Description
Technical field：
Technical field of communication equipment is the utility model is related to, more particularly to a kind of microwave antenna.
Background technology：
The agent structure of the microwave antennas such as satellite signal receiver is generally made up of parabola antenna and feed, wherein parabolic
Surface antenna reflecting focal satellite-signal ripple, transmit from the feed reception being placed at parabolic focus and to signal handling equipment.
Because the outdoor arrangement of microwave antenna is often selected at the spaciousness such as roof, and a large amount of metal materials are used, because
Situation about being struck by lightning occurs in this, in the case where being provided with lightning rod, also easily because the feed location of high value is high, participates in
Point discharge and cause to damage.
The content of the invention：
In consideration of it, being necessary to design a kind of microwave antenna that can prevent feed in thunder and lightning environmental damage, solve above-mentioned
Problem.
Anti-lightning strike microwave antenna, including：Feed, universal bearing, main parabolic reflector, secondary parabolic reflector, secondary reflection
Face support, ball watt, ball axle, spray point and ground wire；Wherein, universal bearing points to adjustable, and main parabolic reflector central openings are simultaneously
It is sleeved on universal bearing, main parabolic reflector is rotatable with respect to universal bearing, and main parabolic reflector upper limb is provided with secondary reflection
Face support, subreflector support extends to main parabolic reflector focal point, and secondary parabolic reflector, feed are installed below focus
Installed in universal bearing top；Ball watt is arranged on subreflector mid-stent, and ball axle is provided with spray point, and spray point passes through ball
Axle is rotatably connected with ball watt；Spray point, ball axle, ball watt, subreflector support, main parabolic reflector use conductor and connection
Conducting, main parabolic reflector lower surface is connected with ground wire, insulated between main parabolic reflector and universal bearing.
After installation, microwave antenna is by the sensing control signal transmit-receive position of universal bearing, and main parabola is around universal bearing
Rotate, adjustment subreflector support to its upper side, spray point is upwardly extended by subreflector support and form equipment peak, shape
Into point discharge, region of discharge is set to avoid feed.Receiving and transmitting signal is after main parabolic reflector and the secondary reflection of secondary parabolic reflector two
Converge at feed, to complete microwave antenna function.
Preferably, ball axle is passed through in the middle part of spray point, bottom is provided with counterweight, spray point is always vertically above referred to, avoids making
With devices such as set screws, prevent from failing.
The utility model is designed by the paraboloid structure of two secondary reflections with the spray point for electrically isolating from feed, avoids feed
Point discharge region, effectively prevent from damaging the situation of feed under thunder and lightning weather or under other high electrostatic environment, add equipment
Service life.
Brief description of the drawings：
Accompanying drawing 1 is the specific embodiment structural representation of anti-lightning strike microwave antenna.
In figure：Feed 1, universal bearing 2, main parabolic reflector 3, secondary parabolic reflector 4, subreflector support 5, ball watt 6,
Ball axle 7, spray point 8, counterweight 9, ground wire 10.
Embodiment：
Anti-lightning strike microwave antenna, including：Feed 1, universal bearing 2, main parabolic reflector 3, secondary parabolic reflector 4, pair
Reflecting surface support 5, ball watt 6, ball axle 7, spray point 8, counterweight 9 and ground wire 10；Wherein, universal bearing 2 points to adjustable, main parabolic
The central openings of reflecting surface 3 are simultaneously sleeved on universal bearing 2, and main parabolic reflector 3 is rotatable with respect to universal bearing 2, and main parabolic is anti-
To penetrate the upper limb of face 3 and subreflector support 5 is installed, subreflector support 5 extends to the main focal point of parabolic reflector 3, and in focus
Secondary parabolic reflector 4 is installed in lower section, and feed 1 is arranged on the top of universal bearing 2；Ball watt 6 is arranged on the middle part of subreflector support 5,
The middle part of spray point 8 passes through ball axle 7, and bottom is provided with counterweight 9, and spray point 8 is rotatably connected by ball axle 7 and ball watt 6；Spray point
8th, ball axle 7, ball watt 6, subreflector support 5, main parabolic reflector 3 are turned on using conductor and connection, under main parabolic reflector 3
Surface is connected with ground wire 10, is insulated between main parabolic reflector 3 and universal bearing 2.
