Description
Technical field
This utility model relates to satellite communication field, is specifically related to a kind of novel boat-carrying three-axis satellite antenna for satellite communication in motion system
System.
Background technology
At present satellite antenna all uses orientation, pitching, polarization three through-drive, and often stormy waves is very big or searches championship and puts on ground
During ball equator, three through-drive all cannot meet tracer request, and the feed of satellite antenna is mostly with the shape of support at present
Formula is arranged on focal position facing to antenna surface, and tuner is directly installed on feed or uses feed and tuner one
Version is arranged on the front end of antenna surface, the most usually said feed forward type antenna.And in mobile satellite antenna, due to carrier
Movement, need feed polarisation angles is made adjustment in real time, this is accomplished by feed in addition certain drive mechanism.And it is front
Antenna aperture is the most just caused by these structures of end to be blocked, and especially to small aperture antenna, greatly reduces the efficiency of antenna.Separately
Outward, control cable and the video line of antenna are mostly connected to indoor with the form of dish line by conventional antenna, and this results in antenna
Azimuth suffers restraints, and need to install stopping means additional；General maximum azimuth also only 720 ° and time carrier moves or turns, system
Go to extreme position during tracking unavoidably and cause dropout.
Utility model content
This utility model provide a kind of simple for structure firmly, weight is light, low in energy consumption, system response time fast, transmission
The boat-carrying three-axis satellite antenna for satellite communication in motion system that control accuracy is high, reliable.
In order to achieve the above object, this utility model has a following technical scheme:
A kind of novel boat-carrying three-axis satellite antenna for satellite communication in motion system of this utility model, by Antenna baseplate, orientation assembly, bows
Facing upward assembly, antenna surface and feed polarization component composition, orientation assembly is arranged on Antenna baseplate, and feed polarization component is arranged on sky
On the backboard in line face, also include that roll assembly, described roll assembly bottom are fixed with orientation assembly by antenna main support, top
Realize being rotationally connected by bearing and tilting component.
Wherein, described orientation assembly, roll assembly, tilting component and feed polarization component all use two grades of V belt translation modes
Realize transmission.
Wherein, described roll assembly is made up of with antenna crossbeam the big belt wheel of roll and passes through that stud is firm to be connected.
Wherein, described feed polarization component is made up of the drive mechanism that polarizes, power amplifier, feed and duplexer structure.
Wherein, described orientation assembly includes orient core axle, orientation swinging mounting group, azimuth-drive motor, the big belt wheel in orientation, side
Position small pulley, orientation transition pulley, orientation belt shaft, the big belt wheel of orient core axle and orientation is coaxially mounted to the middle part of base,
Orientation swinging mounting group is rotationally connected by the big belt wheel in bearing and orientation, and azimuth-drive motor is fixedly mounted on orientation swinging mounting group
On, the axle of azimuth-drive motor and orientation small pulley Joint, orientation belt shaft is rotatably coupled to orientation rotation by bearing
On frame, the bonded one end at orientation belt shaft of transition pulley.
Owing to taking above technical scheme, the utility model has the advantage of:
1, satellite antenna uses ring-focus paraboloid antenna, have employed rear feed structure and reduces tuner, power amplifier, polarization transmission
Antenna aperture is blocked by mechanism, improves the service efficiency of antenna surface and reduces antenna sidelobe；
2, the duplexer of satellite antenna directly receives signal from Feed Horn mouth, and power amplifier and feed are the most directly connected on duplexer
After, greatly reducing signal decay in transmitting procedure；
3, orientation, pitching, roll, polarization transmission all use the simple motor+toothed belt transmission+feedback system of control
Structure, both ensure that the lightest of system structure, in turn ensure that stability and the transmission accuracy of drive system；
4, each parts of this utility model mostly use aluminum profile extrusion, it is ensured that system structure is light, and rotary inertia is little, intensity
Get well and batch production low cost.
5, each transmission component of this utility model all uses the additional feedback system of motor for driving element, makes transmission become
Economical and accurate, increase roll assembly simultaneously, meet orientation, pitching, roll, polarization muti-azimuth track, drive mechanism is equal
Use the toothed belt transmission of high-quality, it is to avoid because long-time load friction is lost the driving error brought, this utility model structure
Succinct and firmly, weight is light, low in energy consumption, system response time is fast, drive control precision is high, reliable, can be widely used for
Various vehicles, boats and ships, it is achieved the satellite communication function in carrier moving process.
