Abstract
The invention discloses a connecting method and a connecting structure for improving the main reflector accuracy of an antenna. When a main reflection panel of the antenna is connected to a central body, an additional adjusting assembly is fixed at the top surface of the central body at first, then the small end of the main reflection panel is connected to the additional adjusting assembly, and the main reflection panel is enabled not to be contacted with the central body directly but to be adjustably connected with the central body through the additional adjusting assembly. The main reflector accuracy of the antenna can be improved by adopting the method disclosed by the invention. The connecting method removes fixing bolts in the prior art, and adopts the additional adjusting assembly to connect the small end of the main reflection panel and the top part of the central body, thereby overcoming a technical problem in the prior art that a range of about 1-1.2 meter of the small end of the main reflection panel cannot be adjusted. The improved structure enables the main reflection panel to be completely supported through the adjusting assembly, and enables the main reflection panel to fully stay at a suspended state, thereby not causing the main reflection panel to be deformed in the adjusting process, and being capable of prolonging the service life of the main reflection panel.
Description
Technical field
the present invention relates to a kind of method of attachment and structure that improves antenna main reflector precision, belong to the packaging technology field of large-scale antenna.
Background technology
existing antenna is to form by being distributed on centerbody one group of principal reflection panel around.Principal reflection panel is sector structure, and the little head end of principal reflection panel is bolted on centerbody, and the back side of principal reflection panel is connected with radiation top surface of the beam by one group of adjusting device, and the center-side of radiation beam is connected with centerbody side.Can regulate principal reflection panel angle by adjusting device, thereby reach design electrical performance indexes, realize antenna function requirement.
but because the microcephaly of the principal reflection panel of existing syndeton is rigidly connected by bolt and centerbody, so be difficult to principal reflection panel to be adjusted to optimum precision requirement in the scope that approaches 1～1.2 meter of tie point, be to perplex for a long time designer's technological difficulties.
Summary of the invention
the object of the invention is to, a kind of method of attachment and structure that improves antenna main reflector precision is provided, change being rigidly connected between principal reflection panel microcephaly end and centerbody into floating connection mode, to overcome the deficiencies in the prior art.
technical scheme of the present invention:
a kind of method of attachment that improves antenna main reflector precision of the present invention is, in the time that the principal reflection panel of antenna is connected with centerbody, first on the end face of centerbody, fix newly-increased adjusting part, then the little head end of principal reflection panel is connected on newly-increased adjusting part, principal reflection panel is not directly contacted with centerbody, but carry out adjustable connection by newly-increased adjusting part, can improve by this method antenna main reflector precision.
the of the present invention a kind of syndeton that improves antenna main reflector precision building according to said method is, this structure comprises one group of principal reflection panel, one group of the bottom surface adjusting part of principal reflection panel is connected with radiation beam, radiation beam is bolted the side that is fixed on centerbody, and the microcephaly of principal reflection panel holds through newly-increased adjusting part and is connected with the end face of centerbody.
owing to having adopted technique scheme, compared with prior art, the present invention changes being rigidly connected between principal reflection panel microcephaly end and centerbody into floating connection mode in the present invention.Cancel existing set bolt, adopt newly-increased adjusting part by principal reflection panel microcephaly end and centerbody top
connect, while so not only having avoided assembling, easily causethe problem of principal reflection panel distortion, but also
overcome prior artthe technical problem that principal reflection panel microcephaly holds the scope of about 1～1.2 meter to regulate.Because the structure after improving supports principal reflection panel completely by adjusting part, make principal reflection panel in complete suspended state, in adjustment process, can not cause the distortion of principal reflection panel, can extend the useful life of principal reflection panel.
Accompanying drawing explanation
fig. 1 is structure diagram of the present invention;
fig. 2 is the structural representation of prior art.
being labeled as in accompanying drawing: 1-principal reflection panel, 2-adjusting part, 3-radiation beam, 4-centerbody, 5-increases adjusting part newly, 6-bolt.
Embodiment
below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
embodiments of the invention: a kind of method of attachment that improves antenna main reflector precision of the present invention can be directly used in large-scale antenna of the prior art is improved to enforcement, when enforcement, in the time that the principal reflection panel 1 of existing antenna is connected with existing centerbody 4, first on the end face of centerbody 4, fix newly-increased adjusting part 5, then the little head end of principal reflection panel 1 is connected on newly-increased adjusting part 5, principal reflection panel 1 is not directly contacted with centerbody 4, but carry out adjustable connection by newly-increased adjusting part 5, can improve by this method antenna main reflector precision.
when concrete enforcement, can adopt a kind of syndeton that improves antenna main reflector precision of the present invention to implement, the structural representation of this syndeton as shown in Figure 1, this syndeton comprises one group of principal reflection panel 1, one group of the bottom surface adjusting part 2 of principal reflection panel 1 is connected with radiation beam 3, radiation beam 3 is bolted the side that is fixed on centerbody 4, its principal reflection panel 1, adjusting part 2, radiation beam 3 and centerbody 4 all adopt legacy device of the prior art, then the microcephaly of principal reflection panel 1 is held and be connected with the end face of centerbody 4 through newly-increased adjusting part 5.Its newly-increased adjusting part 5 can directly adopt the adjusting part the same with adjusting part 2 of the prior art.
fig. 2 is the structural representation of prior art, and as seen from Figure 2, in prior art, the little head end of principal reflection panel 1 is fixed on centerbody by bolt 6, belongs to and is rigidly connected.The back side of principal reflection panel 1 is connected with radiation beam 3 end faces by one group of adjusting device 2, and one end of radiation beam 3 is connected with centerbody 4 sides.To realize and regulating by the flexural deformation of principal reflection panel 1 so prior art is actual, the closer to rigid connecting contact, deflection is less, so the technical problem that prior art exists the scope of about 1～1.2 meter of the little head end of reflecting plate to regulate affects the reflection precision of antenna.
