Abstract
The utility model discloses a connecting structure capable of improving a main reflection surface precision of an antenna. The connecting structure comprises a group of main reflection panels (1); the bottoms of the main reflection panels (1) are connected with a radiation beam (3) by a group of adjusting assemblies (2); and the radiation beam (3) is connected to and fixed at the side of a central body (4) by a bolt. Small head ends of the main reflection panels (1) are connected with the top surface of the central body (4) by a newly-added adjusting assembly (5). According to the scheme, the existing fixed bolt is removed; and the newly-added adjusting assembly is used to connect the small head ends of the main reflection panels with the top of the central body, thereby solving a technical problem that the small head ends of the main reflection panels can not be adjusted in a range of 1 to 1.2 meters in the prior art. Because the main reflection panels are supported completely by the adjusting assemblies based on the improved structure, the main reflection panels is in a complete suspension state; and deformation of the main reflection panels can be prevented during the adjusting process, thereby prolonging the service lives of the main reflection panels.
Description
Technical field
the utility model relates to a kind of syndeton that improves antenna main reflector precision, belongs 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.By adjusting device, can regulate principal reflection panel angle, 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 purpose of this utility model is, a kind of syndeton that improves antenna main reflector precision is provided, and changes being rigidly connected between principal reflection panel microcephaly end and centerbody into floating connection mode, to overcome the deficiencies in the prior art.
the technical solution of the utility model:
a kind of syndeton that improves antenna main reflector precision of the present utility model 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 utility model changes being rigidly connected between principal reflection panel microcephaly end and centerbody into floating connection mode to the utility model.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 utility model;
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 utility model is described in further detail, but not as to any restriction of the present utility model.
embodiment of the present utility model: the utility model is constructed according to following a kind of method of attachment that improves antenna main reflector precision, the method can be directly used in improves enforcement to large-scale antenna of the prior art, the method is when 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 antenna main reflector precision by this method.
the of the present utility model a kind of syndeton that improves antenna main reflector precision building according to said method is, 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.So prior art is actual, be that flexural deformation by principal reflection panel 1 realizes and regulating, 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.
