Description
Technical Field
[0001] This invention belongs to the field of base station antenna technology, specifically referring to an angle-adjustable base station antenna. Background Technology
[0002] Currently, most base station antennas have their azimuth and tilt angles fixed during initial installation. However, over time, natural factors such as strong winds and earthquakes, or environmental factors such as new construction or changes in terrain, can cause antenna angles to shift. Once the antenna angle deviates from the initial design value, it severely affects signal coverage and strength. When the azimuth angle deviation is too large, the originally planned signal coverage area will experience signal weakening or even dead zones. At the same time, signal interference between adjacent base stations will intensify, leading to a decline in communication quality, intermittent calls, and reduced data transmission rates. Furthermore, existing methods for adjusting base station antenna angles are extremely limited. Traditional manual adjustment requires technicians to climb to a high position with specialized measuring instruments. In adverse weather conditions (such as high temperatures, heavy rain, and strong winds), this is not only extremely difficult but also poses serious safety hazards. Summary of the Invention
[0003] To address the problems in the prior art, this invention proposes an angle-adjustable base station antenna, which allows for convenient adjustment of the antenna angle.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an angle-adjustable base station antenna, comprising an antenna body, a mounting bracket, an azimuth adjustment mechanism, a tilt angle adjustment mechanism, a control device, and an antenna mounting base; the antenna body is mounted on the antenna mounting base via the mounting bracket, and a plurality of antenna bodies are mounted on the antenna mounting base; the antenna body is used for signal transmission and reception; the azimuth adjustment mechanism is used to drive the antenna body to rotate and adjust the azimuth angle; the tilt angle adjustment mechanism is used to drive the antenna body to rotate and adjust the tilt angle; the control device is electrically connected to the azimuth adjustment mechanism and the tilt angle adjustment mechanism respectively, and the control device is used to control the operation of the azimuth adjustment mechanism and the tilt angle adjustment mechanism.
[0005] Furthermore, the mounting bracket includes a mounting plate and a movable plate. The bottom of the mounting plate is hinged to the bottom of the movable plate. The antenna body is mounted on the movable plate. The tilt angle adjustment mechanism adjusts the tilt angle of the antenna body by adjusting the angles of the mounting plate and the movable plate. The antenna mounting base includes a column, a mounting platform, and a mounting shaft. The mounting plate has two bearing seats on the side near the antenna mounting base. The bearing seats are equipped with rolling bearings. The mounting plate is mounted on the mounting shaft through the bearing seats. The azimuth angle adjustment mechanism adjusts the azimuth angle of the antenna body by adjusting the angle of the mounting plate.
[0006] Furthermore, the azimuth adjustment mechanism includes an azimuth adjustment motor, a first drive gear, and a fixed gear. The azimuth adjustment motor is mounted on the antenna mounting base. The azimuth adjustment motor drives the first drive gear through a first gear reducer. The fixed gear is fixedly mounted on one side of the bearing housing and is concentric with the rolling bearing of the bearing housing. The first drive gear meshes with the fixed gear.
[0007] Furthermore, the mounting platform has a turntable at its center, and a lifting platform is provided above the turntable. The azimuth adjustment motor is mounted on the lifting platform, and a steering gear is mounted on the shaft of the azimuth adjustment motor. A gear ring is also fixedly provided on the mounting platform. The gear ring is located outside the turntable and is concentric with the turntable. When the lifting platform is lowered, the steering gear meshes with the gear ring. A first electromagnetic push rod is fixed to the end of the shaft of the azimuth adjustment motor, and a magnetic suction plate is provided at the end of the push rod of the first electromagnetic push rod. The first drive gear is mounted on the output shaft of the first gear reducer, and the first drive gear meshes with the fixed gear. A metal plate is mounted on the input shaft of the first gear reducer. When the lifting platform is raised, the magnetic plate at the end of the first electromagnetic push rod is aligned with the height of the metal plate. When the push rod of the first electromagnetic push rod is pushed out, the magnetic plate is attracted to the metal plate.
[0008] Furthermore, a circular track is provided around the center of the mounting platform, and a slider that can slide along the circular track is provided on the circular track. A bracket is installed above the slider via a second electromagnetic push rod. The bracket is Y-shaped, and each of the two forks of the bracket is provided with a pulley. The bracket is connected to the lifting platform via connecting rods. There are two connecting rods. When the lifting platform rotates with the turntable, it synchronously drives the bracket to move through the connecting rods. The bracket is located below the first electromagnetic push rod, which is placed on the two pulleys. The lifting platform is driven to rise and fall by several third electromagnetic push rods. When the third electromagnetic push rod pushes the lifting platform to rise, the second electromagnetic push rods synchronously push the bracket to rise to the same height, so that the bracket supports the first electromagnetic push rod and prevents the first electromagnetic push rod from falling under the force of gravity, which would affect docking and transmission. When the second electromagnetic push rod rotates, the two pulleys reduce friction.
[0009] Furthermore, the first electromagnetic push rod is provided with two conductive metal rings on its outer side, and the two conductive metal rings are respectively connected to the positive and negative poles of the first electromagnetic push rod. The bracket is provided with two power supply brushes. When the first electromagnetic push rod rotates under the drive of the azimuth adjustment motor, the two power supply brushes respectively contact the two conductive metal rings.
[0010] Furthermore, the tilt angle adjustment mechanism includes a tilt angle adjustment motor, a second drive gear, and an arc-shaped plate. The tilt angle adjustment motor and the second drive gear are mounted on the top of the mounting plate. The tilt angle adjustment motor drives the second drive gear to rotate via a second gear reducer. The center of the arc-shaped plate coincides with the axis of rotation of the movable plate. The arc-shaped plate is provided with an arc-shaped rack, which meshes with the second drive gear. The tilt angle adjustment motor drives the second drive gear to rotate, the second drive gear pushes the arc-shaped plate to move, and the arc-shaped plate drives the movable plate and the antenna body to rotate, thereby changing the tilt angle of the antenna body.
[0011] Furthermore, the arc-shaped plate is provided with an arc-shaped slot, the arc-shaped rack is located on one side of the arc-shaped slot, and a limiting roller is also provided below the second drive gear, the limiting roller abutting against the other side of the arc-shaped slot. This prevents the arc-shaped rack from disengaging from the second drive gear.
[0012] Furthermore, the control device includes an angle sensor and a controller. The azimuth adjustment motor, the tilt adjustment motor / the angle sensor, the first electromagnetic push rod, the second electromagnetic push rod, and the third electromagnetic push rod are all electrically connected to the controller. The angle sensor is a gyroscope, and there are two angle sensors, respectively located on the mounting plate and the movable plate. The two angle sensors are used to detect the azimuth and tilt angles of the antenna body in real time and transmit the detection data to the controller. The controller controls the operation of the azimuth adjustment mechanism and the tilt adjustment mechanism according to preset angle parameters and the detection data of the angle sensors. The controller is equipped with a storage unit for storing historical antenna angle data measured by the angle sensors, which facilitates staff to query historical data and can be used to trace the time of failure in case of failure for easy analysis. The control device also includes a communication module, which connects to a cloud server. The communication module uploads the historical antenna angle data stored in the storage unit to the cloud server at preset time intervals.
[0013] Furthermore, the cloud server is equipped with an authentication module, a data backup module, an automatic adjustment threshold setting module, and an active adjustment module. Staff can log in to the cloud server via a mobile app. The authentication module verifies the staff's identity and confirms whether the logged-in user has the authority to browse information, modify settings, actively adjust antenna angles, and upload user feedback. The data backup module backs up and stores the antenna angle data uploaded by the communication module. The automatic adjustment threshold setting module allows staff to set automatic adjustment thresholds for the azimuth and tilt angles. When the error between the measured antenna azimuth or tilt angle and the angle value set by the active adjustment module exceeds the automatic adjustment threshold set by the staff, the controller automatically adjusts the antenna angle. The active adjustment module allows staff to actively adjust the antenna angle, enabling remote adjustment without the need for on-site personnel. It also includes a user feedback module for users to upload feedback. For antennas in areas with abnormal communication quality reported by users, historical antenna angle data can be checked to determine if a misalignment has caused the fault. The controller is equipped with an automatic detection interval adjustment unit, which adjusts the data acquisition interval of the angle sensor according to the automatic adjustment threshold sent by the cloud server, reducing energy consumption.
[0014] The beneficial effects of the angle-adjustable base station antenna of the present invention are as follows: 1. By setting an angle sensor, the azimuth and tilt angle deviations of the antenna can be monitored in real time. When a deviation is detected and the angle needs to be corrected, the azimuth and tilt angles of the antenna body are corrected by the azimuth adjustment mechanism and the tilt adjustment mechanism, effectively maintaining the signal coverage and strength, and solving the angle deviation problem caused by natural factors and environmental changes. 2. The azimuth adjustment mechanism's azimuth adjustment motor drives the first drive gear through a first gear reducer. The first drive gear meshes with a fixed gear fixed on one side of the bearing seat. The reduction effect of the gear reducer can convert the high-speed rotation of the motor into a low-speed, high-torque output. Combined with the precise meshing between the gears, it realizes the micro-angle adjustment of the mounting plate around the mounting shaft, thereby realizing the azimuth adjustment of the antenna body. The tilt adjustment mechanism drives the second drive gear to rotate through a second gear reducer via a tilt adjustment motor. The rotation of the second drive gear meshes with the arc-shaped rack on the arc plate. When the second drive gear rotates, it can drive the arc plate to move. The arc plate pulls the movable plate to rotate around the hinge, thereby realizing the tilt angle adjustment of the antenna body. 3. The control device connects to the cloud server via a communication module. Staff can remotely and actively view or adjust the antenna angle by logging into the cloud server via mobile phone or computer, without having to climb to a high place, thus reducing operational safety hazards; 4. The controller's storage unit and cloud server data backup module can record historical antenna angle data, facilitating traceability and analysis in case of faults; 5. A limiting roller is provided to abut one side of the arc-shaped slot to prevent the second drive gear from disengaging from the arc-shaped rack, ensuring the stable and reliable operation of the tilt angle adjustment mechanism; 6. By meshing the steering gear on the shaft of the azimuth adjustment motor with the gear ring fixedly mounted on the mounting platform, the azimuth adjustment motor can drive itself and the turntable to rotate when it starts, changing the orientation of the azimuth adjustment motor shaft. The orientation is adjusted to align with the antenna body that needs to be adjusted. Only one motor can be used to adjust the azimuth of multiple antenna bodies on the antenna mounting base. 7. By setting up a lifting platform, when the azimuth adjustment motor is raised, the meshing of the steering gear and the gear ring can be separated, realizing the function switching of the azimuth adjustment motor, and aligning the magnetic suction plate at the end of the first electromagnetic push rod with the metal plate installed on the shaft of the first gear reducer. 8. By setting a first electromagnetic push rod, the magnetic plate can be pushed towards the metal plate, connecting the magnetic plate and the metal plate. When the azimuth adjustment motor starts, the azimuth adjustment motor drives the first electromagnetic push rod to rotate. The first electromagnetic push rod drives the metal plate to rotate through the magnetic plate. The metal plate is installed on the input shaft of the first gear reducer. The first drive gear on the output shaft of the first gear reducer also starts to rotate. The first drive gear drives the fixed gear and the mounting plate to rotate around the mounting shaft, realizing the azimuth adjustment function. Attached Figure Description

Detailed Implementation
[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1: As Figure 1-3 As shown, this invention relates to an angle-adjustable base station antenna, comprising an antenna body 1, a mounting bracket 2, an azimuth adjustment mechanism 3, a tilt angle adjustment mechanism 4, a control device 5, and an antenna mounting base 6. The antenna body 1 is mounted on the antenna mounting base 6 via the mounting bracket 2. A plurality of antenna bodies 1 are mounted on the antenna mounting base 6. The antenna body 1 is used for signal transmission and reception. The azimuth adjustment mechanism 3 is used to drive the antenna body 1 to rotate and adjust the azimuth angle. The tilt angle adjustment mechanism 4 is used to drive the antenna body 1 to rotate and adjust the tilt angle. The control device 5 is electrically connected to the azimuth adjustment mechanism 3 and the tilt angle adjustment mechanism 4, respectively, and is used to control the operation of the azimuth adjustment mechanism 3 and the tilt angle adjustment mechanism 4. Multiple mounting brackets 2 can be mounted on the antenna mounting base 6, and each mounting bracket 2 has an antenna body 1 mounted on it.
[0019] Further, the mounting bracket 2 includes a mounting plate 21 and a movable plate 22. The bottom of the mounting plate 21 is hinged to the bottom of the movable plate 22. The antenna body 1 is mounted on the movable plate 22. The tilt angle adjustment mechanism 4 adjusts the tilt angle of the antenna body 1 by adjusting the angle of the mounting plate 21 and the movable plate 22. The antenna mounting base 6 includes a column 61, a mounting platform 62, and a mounting shaft 63. The mounting platform 62 is fixed to the top of the column 61. Several mounting shafts 63 are installed at equal angles around the axis of the column 61 on each mounting platform 62. The mounting bracket 2 is mounted on the mounting shaft 63. The mounting plate 21 has two bearing seats 211 on the side near the antenna mounting base 6. The bearing seats 211 are equipped with rolling bearings. The mounting plate 21 is mounted on the mounting shaft 63 through the bearing seats 211. The azimuth angle adjustment mechanism 3 adjusts the azimuth angle of the antenna body 1 by adjusting the angle of the mounting plate 21.
[0020] Furthermore, the azimuth adjustment mechanism 3 includes an azimuth adjustment motor 31, a first drive gear 32, and a fixed gear 33. The azimuth adjustment motor 31 is mounted on the antenna mounting base 6. The azimuth adjustment motor 31 drives the first drive gear 32 through a first gear reducer 8. The fixed gear 33 is fixedly mounted on one side of the bearing housing 211, and the fixed gear 33 is concentric with the rolling bearing of the bearing housing 211. The first drive gear 32 meshes with the fixed gear 33.
[0021] Furthermore, the tilt angle adjustment mechanism 4 includes a tilt angle adjustment motor 41, a second drive gear 42, and an arc-shaped plate 43. The tilt angle adjustment motor 41 and the second drive gear 42 are mounted on the top of the mounting plate 21. The tilt angle adjustment motor 41 drives the second drive gear 42 to rotate via a second gear reducer 9. The center of the arc-shaped plate 43 coincides with the axis of rotation of the movable plate 22. The arc-shaped plate 43 is provided with an arc-shaped rack 432, which meshes with the second drive gear 42. The tilt angle adjustment motor 41 drives the second drive gear 42 to rotate, the second drive gear 42 pushes the arc-shaped plate 43 to move, and the arc-shaped plate 43 drives the movable plate 22 and the antenna body 1 to rotate, thereby changing the tilt angle of the antenna body 1.
[0022] Furthermore, the arc-shaped plate 43 is provided with an arc-shaped slot 431, and the arc-shaped rack 432 is provided on one side of the arc-shaped slot 431. A limiting roller 44 is also provided below the second drive gear 42, and the limiting roller 44 abuts against the other side of the arc-shaped slot 431 to prevent the arc-shaped rack 432 from disengaging from the second drive gear 42.
[0023] Furthermore, the control device 5 includes an angle sensor 51 and a controller 52. The azimuth adjustment motor 31, the tilt adjustment motor 41, and the angle sensor 51 are all electrically connected to the controller 52. The angle sensor 51 is a gyroscope. There are two angle sensors 51, which are respectively installed on the mounting plate 21 and the movable plate 22. The two angle sensors 51 are used to detect the azimuth and tilt angle of the antenna body 1 in real time and transmit the detection data to the controller 52. The controller 52 controls the operation of the azimuth adjustment mechanism 3 and the tilt adjustment mechanism 4 according to the preset angle parameters and the detection data of the angle sensor 51.
[0024] Furthermore, the controller 52 is equipped with a storage unit 521, which is used to store historical antenna angle data measured by the angle sensor 51. This historical data can be queried by staff, and in the event of a fault, it can be used to trace the time of the fault for convenient analysis.
[0025] Furthermore, the control device 5 also includes a communication module 54, which connects to the cloud server 7. The communication module 54 uploads the historical antenna angle data stored in the storage unit 521 to the cloud server 7 at preset time intervals.
[0026] Furthermore, the cloud server 7 is equipped with an authentication module 71, a data backup module 72, an automatic adjustment threshold setting module 73, and an active adjustment module 74. Staff can log in to the cloud server 7 via a mobile app. The authentication module 71 verifies the staff's identity, confirming whether the logged-in user has the authority to browse information, modify settings, actively adjust antenna angles, and upload user feedback. The data backup module 72 backs up and stores the antenna angle data uploaded by the communication module 54. The automatic adjustment threshold setting module 73 allows staff to set automatic adjustment thresholds for the azimuth and tilt angles. When the error between the measured antenna azimuth or tilt angle and the angle value set by the active adjustment module 74 exceeds the automatic adjustment threshold set by the staff, the controller 52 automatically adjusts the antenna angle. The active adjustment module 74 allows staff to actively adjust the antenna angle. This enables remote adjustment without the need for on-site personnel. The system also includes a user feedback module for uploading user feedback. For antennas in areas with abnormal communication quality reported by users, historical antenna angle data can be checked to determine if a shift has caused the malfunction.
[0027] Furthermore, the controller 52 is equipped with an automatic detection interval adjustment unit 522, which adjusts the data acquisition interval of the angle sensor 51 according to the automatic adjustment threshold sent by the cloud server 7, thereby reducing energy consumption.
[0028] Example 2: Figure 4-6 As shown, since the angles of multiple antenna bodies 1 need to be controlled separately, each azimuth adjustment mechanism 3 in Embodiment 1 is equipped with an azimuth adjustment motor 31, which is not only costly but also difficult to maintain. Compared with the solution in Embodiment 1, Embodiment 2 uses a single azimuth adjustment motor 31 to drive multiple azimuth adjustment mechanisms 3.
[0029] The mounting platform 62 has a turntable 34 at its center, and a lifting platform 35 is provided above the turntable 34. The azimuth adjustment motor 31 is mounted on the lifting platform 35, and a steering gear 36 is mounted on the shaft of the azimuth adjustment motor 31. A cylinder 371 is mounted on the mounting platform 62, and a gear ring 37 is fixedly provided on the top of the cylinder 371. The gear ring 37 is located outside the turntable 34 and is concentric with the turntable 34. When the lifting platform 35 is lowered, the steering gear 36 meshes with the gear ring 37. The steering gear 36 is a bevel gear, and the gear ring 37 has bevel teeth that mesh with the steering gear 36. A first electromagnetic push rod 38 is fixed to the end of the shaft of the azimuth adjustment motor 31, and a magnetic suction plate 381 is provided at the end of the push rod of the first electromagnetic push rod 38. The first drive gear 32 is mounted on the output shaft of the first gear reducer 8. The first drive gear 32 meshes with the fixed gear 33. A metal plate 81 is mounted on the input shaft of the first gear reducer 8. When the lifting platform 35 is raised, the magnetic suction plate 381 at the end of the first electromagnetic push rod 38 is aligned with the height of the metal plate 81. When the push rod of the first electromagnetic push rod 38 is pushed out, the magnetic suction plate 381 is attracted to the metal plate 81. The azimuth adjustment motor 31 rotates, driving the first electromagnetic push rod 38 to rotate, which in turn drives the first drive gear 32 to rotate through the first gear reducer 8.
[0030] A detection hole 811 is provided at the center of the metal plate 81. A detection frame 341 is also provided above the turntable 34. The detection frame 341 is U-shaped and a laser rangefinder 342 is provided on the top of the detection frame 341. When the lifting platform 35 is lowered and the steering gear 36 meshes with the gear ring 37, the laser rangefinder 342 is aligned with the height of the detection hole 811. When the azimuth adjustment motor 31 drives the turntable 34 and itself to rotate, the laser rangefinder 342 is aligned with the detection hole 811, the azimuth adjustment motor 31 stops rotating, the lifting platform 35 is raised, the first electromagnetic push rod 38 is pushed out, and the magnetic suction plate 381 attracts the metal plate 81. At this time, the azimuth adjustment motor 31 drives the first electromagnetic push rod 38 and the magnetic suction plate 381 to rotate together. The metal plate 81 drives the first drive gear 32 to rotate through the first gear reducer 8. Since the first gear reducer 8 is used, it can be driven with a small torque.
[0031] Furthermore, the magnetic plate 381 is provided with several mounting holes, and a positioning post 383 is installed in the mounting holes by a spring. The metal plate 81 is provided with several positioning holes 812 that are the same shape and position as the positioning post 383. When the first electromagnetic push rod 38 is pushed out, the magnetic plate 381 is brought into contact with the metal plate 81. The azimuth adjustment motor 31 drives the first electromagnetic push rod 38 and the magnetic plate 381 to rotate together. When the positioning post 383 is aligned with the positioning hole 812, the spring pops the positioning post 383 out, and the positioning post 383 is inserted into the positioning hole 812 to complete the positioning. This makes the connection between the magnetic plate 381 and the metal plate 81 tighter, locks the relative rotation, and prevents slippage.
[0032] Furthermore, the detection hole 811 is a two-stage stepped hole. The larger primary hole is used for coarse positioning, and the smaller secondary hole is used for precise positioning. When the laser rangefinder 342 detects the primary hole, the azimuth adjustment motor 31 drives the turntable 34 to rotate back and forth at a low speed within the angle range of the detected primary hole. The low speed range means that the rotation speed does not exceed one revolution per minute. The alignment operation is completed only when the laser rangefinder 342 stably detects the secondary hole, and only then can the lifting platform 35 be raised.
[0033] Furthermore, the mounting platform 62 is provided with a circular track 621 around its center. A slider 622, which can slide along the circular track 621, is provided on the circular track 621. A bracket 624 is mounted above the slider 622 via a second electromagnetic push rod 623. The bracket 624 is Y-shaped, and each of its two forks has a pulley 625 at its top. The bracket 624 is connected to the lifting platform 35 via connecting rods 626. There are two connecting rods 626. When the lifting platform 35 rotates with the turntable 34, it synchronously drives the bracket 624 to move via the connecting rods 626. 4 is located below the first electromagnetic push rod 38, which is placed on two pulleys 625. The lifting platform 35 is driven to rise and fall by several third electromagnetic push rods 351. When the third electromagnetic push rods 351 push the lifting platform 35 to rise, the second electromagnetic push rods 623 simultaneously push the bracket 624 to rise to the same height, so that the bracket 624 keeps supporting the first electromagnetic push rod 38 and prevents the first electromagnetic push rod 38 from falling due to gravity, which would affect docking and transmission. When the second electromagnetic push rod 623 rotates, the two pulleys 625 reduce friction.
[0034] Furthermore, the first electromagnetic push rod 38 is provided with two conductive metal rings 382 on its outer side. The two conductive metal rings 382 are respectively connected to the positive and negative poles of the first electromagnetic push rod 38. The bracket 624 is provided with two power supply brushes 627 on its top. When the first electromagnetic push rod 38 rotates under the drive of the azimuth adjustment motor 31, the two power supply brushes 627 contact the two conductive metal rings 382 respectively. The power supply brushes 627 are connected to the base station power supply.
[0035] Furthermore, the azimuth adjustment motor 31 drives the turntable 34 to rotate within the range of [-180°, +180°] to avoid tangling the power supply wire.
[0036] Furthermore, the laser rangefinder 342, the first electromagnetic push rod 38, the second electromagnetic push rod 623, and the third electromagnetic push rod 351 are all electrically connected to the controller 52.
[0037] The beneficial effects of the angle-adjustable base station antenna of the present invention are as follows: 1. By setting an angle sensor, the azimuth and tilt angle deviations of the antenna can be monitored in real time. When a deviation is detected and the angle needs to be corrected, the azimuth and tilt angles of the antenna body are corrected by the azimuth adjustment mechanism and the tilt adjustment mechanism, effectively maintaining the signal coverage and strength, and solving the angle deviation problem caused by natural factors and environmental changes. 2. The azimuth adjustment mechanism's azimuth adjustment motor drives the first drive gear through a first gear reducer. The first drive gear meshes with a fixed gear fixed on one side of the bearing seat. The reduction effect of the gear reducer can convert the high-speed rotation of the motor into a low-speed, high-torque output. Combined with the precise meshing between the gears, it realizes the micro-angle adjustment of the mounting plate around the mounting shaft, thereby realizing the azimuth adjustment of the antenna body. The tilt adjustment mechanism drives the second drive gear to rotate through a second gear reducer via a tilt adjustment motor. The rotation of the second drive gear meshes with the arc-shaped rack on the arc plate. When the second drive gear rotates, it can drive the arc plate to move. The arc plate pulls the movable plate to rotate around the hinge, thereby realizing the tilt angle adjustment of the antenna body. 3. The control device connects to the cloud server via a communication module. Staff can remotely and actively view or adjust the antenna angle by logging into the cloud server via mobile phone or computer, without having to climb to a high place, thus reducing operational safety hazards; 4. The controller's storage unit and cloud server data backup module can record historical antenna angle data, facilitating traceability and analysis in case of faults; 5. A limiting roller is provided to abut one side of the arc-shaped slot to prevent the second drive gear from disengaging from the arc-shaped rack, ensuring the stable and reliable operation of the tilt angle adjustment mechanism; 6. By meshing the steering gear on the shaft of the azimuth adjustment motor with the gear ring fixedly mounted on the mounting platform, the azimuth adjustment motor can drive itself and the turntable to rotate when it starts, changing the orientation of the azimuth adjustment motor shaft. The orientation is adjusted to align with the antenna body that needs to be adjusted. Only one motor can be used to adjust the azimuth of multiple antenna bodies on the antenna mounting base. 7. By setting up a lifting platform, when the azimuth adjustment motor is raised, the meshing of the steering gear and the gear ring can be separated, realizing the function switching of the azimuth adjustment motor, and aligning the magnetic suction plate at the end of the first electromagnetic push rod with the metal plate installed on the shaft of the first gear reducer. 8. By setting a first electromagnetic push rod, the magnetic plate can be pushed towards the metal plate, connecting the magnetic plate and the metal plate. When the azimuth adjustment motor starts, the azimuth adjustment motor drives the first electromagnetic push rod to rotate.
