Description

Cylindrical cam formula geosynchronous satellite antenna

Technical field

The utility model relates to a kind of satellite-signal accepting device, specifically refers to a kind of cylindrical cam formula geosynchronous satellite antenna that can follow the tracks of the numerous satellite-signals of acceptance arbitrarily.

Background technology

At present, the general satellite television receiving antenna of Shi Yonging, antenna surface is fixed, feed is single, can only accept the TV signal of a satellite, and numerous satellite that distributing in the terrestrial equator sky, if change the signal of an other satellite, then take a lot of work in the azimuth and the elevation angle of necessary manual adjustment antenna surface, effort.Work as antenna surface because of people's health screening, acknowledge(ment) signal is descended, control lag, efficient is low, and needs many people cooperating.Because antenna surface all is erected on the top or mountain peak of skyscraper usually, work is dangerous, and labour intensity is big, and operation is extremely inconvenient.Because feed is single, can't select Ku section and C section programme signal simultaneously, when accepting different satellite-signal, feed must correspondingly carry out the polarizing angle adjustment, could accept to maximum gain the signal energy of satellites transmits, therefore, the satellite tv antenna that generally uses at present is difficult to satisfy users' instructions for use.

Summary of the invention

The utility model adopts the bitubular feed that can realize that wave band conversion and polarizing angle are adjusted, the elevation angle control and the automatic adjusted in concert of azimuthal control of antenna surface, and the TV signal of numerous satellites is accepted on easy, accurate, maximum gain ground.

The utility model is achieved in that two tuners (29) are respectively Ku section and C section feed, and they are arranged side by side in bitubular feed [3] inside, and the cover top portion of bitubular feed [3] is equipped with arc-shaped rack [27], and its shell one side is contained on the jointed shaft [25].Dumpling connects axle [25] and is contained on the feed support [23], and two limit switches [24] and wave band conversion motor [1] also is housed on the feed support [23].On the axle of wave band conversion motor [1] gear [26] is housed.When wave band conversion motor [1] respectively when both direction rotates, driven wheel [26] engagement arc-shaped rack [27], make bitubular feed [3] respectively to the left and right direction swing.The limit off-position of two limit switches [24] guarantees that two tuners [29] accurately swing to the focal position of antenna surface [6], thereby realizes the conversion of wave band.

Parallelogram lindage [28] is housed on two tuners [29], polarizing angle is installed on one of them jointed shaft of parallelogram lindage [28] adjusts motor [2].When polarizing angle is adjusted motor [2] work, drive parallelogram lindage [28] motion, two tuners [29] are rotated simultaneously, thereby realize the adjustment of tuner [29] polarizing angle.

The azimuthal control of antenna surface [6] is achieved in that antenna surface [6] is installed on the swivel mount [11] by jointed shaft [4] and jointed shaft [7].Swivel mount [11] upper end is installed on the column [17] with bearing [5], and swivel mount [11] lower end is connected with driven gear [19], and driven gear [19] is loaded on the column [17] with bearing [18].Column [17] is fixing with support [16].Azimuth drive motors [22] is installed on column [17].Driving gear [20] is installed on the output shaft of azimuth drive motors [22], and symmetry is installed with two spacing day passes [21] on its seat board.When azimuth driving machine [22] was worked, driving tooth [20] horizontally rotated by driven gear [19] driven rotary frame [11], thereby realized the azimuth control of antenna surface [6].The limit off-position of two limit switches [21] guarantees that swivel mount [11] is effectively rotating safely in the azimuth coverage.

The automatic adjusted in concert at antenna surface [6] elevation angle is achieved in that spring guide [10] one ends on the jointed shaft [7] ride on the pulley [9].The downside of spring guide pipe [10] has groove, steel wire rope [12] in the pipe is pulled out from groove, be connected on the slide plate [14] through pulley [9], pulley [15] is housed on the transverse axis of slide plate [14], pulley [15] matches with cylindrical cam track [13] on being fixed on column [17].Slide plate [14] is installed in the slide rail of swivel mount [11].When swivel mount [11] rotated, slide plate [14] was subjected to the restriction of cylindrical cam geo-stationary orbit [13], slide up and down thereupon, so the tractive up and down of steel wire rope [12] to make antenna surface [6] be fulcrum with jointed shaft [4], vertically swing, thus realize the control at the elevation angle.The spring [8] that is placed on the spring guide pipe [10] guarantees that antenna surface [6] can be stabilized in any elevation location.Because the curve of cylindrical cam geo-stationary orbit [13] shapes through accurate Calculation, so when the azimuth controls to a certain accurate angle, swivel mount [11] forces pulley [15] to move to a certain corresponding curve point of cylindrical cam geo-stationary orbit [13], then antenna surface is in elevation location accurately just, thereby has realized antenna surface [6] elevation angle and azimuthal automatic adjusted in concert.

The utility model has been realized a purpose that antenna equipment is followed the tracks of numerous satellites with the easiest electric remote control; Bitubular feed [3] has been realized the conversion and the polarization adjustment of Ku section and C segment signal, can receive to maximum gain different satellite TV signals arbitrarily.
