Problems solved by technology

Due to the limitation of this installation method, the feed source bracket must be completely removed before each maintenance or replacement of the feed source
At the same time, because the feed source bracket of a large parabolic antenna often has a large size and high weight, it greatly increases the difficulty of maintenance and installation, increases the construction time, and increases the construction cost.
At the same time, since the feed source is fixed mechanically and does not have the ability to move, if you want to eliminate the position error caused during the installation process, the construction personnel need to repeatedly climb and debug, which increases the difficulty of construction, increases the construction risk, and prolongs the construction time.

Abstract

The embodiment of the invention discloses a focusing system for an antenna feed source. The focusing system comprises a waveguide, wherein the front end of the waveguide is provided with a feed source, and the rear end of the waveguide is provided with a lead screw nut; a lead screw sleeved with the lead screw nut; a driving motor, wherein the output shaft of the driving motor is coupled to the lead screw for driving the lead screw; and a linear guide rail provided with a guide rail slider and connected to the waveguide. The focusing system is provided with the driving motor and the lead screw, and the lead screw nut is fixed to the rear end of the waveguide. The driving motor moves the lead screw in order that the lead screw nut moves the waveguide horizontally when moving along the horizontal direction, thereby moving the feeding source in the horizontal direction and electrically focusing the feed source. As a result, a worker can adjust the position of the feed source by controlling the drive motor on the ground.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a focusing system for antenna feed sources. Background technique [0002] At present, most of the feedforward feed structures of large parabolic antennas are directly fixed on the feed bracket through mechanical buckles. Due to the limitation of this installation method, the feed source bracket must be completely removed before each maintenance or replacement of the feed source. At the same time, since the feed source support of a large parabolic antenna often has a large size and high weight, it greatly increases the difficulty of maintenance and installation, increases the construction time, and increases the construction cost. At the same time, since the feed source is fixed mechanically and does not have the ability to move, if you want to eliminate the position error caused during the installation process, construction personnel need to repeatedly climb and debug, which in...
