Abstract
The utility model discloses a polarizing angle adjuster. A feed source (9) is fixedly connected on a diplexer (1), a motor (10) is arranged at one side of the feed source (9), the output end of the motor (10) is fixedly connected with a first gear (12), and a second gear (6) is fixedly connected with the feed source (9) and engages with the first gear (12). When the polarizing angle is required to be adjusted, the motor is driven, then the first gear starts rotating and drives the second gear engaging therewith to rotate at the same time, and because the second gear is fixed on the feed source, the second gear can drive the feed source to rotate to a desired angle according to the system command after the motor rotates, so as to avoid manual operation and save adjusting time, reach accurate adjusted angle.
Description
Technical field
The utility model relates to a kind of polarizing angle adjuster, is the mechanism of the adjustment received signal used of satellite communication field reception antenna, belongs to satellite communication antena and uses the attachment technique field.
Background technology
Because the geographical position difference at satellite signal receiving antenna place, the influence of satellite longitude difference and earth curvature, need there be an angle of inclination (being polarizing angle) on the relative ground of Satellite Receiving Station feed waveguide mouth, could mate with the satellite polarization mode, better received signal, in the prior art, the polarizing angle that satellite receives earth-fixed station adjustment feed waveguide mouth need manually come manually to finish, accuracy mainly relies on range estimation, it is long that this polarizing angle is adjusted the mode required time, accuracy can not get guaranteeing simultaneously, especially in the occasion of satellite emergency mobile communication, can not satisfy the demand of work.
Summary of the invention
The utility model provides a kind of manual operations, time saving and energy saving polarizing angle adjuster accurately of adjusting simultaneously of not needing when adjusting polarizing angle.
The utility model adopts following technical scheme:
A kind of polarizing angle adjuster is fixedly connected with feed on duplexer, be provided with motor in a side of feed, and the output of motor is fixedly connected with first gear, is fixedly connected with second gear on feed, and above-mentioned second gear and first gears engaged.
Side at feed is provided with the electromagnetism electricity loss brake, is provided with spragging gear on the electromagnetism electricity loss brake, and the spragging gear and second gears engaged, and above-mentioned electromagnetism electricity loss brake and spragging gear are formed automatic locking mechanism.
Duplexer is provided with the first rotary spacing switch and the second rotary spacing switch, and the first rotary spacing switch and the second rotary spacing switch) be symmetrically distributed in the both sides of the center line of duplexer, the center line of the first rotary spacing switch and the second rotary spacing switch is orthogonal, be provided with guide vane end stop on second gear, above-mentioned guide vane end stop, the first rotary spacing switch and the second rotary spacing switch are formed rotating and limiting mechanism.
Compared with prior art, the utlity model has following advantage:
1, the utility model has in use been avoided manual operations, can have been saved and adjust the polarizing angle required time, and is time saving and energy saving.When needing to adjust polarizing angle, drive motors, such first gear just begins to rotate, second gear of drive and its engagement rotates simultaneously, owing to second gear is fixed on the feed, so after the motor rotation, will drive feed rotates with it, instruction according to control system makes feed turn to the angle of needs, the artificial operation of avoiding, and the angle of having saved adjustment time and adjustment is accurate.
2, the utility model is by being provided with automatic locking mechanism, just can guarantee the stability of the polarizing angle adjusted.Because after electromagnetism dead electricity controller outage, spragging gear will with second gears engaged, prevented the rotation of feed under the situation that vehicle jolts or other parts are loosening, so just avoided the variation of polarizing angle, strengthened practicality of the present utility model.
