Abstract
The utility model discloses an interchange type parabolic antenna, which comprises a parabolic antenna, wherein the parabolic antenna is formed by splicing a group of interchange type fan-shaped parabolic assemblies (1); and a gap ranging from 1 to 2mm is formed between the adjacent interchange type fan-shaped parabolic assemblies (1). The interchange type parabolic antenna is formed by splicing multi-piece interchange type fan-shaped parabolic assemblies which are convenient to process, is beneficial to professional chemical plants to carry out the standardized production, can strictly control the processing size, improves the precision of the single-piece interchange type fan-shaped parabolic assembly, is good in interchangeability, and can replace the single-piece interchange type fan-shaped parabolic assembly when a problem of the parabolic antenna occurs without affecting the precision requirement of the entire parabolic antenna. Since the interchange type parabolic antenna adopts the multi-piece splicing manner, the gap between the adjacent interchange type fan-shaped parabolic assemblies can be adjusted by selecting the adjusting gaskets of different thicknesses in splicing, so as to ensure the assembly precision.

Summary of the invention
the purpose of this utility model is, a kind of interchangeable parabolic antenna is provided.Difficulty of processing be can reduce to guarantee machining accuracy, assembling and regular maintenance are convenient to simultaneously.
the technical solution of the utility model:
an interchangeable parabolic antenna, comprises parabolic antenna; Parabolic antenna is spliced by one group of fan-shaped parabola assembly of interchangeable; Between the fan-shaped parabola assembly of adjacent interchangeable, be provided with 1～2mm gap.
in aforementioned interchangeable parabolic antenna, the fan-shaped parabola assembly of described interchangeable comprises fan-shaped parabolic panel, and fan-shaped parabolic panel bottom is provided with fan-shaped framework, and fan-shaped framework is angle steel weldment, and the angle steel of fan-shaped framework both sides is provided with connecting hole; The fan-shaped parabola assembly of adjacent interchangeable connects through connecting hole through bolt.
in aforementioned interchangeable parabolic antenna, between the fan-shaped parabola assembly of described adjacent interchangeable, be provided with adjustment packing ring, the thickness of adjusting packing ring is 1～2mm.
in aforementioned interchangeable parabolic antenna, the reflecting surface of described parabolic antenna is provided with one group of pole, the fan-shaped framework of pole one end and gap, the fan-shaped parabola assembly place of adjacent interchangeable bottom is connected, the pole other end be positioned at parabolic antenna and reflect the subreflector that Jiao orders and be connected.
in aforementioned interchangeable parabolic antenna, described parabolic antenna center is provided with feed network, and feed network is column.
in aforementioned interchangeable parabolic antenna, described parabolic antenna is connected with bearing through radiation beam, centerbody and angle regulator.
compared with prior art, parabolic antenna of the present utility model is spliced by the fan-shaped parabola assembly of multi-disc interchangeable, the fan-shaped parabola assembly of interchangeable is easy to process, be conducive to specialized factory and carry out standardized production, can strict controlled working size, improve the precision of the fan-shaped parabola assembly of interchange formula, interchangeability is good, if parabolic antenna goes wrong, can change by monolithic, do not affect the required precision of whole parabolic antenna.Owing to having adopted the assembled mode of multi-disc, during tipping, can, by selecting the adjusting pad of different-thickness, regulate the gap between the fan-shaped parabola assembly of adjacent interchangeable, to guarantee assembly precision.
