Description
Technical field
The present invention relates to a kind of displacement regulating and amplifying and comprise the antenna for base station that the phase adjusted displacement of phase shifter is amplified of being used for of this device.
Background technology
The angle of declination of antenna of mobile communication base station can be realized by regulating phase shifter.The motion mode of the slide plate of the phase shifter inside of adjusting antenna phase generally rotatablely moves and the rectilinear motion dual mode at present.Fig. 1 adopts the schematic diagram of the phase shifter of rectilinear motion mode for slide plate.As shown in the figure, two free ends of the slide plate 6 of this phase shifter insert fixedly in the guide 7, and the described relatively fixedly guide 7 of described slide plate 6 horizontally slips.Described slide plate 6 is connected with adjusting device by a pull bar 102, drives described slide plate 6 motions by adjusting device, thereby adjusts the variation of described phase shifter input/output terminal phase place.
Fig. 2 is the schematic diagram of existing antenna for base station, and described antenna for base station comprises an orthoscopic phase shifter, and the protective cover and the end cap of described antenna for base station are not shown.Fig. 3 is the scale schematic diagram of the scale 4 of antenna for base station shown in Figure 2, and antenna protection cover 105 and end cap 106 have been shown among Fig. 3.Regulating wheel 5 drive screws 1, screw rod 1 and slide block 2 are threaded, and slide block 2 is connected with the pull bar 102 of phase shifter slide plate by a connector 3.The elongated slot 104 that scale 4 passes on the antenna-reflected plate 101 is fixing with connector 3.Scale 4 passes antenna installation panel 103 and antenna end cap 106 is stretched.Screw rod 1 supports also axial limiting by antenna installation panel 103, makes 1 of screw rod rotate and can not move axially.Therefore as long as rotation regulating wheel 5 just can drive pull bar 102 and move, its distance that moves just can reflect by the length that scale 4 stretches out antenna end cap 106.For this structure, the distance that moves of the distance that scale 4 moves and pull bar 102 and phase shifter slide plate is identical.
When the scale of scale 4 is set, generally be provided with according to the Downtilt adjustable range, the every adjusting of Downtilt is a scale of corresponding scale once.High frequency electrical tilt antenna with a certain model is an example, the Downtilt adjustable range is 0～10 degree, corresponding phase shifter slide plate displacement is 0～22mm, be the every adjusting of Downtilt once, the phase shifter slide plate moves 2.2mm, the also therefore mobile 2.2mm of scale, so the length of a scale of its scale is exactly 2.2mm.Such scale label distance is obviously less than normal, is inconvenient to read, and causes error in reading easily.And general antenna end cap 106 is benchmark of reading scale; in described antenna for base station assembling; described antenna end cap 106 usually can produce assembling deviation; because the length of each scale of scale only is 2.2mm; the assembling deviation of the described relatively end cap 106 of this length is obviously less; also cause the reading of this antenna for base station scale 4 inaccurate, and then increased the phasing error of described phase shifter.

The displacement regulating and amplifying of the embodiment of the invention can be applied in the antenna for base station, and displacement regulating and amplifying as the phase shifter adjusting device, is regulated the phase place of antenna for base station phase shifter.Below in conjunction with accompanying drawing the antenna for base station that comprises displacement regulating and amplifying is specifically described.
Fig. 5 is the schematic diagram of the antenna for base station of one embodiment of the invention, and Fig. 6 is the schematic diagram of the antenna for base station phase shifter adjusting device shown in Fig. 5.As shown in Figure 5 and Figure 6, when displacement regulating and amplifying shown in Figure 4 is applied in the antenna for base station, the 201 usefulness antenna-reflected plates 11 of the base plate shown in Fig. 4 are substituted, second bracing frame, the 203 usefulness antenna installation panels 13 shown in Fig. 4 are substituted.The antenna for base station of present embodiment comprises antenna-reflected plate 11 and orthoscopic phase shifter 15, can also comprise antenna installation panel 13.Described phase shifter 15 is installed on the antenna-reflected plate 11, and antenna installation panel 13 is installed in an end of antenna-reflected plate 11.Antenna installation panel 13 is fixed on the launching tower Metallic rod (not drawing among the figure) by mounting bracket.First slide block 22 is connected with the pull bar 12 of phase shifter slide plate.First slide block 22 can comprise a nut that is threaded on described first screw rod 21, and described nut is fixed on the pull bar 12 of described phase shifter 15 slide plates by a connector 23.The free end of described second screw rod 31 axially is supported on the described antenna-reflected plate 11 by described antenna installation panel 13 with limiting, described scale 34 extends described antenna installation panel 13, make that described scale 34 moves perpendicular to described antenna installation panel 13 along with the moving of described second slide block 32.
Specifically can realize support on the described antenna installation panel 13 by opening circular hole to second screw rod 31.Because the two ends of second screw rod 31 are by first bracing frame 33 and antenna installation panel 13 supports and axial limiting, therefore second screw rod 31 can only rotate, and can not move axially.When rotating regulating wheel 35, described first screw rod 21 and second screw rod 31 rotate synchronously, owing to the pitch of second screw rod 31 pitch greater than first screw rod 21, make the translational speed of second slide block 32 greater than the translational speed of first slide block 22.Because described scale 34 is fixedlyed connected with described second slide block 32, and phase shifter 15 slide plates are connected with first slide block 22 through connector 23 by pull bar 12, the translational speed of described scale 34 and just equal the ratio of the pitch of the pitch of second screw rod 31 and first screw rod 21 apart from the ratio with phase shifter 15 slide plate translational speeds and distance.For example, the pitch of second screw rod 31 is 3mm, and the pitch of first screw rod 21 is 1mm, and then when the mobile 3mm of second slide block 32, the displacement of first slide block 22 is 1mm, so whenever phase shifter 15 slide plates move 1mm, corresponding described scale 34 moves 3mm.Be example with the high frequency electrical tilt antenna equally, the Downtilt adjustable range is 0～10 degree, corresponding phase shifter slide plate displacement is 0～22mm, be the every adjusting of Downtilt once, the phase shifter slide plate moves 2.2mm, the then therefore mobile 6.6mm of scale, so the length of a scale of its scale is exactly 6.6mm, as shown in Figure 7.Compare the scale 4 shown in Fig. 3, the length of each the lattice scale on the scale 34 among Fig. 7 increases, and has made things convenient for reading, is not easy to cause error in reading.And because the length of each scale of scale is 6.6mm, the assembling deviation of described end cap 16 this length relatively can be ignored, thereby has increased the accuracy of reading of this antenna for base station scale 34, and then has reduced the phasing error of described phase shifter.
The above is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as dropping within the desired protection range of claim of the present invention.
