Since the second gear ring 435 is sleeved on the rotating seat 433, the moving second gear ring 435 can drive the rotating seat 433 to move, thereby driving the first transmission component 44 or the second transmission component 45 on the corresponding rotating seat 433 to move. The moving first transmission component 44 and the second transmission component 45 can adjust the position and angle of the antenna 3, so that it can avoid the same-frequency interference between the antennas 3 while also enabling it to obtain the maximum coverage range.

In the frame 2, the antenna 3 is prevented from falling during the disassembly process; when it is necessary to drive the first transmission component 44 or the second transmission component 45 to move, the driving motor 431 starts to work, and the moving driving motor 431 can drive the adjusting gear 432 connected thereto to rotate, and then the moving adjusting gear 432 can drive the second gear ring 435 meshing therewith to rotate. Since the second gear ring 435 is sleeved on the rotating seat 433, the moving second gear ring 435 can drive the rotating seat 433 to move, thereby driving the first transmission component 44 or the second transmission component 45 on the corresponding rotating seat 433 to move, and the moving first transmission component 44 and the second transmission component 4 5 can adjust the position and angle of the antenna 3, so that it can avoid the same-frequency interference between the antennas 3 and obtain the maximum coverage range; when the first transmission assembly 44 needs to start moving, the first placement seat can be rotated through the cooperation of the set driving motor 431, the adjustment gear 432 and the second gear ring 435, so that the first placement seat can be in a rotating state, thereby driving the connecting ear 443 to rotate, and then the moving connecting ear 443 can drive the third transmission rod 441 movably connected thereto to move, and then the moving third transmission rod 441 can drive the support rod 483 to move through the set driving member 442, so that the support rod 483 can move along the movable The connection between the seat 482 and the driving rod 481 is rotated, so as to adjust the position of the hinge seat 46, and complete the position adjustment of the antenna 3; when one of the driving components 43 starts to work, the moving driving component 43 can drive the second placement seat to rotate. At this time, since the driven block 4343 is fixedly installed on the second placement seat, when the second placement seat starts to rotate, the moving second placement seat can drive the driven block 4343 to move together. At this time, the moving driven block 4343 can drive the driving rod 481 to rotate, and then the moving driving rod 481 can make the transmission part 48 move, thereby ensuring the transmission of the motion, and completing the adjustment of the angle and position of the antenna 3;By setting the connecting shaft 4341 and the ball bearing 4342, the first placement seat and the second placement seat can be made independent of each other without interfering with each other, so that the driving component 43 can drive the corresponding first placement seat and the second placement seat to rotate, thereby completing the adjustment of the position of the antenna 3, avoiding interference between the two and causing failure of the adjustment work; when the driving rod 481 starts to move, the moving driving rod 481 can drive the movable seat 482 to move, and when the driving rod 481 starts to move, the moving driving rod 481 can drive the movable seat 482 to move, thereby changing the axial direction of the movable seat 482 and the driving rod 481 The angle on the support rod 483 can be raised or lowered to complete the adjustment of the position of the antenna 3; when the driving rod 481 starts to work, the position of the movable seat 482 can be adjusted. Since the first transmission rod 451 in the second transmission assembly 45 is movably connected to the side plate 436 and one end of the second transmission rod 454 is movably connected to the hinged seat 46, when the movable seat 482 moves, a relative displacement occurs between the rotating disk 452 and the movable seat 482. Then, through the cooperation of the first transmission rod 451 and the second transmission rod 454, the angle of the antenna 3 can also be adjusted during the process of adjusting the height of the antenna 3, so that it can ensure that the antenna 3 is in a stable state. 3 can transmit or receive signals while covering a larger range, so that the base station antenna 3 can work normally; when it is necessary to clean the water droplets remaining on the antenna 3, the pop-up motor 52 starts to work, and the moving pop-up motor 52 can make the pop-up rod 54 rotate around the transmission shaft 53. In this process, since there is a predetermined angle between the length direction of the torsion spring 510 and the height direction of the installation frame 51, in the initial stage of the movement of the pop-up rod 54, one end of the pop-up rod 54 equipped with the air nozzle 55 approaches the bottom of the installation frame 51, and then under the cooperation of the torsion spring 510 and the driving motor 431, a relative displacement occurs between the slide plate 58 and the installation frame 51. When the sliding plate 58 and the mounting frame 51 form an active groove for the pop-up rod 54 to move, the pop-up rod 54 moves in the opposite direction and extends out of the mounting frame 51, so that the position of the air nozzle 55 can be adjusted, and then the blowing device 56 starts to work. The moving blowing device 56 can generate airflow, which enters the air duct along the connecting pipe 57 and is ejected from the air nozzle 55, so that the water droplets attached to the antenna 3 can be removed. By using a non-contact water drop removal method, the water drop removal process can avoid affecting the work of the antenna 3. At the same time, the heating part is set to avoid the formation of crushed ice on the antenna 3 when the temperature is low, so as to ensure the normal operation of the antenna 3. ;
