Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1-Fig. 6, the entire antenna system mainly is made of antenna reflector 1, antenna rib development mechanism 7, feed and supporting construction 2, antenna arm 8, antenna arm development mechanism 7, antenna support 4 and antenna rotating platform 3.
Antenna reflector is the key component of entire antenna, constituted by many rigidity antenna ribs and flexible reflective material face, because antenna is in light weight, need to draw in repeatedly, and possess the ability of under various environment, working, therefore require very high to the structural design form of rigid backbone and reflection coefficient, the functional reliability of mechanical property and reflecting surface material.Leave the wire netting sewing holes at the antenna rib, reflector is selected the nickel plating stainless steel wire for use, and reflection coefficient 〉=97% allows folding number of times 〉=1000 time.
The antenna development mechanism is mainly formed driving mechanism by motor, harmonic speed reducer, formations such as base, leading screw, feed screw nut, mobile seat, crank connecting link, helical pitch bar, mechanism's integral body needs the function launched under high-reliability and the high and low temperature environment, the motor-driven leading screw rotates during work, feed screw nut is by the displacement disc drivening rod, and connecting rod drive antenna launches and draws in.
It is the main force support structure spare of antenna work that antenna launches arm, needs the intensity height, good rigidity, and weight requires light, therefore launches the square tube design that arm employing cross section is rectangle, and section is in light weight, the moment of inertia is big, good rigidity, and less moment of inertia and higher rigidity are arranged.Launching arm just is responsible for antenna is opened and collected, and do not participate in Satellite Tracking, this driving has auto-lock function, because laying respectively at, XY turntable and umbrella antenna launch above the arm, therefore the stability of launching arm when antenna begins to follow the tracks of will directly have influence on tracking accuracy, carried out special locking design here: be exactly to add electromagnetic brake at the expansion arm, this brake can will launch the position locking firmly of shoulder joint after energising, it is stablized does not rock, and simple to operate, but remote control.
The utility model employing is finished the Position Control of reception antenna accurate (the tracking accuracy height) of satellite (containing low orbit satellite) signal is followed the tracks of and locking, be in rounding state at ordinary times, enter the appointed place during work, at first antenna expansion arm carries out first order expansion, duration of run 10 minutes, and the locking aft antenna carries out the second level to launch, duration of run 15 minutes, carry out antenna self the 3rd utmost point after the locking and launch, duration of run 5 minutes is followed star work by the XY turntable then.
The fast reaction umbrella antenna can be used as rapid consersion unit, enters the work of predetermined work point rapid deployment at any time, imports required satellite index parameter, can finish antenna at short notice and launch the automatically track target satellite.
Its major advantage is that this equipment of fast reaction umbrella antenna mainly possesses characteristics such as motor-driven transportation, rapid deployment, gathering, Satellite Tracking, have height and take in ratio, high-gain, in light weight, draw in, installation volume is little, convenient transportation, easy to operate, be swift in response, and have the ability of key expansion, automatically track target satellite.
Antenna form is umbrella antenna, and it is 4.2m that antenna launches bore, and the diameter after drawing in is less than 1m, and the antenna gross weight is about 65Kg, can draw transportation in transportation in.Antenna design after the gathering has special-purpose integrated packing case, and height and width all satisfy the road transport requirement, also can be used as mobile unit as fast reaction equipment.
