[0069] In actual application, the column-type antenna base of the present invention can drive the turntable assembly 3 to rotate around the column 2 through the azimuth drive mechanism 6, and the antenna drive mechanism 7 can drive the antenna 8 to swing to adjust its pitch angle, thereby realizing two-dimensional high-precision rotation of the antenna base. In actual applications, the column 2 is used to carry other equipment such as optoelectronic equipment, and multiple detection devices that rotate independently can be installed in series through the column, providing an effective solution for the integrated design of microwave radar, optoelectronic equipment, etc., thereby solving the problem that the traditional antenna base cannot realize the structural series connection of multiple rotatable detection devices and the technical problem that the traditional antenna base cannot meet the requirements of carrying microwave antenna arrays and optoelectronic equipment at the same time. The present invention not only allows the antenna to rotate in two dimensions, but also provides an installation platform for optoelectronic equipment, and there is no interference between the two types of equipment.

[0070] The support flange 21 is used to support the bearing 42 and the turntable assembly 3 to ensure that the turntable assembly 3 can rotate freely while preventing it from sliding down along the column 2, and the structure is stable and reliable. The sealed space formed between the two sealing rings 34 can effectively isolate the bearing 42 from the outside world, prevent foreign objects from intruding, ensure that the bearing 42 can operate normally, and have a long service life. In actual applications, the cylindrical portion 35 cooperates with the top cover 22 to isolate the top of the column 2 from the outside world, prevent foreign objects from intruding, and protect the internal structure, ensuring that the antenna base can operate normally.

[0071] The turntable assembly 3 formed by the upper turntable 31, the lower turntable 32 and the truss-type connecting rod 33 has strong rigidity and good stability. The slewing bearing 41 can stably support the operation of the turntable assembly 3 and ensure that the turntable assembly 3 rotates smoothly. The motor 61 drives the gear 62 to rotate, and the gear 62 drives the inner ring of the slewing bearing 41 and the turntable assembly 3 to rotate relative to the outer ring of the slewing bearing 41 through the outer teeth of the outer ring of the slewing bearing 41. The overall structure is simple and the operation is reliable. The sealing cylinder 14 cooperates with the annular member 36 to separate the slewing bearing 41 and the azimuth drive mechanism 6 from the outside world to prevent foreign matter from intruding, protect the internal structure, and ensure that the antenna seat can operate normally. In practical applications, the antenna 8 can be driven to swing up and down by the extension and retraction of the electric push rod, thereby adjusting the pitch angle of the antenna 8. The structure is simple and the operation is reliable.
