Description
Technical field
The present invention relates to parabola antenna technical field, and in particular to a kind of parabola antenna unit machine of rapid deployment
Structure, suitable for various bores, various forms of parabola deployable antennas.
Background technology
Antenna plays huge economic and social benefit as a kind of Wireless Telecom Equipment.By reflecting surface formal classification,
Parabola antenna can be divided into net paraboloid antenna and entity parabola antenna.The research of netted deployable parabola antenna is
It is quite varied, it is mainly used in the fields such as deep space communication, but the relevant design of the deployable parabola antenna of entity is stagnated always.
Application scenario with landing ground emergency communication is more and more extensive, it is desirable to which the installation rate of the deployable parabola antenna of entity gradually carries
It is high.How rapid deployment and the collection of reflecting surface is realized, it has also become the key of such antenna.At present, the deployable throwing of entity is commonly used
Object plane antenna mainly uses manual attaching/detaching panel, and labor intensity is big, and attaching/detaching speed is slow, needs more than 25 minutes.This
Outside, after panel installation, it is still necessary to carry out precision adjustment, significantly limit such antenna answering in emergency communication field
With.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of unit mechanisms of quick deployable parabola antenna, can be achieved
The rapid deployment of parabola antenna, positioning precision is high, without secondary adjustment, especially suitable for quick response in emergency circumstances.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of parabola antenna unit mechanisms of rapid deployment, including antenna reflective face unit 1, described antenna reflective face
A valve in some valves that unit is divided equally along center line for the annular parabola antenna of circular open, it is characterised in that：Also include
Supporting plate 2, connecting plate 6, fan-shaped turntable 4 and fan-shaped turntable support 5；Described fan-shaped turntable is inclined at fan-shaped turntable support
It can be rotated on 5 and by the central axis of fan-shaped turntable；One end of described supporting plate 2 is radially fixed to antenna list
One lateral edges at first back side and, the side of supporting plate 2 other end and one end phase of connecting plate perpendicular with the antenna element back side
Fixed, the other end of connecting plate is fixed on the circumference of fan-shaped turntable upper surface.
Wherein, the end face of fan-shaped turntable 4 and the mouth face of annular parabola antenna are in 30 ° of -45 ° of angles, while the sector turns
The axis of the end face of disk 4 and excessively annular parabola antenna and perpendicular to the mouth face of annular parabola antenna normal plane in 45 °-
75 ° of angles.
Wherein, in the circumferentially arranged support 3 having for supporting antenna element in the antenna element back side, one end of support 3 with
Supporting plate 2 is connected.
Wherein, a side end face of described antenna reflective face unit is provided with chamfering with back side intersection.
It is using beneficial effect caused by above-mentioned technical proposal：
(1) present invention realizes the expansion and collection of parabola antenna by tilting the structure of elevating arc, avoids antenna
Face expansion during interfering, it is simple in construction, it is easy to accomplish, for antenna surface freely deploy and collection provides guarantee.
(2) panel-form that uses of the present invention, interfering between panel is avoided.
(3) present invention realizes the rapid deployment and collection function of parabola antenna, simple in construction, is adjusted without panel precision
The features such as whole, stable and reliable for performance, the labor intensity of the operating personnel of antenna expansion and collection is reduced, has ensured case of emergency
Under, quick collection and the expansion of antenna, improve antenna Emergency use ability.
