Abstract
The utility model discloses a dual-beam dual ported feed source for receiving, comprising a basal body that is provided with an installation hole for the basal body installation, two installation cavities for a tuner installation and a horizontal indicating instrument. The orthographic projections of the axes of the two installation cavities forms an angle as the angle of cut of two satellites; the setover of the two installation cavities is a set value; the two installation cavities and the relative feed source technology parameter can not be regulated after being produced. With simple structure and accurate receiving level, the utility model is easy and quick in installation and regulation, which is convenient for mass production.
Description
Technical field:
The utility model relates to parabolic antenna dualbeam reception twoport feed.
Background technology:
At present the dual polarization tuner generally adopts single port with feed on the parabolic antenna, and this single port feed itself need not debugging, thereby easy for installation, but a tuner can only be installed, receive a satellite-signal.Application number provides a kind of " double-fed source dualbeam receives the feed source device of usefulness " for the Chinese patent of 92205956.X, the spacing that this device is regulated two tuners by the adjustment means of activity reaches the angle of cut and the elevation difference of regulating two satellites that receive, so Installation and Debugging difficulty, degree of regulation is low, can't be accepted by users.
The utility model content:
The purpose of this utility model is to provide a kind of Installation and Debugging easy, and the dualbeam that precision is high receives the twoport feed of usefulness.
The utility model comprises a matrix, be useful on the installing hole that matrix is installed, the installation cavity that is used to install tuner on the matrix, be characterized in that matrix is an integral type, horizontal indicator is housed on the matrix, described installation cavity has two, the axis orthographic projection angle of this two installation cavity is the angle of cut of two satellites, and the offset or dish of two installation cavitys is a setpoint distance, and two installation cavitys and between them related feed technical parameter non-adjustable behind production.
In order to reduce shielded area, matrix has the shape of carrying out whole envelope along described installing hole and two installation cavitys.
For ease of observing debug results, described horizontal indicator adopts the horizontal indicator of bubble type.
Because spending with the interior required technical parameter that reaches of two satellite-signals as the offset or dish between two installation cavitys of the utility model dualbeam twoport feed in reception adjacent 10, two installation cavitys are the angle of outer incline vertically, even two installation cavity axis orthographic projection angles equal the angle of cut of two satellites etc., all correlation technique parameters are all made by the requirement that designs when production, product is made has just reached high-precision specification requirement, himself do not need to debug again, equally simple that single star receives is installed together during installation, as long as access the signal of a star, the signal of another star just comes out automatically.Owing on the utility model horizontal indicator has been installed also, Installation and Debugging only need see that the steam bubble of horizontal indicator is in the centre position, debugging is promptly accused and is finished, very convenient, so the utility model Installation and Debugging are very efficient and convenient, the utility model is simple in structure simultaneously, receives the accuracy height, is easy to produce in batches.
Description of drawings:
Fig. 1 is the utility model front view.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Embodiment:
Referring to Fig. 1, matrix 1 is all-in-one-piece, have two installation cavitys 3 that tuner is installed on it, the center of circle of two installing holes 2 distance in the horizontal direction is to design by the angle of cut of two satellites of desire reception, the distance of vertical direction designs by elevation difference, can know in conjunction with Fig. 2 and see that this installation cavity 3 is obliquely installed vertically by mind-set both sides in the end face, the axis orthographic projection angle of two installation cavitys 3 is θ 1+ θ 2, and this value is the angle of cut of two satellites.When packing tuner into installation cavity 3, tuner is fixed, as shown in Figure 1 by screw.Fig. 1 also illustrates, horizontal indicator 4 also is housed on the matrix 1, this horizontal indicator 4 uses when Installation and Debugging, if it is placed in the middle to observe the steam bubble of horizontal indicator 4, illustrate that debugging meets the requirements, otherwise need to continue debugging, matrix 1 also has the minimum area shape of carrying out whole envelope along all installing holes 2 and two installation cavitys 3 in addition, and this is in order to reduce shielded area.
The utility model makes the steam bubble in the horizontal indicator 4 placed in the middle when installing, and arbitrary that aims at simultaneously in two satellites of desire reception gets final product, and the signal of another satellite can come out automatically, need not adjust other parameter again, thereby install very convenient.
