When the device is in use, the lifting control rod 7 pushes the transceiver module 4 and the top cover 3 to lift, and the position of the protective cover 5 of the transceiver module 4 is exposed for normal signal transmission and reception. During non-use, the transceiver module 4 retracts into the radome 1 and the multi-functional connecting ring 2 for safety protection. The lifting control rod 7 can be supported and erected by a tripod during use;

[0033] For the rotational movement control of the transceiver module 4, a direct-drive rotating support 6 is realized by using a DC brushless torque motor, achieving precise angle control of the transceiver module 4 and avoiding the gear transmission clearance error generated during long-term use. The direct-drive module also includes an encoder, a control driver, a lithium battery pack, and a slip ring. The encoder is a high-precision 19-bit absolute encoder, enabling the position resolution of the control system to reach 2.5″ and the position accuracy to reach 36″.

[0034] When setting the linkage cleaning component to automatically clean the protective cover 5, it can provide flexible support for the transceiver module 4 when the transceiver module 4 retracts into the radome 1. The linkage cleaning component includes a linkage tray 10 and an elastic support cylinder 15. The linkage tray 10 is arranged at the lower end of the multi-functional connecting ring 2 inserted into the radome 1. The elastic support cylinder 15 is arranged on the inner peripheral side of the multi-functional connecting ring 2, and the elastic support cylinder 15 is in contact with the protective cover 5 of the transceiver module 4.

When the multi-functional connecting ring 2 rotates together with the linkage tray 10, the spiral cleaning strips 16 of the elastic support cylinder 15 scrape the surface dirt of the protective cover 5. At the same time, the elastic cleaning structure of the spiral cleaning strips 16 can provide buffer protection for the transceiver module 4 during the transportation and movement process when it is received into the radome 1.

[0036] Embodiment 2: On the basis of Embodiment 1, a rotating lubrication assembly is provided to perform rotating lubrication maintenance on the rotatable and movable multi-functional connecting ring 2. The rotating lubrication assembly is arranged inside the multi-functional connecting ring 2. The rotating lubrication assembly includes a synchronous ring 18 and a plurality of piston rods 21. On one side of the multi-functional connecting ring 2 inserted into the radome housing 1, a bearing groove 13 is opened. A plurality of self-rotating bearings 14 are inserted into the bearing groove 13. An annular oil groove 23 is opened at the upper end of the multi-functional connecting ring 2 close to the bearing groove 13. A first annular groove 17 is horizontally opened above the annular oil groove 23 inside the multi-functional connecting ring 2. The synchronous ring 18 is horizontally placed in the first annular groove 17. A plurality of downward pressing push rods 19 are vertically and symmetrically arranged at the upper end of the synchronous ring 18. The upper ends of the plurality of downward pressing push rods 19 respectively pass through and are inserted into the upper end of the multi-functional connecting ring 2 in a movable manner. The downward pressing push rod 19 passes through the upper end of the multi-functional connecting ring 2 and contacts the lower end of the top cover 3. A plurality of piston grooves 20 are symmetrically opened at the lower end of the multi-functional connecting ring 2 inside the synchronous ring 18. A plurality of piston rods 21 are vertically and symmetrically arranged at the lower end of the synchronous ring 18. The pistons of the plurality of piston rods 21 are respectively inserted into the plurality of piston grooves 20 in a movable manner. Return springs 22 are sleeved on the rods of the piston rods 21 located inside the synchronous ring 18. When the top cover 3 approaches the multi-functional connecting ring 2, the top cover 3 pushes the plurality of downward pressing push rods 19 to move towards the synchronous ring 18. At this time, the synchronous ring 18 compresses the return springs 22, and at the same time, the pistons of the piston rods 21 move downward in the piston grooves 20;

[0037] A second annular groove 24 is horizontally formed at the lower end of the piston groove 20 inside the multi-functional connecting ring 2. A collection groove is formed in communication between the lower ends of a plurality of piston grooves 20 and the second annular groove 24 respectively. A transfer air groove 25 is formed in communication between the upper end side of the second annular groove 24 and the annular oil groove 23. A first one-way valve 26 is inserted on the side of the transfer air groove 25 close to the second annular groove 24. A third annular groove 27 is formed at the lower end of the annular oil groove 23 inside the multi-functional connecting ring 2. A valve groove is formed in communication between the third annular groove 27 and the annular oil groove 23. A second one-way valve 29 is inserted in the valve groove. A plurality of oil dripping holes 28 are formed between the third annular groove 27 and the bearing groove 13. When the piston of the piston rod 21 descends in the piston groove 20, the air below in the piston groove 20 is pushed into the second annular groove 24 through the collection groove. When the air in a plurality of piston grooves 20 is pushed into the second annular groove 24, the air pressure in the second annular groove 24 increases. The air in the second annular groove 24 pushes the first one-way valve 26 and enters the annular oil groove 23 through the transfer air groove 25. The airflow entering the annular oil groove 23 pushes the lubricating oil in the annular oil groove 23 to push the second one-way valve 29 into the third annular groove 27, and then drips onto the rotating bearing 14 in the bearing groove 13 under the action of a plurality of oil dripping holes 28, so as to continuously lubricate the rotating bearing 14. Furthermore, for each lifting movement of the transceiver module 4, a small amount of lubricating oil can be pushed into the bearing groove 13 for continuous self-lubrication maintenance, improving the smoothness and accuracy of the rotation of the rotating support 6 for controlling the transceiver module 4 and the multi-functional connecting ring 2.

[0038] In this embodiment:

[0039] Embodiment 3: On the basis of Embodiment 2, a sealing airbag ring 30 is embedded at the upper end of the multi-functional connecting ring 2. A plurality of compensation airbags 31 are horizontally and symmetrically arranged at the lower end of the synchronous ring 18 inside the first annular groove 17. A plurality of reset springs 22 are respectively sleeved on a plurality of compensation airbags 31, and an air pipe 32 is inserted in communication between each of the plurality of reset springs 22 and the sealing airbag ring 30. When the top cover 3 contacts the multi-functional connecting ring 2, it is sealed and fitted through the sealing airbag ring 30. When the top cover 3 presses down the push rod 19, the synchronous ring 18 also presses a plurality of compensation airbags 31, causing the sealing airbag ring 30 to expand and change, further improving the effect of pressing and sealing and enhancing the safety for outdoor use.
