Description

Mobile communication band azimuth circle rotable antenna pole seat

Technical field

The utility model relates to a kind of antenna assembly, especially the fixture of antenna pole.

Background technology

Mobile communication, comprise first generation simulation mobile communcations system, second generation digital mobile communication system, third generation mobile system and following mobile communcations system, it all is to finish by antenna that the signal of system base-station transmits and receives, the antenna height of antenna generally from tens meters to the timely rice.Erection method generally has: ground iron tower, roof iron tower, Guywire tower, simple and easy communications tower or the like.Which kind of erection method no matter, the locate mode between existing antenna and the iron tower is all finished by pole, and promptly antenna is fixedly connected by locating clip and pole, and pole connects with the iron tower solid welding surely by backstay, perhaps is fixed on the flooring.The orientation of antenna is determined and need be realized by the locating clip that adjustment antenna and pole are fixedly connected.

Base station of mobile communication generally is split into three directional cells, and every pair of aerial signal coverage goal of 360 degree is 120 degree in the horizontal direction, adjusts the signal coverage direction and realizes by the antenna azimuth that reverses on the pole.The shortcoming of existing mobile communication pole mainly contains:

Do not have default azimuth when (1) pole being installed, can not embody the designing antenna azimuth;

Can't accurately learn the azimuth after antenna is installed when (2) fixing up an aerial wire, the azimuth accuracy after the installation has only about 10 degree;

(3) in the process of the network optimization, when need adjusting the azimuth, with compass below iron tower tens meters measure, can't accurately adjust to the right place, about adjusting range has only 10 to spend;

(4) Antenna Positioning folder and set bolt get rusty easily, and often are difficult to after getting rusty turn, and influence the adjustment of antenna azimuth in follow-up maintenance, the optimization work.

Summary of the invention

The purpose of this utility model provides a kind of mobile communication band azimuth circle rotable antenna pole seat, can overcome the weak point of existing antenna pole fixture, and the location is accurate, and adjusting range is wide, and the azimuth is adjusted and be easy to maintenance.

The technical solution of the utility model is specially:

A kind of mobile communication band azimuth circle rotable antenna pole seat, it comprises pole and backstay, it is characterized in that also comprising:

Be located at the described guide vane end stop that is fixed on inboard, pole lower end;

Inboard, described pole lower end is inserted in the upper end, the pole seat axle that limited by described guide vane end stop, and both are rotatable socket, a side and the described backstay of this pole seat axle are fixedly connected;

The inboard is fixedly connected with the pole seat axle outside, the relative graduated collar in lower surface top and pole;

One end and the outside, described pole lower end are fixedly connected, and the other end points to the orientation pointer above the described graduated collar;

The dog screw that is located at the pole lower end outside, locatees mutually by screw and inboard pole seat axle.

Described dog screw is one or at interval some.

Also be provided with the ring that keeps off the rain on described dog screw and the pole above the orientation pointer.

Be provided with the azimuth scale corresponding with the orientation pointer on described graduated collar, this azimuth scale can be 0～360 degree.

The mobile communication band azimuth circle rotable antenna pole seat of above structure, after transferring pinidine position screw, can change pole regulate antenna towards, antenna by connector directly weldering be fixed on the pole, removed locating clip.Can simplify task difficulty on the antenna workman tower, make installation, adjustment and the simplification of upkeep operation process, the standardization of antenna and pole, and the azimuth adjusting range is wide to be improved greatly with positional accuracy, reduces the difficulty and the danger of original work high above the ground greatly.

Fig. 3 is the plan structure schematic diagram of Fig. 2.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be the structural representation of existing antenna pole fixture.By among the figure as can be known, antenna pole 2 is fixedly connected with an end of its backstay 1, fixtures such as the other end of backstay 1 and ground iron tower, roof iron tower, Guywire tower, simple and easy communications tower are fixedly connected, the lower end of antenna pole 2 or also be fixedly connected with building or ground.Certainly, backstay 1 also can be established several at interval, to strengthen the stability of pole 2.Antenna 4 connects with pole 2 location by connector 5 and locating clip 3, and the signal lead 6 of antenna is connected with the wireless transmission receiving system.If the direction that will regulate antenna 4, the very important person climbs up pole 2 and unclamps locating clip 3 and adjust, and tightens locating clip after mixing up again.Such antenna pole fixture can't accurately be learnt the azimuth after antenna is installed, installation, adjustment and difficult in maintenance, and the azimuth adjustable extent is little, and fail safe is bad.

Shown in Figure 2, be sectional structure schematic diagram of the present utility model.It is provided with guide vane end stop 11 in the endoporus of the lower end of pole 2 on the basis of Fig. 1, be provided with a pole seat axle 7 sleeves and go in its endoporus, and both are rotatable socket.Be inserted in the endoporus of pole 2 lower ends the upper end of pole seat axle 7, is subjected to the qualification of guide vane end stop 11 above it.One side of pole seat axle 7 and an end of backstay 1 are fixedly connected, and the other end of backstay 1 is fixedly connected with the fixtures such as ground iron tower, roof iron tower, Guywire tower, simple and easy communications tower that are fixedly connected.In the lower end of pole 2 and the outside of pole seat axle 7 socket places, be provided with the dog screw 9 of locating mutually by screw and inboard pole seat axle 7, the mutual location that is used for pole 2 lower ends and pole seat axle 7, another outside of pole 2 lower ends is fixed with an end of orientation pointer 12.Described dog screw 9 can be established some at interval, with the stability of reinforcement pole 2 with the mutual location of pole seat axle 7.Above the backstay 1, be fixed with the dial 8 of annular on pole seat axle 7 outsides corresponding with pole 2 lower surfaces, be provided with the azimuth scale 13 of 0～360 degree above this dial 8, see vertical view Fig. 3 of Fig. 2.Another tip of orientation pointer 12 refers on the azimuth scale on dial 8, is fixed on just the knowing towards pointer at a glance of antenna of pole 2 upper ends, and is very convenient and obvious.In pole 2 lower ends, orientation pointer 12 and above the dog screw 9, be fixed with the ring 10 that keeps off the rain, the etch that protection orientation pointer 12 and dog screw 9 are avoided exposing to the sun and rain.Because the lower end of pole 2 is rotatable socket with pole seat axle 7, and pole seat axle 7 is fixedly connected by backstay 1 and near fixing iron member or building, rotation pole 2 be on its bar of scalable antenna towards the orientation.So antenna 4 can directly weld by connector 5 and be fixed on the pole, has saved locating clip.Like this, if to adjust pole 2 upper end antennas 4 towards the orientation, then to unclamp dog screw 9, the azimuth scale 13 that is provided with above in conjunction with orientation pointer 12 and dial 8, rotate pole 2 and adjust antenna 4 towards the orientation, determine screwed in place screw 9 behind the orientation well, location pole 2 gets final product.
