Abstract
The invention relates to an adjustable microwave polarizer. The adjustable microwave polarizer can be used for deflecting a polarization direction of a microwave electromagnetic field. The adjustable microwave polarizer comprises two waveguide tubes, wherein the cross sections of tube holes of the two waveguide tubes are rectangular, and an included angle is formed between the longitudinal centre lines of the cross section rectangles of the tube holes of the two waveguide tubes. A polarization block is arranged between the adjacent ends of the two waveguide tubes, an axial hole is formed at the centre position of the polarization block, and the cross section of the axial hole is rectangular. The adjustable microwave polarizer is characterized in that two arc grooves are arranged on one surface of the polarization block, and the two arc grooves are located at the outer side of the axial hole as well as oppositely and symmetrically arranged. Two pins are arranged between the polarization block and one waveguide tube, one end of each pin is fixed on the adjacent end of the waveguide tube opposite to the two arc grooves, and the other end of each pin is slidably arranged in the two arc grooves on one surface of the polarization block. By utilizing the adjustable microwave polarizer, the risk of aerial work can be decreased; moreover, the adjustable microwave polarizer is high in installation accuracy and good in microwave polarization effect.
Description
Technical field
The present invention relates to a kind of microwave device.Specifically, be to can be used to adjustable microwave polarizer that the microwave electromagnetic field polarised direction is deflected, be applicable to the connection between two waveguides that polarised direction is different in the microwave communication field.
Background technology
On microwave communication equipment, the microwave polarizer that is used for the microwave electromagnetic field polarised direction is deflected all is a traditional product at present.This traditional microwave polarizer generally comprises two waveguides and is no less than one polarization piece, and the junction of polarization piece between two waveguides adopted screw to be detachable shape and be fixed together between them.The center of polarization piece is processed with axial hole, and the cross section of the pore of said axial hole and waveguide is rectangle, between the rectangular longitudinal centre line of cross section of the axial hole on the polarization piece and the pore of waveguide angle is arranged all.Like this, microwave electromagnetic field can change its polarised direction after passing through from the axial hole of polarizer.
There is following problem in said structure:
1. because the microwave polarizer all is installed in higher place usually; When the polarised direction of microwave polarizer need change; The screw that must will connect waveguide and polarization piece unloads, and the piece that will polarize again rotates a certain angle, and then with screw waveguide and polarization piece is locked; Make that the work high above the ground difficulty is big, dangerous high.
2. when adjustment polarized the piece angle, owing to receive the restriction of screw hole positional precision, waveguide was poor with polarization interblock installation accuracy, and the microwave polarization effect is affected.
Summary of the invention
The problem that the present invention will solve provides a kind of adjustable microwave polarizer, adopts this adjustable microwave polarizer, can reduce work high above the ground danger, and installation accuracy is high, and the microwave polarization effect is good.
For addressing the above problem, adopt following scheme:
Adjustable microwave polarizer of the present invention comprises two waveguides, and the pore cross section of two waveguides is rectangle, and between the rectangular longitudinal centre line of the cross section of the pore of two waveguides angle is arranged.The polarization piece is arranged between the neighboring terminal of two waveguides, and the centre bit of polarization piece is equipped with axial hole, and the cross section of axial hole is a rectangle.Be characterized on the one side of said polarization piece two deep-slotted chip breakers being arranged, this two deep-slotted chip breaker is positioned at the axial hole outside, and is relative shape symmetric arrangement.Between polarization piece and a waveguide two pins are arranged, an end of this two pin is fixed on the neighboring terminal of that waveguide relative with two deep-slotted chip breakers, and the other end of two pins is the slip shape respectively and places in polarization piece two deep-slotted chip breakers simultaneously.
Wherein, the radian of said two deep-slotted chip breakers is all spent less than 180, thereby makes the polarization piece can be adjusted to any angle as required.
Take such scheme, have the following advantages:
1. owing to can be rotatable shape cooperation through arc groove and pin between the waveguide of adjustable microwave polarizer of the present invention and the polarization piece; When the microwave polarised direction need change; Only need lock-screw with the outside unclamp and need not to unload, the piece that will polarize then rotates to required angle, lock-screw is locked to get final product again; Make that the work high above the ground difficulty is little, danger reduces relatively.
2. owing to can be rotatable shape cooperation through arc groove and pin between the waveguide of adjustable microwave polarizer of the present invention and the polarization piece; In this rotation angle range; The position adjustment does not receive any restriction, thereby makes waveguide high with polarization interblock installation accuracy, and the microwave polarization effect is good.

Embodiment
As depicted in figs. 1 and 2, adjustable microwave polarizer of the present invention comprises that pore 6 cross sections of two waveguide 1, two waveguides are rectangle, and between the rectangular longitudinal centre line of cross section of the pore 6 of two waveguides angle is arranged.Polarization piece 4 is arranged between the neighboring terminal of two waveguides 1, and the centre bit of polarization piece 4 is equipped with axial hole 5, and the cross section of axial hole 5 is a rectangle.Two deep-slotted chip breakers 3 are arranged on the one side of said polarization piece 4, and this two deep-slotted chip breaker 3 is positioned at axial hole 5 outsides, and is relative shape symmetric arrangement.The radian of said two deep-slotted chip breakers 3 is all less than 180 degree, and the radian of two deep-slotted chip breakers 3 is 90 degree in the present embodiment.Polarization piece 4 and 1 in a waveguide have two pins 2, and an end of this two pin 2 is fixed on the neighboring terminal of that waveguide 1 relative with two deep-slotted chip breakers 3, and the other end of two pins 2 is the slip shape respectively and places in polarization piece two deep-slotted chip breakers 3 simultaneously.
During use, the polarised direction to the microwave polarizer changes if desired, only needs the lock-screw of outside is unclamped (need not to unload), and adjustment polarization piece angle gets final product lock-screw locking to desired location at last more then.Whole adjustment process is simple and convenient, and installation accuracy is higher.
