Description
Technical field
The utility model is related to satellite communication fields, are specially a kind of satellite communication antena system structure.
Background technology
The existing satellite communication antena structure type in market is more, and the function of various antenna is also not quite similar.Communication in moving is defended
Star communication system is mounted on mobile vehicle (mainly marine fishing boat), real by geosynchronous satellite during the motion
The system of existing real-time Communication for Power, and to ensure to communicate normally and incessantly in the quick motion process of carrier.
The satellite communication antena structure being currently installed on mobile vehicle is primarily present problems with：
1st, vibration damping problem：In the installation of existing antenna structure, in order to eliminate influence of the installation surface vibration to equipment, all exist
Vibration absorber is installed, the vibration absorber of generally use is flexible connector between equipment and stationary plane.Such vibration absorber
Although the vibration for certain single-degree-of-freedom that can be transferred to effective attenuation mounting surface on antenna, often makes between mounting surface and antenna
Other degree of freedom rigidity and intrinsic frequency reduce, causing the motion control difficulty of antenna movement part increases, influence entirely
Capability of engineering equipment index.
2nd, it is driven problem：Transmission problem mainly tension structure problem and second belt deceleration transmission including primary transmission
Problem is pre-tightened respectively：
In the application of existing primary transmission synchronous belt, toothed belt transmission must have appropriate tensile force (initial tension), with
Just expected transmission effect is reached.Tensile force is too small to make synchronous belt that slippage phenomenon occur due to engagement is bad in operation,
The moment of tooth is jumped, band may be made to be broken or damage or come off with tooth due to pulling force is excessive；Tensile force is too small also to make synchronous belt
Transferring the precision of movement reduces, and easily skids, the serious wear of band, the vibrating noise of band becomes larger.And tensile force is excessive, can make band
Stress is excessive, service life reduction, drive noise increase, and the load increase on axis and bearing, aggravating the fever of bearing makes bearing life
It reduces.Therefore it is the essential condition for ensureing toothed belt transmission normal work that control drive coordination band, which keeps suitable tensile force,.Simultaneously
Also need the cornerite of consideration synchronous belt.Cornerite is smaller, and contact arc length is shorter, and load tooth is fewer, and the power that tooth is born is bigger, influences whether
The torque of transmission and be easy to causeing the damage of tooth makes belt wheel skid.Common solution is to use tensioning wheel or pinch roller,
Tensioning wheel is typically located at the inside of receding side of belt；Pinch roller is usually placed in the outside of synchronous belt slack list.Domestic elasticity at present
Self-regulation structure is mostly reached using elastomeric element can automatic rebounding control belt, the tensioning of the chain.Elastomeric element uses bullet more
Spring structure, such as metal spring stretcher.It is typically placed in behind driving device, at tension minimum, since tension is by spring
Coefficient limits, so applying in general to the little occasion of temperature change, the service life is shorter；After tensioning, it is impossible to bear larger outside
Shock loading, installing and dismounting is inconvenient, and particularly corrosion resistance is poor.
And in the application of existing second belt deceleration transmission, when the centre-to-centre spacing of belt cannot be adjusted, frequently with tensioning
Wheel or pinch roller pre-tighten.Tensioning wheel is typically located at the inside of slack list, so that belt is only by bend in one direction；And pinch roller leads to
The outside of receding side of belt is often arranged in, in order to avoid belt stress bends excessive, a pair of of pinch roller of installation in synchronous belt both sides.Two
Kind of firmly beforehand means can reduce the slip in transmission, ensure accurate gearratio by adjusting the tensile force of belt, transfer compared with
It is high-power.But two kinds of firmly beforehand means are both needed to pre-tighten two-stage belt respectively, it is complicated, work efficiency is low, cost compared with
Height, and because belt is different by tensile force the degree of bending, the service life of belt is caused to reduce.
3rd, rotary stopper problem：, it is necessary to control the scope of rotating mechanism rotation, usually in antenna rotary course
It is realized by the way of electric-mechanic control system.It common are the modes such as touching switch, tongue tube and angular encoder.But it is defended in boat-carrying
In star communication, due to particular/special requirement, it is merely able to carry out /V using purely mechanic mode.And purely mechanic mode /V at present mainly should
For the control in the range of 360 degree, limited block or limited post such as are installed to realize /V in the position of control, but work as rotating range
During more than 360 degree, the mode of limited block or limited post just fails.
4th, cable winds problem：While 360 ° of continuous rotary motions of antenna equipment, the mechanical structure on rotary body is also
Need polynary movement.To ensure that the electric appliance on rotary body can also free movement while rotary motion, it is necessary to use rotation
Communication apparatus occurs to sprain and break to avoid conducting wire in rotary course.Slip ring is most common rotational communication device.But it deposits
In following deficiency：(1) friction has resistance value between contact so that the service life of slip ring is not grown and the signal strength in transmission signal
There is attenuation.(2) in slip ring the contact of current collector be it is exposed can not shield, therefore slip ring is when transmitting multichannel data signal, letter
It will be interfered with each other between number.(3) two contacts in slip ring between current collector need to use expensive high performance material to make, and slip ring
Complicated requirement on machining accuracy it is high, the manufacture cost for thereby resulting in slip ring is very high.(4) it is not suitable for adverse circumstances.
5th, fixed deformation problem：Satellite communications system antenna aperture is all smaller.At present for small size antenna, day
Line mouth face (satellite pot) is usually directly anchored to using the preformed hole of pot radial equipartition on posterior bracket, and satellite pot is mating
The feed and polarizing unit of installation are also to be directly installed in pot, and the weight of feed and polarizing unit is all applied to satellite pot
On, when external vibration environment is more violent, easily pot is caused to deform, and then influence the degradation of signal.
