joint 6 is connected to the upper end of a mast 7. A communication antenna device 8 is connected to the mast 7. A protective cover 9 is connected to the lower support frame 2. A slide rail 10 is provided in the protective cover 9. A slide block 11 is provided on the slide rail 10, and a first drive device 12 is provided on the slide block 11. The power output end of the first drive device 12 is connected to the first end of a second universal joint 13. A telescopic rod 14 is coaxially connected to the lower end face of the support rod 7. The lower end of the telescopic rod 14 is connected to the second end of the second universal joint 13. A second drive device 15 is provided in the lower support frame 2. The power output end of the second drive device 15 is connected to the first end of a lead screw 16. A threaded hole is provided in the side of the slide block 11. The second end of the lead screw 16 is connected to the threaded hole. The control ends of the first drive device 12 and the second drive device 15 are respectively connected to a controller (not shown in the figure) through wires 18.

[0011] Furthermore, the first driving device 12 and the second driving device 15 are respectively a first servo motor and a second servo motor, and each of the first servo motor and the second servo motor is connected to a power failure brake.

[0012] Specifically, in this embodiment, the clamp 3, axial limiting structure, rotating joint, first universal joint 6, second universal joint 13, communication antenna equipment 8, first driving device 12, clamping rod 7, telescopic rod 14, second driving device 15, lead screw 16, controller, servo motor, power failure brake, etc., all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0013] The working principle of this embodiment:

[0014] According to the requirements of the wireless network, this device is installed on the communication tower 17 via the upper support frame 1, the lower support frame 2, and the clamp 3, and the initial azimuth angle of the communication antenna device 8 is set. Figure 1 As shown, three antenna masts 7 can be installed along the circumference of the communication tower 17. The masts 7 are used for the installation of the communication antenna equipment 8. The telescopic rod 14 and the first universal joint 6, the second universal joint 13 and other components are used to provide the masts 7 with the function of adapting to changes in length and joint angles when adjusting the horizontal and vertical azimuth angles.

[0015] When the vertical azimuth angle 19 of the communication antenna device 8 needs to be adjusted during use, the second servo motor starts working under the control of the controller, the power-off brake is energized, the braking state is released, the output shaft of the second servo motor rotates, driving the lead screw 16 to rotate, which in turn drives the slide 11 to move along the guide rail, thereby driving the mast 7 to rotate and adjust the vertical azimuth angle 19 of the communication antenna device 8. During the change of the vertical azimuth angle 19, the first universal joint 6 and the second lower universal joint adapt to the change of the joint angle, and the telescopic rod 14 adapts to the change of the mast 7 axis length caused by the change of the vertical azimuth angle 19. When the vertical azimuth angle 19 is adjusted, the second servo motor and its power-off brake are de-energized, the braking state is opened and the output shaft of the second servo motor is locked, thereby locking the vertical azimuth angle 19 of the communication antenna device 8 to prevent its angle from changing due to wind load or external forces during installation and maintenance.

[0016] After the vertical azimuth angle 19 is adjusted, the horizontal azimuth angle adjustment can be initiated. The horizontal azimuth angle servo system is powered on, and the output shaft of the first servo motor rotates, directly driving the mast 7 to rotate via the second universal joint 13. This causes a change in the horizontal azimuth angle of the communication antenna device 8. The first universal joint 6 and the revolute joint work together to adapt to the change in the rotation angle of the mast 7. Once the horizontal azimuth angle adjustment is complete, the second servo motor and its power-off brake are de-energized, the brake is engaged, and the output shaft of the second servo motor is locked, thereby locking the horizontal azimuth angle of the communication antenna device 8 and preventing changes in its azimuth angle due to various external forces. At this point, all azimuth angle adjustments of the antenna are complete.

[0017] The first servo motor and the second servo motor each form a closed-loop servo control system with the controller. The controller records and receives the rotation data of the first servo motor and the second servo motor back to the central office in real time, so as to realize remote control.

[0018] This invention utilizes a controller for remote control. A second servo motor, via a lead screw 16, moves a slide 11 along a guide rail, thereby adjusting the vertical azimuth angle 19 of the communication antenna device 8. A first servo motor drives the mast 7 to rotate, thus adjusting the horizontal azimuth angle of the communication antenna device 8. A power-off brake automatically locks the motor shaft after a power outage, achieving azimuth angle locking and preventing azimuth angle drift caused by external forces on the antenna device and mast 7. The controller integrates a motor drive and communication module, enabling remote control of motor start / stop and real-time recording of servo motor motion parameters, achieving remote control adjustment of the azimuth angle. This invention addresses communication antenna devices lacking electric azimuth adjustment by providing real-time mechanical adjustment of the horizontal and vertical azimuth angles via remote control. This compensates for the reduced network coverage efficiency caused by equipment defects in existing technologies, contributing to network coverage optimization and improving the network coverage effect of wireless devices.
